The Development And Testing Of The Codependency-Overeating Model In Undergraduate Social Science Students In A Mississippi College, Denise Bynum

Dissertations

Overeating is a common eating disorder and often leads to obesity and to significant physical, emotional and social problems often warranting nursing care. The psychological and behavioral factors surrounding overeating are noted frequently in the literature, but are not emphasized in most prevention and treatment programs for overeating. Codependency has expanded beyond the chemical dependency field and describes the dysfunctional pattern of behavior of an individual in a relationship with another person or from survival in a dysfunctional family of origin. This pattern of behavior includes the neglect of personal needs, focus and dependency on others, boundary/control issues, low self-worth …

Understanding The Posttranslational Regulation Of The Response Regulator Rcsb And Acetyl Phosphate As An Acetyl Group Donor In E. Coli, Linda Hu

Dissertations

The observation that Nepsilon-lysine acetylation occurs on a hundreds of proteins in bacteria is a recent discovery. To study the mechanisms that regulate acetylation and to determine if acetylation affects physiology, I studied the Escherichia coli response regulator and transcription factor RcsB, which was reported to be acetylated in vitro. To monitor RcsB activity, I measured transcription from the rprA promoter, which requires RcsB. I confirmed that RcsB is activated by phosphorylation through the Rcs phosphorelay and acetyl phosphate and showed that acetyl phosphate could phosphorylate RcsB. However, a mutant that accumulates acetyl phosphate (ackA) exhibited reduced rprA transcription instead …

High School Curriculum Tracks As Determinants Of Post-Secondary Outcomes: A Study Of Track Mobility And Its Effects, William Morrison

Dissertations

Despite scores of studies that have shown that tracking and ability grouping perpetuate the academic achievement gap that exists in the United States, the practice continues. The reason for this persistence is a confluence of educational, social, and political factors. As tracking will continue as practice for the foreseeable future, research must help to identify the best and worst of tracking practices so that its negative effects are minimized and positive effects maximized. Oakes (2005) has identified five common elements of tracking policies and practices: extent, pervasiveness, flexibility, mobility, and locus of control. Of these elements, it is my contention …

Characterization Of The Novel Response Regulator Sype: A Dual Regulator Of Biofilm Formation And Colonization In Vibrio Fischeri, Andrew Robert Morris

Dissertations

Biofilms, or surface-associated microbial communities encased in a matrix, represent a common mode of growth for many bacterial species. Importantly, biofilms often play significant roles in the association of bacteria with their animal hosts, including promoting attachment to and colonization of host tissues. The symbiosis between the bacterium Vibrio fischeri and its animal host Euprymna scolopes provides a natural model system for investigating the impact of biofilms on host infection. In particular, V. fischeri produces a specific biofilm to successfully initiate host colonization.

Biofilm formation by V. fischeri is a tightly regulated process involving a complex network of regulatory genes. …

A Descriptive Study Of The Leadership Role Of Community Health Ambassadors On Diabetes-Related Health Behaviors, Barbara Pullen-Smith

Dissertations

Diabetes is a chronic disease that bears a disproportionate burden among African American populations. The lack of access to affordable, culturally appropriate health care is a key barrier to effective diabetes prevention or disease management for racial/ethnic minority populations. Living in public housing communities, with concentrated poverty, exacerbates the burden of diabetes and reduces access to screening and early detection services to prevent the onset of diabetes. The purpose of the study was to describe the leadership role of lay health advisors, known as Community Health Ambassadors (CHAs), on diabetes-related health behaviors of African Americans living in a public housing …

Use Of Sweet Potato To Develop A Medium For Cultivation Of Lactic Acid Bacteria, Saeed A. Hayek

Dissertations

This study investigated the use of sweet potatoes (Ipomoea batatas) as a basic component to develop a medium for cultivation of lactic acid bacteria (LAB). Extract from baked sweet potatoes was used to form a sweet potato medium (SPM). SPM was supplemented with 4 g/L of each nitrogen source (beef extract, yeast extract, and proteose peptone #3). Lactobacilli MRS was used as a control medium. Ten LAB strains were used to determine the suitability of SPM serving the growth of LAB. Our results showed no significant (p < 0.05) differences in the optical density, maximum specific growth rates, and bacterial populations between MRS and SPM. SPM also maintained higher pH values throughout the incubation period compared to that in MRS. The cost of SPM was 47% less than the cost of MRS. Further step was taken to determine the suitability of SPM serving LAB enzymatic activity. LAB strains growing in SPM showed relatively higher β-glucosidases, acid phosphatase, and phytase activities and lower a-glucosidase compared to that in MRS. Strains of L. reuteri showed the …

Are Women Aware? : Factors Related To Women's Knowledge Of Risk And Preventive Factors In Breast Cancer, Sandra M. Walther

Dissertations

Problem. Women have a one-in-eight chance of being diagnosed with breast cancer in their lifetime. In the past decade, there has only been a decrease of less than 1% in breast cancer morbidity and mortality rates. Breast cancer continues to be a feared disease that ravages even its survivors, and grips many with fear. Furthermore, breast cancer remains the highest cost of care among cancers. In 1990 the overall cost of care for breast cancer was $4.2 billion. In 2010, the total cost of breast cancer care rose to almost $17 billion, and by 2020 the cost trends show …

The three overarching questions addressed in this study were: What inter-agency involvement is necessary in implementing a successful re-entry program? What are the …

Going Beyond Phosphorylation: Acetylphosphate-Mediated Ran Polymerase Acetylation And Caper Phosphorylation Co-Regulate Transcription Of Escherichia Coli Stress-Responsive Gene Cpxp, Bruno P. Lima

Dissertations

The ability of bacteria to sense and adapt to environmental changes has al-lowed these organisms to thrive in all parts of the globe and to establish many complex interactions with the environments they live as well as other members of these environments. Crucial to monitoring extracellular conditions is a group of signaling pathways known as two-component signal transduction system (2CST). These systems relay information from the extracellular environment to the interior of the cell via a transfer of phosphoryl groups from the sensory protein know as sensor kinase (SK) to the output protein known as response regulator (RR).

In addition …

Caregivers Of Older Adults: Burden, Perception Of Strain, And Health, Juana Ferrerosa Phd, Msn, Rn, Phn

Dissertations

Background: By the year 2030, the older population in the United States is projected to double from 35 to 70 million. Consequently, increasing the number of informal caregivers required to care for an aging population. Research suggests that levels of caregiver strain and their ability to cope can impact the health of caregivers. Tsai's (2003) Middle-Range Theory of Caregiver Stress guided this study and was modified to present an innovative approach which used perceived caregiver strain as a specific stressor in the Control Process of the model; it provided a basis for examining caregiver strain and its effect on the …

Marine Fungi Of U.S. Gulf Of Mexico Barrier Island Beaches: Biodiversity And Sampling Strategy, Allison Kathleen Walker

Dissertations

Marine fungi are an important but often overlooked component of marine ecosystems. Primarily saprotrophic, they are vital to coastal nutrient cycling processes and food webs. However, basic marine fungal distribution data are lacking in many parts of the world, as is knowledge of the sampling intensity required to characterize the biodiversity of these communities. The roles of substrate, season and latitude in shaping intertidal ascomycete community structure were examined for the U.S. Gulf of Mexico, and the role of sampling frequency on species richness estimates was also addressed. Best sampling practices were developed and 750 collections of beach detritus, sand …

Management Of Biological And Chemical Constituents For The Advancement Of Intensive, Minimal-Exchange, Biofloc-Based Shrimp (Litopenaeus Vannamei) Aquaculture, Andrew James Ray

Dissertations

Intensive, minimal-exchange, biofloc-based shrimp aquaculture systems may provide a sustainable alternative to traditional shrimp culture. Through a series of experiments, this document explores the effects of several key management strategies on water quality, isotopic distribution, and shrimp production.

An experiment evaluated the effects of managing suspended solids (biofloc) concentration at two levels. It was found that using a higher flow rate to larger settling chambers resulted in significantly lower biofloc and nitrate concentrations, and significantly improved shrimp growth rate. A second experiment compared systems with clear water and systems with biofloc. The filters in the clear water systems prevented biofloc …

Activity Of The Beta-Cyanoalanine Synthase Pathway Is Associated With The Response To Abiotic Stress By Arabidopsis Thaliana., Marylou Machingura

Dissertations

Cyanide is produced throughout a plant's life cycle alongside the hormone ethylene by oxidation of 1-aminocyclopropane-1-carboxylic acid. Production increases during certain developmental stages such as seed germination, seedling elongation, fruit ripening and senescence. Abiotic stresses increase ethylene production giving rise to `stress cyanide'. Cyanide also comes from metabolism of cyanogenic compounds. Cyanide is however, a toxic chemical which readily binds to metallo-enzymes inhibiting primary metabolic processes. Plants have mechanisms to maintain cyanide homeostasis such as the β-cyanoalanine pathway whereby cysteine reacts with cyanide forming β--cyanoalanine, mediated by β-cyanoalanine synthase and cysteine synthase. A dual nitrilase 4 enzyme then converts the …

Specifically, this study evaluated whether real-time prompts delivered via a one-way radio would result in immediate and sustained increases in rates of DCS positive interactions. Additionally, this study evaluated the link between increased rates of DCS positive interactions and concomitant decreases in residents’ challenging behaviors. A multiple baseline design across participants was implemented to assess DCS rates of positive and negative interactions. …

Living With Attention Deficit Hyperactivity Disorder, Chalonda Henry

Dissertations

Attention Deficit Hyperactivity Disorder is a commonly diagnosed disorder for both children (and today adults). The literature discusses how ADHD is defined as research continues, the symptoms demonstrated by those diagnosed, how it has been known to affect their main life areas e.g. home, school, social relationships, and how it is assessed, diagnosed and treated. However, reading the literature does not give the reader a sense of the real life perception of ADHD. Children with ADHD and parents of children with ADHD participated in an interview consisting of nine open ended questions. The results were found to be consistent with …

Preschool Curriculum: Choices That Promote Learning, Renee Curet Criddle

Dissertations

Ongoing research has shown that preschool is beneficial not only to early childhood success, but also in providing long-term benefits (Wong, Cook, Barnett, & Jung, 2008). With standards for early childhood being generated at the national level with the announcement of the common core standards nationwide and at the state level through state-mandated early learning guidelines and benchmarks, preschools are turning to specified curriculum content and mandated outcomes for early education programs. Effects of preschool programs vary (Barnett et al., 2008) due to differences in program curriculum and method of delivery. As the knowledge and understanding of how young children …
