This study aims to explore the possibility of environmental justice as social consensus and an institutional framework to reduce socioeconomic differences in natural disaster vulnerability through a case study of flood risk management in Johnson Creek, Portland, Oregon. First, by analyzing institutions, policies, and currently ongoing flood mitigation projects, this study investigates how federal and local governments are addressing and responding to current flood problems. Second, through flood expert surveys and GIS spatial analysis, this study examines various factors that contribute to communities' susceptibility to flood risks, and whether there exist spatial differences between physically and socioeconomically vulnerable communities within the Johnson Creek area. Lastly, this study conducted comparative analysis of perceptions using Q-methodology to explore the diverse range of meanings and understandings that flood experts and urban practitioners construct in relation to the dilemmas of environmental justice in flood mitigation practice. The findings of this study indicate that institutional blind spots and barriers in natural disaster mitigation policy and planning can be generated by flood experts' and urban practitioners' different understandings of vulnerability, different interpretations of human rights, and different perspectives on the extent of institutional responsibility to assist socioeconomically vulnerable populations.

This study investigates the hydrologic effects of urbanization in two Portland, Oregon streams through a comparison of three hydrologic metrics. Hydrologic metrics used in this study are the mean annual runoff ratio (Qa), mean seasonal runoff ratio (Qw and Qd), and the fraction of time that streamflow exceeds the mean streamflow during the year (TQmean). Additionally, the relative change in streamflow in response to storm events was examined for two watersheds. For this investigation urban development is represented by two urbanization metrics: percent impervious and road density. Descriptive and inferential statistics were used to evaluate the relationship between the hydrologic metrics and the amount of urban development in each watershed. The effect of watershed size was also investigated using nested watersheds, with watershed size ranging from 6 km2 to 138km 2. The results indicate that annual and seasonal runoff ratios have difficulty capturing the dynamic hydrologic behavior in urban watersheds. TQmean was useful at capturing the flashy behavior of the Upper Fanno watershed, however it did not perform as well in Kelley watershed possibly due to the influence of impermeable soils and steep slopes. Unexpected values for hydrologic metrics in Lower Johnson, Sycamore and Kelley watersheds could be the result water collection systems that appear to route surface water outside of their watersheds as well as permeable soils. Storm event analysis was effective at characterizing the behavior for the selected watersheds, indicating that shorter time scales may best capture the dynamic behavior of urban watersheds.

Contending with a changing climate presents a necessary push for planning. Although climate change is considered a global environmental problem requiring a global commitment and trans-national action, more and more, policymakers are recognizing the vital need for action at the local level. In the US, especially in the absence of national climate legislation, many local governments have begun developing strategic plans, or climate action plans (CAPs), to address adapting to impacts of climate change and mitigating greenhouse gas emissions. This thesis involves case studies of Portland, OR and Chicago, IL, cities with recently adopted CAPs and with considerable recognition in the field. The analysis involves an evaluation each city’s CAP and an evaluation of its implementation. The studies help elicit an understanding of the measures cites are employing to mitigate climate change and determine ways the planning profession can better assist communities in climate policy development and its prompt implementation.

Studies suggest that knowledge, attitudes, and beliefs about domestic violence influence the behaviors of Mexican men. However, few interventions have targeted men in efforts to provide domestic violence awareness and health education to a relevant at-risk community that is also challenged by low literacy. Mexican immigrant men, particularly those less acculturated to the dominant U.S. culture, are significantly less likely to access services and more likely to remain isolated and removed from their communities and, more importantly, from their families. The purpose of this study was to explore and examine how cultural beliefs and behaviors influence the potential of domestic violence from the perspective of the Mexican origin, male immigrant. The research drew on existing community academic partnerships to collaboratively develop a pilot intervention that uses popular education techniques and a Community Based Participatory Research (CBPR) framework. The specific aims were: 1) to use the principles and practices of CBPR to ensure that the issues addressed and results obtained are relevant to Latinos in Multnomah County, 2) to identify the beliefs, attitudes, and culture about domestic violence and male health for a population of men who are immigrants and of Mexican origin, 3) to develop and prioritize intervention strategies that are community defined, 4) to implement and evaluate a four week pilot project that utilizes community defined, literacy independent curriculum and popular education techniques to address male and family wellness and the prevention of domestic violence. Nine men participated in this study who reported inadequate or marginal functional literacy at approximately a 4.5 grade level. The findings also revealed a strong consensus among the participants' that there is confusion surrounding what constitutes domestic violence and/or what behaviors and social barriers place them at risk for health conditions. In summary, we found that the domestic violence in the Latino communities cannot be approached as a single issue; it needs to be embraced from a wellness perspective and the impact of domestic violence and health knowledge is navigated by experiences of one's past and present. Combining the tools of CBPR with the tools of popular education may allow researchers to address the Latino male's concerns with literacy while also examining other, less immediately visible, concerns. When you take the focus off such a delicate subject such as domestic violence and reframe the issue in terms of holistic health, you will then find a more cooperative and less defensive population to work with.

Because of the relative uniqueness of the runaway experience as it now exists, minimal current research information is available. It was our feeling that knowledge about runaways, their families, and the social agencies which serve them is essential if significant prevention and treatment for the problem were to be implemented by the community. The purpose and scope of this exploratory research was essentially two-fold; to contribute descriptive information about runaway youth and their families to the community, and to evaluate the current populations of two agencies which service them. An underlying goal throughout the research was to utilize the data collected to identify trends in runaway behavior, increase the potential for predictability, and provide some real insight into prevention techniques. Our informal hypothesis was that there is a significant difference in specific variables between runaway and non-runaway populations. We were interested in developing a typology of runaways, identifying those factors which increase a child's probability that he/she will run away. Finally, we wanted to know if different agencies tend to serve a particular kind of runaway who has specific characteristics. These constituted the major goals for this research practicum. Since most law enforcement and social service energy is spent at the point of crisis, this research sought to identify trends in the scope of the problem which would aid preventative services for runaways. Hopefully, the impact of this practicum will influence crucial issues in terms of family dynamics, treatment intervention, community resources, and delinquency prevention. The results of this study will be distributed to the participating agencies and other interested segments of the community. Probably more detailed hypothesis testing will be needed; however, this study forms a base of information for future research. Better assessment of meeting the problem by evaluating all existing services should be a continuing focus for the social service community.

The purpose of this study was to identify the mental health services available to the elderly residents of Oregon, and to assess the effectiveness of these services in providing mental health treatment to elderly persons. In order to reasonably narrow the scope of this study, the investigation of mental health services was limited primarily to those agencies which are publicly funded and controlled by state or local bodies. In addition, Multnomah County was selected as a case study area in order to further narrow the scope of the study. Multnomah County was selected because of the convenience of its geographical location for this researcher and Student Public Interest Research Group (OSPIRG) personnel, but more importantly, because Multnomah County is one of the most urbanized areas of the state, with a large number of mental health services geographically accessible to its elderly residents. Additionally, this county contains approximately 31% of all elderly residents in Oregon.

This study is an attempt to develop, design, and implement procedures for better data collection in the future and for an evaluation of the services provided in the past. Conciliation Courts have developed across the country on the notion that case work services can, at best, save a marriage from divorce and, at least, can do no harm. Evaluation of the effectiveness of conciliation services is limited and contradictory. This practicum is an attempt to develop a research design which can measure the effectiveness of conciliation service. We consider the first priority to develop a work­able design which will insure response. A second priority, which will hopefully be developed next, is a value system which will give us data concerning what is effectiveness and which kinds of things need to be and can be measured by a client feedback system .

This research sought to determine the impact of the Older Americans Act of 1965 and its subsequent amendments on the ages population in Portland-Multnomah County from 1965 to 1977. After a comparative analysis of ages services prior to the Act of 1965, and the elderly services subsequent to the Act, the conclusions revealed that there was a significant impact made upon the lives of seniors in Portland-Multnomah County area.

Pretrial release (PTR) is the permanent or temporary freedom from incarceration for criminal defendants awaiting adjudication of their cases in court. From Anglo Saxon times in England, people accused of non-capital crimes were generally permitted to remain free until judicial officials could hear the charges against them. In America, pretrial release has been advocated by the courts since the colonial era. The U. S. Constitution requires that bail not be excessive, but leaves governments free to decide how bail laws are administered. The study briefly traces the historical developments of PTR up to the present time. The study then centers on the PTR process of three Oregon counties (Multnomah, Washington, and Yamhill) and observes the decisions of judges, release assistance officers, and jailers in relation to the release outcomes for a study group (N=619) who were booked into jails of the three counties in 1993. Background data on defendants in the study include gender, race, the crimes for which they were arrested, criminal history, and the disposition of the current charges. Seventy-one percent of the defendants received PTR. Significant factors in the release outcome, as shown by logistic and multiple regression analyses, were probation violation status, felony in the current charge, narcotics offenses in the current charge, and charged with multiple offenses. Gender and race were not strong influences on the release outcome. Hispanic defendants (N = 108) in the study, however, were detained in jail longer than Whites (N=394). Hispanics were less likely than Whites to be released on the same day of arrest and served generally longer jail terms than Whites under similar sentences. Possible explanations are that Hispanics were more frequently charged with distributing narcotics and charged with multiple offenses. Implications suggest further studies on minorities in judicial and corrections settings. The study has applications in judicial and corrections policies on the early release of inmates, an important issue as jails become increasingly overcrowded.

This study investigates the relationship between channel complexity and nutrient spiraling along 31 reaches of an urbanized watershed in Portland, Oregon. Much research shows that urbanization has an effect on watershed hydrology and nutrient loading at the watershed scale for various sized catchments. However, the flux of nutrients over short reaches within a stream channel has been less studied because of the effort and costs associated with fieldwork and subsequent laboratory analysis of the surface water samples. In this study I measure channel complexity and uptake velocity of nitrate to determine if this relationship is indicative of a healthy, functioning stream. I take field measurements and samples to determine the complexity and uptake velocity of each reach. Using ion-selective electrodes, the fluxes of nitrate were measured within each reach; when combined with channel geometry and velocity measurements these measurements allow for the transformation of nitrate fluxes into spiraling metrics. Results show that 18 of the 31 reaches had uptake velocity. Discharge and sinuosity were positively correlated with nitrate uptake velocity. Complexity and nitrate concentration were negatively correlated with nitrate uptake velocity. Grass landcover was positively correlated with nitrate uptake velocity and negatively correlated with nitrate concentration. These results indicate that land use and channel complexity both are related to the in-stream processing of nitrate. The implication of this study is that channel complexity is an important driver of nutrient flux in an urban watershed, and that this technique can be applied in future studies to better characterize water quality of stream channels over short reaches to entire catchments.
