Coarse Root, Forest Litter, And Soil Organic Matter Contributions To Carbon Sequestration In Loblolly Pine (Pinus Taeda) Plantations In East Texas, William Wedge

Electronic Theses and Dissertations

Understanding ecosystem carbon dynamics is of increasing importance with atmospheric carbon dioxide (CO2) concentrations on the rise. Land management strategies, such as land use conversion, effect ecosystem carbon cycling dynamics and can alter the quantity of carbon sequestered in vegetation and soils. In East Texas and much of the southern United States, there has been a trend of converting marginal pastureland into loblolly pine (Pinus taeda) plantations. This afforestation, like all other land use conversions, leads to a redistribution of carbon in vegetation and soil carbon sinks. In 2003, five marginal pasturelands in East Texas were afforested with loblolly pine …

Using The Coaching Approach Behavior And Leading By Modeling (Calm) Program To Examine Attachment And Parental Behaviors In Childhood Anxiety, Seana Bandi

Electronic Theses and Dissertations

Anxiety is one of the most common disorders in children that can often lead to detrimental outcomes. Empirically-supported risk factors for child anxiety include the child’s temperament and behavioral inhibition, insecure attachment, parental over-controlling behaviors, parental anxiety, and the impact of adverse life events on the child. Targeting these risk factors early on has the ability to lead to a decrease in anxiety symptoms later in adolescence and adulthood.

Evidence suggests behavioral, therapeutic interventions are effective for treating anxiety and other mood disorders for middle childhood and adolescents. Recent research has begun to focus on developmentally-appropriate adaptations for younger children …

Score Improvement Comparison From Psat To Sat Between Two Schools, Salvatore Brusco

Electronic Theses and Dissertations

The score a student earns on the PSAT is a predictor for what they earn on the SAT. Based on a student's PSAT score, we construct a Bayesian model to predict, with 95% certainty, what they will earn on their SAT. Furthermore, we explore differences in this prediction between two high schools in the same district; and ask whether the probability of improvement from the PSAT to the SAT is consistent between these two schools.

Mentor As Scaffold: A Mixed-Methods Exploration Of Feminist-Informed Mentoring In The Undergraduate Setting, Elizabeth Bennett

Electronic Theses and Dissertations

There has been little consensus around the definition or meaning of mentoring as a phenomenon. As highlighted first by Jacobi (1991) and more recently by Crisp and Cruz (2009), the relatively small mentoring literature is plagued by a poor understanding of mentoring itself. Additionally, there are few guiding recommendations for the development of formal mentoring programs, particularly those informed by feminist pedagogy and theory, at the undergraduate level. To begin to address these gaps in the mentoring literature, I conducted a mixed-methods study with a convergent parallel design (Creswell & Clark, 2007) and qualitative emphasis. Eight participants completed individual, semi-structured …

A Quantitative Study Of Drug Recrystallization In Drug-In-Adhesive Transdermal Patches Using Vibrational Spectroscopy, Yi Li

Electronic Theses and Dissertations

Drug-in-adhesive (DIA) transdermal patches are an important type of transdermal drug delivery system (TDDS). The drugs used in the DIA system are frequently present in metastable forms, such as amorphous solids or supercooled liquids. These drug states are thermodynamically unstable and tend to undergo recrystallization. Recrystallization of the active pharmaceutical ingredient can adversely affect the efficacy of transdermal products. This dissertation demonstrates a systematic approach to quantify the crystalline content of the API in DIA systems. This approach uses a novel method of preparing calibration standards and a spectroscopic method to reliably predict crystalline content in DIA patches. Spectroscopic tools, …

Impact Baseline Composite Score Differences Among Student Athletes, Kerry Schutte

Electronic Theses and Dissertations

The ImPACT aims to measure neurocognitive functioning in student athletes. Many schools administer preseason ImPACT assessments to determine athletes’ baseline functioning. Follow-up ImPACT assessments are administered to athletes who sustain concussions to compare their pre- and post-injury functioning. Normative data may be used in place of individualized baseline scores if athletes were not administered baseline assessments. At the inception of this study, normative datasets consisted of scores from typically developing athletes. However, research suggests athletes of varying gender and exceptionality statuses perform differently on baseline ImPACT assessments. In particular, differences were found among male and female athletes as well as …

Beyond A Reasonable Doubt: A Discourse Analysis Of Forensic And Psychological Truth In Child Narratives, Elizabeth Samson

Electronic Theses and Dissertations

This dissertation draws on a hermeneutically-informed modification of Potter and Wetherell’s (1987) discourse analysis methodology to explore how child memory and experience are conceptualized in two widely-used forensic psychology training manuals. Current research about child testimony tends to focus on how well children can factually recount their experiences, or on optimizing interviewer performance so as to obtain accurate accounts and minimize the risk of distorting children’s memories. Results of this discourse analysis include: 1) frequent advisement of evaluator caution, objectivity, and thoroughness, since evaluators are understood as responsible for preserving the accuracy of children’s memories during the evaluation process; and …

Unruly Matter: Masculine Consumption In English Restoration Literature, Shawn Watkins

Electronic Theses and Dissertations

Unruly Matter: Masculine Consumption in English Restoration Literature

Over the past several decades, material culture scholars working within the “Long 18^th Century” have identified how the figure of the woman consumer became an ideological nodal point that registered new enthusiasm for emerging economic dynamics (mercantilism, nascent capitalism, etc.) while also expressing masculine anxieties about consumerism and the role of consumable goods in English society. Although many scholars have noted that men functioned symbolically and ideologically as English society’s primary consumers of material goods in the later 17^th century, there is no scholarly work that aims to describe the …

Dual Inhibition Of The Pi3k/Akt And Mek5/Erk5 Pathways For The Treatment Of Breast Cancer, Thomas Douglas Wright

Electronic Theses and Dissertations

Breast cancer is a heterogeneous disease state with several challenging frontiers. In particular, aberrations in the Phosphoinositide-3-kinase (PI3K) and Mitogen Activated Protein Kinase (MAPK) pathways have been linked to increased breast cancer proliferation and survival. It has been proposed that these survival characteristics are enhanced through compensatory signaling and crosstalk mechanisms. New evidence suggests that MEK5/ERK5, a member of the MAPK family, is a crucial component in the proliferation and survival of several aggressive cancers. We hypothesize that inhibiting both PI3K/Akt and MEK5/ERK5 pathways will decrease cell viability while maintaining limited collateral toxicity. In this study, we examined the effects …

Kink In Flux: Bdsm Theory And Sexual Praxis, Celeste Pietrusza

Electronic Theses and Dissertations

The opening decades of the 21^st century have seen a veritable explosion of representations of bondage, discipline and sadomasochism (BDSM) and kink practices in mainstream media and American culture. Along with this, empirical researchers working in sexuality studies continue to show, contrary to the history of stigmatizing accounts in the history of clinical psychology, no evidence of increased pathology and, in some studies, better outcomes on measures of mental health.

Given the legacy of psychoanalysis in foregrounding considerations of sadomasochism and sexuality for the human psyche, it seems particularly well positioned to approach the complexities of dynamic fantasies involved …
