Factor Structure Of The Short Form Of The Barratt Impulsiveness Scale (Bis-15) In An Early Adolescent, Non-Clinical Population, Phuc Toan Nguyen

University Honors Theses

The Barratt Impulsiveness Scale (BIS) is a widely used tool for measuring impulsivity and has been influential in shaping current theories of impulse control. Studies have found that BIS factor structures can vary between different populations. The present study examined the factor structure of the widely used shortened form of BIS (BIS-15) within an early adolescent population. The BIS-15 has fifteen questions thought to assess three factors of impulsivity: non-planning, motor, and attentional impulsivity. This study applied confirmatory factor analysis to a cross-sectional sample of 612 middle school students in grades six through eight. The published factor structure of the …

Mathematical Silences, Matthew Nathan Petersen

Dissertations and Theses

Previous studies have shown that mathematicians employ lengthy silences in their collaborations, contrary to the norms that govern every-day collaborations. Such results shows the relevance of an investigation of silence in mathematical collaboration. This dissertation builds off these results in a series of three papers. The first paper describes a methodology that can be employed in the investigation of silence in mathematical collaboration. The second paper analyses silence in the mathematical collaboration of students in junior-level introductory proof classes. It identifies two forms of mathematical activity, reading and ruminating, that students regularly engage in, and which violate the norms of …

A Multi-Scale Assessment Of The Relationship Between The Riparian Landscape And The Health Of Streams In Portland, Oregon, Dylan Esmonde

Environmental Science and Management Professional Master's Project Reports

The riparian areas adjacent to streams are sensitive and important environments that have a great deal of influence on the overall health of the streams they border. In cities, riparian areas are routinely impacted and degraded by property developments, urban infrastructure, and other alterations to the natural environment. In this study, I worked with the City of Portland to determine how a wide range of landscape features occurring in riparian areas affect the overall health of streams at multiple scales. Data were collected from buffer areas of widths ranging from 15 ft to 500 ft that were digitally generated around …

Long Term Changes To The Lower Columbia River Estuary (Lcre) Hydrodynamics And Salinity Patterns, Aqeel Al-Bahadily

Dissertations and Theses

Changing the morphological and hydrological conditions of an estuary can affect the estuarine hydrodynamics. The hydrograph of the Lower Columbia River Estuary (LCRE) and its bathymetry have been altered significantly over the past 150 years, such that the spring-freshet has decreased by 40-50% while winter flow has increased by 50%. In addition, the inlet width has been narrowed from 9.7 to 3.2km by the construction of jetties, and the controlling depth of the navigation channel has been deepened from 6 to 13m by continuous dredging. Also, ~70% of the shallow water habitat has been lost due to diking and wetland …

The Role Of Strategic Governance In Reducing Infant Mortality Under Crisis Conditions, Lynn Christine Finley

Dissertations and Theses

The infant mortality rate (IMR) in some developing countries has decreased faster than the global average even though these countries lack strong economic growth, good governance, and democracy (often acknowledged precursors to improved health outcomes). What accounts for the improvement of the IMR in the absence of these traditional pathways to health gains? Some scholars suggest that the concept of "strategic governance" might help direct attention to intermediary factors that reduce neonatal deaths in countries that experience crisis conditions. The main objective of this dissertation is to investigate the set of governance practices that have reduced IMR in two such …

Settler Colonial Curriculum In Carlisle Boarding School: A Historical And Personal Qualitative Research Study, Patrick Gerard Eagle Staff

Dissertations and Theses

This dissertation research study brings together a historical account and one scholar's personal and family stories of how Indigenous children were stolen and sent to the first Bureau of Indian Affairs (BIA) boarding schools and tribal schools. In the case of the researcher's family, the educational experiences at Carlisle Indian Industrial School immediately started a traumatic assimilation process on Indigenous children that instilled generational trauma for them and their descendants. At these schools, Indigenous children were forced to conform to a foreign European school designed to abolish their Indigenous identity that demanded they give up their language and culture to …

The Economically Disadvantaged Speak: Exploring The Intersection Of Poverty, Race, Child Neglect And Racial Disproportionality In The Child Welfare System, Angela Gail Cause

Dissertations and Theses

The relationship between poverty and child maltreatment has long been addressed in the literature. Disproportionally, children, especially those of color, are more likely to live in poverty than adults. It has been established that the risk of child maltreatment increases the longer impoverishment is experienced. Thus, the likelihood that racial disproportionality may have negative impact upon the child welfare system is potentially increased. Much attention has been given to the overrepresentation of certain children of color within the child welfare system when cared to their representation within the general population. This study explores the intersection of poverty and race upon …

Addressing Structural Inequalities In Planning Processes: A Case Study Of An Equity Lens, Marta Conklé Mcguire

Dissertations and Theses

The use of equity lenses is growing rapidly in the public sector as a means to reform institutional practices that produce racialized outcomes; yet, organizations are interpreting and using an equity lens in different ways, leaving open questions on the extent to which a lens addresses structural inequalities. This dissertation focuses on an in-depth case study of a planning process that incorporated an equity lens in the development of a large scale urban system plan in Portland (OR) to build understanding of how an equity lens may change the institutional planning process. Insights from the study suggest an equity lens …

Factors Affecting Clinical Research Enrollment Among Individuals With Alzheimer's Disease And Related Dementias, Nicole Grace Bouranis

Dissertations and Theses

The need to increase ADRD research participation has become more pressing as the prevalence of ADRD increases. Nearly 70,000 Oregonians and 7 million people in the United States live with ADRD, and this number is expected to increase by 200% by 2050 without identification of an intervention to halt its increase. Developing mechanisms for effective care and treatment depends on implementing research with numerous participants. Historically, ADRD research programs have had difficulty recruiting and enrolling individuals into studies for a variety of reasons. Given low recruitment rates, the interest in researching and evaluating effective strategies to recruit specifically for ADRD …

Animal Magic, Secret Spells, And Green Power: More-Than-Human Assemblages Of Children's Storytelling, Angela Molloy Murphy

Dissertations and Theses

Early childhood settings have become contested spaces, or sites of struggle, between economic and sociocultural interests disputing their purpose. Recent years have shown increased pressure on children in early education settings to demonstrate predetermined learning outcomes, which (a) limits the scope of what is possible in the classroom, (b) narrows the range of what learning is considered valid, and (c) privileges the experience and values of the dominant culture, thereby determining who and what matters in early childhood settings. Thus, in the current education climate where conventional knowledges are routinely privileged, unconventional knowledges and small stories from children's lives are …

Convex And Nonconvex Optimization Techniques For Multifacility Location And Clustering, Tuyen Dang Thanh Tran

Dissertations and Theses

This thesis contains contributions in two main areas: calculus rules for generalized differentiation and optimization methods for solving nonsmooth nonconvex problems with applications to multifacility location and clustering. A variational geometric approach is used for developing calculus rules for subgradients and Fenchel conjugates of convex functions that are not necessarily differentiable in locally convex topological and Banach spaces. These calculus rules are useful for further applications to nonsmooth optimization from both theoretical and numerical aspects. Next, we consider optimization methods for solving nonsmooth optimization problems in which the objective functions are not necessarily convex. We particularly focus on the class …

Exploring The Role Of Transformational Leaders In The Mentorship Of Top-Level Administrators: A Case Study Of The Veterans Health Administration (Vha) Visn Lead Program, Frederick Giovanni White Jr.

Dissertations and Theses

Despite the proliferation of studies focused on transformational leadership, there is a lack of clarity related to how transformational leaders are developed in public organizations and the impact of mentors in this process. This is particularly troubling given a 2017 Bureau of Labor Statistics estimate that over 44% of the current U.S. workforce is 45 years or older.

In public and private settings, organizations are challenged to develop the competencies critical at higher levels of management in their future leaders, specifically advanced human and conceptual skills. These skills are most useful for emerging leaders that will have the responsibilities to …

From Theory To Practice: Interdisciplinary Science In Undergraduate Education, Brie Tripp

Dissertations and Theses

Science has undergone a major transformation in the 20th and 21st centuries with new fields emerging at the intersection of disciplines, such as bioethics, bioinformatics, and chemical ecology. Yet, opportunities to engage with interdisciplinary science, and the skills needed to work in these fields, are largely absent from undergraduate biology classrooms. As a consequence, students are potentially deprived of opportunities to think interdisciplinarily and engage with real-world issues that often necessitate interdisciplinary efforts. To be informed citizens in society and forward-thinking scientists in the workforce, undergraduate students will undoubtedly benefit from exposure to these interdisciplinary science experiences.

Given these considerations, …

Spatial Politics And Literacy: An Analysis Of Little Free Libraries And Neighborhood Distribution Of Book-Sharing Depositories In Portland, Oregon And Detroit, Michigan, Desiree Wilson

Book Publishing Final Research Papers

The purpose of this research is to interrogate whether Free Little Libraries (LFL), the largest branded book-sharing movement in the world, continues to uphold its currently stated mission to provide book access to communities where book accessibility is low (determined by how many estimated books are in each household). Though the Little Free Library nonprofit has flourished in the decade since it was founded, indicating a fondness and appreciation for the Little Library as an idea and neighborhood ornament alike, critics of the organization have raised multiple concerns about whether the library boxes provide service to those who need them. …

The Library Has Infinite Streaming Content, But Are Users Infinitely Content? The Library Catalog Vs. Vendor Platform Discovery, Jian Wang, Elsa Loftis

Library Faculty and Staff Publications and Presentations

Despite the widespread adoption of streaming video by academic libraries, there has been little discussion about how video content is discovered and accessed through the library catalog as compared to vendor platforms. This article explores the current status of video resources in the library catalog to better understand how users find and access streaming content. MARC records were evaluated, and searches were performed to gauge issues related to metadata quality and its impact on discovery. The study reveals new trends in how users access streaming content for teaching, learning, and research.

Critical Library Instruction As A Pedagogical Tool, Nicole A. Cooke

Communications in Information Literacy

The opportunity to expand pedagogy is an especially good thing for library educators, particularly when library professionals do not have formal training as teachers and instructors. We have a responsibility to ourselves and our students to grow intellectually and share growth and new knowledge with others. We should be promoting and practicing critical self-reflection and thinking critically about and even critiquing the information we consume and the sources from which it originates. This is an ongoing and iterative process that requires that we consistently read and remain abreast of new and interdisciplinary ideas that can challenge and inform our practice. …

Teacher As Stranger: Unfinished Pathways With Critical Pedagogy, Caroline Sinkinson

Communications in Information Literacy

In 2010, Accardi, Drabinski, and Kumbier published the edited collection Critical Library Instruction, which marked a turn to more broadly integrate critical theory into the practice and literature of librarianship. This article looks back ten years to trace how critical pedagogy continues to provoke librarians' reflective measurement of the coherence between theory and practice, whether in the classroom or in advocacy for open education. With Paulo Freire’s notion of unfinishedness and Maxine Greene’s metaphor of ’teacher as stranger,' the article explores the nature of teaching as a continuously reflective and creative act.

That Was Then, This Is Wow: A Case For Critical Information Literacy Across The Curriculum, Margaret Rose Torrell

Communications in Information Literacy

This article applies a Writing across the Curriculum approach to Critical Library Instruction. The information landscape has drastically shifted over the past ten years, altering the ways we perform, interact with, access, and understand research. These changes call for critical library instruction programs that are more robust and sustained than the one- or two-shot critical library instruction lesson I had described in 2010. However, college classroom practices, due to a variety of challenges, have been slow to adapt to this need. In this article written from my perspective as an English teacher, I identify the central place of critical information …

Building A Critical Culture: How Critical Librarianship Falls Short In The Workplace, Jennifer A. Ferretti

Communications in Information Literacy

Critical librarianship, or critlib, has made its way into the mainstream of library and information science through conferences, scholarly publications, social media, and other outlets. Over the past 10 years critical library instruction specifically has continued to be a much presented and published topic. Classes and other groups that come through our libraries are opportunities for us to teach, learn, and empower. The care and critical perspectives we bring into the classroom are necessary, but are we also fostering this type of environment in the workplace? Are we doing enough to turn the critical lens on ourselves? As a woman …

Addressing transportation-related barriers is an essential part of Clackamas Community College's mission to make education more accessible. This plan provides a student-centered analysis of barriers that make it difficult for students with limited access to personal vehicles to access CCC’s Oregon City and Harmony campuses and identifies strategies to overcome them. The plan focuses on the CCC Xpress Shuttle, which sees over 26,500 trips per academic year, and on the compounded barriers facing students of color, low-income students, and students with disabilities.

Sea Surface Microplastics: An Inshore-Offshore Gradient Off The Olympic Peninsula, Rosemary Wood

University Honors Theses

The lack of baseline data regarding plastic debris moving through and accumulating in various environmental compartments creates a vast gap in the literature for a number of reasons. These include a current lack of codified methodology to characterize microplastics both in morphology and polymer type, as well as gaps regarding contamination control & validation techniques. In September of 2019, sea surface sampling took place off the Olympic Peninsula, WA with the goal of addressing the following three research questions. First, is variability in microplastic abundance driven by transect location, distance from shore, or both? Second, how does microplastic type, in …

Individual And Community Supports That Impact Community Inclusion And Recovery For Individuals With Serious Mental Illnesses, Rachel Elizabeth Terry

Dissertations and Theses

The current dissertation presents two published manuscripts and discusses a third study that explored the role of social support in promoting community participation for individuals with serious mental illnesses. The first manuscript investigated sense of community as a potential mediating factor between community participation, psychological distress, and mental health functioning utilizing quantitative methods. The results indicated that sense of community acted as a partial mediator between community participation and psychological distress, as well as mental health functioning. The second manuscript is a literature review that explored the influence of social support on community integration for individuals with serious mental illnesses. …

Collaboration And Evaluation In Urban Sustainability And Resilience Transformations: The Keys To A Just Transition?, Liliana Elizabeth Caughman

Dissertations and Theses

Climate has changed and will continue changing; city populations are swelling as urbanization continues to accelerate; extreme environmental events like heat waves and floods are becoming more severe and more common; and the climate justice movement is rapidly gaining momentum. It in this context that municipal governments find themselves urgently seeking solutions to transition cities from extractive, vulnerable, and unjust to sustainable, resilient, and equitable. The task is complex and will require systemic transformations across interconnected social, environmental, and economic infrastructures. Emerging theories regarding how to govern such massive changes suggest Transition Management strategies and the values of a just …

Where's The Learning In On-Campus Student Employment? An Inquiry Into The Experiences Of Undergraduate Student Employees, Patricia Ann Dorman

Dissertations and Theses

Student employees spend a significant amount of time at work. Prior research has primarily focused on the deleterious academic impacts on students, with little consideration of how student employment could be effectively framed as an educationally purposeful activity. This qualitative study explored how individual, social, and organizational factors influence learning while working on campus. In-depth, semi-structured interviews were conducted with undergraduate student employees who work within student affairs units. The findings indicate that on-campus employment is a site for learning; particularly competency development in communication, professionalism, problem solving, and leadership skills. Interdependent personal, interpersonal, and environmental factors of campus employment …

#Adultingwhileblack: Encountering In The Campus Climate And The Formation Of Racialized Adult Identity Among Traditional-Age Black College Students, Sarah Nana Kutten

Dissertations and Theses

The college years represent a time when traditional-age students transition from adolescence to adulthood. During this period, many Black students encounter racist campus climates that can hinder their academic success and lead to marginalization and departure. Educational scholars have long understood the relationship between identity development and college student success, yet adult identity models often fall short for Black students because they do not consider the impacts of racism on development. As such, Black students face systemic, organizational, and individual racist encounters in higher education that keep them from fully engaging in the college experience and their personal development. This …

"I Should Have Moved Somewhere Else": The Impacts Of Gentrification On Transportation And Social Support For Black Working-Poor Families In Portland, Oregon, Steven Anthony Howland

Dissertations and Theses

Portland has faced a mass displacement of Black households from the historically segregated area of Albina through various phases of urban renewal, urban deterioration, and gentrification. A substantial number of them have moved to East Portland, a suburban segment of the City of Portland that was unincorporated county land prior to the 1990's. As Black people have left Albina, the roots of Blackness there have eroded from the area as businesses and churches catering to them have also closed as a result of lost patrons.

In this study I interviewed 27 low-income working-age Black people with children with the sample …

Identifying A Starting Point For The Guided Reinvention Of The Classification Of Chemically Important Symmetry Groups, Anna Marie Bergman

Dissertations and Theses

The study of abstract algebra is both required for most mathematics majors and notoriously difficult. Much of the mathematics education literature on investigating student thinking in abstract algebra highlights student struggles with understanding even the most fundamental concepts. The abstract nature of the content of the course has been credited as one of the contributors to student difficulties. While there have been various instructional innovations designed to support students in better understanding abstract algebra, and group theory in particular, they have not specifically focused on the issue of the abstract nature of the content. My dissertation study aimed to develop …
