The Effect Of Acculturation On Equine Assisted Psychotherapy Satisfaction With Indigenous Populations, Reagan Joseph Alsbaugh

Theses and Dissertations

Past research has suggested that equine-assisted psychotherapy may be an effective, culturally relevant treatment modality for Indigenous individuals with substance-use disorders. The literature also suggests that mental health outcomes may be mediated by an Indigenous individual’s level of acculturation. It was hypothesized that individuals who were traditional or bicultural would report higher levels of satisfaction with their experiences in equine therapy than those who are assimilated or marginal. There were 17 Native American participants who had completed at least 4 weeks of an equine-assisted therapy program who participated in the study. Of the participants, 8 were traditional and 9 were …

Improving Health Literacy In Diagnostic Imaging For Indigenous Populations: Evaluating Practices, Integrating Policy, And Bridging Gaps, Kimberly Harn

Theses and Dissertations

Indigenous populations in the United States and internationally experience persistent disparities in healthcare access, patient communication, and health outcomes, including disproportionate cancer mortality rates and inequitable engagement with diagnostic imaging services. Communication barriers, limited health literacy, historical trauma, cultural incongruence, and structural inequities reduce meaningful participation in imaging-related care and contribute to delayed diagnosis and poorer outcomes. Despite the critical role of diagnostic imaging in disease detection and clinical management, the intersection of Indigenous health, health literacy, patient communication, and cultural safety within diagnostic imaging contexts remains substantially understudied.

This applied dissertation addresses that gap through three integrated scholarly products …

Qualitative Exploration Of Understanding Gluten Intolerance: Knowledge, Experiences, And Perceptions Among American Indian Adults Living On The Mandan, Hidatsa, And Arikara Nation, Roselle M. Martin

Theses and Dissertations

Background: This dissertation examines gluten intolerance, particularly celiac disease (CD), within American Indian communities. Although CD has been traditionally considered more common among people of European descent, emerging evidence suggests increasing rates among American Indian populations as dietary patterns have shifted from traditional, naturally gluten-free foods to diets containing higher levels of gluten. These dietary changes, along with possible genetic factors and historical underdiagnosis, highlight the importance of understanding how gluten-related health concerns are recognized and discussed within American Indian communities. Lower rates of diagnosis may reflect limited awareness of symptoms and challenges in communicating gluten-related health experiences rather than …

Testing The Efficacy Of A Non-Invasive, Epidermal, Marker-Based Method For Conducting X-Ray Reconstruction Of Moving Morphology (Xromm) On A Cadaver Chicken, Brian Skillman

Theses and Dissertations

X-Ray Reconstruction of Moving Morphology (XROMM) is widely used to understand the kinematics of living organisms. The first of two standard methods for utlizing XROMM is to surgically implant X-ray dense markers within the bones of interest and euthanize the subject at the conclusion of testing, referred altogether as marker-based. The other standard, known Scientific Rotoscoping, or markerless, involves using thorough videography of the subject and manual bone orientation within the data collection program. These standards both pose unique issues, such as post-surgery complications for marker-based and time constraints for markerless. We investigate an intermediate method for utilizing XROMM involving …

Nurse Manager Perceptions Of Strategies To Overcome The Underutilization Of Nonpharmacological Pain Control Methods In Adult Acute Care, Landen M. Bonnell

Undergraduate Honors Theses

A basic patient right is to have pain adequately managed. However, research consistently indicates that many adult patients in acute care experience inadequately managed pain, which may contribute to adverse patient outcomes. Studies have shown that nonpharmacological pain management can lead to increased patient satisfaction, shorter hospital stays, and better patient outcomes. However, many barriers exist to nurses providing effective nonpharmacological pain control therapy, primarily including heavy workload and a lack of education and support. Currently, there is insufficient research on how to overcome these barriers. Four nurse managers with experience in nursing leadership were interviewed using a qualitative descriptive …

Transnational Indigenous Environmental Justice: A Distant Comparative Study Of Nepali And U.S. Environmental Policies And Counter-Archives In Technical Communication, Shankar Paudel

Open Access Theses & Dissertations

This dissertation investigates how institutional communication, state bureaucracy, and Indigenous sovereignty intersect within Rhetoric and Writing Studies (RWS) and Technical and Professional Communication (TPC). Current TPC research increasingly focuses on social justice; however, the field still lacks ethical frameworks to deal with the complicated dynamics of transnational Indigenous Environmental Justice Communication (IEJC). This study addresses this gap by examining how two distinct Indigenous communities - the Tharus of Chitwan, Nepal, and the Ysleta del Sur Pueblo Tigua Indians of El Paso, Texas - communicatively navigate, contest, and resist state environmental policies.

From Screening To Risk: Assessment Of Potentially Toxic Elements In Children's Toys Along The El Paso, Tx, U.S.A.-Ciudad Juarez, Chih, Mex Border Region, Jesus Rodriguez-Loya

Open Access Theses & Dissertations

Children are uniquely vulnerable to potentially toxic elements (PTEs), absorbing them more readily than adults and encountering them through the hand-to-mouth behaviors of early childhood. Exposure carries element-specific consequences: lead (Pb) impairs cognitive development with no established safe threshold; cadmium (Cd) damages the kidneys and reduces bone mineralization; arsenic (As) is a recognized carcinogen and developmental neurotoxicant; hexavalent chromium (Cr) is carcinogenic and induces allergic dermatitis; nickel (Ni) is the leading cause of allergic contact dermatitis in children; and excess zinc (Zn) disrupts copper absorption and causes gastrointestinal distress. Toys are a distinctive source of such exposure, yet none had …

An Evaluation Of Staff Training To Teach Implementation Of Functional Analysis Of Inappropriate Mealtime Behavior, Lauren Marie Lightner

Theses and Dissertations

Avoidant/Restrictive Food Intake Disorder (ARFID) along with other feeding disorders are prevalent in both neurotypical children along with children diagnosed with autism spectrum disorder (ASD) and other developmental disabilities. Children with feeding challenges often exhibit inappropriate mealtime behavior (IMB) to avoid consuming non-preferred foods. It is pertinent to determine the function of IMB in order to create an efficacious treatment; one such assessment is the functional analysis (Iwata et al. 1982/1994). Iwata et al. (2000) taught students how to implement a functional analysis of self-injurious behavior using behavioral skills training. Since the assessment’s development, it has been extended to various …
