A Look At The Missing And Murdered Indigenous Women Crisis: Investigation Of Potential Causes And Effects, Verity Saige Vogel

University Honors Theses

In North America, Indigenous women go missing and are murdered at a rate higher than any other demographic. Scholars and governmental agencies agree that the Missing and Murdered Indigenous Women (MMIW) crisis is a pressing issue; it was not until a series of successful social media campaigns (using the hashtag #MMIW) and other grassroots activism took root across First Nations and Native communities in North America that the gravity of the situation became widely reported. Although many agree that the MMIW crisis is a wicked problem (in that it has many contributing factors that amplify its effect and contribute to …

Batterer Intervention Program Evaluation: A Portland, Oregon Program Case Study, Julie M. Conner

University Honors Theses

Batterer intervention programming (BIP) has shown up as a source of treatment for men who abuse women since the late nineteen-seventies and have since continued to expand. Research has been done to examine how effective these programs are in many different settings at reducing intimate partner violence, but little is known about programs specific to the state of Oregon. BIPs are used as an alternative to incarceration for individuals convicted of domestic violence: existing programs are based on the Duluth Model and Cognitive Behavioral Theory (CBT). Other modalities have utilized trauma-informed approaches, psychoeducation, holistic modeling, and risks, need, and responsivity …

Gender Differences In Parental Leave Before And After The Introduction Of A Paid Parental Leave Policy: A Sequence Analysis Of Administrative Time-Keeping Records, Julia M. Goodman, Lisset Dumet Poma, David Hurtado, Anna Steeves-Reece, Dawn M. Richardson

OHSU-PSU School of Public Health Faculty Publications and Presentations

Paid leave confers health benefits to new parents and their children, but the absence of a national paid family leave policy in the United States has left workers to navigate a patchwork of paid and unpaid parental leave benefits accessed through their employers. As public and private paid leave policies expand across the US, it is imperative to determine how these benefits impact leave taking behaviors among new parents. We use sequence and cluster analyses of administrative time-keeping records to detail parental leave-taking during the first 180 days after adding a child among employees of a large public-sector organization with …

The Right To The University: The Experiences Of Mexican/Mexican American/Xicanx Students At A Predominantly White University In Upstate New York, Martín Alberto Gonzalez

Chicano/Latino Studies Faculty Publications and Presentations

Having the right to a space is not only the right to be present without being harassed or bothered, but it also includes the right to have a say in how that space should be experienced. Yet, spaces have long been contested and not everyone has equal access to shared spaces. This paper examines the experiences of Mexican/Mexican American/Xicanx (MMAX) undergraduate students at a predominantly white university in the Northeast. Drawing on indepth interviews, participant observations, pláticas, and document analyses, I argue that MMAX students do not have the right to their respective university because their university does not address …

Science Education Research On Student To Student Discourse: A Literature Review With An Applied Linguistics Lens, Abbee A. Mortensen

University Honors Theses

Science education researchers have increasingly been using discourse analysis to research small group discussion while doing course related activities. This literature review examined studies from that discourse community to see what analysis methods were used and if they connected to applied linguistics theories or methods. Two of the most common discourse analysis frameworks used were Toulmin's Argument Pattern and grounded coding schemes that looked at the design and specific contents of the discourse. Studies covered will also include education scholars using theories of conversation analysis and normative pragmatics to make a more explicit connection to applied linguistics. Orienting and drawing …

Together Or Apart? The Effects A Parent's Relationship Dynamic Has On Their Child(Ren)'S Romantic Relationship, Kailee Delos Santos

University Honors Theses

The relationship between parents is considered one of the most influential interactions a child will experience; as it is usually the first relationship a child witnesses where personal values and interests develop (Stanger, 2019). Nonetheless, it is a consistently understudied population in family research and, when studied, children are primarily examined during adolescence and often only in the context of conflict and rivalry. Additionally, much of this research does not examine the effects of a child's romantic relationship on the larger family system. This thesis seeks to address this gap in the literature by understanding how the relationship of a …

Automatically Generating Scenarios From A Text Corpus: A Case Study On Electric Vehicles, Christopher W.H. Davis, Antoine J. Jetter, Philippe J. Giabbanelli

Engineering and Technology Management Faculty Publications and Presentations

Creating ‘what-if’ scenarios to estimate possible futures is a key component of decision-making processes. However, this activity is labor intensive as it is primarily done manually by subject-matter experts who start by identifying relevant themes and their interconnections to build models, and then craft diverse and meaningful stories as scenarios to run on these models. Previous works have shown that text mining could automate the model-building aspect, for example, by using topic modeling to extract themes from a large corpus and employing variations of association rule mining to connect them in quantitative ways. In this paper, we propose to further …

Planning And Real-Time Resource Allocation In Freight Logistics Systems Utilizing Emerging Transportation Technologies, Darshan Rajesh Chauhan

Dissertations and Theses

Transportation is a key driver of any national economy. In the United States, the transportation sector contributes $1.3 trillion to the economy, of which freight transportation represents more than 50%. Trucks alone account for more than 70% freight movements in the United States. In addition to worsening stress at ports of entry and traffic congestion in the system, freight also accounts for nearly one-third of the greenhouse gas emissions in the United States. Emerging transportation technologies like electric unmanned aerial vehicles (or drones) and electric vehicles can provide a more sustainable alternative to combat greenhouse gas emissions and reduce the …

Comparative Foreign Aid Analysis: Replacing The Competition Between Donors With Complementary Aid Policies, Emily Melinda Baker

Dissertations and Theses

Foreign Aid has been a topic of study for decades with few concrete findings on whether it is effective or not. Contemporary foreign aid is divided into two camps: the West and China, with little cooperation and plenty of politics between them. In this thesis I analyze the effectiveness of Western aid and Chinese aid in twelve sub-Saharan African states using annual HDI scores and GDP. I find there is a strong correlation between Western aid and the development measures used as well as cases where Chinese aid is more effective than Western aid. With these findings, I argue that …

Leaving College Without A Degree: The Student Experience At An Urban Broad Access Institution, Andrea Marie Garrity

Dissertations and Theses

This thesis seeks to understand how students who leave college without a degree, or non-completers, experience broad access institutions in an effort to shift our thinking from the student characteristics that predict college dropout to how broad access institutions can better serve students and improve graduation rates. To answer this question, I conducted interviews with former students who had recently attended a broad access institution and left without a degree. Results show that participants expressed internalized views of the traditional college student archetype, which was reinforced through their college experience. Further, participants encountered significant bureaucratic challenges and barriers, and expressed …

If optimally managed and operated, DERs could provide flexibility and highly valuable grid services such as restoration, peak shaving, voltage regulation, and frequency support to maintain grid reliability. Different applications and enterprises, such as distributed energy resources management systems (DERMS), are being developed for coordinated and optimal operation of DERs. However, to attract sufficient DER participation and achieve the coordinated operation of DERs, systems and components must be interoperable and information exchange must be secure. Along this …

Development Of A Configurable Real-Time Event Detection Framework For Power Systems Using Swarm Intelligence Optimization, Umar Farooq

Dissertations and Theses

Modern power systems characterized by complex topologies require accurate situational awareness to maintain an adequate level of reliability. Since they are large and spread over wide geographical areas, occurrence of failures is inevitable in power systems. Various generation and transmission disturbances give rise to a mismatch between generation and demand, which manifest as frequency events. These events can take the form of negligible frequency deviations or more severe emergencies that can precipitate cascading outages, depending on the severity of the disturbance and efficacy of remedial action schema. The impacts of such events have become more critical with recent decline in …

Arbuscular Mycorrhizal Fungi Colonization Response To Dike Removal In The Salmon River Estuary, Elinore Webb

Arbuscular mycorrhizal fungi (AMF) form symbiotic relationships with wetland plants and are important to the restoration of coastal estuaries. The purpose of this study was to assess the presence and colonization of arbuscular mycorrhizal fungi in Distichlis spicata from three formerly diked areas of the Salmon River Estuary to determine an initial understanding of the mycorrhizal community in tidal wetlands post-restoration. AMF were present in all four sample areas and total colonization ranged on average 39-72%. The reference site had the lowest levels of total colonization, which is contrary to the findings of studies of younger wetland restorations. Most importantly, …

Knowledge Overconfidence Is Associated With Anti-Consensus Views On Controversial Scientific Issues, Nicholas Light, Philip M. Fernbach, Nathaniel Rabb, Mugur V. Geana, Steven A. Sloman

Business Faculty Publications and Presentations

Public attitudes that are in opposition to scientific consensus can be disastrous and include rejection of vaccines and opposition to climate change mitigation policies. Five studies examine the interrelationships between opposition to expert consensus on controversial scientific issues, how much people actually know about these issues, and how much they think they know. Across seven critical issues that enjoy substantial scientific consensus, as well as attitudes toward COVID-19 vaccines and mitigation measures like mask wearing and social distancing, results indicate that those with the highest levels of opposition have the lowest levels of objective knowledge but the highest levels of …
