While Portland, Oregon's sustainable food movement wins accolades for explicitly situating itself in opposition to the industrialized global food system, it often fails to address systems of oppression that are reproduced within the alternative agri-food movement itself. This demonstrated aversion towards the messy, complex, contingent nature of the social world reflects larger processes of "de-politicization" of the overall sustainability agenda, which leads to the favoring of technological and/or spatial solutions that may undermine the social equity and justice dimensions of the "triple bottom line." This thesis focuses on an action research project involving a series of community dialogues that provided participants with a common language and understanding necessary to interrogate issues of race and class in Portland's sustainable food movement while developing visions for possible futures. Dialogue participants may find new ways to communicate, learn, identify common goals and best practices, and potentially network, collaborate and/or co-produce transformative anti-oppression strategies that integrate into the sustainable food movement. By asking those vested in the sustainable food movement to interrogate dimensions of anti-oppression consciousness, the movement becomes fortified with voices better equipped to envision sustainability within a more political and contingent reality that recognizes conflicts of power, and less resembling an idyllic, utopian, and ultimately impossible sustainability. This thesis delivers some preliminary outcomes following the dialogue series by describing and reflecting on the series' implementation and processes, and reflecting on its impact on participants' anti-oppression consciousness in the context of food and sustainability, while discussing possibilities for future scholarship.

In the early twentieth century industrial, political, and social conflicts occurred throughout the United States during a period of rapid industrialization and modernization. Examples of these disputes, such as labor strikes and political struggles, have frequently been the subjects of scholarly investigations. Yet certain aspects of these conflicts remain relatively unknown, particularly on the community and local levels. The purpose of the present study was to explore and provide the context for a better understanding of the motives behind the responses of antiradicals to left-wing radicalism. What were some of the social, cultural, and economic motivations of local antiradicals in the city of Portland from 1917 to 1941?

This thesis explores the use of identity politics within the atheist movement at both the national and individual levels. I conducted a content analysis of two national atheist groups and three best-selling atheist authors in order to assess the use of atheist identity politics at the national level. I then conducted 15 in-depth interviews with a sample of atheists in Portland, Oregon about their atheist identity and their reactions to and identification with national atheist movement strategies. Findings suggest that national atheist organizations and atheist authors are using a strategy of identity politics that encourage atheists to "come out" as atheists, complain about church/state violations, and criticize religion's influence in American society. They liken their movement to the gay identity movement and argue that as more atheists "come out", they will see less stigma and more respect towards atheists. However, individual atheists do not always identify with these movement strategies. Most participants said that atheism is not a particularly salient identity for them and thus most did not see themselves participating in atheist activism. Further, they implied that they experience little stigma in their everyday lives and are more concerned with promoting religious tolerance and secular policies. I argue that the lack of social identification with atheism, combined with limits to the gay analogy, are likely inhibitors to the success of an atheist movement.

This study takes a cultural perspective in studying the "Alberta Arts District," a gentrifying neighborhood in Northeast Portland in which bohemian cultural production/consumption has become the dominant and commodified vision of the community. Survey data demonstrates residents' general opinions and levels of participation in the changing neighborhood. Forty long-time residents, black and white, homeowners and renters, are interviewed in-depth regarding their perceptions of change. Long-time residents of gentrifying neighborhoods are often overlooked as a less powerful group that only has to negotiate rising rents and property values. This study approaches the meaning of neighborhood changes for long-time residents who have the potential to react culturally, socially, and economically in a neighborhood where racial and economic differences are structured by segregation and divestment. In the course of identifying positive, negative, and mixed feelings about changes, long-time residents also establish their belonging in the neighborhood as it changes around them. This is often done through constructing symbolic boundaries around newcomers, new businesses, and new cultural events in the neighborhood. This study finds that although most long-time residents perceive changes to be positive, race and homeownership affect different outcomes for different groups. Particularly, long-time black residents may establish belonging as being black in a diminishing black community, whereas long-time white homeowners may establish belonging by being homeowners in the context of positive changes.

Emissions inventories are an important tool, often built by governments, and used to manage emissions. To build an inventory of urban CO2 emissions and other fossil fuel combustion products in the urban atmosphere, an inventory of on-road traffic is required. In particular, a high resolution inventory is necessary to capture the local characteristics of transport emissions. These emissions vary widely due to the local nature of the fleet, fuel, and roads. Here we show a new model of ADT for the Portland, OR metropolitan region. The backbone is traffic counter recordings made by the Portland Bureau of Transportation at 7,767 sites over 21 years (1986-2006), augmented with PORTAL (The Portland Regional Transportation Archive Listing) freeway traffic count data. We constructed a regression model to fill in traffic network gaps using GIS data such as road class and population density. An EPA-supplied emissions factor was used to estimate transportation CO2 emissions, which is compared to several other estimates for the city's CO2 footprint.

This study explored the nature of community power and decision-making surrounding the renaming of Portland's Union Avenue in honor of the slain civil rights leader, Martin Luther King, Jr. Employing an integrated theoretical framework based on G. William Domhoff's (1967) perspective of the compatibility of c. Wright Mills' Power Elite Model (1956) and Robert A. Dahl's Pluralist Model (1961) plus Claude s. Fischer's (1982) perspective on the nature of the urban social environment, this study attempted to provide insight into and understanding of the dynamics involved in the controversy that developed over the efforts to rename a street for Dr. King, the decision-making process, and the apparent motivations of the participants.

This study reports on the hypothesized raising of the low, front vowel /æ/, which is characteristic of a regional dialect vowel shift found in cities of the Midwest and Eastern North of the United States. The raising of this vowel is the primary change in a series of vowel shifts that have traditionally been attributed to this region of the U.S. The purpose of this study is to document the production of this vowel by residents of Portland, Oregon, in order to see what light it can shed on dialect research of the Pacific Northwest, especially across age groups to see if it can be implicated in language change. Data were collected by interviewing a convenience sample of twenty-four Portland speakers. Twelve females and twelve males from three different age groupings were interviewed. The interviews were tape recorded and portions of the tapes were analyzed. There was a two-part analysis of the data: 1) Formant measurements (in Hz) were measured with PCQuirer speech analysis software, 2) These measurements were plotted on a graph with Plotnik graphing software. The study found that /æ/ produced by Portland speakers is not following Labov's theory of language change and is therefore not raising. However, some initial speculations of the lowering and fronting of this vowel can be made by the data. The study found that the working class subjects produced a more fronted vowel, and that the younger subjects produced a more fronted and lowered variant of the vowel when compared to the other subjects. The study concludes that the patterns found do not clearly support Labov's paradigm of language change and are therefore only initial speculations.

The effects of urbanization and continual human disturbance on the plant and avian communities of Forest Park and forested lands surrounding Portland, Oregon, were studied. I examined characteristics of plant and avian communities at 25 sites, 24 which were in Forest Park and surrounding areas and one which was in the Ancient Forest Preserve (old-growth stand) northwest of Forest Park. Data were analyzed using multiple regression, ANOV A, and Bonferonni/Dunn. Seven variables were selected representing different urbanization gradients. An additional covariable coded for the old-growth stand, allowing it to be used as a control. Many tree variables, especially those related to shade-tolerant species, were positively correlated with both the distance from downtown Portland and the number of houses in the surrounding area, and negatively correlated with the distance from the nearest forest edge; however, many shrub and herbaceous variables were negatively correlated with the distance from downtown Portland. Species diversity for herbaceous and shrub species was greater at more urban sites, but diversity of trees was lower at more urban sites. There were significantly more non-native species of plants in the city section. I found significantly fewer saplings and small trees, especially shade-tolerant species, in the section of Forest Park closest to downtown Portland, although tree mortality was positively correlated with distance from Portland. Summer bird data revealed significant increases in the abundances of urban and edge species at more urban sites, with concomitant reductions in forest species. There were significantly more ground gleaning birds and short distance migratory species. I also found a significantly greater abundance of birds in the old-growth stand during the winter. This increase was positively correlated with the depth of snow in the nearby Cascade Mountains. My results indicate that Forest Park is apparently progressing in a normal successional pattern with the exception of the city section. The reduction in shade tolerant saplings and small trees in the city section suggest that rate of succession has been slower at more urban sites. Avian data suggest that urbanization affects bird species abundance and guild composition in the more urban areas.

The purpose of this study is to examine which language skills university professors believe are most essential for academic success in Portland State University classes. The study can shed light on a question for future research: Do current academic ESL classes at Portland State University teach the necessary skills to help international students maximize their second-language learning potential in university-level courses. Enrollment statistics for 1993 I 94 show 53 percent of the 815 international students declared majors in two programs: the school of Business Administration and the school of Engineering and Applied Science. This study asked 31 instructors from business and engineering to assess which language skills--reading, writing, listening or speaking--were most important to success in their undergraduate and graduate classes; how they used the language skills; how international students performed in their classes compared with native speaking students; and to describe any critical incidents which appeared to have been caused by lack of comprehension of orally-presented materials. Interview questions were designed to establish a profile of each class and assess the relationship between the amount of culturally-embedded vocabulary and the degree of difficulty experienced by non-native speaking students. Three patterns emerged from the research. First, the ranking of language skills followed results of earlier national surveys showing the importance of reading and listening. All faculty ranked reading the "most important" language skill; reading and listening were ranked equally "most important" by engineering faculty; and writing varied by level and discipline; and speaking was ranked "least important" by all faculty. Second, all faculty ranked textbooks the preferred use of reading skills; note taking was the most-used listening skill; and class discussion was the mostused speaking skill. Writing activities varied by level and discipline, although reports and essay answers were the most frequently mentioned uses. Third, faculty said international students performed better in quantitative than qualitative classes. Within both disciplines, classes which manipulated numbers were less problematic than those which manipulated language with culturally-embedded context or vocabulary. Implications for ESL curriculum design suggest emphasis on skills considered most important by academic faculty.

For a number of reasons--congestion, public health, greenhouse gas emissions, energy use, demographic shifts, and community livability to name a few--the importance of walking and bicycling as transportation options will only continue to increase. Currently, policy interest and infrastructure funding for nonmotorized modes far outstrip our ability to model bike and walk travel. To ensure scarce resources are used most effectively, accurate models sensitive to key policy variables are needed to support long-range planning and project evaluation, and to continue adding to our growing understanding of key factors driving walk and bike behavior. This research attempts to synthesize and advance the state of the art in trip-based, nonmotorized mode choice modeling. Over the past fifteen years, efforts to model the decision to walk or bike on a given trip have been hampered by the lack of a comprehensive behavioral framework and inconsistency in measurement scales and model specification. This project develops a mode choice behavioral framework that acknowledges the importance of attributes along the specific walk and bike routes that travelers are likely to consider, in addition to more traditional area-based measures of travel environments. The proposed framework is applied to a revealed preference, GPS-based travel dataset collected from 2010-2013 in Portland, Oregon. Measurement of nonmotorized trip distance, built environment, tour-level variables, and attitudinal attributes as well as mode availability are explicitly addressed. Route and mode choice models are specified using discrete choice techniques, and predicted walking and bicycling routes are tested as inputs to various mode choice models. Results suggest strong potential for predicted route measures to enhance walk and bicycle mode choice modeling. Findings also support the specific notion that bicycle and pedestrian infrastructure contribute not only to route choice but also to the choice of whether to bike or walk. For decisions to bicycle, availability of low-traffic routes may be particularly important to women. Model results further indicate that land use and built environments around trip ends and a person’s home still have important effects on nonmotorized travel when controlling for route quality. Both route and area travel environment impacts are mostly robust to the inclusion of residential self-selection variables, consistent with the idea that built environment differences matter even for households that choose to live in a walkable or bikeable neighborhood. The combination of area and route-based built environment measures alongside trip context, sociodemographic, and attitudinal attributes provides a new perspective on nonmotorized travel behavior relevant to both policy and practice.
