An Assessment Of Athletic Training Educators' Knowledge And Calibration Of Evidence-Based Diagnostic Concepts, Cailee Elizabeth Welch

Human Movement Studies & Special Education Theses & Dissertations

Evidence-based practice (EBP) is a phenomenon that has transitioned into various medical and allied health professions over the past several decades. The purpose of this study was to assess knowledge and calibration levels of evidence-based concepts in athletic training educators, as well as determine the effectiveness of an EBP single-day workshop. All educators attending the 2009 Athletic Training Educators' Conference (N=498) were solicited to participate in this study; 62 male (41.32 ± 8.92) and 79 female (36.08 ± 7.91) responded for a response rate of 28.3% (years of AT teaching experience = 9.81 ± 7.19). A twenty question multiple choice …

Analysis Of Partial Discharge Pulse Height Distribution Parameters, Vinay N. Nimbole

Electrical & Computer Engineering Theses & Dissertations

Partial Discharges (PD) have been traditionally used to assess the state of any insulation system and its remnant life. In earlier work, Perspex (PMMA) samples with a needle plane gap have been aged with AC voltage. Their tree growth was monitored simultaneously by collecting PD at regular intervals of time and taking microphotographs in real time without interrupting the aging voltage. The obtained partial discharge pulse amplitude records were clustered together into groups of class intervals. The sequence of PD pulse height records was quantified as a time series of shape (η), and scale (σ) parameters of a Weibull distribution. …

The Use Of Fourier Transform (Ft) Surface-Enhanced Raman Scattering For Biochemical Analysis, Robert Butler Jeffers

Chemistry & Biochemistry Theses & Dissertations

Surface-enhanced Raman scattering (SERS) is a powerful spectroscopic technique that has created exciting opportunities in the field of bioanalytical chemistry, where it combines ultrasensitive detection of biologically relevant molecules with vibrational spectroscopy. Due to the difficulties in preparing reproducible SERS active substrates, SERS has been mainly used as a qualitative tool. In order for SERS to be utilized as a viable tool for quantitative analysis, simple, facile SERS substrates which generate clean, highly reproducible signals must be developed. This dissertation deals with the evaluation of three different methods of SERS that led to the development of a novel substrate for …

Relationships Between Black Female College Students' Relationships With Their Fathers And Adult Romantic Attachment, Nicole A. Dock

Psychology Theses & Dissertations

The current study examined the relationships between the quality and quantity of time that young Black female college students spent with their fathers during high school as related to romantic attachment and fear of intimacy. Although researchers have investigated the impact that early attachment bonds to mothers have for later psychosocial development, much less research has examined how attachment to fathers may be associated with psychosocial adjustment in young adulthood. In particular, there is a lack of information on how relationships to one's father or father figure may be associated with adjustment in young women from culturally diverse populations.

Changing Fecundity And Reproductive Output In Females Of A Chesapeake Bay Population Of Blue Crab, Callinectes Sapidus, Shannon L. Wells

OES Theses and Dissertations

The Chesapeake Bay blue crab, Callinectes sapidus, is an important species both ecologically and as a fishery. Fishery dependent and independent data indicate that the population declined abruptly in the mid-1990s and has remained low. Previous work prior to the decline in population abundance found a significant relationship between size and fecundity for mature females. As with many heavily fished populations, this population has experienced a reduction in the size at maturity. The objectives of this study were to reassess the fecundity of the population, determine the lipid and protein energy allocated for reproduction, and to examine the concentrations …

Developing A Philosophical Profile Of The Individual For Complex Problem-Solving Through Agent-Based Modeling, Ipek Bozkurt

Engineering Management & Systems Engineering Theses & Dissertations

Research that focuses on the emotional, mental, behavioral and cognitive capabilities of individuals has been abundant within disciplines such as psychology, sociology, and anthropology, among others. The main argument made in this dissertation, however, is that a different perspective is necessary in order to gain insight about individuals when facing the complex problems that are presented within engineering and management disciplines. This is done by developing the Philosophical Profile of the Individual (PPI) that uses epistemology, ontology and teleology as underlying dimensions of philosophical predispositions. The epistemology dimension considers whether an individual is an Empiricist or a Rationalist, the ontology …

An Adaptive Method For Calculating Blow-Up Solutions, Charles F. Touron

Mathematics & Statistics Theses & Dissertations

Reactive-diffusive systems modeling physical phenomena in certain situations develop a singularity at a finite value of the independent variable referred to as "blow-up." The attempt to find the blow-up time analytically is most often impossible, thus requiring a numerical determination of the value. The numerical methods often use a priori knowledge of the blow-up solution such as monotonicity or self-similarity. For equations where such a priori knowledge is unavailable, ad hoc methods were constructed. The object of this research is to develop a simple and consistent approach to find numerically the blow-up solution without having a priori knowledge or resorting …

Inhibition Of Yeast Hexokinase By The Antimalarial Drug Artemisinin: Probing Mechanism Of Action With A Model Enzyme, Jennifer S. Spence

Biological Sciences Theses & Dissertations

A leading infectious cause of death, malaria threatens approximately half of the world's population, and drug-resistant strains of Plasmodium falciparum have created immense difficulty in chemotherapy of the disease. The artemisinin (ART) class of antimalarials may represent a powerful solution. In addition to their safety, effectiveness, and moderate cost, they are the only drugs in use for which there has been no widespread evidence of clinical resistance. The exact parasiticidal mechanism of ART is highly contested, but evidence suggests that protein alkylation may play a role in cytotoxicity. in vitro essays were performed using yeast hexokinase (HK) to demonstrate a …

Lipid Targets Of The Antimalarial Trioxanes In Plasmodium Falciparum, Carmony Leah Hartwig

Biological Sciences Theses & Dissertations

Malaria is among the most debilitating diseases of man. The protozoan parasite, Plasmodium falciparum, causes over a million annual fatalities. The antimalarial trioxanes, exemplified by artemisinin, are among the few pharmaceuticals for which clinical resistance has not become widespread. Artemisinin is a naturally occurring sesquiterpene lactone, containing a unique endoperoxide pharmacophore. Despite extensive study, the precise antimalarial mechanism of action of trioxanes remains elusive. Heme iron-mediated cleavage of the endoperoxide within the parasite digestive vacuole is hypothesized to generate cytotoxic metabolites capable of alkylating heme and damaging cellular macromolecules. The hypothesis of this research is that the endoperoxide pharmacophore …

Transmaturities: Gender Trouble As Tentative Analogue For Maturity Trouble, Diederik F. Janssen

Reconstruction: Studies in Contemporary Culture

[First paragraph]

Recent contributions to queer studies have been marked by what can provisionally be called a turn toward time, specifically time's various normative condensations around issues of community formation, most notably with respect to the family and the subculture. While the specter of time often seems suspended between elite contemplation and public imagination, the emergent rubric of temporalities, explored in GLQ's special issue (2007;13/2-3), announced a possibly radical moment in which genders can be analyzed as breaking down "over time" politically and taxonomically, perhaps to the effect that deconstructive momentum realized in the context of gender/sexuality may facilitate …

Mutating Masculinity: Embodying The Hu(Man) In The Hills Have Eyes, Rebecca Hawkins

Reconstruction: Studies in Contemporary Culture

[First paragraph]

Discussing gender identity in the female warriors of kung fu films, critic Kwai-cheung Lo asks, "Does maleness automatically produce masculinity? Is there a kind of masculinity independent of the biological male? Can the women who kill in action cinema occupy a position that has been historically thought of as exclusively masculine" (138)? In this paper, I am asking similar questions regarding the construction of masculinity in the male victim of a horror film. Since the slasher film genre rose to popularity in the 1970s and 1980s, horror films have often been accused of reveling in voyeuristic misogyny (a …

The Moving Figure: Dialogism In Williams' The Great Figure, Tom Lavazzi

Reconstruction: Studies in Contemporary Culture

[First paragraph]

In recent years, Henry M. Sayre, Christopher J. MacGowan, Barbara M. Fisher, Dickran Tashjian, William Marling, and Peter Halter, among others, have written about the influence of visual artists, especially Marsden Hartley, on Williams' poetry, and, conversely, the influence of Williams' poetry on painting. These critics have variously examined the personal, cultural, aesthetic, and ontological dimensions of the visual arts background of Williams' poetry, including "The Great Figure," first published as the final poem in Sour Grapes, 1921, and well-known as the source for Charles Demuth's 1928 painting, The Figure Five in Gold. Especially relevant to …

Forgetting To Re-Member: 'Post-Racial' Amnesia And Racial History, Maisha Wester

Reconstruction: Studies in Contemporary Culture

[First paragraph]

On a recent trip to New Orleans, LA, I visited three notable sites in the city's history: the infamous slave exchange, now the site of the Omni Hotel and its attached restaurant; Congo Square, now the site of Louis Armstrong Park; and the Lower Ninth Ward, still devastated four years after the near miss of Hurricane Katrina [1]. The former two are marked by diminutive plaques noting the historical relevance of the location even as fabulous new buildings and modernist ornamentation overwhelm the site and its sense of significance. In the case of the later, however, there are …

"Adoption Will Determine The Worthiest Successor": Roman Imperial Adoption, Stephen C. Hebert

History Theses & Dissertations

This thesis examines the process by which successors to the Roman Principate were chosen under the Julio-Claudians, Flavians, and Antonine dynasties. Rome extended its hegemony over the Mediterranean and Europe with citizen-farmer legionaries who were loyal to the senate and Roman state. Warfare necessitated the creation of a professional army in which loyalty shifted from that of the state and senate to their respective military commander. Generals such as Sulla and Caesar used their legions to gain power establishing new political precedence from which future ambitious generals built upon, ultimately leading to the end of the Republic and the birth …

A Three Dimensional Numerical Investigation Of A Donor Material In Friction Stir Welding, Justin M. Rice

Mechanical & Aerospace Engineering Theses & Dissertations

Excessive tool wear generated during the plunge phase of Friction Stir Welding has slowed the pace of expanding the Friction Stir Welding process to hard materials such as steel. This research uses a finite element model of the Johnson-Cook material constitutive law to investigate the shear stresses, axial forces, and temperatures experienced by the tool and the workpiece during the plunge stage of Friction Stir Welding. The model in this research was developed using the commercially available finite element analysis software ABAQUS/Explicit and consists of both a deformable workpiece and a deformable tool. By implementing the concept of using a …
