The Consequences Of Predators Without Prey, Mitchell A. Parsons, Thomas M. Newsome, Julie K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

Rapid and ongoing environmental change is leading to scenarios where marine and terrestrial predators are persisting without prey, either by scavenging or using anthropogenic foods. Despite investigations into the effects of predator presence or absence on prey behavior and ecology, little research has assessed the effect of prey absence on predators. Here, we synthesize research on scavenging and the use of anthropogenic resources by marine and terrestrial predators; hypothesize how the use of these resources may change predator behavior with respect to their social structure, space use, life history, and individual behavioral traits; and illustrate how these changes are likely …

Improving Evaluation Of Nonlethal Tools For Carnivore Management And Conservation: Evaluating Fladry To Protect An Endangered Species From A Generalist Mesocarnivore, R. M. Windell, L. L. Bailey, J. K. Young, T. M. Livieri, D. A. Eads, S. W. Breck

United States Department of Agriculture Wildlife Services: Staff Publications

Carnivore conservation and management are global research priorities focused on reversing population declines of imperiled species and identifying more effective and humane management of generalist carnivores with thriving populations. Nonlethal methods to mitigate conflict are increasingly used to advance conservation objectives; however, there is limited knowledge about the effectiveness of many nonlethal methods. We tested a nonlethal tool (fladry), that serves as a barrier to deter wolves Canis lupus and coyotes Canis latrans, for its efficacy at preventing coyotes from using prairie dog Cynomys ludovicianus colonies, the primary prey for critically endangered black-footed ferrets Mustela nigripes. We used …

Social Media As A Window Into Human-Wildlife Interactions And Zoonotic Disease Risk: An Examination Of Wild Pig Hunting Videos On Youtube, Hailey E. Mclean, Lauren M. Jaebker, Aaron M. Anderson, Tara L. Teel, Alan D. Bright, Stephanie A. Shwiff, Keith M. Carlisle

United States Department of Agriculture Wildlife Services: Staff Publications

Wild pigs (Sus scrofa) damage agriculture and the environment, as well as transmit diseases to animals and people. Hunters are particularly vulnerable to zoonotic disease risks when harvesting wild pigs. Management agencies have endeavored to inform the public about disease risks associated with wild pigs and best practices for mitigating such risks. However, the extent that this guidance has reached hunters and influenced their practices is unclear. We approached this topic through an analysis of wild pig hunting videos on YouTube. We found evidence of relatively few behaviors and communications regarding disease risks and best practices for personal …

Relative Acceptance Of Brodifacoum Pellets And Soft Bait Sachets By Polynesian Rats (Rattus Exulans) On Wake Atoll, Peter J. Kappes, Shane R. Siers

United States Department of Agriculture Wildlife Services: Staff Publications

Removing invasive rats from island ecosystems using rodenticides has proven conservation benefits and is an important management tool for conserving and restoring island ecosystems. However, rodenticide-based eradications can fail if not all rats consume enough bait to result in lethal toxicosis. A recent post-operational review of a failed attempt to eradicate rats from Wake Atoll suggested that some individuals may not have ingested a lethal dose of rodenticide due to potential dietary and/or sensory preferences developed via regular access to anthropogenic food sources. These food sources may be higher in fats and oils, possessing different sensory properties (e.g., softer, chewier, …

Welfare Performance Of Three Foothold Traps For Capturing North American River Otters Lontra Canadensis, Matthew J. Lovallo, H. B. White, J. D. Erb, M. S. Peek, Thomas J. Deliberto

United States Department of Agriculture Wildlife Services: Staff Publications

Foothold traps are effective tools for the live capture and restraint of wildlife for management and research. Successful river otter Lontra canadensis restoration programs throughout North America used them extensively. Restoration programs used a variety of methods and models of foothold traps, but comprehensive efforts to describe and quantify injuries associated with river otter captures have been limited. We evaluated injuries of river otters caught in three commercially available models of foothold traps including the number 11 double long-spring with standard jaws, the number 11 double long-spring with double jaws, and the number 2 coil-spring trap. Based on examinations of …

Scaup Depredation On Arkansas Baitfish And Sportfish Aquaculture, Stephen A. Clements, Brian S. Dorr, J. Brian Davis, Luke A. Roy, Carole R. Engle, Katie C. Hanson-Dorr, Anita M. Kelly

United States Department of Agriculture Wildlife Services: Staff Publications

Lesser scaup (Aythya affinis) and greater scaup (A. marila), hereafter scaup, consume a variety of aquatic invertebrates, plants, and occasionally small fish. Scaup have foraged on commercial aquaculture farms in the southern United States for decades. However, the types, abundance, and rate of fish exploitation by scaup on baitfish and sportfish farms are not well documented. Thus, information is needed to understand how fish and other foods influence scaup use of aquatic resources, and any potential economic effects of depredation of fish. From November–March in winters 2016–2017 and 2017–2018, we conducted 1,458 pond surveys to estimate …

Impact Of Covid-19 On The Us And Texas Economy: A General Equilibrium Approach, Lirong Liu, Steven S. Shwiff, Stephanie A. Shwiff, Maryfrances Miller

United States Department of Agriculture Wildlife Services: Staff Publications

This paper examines the impact of COVID-19 on the US and Texas economy using a computable general equilibrium model, REMI PI+. We consider three scenarios based on economic forecasts from various sources, including the University of Michigan’s RSQE (Research Seminar in Quantitative Economics), IMF, and the Wi orld Bank. We report a GDP loss of $106 million (a 6% decline) with 1.2 million jobs lost (6.6%) in Texas in 2020. At the national level, GDP loss is $996 billion (a 5% decline) with 11.5 million jobs lost (5.5%) in the same year. By 2026, the aggregate total GDP loss in …

Conflict, Coexistence, Or Both? Cougar Habitat Selection, Prey Composition, And Mortality In A Multiple-Use Landscape, David C. Stoner, Mark A. Ditmer, Dustin L. Mitchell, Julie K. Young, Michael L. Wolfe

United States Department of Agriculture Wildlife Services: Staff Publications

Western North America is experiencing remarkable human population growth and land-use change. Irrigation and associated cultivation have led to colonization of urban-wildland interface (UWI) environments by mule deer (Odocoileus hemionus), and consequently, cougars (Puma concolor). In the wake of these changes, human-wildlife conflicts have increased in tandem with questions about long-term species conservation. To address these concerns, we fit 79 cougars with radio-telemetry collars in the Oquirrh Mountains near Salt Lake City, Utah (2002–2010). Our goal was to evaluate variation in cougar habitat selection, diet, and cause-specific mortality in a landscape dominated by urban, military, and industrial activities. We used …

Other People’S Families: How Social Ties Shape Entrance Into The Medical Profession, Lillian Sims

Theses and Dissertations--Educational Policy Studies and Evaluation

Not enough members of low-income, rural, and minoritized populations are successfully prepared for and recruited into medical school, exacerbating issues of unequal access to healthcare and limiting access to the profession. While a multitude of factors contribute to this problem, early social exposure to others in a field can act as a key contributor to career interest and a key advantage for entering the profession. Meanwhile, students without early social exposure to healthcare may take unconventional paths to medical school or may struggle to fit into the unique culture of medicine when they do enter training, especially if they belong …

RATIONAL:

Increased maternal health literacy (MHL) has contributed considerably to maternal and child health outcomes in many countries. Malnutrition, and low coverage of child vaccination and breastfeeding are major health concerns in Laos, but there is little insight into mothers' literacy on these issues. The aim of this study was to identify the level of MHL of Lao mothers and to explore factors influencing it, in order to provide evidence that can inform policies and planning of health services.

METHODS:

A cross-sectional survey was conducted using a questionnaire on health literacy (ability to access, understand, appraise and apply health-related information) …

Apixaban Discontinuation For Invasive Or Major Surgical Procedures (Adios): A Prospective Cohort Study., Geno J. Merli, Walter K. Kraft, Luis H. Eraso, Taki Galanis, Lynda J. Thomson, Geoffrey O. Ouma, Eugene Viscusi, Jerald Z. Gong, Edwin Lam

Department of Medicine Faculty Papers

Background

Apixaban pharmacokinetic properties and some clinical reports suggest cessation 48 hours prior to surgery is safe, but this has not been demonstrated in a naturalistic setting. We sought to measure the residual apixaban exposure in patients who had apixaban held as part of standard of care peri-operative management.

Methods

This was a prospective, observational study of patients in whom apixaban plasma concentration and anti-Xa activity were measured while at steady state apixaban dosing and again immediately prior to surgery. Clinical management of cessation and resumption of apixaban was at the discretion of the treating physician.

High School Student-Athlete Sleep Habits Using Activity Monitoring, Corey Thomas Ungaro

Graduate Research Theses & Dissertations

Sleep research is an area of scientific inquiry that impacts all individuals due to sleep's effects on health, well-being, and performance. Healthy sleep habits have been shown to improve academic and athletic performance in collegiate student-athletes. Surprisingly, no sleep research has been conducted on high school student-athletes during a semester. High school student-athletes can benefit from understanding their sleep habits and how sleep can affect the development of the adolescent brain and improve performance giving athletes the potential for a competitive advantage. This retrospective analysis aims to examine the sleep habits of student-athletes while balancing their academic and athletic responsibilities …

Routinely Collected Antenatal Data For Longitudinal Prediction Of Preeclampsia In Nulliparous Women: A Population‑Based Study, Anna Sandstrom, Jonathan Snowden, Matteo Bottai, Olof Stephansson, Anna-Karin Wikström

OHSU-PSU School of Public Health Faculty Publications and Presentations

The objective was to evaluate the sequentially updated predictive capacity for preeclampsia during pregnancy, using multivariable longitudinal models including data from antenatal care. This population-based cohort study in the Stockholm-Gotland Counties, Sweden, included 58,899 pregnancies of nulliparous women 2008–2013. Prospectively collected data from each antenatal care visit was used, including maternal characteristics, reproductive and medical history, and repeated measurements of blood pressure, weight, symphysis-fundal height, proteinuria, hemoglobin and blood glucose levels. We used a shared-effects joint longitudinal model including all available information up until a given gestational length (week 24, 28, 32, 34 and 36), to update preeclampsia prediction sequentially. …

When “Tried And True” Advocacy Strategies Backfire: Narrative Messages Can Undermine State Legislator Support For Early Childcare Policies, Liana B. Winett, Jeff Niederdeppe, Yiwei Xu, Sarah Gollust, Erika Franklin Fowler

OHSU-PSU School of Public Health Faculty Publications and Presentations

A core principle of policy advocacy is that to engage decision makers in the urgency, complexity, and controversy of problems, advocates must effectively tell the story of those issues. Policy stories, or narratives, paint mental pictures of what a problem is, who is affected, and how it came to be. Yet, the persuasive effects of narratives on one key group, state legislators, remain understudied. Drawing from the Narrative Policy Framework (NPF), media advocacy, and public interest communications, we sought to inform advocacy strategy by illuminating state legislators’ responses to messages about public investments in quality childcare for all. Contrary to …

Acceptability Of An Intervention To Promote Viral Suppression And Serostatus Disclosure For Men Living With Hiv In South Africa: Qualitative Findings, Mxolisi Mathenjwa, Hazar Khidir, Cecilia Milford, Nzwakie Mosery, Letitia Rambally Greener, Madeline Pratt, Kasey O’Neil, Abigail Harrison, David R. Bangsberg, Steven A. Safren, Jennifer A. Smit, Christina Psaros, Lynn T. Matthews

OHSU-PSU School of Public Health Faculty Publications and Presentations

Men living with HIV ( MLWH ) often have reproductive goals that can increase HIV-transmission risks to their pregnancy partners. We developed a safer conception intervention for MLWH in South Africa employing cognitive behavioral skills to promote serostatus disclosure, ART uptake, and viral suppression. MLWH were recruited from an HIV clinic near Durban, South Africa, and encouraged to include partners in follow-up visits. Exit in-depth interviews were conducted with eleven men and one female partner. The emerging over-arching theme is that safer conception care mitigates internalized and community-level HIV-stigma among MLWH. Additional related sub-themes include: ( 1 ) safer conception …

Impact Of Vaccine Supplies And Delays On Optimal Control Of The Covid-19 Pandemic: Mapping Interventions For The Philippines, Carlo Delfin S. Estadilla, Joshua Uyheng, Elvira P. De Lara-Tuprio, Timothy Robin Y. Teng, Jay Michael R. Macalalag, Ma. Regina Justina E. Estuar

Mathematics Faculty Publications

Background

Around the world, controlling the COVID-19 pandemic requires national coordination of multiple intervention strategies. As vaccinations are globally introduced into the repertoire of available interventions, it is important to consider how changes in the local supply of vaccines, including delays in administration, may be addressed through existing policy levers. This study aims to identify the optimal level of interventions for COVID-19 from 2021 to 2022 in the Philippines, which as a developing country is particularly vulnerable to shifting assumptions around vaccine availability. Furthermore, we explore optimal strategies in scenarios featuring delays in vaccine administration, expansions of vaccine supply, and …

The purpose of this project is to gain an understanding how parents of children with autism are affected by caregiver burnout. We want to understand the different factors that contribute to this burnout and analyze how individuals are affected differently. To do this, we are sending

out a survey using Likert scale items to assess parents’ stress and burnout. We will be carefully selecting statements based off information we gather through peer reviewed journal articles. We would then like the parents to decide how strongly they agree or disagree with each question. This will create a more in-depth picture of …

Neural Stem Cell Metabolic Changes In The Presence Of Interferon-Gamma, Dylan Mckibben

Williams Honors College, Honors Research Projects

Spinal cord injury results in significant disability and health care costs due to an inability of the mature central nervous system to regenerate. One potential therapy would be implantation of neural stem cells to the injury site and stimulation of their differentiation to mature neurons. Previous work has shown that the cytokine interferon-gamma can promote this process; however, the signaling pathways induced in neural stem cells have not been well-defined. This proposal examines neural stem cell metabolic responses to signaling induced by interferon-gamma. Two questions will be answered: i) What specific metabolic pathway is activated to guide neural stem cell …

Maintaining Population Health In Low‐ And Middle‐Income Countries During The Covid‐19 Pandemic: Why We Should Be Investing In Community Health Workers, Benjamin Palafox, Alicia Renedo, Gideon Lasco, Lia M. Palileo-Villanueva, Dina Balabanova, Martin Mckee

Development Studies Faculty Publications

Community health workers in low- and middle-income country primary health care systems are well suited to perform essential functions on the frontlines of Covid-19 pandemic responses. However, clear and coordinated guidance, updated infection control training, and reliable access to personal protective equipment must be ensured in order to deploy them safely and effectively. With these additional responsibilities, community health workers must also be supported to ensure that hard-fought gains in population health, including progress on non-communicable diseases, are sustained throughout the pandemic.

Beyond The Bump: Reconceiving The Philosophy Of Pregnancy, Hazel T. Bianas, Leni Dlr Garcia, Ninotchka Mumtaj B. Albano

Philosophy Department Faculty Publications

French philosopher Hélène Cixous (1976) stressed the importance of feminine writing. She believes that women should take part in sharing their experiences from their own novel points-of-view. We discuss that while pregnancy is an experience unique to women; it has been misappropriated by patriarchal structures throughout the years. The pregnancy bump; which is more than just evidence of the uterus stretching to accommodate the fetus; is a symbol of a woman's triumphs and struggles all throughout conception; pregnancy and childbirth. We show that women have already gone beyond the bump and challenged existing patriarchal systems through different means; as Cixous …
