Can Hematocrit Levels At Estrus In Dairy Cows And Sheep Be An Indicator For Pregnancy Success?, Khaled Elaraby Kelany

Animal Sciences

Despite the major reproductive advances in the livestock industry, prenatal embryonic loss is still one of the major issues that causes substantial economic loss. While there are many tests available to determine pregnancy soon after maternal recognition of pregnancy, most of the prenatal losses are undetectable because it occurs before then. Based on previous research we hypothesized that increased plasma volume around the time of estrus will increase the survivability of the embryo at early stages of gestation. However, our findings indicate that hematocrit levels are not a consistent measurement in determining successful pregnancies.

Teaching Race, Racism, And Racial Justice: Pedagogical Principles And Classroom Strategies For Course Instructors, M. Brielle Harbin, Amie Thurber, Joe Bandy

School of Social Work Faculty Publications and Presentations

Teaching on topics of race and racism presents unique challenges to leaders in the university classroom setting. Despite an increasing number of instructors bringing a critical analysis of racial in/justice to their curriculum, many report challenges in teaching this content effectively. In this article, we address these challenges. We define common challenges in teaching racial content and articulate four principles for course planning around topics of race, racism, and racial justice. Then, drawing on a systematic review of scholarship examining issues of difference within a diverse range of disciplinary settings, we introduce a set of five pedagogical strategies, and supporting …

Topics discussed include without sufficient attention to history, to current circumstance, to all the points of intersection that we do not yet see, any single course of action reflects a limited and incomplete narrative; and mentions it is easier to think that there are victims and perpetrators than to admit that some among us are both.

Nature-Based Designs To Mitigate Urban Heat: The Efficacy Of Green Infrastructure Treatments In Portland, Oregon, Yasuyo Makido, Dana E. Hellman, Vivek Shandas

Urban Studies and Planning Faculty Publications and Presentations

Urban heat is a growing environmental concern in cities around the world. The urban heat island effect, combined with warming effects of climate change, is likely to cause an increase in the frequency and intensity of extreme heat events. Alterations to the physical, built environment are a viable option for mitigating urban heat, yet few studies provide systematic guidance to practitioners for adapting diverse land uses. In this study, we examine the use of green infrastructure treatments to evaluate changes in ambient temperatures across diverse land uses in the city of Portland, Oregon. We apply ENVI-met® microclimate modeling at the …

High School Completion In Context: Student- And School-Level Factors Related To On-Time Graduation, Mathew C. Uretsky

School of Social Work Faculty Publications and Presentations

Background/Context: There is an expansive body of research concerning high school graduation; however, most studies omit students who persist through four years of high school without earning a diploma. In addition, there is scant research exploring longer-term outcomes among students whose academic trajectories do not fit within the traditional four-year model of high school graduation, including eventual graduation, post-secondary enrollment, or engagement in the workforce.

Purpose/Objective/Research Question/Focus of Study: The current study addresses the substantive gaps in research regarding high school non-completion by examining the college and workforce outcomes of persisters—defined here as students who do not formally …

Quality Of Life And Stigma Among People Living With Hiv/Aids In Iran, Mohammad Ebrahimi Kalan, Jian Han, Ziyad Ben Taleb, Kristopher P. Fennie, Mohammad Asghari Jafarabadi, Maryam Dastoorpoor, Nima Hajhashemi, Mitra Naseh, Shahnaz Rimaz

School of Social Work Faculty Publications and Presentations

Background: Stigma against HIV profoundly affects the quality of life (QOL) of people living with HIV/AIDS (PLWHA). We aimed to assess the factors associated with QOL in PLWHA in Iran, specifically HIV-related stigma, sociodemographic and clinical characteristics.

Methods: Two hundred PLWHA participated in this cross-sectional study. Data were collected using sociodemographic, stigma, and WHO-QOL-BREF questionnaires. Correlations, ANOVAs, and Student’s t-distribution tests were performed as bivariate analyses. We employed stepwise multiple linear regression analysis to explore the main factors associated with QOL domains.

Results: Six domains of QOL were negatively correlated with three domains of stigma (p < 0.001 for all). Stepwise multiple linear regression revealed that, after adjusting for con-founders, lack of healthcare insurance, having no basic knowledge of HIV/AIDs prior to diagnosis, low monthly income of participants and family, and stigma (blaming and distancing, discrimination, and fear) were associated with low mean score of different domains of QOL.

Investigating Metrical Context Effects On Anticipatory Coarticulation In Connected Speech Development, Jillian Adkins, Christina Gildersleeve-Neumann, Melissa A. Redford

Speech and Hearing Sciences Faculty Publications and Presentations

If rhythm acquisition is influenced by the development of articulatory timing, then metrical structure might be expected to condition this timing. This study tested this hypothesis by investigating anticipatory effects of an upcoming noun on the production of a preceding determiner, under the assumption that anticipatory coarticulation indexes chunking. Simple S-V-O sentences were elicited from 5-year-olds, 8-year-olds, and adults. The V was either monosyllabic packed or disyllabic patted. The O was a determiner phrase where nouns varied either in onset place-of-articulation (POA; tack vs. cat) or in their rhymes (tack vs. toot). Acoustic analyses of determiner schwa F1 and F2 …

Social Norms, Misperceptions, And Mosquito Net Use: A Population‑Based, Cross‑Sectional Study In Rural Uganda, Jessica M. Perkins, Paul J. Krezanoski, Sae Takada, Bernard Kakuhikire, Vincent Batwala, Alexander Tsai, Nicholas A. Christakis, David R. Bangsberg

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Mosquito net use is an essential part of malaria prevention. Although previous research has shown that many people sleep under a mosquito net in endemic areas, it is unknown whether people underestimate how common it is to sleep under a net every night. Furthermore, perceived social norms about whether most others sleep under a mosquito net every night may contribute to personally sleeping under a net, given decades of research showing that people often mimic others’ behaviours.

Methods: Population-based data were collected from 1669 adults across eight villages in one rural parish in southwestern Uganda. Individuals’ perception about whether …

Exploring The Extent Of The Hikikomori Phenomenon On Twitter: Mixed Methods Study Of Western Language Tweets, Pereira-Sanchez, Miguel Angel Alvarez-Mon, Angel Asunsolo Del Barco, Melchor Alvarez-Mon, Alan R. Teo

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 …

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 …

Supporting Clinical Practice Through Rehearsals, Lubna Javeed

Northwest Journal of Teacher Education

Rehearsing is a form of pedagogy in teacher education to prepare pre-service teachers with instructional practices before live enactments in a classroom. This qualitative study used grounded theory to explore how rehearsals impacted five elementary literacy courses in a university teacher education program. Data comprised of prolonged observations, video recordings of rehearsals, and surveys. The process of coding and re-coding resulted in findings that reflect rehearsing provided Teacher Candidates with confidence with lesson presentation, improved understanding of literacy content, and understand how to make in-the-moment instructional decisions.

Synchronous gastric and colon cancer although reported from East Asia (China, Japan, Korea) remain rare in other parts of the world. We present the case of a 50-year-old lady who presented to the Hialeah Hospital, USA with an eight-month history of generalized abdominal pain and upon investigation was found to have dual gastric and colonic malignancy. While the incidence of gastric cancer has dropped drastically in the USA, colon cancer remains the third most frequent cancer in both men and women. An estimated 2%-17% of oncological patients may be affected by multiple primary malignancies and a high degree of clinical …

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, …

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 …

Winter Feeding Beef Cattle: A Review On Bale Grazing In The Northern Great Plains, Jessalyn Juel Bachler

Range Science

Bale grazing is a relatively unexplored winter feeding option for most beef cattle operations in the Northern Great Plains. Recently, several producers have been looking into using a bale grazing system for winter feeding due to the lower labor requirements and possible reduced cost. When bale grazing, it is not only important to ensure that cattle have adequate nutrition and protection from the winter climate, but also to analyze the positive impacts it has on the ranching ecosystem. Many positive environmental and economic changes have been seen from bale grazing including more efficient nutrient cycling, positive soil health impacts, increased …

Electrical and Computer Engineering Faculty Publications and Presentations

We conducted a pilot study to evaluate the accuracy of a custom built non-contact pressure-sensitive device in diagnosing obstructive sleep apnea (OSA) severity as an alternative to in-laboratory polysomnography (PSG) and a Type 3 in-home sleep apnea test (HSAT). Fourteen patients completed PSG sleep studies for one night with simultaneous recording from our load-cell-based sensing device in the bed. Subjects subsequently installed pressure sensors in their bed at home and recorded signals for up to four nights. Machine learning models were optimized to classify sleep apnea severity using a standardized American Academy of Sleep Medicine (AASM) scoring of the gold …

Schools As Training Grounds For Harassment, Ann C. Mcginley

Scholarly Works

This article deals with the schools’ role in permitting and encouraging peer sex- and gender-based harassment of children and the law’s role in failing to hold schools accountable for their negligent and intentional behavior in sanctioning it. Part I discusses the evidence of rampant sex- and gender-based harassment in schools. Part II analyzes the problem through the lens of masculinities theory and explains how cultural notions of masculinity create incentives for boys (and some girls) to engage in peer sex- and gender-based harassment.

Part III analyzes court cases and OCR decisions and explains the serious disconnect between the two; it …

Judicial Ethics: A New Paradigm For A New Era, Charles G. Geyh

Articles by Maurer Faculty

As the preamble to the Model Code of Judicial Conduct indicates, traditional notions of judicial ethics operate within a rule of law paradigm, which posits that the "three I's" of judicial ethics-independence, impartiality, and integrity-enable judges to uphold the law. In recent decades, however, social science, public opinion, and political commentary suggest that appointed judges abuse their independence by disregarding the law and issuing rulings in accord with their biases and other extralegal impulses, while elected judges disregard the law and issue rulings popular with voters, all of which calls the future of the three I's and judicial ethics itself …

Racism As Self-Love, Grant J. Silva

Philosophy Faculty Research and Publications

In the United States today, much interpersonal racism is driven by corrupt forms of self-preservation. Drawing from Jean-Jacques Rousseau, I refer to this as self-love racism. The byproduct of socially-induced racial anxieties and perceived threats to one’s physical or social wellbeing, self-love racism is the protective at­tachment to the racialized dimensions of one’s social status, wealth, privilege, and/or identity. Examples include police officer related shootings of unarmed Black Americans, anti-immigrant sentiment, and the resurgence of unabashed white supremacy. This form of racism is defined less by the introduction of racism into the world and more on the perpetuation of racially …

Self-Control And Moral Security, Jeanette Kennett, Jessica Wolfendale

Philosophy Faculty Research and Publications

Self-control is integral to successful human agency. But the capacity for self-control requires external support. This paper explores the connections between social conditions, self-control, agency, and the self. Part one offers a taxonomy of self-control. Part two examines the external conditions that support successful agency and self-control, and argues that moral security is a critical foundation for agency. Moral security refers to the degree to which an agent believes that her welfare and her projects are valued by others and by her society. Parts three and four explore how narratives about racism and poverty undermine moral security, and limit and …

Building New Twenty-First Century Medical School Libraries From The Ground Up: Challenges, Experiences, And Lessons Learned., Nadine Dexter, Joanne M. Muellenbach, Elizabeth R Lorbeer, Debra Rand, Matthew E Wilcox, Bradley A Long

Jay Sexter Library Publications and Research

The twenty-first century library at a newly opened medical school often differs from those at traditional medical schools. One obvious difference is that the new medical school library tends to be a born-digital library, meaning that the library collection is almost exclusively digital. However, the unique issues related to building a library at a new medical school are not limited to online collections. A unique start-up culture is prevalent, of which newly appointed directors and other library and medical school leaders need to be aware. This special paper provides an overview of best practices experienced in building new medical school …
