  Citation × Citation Citation Abstract Copy Title: Resident Perceptions of Natural Resources between Cities and across Scales in the Pacific Northwest Author: Morzillo, Anita T., Kreakie, Betty J., Netusil, Noelwah R., Yeakley, J. Alan Year: 2016 As the global population becomes increasingly urban, research is needed to explore how local culture, land use, and policy will influence urban natural resource management. We used a broad-scale comparative approach and survey of residents within the Portland (Oregon)-Vancouver (Washington) metropolitan areas, USA, two states with similar geographical and ecological characteristics, but different approaches to land-use planning, to explore resident perceptions about natural resources at three scales of analysis: property level (“at or near my house”), neighborhood (“within a 20-minute walk from my house”), and metro level (“across the metro area”). At the metro-level scale, nonmetric multidimensional scaling revealed that the two cities were quite similar. However, affinity for particular landscape characteristics existed within each city with the greatest difference generally at the property-level scale. Portland respondents expressed affinity for large mature trees, tree-lined streets, public transportation, and proximity to stores and services. Vancouver respondents expressed affinity for plentiful accessible parking. We suggest three explanations that likely are not mutually exclusive. First, respondents are segmented based on preferences for particular amenities, such as convenience versus commuter needs. Second, historical land-use and tax policy legacies may influence individual decisions. Third, more environmentally attuned worldviews may influence an individual’s desire to produce environmentally friendly outcomes. Our findings highlight the importance of acknowledging variations in residents’ affinities for landscape characteristics across different scales and locations because these differences may influence future land-use policies about urban natural resources.

In this paper, we draw on survey responses collected from more than 250 UA organizations and businesses from 84 cities across the United States and Canada. Synthesizing the results of our quantitative analysis of responses (including principal components analysis), qualitative analysis of textual data excerpted from open-ended responses, and a review of existing literature, we describe six motivational frames that appear to guide organizations and businesses in their UA practice: Entrepreneurial, Sustainable Development, Educational, Eco-Centric, DIY Secessionist, and Radical. Identifying how practitioners stack functions and frame their work is a first step in helping to differentiate the diverse and often contradictory efforts transforming urban food environments. We demonstrate that a wide range of objectives impact how urban agriculturalists practice UA and that political orientations and discourses differ across geographies, organizational type and size, and funding regime. These six paradigms provide a basic framework for understanding UA that can guide more in-depth studies of the gap between intentions and outcomes, while helping link historically and geographically specific insights to wider social and political economic processes.

  Citation × Citation Citation Abstract Copy Title: South Korean Teachers' Beliefs about Diversity: the Impact on Practice of Multicultural Education Author: Yeo, Marie Year: 2016 Teachers in South Korean schools have begun to pay attention to the importance of multicultural education as Korea transforms into a multicultural society from a historically mono culture society. Because of Koreans' pride in the homogeneity of their race, language, and culture, multiculturalism is an idea that is hard for many to accept. Education needs to play a key role in fostering and retaining the value of diversity. Studies suggest that teachers' positive beliefs about diversity play a significant role to develop their multicultural competence and eventually to practice better multicultural education. The problem is little evidence exists in the literature about Korean teachers' beliefs about diversity. The purpose of this study was to examine South Korean teachers' beliefs about diversity, the factors that influence those beliefs, and the impact of those beliefs on their practice of multicultural education teaching. I used a mixed methods research approach which included surveys among a group of elementary teachers in South Korea and interviews with six teachers to examine their beliefs about diversity in more depth. Results indicated that for teachers in this study: (a) intercultural experiences positively influenced Korean teachers' beliefs about diversity; and (b) teachers' beliefs about diversity had a significant impact on their practice of multicultural teaching. Based on the findings, I suggest that teacher education programs provide meaningful intercultural experiences and support teachers to develop positive beliefs about diversity, and eventually, to practice better multicultural education in South Korea.

  Citation × Citation Citation Abstract Copy Title: Building a More Diverse Skilled Workforce in the Highway Trades: Are Oregon’s Current Efforts Working? Author: Burd-Sharps, Sarah, Lewis, Kristen, Kelly, Maura Year: 2014 Jobs in the highway construction trades have historically been primarily held by white men and largely remain so today; of those completing apprenticeships in the highway trades in Oregon between 2011 and early 2014, 83.4 percent were white men. Building a more diverse skilled workforce and making careers in these trades more accessible and appealing to women and people of color has proven challenging. The state’s Bureau of Labor and Industries (BOLI), in collaboration with the Oregon Department of Transportation (ODOT), in 2010 began a statewide effort—the Highway Construction Workforce Development Program—to find, train, and employ a diverse workforce for highway construction jobs throughout the state. The program provides mentoring and four services designed to help workers overcome commonly identified barriers to participation in the heavy highway trades: financial support for childcare; fuel assistance; support for tools, clothes and other required equipment; and overnight travel expenses for jobs. This paper provides the findings of an assessment of these efforts using data on trends in the Oregon heavy highway workforce from the Oregon Apprenticeship System, a phone survey of current and past highway apprentices conducted in early 2014, and a review of the experiences of others states in this area.

  Citation × Citation Citation Abstract Copy Title: Oregon Manufacturing Extension Partnership: Economic Impact Analysis December 2016 Update Author: Nguyen, Hieu, Willingham, Emma, Hulseman, Peter Year: 2016 The Hollings Manufacturing Extension Partnership (MEP), founded in 1988, is a network of non-profit agencies staffed by industry professionals and consultants. Historically, MEP has sought to increase the competitiveness of small to mid-size enterprises (which as a group comprise 99% of all U.S. manufacturing firms) by providing expert guidance and access to resources. In recent years, the severe economic recession sparked increased interest in the strength of the manufacturing sector, due to its longtime status as one of the major drivers of the domestic economy. Oregon Manufacturing Extension Partnership (OMEP), the Oregon branch of MEP, works to provide data-driven analysis and consulting services within the state, improving productivity and competitiveness on both a local and international scale. The Northwest Economic Research Center has provided three previous analyses of OMEP’s contribution to regional manufacturing, using data collected from participating firms to estimate OMEP’s impact on output, employment, and tax revenues. This fourth report carries the analysis forward into 2015. The survey data consists of firm-level estimates of OMEP contributions to sales, employment, investment, and new product development (relative to expected production levels without OMEP). NERC used the industry-standard modelling software package IMPLAN, which produces estimates of the total impact of OMEP across multiple sectors, considering both direct and indirect effects.

  Citation × Citation Citation Abstract Copy Title: Rivers of Steel: The Economic Development of Seattle During the Rail Age, 1870-1920 Author: Loehlein, Neil T. Year: 2014 The Pacific Northwest experienced massive urban development and growth in population from 1870 to 1920. The railroad was a key factor contributing to the influx of people and expansion of the built environment. The rival port towns around the Washington Territory’s Puget Sound all strove to become the dominant center of trade. As the pattern of railroads expanded, this new mode of transportation would have a significant effect on which ports would prosper and which would languish. This paper will show that the rail network that developed between 1873 and 1893 would come to favor Seattle at a critical point in history: just before the Klondike Gold Rush. But as the railroads shaped the development of the Sound, other factors shaped the pattern of the rails as well. Seattle was able to play an early role as a local supply hub because of its early start as a community, central location, and strong maritime trade. The city’s proximity to large and high quality coal deposits also played a role its development and the extension of local rail lines. Seattle’s role as trade hub and local rail network created the infrastructure necessary to convince the Great Northern transcontinental railroad to make the city its terminus, nullifying the competitive advantage of its main rival on the sound, Tacoma. The railroad network that developed during this period further entrenched Seattle’s role as the trading hub of Puget Sound, which played a crucial role in the city’s rise to become the dominant port on the sound. This paper contributes to the historical analysis of Seattle’s early days as a burgeoning port town by surveying the works of scholars and providing a new perspective on the driving forces in Seattle’s rise to economic supremacy.

Data from a 2015 American Community Survey suggests that in the state of Hawaiʻi, 40% of public school 8th graders do not meet the Department of Education (DOE) standards in mathematics. This fall, the National Center for Educational Statistics noted that over half of the country’s public schools reported incidents of criminal activity. As a way to address gaps of learning in the American education system, let us engage in alternative ways by welcoming lessons from the Plant World. Matika Wilbur, of the Swinomish nation in Washington state, and award-winning photographer, teaches us that, “In the beginning, everything had a spirit.” Mayan people come from corn. Hawaiian people come from taro. We are all indigenous to some place and those places have stories of creation and how we came to be. Regardless of your beginning, these are compelling stories that teach us lessons of how we should live and share in the lands we occupy. Historical events and policies fostered by capitalism and colonialism and their consequences have marginalized youth. Metaphysical philosophies from eastern traditions conflict with western methodologies and pedagogy. Plants and their creation stories invite us to be: patient, responsible and respectful and to cultivate collaborative relationships.

  Citation × Citation Citation Abstract Copy Title: Constraining the Holocene Extent of the Northwest Meers Fault, Oklahoma Using High-Resolution Topography and Paleoseismic Trenching Author: Hornsby, Kristofer Tyler Year: 2017 The Meers Fault (Oklahoma) is one of few seismogenic structures with Holocene surface expression in the stable continental region of North America. Only the ~37 km-long southeastern section of the ~55 km long Meers Fault is interpreted to be Holocene-active. The ~17 km-long northwestern section is considered to be Quaternary-active (pre-Holocene); however, its low-relief geomorphic expression and anthropogenic alteration have presented difficulties in evaluating the fault length and style of Holocene deformation. We reevaluate surface expression and earthquake timing of the northwestern portion of the Meers Fault to improve fault characterization, earthquake rupture models, and seismic hazard evaluations based on fault length. We use a combination of airborne lidar (0.5--2 m-resolution), historical aerial photos, and new balloon-based photogrammetric (Structure from Motion) topography (0.25--0.5 m-resolution) collected in this study to analyze and characterize the fault scarp and local fault zone geomorphology. In the northwest, complex surface deformation includes fault splays, a left step, subtle monoclinal warping, and a minor change in fault strike The fault is evident in the landscape as linear escarpments, incised channels on the up-thrown side of the scarp, and closed depressions on the downthrown side. I use topographic profiles, measured perpendicular to the fault scarp to show that the northwest scarp is characterized by decimeter surface offsets. Where the fault traverses the Post Oak Conglomerate the fault zone width rarely exceeds 25 m, in the Hennessey Shale I document an increase in fault zone width with deformation occurring over 20 m to 115 m. I further examined the northwest section of the fault in a paleoseismic excavation where weathered Permian Hennessey Shale and a ~1--2 m-thick veneer of Holocene alluvial deposits have been folded and warped during three surface-folding earthquakes. In an adjacent stream exposure these units are also faulted near the ground surface. Paleoearthquake age modeling (Oxcal) constrained by accelerated mass spectrometry (AMS) dating of detrital charcoal and optically stimulated luminescence (OSL) dating of sandy alluvial beds indicates two earthquakes occurred since ~6152-5550 cal. years BP and one possibly older event along the erosional unconformity along the Hennessey Shale bedrock. This analysis lengthens the Holocene extent of the Meers Fault by ~6 km, to ~43 km, and extends the paleoseismic record of the Meers Fault to ~9598 cal. years BP. These data will improve fault-rupture and earthquake recurrence models used for seismic hazard analysis of the Meers Fault.

LiDAR technology’s use on UAS (Unmanned Aerial System) is a relatively new concept in the rapidly advancing remote sensing & 3D imaging industry. As such, profitability data is either not released by similar business organizations, or there is simply not enough historical data to accurately predict revenue streams with either business model. To assess the feasibility of business models, market research and literature review were performed by our research team. Economic analysis methods were used to determine the most advantageous business plan strategy for the LiDAR business opportunities. Since the success of either business model will rely heavily on the company’s sales ability. Since the focus of this report is on economic analysis to make the best business decision, we have made our valuation calculations based conservative sales forecasts. The startup business plan identifies and critiques two business models identified by the founder entrepreneurs: 1. A service oriented model in which data is collected, processed, and delivered by an operations team to the customer. 2. A product oriented model in which LiDAR UAS is constructed, tested, and sold as a unit that includes training as an entire product for the customer’s own use. Based on these two models, three decision options were evaluated and compared with each other: 1. Invest in the Service only model 2. Invest in the Product only model 3. Do not invest, utilize the stock market for investment gains A 5-year cash flow analysis was conducted to give the founders a recommended strategy to optimize their investment. Through conducting a benefit cost analysis and calculating the internal rate of return of each opportunity, it was determined that both business models may be profitable and worthy investments. The expected IRR of service model and product model are 56% and 136% respectively. They are both much higher than the stock market option, which has an estimated MARR of 8% on average. Much of the risk in this analysis was the uncertainty in the sales revenue projections. The team endeavored to determine the sensitivity of the data by performing sensitivity analysis on these sales projections. Expected values were calculated taking into consideration of the most likely, optimistic and pessimistic cases. The sensitivity analysis result shows both business models are profitable under all conditions. The economic analysis has shown that while both business models are likely to be profitable, the Product Business Model has the potential for a higher return on investment. Therefore the research team recommends that the investors proceed with the Product Business Model outlined in the report.

  Citation × Citation Citation Abstract Copy Title: A Novel Approach to Flow and Sediment Transport Estimation in Estuaries and Bays Author: Moftakhari Rostamkhani, Hamed Year: 2015 Reliable estimates of river discharge and sediment transport to the ocean from large tidal rivers are vital for water resources management, efficient river and harbor management, navigational purposes, and climate analyses. Due to the difficulties inherent in measuring tidal-river discharge, hydrological and sedimentological records are typically too short to adequately characterize long-term (decadal) trends. Also, uncertainties associated with observation and calibration of hydrological models suggest a need for more accurate methods based on longer records of hydrodynamic parameters (e.g. tides). Tidal theory indicates that tides and river discharge interact through quadratic bed friction, which diminishes and distorts the tidal wave as discharge increases. In this study, using tidal constituents, astronomical forcing and a model of the frictional interaction of flow and tides, I propose a novel Tidal Discharge Estimate (TDE) to predict freshwater discharge with an approximate averaging interval of 18 days for time periods with tidal data but no river flow records. Next, using continuous wavelet analysis of tidal properties, I develop a method of estimating river discharge using tides measured on multiple gages along tidal rivers to improve the time-resolution and accuracy of TDE. The applicability of the Multiple-gauge Discharge Estimate (MTDE) is first demonstrated in the two largest tidal-fluvial systems of the Pacific Northwest, the Columbia River Estuary (CRE) and Fraser River Estuary (FRE). A numerical model of an idealized estuary with similar forcing as the FRE and CRE is next run under different hydrologic and morphologic scenarios to evaluate the effect of convergence, friction, and river flow variations on the applicability of MTDE. The TDE method was applied to the San Francisco Bay, using the continuous hourly tide record available since 1858. Results show that TDE reproduces known San Francisco (SF) Bay delta inflows from 1930-present with a Nash-Sutcliffe coefficient of 0.81 and is a useful method for hindcasting historical flows from 1858 - 1929, a period that predates direct measurement of delta discharge. I also recover and digitize ~80 years of Sacramento River daily water level data between 1849 and 1946, from which river discharge to SF Bay is estimated on a daily basis, after adjusting for changes to the river channel. This discharge combined with Net Delta Outflow Index estimates (1930 - 2011) and flow estimates from tidal data (1858 - 2011) provides a more accurate version of SF Bay historic daily inflows from 1849 - 2011. Next, the history of sediment transport and discharge into SF Bay from 1849-present is reevaluated using the daily discharge estimates. A non-stationary rating curve between river flow and sediment transport is developed, with net sedimentation observed during five bathymetric surveys that were used to constrain the total integrated sediment discharge. Results show that ~1600±320 million-tons of sediment have been delivered to SF Bay between 1850 and 2011. There has been an approximately 25 - 30% reduction of annual flow since the 19th century, along with decreased sediment supply. This has resulted in a ~60% reduction in annual sediment delivery to SF Bay. The annual hydrograph of inflow to SF Bay and the seasonality of sediment flux have changed considerably over time, due to both human alteration and climate change. Significant historic spring-melt peak floods have disappeared in the modern system and now peak flows mostly occur in winter. My flow estimation methods also confirm that the flood of January 1862 had the largest daily sediment load and the second largest daily discharge since 1849. Title: A Novel Approach to Flow and Sediment Transport Estimation in Estuaries and Bays Author: Moftakhari Rostamkhani, Hamed Year: 2015 Reliable estimates of river discharge and sediment transport to the ocean from large tidal rivers are vital for water resources management, efficient river and harbor management, navigational purposes, and climate analyses. Due to the difficulties inherent in measuring tidal-river discharge, hydrological and sedimentological records are typically too short to adequately characterize long-term (decadal) trends. Also, uncertainties associated with observation and calibration of hydrological models suggest a need for more accurate methods based on longer records of hydrodynamic parameters (e.g. tides). Tidal theory indicates that tides and river discharge interact through quadratic bed friction, which diminishes and distorts the tidal wave as discharge increases.
