Differentiation And Diffusion: Shifting Public Opinion Attitudes Toward Foreign Policy In North Africa, Lindsay J. Benstead

Political Science Faculty Publications and Presentations

Drawing on Arab Barometer data, this article provides the backdrop for understanding continuity and change since the Arab Spring in national-level public opinion attitudes toward economic and political foreign policy issues in North Africa, inclusive of Algeria, Egypt, Libya, Morocco, and Tunisia. The article leverages the concepts of differentiation and diffusion to understand how international affairs shape public opinion in North Africa since the Arab Spring. Three findings emerge. First, public opinion about domestic and international issues are linked in the minds of North African citizens and foreign policy issues are more important factors underlying pre- and post-Arab Spring politics …

Social-Transportation Analytic Toolbox (Stat) For Transit Networks, Xiaoyue Cathy Liu, Qian Zuo, Shenruoyang Na, Ran Wei, Aaron Golub, Liming Wang, Jake Davis

TREC Final Reports

This project builds an open-source, socio-transportation analytic (STAT) toolbox for public transit system planning in an effort to integrate social media and general transit feed specification (GTFS) data for transit agencies in evaluating and enhancing the performance of public transit systems. This toolbox is novel and essential to transit agencies in two aspects. First, it enables the integration, analysis and visualization of two major, new open transportation data, social media and GTFS data, to support transit decision-making. Second, it allows transit agencies to evaluate service network efficiency and access equity of transit systems in a cohesive manner, and identify areas …

The Impact Of Framing On Acceptance Of Cultured Meat, Christopher Bryant, Courtney Dillard

University Studies Faculty Publications and Presentations

Cultured meat can be produced from growing animal cells in-vitro rather than as part of a living animal. This technology has the potential to address several of the major ethical, environmental, and public health concerns associated with conventional meat production. However, research has highlighted some consumer uncertainty regarding the concept. Although several studies have examined the media coverage of this new food technology, research linking different frames to differences in consumer attitudes is lacking. In an experimental study, we expose U.S. adults (n = 480) to one of three different frames on cultured meat: “societal benefits,” “high tech,” and “same …

Leveraging Twitter And Machine Learning For Real-Time Transit Network Evaluation, Xiaoyue Cathy Liu, Qian Zuo, Shenruoyang Na, Ran Wei, Aaron Golub, Liming Wang, Jake Davis

TREC Project Briefs

With today’s profusion of open data sources and real-time feeds, transit agencies have an unparalleled opportunity to leverage large amounts of data to improve transit service. Thanks to NITC researchers, there is now an open-source tool for that.

The new Social-Transportation Analytic Toolbox (STAT) for Transit Networks, developed by researchers at the University of Utah and Portland State University, is a dynamic platform that combines Twitter, general transit feed specification (GTFS), and census transportation planning products (CTPP)—in this case, job density data—to help agencies evaluate overall system performance and identify connectivity gaps. It can also act as a decision support …

Multiwavelength Digital Holographic Imaging And Phase Unwrapping Of Protozoa Using Custom Fiji Plug-Ins, David Cohoe, Iulia Hanczarek, J. Kent Wallace, Jay Nadeau

Physics Faculty Publications and Presentations

Multiwavelength digital holographic microscopy (DHM) has been used to improve phase reconstructions of digital holograms by reducing 2p phase ambiguities. However, most samples used as test images have been solid or adhered to a surface, making it easy to determine focal planes and correct for chromatic aberration. In this study we apply 3-wavelength off-axis DHM to swimming protozoa containing distinct spectral features such as chlorophyll and carotenoids. We reconstruct the holograms into amplitude and phase images using the angular spectrum method. Methods for noise subtraction, chromatic aberration correction, and image registration are presented for both amplitude and phase. Approaches to …

Spatial Analysis Of Burglary And Robbery Crime Concentration Near Mass-Transit In Portland, Bryce Edward Barthuly

Dissertations and Theses

The relationship between mass-transit and the concentration of burglary and robbery crimes is inconsistent within the available literature in environmental criminology. A number of studies have provided evidence of crime concentration at and near mass transit locations where paths intersect, referred to as a node. These empirical studies bring in environmental criminology theory with the idea that crime is clustered, and the pattern of the concentrations is substantially influenced by how and why people travel and move in a city. It is suggested that public transit allows for a large proportion of the population to move around the community along …

Parasocial Relationships With Podcast Hosts, Mikhaela Nadora

University Honors Theses

This study is a deductive thematic analysis of podcast hosts' attributes that explores how parasocial relationships (PSR) might be cultivated with listeners. The author analyzes five episodes of a podcast, Stuff You Should Know, and use its transcriptions to code for themes of identification, conversation practices, and authenticity to suggest ways PSR is developed by the podcast's hosts.

Results found host behaviors suggest how listeners may react to them. The combination of the effect of social deixis while describing personal characteristics suggest listeners may feel physically and emotionally closer to the hosts. Listeners may also see them as more trustworthy …

Convivial Clothing: Engagement With Decommodified Fashion In Portland, Or, Sarah Guldenbrein

Dissertations and Theses

In a capitalist system demanding perpetual accumulation, producers invest significant resources into proving the superiority of new products over existing ones. When the normative concept is "better" rather than "good" consumers can never reach a sense of sufficiency. One countermovement is that of degrowth. Degrowth scholars advocate for a voluntary and democratic transition to a post-growth future. This thesis contributes to the emerging literature on degrowth by examining alternatives to "fast fashion," an industry with a huge environmental impact and notoriously high turnover. Drawing on participant observation and semi-structured interviews with participants in Portland, Oregon's clothing swaps and Repair …

Politics In The San Clemente Dam Removal, Aylan Matthew Lee

Dissertations and Theses

This study examines the role of politics in the removal of the 106-foot tall San Clemente Dam. The removal project and negotiations provide a case study of the contemporary phenomenon of dam removal. My analysis joins a growing body of social science literature on the social, political, and human dimensions of removal. The San Clemente Dam, which impounded the Carmel River near Monterey, California, was removed in 2015, the largest such project completed in California. Drawing on political ecology and science and technology studies, and using a mixed qualitative approach, I assess both the role of politics in shaping the …

Characterizing Tilt Effects On Wind Plants, Ryan Scott

Dissertations and Theses

Tilting the nacelle of a wind turbine modifies entrainment into the wind plant and impacts total efficiency. Extreme angles can produce flying and crashing wakes where the wake either disrupts entertainment from the undisturbed flow above or is decimated on the ground. The effect of tilt angle on downstream wake behavior was investigated in a series of wind tunnel experiments. Scale model turbines with a hub height and diameter of 12 cm were arranged in a Cartesian array comprised of four rows of three turbines each. Nacelle tilt was varied in the third row from -15° to 15° in chosen …

Do Female Local Councilors Improve Women’S Representation?, Lindsay J. Benstead

Political Science Faculty Publications and Presentations

Tunisia’s 2018 municipal elections, in which a legislated quota was implemented and women won 47 percent of seats, raises questions about whether electing female councilors improves women’s representation in clientelistic settings. Using data from the Local Governance Performance Index (LGPI), an original survey of 3,600 Tunisians conducted in 2015 by the Program on Governance and Local Development (GLD), this article investigates the relationship between local councilors’ gender and women’s access to help with personal or community issues. Three findings emerge. First, male citizens are thirteen percentage points more likely than female citizens to know a local councilor and six percentage …

Attitudes, Behavior, And Archetypes In The Clackamas River Basin: A Model Of Water Customer Analysis And Outreach For Watershed Protection And Conservation, Daniel Close Larson

Dissertations and Theses

Fresh water resources around the globe are under threat of diminishing supply and quality due to rapid population growth, climate change, drought, and waste. This dissertation aims to address the protection of fresh water at the source, the tap, and how water customer attitudes influence protection and conservation using a watershed-wide lens. Using the Clackamas River Watershed which resides within the Portland Metropolitan Area (PMA), I seek to investigate water customer attitudes towards a source water protection program and their willingness to pay to support such an endeavor, attitudes and behaviors that result in household water conservation, and an exploration …

Scenes From The Swale: Investigating Spatial And Temporal Dimensions Of Nitrogen Cycling In Urban Stormwater Bioretention Facilities, Erin Nicole Looper

Dissertations and Theses

Urban development is transforming landscapes at unprecedented rates. Human activities and landscape modifications associated with urbanization extensively increase hydrologic demands and modify natural hydrologic systems; consequently, population growth occurring in urban areas increases pressure on water resources. Urban aquatic ecosystems are vulnerable to impacts associated with increased connectivity with urban surfaces and hydrologic changes that initiate long-term changes in receiving waterbodies. Nitrogen (N) loading from urban and suburban catchments to receiving surface waters can lead to impairment of aquatic ecosystems and is a concern in many cities with water quality issues. To improve urban water quality, cities are increasingly adopting …

Cultivating A Community Of Resilience For Transgender Collegians Through The Practice Of Sustainable Leadership, Beau Gilbert

Leadership for Sustainability Education Comprehensive Papers

Transgender students have always existed in communities of higher education yet are just now beginning to be acknowledged and included within the context of academia. This has primarily led to the development of campus resource centers intended to protect these students and provide safe spaces on campus. While this is a crucial support system for universities to provide, the framework described herein envisions a future where transgender students can practice resilience and feel a sense of belonging anywhere within their college community. Through a comprehensive review of the literature, this paper highlights the need for a sustainable and campus-wide approach …

Physics-Based Signal Processing Methods For Terahertz Non-Destructive Evaluation Of Layered Media, Scott G. Schecklman

Dissertations and Theses

In recent years Terahertz (THz) time domain spectroscopy has emerged as a promising new technology with potential applications in a variety of fields, including industrial manufacturing, security screening and medical imaging. Pulsed THz systems are uniquely suited for non-destructive evaluation (NDE) of the sub-surface layers of dielectric packaging and coating materials, because they provide high dynamic range over a wide bandwidth in the far infrared portion of the electromagnetic spectrum. Often the dielectric materials of the packaging and/or surface coating layers exhibit relatively low loss and abrupt changes in the refractive index at the layer boundaries can be observed as …

A State Of Longing: Perspectives From Nagorno-Karabakh Idps, Isabelle Mcrae

University Honors Theses

Since the ceasefire in 1994, the intractable conflict of Nagorno-Karabakh continues to have a severe impact on security and development in the Caucasus region. Internally displaced Azerbaijanis (IDPs) from Nagorno-Karabakh are one of the main stakeholders in the conflict, and yet little study has addressed the impact of their symbolic values and identity issues vis-à-vis resolution efforts. Accordingly, this thesis focuses on four themes which arose in the author’s ethnographic research in Azerbaijan with internally displaced Azerbaijanis. The paper will address the group’s relation to the land, the framing of kinship and identity, relations with Armenia and the Armenian community, …

Radical Doulas Make "Caring A Political Act": Full-Spectrum Birthwork As Reproductive Justice Activism, Jadee Yvonne Carathers

Dissertations and Theses

This study, based on in-depth interviews with 30 self-identified radical doulas working in the US, describes the radical practices, positionality, and orientation towards reproductive justice that distinguish these care workers from mainstream doulas. Radical doulas provide nonjudgmental support in a full-spectrum of reproductive experiences from menarche to menopause according to the needs of their clients. As non-medically trained care workers, they provide informational, emotional, and physical support during abortion, birth and postpartum, fetal loss, adoption, or surrogacy, enacting individualized skill sets across settings from homes to hospitals and clinics. Radical doulas are paid professionals, but often offer a sliding-scale for …

Development And Validation Of The Workplace Mental Illness Stigma Scale (W-Miss), Nicholas Anthony Smith

Dissertations and Theses

Although 1 in 5 Americans will experience a mental illness at some point, each year people with mental illnesses continue to face high levels of stigmatization and discrimination at work. Recognizing this, many organizational researchers and practitioners have sought to improve workplaces for employees with mental illness through a variety of organizational interventions. Unfortunately, few interventions are thoroughly evaluated. One barrier to evaluating such interventions is the lack of a theoretically meaningful measure of workplace mental illness stigma. In this dissertation, I proposed to develop and evaluate such a measure (the W-MISS) based on Jones, Farina, Hastorf, Markus, Miller, and …

Photoelectrochemical Catalysis Of Hydrogen Peroxide With Tellurium Containing Chromophores, James Eliott Lohman

Dissertations and Theses

Growing concerns over climate change and demand for energy worldwide have made development and implementation of alternative energy sources more necessary than ever. Many of the leading energy alternatives suffer from inconsistent energy production due to fluctuations in availability of natural resources, and the current methods of addressing the issue have tremendous ecological and social ramifications of their own. While fuels like hydrogen gas are providing some promise of relief, the scope of infrastructure changes necessary for implementation and the implicit hazards of the use of such fuels complicate their application as an immediate solution. However, hydrogen peroxide carries far …

"It's All Because I Like The Person That's Teaching Me": Masculinities, Engagement, And Caring Relationships In Secondary Schools, Cristy Lauren Weggelaar

Dissertations and Theses

U.S. schools face a well-documented gender gap within some important educational and social indicators. In the United States, boys and young men are significantly more likely than girls and young women to be diagnosed with a learning disability, leave high school without a diploma, receive failing grades in core classes, and be suspended or expelled from school. This study uses an interpretive research framework to investigate the relationship between this gender gap in education and constructions of masculinity, social and cultural capital, agency, caring and resistance in secondary schools. Data collected through interviews with young men who engaged in acts …

An Investigation Of The Impact Of High School Student Fine Arts Course Accumulation On Mathematics Course Achievement, Daniel Mackin Freeman

Dissertations and Theses

Science, technology, engineering, and mathematics (STEM) educational achievement is vital to economic competitiveness in the United States and abroad. Despite a concerted effort, the US lags well behind many similarly developed nations. Research suggests that the integration of fine arts education into traditional STEM curriculum (STEAM) boosts academic achievement in STEM subjects and closes gaps between low- and high-socioeconomic status students. Justifications for STEAM programs are based, however, on the unexamined assumption, for one, that fine arts courses instill creative and critical thinking skills that can be transferred to STEM subjects. The present study explores the impact of taking fine …

Making Imaginaries: Identity, Value, And Place In The Maker Movement In Detroit And Portland, Stephen Joseph Marotta

Dissertations and Theses

This dissertation explores the maker economy and culture in Detroit, MI and Portland, OR and queries the "Made in Place" branding strategy that relies so heavily on a shared imagination of cities, identities, and values. Bridging the gap between urban economic development, political economy, and affect theory, this dissertation is centrally concerned with how imagination works as a commons and how such "imaginaries" shape each city's milieu of small, entrepreneurial, artisanal producers ("makers"). The constituent elements of "Made in" branding "made" and "place" suggest common understandings of each; this sense of coherence is critical for how value is added to …

Learning From Culturally Specific Programs And Their Impact On Latino Parent Engagement, Analucia Lopezrevoredo

Dissertations and Theses

Latinos are the largest and fastest growing ethnic minority group in the United States. Academically, they are significantly trailing their non-Latino peers in graduation and overall educational attainment. Among many socioeconomic factors, parent engagement has been identified as being a defining indicator of student success. Reflective of racial and class disparities, this study explored with the use of critical race and intersectionality theory, that low Latino parent engagement is a result of the historical devaluing and omission of Latino culture, history and language from formal academic settings, and compounding social factors that make engagement complex for Latino immigrants in America …

E-Cigarette Chemistry And Analytical Detection, Robert M. Strongin

Chemistry Faculty Publications and Presentations

The study of e-cigarette aerosol properties can inform public health while longer-term epidemiological investigations are ongoing. The determination of aerosol levels of known toxins, as well as of molecules with unknown inhalation toxicity profiles, affords specific information for estimating the risks of e-cigarettes and for uncovering areas that should be prioritized for further investigation.

Climate And Lawn Management Interact To Control C4 Plant Distribution In Residential Lawns Across Seven U.S. Cities, Tara Trammell, Diane E. Pataki, Christopher Still, James Ehleringer, Meghan Avolio, Jennifer L. Morse, Multiple Additional Authors

Environmental Science and Management Faculty Publications and Presentations

In natural grasslands, C4 plant dominance increases with growing season temperatures and reflects distinct differences in plant growth rates and water use efficiencies of C3 vs. C4 photosynthetic pathways. However, in lawns, management decisions influence interactions between planted turfgrass and weed species, leading to some uncertainty about the degree of human vs. climatic controls on lawn species distributions. We measured herbaceous plant carbon isotope ratios (δ13C, index of C3/C4 relative abundance) and C4 cover in residential lawns across seven U.S. cities to determine how climate, lawn plant management, or interactions between climate and plant management influenced C4 lawn cover. We …

Development Of The Aaspire Web Accessibility Guidelines For Autistic Web Users, Dora Raymaker, Steven K. Kapp, Katherine E. Mcdonald, Michael Weiner, Elesia Ashkenazy, Christina Nicolaidis

OHSU-PSU School of Public Health Faculty Publications and Presentations

Websites figure predominantly in everyday life. However, many websites remain inaccessible to autistic people, and existing efforts to improve accessibility are in early stages, do not directly include autistic users in their development, or have not been empirically evaluated. The Academic Autism Spectrum Partnership in Research and Education (AASPIRE) used a community-based participatory research approach to create a website to improve health care access for autistic adults. We used the creation of that website as a “living laboratory” to develop the AASPIRE Web Accessibility Guidelines for Autistic Web Users. Our guidelines are grounded in accessibility theory, had autistic end-user involvement …
