Affordances On Facebook, Stress, And Emotional Support, Caitlin Rose Rethwish Dec 2018

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 more ...


Consciousness Against Commodifcation: The Potential For A Radical Housing Movement In The Cully Neighborhood, Cameron Hart Herrington Dec 2018

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 Dec 2018

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 ...


Characterizing Temperature Variability States Across Southern South America And Associated Synoptic-Scale Meteorological Patterns, Judah Adam Detzer Dec 2018

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 ...


The Role Of The Academic Analyst In Shared Governance, Rebecca Ann Mathern Nov 2018

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 Nov 2018

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 ...


Judgments Of Lethal Risk: A Comparison Of Visual And Narrative Stimuli, Derek Anthony Bonniksen Nov 2018

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 ...


Studying The Effects Of Motivated Reasoning On Appraisals Of Message Strength, Aric Christopher Powell Nov 2018

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 ...


Assessing Ppgis Usability And Its Relationship To Spatial Data Production: A Case Study, Timothy Michael Hitchins Sep 2018

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 Aug 2018

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 ...


"My Teacher Says I'M An Overachiever, But I Think He's An Overexpecter" : Teacher Expectations, Self-Concept, And Academic Success, Jennifer Lea Campbell Aug 2018

"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 Aug 2018

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 ...


Our Town: Articulating Place Meanings And Attachments In St. Johns Using Resident-Employed Photography, Lauren Elizabeth Morrow Everett Aug 2018

Our Town: Articulating Place Meanings And Attachments In St. Johns Using Resident-Employed Photography, Lauren Elizabeth Morrow Everett

Dissertations and Theses

The St. Johns neighborhood of North Portland is known for its strong regional identity, working class character, and diversity. Portland as a whole has experienced a major socioeconomic shift in the last ten years, and these changes are hitting St. Johns particularly hard. 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 Aug 2018

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 ...


Assessing Spatiotemporal Stream Temperature Trends And Drivers Through Integrated Longitudinal Thermal Profiling And Stationary Data Logger Methodology On The Upper Chehalis River, Wa, Whitney Vonada Aug 2018

Assessing Spatiotemporal Stream Temperature Trends And Drivers Through Integrated Longitudinal Thermal Profiling And Stationary Data Logger Methodology On The Upper Chehalis River, Wa, Whitney Vonada

Dissertations and Theses

This study encompasses 25 kilometers of the Chehalis River in Washington, USA that currently has sections under a Total Maximum Daily Load (TMDL) plan for stream temperature impairments that exceed 18°C, a regulatory standard set at the time of the listing to protect salmonid spawning, rearing, and migration. Using information integrated from stationary data loggers (n=22) that collected stream temperature information from August 4-September 10, 2017, and longitudinal thermal profiling performed on July 29-30, August 4-5, and September 9-10, 2017, this study aimed to quantify the spatial distribution of stream temperature, evaluate relative consistencies of the riverine thermal ...


Removing Dams, Constructing Science: Watershed Restoration Through A Socio-Eco-Technical Systems Lens, Zbigniew Jakub Grabowski Aug 2018

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 Aug 2018

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 Aug 2018

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 Jul 2018

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 study ...


White Space, Black Space: Community Gardens In Portland, Oregon, David Ross Billings Jr. Jul 2018

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 ...


Environmental Justice In Natural Disaster Mitigation Policy And Planning: A Case Study Of Flood Risk Management In Johnson Creek, Portland, Oregon, Seong Yun Cho Jul 2018

Environmental Justice In Natural Disaster Mitigation Policy And Planning: A Case Study Of Flood Risk Management In Johnson Creek, Portland, Oregon, Seong Yun Cho

Dissertations and Theses

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 ...


Grammatical Errors By Arabic Esl Students: An Investigation Of L1 Transfer Through Error Analysis, Aisha Saud Alasfour Jul 2018

Grammatical Errors By Arabic Esl Students: An Investigation Of L1 Transfer Through Error Analysis, Aisha Saud Alasfour

Dissertations and Theses

This study investigated the effect of first language (L1) transfer on Arabic ESL learners' acquisition of the relative clauses, the passive voice and the definite article. I used Contrastive Analysis (CA) and Error Analysis (EA) to analyze 50 papers written by Arabic ESL students at the ACTFL Advanced Mid proficiency level. The analysis was paired with interviews with five advanced students to help determine whether L1 transfer was, in fact, influencing students' errors predicted by CA.

Students in this study made L1 errors along with other errors. Although no statistical difference was found between the frequency of transfer and other ...


Bystander Intervention To Prevent Campus Sexual Violence: The Role Of Sense Of Community, Peer Norms, And Administrative Responding, Erin Christine Mcconnell Jul 2018

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 ...


Gendered Partner-Ideals, Relationship Satisfaction, And Intimate Partner Violence, Sylvia Marie Ferguson Kidder Jul 2018

Gendered Partner-Ideals, Relationship Satisfaction, And Intimate Partner Violence, Sylvia Marie Ferguson Kidder

Dissertations and Theses

This dissertation identified and developed indicators of a new potential predictor of relationship satisfaction and intimate partner violence (IPV): discrepancies between the ideal and perceived gendered characteristics of romantic partners. Past research has overlooked the implicitly gendered nature of these "partner-ideals." Two pilot studies were conducted to develop measures of gendered partner-ideals and -perceptions based on existing measures of gender ideology.

The main study examined survey data collected online from adults (n = 643) living in the U.S. who were in a heterosexual romantic relationship for at least six months. Three main hypotheses were tested regarding the associations among gender ...


A Foucaultian Discourse Analysis Of Person-Centered Practice Using A Genealogical Framework Of Intellectual Disability, Nick Winges-Yanez Jul 2018

A Foucaultian Discourse Analysis Of Person-Centered Practice Using A Genealogical Framework Of Intellectual Disability, Nick Winges-Yanez

Dissertations and Theses

A genealogical framework highlights the important role sexuality has played in constructing the current label of intellectual disability (ID). The genealogical framework is meant to replace the social, medical, and/or rights-based model(s) that have dominated social work and social services working in the disability field. With this framework, or perspective, I use a Foucaultian discourse analysis to read through seminal texts regarding person-centered practice.

Person-centered practice is the foremost intervention used in social work, and other disciplines, to work with people labeled with intellectual disability. My research questions focus on what is revealed about ID in PCP through ...


The Intersections Of Good Intentions, Criminality, And Anti-Carceral Feminist Logic: A Qualitative Study That Explores Sex Trades Content In Social Work Education, Meg Rose Panichelli Jul 2018

The Intersections Of Good Intentions, Criminality, And Anti-Carceral Feminist Logic: A Qualitative Study That Explores Sex Trades Content In Social Work Education, Meg Rose Panichelli

Dissertations and Theses

This study uses anti-carceral feminist logic to explore the cultural meanings, criminal implications, and neoliberal influence that shape the landscape of social work education about the sex trades in the United States and transnationally. "What are social work instructors teaching students about the sex trades in coursework?" is the question that directs the study, which uses a feminist qualitative methodology inclusive of intersectional feminist epistemology as well as direct content analysis. To answer this question, I analyzed 20 social work course syllabi from sex trade related courses across the contiguous United States and interviewed 20 social work instructors from 14 ...


Intrapersonal And Social-Contextual Factors Related To Psychological Well-Being Among Youth Experiencing Homelessness, Katricia Stewart Jul 2018

Intrapersonal And Social-Contextual Factors Related To Psychological Well-Being Among Youth Experiencing Homelessness, Katricia Stewart

Dissertations and Theses

Homeless youth are typically defined as a group of adolescents and young adults (ages 12-24) who do not have stable dwellings, but instead live on the streets, in shelters or abandoned buildings, or in other unstable situations (e.g., doubling up with friends). Given the myriad of hardships, stressors, and marginalization faced by youth as they navigate life on the streets, it is encouraging that researchers have begun examining well-being among youth experiencing homelessness. However, the few studies examining well-being among homeless youth have produced inconsistent results. Furthermore, little is known about the components of well-being that are both relevant ...


Between A Rock And A Hot Place: Economic Development And Climate Change Adaptation In Vietnam, Khanh Katherine Pham Jul 2018

Between A Rock And A Hot Place: Economic Development And Climate Change Adaptation In Vietnam, Khanh Katherine Pham

Dissertations and Theses

This thesis explores 1) the ways that three Vietnamese infrastructure development projects undermine their cities' climate change adaptation goals and 2) the political and economic forces driving these developments. In-depth interviews highlight four main perspectives of planners and decision makers, which explain why these infrastructure projects often undermine cities' climate resilience goals. I describe how the mainstream climate change adaptation planning approach, with its emphasis on participatory planning, good governance and green growth, implicitly reinforces the neoliberal growth model, even as it seeks to ameliorate the inequality and ecological destruction that such a growth model creates. My research reveals how ...


Stance-Taking: Jfl Learners And Benefactive Verbs, Kumiko Takizawa Jul 2018

Stance-Taking: Jfl Learners And Benefactive Verbs, Kumiko Takizawa

Dissertations and Theses

This study explores how JFL learners take a benefactive stance in Japanese. As Jaffe (2009) observes, stance-taking "plays a complex role with respect to the naturalization of social and linguistic ideologies and the social structures they legitimate." The way in which language is used to take a stance always concerns the social context in which a speaker finds her/himself. In Japanese, benefactive verbs (kureru, ageru, morau and their honorific and humble equivalents) are indispensable stance indicators for showing gratitude or indebtedness. Such expressions do not really exist in English and their grammar is complex. It is assumed that JFL ...


Insufficient Effort Responding On Mturk Surveys: Evidence-Based Quality Control For Organizational Research, Lee Cyr Jul 2018

Insufficient Effort Responding On Mturk Surveys: Evidence-Based Quality Control For Organizational Research, Lee Cyr

Dissertations and Theses

Each year, crowdsourcing organizational research grows increasingly popular. However, this source of sampling receives much scrutiny focused on data quality and related research methods. Specific to the present research, survey attentiveness poses a unique dilemma. Research on updated conceptualizations of attentiveness--insufficient effort responding (IER)--shows that it carries substantial concerns for data quality beyond random noise, which further warrants deleting inattentive participants. However, personal characteristics predict IER, so deleting data may cause sampling bias. Therefore, preventing IER becomes paramount, but research seems to ignore whether IER prevention itself may create systematic error. This study examines the detection and prevention of ...
