The Influence Of Shared Mobility And Transportation Policies On Vehicle Ownership: Analysis Of Multifamily Residents In Portland, Oregon, Edgar Bertini Ruas

Dissertations and Theses

Since the beginning of the 21st Century, the world has seen the rapid development of the so-called "sharing economy" or collaborative consumption (Botsman, 2010). One of the first areas affected by the shared economy is vehicle ownership. With the emergence of several new providers of mobility services, such as Uber and car2go, there has been the promise of changes to the traditional way of owning and using a vehicle (Wong, Hensher, & Mulley, 2017). One potential consequence of shared mobility services is the reduction in vehicle ownership. At the same time, cities are trying to anticipate these changes by reducing …

Physical And Emotional Sibling Violence And Child Welfare: A Critical Realist Exploratory Study, Katherine Elizabeth Winters

Dissertations and Theses

Sibling violence is a pervasive, yet poorly understood and substantially underreported phenomenon. Currently recognized as the most common form of intra-familial abuse, various estimates suggest that 30 percent or more of children in the general population experience severe acts of violence inflicted by a sibling each year.

Given that many young people in the child welfare system experience the family conditions associated with abusive sibling violence, recent publications have implored child welfare to embrace the notion that it is a form of child maltreatment. Practitioners and policymakers have yet to reach agreement on what constitutes physical or emotional abuse between …

Racial Disparities In A State Based Workers' Compensation System, Caroline Kristine Smith

Dissertations and Theses

Racial, ethnic, and linguistic minority workers suffer higher rates of work-related injuries and illnesses in the United States compared to their White counterparts. Explanations for these higher rates include potential socioeconomic causes (education, income, and wealth) and occupational segregation into more dangerous occupations. What is less studied are the post-injury sequelae for minority workers, which is their experiences in the workers' compensation system, as well as their health and return to paid employment. What is known comes primarily from qualitative literature, which includes themes of racial discrimination (from employers, health care providers, and workers' compensation employees), a lack of information …

The Infrastructural Function: A Relational Theory Of Infrastructure For Writing Studies, Sarah Read

English Faculty Publications and Presentations

This article theorizes the term infrastructure as a framework for articulating how writing products, activities, and processes underwrite organizational life in technical organizations. While this term has appeared broadly in writing studies scholarship, it has not been systematically theorized there as it has been in other fields such as economics, computing, and information science. This article argues for a four-part framework that incorporates and builds on Star and Ruhleder’s relational theory of infrastructure. Fieldwork from a federally funded supercomputing center for scientific research operationalizes the theory for its contributions to writing studies scholarship and its applications for industry and writing …

Opening Up Open Access Institutional Repositories To Demonstrate Value: Two Universities’ Pilots On Including Metadata-Only Records, Karen Bjork, Rebel Cummings-Sauls, Ryan Otto

Library Faculty and Staff Publications and Presentations

Introduction: Institutional repository managers are continuously looking for new ways to demonstrate the value of their repositories. One way to do this is to create a more inclusive repository that provides reliable information about the research output produced by faculty affiliated with the institution.

Description of Program: This article details two pilot projects that evaluated how their repositories could track faculty research output through the inclusion of metadata-only (no full-text) records. The purpose of each pilot project was to determine the feasibility and provide an assessment of the long-term impact on the repository’s mission statement, staffing, and collection development policies. …

From Refugee To Citizen: Rhizomes And Roots In The Digital Age, Julia Nett

University Honors Theses

This thesis examines digital media as platforms for current and former refugees to reaffirm and create themselves and to learn to be American. To think of refugees as "uprooted" with "roots that threaten to wither" (Malkki 1992, 32) is misguided. This thesis utilizes Deleuze and Guattari's idea of the rhizome (1987) to rethink current and former refugee experiences post-resettlement in the US. With the rising ubiquity of digital media and digital technologies, increasing numbers of refugees resettle with smartphones and other technologies. These technologies provide current and former refugees opportunities to maintain hybridized self-conceptions and to feel they are both …

Challenges In Designing A Mentorship Program For Electrical Engineering Freshmen, Branimir Pejcinovic, Melinda Holtzman

Electrical and Computer Engineering Faculty Publications and Presentations

This Work in Progress Innovative Practice Paper addresses three challenges we face when teaching freshmen: a) how to present a wide variety of sub-fields in electrical engineering, b) how to establish the relevance of electrical engineering to things they care about, and c) how to relate electrical engineering to students' experiences. We are attempting to address these through a mentorship program involving recent alumni working with teams of freshman electrical engineering students. Mentors are expected to: (i) come to class and speak about their job experience, (ii) meet with their teams early in the term to help them get started …

The Nonprofit Nerd (March 2019), The Nonprofit Institute At Portland State University

The Nonprofit Institute Newsletter

This month’s topic is evaluation with trauma survivors.

This issue, we are examining the unique considerations of evaluating programs working with trauma survivors. With the help of Vanessa Timmons, Executive Director of the Oregon Coalition Against Domestic and Sexual Violence (OCADSV), we will explore methods for evaluating programs, including “survivor-led evaluation.”

More funders are asking nonprofits to relate services to ACEs and evaluate trauma-informed practice. Many organizations have always seen this connection between trauma and the nonprofit sector, even when services are not specific to healing from trauma.

Who do you visualize when you hear “trauma survivor?” Perhaps you …

A New Product Anti-Counterfeiting Blockchain Using A Truly Decentralized Dynamic Consensus Protocol, Naif Alzahrani, Nirupama Bulusu

Computer Science Faculty Publications and Presentations

The growth of counterfeit goods has plagued the international community for decades. Nowadays, the battle against counterfeiting remains a significant challenge. Most of the current anti‐counterfeiting systems are centralized. Motivated by the evolution of blockchain technology, we propose (Block‐Supply), a decentralized anti‐counterfeiting supply chain that exploits NFC and blockchain technologies. This paper also proposes a new truly decentralized consensus protocol that, unlike most of the existing protocols, does not require PoW and randomly employs a different set of different size of validators each time a new block is proposed. Our protocol utilizes a game theoretical model to analyze the risk …

Perceptions Of Emotions By Simultaneous Bilinguals Across Various Relationship Contexts, Lisa A. Wickham

University Honors Theses

Currently, a significant amount of existing research on bilinguals does not distinguish between sequential and simultaneous bilingualism. Furthermore, there is a significant gap in the existing research on simultaneous bilinguals. This exploratory study investigated simultaneous bilinguals’ perceptions of emotional expression in their two first languages, within three relationship contexts: professional, family, romantic partners and friends. A questionnaire was administered to simultaneous bilinguals. According to the findings of this study, simultaneous bilinguals have a preference between one of their first two languages when expressing certain emotions. Additionally, participants report that relationship context impacts the language they select to use when conversing …

Japantown Pdx, Euri Kashiwagi

University Honors Theses

Japantown was a community of Japanese immigrants existing in Portland in where Old Town Chinatown is currently located from 1890 to 1941. Due to law changes and the occurrence of World War II, the community came to an end as the people there had to move to internment camps or back to Japan. This project will be a revival proposal of Japantown into present time Portland incorporating the current needs of the city. The book will include a logo for the community and district, as well as multiple deliverables that will be used to advertise and run the community through …

Efficient And Scalable Event Tracing, Rupika Dikkala

University Honors Theses

In this work, I demonstrate that a time series database can be utilized to store Open Trace Format 2 (OTF2) file metadata for common trace events efficiently and scalably. This paper examines the efficacy of storing event trace data in a time series database, and investigates associated performance overhead compared to the state of the art method using OTF2 trace files. The sample traces used in this project are generated from a parallel hydrodynamic modeling code, Lulesh, developed at Lawrence Livermore National Laboratory. In my approach, I first cache common event trace metadata in InfluxDB, a contemporary time series database. …

Farmer Attitudes Toward Cooperative Approaches To Herbicide Resistance Management: A Common Pool Ecosystem Service Challenge, David E. Ervin, Elise H. Breshears, George B. Frisvold, Terrance M. Hurley, Katherine E. Dentzman, Jeffrey L. Gunsolus, Raymond A. Jussaume, Micheal D. K. Owen, Jason Norsworthy, Mustofa Mahmud Al Mamun, Wesley Everman

Environmental Science and Management Faculty Publications and Presentations

Dramatic growth in herbicide-resistant (HR) weeds in the United States threatens farm profitability and may undercut environmentally beneficial farming practices. When HR weeds move across farm boundaries due to ecological processes or human action, a common pool resource challenge emerges, requiring farmer cooperation to manage such weeds effectively. We investigate the scope for cooperative management using responses to a national survey on HR weed issues to test a recursive model of three preconditions for collective action: (1) concern about HR weeds migrating from nearby lands; (2) communication with neighbors about HR weeds; and (3) belief that cooperation is necessary for …

"It Lurks In The Saying, Not What's Being Said": Possible Worlds Theory And Gender Performativity In Marina Carr's Low In The Dark, Andie Madsen

University Honors Theses

Low in the Dark by Irish playwright Marina Carr is an absurdist play that focuses heavily on concepts of gender as performance. It does so mainly through role-playing scenes in which two same-gender characters reenact a heterosexual relationship. These scenes can be tied to Marie-Laure Ryan’s conceptions of the four kinds of alternative possible worlds (APWs) within possible worlds theory: fantasy, wish, obligation, and knowledge. An analysis of the play’s role-playing scenes in conjunction with Judith Butler’s gender performativity theory and these four types of APW reveals the constructed-ness of gender norms within the work, which further calls into question …

"Infinite Time And Just A Little Bit Of Mystery": Time, Theme, And Playability In 17776 And The Stanley Parable, Rachel Dutton

University Honors Theses

From a number of theoretical frameworks, such as media-specific analysis, playability, and the infinite canvas, I work to analyze the function of time as a mechanic in both 17776 by Jon Bois and The Stanley Parable published by Galactic Cafe. Through this analysis, my research highlights the ways in which both of these works use time as an element of their playability in order to foster emotional reaction from the player. This reaction creates an experience and awareness of the work’s thematic arguments and makes them apparent to the player. Because of this extensive use of time in two significant …

Incivility As A Veiled Display Of Workplace Discrimination: The Intersection Of Workplace Incivility And Gender-Based Discrimination, Sara M. Grant

University Honors Theses

Workplace incivility is defined as behavior that is rude, condescending, and/or ostracizing. Incivility violates workplace norms or expectations of respect but can otherwise appear mundane. Incivility is low impact but consistent mistreatment that can result in a myriad of negative impacts on employees and organizations. Some organizations dismiss incivility and other forms of subtle mistreatment as inconsequential, despite scientific evidence showing significant costs. A combination of anti-discrimination laws and social norms have drastically changed the dynamics of workplace discrimination over the last few decades. That is, blatant discrimination is no longer socially or legally acceptable, but biased attitudes against women …

V2x: Bringing Bikes Into The Mix, Stephen Fickas

TREC Final Reports

This project demonstrates how an inexpensive system (hardware and software) can add new functionality to existing signal controllers, giving bicyclists an efficient way to cross a controlled intersection. The system integrates three components: (1) a Bike Connect box that resides near the signal-controller and is connected to it, (2) an application that runs on a Bike Connect device (currently an iPhone) and requests a green light at the correct approach-distance, and (3) a cloud-based publish/subscribe (pub/sub) component that handles cellular-communication between phone app and box. One stumbling block for the project was a means to obtain reliable GPS data to …

Unintended Consequences: How Suppliers Compensate For Price Concessions And The Role Of Organizational Justice In Buyer-Supplier Relations, Steven Carnovale, John W. Henke, Scott Duhadway, Sengun Yeniyurt

Business Faculty Publications and Presentations

“You get what you pay for” is one of life's lessons that predominates in purchasing decisions individuals make in their personal lives. The results of this study suggest this lesson should also prevail among management when price‐related purchasing decisions in businesses are being made. An evaluation of over 1,700 purchasing instances across seven years of a longitudinal panel data set collected from Tier 1 production suppliers to the six major North American automotive Original Equipment Manufacturers (OEMs), Chrysler, Ford, General Motors, Honda, Nissan, and Toyota, found that suppliers compensate for price concessions and price reduction pressure from the OEM in …

An Expert Discussion On Autism And Empathy, Damian Milton, Noah J. Sasson, Elizabeth Sheppard, Melanie Yergeau, Christina Nicolaidis

School of Social Work Faculty Publications and Presentations

As early as 1962, psychologists described children with “autistic psychopathy” as being “unable to achieve empathy.”² An empathy deficit has since become a core feature in many conceptualizations of autism, including the Theory of Mind (or mind-blindness) model and the Empathizing-Systematizing model.³ Researchers have distinguished between cognitive empathy (or theory of mind; the capacity to understand another person’s perspective or mental state) and emotional or affective empathy (the capacity to experience affective reactions to the observed experiences of others), asserting that autistic individuals have deficits in the former, but not in the latter.⁴,⁵ Even this …

Language And Culture As Barriers To Healthcare For Chinese Immigrants, Edwin Leung

University Honors Theses

Immigrants and their descendants are projected to account for 88 percent of United States population growth through 2065. Currently, immigrants make up for about 13.5 percent of the US population. In addition, 65.5 million Americans speak a language other than English at home. Language and culture are the two most significant barriers faced by immigrants seeking health care. These barriers have a significant impact on immigrants’ ability to receive quality care, make them more vulnerable to poor health outcomes. Many resources exist to help immigrants with various needs including health care. However, more effort is needed to strengthen the resources …

Webinar: Rethinking Streets For Bikes: An Evidence Based Guide Of Bike-Friendly Street Retrofits, Marc Schlossberg, Roger Lindgren

TREC Webinar Series

There is a growing demand for better infrastructure and fewer barriers to biking and other forms of space-efficient micromobility. Tackling daily trips by bike is easier on the environment, healthier for users and non-users alike, uses precious urbanized public and private land more efficiently, costs taxpayers less to build and maintain infrastructure, and when routes are safe and comfortable, moving by bike is also fun! Complete Streets policies are being adopted across the country, and there is an active conversation around the safety imperative of a Complete Streets approach. Yet, local officials often need both design guidance and the …

Webinar: Words Matter: Recognizing And Addressing Modal Assumptions To Shift Transportation Culture, Barb Chamberlain

TREC Webinar Series

Search #DriverNotCar or #CrashNotAccident on Twitter and you’ll find a vigorous discussion about the power of word choices to shape our understanding of what happens on the street and who’s responsible. When we directly examine and discuss the language we use, we acknowledge its power both to reflect existing attitudes and to shape developing attitudes. This presentation will uncover embedded biases or assumptions in common transportation terminology and provide tips and tools to help us broaden our inclusion of everyone we are supposed to serve as transportation professionals.

Iot And Digitization Will Reconnect System Engineering And Science, John Blyler

Systems Science Friday Noon Seminar Series

The fully connected world is quickly becoming a reality. Architects and developers of this new world must understand both the hardware and software basics of IoT and IIoT systems as well as the proven way to deal with the complexities of the integration of sensors, processors, wireless connectivity, edge to cloud networks, data partitioning and processing, AI, machine language, digital threads and twins, and much more. Such complexity can only be handled with a systems-of-systems (SoS) engineering approach.

But while systems engineering may hold many of the solutions to IoT challenges, systems engineering must evolve from its traditional role. Some …

Diachronics Of Redemption: A Systems Theoretic View Of Rosenzweig’S Star, Martin Zwick

Complex Systems Faculty Publications and Presentations

This paper explores Rosenzweig’s idea of Redemption by an interpretative examination of the conceptual structures of the Star. These structures, in which Redemption is integrated with the other two relations, Creation and Revelation, and with the three elements of God, World, and Human, are examined from the perspective of contemporary systems theory. Moses, Pollock, and others have noted the systematic character of the Star. While “systematic” does not necessarily mean “systems-theoretic,” the philosophical theology of the Star and its core hexad of elements and relations exemplify many ideas salient in the systems theory literature. The hexadic star itself fits the …
