Addressing Health Disparities In The Rural United States: Advocacy As Caregiving Among Community Health Workers And Promotores De Salud, Ryan I Logan, Heide Castañeda

All publications

Rural populations in the United States are faced with a variety of health disparities that complicate access to care. Community health workers (CHWs) and their Spanish-speaking counterparts, promotores de salud, are well-equipped to address rural health access issues, provide education, and ultimately assuage these disparities. In this article, we compare community health workers in the states of Indiana and Texas, based on the results of two separate research studies, in order to (1) investigate the unique role of CHWs in rural communities and (2) understand how their advocacy efforts represent a central form of caregiving. Drawing on ethnographic, qualitative data—including …

Identification Of Bovine T-Cell Populations Involved In Placental Growth And Development, Kelsy A. Leppo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Today, the dairy industry is comprised of cows that can produce around 20,000 pounds of milk in a year, yet producers often see only 30% to 50% of animals produce a live calf after each breeding. While many factors may be at play, there is evidence that the immune system plays a large role in regulating pregnancy and in preventing immune mediated abortions. Maternal immune system changes during pregnancy have been shown to occur both locally in the uterus, which is in direct contact with the placenta, and systemically in the blood. Research in humans and mice has shown that …


Electrical Identification Of Innate Immune Cells, Rasha Ayman Nasser Dec 2020

Electrical Identification Of Innate Immune Cells, Rasha Ayman Nasser

Theses

This thesis is concerned with the electrical characterization of the key players of the innate immune cells. Innate immunity is basically the nonspecific immune response that is triggered by any foreign body that attacks the human system. The key players of the innate immune system are mainly dendritic cells and macrophages. Accurately classifying these cell types helps us understand the mechanism of the immune system thereby enabling the development of models to improve new prospects for therapeutics and diagnostics. The characterization described in this thesis is based on extracting the capacitance for each biological cell using I-V curves. The main …

Sensory Approach To Self-Regulation For Adolescent Survivors Of Sex Trafficking: An Occupational Therapist's Perspective, Elyse Harmon Dec 2020

Sensory Approach To Self-Regulation For Adolescent Survivors Of Sex Trafficking: An Occupational Therapist's Perspective, Elyse Harmon

Student Capstone Papers

Adolescent survivors of sex trafficking (SST) are susceptible to being in a continual dysregulated arousal state due to lack of mastery in self-regulation. During the trafficking experience, many adolescent SST experience severe trauma and are deprived of opportunities that foster essential regulatory capacities needed for occupational engagement. The use of sensory-based approaches that focus on addressing arousal dysregulation and the impact it has on occupation is an evidence-based practice grounded in occupational therapy research.

This capstone sought to support community reintegration for adolescent SST through the development of sensory-based programming that fosters self-regulation, a skill necessary for occupational participation. A …

Nurses' Attitudes Toward Physician-Assisted Suicide, Cheyenne Star Lowrey-Lagrone Dec 2020

Nurses' Attitudes Toward Physician-Assisted Suicide, Cheyenne Star Lowrey-Lagrone

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Physician-assisted suicide, or PAS, is end-of-life option in which patients self-administer physician-prescribed lethal medication to end their life. Nurses' own interpretations and understandings of the legalities, ethical dilemmas, and factors that influence their attitudes can be analyzed to determine the nurses’ role in the support or opposition of the practice. Although nurses do not have an active role in PAS, they play a pivotal role in patient advocacy and education. This paper analyzes the factors that contribute to nurses’ attitudes toward the practice, along with the benefits of education of this topic going forth.
