Does Appearance Matter? The Relationship Of Perceived Body Size And Physical Appearance On Students' Attraction To Physical Activity At Recess, Danielle Belcher

Master's Theses

Drastic declines in recess physical activity (PA) have been observed within recent years (Center for Disease Control (CDC), 2017). Due to recess’ discretionary nature, psychosocial variables associated with PA are predictors of students’ PA levels. Recess is also a time of heightened bullying occurrences (Vaillancourt et al., 2010). Appearance-based bullying is the most common type of victimization that occurs in schools, transpiring more often in children with larger body max indexes (BMI), and possibly altering students’ physical self-perceptions. Physical self-perceptions have been shown to impact PA motivation, however, it is still unknown the extent to which appearance-based bullying, body size, …

Assessing Health Implications Of Monarch Butterfly Populations And Behaviors, Kira Goldman, Kelsey E. Fisher Dr.

Honors Scholar Theses

Pollinator populations have seen massive declines over the past decade due to anthropogenic activity and climate change posing serious threats to the health of humans and ecosystems (Ulyshen & Horn, 2023). As agents responsible for the production of about 35% of micronutrient rich food crops necessary for adequate nutrition to lead healthful lives and prevent nutrition associated diseases, pollinator decline is a public health concern (Aizen et al., 2009). Monarch butterflies (Danaus plexippus) serve as bio indicators for the health of pollinator populations because of their analogous habitat and food resources shared with many other pollinator species, including bees and …

Analysis Of Antibiotic Sensitivity Patterns In Pasteurellaceae Family Isolates: A Microbial And Molecular Investigation, Jillian Barron

Honors Scholar Theses

Bacteria in the Pasteurellaceae family are known to cause disease in both human and animal species. Like all species of bacteria, the pathogens in the Pasteurellaceae family evolve and acquire antimicrobial-resistant traits. Antimicrobial resistance of bacteria is a significant public health concern, as treatment of resistant pathogens becomes more difficult, if not impossible, with current medical capabilities. In this project, phenotypic and genotypic analyses were performed on Pasteurellaceae family isolates sourced from the Connecticut Veterinary Medical Diagnostic Laboratory. Phenotypic antibiotic sensitivity patterns of each isolate were assessed against a panel of antibiotics through a Kirby-Bauer disk diffusion test. Disk diffusion …

Spatial Hearing In Simulated Reverberant Classroom Environments, Gabriel Seth Evan Weeldreyer

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

Spatial hearing provides access to auditory spatial cues that promote speech perception in noisy listening situations. However, reverberation degrades auditory spatial cues and limits listeners’ ability to utilize these cues for segregating target speech from competing babble. Hence, spatial unmasking—an intelligibility benefit from a spatial separation between a target and masker—is reduced in reverberant environments as compared to free field. This work tests the hypothesis that interaural decorrelation, the result of increasing reverberation, will broaden the perceived auditory source width with a cascading effect of reduced auditory spatial acuity and subsequently poorer spatial unmasking. To understand the perceptual consequences of …

This study investigates the women novelists' perspective toward the failure of male authored works to represent women's childbirth experience. Through a critical reading of Flora Nwapa's Efuru and Buchi Emecheta's The Joys of …

The Sexual Trauma Of The Female Body: Violence Against Women In Contemporary Spanish And Latin American Cultures, Lara Armenteros Garrido

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation focuses on the idea that women’s bodies have a sexual stigma attached to them as a consequence of different forms of heteropatriarcal violence inflicted on them. From violence in public spaces, such as street harassment or the sexual exploitation of women, to the intimacy of the relationship, like intimate partner violence or the orgasm gap, it becomes increasingly difficult for women to escape violence. Through the analysis of films, documentaries, narratives, and the testimonies of women from Spain and Latin America, I argue there is still a lack of adequate sexual and emotional knowledge to help complete agency …

A Comparative Analysis Of Hiv/Aids In France And The United States: Historical Context And Preventative Actions, Rebecca A. Liebsack

Honors Program: Senior Projects (Public)

The HIV/AIDS pandemic is the result of transmission of a zoonotic disease known as simian immunodeficiency virus. The pandemic has had profound social and economic consequences and continues to be present today. France and the United States’ response to the discovery of HIV will be compared and the impact that HIV/AIDS had on their countries and future responses. They had rather similar responses, however, the United States had a slower initial response compared to France. Both had similar takeaways such as aiming at improving prevention and utilizing tactics developed during the start of the pandemic like frequent testing and vaccines.

Exploring Binding Pockets In The Conformational States Of The Sars-Cov-2 Spike Trimers For The Screening Of Allosteric Inhibitors Using Molecular Simulations And Ensemble-Based Ligand Docking, Grace Gupta, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

Understanding mechanisms of allosteric regulation remains elusive for the SARS-CoV-2 spike protein, despite the increasing interest and effort in discovering allosteric inhibitors of the viral activity and interactions with the host receptor ACE2. The challenges of discovering allosteric modulators of the SARS-CoV-2 spike proteins are associated with the diversity of cryptic allosteric sites and complex molecular mechanisms that can be employed by allosteric ligands, including the alteration of the conformational equilibrium of spike protein and preferential stabilization of specific functional states. In the current study, we combine conformational dynamics analysis of distinct forms of the full-length spike protein trimers and …

Effect Of Progesterone On Cognition Among College Aged Women, Katelyn Helberg

Biological Sciences Undergraduate Honors Theses

Women who have a reoccurring menstrual cycle and do not take hormonal birth control naturally experience changes in the amount of sex hormones that their body produces. These sex hormones help promote sexual development, fertility, and mood regulation, but can be hard to study due to their conflicting effects on each other. One such hormone, progesterone, is produced in different concentrations throughout the menstrual cycle to prepare the uterus for a potential pregnancy. However, it also may have secondhand effects on how well women can complete everyday tasks involving memory, attention, processing speed, and more which is what we measured …

A Multimodal Approach To Decreasing Hesitancy Of The Influenza Vaccine In The Family Care Setting, Carley J. Ellenberger

Evidence-Based Practice Project Reports

The uptake of the influenza vaccine is the most effective and proactive action an individual can take to defend themselves against the influenza outbreak each season; therefore, it is recommended that everyone at least six months of age and older should receive the annual flu vaccine (CDC, 2022; WHO, 2023). Unfortunately, influenza vaccine hesitancy is demonstrated on a global level affecting the uptake compliance annually each influenza season despite the millions of people that experience influenza symptoms annually (CDC, 2022, WHO, n.d.; Healthy People 2030, n.d.). The PICOT question for this project was in adults, over the age of 18, …

Cost-Effectiveness Analysis Of Alternative Screening Strategies For The Detection Of Cervical Cancer Among Women In Rural Areas Of Western Kenya, Christopher Lobin, Elkanah Omenge, Edwin Were, Kapten Muthoka, Kavita Singh, Manuela De Allegri, Konrad Obermann, Magnus Doeberitz, Hermann Bussmann

Obstetrics and Gynaecology, East Africa

While the incidence of cervical cancer has dropped in high-income countries due to organized cytology-based screening programs, it remains the leading cause of cancer death among women in Eastern Africa. Therefore, the World Health Organization(WHO) now urges providers to transition from widely prevalent but low-performance visual inspection with acetic acid (VIA) screening to primary human papillomavirus(HPV) DNA testing. Due to high HPV prevalence, effective triage tests are needed to identify those lesions likely to progress and so avoid over-treatment. To identify the optimal cost-effective strategy, we compared the VIA screen-and-treat approach to primary HPV DNA testing with p16/Ki67 dual-stain cytology …

Reframing Addiction As A Coping Response: A Needed Shift In Modern Public Health Paradigms, Anthony King

UNLV Theses, Dissertations, Professional Papers, and Capstones

What are the primary risk factors that compel one person towards addiction and not another? After decades of research, there is still no clear consensus. Some experts say addiction is a brain disease; others say it is a willful act, or even an outright crime. Nevertheless, the three research studies contained within this dissertation suggest an alternative, more parsimonious public-health-centered framework for viewing addictive behavioral patterns: as a biopsychosocial coping strategy for past and present stressors. In Study 1, this idea was examined by evaluating how symptoms of posttraumatic stress disorder (PTSD) were associated with problem gambling severity, different gambling …

However, caregiving can be difficult and stressful that adversely impacts caregivers’ health. The extra stress brought on by the COVID-19 pandemic can potentially aggravate health problems, particularly mental health. The current research aimed to nationally analyze whether the COVID-19 pandemic was significantly associated with behavioral health (physical activity and smoking), mental health (worrying, nervousness, hopelessness, little interest, and psychological distress score), and the perception of overall well-being among informal caregivers in the United States. Whether behavioral health could mediate …

Examining The Risks And Resilience Of Older Adults Living With Hiv/Aids: Qualitative Community-Based Participatory Research Studies In Southern Nevada, Brandon Ranuschio

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since the height of the HIV pandemic in the 1980s, medical interventions have significantly increased the life expectancy of people living with HIV/AIDS (PLWH) and made HIV/AIDS a livable, chronic health condition. Because of this, PLWH have been living longer lives and thriving with the help of HIV sector healthcare and service providers. However, with their longer life expectancy, older PLWH have been experiencing other health challenges. One such challenge is the risk of developing HIV-Associated Neurocognitive Disorder (HAND), which is a condition that affects up to 50% of PLWH at some point in their lifetime, with middle-aged and older …
