An Analysis Of The Effect Of Involuntary Mobility On Student Achievement As Measured By The Florida Comprehensive Assessment Test, Mark Willard Mullins

Electronic Theses and Dissertations

This study examined the impact of involuntary mobility on the academic achievement of tenth grade students in a Central Florida school district. Students of involuntary mobility were selected as the result of new attendance boundaries due to new high school construction. Students were compared against non-mobile peers at schools of like demographics (i.e. poverty level and ethnicity). Mobility status (involuntary or no mobility) was the independent variable. The dependent variable, academic achievement, was measured by students’ tenth grade developmental scale scores in reading and mathematics on the Florida Comprehensive Assessment Test. Students’ ninth grade test scores were used as a …

Do Immigrant Students Consume Less Energy Than Native-Born American Students?, Lei Lei

Electronic Theses and Dissertations

This paper uses a sociological model to compare the residential energy consumption between immigrant students and native-born American students and to explain the difference by demographic characteristics, values, and specific attitudes. Further, it tries to explore whether the relationship between immigration status and residential energy consumption is mediated by value orientation towards frugality and specific attitudes towards energy conservation. The data of an online survey among native-born and foreign-born students at the University of Central Florida are used. The results suggest that immigrants consume less energy at home than native-born Americans, but the time stayed in the US doesn’t have …

Exploring Women's Life Course Experiences With Weight Using Story Theory, Poff Allison Edmonds

Electronic Theses and Dissertations

This qualitative study included women who had gone through the menopausal transition and had experienced obesity, and it focused on their weight histories and experiences across the life course. The goal of this research was to add to the body of knowledge concerning weight gain by applying a novel middle range theory (story theory). Story theory was used to collect and interpret from women’s life course stories the critical themes and patterns of their weight gain. Oral accounts were elicited during personal interviews from a convenience sample of ten women recruited from a weight loss and exercise program in Central …

A Proposed Methodology For Predicting The Carbon And Nitrogen Stable Isotope Measures Of K'Inich Yax K'Uk Mo', Copan Dynastic Founder, Keith Edwards

Electronic Theses and Dissertations

The purpose of this thesis is to show that stable isotope analysis can be used to predict K’inich Yax K’uk Mo’s stable isotope measures based on Stuart’s (2007) hypothesis that K’inich Yax K’uk Mo’, the dynastic founder of the Copan royal lineage, was a Caracol lord. There is significant and convincing evidence that K’inich Yak K’uk Mo’ had a non-Copanec origin. Stable isotope analysis is a tested and reliable method for detailing diets and migratory paths of ancient humans and this theory is applied as a predictor of the stable isotope measures of K’inich Yax K’uk Mo’, if he did …

Discriminating Emotions And Engaging Difficult Emotional Material: Implications For Process And Outcome In Written Disclosure, Stephanie L. Nassar

Electronic Theses and Dissertations

Written disclosure participants have experienced numerous psychological and physiological benefits, as compared to those who wrote about neutral topics (Baikie & Wilhelm, 2005; Corter & Petrie, 2011; Frattaroli, 2006; Pennebaker & Chung, in press). Given the beneficial results of expressive writing commonly found among healthy participants, exploration of this method was expanded to broader populations with mixed results. Researchers have attempted to provide a rationale for why, when, and with whom written disclosure works. As emotional clarity and experiential avoidance have been linked to psychological well-being, this study examined their relative contributions to written disclosure benefits. Participants self-reported on measures …

Cross-Validation Of A Recently Published Equation Predicting Energy Expenditure To Run Or Walk A Mile In Normal Weight And Overweight Adults, Cody Edward Morris

Electronic Theses and Dissertations

An equation recently published by Loftin, et al. (2010) was cross-validated using 30 subjects consisting of 10 normal weight walkers, 10 overweight walkers, and 10 distance runners. Gender was balanced across sub-groups. Participants walked or ran for 5 minutes at their preferred pace. Preferred walking pace was determined by six timed 50-ft trials and preferred running pace by the runner's typical training pace. Energy expenditure (EE) was determined via indirect calorimetry and reported in absolute units (kcal), and corrected to a mile distance. Body composition was assessed via DXA. EE per mile was predicted using the Loftin, et al. (2010) …

Biopharmaceutical Approaches For Improved Drug Delivery Across Ocular Barriers, Ketan Hippalgaonkar

Electronic Theses and Dissertations

The eye is protected from the external environment by various physiological and anatomical barriers. These barriers through there protective actions drastically diminish the ocular bioavailability of drugs. The corneal epithelium acts as a major barrier towards the permeation of hydrophilic agents, whereas poor aqueous solubility presents a formulation challenge for lipophilic compounds. Additionally, P-glycoprotein (P-gp) expressed on the retinal pigmented epithelium (RPE P-gp) limits the penetration of substrates, in therapeutically relevant concentrations, into the back-of-the-eye.

In the present research, use of penetration enhancers (chitosan, benzalkonium chloride (BAK) and ethylenediaminetetraacetic acid (EDTA)) and formulation approaches (cyclodextrins and solid lipid nanoparticles (SLNs)) …

The Effects Of Chronic Prophylactic Naproxen Sodium On Skeletal Muscle Adaptation To Resistance Exercise In Recreationally-Trained College-Aged Males, Christi Brewer

Electronic Theses and Dissertations

Resistance exercise causes exercise-induced muscle injury (EIMI), triggering an acute local inflammatory response associated with delayed-onset muscle soreness (DOMS). DOMS is characterized by a predictable discomfort and decreased level of muscle performance and is believed to be the product of both mechanical and inflammatory processes. From the latter perspective, non-steroidal anti-inflammatory drugs (NSAIDs) have been investigated for their potential to alleviate DOMS-associated symptoms. Such analgesics exert their effects by blocking the formation of prostaglandins; however, prostaglandins, specifically prostaglandin F 2?, also play an important role in skeletal muscle regeneration. While some have advocated the use of NSAIDs for the relief …

Running Identities And Interaction Ritual Chains, Jonathan Malonzo Dial

Electronic Theses and Dissertations

This thesis links two theories, Interaction Ritual Chains (IRC) with Identity Control Theory (ICT), through a multi-method study of group training programs for beginning runners. First, group training programs are identified as IRCs. Second, we see that IRCs produce identities within individuals which reflect the IRC's activities and its group members. Third, we look at how IRCs of varied strengths produce identities of varied strengths. Fourth, we compare different types of group training programs and their abilities to develop identities. Finally, we conclude that IRCs are mechanisms which individuals are able to use as part of the self-verification process.

Effect Of Uv-A Irradiance On Lipid Accumulation In Nannochloropsis Oculata, Rathy Srinivas

Electronic Theses and Dissertations

The marine microalgae Nannochloropsis spp. are of both ecological and economic importance as they contribute to the base of the food chain of marine systems, and can accumulate a considerable amount of lipids. Their lipids can be grouped into two categories, storage lipids, which are mainly triglycerides (TGs), and structural lipids, which are composed of polyunsaturated fatty acids (PUFAs). PUFAs are essential nutrients for both aquatic animals and humans, while TGs can be transesterified to produce biodiesel. Lipid formation in microalgae depends on several environmental factors and Nannochloropsis spp. have been shown to accumulate excess storage lipids under stressful conditions. …

Characterization Of Intermolecular Pi-Type Interactions Using Sophisticated Quantum Mechanical, Electronic Structure Computations, Emily Joy Carrell

Electronic Theses and Dissertations

Much like the instrumentation in an experimental lab, computational chemists use computers to solve the mathematical equations that describe the physics of electrons to understand the chemistry involved. The combination of the two main components of computational chemistry, the basis set and method, determines the ``cost'' (disk, memory, and CPU time) of a computation. A variety of basis sets and methods have been developed in the past century. The focus of this report is to accurately describe non-covalent interactions with the use of various quantum computational techniques. In Chapter 1 a brief discussion on the theory behind computational chemistry is …

The Synergies Between Tourism Expansion And Development An Analysis Of Economic Growth, Poverty And Human Development In Ecuador, Manuel Antonio Rivera

Electronic Theses and Dissertations

This dissertation attempts to answer the question of what has been the effect of tourism expansion and development in Ecuador. We attempt to analyze, both theoretically and empirically, the relationship between tourism and development. There have been an enormous number of studies explaining how tourism can affect the various dimensions of development. However, no research has been undertaken to simultaneously empirically examine the impact that changes in tourism expansion has on poverty, human development, and economic growth. To this end, we propose a cointergation methodology with an error correction model to estimate the impact of tourism expansion on poverty, human …

Adherence Practices Of Caucasian Women With Hypertension Residing In Rural Florida An Exploratory Study, Jeanne M. Hopple

Three Essays On Applications Of Intrahousehold Resource Allocation Models, Santikorn Pamornpathomkul

Electronic Theses and Dissertations

This dissertation consists of three chapters on the topic of intrahousehold resource allocation models. The first chapter tests the unitary and general collective models of intrahousehold resource allocation for various household compositions. I find that, for the quasiquadratic Engel curve specification, the overall results support the previous findings in the literature that the unitary model fails to explain how resources are allocated for all household types. However, when using the QUAIDS specification, the results can reject the unitary model only for smaller-sized households. The general collective model, on the other hand, cannot be rejected in either quasi-quadratic or QUAIDS and …

The Effects Of Seasonal Changes And Turbidity On Swimming Performance In White Crappie Pomoxis Annularis And Black Crappie Pomoxis Nigromaculatus., Caleb Joseph Gaston

Electronic Theses and Dissertations

Factors that affect swimming performance in fish can also affect fitness. I tested the effects of time of day, season and turbidity on swimming performance in black crappie Pomoxis nigromaculatus and white crappie Pomoxis annularis. These closely related fish co-occur and their relative abundance is thought to be governed by the levels of turbidity in the form of suspended sediments. Black crappie predominate in clear bodies of water and exhibited significantly greater critical swimming speeds in clear water than did white crappie during spring days and winter nights. A significant reduction in critical swimming speed was observed in black crappie …

The Application Of Two-Photon Absorbing Probes In Lysosomal, Zinc Ion Sensing And Folate Receptor-Targeted Bioimaging, Xuhua Wang

Electronic Theses and Dissertations

Two-photon fluorescence microscopy (2PFM) has become a powerful technique for bioimaging in non-invasive cancer diagnosis and also investigating the mechanization and original of a variety of diseases by tracking various biological processes. Because the fluorescence emission by two photon absorbing (2PA) is directly proportional to the square of the intensity of excitation light, this intrinsic property of 2PA provides 2PFM great advantages over traditional one-photon fluorescence microscopy (1PFM), including high 3D spatial localization, less photodamage and interference from biological tissue because of using longer wavelength excitation (700-1300 nm). However, most 2PA probes are hydrophobic and their photostabilities are questionable, severely …

Guided and influenced by a famous follow-up study in criminology focused on desistance from crime, this dissertation studies desistance from crime, homelessness, and substance abuse. In the early 1990s, The New Orleans Homeless Substance Abusers Project (NOHSAP) was founded as an experiment funded by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) to uncover optimal treatment strategies for homeless alcoholics and drug addicts. The program ran for three years (1991-1993) and in those years, 670 homeless New Orleans men and women were admitted into treatment. Some of the original clients were followed for as long as 18 months, but …

Understanding The Subjectivities Of Pastors And Beliefs About The Current American Church Culture, Michael Ellis Anderson

Electronic Theses and Dissertations

This study investigates the spiritual subjectivities of pastors in the Mainstream White Middle Class Evangelical Church in the context of American capitalism. The Evangelical church carries extreme amounts of power and influence in shaping the beliefs of individuals in American society. However, very little pointed research of pastors' spiritual subjectivities that guide their teachings and views in this sub-sect of church culture is present in academia. Anthropology, along with other disciplines, often focuses on dominant churches from an etic perspective of politics and power relations without fully considering the spiritual beliefs of pastors. This etic perspective can miss the deeply …

Glial Differentiation Of Human Umbilical Stem Cells In 2d And 3d Environments, Hedvika Davis

Electronic Theses and Dissertations

During differentiation stem cells are exposed to a range of microenvironmental chemical and physical cues. In this study, human multipotent progenitor cells (hMLPCs) were differentiated from umbilical cord into oligodendrocytes and astrocytes. Chemical cues were represented by a novel defined differentiation medium containing the neurotransmitter norepinephrine (NE). In traditional 2 dimensional (2D) conditions, the hMLPCs differentiated into oligodendrocyte precursors, but did not progress further. However, in a constructed 3 dimensional (3D) environment, the hMLPCs differentiated into committed oligodendrocytes that expressed MBP. When co-cultured with rat embryonic hippocampal neurons (EHNs), hMLPCs developed in astrocytes or oligodendrocytes, based on presence of growth …

Does Foreign Aid Promote Development? A Study Of The Effects Of Foreign Aid On Development In Sub-Saharan Africa, Rachael J. Gray

Electronic Theses and Dissertations

Foreign aid aims to improve economic conditions and quality of life in developing countries. The literature on the efficacy of foreign aid to date has been inconclusive; yet there is some evidence that institutional factors may condition the relationship between aid and development. This research focuses on the effects of foreign aid on development, taking into consideration the effects of political institutional factors as intervening in the connection between aid and development. Specifically, this study considers the effects of democracy (political rights and civil liberties) and level of corruption on the relationship between aid and development in sub-Saharan Africa. Development …

The Origins Of Lactase Persistence And Ongoing Convergent Evolution, Beth A. Keller

Electronic Theses and Dissertations

As a primary factor in human evolution, natural selection is an important component of genetic research. Studies of lactase persistence suggest that positive selection has played a powerful role in the adaptation to a lifelong consumption of fresh milk. Using multiple research studies of lactase persistence and suspected corresponding single nucleotide genetic polymorphisms, this study combines data sources to determine whether evidence exists for natural selection of a specific cytosine-to-thymine genetic mutation located 13,910 base pairs (T-13910) upstream from the lactase gene. This polymorphism has potential to be a causal element for lactase persistence, and data suggest that natural selection …

The study purpose was to examine whether a difference exists in health outcomes in the open room versus single private room NICU environment. The factors considered were weight gain, ventilator days, hospital length of stay, incidence and grade of intraventricular hemorrhage (IVH), the number of parental visits, and perceptions of maternal stress. Infants hospitalized in …

Neurochemical Levels Correlate With Population Level Differences In Social Structure And Individual Behavior In The Polyphenic Spider, Anelosimus Studiosus., Jennifer Bryson Price

Electronic Theses and Dissertations

Anelosimus studiosus is a socially polyphenic spider. Individuals can be classified as social/tolerant or solitary/aggressive. These behavioral differences are associated with considerable variation in social structure. Here, we begin to examine the physiological differences that may underlie the behavioral dimorphism in this species and possible implications for the evolution of sociality. Octopamine is a neurotransmitter that has been found to elevate aggression in invertebrates. Serotonin has been shown, in some cases, to interact antagonistically with octopamine. We used High Pressure Liquid Chromatography with Electrochemical Detection to quantify levels of these neurochemicals among adult females from social (multi-female) and solitary (single-female) …
