Human services professionals (HSPs) are poised to contribute to interprofessional collaboration (IPC) in Integrated Behavioral Health (IBH) settings as care enhancers. Interprofessional Education (IPE) effective for training HSPs requires changes or addition to curriculum. The purpose of the current study was to present workshops adjunct to curriculum to HSPs targeting their engagement in IBH settings. The study explored their self-efficacy with IPC after such training using a pre- and post-test design. Results indicated a statistically significant increase in self-efficacy from before and after the workshop. Discussion includes implications for human services educators in using workshops to augment the IPE their …


Pharmaceutical Messianism And The Politics Of Covid-19 In The United States, Gideon Lasco, Vincen Gregory Yu, Nishtha Bharti Jan 2024

Pharmaceutical Messianism And The Politics Of Covid-19 In The United States, Gideon Lasco, Vincen Gregory Yu, Nishtha Bharti

Development Studies Faculty Publications

Throughout the COVID-19 pandemic, public officials in the United States–from the President to governors, mayors, lawmakers, and even school district commissioners–touted unproven treatments for COVID-19 alongside, and sometimes as opposed to, mask and vaccine mandates. Utilising the framework of ‘pharmaceutical messianism’, our article focuses on three such cures–hydroxychloroquine, ivermectin, and monoclonal antibodies–to explore how pharmaceuticals were mobilised within politicised pandemic discourses. Using the states of Utah, Texas, and Florida as illustrative examples, we make the case for paying attention to pharmaceutical messianism at the subnational and local levels, which can very well determine pandemic responses and outcomes in contexts such …

Geographical Variation In Songs Of Bachman’S Sparrow (Peucaea Aestivalis), L. Nguyen, K. Doñas, J. Jackson, R. Kannan

Journal of the Arkansas Academy of Science

We present an analysis of geographic variation in primary song components of the Near Threatened North American endemic, Bachman’s Sparrow (Peucaea aestivalis). These songs have 2 distinct portions: an introductory tweet we call the "whistle" and a more complex second portion that we call the "trill". We analyzed 327 songs from 111 recordings downloaded from eBird.org from the entire current range of the species. We grouped the recordings into 3 distinct geographic clusters, East, Central, and West. The data measured from spectrograms suggest a significant statistical difference among groups for 3 measured characteristics: frequency range of trill, number of horizontal …

Energy Content Of Acorns Of Shinnery Oak (Quercus Havardii) In The Diet Of Scaled Quail (Callipepla Squamata) In Southeastern New Mexico, J.L. Hunt, M.E. Grilliot, T.L. Best, D. Lozano-Lopez, E.R. Neilson, I.C. Castillo

Journal of the Arkansas Academy of Science

Shinnery oak (Quercus havardii) is a deciduous, low-growing shrubby tree that is a dominant plant in large areas of grassland in western Oklahoma, the Texas Panhandle, and eastern New Mexico. Acorns of the plant are important food items for many wildlife species, including scaled quail (Callipepla squamata), mourning doves (Zenaida macroura), and endangered lesser prairie-chickens (Tympanuchus pallidicinctus). We analyzed the energy content of acorns of shinnery oak obtained from the crops of scaled quail collected from plains-mesa sand-scrub in Lea and Eddy counties, New Mexico. Acorns were removed from crops and dried for 48 hours at 60°C to remove moisture …

This review explores the challenges of the transition from caregiving to widowhood and different coping strategies used by widowed spousal caregivers. A systematic review of literature on the transition from caregiving to widowhood was conducted using four major academic search engines. Overall, 280 articles were identified, with 22 meeting the inclusion criteria. Challenges for widowed caregivers included experiencing care burden, letting go of the caregiver role, grief, and triggers. Widowed caregivers’ coping strategies included social support and services use, filling the time gap, finding spirituality, …


Us Hospices’ Approach To Racial/ Ethnic Minority Inclusion: A Qualitative Study, M. Courtney Hughes, Erin Vernon, Monica Kowalczyk, Marlon Basco-Rodillas Jan 2024

Us Hospices’ Approach To Racial/ Ethnic Minority Inclusion: A Qualitative Study, M. Courtney Hughes, Erin Vernon, Monica Kowalczyk, Marlon Basco-Rodillas

Faculty Articles, Papers, and Other Scholarship

Objective: To examine hospices’ approaches to improving the current racial/ethnic hospice utilisation disparity.

Methods: During June and July 2020, we conducted in-depth, semistructured interviews with 22 hospice leaders from across the USA. The interviews focused on inclusive strategy approaches. We analysed the data using qualitative methods.

Results: Multiple themes emerged about racial/ ethnic minority inclusion strategies: (1) hospices tailor strategies to the local communities they serve; (2) improvement involves addressing social determinants of health that extend beyond end-of-life care; (3) costs of strategies are not a primary concern and the benefits are worth the costs; and (4) hospices want to …

Using a strengths-based resilience framework, this study sought to determine culturally relevant protective predictors of self-esteem for Black women who are justice-involved and have HSV-2. The authors conducted secondary data analysis on data from the “Black Women in the Study of Epidemics (B-WISE) Project,” a longitudinal prospective study investigating health disparities and health services utilization among Black women with justice involvement. At baseline, N = 151 Black women with HSV-2 who were incarcerated or on probation completed survey measures assessing selfesteem, ethnic identity affirmation …


Addressing Healthcare Disparities Faced By Aging Down Syndrome Populations, Rhea Mistry Jan 2024

Addressing Healthcare Disparities Faced By Aging Down Syndrome Populations, Rhea Mistry

Pitzer Senior Theses

Down syndrome (DS) is a chromosomal genetic condition that impacts the development of the body and brain. The life expectancy of individuals with DS has drastically improved over the decades, increasing from 9 years in 1929 to 25 years in 1983 and further reaching 60 years by 2002. Individuals with DS face a variety of prominent co-occurring health conditions that are subject to change over time, including cognitive, visual, and hearing impairments, sleep apnea, cardiovascular defects, Down syndrome regression disorder, and dementia. Despite this increase in life span, DS is still most familiar to pediatric care providers, resulting in healthcare …

A Survey Of Strongyle Nematodes In New England Dairy Goats, D.J. Richardson, E.M. Wray, D. Watters, U. Hanif, E. Jalbert, E. Thompson, G. Trajkovic, A.R. Sirois, N. Pilotte

Journal of the Arkansas Academy of Science

The paucity of information concerning the occurrence of strongyle nematodes in New England dairy goats prompted a survey of 241 dairy goats from throughout New England. Of the 241 goats examined using the McMaster technique, 104 (42.7%) were infected with strongyles with a mean intensity (+ SE) of 369.7 + 45.8 eggs per gram. Subsequent molecular examination of 50 random samples from these goats revealed a prevalence of 88% infection specifically with Haemonchus contortus. Haemonchus contortus is the most important internal parasite of sheep and goats, exerting a crushing economic burden on the livestock industry worldwide due to lowered milk …

Bat Versus Ant: The First Report Of Evening Bat/Ant Interaction In Arkansas, J.D. Wilhide, D.B. Sasse, R.P. Kelso

Journal of the Arkansas Academy of Science

This paper documents the first reported occurrence of bat/ant agonistic interaction in Arkansas and the second report involving Evening Bats (Nycticeius humeralis). An adult male Evening Bat was captured during a presence / absence mist net survey along Highway 412 in Black Rock, Lawrence County, Arkansas on 4 June 2023. The bat weighed 12.0 g and had a forearm length of 36.94 mm which is in the midrange for evening bats in Arkansas (Sealander and Heidt 1990). The evening bat had two ant head capsules attached to its right cheek and at the tip of the lower lip (Fig. 1).


The Integrated Behavioral Model Of Mental Health Help Seeking (Ibm-Hs): A Health Services Utilization Theory Of Planned Behavior For Accessing Care, Joseph H. Hammer, David L. Vogel, Patrick R. Grzanka, Nayeon Kim, Brian T. Keum, Claire Adams, Sarah A. Wilson Jan 2024

The Integrated Behavioral Model Of Mental Health Help Seeking (Ibm-Hs): A Health Services Utilization Theory Of Planned Behavior For Accessing Care, Joseph H. Hammer, David L. Vogel, Patrick R. Grzanka, Nayeon Kim, Brian T. Keum, Claire Adams, Sarah A. Wilson

Chemical and Materials Engineering Faculty Publications

This article introduces the integrated behavioral model of mental health help seeking (IBM-HS), a theoretical model for understanding the constructs (e.g., systemic, predisposing, and enabling factors; mental health literacy; illness perceptions; perceived need; stigma; shame; perceived benefits, motivation) that influence people’s decision making around seeking professional mental health care and their ultimate access to formal treatment. The IBM-HS is a help-seeking-specific adaptation of the empirically supported integrated behavioral model and integrative model, which are themselves evolutions of the theory of planned behavior and theory of reasoned action. The IBM-HS posits that help-seeking determinants (e.g., structural forces; cultural influences; past help-seeking …


Burnout In Athletic Training: Measured By Survey In Most Common Settings For Athletic Trainers, R Johnson Krug, N Sand, S Brooks, T Smith Jan 2024

Burnout In Athletic Training: Measured By Survey In Most Common Settings For Athletic Trainers, R Johnson Krug, N Sand, S Brooks, T Smith

Clinical Practice in Athletic Training

Introduction: Burnout is a common problem in athletic training, affecting both athletic trainers (ATs) and the athletes they serve. Athletic trainers are responsible for the prevention, diagnosis, and treatment of sports-related injuries. Long work hours, often including evenings and weekends, as well as frequently under pressure to meet the demands of athletes, coaches, and parents. Athletic trainers face numerous stressors that contribute to burnout. These stressors may include heavy workloads, lack of control over their schedules, time pressures, and pressure to produce positive outcomes. Athletic trainers may also experience emotional and physical exhaustion, depersonalization, and a reduced sense of personal …

Educational Outcomes Of The Dat: A Document Review And Thematic Analysis, S H. Orr, L E. Eberman, M J. Rivera

Clinical Practice in Athletic Training

Context: The transition in athletic training education allows for unique and new opportunities in postprofessional education. The Doctor of Athletic Training (DAT) degree is one of the postprofessional education pathways that could provide athletic trainers advancement in clinical practice, practice leadership, and scholarship. However, there is no data on the educational outcomes of DAT programs and what graduates should expect from their experiences. The aim of this study was to explore whether DAT programs are delivering curricula consistent with the development of clinical scholars with advanced knowledge and skills that are needed for high-level patient care and literature relative to …


Using Data In The Classroom To Drive Instructional Design And Delivery, L E. Eberman, J P. Young Jan 2024

Using Data In The Classroom To Drive Instructional Design And Delivery, L E. Eberman, J P. Young

Clinical Practice in Athletic Training

Introduction: Roughly half of ATP program directors include education on transgender health care in their programs, and even fewer report having the competence to do so. However, professional-level accreditation standards (56, 57, and DEI 2) require that programs have faculty with contemporary expertise to educate students on these outcomes. Current research suggests a comprehensive transgender and sexual health curriculum, including safe-zone training, traditional lecture, lab, and project-based instruction, was partially effective at changing students’ attitudes toward transgender patients but did not improve sexual health care delivery during a standardized patient encounter. The purpose of this project was to evaluate the …


Exploring The Work-Related Quality Of Life Of Athletic Trainers In Physician Practice, N T. Anderson, K E. Games, J P. Young, M J. Rivera, L E. Eberman Jan 2024

Exploring The Work-Related Quality Of Life Of Athletic Trainers In Physician Practice, N T. Anderson, K E. Games, J P. Young, M J. Rivera, L E. Eberman

Clinical Practice in Athletic Training

Introduction/Context: The National Athletic Trainers’ Association (NATA) identified the vitality of the athletic training profession as a research priority, which includes exploring solutions to improve work-life balance. There is a common perception that athletic trainers (AT) working in the physician practice setting have lower work-life conflict and increased job satisfaction, but no data to support this belief. Work-Related Quality of Life (WRQoL) has been studied in some healthcare settings but has not been studied in any athletic training clinical practice setting. Therefore, the purpose of this study is to investigate the WRQoL of athletic trainers in physician practice. Methods: A …


I Am Not A Hero: Heroic Action Divorces The Hero From The Political Community, Ari Kohen, Brian Riches, Andre Sólo Jan 2024

I Am Not A Hero: Heroic Action Divorces The Hero From The Political Community, Ari Kohen, Brian Riches, Andre Sólo

Department of Political Science: Faculty Publications

Most people who perform a heroic act will, afterward, deny that their actions were heroic and claim that anyone would have done the same, even though that is demonstrably false (and, often, others were present who failed to act heroically at all). The literature on the psychology of heroism has never investigated why this is. This theoretical paper proposes an answer and seeks to provoke exploration of a previously unexplored topic. We note that people who undertake heroic action face a unique conflict: they embody their community’s highest values, while simultaneously breaking norms to stand apart from that community. We …


"The Most Important Thing In Ipv Right Now": The Intersection Of Intimate Partner Violence And Brain Injury, Halina (Lin) Haag Jan 2024

"The Most Important Thing In Ipv Right Now": The Intersection Of Intimate Partner Violence And Brain Injury, Halina (Lin) Haag

Theses and Dissertations (Comprehensive)

The intersection of intimate partner violence (IPV) and brain injury (BI) has been almost entirely overlooked in research, practice, and policy, despite the known risks associated with the two conditions. Individually, IPV and BI are associated with elevated rates of unemployment, poverty, and homelessness, as well as increased mental health challenges. These social determinants of health, employment status, and income impact women’s wellbeing through access to safe accommodations, food security, and (dis)ability supports. These determinants are also related to an increased likelihood of experiencing addictions, mental health challenges, and physical danger, potentially leaving women vulnerable to ongoing violence. This qualitative …

Fantasia On A Theme Of Purpose: Using A Music-Guided Scribble Technique To Support Meaning-Making In Older Adult Retiree Musicians, Sophia R. Smith Jan 2024

Fantasia On A Theme Of Purpose: Using A Music-Guided Scribble Technique To Support Meaning-Making In Older Adult Retiree Musicians, Sophia R. Smith

Art Therapy | Master's Theses

Within the population of older adults, overall well-being corresponds with the ability to self-actualize and seek meaning, but age-related changes combined with ageism and isolation can negatively impact this capacity to maintain a sense of purpose, especially following retirement. It may be that retired musicians are especially vulnerable to this experience later in life due to a loss of the primary method of creative engagement and community that is facilitated by musical performance in a group setting. Integrating phenomenological and ethnographic approaches, this study utilized a qualitative design to understand how music-guided art-making incorporating the scribble technique could support a …


Distal Urogenital Anatomy And Epithelial Morphology In The Male Cajun Chorus Frog, Pseudacris Fouquettei (Anura: Hylidae), S.E. Trauth Jan 2024

Distal Urogenital Anatomy And Epithelial Morphology In The Male Cajun Chorus Frog, Pseudacris Fouquettei (Anura: Hylidae), S.E. Trauth

Journal of the Arkansas Academy of Science

I examined the microanatomy of the distal urogenital system in male Cajun Chorus Frogs (Pseudacris fouquettei) from a small sample (n = 6) collected in central Arkansas in March 2018 and February 2023. Specifically, my primary objectives were to investigate the following: (1) the paired Wolffian (urogenital) ducts caudally from the kidneys to their merging with the urodeum of the cloaca, (2) the structure of seminal vesicles (if present), and (3) the epithelial morphologies among the distal urogenital tract, the posterior alimentary canal, and cloaca. My histological analysis confirmed the presence of ampullae (sperm storage structures) as mid-duct expansions of …


Use Of Google Earth Streetview To Evaluate Nesting By The Cliff Swallow (Petrochelidon Pyrrhonota) In Lowlands Of Eastern Arkansas, With Reports Of New Records, R. Tumlison, Z. Autrey Jan 2024

Use Of Google Earth Streetview To Evaluate Nesting By The Cliff Swallow (Petrochelidon Pyrrhonota) In Lowlands Of Eastern Arkansas, With Reports Of New Records, R. Tumlison, Z. Autrey

Journal of the Arkansas Academy of Science

Cliff Swallows (Petrochelidon pyrrhonota) typically construct their mud nests under the overhangs of cliffs. However, construction of concrete bridges and overpasses has provided suitable nesting structure in the last few decades. As the number of such nesting sites have increased, the breeding range also has expanded. We evaluated the use of Google Earth Streetview as a means of cheaply harvesting data regarding nesting distribution. The gourd-shaped nests of Cliff Swallows were easily discernible via available imagery, and we were able to document previously unreported nest sites of this species in 6 counties in eastern Arkansas (5 from imagery, 1 from …


Shell Damage Patterns In Limpkin Mussel Middens At Bois D’Arc Lake, Arkansas, G.R. Graves Jan 2024

Shell Damage Patterns In Limpkin Mussel Middens At Bois D’Arc Lake, Arkansas, G.R. Graves

Journal of the Arkansas Academy of Science

The Limpkin (Aramus guarauna) is rapidly colonizing the lower Mississippi Valley from recently established Gulf Coast populations. Anecdotal reports indicate that it feeds on freshwater mussels and gastropods in Arkansas, but without documentation. Here I report an analysis of Limpkin shell middens from Bois d’Arc Lake in Hempstead Co. Limpkins at this location preyed heavily on Pyganodon grandis (Giant Floater), a large mussel species widely distributed in the Mississippi Valley. Limpkins employ vigorous bill blows to pierce holes in mussels and usually attack the anterior end of the shell. Video and photographs of feeding birds provide new insight on the …


X-Ray Diffraction And Petrographic Analysis Of Magnet Cove Carbonatite Core, Arkansas, R.E. Mero, D. Mayo, M.P. Testa Jan 2024

X-Ray Diffraction And Petrographic Analysis Of Magnet Cove Carbonatite Core, Arkansas, R.E. Mero, D. Mayo, M.P. Testa

Journal of the Arkansas Academy of Science

Geothermal activity such as hot springs are known to precipitate calcium carbonate (CaCO3) minerals, producing rocks such as tufa, travertine and sometimes associated with carbonatite. The precipitation of CaCO is caused by the reduction of CO, which is less soluble in warmer waters. Geothermal heating of water in natural springs drives this precipitation of CaCO3 in areas of Arkansas including Magnet Cove. Magnet Cove, Arkansas is an alkalic igneous rock complex that is composed of a series of ring dikes post-Mississippian in age. These dikes have intruded into faulted and folded Paleozoic sedimentary rocks. One of these igneous dikes is …
