Determinants Of College Students' Opinions Towards Felon Voting Rights: An Exploratory Study, Edwards Brenda Cherie Dawson Jan 2007

Determinants Of College Students' Opinions Towards Felon Voting Rights: An Exploratory Study, Edwards Brenda Cherie Dawson

Theses and Dissertations

The disenfranchisement of felons follows a long American tradition of selectively granting the most coveted democratic tradition - voting. As a collateral "civil" consequence to criminal conviction that is legally deemed as non-penal, felon voting prohibitions have been used as an exclusionary tool for certain otherwise eligible voting populations. Current research finds that African-Americans individually and collectively may experience diminished voting power due to felon voting laws (Uggen & Manza, 2002; Manza & Uggen, 2004; King & Mauer, 2004). The purpose of this research is to examine opinions toward felon voting prohibitions in a state that has one of the …

The Influence Of Adenoviral Infection And The Group Via Calcium-Independent Phospholipase A2 On Hepatic Lipid Metabolism, William Palmer Wilkins Iii Jan 2007

The Influence Of Adenoviral Infection And The Group Via Calcium-Independent Phospholipase A2 On Hepatic Lipid Metabolism, William Palmer Wilkins Iii

Theses and Dissertations

Sterol regulatory element-binding proteins (SREBP) are transcription factors that regulate genes involved in lipid metabolism especially in the liver. Therefore, hepatic SREBP is significant regulator of systemic lipid metabolism. Evidence demonstrates that insulin and dietary unsaturated fatty acid (UFA) regulate SREBP1 expression and subsequent SREBP1-mediated gene transcription, events that in many instances result in modulation of systemic fatty acid and triglyceride (TG) homeostasis. A series of investigations was designed to uncover novel regulators of SREBP1. Dietary and exogenous addition of UFA has been shown to regulate SREBP function yet, an endogenous source of UFA capable of modulating SREBP remains elusive. …

Cognitive Mechanisms Of Memory Impairment Following Traumatic Brain Injury, Mark D. Whiting Jan 2007

Cognitive Mechanisms Of Memory Impairment Following Traumatic Brain Injury, Mark D. Whiting

Theses and Dissertations

Memory impairment is common following traumatic brain injury (TBI). In recent years, researchers have demonstrated that the processes underlying memory formation (working memory, encoding, consolidation, and retrieval) are interrelated but dissociable events.The following study was designed to determine how these processes contribute to memory impairment following experimental TBI in the rat. Experiment 1 indicated thatTBI induces severe working memory deficits in a delayed non-matching-to-place task.Although all animals displayed intact acquisition, only injured animals displayed poor performance as the delay between the sample and choice phases was increased.Experiment 2 was designed to determine if TBI produces a transient period of posttraumatic …

Invisible Green, Amanda Sauer

Theses and Dissertations

How is nature conceived today, a generation into the environmental movement? Many contemporary artists grapple with how to reconcile our inheritance of both a precarious natural world and the culture that created it. My work investigates the subtle intricacies of our relationship with nature. I use photography to develop a way of seeing that points to the often-unnoticed nature in front of us. In particular, my work recognizes and re-imagines nature's deep connections in the context of our ecologically changed world.

Beyond The Threshold: Allusions To The ÒrìsÀ In Ana Mendieta's Silueta Series, Latricia M. January Jan 2007

Beyond The Threshold: Allusions To The ÒrìsÀ In Ana Mendieta's Silueta Series, Latricia M. January

Theses and Dissertations

The Cuban-born artist Ana Mendieta (1948-1985) created the Silueta Series during the 1970s and ‘80s. It consists of earth-body works in situ featuring the silhouette of the artist's body fashioned from mud, plants, rocks, gunpowder and other materials. Underlying the creation of the Silueta Series is Mendieta's belief that the elements are sentient and powerful beings. This perception is particularly strong in the Afro-Cuban religion Santeria, a creolized form of the Òrìsà tradition of the Yoruba of West Africa introduced to the Americas during the trans-Atlantic slave trade. While scholars have noted Mendieta's incorporation of Santeria in her art, a …

Disparities In The Use Of Emergency Contraceptives, Rebecca Dallman Jan 2007

Disparities In The Use Of Emergency Contraceptives, Rebecca Dallman

Theses and Dissertations

Purpose: Unintended pregnancies are often a burden to pregnant women and to the health care system. The rates of unintended pregnancies have decreased since the wide use of contraceptives has increased; however, young women, women with low income, and racial/ethnic minorities are more likely to use contraceptives inconsistently, which increases the risk of an unintended pregnancy. This risk could be reduced with the proper use of emergency contraceptives (ECs).Methods and Analysis: A cross-sectional study was conducted using the data from the female respondents of the 2002 Cycle 6 NSFG. Logistic regression was used to determine rates of use of ECs …

An Empirical Study Of Executive Management Team Compensation And Company Performance, Gregory A. Jonas Jan 2007

An Empirical Study Of Executive Management Team Compensation And Company Performance, Gregory A. Jonas

Theses and Dissertations

Increasing compensation disclosures mandated by the Securities Exchange Commission provide transparency that allows more shareholders to question the results produced by highly compensated executives. The popular business press often decries the apparent imbalance between executive pay and firm performance. Published academic research has responded with hundreds of studies attempting to explain executive pay in terms of firm performance. The preponderance of these studies focus on Chief Executive Officers. This study empirically examines executive compensation for team effects on future firm performance.Applying a firm specific fixed-effects model to a sample of 13,021 firm-year observations from ExecuComp, the current study regresses top …

Achieving High Performance In Local Government: Linking Government Outcomes With Human Resource Management Practices, Richard F. Huff Jan 2007

Achieving High Performance In Local Government: Linking Government Outcomes With Human Resource Management Practices, Richard F. Huff

Theses and Dissertations

Historically public sector personnel policies and practices have been targets of reform. These reforms consisted of transferring private sector techniques to a public sector perceived to be more bureaucratic and less efficient. Private sector research is replete with evidence of a connection between "superior" human resource management (HRM) practices and the performance outcome of profitability. Public sector outcomes are more difficult to connect directly to management practices. As a result, the focus of public sector reform has become one of improving the processes of management rather than improving the outcomes of government. The linkage between reform and outcome is assumed.This …

Visual Contributions To The Vestibulo-Ocular Reflex During Balance Recovery Tasks, Mark D. Diehl Jan 2007

Visual Contributions To The Vestibulo-Ocular Reflex During Balance Recovery Tasks, Mark D. Diehl

Theses and Dissertations

Introduction: The Vestibulo-ocular reflex (VOR) is quantified by computing the ratio of head angular velocity and eye angular velocity (VOR Gain). This measure only includes head angular movements; linear translations are not accounted for. These investigations postulate an alternative method of VOR quantification, one that assesses retinal image stability during head angular and linear movements (Foveal fixation (FF)). This method was used to assess the role of vision in balance reactions. Methods: Experiment 1 : Ten Young subjects were fitted with an eye tracker linked to an EM kinematic recording system. This allowed for the recording of head, trunk and …

Development And Validation Of A Computational Musculoskeletal Model Of The Elbow Joint, Justin Paul Fisk Jan 2007

Development And Validation Of A Computational Musculoskeletal Model Of The Elbow Joint, Justin Paul Fisk

Theses and Dissertations

Musculoskeletal computational modeling is a versatile and effective tool which may be used to study joint mechanics, examine muscle and ligament function, and simulate surgical reconstructive procedures. While injury to the elbow joint can be significantly debilitating, questions still remain regarding its normal, pathologic, and repaired behavior. Biomechanical models of the elbow have been developed, but all have assumed fixed joint axes of rotation and ignored the effects of ligaments. Therefore, the objective of this thesis was to develop and validate a computational model of the elbow joint whereby joint kinematics are dictated by three-dimensional bony geometry contact, ligamentous constraints, …

Lucidity, Sarah Rebekah Byrd Mizer Jan 2007

Lucidity, Sarah Rebekah Byrd Mizer

Theses and Dissertations

This thesis focuses on space, the in-between-ness that exists amidst mental and physical experience. Pith explains personal attachments and rooting systems. The thesis continues with Blessing, narrating love then loss, and finishes with a recipe for making a tomato sandwich. Blessing is followed by Materialize, a collective view of cyclical learning and meandering paths. Finally, the paper concludes with a quirky Women and Swarovski encrusted skulls, which matter-of-factly lists artists (all of whom happen to be women) whose works I find particularly compelling; and also notes on general trends in art I find interesting in a much less obvious manner. …

Cd23'S Role As A Negative Regulator Of Allergic Disease: In Vivo Effects Of Murine Cd23 Destabilization And Allelic Mutations, Jill Wallace Ford Jan 2007

Cd23'S Role As A Negative Regulator Of Allergic Disease: In Vivo Effects Of Murine Cd23 Destabilization And Allelic Mutations, Jill Wallace Ford

Theses and Dissertations

Through underexpression and overexpression studies, CD23 has been shown to negatively regulate IgE production. To investigate CD23 destabilization and its effects on CD23 shedding and IgE synthesis in vivo, we utilized an anti-CD23 stalk monoclonal (19G5) which has previously been shown to enhance proteolysis of CD23 in vitro. Compared to isotype control-treated mice, mice injected with 19G5 displayed enhanced serum soluble CD23 and IgE. Because 19G5 injection substantially enhanced CD23 shedding, it was useful in investigating the identity of the CD23 sheddase. 19G5 enhanced CD23 shedding in ADAM8-/-, ADAM9-/-ADAM15-/-, and ADAM9-/-ADAM12-/-ADAM15-/- mice, ruling out these ADAMs as candidate CD23 sheddases. …

Investigation Of Age Related Differences In The Rewiring Of P2-Olfactory Receptor Neurons, Daniel Joseph Galante Jan 2007

Investigation Of Age Related Differences In The Rewiring Of P2-Olfactory Receptor Neurons, Daniel Joseph Galante

Theses and Dissertations

Olfactory receptor neurons (ORNs) maintain the ability to regenerate. These neurons reside in the olfactory epithelium and project axons that connect to the olfactory bulbs. Despite the diffuse distribution of ORNs in the olfactory epithelium, they converge at discrete glomeruli in the olfactory bulb. In the P2 IRES tau-lacZ mouse, the P2 ORN subtype has been previously mapped to two glomeruli, using X-gal staining. To determine if age affects ORN regeneration, left olfactory nerve transections were performed on P2 mice from immature (five-weeks old) and mature (1 6-weeks old) groups. Following recovery, the olfactory bulbs were processed to observe ORN …

Concurrent Whitening And Orthodontic Treatment, Jason Thomas Gladwell Jan 2007

Concurrent Whitening And Orthodontic Treatment, Jason Thomas Gladwell

Theses and Dissertations

The aim was to evaluate whether a whitening system, when used during the final stages of orthodontics, would yield results comparable to whitening alone. Patients were assigned to either the control (n=20) or experimental (n=26) groups. At T1, patients were given a ten day supply of Trèswhite™ by Opalescence®, instructions on use, and initial shade determination was made and photographs were taken. At T2 and T3, shade determination was accomplished and updated photographs were taken. Whitening of the teeth occurred in both groups on average, but significantly more whitening was experienced in the experimental group (p < 0.004). An average of 87% of teeth whitened during orthodontic treatment compared to 97% of control teeth (p < 0.01) were judged to be uniform in appearance. In conclusion, the data do not contraindicate the concurrent accomplishment of teeth whitening during orthodontic treatment.

Biologically-Inspired Translation, Scale, And Rotation Invariant Object Recognition Models, Myung Woo

Theses

The ventral stream of the human visual system is credited for processing object recognition tasks. There have been a plethora of models that are capable of doing some form of object recognition tasks. However, none are perfect. The complexity of our visual system is so great that models currently available are only able to recognize a small set of objects. This thesis revolves analyzing models that are inspired by biological processing. The biologically inspired models are usually hierarchical, formed after the division of the human visual system. In such a model, each level in the hierarchy performs certain tasks related …

An Analysis Of Connectivity, Tayeb Al Karim Jan 2007

An Analysis Of Connectivity, Tayeb Al Karim

Theses

Recent evidence in biology indicates crossmodal, which is to say information sharing between the different senses, influences in the brain. This helps to explain such phenomenon as the McGurk effect, where even though a person knows that he is seeing the lip movement “GA” and is hearing the sound “BA”, the person usually can’t help but think that they are hearing the sound “DA”. The McGurk effect is an example of where the visual sense influences the perception of the audio sense. These discoveries transition old feedforward models of the brain to ones that rely on feedback connections and, more …
