Testing For A Descriptive And Injunctive Norm Interaction In Promoting Health Behavior, Robert E. Low

Master's Theses

Social norms-based interventions have demonstrated efficacy as tools for behavior change interventions. Nonetheless, there is some theoretical and empirical evidence that the efficacy of injunctive norms-based appeals can be undermined by their tendency to 1) arouse psychological reactance among participants, and 2) inadvertently imply that few others are completing the target behavior. The author hypothesizes that supplementing an injunctive appeal with evidence of a supporting descriptive norm will counteract these problematic tendencies. The present research describes a test of of this hypothesis in the context of an intervention to fight H1N1 on campus. Boxes of sanitizing keyboard wipes were placed …

The Use Of Remote Sensing For Mapping Possible Vectors Of West Nile Virus In Mississippi, Brian Matthew Moore

Master's Theses

There is renewed interest in disease surveillance due to the persistence of numerous vector-borne diseases. Though the life-history processes of disease vectors are known to dictate their distribution patterns, it has been hypothesized that vectors, such as local mosquito abundance, could be predicted from factors such as climate and land use/land cover. Remote sensing has been used as a supplement to traditional methods of mosquito surveillance and to map the spatial distribution of mosquito habitats. This, in turn, affords optimism for improved vector/disease management to identify the best use of remote sensing data and geo-statistical techniques to predict and map …

Factors Influencing Ectoparasitism On Western Fence Lizards (Sceloporus Occidentalis): Host Sex, Testosterone, Reproductive Condition, And Behavior, Nicholas B. Pollock

Master's Theses

Host-parasite relationships are one of the most common symbiotic relationships present in a diverse array of ecosystems. There are numerous factors that impact the dynamics of these relationships. Major factors that can influence the degree of parasitism include host sex, hormonal state, reproductive condition, and behavior. It has been observed in several vertebrate taxa that males have higher ectoparasite intensities than females and males with increased testosterone have increased ectoparasite intensities. One potential reason for these observations is that testosterone concentrations are elevated in males, particularly during the breeding season, and when circulating concentrations increase males become more vulnerable to …

An Efficient Primer Selection Process Combining Progressive And Iterative Multiple Sequence Alignment Strategies: Clustalw And Hmmer, Michael C. Green

Master's Theses

This thesis describes a method for using a computationally efficient algorithm to identify candidate DNA primer sequences. DNA sequencing primers are a critical element of polymerase chain reaction (PCR) and DNA sequence analysis.  A variety of methods for deriving DNA primers exist, but such methods are often computationally intensive, or do not use available sequence data that could potentially serve as a possible resource for primer identification.  Though no current algorithm exists which will always yield a correct primer for every need, evaluation of multi-sequence alignments may provide a reliable source for primer candidates.  However, an exact mathematical solution for …

ATs work under the guidance of a physician, but little information is available regarding the perceptions of the aforementioned methods from the team physician’s perspective. Objective: To investigate team physicians’ practice beliefs regarding the …

The Effect Of Total Work Performed During Acute Heavy Resistance Exercise On Circulating Lymphocytes In Untrained Men, Neil A. Kelly Jr

Master's Theses

Lymphocytes are one of many leukocytes which exert a biphasic response to acute intense resistance exercise. Exercise volume (i.e. total work) has been shown to have an immunomodulatory effect. This study evaluates the effect of total work performed during an intense resistance exercise protocol on lymphocyte concentrations in the circulation. Untrained, college-aged (18-35) males who performed high amounts of work (HW) were compared to those who performed low amounts of work (LW). Resistance exercise testing consisted of 6 sets of 10 repetitions of the squat exercise with 2 minutes rest between sets. Both HW and LW performed the same relative …

Discovery And Molecular Characterization Of Selenoprotein M In The Salivary Glands Of Amblyomma Maculatum, The Gulf Coast Tick, Parul Singh

Master's Theses

The Gulfcoast ticks transmit disease-causing pathogens to humans and animals. Rickettsia parkeri is notable among the pathogens transmitted by A. maculatum to humans. Heavy infestations of A. maculatum on animal ears cause them to become thickened and curled, a condition commonly called "gotch ear." The tick's multifunctional salivary glands are vital to their biological success and likely also play a critical role in transmission of disease; tick saliva contains a broad array of secretory products that facilitate prolonged tick attachment and feeding; disrupting tick blood feeding or inactivating key tick salivary proteins presents a novel strategy for tick-borne disease prevention. …

Optimization Of Point-Of-Use Water Treatment Device For Disaster Relief, Margaret June Herzog

Master's Theses

Point-of-use (POU) drinking water treatment is a common method of providing drinking water in disaster relief situations when critical water infrastructure is damaged. In these cases, POU treatment devices can be used to treat local water until relief organizations set up more permanent water provision methods. One such POU technology is PŪR^® Purifier of Water, a combined coagulation/flocculation and disinfection chemical treatment sachet produced by Procter & Gamble. PŪR^® has been shown to treat contaminated water to meet water quality standards and guidelines set by the U.S. EPA for water purifiers and by the World Health Organization and …

This study investigated dental students' prejudicial beliefs towards underserved patient populations as an upstream constituent of provider attitudinal barriers to care. The objectives were to explore the nature of prejudicial beliefs, to assess the value of critical reflection as essential preparation for patient care, and to identify insights that would inform the preclinical curriculum that, ultimately, reduce oral health disparity.

An original reflection assignment was introduced into the preclinical curriculum of first year dental students to journal about the legitimacy of their prejudicial beliefs. Results indicated dental students identified a range of prejudicial beliefs and, through self-direction, experienced awareness and …

Contributory Factors Of Extraneous New Bone Growth On The Endocranial Surfaces Of Human Infant And Sub-Adult Skeletal Remains, Mark Andrew Zahareas

Master's Theses

This study investigates the factors that may contribute to endocranial bone changes in human sub-adult skeletal remains in an effort to differentiate bone changes, or lesions, caused by pathological processes and those caused by growth and development. The contributory factors investigated included the presence of endocranial bone lesions, the age-at-death of the individual, the precise location of the bone change, the dynamic nature of the locations, and the presence (or absence) of postcranial and/or ectocranial indicators of pathology within the individual. The sample population used for this research was comprised of 129 individuals from 15 different Native American groups over …

Role For Histone Deacetylases In Glucocorticoid Receptor Mediated Transpression Of Natural Killer Cell Activity, Kristin Bush

Master's Theses

During periods of psychosocial distress glucocorticoids (GCs) are known to reduce the lytic activity of natural killer cells (NKCA). Glucocorticoid treatment also reduces acetylation of histone residues; however, the glucocorticoid receptor (GR) lacks deacetylase activity. GR is known to interact with histone deacetylases (HDACs) and with corepressors that mediate gene transrepression. In this investigation, GC induced histone deacetylation was demonstrated to be due to GR recruitment of HDAC1 and the corepressor complex SMRT. These data show that reduced acetylation of immune functional genes associated with NKCA is likely due to histone deacetylation by HDAC1 and transrepression of those genes by …

The Influence Of Neuroticism On Stress Perception And Its Resultant Negative Affect, Irum Saeed Abbasi

Master's Theses

There is contemporary literature reporting the role of the neuroticism (N) personality type in the stress process. People with elevated neuroticism experience more interpersonal stressors, perceive daily events as more negative, and use maladaptive ways to combat stressors. This thesis explores the influence of neuroticism on stress perception and the associated negative affect. In the current study, mood and stress perception of pre-screened college students who scored high and low on the neuroticism subscale were manipulated, with a laboratory psycho-social stressor, after their moods were initially neutralized to their respective base levels. Later, their mood and stress perception were manipulated …

City Of San Luis Obispo: Community And Municipal Operations 2005 Baseline Greenhouse Gas Emissions Inventory, Geoffrey M. Chiapella

Master's Theses

The passage of AB 32 in 2006 initiated the need for city planners in California to consider the quantification of greenhouse gas emissions at the community level in order to develop policies and programs to reduce emissions in the future. Although local jurisdictions are not required to quantify and report emissions at this time, the AB 32 Climate Change Scoping Plan recommended a reduction goal for local governments of 15 percent below today’s levels by 2020 to ensure consistent reduction goals at the state and local levels.

ICLEI-Local Governments for Sustainability initiated the Cities for Climate Protection (CCP) campaign in …

Phenotypical And Functional Analysis Of Peripheral T Cells In Foxn1 Transgenic Mice: Effects Of Aging, Paulette Krishack

Master's Theses

The thymus is the primary organ for the development and production of TCRαβ naive T cells. However, with increasing age thymic involution occurs, causing a decline in the output of naïve T cells. The decline in naïve T cell production results in a contraction in the peripheral naïve and expansion of the memory T cell pools. Not only are the production and compositions of peripheral T cells altered with age, T cell functions such as T cell proliferation and production of cytokines required for cell proliferation are also declined. Currently, it is not known if restoring the decline in the …

Structure-Function Relationship Studies Of The Udp-Glucose Pyrophosphorylase From Escherichia Coli, Agnieszka Maria Orlof

Master's Theses

UDP-Glucose Pyrophosphorylase (UDP-Glc PPase) is a key enzyme of the carbohydrate metabolic pathway widely used among prokaryotes and eukaryotes. In plants, UDP-Glc PPase is necessary for sucrose synthesis while mammals utilize this enzyme for the production of glycogen. A bacterium such as Escherichia coli uses UDP-Glc PPase for biosynthesis of the lipopolysscharide core which forms a cell wall.

This study focused on UDP-Glc PPase from Escherichia coli which is encoded by both galU and galF genes. The first part of this project investigated amino acids that could play an important role in the function of UDP Glc PPase (GalU). Based …

Functional And Phenotypical Analysis Of The Effects Of Aging On B Cells And Their Bone Marrow Microenvironment, Nicole May Ziegler

Master's Theses

Aging impacts multiple organ systems, and specifically causes the immune system to lose its ability to efficiently fight off infections. Regarding immunity, aging research predominantly focuses on the adaptive immune system. B cells, which mediate the humoral arm of the adaptive immune system, develop throughout life in the bone marrow where microenvironmental `niches' are important. The bone marrow does not exactly `atrophy' with age; however, studies comparing young and old mice demonstrate an age-related change in the bone marrow B cell subpopulations.

The overall goal was to determine if femoral and sternum bone marrow have different plasma cell composition and …

The Effect Of All-Trans Retinoic Acid And Fatty Acids On Mcf-7 Breast Cancer Cell Progression, David A. Brown

Master's Theses

Vitamin A metabolites and retinoids may slow the progression of breast cancer and elicit anti-neoplastic properties similar to those of omega-3 fatty acids. Studies using animal models show a decrease in the incidence, growth and metastisis of mammary tumors in the presence of specific fatty acids. This effect is also seen with use of retinoids, specifically all-trans retinoic acid (AtRA). Thus, fatty acids may also alter retinoid homeostasis in mammary carcinoma cells (MCF-7s). The potential for inter/co dependency among fatty acids and retinoids is considerable, and here it has been hypothesized that a decrease in cancer progression will occur in …

Shrines And Prayers: Two Missing Elements Of Comprehensive Mass Fatality, Rhonda Keyes Pleasants

Master's Theses

As a Licensed Funeral Service Provider, I am aware of the special issues which surround mass fatalities. A study of numerous mass fatality plans yielded identification of two missing elements from most plans which are critical to mass fatality management. The first missing element is ritual used in the respectful treatment of the dead. The second missing element is religious precepts regarding caring for and final disposition of the dead based upon the particular belief system of the deceased, their family, surrounding community, and culture. Specific qualitative methods of research used were a review of the professional literature, identification of …

Hospital Volunteers: A Study Of Motivation, Judith Blanchard

Master's Theses

This study was conducted using in-depth interviews of 21 hospital volunteers to determine what motivations were operative in their choice to volunteer in a hospital and to determine whether any significant differences with regard to their motivation could be ascertained on the basis of age or gender. The study further probed the satisfaction and needs of these volunteers relative to their choice and motivation.

The study found that a combination of altruistic concerns, personal interests, and needs were fundamental to the study participants' volunteer choices. No clear differences in motivation were found on the basis of gender. Retirement from employment …
