Crystal Engineering Of Multi-Component Crystal Forms: The Opportunities And Challenges In Design, Heather Dawn Marie Clarke

USF Tampa Graduate Theses and Dissertations

There is heightened interest to diversify the range of crystal forms exhibited by active pharmaceutical ingredients (APIs) in the pharmaceutical industry. The crystal form can be regarded as the Achilles' heel in the development of an API as it directly impacts the physicochemical properties, performance and safety of the API. This is of critical importance since the crystal form is the preferred method of oral drug delivery by industry and regulatory bodies. The ability to rationally design materials is a lucrative avenue towards the synthesis of functional molecular solids with customized physicochemical properties such as solubility, bioavailability and stability. Pharmaceutical …

The surface chemistry of the magnetic nanoparticle proves critical to obtaining a homogenous and well separated high density dispersion in PMMA. Theoretical studies found in the literature have indicated that surface interface energy …

Regulation Of Natural Killer Cells: Ship-1, 2b4, And Immunomodulation By Lenalidomide, Nicole Renee Fortenbery

USF Tampa Graduate Theses and Dissertations

Natural Killer cells (NK) are critical components of the innate immune system. Often referred to by their morphology, these large granular lymphocytes (LGLs) are bone marrow-derived lymphocytes and can be found throughout the body. NK cells reside in the liver, lymph nodes, spleen, thymus, and mucosal-associated lymphoid tissues (MALT). Importantly, NK cells also circulate throughout the blood where they function as surveyors of the body and are armed to eliminate malignant, infected, damaged, or foreign cells.

NK cells function by a dual receptor system. That is, NK receptors are broadly categorized as inhibitory or activating. It is a fine balance, …

1-Deoxy-D-Xylulose-5-Phosphate Synthase (Dxs) Mechanistic Study And Its Implication In The Development Of Novel Antibiotics And Antimalarials, Sumit Handa

USF Tampa Graduate Theses and Dissertations

Isoprenoids are the largest family of biologically active compounds, synthesized by five carbon subunits namely isopentenyl pyrophosphate (IPP) and dimethylallyl pyrophosphate (DMAPP). For long time the mevalonate-dependent (MVA) pathway has been considered as the sole source of IPP and DMAPP, until recently a new non-mevalonte dependent (NMVA) pathway was discovered. This new pathway utilizes entirely different set of enzymes for isoprenoids synthesis and don't have any homologues in humans. NMVA pathway is the only source of isoprenoids for certain eubacteria, parasite and plants. Absence of the NMVA pathway in higher organisms has opened a new platform for the development of …

A Case Study Of Perspectives On Building School And Community Partnerships, Myrna Lee Hogue

A strong partnership between a school and the surrounding community leads to school success. Schools can be more successful with community involvement and engagement than if functioning in isolation. Community engagement leads to greater academic achievement of students.

Utilizing qualitative case study methods, this study focused on the perspective of school and community partners on building relationships. The purpose of this study was to describe and explain selected participants' perspectives on how a school builds partnerships with the community. I studied the relationship between an elementary school and community partners that have been in existence for at least three years …

Temporal And Spatial Analysis Of Monogenetic Volcanic Fields, Koji Kiyosugi

USF Tampa Graduate Theses and Dissertations

Achieving an understanding of the nature of monogenetic volcanic fields depends on identification of the spatial and temporal patterns of volcanism in these fields, and their relationships to structures mapped in the shallow crust and inferred in the deep crust and mantle through interpretation of geochemical, radiometric and geophysical data.

We investigate the spatial and temporal distributions of volcanism in the Abu Monogenetic Volcano Group, Southwest Japan. E-W elongated volcano distribution, which is identified by a nonparametric kernel method, is found to be consistent with the spatial extent of P-wave velocity anomalies in the lower crust and upper mantle, supporting …

Interrogating Grenadian Masculinities And Violence Against Women: An Evaluation Of The United Nations Partnership For Peace Program, Rohan Dexter Jeremiah

USF Tampa Graduate Theses and Dissertations

This applied anthropology study, guided by a feminist perspective and in particular, Black Feminist Thought is an outgrowth of an evaluation study of the Partnership for Peace Program (PFP) in Grenada, West Indies. The PFP is a Caribbean-specific model that was built into a sixteen-week cycle program by the United Nations Entity for Gender Equality and Empowerment of Women (UNWomen). Since 2005, the PFP has been geared towards Grenadian men, who have used violence against women to express their masculine identities. PFP focuses exclusively on rehabilitating male perpetrators with a goal to protect the human rights of women. This research …

A Multilevel Analysis Of Institutional Fiscal Autonomy And Its Effect On Affordability, Operating Efficiency, And Minority Access At Public Colleges And Universities, Christine J. Glass

USF Tampa Graduate Theses and Dissertations

In recent years, an unstable funding environment for state higher education systems has led to a trend of increasing institutional fiscal autonomy in exchange for reductions in appropriations. With the growing concern that reducing state oversight will result in increased tuition and spending levels, this study was designed to provide a clearer understanding of how fiscal autonomy at public institutions impacts measures important to the state public policy goals of affordability, operating efficiency, and access. To accommodate the diversity and hierarchical structure of public institutions, this study used multilevel modeling techniques to integrate complex, interrelated institution- and state-level data. Institution-level …

Understanding Operating Speed Variation Of Multilane Highways With New Access Density Definition And Simulation Outputs, Bing Huang

USF Tampa Graduate Theses and Dissertations

Traffic speed is generally considered a core issue in roadway safety. Previous studies show that faster travel is not necessarily associated with an increased risk of being involved in a crash. When vehicles travel at the same speed in the same direction (even high speeds, as on interstates), they are not passing one another and cannot collide as long as they maintain the same speed. Conversely, the frequency of crashes increases when vehicles are traveling at different rates of speed. There is no doubt that the greater speed variation is, the greater the number of interactions among vehicles is, resulting …

Shaping Identity: Male And Female Interactions In Cinema, Jonette Lauren Lagamba

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Since the inception of cinema, women have been portrayed with the typical identities of emotionally and physically weak characters; this portrayal led to their subsequent dependence on men. Men were usually the protagonists and/or the heroes, following their archetypal journey. Thus, women's position in early cinema was to exemplify what men were not, placing the former in the diminutive position of the Other. One may conclude that men were often defined by what women lacked, and the women were defined by their relationships with these heroic men. As time progressed in the history of cinema, women's images retained part …

Algorithms For Visual Maritime Surveillance With Rapidly Moving Camera, Sergiy Fefilatyev

USF Tampa Graduate Theses and Dissertations

Visual surveillance in the maritime domain has been explored for more than a decade. Although it has produced a number of working systems and resulted in a mature technology, surveillance has been restricted to the port facilities or areas close to the coastline assuming a fixed-camera scenario. This dissertation presents several contributions in the domain of maritime surveillance. First, a novel algorithm for open-sea visual maritime surveillance is introduced. We explore a challenging situation with a camera mounted on a buoy or other floating platform. The developed algorithm detects, localizes, and tracks ships in the field of view of the …

Failed Heroes: Hypermasculinity In The Contemporary American Novel, Josef D. Benson

USF Tampa Graduate Theses and Dissertations

My study highlights a link of U.S. American hypermasculinity running through Cormac McCarthy's two novels Blood Meridian (1985) and All the Pretty Horses (1992), Toni Morrison's Song of Solomon (1977), and James Baldwin's Another Country (1960). My literary interpretations of these texts suggest that U.S. American hypermasculine man originated in the American frontier and transformed into a definition of hegemonic masculinity embraced by many southern rural American men. These southern rural American men then concocted the myth of the black rapist in order to justify the mass murder of African American men after Reconstruction, inadvertently creating a figure more hypermasculine …

Electronic Peer Feedback In A Collaborative Classroom, Cassandra A. Branham

USF Tampa Graduate Theses and Dissertations

This study examines the ways in which frequency and reflexivity affect student engagement with the peer feedback process. I study the peer e-feedback sessions conducted via My Reviewers in a pilot model of Composition 2 at a large research university in the southeast in order to determine if an increased focus on the peer feedback activity might enhance the effectiveness of the process. Through textual analysis and survey results, I determine that an increased focus on electronic peer feedback along with an increase in frequency and reflexivity helps to minimize some common criticisms of the peer feedback process. In this …

Choice, Management, & Modification: Situational Context In Risky Choice, Nathaniel K. Decker

USF Tampa Graduate Theses and Dissertations

We sought to examine the potential differences between different types of risky decisions. While some decisions are easily represented as choices between future alternatives, other decisions may be better represented as the management of a personally owned situation. Schneider (2003) created the risk management task, which manifested these situated improvement decisions, and identified a unique pattern of risk preferences when compared to the standard gambling paradigm. To determine what cognitive processes might be differentially activated for each type of decisions so as to yield these risk preference differences, we incrementally manipulated the gambling paradigm to parse potentially influential elements of …

Low Level Exposure To Air Pollution And Risk Of Adverse Birth Outcomes In Hillsborough County, Florida, Maria B. Mainolfi

USF Tampa Graduate Theses and Dissertations

In this retrospective cohort from 2002 through 2007, 104,003 singleton live births in Hillsborough County, Florida were analyzed to elucidate the relationship between feto-infant morbidity outcomes and prenatal exposure to six criteria air pollutants. This study is based on three linked databases: The Florida Hospital Discharge database; The vital statistics records of singleton live births; Air Pollution meteorological data from the Environmental Protection Agency. There are six common air pollutants, particulate matter 2.5 (PM2.5), particulate matter 10 (PM10), ground-level ozone (O3), carbon monoxide (CO), nitrogen (NOx), and lead (Pb). These pollutants are harmful to human health and the environment. The …

Plant Species Richness And Species Area Relationships In A Florida Sandhill, Monica Ruth Downer

USF Tampa Graduate Theses and Dissertations

Pine sandhill are integral pyrogenic communities in the southeastern United States. Though once widespread, habitat destruction, fire suppression and fragmentation have reduced the population to nearly 3%. It is important to learn as much as possible about these unique areas in order to implement best management practices to conserve and restore the existing populations of these communities.

Fire is central to the maintenance of pine sandhill communities and two conceptual hypothesis regarding burn frequency have come to light in maintaining the unique species composition and richness of these areas. The first is the Intermediate Disturbance Hypothesis which suggests that intermediate …

Assessing The Microbial Consequences Of Remediation: Surrogate Microbial Screening And Native Metabolic Signatures In Tc(Vii) Contaminated Sediments, Kathryn Lafaye Bailey

USF Tampa Graduate Theses and Dissertations

The chemical and physical processes controlling contaminant fate and transport in the vadose zone limit the options for application of many remedial technologies. Foam delivery technology (FDT) has been developed as a potential solution to overcome these limitations for remediating subsurface and deep vadose zone environments using reactive amendments. Although there are many advantages to utilizing FDT for treatment in the deep vadose zone, little information is available on how the addition of these surfactants and remedial amendments affect the indigenous microbial communities in the deep vadose zone as well as the impact of biological transformations of surfactant-based foams on …

Voces Fabuladas Contra Estatuas Míticas: Francisco Herrera Luque Y Su Aproximación Literaria A La Historia Venezolana, Juan Vicente Ayala

USF Tampa Graduate Theses and Dissertations

This thesis postulates the narrative of Venezuelan psychiatrist and novelist Francisco Herrera Luque as one that demystifies the official historical discourse of his nation.

Our argument is developed through a two-part analysis. First, we present and examine the author's characteristic method, one that he called "fabled history", and the way it deals with elements of Venezuela's historical past. Secondly, we analyze the way Herrera Luque, while crafting an undoubtedly historical narrative, also analyzes many elements of the Venezuelan idiosyncrasy and identity through the illustration of colonial life in the nation, in particular within the oligarchic social class known as mantuanos, …

USF Tampa Graduate Theses and Dissertations

This feminist oral history project located at the intersections of disability, feminist, body politics, and educational theory presents an analysis of three individual student narratives about their experiences with learning disabilities and learning differences (LD/Ds) at the high school and university levels. This thesis introduces students' accounts of their daily lives, pasts, personal views, experiences, and memories about having learning disabilities and learning differences into the existing scholarship on LDs and reveals how students' narrated experiences might shed light on the ways in which education might be reformed to better meet the needs of students like them. In response to …

Detecting Surface Oil Using Unsupervised Learning Techniques On Modis Satellite Data, Joshua Kidd

USF Tampa Graduate Theses and Dissertations

The release of crude oil or other petroleum based products into marine habitats can have a devastating impact on the environment as well as the local economies that rely on these waters for commercial fishing and tourism. The Deepwater Horizon catastrophe that started on April 20th 2010 leaked an estimated 4.4 million barrels of crude oil into the Gulf of Mexico over a 3 month period threatening thousands of species and crippling the gulf coast. The National Oceanic and Atmospheric Administration (NOAA) used several satellite remote sensing technologies to manually track and predict the extent and location of oil on …

More Than Words: Rhetorical Devices In American Political Cartoons, Lawrence Ray Bush

USF Tampa Graduate Theses and Dissertations

This thesis argues that literary theory applied to political cartoons shows that cartoons are reasoned arguments. The rhetorical devices used in the cartoons mimic verbal devices used by essayists. These devices, in turn, make cartoons influential in that they have the power to persuade readers while making them laugh or smile. It also gives examples of literary theorists whose works can be applied to political cartooning, including Frederick Saussure, Mikhail Bakhtin, and Wolfgang Iser. Not only do those theorists' arguments apply to text, they also apply to pictorial representations.

This thesis also discusses changes in the cartoon art form over …

Data were collected through interviews, participant observations, and class artifacts. The program by design and constituency was …

The Impacts Of Population Density, And State & National Litter Prevention Programs On Marine Debris, Melissa Rose Brogle

USF Tampa Graduate Theses and Dissertations

Marine debris is improperly disposed of solid waste, also called litter, which is deposited in the marine environment (NOAA, 2010). Litter prevention techniques such as fines, cleanups, incentives, and others, can help to decrease litter, and ultimately decrease marine debris. This research analyzed 2000 and 2010 International Coastal Cleanup (ICC) data obtained from The Ocean Conservancy to ascertain whether certain litter prevention techniques did reduce amounts and types of marine debris found in coastal areas. The litter prevention techniques analyzed included state bottle bills, voluntary monofilament fishing line recycling programs, and the Keep America Beautiful (KAB) cigarette butt litter prevention …

Critical Heat Stress Evaluation Of Two-Layer Clothing Ensembles And The Contributionof A Full-Face Negative Pressure Respirator, Oclla Michele Fletcher

USF Tampa Graduate Theses and Dissertations

Protective clothing ensembles are worn by workers as a barrier to chemical and physical hazards, but can restrict heat loss and increase worker heat stress. The question of whether a respirator adds to heat stress or strain burden is a continuing concern among occupational health professionals. The purpose of this study was to determine if there are differences in heat stress or strain among the current Toxicological Agent Protective (TAP) ensemble and two ensemble variations used in demilitarization of chemical weapons. Four acclimatized adult males wore five ensembles in a balanced design while walking in a climatic chamber at a …

The Impact Of Continuous And Discontinuous Cycle Exercise On Affect: An Examination Of The Dual-Mode Model, Sam Greeley

USF Tampa Graduate Theses and Dissertations

Low-volume, high-intensity interval training has been garnering attention in the exercise physiology literature recently due to its proposed time-efficiency. Also, recent work comparing continuous exercise to high-intensity interval training demonstrated superior ratings of perceived enjoyment following interval training. However, the dual-mode model suggests that exercise above ventilatory threshold (VT) done continuously will result in an almost homogenous decline in affect, which may reduce adherence.

Numerous studies confirm the dual-mode model's prediction of reduced affect when exercising above VT, but no research to date has applied the model's predictions to interval training. The purpose of this study was to examine the …

Assessing The Link Between Coastal Development And The Quality Of Fish Habitat In Mangrove Tidal Tributaries, Justin Micheal Krebs

USF Tampa Graduate Theses and Dissertations

To assess the potential influence of coastal development on the quality of estuarine habitat for nekton, we characterized land use and the intensity of land development surrounding small tidal tributaries of Tampa Bay. Based on this characterization, we classified tributaries as undeveloped, industrial, urban or man-made (i.e., mosquito-control ditches). Over one-third (37%) of tributaries were determined to be heavily developed, while fewer than one-third (28%) remain relatively undeveloped. We then examined the nekton community from eleven tributaries in watersheds representing the defined land-use classes. Whereas mean nekton density and species richness were both independent of land use, nekton-community structure differed …

Comparison Of Visual Vs. Microscopic Methods To Detect Blood Splatter From An Intravascular Catheter With Engineered Sharps Injury Protection (Esip), Aiysha R. Ansari

USF Tampa Graduate Theses and Dissertations

Intravascular devices with engineered sharps injury protection (ESIP) are designed to reduce sharps injuries, but have not been investigated for blood splatter potential. In this laboratory-based experiment, which did not use human subjects, 100 intravenous catheters of the same type with a retraction mechanism, were tested for blood splatter. Once blood was obtained from a simulated brachial vein containing mock venous blood, the devices were placed in a testing chamber and scientific filters labeled A, B & C were used to capture blood splatter after activation. The blood splatter was examined visually and microscopically, and the filters were weighed pre- …

Development And Application Of An F/M Based Anaerobic Digestion Model And The Rt-Ribosyn Molecular Biology Method, Matthew Raymond Cutter

USF Tampa Graduate Theses and Dissertations

A simple anaerobic digestion model has been developed for a continuously-stirred tank reactor (CSTR), which links the specific biogas production rate to the food/microorganism ratio (F/M). The model treats the various microbial populations involved in the sequential biological processes involved in anaerobic digestion as a composite and links the entire biomass specific growth rate directly to the specific biogas production rate. The model was calibrated by determining the specific gas production rate for a range of F/M values using a municipal wastewater seed sludge. The model predictions for steady-state biogas production rates were compared to observed biogas production and volatile …

Don't Blame It On My Ovaries: Exploring The Lived Experience Of Women With Polycystic Ovarian Syndrome And The Creation Of Discourse, Jennifer Lynn Ellerman

USF Tampa Graduate Theses and Dissertations

Polycystic Ovarian Syndrome (PCOS) is the most common endocrine disorder among females of childbearing age, affecting between 6-8% of the population. It is also the most common cause of infertility. Females with PCOS may have two or more of a constellation of symptoms that can potentially leave them at odds in terms of normative ideals of femininity. This study examines how feminist theory interrogates and analyzes knowledge about the body and PCOS, integrating the lived experiences of women to provide a deeper, more meaningful understanding of what it means to be a woman with PCOS.
