Using Landsat Tm Imagery To Monitor Vegetation Change Following Flow Restoration To The Lower Owens River, California, Lesley Crandell Bross

Dissertations and Theses

Rehabilitating river corridors to restore valuable riparian habitat consumes significant resources from both governments and private companies. Given these considerable expenditures, it is important to monitor the progress of such projects. This study evaluated the utility of using Landsat Thematic Mapper remotely-sensed data from 2002 and 2009 to monitor vegetation change induced by instream flow restoration to the Lower Owens River in central California. This study compared the results of an unsupervised classification with an NDVI threshold classification to appraise the resources required and effectiveness of each analysis method. The results were inspected by creating standard remote sensing accuracy error …

Coyotes On The Web: Understanding Human-Coyote Interaction And Online Education Using Citizen Science, Zuriel Anne Rasmussen

Dissertations and Theses

Coyote (Canis latrans) numbers are increasing in urban areas, leading to more frequent human-coyote interactions. Rarely, and particularly when coyotes have become habituated to humans, conflicts occur. Effective education about urban coyotes and how to prevent habituation reduces conflict. Citizen science, in the form of online education, can be used to engage and educate city dwellers about urban coyotes. In this research, I explore Portland Metropolitan Area (PMA) residents' baseline experiences with, and attitudes toward, urban coyotes. Next, I investigate citizen science as a tool for education. Using the Portland Urban Coyote Project (PUCP), a citizen science project, as a …

Check-In Frequency With Friends On Location-Based Social Networks: A Look At Homophily And Relational Closeness, Jacqueline H. Vo

Dissertations and Theses

This study examines factors associated with the frequency with which users of location-based social networks (LBSNs) "check-in" with their "friends." In addition to a variety of control factors (i.e., sex homophily, race homophily, geographic proximity, length of friendship, and "friendship" type, including non-romantic friend, romantic partner, and family), the central factors of interest were users' background and attitude homophily with, and relational closeness to, their "friends." Results demonstrate that relational closeness and "friendship" type (i.e., romantic partner) were significantly, positively associated with "check-in" frequency.

Thinking About Work At Home: Implications For Safety At Work, Frankie Guros

Dissertations and Theses

Safety at work is of the utmost importance to employees and the organizations they work for, and as such, it is a central issue for occupational health psychology. Although dramatic decreases in the number of worker injuries and fatalities have been observed over the last several decades, safety remains a principal concern for organizations. This is especially true in occupations in which employees face serious threats to their personal safety, such as correctional officers (COs). While a number of studies have identified workplace factors that contribute to worker safety, few have attempted to draw a link between employee nonwork experiences …

The Development Of Personal Resources In The Academic Domain: Age Differences In The Evolution Of Coping And Perceived Control And The Process Structures That Facilitate Academic Engagement, Teresa Marie Greene

Dissertations and Theses

Studies investigating the development of perceived control and coping in the academic domain generally adopt an individual differences approach, reporting mean-level changes in these and associated constructs. Very few studies attempt to chart the process by which these personal resources exert individual and combined influences on academic outcomes, such as motivation and achievement, in light of normative developmental changes. Further, a consideration of reciprocal influences of these constructs on developmental changes and the contribution of social partners to these processes is not common.

Conceptualized from a systems perspective, this study integrates these different approaches in a longitudinal inquiry into the …

Advances In Autonomous-Underwater-Vehicle Based Passive Bottom-Loss Estimation By Processing Of Marine Ambient Noise, Lanfranco Muzi

Dissertations and Theses

Accurate modeling of acoustic propagation in the ocean waveguide is important to SONAR-performance prediction, and requires, particularly in shallow water environments, characterizing the bottom reflection loss with a precision that databank-based modeling cannot achieve. Recent advances in the technology of autonomous underwater vehicles (AUV) make it possible to envision a survey system for seabed characterization composed of a short array mounted on a small AUV. The bottom power reflection coefficient (and the related reflection loss) can be estimated passively by beamforming the naturally occurring marine ambient-noise acoustic field recorded by a vertical line array of hydrophones. However, the reduced array …

Insights Into The Mental Imagery And Gestural Awareness Of Representational Gestures Produced In Everyday Talk: An Exploratory Study Of Using Participants' Comments As Data, Sue M. Wendel

Dissertations and Theses

To better understand representational gestures used in everyday talk, this study explores the ways participants talk about their own mental imagery and gestural awareness, and how their comments affect analysis. Literature pertaining to representational gestures, mental imagery, gestural awareness, and self-report data provide the theoretical framework for the study's design and implementation. Data is drawn from observations of two video recorded dyads engaged in everyday conversation, and four audio recorded interviews with each participant individually as they viewed and commented on selected video segments in which they had produced a representational gesture. Findings indicate that participants talked about mental imagery …

Fathers Caring For Children With Special Health Care Needs: Experiences Of Work-Life Fit, Claudia Sellmaier

Dissertations and Theses

Research about employed fathers of children with special health care needs (SHCN) is still limited, leaving fathers without the necessary workplace and community supports to better integrate work and life. Caregivers with exceptional caregiving responsibilities report greater levels of work-family conflict and considerable caregiver strain, as well as negative employment and financial consequences related to their caregiving responsibilities. These caregivers often struggle to access community supports such as childcare, after-school care, and support from friends and neighbors.

This study provides insights into the types of job, home, and community resources that are relevant for fathers of children with SHCN in …

Beyond Fruit: Examining Community In A Community Orchard, Emily Jane Becker

Dissertations and Theses

The Fruits of Diversity Community Orchard, located in Portland, Oregon in an affordable housing neighborhood, is a site of alternative food provisioning in which a group of people, organized by two nonprofits, work together to manage fruit and nut producing plants. Through conversations with volunteers who participate regularly and participant observation, this study explores the questions: What does community mean in the context of a community orchard? In what ways does partnering with a nonprofit from outside the neighborhood influence community and the way the project is operationalized?

This thesis situates community orchards within the literature on alternative food networks …

Metaphorical Framing Of Obesity, Ryan Paul Hofer

Dissertations and Theses

The study of metaphor has moved from abstraction and poetics into the realms of cognitive science and cultural studies. Rather than being seen as purely figurative and secondary to literal meaning, investigation of metaphors reveals a close relationship to our processes of reasoning, a capacity to both reveal and cover, and a plasticity that forms within surrounding cultural values. I reviewed current metaphor theory, including its concerns and justifications, and designed a simple survey experiment through the Qualtrix webpage. The survey was distributed via the Amazon Mechanical TURK system. The experiment, in two different versions, briefly described obesity and then …

Gender Difference In Working Parents' Perceptions Of Work/Family Conflict And The Role Of Occupational Prestige, Heather Kirsten Mccabe

Dissertations and Theses

As many Americans move away from the traditional homemaker-breadwinner family model, research on gender and work/family conflict has become increasingly important and the question of gender difference in experiences of work/family conflict continues to be relevant. While there is research that shows women tend to experience significantly greater work/family conflict than men, there are also studies that have shown little or no gender difference, and some that offer evidence that men are reporting more work/family conflict. This study contributes to the debate by examining gender and occupational prestige in regard to working parents' perceptions of work-to-family and family-to-work spillover, with …

The Europeanization Of Political Parties: A Study Of Political Parties In Poland 2009-2014, Dennis Jan Blew

Dissertations and Theses

On May 1^st 2004, Poland entered the European Union (EU), introducing new variables into the domestic politics of the Polish Republic. Since gaining its independence from Soviet control in 1989, Poland’s political landscape can be described as a dynamic and ever changing force towards democratic maturation. With the accession of Poland to the EU, questions of European integration and Europeanization have arisen, most specifically with how these two processes effect and shape the behaviors of domestic political actors.

With Poland entering its second decade of EU membership, this study attempts to explain how, and if, further European integration has …

An Exploration Of Bicyclist Comfort Levels Utilizing Crowdsourced Data, Bryan Philip Blanc

Dissertations and Theses

Bicycle transportation has become a central priority of urban areas invested in improving sustainability, livability, and public health outcomes. Transportation agencies are striving to increase the comfort of their bicycle networks to improve the experience of existing cyclists and to attract new cyclists. The Oregon Department of Transportation sponsored the development of ORcycle, a smartphone application designed to collect cyclist travel, comfort, and safety information throughout Oregon. The sample resulting from the initial deployment of the application between November 2014 and March 2015 is described and analyzed within this thesis. 616 bicycle trips from 148 unique users were geo-matched to …

This study is a gendered analysis of natural resource management at the local scale of a poor rural Sri Lankan village in a conservation buffer zone. This village experiences destruction of forests and human elephant conflict. The objective of this study is to gain an in-depth knowledge of residents' use and understandings of environmental resources, and to investigate if gender helps shape these factors. This study relies on a social sustainability conceptual framework. It tracks participation of local women and men in natural resource management, and in conservation within and outside of the Bibile community. Local nongovernmental organizations focus on …

Language Policy And Bilingual Education For Immigrant Students At Public Schools In Japan, Naomi Asakura

Dissertations and Theses

This thesis discusses the current Japanese language (nihongo) education for immigrant students at public schools in Japan and provides recommendations through the study of language policy and the comparison of bilingual education in the United States. The current situation of a decreasing birth rate and increasing aging population in Japan has led to the acceptance of more foreign workers. Due to this change, language education in Japan has increasing development. The focus of chapter 1 is on the theories of language policy. This paper particularly focuses on the ideas of Wright (2004), Neustupný (2006), Spolsky (2004), and Cooper (1989), and …

Inspiring Action: Measuring The Effect Of Motivational Frames On Social Movement Mobilization, Rebecca Louise Smith

Dissertations and Theses

In order to probe how social movement messages foster participant mobilization, this study utilized an experimental design to investigate collective action frames, core messaging tasks that define problems, assign blame, convey a plan of action, and inspire participation. The study compared the effects of climate change messages that contain motivational frames with those that do not, incorporating the influence of resonance, and exposure to competing and counter frames. Results revealed that motivational frames contributed to mobilization, especially intention to act, under conditions of resonance and with exposure to counter frames. Salience primed participants to respond to motivational frames, however for …

Supervisor-Specific Outcomes Of A Work-Family Intervention: Evidence From The Work, Family, & Health Study, Mackenna Laine Perry

Dissertations and Theses

Workplace interventions provide a practical and important means of providing support for employees' work-family needs. However, work-family interventions are rare and are generally not thoroughly evaluated. The current study seeks to better understand the impacts of STAR ("Support. Transform. Achieve. Results."), the large-scale work-family intervention developed and implemented by the Work, Family, & Health Network (see Bray et al., 2013). Drawing on Conservation of Resources theory (Hobfoll, 1989), this study examines supervisors' participation in STAR through assessment of three primary supervisor-specific outcomes: training-related views and behaviors, well-being, and the work-family interface. The sample, consisting of 184 supervisors from 30 extended-care …

Training "In A Good Way": Evaluating The Effect Of A Culturally Responsive Pre-Training Intervention On Learning And Motivation, Adam Thomas Murry

Dissertations and Theses

Employee Training and Development (T&D) is a crucial component to an organization’s success and its ability to remain competitive. Although researchers in the field have discovered ways to enhance the effectiveness of training programs through the design, delivery, and evaluation process, research has not provided empirically-based recommendations for how to best train individuals whose cultural backgrounds may influence receptiveness of training curriculum. This is particularly relevant for employees whose cultural groups have been historically discriminated against, where cultural norms implicit in the training design may be met with resistance on behalf of the trainees. In the field of multicultural education, …

Assessing The Impact Of Restrictiveness And Placement Type On Transition-Related Outcomes For Youth With And Without Disabilities Aging Out Of Foster Care, Jessica Danielle Schmidt

Dissertations and Theses

Nearly 23,000 youth age out of the foster care system between the ages of 18 and 21 each year in a transition fraught with challenges and barriers. These young people often lack developmentally appropriate experiences and exposure to necessary knowledge, role modeling, skill building, and long-term social support to promote positive transitions to adulthood while in foster care. As a result, young people who exit care face an array of poor adult outcomes. Nearly 60% of transition-aged foster youth experience a disability, and as such, face compounded challenges exiting foster care. While the examination of young adult outcomes for youth …

A Queer Liberation Movement? A Qualitative Content Analysis Of Queer Liberation Organizations, Investigating Whether They Are Building A Separate Social Movement, Joseph Nicholas Defilippis

Dissertations and Theses

In the last forty years, U.S. national and statewide LGBT organizations, in pursuit of "equality" through a limited and focused agenda, have made remarkably swift progress moving that agenda forward. However, their agenda has been frequently criticized as prioritizing the interests of White, middle-class gay men and lesbians and ignoring the needs of other LGBT people. In their shadows have emerged numerous grassroots organizations led by queer people of color, transgender people, and low-income LGBT people. These "queer liberation" groups have often been viewed as the left wing of the GRM, but have not been extensively studied. My research investigated …

Caring For The Land, Serving People: Creating A Multicultural Forest Service In The Civil Rights Era, Donna Lynn Sinclair

Dissertations and Theses

This qualitative study of representative bureaucracy examines the extension and limitations of liberal democratic rights by connecting environmental and social history with policy, individual decision making, gender, race, and class in American history. It documents major cultural shifts in a homogeneous patriarchal organization, constraints, advancement, and the historical agency of women and minorities. "Creating a Multicultural Forest Service" identifies a relationship between natural and human resources and tells a story of expanding and contracting civil liberties that shifted over time from women and people of color to include the differently-abled and LGBT communities. It includes oral history as a key …

Mistrust: An Exploration Of African Americans' Attitudes And Perspectives Toward Healthcare, Adolfo Gabriel Cuevas

Dissertations and Theses

This dissertation explored mistrust through focus group discussions (study 1), responses to standardized laboratory vignettes (study 2), and survey questionnaires (study 3). In the first study, I found that African American community members (N=60) experienced perceived discrimination, medical mistrust, and poor communication in numerous and interrelated ways. For example, medical mistrust occurred when clinicians did not convey respect to patients, leaving patients to wonder whether their clinician's treatment was discriminatory or not. Based on these findings, I wanted to see whether these experiences of perceived discrimination and mistrust were related to other dimensions of Black experience, such as racial identity. …

Network Structure, Network Flows And The Phenomenon Of Influence In Online Social Networks: An Exploratory Empirical Study Of Twitter Conversations About Youtube Product Categories, Nitin Venkat Mayande

Dissertations and Theses

Traditional marketing models are swiftly being upended by the advent of online social networks. Yet, practicing firms that are engaging with online social networks neither have a reliable theory nor sufficient practical experience to make sense of the phenomenon. Extant theory in particular is based on observations of the real world, and may thus not apply to online social networks. Practicing firms may consequently be misallocating a large amount of resources, simply because they do not know how the online social networks with which they interact are organized.

The purpose of this dissertation is to investigate how online social networks …

Investigating The Impact Of Sibling Foster Care On Placement Stability, Jeffrey David Waid

Dissertations and Theses

Sibling relationships are an important, yet under investigated aspect of foster care research. Despite the fact that between 65-85% of children in care have brothers and sisters, only recently have child welfare researchers begun to explore the complex and dynamic nature of sibling relationships in substitute care settings. Although cross-sectional and longitudinal studies suggest differences in placement stability and permanency outcomes for siblings placed together versus those placed separately, the conditions under which sibling relationships influence placement stability, permanency, and well-being in foster care settings remain unknown.

This dissertation investigated how family dynamics and home setting characteristics influenced the likelihood …

An Examination Of Factors That Catalyze Lgbtq Movements In Middle Eastern And North African Authoritarian Regimes, Michael Anthony Figueredo

Dissertations and Theses

Citizens' increased access to the internet is transforming political landscapes across the globe. The implications for civil society, culture, religion, governmental legitimacy and accountability are vast. In nations where one does not typically expect "modern" or egalitarian ideals to be prevalent among highly religious and conservative populations, those with motivations to unite around socially and culturally taboo causes are no longer forced to silently acquiesce and accept the status quo. The internet has proven to be an invaluable tool for those aiming to engage in social activism, as it allows citizens in highly oppressive authoritarian regimes to covertly mobilize and …

Pseudocapacitors For Energy Storage, Anuradha Venkataraman

Dissertations and Theses

Fluctuation in the demand for electrical power and the intermittent nature of the supply of energy from renewable sources like solar and wind have made the need for energy storage a dire necessity. Current storage technologies like batteries and supercapacitors fall short either in terms of power output or in their ability to store sufficient energy. Pseudocapacitors combine features of both and offer an alternative to stabilize the power supply. They possess high rates of charge and discharge and are capable of storing much more energy in comparison to a supercapacitor. In the quest for solutions that are economical and …

Jews, Sports, Gender, And The Rose City : An Analysis Of Jewish Involvement With Athletics In Portland, Oregon, 1900-1940, Kelli Ann Tusow

Dissertations and Theses

The subject of Jews in sports is often times perceived as an oxymoronic research topic given the ethnic stereotypes that Jews are physically weak, unfit, and more focused on intellectual pursuits. However, Jews have had a long history and in-depth interaction with sports that is important to understand, not only to expand our perception of the Jewish people, but also to realize the important role sports play in social historiography. While the Jewish population of East Coast America and their involvement in athletics has been studied to some extent, the West Coast population, in particular, the Northwest, has been sorely …

The Multilevel Effects Of Supervisor Adaptability On Training Effectiveness And Employee Job Satisfaction, Joseph Alvin Sherwood

Dissertations and Theses

The present study explored the multilevel effects of supervisor learning adaptability on training effectiveness, and post-training employee job satisfaction in a work-family and safety-based intervention aimed at increasing family supportive supervisor behaviors (FSSB) and safety behaviors. Using a sample of 291 municipal public works field workers from two independent organizations, it was hypothesized that supervisor adaptability positively relates to post-training FSSB and employee job satisfaction. Specifically, it was hypothesized that learning adaptability prepares those supervisors to be more inclined to engage actively in training, thereby increasing employee reported FSSBs more significantly for those supervisors and leading to intervention target results, …

Therapy And The Nontraditional Transgender Narrative, Dylan Ellingson Waller

Dissertations and Theses

The history of transgender identity is inextricable from the mental health industry. Since the late 1970's transgender people have required permission from mental health professionals to make medical modifications to their sex characteristics. During the time of this research, it was difficult for transgender individuals to receive the hormones or surgeries they desire without first being diagnosed with Gender Identity Disorder (GID).

This study applies labeling theory to the label of GID. Labeling theory poses that if an individual is labeled with a mental illness, they will either reject or accept the label. Acceptance of the mentally ill label will …

Nationalism In United States Foreign Policy In The Post 9/11 Era, Chris W. Baum

Dissertations and Theses

One year after the terror attacks of September 11, 2001, the administration of President George W. Bush introduced a revolutionary foreign policy strategy--the Bush Doctrine. Proponents of this strategy advocated the use of American 'hard power' as a tool to promote freedom and democracy, beginning with the invasions of Afghanistan and Iraq. Opponents of the doctrine saw it as dangerously nationalistic, with the potential to entangle the United States in a myriad of protracted international conflicts. This thesis will identify aspects of nationalism within post-9/11 American foreign policy and illuminate the incompatibility of nationalism and the fundamental tenets of conflict …
