Gi Zoonoses In Companion Pets Of The Homeless : The Effects Of Environment And Behavior On The Prevalence Of Gi Parasites, And The Role Of Veterinarians In Public Health Education, Matthew Edwards

University Honors Theses

Veterinarians are the front-line in the world of pet-health and zoonoses which means they are also at the front-line of human health and have an important role of educating clients on behaviors that would both reduce the risk of human and pet contracting a disease. In this study we collected 85 stool samples in Portland OR, USA and examined these by centrifugal fecal flotation, direct smears and for a small number (n=15) ELISA snap-tests. Parasitic prevalence was found to be 27.1% total including 2.4% Ancyclostoma Sp., 4.7% Cryptosporidium Sp., 7.1% Cystoisopora Sp., 9.4% Taenia Sp., 2.4% Giardia Sp., and 2.4% …

Following two collaborative manifestos of graphic designers discussing design's potential outside of the commercial realm, this paper examines the way that graphic design has assisted with environmentalism thus far and makes a proposal for the way that graphic design should be used in an environmentally sustainable context into the future. Using the tenets of the new scholarly realm of Transition Design, this paper dissects how graphic design can assist a transition away from a …

Psychology At A Distance: Examining The Efficacy Of Online Therapy, Ryan Baird Thompson

University Honors Theses

Online therapy presents both potential benefits, and possible hazards, when compared with traditional face-to-face (FTF) therapy. Questions of clinical efficacy are of primary interest to mental health workers and researchers. In this literature review, I break the concept of efficacy into a tripartite investigation of outcome, process, and self-report evidence. The outcome evidence indicates that teletherapy patients experience similar results compared with control groups. The process studies indicated that working alliance was unaffected by the medium of communication. Finally, the survey studies reported that clients were predominantly satisfied with online therapy. Therapists, however, had misgivings about the online therapy environment. …

Use Of Behavioral Activation Theory To Identify Depression Among Hiv-Positive Women Of Color In The Rural South, Tascha R. Johnson

University Honors Theses

Women of color (WOC) are disproportionately affected by the HIV epidemic in the Southern United States and are at increased risk of infection, mortality and being lost to care. It has been found that compared to Whites, WOC are more likely to have more negative views towards mental illness and are less likely to seek help. The research presented here considers how depression acts as a barrier to health care and discusses the challenge that WOC face in identifying and naming depression. The Behavioral Activation Theory, posits that women may show depression through their behaviors even if they don’t explicitly …

University Honors Theses

Research on the experiences of transgender and gender nonconforming individuals is increasing, and this qualitative sociological study aims to build an understanding of trans* experiences on public transit and their experiences in the unique form of public space the confined space of the city bus and light rail train. I seek to amplify trans* voices, inform trans-inclusive transit policy, and add to conversations on how gender operates in urban and public spaces by contributing perspectives of transgender and nonbinary individuals.

Gender, Networking, And Transnationalism: A Case Study From Dakar, Senegal, Sarah Akin

University Honors Theses

Nongovernmental organizations have become important actors and contributors to global governance as states have been superseded as the primary representatives of constituents. Many of the current studies on NGOs tend to focus on their abilities as institutions without actually studying the processes that occur in the work. The current trend in the literature is moving beyond a generalization of NGO work that provides binary accounts of success and failure, good and bad toward ethnographic approaches that study the processes of NGOs in time and space. It is argued that development NGOs, particularly those that work on issues of gender and …

An Examination Of Approaches To Domestic Violence Advocacy: Recommendation For Generalizable, Experimental Study, Melanie Stewart

University Honors Theses

Only since the 1970s has there been societal interest in establishing Domestic Violence (DV) advocacy to address the violent oppression of women. The catalyst which brought this issue to the forefront of social consciousness was the Women's Liberation Movement. The activism of the 1960s civil rights movements set the stage for the Battered Women's Movement. Feminists recognized violence as a product of patriarchal society. Patriarchy, and with it personal and institutional violence, was embedded in every aspect of society. Shifting ideological and political views have influenced the evolution of DV advocacy from the grassroots activists’ fight for equality, to the …

Rewriting History: Using Reconciliation Processes To Revise Dominant Cultural Narratives And Assessing Cultural Readiness For Reconciliation, Flannery Mack

University Honors Theses

Truth and Reconciliation processes are key to rebuilding societies damaged by broad-based, government-sanctioned violence by revising dominant cultural narratives of the violence. In Indonesia, there has been no such process following the killings of between 500,000 and 2 million suspected communists in 1965-66. This paper is an exploration of conflict transformation theory, and of what form a truth and reconciliation process might take in Indonesia following 50 years of impunity. Using Joshua Oppenheimer's 2012 and 2014 documentaries The Act of Killing and The Look of Silence as primary reference points, I use critical discourse analysis to look at how the …

Fitness And Fatness: The Conflation Of Weight With Health, And The Consequences Of Fat-Shaming, Kristin Spurkland

University Honors Theses

Obesity is widely accepted as one of the major health crises facing the United States, and increasingly, the world. Labeled a disease by the American Medical Association, and frequently characterized as an epidemic, obesity is the target of high profile national health interventions, media campaigns, and a multi-billion dollar self-help industry. The message produced by public health agencies is that obesity is a killer, and that reducing weight is a beneficial and achievable goal generating many positive health outcomes. This paper presents two primary arguments that counter the prevailing attitudes towards obesity: that as a stand-alone measure, Body Mass Index …

The Russian-German Exiles In Kazakhstan: 1940 & 1990 Migrations, Irina Rudenko

Organized into two parts: the first half concentrates on the 1940 deportations and the second half on the 1990 migrations. The journey of the 1940 Soviet deportations is studied through parallels of the government’s intentions juxtaposed with the realities on the ground. Then a literature review of work done by scholars in the Soviet archives discusses the common consensus in regards to claims of Soviet ethnic cleansing and genocide. An overview of the documented realities of exile confronted by the deportees supplements …

Gun Control In The United States: An Analysis Of Federal And International Policies And Applications, Claire Hummer

University Honors Theses

This paper will examine past and present U.S. gun control policies to better understand the current legal state of gun control, but also to assess gun culture in a nation that was built on its Second Amendment right to bear arms. In addition to U.S. policy, international agreements and gun control policies in other countries will also be analyzed to determine if those policies would be feasible in the U.S., or if the country’s gun culture and legal precedents would simply strike down any attempt to establish more thorough regulations.

Animal Hoarding: An In Depth Look At The Issues And Interventions, Amanda Mooneyham

University Honors Theses

Animal hoarding cases in regard to 501(c)3 nonprofit agencies have been on the rise in recent decades and current intervention strategies are struggling to address this complex social problem. Animal hoarding not only affects the animals being abused, but it has adverse effects on humans and the environment. This paper examines the complexities surrounding animal hoarding, specifically focusing on the rescue hoarder mentality. The current intervention methods used are criminal prosecution, civil/regulatory enforcement, and mental health evaluations/treatments. Criminal prosecution is effective for some animal hoarders, but a lack of laws protecting animals along with animals being viewed as property translates …

Cost Of Commuting: A Review Of Determinants, Outcomes, And Theories Of Commuting-Related Stress, Damon M. Holland

University Honors Theses

Commuter-related stress, its history, associated determinants, outcomes in work environments and theoretical and methodological approaches were examined. In this cross-disciplinary review, I synthesize the research findings on commuting-related stress as it relates to workplace outcomes. In the extant literature, control, predictability, impedance, and length of commute are commonly associated with commuter stress. In addition, prior research has identified workplace aggression and absenteeism as prominent work-related outcomes of commuter stress.

The Controversy Over Community Water Fluoridation : An Analysis Of Its Effects And Reasons Behind The Arguments, Grace Noda

University Honors Theses

This thesis explores different viewpoints on the history of community water fluoridation and reflects on the arguments made by the pro- and anti-fluoridationists in the United States. Community water fluoridation has been controversial in the United States since it was first proposed in 1945. Since then, fluoridation has been a major factor in reducing the prevalence and severity of dental cavities in the United States (U.S.).

Fluoride safely and effectively prevents dental cavities and is available from multiple sources. Community water fluoridation is one of these sources, providing fluoride to all people regardless of their position within the community. Even …

Physician Quality Reporting System: Initiative To Improve Care For Medicare Beneficiaries, Sara Smith

University Honors Theses

The Centers for Medicare and Medicaid Services (CMS) developed the Physician Quality Reporting System (PQRS) in response to congress mandating quality improvements for Medicare beneficiaries. This program has been heavily criticized for its cost, lack of provider participation and poor reception. However, recent reports show the PQRS has produced some quality improvements. Since PQRS will continue to be used in its current form through 2017 and will be incorporated into a new program starting in 2018, it is necessary to assess the weakness and strengths of this program. Addressing these are crucial for the successful continuation of PQRS and improving …

Fathering Interventions For Men Who Use Intimate Partner Violence And Child Maltreatment: Perceived Benefits And Risks, Aaron L. Brown

Intervention classes for fathers that use family violence are in the very early stages of development. The purpose of this paper is to better understand how fathering interventions are minimizing risks and maximizing benefits in working to address the service and knowledge gaps toward father’s that use IPV, CM, or both IPV and CM. Initially, the service and knowledge gaps are identified as well as the perceived benefits and risks of offering fathering interventions. Then, based on the analysis, several recommendations are made for the implementation of these interventions. Following this, I describe two widely available intervention curricula, and discuss …

Determining The Relationship Between White Matter Volume And Processing Speed In Adolescence, Julius Laxamana

University Honors Theses

Neuroimaging techniques have recently been used to research and identify relationships between structure and function. Because adolescence is a critical period for development of the brain, the present study’s goal was to identify the possible relationships between white matter (WM) volume and processing speed during this period. White matter was of particular interest as it consists of the myelinated axons of some nerve cells which are essential for nervous system functioning. The WM volume of 157 adolescents (ages 12-17) were determined from T1-weighted images via FMRIB’s Automated Segmentation Tool (FAST), whereby the brain was separated into WM, gray matter (GM), …

Expression And Purification Of Recombinant Protein To Generate A Monoclonal Antibody To The Px Domain Of Tks5 Α Isoform In Cancer Cells, Eva Y. Chan

University Honors Theses

Tyrosine kinase Src substrates, Tks4 and Tks5, are involved in the formation of podosomes and invadopodia during cell migration and cancer cell metastasis. Most recently, the α isoform of Tks5 has been discovered highly expressed in cancer cells, suggesting that the Tks5 α isoform plays essential roles in the regulation of invadopodia. In the Tks protein family, only the Tks5 α isoform contains a PX domain, which binds an important second messenger, PI (3,4) P2. Using a monoclonal antibody as an antigen-specific-probe to detect the protein of interest could be a useful tool that would provide a highly specific recognition …

Attitudes Among Legal Professionals: Measuring For A Difference In Attitudes Towards Science, Jonathen N. Gates

University Honors Theses

Media provides an image of science, as used by law, in an unflattering light. Scientific experts are portrayed as misrepresenting and obscuring the truth of research to support a position at the behest of lawyers and their clients. This research examines the occurrence of "junk science" in courts and relates doctrinal and values theories to explain its presence. An investigation of attitudes towards science is conducted using General Social Survey data to test whether legal professionals hold more negative views towards the scientific community than peers in other fields. The regressions suggest that legal professionals may in fact have more …

Self-Infantilizing Women: Paternalism In Abortion Lawmaking And Legislator Gender, Cherie H. Martin

University Honors Theses

Mainstream feminist political science discourse primarily focuses on abortion as an issue of male dominance over female individuals, and little research has been conducted to determine whether female lawmakers, too, are complicit in paternalism in anti-abortion rhetoric and lawmaking, and the implications of such self-infantilization. The present thesis surveys the existence of paternalistic language in state-level anti-abortion bills for the 2016 legislative session, and analyzes the results by legislator gender. The data conveys that both male and female legislators employ paternalistic language in anti-abortion legislation, which implies there is more to the abortion debate than gender differences. This paper explores …

"Like A Parasite Dozing In The Gut": Idleness And Tending In J.M. Coetzee's Life And Times Of Michael K, Patrick Barrett

University Honors Theses

This paper will attempt to articulate how idleness functions in J.M. Coetzee’s 1983 novel Life and Times of Michael K, and to analyze how it might be undermining or commenting on the idea of idleness which was discursively produced in South Africa in the 17th and 18th centuries. Coetzee develops a commentary on the European representation of idleness in his book White Writing: On the Culture of Letters in South Africa, which for my purposes will serve as a jumping off point for a reading of Michael K. Furthermore, I will seek to examine the ways in which idleness does …

Cofactor Binding Determinants In The Nadph-Dependent Nitrile-Oxidoreductase Quef, Spencer William Cohen

University Honors Theses

The NADPH-dependent nitrile-oxidioreductase, QueF is the only known enzyme capable of reducing a nitrile group to an amine. This ability makes it an attractive alternative to conventional industrial nitrile reduction. Understating how QueF binds NADPH may lead to the development of an enzyme capable of using the less expensive reductive cofactor NADH. A cofactor docking model indicates that key residues, Q60 and Y21, interact with the ribose phosphate moiety unique to NADPH. Mutants of these residues (Q60A, Q60N, Q60E, Y21A and Y21F) were developed for steady-state kinetic analysis. Modification to either residue resulted in a decrease in binding and catalytic …

Fetal Stress And Neurogenesis In Thamnophis Sirtalis Parietalis, Kalera Stratton

University Honors Theses

Little is currently known about normal brain development and the growth of new nerve cells, known as neurogenesis, in most species, let alone how exposure to prenatal stress affects these processes. Using red-sided garter snakes as our animal model, we have a unique opportunity to study the impact of exposure to elevated maternal glucocorticoids, commonly known as "stress hormones", on brain development. This species is viviparous, with a proto-placental structure through which developing fetuses receive nutrients from the dam. Adult snakes also exhibit high rates of seasonal changes in neurogenesis. We captured mated female snakes and treated one-third of them …

Review: A Novel Multiple Sclerosis Model Utilizing Cuprizone And Rapamycin, Mara Bahri

University Honors Theses

Multiple Sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system leading to debilitating long-term neurologic damage, primarily due to the limited ability of remyelination in the adult human brain. This review summarizes the current knowledge regarding the combined administration of Cuprizone (CPZ) and rapamycin as a novel animal model for MS. Utilization of CPZ induces non-immune mediated demyelination, therefore bypassing complexities of the immune system and allowing analysis of de-/remyelination. Furthermore, remyelination occurs simultaneous with demyelination due to ongoing oligodendrocyte progenitor cells (OPCs) differentiation into mature oligodendrocytes (OLGs).

The immunosuppressive agent, rapamycin inhibits the regulatory pathway Akt/mTOR, …

Following The Flat Hat: What Leads People To National Park Service Interpretive Careers?, Avarie Fitzgerald

University Honors Theses

National Park Service interpreters around the United States are dedicated to connecting people to their parks and historical sites. While these interpretive rangers have an important mission of preserving the landscape and stories of our nation’s most treasured places, a gap in the research of significant life experiences and environmental education professions exists in understanding the motivations behind following a career in the park service. Through semi-structured phenomenological interviews, the significant life experiences of interpretive park rangers were investigated as to their degree of influence on their choice of career. The findings indicate that quality time spent outdoors, family involvement, …

Mindfulness-Based Stress Reduction (Mbsr) As An Alternative Therapy For Chronic Pain, Kayla Ohlgren

University Honors Theses

This thesis discusses the possibility of Mindfulness-Based Stress Reduction (MBSR) as an alternative therapy for chronic pain in contrast to traditional medical care. It examines 18 peer-reviewed scholarly articles and identifies benefits for chronic pain patients in terms of pain severity, quality of life, psychological distress, and duration of benefits. This thesis also identifies practical benefits of MBSR such as cost, implementation, no negative side effects, and the creation of life-long skills to be used after treatment has ended. In conclusion, there is a significant gap in the current academic literature pertaining to chronic pain patients who are minorities, men, …
