Health promotion as a research area served three purposes: to inform the research questions, to direct the data collection, and to identify implications from the research findings. The four included studies explored how adolescents portray food in a widely used image-sharing application, why and how adolescents in treatment for obesity engaged with online health-related information, and how these adolescents experienced …

Phylogeographic Relationships Of Coereba Flaveola And Their Malaria Parasites, Meghann Humphries

Dissertations

This dissertation is broadly focused on elucidating how the geographic structure and demographic changes in host and parasite populations relate to one another, and how such interactions contribute to the generation and maintenance of biological diversity.

I begin by investigating the population structure of the Coereba flaveola (bananaquit) population within Puerto Rico, which is the apparent source of several expansions of the species into the Lesser Antilles. These findings indicate that both island and taxon effects influence the observed demographic changes. Because susceptibility to antagonists is related to both host species-specific characteristics and to geographical location, coevolutionary outcomes of these …

The Lived Experience Of Breastfeeding For Women With Perinatal Depression, Beth A. Pratt

Dissertations

Exclusive breastfeeding for at least 6 months provides numerous infant and maternal benefits. Yet mothers with risk factors, such as lower education, lower socioeconomic status, younger maternal age, planned cesarean birth, and anxiety and depression, are more likely to stop breastfeeding in the early postpartum period. Few studies have focused on perinatal depression as a risk factor for breastfeeding cessation. To tailor effective interventions, nurses must first understand the lived experience of breastfeeding for mothers at risk for perinatal depression. A descriptive phenomenological study was conducted to elucidate the experience of breastfeeding for mothers with perinatal depression. The study was …

Sociocultural, Physiologic, And Psychologic Variables That Influence Pain In The Fibromyalgia Patient, Linda Carol Hughes

Dissertations

It is estimated that fibromyalgia, a chronic condition in which pain occurs in 98% of the patients, can be found in 3- to 6-million American adults with females as the majority of those suffering. The purpose of this study was to determine variables that influence pain in women with fibromyalgia. The study's conceptual framework, based on Melzack and Casey (1968) and fibromyalgia literature, depicts the influence of three domains of variables on pain: sociocultural (i.e. age, education, ethnicity), physical (i.e. activity; comorbidity such as pelvic pain; flare-up; physical trauma; sleep-wake disturbance; fatigue; physical fitness) and psychologic (i.e. depression).

A Grounded Theory Approach To Explore The Experience Of Involuntary Childlessness In Couples With Infertility, Taylor L. Grube

Dissertations

Couples who experience involuntary childlessness as a result of infertility are challenged to manage the biological, sociological, and psychological implications of the situation. Furthermore, they are confronted with a variety of options regarding infertility management and resolution of involuntary childlessness. Nurses play a key role in supporting couples as they manage infertility and involuntary childlessness. Since infertility and subsequent involuntary childlessness is a couple's experience, nursing care should aim to meet the needs of both partners. However, there is a lack of evidence to suggest how couples experience and manage this phenomenon. Therefore, the purpose of this study was to …

Behavioral Indices Of Maternal Stress And Health Related Family Boundary Ambiguity In Pediatric Intensive Care, Bonnie L. Harbaugh

“Polysoaps” Via Raft Copolymerization To Form Well-Defined Micelles For Water Remediation And Targeted Drug Delivery Applications, Phillip Pickett

Dissertations

Amphiphilic copolymers have become increasingly important for environmental and biological applications due to their behavioral characteristics in aqueous solution. For example, structurally-tailored statistical amphiphilic copolymers or “polysoaps” can self-assemble into micelles or other architectures in water at various concentrations. Polysoaps may be differentiated from small molecule surfactant micelles in their capability to self-assemble into unimolecular associates (unimolecular micelles) with no dependence on concentration. Such micelles offer enormous potential for dispersion of hydrophobic species in water at high dilution. Importantly, each polymer chain forms its own micelle and upon dilution, these micelles remain intact and capable of dispersing hydrocarbon material in …

Research has shown patients who are communication impaired are at a greater risk of medical error and poorer health outcomes. A review of the literature revealed various nurse perceptions of barriers when providing care for limited-English-speaking patients and non-English-speaking patients. LEP and NEP patients also identified similar perceived barriers when receiving care. Both nurses and patients revealed a distrust for interpreters and interpreter services. The literature review revealed …

Bioinspired Glycopolymers: Models To Investigate The Effect Of Saccharide Structure And Concentration On Amyloid Beta Aggregation, Pradipta Kumar Das

Dissertations

Aggregation and subsequent deposition of amyloid-β (Aβ) peptide on neuronal cell membranes have been implicated as a cause of Alzheimer’s disease. Gangliosides in their clustered form seed and promote the Aβ aggregation process. However, the effects of the structure and the concentration of ganglioside saccharides on Aβ aggregation are not well understood. We investigated how the specific structure of saccharides (β-D-galactose and β-D-glucose) affect the aggregation pathways, kinetics, and the aggregated structures of Aβ via in vitro experiments. The effects of the local concentration of saccharides on the Aβ aggregation were also investigated.

The Importance Of Responsiveness: Improving Health-Related Outcomes Among Ostomates, Carrie Reif

Dissertations

More than 750,000 individuals in the United States live with an ostomy appliance, and additional 130,000 patients undergo ostomy surgery each year (United Ostomy Association of America, 2018). Although a life-saving procedure, patients confront significant physical (e.g., bowel routine and activity levels) and emotional (e.g., poor body image and depression) challenges that impede the adjustment process. When faced with health-related threats, the transactional action model of stress and coping argues that patients use strategies, such as seeking support, to effectively cope. However, because of perceptions of felt and enacted stigma and health-related uncertainty, some patients conceal ostomy-related issues and limit …

Nevertheless They Persisted: Youth Formerly In Foster Care Who Have Experienced Trauma And Their Journey To Postsecondary Education, Kristin Janine Myers

Dissertations

It is estimated that approximately 60% of children have experienced some form of trauma in their lifetime (Wiest-Stevenson & Lee, 2016). Research in the last 20 years has shown the impact of childhood trauma on human development, social development, and learning, and yet, there is very little literature in school counseling about this topic (Perry, 2001, 2006). School counselors play in essential role in identifying barriers that impede students from receiving a high-quality education (American School Counselor Association [ASCA], 2012), and are charged with reducing the educational attainment gap for the students they serve (Milsom & McCormick, 2015). There are …

First-Generation Community College Transfer Students’ Perceptions Of Building A Sense Of Belonging And Its Subsequent Impact On University Retention, Tara E. Benson

Dissertations

Although attendance numbers are rising in both populations, transfer students and firstgeneration students have lower retention and completion rates (Bonet & Walters, 2016; Seider, Clark, & Soutter, 2015). All students, specifically first-generation and transfer students, have a better chance of succeeding if they feel they are academically and socially integrated into the university setting (Seider et al., 2015; Williams & Ferrari, 2015). The purpose of this study was to examine the success gap between firstgeneration transfer students and continuing generation community college transfer students who attend one Midwest university. The mixed methods study included an analysis of quantitative data of …

The Role Of Plasmids And Clones In The Emergence Of Carbapenem Resistant Enterobacteriaceae In The United Arab Emirates, Shaimaa Fekry Mahmoud Mouftah Ali

Dissertations

Resistance to carbapenems, the ultimate beta-lactam antibiotics used to treat life-threatening Gram-negative infections associates with very high mortality. Consequently, carbapenem-resistant Enterobacteriaceae (CRE), which are usually multi- or extremely drug-resistant, is considered a critical pathogen. To help to control their spread, we investigated the molecular epidemiology of CRE in the United Arab Emirates (UAE) and its neighboring countries. CRE isolated in the UAE were screened for IncX3 incompatibility type plasmids carrying carbapenemases. The complete sequence of the IncX3 plasmids identified was established. Thirty CRE carried blaNDM-1, blaNDM-4, blaNDM-5, blaNDM-7, blaOXA-181, and blaKPC-2 on IncX3 plasmids. …

The Effects Of Exercise Training On Cachexia In Mice Bearing The Colon-26 Carcinoma, Nicole Wood

Dissertations

Colon cancer is third the most prevalent cancer in the United States in both men and women. However, it is also a largely preventable disease, as colorectal cancer (CRC) risk is increased by environmental factors such as poor diet and physical inactivity. Furthermore, CRC patients are highly susceptible to significant muscle wasting. Cachexia is classified as a multifactorial metabolic syndrome associated with impairments in immune function, fatigue, and overall weakness, that lead to increased morbidity and mortality. To date, multiple studies have shown that both aerobic and resistance training, individually, are highly effective in their ability to attenuate the deleterious …

Child Maltreatment And Physical Health In Emerging Adulthood: Relationships With Physical Activity And Health Risk Behaviors, Susannah Marie Moore

Dissertations

Child maltreatment is highly associated with physical health problems throughout the lifespan (Schafer, Morton, & Ferraro, 2014; Springer, Sheridan, Kuo, & Carnes, 2007). Yet much is still unknown regarding the trajectory of health problems including the onset of health risk indicators in emerging adulthood. Emerging adulthood also represents a unique timeframe with little demand for healthy behaviors. There is evidence that child maltreatment increases the involvement in health-risk behaviors such as substance use, risky sex, and binge eating (Downey, Gudmunson, Pang, & Lee, 2017; Röhr et al., 2015). The primary purpose of the current study was to examine if emerging …

A Study Of Beluga (Delphinapterus Leucas) Vocal Ontogeny, Audra Elizabeth Ames

Dissertations

There is a shortage of literature regarding beluga (Delphinapterus leucas) vocal ontogeny, as presently, there has only been one published study on the vocal development of beluga calves, despite the value of ontogenetic studies for our understanding of sound-centered species. Here I offer the second longitudinal study of beluga vocal development. Using a calibrated digital hydrophone with a sampling rate of 256 kHz, I studied the vocal progression of a male beluga calf in early life. From his first day, the calf produced broadband pulse trains with upper frequency limits extending past the study’s Nyquist frequency (128 kHz); …
