OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Hikikomori is a severe form of social withdrawal, originally described in Japan but recently reported in other countries. Debate exists as to what extent hikikomori is viewed as a problem outside of the Japanese context. Objective: We aimed to explore perceptions about hikikomori outside Japan by analyzing Western language content from the popular social media platform, Twitter. Methods: We conducted a mixed methods analysis of all publicly available tweets using the hashtag #hikikomori between February 1 and August 16, 2018, in 5 Western languages (Catalan, English, French, Italian, and Spanish). Tweets were first classified as to whether they described …

Relative Wealth, Subjective Social Status, And Their Associations With Depression: Cross-Sectional, Population-Based Study In Rural Uganda, Meghan L. Smith, Bernard Kakuhikire, C. Baguma, Justin D. Rasmussen, David Bangsberg, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Depression is a leading cause of disability worldwide, and has been found to be a consistent correlate of socioeconomic status (SES). The relative deprivation hypothesis proposes that one mechanism linking SES to health involves social comparisons, suggesting that relative SES rather than absolute SES is of primary importance in determining health status. Using data from a whole-population sample of 1,620 participants residing in rural southwestern Uganda, we estimated the independent associations between objective and subjective relative wealth and probable depression, as measured by the depression subscale of the Hopkins Symptom Checklist (HSCLD). Objective relative wealth was measured by an asset …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Effective administration of tuberculosis therapy remains challenging. The recommended strategy of direct observed therapy is challenging and its implementation has been limited in many settings. Digital adherence technologies could be promising patient-centered strategies for monitoring adherence. However, few quality studies have assessed patients’ experiences with these technologies. Objective: To explore TB patients’ perceptions of a digital adherence intervention composed of a digital adherence monitor and SMS texts. Methods: We purposively sampled TB patients who owned phones, had been taking TB medication for at least a month, and were receiving their treatment from Mbarara Regional Referral Hospital. We interviewed 35 …

Words Matter: Putting An End To “Unsafe” And “Risky” Sex, Julia L. Marcus, Jonathan Snowden

OHSU-PSU School of Public Health Faculty Publications and Presentations

Change is constant in sexual health, as in health care more broadly. Novel pathogens are identified, epidemics emerge and reemerge, and new preventive and therapeutic agents are introduced and taken up by populations. On the other hand, some care strategies and practices fall by the wayside among clinicians and populations. Just as health and health care evolve, so too should the language that we use to describe them.

In this commentary, we express our concerns about the use of ambiguous and stigmatizing language when describing sexual behavior. A search on PubMed in September 2019 yielded over four thousand articles with …

Emergent Regulatory Systems And Their Challenges: The Case Of Combination Medical Products, George Horvath

Faculty Scholarship

Where regulatory systems overlap, courts and scholars often focus on the undesirable aspects of the overlap—the ways in which systems conflict. One such context involves the regulation of prescription drugs and medical devices by the FDA’s premarket evaluation processes and by state common-law tort and products liability actions. FDA regulation and state common law are often described as separate, conflicting regulatory systems. This Article challenges that description by proposing a model in which FDA premarket evaluation and state common law function as a single regulatory system.

This model brings order to the Supreme Court’s seemingly inconsistent medical products preemption cases, …

In The Name Of Merit: Racial Violence In The Academy, Reshmi Dutt-Ballerstadt

Faculty Publications

Racial violence in the academy is enacted upon faculty of color, particularly women, in multiple disciplines. This essay attempts to both expose and suggest that everyday systemic racism has become a pervasive and normalizing feature within disciplines that continue to privilege white and Eurocentric forms of knowledge-making while devaluing others. Furthermore, attempts to challenge such supremacies are immediately countered by calls and charges of incivility. This is an essay about the costs of unmasking norms of civility as it bears upon constructions of both whiteness and meritocracy.

This qualitative study used social constructivism as a theoretical lens to examine ways in which literacy teacher educators incorporate field experiences during literacy coursework. A cross-sectional survey was distributed among literacy teacher educators affiliated with teacher preparation programs located in a single Southern state. Responses related to field experiences were retrieved from 42 surveys and analyzed with two cycles of coding. Findings indicated that preservice teachers completed a range of field experiences prior to student teaching that involved observing literacy instruction and leading literacy instruction with individual students and small groups of students. Incongruences between reported field experiences and recommendations …

The Experiential-Learning Track: Career Exploration, Student Interest, & Applied Classroom-Learning In Small Rural Junior-Senior High Schools, Michael Turnlund

Northwest Journal of Teacher Education

Budgetary constraints can limit academic programs and elective offerings in small rural high schools. It is difficult to staff schools with teachers who hold the required credentials to offer elective courses that match student interests and future career or post-secondary education goals. This article details a strategy used by one small school in Idaho to address the problem. The Experiential-Learning Track Program allows for “hands-on” opportunities tied to learning objectives, and targets career and post-secondary education goals of individual students. Outcomes of the project included an increase in student population numbers and more connections with the local community.

Harnessing Sustainable Motivation: A Grounded Theory Exploration Of Public Service Motivation In Local Governments Of The State Of Oregon, United States, Sajjad Haider, Guoxian Bao, Gary Larsen, Muhammad Umar Draz

Public Administration Faculty Publications and Presentations

Employee motivation has always been a matter of concern for both public and private sector organizations. Since the industrial revolution in the late 18th century, organizations have struggled to foster workforce motivation and morale to enhance productivity. While a plethora of literature focuses on private sector motivation research, public sector organizations receive only modest scholarly attention. However, a new concept has emerged in public management literature during the late 1980s and 1990s, later known as public service motivation (PSM). The debate about PSM is premised on the notion that the motivation of public sector employees is quite different from their …

Modeling Changes In Public Transit And Private-For-Hire Usage When Implementing A Spatial Tax, Ty Lazarchik

REU Final Reports

Private-for-Hire (PfH) transportation options, such as Uber, Lyft, and taxicabs, are consistently growing in popularity. With this expanded utilization, cities are struggling to maintain usage of their public transit systems. While PfH transportation has been heavily researched, there is a need to further study how its effects on transit usage may be minimized. In this paper, previous work in traffic modeling and analysis of transit and PfH differences are expanded to develop an agent-based decision model in order to simulate and analyze the effectiveness of implementing a location-based tax in and around the city center of Portland, Oregon. The results …

Monitoring Annoyance And Stress Effects Of Wind Turbines On Nearby Residents: A Comparison Of U.S. And European Samples, Gundula Hübner, Johannes Pohl, Ben Hoen, Jeremy Firestone, Joseph Rand, Brian Elliott, Ryan Haac

Regional Research Institute for Human Services

As wind turbines and the number of wind projects scale throughout the world, a growing number of individuals might be affected by these structures. For some people, wind turbine sounds and their effects on the landscape can be annoying and could even prompt stress reactions. This comparative study analyzed a combined sample of survey respondents from the U.S., Germany and Switzerland. It utilized a newly developed assessment scale (ASScale) to reliably characterize these stress-impacted individuals living within populations near turbines. Findings indicate low prevalence of annoyance, stress symptoms and coping strategies. Noise annoyance stress (NASScale) was negatively correlated with the …

Attitudes Of U.S. Wind Turbine Neighbors: Analysis Of A Nationwide Survey, Ben Hoen, Jeremy Firestone, Joseph Rand, Debi Elliot, Gundula Hübner, Johannes Pohl, Ryan Wiser, Multiple Additional Authors

Regional Research Institute for Human Services

Experts predict continuing deployment of wind turbines in the United States, which will create more interactions between turbines and surrounding communities. Policymakers can benefit from analyses of existing wind projects that enable them to better understand likely effects on residents around proposed projects. Our analysis of a randomly drawn, representative national survey of 1705 existing U.S. wind project neighbors provides previously unavailable detail about factors influencing the attitudes of these neighbors toward their local wind projects. Overall, we find positive-leaning attitudes, which improve over time as individuals self-select into communities near existing wind projects. Hearing wind turbines leads to less-positive …

In Search Of The Iraqi Other: Iraqi Fiction In Diaspora And The Discursive Reenactment Of Ethno-Religious Identities, Yasmeen S. Hanoosh

World Languages and Literatures Faculty Publications and Presentations

In Iraqi fiction, the prerogative to narrate the experience of marginal identities, particularly ethno-religious ones, appeared only in the post-occupation era. Traditionally, secular Iraqi discourse struggled to openly address “sectarianism” due to the prevalent notion that sectarian identities are mutually exclusive and oppositional to national identity. It is distinctly in post-2003 Iraq—more precisely, since the sectarian violence of 2006–2007 began to cut across class, civil society, and urban identities—that works which consciously refuse to depict normative Iraqi identities with their mainstream formulations became noticeable. We witness this development first in the Western diaspora, where Iraqi novels exhibit a fascination with …

A Cost-Benefit Analysis Of Livelihood, Environmental And Health Benefits Of A Large Scale, Christina K. Barstow, Randall Bluffstone, Kyle Silon, Karl Linden, Evan Thomas

Economics Faculty Publications and Presentations

Public health interventions targeting contaminated drinking water and indoor air pollution may help to reduce two of the leading causes of death among children under 5 in Rwanda - diarrhea and pneumonia. These interventions also have the potential to provide economic benefits, including reduction in expenditures on fuelwood and time spent on fuelwood collection, environmental benefits through reductions in deforestation and greenhouse gas emissions, and additional economic benefits attributable to health impacts. We evaluate one such large scale intervention, the Tubeho Neza program in Western Rwanda using a cost-benefit analysis. This paper estimates monetized program benefits related to fuelwood savings, …

Estimating The Present Value Of Carbon Sequestration In U.S. Forests, 2015–2050, For Evaluating Federal Climate Change Mitigation Policies, Robert T. Haight, Randall Bluffstone, Jeffrey D. Kline, John D. Coulston, David N. Wear, Kate Zook

Economics Faculty Publications and Presentations

We demonstrate an application evaluating carbon sequestration benefits from federal policy alternatives. Using detailed forest inventory data, we projected carbon sequestration outcomes in the coterminous 48 states for a baseline scenario and three policy scenarios through 2050. Alternatives included (1) reducing deforestation from development, (2) afforestation in the eastern United States and reforestation in the western United States, and (3) reducing stand-replacing wildfires. We used social cost of carbon estimates to evaluate the present value of carbon sequestration benefits gained with each policy. Results suggest that afforestation and reforestation would provide the greatest marginal increase in carbon benefit, far exceeding …

Background: Individuals with post-traumatic stress disorder (PTSD) have a heightened sensitivity to subsequent stressors, addictive drugs, and symptom recurrence, a form of behavioral sensitization. N-methyl-D-aspartate receptors (NMDARs) are involved in the establishment and activation of sensitized behavior.

Objective: We describe a protocol of a randomized placebo-controlled Phase 1b proof-of-mechanism trial to examine target engagement, safety, tolerability, and possible efficacy of the NMDAR antagonist lanicemine in individuals with symptoms of PTSD (Clinician Administered PTSD Scale [CAPS-5] score ≥ 25) and evidence of behavioral sensitization measured as enhanced anxiety-potentiated startle (APS; T-score ≥ 2.8).

Methods: Subjects (n = 24; age range 21–65) …

The Small Publisher’S Guide To Audiobooks, Stephanie Anderson

Book Publishing Final Research Papers

While audiobooks have been around since the invention of the phonograph, the invention of streaming technologies, combined with our increasingly fast-paced, multitasking culture, has caused audiobooks to become the fastest growing market in the publishing industry in recent years. In fact, since 2013 the audiobooks market has seen sales growth of an average of 20% per year, according to studies done by the Audio Publishers Association. However, many small publishers are not entering into the vital “new” frontier and reaching greater markets because of assumptions about the cost-prohibitive nature of creating audiobooks, and a lack of knowledge of the industry …

Consumerism-Driven History: The American Girl Brand As Publisher And Arbiter Of Girlhood Identity, Sarah Loepp

Book Publishing Final Research Papers

American Girl is a highly recognizable brand that wears several hats: publisher, dollmaker, and purported educator. Yet many researchers point out a disconnect between merchandise-driven aspects of the company and its educational qualities, as well as the set of cultural values suggested in material consumption versus the brand literature’s stated representation of girlhood. This paper outlines research pertaining to these issues before engaging in a close reading analysis of one of the historical character’s book series, ascertaining how the aforementioned concepts play out in the text itself. Assessment of American Girl consumption practices further draw from the brand’s website and …

Resting-State Functional Connectivity Of The Habenula In Mood Disorder Patients With And Without Suicide-Related Behaviors, Elisa Ambrosi, David B Arciniegas, Kaylah N Curtis, Michelle A Patriquin, Gianfranco Spalletta, Gabriele Sani, B Christopher Frueh, J Christopher Fowler, Alok Madan, Ramiro Salas

Staff and Researcher Publications

The habenula is a small midbrain structure that is important for brain signaling and learning from negative events. Thus, the habenula is strongly connected to both the reward system and motor regions. Increasing evidence suggests a role for the habenula in the etiology of psychiatric disorders, including mood and substance use disorders. However, no studies to date have investigated habenular resting-state functional connectivity (rsFC) in suicide-related behaviors (SB). The authors enrolled 123 individuals with major depressive disorder (MDD) or bipolar disorder and a history of suicide-related behaviors (SB+), 74 individuals with MDD or bipolar disorder and a history of suicidal …
