(Ramesh Saligrama), 1964- Vocalization patterns of two groups of captive Francois' langurs (Presbytis francoisi) were studied between August 1989 and June 1990. During the 11 months of observation, 109 hours of vocalization recordings were made at Metro Washington Park Zoo, Portland, and the San Diego Zoo, San Diego. Based on the behavioral observations and the vocalization recordings, two categories of vocalization types are described. Type I consists of 20 basic patterns including infant vocalizations and a vocalization recorded by other observers. Type II consists of 3 patterns related to stereotypic behavior and possible stress under captive conditions. Physical characteristics and the context of behavior for each call type are described. Spectrograms are given for all call types except the loud call. Among the calls recorded, whistle vocalizations of infants are the longest in duration. Comparison of vocalization patterns of P. francoisi to those of other species of the genus Presbytis revealed similarities in behavior and context among some call types in the species of P. entellus and P. johnii.

  Citation × Citation Citation Abstract Copy Title: A household production approach to modeling household recycling effort Author: Martini, Roger Household recycling is an important means by which social costs of solid waste disposal may be reduced. These costs include energy and resource costs of collection and disposal as well as environmental costs from emissions from landfills, incinerators, and collection vehicles. In this thesis, a household production model is used to represent the decision faced by the household in determining the level of effort to commit to recycling activities. The decision regarding the level of effort the household commits to recycling is hypothesized to be a function of economic variables such as the cost of solid waste disposal and expenditure on goods for both direct consumption and as inputs into production in the home, as well as of the demographic characteristics of the household. Two empirical models are developed, using data collected by the Portland Metro Association. The first of these models specifies a linear relationship between recycling behavior and the economic and demographic variables in the model. The second model is somewhat more complex, making use of the indirect utility function of the household. Redacted for Privacy The results of the empirical analysis show that the greater the price change associated with increasing solid waste disposal volume, the greater the probability that the household will devote more effort to recycling. As well, the age and education of the female head of the household and the presence of a child in the home also affect the households decision to recycle. Household recycling may be encouraged by municipal planners by using an escalating price structure for solid waste disposal. Additionally, recycling programs should emphasize convenience over other considerations such as variety of materials collected.

  Citation × Citation Citation Abstract Copy Title: Residential water conservation and energy efficiency impacts through effective scheduling and opportunities for regional expansion : a case study of a gas tankless water heater with recirculation loop Author: Johnson, Erica M. (Erica Marie) This study focused on the potential water and energy savings from implementing a revised schedule of a recirculation pump connected to a condensing gas tankless water heater located in a study home in Portland, Oregon. The existing recirculation pump activation schedule was studied for its impact on the overall water use and energy efficiency of the water heater. Utilizing the recirculation pump for water events was found to reduce overall water consumption by 14.84 times the consumption when not using the recirculation pump. The use of the recirculation pump was also found to reduce the energy efficiency of the water heater by 7.82%. Based on these findings, a revised schedule was developed for homeowner adoption. Regional expansion of this technology was examined through the development of a suitability index that highlighted building and homeowner characteristics likely to lead to technological adoption. This suitability index was applied to a map of the Portland metro area to identify suitability hotspots for energy policy applications on a larger scale. Results of the expanded analysis indicated that there are significant impacts to water consumption and energy efficiency with the adoption of this technology. Policy issues, including incentives for adoption, are discussed in broader context.

  Citation × Citation Citation Abstract Copy Title: An application of regression tree methodology in freeway travel time estimation using speed as a proxy Author: Wang, Lijuan Accurate freeway travel time estimation is of increasing importance for the travelers’ information and route guidance system. A non-parametric statistical methodology known as regression trees is deployed in this research for dynamically and accurately estimating freeway travel times for the I5-I205 loop in the Portland Metro area of Oregon using speed as a proxy. In the absence of historical travel time data on PORTAL (Portland Oregon Regional Transportation Archive Listing), which is the source of data collection in this research, regression tree models are built to predict speeds first and the predicted speeds are in turn used to estimate travel times by mid-point algorithm. The regression tree models in this research are built based on historical data sets, including not only the traffic flow data but also the incident related data, weather data and time of day. This ensures the models will maintain stable prediction ability under both free flow conditions and non-free flow conditions on freeways. Model construction and validation are implemented in the statistical software package S-PLUS. A full regression tree model is constructed on one test data set including 227 daily test data sets randomly selected from the total of 342 daily test data sets collected in the entire year of 2005. To determine what kind of regression tree model should be selected to predict speed or estimate travel time for a certain day under dynamic conditions, a characterization approach is deployed and four characterization standards are setup to track the characteristics of both test data sets and validation data sets. Two experimental designs are constructed to evaluate and compare the performances of eleven regression tree models ─ the full regression tree model and the ten characterization regression tree models. The results show that these eleven tree models possess the ability to accurately predict speeds or estimate travel times. In addition, meaningful results are obtained showing which of these eleven tree models are best to choose for dynamically estimating travel times for a future day.

  Citation × Citation Citation Abstract Copy Title: Northwest forest plan effects on county net migration and employment growth : causality of policy variables, timing of response, relevant time periods, rural vs. metro policy effects and effects on industry employment Author: Eichman, Henry N. County-level net migration and employment growth rates associated with the Northwest Forest Plan (NWFP) are examined. The NWFP area encompasses federal land in 53 Oregon, Washington and California counties; 20 counties adjacent to NWFP counties are also included in the sample. The NWFP was enacted in December of 1993, however, this analysis examines the 24 year time period from 1980 through 2003. Net migration (the change in population due to in-migration and out-migration) and employment growth are represented by a simultaneous equation model (SEM) that is corrected for spatial autocorrelation. While the NWFP land allocations are expected to influence net migration and employment growth, they are potentially determined by similar processes as the endogenous economic indicators. Logistic regression analysis shows the probability that NWFP lands were allocated to biodiversity purposes or to land uses subject to timber harvest depends on natural, political and economic variables. The SEM is run on a yearly basis to explore changes in net migration and employment growth due to policy enactment, future expectations about land allocations, and market fluctuations. These results suggest the time period was characterized by many changes the endogenous variables from the effects of land management. In addition, the yearly analysis suggests that variation in yearly employment growth and net migration may not be sufficient for precise estimation of the effects of the exogenous variables. Pooling the yearly data over policy-relevant time periods is thus appropriate and provides insight into the NWFP effects on the economic indicators. Counties with more land reserved for biodiversity purposes had higher net migration and employment growth. In contrast, counties with more land allocated to extractive uses experienced low net migration. During the period following NWFP enactment, from 1994 to 2003, the classification of land according to NWFP management yields no significant relationship, suggesting adjustment to the NWFP had occurred. The effects of land management variables for rural and metropolitan counties are distinguished in another SEM. Contrary to the popular notion that employment effects were felt in large part by rural counties, this analysis shows changes in employment growth due to policy effects were felt primarily in metropolitan counties within the NWFP region. In addition, higher net migration occurred in rural and metropolitan counties containing land reserved for biodiversity purposes. These counties also experienced a simultaneous increase in employment growth as a result of allocation of these lands. Analysis of employment growth changes in specific industry sectors indicates manufacturing jobs were lost, however, service industry growth was encouraged as a result of NWFP land allocations. In addition, land allocated solely for the purpose of biodiversity services was not associated with changes in the manufacturing employment while potentially promoting growth in service sector employment.
