Affordances On Facebook, Stress, And Emotional Support, Caitlin Rose Rethwish

Dissertations and Theses

This study discusses Facebook as a social network site and a social media application. It compares perceived emotional support, general life stress, and media affordance-based stress from two participant samples - one that reported using the Facebook desktop site most frequently to reach out for emotional support, and one that reported using the mobile application.

The media affordance measure asked participants if perceiving a media affordance was more likely to increase or decrease their stress. In both samples, persistence was more likely to decrease stress, and personalization was more likely to increase stress. On the Facebook Desktop site, searchability was …

Consciousness Against Commodifcation: The Potential For A Radical Housing Movement In The Cully Neighborhood, Cameron Hart Herrington

Dissertations and Theses

A right to housing is a central iteration of the broader demand for a democratic right to the city. The perpetual housing crisis for lower-income people results from a commodified system in which access to housing is based on the exchange value interests of property owners, rather than a universal right to a decent, affordable home. This system is a pillar of neoliberal urban governance and justified by a hegemonic ideology that equates speculative homeownership with the American Dream. Achieving a right to housing, even at the local scale, requires a radical movement that cultivates individual and collective consciousness, discredits …

Long-Term Variation Of Summer Phytoplankton Communities In An Urban Lake In Relation To Lake Management And Climate Conditions, Yuan Xiao Grund

Dissertations and Theses

Eutrophication is one of the primary factors causing harmful cyanobacteria blooms in freshwater lakes; climate change such as warmer temperature can potentially further increase both frequency and intensity of blooms. This study investigated the long-term changes in water quality and summer phytoplankton assemblages in Oswego Lake, OR, in relation to lake management practices (e.g., hypolimnetic aeration and alum treatments), as well as climatic and regional meteorological conditions. Both water quality and phytoplankton assemblages were sampled biweekly during summer seasons between 2001 and 2013. The concentrations of total phosphorus (TP), soluble reactive phosphorus (SRP) and total nitrogen (TN) decreased 66%, 93% …

Lone Wolves And Copycats: Assessing Policy And Infrastructure For Flood Hazard And Floodplain Management, Samantha L. Hamlin

Dissertations and Theses

To mitigate flood hazard, which affects millions of people every year, increasing numbers of communities are developing green infrastructure policies to not only mitigate the hazard, but to meet other community policy objectives, as green infrastructure is often cited for the multiple benefits it confers. To support the implementation of policies that help communities meet their policy objectives, however, it is imperative to understand how policy is innovated and adopted. To do so, I applied the internal determinants and regional diffusion models, what I refer to as the lone wolf and copycat models. In policy, a lone wolf innovates a …

Characterizing Temperature Variability States Across Southern South America And Associated Synoptic-Scale Meteorological Patterns, Judah Adam Detzer

Dissertations and Theses

The aim of this thesis is to understand spatiotemporal temperature variability in southern South America by identifying overarching temperature variability states and their associated synoptic-scale meteorological patterns. Further, the temporal frequency of occurrence of those temperature variability states is investigated as is the role of recurrent low-frequency modes of climate variability (El Niño Southern Oscillation and the Southern Annular Mode) on temperature variability. K-means cluster analysis is used to group all months during the period 1980-2015 into four primary categories for summer and winter separately. Monthly maps of temperature anomalies are provided as input to the k-means algorithm and the …

Age-Based Differences In The Usefulness Of Resources: A Multi-Study Investigation Of Work And Well-Being Outcomes, Lale Muazzez Yaldiz

Dissertations and Theses

The labor force is aging globally. It is projected that the number of older workers will increase in the workforce in the near future. At the same time, it is estimated that workplaces will grow more age-diverse, where younger and older workers will work side-by-side more often than they used to. These demographic shifts in the workforce necessitate a further understanding of the differences between the values, needs and motivation, and work outcomes of employees of different ages. To this end, few studies to date have investigated whether job-related resources are differentially useful for the work and non-work outcomes of …

The Role Of The Academic Analyst In Shared Governance, Rebecca Ann Mathern

Dissertations and Theses

This research explores the roles of academic professionals in higher education, specific to how they engage in decision-making processes. Academic professionals provide important functions in higher education work but there is little in the literature about these actors and their contributions to leadership and governance. A literature review triangulated role theory, organization theory, and the shared-governance field of study to bring together actors within higher education and compare their involvement based on the shared-governance model in operation at different institutions. The researcher introduced the hypothesis that when registrars are not involved in curriculum management, there may be negative effects on …

Investigating Time During Residential Program Until Transition For Adjudicated Youth: A Mixed Methods Study Using Event History Analysis With Follow-Up Interviews, Emily Carol Lott

Dissertations and Theses

Residential placement is considered the most severe sanction for adjudicated youth, yet there is little consensus on best practices and interventions in residential settings. Demographic trends in the juvenile justice system further exacerbate challenges in studying residential placements. Disparities among minority youth, diverging state definitions of juvenile sex offenses, discrepancies in recidivism measures, and variations in local and state juvenile courts have contributed to a convoluted system that has struggled to identify the meaning of "success" in residential settings.

Building on theories of engagement in residential care and program theory of change, this mixed methods study explores how various components …

Studying The Effects Of Motivated Reasoning On Appraisals Of Message Strength, Aric Christopher Powell

Dissertations and Theses

This study was designed to investigate decision-making as it relates to message appraisal, and determine what effect, if any, identification with the message source has on those appraisals. For the purpose of study, message appraisal was operationalized as message strength ratings. Furthermore, the study investigated how the political ideology of message receivers and the perceived partisanship of message senders might influence identification, and message appraisal by extension. The study used the theory of motivated reasoning to explain the role of identification in the process of message appraisal. The results indicate that there is a relationship between identification and message strength …

Judgments Of Lethal Risk: A Comparison Of Visual And Narrative Stimuli, Derek Anthony Bonniksen

Dissertations and Theses

The nature of how we make judgments has received a great deal of attention in the last few decades. Risk communication research has indicated that risk-related messages can elicit affective responses in audiences, which can then have a significant impact on how such audiences judge risk in general. Using a 2 x 2 between-subjects factorial design, this study found that, contrary to Johnson and Tversky's (1983) findings, presenting narratives about lethal risk does not influence readers' judgments about the frequency that risks occur, nor do such narratives influence participant worry levels about the lethal risks, more generally. Additionally, the inclusion …

Assessing Ppgis Usability And Its Relationship To Spatial Data Production: A Case Study, Timothy Michael Hitchins

Dissertations and Theses

Modern Geoweb-enabled PPGIS methodologies incorporate interactive map applications as the main driver for public engagement and data collection. However, little research explores exactly how the public interact with these applications to produce spatial data, a fact that contributes to criticisms of final data quality. Usability evaluation offers a solution for developing better PPGIS data production systems by identifying problems in the application interface for which the public engage. Drawing on a case study example of a PPGIS application developed to collect socio-spatial data from members of a random public, this paper addresses usability in a three-stage approach. First, controlled experimentation …

How Can Community Engagement In The Local Past And Archaeological Research Be Mutually Beneficial? A Case Study In Community Archaeology From Sauvie Island, Oregon, Martin John Plumer

Dissertations and Theses

Community archaeology's broader objectives include increasing public understanding of archaeology and making archaeology more relevant to people's day to day lives. Fulfilling these goals could be beneficial to the public in terms of their gaining more agency in, and more access to, archaeology; and it could be beneficial to archaeologists in terms of increasing public support for archaeological work. While many community archaeologists report success, few authors critically evaluate the experience and outcomes of community archaeology. As a result, little data-based understanding exists about what is gained through community archaeology. This project explores that question through three primary means: 1) …

"My Teacher Says I'M An Overachiever, But I Think He's An Overexpecter" : Teacher Expectations, Self-Concept, And Academic Success, Jennifer Lea Campbell

Dissertations and Theses

This study explores the relationship between student judgments of teacher expectations and academic success, student self-concept and academic success, and student judgments of discrimination experiences and academic success. In the winter of 2018, a sample of 176 communication students at a northwestern university completed revised versions of the Teacher Treatment Inventory (TTI) and the Self-Description Questionnaire III (SDQ III), as well as the original Everyday Discrimination Scale (EDS). College-age students found the TTI confusing, and many participants said they did not have a relationship with their college professors. The hypothesis that suggested student judgments of teacher expectations would positively correlate …

Examining The Spatial Characteristics Of Pluvial Flooding Through Citizen Science In Portland, Oregon, Katelyn Rachel Michelson

Dissertations and Theses

Pluvial flooding is caused by rainfall events that overwhelm drainage systems and do not allow excess water to be absorbed by soils or water infrastructure. This type of flooding occurs frequently in urban systems and leads to public inconveniences and infrastructure deterioration, which could cost more than fluvial flooding over time. Increased rainfall intensity, which is projected to increase with climate change, could result in increased pluvial flooding. This study aims to examine the vulnerability of pluvial flooding in Portland, OR (2010-2017) by incorporating an interdisciplinary framework that examines the physical and socioeconomic vulnerability of flooding through citizen-reported flooding data. …

My research seeks to identify the place meanings that underpin sense of place, place attachment, and processes of attachment formation, among residents of the neighborhood. My research questions are: What are the objects of attachment? Why (the place meanings that underpin attachment)? And how (through what processes are attachments formed)? In what ways are the "why" and …

The Impact Of Leader Race And Gender On Perceptions Of Organizations In Response To Corporate Error, Nicolas Derek Brown

Dissertations and Theses

Prior research has demonstrated that CEO behavior influences how people perceive corporations and that CEOs associated with controversy can damage corporate reputations. Research also illustrates that attitudes based on prescribed racial and gender characteristics render Black and female CEOs as incongruent with leadership positions. The purpose of this study is to examine the impact of two different corporate errors as justification factors leading to prejudicial evaluations of leaders with stigmatized identities (e.g., race and gender), with a particular emphasis on the intersection of race and gender on leader- and organization-based evaluations. Participants were randomly assigned to one of 12 corporate …

Removing Dams, Constructing Science: Watershed Restoration Through A Socio-Eco-Technical Systems Lens, Zbigniew Jakub Grabowski

Dissertations and Theses

Ecological conservation and restoration in the anthropocene must struggle with overlapping drivers of biodiversity and cultural loss; ruptures of the ecological environment mirror ruptures of human relationships with nature. And yet technology cannot remove humans from nature; technological and infrastructural reconfigurations of nature create new vulnerabilities and risks for humans and ecosystems alike. How can conservation and restoration science productively grapple with complex infrastructure systems and decision-making processes as biophysical and social drivers of ecosystem change?

Using dam removals in the USA and in the Mid Columbia River region of the Pacific Northwest, this dissertation develops a conceptual framework for …

Developing A Mixed-Methods Method To Model Elderly Health Technology Adoption With Fuzzy Cognitive Map, And Its Application In Adoption Of Remote Health Monitoring Technologies By Elderly Women, Noshad Rahimi

Dissertations and Theses

Providing healthcare to the ever-rising elderly population has become a severe challenge and a top priority. Emerging innovations in healthcare, such as remote health monitoring technologies, promise to provide a better quality of care and reduce the cost of healthcare. However, many elderly people reject healthcare innovations. This lack of adoption constitutes a big practical problem because it keeps the elderly from benefiting from technology advances. The phenomenon is even more pronounced among elderly women, who represent the majority of the elderly population.

A plethora of studies in the field of technology adoption resulted in sound, but highly generalized theories …

Inclusion And Assimilation: Including Change In The Workplace, Marisa Jean Miller

Dissertations and Theses

Organizational assimilation is an ongoing and dynamic relationship between organization and individual member, where employees learn the expected norms of the organization and feel that they are able to attempt to make a change to the organization. Organizational members rely on social interactions within the organization to acquire the necessary knowledge they need to perform their roles, as well as support to attempt changes within the organization. This study proposes that feelings of inclusion, or the perception that an employee both belongs to and is unique within an organization, may be an influential construct associated with organizational assimilation and beneficial …

Selling Protest In The News? Movement-Media Framing Of Occupations: An Exploratory Study, Andrew David Butz

Dissertations and Theses

Using quantitative content analysis, this study explores social movement (SM) framing in commercial news media -- by comparing how leading newspapers covered prominent protest occupations in 2011 and 2016. More than other SMs, anti-systemic protests like the 2011 Occupy Wall Street (OWS) and the 2016 Malheur Refuge Occupation (MRO) only have partial frame-setting agency, raising a broad theory question (to inform the research questions below): If SMs and media relate as interacting systems, are protest news frames more movement- or more media- driven; and do media not just enable but also constrain SMs?

With the movement-media theory question above, the …

Bystander Intervention To Prevent Campus Sexual Violence: The Role Of Sense Of Community, Peer Norms, And Administrative Responding, Erin Christine Mcconnell

Dissertations and Theses

In recent years, the use of bystander intervention training to address campus sexual violence has risen rapidly. More research is critically needed to guide the ongoing development and implementation of prevention efforts by campuses utilizing this relatively new approach. This investigation examined associations between college students' bystander intervention behavior and three key factors: (1) perceived peer norms supportive of sexual violence; (2) perceived campus administrative response to sexual violence; and (3) sense of campus community. Data from a sample of 2370 college students was analyzed using hierarchical linear regression to test both direct and moderated effects. Findings revealed that both …

White Space, Black Space: Community Gardens In Portland, Oregon, David Ross Billings Jr.

Dissertations and Theses

Community gardens have been the focus of social science research in the United States for several decades and the benefits associated with these alternative food spaces has been well documented. More recently, scholars have begun to argue that these benefits are inequitably distributed across society. Largely as a result of the whiteness of these spaces, people of color are less represented in community and benefit less from their presence. Portland, Oregon is recognized as a leader in sustainability, with its abundance of community gardens and urban agriculture. It is also one of the whitest urban cities in the United States. …
