Synthesis And Antimicrobial Activities Of S,S'-Heterosubstituted Disulfides, Praveen Ramaraju

USF Tampa Graduate Theses and Dissertations

Antibiotic resistance is a particularly critical health concern and has increased dramatically over the past two decades. For over a decade the Turos laboratory has been designing small molecules to target pathogenic microbes such as Staphylococcus aureus and the resistant variants like methicillin-resistant Staphylococcus aureus (MRSA). Previously, N-thiolated Β-lactams, N-thiolated 2-oxazolidinones and aromatic disulfides that were synthesized in Dr. Turos' lab have shown strong activity against these bacteria. The present work describes the synthesis and antimicrobial activities of a related structural class called S,S'-heterosubstituted disulfides. For ages, sulfur (elemental) has been used as an antibacterial for controlling infestation and bacterial …

Apparent Total Evaporative Resistance For Clothing Ensembles At High Heat Stress Levels, Patrick Rodriguez

USF Tampa Graduate Theses and Dissertations

Donning protective clothing for mitigation of hazard from chemical agents poses a problem in the form of heat stress. When choosing protective clothing, many factors must be taken into account including insulative properties and evaporative resistance. This study calculated and compared R_e,T,a for three clothing ensembles at levels of heat stress past the level of compensation for heat gain to determine if R_e,T,a values varied or remained the same with changes in heat stress level. A three-way mixed model analysis of variance demonstrated significant differences for estimated R_e,T,a values among ensembles, heat stress levels and interactions among …

Egyptian Body Size: A Regional And Worldwide Comparison, Michelle H. Raxter

USF Tampa Graduate Theses and Dissertations

Human body size and limb proportions can provide important information about adaptation, population movements, and health disparities. This study investigated changes in body size and limb proportions of adult Egyptians temporally and geographically in relation to climatological, sociopolitical and economic developments. It was predicted that Egyptian groups that experienced more environmental stress would be shorter and exhibit less sexual dimorphism. It was also predicted that Egyptians would be intermediate between higher and lower latitude populations in body form and limb length ratios. The main skeletal sample consisted of 492 males and 528 females, all adults from the Predynastic and Dynastic …

Characterization Of Aminopeptidase Pepz In Staphylococcus Aureus Virulence, Tiffany Marie Robison

USF Tampa Graduate Theses and Dissertations

Staphylococcus aureus is a remarkably successful pathogen, accounting for an estimated 95,000 invasive infections annually in the U.S. alone. The burden of MRSA infections on public healthcare continues to rise, particularly with the continued spread of antibiotic resistant strains and the hyper-virulent CA-MRSA strains. The pathogenic nature of S. aureus can be attributed to the cache of virulence factors encoded within the genome of this organism. Typically, these are secreted toxins which directly interact with the host during infection, and facilitate pathogenesis. A previous screen in our laboratory investigating proteases in S. aureus identified a mutant in aminopeptidase Z as …

The Culture Of Mean: Gender, Race, And Class In Mediated Images Of Girls' Bullying, Emily Davis Ryalls

USF Tampa Graduate Theses and Dissertations

This dissertation examines narratives about female bullying and aggression through mediated images of "mean girls." Through textual analysis of popular media featuring mean girls (television shows such as Gossip Girl and films like Mean Girls), as well as national news coverage of the case of Phoebe Prince, who reportedly committed suicide after being bullied by girls from her school, this feminist examination questions how the image of the mean girl is raced and classed. This dissertation values an interdisciplinary approach to research that works to make sense of the forces that produce bodies as gendered, raced, and classed.

Secreted Factors From Human Umbilical Cord Blood Cells Protect Oligodendrocytes From Ischemic Insult, Derrick Rowe

USF Tampa Graduate Theses and Dissertations

Oligodendrocytes (OL)s are the dominant cell type in the white matter and are integral for synaptic transmission essential for proper neuronal communication between brain areas. Previous studies have shown that intravenous administration of the mononuclear fraction of human umbilical cord blood (HUCB) cells in rat models of stroke reduced white matter injury, gray matter injury and behavioral deficits. Yet the mechanisms used by HUCB cells remain unknown in ischemic injury. These studies will investigate both in vitro and in vivo approaches to elucidate this mechanism in OLs. When mature primary OLs were coincubated with HUCB cells, HUCB cells secreted soluble …

Visual Search For Smoking Stimuli: Detection And Distraction, Jason A. Oliver

USF Tampa Graduate Theses and Dissertations

Extensive research has shown that the attentional systems of addicted individuals are biased towards drug-related stimuli, but despite several decades of effort these results have frequently been inconsistent. Though commonly believed to result from addiction and dependence, cognitive research would suggest that frequent exposure to drug-related stimuli could affect the attentional processing of drug-related cues even if no actual drug use occurs. The present investigation examined attentional bias for smoking cues using a novel visual search paradigm amongst smokers currently in nicotine withdrawal and fully satiated smokers, as well as a non-smoker control group. Variables related to smoking behavior, as …

The Threat To Democracy In Brazil's Public Sphere, Daniel Nettuno

USF Tampa Graduate Theses and Dissertations

This thesis looks at the nature of violence with its endemic, and increasingly epidemic presence in Brazil. I analyze the structure of the justice system, police force, and the many governmental security programs in order to better explain why Brazil is so violent and its government has been unable to control this violence. Living under violent conditions, Brazil has become a society where the efficient functioning of the public sphere has been undermined. This public space, shared by citizens, is what many academics believe to be a critical component of a robust and functioning democracy. In Brazil, it is shown, …

Tracking The Use Of Leed® In Facilities For Higher Education, Shannon Chance

Articles

America’s 4391 institutions of higher learning own roughly 240,000 buildings according to The Carnegie Foundation for the Advancement of Teaching (2009) and the United States Green Building Council [USGBC] (n.d.). Most of these buildings’ designs reflect a time when energy was cheap and material abundant. Throughout the past century, building designs frequently ignored their surroundings, usurped energy at appalling rates, and did little to teach inhabitants respect for the environment

Rast Model: Simulation Of Tensiotraces To Facilitate Drophad Engineering, Philippe Pringuet, Norman Mcmillan, G. Doyle, Stephen Smith, M. O'Neill, Sebastian Riedel

Articles

Tensiography is a technique that determines the physical and chemical properties of a liquid by illuminating a growing pendant drop from within using a source fibre. Light reflected internally at the surface of the drop is recieved by a collector fibre and is converted into an electric signal called a tensiotrace, which is a graph of reflected light as a function of drop volume. The instrument obtaining this signal is called multianalyser. A numerical model that simulates tensiotraces through a raytracing analysis (RAST - Raytracing Analysis for the Simulation of Tensiotraces) of the multianalyser as been developed to define theoretically …

Local authorities in the Republic of Ireland are being required to upgrade their housing stocks. Due to the current economic recession local authorities, while receiving grants from central government, are struggling financially to upgrade their housing stocks. More cost efficiency is required when undertaking works. The research examines how the cost of upgrading Dublin City’s local authority housing built prior to the introduction of the 1991 building regulations can be reduced through applying lean thinking. This paper proposes a lean model for the upgrading of local authority housing in Dublin City. The paper concludes with an outline of where monies …

Racial Redistricting In A Post-Racial World, Gilda R. Daniels

Cardozo Law Review

The 2011 redistricting will provide some interesting challenges for minority voting rights. How can we preserve minority electoral opportunities and gains in the wake of Bartlett v. Strickland and Georgia v. Ashcroft? What is the impact on future voting rights litigation and are coalition district claims viable as an opportunity to continue the electoral gains made since the passage of the Voting Rights Act? Are majority-minority districts safe from legislative backsliding? The Supreme Court's construed admonitions against race-conscious redistricting in recent cases may become cautionary tales. This Article discusses the central role the Voting Rights Act should play in …

Four inter-professional student teams, rotated through the four stations and discussed questions about professional …

A Taxonomy Of Virtual Work, Miriam A. Cherry

Georgia Law Review

Millions of people worldwide entertain themselves or
supplement their incomes-or both-by meeting with
fellow employees as avatars in virtual worlds such as
Second Life, solving complicated problems on websites like
Innocentive, or casually "clicking" to make money for
simple tasks on Amazon.com's Mechanical Turk. Virtual
work has great promise- increasing efficiency by reducing
the time and expense involved in gathering workers who
live great distances apart,and allowing for efficient use of
skills so that the whole is truly greater than the sum of its
parts. At the same time, virtual work presents its own
unique series of challenges, and regulation …

Too Close To Home: Limiting The Organizations Subsidized By The Charitable Deduction To Those In Economic Need, Shannon Weeks Mccormack

Articles

The charitable deduction allows taxpayers to deduct amounts donated to organizations pursuing statutorily designated purposes from their otherwise taxable income. By lowering the after-tax cost of giving and encouraging taxpayers to donate more than they otherwise would, the charitable deduction subsidizes a broad variety of organizations. Some of these organizations provide widespread societal benefits, while others provide narrower benefits that remain closer to the taxpayer-donor’s home. To evaluate these current laws, this Article focuses on efficiency criteria, which limit subsidized organizations to those with donor support that does not cover the costs needed to optimally provide goods and services. Existing …

Labor Pains In The Academy, Lisa M. Tillmann Ph.D.

Faculty Publications

This piece offers autoethnographic reflections on crossroads to which many academics come: whether to seek (or postpone or avoid) parenthood and when. The author deeply explores the personal (her own trajectories from daughter and sister to potential mother and from graduate student to full professor) in order to reflect on structural constraints associated with graduate education, the academic job market, and institutional policies and politics.

The Beauty And The Beast: Civil Society And Nationalisms In Bosnia And Herzegovina, Joan Davison

Faculty Publications

Both ethnic nationalism and liberal civic nationalism exist with historical precedents in Bosnia-Herzegovina. Many elected elites privilege extremist ethnic nationalism. The power-sharing structure of the Dayton Peace Accords institutionalizes their influence and permits the current political stalemate. Further, a legacy of authoritarianism vitiates a political culture supportive of elite accountability and mass responsibility. Yet a nascent civil society witnesses to the past and potential future of liberal cosmopolitanism. This research includes interviews with leaders and members of civil society organizations to assess the impediments to and strength of civil society as a vehicle to promote civic nationalism. While interviewees acknowledge …

Environmental Migrants And The Future Of The Willamette Valley: A Preliminary Exploration, Alison Wicks

Institute of Metropolitan Studies Publications

This report reviews existing data and research on predicted impacts of climate change in the Northwestern United States, and specifically focuses on the level of preparedness to accommodate new population growth due to climate migration in Oregon’s Willamette Valley. Climate change impacts in Oregon are predicted to be less severe than in other areas of the country. Generally, models project warmer, wetter winters and hotter, drier summers in the Willamette Valley and other areas west of the Cascade Range. This will likely make the Willamette Valley a more desirable place for environmentally displaced people to locate. This report considers how …
