Style Shifting In First-Encounter Conversations Between Japanese Speakers, Kenichi Shinkuma

Dissertations and Theses

This study examines style shift between formal and informal styles in first- encounter conversations between Japanese native speakers and demonstrates how the speakers shifted the speech style in the context. Many researchers have studied this type of style shift and demonstrated that style shifts occur within a single speech context where social factors, such as differences in age, status, and formalness remain constant (e.g., Cook, 2008; Geyer, 2008; Ikuta, 1983; Maynard, 1991; Okamoto, 1999). This study contributed support to these previous studies. In this study, both quantitative and qualitative analyses focusing on Japanese native speakers' use of style shifting in …

The Impact Of Documentation Status On The Educational Attainment Experiences Of Undocumented Hispanic/Latino Students, Brittanie Alexandria Roberts

Dissertations and Theses

The issue of undocumented immigration has recently taken center-stage in the media and national politics in the United States. A large population of undocumented youth grows up with legal access to public education through high school, following the Supreme Court decision of Plyler vs. Doe, but faces legal and economic barriers to post-secondary education. Following high school, undocumented Hispanic/Latino youth legal protections end, greatly limiting chances for upward mobility through traditional post-secondary education pipelines. In some cases, knowledge of future barriers to post-secondary education leads to a decline in educational motivation.

The current political atmosphere makes this study a bit …

Elaborating Patient Agency In Breast-Cancer Care: A Grounded Theoretical Analysis Of Patients Asserting Treatment Preferences, Rachel Sofia Erdman

Dissertations and Theses

Successful physician-patient communication is increasingly being acknowledged as a vital aspect of healthcare today. Research in the field has not examined all aspects of patient-centered care and the aspects that have been studied have not been grounded in actual patient action. The research done in the field has largely been studied quantitatively. The present thesis research attempts to contribute to the gap in the field of physician-patient communication by qualitatively examining patient assertiveness. This thesis examines conversations between women in Portland, Oregon recently diagnosed with breast cancer talking to their surgeons about their diagnoses and treatment options. Using grounded qualitative …

Strengths In Action: Implementing A Learning Organization Model In A Human Service Setting, Barbara Ann Whitbeck

Dissertations and Theses

Although learning organization theory evolved in corporate settings, literature suggests that the theory has much to offer human service organizations. This dissertation examines the implementation of a modified learning organization model in three small field offices of a publicly-funded vocational rehabilitation organization in the Pacific Northwest, at a time when the organization was negotiating financial cutbacks and organizational changes. The model - known as Strengths in Action - was based on Senge's five learning organization disciplines, and informed by organizational culture theory. In each participating office, all staff worked together to set a goal, make a plan, and achieve the …

Understanding Sexual Assault Survivors' Willingness To Participate In The Judicial System, Mildred Ann Davis

Dissertations and Theses

This dissertation examined the relationship between support services for adult survivors of sexual assault and judicial outcomes. Specifically, this study explored survivors' willingness to participate in the judicial process. Although "victim unwilling to participate" is the primary reason given by the police for cases not progressing to prosecution, we know little about most aspects of survivors' willingness to participate in the judicial process, especially beyond initial reporting of the assault. The steps to prosecution are dependent on one another yet a survivor's willingness to participate in these steps is a fluid process. The primary research question explored was Are there …

The Objective Vs. The Perceived Environment: What Matters For Active Travel, Liang Ma

Dissertations and Theses

This study aims to explore the relationship between the objective (actual) environment and people's perceptions of the environment, and their relative effects on active travel behavior, particularly bicycling behavior. This is an important research gap in the current literature linking the built environment and active travel. Better understanding this relationship will help to explore the mechanism underlying the built environment- behavior relationship and identify potential interventions to promote active travel.

Relying on the data from Portland, OR, this study investigated the following four research questions: (1) How does the objectively measured environment correspond to the perceived environment? And what factors …

Changing The Face Of The Earth: The Morrison-­Knudsen Corporation As Partner To The U.S. Federal Government, Christopher S. Blanchard

Dissertations and Theses

Beginning with reclamation projects in the western U.S., the heavy construction industry helped the federal government grow in size and sophistication in the twentieth century. The Morrison-­Knudsen Corporation throughout the twentieth century represented one of the federal government's favored contractors. Following western reclamation projects, the U.S. federal government then used contractors to help move the U.S. economy out of the Depression, prepare for World War II, wage the Cold War at home and abroad, and win the space race. Thus, at key stages in United States history we observe the necessity of the U.S. federal government partnering with the heavy …

Assessing Generic And Program-Specific Dose-Response Relations Between Engagement In Contemplative Practices And Reductions In Teachers' Occupational Stress And Burnout, Jessica Leigh Harrison

Dissertations and Theses

Teaching is a stressful, uncertain, and emotionally laden profession (Chaplain, 2008; Farber, 1999; Johnson et al., 2005). One approach to reduce psychological distress and improve well-being in teachers is through the use of mindfulness-based stress reduction (MBSR) programs. While MBSR programs have been shown in several studies to be effective with regard to improving well-being in teachers, little research has been done to date examining the relationship between program dose and outcomes. This study examines the relationship between both generic and program-specific dose and outcomes of stress and burnout. Results showed some evidence that generic yoga frequency is related to …

"Your Information Station": A Case Study Of Rural Radio In The 21st Century, William Jacob Amadeus Pinnock

Dissertations and Theses

The study examined how the introduction of high-speed internet into a rural community affected audience members' use of their local radio station. A qualitative case study was guided by uses and gratifications and niche theory. The author conducted interviews with KMMR FM audience members in Malta, Montana, to investigate how the introduction of high-speed internet impacted listener habits. Twenty participants who either listened to or produced content for KMMR FM were interviewed. The author performed a thematic analysis of different uses for the radio guided by typologies created by Rubin (1983), Palmgreen and Rayburn (1979), and Katz, Haas, and Gurevitch …

Latino Men Managing Hiv: An Appraisal Analysis Of Intersubjective Relations In The Discourse Of Five Research Interviews, Will Caston

Dissertations and Theses

Latino men, particularly those who have sex with other men, have been disproportionately affected by HIV/AIDS. Scholars have sought for nearly two decades to understand how various social and cultural factors in the Latino community exacerbate HIV risk among these men. Although following the advent of life-sustaining medications in 1996, HIV is often regarded as a manageable chronic illness, as opposed to a death sentence, scant attention has been devoted to how HIV-positive Latino men experience managing the illness. Among studies that have focused on HIV-positive persons' illness management, few Latino men have participated.

Using the Appraisal framework from Hallidayan …

The Stories We Tell: A Qualitative Inquiry To Multiracial Family Storytelling, Mariko O. Thomas

Dissertations and Theses

A narrative inheritance is comprised of the stories told by family members that are received by a younger generation and used to help construct identity. According to the communication theory of identity, identity is formed through communication. Additionally, the storied resource perspective looks at narratives as a major method of creating and maintaining identity. This study looks at the kinds of narrative inheritance concerning race that people in multiracial families receive and possible ways it affects racial identity formation. Findings from 12 semi-structured interviews indicate that narratives of racism, cultural pride, and hardship are prevalent in multiracial families. Additionally, findings …

Bicyclists' Uptake Of Traffic-Related Air Pollution: Effects Of The Urban Transportation System, Alexander Y. Bigazzi

Dissertations and Theses

While bicyclists and other active travelers obtain health benefits from increased physical activity, they also risk uptake of traffic-related air pollution. But pollution uptake by urban bicyclists is not well understood due to a lack of direct measurements and insufficient analysis of the determinants of exposure and ventilation (breathing). This knowledge gap impedes pollution-conscious transportation planning, design, and health impact assessment.

The research presented in this dissertation generates new connections between transportation system characteristics and pollution uptake by bicyclists. The primary research questions are: 1) how do urban bicyclists' intake and uptake of air pollution vary with roadway and travel …

The Effect Of Social Media On Public Awareness And Extra-Judicial Effects: The Gay Marriage Cases And Litigating For New Rights, Sarahfina Aubrey Peterson

Dissertations and Theses

When the Supreme Court grants new rights, public awareness is a crucial part of enforcement. Gerald N. Rosenberg and Michael J. Klarman famously criticized minority rights organizations for attempting to gain new rights through the judiciary. The crux of their argument relied heavily on the American media's scanty coverage of Court issues and subsequent low public awareness of Court cases. Using the 2013 United States v. Windsor and Hollingsworth v. Perry rulings as a case study, I suggest that the media environment has changed so much since Rosenberg and Klarman were writing that their theories warrant reconsideration. Minority rights groups …

The Ground Slate Transition On The Northwest Coast: Establishing A Chronological Framework, Joshua Daniel Dinwiddie

Dissertations and Theses

This thesis establishes the earliest appearance of ground slate points at 50 locations throughout the Northwest Coast of North America. Ground slate points are a tool common among maritime hunter-gatherers, but rare among hunter-gatherers who utilize terrestrial subsistence strategies; ground slate points are considered one of the archaeological hallmarks of mid-to-late Holocene Northwest Coast peoples. The appearance of ground slate points in the archaeological record is frequently marked by a concurrent decline in the prevalence of flaked stone points, a phenomenon often referred to as "the ground slate transition." Until now, the specific timing of the appearance of these tools …

"But There's A Black History Month": A Content Analysis Of Ideological Framing And Presentation In White Nationalist Publications, Dylan Tomas Waite

Dissertations and Theses

The political climate in America continues to become more polarized each year. The "left" and "right" political parties are locked in near-constant struggle and it is often the people whom they are meant to serve that suffer the harshest effects of this struggle. This mainstream political posturing and hostile behavior has allowed for the continued presence, and some say resurgence, of racially motivated right-wing nationalist groups. Groups such as the Ku Klux Klan, the Aryan Nations and racist Skinheads have seen periods of strength and decline throughout American history. In the late 20th and early 21st Centuries they have begun …

Nuwuvi (Southern Paiute) Ecological Knowledge Of Piñon-Juniper Woodlands: Implications For Conservation And Sustainable Resource Use In Two Southern Nevada Protected Areas, Brian John Lefler

Dissertations and Theses

Nuwuvi (Southern Paiute) have inhabited the southern Great Basin for thousands of years, and consider Nuvagantu (where snow sits) in the Spring Mountains landscape to be the locus of their creation as a people. Their ancestral territory spans parts of Nevada, Utah, Arizona, and California. My research identifies and describes the heterogeneous character of Nuwuvi ecological knowledge (NEK) of piñon-juniper woodland ecosystems within two federal protected areas (PAs) in southeastern Nevada, the Spring Mountains National Recreation Area (SMNRA) and the Desert National Wildlife Refuge (DNWR), as remembered and practiced to varying degrees by 22 select Nuwuvi knowledge holders. I focus …

Dialogue In Identity-Based Conflict (Study Of Intergroup-Dialogue With University Students), Lisha Shrestha

Dissertations and Theses

An individual's struggle with "self," which consists of personal identity and social identity, can create both intra- and interpersonal conflict. In this study, I explored how such struggles inform identity-based conflict and how such conflicts are addressed by intergroup dialogue. A dialogue was conducted with University students, consisting of discussions about participants' struggles with "self" and social identity. These conversations were analyzed using a mixed methods and content analysis approach. The study revealed that identities such as gender play significant roles in creating conflict within "self" and with others. National origin, race, and ethnicity also affect personal identity; however, these …

Bicycle Level Of Service: Where Are The Gaps In Bicycle Flow Measures?, Pamela Christine Johnson

Dissertations and Theses

Bicycle use is increasing in many parts of the U.S. Local and regional governments have set ambitious bicycle mode share goals as part of their strategy to curb greenhouse gas emissions and relieve traffic congestion. In particular, Portland, Oregon has set a 25% mode share goal for 2030 (PBOT 2010). Currently bicycle mode share in Portland is 6.1% of all trips. Other cities and regional planning organizations are also setting ambitious bicycle mode share goals and increasing bicycle facilities and programs to encourage bicycling. Increases in bicycle mode share are being encouraged to increase. However, cities with higher-than-average bicycle mode …

Explorations Into The Psycholinguistic Validity Of Extended Collocations, J. Arianna Morgan

Dissertations and Theses

This study tests the hypothesis that frequency and collocational association make independent contributions to the processing time of English multiword collocational, phrases for L1 and L2 English speakers. The results suggest that these constructs do play a role in the processing of 4-word, corpus-extracted phrases. In this sample, L1 speakers demonstrated reduced processing time for both highly frequent and highly associated phrases, while L2 speakers demonstrated reduced processing time for highly frequent phrases. Evidence exists in the data that highly proficient L2 speakers may develop similar patterns of reduced processing time as L1 speakers. Additionally, some L1 speakers did not …

Controlling The Empire: Measuring Ethnic Residential Segregation In London, 2001-2011, Lindsay Joella Spell

Dissertations and Theses

This research presents an overview of ethnic residential segregation in London, England, from 2001 to 2011 using four different methods of measurement. The purpose of the study was to both examine changes in the level of segregation among different ethnic groups between census dates and to compare various methods of measurement. Using the Index of Dissimilarity, Poulsen et al.'s (2001) typology classification and two different local statistics (Getis-Ord G* and Anselin Local Moran's I), the levels of concentration of the five main ethnic minority groups in London were measured for data from the 2001 and 2011 censuses. The five ethnic …

A Cross-Sectional Study Of Student-Athlete Needs Satisfaction And Well-Being, Abigail M. Gunnink

Dissertations and Theses

Grounded in self-determination theory (Deci & Ryan, 2000), the purpose of this study was to examine (a) the effects of the social environment, as defined by the divisions of the Department of Athletics, on student-athletes' perceptions of basic needs satisfaction, (b) the effects of basic needs satisfaction on well-being, and (c) the effects of time demands, during in-season and off-season, on well-being, among student-athletes at Portland State University (PSU). Participants were student-athletes at PSU (n = 118). The participants completed a multi-section survey assessing basic needs satisfaction and well-being. Cumulative mean scores highlighted the satisfaction of the basic psychological needs …

Community Connections: Exploring The Constructive Potential Of Facebook For Civic Engagement, Sarah Ruth Martin

Dissertations and Theses

Recognizing the importance of civic engagement to the health of local communities and the overall success of a democracy, this research sought to better understand the relationship between online media use and civic engagement. Specifically, the constructive potential of the social networking site Facebook was explored using the theoretical framework of communication infrastructure theory (CIT; Ball-Rokeach, Kim, & Matei, 2001). Results of a cross-sectional survey with a national sample of 375 participants indicated that Facebook does hold potential for civic engagement. The two most important findings of the research were that Facebook facilitated connection to neighborhood storytelling and that connection …

Dissertations and Theses

The purpose of this thesis is to explore the experiences of single fathers and their roles as primary caregiver to their children as men in society adopting traditionally feminine roles. There was one primary research question explored: How do single father's experience parenthood? This is explored through four sub questions and discussions about daily life and childrearing alone; childcare and work and family conflicts; use of services and support networks; and of particular interest, gender and the influence of masculinity. Through an analysis of interviews with 14 fathers of varying class status, age, education, and time spent as a single …

The Relationship Between Mindfulness And Burnout Among Master Of Social Work Students, Jolanta Maria Piatkowska

Dissertations and Theses

Social work students frequently endure elevated levels of prolonged stress and psychological affliction that might result in serious consequences, such as development of burnout. Some experts suggest that burnout originates in the exposure to chronic interpersonal stressors in the work environment. Yet, there is emerging evidence suggesting that mindfulness practice might be beneficial in alleviating stress. Thus, the purpose of this exploratory study was to examine the relationship between mindfulness and burnout among Master of Social Work students. Burnout, mindfulness, religiosity, spirituality and their potential relationship were discussed and related to previous scholarly literature. Specifically, this study focused on testing …

The Impact Of Wiki-Based Collaborative Writing On English L2 Learners' Individual Writing Development, Gina Christina Caruso

Dissertations and Theses

Although the benefits of group and pair work in the second language (L2) classroom have been extensively studied, most documented research has focused on the use of oral tasks and spoken interaction between learners. Recently however, researchers have begun to investigate the advantages of collaboration on written work. More specifically, with the advancements in computer technology and web-based collaborative platforms like wikis, there has been a growing awareness of the educational possibilities of wikis to enhance L2 writing instruction. This study followed a pretest/posttest repeated measures design to investigate the impact and students' perceptions of wiki-based collaborative writing activities on …

The Role Of Diversity In Peer Influences On Students' Academic Engagement, Hyuny Clark-Shim

Dissertations and Theses

Children's classroom engagement is important for their learning and academic achievement. Extending Kindermann's (2007) study of peer influence on adolescents' engagement to an ethnically homogeneous sample, the current study examined how different aspects of diversity affect the peer influence process. Three types of diversity were considered: ethnic diversity existing at the school level, relational diversity at the peer network level, and motivational diversity at the group level. Ethnic diversity was observed in the student body as well as among school teachers and staff. Relational diversity was measured by z-scores resulting from binomial tests reflecting how closely two pair of individuals …

The Responsibility To Protect And International Law: Moral, Legal And Practical Perspectives On Kosovo, Libya, And Syria, William R. Blackford

Dissertations and Theses

Humanitarian intervention has long been a secondary or tertiary concern in a security driven international system. Since NATO's intervention during the Kosovo crisis in 1999 there have been significant developments in both the language and form of humanitarian intervention as a matter of international law. The events in Kosovo sparked debate about how to handle humanitarian crisis in the future and thus humanitarian intervention evolved into a redefinition of sovereignty as responsibility and the Responsibility to Protect. The Responsibility to Protect has had a number of opportunities to continue to evolve and assert itself in an international legal context throughout …

Socio-Spatial Transformation And Contested Space At The Street Level In Latin America: The Case Of Cali, Colombia, Maria Janeth Mosquera Becerra

Dissertations and Theses

Since 2008, more than 50% of the world's population has lived in cities and it is projected that by 2050 around 87% will do so. Designing infrastructure in urban spaces has become increasingly critical for achieving human well-being. This dissertation examines socio-spatial transformation processes related to urbanization, economic development and the marginalization of utilitarian cycling in Cali, Colombia, as a particular expression of the struggle for transportation space occurring in urban areas. The research analyzes (a) the socio-spatial processes that have restricted the use of bicycles as a means of transportation in the city of Cali, Colombia; and (b) the …

Using Gist Features To Constrain Search In Object Detection, Joanna Browne Solmon

Dissertations and Theses

This thesis investigates the application of GIST features [13] to the problem of object detection in images. Object detection refers to locating instances of a given object category in an image. It is contrasted with object recognition, which simply decides whether an image contains an object, regardless of the object's location in the image.

In much of computer vision literature, object detection uses a "sliding window" approach to finding objects in an image. This requires moving various sizes of windows across an image and running a trained classifier on the visual features of each window. This brute force method can …

Cross-Cutting Concerns: The Varying Effects Of Partisan Cues In The Context Of Social Networks, Benjamin King Smith

Dissertations and Theses

The theory of motivated reasoning predicts that partisan cues in the media will affect political attitudes, by encouraging individuals to align their views with those of their party's elites. The effect has primarily been tested by looking at issues which have pre-established partisan positions (e.g. immigration reform, gay rights, etc.). This study looks at the effects of partisan cues in the media on attitudes toward a non-partisan issue, the NSA's collection of American's meta-data. Additionally, the study extends research on partisan cues by exploring the moderating role of an individual's political communication network and, specifically, exposure to cross-cutting political communication. …
