Juvenile Green Turtle (Chelonia Mydas) Foraging Ecology:Feeding Selectivity And Forage Nutrient Analysis, Eliza Gilbert

Electronic Theses and Dissertations

For the endangered green turtle, Chelonia mydas, a fundamental component of recovery and conservation is an understanding of its foraging ecology. Foraging optimality models suggest animals will select resources of high quality over those of low quality. For green turtles, this behavior is important, as sufficient quantities of nutritionally adequate forage items are necessary for growth and reproduction. One intrinsic element in the understanding of green turtle foraging ecology is to identify and document the availability and quality of forage resources preferred by green turtles. The objectives of this study were: 1) determine whether juvenile green turtles showed a feeding …

Kidney Development In Eleutherodactylus Coqui With Relation To Edema Syndrome, Seung Yun Lee

Electronic Theses and Dissertations

Vertebrates develop embryonic kidneys before the final adult kidney. Particularly for organisms with aquatic larvae such as frogs, the first embryonic kidney, the pronephros is essential for the larvae's survival. Those larvae with defective or without pronephroi exhibited pronounced edema. Edema is severe swelling of a body part as a result of fluid retention. To date, although the embryonic kidneys have been extensively studied in various model organisms, it has not been studied in Eleutherodactylus coqui. E. coqui is a direct developing frog and lacks a tadpole phase in its life cycle. I examined the kidney development in E. coqui …

Expresson Of The Endodermal Marker, Ecsox17, During Embryogenesis Of The Direct Developing Frog, Eleutherodactylus Coqui, Srikanth Singamsetty

Electronic Theses and Dissertations

In the model amphibian, Xenopus laevis, the HMG box transcription factor, Sox17, is expressed throughout the vegetal region that forms the endoderm. It is both necessary and sufficient for the endoderm formation. In order to study endoderm formation in the direct developing frog, Eleutherodactylus coqui, its Sox17 orthologue EcSox17 was cloned by Sean Willamson. To look at the expression of EcSox17, I designed primers and did RT-PCR on whole embryos. EcSox17 was expressed from cleavage to hatching of free-living froglet. EcSox17 RNA was present in the ovaries, an expression which has not been reported in any other vertebrate. Whole mount …

This work aims to evaluate the success of UNHCR's initiative to sponsor the repatriation and reintegration of political refugees who voluntarily chose to return to their homeland. The study of political refugees is essential in International Relations, since it entails the failure of preventing ethnic violence and civil unrest. Overall, the emergence of refugees is the product of the inability of conflict prevention. Voluntary repatriation and reintegration of these refugees provides a message of mending relations, …

The Effects Of Exposure To Feminist Ideology On Women's Body Image, Rachel Diane Peterson

Electronic Theses and Dissertations

Body image disturbance has become an increasing problem among women (Cash & Henry, 1995). Thus researchers have begun to focus on methods of prevention and intervention. Programs utilizing psychoeducation and Festinger's cognitive dissonance theory, for example, have been found to reduce body image dissatisfaction and related symptomatology. The information provided and potential impact are limited, however, because the interventions do not offer women an adaptive method of interpreting the many appearance-related messages they experience. This study sought to determine if exposure to feminist theory of body image may act as a buffer – a filter through which cultural messages about …

Couple Play As A Predictor Of Couple Bonding, Physical Health And Emotional Health, Linda Vanderbleek

Electronic Theses and Dissertations

Traditional couple counseling research focused on why people end relationships, with research only recently addressing what factors contribute to relationship satisfaction and stability. Yet, throughout this research, minimal attention has been paid to the role of play in couple counseling. The research available on play in couple counseling had varied definitions of couple play and was not based on current couple counseling theory. The research and anecdotal data on couple play proposed a strong relationship between couple play and the factors that predict successful, long-term couple relationships, individual physical health and emotional health. This study applied current couple counseling theory …

Cascading Effects Of Predator Removal On The Ecology Of Sea Turtle Nesting Beaches, Brandon Barton

Electronic Theses and Dissertations

Traditional views of food web dynamics have characterized species interactions as linear and direct. However, modern food web theory suggests that interactions can also be nonlinear and indirect, so that disturbance at one trophic level is transmitted throughout the community. Many previous studies have demonstrated that the removal of top predators from terrestrial ecosystems can have broad-scale impacts on community ecology. I examined the direct and indirect effects of raccoon removal from sea turtle nesting beaches in east-central Florida during the summers of 2003 and 2004. Raccoon and ghost crab predation are among the highest causes of egg mortality for …

Constructing Educational Criticism Of Online Courses: A Model For Implementation By Practitioners, Kelvin Thompson

Electronic Theses and Dissertations

Online courses are complex, human-driven contexts for formal learning. Little has been said about the environment emerging from the interaction of instructor(s), learners, and other resources in such courses. Theories that focus on instructional settings and methods that are designed to accommodate inquiry into complex phenomena are essential to the systematic study of online courses. Such a line of research is necessary as the basis for a common language with which we can begin to speak holistically about online courses. In this dissertation, I attempt to generate better questions about the nature of online instructional environments. By combining prior works …

Resource Allocation Using Touch And Audition, David Mortimer

Electronic Theses and Dissertations

When people multi-task with inputs that demand attention, processing, andencoding, sensory interference is possible at almost any level. Multiple Resource Theory (MRT) suggests that such interference may be avoided by drawing from separate pools of resources available when using different sensory channels, memory processes, and even different response modes. Thus, there should be advantages in dividing tasks among different sensory channels to tap independent pools of attentional resources. For example, people are better with two tasks using the eye and ear, than when using two auditory or two visual inputs. The majority of the research on MRT involves visual to …

Missing data is very common in survey research. However, currently few guidelines exist with regard to the diagnosis and remedy to missing data in survey research. The goal of this thesis was to investigate properties and effects of three selected missing data techniques (listwise deletion, hot deck imputation, and multiple imputation) via a simulation study, and apply the three methods to address the missing race problem in a real data set extracted from teh National Hospital Discharge Survey. The results of this study showed that multiple imputation and hot deck imputation procedures provided more reliable parameter estimates than did listwise …

Examining Multisystem Coordination In Response To Stressors In Early Childhood, Tiffany Phu

Electronic Theses and Dissertations

This dissertation presents a set of two studies that investigate linkages between the Hypothalamic-Pituitary-Adrenal (HPA) axis and Sympathetic Nervous System (SNS) in response to a stressor paradigm among young children experiencing low-income. Contextual/child factors that shape multisystem physiologic coordination were also examined. A novel application of structural equation modeling was used to model sample-by-sample linkages between salivary analytes that indexed HPA axis and SNS functioning (respectively, salivary cortisol and salivary alpha amylase [sAA]). The preschoolers in Study 1 showed linkages between salivary cortisol and sAA across a novel research visit at their childcare center that included a stressor paradigm. Child …

West African Food Traditions In Virginia Foodways: A Historical Analysis Of Origins And Survivals., Lisa R. Shiflett

Electronic Theses and Dissertations

The degree of African cultural survivals in African-American culture has been debated since the Civil War. Convincing research that West African cultural traits did survive in African-American culture, particularly in African-Amercian foodways, focuses on the lower south, neglecting the upper south. This thesis fills that gap by identifying West African traits in African-as well as Anglo-America foodways in Virginia, focusing on four broad research areas: Native American and Anglo-American foodways during the colonial and early Republic eras; West African foodways; African-American foodways during slavery; and current trends in Virginia foodways. Primary sources consulted for this study included archaeological reports, eighteenth …

Characterization Of A Catechol-Type Siderophore And The Detection Of A Possible Outer Membrane Receptor Protein From Rhizobium Leguminosarum Strain Iari 312., Brianne Lee Clark

Electronic Theses and Dissertations

Many gram-negative bacteria produce and secrete siderophores under iron-deficient conditions. Siderophores are low molecular weight compounds (600-1500 Daltons), which chelate ferric iron with an extremely high affinity, and the complex is actively transported across the outer and inner membranes of gram-negative bacteria. There are two main classes of siderophores: catechol and hydroxamate. Catechol-type siderophores chelate ferric iron via hydroxyl groups, and hydroxamate-type siderophores chelate ferric iron via a carbonyl group with an adjacent nitrogen. Rhizobia fix atmospheric nitrogen symbiotically in leguminous plants using the iron-containing enzyme nitrogenase. To satisfy their iron requirements, many rhizobia are known to produce siderophores. Rhizobium …

Non-Specific Stress Indicators And Growth Efficiency In The Archaic And Mississippian At The Perry Site (1 Lu25) In Northwestern Alabama, Robin Wiebe

Electronic Theses and Dissertations

Porotic hyperostosis, linear enamel hypoplasias and adult stature are all nonspecific indicators of stress. When studied together, they provide an understanding of the long-term survival of periods of stress occurring in varying stages of the life of an individual. Because the Perry Site contains both Archaic and Mississippian components, it provides a unique opportunity to examine not only how these indicators interact, but also how interactions may change across time and subsistence base. Most studies show increases in frequency of porotic hyperostosis and linear enamel hypoplasias and a decrease in adult stature with a shift to agriculture. The Perry material …

Dhea Action Is Mediated By Multiple Receptors And Metabolites., Kristy K. Michael Miller

Electronic Theses and Dissertations

Dehydroepiandrosterone (DHEA) is a C-19 adrenal steroid and the most abundant circulating hormone in humans. Since circulating levels decline in late adulthood, treatment of humans with DHEA has been suggested to have beneficial health effects. Although the mechanism of action is unknown, DHEA may be metabolized to active metabolites that exert their physiological effects by receptor-mediated processes and cell signaling pathways. The purpose of this study was to investigate the mechanistic processes of DHEA action. Since DHEA may exert its pleotropic effects by being metabolized to biologically active species, a GC/MS method was developed to quantify the liver microsomal metabolism …

Frequency Of Rad Diagnosis And Attachment Disorder In Community Mental Health Agency Clients., Paula S. Morgan 1958-

Electronic Theses and Dissertations

Attachment Disorder (AD) in children has been characterized by particularly alarming behaviors, yet the identification of this disorder for clinicians in community mental health agencies is problematic. The only available diagnosis that addresses attachment problems is the DSM-IV diagnosis of Reactive Attachment Disorder (RAD), a diagnosis that does not include the more severely disturbed behaviors that have been associated with attachment-disordered children. This dissertation examined the frequency with which CMHA child clients were diagnosed with RAD, as well as the actual occurrence of attachment problems and Attachment Disorder as measured by the Randolph Attachment Disorder Questionnaire (RADA). The Personality Inventory …
