Not Just One Of The Boys: A Post-Feminist Critique Of Title Ix's Vision For Gender Equity In Sports, Dionne L. Koller

All Faculty Scholarship

Title IX as applied to athletics is a high-profile, controversial public policy effort that has opened up the world of athletics to millions of girls and women. Yet as it is both celebrated for the opportunities it has created for women, and decried as going too far at the expense of men, a reality persists that women do not pursue or remain committed to sport in numbers comparable to men. This Article seeks to explore this phenomenon by moving the discourse beyond the debate over whether women are inherently as "interested" in sport as men to examine the conception of …

Does Affective Commitment Decrease The Level Of Stress Reported In Teachers? A Comparison Of Primary And Secondary School Teachers, Rhiannon Williams

The Plymouth Student Scientist

Occupational stress has been established as a predictor of low physical and psychological well-being. Organisational commitment can act as a buffer to the adverse effects of stress. Two types of commitment (affective and continuance) were studied to determine whether they have the same buffering effect. The ASSET questionnaire was completed by 112 teachers (52 primary, 60 secondary). The two types of commitment differed in their effect on stress, with high affective commitment leading to lower levels of stress and high continuance commitment resulting in higher levels of stress. No difference was found between the reported stress levels of primary and …

Online Gaming: Prohibition Vs. Regulation, Andrew Montgomery

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since online gaming began in 1995, the industry has been unsettled. Despite online gaming being viewed as illegal by the United States government, revenues generated from players in the U.S. grew consistently and rapidly from 1995 to 2006. U.S. lawmakers believed they clarified the legality issue by passing the Unlawful Internet Gambling Enforcement Act in 2006 (UIGEA); however, this legislation did little to discourage people in the U.S. from engaging in online gambling. U.S. lawmakers have long debated prohibition vs. regulation of the industry. Given the apparent ineffectiveness of online gaming prohibition via UIGEA, lawmakers favoring legalization and regulation of …

Altering Explicit And Implicit Racial Prejudice Towards African American Males, Veronica A. Glover

UNLV Theses, Dissertations, Professional Papers, and Capstones

Researchers tested 281 undergraduates to determine if positive behavior messages about African American males presented during a learning task affected scores on explicit and implicit racial prejudice measures. During the learning task, we manipulated how many positive messages the participant viewed (100 vs. 150 or none) and the amount of African American males these messages applied to (1 vs. 3). Participants who viewed 150 positive messages about one African American male displayed more explicit prejudice than participants in control groups or participants learning 100 messages about one person. Results for the implicit measure indicated that participants who learned about three …

Characterization And Analysis Techniques Of A Dynamic In Vitro Blood-Brain Barrier Model, Ryan Everett Woodhouse

Biomedical Engineering

The blood-brain barrier (BBB) is responsible for maintaining the sensitive environment required by the brain. Although the BBB is necessary for proper functioning of the brain, it acts as an obstacle for doctors attempting to treat neurological disease. For a drug to act upon the brain, it must first pass through the discriminating BBB. For this reason, much research has been performed in recent years in order to create an in vitro model of the BBB on which drugs targeted for the central nervous system may be tested. The main goal of this project is to create an in vitro …

Neural Coding Of Temporal Information And Its Topography In The Auditory Cortex, Thomas A. Terleph, Raphael Pinaud

Estimation Of Mechanical Properties Of Soft Tissue Subjected To Dynamic Impact, Mohamed R. S. Amar

Department of Industrial and Management Systems Engineering: Dissertations, Theses, and Student Research

This study attempted to estimate the damping properties of human tissue by using spring and damper system as a model. Data of impacting human tissue at the deltoid area was used to obtain a continuous, second order system to represent the mass-spring-damper system. A discrete ARMA(2,1) model was fitted using the data obtained from experiments in which the deceleration of a pendulum impacting human shoulders in the area of the deltoid muscle was measured. The data of the deceleration was integrated twice to obtain estimates of displacement. The integration was done until the maximum displacement occurred at zero velocity.

Improved Mobile Wireless In Vivo Surgical Robots: Modular Design, Experimental Results, And Analysis, Jeff Hawks

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Laparoscopic surgery results in superior patient outcomes as measured by less painful recovery and an earlier return to functional health compared to conventional open surgery. However, the difficulty of manipulating laparoscopic tools from outside the patient’s body generally limits these benefits to patients undergoing relatively simple procedures. The use of miniature in vivo robots that fit entirely inside the peritoneal cavity represents a novel approach to laparoscopic surgery. These robots enable more complex laparoscopic procedures, increasing the number of patients that benefit from laparoscopic surgery.

This thesis describes recent work focused on developing a modular wireless mobile platform that can …

The Effects Of Action, Normality, And Decision Carefulness On Anticipated Regret: Evidence For A Broad Mediating Role Of Decision Justifiability., Jochen Reb, Terry Connolly

Research Collection Lee Kong Chian School Of Business

Two distinct theoretical views explain the effects of action/inaction and social normality on anticipated regret. Norm theory (Kahneman & Miller, 1986) emphasises the role of decision mutability, the ease with which one can imagine having made a different choice. Decision justification theory (Connolly & Zeelenberg, 2002) highlights the role of decision justifiability, the perception that the choice was made on a defensible basis, supported by convincing arguments or using a thoughtful, comprehensive decision process. The present paper tests several contrasting predictions from the two theoretical approaches in a series of four studies. Study 1 replicated earlier findings showing greater anticipated …

Systematics And Molecular Phylogeny Of Two African Stem Borer Genera, Sciomesa Tams & Bowden And Carelis Bowden (Lepidoptera: Noctuidae), P. Moyal, B. Le Ru, D. Conlong, D. Cugala, B. Defabachew, T. Matama-Kauma, B. Pallangyo, J. Van Den Berg

All Peer-Reviewed Publications

Currently, the systematics of the African noctuid stem borers of the subtribe Sesamiina, which include major pests of cereals, is confused. In addition, their ecology is poorly known, as are the factors influencing their evolution. In this paper, we address these shortcomings for two genera of the Sesamiina, Sciomesa Tams & Bowden and Carelis Bowden. Mixed Bayesian phylogenetic analysis, which included their host plants and two mitochondrial genes, showed the genus Sciomesa to be polyphyletic. Two new genera were created, Pirateolea and Feraxinia. The genus Carelis proved to be paraphyletic and was subdivided into two sub-genera. The genera Sciomesa, Carelis …

Approaches To Identify Surface Proteins Of Anaplasma Phagocytophilum Dense-Cored Organisms As Adhesins To Human P-Selectin Glycoprotein Ligand-1, Matthew Troese

Theses and Dissertations

Anaplasma phagocytophilum is an obligatory intracellular bacterium that infects neutrophils to cause human granulocytic anaplasmosis. Sialyl Lewis x (sLex)-modified P-selectin glycoprotein ligand-1 (PSGL-1) is the confirmed receptor utilized by A. phagocytophilum to bind and invade human neutrophils and myeloid cell lines. As an obligate intracellular pathogen, the binding of A. phagocytophilum to a host cell receptor is a prerequisite step for entry and replication, and thus its survival. However, the bacterial adhesins mediating this process have yet to be identified. In this study, we sought to identify surface proteins of A. phagocytophilum as putative adhesins. A. phagocytophilum undergoes a biphasic …

Characterization Of Anti-Proteolytic And Anti-Proliferative Activities Of Pentagalloylglucose; Its Potential Application As A Therapeutic Agent In Vascular Diseases, Chaitra Cheluvaraju

All Dissertations

Cardiovascular diseases are the leading causes of mortality in the United States and will cost around $500 billion this year alone. Elevated proteolytic activity, increased proliferation and migration of vascular smooth muscle cells are hallmarks of atherosclerosis, stenosis and aortic aneurysms. These diseases often manifest the transdifferentiation of vascular smooth muscle cells into osteoblast-like cells followed by deposition of hydroxyapatite–like mineral in the arterial walls.
Currently, there are no standard treatments available for vascular calcification or aneurysms. Atherosclerosis treatment options are limited to statins while balloon angioplasty and stenting – surgical procedures for stenosis, often end in restenosis. Therefore, we …

A Reasoning Framework For Dependability In Software Architectures, Tacksoo Im

All Dissertations

The degree to which a software system possesses specified levels of software quality attributes, such as performance and modifiability, often have more influence on the success and failure of those systems than the functional requirements. One method of improving the level of a software quality that a product possesses is to reason about the structure of the software architecture in terms of how well the structure supports the quality. This is accomplished by reasoning through software quality attribute scenarios while designing the software architecture of the system.
As society relies more heavily on software systems, the dependability of those systems …

Understanding Gafp, A Plant Lectin With Broad Spectrum Inhibitory Activity, Alexis Nagel

All Dissertations

South Carolina and Georgia are the largest peach producing regions in the Southeastern United States, generating about $60 million worth (~90,000 tons) of fruit per year on average. Peaches and other stone-fruits (Prunus sp.) can be afflicted by a variety of root-associated diseases which negatively impact annual yield and long-term tree mortality. An engineered Prunus rootstock with enhanced resistance to soil-borne pathogens would therefore be of great benefit to the Southeastern peach industry. The Gastrodia anti-fungal protein (GAFP) is a monocot mannose-binding lectin which is able to inhibit the growth of multiple species of plant pathogenic fungi. Previous findings from …

The purpose of this study is to compare and investigate conceptual frameworks that represent the relationship between golfers' perceived …

Predictors And Outcomes Of Occupational Commitment Profiles Among Nurses, Lindsay Sears

All Dissertations

Occupational turnover is a costly problem afflicting much of the nursing industry, and occupational commitment is a strong predictor of withdrawal from one's profession. Traditional organizational research examines most commitment-behavior relationships from a variable-centered perspective, focusing on the relationships between constructs. The present study adopts a configural, or person-centered approach aimed at identifying and describing clusters of individuals who share a similar set of occupational commitment mindsets. The present study extends current literature by a) investigating the existence of several occupational commitment profiles and describing their characteristics; b) examining situational and demographic predictors of profile membership; and c) testing differences …

Preparation And Studies Of Fluorescent Carbon Nanomaterials, Xin Wang

All Dissertations

There have been rapid advances in the development and applications of semiconductor quantum dots (QDs) represented by CdSe/ZnS. However, a serious limitation of these QDs is the necessary use of toxic heavy metals. Fluorescent 'carbon dots' (surface passivated carbon nanoparticles) are developed as alternative to classical semiconductor QDs.
The carbon dots could be made to be highly fluorescence, with emission quantum yields close to 60%. Their optical properties resemble bandgap transitions found in nanoscale semiconductors, suggesting that carbon particles at the nanoscale acquire essentially semiconductor-like characteristics.
The fluorescence in carbon dots could be quenched efficiently by electron acceptor or donor …

The Effect Of Omega-3 Polyunsaturated Fatty Acids Derived From Various Sources On Bone Metabolism In Growing Female Rats, Robin E. Lukas

Graduate Theses, Dissertations, and Problem Reports (ETD)

Bone loss may be lessened if bone mass and strength are increased by optimizing nutrition intervention. Omega-3 polyunsaturated fatty acids (o-3 PUFAs) have been suggested to improve bone mineralization and microarchitecture by affecting mineral balance and lipid peroxidation. However, the sources of the o-3 PUFA differ in the types of o-3 PUFA, ratios, and structural form. Therefore, the study objective was to determine the effect of o-3 PUFAs from different sources on bone mineral and microarchitecture and explore potential associations. Growing (28 day) female Sprague-Dawley rats were randomly assigned (n=10/group) to a high fat 12% (weight) diet consisting of either …
