Speaking For The Families: Organizational Socialization Of Military Spouses In Volunteer Leader Positions, Virginia Klaus

Murray State Theses and Dissertations

Military spouses holding volunteer leadership positions in military unit family readiness groups, provide a link between commanders and families of service members. They act within military organizations as the only official voice of spouses, a stakeholder group recognized as influential in retention rates and force readiness. Despite their importance, military spouses are often portrayed in research as passive members, taking on roles to meet the expectations of their peers and military organizations. That contradicts historical evidence of military spouses as active organizational members who have socialized other spouses, and as family advocates who have challenged military organizational practices and policies. …

The Effect That Positive And Negative Self-Concepts Have On Adolescents' Behavior And Personalities, Portia L. Davis

Murray State Theses and Dissertations

Soil Nutrient Sufficiency Versus Plant Nutrient Status In Compost-Amended Soils: Plant Tissue Analysis As A Diagnostic Tool, Chandralekha Joga Miss

Murray State Theses and Dissertations

This study evaluated whether Mehlich III soil nutrient sufficiency ratings reliably predict plant nutrient status and chlorophyll response across contrasting compost application histories. A greenhouse pot experiment was conducted with Chijimisai (Brassica rapa) planted in three treatment soils that had no compost (T1), moderate compost history (T2), and long-term hog manure compost application (T3). Plant performance was assessed through weekly shoot length and chlorophyll content (SPAD) measurements, leaf number at maturity, and leaf tissue nutrient analysis conducted at harvest. Soil test results indicated adequate to high nutrient levels across all three treatments. Leaf tissue analysis, however, revealed substantial …

Classifying Surfaces With Handle Decomposition, Elizabeth Sipes

Murray State Theses and Dissertations

Among topological spaces, manifolds draw a lot of interest. An
n-manifold is a space that is locally like R^n. Manifolds of dimension 2
are called surfaces. Using handle decomposition, we decompose surfaces
into k-handles, where 0< =k< =2. Techniques such as handle sliding and
handle cancellation allow us to get a more favorable representation of
our surface. We use these tools and calculation of the fundamental group
to classify all compact surfaces.

Wired For Inclusion: Leveraging Strengths Of Neurodivergent Special Educators, Brok Hess, Teresa Clark Ed.D.

Don’T Give The Fae Your Name: Focus Of Attention And Victim Blaming, Entropy Cramer

Murray State Theses and Dissertations

Victim-blaming is thought to be a result of the fundamental attributional error, where people over-emphasize internal attributions about the victim. Despite this, there is little literature on manipulating the focus of attention and the result for victim-blaming. People who are high in rape myth acceptance tend to visually focus on the victims longer (Süssenbach et al., 2015). Rempala and Bernieri (2005) found that adding irrelevant information, such as height and weight, to the trial about the victim increased victim-blaming compared to when it was absent. The current study investigated if relevant information about the victim and perpetrator changed the amount …

The Weight Of Stigma, Rebekah A. King, Michael S. Sinha

All Faculty Scholarship

Many health care providers, both implicitly and explicitly, perpetuate stigma in their treatment of patients classified as obese. While medical professionals understand that a one-size-fits-all approach to treatment is ineffective, patients classified as obese are frequently offered limited treatment options that fail to account for their unique needs. Access to a range of effective treatment options has historically been limited, but new GLP-1 receptor agonist medicines like Wegovy (semaglutide) and Zepbound (tirzepatide), have shown incredible promise in addressing the obesity crisis. Unfortunately, these transformative drugs are costly, in high demand, and not widely covered by insurance, rendering them inaccessible for …

The Asexual Assumption, Faith K. Whatley-Blaine, Michael S. Sinha

All Faculty Scholarship

Inclusion-focused dating shows such as ‘Love on the Spectrum’ feature individuals with developmental or neurological disabilities on a quest for love. Despite the focus on disability representation, these shows perpetuate stigma against the disabled community by fostering an infantilizing portrayal of individuals with disabilities. This portrayal undermines the premise of encouraging meaningful romantic relationships and reinforces the stigmatizing association of asexuality with disability. This framing aligns with the broader societal narrative that individuals with disabilities are incapable of or lack interest in participating in romantic relationships or physical intimacy.

The stigma that associates asexuality with disability extends beyond mere entertainment, …

From Reactionary To Anticipatory Integrated Action: Novel Environmental Health Surveillance For Mass Gatherings, Benjamin J. Ryan, Michael Donahoo, Danielle Esler, Paul Barach, Benjamin Coghlan, Shelby Garner, Laura M. Langan, John Piispanen, Bryan W. Brooks

College of Population Health Faculty Papers

Advances in AI-driven analytics, human-in-the loop techniques, and wastewater monitoring provide the foundation needed to shift from reactive to anticipatory actions for mass gatherings. Traditional surveillance systems focus on clinical and laboratory-based notification pathways, which often result in tardy actions being implemented. Thus, traditional surveillance is becoming outdated. Mass gatherings pose heightened public health risks and hazards, including trauma; injury and substance misuse; deliberate poisoning; and infectious diseases such as food and waterborne illnesses, sexually transmitted infections, and respiratory diseases. There is also a heightened concern due to reduced vaccination coverage. As a result, future international events such as the …

All Peer-Reviewed Publications

Introduction:

Human African trypanosomiasis (HAT), caused by Trypanosoma brucei rhodesiense, is categorized as acute due to rapid disease progression but presents varying clinical outcomes. Although the mechanisms underpinning differential clinical progression are poorly understood, both host and parasite factors are implicated. Therefore, we sought to elucidate roles of primate host factors in mediating varying T. b. rhodesiense infection outcomes.

Methods:

Here, we assessed the roles of selected host cytokines in disease progression using a tsetse-mediated infection in a non-human primate (NHP) vervet monkey model that closely mimics HAT and natural infection. We quantified eight cytokines, including TNF-α, IFN-γ, IL-10, IL-6, …
