Hiv-Related Stigmatization In Treatment Settings: Effects On Patient Comfort, Risk Disclosure, And Treatment Decisions, Jessica Deanne Naughton

Psychology - Dissertations

The major focus for the present study was to examine the effects of provider stigmatization on the medical care of HIV+ patients, by using an experimental paradigm and examining a conceptual framework to clarify the relationship between provider stigmatization and negative treatment outcomes. Initial qualitative findings from focus groups (n = 18) indicated that several key elements of stigmatizing treatment experiences included judgmental and condescending language, patient avoidance, increased physical distance between patient and provider during conversations and procedures, and use of extra, unnecessary precautions (e.g. use of extra gloves, masks). These provider behaviors were experimentally manipulated and incorporated into …

Linear Sigma Models In Qcd And S3 Symmetry For Neutrinos, Muhammad Naeem Shahid

Physics - Dissertations

This thesis has two parts with different topics in particle physics. In part I, we consider various linear sigma models and their applications to scalar mesons. It is shown that the tree amplitude for ππ scattering in the minimal linear sigma model has an exact expression which induces an infinite geometric series in which the pattern for both the I = 0 and I = 2 s-wave scattering lengths to orders $p^2$, $p^4$ and $p^6$ seems to agree with chiral perturbation theory predictions. The model is then gauged to study the mass differences between the vector meson and the axial …

Microstrip Superconducting Quantum Interference Devices For Quantum Information Science, Michael Paul Defeo

Physics - Dissertations

Quantum-limited amplification in the microwave frequency range is of both practical and fundamental importance. The weak signals corresponding to single microwave photons require substantial amplification to resolve. When probing quantum excitations of the electromagnetic field, the substantial noise produced by standard amplifiers dominates the signal, therefore, several averages must be accumulated to achieve even a modest signal-to-noise ratio. Even worse, the back-action on the system due to amplifier noise can hasten the decay of the quantum state. In recent years, low-noise microwave-frequency amplification has been advancing rapidly and one field that would benefit greatly from this is circuit quantum electrodynamics …

How Much Does This Tick You Off? Online Rejection And Criticism Lead To Negative Affect And Retaliatory Aggression, Gina Masullo Chen

Mass Communications - Dissertations

A three-condition (rejection, criticism, control) single-factor experiment (N = 77) on a mock social-networking site similar to Facebook reveals that even a slight rejection - not being allowed to join groups on the site - lead to increases in self-reported negative affect and retaliation against the site and the rejecting groups compared to a control. Subjects who were accepted into the groups but then criticized experienced the same increases in negative affect and retaliatory aggression, as those who were not allowed to join. In addition, men showed heightened retaliatory aggression compared to women and responded differently to criticism than women. …

Nitric Oxide Releasing Polymers For Vascular Graft Applications, Ifeanyi U. Onyejekwe

Biomedical and Chemical Engineering - Dissertations

Nitric oxide [NO] is an endogenous gas involved in a multitude of physiological functions, ranging from vasodilatation, inflammatory response to inhibition of platelet aggregation. Significant interest exists for therapeutic application of exogenous NO, particularly for the improvement of foreign-body responses of biomaterials. One challenge amongst several others that must be taken into consideration is NO's short half-life, ranging from 2-3 s, in physiological systems. Researchers have worked on synthesizing materials, formally referred to as NO donors/NONOates capable of preserving NO and spontaneous gas release upon contact with blood under physiological conditions. Two groups of these commercially available NO donors known …

Molecular Mechanisms Of Aging And Immune System Regulation In Drosophila., Ioannis Eleftherianos, Julio C. Castillo

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Aging is a complex process that involves the accumulation of deleterious changes resulting in overall decline in several vital functions, leading to the progressive deterioration in physiological condition of the organism and eventually causing disease and death. The immune system is the most important host-defense mechanism in humans and is also highly conserved in insects. Extensive research in vertebrates has concluded that aging of the immune function results in increased susceptibility to infectious disease and chronic inflammation. Over the years, interest has grown in studying the molecular interaction between aging and the immune response to pathogenic infections. The fruit fly …

Pediatrics Faculty Publications

Background: In this single-site study, we evaluated the feasibility of a parent-clinician communication intervention designed to: identify parents' rationale for the phase I, do-not-resuscitate (DNR), or terminal care decision made on behalf of their child with incurable cancer; identify their definition of being a good parent to their ill child; and provide this information to the child's clinicians in time to be of use in the family's care.

Methods: Sixty-two parents of 58 children and 126 clinicians participated. Within 72 hours after the treatment decision, parents responded to 6 open-ended interview questions and completed a 10-item questionnaire about the end-of-life …

Evaluation Of The Press Calibration Methods By Simulation, Yi Wang

Theses

Press calibration is an approach to adjust the behavior of ink, paper, and press with the use of a CTP platemaking system to achieve a specified reference printing condition. Reference printing condition defines a common color space for color image data exchange between various output devices. The advantage of a reference printing condition is to improve color image quality and reduce cost and time. Corner points of the color gamut, TVI curves, and grey reproduction are the three significant elements in a reference printing condition, which make them essential in press calibration. There are usually two press runs in press …

Aggregation Behavior Of The Southern Chinch Bug (Hemiptera: Blissidae), Karla M. Addesso, Heather J. Mcauslane, Ron Cherry

Agricultural and Environmental Sciences Faculty Research

The southern chinch bug, Blissus insularis Barber, forms dense, multigenerational aggregations in St. Augustinegrass lawns leading to grass death from sap feeding. We conducted laboratory bioassays to better understand the signals responsible for the formation and maintenance of southern chinch bug aggregations. In small arena assays, chinch bugs demonstrated a stronger aggregation response over time and aggregated more often on or beneath St. Augustinegrass leaf blades than on or under artificial leaf-like shelters constructed from white or green paper. In Y-tube olfactometer assays, bugs of different age and sex were attracted to volatiles from mixed-sex chinch bug aggregations and showed …

Un Modo Più Chiaro: Francesco Scannelli, Guercino And The Physiology Of Style, James Hutson

Faculty Scholarship

The mid-seicento in Italy witnessed a sustained proliferation of writers on art scattered throughout more regions than had been common in the previous century, leading to an era defined by arguments over the qualities and values of style.1 In the Preface for his Vite de 'pittori, scultori ed architetti of ca.1673-79, Giovanni Battista Passeri lamented the fact that: «Today it is fashionable for painters to do nothing but squabble among themselves about manner, taste, and style, and this arose because the reasoning is not established according to solid principles ».2 The querulous nature of the age has made it difficult …

Synthesis And Characterization Of Graphene Oxide, Jeremy A. Waddell, Arthur Cheng, Bin Chen

STAR Program Research Presentations

Graphene, a single atomic layer of sp² carbon atoms, has gotten a lot of attention from the scientific community because of its excellent mechanical and electronic properties. The mechanical exfoliation methods used to obtain graphene nanosheets are not effective for large scale manufacturing, so scalable synthesis approaches from structurally similar compounds are of great scientific interest. Graphene oxide is one such compound which is synthesized through the oxidation of graphite powder. The oxidation was performed using a modification of the previous experimental procedure. After synthesis, the powder was fabricated into graphene oxide films through vacuum filtration and transfer to …

Developing Software For The Beam Line Control Systems, Jennifer A. Beltran, Stefan Mannsfeld

STAR Program Research Presentations

Scientists from all around the world come to National Laboratories to perform X-ray absorption spectroscopy (XAS) experiments. XAS experiments are used to determine the chemistry component of an object or material of interest. In a typical XAS experiment, the incident X-ray beam energy is varied in a region close to a fundamental electronic transition of the atom(s) of interest. The data has to be collected most densely in the immediate vicinity of the transition (also called edge). XAS scans are therefore often comprised of differently dense regions. The user can define how the data will be collected in each region …

Classification Of Multi-Domain Glycoside Hydrolases To Aid In The Enzymatic Production Of Biofuels From Biomass, Emi Leonard, Gregg Beckham, Deanne Sammond, Michael Crowley

STAR Program Research Presentations

Biomass conversion to renewable biofuels provides an alternative to conventional fossil-fuel based transportation fuels and a means to reduce dependence on foreign oil. However, plant cell walls have evolved to be quite resistant to enzymatic deconstruction, a phenomenon generally termed biomass recalcitrance. As enzymes represent a substantial cost in biofuels production, there is significant impetus to understand and improve their efficiency in converting cell wall carbohydrates to fermentable sugars. Much research has been conducted on single "free" enzymes with one catalytic unit per protein and on the much larger, complexed "cellulosomes" with many tens of catalytic units per protein, but …
