Modeling And Experimentation Of Micro-Scale Self-Assembly Processes, Gary Hendrick

USF Tampa Graduate Theses and Dissertations

Self-Assembly in the context of micro-scale integration refers to a developing set of techniques which exploit phenomena resulting in the spontaneous integration of micro-scale components into designed systems. Self-Assembly may be leveraged most effectively in parallel assembly processes. This thesis studies the modeling of micro-scale self-assembly processes as stochastic processes. The researchers propose that self-assembly processes may be modeled as Markov chains. In order to develop these models a Self-Assembly test system was created and trials were conducted using this system. Initial tests into the hypothesis that variables contributing to the transition probabilities include the kinetic energy of the assembly …

Fluorescence Molecular Tomography: A New Volume Reconstruction Method, Stephen Joseph Shamp

USF Tampa Graduate Theses and Dissertations

Medical imaging is critical for the detection and diagnosis of disease, guided biopsies, assessment of therapies, and administration of treatment. While computerized tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), and ultra-sound (US) are the more familiar modalities, interest in yet other modalities continues to grow. Among the motivations are reduction of cost, avoidance of ionizing radiation, and the search for new information, including biochemical and molecular processes. Fluorescence Molecular Tomography (FMT) is one such emerging technique and, like other techniques, has its advantages and limitations. FMT can reconstruct the distribution of fluorescent molecules in vivo using near-infrared …

USF Tampa Graduate Theses and Dissertations

This study explored the current role of school psychologists in the provision of school-based mental health services, including factors that relate to their provision of such services, by surveying a national sample of practicing school psychologists. Despite an extensive knowledge base regarding which professional services school psychologists provide in general, few studies have focused exclusively on specific modalities of mental health services. Previous lines of research also have not fully identified why school psychologists do not spend as much of their professional time in the provision of mental health services as they would desire. Therefore, a central purpose of this …

The Novel Use Of Recombinant Granulocyte-Macrophage Colony-Stimulating Factor (Gm-Csf) To Reverse Cerebral Amyloidosis And Cognitive Impairment In Alzheimer’S Disease Mouse Models: Insights From The Investigation Of Rheumatoid Arthritis As A Negative Risk Factor For Alzheimer’S Disease, Timothy David Boyd

USF Tampa Graduate Theses and Dissertations

For many years, it has been known that Rheumatoid arthritis (RA) is a negative risk factor for the development of Alzheimer’s disease (AD). It has been commonly assumed that RA patients’ usage of non-steroidal anti-inflammatory drugs (NSAIDs) have helped prevent the onset and progression of AD pathogenesis. Furthermore, experiments in animal models of Alzheimer’s disease have looked to inhibit inflammation, and have demonstrated some efficacy against AD-like pathology in these models. Thus many NSAID clinical trials have been performed over the years, but all have proven unsuccessful in AD patients. This suggests that intrinsic factors within RA pathogenesis itself may …

The Accidental Practitioner: Principles Of Rational Emotive Behavior Therapy In The Works Of Kurt Vonnegut, Joseph J. Ward

USF Tampa Graduate Theses and Dissertations

Just as psychology and philosophy have influenced the field of literary studies, literature provides insight about the theories and practices of its sister disciplines. The purpose of this thesis is to demonstrate how literary works of Kurt Vonnegut illuminate principles of the influential branch of psychotherapy known as Rational Emotive Behavior Therapy (REBT).

This thesis traces the similar philosophies and shared beliefs of Vonnegut and REBT's founder, Albert Ellis, and details how Ellis's REBT is illustrated in selected works of Vonnegut, specifically, Slaughterhouse-Five, Breakfast of Champions, Galapagos, and Timequake. The thesis concludes by suggesting that Vonnegut's …

Tracking Chemistry Self-Efficacy And Achievement In A Preparatory Chemistry Course, Carmen Alicia Garcia

USF Tampa Graduate Theses and Dissertations

Self-efficacy is a person's own perception about performing a task with a certain level of proficiency (Bandura, 1986). An important affective aspect of learning chemistry is chemistry self-efficacy (CSE). Several researchers have found chemistry self-efficacy to be a fair predictor of achievement in chemistry. This study was done in a college preparatory chemistry class for science majors exploring chemistry self-efficacy and its change as it relates to achievement. A subscale of CAEQ, Chemistry Attitudes and Experiences Questionnaire (developed by Dalgety et al, 2003) as well as student interviews were used to determine student chemistry self-efficacy as it changed during the …

Malaria In Prehistoric Sardinia (Italy): An Examination Of Skeletal Remains From The Middle Bronze Age, Teddi J. Setzer

USF Tampa Graduate Theses and Dissertations

Sardinia was an island with a history of a malarious environment until eradication efforts were conducted from 1946 to 1950. While historic documents suggest the disease was introduced from North Africa around 500 BC, no study has been conducted to test for the presence of malaria in prehistoric native populations, such as the Nuragic people of the Bronze Age. However, it has been suggested that aspects of the Nuragic culture, for example the stone structures found throughout the island, are adaptations to a malarious environment. The purpose of this dissertation is to test the hypothesis that malaria was present in …

An Ecology Of Performance: Gregory Bateson's Cybernetic Performance, Daniel Matthew Blaeuer

USF Tampa Graduate Theses and Dissertations

This dissertation is a case study of the public performances of Gregory Bateson at The Esalen Institute. The case study is a reconsideration of the work of Gregory Bateson from the perspective of performance studies. The author brings together performativity, cybernetics, and the sacred to argue that Gregory Bateson, in his public performances, was striving for grace in encounters with others. The author has conducted archival research into Bateson’s presentations and has spoken with several close to Bateson to get a sense of how his process of public presentation paralleled his ideas—a process of continually working through ideas in conversation …

The Aggregated Influences Of Poverty Impacting Dental Care Access And Oral Health Among Migrant Farmworkers In Tampa, Florida, Nolan Kline

USF Tampa Graduate Theses and Dissertations

Oral health is an important aspect of overall health, but many vulnerable populations such as migrant farmworkers are without access to oral healthcare. Although some non-government organizations such as faith-based organizations have attempted to fill gaps left by government and private sectors, a lack of a dental safety net creates limited access to oral health services for migrant farmworkers. Access to care is further constrained by structural factors including low wages, migration route, and high costs of care. Building off a critical medical anthropology approach in understanding oral healthcare access, I argue that limited oral health access for migrant workers …

An Integrated Building Water Management Model For Green Building, Caryssa Joustra

USF Tampa Graduate Theses and Dissertations

The U.S. Green Building Council (USGBC) is the developer of the Leadership in Energy and Environmental Design (LEED™) green building scoring system. On first inspection of LEED points, few address water efficiency. However, water management encompasses other points beyond the Water Efficiency (WE) category. In general, the industry is apt to take a somewhat compartmentalized approach to water management. The use of alternative water sources or the reuse of wastewater significantly complicates the water budget picture. A total water management systems approach, taking into consideration water from various sources, both inside and outside the building, should be implemented in order …

Volume Phase Transitions In Surface-Tethered, Photo-Cross-Linked Poly(N-Isopropylacrylamide) Networks, Ajay Kumar Vidyasagar

USF Tampa Graduate Theses and Dissertations

The overall thrust of this dissertation is to gain a comprehensive understanding over the factors that govern the performance and behavior of ultra-thin, cross-linked polymer films. Poly(NIPAAm) was used as a model polymer to study volume phase transition in surface tethered networks.

Poly(NIPAAm) undergoes a reversible phase transition at approximately 32°C between a swollen hydrophilic random coil to a collapsed hydrophobic globule state, thought to be caused by increased hydrophobic attractions between the isopropyl groups at elevated temperatures. We present a simple photochemical technique for fabricating structured polymer networks, enabling the construction of responsive surfaces with unique properties. The approach …

The Relationship Between Fam5c Snp (Rs10920501) Variability, Metabolic Syndrome, And Inflammation, In Women With Coronary Heart Disease, Jennifer L. Cline

USF Tampa Graduate Theses and Dissertations

The leading cause of death among women is coronary heart disease (CHD), a multifactorial disease with polygenic heritability estimated at 50%. Polymorphisms in the family with sequence similarity 5, member C' (FAM5C) gene have been associated with myocardial infarction (MI), and one single-nucleotide polymorphism (SNP) has partially accounted for linkage in an acute coronary syndrome subset. The linkage peak on FAM5C corresponds directly with a quantitative trait locus for the inflammatory biomarker monocyte chemoattractant protein 1, as well as a linkage peak to metabolic syndrome (MetS). Metabolic syndrome increases the risk of developing CHD, and MI has been …

Maintaining Biodiversity With A Mosaic Of Wetlands: Factors Affecting Amphibian Species Richness Among Small Isolated Wetlands In Central Florida., Jackie Guzy

USF Tampa Graduate Theses and Dissertations

The biodiversity value of a wetland is linked not only to its position in the landscape relative to other wetlands, but also to its habitat characteristics. I monitored amphibian species richness among 12 small, isolated, and undisturbed wetlands (which occur on lands permitted for phosphate mining) in central Florida during the 2005 and 2006 breeding seasons. I used seven habitat and landscape variables to characterize the environments of the wetlands and generalized linear models to determine which of these variables had the greatest influence on the occurrence of seven amphibian species (Anaxyrus terrestris, Gastrophryne carolinensis, Hyla gratiosa …

Gold Nanoparticles And Their Polymer Composites: Synthesis Characterization And Applications, Nidhi Joshi

USF Tampa Graduate Theses and Dissertations

Gold nanoparticles are excellent candidates for all the biomedical applications due to their size and shape dependent optical and physiological properties. In this study, gold nanoparticles were synthesized chemically for bio-application. It was observed that the size and shape of gold nanoparticles depend strongly on the concentration of chemical solution, type of reducing agent used in the reaction, temperature of the solution and stabilizing agent for reaction. Transmission electron microscopy (TEM) has been used extensively to determine the size and shape of the gold nanoparticles. Optical properties of the size and shape selected nanoparticles were studied using UV-vis spectrophotometer in …

Electrospinning Protein Nanofibers To Control Cell Adhesion, Cynthia Chinwe Nwachukwu

USF Tampa Graduate Theses and Dissertations

The structural and mechanical properties of a surface often play an integral part in the determination of the cell adhesion strength and design parameters for creating a biodegradable electrospun scaffold. Nanofibers composed of the globular proteins bovine serum albumin (BSA) and fibronectin were produced by electrospinning with the electrospun protein scaffold serving as an extracellular matrix to which adhesion interaction will exist with cells via cell surface integrin. This interaction is vital in regulation cell differentiation, growth and migration and cell adhesion.

We will demonstrate the ability to manipulate ligand-receptor interaction, the properties of the electrospun fibers, control and the …

Synthesis, Characterization, And Self-Assembly Of Gold Nanorods And Nanoprisms, Kristina L. Tran

USF Tampa Graduate Theses and Dissertations

The unique properties of gold nanoparticles make them excellent candidates for applications in electronics, sensing, imaging, and photothermal therapy. Though abundant literature exists for isotropic gold nanoparticles, work on nanoparticles of different shapes has been gaining interest recently. Anisotropic gold nanoparticles, such as nanorods and nanoprisms, have tunable optical properties in the visible and near-infrared regions. Through synthesis and surface modification, the production of various shapes of these gold nanoparticles can be controlled to meet different applications.

Two different types of gold nanorods were used in this thesis. The first type was stabilized with cetyltrimethylammonium bromide (CTAB) and had aspect …

Foraging Decisions Of Nocturnal Mice Under Direct And Indirect Cues Of Predation Risk, Robbin G. Capers

USF Tampa Graduate Theses and Dissertations

The perception of increased predation risk by nocturnal mice and other small mammals has been shown to reduce activity levels, particularly in foraging effort. Various cues of predation risk have been used in previous studies, but few have assessed the potential interactions between different types of cues. I conducted field, laboratory, and enclosure experiments using predator scents, artificial light, and microhabitat variables to determine the effects of direct and indirect cues of predation risk on foraging behavior in wild nocturnal mice. Experimental foraging trays served as artificial resource patches, and giving-up densities were measured in order to test for foraging …

Synthesis And Characterization Of Novel Nanomaterials: Gold Nanoshells With Organic- Inorganic Hybrid Cores, Alisha D. Peterson

USF Tampa Graduate Theses and Dissertations

Gold nanoshells, a material generally composed of a core of silica surrounded by

a thin shell of gold, are of great interest due to their unique and tunable optical properties.

By varying the shell thickness and core size, the absorption and scattering properties are

greatly enhanced. The nanoshells can be made to absorb or scatter light at various

regions across the electromagnetic spectrum, from visible to the near infrared. The

ability to tune the optical properties of nanoshells allows for their potential use in many

different areas of research such as optical imaging, tumor ablation, drug delivery, and

Help-Seeking And Utilization Patterns Among African American And Caucasian Mothers And Fathers: An Examination Of Parental Problem Recognition, Barriers, And Beliefs, Idia Binitie Thurston

USF Tampa Graduate Theses and Dissertations

The underutilization of mental health services is a pervasive problem that persists despite efforts by researchers and interventionists to make treatment accessible. Several factors have been hypothesized to contribute to these underutilization rates including sociopolitical factors (financial and structural barriers), and cultural/familial factors (race, ethnicity, socioeconomic status, gender, age, marital status, attitudes, beliefs, and stigma). The current study set out to explore patterns of child mental health service utilization based on parents' perceptions. Guided by "The Youth Help-Seeking and Service Utilization Model," the relationship between parental problem recognition and willingness to seek formal and informal help as influenced by parents' …

Experimental Translocation Of The Florida Sand Skink (Plestiodon [=Neoseps] Reynoldsi): Success Of A Restricted Species Across Diverse Microhabitats, Nicholas Paul Osman

USF Tampa Graduate Theses and Dissertations

The fossorial Florida Sand Skink (Plestiodon [=Neoseps] reynoldsi) inhabits a restricted range of scrub and sandhill fragments on the ridges of central Florida. The high rate of urban and agricultural development in this area necessitates conservation strategies other than land acquisition and management because of the limited remaining Florida Sand Skink habitat available. This study tests the viability of translocation as a conservation strategy for this species and assesses which features of a recipient site contribute to the successful establishment of a population. In 2007, 300 individuals were collected and moved from an intact scrub habitat, …

Hydric Life: A Nietzschean Reading Of Postcolonial Communication, Elena F. Ruiz-Aho

USF Tampa Graduate Theses and Dissertations

This dissertation addresses the question of marginalization in cross-cultural communication from the perspectives of hermeneutic philosophy and postcolonial theory. Specifically, it focuses on European colonialism‘s effect on language and communicative practices in Latin America. I argue colonialism creates a deeply sedimented but unacknowledged background of inherited cultural prejudices against which social and political problems of oppression, violence and marginalization, especially towards women, emerge—but whose roots in colonial and imperial frameworks have lost transparency. This makes it especially difficult for postcolonial subjects to meaningfully express their own experiences of psychic dislocation and fragmentation because the discursive background used to communicate these …

Regulatory Mechanism Of Myeloid Derived Suppressor Cell Activity, Cesar Alexander Corzo

USF Tampa Graduate Theses and Dissertations

Myeloid-derived suppressor cells (MDSC) are a major component of the immune suppressive network that develops during cancer. MDSC down-regulate immune surveillance and antitumor immunity and facilitate tumor growth. The ability of MDSC to suppress T cell responses has been documented; however the mechanisms regulating this suppression remain to be understood. This work proposes a biological dichotomy of MDSC regulated by the tumor microenvironment. In peripheral lymphoid organs MDSC cause T-cell non-responsiveness that is antigen-specific. These MDSC have increased expression of NOX2, enabling them to produce large amounts of reactive oxygen species. Since the transcription factor STAT3 is substantially activated in …

An Iterative Feature Perturbation Method For Gene Selection From Microarray Data, Juana Canul Reich

USF Tampa Graduate Theses and Dissertations

Gene expression microarray datasets often consist of a limited number of samples relative to a large number of expression measurements, usually on the order of thousands of genes. These characteristics pose a challenge to any classification model as they might negatively impact its prediction accuracy. Therefore, dimensionality reduction is a core process prior to any classification task.

This dissertation introduces the iterative feature perturbation method (IFP), an embedded gene selector that iteratively discards non-relevant features. IFP considers relevant features as those which after perturbation with noise cause a change in the predictive accuracy of the classification model. Non-relevant features do …

The efficiency to improve the water quality of industrial and municipal wastewater in a constructed wetland/filter basin treatment system was investigated. The wetland system was constructed in a closed phosphate mine used for clay settling and sand tailings in Polk County, Florida. During 18-months of monitoring the chemical/microbiological composition of treated wetland water remained relatively constant, despite significant seasonal variations in temperature, rainfall and humidity. The following changes in water quality between input and output were observed: substantial decrease of water temperature (up to 10°C), reduction of As, SO₄, F, Cl, NO₃, NO₂, Br, …

Increasing Healthy Food Choices In Preschoolers Using Correspondence Training And Recruiting Natural Communities Of Reinforcement, Elyse D. Wiseman

USF Tampa Graduate Theses and Dissertations

Obesity is a contributing factor to many diseases. Unhealthy food choices are a behavior that can lead to obesity. Teaching children to make healthy food choices at an early age could lead to healthy food choices throughout a lifetime, which would mitigate potential for obesity. A number of different treatments have evaluated healthy food choices in children; however, many did not evaluate or show maintenance effects. The purpose of this study was to utilize correspondence training to acquire healthy food choices in preschoolers and to evaluate of natural communities of reinforcement as a maintenance procedure. Results showed that correspondence training …

A Canine Audience: The Effect Of Animal-Assisted Therapy On Reading Progress Among Students Identified With Learning Disabilities, Julie Omodio Griess

USF Tampa Graduate Theses and Dissertations

This study explored the use of animal-assisted therapy with students identified with a learning disability and limited reading success. Initially, reading progress was defined as the participants' comprehension rate obtained from an oral Informal Reading Inventory (IRI) passage. The nature of the Informal Reading Inventory requires the introduction of more difficult reading passages as the student's comprehension rate increases, potentially masking the overall effect of the intervention. Due to this factor and erratic student performance, which is a common characteristic of students with learning disabilities, obtaining consistent comprehension rates was difficult. Therefore, progress was defined only as total amount of …
