Statistical Analysis Of Social Network Change, Teresa Danielle Schmidt

Dissertations and Theses

This project explores two statistical methods that infer social network structures and statistically test those structures for change over time: regression-based differential network analysis (R-DNA) and information theory-based differential analysis (I-DNA). R-DNA is adapted from bioinformatics and I-DNA employs reconstructability analysis.

This project applies both R-DNA and I-DNA to analyze Medicaid claims data from one-year periods before (May 2011- Apr 2012) and after (Jan 2013-Dec 2013) the formation of the Health Share of Oregon Coordinated Care Organization (CCO). The formation of CCOs was legislated by the state of Oregon in 2012 with the triple aim of improving health outcomes, reducing …

Bone Mineral Density Of The Common Bottlenose Dolphin, Tursiops Truncatus: A Proposed Model For Monitoring Osteological And Ecosystem Health, James Wright Burrus Powell

Dissertations and Theses

Bone mineral density (BMD) in the pectoral flipper of the common bottlenose dolphin, Tursiops truncatus, was examined to address the need to define a comprehensive target site for clinical osteodensitometric assessment and to establish ranges of observed bone density values for this species. Radii were analyzed using dual energy X-ray absorptiometry (DXA), the accepted standard in human medical studies. Multiple loci within the radius were identified and assessed for their correlation to BMD of the entire bone. Radii BMD were also examined for differences based on sex, age, total body length, handedness, geographical affinity, and nutritional status at time …

Recruitment Marketing: How Do Wellness And Work-Life Benefits Influence Employer Image Perceptions, Organizational Attraction, And Job Pursuit Intentions?, Amy Christine Pytlovany

Dissertations and Theses

A global talent shortage is motivating employers to change the way they approach recruitment. To stay competitive, business leaders are strategizing new ways to attract employees and market their organizations to prospective employees. This research examined the impact of work-life and wellness programs on employer image perceptions (instrumental, symbolic, and experiential) and recruitment outcomes (organizational attraction and job pursuit intentions). It integrated these literatures to inform evidence-based organizational decision-making.

Study materials were developed with pilot testing conducted using Amazon Mechanical Turk (MTurk). Pilot 1 (N = 40) assessed the value of 32 types of benefits across traditional (e.g., health …

Believe Our Stories & Listen: Portland Street Response Survey Report, Greg Townley, Kaia Sand, Thea Kindschuh

Psychology Faculty Publications and Presentations

Many advocates, local officials, and people experiencing homelessness agree that Portland needs a better way to respond to low-priority calls for service involving those experiencing homelessness and behavioral health crises. This report examines efforts to address homelessness in Portland through the development of a plan to dispatch the Portland Street Response unit rather than police.

A team of community partners spread out across the city July 16 and 18 to interview people experiencing homelessness to help inform the design of the Portland Street Response pilot project (PSR). An additional team went out on Sept. 6.

Hiv, Stigma, And Attribution Of Causal Emotions, Zoe Elizabeth Larson

Dissertations and Theses

Stigmatization of people living with HIV/AIDS is considered a major barrier to the treatment and prevention of HIV/AIDS. Attribution theorists have examined stigmatizing attitudes as a product of causal emotions; to wit, people face greater judgment and stigmatization when their actions are perceived as controllable and less stigmatization when actions are perceived as out of the realms of personal control. The current study examined attribution of causal emotions for three different circumstances of HIV acquisition, which varied in their perceived controllability. The results showed statistically significant differences in participant evaluations of responsibility, blame, and anger. Statistically significant correlations were found …

Radical Doulas Make "Caring A Political Act": Full-Spectrum Birthwork As Reproductive Justice Activism, Jadee Yvonne Carathers

Dissertations and Theses

This study, based on in-depth interviews with 30 self-identified radical doulas working in the US, describes the radical practices, positionality, and orientation towards reproductive justice that distinguish these care workers from mainstream doulas. Radical doulas provide nonjudgmental support in a full-spectrum of reproductive experiences from menarche to menopause according to the needs of their clients. As non-medically trained care workers, they provide informational, emotional, and physical support during abortion, birth and postpartum, fetal loss, adoption, or surrogacy, enacting individualized skill sets across settings from homes to hospitals and clinics. Radical doulas are paid professionals, but often offer a sliding-scale for …

Impactful Care: Addressing Social Determinants Of Health Across Health Systems, Nicole Lisa Friedman

Dissertations and Theses

There is emerging evidence that addressing health-related social needs through enhanced clinical-community linkages can improve health outcomes and reduce costs. Unmet health-related social needs, such as food insecurity, inadequate or unstable housing, and lack of access to transportation may increase the risk of developing chronic conditions, reduce an individual's ability to manage these conditions, increase health care costs, and lead to avoidable health care utilization. In response, work on social needs is happening across large health systems in the United States, but the pace of progress is slow and accountability is diffuse.

The goal of this applied research project is …

A Retrospective Chart Review Of Sleep Questionnaires In Children With Down Syndrome, Sarah Therese Florig

University Honors Theses

Introduction: Despite the high prevalence of obstructive sleep apnea (OSA) in children with Down syndrome (DS), very few subjective pediatric assessments have been evaluated in this population. The Sleep-Related Breathing Disorder subscale of the Pediatric Sleep Questionnaire (SRBD-PSQ) and Obstructive Sleep Apnea-18 Quality-of-Life Questionnaire (OSA-18) are two sleep-related questionnaires previously validated for the general pediatric population. Our aim was to assess the performance of these questionnaires in our DS population.

Methods: We performed a retrospective case series of patients with DS, ages 2-18 years, seen in our tertiary care DS clinic between May 1, 2009 and October 1, 2018. We …

Medicaid Patients' Use Of Dental Benefits, Merit Roshdy

University Honors Theses

Oregon Health Plan patients experienced reduction to their dental coverage in 2003. This study explores Medicaid patients’ use of those dental services that are still offered to them and the effect of their use on self-assessment of their oral health. A phone survey was conducted in 2017 and collected a sample of 293 Medicaid patients in Oregon. Only two thirds of participants reported that they have a regular dentist. Participants were more likely to rate their overall health as Excellent/Good when also rating their gum health as Excellent/Good. Low English Proficiency (LEP) patients were NOT less likely to visit their …

Species Diversity In The Hypertragulid (Mammalia: Artiodactyla) Population Of The John Day Basin, Oregon, Lana K. Jewell

University Honors Theses

Members of the family Hypertragulidae (order Artiodactyla, class Mammalia) are the most abundant mammals in the Turtle Cove Member (Oligocene) of the John Day Formation of central and eastern Oregon and make up about 40% of the preserved specimens of the John Day Basin. Three species and two separate genera are described in the area, but any preexisting research lacks statistical support for this level of variation. Species designation among extinct artiodactyls is predominantly based on morphological and morphometric examination of dentition, but studies conducted with extant artiodactyls have revealed that this may not be a reliable diagnostic technique. Other …

The Use Of Aromatherapy For The Treatment Of Post-Operative Nausea Vomiting, Mikayla J. Whitley

University Honors Theses

Post-operative nausea vomiting (PONV) is one of the most common complications after surgery and a significant cause of dissatisfaction among post-operative patients. Traditional first line treatment of PONV with antiemetic medications can cause severe side effects and can have compounding interactions with other medications. Aromatherapy has been increasing in popularity for the treatment of PONV due to its safety, absence of drug interaction and side effects, and rapid onset due to ease of administration and patient driven treatment. This study looks at a trial of QueaseEASE, an aromatherapy product for PONV, at a hospital in the Pacific Northwest. Overall initial …

Healthcare Spending Mandate Modeling Report, Northwest Economic Research Center, Peter Hulseman, Adam Rovang, Devin Bales, Nicholas Chun

Northwest Economic Research Center Publications and Reports

Governor Brown’s health care financing package, which was released with the 2019-21 recommended budget included several revenue components which provide broad-based, sustainable revenue for health care coverage in Oregon for the next six years. One component of that package is the Subsidized Employer Participation Program, which would be similar to the San Francisco Health Care Security Ordinance (HCSO). The new requirement would compel employers of a certain size who otherwise do not qualify for any exemption to contribute to their employees’ health care costs. An employer’s contribution could be in one of three ways: (1) in the form of directly …
