The Efficacy Of Treating Adolescent Depression With Interpersonal Psychotherapy For Adolescents(Ipt-A) In The School Setting, Steven Pasquinelli

Electronic Theses and Dissertations

Depression affects the lives of an estimated 2 to 8% of adolescents in the United States. This disturbance of mood impacts many facets of the individual's life, including the ability to participate in and benefit from educational experiences. School psychologists are challenged to find effective treatments for adolescents experiencing depression that can be delivered in a school setting. Interpersonal Psychotherapy for Adolescents (IPT-A; Mufson, Dorta, Moreau, & Weissman, 2004) has been found effective for adolescents in clinical settings as well as in urban, school-based clinics. Its use as an efficacious treatment with adolescent students in a traditional public school setting …


An Examination Of Racial Differences In Anxiety Disorder Symptom Structure And Trajectories Among Pre-Adolescent Female Youth, Cynthia Altman Jan 2009

An Examination Of Racial Differences In Anxiety Disorder Symptom Structure And Trajectories Among Pre-Adolescent Female Youth, Cynthia Altman

Electronic Theses and Dissertations

Although the experience of anxiety among children and adolescents is well documented in the literature, relatively little empirical study has focused on this topic. Existing research is essentially void of studies into gender-specific aspects of anxiety development and maintenance or race-based differences in anxiety symptomatology. The current study sought to fill this gap by examining racial differences in anxiety disorder symptom structure and trajectories among pre-adolescent female youth. Symptom structure was examined among a sample of 570 girls (252 European American, 318 African American) who completed the Screen for Child Anxiety Related Emotional Disorders (SCARED) at nine years of age …


Engineering The Mosquito Symbiont Pantoea Agglomerans To Secrete Anti-Plasmodium Inhibitory Proteins, Dawn C. Bisi Jan 2009

Engineering The Mosquito Symbiont Pantoea Agglomerans To Secrete Anti-Plasmodium Inhibitory Proteins, Dawn C. Bisi

Electronic Theses and Dissertations

The disease malaria originates from the transmission of the parasite Plasmodium to humans by female anopheline mosquitoes. Estimates put the number of deaths at 1-3 million people annually and this number will increase without the establishment of new control strategies. There is currently no vaccine and the effectiveness of insecticides and drugs are thwarted by the gain of resistances for both the insect and parasite. An alternative genetic engineering approach to combating malaria is presented here. The bacterial mosquito symbiont Pantoea agglomerans, which resides in the mosquito gut, was chosen to express anti-Plasmodium effector gene products that are known to …


Molecular Mechanisms Of Traf6 Ubiquitination And Activation, Zhi Qiang Kent Wang Jan 2009

Molecular Mechanisms Of Traf6 Ubiquitination And Activation, Zhi Qiang Kent Wang

Electronic Theses and Dissertations

The Tumor Necrosis Factor (TNF) Receptor Associated Factor 6 (TRAF6) is an intracellular signal transducers, being responsible for mediating many of the activation events initiated by TNF receptor (TNFR) and Toll-like/Interleukin-1 and 18 receptor (TIR) families, in which TRAF6 plays central roles in numerous biological processes including innate and adaptive immunity, osteoclastogenesis and bone development, CD40 signaling, neuronal cell development, and cancer cell progression.

Acting as an E3 ubiquitin ligase, TRAF6 catalyzes lysine 63 linked poly-ubiquitination of itself and many other signal transducers upon association with upstream effectors possessing a short TRAF Interaction Motif (TIM) peptide sequence in the NF-KappaB …


Near-Infrared Analysis And Process Control Of Pharmaceutical Pelletization Processes, David J. Wargo Jan 2009

Near-Infrared Analysis And Process Control Of Pharmaceutical Pelletization Processes, David J. Wargo

Electronic Theses and Dissertations

This study explored the potential of near-infrared spectroscopy in the determination of pharmaceutical pellet characteristics and to predict desired process endpoints during fluidized bed drug suspension layering and coating operations. Various strengths of diltiazem HCl pellets were prepared via a tangential-spray rotogranulation process and subsequently coated Eudragit RS30D in a Wurster column. In-line and at-line near-IR process monitoring methods were evaluated. Quantitative calibrations for potency, applied polymer solids and dissolution were developed using several different regression models. Both in-line and at-line determinations of pellet potency were effectively accomplished with average standard errors of prediction of 1.11% and 0.63%, respectively. Near-IR …

Influencing T Helper Cell Bias In Autoimmunity, Jonathan Ty Butler Jan 2009

Influencing T Helper Cell Bias In Autoimmunity, Jonathan Ty Butler

MUSC Theses and Dissertations

Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS) that affects approximately 400,000 people in the United States every year and results in neurological deficits. Inflammatory events associated with MS include activation of auto-reactive T cells and migration of these and other immune cells into the CNS, leading to a coordinated attack upon oligodendrocytes and demyelination. Most current therapies only treat the symptoms of disease, not the cause, which is still in large part unknown. Therefore, the identification of the etiology of this complex disease and the development of new therapies is of great importance. Targeting …

Is A Sense Of Inequity An Ancestral Primate Trait? Testing Social Inequity In Cotton Top Tamarins, Julie J. Neiworth, Elizabeth T. Johnson, Katherine Whillock, Julia Greenberg, Vanessa Brown Jan 2009

Is A Sense Of Inequity An Ancestral Primate Trait? Testing Social Inequity In Cotton Top Tamarins, Julie J. Neiworth, Elizabeth T. Johnson, Katherine Whillock, Julia Greenberg, Vanessa Brown

Psychology Faculty Work

To address a controversy in the literature concerning whether monkeys show an aversion to inequity, individuals of a New World monkey species, cotton top tamarins (Saguinus oedipus) were tested in an offering task and in a bartering task. At issue was whether the monkeys rejected rewards because of a violation of expectancy of the preferred reward, or whether they rejected rewards because of a sensitivity to socially mediated inequity. The data from both tasks indicated that the subjects were more likely to reject when preferred rewards were presented, either because of another animal eating the reward (the social condition) or …


Thinking About Me: How Social Awareness Evolved, Julie J. Neiworth Jan 2009

Thinking About Me: How Social Awareness Evolved, Julie J. Neiworth

Psychology Faculty Work

—Humans seem unique in their consideration of others’ goals, motivations, intentions, and needs. But the human form of social awareness did not spring from nowhere; certain mechanisms shared across primates formed the foundation from which these processes derived. A review of recent nonhuman primate research points to particular ancestral mechanisms, including an interest in images moving in synchrony with self, a mirror neuron system that responds in the same way to actions made by the self and by others, and inherited social tolerance that provided the bases for social thinking. Still there is a gap in tracking social awareness from …

Sampling Techniques For Sediment Pore Water In Evaluation Of Reactive Capping Efficacy, Donald E. Wise Jan 2009

Sampling Techniques For Sediment Pore Water In Evaluation Of Reactive Capping Efficacy, Donald E. Wise

Master's Theses and Capstones

Contaminated sediments are a significant problem that has adverse effects on human, animal and plant health. Heavy metal contamination, with dissolved metals being the most bioavailable form, has been occurring since man first started living in communities around water bodies. Pore water provides contaminated metals a medium for transport from the sediment to the water body. Determining the toxic metal concentration in pore water is essential to any remediation plan. In-situ dialysis samplers or peepers were investigated in this thesis as a tool for evaluating metal contamination in sediments. Peeper performance was compared to direct suction samplers. Both samplers were …


The Effect Of Particle-Associated Viruses On Disinfection Processes In Water Treatment, Jessica L. Tokson Jan 2009

The Effect Of Particle-Associated Viruses On Disinfection Processes In Water Treatment, Jessica L. Tokson

Master's Theses and Capstones

This research focused on what accelerates or hinders virus-particle association, how the addition of turbidity affects both chlorine and ultraviolet light disinfection, and if sonication can disrupt virus-particle associations exposing viruses to disinfection methods.

A decrease in pH, from 7--4, was found to accelerate association by 2-logs. Calcium increased association by 2.74-logs, and total organic carbon decreased association by 0.36-logs.

An addition of 5 NTU, the maximum turbidity level allowed by USEPA for unfiltered drinking water supplies, affected both chlorine and UV light disinfection showing differences in the rate of kill per dose. The association of viruses and particles can …

Thermal Exchange Processes Within Shallow Fractured Bedrock: Applications For Standing Column Wells, Sarah B. Mckone Jan 2009

Thermal Exchange Processes Within Shallow Fractured Bedrock: Applications For Standing Column Wells, Sarah B. Mckone

Master's Theses and Capstones

This research investigates thermal properties of fractured bedrock for the purpose of better understanding the sustainability of standing column well (SCW) geothermal heating systems. The three objectives are to quantify effective thermal conductivity and heat capacity of the fracture network; measure heat exchange between the fluid and the fractured surfaces; and estimate time of thermal breakthrough into a pumping well. Single and dipole well tests are performed to meet these objectives. Single well data is compared with an analytical heat flow model to estimate thermal conductivity and heat capacity. Dipole well data is compared to a model of the Kolditz …
