Development Of Filial Obligation In Young Adults: An Examination Of Crisis And Lifespan Theory, Rachel Bassett Jan 2019

Development Of Filial Obligation In Young Adults: An Examination Of Crisis And Lifespan Theory, Rachel Bassett

Electronic Theses and Dissertations

Formal care institutions are unable to meet care demands. As a result, informal caregivers (friends, family, neighbors) are called upon to fulfill this need. Adult children make up the majority of these informal caregivers. Adult children vary with respect to whether or not they provide care, and the amount of care provided. Filial obligation and attachment are positive predictors of these care behaviors. A better understanding of how these factors emerge and invoke caregiving behaviors is crucial. The primary hypothesis of this study was that anxiety attachment dimension score would positively relate to baseline filial obligation, and that avoid attachment …

Hadwiger Numbers And Gallai-Ramsey Numbers Of Special Graphs, Christian Bosse Jan 2019

Hadwiger Numbers And Gallai-Ramsey Numbers Of Special Graphs, Christian Bosse

Electronic Theses and Dissertations

This dissertation explores two separate topics on graphs. We first study a far-reaching generalization of the Four Color Theorem. Given a graph G, we use chi(G) to denote the chromatic number; alpha(G) the independence number; and h(G) the Hadwiger number, which is the largest integer t such that the complete graph K_t can be obtained from a subgraph of G by contracting edges. Hadwiger's conjecture from 1943 states that for every graph G, h(G) is greater than or equal to chi(G). This is perhaps the most famous conjecture in Graph Theory and remains open even for graphs G with alpha(G) …

Ab Toxins: Recovery From Intoxication And Relative Potencies, Patrick Cherubin Jan 2019

Ab Toxins: Recovery From Intoxication And Relative Potencies, Patrick Cherubin

Electronic Theses and Dissertations

AB-type protein toxins have a catalytic A subunit attached to a cell-binding B subunit. Ricin, Shiga toxin (Stx), exotoxin A, and diphtheria toxin are AB toxins that act within the host cytosol and kill the host cell through pathways involving the inhibition of protein synthesis. Our overall goal is to help elucidate the cellular basis of intoxication for therapeutic development. According to the current model of intoxication, the effect of AB toxins is irreversible. To test this model, we developed a system that uses flow cytometry and a fluorescent reporter to examine the cellular potency of toxins that inhibit protein …

Bridging The Gap Between Hospital And School: Addressing The Academic And Social-Emotional Needs Of Students With Chronic Illness, Nicole Eggert Jan 2019

Bridging The Gap Between Hospital And School: Addressing The Academic And Social-Emotional Needs Of Students With Chronic Illness, Nicole Eggert

Electronic Theses and Dissertations

This dissertation in practice examined the literature and a sample of existing programs that addressed the educational and social-emotional challenges of students with chronic illness in order to bridge the gap between hospital discharge and school re-entry. Literature showed that the hospital homebound setting was problematic for chronically ill students due to minimal hours of academic instruction and little interaction with peers. Students with chronic illness were at higher risk for maladaptive behaviors, lower educational attainment, and higher use of social services. Programs created at other facilities to address this problem were visited and reviewed for pertinent information such as …

Bone Morphogenetic Protein 7 Inhibits Pyroptotic Cell Death In Vascular Smooth Muscle Cells Of Atherosclerotic Apolipoprotein E -/- Mice, Kaley Garner

Electronic Theses and Dissertations

Atherosclerosis (ATH) is an inflammation-mediated disease in which cell death underlies the formation of lesions along the intima layer of vascular walls resulting in vessel narrowing, decreased blood flow, and increased risk of lesion rupture leading to myocardial infarction and stroke. The current study was undertaken to investigate whether inflammation in ATH can induce pyroptosis in vascular smooth muscle cells (SMC's). We therefore hypothesized that pyroptosis occurs and is inhibited by bone morphogenetic protein 7 (BMP7). We examined SMC pyroptosis at acute (D5) and midstage (D28) following disturbed flow-induced hemodynamic injury to the vascular wall using our partial left carotid …

The Wonder Women: Understanding Feminism In Cosplay Performance, Amber Grissom

Electronic Theses and Dissertations

Feminism conjures divisive and at times conflicting thoughts and feelings in the current political climate in the United States. For some, Wonder Woman is a feminist icon, for her devotion to truth, justice, and equality. In recent years, Wonder Woman has become successful in the film industry, and this is reflected by the growing community of cosplayers at comic book conventions. In this study, I examine gender performativity, gender identity, and feminism from the perspective of cosplayers of Wonder Woman. I collected ethnographic data using participant observation and semi-structured interviews with cosplayers at comic book conventions in Florida, Georgia, and …

Understanding Sediment Biogeochemistry And The Role Of Juvenile Oysters On Recently Restored Eastern Oyster Reefs, Bryan Locher Jan 2019

Understanding Sediment Biogeochemistry And The Role Of Juvenile Oysters On Recently Restored Eastern Oyster Reefs, Bryan Locher

Electronic Theses and Dissertations

In recent decades, goals for the restoration of eastern oyster (Crassostrea virginica) populations along the eastern coast of the United States have shifted from increasing harvestable oyster fisheries to enhancing the range of ecosystem services provided by oyster reefs. By filtering large volumes of water and releasing nutrient-rich feces and pseudofeces, oysters can locally enhance sediment biogeochemical cycling compared to that of unstructured benthic environments. An ongoing restoration program in Mosquito Lagoon, FL was leveraged to assess the immediate impacts ( < 1 year) of restoration on sediment biogeochemical properties of oyster reefs. The first study measured both short-term and long-term pools of carbon, nitrogen and phosphorus on dead, natural and restored reefs periodically over one year. The second study investigated one of the contributions to sediment nutrient pools by comparing feeding and feces/pseudofeces nutrient content of juvenile and older oysters. Results show that inorganic nitrogen and phosphorus pools can change within weeks after restoration and total nutrient pools by 6 months post-restoration. Restored reefs experienced a 136 % increase in ammonium, 78 % increase in total nitrogen, 46 % increase in total phosphorus, and 75 % increase in organic matter concentrations after 12 months of restoration. These nutrient increases were all positively correlated with oyster density, shell length and reef height measured on each reef. When standardized to grams of dry tissue weight, juvenile oysters showed significantly higher rates of chlorophyll-a removal, release of ammonium, and biodeposits with higher concentrations of dissolved organic carbon, nitrite + nitrate, and ammonium. The short-term changes to biogeochemical cycling on eastern oyster reefs within the first year of restoration are important to managers seeking to monitor ecosystem service recovery and overall coastal ecosystem health.

Habituation Trajectory During Exposure Therapy: Comparing Trauma Frequency And Trauma Type, Madeline Marks Jan 2019

Habituation Trajectory During Exposure Therapy: Comparing Trauma Frequency And Trauma Type, Madeline Marks

Electronic Theses and Dissertations

The current DSM-5 criteria for Posttraumatic Stress Disorder (PTSD) affords heterogeneous symptom presentations; however, current treatment fails to consider differences in trauma frequency and trauma type. These different symptom profiles that exist within the PTSD framework lead to questions about the generalizability of treatment outcomes from one group to another group. One group of interest is those that experience multiple traumatic events and report multiple index traumas (trauma frequency). The second group of interest is those with a PTSD diagnosis from occupational exposure to traumatic events (trauma type). Appreciation of the reinforcement schedule may be particularly crucial for understanding treatment …

Pooling Correlation Matrices Corrected For Selection Bias: Implications For Meta-Analysis, Kenneth Matthews Jan 2019

Pooling Correlation Matrices Corrected For Selection Bias: Implications For Meta-Analysis, Kenneth Matthews

Electronic Theses and Dissertations

Selection effects systematically attenuate correlations and must be considered when performing meta-analyses. No research domain is immune to selection effects, evident whenever self-selection or attrition take place. In educational research, selection effects are unavoidable in studies of postsecondary admissions, placement testing, or teacher selection. While methods to correct for selection bias are well documented for univariate meta-analyses, they have gone unexamined in multivariate meta-analyses, which synthesize more than one correlation from each study (i.e., a correlation matrix). Multivariate meta-analyses of correlations provide opportunities to explore complex relationships and correcting for selection effects improves the summary effect estimates. I used Monte …

How Do After-School Staff Use Social Networks To Support At-Risk Youth? A Social Capital Analysis, Katherine Philp

Electronic Theses and Dissertations

Little is known about the social capital of adults in after-school settings or the ways in which they use social contacts to support youth success, particularly for at-risk youth. Their effectiveness as brokers for learning opportunities may depend on aspects of their social capital: both the quantity and quality of their social networks as well as their attitudes and beliefs related to seeking help from social contacts. This mixed-methods study surveyed 50 after-school program staff serving teens in high-poverty neighborhoods to examine the characteristics of adult social capital and to explore attitudes towards mobilizing social resources to support youth.

The Schrödinger Equation With Coulomb Potential Admits No Exact Solutions, Ilia Toli Jan 2019

The Schrödinger Equation With Coulomb Potential Admits No Exact Solutions, Ilia Toli

Electronic Theses and Dissertations

We prove that the Schrödinger equation with the electrostatic potential energy expressed by the Coulomb potential does not admit exact solutions for three or more bodies. It follows that the exact solutions proposed by Fock [1–3] are flawed. The Coulomb potential is the problem. Based on the classical (non-quantum) principle of superposition, the Coulomb potential of a system of many particles is assumed to be the sum of all the pairwise Coulomb potentials. We prove that this is not accurate. The Coulomb potential being a hyperbolic (not linear) function, the superposition principle does not apply. The Schrödinger equation as studied …

Fashioning Society: The Use Of Facial Adornments For Social Identification In Late Postclassic Tlaxcallan, Mexico, Angelica Costa

Electronic Theses and Dissertations

In pre-Hispanic Central Mexico, communities frequently practiced various forms of embodying social identity through the use of facial adornments. Ornaments were placed in the ears, nose, and lips to materialize aspects of both self and collective identity. Important characteristics, such as age, gender, status, kinship, and ethnicity can be better understood through analysis of facial ornaments recovered from archaeological sites. Recent research at the Late Postclassic (AD 1420-1521) city of Tlaxcallan has provided insight into how facial ornamentation varied within the central highlands of Mexico. Typological analysis of ornaments and figurines recovered at Tlaxcallan and comparative examinations between Tlaxcalteca and …
