The Role Of Cortisol In Modern Society: Linking Psychosocial Stress And Health, Logan Dwayne Fair
The Role Of Cortisol In Modern Society: Linking Psychosocial Stress And Health, Logan Dwayne Fair
Honors Theses
Glucocorticoids are a class of steroid hormones, which can act on almost all cells in vertebrate tissue through binding to glucocorticoid receptor. Cortisol, which falls into this class, is released in response to stress and provides our bodies with the necessary energy to cope with a wide variety of stressors. This function of cortisol is brought about through its action on numerous metabolic and immunological pathways. However, when cortisol levels remain elevated for extended periods of time, many of these acute effects of cortisol can bring about long-term health problems, including many associated with metabolic S5mdrome, such as obesity and …

Sã Se Puede... ¿Leer?: Assessing The Success Of The Cuban And Nicaraguan Literacy Initiatives, Camille Lyn Lesseig
Honors Theses
This research examines the literacy programs conducted in 1961 Cuba and 1980 Nicaragua. Given the similarities in the structure and implementation of the plan as well as the congruencies in rhetoric promoting the plans, this thesis explores the various internal and external variables that affected each country’s program to better understand the widely different results. To research these countries’ programs, I examined both primary and secondary source material related to each country, their educational programs specifically, as well as information about US foreign policy relationships with the countries during this time. Although both programs were initially successful in reducing illiteracy …
Healthcare Reform In Context Of The Unique Case Of Mississippi's Diabetic Population, Alley Estelle Ronaldi
Healthcare Reform In Context Of The Unique Case Of Mississippi's Diabetic Population, Alley Estelle Ronaldi
Honors Theses
Healthcare reform in the United States is a highly complex issue that is influenced by a number of economic, social, and political factors. These factors have converged in Mississippi to exacerbate reliance on acute care and the high costs associated with tertiary-level diabetes treatment. It has been thoroughly researched that continuous primary care is most the cost effective and convenient treatment for diabetes, yet such treatment centers are scarce in Mississippi due to healthcare payment structures. It is for these reasons that Mississippi is used as an excellent test case for reform proposals. Two of the most polar and popular …
Conditioned Place Preference As A Means To Measure Analgesic Drug Effects On Cancer Pain In Murine Models, Hannah Elizabeth Burson
Conditioned Place Preference As A Means To Measure Analgesic Drug Effects On Cancer Pain In Murine Models, Hannah Elizabeth Burson
Honors Theses
Pain associated with cancer is unpredictable and may reflect an inability to quantify it in animals. We hypothesize that Conditioned Place Preference (CPP) testing is sensitive to pain relieving drugs in animal models of cancer pain and that CPP scores will reflect varying degrees of pain relief To test this, mice were assigned to one of four groups: tumor or non-tumor groups conditioned to saline or morphine during preference testing. After baseline preference testing in the CPP apparatus, animals received either saline or morphine in the S+ chamber (initially non-preferred chamber). All animals received saline in the S- chamber (initially …

Food Preparation Habits Among College Students: An Exploration And Culinary Intervention, Mary Lindsey Simpkins
Food Preparation Habits Among College Students: An Exploration And Culinary Intervention, Mary Lindsey Simpkins
Honors Theses
The obesity rate among Americans has been growing at an alarming rate in recent years; because of this, there has been much inquiry into the possible causes, interventions, and prevention methods for this problem. One major trend that appears to have an impact on this obesity epidemic is the large proportion of meals eaten outside the home namely, at fast food or sit-down restaurants. This trend is especially prevalent among college students, whose lifestyle is generally marked by an abundance of stress coupled with a lack of time and money. Because of this lifestyle and a lack of food preparation …

The Causes And Effects Of Chinese Investment In Africa, Jamey Hurst
The Causes And Effects Of Chinese Investment In Africa, Jamey Hurst
Honors Theses
China’s engagement in Africa represents a radical departure from the modem paradigm of development. To the West, it represents a threat to the “Washington Consensus” and the accepted aid paradigm, but to African countries, the Chinese are providing much desired investment. Due to a paucity of information on this subject, this research aims to consolidate perspectives on this type of investment and identify factors leading to as well as the possible effects of the China-Africa relationship. This is accomplished by contextualizing the China-Africa relationship within a wider discourse on development, and then separating African countries on the basis of total …
Memphis Taxpayer Blues: An Economic Analysis Of The Memphis Pilot Program, Norman Lee Morris Iii
Memphis Taxpayer Blues: An Economic Analysis Of The Memphis Pilot Program, Norman Lee Morris Iii
Honors Theses
This thesis evaluates the economic impact of targeted tax cuts in Tennessee. Specifically, I examine the Payment-In-Lieu-Of-Taxes (PILOT) Program in Memphis, TN Using economic data supplied from the Federal Reserve Bank of St. Louis s Federal Economic Data and the Bureau of Labor Statistics, I consider the effectiveness of the program’s ability to improve economic conditions in Memphis, TN. The merits of a targeted tax cut program such as PILOT are often touted as the total number of jobs created and amount of dollars invested into the community. However, this method of counting the total number of jobs created overstates …
Antibiotic Resistance Of Bacteria Isolated From Leafy Green Salad Vegetables, Brooke Elizabeth Reynolds
Antibiotic Resistance Of Bacteria Isolated From Leafy Green Salad Vegetables, Brooke Elizabeth Reynolds
Honors Theses
Bacterial isolates obtained from samples of five varieties of leafy green vegetables were tested for resistance to four different antibiotics: ampicillin. erythromycin, streptomycin, and tetracycline. Isolates were separated based on media type (TSA vs. R2A media), sterilization techniques (surface sterilized vs. unsterilized). cultivation methods (conventional vs. organic), and specific lettuce type origins. Resistances were tested using a microscale broth culture technique, which allowed for growth of isolates in the presence of different concentrations of antibiotic. Antibiotic resistance was observed in all groups of isolates, although levels of resistance varied depending on the particular isolate and the antibiotic tested. Isolates were …
On The Fringes Of Peripheries: A Comparison Of The Working-Class Representations Of Larry Brown And Irvine Welsh, Christopher Paul Patterson
On The Fringes Of Peripheries: A Comparison Of The Working-Class Representations Of Larry Brown And Irvine Welsh, Christopher Paul Patterson
Honors Theses
In this thesis, I compare the fiction of Mississippi author Larry Brown and Scottish author Irvine Welsh, specifically in how they represent their respective regions’ working classes. The project concerns the genre of working-class fiction in both the American South and Scotland, as well as the general fields of Southern and Scottish contemporary fiction. The groundwork for this thesis began when I read Welsh’s Trainspotting while studying at the University of Edinburgh in Scotland during the spring of 2011.1 wanted to explore why Welsh’s working-class representations felt so similar to the Southern fiction I read at the University of Mississippi, …
Mechanism Of Action Of A Novel Antifungal Compound, Amber Ward
Mechanism Of Action Of A Novel Antifungal Compound, Amber Ward
Honors Theses
Opportunistic fungal infections have become problematic in recent years. There has been an emergence of new fungal pathogens, development of antifungal resistance, and increasing prevalence. In addition, toxicity, resistance, and lack of efficacy as a single agent limit the effectiveness of current antifungal drugs. Therefore, new drugs targeting new pathways are greatly needed. An analog derived from the marine natural product phloeodictine, analog PHL5-34A, was identified as having strong in vitro antifungal activity. In this study, its mechanism of action (MOA) was investigated in the model yeast, Saccharomyces cerevisiae. This study made use of a collection of 166 yeast mutants …
Working Towards A Solution To The Obesity Epidemic: A Marketer's Perspective, Elizabeth Ann Clippard
Working Towards A Solution To The Obesity Epidemic: A Marketer's Perspective, Elizabeth Ann Clippard
Honors Theses
The obesity epidemic is a social issue in that critics are quick to blame business and government for failing the consumers. The truth is that all three parties have failed each other by allowing such a cultural change to occur. The issue is similar to the tobacco public health crisis following the spike in lung cancer in the 1950s and 60s. The tobacco companies were blamed entirely for their unhealthy products and the government still spends millions today regulating their products. In order to improve upon this course of action, I believe that a more cooperative solution exists in order …
Angiotensin Ii As A Potential Regulator Of Inflammatory Cytokines In Inducing Hypertension In Systemic Lupus Erythematosus, Khush Singh Aujla
Angiotensin Ii As A Potential Regulator Of Inflammatory Cytokines In Inducing Hypertension In Systemic Lupus Erythematosus, Khush Singh Aujla
Honors Theses
The disease Systemic Lupus Erythematosus is a chronic inflammatory, autoimmune disorder that primarily affects women during their reproductive years. Women with SLE are at a greater risk of developing hypertension, which increases their risk of mortality from a cardiac related event. A proposed mechanism for SLE hypertension suggests that inflammation in the kidneys causes renal dysfunction, presumably resulting in less water excretion, increased plasma volume, and thus high blood pressure. This experiment tests the hypothesis that the T-cells from a mouse model of SLE hyper secrete the inflammatory cytokines IL-17, IL-10, and DFN- y, and are more sensitive to the …
An Investigation Of Host Variation In The Host-Parasite Interaction Of Sciurus Carolinensis And Cuterebra Emasculator, Miles Moore Debardeleben
An Investigation Of Host Variation In The Host-Parasite Interaction Of Sciurus Carolinensis And Cuterebra Emasculator, Miles Moore Debardeleben
Honors Theses
Within a population, susceptibility to parasitism may vary. Individuals possessing certain intrinsic or extrinsic traits are often more likely to be parasitized than individuals within that population that do not possess those certain traits. As a result, parasites can have profound effects of the population dynamics of theirs hosts. Much research has been done on the host-parasite interaction of the eastern grey squirrel {Sciurus caroUnensis) and the tree squirrel hot fly {Cuterebra emasculator). However, relatively little research has been done on host susceptibility to this parasite. Knowing that bot flies can lower reproductive success, reduce fitness, and cause death of …

Investigation Of Brown Recluse (Loxosceles Reclusa) And Black Widow (Latrodectus Mactans) Spider-Bite Diagnoses By Medical Professionals Across Three Regions Of Mississippi, Hillary Michelle Howell
Honors Theses
During 4 weeks of the spring of 2011 and 5 weeks of the fall of 2011, interviews were conducted with medical professionals practicing in Mississippi regarding the diagnosis of brown recluse {Loxosceles reclusa) and black widow {Latrodectus mactans) spider bites. During the spring, a total of 19 interviews were held with emergency room physicians and dermatologists practicing in urban and rural, non-medically underserved areas of Mississippi. The participants varied in their location of practice across the 3 regions of Mississippi. During the fall, a total of 5 interviews were conducted with nurse practitioners and one pediatrician practicing in rural, medically …

The Effects Of A Valproate Fatty Acid Prodrug On The Inositol Biosynthetic Pathway, Gina Kang
The Effects Of A Valproate Fatty Acid Prodrug On The Inositol Biosynthetic Pathway, Gina Kang
Honors Theses
Bipolar disorder is characterized by alternating episodes of mania and extreme depression. Compounds such as omega-3 fatty acids and valproate individually treat symptons of bipolar disorder, one of which is elevated inositol levels. Lithium and valproate are known to reduce iniositol levels. The goal of this project is to combine linoleic acid (an omega-3 fatty acid substitute) with valproate and observe the prodrug's effects on the inositol biosynthetic pathway using Saccharomyces cervisiae yeast as the model system. Since inositol is required for growth, the effects of the prodrug on the inositol biosynthetic pathway was determined by comparing its impact on …
Semiotic Analysis Of Andrews University's Official Seal, Debbie-Ann Francis
Semiotic Analysis Of Andrews University's Official Seal, Debbie-Ann Francis
Honors Theses
This essay focuses on the significance of the symbols used within the official seal of Andrews University. The official seal of an institution describes the origins, foundations, and the authority that the institution carries. The analysis focused on these particular sections: "Andrews University," "1874," and the pyramid. A concise analysis was made on the other elements of the seal: the colors blue and gold, Corpus, Mens, Spiritus; and the cross-like structure within the middle of the seal. Past and current university personnel were consulted for interviews and for clarification of material. The results revealed that the official seal of Andrews …
An Evaluation Of Electrical Conductivity As A Practical Tool In Mastitis Detection At Andrews University Dairy, Carrie Mesiar
An Evaluation Of Electrical Conductivity As A Practical Tool In Mastitis Detection At Andrews University Dairy, Carrie Mesiar
Honors Theses
An infection in a cow's udder, also known as mastitis, has been a persistent problem for the U.S. dairy community. Mastitis not only decreases milk production, but also shortens the productive life of dairy cattle and can be fatal if left untreated. Mastitis presents in both subclinical and clinical forms - clinical is easy to diagnose and treat, whereas subclinical cases are much harder to detect as they present no physical symptons, yet can still become clinical in time. At the Andrews University Dairy, part of the milking system includes electrical conductivity (EC) determination which measures the ionic composition of …

Evaluation Of Christian Record Products And Services For The Visually Impaired, Sarah Lee
Honors Theses
Christian Record for the Blind (CRSB) offers free Christian publications and services to all who are legally blind. In order to help CRSB better understand the people they serve and plan how to meet the needs of their users, CRSB conducted a major surbey through Andrews University that evaluated the products, services, and key ministry personnel of CRSB. The qualitative portion of the research was conducted through focus group interviews, which revealed themes of digital media accessibility, website quality, concerns of discrimination, disparities between Canadian and US services, and personal treatment and service of representatives.
Developing An Intracellular Neurobiology Lab Sequence For Use In An Interdisciplinary Neurobiology Course, Aleksandra Kozlova-Harris
Developing An Intracellular Neurobiology Lab Sequence For Use In An Interdisciplinary Neurobiology Course, Aleksandra Kozlova-Harris
Honors Theses
The goal of my research was to evaluate procedures currently used in the Intracellular Leech Lab in order to modify the Neurobiology ZOOL475 Lab to increase the rate of successful intracellular recordings for future Neurobiology students. Two approaches were used: the first was to evaluate the possibility of using a less expensive leech species in order to allow students unlimited attempts at recording from ganglia without budget constraints. The second was to evaluate various raising conditions (water, temperature, and age) to optimize the quality of the leech ganglia. Both approaches provided useful information to improve lab success.
The Effects Of Chloro Linoleate Acylal Prodrugs On The Inositol Biosynthetic Pathway In Saccharomyces Cerevisiae, Steffie-Ann Dujon
The Effects Of Chloro Linoleate Acylal Prodrugs On The Inositol Biosynthetic Pathway In Saccharomyces Cerevisiae, Steffie-Ann Dujon
Honors Theses
Bipolar disorder is a debilitating mental illness characterized by recurrent episodes of mania and depression. FDA-approved drugs lithium and valproate, are the most common treatments for this disorder. Currently, omega-3 fatty acids are being researched as an alternative treatment, free of the negative side effects valproate and lithium exhibit. The mechanisms by which valproate and lithium work are unclear, however they effectively lower intracellular inositol levels. Valproate and omega-3 fatty acids similarly inhibit yeast cell growth as well as protein kinase C activity. We hypothesize that omega-3 fatty acids can also decrease inositol levels. A prodrug combining structural properties of …
Ataraxia: A Modern Platonic Utopia, Jeremy Burton
Ataraxia: A Modern Platonic Utopia, Jeremy Burton
Honors Theses
My research focuses on the effects on children raised according to the guidelines for training the Guardians of the ideal society described in Plato's Republic. I explore this concept creatively in a fictional modern Utopian community like that of B. F. Skinner's Walden Two and support this with firsthand accounts of the attempts to make Skinner's work a reality. Combined with a perspective on education in Plato along with the Hitler Youth program, this framework allows me to analyze how we use ideals and philosophy to justify our actions, and ultimately how human nature confounds our attempts to build paradise.
Mating Patterns And Breeding Success In The Larus Glaucescens-Occidentalis Complex, Protection Island, Washington, Andre E. Moncrieff
Mating Patterns And Breeding Success In The Larus Glaucescens-Occidentalis Complex, Protection Island, Washington, Andre E. Moncrieff
Honors Theses
Glaucous-winged gulls (Larus glaucescens) and Western gulls (Larus occidentalis) are found along the Pacific Coast. Where their breeding ranges overlap in Oregon and Washington they hybridize, producing a continuum of phenotypic variation. Whereas most colonies containing these hybrids are found on islands along the coast, several, including a large colony on Protection Island National Wildlife Refuge, WA, are located in the Salish Sea. In 2010 I scored the henotypes of 81 gull pairs at the Protection Island cology using an index based on plumage melanism and bare-part coloration. Gulls from the entire range of phenotypes in the L. glaucescens-occidentalis complex, …
The Design And Creation Of A Portable Water Purification System, Adam Shull
The Design And Creation Of A Portable Water Purification System, Adam Shull
Honors Theses
A portable, low-power water purification system was developed for use by aid workers in underdeveloped world regions. The design included activated carbon and ceramic candle filtration to 0.2 microns for bacteria and turbidity reduction followed by UV irradiation for virus destruction. Flexibility and modularity were incorporated into the system with AC, DC, and environmental power supply options as well as the facility to purify water from either surface or local utility sources. Initial prototype testing indicated the successful filtration of methylene blue dye to well above the 75% UV transmittance level required for virus destruction by the UV reactor.
