  Citation × Citation Citation Abstract Copy Title: Historical Vegetation of Three Salmon-Bearing Watersheds in the Interior Columbia River Basin Author: Smith, Tyanna Year: 2014 Land use practices can be a contributing factor to environmental degradation and have been the focus of many ecological studies. One aspect that is less addressed is land use history and the effects that past practices, such as logging and grazing, can have on the current landscape. This paper describes research and the synthesis of material on the environmental history and watershed characteristics for three watersheds located within spawning and rearing areas for Chinook salmon in the Grande Ronde River Basin in Northeast Oregon: upper Grande Ronde River, Catherine Creek, and Minam River. The Grande Ronde Basin is critical spawning and rearing habitat for salmonids listed under the Endangered Species Act. The primary historical data sources for reconstructing 19th century stream and riparian conditions are the General Land Office township survey notes from 1863 - 1901. Data about the habitat conditions of the landscape were extracted from notes of each township survey source regarding vegetation, stream crossings, and other features found on the landscape in tabular and spatial forms. Data were organized to describe common stream and riparian conditions for the historical time period using a geographic information system. Watershed basin, Chinook salmon life history, ecoregion and surveyor were analyzed using multivariate techniques to determine which parameters were strongly connected to historical vegetation. Ecoregion had the strongest correlation with plant communities. For future research, these historical data could be compared to current habitat survey data, such as the Oregon Department of Fish & Wildlife’s Aquatic Habitat Inventories, to evaluate the degree of change over time of stream and riparian conditions.

  Citation × Citation Citation Abstract Copy Title: The Impact of Fine Sediment on Stream Macroinvertebrates in Urban and Rural Oregon Streams Author: Hoy, Raymond S. Year: 2001 Urbanization, often characterized by high impervious surface area, can result in excessive inputs of fine sediments into urban streams. Excessive fine sediments can blanket the stream bed filling the interstitial space in the substratum, which may have adverse effects on stream biota. A field survey was conducted in Oregon urban and non-urban basins to investigate the relationship between fine sediments and stream macroinvertebrates. Physical, chemical, and biological data were collected from 59 stream sites in two urban and two rural streams. The stream sites fulfilled a continuous sediment gradient, which ranged from a low of 2% of fine sediment in the substrate to a high of 64% with an average of 22%. The % fines, in Clear Creek (rural basin) was significantly lower than in the urban basins (Johnson Creek and Tryon Creek) (p=0.005). Johnson Creek (mean=23%) had approximately three times more fine sediment than Clear Creek (mean=7%), while Tryon Creek (mean=32%) had nearly five times as much fine sediment as Clear Creek. EPT taxa richness was significantly higher in both rural streams than in both urban streams (p0.05). For example, regression analysis of EPT taxa richness vs. % fine sediments displayed a coefficient of determination (r2) value of 0.2. Other macro invertebrates metrics displayed similar patterns. The lack of significant correlations may be due to the cumulative effect of basin-wide "historical land use past". Past land use activity may have resulted in long-term reductions of sensitive taxa in the basin taxa pool and efforts to improve local habitats may not be quickly colonized by pollution sensitive taxa. Long-term degradation to the urban streams resulted in a relatively homogenous assemblage of macro invertebrates, which may have confounded the quantitative relationship between sediments and macroinvertebrates. This study suggests there is a clear difference between urban and non-urban streams in terms of macro invertebrates, which may be likely due to sediments, but the quantitative relationship between fine sediments and macro invertebrates is weak.

We used ensemble climate change scenarios, a hydrologic model, a stream channel survey, a hydraulic model, and a travel forecast model to develop an integrated impact assessment method. High-resolution climate change scenarios are based on the combinations of two emission scenarios and eight general circulation models. The Precipitation-Runoff Modeling System was calibrated and validated for the historical period of 1988 and 2006 and simulated for determining the probability of floods for 2020 through 2049. We surveyed stream cross-sections at five road crossings for stream channel geometry and determined flood water surface elevations using the Hydrologic Engineering Centers River Analysis System (HEC-RAS) model. Four of the surveyed bridges and roadways were lower in elevation than the current 100-year flood water surface elevation, leading to relatively frequent nuisance flooding. These roadway flooding events will become more frequent under some climate change scenarios in the future, but climate change impacts will depend on local geomorphic conditions. Whereas vehicle miles traveled was not significantly affected by road closure, vehicle hours delay demonstrated a greater impact from road closures, increasing by 10 percent in the Fanno Creek area. Our research demonstrated the usefulness of the integration of top-down and bottom-up approaches in climate change impact assessment and the need for spatially explicit modeling and participatory planning in flood management and transportation planning under increasing climate uncertainty.

  Citation × Citation Citation Abstract Copy Title: Stream-Associated Amphibian Habitat Assessment in the Portland-Vancouver Metropolitan Region Author: Dietrich, Andrew Evans Year: 2012 This study assessed the influence of landscape development on stream-associated amphibians in forested riparian areas within the Portland-Vancouver metropolitan region. Human alteration of landscapes may dramatically affect the ecology of neighboring aquatic systems. It was hypothesized that lotic amphibians would be negatively associated with greater amounts of landscape development and positively associated with forested area within the surrounding watershed. Thirty-seven 1st-3rd order streams were sampled between June 21st and September 21st in 2011. Streams potentially providing adequate habitat for stream-obligate amphibians were randomly selected. Amphibians were surveyed along 30-meter stream transects using an active-cover search (ACS). Environmental variables associated with development in surrounding landscapes were measured in situ. GIS delineation was conducted to define landscape-scale variables at stratified distances from riparian networks up-stream of each site via the utilization of the 2006 NLCD dataset and a finer-scale, regional dataset compiled by the Institute for Natural Resources (INR). Amphibians were detected at seventeen of the thirty-seven sampled streams. The most commonly detected species were Dicamptadon tenebrosus, Plethadon vehiculum and Plethadon dunni. Streams where amphibians were observed had lower average water temperature and conductivity, coarser stream substrate and were located on public property more often than streams where no amphibians were detected. Landscape variables were most significant to amphibians within 100 and 200 meters of the upstream stream network. Occupancy of a site by facultative species was best explained by the proportion of mixed forest in the surrounding watershed (R2=0.343, p<0.001). Occupancy of a stream by obligate species was best predicted by measurements of water quality and in-stream cover (Water Temperature: R2=0.275, p<0.001; Water Conductivity: R2=0.248, p<0.001; Cover: R2=0.323, p<0.001). Occupancy of stream refugia by all observed amphibians was positively influenced by higher percentages of forest cover and lower percentages of urban development and herbaceous vegetation in the surrounding watershed. Results of this study indicate that urban refugia must contain adequate riparian forest area, coarse stream substrate and clean, cool water to sustain stream-amphibian communities. Protection of remnant forested headwater stream networks is essential to the conservation of lotic amphibians in this urbanized region.

  Citation × Citation Citation Abstract Copy Title: Riparian Shade Assessment and Restoration Priorities Analysis in the Damascus Urban Growth Boundary Expansion Area Author: Leferink, Robin K. Year: 2007 An important component of progressive urban planning is the protection and restoration of riparian environments, particularly in the Pacific Northwest where increasing stream temperatures threaten the survival of endangered salmonids and other cold-water biota. Restoration projects are often led by watershed councils or other grassroots organizations with limited resources, and it is essential that these groups have an efficient and effective approach to determine priority areas where their efforts can be directed to achieve the greatest ecological benefit. The purpose of this project was to quantify existing riparian shade levels and identify priority reaches for shade restoration on Clackamas River basin streams in the Damascus area expansion of the Portland, Oregon urban growth boundary. Additionally, potential errors in the Metro Regional Land Information System (RLIS) Lite geographic information system (GIS) coverage of the area’s streams were identified and corrected where possible. Riparian shade levels were quantified through interpretation of digital aerial photographs using GIS. At the start of the shade analysis six 50 m reaches in the study area were surveyed using a spherical densiometer to calibrate the aerial photo interpretation. Following the analysis, the method accuracy was assessed by comparing GIS-derived shade classes with field data from 25 sites in the study area that were surveyed in 2003. Stream reaches were identified and prioritized for restoration based on riparian shade level, presence or absence of late-summer flow (as determined through field investigations), and GISevaluated stream aspect (i.e. the direction of stream flow). Generally, the headwaters were found to have less shade than the downstream areas and many of the headwater reaches were identified as the highest restoration priority. Of the 60.5 km of streams assessed in the riparian shade analysis, 24.7 km were identified as potential restoration reaches based on shade levels and late-summer flow conditions. These 24.7 km were further broken into five priority ranks, with 4.1 km of stream reaches assigned to the highest shade restoration priority class. Potential errors in the GIS stream coverage were identified in conjunction with the riparian shade assessment. Where possible, these errors were corrected based on the aerial photographs. Although in many cases access was limited, a total of 18 site visits were made to verify stream locations. The results of this watershed-scale restoration priorities analysis are being used by Clackamas River Basin Council and others to guide restoration planning in the new urban area. While focusing on the high priority stream reaches identified, restoration managers will also need to consider reach-scale factors including land use plans, riparian continuity, parcel size, and landowner cooperation in the final selection of restoration sites. The GIS stream layer corrections were provided to Metro and to the City of Damascus for use in their 2007 natural resource inventory.

  Citation × Citation Citation Abstract Copy Title: An Evaluation of Data Collected by Middle School and College-Level Students in Stream Channel Geomorphic Assessment Author: Lafrenz, Martin D. Year: 2013 This project tested the accuracy and repeatability of geomorphic stream channel assessments conducted by two different middle school classes from the Walt Morey Middle School in Troutdale, OR and college students from Portland State University in Portland, OR. Each group surveyed the same three cross-sections in Fairview Creek, a tributary to the Lower Columbia River, in order to assess stream channel geometry, discharge, composition of the bed material, and water quality. The three student groups were all able to accurately document the stream channel geometry, including stream width and mean depth, indicating that these data can be successfully collected by volunteers of various ages. However, stream velocity obtained using the float method was consistently overestimated leading to a biased calculation of discharge, and the low precision of the measurements did not allow for a correction of the bias. The median particle size of the bed material determined by a pebble count was also overestimated by each group, but the low precision also negated the possibility of correcting the estimate. The stored fine sediment in the bed was underestimated by each group and again with low precision. The temperature, pH, and conductivity measured with a calibrated multimeter were accurate and precise for all groups.

  Citation × Citation Citation Abstract Copy Title: Evaluating the Effects of Road Crossing Structures on Stream-Associated Amphibians in the Wilson River Watershed, Tillamook State Forest, Oregon Author: Twitchell, Sara Erin Year: 2013 As replacement and removal of undersized culverts gains momentum as an effective technique for restoring natural stream flows and removing fish passage barriers, it is important to evaluate the benefits of these efforts on the in-stream and adjacent riparian habitat for other species of potential concern. This study compares stream-associated amphibian (SAA) occurrence in streams adjacent to different road crossing structures on unpaved forest roads in the Wilson River watershed located within the Tillamook State Forest, Oregon. Surveys were conducted at road crossing structures for three taxa of SAA; Pacific giant salamander (Dicamptodon tenebrosus), coastal tailed frog (Ascaphus truei), and Columbia torrent salamander (Rhyacotriton kezeri). Statistical models were created to analyze the effect of habitat variables on SAA occupancy, and determine whether those variables changed relative to road crossing structures. Results showed that coastal tailed frog occupancy was positively associated with dissolved oxygen and crayfish presence, negatively associated with longitude, and had a slight quadratic relationship to channel confinement. Because all sites were highly saturated with oxygen, percent dissolved oxygen was likely a surrogate for one or more other covariates, such as in-stream habitat or substrate size. Detection rates of Pacific giant salamander were too high and detection rates of Columbia torrent salamander were too low to provide reliable models, but they did provide some insight into the factors affecting occupancy in the study area, including information about their interactions with road crossing structures. Occupancy rates of Pacific giant salamanders in the study area appear to be unaffected by road crossings, fish passable or otherwise. Conversely, torrent salamanders seemed to be mostly absent from the study sites altogether, but based on the one stream where they were detected, they are not excluded from occupying fish barrier culvert sites. Top weighted habitat covariates, including dissolved oxygen, channel confinement, crayfish and fish presence, and flow constriction are all indicators of disturbance that can be linked to road crossings. Although the size and structure of road crossings did not prove to significantly influence SAA occupancy, indicators of stream disturbance that can be related to road crossings were included in the best models for predicting occupancy, demonstrating the importance of reducing disturbance related to road crossings on streams.

  Citation × Citation Citation Abstract Copy Title: Effects of Spatially Distributed Stream Power on Check Dam Function in Small Upland Watersheds: A Case Study of the Upper Laja Watershed, Guanajuato, Mexico Author: Herzfeld, Zachary Andrew Year: 2017 Watershed restoration comes in a variety of forms depending on which set of problems are sought to be remedied. Severe soil erosion, in the form of gullying and/or headcutting, can be mitigated through constructing check dams in well-selected locations. This practice has been used throughout the upland subwatersheds within the Upper Laja River watershed in Guanajuato, Mexico. The present study employed Wolman pebble counts to systematically assess the effectiveness of 21 check dams located near the city of San Miguel de Allende. Particle size distributions taken directly downstream and upstream of each check dam were differentiated, aggregated and compared--with the difference between median particle size of downstream and upstream distributions defined as DsD50-UsD50. Several subwatershed attributes were calculated in a GIS for comparison to DsD50-UsD50 values. Results indicate that, on aggregate, the check dams studied were moderately successful at retaining sediment that becomes entrained in concentrated flow (DsD50-UsD50 = 15.4 mm; p < 0.001). Individually, 18 of the 21 check dams surveyed had statistically significant differences between DsD50 and UsD50 (p < 0.05). The subwatershed variables of local channel slope (r = 0.55), mean subwatershed slope (r = 0.46), subwatershed area (r = 0.59), distance from channel head (r = 0.54), percent canopy cover (r = 0.46), Qmed (r = 0.46), total stream power (r = 0.58), and change in total stream power (r = -0.45) were found to be statistically significant when correlated with DsD50-UsD50 values (p < 0.05). Change in total stream power was used to classify stream reaches as either erosion or deposition-dominated. When compared, the DsD50-UsD50 values from check dams located in erosion and deposition-dominated reaches are statistically different (p < 0.05); higher performing check dams were predominantly found in deposition-dominated reaches. The results of this study suggest that spatially distributed stream power can be used as a variable for making decisions about future check dam locations. In particular, check dams are more likely to be effective if they are located within deposition-dominated areas (negative change in total stream power) and in areas of decreasing change in total stream power. In general, this study's findings also support locating check dams in second order streams. Title: Effects of Spatially Distributed Stream Power on Check Dam Function in Small Upland Watersheds: A Case Study of the Upper Laja Watershed, Guanajuato, Mexico Author: Herzfeld, Zachary Andrew Year: 2017 Watershed restoration comes in a variety of forms depending on which set of problems are sought to be remedied. Severe soil erosion, in the form of gullying and/or headcutting, can be mitigated through constructing check dams in well-selected locations. This practice has been used throughout the upland subwatersheds within the Upper Laja River watershed in Guanajuato, Mexico. The present study employed Wolman pebble counts to systematically assess the effectiveness of 21 check dams located near the city of San Miguel de Allende. Particle size distributions taken directly downstream and upstream of each check dam were differentiated, aggregated and compared--with the difference between median particle size of downstream and upstream distributions defined as DsD50-UsD50. Several subwatershed attributes were calculated in a GIS for comparison to DsD50-UsD50 values. Results indicate that, on aggregate, the check dams studied were moderately successful at retaining sediment that becomes entrained in concentrated flow (DsD50-UsD50 = 15.4 mm; p < 0.001).

Berry, McKnight, Diane M., Vaughn, Bruce H., Fountain, Andrew G., Dowling, Carolyn Year: 2006 The hydrologic system of the coastal McMurdo Dry Valleys, Antarctica, is defined by snow accumulation, glacier melt, stream flow, and retention in closed-basin, ice-covered lakes. During the austral summers from 1993-1996 and 1999-2000 to 2002-2003, fresh snow, snow pits, glacier ice, stream water, and lake waters were sampled for the stable isotopes deuterium (D) and 18O in order to resolve sources of meltwater and the interactions among the various hydrologic reservoirs in the dry valleys. This data set provides a survey of the distribution of natural water isotope abundances within the well-defined dry valley hydrologic system in Taylor Valley, which extends 20 km inland from McMurdo Sound. The three major Taylor Valley lakes are not connected to one another hydrologically, and their levels are maintained by glacial meltwater inflow and perennial ice-cover sublimation. At the valley scale, glacial ice, snow, stream, and lake waters become more depleted in delta D with increasing distance from McMurdo Sound (further inland). Snow pack in glacial accumulation zones is heterogeneous, likely a result of varying storm sources (continental versus coastal), and, in general, snow pits, fresh snow samples, and glacier ice are more depleted than stream waters. Within the lake basins, glacial ice source waters are depleted by as much as 111ppm delta D and 20 ppm delta 18O compared to lake waters. These results demonstrate the importance of in-stream fractionation at the valley scale. In-stream fractionation occurs through direct evaporation from the channel and hyporheic exchange with isotopically enriched waters in the near-stream subsurface during transport from the glacial source to lake. Furthermore, the results show that lake waters directly reflect their glacial ice sources, despite fractionation during stream transport. Inter-annual comparisons of lake profiles suggest that lake waters are directly influenced by the isotopic composition and amount of stream flow during a season.

  Citation × Citation Citation Abstract Copy Title: Origin of surface undulations at the Kamb Ice Stream grounding line, West Antarctica Author: Seifert, Fiona Bronwyn Year: 2012 The West Antarctic Ice Sheet is drained primarily by five major ice streams, which together control the volume of ice discharged into the ocean across the grounding line. The grounding line of Kamb Ice Stream (KIS) is unusual because the ice stream upstream of it is stagnant. Here, a set of surface features--shore-parallel, long wavelength, low amplitude undulations--found only at that grounding line are examined and found to be "pinch and swell" features formed by an instability in the viscous deformation of the ice. When a relatively competent layer is surrounded by lower strength materials, particular wavelength features within the layer may be amplified under certain layer thickness and strain rate conditions. The undulations at KIS grounding line are possible due to the relatively large strain rates and particular ice thickness at that location. Several data sets are used to characterize the surface features. High resolution surface profiles are created using kinematic GPS carried on board a sled that was used to tow ice penetrating radar equipment. The radar data are used to examine the relationship between surface shape and basal crevasses. Additional surface profiles are created using ICESat laser altimeter observations. Repeat GPS surveys of a strain grid across the grounding line yields strain rate information. Analysis of repeat observations over tidal cycles and multi-day intervals shows that the features are not standing or traveling waves. Together, these observations are then used to evaluate the contributions of elastic and viscous deformation of the ice in creating the grounding line undulations.

Year: 2017 This study analyzed how consumers evaluate online music streaming services through a discrete choice survey. A multinomial logit model was applied to estimate how important varying levels of price, artist welfare, and advertisements were to consumers’ willingness to pay (WTP) for a monthly subscription service to a digital music catalogue. The survey was administered online, with 100 total valid samples. Respondents viewed the morality of copying and distributing copyrighted digital music as different from the physical theft of private property. The most important factors in deciding a respondent’s WTP for service were: the welfare of the artists who list their music on the website, whether the service had advertisements, and the household income of the respondent. Consumption characteristics such as how much a respondent spends on music a month, or how much time they spend listening to music did not have a discernible effect on their WTP.

  Citation × Citation Citation Abstract Copy Title: Evaluation of strain rates on Ice Stream B, Antarctica, obtained using differential GPS Author: Hulbe, Christina L., Whillans, I. M. Year: 1994 The "stop-and-go" kinematic Global Positioning System (CPS) technique was used to survey 270 stations twice within a 25 km by 10 km strain grid on the surface of Ice Stream B. One or two geodetic quality receivers operated as reference pivots, while two similar receivers traveled to grid stations. Each station was occupied for 25 s. The method is rapid and reliable. Each survey was completed within 2 weeks. Calculated horizontal strain rates are accurate to 1%. Relative vertical velocities are accurate to 20 mm kmI a-1. Maps of the four horizontal velocity gradients, relative vertical velocity and surface elevation are presented. The vertical velocity pattern is used to identify the part of the topography that forms stationary waves and that which is migrating. No strong quantitative link is found between the pattern in horizontal strain rate and surface topography. In particular, there is no evidence that the topography is relaxing toward isostasy. None of the "weir-type" sticky spots, which are commonly observed with other glaciers, is found but there could be two of the "submerged-boulder type", which cause lateral flow diversion. Evidence for "hot stripes" and zones of preferred crystal orientation is not found.

Many native salmonid populations have declined in abundance since the early 1900s due to a variety of climate- and human-driven forces. Westslope Cutthroat Trout are especially sensitive to habitat loss or degradation and to climate change. Together, climate change, habitat degradation, and non-native salmonid invasions are contributing to increasingly fragmented WCT populations. Ongoing and predicted future warming trends are expected to further fragment these populations and isolate them in headwater stream reaches, with populations in the spatial margins of their distributions facing greater risk. Native salmonid populations are often separated or isolated by natural or artificial upstream migration barriers (i.e., waterfalls, culverts, etc.). Prior to continuing conservation and management actions targeting WCT, it is imperative to understand habitat requirements of this keystone species in fragmented areas. Field survey data were collected in the summer of 2015 on channel geomorphic characteristics and WCT presence/absence in 26 streams located in the Colville National Forest. A clear spatial separation was observed between Eastern Brook Trout (Salvenius fontinalis, EBT) and WCT above four culvert road crossings and the habitat in both of these areas was compared statistically to identify explicit differences. This dataset was also analyzed using logistic regression modeling to determine the best habitat predictors of the presence of isolated WCT populations existing upstream of these crossing. In general, stream habitat in the Middle and South Forks of Mill Creek had low large substrate, high fine sediments, and exhibited pool-riffle channel morphology. Pool habitat supporting isolated WCT was significantly smaller, in terms of volume and surface area, than pool habitat supporting sympatric populations of WCT and EBT, largely due to the headwater nature of channel units supporting isolated WCT populations. Additionally, due to the extreme drought conditions during 2015, stream flow was substantially diminished in the study area causing these reaches to be highly fragmented and largely disconnected from the rest of the stream channel. Fine sediments were generally higher in headwater reaches supporting isolated WCT, including in pools and riffles, which was unexpected, mainly because they exist above sediment delivery points in the longitudinal extent of the system. Logistic regression analysis indicated that the presence of isolated WCT populations was primarily positively associated with an increase in large wood and boulders, and negatively associated with increasing gravel, bedrock, habitat unit length, depth, and width (Significant x2, R2=0.174, misclassification rate = 14.9%, α=0.05). The final model correctly predicted 37.5% of isolated WCT presence observations and 96.5% of the WCT/EBT presence observations significantly better than by chance alone (k=0.81). This model, in fact, may be useful in identifying limited habitat due to the fragmented nature of the channel units supporting IWCT. Large wood and boulders were positively correlated to WCT presence, likely because both are important in the formation of pools and cascades. Channel unit length, width, depth, active channel width as well as gravel and bedrock substrates, were all negatively associated with WCT presence. This suggests that isolated WCT are primarily associated with small headwater cascades with complex shelter, which may provide greater thermal and predation refuge compared to shallow glide or large pool habitats. Future model analysis should include additional habitat variables such as water temperature, stream gradient, and species interactions to strengthen the prediction of Westslope Cutthroat Trout presence. Overall, I concluded that differences in stream habitat above and below blocking culverts are not driving Westslope Cutthroat Trout distributions in the study area due to confounding factors such as the presence of problematic barriers and small sample size. I also conclude that future conservation and management decisions specific to WCT should prioritize complex cascade habitat in headwater stream reaches because of the type and quantity of habitat they may provide, especially during severe drought or low flow conditions.

  Citation × Citation Citation Abstract Copy Title: The use of junior historical fiction in the classroom Author: Pelinka, Darlene Year: 1972 The use of American historical fiction in an eighth grade social studies or language arts class has not been fully explored, so its literary and social science value is questionable. In order to establish its worth and methods for its use, research into desirable 1iterary goals for adolescents, implications and purposes of historical fiction in general and for youth in particular, a bibliography of novels, and an evaluative survey of specific novels written for youth needed to be done. The research indicates that some critics believe that most junior novels have little to offer youth and that they are poorly written. A minority find that they are useful as an example of a literary genre and as a model for the exploration of adolescent problems, frustrations, and decision making alternatives. Opinions on the value of historical fiction also vary. Some writers conclude that it is largely romantic and a reflection of contemporary times in historical dress, while others have indicated that it conveys an emotional and spiritual feeling for an era through its presentation of historical figures and events and student involvement. Many writers on the subject are ambitious when they consider what junior novels and junior historical novels should accomplish. They list a variety of personal, literary, and conceptual goals. They itemize suitable aims for students such as character building, personal problem solving, an understanding of the mechanics of plot and characterization, an understanding of historical events, and the motivations of figures involved in them, a "feeling" for an era, knowledge of our democratic heritage, even an understanding of what history means. This survey and analysis of specific novels chosen from different American historical eras explores the pertinence of these opinions and goals to novels and briefly verifies the historical accuracy. Part Three handles the problem of methods of use and adaptation in the classroom by specifying alternatives for teachers' consideration. The survey determines that junior American historical fiction is useful to study as a literary genre, though imperfect. If it is used, students must be aware of the imperfections; principally shallow character development or inadequate and overly romantic plots. As a model of personal relevance to youth, historical fiction is not outstanding even though nearly half of the novels contain obvious efforts to build character and several have a theme about growing up. The historical value in these novels varies; most are largely romantic with contemporary main characters who cannot control their situations but can control their destinies. Some provide historical data that gives the reader an insight into specific events, historical figures, or the emotional feelings prevalent during an era. The themes in half the novels stress the issues of the times in which they are set. The surveyed novels include examples of political, social, psychological, economic, religious, cultural, and great man interpretations of history. Social and psychological interpretations predominate, and a majority imply that societies rather than people make history. This survey concludes that junior American historical fiction is relevant for classroom use. Teacher familiarity with the novels and his continuing exploration of divergent applications for use by individual students or classes can make them successful, informative, and enhance student interest in history.

Sustainability education can be implemented in outdoor programs such as nature summer camps in order to build environmental stewardship and ecological literacy in counselors and campers. This study sought to determine the extent to which an ecology and leadership training given to assistant counselors at Tryon Creek State Natural Area day camp achieved the goals of sustainability education--for the assistant counselors to learn about ecology, develop stewardship attitudes and behaviors toward the environment, and become positive role models for the campers in their care. Knowledge and environmental stewardship attitudes and behaviors of the counselors were assessed using surveys, interviews, and training journals. A statistically significant difference was found between pre and posttest scores on a survey measuring knowledge of Pacific Northwest ecology, but no significant difference was found between the pre and posttest scores on an environmental attitudes survey, possibly due to a ceiling effect. Interviews revealed that participants learned about invasive species, Oregon flora and fauna, and stream ecology over the summer. Despite the results on the attitudes survey, interviewees reported greater environmental awareness at the end of the summer as well as a greater sense of place in nature and a desire to continue working with children in an outdoor setting. Title: Sustainability Education as a Framework for Enhancing Environmental Stewardship in Young Leaders: An Intervention at Tryon Creek Nature Day Camp Author: Lawrence, Andrea Nicole Year: 2012 UNESCO established Sustainability Education as a top priority when it declared 2005 - 2014 to be the global decade for sustainability. Sustainability education can be implemented in outdoor programs such as nature summer camps in order to build environmental stewardship and ecological literacy in counselors and campers.

  Citation × Citation Citation Abstract Copy Title: Large Woody Debris Mobility Areas in a Coastal Old-Growth Forest Stream, Oregon Author: Bambrick, Beth Marie Year: 2013 This study uses a spatial model to visualize LWD mobility areas in an approximate 1km reach of Cummins Creek, a fourth-order stream flowing through an old-growth Sitka spruce-western hemlock forest in the Oregon Coast Range. The model solves a LWD incipient motion equation for nine wood size combinations (0.1m, 0.4m, 1.7m diameters by 1.0m, 6.87m, 47.2m lengths) during the 2-year, 10-year, and 100-year discharge events. Model input variables were derived from a combination of field survey, remotely sensed, and modeled data collected or derived between June 2010 and July 2011. LWD mobility map results indicate the 2-year discharge mobilizes all modeled diameters, but mobile piece lengths are shorter than the bankfull channel boundary. Mobility areas for each wood size combination increases with discharge; 10-year and 100-year discharge events mobilize wood longer than average bankfull width within a confined section of the main stem channel, and mobilize LWD shorter than bankfull width within the main stem channel, side channels, and floodplain. No discharge event mobilizes the largest LWD size combination (1.7m / 47.2). Recruitment process was recorded for all LWD during June 2010, revealing that all mobile wood in the study reach was shorter than bankfull width. Based on these conflicting results, I hypothesize the distribution of wood in Cummins Creek can be described in terms of discharge frequency and magnitude, instead of as a binary mobile/stable classification. Mobility maps could be a useful tool for land managers using LWD as part of a stream restoration or conservation plan, but will require additional calibration.

Year: 2014 Surface water and air volatile organic compound (VOC) data from 10 U. S. Geological Survey monitoring sites were used to evaluate the potential for direct transport of VOCs from the atmosphere to urban streams. Analytical results of 87 VOC compounds were screened by evaluating the occurrence and detection levels in both water and air, and equilibrium concentrations in water (C-w(s)) based on the measured air concentrations. Four compounds (acetone, methyl tertiary butyl ether, toluene, and m- & p-xylene) were detected in more than 20% of water samples, in more than 10% of air samples, and more than 10% of detections in air were greater than long-term method detection levels (LTMDL) in water. Benzene was detected in more than 20% of water samples and in more than 10% of air samples. Two percent of benzene detections in air were greater than one-half the LTMDL in water. Six compounds (chloroform, p-isopropyltoluene, methylene chloride, perchloroethene, 1,1,1-trichloroethane, and trichloroethene) were detected in more than 20% of water samples and in more than 10% of air samples. Five VOCs, toluene, m- & p-xylene, methyl tert-butyl ether (MTBE), acetone, and benzene were identified as having sufficiently high concentrations in the atmosphere to be a source to urban streams. MTBE, acetone, and benzene exhibited behavior that was consistent with equilibrium concentrations in the atmosphere.

  Citation × Citation Citation Abstract Copy Title: Temporal Variations of Citizens’ Demands on Flood Damage Mitigation, Streamflow Quantity and Quality in the Korean Urban Watershed Author: Hong, Change-Yu, Chung, Eun-Sung Year: 2016 Sustainable watershed management (SWM) can be achieved through recognition and reflection upon the values of citizens. Collaborative governance consisting of citizens is crucial for successful SWM. Collaborative governance definitely requires an active participatory decision-making process that reflects citizens’ preferences. Citizen preference also tends to substantially change with life pattern and life quality. These shifts can be caused by slight variations in both social priorities and personal preferences for SWM. Therefore, collaborative water governance must be frequently renewed in response to citizens’ values through the participatory framework. The An’yang Stream in South Korea is generally regarded as a representative urban stream restoration case that has been successfully led by collaborative governance. By conducting individual surveys with citizens on-site, this study addresses how citizens’ preferences of the stream’s management have changed between 2005 and 2015. In addition, this study used three quantitative hydrologic vulnerability indices: potential flood damage (PFD), potential streamflow depletion (PSD), and potential water quality deterioration (PWQD). They can spatially quantify citizen preference using the Analytic Hierarchy Process (AHP), which can systematically derive citizens’ subjective relative-weighted preferences. In the end, this study identified critical differences in priorities in regard to vulnerable areas between in 2005 and in 2015.

We used ensemble climate change scenarios, a hydrologic model, stream channel survey, a hydraulic model, and a travel forecast model to develop an integrated impact assessment method. High-resolution climate change scenarios are based on the combinations of two emission scenarios and eight general circulation models. The Precipitation-Runoff Modeling System was calibrated and validated for the period 1988-2006, and simulated for determining the probability of floods from 2020-2049. We surveyed stream cross sections at five road crossings for stream channel geometry and determined floodwater surface elevations using the HEC-RAS model. Four of the surveyed bridges and roadways were lower in elevation than the current 100-year floodwater surface elevation, leading to relatively frequent nuisance flooding. These roadway flooding events will become more frequent under some climate change scenarios in the future, but climate change impacts will depend on local geomorphic conditions. While vehicle miles traveled were not significantly affected by road closure, vehicle-hours delay demonstrated a greater impact from road closures, increasing by 10 percent in the Fanno Creek area. Results indicate that any cost analysis is extremely sensitive to the occurrence of human fatalities or injuries and fairly insensitive to delay costs. In addition, this research presents a comprehensive classification of flooding costs, identifies preventative measures, and makes short- and long-term recommendations. Our research demonstrated the usefulness of the integration of top-down and bottom-up approaches in climate change impact assessment, and the need for spatially explicit modeling and participatory planning in flood management and transportation planning under increasing climate uncertainty.

  Citation × Citation Citation Abstract Copy Title: Historical Vegetation of Central Southwest Oregon, Based on GLO Survey Notes : Final Report to USDI Bureau of Land Management, Medford District Author: Hickman, O. Eugene, Christy, John A. Year: 2011 Historical vegetation at the time of European settlement is of great interest to both the public and land managers, but is poorly documented. One source of data are the earliest land survey records of the General Land Office (GLO). Rectangular township surveys in Southwest Oregon were initiated in the mid 1850’s as settlers began to claim homesteads in the Bear Creek Valley surrounding what is now Medford. We examined GLO land survey field notes and plats (maps) accompanying the surveys, transcribed GLO landscape data into an Access database, and classified the data set into very general vegetation types for mapping. About 89 vegetation types (subclasses) were described for mapping historic vegetation, distinguished by major differences in plant composition and topographic features. Tree density was estimated from section line descriptions and witness tree spacing at corners, and was used to classify stands into tree classes. These types then were combined into broad “Vegetation Classes” for mapping (i.e. savanna, shrubland, forest, prairie). Classifying and mapping historical vegetation occurred on about 418,500 acres in an earlier OSU study, and about 720,700 acres in this BLM study, located in Jackson and Josephine Counties. The authors merged results from these adjacent GLO studies, expanding the coverage to approximately 1.14 million acres (49 townships). Modern soil surveys of the study area helped the authors interpret GLO data and draw vegetation boundaries. About 44% of the landscape was closed upland forest, 41% woodland, 1.4% riparian forest, 2% oak or conifer savanna, 1% shrublands, and 11% bottomland meadow or upland prairie. Forest types ranged from moist, mixed conifer uplands to dry valley ponderosa pine-hardwood grassland. Large areas of prairie and mixed oak-conifer woodland dominated many low elevation locations on plains, foothills, and especially clayey terraces or southern slopes near what is now Medford. Nearly 115 plant species or plant groups were identified by the surveyors, mostly trees and shrubs. Some were misidentified and not easily interpreted by the authors when archaic names were used by the surveyors. Grazing quality was frequently noted as surveyors attempted to describe land productivity for livestock. Historic baseline plant data is presented for broad landscape transects and sometimes by topographic positions, but is limited by the sketchy nature of the original surveyor notes. Nearly 350 homestead parcels of various sizes were claimed in the study, as identified in GLO survey notes and on Donation Land Claim maps, showing how quickly settlement occurred in the study area after gold was discovered in 1851. Most early homesteads included prairie or oak savanna, which was open and more easily converted to farmland or pasture. Early saw mills, grist mills, fields, roads, water diversions and major Indian trails were also identified and transcribed from the GLO records.

  Citation × Citation Citation Abstract Copy Title: Introduction to Common Native and Potential Invasive Freshwater Plants in Alaska Author: Morgan, Vanessa Howard, Sytsma, Mark Year: 2009 Freshwater aquatic plants are found in most lakes and rivers in Alaska. They range from tiny floating plants that can form mats on a lake surface to emergent plants growing two meters above the water. Aquatic plants are an important part of freshwater environments. They provide food and shelter for a wide variety of insects, fish, mammals, and birds; stabilize shorelines; and form an important link in nutrient cycles. To date, Alaska has had relatively few problems with invasive, non-native aquatic plants. However, invasive aquatic plants pose an increasing threat to human safety and the integrity of native aquatic communities. Actions taken to detect and prevent the introduction and spread of invasive aquatic plants in Alaska are necessary in order to avoid the environmental and economic harm invasive plants have caused in other parts of the United States. The primary purposes of this manual are to aide the identification of freshwater aquatic plants that are likely to be seen in Alaska’s lakes, streams, bogs and marshes; and to help prevent the spread of harmful invasive plants. This manual was written for people who do not necessarily have a scientific background, but it also should be useful for professionals who need assistance in identifying common aquatic species.

  Citation × Citation Citation Abstract Copy Title: The Impact of Collective Bargaining on the Civil Service Merit System in Oregon Author: Blanchard, David K. Year: 1994 This study examines the impact of collective bargaining on the civil service merit system in the State of Oregon. Four topics of current interest are explored. The first is a discussion of the status of collective bargaining and the civil service merit system legislation. The second topic is an analysis of the extent to which the day-to-day administration of public sector personnel functions is determined by the relative influence of collective bargaining agreements and civil service rules. The third is the impact of the collective bargaining model on the integrity of the merit principle. The final topic addressed by this study is the implication of the relationship between collective bargaining and civil service for the effective administration of public sector personnel systems in the future. This research utilized a multiple methods design. The data collection methodology involved two approaches. The first was a document review of state statutes, administrative rules, Employment Relations Board orders, and court decisions applicable to the civil service and collective bargaining. The second approach to data collection employed a written survey designed to solicit the opinion of personnel administrators and others in a position to have an opinion concerning the influence of collective bargaining within their respective jurisdictions. Both qualitative and quantitative methods of data analysis were employed to interpret the data. Qualitative analysis of historical documents yielded descriptive information pertaining to such factors as the proliferation of collective bargaining legislation and the rationale behind such legislation. Quantitative survey data were summarized through the use of descriptive statistics. In addition, qualitative survey data were analyzed using techniques of narrative description and content analysis, which were applied to the open ended survey responses and interview data. A combination of quantitative and qualitative techniques were used in tandem with the expectation that such an approach would contribute to a more thorough investigation of the research question and lead to a better understanding of the impact which collective bargaining legislation may have had on the civil service merit system than would the use of either technique alone.

  Citation × Citation Citation Abstract Copy Title: Survey of Aquatic Plants in Corps of Engineers Reservoirs Author: Walker, Kimberly D., Sytsma, Mark D. Year: 2000 A survey of aquatic plants in a selected Corps of Engineers reservoirs in Oregon was conducted. Cottage Grove, Dorena, Fern Ridge, Dexter and Willow Creek Reservoirs contained abundant aquatic plants. Potamogeton pectinatus and Potamogeton epihydrous were the most common native plant species. Myriophyllum aquaticum and Potamogeton crispus were the most widespread nonnative plants. Species richness in the reservoirs was correlated with trophic status and basin morphology. Shallow reservoirs that included extensive areas of nutrient-rich sediments that were historic flood plain soils supported the greatest biomass and number of species. Mesotrophic reservoirs had lower species diversity. Oligotrophic reservoirs with steep basin morphology, nutrient-poor sediments, and large water level fluctuation did not support aquatic vascular plant populations. An aquatic plant management program should be developed for the reservoirs. The program should focus on preventing introduction and spread of invasive aquatic plants and on rapid response procedures for new infestations. Those reservoirs that currently support aquatic macrophyte communities may be most susceptible to invasion and rapid spread of new introductions, however, even reservoirs that are currently free of aquatic plants may be invaded. Early detection is critical to effective implementation of rapid response procedures for invasive aquatic plant control. Annual survey of the most productive reservoirs is recommended to document introduction of new species. Plant community composition changes during the growing season, and multiple surveys during the growing season are preferred over one-time visits. Management of established populations of invasive species in the reservoirs will be difficult. Where invasive plant abundance is limited in area and number management activities may be implemented to slow dispersal and perhaps eradicate the plants. Integrated pest management procedures should be followed to ensure effective and economical aquatic plant control.

  Citation × Citation Citation Abstract Copy Title: Oxygen Demand Trends, Land Cover Change, and Water Quality Management for an Urbanizing Oregon Watershed Author: Boeder, Michael Karl Year: 2006 In-stream aquatic habitat depends on adequate levels of dissolved oxygen. Human alteration of the landscape has an extensive influence on the biogeochemical processes that drive oxygen cycling in streams. Historic datasets allow researchers to track trends in chemical parameters concomitant with urbanization, while land cover change analysis allows researchers to identify linkages between water quality trends and landscape change. Using the Seasonal Kendall's test, I examined water quality trends in oxygen demand variables during the mid-1990s to 2003, for twelve sites in the Rock Creek sub-watershed of the Tualatin River, northwest Oregon. Significant trends occurred in each parameter. Dissolved oxygen (DO (%sat)) increased at five sites. Chemical oxygen demand (COD) decreased at seven sites. Total Kjeldahl nitrogen (TKN) decreased at five sites and increased at one site. Ammonium (NH3-N) decreased at one site and increased at one site. Multiple linear regression indicates that nitrogenous oxygen demand accounts for a significant amount of variance in COD at ten of the twelve sites (adjusted R2values from 0.14 to 0.73). Aerial photo interpretation revealed significant land cover change in agricultural land cover (-8% for the entire basin area) and residential land cover (+10% for the entire basin area). Correlation results between seasonal oxygen demand data and land cover values at multiple scales indicated that: (I) forest cover negatively influences COD at the full sub-basin scale and positively influences NH3-N at local scales, (2) residential land cover positively influences DO (%sat) values at local scales, (3) agricultural land cover does not influence oxygen demand at any land cover assessment scale, ( 4) local topography negatively influences TKN and NH3-N, and (5) urban runoff management infrastructure correlates positively with COD. Study results indicate that, with the exception of forested land, local scale land cover and landscape variables dominate influence on oxygen demand in the Rock Creek basin. Since DO conditions have improved in these streams, watershed management efforts should emphasize local influences in order to continue to maintain stream health.

  Citation × Citation Citation Abstract Copy Title: Map-based Probabilistic Infinite Slope Analysis of the Stephens Creek Watershed, Portland, Oregon Author: Cole, Ryan Andrew Year: 2013 The Stephens Creek Watershed in southwest Portland, Oregon was chosen by the city as a pilot project for urban stream restoration efforts, and the infiltration of stormwater was identified as a potential restoration strategy. The Stephens Creek Watershed has historically been known to be unstable during high precipitation events (Burns, 1996), and the need to address the response of slope stability to anthropogenically-driven changing groundwater conditions is the focus of this study. Airborne light detection and ranging (LiDAR) and geotechnical data from the City of Portland were employed to create a high resolution (0.84 m2) physics-based probabilistic slope stability model for this watershed, using the map-based probabilistic infinite slope analysis program PISA-m (Haneberg, 2007). Best and worst case models were run using fully dry and fully saturated soil conditions, respectively. Model results indicate that 96.3% of the watershed area had a probability [less than or equal to] 0.25 that the slope factor of safety (FOS) was [less than or equal to] 1 for fully dry conditions, compared to 76.4% for fully saturated conditions. Areas that had a probability [greater than or equal to] 0.25 that the slope factor of safety (FOS) was [less than or equal to] 1 were found to occur mainly along cut/fill slopes as well as within the deeply incised canyons of Stephens Creek and its tributaries. An infiltration avoidance map was derived to define areas that appear to be unsuitable for infiltration. Based on these results, it is recommended that stormwater continues to be directed to existing sewer infrastructure and that the "storm water disconnect" restoration approach not be used by the city.

  Citation × Citation Citation Abstract Copy Title: Streamflow Modeling of Johnson Creek Subwatersheds Using the Precipitation Runoff Modeling System Author: Malone, Theophilus M Year: 2014 Johnson Creek, in the Portland, Oregon metropolitan region, has several pollutants on the U.S. Environmental Protection Agency’s (EPA) 303(d) list including excess heat, low dissolved oxygen, and harmful bacteria. Understanding streamflow response to precipitation events is an important component to evaluating water quality trends and calculating the Total Maximum Daily Load (TMDL) for pollutants of concern. Investigating the streamflow-precipitation relationship on the subwatershed scale can give insight to the hydrologic response of a given watershed. However, developing rating curves for several subwatersheds can be cost and time prohibitive. The objective of this project was to develop a hydrologic model using the Precipitation Runoff Modeling System (PRMS), developed by the United States Geological Survey (USGS) to validate streamflow estimates for subwatersheds lacking a significant period of record. ESRI’s ArcMap, a geographic information system (GIS), was used to characterize the target drainage basins and extract basin-specific parameters for upper watersheds of Johnson Creek. The Johnson Creek Upper Watershed (JCUW) model was calibrated to an existing streamflow gage at Regner Road, in Gresham, Oregon. Calibrated parameters were substituted into a second PRMS model characterizing the Sunshine Creek Subwatershed, which lies within the JCUW. The Sunshine Creek model was used to validate a flow time-series derived from a pressure transducer and a rating curve.

  Citation × Citation Citation Abstract Copy Title: Tillamook County Waste Disposal Technology Assessment Author: Kumar, Arvind, Menze, Ryan, Smith, Joe, Thomas, Jerrod Year: 2014 Tillamook County is a rural county straddling the Northern Oregon Coast Range with the majority of the local economy based around agriculture, timber, tourism, and fishing. As part of Tillamook County’s mission statement, they strive“to enhance the quality of life for its citizens by promoting and preserving public health and safety, maintaining a stable economy, encouraging wise use of resources, and providing services in the most efficient and cost-effective manner possible.” To that end, Tillamook County, Tillamook County Economic Development Council (TCEDC), Portland State University, Oregon State University, and Tetra Tech have undergone an evaluation and technology assessment process to determine a sustainable, economically-viable, and socially-acceptable pilot installation capable of dealing with the large amount of biodegradable waste produced by the timber and dairy industries. This survey provides a technology assessment and recommendations regarding three potential technologies: thermophilic composting, gasification/pyrolysis, and direct incineration. Each of these technologies have strengths and weaknesses in dealing with the three waste streams (manure, bovine carcasses, and timber slash), and this analysis works as a decision-making guide for choosing the proper technology or array of technologies to dispose of Tillamook County’s biodegradable waste. Title: Tillamook County Waste Disposal Technology Assessment Author: Kumar, Arvind, Menze, Ryan, Smith, Joe, Thomas, Jerrod Year: 2014 Tillamook County is a rural county straddling the Northern Oregon Coast Range with the majority of the local economy based around agriculture, timber, tourism, and fishing. As part of Tillamook County’s mission statement, they strive“to enhance the quality of life for its citizens by promoting and preserving public health and safety, maintaining a stable economy, encouraging wise use of resources, and providing services in the most efficient and cost-effective manner possible.” To that end, Tillamook County, Tillamook County Economic Development Council (TCEDC), Portland State University, Oregon State University, and Tetra Tech have undergone an evaluation and technology assessment process to determine a sustainable, economically-viable, and socially-acceptable pilot installation capable of dealing with the large amount of biodegradable waste produced by the timber and dairy industries. This survey provides a technology assessment and recommendations regarding three potential technologies: thermophilic composting, gasification/pyrolysis, and direct incineration. Each of these technologies have strengths and weaknesses in dealing with the three waste streams (manure, bovine carcasses, and timber slash), and this analysis works as a decision-making guide for choosing the proper technology or array of technologies to dispose of Tillamook County’s biodegradable waste.

  Citation × Citation Citation Abstract Copy Title: Impacts of Early Sexual Experience and Associated Risk of Sexually Transmitted Infection (STI) among Teens and Adults in the United States Author: Garcia-Alexander, Ginny Year: 2008 This analysis explores incidence rates of sexually transmitted infections (STIs) among minority group teenagers (aged 15-19) and adults aged 20-34 in the United States. The primary research question is aimed at whether or not the early onset of sexual activity is directly related to the incidence of STI transmission among Americans. Discussion is given to the current literature with respect to the most recent trends in STIs as well as some historical background on classifications. Also examined are the differing impacts observed for those who are affected by bacterial infections (young minorities) and those who are affected by viral infections (majority group members with higher levels of education). The National Survey of Family Growth, Cycle 6, 2002 was used to obtain descriptive results presented in the form of tabular representations and logistic regressions that model the likelihood of contracting an STI for both teens and adults.

Two contiguous protected areas were recently established that traverse this region via blocks of forest connected by narrow forest corridors: the Masoala National Park, which expands further to the east, and the Makira Protected Area, which expands further to the west and northwest. The two extant ruffed lemurs, Varecia variegata and V. rubra, overlapped in this region historically and, on rare occasions, hybridized. As such, land north of the Bay of Antongil is a critical part of the ruffed lemur's northern geographic range. Habitat surveys and interviews with local informants were carried out in this region to determine the extent of suitable habitat for Varecia populations, to assess the extent of human exploitation of this genus, and to obtain data on the western and northern range limits of V. rubra. Interviews indicated that there are populations of V. rubraas far northwest as the confluence of the Antainambalana and Sahantaha Rivers. Surveys and interviews revealed extensive habitat degradation and lemur hunting in the three major river drainages north of the Bay of Antongil. The recent establishment of protected forest blocks and forest corridors in the region was critical, as these links will provide the only connections between Varecia populations that would otherwise be entirely isolated in forest patches surrounded by agricultural land. The geo-referenced habitat survey and the summary of interview results provided here can be used as comparators for future population and habitat assessments following the establishment of the protected areas. A primary direction for future work should be to examine how Varecia populations are adapting to conditions in and near forest corridors.

Year: 2013 Status symbols, are behaviors that individuals use to communicate their place in society (Goffman, 1950). A commonly noted status symbol is participation in the high arts. A recent study described types of music in categories ranging from high-brow, to middle-brow, and low-brow. It was found that consumers of music, particularly the high-brow, were motivated to attend concerts for reasons relating to social capital (Roose & Stichele, 2010). Arts for All is a program in Portland Oregon that offers access to high art performances by making five dollar tickets available to those who qualify for SNAP (Supplementary Nutrition Assistance Program). The number of tickets purchased through the program is tracked by participating organizations, but little is known about the experiences of those who are accessing Art for All. The mixed method approach of surveying and one-on-one interviewing will be utilized to answer two questions 1) Are individuals receiving SNAP benefits aware of the Arts for All Program and why or why not have they used it? 2) What is the experience of individuals using the Arts for All Program, and what does it mean to them? A survey will ask SNAP recipients about their access to the program, and interviews will provide insight into the identity issues that arise when individuals who are low-income enter a space historically reserved the higher classes.

Migration Patterns of Portland’s Young and College-Educated, 1980-2010 Author: Jurjevich, Jason R., Schrock, Greg Year: 2012 For many metro areas, including Portland, being economically competitive in today’s knowledge and information economy depends on attracting and retaining young, college-­‐educated (YCE) migrants. On this indicator, Portland has been most successful: since 1980, the Portland metropolitan region has attracted college-­‐educated individuals under the age of 40 at some of the country’s highest net migration rates in good economic times and bad. Though not unique to Portland, the resiliency of Portland’s migration streams, even in periods of economic uncertainty, calls attention to an increasingly selective group of YCE migrants who appear to place greater relative value on non-­‐economic factors—from political milieu to access to quality public transportation—compared to employment opportunities. This trend directly challenges a long-­‐established cornerstone of traditional migration theory suggesting that the decision to move is predicated on benefits exceeding costs, and linked to the importance of jobs and economic opportunity as attractive forces for working-­‐age households. Reading between the lines of recent media accounts, and in particular the television show Portlandia, the shift from economic to non-­‐economic factors has been portrayed in a most interesting way: because young migrants to Portland place relatively low value on work and traditional careers, their desire to exchange employment opportunities for quality of life (amenity) factors indeed makes Portland the city “where young people go to retire.” The question is: in the short and long-­‐term, how sustainable is Portland’s trend of attracting and retaining YCE migrants if labor market outcomes continue to remain worse compared to other metro areas? What are the facts? In this paper we draw upon U.S. Census Bureau data from the 2000 Census and more recent American Community Surveys from 2005-­‐2007 and 2008-­‐2010, to compare migration patterns in Portland to the other 50 largest U.S. metros.

  Citation × Citation Citation Abstract Copy Title: The 1972 cigarette tax referendum: a mass communication campaign Author: Danielson, Gwendolyn Moore Year: 1972 During the past forty years, Oregon voters have approved only two tax proposals; both taxes on cigarettes. The subject of this study is the campaign carried out by proponents of H.B. 3064 to pass the most recent Oregon tax referendum measure. Central to the questions asked in the investigation of the 1972 cigarette tax campaign was why the outcome of this proposal was successful. The thesis hypothesizes that the critical variable was the involvement of major socio-economic interest groups in formulating and disseminating persuasive campaign messages. The rationale for entering into such a study was the shortage of information on campaigns which focus not only on the effects of the "new politics" on the electorate, but which fill in details of significance to the historical setting within which the campaign takes place. Further, there is an apparent shortage of information on state-wide referendum campaigns which describe the campaign setting, the structure of the decision-making organization directing the campaign effort, and the voters reaction to campaign strategies. For these reasons two research methods were utilized for the descriptive case study: a field investigation and a two-part opinion survey. The former traced the historical-political situation in Oregon, action taken by the 1971 legislative assembly to correct the state budgetary dilemma, the mobilization of public and private individuals following the successful referral drive to place the cigarette tax on the ballot, and campaign strategies carried out during the 40 day period prior to the special election. By reviewing all available news reports and interviewing those persons active in the campaign, the field investigation revealed that the state was indeed threatened by budgetary crisis and that the proposed tax was the only immediately available solution. An alternative source would have required another special session, another 90 day waiting period, and the threat of another referendum. Without the tax, state agencies depending for support on revenue coming from the General Fund would face a two percent cut in funds for the 1972-73 fiscal year. It was also found in the field investigation that the cigarette tax had support from legislative leaders of both political parties; a collection of large permanent interest groups; and an array of state officials and private citizens with pocket-book interest in passing the ballot measure. Persuasive appeals developed by the involved groups focused on the fiscal impact of a tax defeat on these and other special economic groups in Oregon. Results of the second research method, the voter-leadership survey, indicated that the voters surveyed were generally accurate in assessing the participation of interest groups and were influenced by those groups most visible and state officials most vocal. It also revealed that while the voters professed to being influenced by certain groups or individuals, the reasons they gave for their vote choice were not those emphasized by the influence sources. The leadership survey found that interest group leaders were somewhat more accurate than legislators in ascribing motives to the choices voters made, but that there was a significant discrepancy between opinions of voters and opinions of the state leadership relevant to the reasons people voted as they did. As to the central question of this thesis, the investigation did confirm the proposition that interest groups made the difference in the success of the 1972 cigarette tax measure. Interest groups were effective, chiefly because of the many roles they performed in each phase of the campaign: as initiators of campaign activity, as legitimizers, as fund raisers, and as channel sources for disseminating persuasive messages to both their own members and to the general public. The study strongly suggests that it was the mediating activity of state and local influential, through the mechanisms of special interest pressure and cause groups which provided the critical margin in the vote outcome.

Annual rings from fifteen trees were counted in order to establish age versus trunk diameter ratios. This greatly simplified the dating of trees. Transects were then run through individual groves to determine population age structures. These age structures, along with Q. garryana's distribution patterns, were graphically compared with historic temperature, precipitation, and growing season data. The effect of livestock grazing on oak reproduction was examined. Potential vagility of the species was evaluated by estimating the potential for acorn dispersion by airfall, streams, vertebrates, and the human (aboriginal) population. Finally, pollen evidence was scrutinized in conjunction with acorn dispersal rates in order to determine the longer term history of Q. garryana in this portion cf its range.

Each individual observation consists of one or more sensor measurements, a geographic location, and a time. With billions of historical observations stored in diverse databases and in thousands of datasets, scientists have difficulty finding relevant observations. We present an approach that creates consistent geospatial-temporal metadata from large repositories of diverse data by blending curated and automated extracts. We describe a novel query method over this metadata that returns ranked search results to a query with geospatial and temporal search criteria. Lastly, we present a prototype that demonstrates the utility of these ideas in the context of an ocean and coastal margin observatory.

  Citation × Citation Citation Abstract Copy Title: The fisheries of the Lower Columbia River, 1792 to 1850, based on EuroAmerican explorer and fur company accounts Author: Martin, Michael A. Year: 2006 The role of fish in the Native American economy of the lower Columbia River has never been considered in detail. My study focused on the Columbia River from its mouth to the Cascades and the Willamette River from its confluence with the Columbia to Willamette Falls. For this study I asked: How was salmon used? What other fish were important? Where and how were these fish taken and used? To address these questions, I evaluated historical documents, including explorer's accounts and the administrative records of fur companies dating from the late 1700's through the 1850's. I used fishery data, physical descriptions, migratory and spawning habits, and foraging patterns to identify fish in historic accounts. I annotated historic information and provided a synthesis of the historic fisheries. White sturgeon (Acipenser transmontanus), eulachon (Thaleichthys pacificus) and chinook salmon (Oncorhynchus tshawytscha) dominated the trade. Chum (O.keta) and lamprey (Lampetra sp.) were available, although not traded in large numbers. White sturgeon, eulachon, fall chinook, chum and lamprey were smoke cured. Steel head (0. mykiss) , coho (O.kisutch), perch (Embiotocidae), and resident trout were traded in small numbers indicating that other fish were part of the economy. Sockeye. salmon (O.nerka) was not traded. f "~{.' Indians captured white sturgeon with: multiple hooks on set-lines and funnel nets to take white sturgeon during the winter; scoop nets and the eulachon rake took eulachon; spring and summer chinook were taken with hoop nets and platforms in the Cascades rapids and at Willamette Falls; gaffs were used to take chinook and sturgeon during the summer in Baker Bay; and hoop nets took fall chinook in streams. Seine nets were noted but not were not discussed except for the chinook fishery of Baker Bay. Historic information on fishes used and methods of capture contrasts with the archaeological record of the Portland Basin. Resident freshwater fish, minnows (Cyprinidae) and suckers (Catostomus sp.), are abundant in the archaeological faunal record, but are rarely mentioned in historic accounts. Artifacts such as net weights are common in archaeological contexts in contrast with the limited discussions in the historic record. Possible explanations for these discrepancies are reviewed.

It is not a survey of the responses of all women in the westward movement, but, rather, an exploration of the perspective of those women who left a written record of their perceptions or recollections. The thesis focuses on the diaries and reminiscences of women travelling, primarily but not exclusively, in the years 1851-1853. The introductory material consists of a review of the existing historical literature on women and the West, and a discussion of the methods and assumptions used in the thesis. Following this is a short sketch of the history of the migration to Oregon. The major part of the thesis is organized around five themes which emerge from women’s diaries and reminiscences.

Since 1990, more than 20% of Madagascar’s mangrove ecosystems have been heavily degraded or deforested due primarily to increased harvest for charcoal and timber and the expansion of agriculture and aquaculture. Anthropogenic-driven loss is particularly prominent in the north-western Ambanja and Ambaro Bays (AAB). At over 24,000 ha, AAB is one of Madagascar’s largest mangrove ecosystems, including prominent estuaries fed by rivers and streams originating in the country’s highest mountain range. Similar to the national rate, AAB has experienced approximately 20% loss since 1990, driven primarily by over-harvesting for charcoal and timber. Continued loss threatens the livelihoods and wellbeing of thousands of residents who rely on the many goods and services provided by a healthy, relatively intact mangrove ecosystem. To combat this loss, Blue Ventures (BV), in partnership with local communities and the University of Antananarivo, is working to protect, restore and encourage the sustainable use of mangroves. BVs’ Blue Forests project aims to help maintain and diversify local livelihoods and to sustainably manage mangroves and their associated biodiversity in AAB, as well as throughout western Madagascar. This chapter provides an overview of the biophysical characteristics, historic dynamics and current status of the AAB mangrove ecosystem, and mitigation strategies being implemented through BVs’ Blue Forests project.

Year: 2002 The Bull Run watershed is located 41.8 kilometers east of Portland, Oregon in the Mt. Hood National Forest and consists of two reservoirs supplying drinking water to over 840,000 people in the Portland metropolitan area. In March 1998 Steelhead and Spring Chinook were listed as threatened in the Lower Columbia basin under the Endangered Species Act. Historical reservoir operations during the summer released no water downstream resulting in stream temperatures exceeding the state water quality standard for salmonids. CE-QUAL-W2 Version 3 is a two-dimensional water quality and hydrodynamic model capable of modeling watersheds with interconnected rivers, reservoirs and estuaries. CE-QUAL-W2 Version 3 was used to model temperature in the reservoirs and river to investigate management strategies to meet water demand and fish habitat requirements. Management strategies evaluated included adding selective withdrawal, increasing reservoir size, constructing a new water supply reservoir, and altering selective withdrawal operations from historical patterns.

Year: 2016 Problem, research strategy, and findings: The fate of archaeological sites in cities, towns, and county jurisdictions are greatly affected by the decisions of local governments and planning departments, which usually operate with little formal guidance regarding archaeological site stewardship. What strategies do local governments use to effectively manage archaeological sites in their jurisdictions? Which ones work best? To address these questions, we carried out an exploratory study of mechanisms used by local government planners for archaeological resource protection in 24 states between 2008 and 2015, obtaining information from 69 local governments. We use questionnaires and interviews with local government staff, Tribal Historic Preservation Officers (THPOs), and State Historic Preservation Officers (SHPOs), identifying the range of practices employed. Within the jurisdictions we studied, the most elaborate programs a) have local ordinances protecting archaeology, on-staff archaeologists, and use special archaeological districts and zoning overlays, survey, and development guidelines linked to archaeological site probability models; b) maintain cost-saving partnerships with SHPOs, THPOs, universities, and local nonprofit heritage organizations; c) or use a combination of these practices.

  Citation × Citation Citation Abstract Copy Title: Welfare stigmatization and the elderly: the case of the Supplemental Security Income program Author: Man, Peter Jic-Leung Year: 1979 Policy-makers and others historically have assumed that welfare programs should give assistance to the poor and carry stigma. This attitude in part developed from the English Poor Laws tradition in which poverty was considered a negative condition. Labeling theory has often been used to explain the process of welfare stigmatization. Once an individual is labeled as a deviant, such as a welfare recipient, a self-fulfilling prophecy is initiated. Others perceive and respond to the individual as a deviant and the individual also internalized the stigma attached to such a role. The stigma attached to public dependency becomes an outcome of this labeling process. This study identifies the relationship between welfare stigma and the elderly and has three objectives. First, it challenges the usefulness of labeling theory in explaining the perception of welfare stigma among elderly recipients. Second, it analyzes why different levels of stigma are attached to different public assistance programs. Third, it examines why some recipients feel more stigmatized than others. Historically, the elderly poor have heen identified as the deserving poor and provided for under most social programs. Because of differential treatment between the elderly poor and the able-bodied poor, this study contends that these groups develop different self-images as welfare recipients. A single welfare image applied indiscriminately to both groups results in a poor fit. Instead of internalizing the negative image from the outside community, the elderly may have internalized the deserving poor image and subsequently perceive their welfare status as less stigmatized. Congress established the Supplemental Security Income (SSI) program in 1972 to replace the state-run Old Age Assistance (OAA) program. By placing SSI under the Social Security Administration, this new program seeks to provide additional income with less stigma to the aged poor. Data for this study come from two separate surveys: a local survey of 400 respondents and a national survey of 8600 respondents. The most important dependent variable in this study is welfare stigma. It is operationally defined by three indicators: 1) whether recipients feel bothered in receiving assistance; 2) whether recipients feel embarrassed to admit their welfare status; and 3) whether recipients perceive community disrespect for thier welfare status. Factor analysis enabled a welfare stigma index to be constructed using the above three items. The often cited welfare stigma was not substantiated by the data. Elderly recipients of both OOA and SSI had low stigma feelings. Labeling theory, while useful in explaining welfare stigma of other poor subgroups, is not applicable to the elderly. Significantly less stigma was found to be associated with SSI than with OAA. Other findings supporting the SSI program include: more recipients had confidence in the Social Security Administration than in local welfare agencies; more were satisfied with the performance of SSI than with OAA; more non-recipients expressed a willingness to use SSI. In contrast to findings of many studies, this study found that some demographic variables, such as education and socioeconomic status, were significantly related to stigma. This study has theoretical and practical significance. First, it demonstrates that labeling theory is not useful in explaining stigma perception of the elderly. Second, it provides important baseline data to judge future performance of SSI and other similar programs. The analysis calls for the need to design effective social programs on a universalistic rather than class-specific basis. Options for change in the income-maintenance programs in the 1980's are discussed and include an analysis of the two-tier proposal.

  Citation × Citation Citation Abstract Copy Title: An Assessment of the Impact of Public Housing on the Low Income Elderly Residents of the Burnside Community Author: Jacobs, Timothy C. Year: 1977 This study will be a look at housing for Portland's Burnside population with special emphasis on the Foster hotel public housing project. Before housing or any other aspect of Burnside can be intelligently discussed, it is important to have a realistic historical and contemporary understanding of the Burnside community. The second chapter of this study is designed to provide that understanding. The third chapter surveys the ways that other American cities have dealt with their skid row communities. Cities roughly the same size as Portland were chosen. Their efforts will be compared to Portland's plans for and actions toward its Burnside area -- the subject of Chapter IV. In this chapter, a critical analysis of the social policy recommendations made by the Human Resources Bureau for the downtown urban renewal area is offered as this is the official public social policy for the area. The next chapter of this study presents a survey done of the roster hotel to determine whether or not it is meeting the needs of the community. When the roster was initially planned, certain promises were made about who would be housed there and how it would serve Burnside. The questionnaire given to the Foster residents was designed to see if those promises were kept and to gauge the overall satisfaction the residents have with the hotel. It is hoped that with the background material provided in the first chapter of this study, a context will be established within which the reader can understand housing as it relates to this community.

  Citation × Citation Citation Abstract Copy Title: Attitudes of psychiatric nurses and aides at an Oregon state hospital toward homosexuality Author: Andersen, Don Year: 1977 Homosexuality is something which has been a part of almost every society throughout history. In western society this has been a subject of secrecy and taboo. Throughout our history homosexuals have been persecuted and forced to hide their sexual identity. The effects of this on an individual should be something of concern to professionals in the mental health field. While in the past there has been little knowledge of homosexuality, and no self-expression on the part of homosexuals, there has, in recent years, been growing information and expression. The effect of this change on mental health workers is what this paper will examine. An historical survey will present the forces which shaped the current attitude of the mental health profession about homosexuality. I will present a general examination of the social ideology toward homosexuality in western society. I will also review the history of those homosexuals who have banded together for companionship, reform, and protest. This will be a context against which I will examine the attitudes of a specific group of people who care for the mentally ill--nurses and aides at a state mental hospital. The questionnaire I used to examine their attitudes surveys a broad range of possible attitudes about homosexuality. The responses will demonstrate what changes have occurred in society’s attitudes toward homosexuality. It will show, specifically, what the attitudes are of those who care for economically disadvantaged, severely disturbed homosexuals.

  Citation × Citation Citation Abstract Copy Title: The sasswood ordeal of the west Atlantic tribes of Sierra Leone and Liberia: an ethnohistoriographic survey Author: Davies, Sarah Louise Year: 1973 The sasswood ordeal of poison presents a divinatory ritual which has been used in criminal cases by the traditional African of Sierra Leone and Liberia. For at least six hundred years, the peoples of these present countries have imposed this strictest of ordeals on their moral transgressors; and the practice has survived, despite the protestations of nineteenth-century missionaries and the encroachment of the western world. The investigation of the historical evidence of the sasswood ordeal among the West Atlantic tribes of Africa has three basic purposes. First, because of the paucity of interpretive data on the sasswood ordeal, the primary purpose of the thesis has been to more clearly delineate the meaning, characteristics, and functions of this poison ordeal as well as the swearing of oaths among the peoples of Sierra Leone and Liberia by amalgamating historical and more contemporaneous evidence. To this end, the distribution of the ordeal was considered; and descriptions were made of the various characteristics of the trait--complex--the poison’s action, the ritual and ceremonial aspects, the sasswood specialist, the accusations made in connection with the ordeal as well as indigenous myths of origin of the ordeal. Intracultural correlations were then presented to demonstrate the interdigitation of the elements in a culture in relation to the ordeal. Finally, some functions, other than the obvious guilt-determining aspect, were presented to demonstrate the various ways in which it had been used historically. A second purpose of this thesis was to demonstrate the intrinsically conservative: qualities of the ordeal as an aspect of religion and law. By assessing the impact of specific historical influences in the region of the West Atlantic tribes, such as Islam, colonialism, slavery, and urbanization, it was shown that no significant change had been witnessed through the six-hundred-year period of the historical record. In concluding this aspect, it was noted that certain "weaknesses" in the historical record—such as its being "piecemeal" and recorded only infrequently--caused problems in interpreting what appeared to be an intrinsically conservative nature of the sasswood ordeal. A third purpose, related to the second, was the application and assessment of "ethnohistoriographic" techniques, that is, those specific methods of historical scholarship utilized by the ethnographer in investigating past cultures. The limits of the use of the ethnohistoriographic techniques included observational bias (which was readily accountable, dealing as it did with hyperbole), the preoccupation with "sensational" data (which provided disparities, over-emphases in the historical record), as well as political motivations such that national prejudice frequently determined the "interpretation" placed on the ordeal. In addition, it was noted that because the sasswood ordeal may be classified as "esoterica," the record for this practice was generally spotty; and this fact affected interpretations on the actual change manifested in the trait complex. The main contribution made by this study has been to afford future readers with a composite and relatively complete source of information on one specific type of poison ordeal practiced among the West Atlantic tribes of Sierra Leone and Liberia.

  Citation × Citation Citation Abstract Copy Title: Calculating the Volume of the May 18, 1980 Eruption of Mount St. Helens Author: Wickham, Dâvid Nuñez Year: 2009 The May 18, 1980 eruption of Mount St. Helens created a massive amount of sediment and debris, thought to be as much as 5.5 billion cubic yards. This sediment causes infill of river stretches and collects along levees protecting southwest Washington State. The sediment must be removed to ensure these areas do not flood. The US Army Corps of Engineers (USACOE) is tasked with flood protection for southwest Washington State and the levees protecting the cities of Castle Rock, Lexington, Kelso, and Longview. The Sediment Retention Dam, opened in 1989 is able to filter out larger particulate but fine grain sediment remains in the water column and is transported further down the river. In order to calculate how much sediment remains to be removed Portland State University’s Environmental Sciences and Management program and the USACOE formed a partnership and generated Digital Elevation Models (DEM) from topographic maps made by the United States Geological Survey (USGS). This was accomplished by taking 600 dots per inch (dpi) scanned images of the eruption path, geographically rectifying them in ESRI’s ArcMap software environment, and running Iterative Self-Organizing Data Analysis Technique (ISODATA) Unsupervised Classification utilizing ERDAS Imagine 9.3 software. After the contour lines were extracted from the images we cleaned up the lines in a raster environment, converted the raster to vector lines, and entered elevations. From these contour lines we created the DEM and calculated the volume difference between the pre-eruption 15 minute USGS maps and the 7.5 minute post-eruption quad maps. The volume difference was 7,870,546,345 m3 for Mount St. Helens quads, - 4,335,917,517 m3 for Spirit Lake quads, -220,149,557 m3 for Goat Mtn. in Cougar quads, -3,155,437,891 m3 for Elk Rock quads, and 734,102,545 m3 for Hoffstadt Mtn. in Elk Rock pre quad. These figures indicated a large generation of sediment and debris on the slope north of Mount St. Helens, sediment deposition in the Hoffstadt Mtn. river reach, and erosion in all other areas. The USACOE will use my raw data contour elevation lines to create their own DEMs incorporating stream locations to further refine the data. From this data they hope to extrapolate how much sediment is left and where the sediment deposits are likely to erode from in the future.

It illustrates the addressable market in the United States, latent customer needs within that market, a viable technical solution to those needs, and an economic modeling of the business possibility. The plan generation process used a deductive approach of to determine the addressable market size. The addressable market was appropriately segmented and a competitive gap analysis was performed. A survey was produced and applied during an on the street interviews with our target market. Needs were grouped and processed through the hierarchical decision making method to extract priority and consistency in the information. The prioritized needs were grouped and considered by contrasting existing solutions in the market. A pricing model emerged indicating multiple revenue stream opportunities. A requirements technical correlation method was applied to derive the overall picture of requirement fulfillment, complexity of solution and overall market position of the proposed product. Technical architecture documents were produced taking into account non-feature issues such as scalability, security and platform independence. Implementation and operation costs were extracted from the complexity models. A cost/revenue model was built using the most conservative minimum attractive rate of return. Determining risks and possible mitigation strategies are also presented. Research for software services in the recreational sports management market indicates a high degree of fragmentation. The large size of addressable market (15mil) along with high fragmentation creates a significant business opportunity technically well executed, smarty positioned product and using a unique profit-sharing pricing model. The project team is encouraged by the opportunity from a well-defined but poorly addressed market. The target rich environment allow us define initial market beach head and to respond as necessary with follow up products. The solution space is clearly understood by the team and tangible product benefits have been identified. There is risk in not testing some of the team’s assumption and product development execution.

This study uses a two-dimensional hydro-morphodynamic model for predicting flow and suspended-sediment dynamics in the downstream of Johnson Creek, the East Lents reach, where the bank of the river has been reconfigured to reconnect to a restored floodplain on a 0.26 km2 (26-ha) site. The simulation scenarios include 10-, 50-, 100- and 500-year event-based deposition modelling of flood events and long-term modelling using the 64 historical flood events between 1941 and 2014. Simulation results showed that the restored floodplain significantly attenuates the upstream flood peak by up to 25% at the downstream. Results also indicated that approximately 20%–30% of sediment from the upstream is deposited on the East Lents floodplain. Furthermore, deposited sediment over the simulated period (1941–2014) is approximately 0.1% of the basin's flood storage capacity; however, the reduction in the storage does not offset the overall flood resilience impact of the flood basin. The sediment conservation at the East Lents flood basin as predicted by the model reduces the annual sediment loading of the Johnson Creek by 1% at the confluence with Willamette River, providing both improved water quality and flood resilience further downstream.

  Citation × Citation Citation Abstract Copy Title: Event Detection Using Correlation within Arrays of Streaming PMU Data Author: Landford, Jordan Year: 2016 This thesis provides a synchrophasor data analysis methodology that leverages both statistical correlation techniques and a statistical distribution in order to identify data inconsistencies, as well as power system contingencies. This research utilizes archived Phasor Measurement Unit (PMU) data obtained from the Bonneville Power Administration in order to show that this methodology is not only feasible, but extremely useful for power systems monitoring, decision support, and planning purposes. By analyzing positive sequence voltage angles between a pair of PMUs at two different substation locations, an historic record of correlation is established. From this record, a Rayleigh distribution of correlation coefficients is calculated. The statistical parameters of this Rayleigh distribution are used to infer occurrences of power system and data events. To monitor an entire system, a simple solution would be observing each of these parameters for every PMU combination. One issue with this approach is that correlation of some PMU pairs may be redundant or yield little value to monitoring capabilities. Additionally, this approach quickly encounters scalability issues as each additional PMU adds considerably to computation - for example, if the system contains n PMUs the amount of computations will be n(n-1)/2. System-wide monitoring of these parameters in this fashion is cumbersome and inefficient. To address these issues, an alternative scheme is proposed which involves monitoring only a subset of PMUs characterized by electrically coupled zones, or clusters, of PMUs. These clusters include both electrically-distant and electrically-near PMU sites. When monitored over an event, these yield statistical parameters sufficient for detecting event occurrences. This clustering scheme can be utilized to significantly decrease computation time and allocation of resources while maintaining optimal system observability. Results from the statistical methods are presented for a select few case studies for both data and power system event detection. In addition, determination of cluster size and content is discussed in detail. Lastly, the viability of monitoring pertinent statistical parameters over various clustering schemes is demonstrated.

  Citation × Citation Citation Abstract Copy Title: Algeria in Perspective: Changing the Understanding of the Modern Algerian State Author: Averett, Austin Year: 2015 Much of the existing literature on the modern state of Algeria reinforces rivalry-based understandings of the politico-linguistic infrastructure that overemphasize the presence of a dichotomy (French v. Arabic) in the linguistic make up of the state. Many studies rely on this construction of an Algerian language dichotomy to predict the future of the state, while; in fact, more attention should be paid to the multilingual, multicultural, and multinational reality of the larger demographic. Algeria’s history of language rationalization has laid the foundation for unique institutional reflections of state power dynamics within a multilingual environment. Discussions of Algeria’s historical background, identity construction, revolutionary movements, nationalism, and the future of Algerian governance would benefit from a more comprehensive and interdisciplinary exploration of the language attitudes that exist across demographics. This paper explores works by sociolinguists such as Hafid Gafaïti, Wallace Lambert, and Mohamed Benrabah and political scientists such as Lindsay Benstead, Amaney Jamal, and Megan Reif to develop how sociolinguistic survey methodologies such at the Matched Guise technique might be utilized to form a better understanding of Algeria's political prospects.

Examining the Lents International Farmer’s Market is an invaluable opportunity to learn more about consumer shopping behavior and market expectations. This study also seeks to identify vendor opportunities and barriers when establishing themselves as retailers at Lents International Farmer’s Market. From both a business and consumer perspective, it is crucial for the market’s survival to gain a sense what is and is not working. Information obtained through customer surveys and structured vendor interviews could benefit the market and help secure its longevity in the Lents neighborhood. This market could also serve as a model to be replicated in other similar neighborhoods should it remain successful.

  Citation × Citation Citation Abstract Copy Title: Modeling the Distribution of Bobcats and Areas of Reintroduction for Fisher in the Southern Washington Cascades Author: Halsey, Shiloh Michael Year: 2013 The fisher (Martes pennanti) is a medium sized member of the mustelid family that once roamed the forests of Washington and whose historic range in the western United States once spread throughout the northern Rocky Mountains, the Cascade and Coast Ranges, and the Sierra Nevada (Carroll, Zielinski, and Noss 1999; Powell 1993, Spencer et al. 2011). Due to pressures from trapping and habitat fragmentation, the abundance of the species in the western United States has decreased dramatically and is thought to be limited to several small, isolated populations. In 2008, fishers were reintroduced to the Olympic Peninsula; however, bobcat (Lynx rufus) predation in the first years is thought to have killed off a significant portion of the released fisher hindering their ability to establish a self-sustaining population (Lewis et al. 2011). Other studies in the western United States have shown that bobcats can be a dramatic force on small or isolated fisher populations. The coniferous forest of the southern Washington Cascades is the possible site of a release of currently extirpated fishers. My research examines the distribution of bobcats in the region and explores the implication this and the habitat variables of the area have for a future reintroduction of fisher. The workflow of the research was a stepwise process of: 1) surveying forested areas in the southern Washington Cascades for the presence and absence of bobcat and acquiring previously completed survey data 2) using a classification tree to model the correlation of bobcat presence or absence with forest variables and 3) applying these relationships to spatial analysis the creation of maps showing areas of high ranking fisher habitat. The classification tree modeled the correlation between the forest variables and the results of the surveys, which included 145 bobcat absence observations and 39 presence observations. The model highlighted a 95% probability of absence above 1,303 m in elevation, 73% probability of absence in areas under 1,303 m in elevation and with a tree diameter value under 43.45 cm, 57% probability of absence in areas between 1,070 m and 1,303 m in elevation and with a tree diameter value above 43.45 cm, and an 89% probability of bobcat presence in areas under 1,070 m in elevation with a tree diameter value above 43.45 cm. I applied an upper elevation limit of 1,676 meters as a threshold for suitable habitat and only considered habitat suitable in cells with a tree diameter above 29 cm. The three locations highlighted as the most suitable areas for reintroduction due to a large amount of the highest ranking habitat and the largest aggregations of suitable habitat cells were around the William O. Douglas Wilderness that straddles the border of the Gifford Pinchot National Forest (GPNF) and the Wenatchee National Forest, another location in the Norse Peak Wilderness northeast of Mount Rainier, and a third location in Indian Heaven Wilderness in the southern portion of the GPNF.

  Citation × Citation Citation Abstract Copy Title: A Study of Special Preparation and Training Needs of Middle School Teachers Author: Seger, Marilyn Year: 1995 The concept of middle level schooling has existed in the United States since the early 1900s. During the early 1960s, middle level schools were organized to meet the unique developmental needs of early adolescents. Yet, special training, preparation and/or certification for aspiring teachers who wish to work at this level are not available in the majority of states. Many state licensing agencies provide either elementary or secondary certification, which historically was believed to be adequate for middle level teaching. This study investigates the special preparation and training needs of middle level teachers as perceived by teachers and administrators in a suburban school district which was involved for several years in the implementation of innovative practices for middle schools. Middle level educators in this district had received in-service training and were engaged in considerable discussions on research related to effective middle schools. Thirty teachers and 10 administrators were surveyed about their own levels of preparation and their concepts of the elements of model preparation programs for middle school teachers. In a follow-up interview process, including a sample of the survey respondents, interviewees discussed in-depth their district's middle school programs; the impact of a state grant focusing on middle school organizational and instructional issues; and their perceptions about staff development needs of middle school personnel that were not being addressed. The data obtained through survey responses, interviews, and examination of district documents showed that the majority of the sample personnel received their training in middle school concept areas through formal in-service opportunities and/or on the job experience. Furthermore, a majority of the participants endorsed and expressed a need for the following: a special preparation program for middle school teachers containing field experience at the middle level; training in the unique developmental needs of the early adolescent; and, special training in a variety of instructional strategies. Results also indicated that the sample personnel were not aware of the school district's own studies on middle level schooling and were dissatisfied with the current programs, which they felt had suffered as a result of a lack of effective leadership at the district and building levels.

  Citation × Citation Citation Abstract Copy Title: 2005 Diamond Lake Submersed Aquatic Vegetation Survey Author: Sytsma, Mark D., Pfauth, Mary Year: 2006 Diamond Lake is a large natural lake having a surface area of some 3214 acres (1300.7 hectares) and a maximum depth of 52 feet (15.8 meters). It is located within the Umpqua National Forest in the Southern Cascade Mountains of Oregon, at an elevation of over 5000 feet (>1524 meters). Diamond Lake is a high-use waterbody that supports angling, public campgrounds, recreational boating, swimming, and water skiing. The human activity associated with the lake has been a significant contributor to the economy of southern Oregon since the early part of the twentieth century. Historically Diamond Lake was fishless but since 1910 the lake has been managed as a popular trophy trout fishery. The unauthorized introduction of the tui chub (Gila bicolor) into the lake in the 1930s caused disruption of the food web and a decline in the fishery. In 1954, the Oregon Game Commission constructed a canal near the Lake Creek outlet, lowered the lake level, and treated Diamond Lake with rotenone, to eradicate tui chub. The lake was restocked with trout following the successful rotenone treatment and a fishery was maintained for several decades. In 1992, tui chub were reintroduced, through accidental introduction or intentional illegal stocking, and again caused a decline in the trout fishery. Originally mesotrophic, Diamond Lake Diamond Lake productivity increased over the last century to a eutrophic state, and is currently included on the Oregon Department of Environmental Quality (ODEQ) 303(d) list of water quality limited water bodies for pH and algae. The lake had severe blooms of the cyanobacteria (blue-green algae) Anabaena flos-aquae, which produce neurotoxins, in the summers of 2001, 2002, and 2003. Microcystis aeruginosa, another toxin producing cyanobacterium species, was also present in the 2003 bloom. Diamond Lake was closed to some public uses (wading, swimming, water skiing, and boating) during portions of all three summers due to public health and safety concerns. Algae blooms and declining trout fishery have been attributed to alteration of the food web by the tui chubs. The chubs spawn early and consume the zooplankton in the lake, which reduces grazing pressure on phytoplankton. Since the lake is nitrogen limited, nitrogen-fixing cyanobacteria dominate the phytoplankton community. Therefore, the chubs reduce the quality of the trout fishery by reducing food available for trout and impact water quality by facilitating cyanobacteria blooms, which can be toxic. In response to the impact of the tui chub on Diamond Lake the US Forest Service and Oregon Department of Fish and Wildlife are collaborating in a tui chub eradication effort. The eradication plan includes a 2.4-m (8 ft) drawdown of the lake in the winter and spring of 2006 and a rotenone treatment of remaining lake volume in 2006 to kill any remaining fish. The US Forest Service prepared an EIS for the drawdown and rotenone treatment. Potential impacts of the drawdown on littoral aquatic plant communities were identified in the EIS. The US Forest Service conducted a qualitative survey to develop a species list for the lake. The survey described here provides a quantitative, pretreatment measure of cover and biomass of aquatic plants in Diamond Lake. Follow-up sampling, using similar methods, will permit assessment of changes in the plant community following drawdown and refilling of the lake.

  Citation × Citation Citation Abstract Copy Title: Climate Change, Its Effect on Migration Patterns of the Cackling Goose and White-Fronted Goose in the Willamette Valley, and Implications for Goose Management Author: Warren, Kelly Year: 2010 This thesis considers the question of whether climate change is affecting the migration patterns of geese in the Pacific Flyway, specifically cackling geese (Branta hutchinsii minima) and Pacific white-fronted geese (Anser albifrons frontalis). Ancillary questions that are considered are as follows: • If global warming is affecting these species, what is the nature of the effects? • How are the changes affecting the human environment and what can be done about these effects? In 1994, the majority of the cackler population in the Pacific Flyway began to winter in Oregon’s Willamette Valley rather than in their historical wintering areas in California’s Central Valley. In recent years, the Pacific white-fronted goose has shown a change in behavior similar to that of cacklers just before their major shift. The reasons for this shift have not been clear, though climate change, agricultural shifts, or competition with other species were thought to be possible causes. Analyses of historical breeding and wintering surveys, bird band data, harvest data, agricultural data, and climate and weather data were undertaken in the course of this thesis to see if the cause or causes could be identified. The results showed that climate and weather data, i.e. an increase in average annual temperature coupled with occasional severe winters, most closely correlated with the cacklers’ shift northward. The data comparison revealed that there is a direct relationship between cacklers and a warming shift seen on the wintering grounds. There also was a secondary correlation between the northward shift and recent changes in agricultural crops in the Willamette Valley. Substantially less data are available for white-fronts, and the relationship between their recent migration changes and climate and/or other factors is much less clear. The following recommendations for management and further study are aimed at more completely understanding the scope and causes of migration shifts and formulating well-founded management plans for geese in the Pacific Flyway: • Continue research to determine if climate change is causing changes in goose population numbers and behavior. • Expand breeding ground flight surveys to include cacklers and habitat preference to learn how habitat change on the Y-K Delta is altering cackler behavior and breeding success. • Expand radio transmitter studies and collar programs for cacklers in Oregon and Washington to verify northerly wintering shifts. • Expand collar programs for cacklers wintering in the Willamette Valley to determine if the population is continuing to shift northward. • Expand banding programs for white-fronted geese to gather more data about migration patterns. • Develop models that will allow researchers and managers to correlate migration behavior with various environmental factors including climate change in order to: 1) determine which factors are causing migration changes in specific waterfowl populations and 2) allow managers to make changes to management plans in advance of rapid changes. • Inform the public about how it can assist in collar surveys or volunteer for the U.S. Fish and Wildlife Service (USFWS). This will enable USFWS to have more concrete data and give the public an opportunity gain a greater understanding of geese and goose management. • Expand research on urban cackling geese to determine the nature and scope of their effect on the human environment and to devise management strategies. • Research energetics in migrating geese to determine whether the shift in migration patterns has its basis in climate change. • Increase data exchange and coordination among agencies. • Formulate and implement plans at the city and county levels to manage growing numbers of geese in urban areas. • Recognize and anticipate the possibility that goose populations may move into new wintering areas and formulate plans for management of those species. • Implement low cost techniques, such as more liberal bag limits and seasons, hazing, etc., to assist agricultural landowners in decreasing goose-related crop damage.

  Citation × Citation Citation Abstract Copy Title: Estimation of Historic Flows and Sediment Loads to San Francisco Bay, 1849 – 2011 Author: Moftakhari Rostamkhani, Hamed, Jay, David A., Talke, Stefan A., Schoellhamer, David H. Year: 2015 River flow and sediment transport in estuaries influence morphological development over decadal and century time scales, but hydrological and sedimentological records are typically too short to adequately characterize long-term trends. In this study, we recover archival records and apply a rating curve approach to develop the first instrumental estimates of daily delta inflow and sediment loads to San Francisco Bay (1849 – 1929). The total sediment load is constrained using sedimentation/erosion estimated from bathymetric survey data to produce continuous daily sediment transport estimates from 1849 to 1955, the time period prior to sediment load measurements. We estimate that ~55% (45 – 75%) of the ~1500±400 million tons (Mt) of sediment delivered to the estuary between 1849 and 2011 was the result of anthropogenic alteration in the watershed that increased sediment supply. Also, the seasonal timing of sediment flux events has shifted because significant spring-melt floods have decreased, causing estimated springtime transport (April 1st to June 30th) to decrease from ~25% to ~15% of the annual total. By contrast, wintertime sediment loads (December 1st to March 31st) have increased from ~70% to ~80%. A ~35% reduction of annual flow since the 19th century along with decreased sediment supply has resulted in a ~50% reduction in annual sediment delivery.

Title: Estimation of Historic Flows and Sediment Loads to San Francisco Bay, 1849 – 2011 Author: Moftakhari Rostamkhani, Hamed, Jay, David A., Talke, Stefan A., Schoellhamer, David H. Year: 2015 River flow and sediment transport in estuaries influence morphological development over decadal and century time scales, but hydrological and sedimentological records are typically too short to adequately characterize long-term trends. In this study, we recover archival records and apply a rating curve approach to develop the first instrumental estimates of daily delta inflow and sediment loads to San Francisco Bay (1849 – 1929). The total sediment load is constrained using sedimentation/erosion estimated from bathymetric survey data to produce continuous daily sediment transport estimates from 1849 to 1955, the time period prior to sediment load measurements. We estimate that ~55% (45 – 75%) of the ~1500±400 million tons (Mt) of sediment delivered to the estuary between 1849 and 2011 was the result of anthropogenic alteration in the watershed that increased sediment supply. Also, the seasonal timing of sediment flux events has shifted because significant spring-melt floods have decreased, causing estimated springtime transport (April 1st to June 30th) to decrease from ~25% to ~15% of the annual total. By contrast, wintertime sediment loads (December 1st to March 31st) have increased from ~70% to ~80%. A ~35% reduction of annual flow since the 19th century along with decreased sediment supply has resulted in a ~50% reduction in annual sediment delivery.

  Citation × Citation Citation Abstract Copy Title: Dynamic Model of Nonmedical Opioid Use Trajectories and Potential Policy Interventions Author: Wakeland, Wayne W., Nielsen, Alexandra, Geissert, Peter Year: 2015 Background—Nonmedical use of pharmaceutical opioid analgesics (POA) increased dramatically over the past two decades and remains a major health problem in the United States, contributing to over 16,000 accidental poisoning deaths in 2010. Objectives—Create a systems oriented theory/model to explain the historical behaviors of interest, including the various populations of nonmedical opioid users and accidental overdose mortality within those populations. Use the model to explore policy interventions including tamper resistant drug formulations and strategies for reducing diversion of opioid medicines. Methods—A system dynamics model was constructed to represent the population of people who initiate nonmedical POA usage. The model incorporates use trajectories including development of use disorders, transitions from reliance on informal sharing to paying for drugs, transition from oral administration to tampering to facilitate non-oral routes of administration, and transition to heroin use by some users, as well as movement into and out of the population through quitting and mortality. Empirical support was drawn from national surveys (NSDUH, TEDS, MTF, and ARCOS) and published studies. Results—Model was able to replicate the patterns seen in the historical data for each user population, and the associated overdose deaths. Policy analysis showed that both tamper resistant formulations and interventions to reduce informal sharing could significantly reduce nonmedical user populations and overdose deaths in the long term, but the modeled effect sizes require additional empirical support. Conclusion—Creating a theory/model that can explain system behaviors at a systems level scale is feasible and facilitates thorough evaluation of policy interventions.

Population Research Center Year: 2015 This document is to accompany the coordinated population forecasts and their corresponding reports prepared by the Population Research Center (PRC). Developing long-term coordinated population forecasts for a county and its sub-areas (UGBs and areas outside UGBs are referred to sub-areas in this document), requires these main stages: 1) compiling and evaluating historical and recent data to ascertain demographic characteristics and trends in the study area and to obtain a population base from which the forecasts may be launched; 2) making assumptions about the future and adjusting the data or rates in the forecasting models (calibrating the models) to incorporate predicted rates or trends; and 3) reconciling, or adjusting the forecasts so the sum of the sub-area forecasts is consistent with the forecast for the county total. We first develop population projections and then we make adjustments to these projections in order to produce population forecasts. Population projections are developed by extending historical and current demographic and housing trends into the future. Forecasting population requires that assumptions be made about future population change, and adjusting the projection models to account for circumstances that perhaps skewed past trends or may affect future change. Such circumstances in the past could be a building moratorium or the opening of a new group quarters facility. Events affecting future change would be, for example, planned future housing development that is higher than usual, a foreseen change in an area’s physical ability to accommodate growth (buildable land available is approaching capacity or improvements to infrastructure are underway), anticipated changes in the economy (the location of a new employer or the upswing or downturn of the economy in general), or an expected change in the local population and household composition (age, ethnicity, and average household size).

Year: 1971 The essential objective of this study was to reveal the degree to which one man, Nicholas Muraviev, was instrumental in bringing about Russia's annexation of The Amur basin, as well as the territory that became the Maritime Province of Siberia. Introductory chapters provide: a) a background summary of Muraviev's education and of his career prior to his service in Siberia and b) a brief historical survey of the area in which his achievements raised Russia to the position of a Far Eastern Power. The main body of the study comprises an analytical narrative of Muraviev's activities during the decade that culminated in the Chinese capitulation at Aigun in 1858. Closing chapters explain the factors that turned the newly acquired territories into a burden for the Russian Government until it decided to build the trans-Siberian railway, and set forth some conclusions regarding the historical significance of Muraviev's role as Russia's pro-consul in Eastern Siberia. Extensive use was made of the prime single source of information on Muraviev's life, Ivan Barsukov's Graf N. N. Muraviev-Amurskii, po ego pismam, ofitsialnym dokumentam, razskazam sovremmenikov it pechatnym istochnikam (materialy d1ia biografii). Also of significant assistance was the bibliography contained in J. L. Sullivan's doctoral dissertation, Count N. N. Muraviev-Amurskii, a full-scale biography. Sullivan's dissertation preceded two important works bearing on the Muraviev period in Siberia and drawn on extensively in the present study; R. K. I. Quested's The Expansion of Russia in East Asia, 1858-1860, and P. I. Kabanov's Amurskii Vopross. Among other particularly valuable sources was P. V. Schumacher's long article, K istorii priobretenia Amurai. Snoshenias Kitaem s 1848 po 1860 g.” contained in Russki Arkhiv, which, together with Russkaia Starina and Krasny Arkhiv, also contain numerous other documents, memoirs and contemporary accounts that were consulted. Of signal value, too, among the special studies, surveys and reference works consulted was the introductory chapter of Andrew Malozemoff's " Russian Far Eastern Policy, 1881-1904. A complete selected bibliography is included. The research undertaken for this study has led to the conclusion that had it not been for Muraviev's imagination and ingenuity, his willingness, on occasion, to flout authority and his dedication and extraordinary stamina, the annexation to Eastern Siberia of almost 400,000 square miles of territory might never have taken place. Muraviev was sometimes impatient, perhaps sometimes insufficiently impressed by broader politico-military considerations that dictated what he regarded as an inexcusably over-cautious attitude toward Russo-Chinese relations in St. Petersburg. He also tended to exaggerate the immediate benefits that would accrue to Russia once she acted boldly on the Amur. Yet the salient fact remains that it was the intensity with which he pursued his idee fixe, both with words and actions, the years of his methodical preparation, with minimal support from the Russian Government, that made it possible for that Government to nullify the Treaty of Nerchinsk and to extend the Russian Empire's realms on the Pacific's shores down to the Korean frontier. It took important external factors, such as the Crimean War, and the resulting replacement of Muraviev's nemesis, Nesselrode, and his clique, with more capable and far sighted officials, to bring Muraviev's plans to fruition. But to say this is simply to say that the authorities in St. Petersburg, viewing the confluence of events on the international scene, finally recognized that in Muraviev they had the right man at the right place at the right time.

  Citation × Citation Citation Abstract Copy Title: An Implementation Analysis of the Water Resources Development Act of 1986 Author: Rich, James Joseph Year: 1993 Implementation research, an area once largely ignored in favor of policy design and impact assessment, now constitutes a significant portion of the policy analysis literature. One of the key issues addressed by the theory building portion of that literature is the necessity of precisely identifying implementation variables, conditions, or actions that measurably contribute to the success or failure of implementation efforts over a broad range of policies and programs, and to then suggest some order of significance. In order to test the validity of a variable set proposed by the literature, a multivariate implementation model was employed as the basis of a case study designed to conduct both a process and impact analysis of the implementation of the Water Resources Development Act of 1986 (WRDA 86). Implementation of the WRDA 86 was selected for this research as it offered an opportunity to investigate implementation of a significant policy change in an established policy arena , the water resource development industry. Following ten years of failure to achieve agreement on an omnibus water resource appropriation, passage of the WRDA 86 was widely perceived to have signaled a new era of water resource development for the nation. It will likely be a period characterized by the transfer of the financial burden of planning, construction, and maintenance of water resource projects from the Federal government to the non-Federal sponsor/beneficiary. The transfer will be achieved by application of cost-sharing formulas contained in WRDA 86 and affirmed in subsequent biannual omnibus water resource development legislation. Cost-sharing and similar beneficiary-pay principles had long been considered as an efficient alternative to water resource programs which relied principally on Federal funding owing to the long held assumption that the benefit from such projects were so "widespread and general" as to be in the national interest. Incorporation of cost-sharing principles in water resource legislation ensured that appropriation language would require local project beneficiaries to assume a larger portion of project costs. In addition to the assumption that application of the principles would lead to economically efficient projects it was also argued that cost-sharing and increased local sponsor input would lead to smaller projects that better reflected local need, projects with greater emphasis on environmental concerns, and the construction of projects in stages or phases. The research proceeded with an implementation process analysis to test the model ’s assumption that specific variables or conditions may be identified as having the greatest significance in the achievement of successful implementation. Furthermore, the study attempted to determine whether identified groups at different "levels" of the implementation hierarchy would rank specified variables consistently or result in a finding that variable criticality rankings tend to reflect one’s position within the hierarchy. Study outcomes did not confirm the model’s assertion with respect to which variables were most critical. This finding may have reflected the fact that conditions thought to be most critical by the model, clear legal directives and legislation that reflects sound theory, were largely issues that had been thoroughly discussed and resolved prior to enactment of the legislation. Position within the hierarchy appeared to influence the rater’s assignment of variable criticality though not to a statistically significant degree. The differences, however, were intuitively consistent and their basis supported by secondary survey data. This finding suggests that future implementation studies need to carefully examine the role of hierarchical position and intergovernmental interdependencies in theory development. With respect to the impact analysis, it was determined that cost sharing would have a demonstrable impact on resulting projects in a variety of areas. Future cost-shared water resource development projects will likely be smaller on average than past projects though the precise impact of cost-sharing is indeterminable. Projects may result in less impact on the environment but largely as a result of reduced size rather than the additional environmental input of local sponsors. Phased and staged construction of large projects will be more likely, particularly where project benefits and revenue streams may be partially captured by incremental construction.

Today, millions of people are afflicted by malaria each year, and hundreds of thousands die. Historically, the most successful synthetic antimalarial drug was chloroquine, as it was safe, inexpensive, and highly efficacious. However, plasmodial resistance to chloroquine now greatly limits its utility. Previously in our laboratories it has been shown that attachment of a "reversal agent moiety" to the side chain of chloroquine can result in the restoration of activity against chloroquine-resistant strains of P. falciparum malaria. In the first part of the work presented here, a study has been made of the importance of the quinoline ring substitution pattern to the activity of such reversed chloroquines. The compounds presented here include those bearing a substituent in the 2-, 5, 6-, 7-, and/or 8- position, and include those with chloro, bromo, iodo, fluoro, nitro, trifluoromethyl, methyl, and methoxy substituents. For reversed chloroquines, 2-, 5-, and 8- substituents have been found to decrease in vitro antiplasmodial activity against P. falciparum relative to 7-chloro substitution, whereas 6- and 7- substituted compounds with various substituents have in many cases similar activity to that of 7-chloro substituted compounds. Little difference has been observed between 6- and 7- substitution, or between chlorine and a methyl group in position 6. In most cases these effects on activity are directionally similar to those observed for chloroquine analogs without an attached reversal agent, but the magnitude of the effect is generally smaller, suggesting that the activities of reversed chloroquines are less affected by modifications to the quinoline ring system than is true for chloroquine analogs without an attached reversal agent. The second portion of this work presents an asymmetrical bis-quinoline (PL241) that is highly active against P. falciparum malaria, with an IC50 of less than 0.1 nM for all strains tested. Mechanistic studies have been performed in which the substitution patterns of the two quinoline rings of PL241 are modified in ways that indicate that either ring system is equally capable of participating in the antimalarial activity of these compounds. The excellent in vitro antiplasmodial activity of PL241 makes this a compound of great interest for further development as a potential antimalarial drug. In the third part of this work, a survey has been made of antimalarial treatments recommended in the European medical literature from the time of Pliny the Elder (active in the first century A.D.) through the advent of modern malaria chemotherapy in the early twentieth century. In the fifteen primary sources utilized in this study, 251 distinct substances - primarily plants - were identified as having likely been used in the treatment of malaria. Of the 38 substances that were described in three or more sources, at least fifteen have been examined by other workers for antiplasmodial activity; in many cases, they were found to have antiplasmodial activity in vitro or in vivo. However, the majority of the phytotherapies for malaria identified in this project have not yet been tested against Plasmodium species, and may provide valuable leads in the search for new compounds active against drug-resistant malaria.

  Citation × Citation Citation Abstract Copy Title: The role of the family in delinquency causation: an interactional view Author: Burfeind, James W. Year: 1984 American society traditionally has held the family responsible for the socialization and social control of children, and when youngsters get into trouble the causal finger of blame is pointed at the family. No wonder then that a recurrent issue within the study of delinquent behavior has been the precise etiological role of the family. This thesis begins with an historical examination of the different approaches taken in the sociological study of delinquency and the family. This research investigated whether "interactive effects" are important in conceptualizing and understanding the family's etiological role. The concept of interaction is based upon the assumption that variables may not have causal efficacy within themselves, entirely independent of other variables. Variable interaction occurs when the effect of an independent variable varies depending on the value of another independent variable. This study utilized questionnaire data gathered as a part of the Richmond Youth Study by the Survey Research Center (University of California, Berkeley) in 1965. The original stratified random sample consisted of 5,545 junior and senior high school students. While this sample included both male and female, black and nonblack adolescents, the present analysis focused on the 1,588 nonblack subsample. Survey data was available on a wide variety of youth-related issues, including self-reported delinquent activity and family conditions. This study analyzed the interactive effects of five family dimensions in relation to four other causal variables commonly associated with delinquency involvement: community social disorganization delinquent friends, attachment to peers, and delinquent definitions. Analysis of variance, a multivariate statistical model, was used to distinguish significant independent and interactive effects. Identified interactive effects were then examined through tabular analysis in order to provide a more precise understanding of how these variables interact in affecting delinquency involvement. Finally, the general notions of variable interaction which are implied by existing theories were assessed. The data analysis revealed that family factors influenced delinquency in different ways. The level of an adolescent's attachment to father was found to be independently related to delinquent activity after controlling for all other effects (independent and interactive). Paternal discipline had an interactive effect on delinquency such that the type of paternal discipline influenced the effect that community social disorganization and number of delinquent friends had on delinquency; in turn, paternal discipline was significantly related to delinquency involvement under certain conditions of these same variables. The other three family factors, however, did not have a significant independent or interactive effect on delinquency involvement. These findings suggest that causal explanation and research dealing solely with direct, independent effects may minimize and oversimplify the causal role of certain family factors. At least a small portion of the family's influence on delinquency involvement is through interactive effects with non-familial variables. Existing theories have failed to actively consider such interactive effects. Furthermore, the general notions of variable interaction which are implied by current theories failed to find support in the data of the present study. Thus, future theory and research would likely benefit from consideration of interactive effects.

No wonder then that a recurrent issue within the study of delinquent behavior has been the precise etiological role of the family. This thesis begins with an historical examination of the different approaches taken in the sociological study of delinquency and the family. This research investigated whether "interactive effects" are important in conceptualizing and understanding the family's etiological role. The concept of interaction is based upon the assumption that variables may not have causal efficacy within themselves, entirely independent of other variables. Variable interaction occurs when the effect of an independent variable varies depending on the value of another independent variable. This study utilized questionnaire data gathered as a part of the Richmond Youth Study by the Survey Research Center (University of California, Berkeley) in 1965. The original stratified random sample consisted of 5,545 junior and senior high school students. While this sample included both male and female, black and nonblack adolescents, the present analysis focused on the 1,588 nonblack subsample. Survey data was available on a wide variety of youth-related issues, including self-reported delinquent activity and family conditions. This study analyzed the interactive effects of five family dimensions in relation to four other causal variables commonly associated with delinquency involvement: community social disorganization delinquent friends, attachment to peers, and delinquent definitions. Analysis of variance, a multivariate statistical model, was used to distinguish significant independent and interactive effects. Identified interactive effects were then examined through tabular analysis in order to provide a more precise understanding of how these variables interact in affecting delinquency involvement. Finally, the general notions of variable interaction which are implied by existing theories were assessed. The data analysis revealed that family factors influenced delinquency in different ways. The level of an adolescent's attachment to father was found to be independently related to delinquent activity after controlling for all other effects (independent and interactive). Paternal discipline had an interactive effect on delinquency such that the type of paternal discipline influenced the effect that community social disorganization and number of delinquent friends had on delinquency; in turn, paternal discipline was significantly related to delinquency involvement under certain conditions of these same variables. The other three family factors, however, did not have a significant independent or interactive effect on delinquency involvement. These findings suggest that causal explanation and research dealing solely with direct, independent effects may minimize and oversimplify the causal role of certain family factors. At least a small portion of the family's influence on delinquency involvement is through interactive effects with non-familial variables. Existing theories have failed to actively consider such interactive effects. Furthermore, the general notions of variable interaction which are implied by current theories failed to find support in the data of the present study. Thus, future theory and research would likely benefit from consideration of interactive effects. Close

  Citation × Citation Citation Abstract Copy Title: Moving toward integration: a study of theory and practice in feminist therapy Author: Thomas, Susan Amelia Year: 1975 This thesis describes a study designed to explore the emerging field of feminist therapy. The goal was not to test the validity of feminist therapy, to probe the assumptions on which it is based, or to compare it to other forms of therapy but to characterize the theory and practice of feminist therapy as it now exists. Feminist therapy was seen as growing out of the cultural and historical context of the feminist movement, which includes a critique of society with emphasis on the particular psychological consequences for women, and a critique of psychotherapy, particularly Freudian psychotherapy, as oppressive to women and adhering to a double standard of mental health. The field of mental health responded to these criticisms, and feminism simultaneously began a search for alternatives to therapy, Out of both developed feminist therapy. The literature, both in the field and in the alternative press, was reviewed to present a picture of the development of feminist therapy and to highlight issues to pursue in the research itself. Following this review, a study was undertaken of feminist therapists in three metropolitan areas on the West Coast--Portland, Seattle, and the Bay Area--utilizing a qualitative methodology to gather descriptive data and potential patterns for analysis. A natural network approach was utilized to generate the population, following much the same process a woman would go through in locating a feminist therapist. Potential feminist therapists were surveyed via a questionnaire. Self-identification as a feminist therapist was the primary criteria for inclusion in the sample frame. A random sample of 20 percent of the sample frame (20 feminist therapists) was interviewed, and the results transcribed and thematically analyzed to answer five questions: 1) Who are the feminist therapists? 2) How do feminist therapists define feminism? 3) What is feminist therapy? 4) How does feminist therapy perceive and incorporate therapeutic issues? 5) How does feminist therapy perceive and incorporate feminist issues?
