Restorative Practice In Secondary Schools: A Case Study On Leadership, Implementation, And Challenges, Sarah M. Gross

Dissertations and Theses

Students who receive exclusionary discipline (discipline that removes them from the classroom) are less likely to graduate from high school. It has long been documented that students of color, special education students, and boys are more likely to be assigned suspensions and miss classroom instruction. Discipline matrices have been in place across the country and disparities still exist in consequences assigned to individual students. To alter this current reality, school professionals have looked for alternatives. One possibility lies in restorative practices. Restorative practices are strategies that value the whole child and consider not only an act of harm, but also …

Cue Recognition Development Among Undergraduate Nursing Students, Michelle Lynn Lichtenberg

Dissertations and Theses

Clinical judgment among nurses is imperative to assure quality, safe healthcare to all. The licensure exam for registered nurses has been criticized for not adequately measuring the clinical judgment needed by entry-level nurses. The National Board of State Boards of Nursing (NCSBN) responded to this criticism by developing a new Clinical Judgment Measurement Model (CJMM) with measurable cognitive processes, including cue recognition, to be used as a framework for item development on the new licensure exam. Nursing programs must evaluate current teaching and evaluation modalities for alignment with the new CJMM measurable cognitive processes to prepare entry-level nurses for successful …

Is More Always Better? A Look At Visitation And Recidivism, Teriin Lee

Dissertations and Theses

The body of literature on prison visitation provides empirical support that visitation may influence the likelihood of recidivism. However, the literature is limited in both size and geographic representation, as more than half of studies originate from samples in Florida or Minnesota. Moreover, inconsistency in the use of measures further complicates generalizability of the findings. The following study utilizes data collected from the Oregon Criminal Justice Commission to examine the relationship between visitation and recidivism in Oregon. Using a sample of 29,312 adults in custody (AICs) who were released between 2011 and 2017, we test the associations of seven distinct …

Post-Fire Tree Mortality And Regeneration Patterns As Proxies Of Conifer Forest Resilience, Sebastian Upton Busby

Dissertations and Theses

Shifting wildfire patterns and climate conditions, magnified by anthropogenic climate change, are threatening the resilience of conifer forests in North America and more specifically, the western US. If native conifer species are functionally maladapted to novel fire patterns and post-fire climate conditions, large-scale shifts in conifer forest structure, composition, and extent may occur as warming intensifies. Forest resilience in the context of fire and climate can be understood and quantified by the survival of trees through fire events and success of trees to regenerate post-fire and maintain population levels. In this dissertation, I use field observations and remote sensing to …

Reducing Transphobic Attitudes: A Cross-National Investigation Of College Students In Japan And The United States, Kazusa Seko

Dissertations and Theses

Transgender people routinely experience discrimination and mistreatment. Although transphobic attitudes vary from country to country, a more in-depth understanding of these attitudes is needed. Using a semi-structured online survey, this study investigates college students' attitudes toward transgender people in Japan and the United States, a cross-national comparison that aims to deepen our understanding of how transphobic attitudes are shaped and what opportunities exist to reduce transphobia amongst college students. Results show that Japanese students express more transphobic attitudes than U.S. students do; and that U.S. students had more experience with gender-based educational content and were more likely to know someone …

The Relationship Of L2 Proficiency And L1 Reading Academic Performance Prior To Formal L1 Literacy Instruction In Foreign Language Immersion Settings, Andrew David Mckay Jr

Dissertations and Theses

The purpose of this study is to explore the statistical nature of the linguistic interdependence hypothesis (Cummins, 1976, 2017) in the spring of 2nd grade of students in foreign language immersion programs. Specifically, the interdependent relationship between L2 language proficiency levels and L1 reading academic performance in an environment where L1 is the majority language and L2 is the target language for instruction with students who have yet to receive formal reading instruction in the L1. The Continua Model of Biliteracy was used to frame the existing research on language acquisition. An experimental ex post facto design using archival data …

Exploring The Potential Use Of Porous Silica Nanoparticles In Cest-Mri, Lydia Makotamo

Dissertations and Theses

Magnetic resonance imaging (MRI) is a widely used modality in diagnostics, treatment, and monitoring various conditions due to its ability to generate high-resolution images using non-ionizing radiation. The advent of contrast agents, which generally work by increasing the spin relaxation rate constants of water protons, has led to image enhancement. Despite the usefulness of this class of agents in diagnostic medicine, their inability to provide in-depth functional and anatomical information, coupled with their high detection limits, has led to new agents being explored.

Chemical exchange saturation transfer (CEST) presents an alternative route to generate signals via repetitive saturations transfers between …

Community College Geoscience Faculty Perspectives On Critical Thinking Instructional Tools, Mariela Salas Bao

Dissertations and Theses

Research has shown that modern courses and programs designed to foster critical thinking vary in both content and delivery, in turn leading to differences in their effectiveness. Few studies have investigated critical thinking among nontraditional students at community colleges taking STEM courses, especially within the geosciences. Furthermore, such research has focused primarily on the students with few if any studies involving faculty. This study examined the perceptions held by community college geoscience faculty regarding critical thinking and how such perceptions influenced their choice of instructional strategies. This study used a basic qualitative methodology and a maximum variation sampling to select …

"It's Not By Accident": Examining Leadership Efforts To Disrupt Oregon's Segregated K-12 Education System, Michael Eric Salitore

Dissertations and Theses

The American education system systematically and persistently excludes students from the general education setting based on (dis)ability. Disproportionate segregation of students with Intellectual Disability (ID) is a form of prejudice that is acceptable today and allowable by current laws. Fully segregated education settings for students with ID are harmful to students with disabilities, to their neurotypical peers, and to civilized society as a whole. For many students with ID, ableist systems, deficit thinking, and special education rules allow for segregated placements to persist, impacting their pathway to accessing the general education curriculum.

Designing Environmentally Responsible And Highly Effective Bioorthogonally Functionalized Chiral Mri Contrast Agents, Karley Breann Maier

Dissertations and Theses

Magnetic resonance imaging (MRI) revolutionized diagnostic imaging and modernized the characterization of numerous diseases. The clinical success of MRI is in large part due to the employment of gadolinium-based contrast agents (GBCAs). Due to sensitivity limitations, GBCAs are indicated at markedly high dosages (~1 g Gd³⁺ per exam). The routine use of such large quantities of gadolinium poses significant health and environmental risks. There are growing concerns over the effects of dechelation of the metal in vivo and the possible effect of resulting gadolinium deposition. Concurrently, there is a rising awareness of gadolinium anomalies borne by GBCAs which undergo …

Mothers' Drinking Motives, Sheila Kathleen Umemoto

Dissertations and Theses

Increases in women's excessive alcohol use are leading to concerns about a developing public health problem since, for women, it takes fewer years and lower doses to develop a range of alcohol-induced health problems. Maternal status is generally considered protective against alcohol use; however, this effect is weakened by multiple social role strain, leading to higher stress and negative affect, and subsequent coping-related alcohol use. Given that the majority of mothers with young children are working or looking for work (72.3%; BLS, 2021), it is likely that the combination of competing demands and expectations associated with multiple roles of parent, …

Situate: An Agent-Based System For Situation Recognition, Max Henry Quinn

Dissertations and Theses

Computer vision and machine learning systems have improved significantly in recent years, largely based on the development of deep learning systems, leading to impressive performance on object detection tasks. Understanding the content of images is considerably more difficult. Even simple situations, such as "a handshake", "walking the dog", "a game of ping-pong", or "people waiting for a bus", present significant challenges. Each consists of common objects, but are not reliably detectable as a single entity nor through the simple co-occurrence of their parts.

In this dissertation, toward the goal of developing machine learning systems that demonstrate properties associated with understanding, …

Creativity In Science, Engineering, And The Arts: A Study Of Undergraduate Students' Perceptions, Dildora F. Beaulieu

Dissertations and Theses

Creativity is widely recognized as being invaluable for human development and a crucial 21^st century talent. Preparing students for an uncertain and complex world requires that higher education promote students' imagination, originality, curiosity, and flexibility and build their capacity to take risks to try new approaches to problem-posing and problem-solving. However, little is known about how undergraduates enrolled in different disciplines view creativity. This quantitative study at a university in the northwestern United States assessed how undergraduate students in different academic disciplines responded to an instrument on creativity measurement developed by Dlouhy (2012). The study asked: How do undergraduates …

The Effect Of Viscosity On The Puddle Dynamics In Low Gravity Environment, Taif Hamed Saleh Al Juboori

Dissertations and Theses

Enormous liquid puddles are observed to jump spontaneously from non-wetting substrates when exposed to the nearly step-reduction in body force common to drop tower test facilities. The phenomenon is similar to the second half of terrestrial drop bounce experiments except that (1) the initial static equilibrium configuration satisfies the static contact angle condition, (2) the initial height of the puddle is limited to the capillary height, and (3), for drop tower test durations on the order of seconds, puddle volumes can be over 10⁴ times larger in mass (volume). The passive puddle jump mechanism provides a no-moving-parts deployment method …

Letitia Carson In Court: African American Women, Property, And Wages In The Pacific Northwest, Stephanie Marie Vallance

Dissertations and Theses

Letitia Carson arrived in Oregon from Missouri in 1845, accompanied by David Carson and their newborn child, a daughter named Martha. The Carsons settled in the Soap Creek Valley and took advantage of Oregon's Provisional Government's donation land claim program, living on 640 acres in the newly formed Benton County with Martha and a second child, a son named Adam, born a few years after arriving in Oregon. Within ten years, however, David would be dead and Letitia would be dispossessed of all property and belongings. A former slave, Letitia had little social standing in the new territory and no …

Determinant Factors Of Bicyclist Injury Severity At Signalized And Unsignalized Intersections, Apy Das

Dissertations and Theses

Bicycling is becoming increasingly popular in Oregon and the US in general due to its environment friendliness as well as health benefits. With Oregon's population projected to increase by more than 30% over the next 30 years, improving the safety of the transportation network for persons on bicycles is important. In Oregon, majority of the bicyclist crashes occur at intersections. This thesis seeks to identify the determinant factors that significantly impact bicyclist crash injury severity at intersections. A mixed logit framework that accounts for any unobserved heterogeneity in the data and allows the estimated parameters to randomly vary across observations …

Modeling Environmental Factors Related To Drought-Induced Tree Mortality Based On Lidar And Hyperspectral Imagery, Lauren Nicole Sharwood

Dissertations and Theses

Climate change is projected to bring more frequent and prolonged droughts, causing widespread forest die-off. Identifying tree mortality over large spatial extents in response to the most recent California drought will help forest managers and conservationists understand where there may be a greater likelihood of future die-offs. In order to find more at-risk areas, this study evaluated how interacting site-specific topographic, climate, substrate, and stand characteristics mediated tree mortality in the Central Sierra Nevada during the 2012-2016 drought. The author used lidar and hyperspectral imagery provided by the National Ecological Observatory Network to identify individual dead trees using the Random …

Mapping The Publics: The Production Of Spatial Knowledge And Public Interest, Paul Thomas Manson

Dissertations and Theses

Over the past decades, calls for comprehensively managing and planning ocean resources have emerged internationally and within the United States. Central to these calls is a drive to expand coastal and marine spatial planning with a particular focus on technologically mediated public involvement. These new public involvement technologies aim, more quickly and thoroughly, to solicit and analyze public values and existing uses of the coastal and marine environments. One particular technological innovation is the use of participatory geographic information systems (PGIS). These new tools allow for stakeholders, members of the public, and planning entities to collect, visualize, and interact with …

Investigating Values In Discourse: Ideals And Social Plans, Luke Edward Hanst

Dissertations and Theses

Social scientists argue that values enable group coordination. I explore two theories of values before turning to evidence provided by Amanda Gorman's inaugural poem, "The Hill We Climb." First, the paradigm of Shalom Schwartz describes values as transsituational goals which enable groups to coordinate action and evaluate the world. I argue the Schwartz paradigm zooms out from values into categories while I need a means to zoom in to understand values in discourse. I turn to the Pragmatic Prospection paradigm to elaborate the cognitive ontology of goals and to understand the function of language. I argue that values are shared …

Early Implementation Of A Standards-Based Mathematics Curriculum: Understanding Teacher Perspectives And Concerns, Karen Ann Prigodich

Dissertations and Theses

Standards-based mathematics curricula are intended to shape teachers' classroom instruction in alignment with the content and practices of the Common Core State Standards for Mathematics. Instructional leaders facilitating teachers' implementation of these curricula frequently offer a variety of resources and structures to support effective curriculum use, but teachers themselves do not always find these supports to be helpful. Because teachers' concerns vary, understanding teachers' own perspectives is an important starting place for aligning support with teachers' needs. This case study explored the concerns of teachers from three U.S. school districts during their first year of implementing Bridges in Mathematics, …

From Mdp To Alphazero, David Robert Sewell

Dissertations and Theses

In this paper I will explain the AlphaGo family of algorithms starting from first principles and requiring little previous knowledge from the reader. The focus will be upon one of the more recent versions AlphaZero but I hope to explain the core principles that allowed these algorithms to be so successful. I will generally refer to AlphaZero as theses [sic] core set of principles and will make it clear when I am referring to a specific algorithm of the AlphaGo family. AlphaZero in short combines Monte Carlo Tree Search (MCTS) with Deep learning and self-play. We will see how these …

Japanese-English Code-Switching By Postwar Speakers In Contemporary America, Andre John Shepherd

Dissertations and Theses

In her examination of Japanese-English bilingualism in Toronto, Nishimura (1995b) demonstrated that second-generation Japanese-Canadians varied their speech dependent on the audience they were addressing. According to her, the Japanese-Canadians spoke primarily in English to fellow second-generation speakers, while maintaining conversations in Japanese with those who had spent their formative years in Japan. However, when addressing audiences composed of both groups, they switched back and forth evenly between the two languages.

Following research done by Woolard (1989) on the effects of societal influences on language, the state of the Japanese-Canadians can be related to the breakup of the ethnic enclaves in …

The Longitudinal Effects Of A Family And Sleep Supportive Intervention On Service Member Anger And Resilience, Shalene Joyce Allen

Dissertations and Theses

The vast majority of workplace intervention research on employee anger and resilience primarily focuses on individual-level strategies for mitigating employee anger and resilience outcomes in the workplace, with no studies having examined these outcomes with tangible occupational health interventions utilizing organizational-level techniques. Thus, the current study extends the literature on how to provide improvements in employee anger and resilience using higher system and organizational change mechanisms by providing evidence-based support for the effectiveness of a Total Worker Health® intervention, referred to as the Family and Sleep Supportive Intervention Training (FaSST). This approach employs both health protection and health promotion strategies …

God-Talk In Catholic High Schools: Theology Teachers Doing Theological Education For And With Religiously Diverse Student Populations, David Michael Avram Gregory

Dissertations and Theses

High school students deserve educations that honor and respect their cultural positionalities, of which religious beliefs are frequently an integral part. Almost 25% of students in Catholic high schools identify as non-Catholic, but the U.S. Catholic bishops have mandated that Catholic secondary theological education (through their 2008 Doctrinal Elements of a Curriculum Framework for the Development of Catechetical Materials for Young People of High School Age) be catechetical. In writing and promulgating this document, the bishops presupposed that Catholic schools' students are Catholic, or (should) desire to become Catholic. For decades, scholars have critiqued catechesis as an inappropriate mode …

The Discourse/Pragmatic Functions Of Japanese Okkē, Peter Fodor

Dissertations and Theses

Okay is one of the most commonly used words in the English language. It is also one of the most commonly borrowed English-origin loanwords across all of the world's languages. Although there is a wealth of research on the communicative functions of English okay, there is comparatively little research on the many borrowings of the word in various other languages. In order to address this gap in the literature, this study explores the differences in discourse/pragmatic function between the English word okay, and the Japanese borrowing of the word, okkē.

Extensive research in discourse analysis, pragmatics, and …

A Bioinformatic And Biochemical Analysis Of Cruciviruses, George William Kasun

Dissertations and Theses

Cruciviruses are novel ssDNA viruses discovered through metagenomics and direct environmental DNA amplification and cloning. The genomes of cruciviruses suggest that gene transfer between RNA and DNA viruses occurred due to the presence of putative protein-encoding genes that are homologous to both ssRNA and ssDNA viruses. In order to gain a better understanding of this group of viruses both bioinformatic analyses and in vitro biochemical experiments were employed. The results of the bioinformatic analyses show that cruciviruses are a highly diverse group of ssDNA viruses. Their placement within established ssDNA phylogenies is difficult due to heterogeneity in their putative replication-associated …

What Does It Mean To Be Deaf? Changing Meanings Of Deafness, Communication Technology, And Beliefs About Normality In The Us, Kathryn Elizabeth Burrows

Dissertations and Theses

How deafness is perceived as a problem by society dictates what types of technologies are leveraged to address the problem, and, conversely, available technologies shape how deafness is perceived. In this dissertation, I draw on multiple methods to explore the meanings of deafness in the US since the early 18^th century to the present, examine how the meanings of deafness in those eras shaped deaf technology, and assess how available technologies shaped how deafness was understood. Using primary and secondary historical sources, I identify that every era identifies a different "problem of being deaf" and it is that problem …

Guarding Against Strain: The Moderating Role Of Nonwork Experiences In The Relationship Between Work-Related Hypervigilance And Strain In Correctional Officers, Samantha Getzen

Dissertations and Theses

Correctional officers (COs) are expected to remain alert in order to maintain safety within the potentially hostile prison environment. As a result, COs experience high levels of work-related hypervigilance (WHV), which has been associated with negative health and wellbeing outcomes for COs. This study examines nonwork experiences as potential boundary conditions for the relationship between WHV and strain outcomes. It was hypothesized that nonwork experiences (psychological detachment, relaxation, mastery experiences, and exercise) would weaken the relationship between WHV and strain outcomes (emotional exhaustion, physical symptoms and impaired sleep). Data were analyzed from 166 COs in Oregon. A series of hierarchical …

Improving Bicycle Crossings At Unsignalized Intersections Through Pavement Markings: Analysis Of The City Of Portland Innovative Strategy, Frank Boateng Appiah

Dissertations and Theses

The increasing trend in the number of bicycle crashes in the U.S since 2009 has been a major challenge to safety. In 2019, a total of 36,096 people were killed on U.S roadways. A total of 846 (2.3%) of these fatalities were bicyclists and around 75% of the bicycle fatalities occur in urban areas and intersections are common locations of crashes. Many bicycle enhancements such as bike boxes, bicycle signals, curb extensions have been installed to improve safety at signalized intersections. The City of Portland OR experimented with an innovative treatment to improve bicycle crossings at unsignalized crossings. This treatment, …

Building A Biomechanical Model Of A Rat Forelimb, Joshua Nathaniel Eric Mak

Dissertations and Theses

This paper presents a biomechanical model of the rat forelimb to test theories of determining viscoelastic muscle parameters. Several biomechanical models of rat hindlimbs have been developed and have explored the effects of multi-muscle control during locomotion. The forelimb model uses two ball-and-socket joints to model clavicle and scapula movement. A third ball-and-socket joint is used at the shoulder and two hinge joints are used at the elbow and wrist. Scapula motion is further constrained by muscle and spring elements. Each forelimb has 11 degrees of freedom, and 23 Hill-type muscles. The model has been created in Animatlab, which includes …
