Supply, Demand, And Fiscal Sustainability Of Outdoor Recreation In Utah, Jordan W. Smith, Chris Monz

Environment and Society Faculty Publications

Because Utah's outdoor recreation destinations are managed by several different federal and state agencies, there is no comprehensive and consistent information on the amount and types of outdoor recreation resources available within the state. Additionally, there has been no research to date on how state programs whose revenues are dependent on outdoor recreation activity, are likely to fare in the coming years. This report begins to address these limitations by: 1) compiling and synthesizing data that characterize the amount and location of outdoor recreation resources throughout the state; and 2) presenting the results of a suite of econometric forecasting models …

Subcellular Pathways Through Vglut3-Expressing Mouse Amacrine Cells Provide Locally Tuned Object-Motion-Selective Signals In The Retina, Karl Friedrichsen, Jen-Chun Hsiang, Chin-I Lin, Liam Mccoy, Katia Valkova, Daniel Kerschensteiner, Josh L Morgan

2020-Current year OA Pubs

VGluT3-expressing mouse retinal amacrine cells (VG3s) respond to small-object motion and connect to multiple types of bipolar cells (inputs) and retinal ganglion cells (RGCs, outputs). Because these input and output connections are intermixed on the same dendrites, making sense of VG3 circuitry requires comparing the distribution of synapses across their arbors to the subcellular flow of signals. Here, we combine subcellular calcium imaging and electron microscopic connectomic reconstruction to analyze how VG3s integrate and transmit visual information. VG3s receive inputs from all nearby bipolar cell types but exhibit a strong preference for the fast type 3a bipolar cells. By comparing …

Cognitive And Economic Development, John Luke Gallup

OHSU-PSU School of Public Health Annual Conference

A burgeoning literature finds that early childhood risk factors have large causal effects on individuals' cognitive development, education and earnings, but has not assessed the impact on the economy as a whole.

Cognitive ability is the foundation of human capital and the capacity to learn. The risk factors for poor cognitive development are very high in many countries. Each risk factor also causes child mortality, making child survival a viable proxy for good cognitive development conditions. The cognitive development of current workers happened decades earlier when they were children, providing a predetermined correlate. Controlling for country characteristics, income levels and …

Knowledge Of Medicaid Expansion To Recent And Undocumented Immigrants Among Oregon Mexican-Origin Latinos: (Work In Progress), Nancy Ledezma, Grace Parra, Alejandra Nunez, Dr. Blair Darney

OHSU-PSU School of Public Health Annual Conference

Background

Recent and undocumented immigrants are explicitly excluded from federal Medicaid and state insurance exchanges. The first phase of Healthier Oregon was implemented in July 2022 and expanded Medicaid (OHP) benefits to undocumented immigrants ages 19-25 or 55 and older. The second phase was implemented in July 2023 and extended benefits to everyone regardless of age. We assessed understanding of Healthier Oregon among Mexican-origin Latinos. We hypothesize that many potentially eligible people may not know about the program, if they qualify, or how to apply.

Methods

This is a cross-sectional study in collaboration with the General Consulate of Mexico. Our …

Understanding Variation In Provider Referral Rates To Early Intervention For Children With Developmental Delays, Gabriella Tangkilisan, Zoe Kilmer, Michelle Owens, Benjamin Sanders, Katharine Zuckerman

OHSU-PSU School of Public Health Annual Conference

Background:

Early detection and treatment of developmental disabilities (DD), including Autism Spectrum Disorder (ASD), improves language, IQ, and adaptive outcomes. Guidelines recommend immediate referral to Early Intervention (public developmental therapy services) upon positive ASD/DD screening in infant/toddler well child checks. However, children screening positive for ASD/DD are not always referred for Early Intervention services. This project aimed to understand why pediatricians do and do not refer children with positive DD/ASD screens to early intervention.

Methods:

We conducted qualitative interviews with pediatricians who participated in a randomized trial investigating family navigation for children with autism risk. We determined pediatrician referral rates …

A Window Of Opportunity: Describing Participants Engaged In A Comprehensive Perinatal Care Model To Treat Substance Use Disorder During Pregnancy, Christina Jäderholm

OHSU-PSU School of Public Health Annual Conference

In 2019, 12% of pregnant persons were estimated to use psychoactive substances, the highest rate in US history. Substance use disorder (SUD) is a chronic, relapsing condition, and while pregnancy presents a unique opportunity for SUD intervention, research on pregnant and postpartum SUD patient experiences is vital for informing perinatal systems of care. The purpose of this presentation is to describe a sample from SUN, a comprehensive perinatal care program for pregnant persons with SUD in North Carolina.

Methods

We abstracted medical records (n=29), surveyed participants (n=29), and conducted two focus groups (n=7). Medical records provided participant demographics; medical, social, …

Simply Snake Sprites And Sounds: Snake Detection Theory In Video Games, Entropy Cramer

Scholars Week

Snake Detection Theory states that there is an innate evolutionary advantage to respond to snake stimuli stronger and faster than non-snake stimuli. This theory has been supported by studies measuring brain activity in infants looking at images of snakes (Bertels et al., 2020), reactions in wild monkeys and marmosets (Wombolt & Caine, 2016; Isbell & Etings, 2017; Van Strien et al, 2016; Dinh et al., 2021), and in peripheral attention tasks in adults (Kawai & He, 2016; Kawai & Qui, 2020; Gallup & Meyers, 2021). Also, over 53% of UK citizens report anxiety around snakes, and it is one of …

Exploring Decolonial And Indigenous Mental Health Framework And Practice To Address Complex Trauma Among Palestinian Youth Living Under Violence Of Settler-Colonialism, Vivian L. Duong, Corrin Murphy

OHSU-PSU School of Public Health Annual Conference

The growing settler colonial project of Israel forced indigenous Palestinians to flee from their homeland to further the Zionist movement of establishing a Jewish-majority state. The forced dispossession and displacement of Palestinians at this time was referred to as the Nakba, or catastrophe (Masalha, 2002). From 1947 and 1949, approximately 750,000 Palestinians from a population of 1.9 million were made refugees (Al Jazeera, 2017). Also referred to as the ethnic cleansing of Palestine, Zionists forcibly took over 78 percent of Palestine, destroyed about 530 villages and cities, and killed around 15,000 Palestinians including more than 70 massacres (Al Jazeera, 2017). …

Supporting Self-Managed Abortion Care In “Practice Not Premise”: Provider Perspectives, Roles, And Referral Pathways In India, Laura E. Jacobson Mph, Caila Brander, P. Balasubramanian, Sruthi Chandrasekaran, Blair Darney, Julia Goodman, Ruvani Jayaweera, Caitlin Gerdts

OHSU-PSU School of Public Health Annual Conference

Objective: Describe provider perspectives and roles in self-managed abortion (SMA) in India and identify referral pathways to facility- and self-managed abortion care.

Methods: We conducted a qualitative study of 33 semi-structured interviews with a range of providers (medical, community health, and pharmacy) in India. We conducted a thematic analysis and identified referral pathways including the type of provider, the abortion care modality (in-facility or SMA), and the reason.

Results: Referrals to facility-managed abortion care were common. Providers' perception of SMA safety coupled with­ liability concerns resulted in discouraging clients from seeking SMA. Nonetheless, participants acknowledged three areas where providers played …

Impact Of Two Shift Schedules On Post-Shift Blood Pressure In Firefighters, Ayeisha H. Haswarey

OHSU-PSU School of Public Health Annual Conference

Background: Firefighters have an increased risk of cardiometabolic disease compared to the general population. Blunted blood pressure (BP) dipping during nocturnal sleep is associated with increased cardiometabolic disease morbidity/mortality. Shift work can alter diurnal BP oscillation, but the extent of alteration by different schedules remains debated. No study to date has examined firefighting shift schedules, necessitating a longitudinal evaluation to begin to understand their implications for cardiometabolic health. Thus, this preliminary analysis compares how two common schedules (24/48 hours on/off vs. 1/3/2/3 days on/off) impact post-shift BP and dipping in 20 firefighters.

Methods: 20 participants (10% female; 25-54 years of …

Inequities In Chronic Stress Exposure At The Intersection Of Race, Gender, And Sexual Identity In A Nationally Representative Sample Of U.S. Adults, Jordan M. Lancaster, Efrain H. Chavez Martinez

OHSU-PSU School of Public Health Annual Conference

Background

Social inequity rooted in systemic oppression is robustly associated with mental and physical health; chronic stress is highlighted as a key mechanism. Limited research examining the association between sexual identity alone and C-reactive protein (CRP) – an upstream biological marker of chronic stress exposure – has yielded mixed results.

Purpose

To examine whether race/ethnicity, gender, and sexual identity interact to produce unequal levels of CRP.

Methods

Using cross-sectional data from the 2003-2010 waves of the National Health and Nutrition Examination Survey, we examined intersectional (self-reported race*gender*sexual identity) patterns in log-transformed CRP levels using a multivariable linear model among 10,885 …

3. Recruiting TGNB providers and …

Gender Affirming Surgery And Pain In Adolescents: Teen And Parent Experiences, Corrin Murphy, Eleanor Battison, University Of Rhode Island, Anna Wilson Phd

OHSU-PSU School of Public Health Annual Conference

Background: Adolescents seeking gender affirming medical care face unique biopsychosocial challenges, including experiences of discrimination and stigma. Transgender and gender diverse (TGD) adolescents often undergo gender affirming surgery (GAS). While there is an increase in GAS for TGD adolescents in the U.S., little is known about the pain experiences in the post-surgical period among these youth. There have been no studies to our knowledge that examine the psychological functioning of parents and their ability to handle their child's distress, which may be affected by their child's post-GAS pain experiences. Parental responses to their children’s pain and distress may, in turn, …

The Cost Of Healthy Eating, Diana Prychyna, Miriam R. Elman, Joy Kim, Karen F. Miller, Deonni P. Stolldorf, Sean P. Collins, Bory Kea

OHSU-PSU School of Public Health Annual Conference

Abstract

Background

Each year in the United States, 15-20% of 1 million visits to the Emergency Department for Acute Heart Failure result in home discharge, with patients often experiencing adverse health outcomes within 30 days. The study, Get With the Guidelines in Emergency Department Patients With Heart Failure (GUIDED-HF), utilized ‘Self-Care Coaches’ who meet participants via telehealth calls to discuss self-care maintenance after discharge as a strategy to mitigate adverse health outcomes; and offer provisions of resources, including a cookbook by the American Association for Heart Failure Nurses (AAHFN).

The Association Between Acculturation & C-Reactive Protein In U.S. Immigrants: A Cross-Sectional Study, Jessica Kilinski Bs, Rosol Mikail Bs, Kelly M. Reavis Phd, Mph, Deborah Karasek Phd, Mph

OHSU-PSU School of Public Health Annual Conference

Purpose: Immigrants undergo acculturation as they assimilate to a different culture, potentially leading to immense stress. Our objective was to examine the association between acculturation and C-reactive protein (CRP), a marker of stress-induced inflammation. We hypothesized that U.S. foreign-born adults 20 years and older with higher degrees of acculturation would have higher CRP levels compared to those with lower acculturation.

Method: We used 2017-2018 National Health and Nutrition Examination Survey (NHANES) data from 1526 participants to conduct a cross-sectional analysis. We measured acculturation as language spoken at home (categorized as low, moderate, and high) and examined its association with CRP …

Gaza's Healthcare System In Collapse: An Exploratory Analysis Of Healthcare Attacks In Occupied Palestinian Territories (Opts) And Israel Since October 2023, Vincenzo J. Cornacchione

OHSU-PSU School of Public Health Annual Conference

Decades of apartheid practices and oppression in Occupied Palestinian Territories (OPTs), marked by mass displacement, restricted access to essential services, and countless human rights violations, have culminated in today's systematic dismantling of Gaza’s healthcare infrastructure. To investigate the systematic obstruction of healthcare access in OPT, this exploratory analysis employs an open intelligence dataset containing event data on reported healthcare attack incidents in OPT and Israel since October 2023. Specifically, this analysis seeks to elucidate the nature and extent of healthcare attacks in OPT by answering student-defined research questions, based on a priori expectations around the data. The analysis confirms that …

基于二分算法构建的非参数 Cd-Cat 选题策略及终止规则, 李 俊杰, 郑 慧婧

Chinese/English Journal of Educational Measurement and Evaluation | 教育测量与评估双语期刊

CD-CAT 能对学生进行诊断和评估，对提升教学效果具有重大意义。但在课堂教学情景中，无法像大规模测评可以使用大量样本对项目参数进行准确估计，此时非参数 CD-CAT 成为唯一可行的选择。相比于参数 CD-CAT，非参数 CD-CAT 起步较晚，且非参数CD-CAT的研究主要集中在选题策略方面，但已有的非参数选题策略存在效率不高的缺点，且非参数终止规则则是鲜有研究。因此本研究提出了两种更高效的选题策略:非参数动态二分选题策略（NDBS）和一般非参数动态二分选题策略（GNDBS），以及一种非参数二分终止规则(NDBI)。模拟研究结果表明：（1）所有条件下，NDBS的模式判准率均高于NPS，因此，在完全没有样本时，可选用NDBS作为选题策略。（2）在大多数情况下，GNDBS的性能优于其他选题策略，因此，在具有少量样本时，可选用GNDBS作为选题策略。（3）在变长测验中，当研究目的是获得更准确的分类结果时，可以降低NDBI规则的临界值；相反，可以适当提高NDBI和GNDBI规则的临界值。

Non-Parametric Cd-Cat Item Selection Strategy And Termination Rules Based On Binary Search Algorithm, Junjie Li, Huijing Zheng

Chinese/English Journal of Educational Measurement and Evaluation | 教育测量与评估双语期刊

CD-CAT plays a significant role in diagnosing and assessing students, contributing significantly to improving teaching effectiveness. However, in classroom teaching scenarios, unlike large-scale assessments where a large number of samples can be used to accurately estimate item parameters, non-parametric CD-CAT becomes the only feasible choice. Compared to parametric CD-CAT, non-parametric CD-CAT started later, and research mainly focuses on non-parametric item selection strategies. However, the existing non-parametric item selection strategies have the disadvantage of low efficiency, and there is little research on non-parametric termination rules. Therefore, this study proposes two more efficient item selection strategies: Non-Parametric Dynamic Binary Search (NDBS) and …

Developmental Programming Of Normal Versus Metabolically Altered Pancreas In Rat: Effect Of Gestational Diabetes, Sanabil Ali Ahmed

Thesis/ Dissertation Defenses

Diabetes Mellitus (DM) is a chronic condition characterised by pancreatic β-cell dysfunction and consistent elevated blood glucose levels (hyperglycaemia), either due to the inability of the body to produce any or adequate amounts of insulin or the inability of the body to effectively utilise the produced insulin (i.e., insulin resistance). DM can be classified into 3 main types: Type 1 DM (T1DM), Type 2 DM (T2DM), and Gestational Diabetes Mellitus (GDM). GDM is defined as “hyperglycaemia that is first diagnosed during pregnancy with glucose levels below those considered diagnostic of overt diabetes outside of pregnancy”. The mature pancreas is a …
