A Survey Of Sampling Methods For Hyperspectral Remote Sensing: Addressing Bias Induced By Random Sampling, Kevin T. Decker, Brett J. Borghetti

Faculty Publications

Identified as early as 2000, the challenges involved in developing and assessing remote sensing models with small datasets remain, with one key issue persisting: the misuse of random sampling to generate training and testing data. This practice often introduces a high degree of correlation between the sets, leading to an overestimation of model generalizability. Despite the early recognition of this problem, few researchers have investigated its nuances or developed effective sampling techniques to address it. Our survey highlights that mitigation strategies to reduce this bias remain underutilized in practice, distorting the interpretation and comparison of results across the field. In …

Measuring The Paris Agreement’S Impact On Wind Energy Usage In Member Countries, Jadyn Lucey

Global Tides

This review examines the impact of the Paris Agreement's implementation on the development of wind energy across three regions, the European Union (EU), Brazil, and Saudi Arabia. These selected regions respectively represent developed, developing, and OPEC member countries. The Paris Agreement aimed to limit the global warming temperature 1.5 C by 2030, encouraging actors to transition their energy into cleaner, renewable sources. Wind energy thus emerged as a tool in the decarbonization efforts of the agreement. This review compares wind energy growth before and after the Paris Agreement's establishment, through analyzing each region's strategies in response to their differing economic …

La Puissance Douce Française Manifestée Par Les Politiques Linguistiques En Afrique, Barbara O. Olewska

Global Tides

Du premier étape des colonisateurs français sur la terre africaine jusqu’à le français étant l’une des langues primaires en Afrique, les français avait eu une influence en Afrique. Pour comprendre comment les politiques linguistiques agissent comme une passerelle de l'implémentation de la puissance douce française en Afrique, nous explorons les politiques linguistiques et systèmes d’éducation en Côte d’Ivoire, au Sénégal, et au Burkina Faso. La littérature décrit comment le français est la langue d'administration dans ces trois pays, donc il est valorisé sur les langues locales. La présence intense du français permet à la France d’employer la puissance douce en …

After The Economic Downfall At The Coastal Frontier: A Portrait Of Women Persisting Amidst Sea Abrasion In Northern Bekasi, Muhammad R. A. Ghifari, Gilang Mahadika

Antropologi Indonesia

This article explores the socio-environmental transformations in Muara Gembong, a coastal frontier in northern Bekasi, Indonesia, that once thrived as a hub for shrimp and milkfish farming but is now grappling with environmental degradation and economic decline. By drawing on feminist political ecology (FPE), the study examines how women in the region have adapted to the deteriorating environment, driven by coastal erosion, mangrove loss, and the collapse of fish pond businesses. While men traditionally dominated the local economy as aquaculturists, women have assumed critical roles in sustaining household livelihoods through creative economic activities, such as weaving wlingi laut (Cyperus malaccensis) …

Academyhealth - 2024 Data Visualization Winners, Chelsea Keating, Emily Boniface, Mina Colon

OHSU-PSU School of Public Health Annual Conference

Social determinants of health, such as income, employment, social contexts, and the built environment, influence the risk of food insecurity. Food insecurity can be defined as uncertain access to food and can lead to negative health outcomes like increased risk for obesity, chronic disease, and adverse effects on a child's development and mental health. Drivers like limited physical access to food, limited transportation options, and the quality and access to food assistance programs within local systems perpetuate health disparities—particularly in those communities with populations who have been systematically marginalized. This descriptive study uses 2022 data from the National Health Interview …

Exploring Health Equity With Culturally Specific Providers Of Permanent Supportive Housing, Judith R. Solomon

OHSU-PSU School of Public Health Annual Conference

Chronic homelessness is an important public health issue. Permanent Supportive Housing (PSH) is a promising opportunity for transitioning people experiencing homelessness into housing, however there remain unaddressed racial inequities in service provision and outcomes. The aim of this study is to better understand the role of culturally specific (CS) providers of PSH in improving health equity. I analyzed interviews with CS PSH providers for themes related to health and healthcare. Providers spoke about the importance of connecting clients to healthcare.

Comparing Acuity Of Patient Care At Student Run Free Medical Clinic Locations, Hana Warmflash, Olivia Krol, Alex Foster

OHSU-PSU School of Public Health Annual Conference

Intro:

Student run free medical clinics (SRFC) are present at roughly 75% of Association of American Medical Colleges member institutions1,2 providing care for underserved populations, such as those experiencing houselessness. 3 Persons experiencing houselessness have a higher burden of illness than housed persons but experience a greater barrier to obtaining care4. Delays in care result in more complex and longer hospitals stays4,5.

Our SRFC, Bridges Collaborative Care Clinic (BCCC), functions to address emergent complaints and monitor chronic health conditions. We aim to demonstrate how relocating from River District Navigation Center (RDNC) to a more accessible location, Resource Center (RC), enabled …

How To Kill A Human: Creating An Immersive Learning Game, Théo Caldwell, Nathan Bonnell

OHSU-PSU School of Public Health Annual Conference

How to Kill a Human is an experiment in teaching through gameplay. The environmental crisis facing the planet, though denied by many, is a collection of well-documented historical environmental catastrophes. The purpose of this project was to design a method of relating the impacts of environmental systems on human health, highlighting the dangers of ill planned human tampering, by presenting hypothetical environmental catastrophes and then relating them to documented historical disasters. In pursuit of this goal, we designed a semi-collaborative game for three to six players with a suggested age rating of 10+, ideal for teaching individuals of middle school …

Differences Between Stem Students And Faculty On Seeing Value In A Classroom Belonging Exercise, Kaisa S. Holt

OHSU-PSU School of Public Health Annual Conference

Efforts to enhance belonging in undergraduate STEM classrooms are believed pivotal for student success. However, we must not only promote belonging interventions but also understand STEM students and faculty perceptions of their value and utility. We gathered perspectives of faculty and undergraduates regarding the implementation and efficacy of a belonging exercise (Our Lives Lived, OLL) used in multiple STEM classes at one university over two years. We hypothesized that students would see more value in the exercise than faculty. We sent a survey instrument with an OLL summary and a series of open-ended responses to faculty. We recruited for focus …

Primary Health Care: Strengthening Health Systems In Low- And Middle-Income Countries, Erin Young

OHSU-PSU School of Public Health Annual Conference

In recent decades, global health priorities have shifted away from promoting selective, donor-led interventions and towards the goal of strengthening primary health care systems in low- and middle-income countries. This project seeks to identify recommendations for and best practices of primary health care system development from the existing literature. A critical literature review was conducted using the Ovid-MEDLINE database to identify articles that focused on primary health care, included recommendations for health systems strengthening, and addressed low- and middle-income countries. Ultimately, 27 articles published between 2004 and 2019 were included in this review. Results suggest that important priorities for building …

Universal Health Care, Oregon, Jennifer S. Arnold, Bethany Clouse, Alec Martin

OHSU-PSU School of Public Health Annual Conference

Historically, the US has chosen not to fund universal health care at every opportunity, leaving our nation as the only industrialized country without some system of health coverage for our citizens and with the worst health care outcomes of any high-income nation in the world. Health care in Oregon is no exception. Our current health care system is financially unsustainable, harmfully complex, and socially unjust, as well as inequitably delivered. Too many Oregonians, because of their race, age, income, geography, or insurance, endure vastly different health care access, varied health care quality, and wide-ranging health outcomes. In 2019, the Oregon …

Behind The Walls: The Implications Of Assisted Living Building Codes On Resident Safety, Adam Pennavaria, Lindsey Smith, Paula Carder, Cassandra Hua, Eric Jutkowitz, Kali Thomas

OHSU-PSU School of Public Health Annual Conference

As the US population collectively ages, issues related to assisted living (AL) resident safety have become an increasingly pressing issue for the general public, reflected by major media reporting in the last year. The building codes that govern ALs play an important role in mitigating the risks associated with falls, wandering, and other hazards, especially for residents living with Alzheimer’s disease and related dementias. We sought to understand how states vary in their approaches to building code regulations that might impact resident safety. We used search term-based text retrieval to identify areas of text relevant to locks, alarms, and egress …

A Method For Describing The Problem Of Physician Distrbution In Rural Areasralph Ekwall, Ralph Ekwall

The Geographical Bulletin

In recent years much attention has been given to the problem of physician shortage and physician maldistribution. The first is con­troversial and not all the experts believe that it exists except as a part of the maldistribution problem. There is a fundamental agreement that a problem of maldistribution exists. The general nature of the problem is that physicians are dis­tributed too densely in small cities and large city suburbs and too sparsely in the inner city and rural areas. It is not the intent of this presen­tation to offer a solution to the problem, but to offer a method for …

The Evaluation Of Four Time Intervals Applied To A Synoptic Weather Situation In The United State, Fred E. Kohle

The Geographical Bulletin

synoptic meteorology almost always utilize the easily acquired National Weather Service weekly series of daily weather maps, issued every 24 hours at 7 A.M. eastern standard time (E.S.T.). These daily surface maps provide students with weather data from hundreds of weather stations in the continental United States. Students can use each map to compare and contrast weather patterns affecting several different parts of the country. A sequence of these daily maps allows students to attempt general weather forecasting using well-known weather relationships associated with the model middle latitude cyclone. They can then evaluate their forecasts by referring to the next …

Application Of 700 Millibar Synotic Climatology To Drought Analysis, B. Dey

The Geographical Bulletin

Large areas of the earth's surface experience occasional climatic fluctuations. Such fluctuations, integral to the weather system, often lead to drought or flood, and this influences crop production and commodity prices. Drought is a contributor to economic, social, and, on occasion, even political instability in both commercial and subsistence agricultural econ­omics. Particularly affected are areas such as India, China, parts of Europe, and the American Great Plains which include the Canadian "Prairies". Because of its dominantly agricultural economy, and because of its location well within a zone of frequent drought, the Canadian Prairies section has been selected for study. Past …

Diffusion Of The Decision To Drain Agricultural Land In Delaware County, Indiana, T. Silas Kasambira, Jr.

The Geographical Bulletin

The amount and quality of land are vital production factors in agriculture. In some Indiana counties, the agricultural land resource base is limited by the presence of excess water. The decision to drain potential agricul­tural land in Delaware County, In­diana, and the subsequent diffusion of that innovation has increased the amount and quality of land available for agriculture. Draining agricultural land is a practice which began in the eastern United States and diffused rapidly across the country during the 1800's. The practice was introduced into northern Indiana, which has a great deal of flat, marshy terrain as early as 1850. …

Jonas Wenger Hoover - 1889-1979 Dr. Commeaux, Malcolm Commeaux

The Geographical Bulletin

Jonas Wenger Hoover, a faculty member at Arizona State University from 1924 to 1943 died recently at the age of 90. His life was somewhat like a roller coaster, reaching highs and lows; for the first half of his life he was considered a gifted, in­telligent, and well-rounded man, and he was highly regarded as an author and teacher, but for much of his life he lived in obscurity and near the bottom of society. He is a forgotten man today, but his life can be a lesson to us all. Mr. Hoover was considered gifted in several respects. He …

Facilitating The Use Of Sbar By Nursing Staff For Handoff Communication, Amarillis L. Tompkins

Student Scholarly Projects

Practice Problem: Clear communication during shift handoffs is crucial to minimize errors and ensure patient safety in intensive care. The current SBAR framework used in the MICU is constrained by limited documentation space, which led to communication inefficiencies and heightened risks for patient care.

PICOT: The PICOT question that guided this project was: In the NFSG VA MICU, will staff nurses (P) using a revised SBAR communication tool with a checklist (I), compared to the current outdated SBAR tool without a checklist (C), improve the accuracy and completeness of patient handoff communication (O) over eight weeks (T)?

Emotional Intelligence As A Moderator Between Depression, Loneliness, And Affect Intensity, Ryan Fleig

Theses and Graduate Projects

Emotional intelligence (EI) is a construct that has been present in psychology in various, non-specific forms for many years. Mayer and Salovey (1997) first created a specific construct of EI that centered on four key skills: emotion-perception; using emotions to facilitate thought; understanding one’s own and other’s emotions; and emotion regulation. Research on EI has largely been regulated to social domains, but some literature has established links between overall EI and specific EI skills and clinical symptoms such as depression and anxiety. The current study sought to further the literature on EI in clinical domains by studying correlations between emotion …

The Disrupted Symphony Of Speech: A Lesion Network Mapping Analysis Of Apraxia Of Speech, Payton Harris, Harrison Moore, Milija Grotenhuis, Jared Nielsen, Michael A. Ferguson

FHSS Mentored Research Conference

Apraxia of Speech (AOS) is a motor speech disorder that causes difficulty planning and coordinating the movements necessary for speech. This study uses lesion network mapping to identify the neural connections of AOS by tracing lesion data and analyzing their functional connectivity patterns. Our data indicates strong connectivity between the left primary motor cortex and right premotor cortex. The findings of the left primary motor cortex differ from most AOS research but still correlate with regional functions found in healthy populations. However, results related to the right motor cortex were much less expected, and suggested a larger, understudied role in …

Pain-Related Sleep Disturbance And Hazardous Alcohol Use Among Veterans With Chronic Pain, Alexa G. Deyo, Kyle Mackenzie White, Joon Kyung Nam, Victoria E. Carlin, Grant H. Ripley, Joseph W. Ditre

Voices of Service Symposium

Introduction: Pain-related sleep disturbances (PRSD) may contribute to patterns of alcohol consumption that elevate risk for negative health outcomes among U.S. military veterans with chronic pain, with this association potentially heightened among those who experienced combat. We are not aware of any prior research that examined either relations between PRSD and hazardous alcohol use among veterans, or the potential influence of combat exposure. The goal of this study was to test the hypothesis that PRSD would be positively associated with hazardous drinking among veterans, and that combat exposure would moderate this relationship. Method: Participants included 430 U.S. veterans (Mage = …

Cannabis Use, Psychological Distress, And Suicidal Ideation Among U.S. Veterans, Grant H. Ripley, Colin J. Jarrat, Joseph W. Ditre

Voices of Service Symposium

Introduction: Frequent cannabis use is rising among U.S. adults, particularly among those experiencing psychological distress. While Veterans generally report lower cannabis use than civilians, they face higher risks of mental health disorders, with approximately 17 Veterans dying by suicide daily. Understanding the relationship between cannabis use and psychological distress, particularly among Veterans with and without suicidal ideation, is crucial.
