Molecular And Genomic Studies Of Temperate Phages From Halomonas Aquamarina And Bacillus Spp. Isolates From The Gulf Of Mexico, Jennifer M. Mobberley

USF Tampa Graduate Theses and Dissertations

Viruses are the most abundant biological entities in the ocean and are believed to contribute to nutrient cycling, bacterial diversity, and horizontal gene exchange. However, little is known about the relationship between temperate phages and their hosts in marine environments. In this thesis, phage-host systems from the Gulf of Mexico were used to study the influence of temperate phages in bacteria. PhiHAP-1 is a temperate myovirus induced with mitomycin C from Halomonas aquamarina isolate. The genome of this phage was 39,245 nucleotides long and contained 46 predicted genes. Besides genes involved in lysogeny, PhiHAP-1 contained a protelomerase, which is responsible …

Modulation Of Adult Neural Plasticity By Proteolytic Catabolism Of Lecticans, Joanne Mayer

USF Tampa Graduate Theses and Dissertations

The extracellular environment of the central nervous system (CNS) through which neuritic processes must traverse during development or after injury is complex, and may vary from stabile conditions to a milieu favorable for neural plasticity and growth. The extracellular space in the CNS accounts for about 20% of brain volume and is composed of aggregating complexes of several different extracellular matrix (ECM) molecules. The ECM supports neural networks and acts as a barrier for neurite extention, depending on the type of molecules involved and the various signals they induce. One mechansim that may produce an environment favoring plasticity is the …

Construction And Application Of Computationally Tractable Theories Of Nonlinear Spectroscopy, Christine L. Neipert

USF Tampa Graduate Theses and Dissertations

Nonlinear optical processes probe systems in unique manners. The signals obtained from nonlinear spectroscopic experiments are often significantly different than more standard linear techniques, and their intricate nature can make it difficult to interpret the experimental results. Given the complexity of many nonlinear lineshapes, it is to the benefit of both the theoretical and experimental communities to have molecularly detailed computationally amenable theories of nonlinear spectroscopy. Development of such theories, bench marked by careful experimental investigations, have the ability to understand the origins of a given spectroscopic lineshape with atomistic resolution. With this goal in mind, this manuscript details the …

Self Assembly Of Complex Structures, Michael Nellis

USF Tampa Graduate Theses and Dissertations

The state of the art in artificial micro self assembly concepts are reviewed. The history of assembly is presented with a comparison to macro assembly, which has been widely studied, and micro self assembly. Criteria were developed and tested to show that macro assembly is more complex in ways that micro self assembly is not. Self assembly requirements for successful and complex self assembly, which evolved from the macro and micro comparison, are also established and tested. A method to assemble complex structures in the micro scale is proposed and demonstrated at the meso scale. The basic concepts of self …

The Impact Of Fidelity And Innovations On Healthy Families America Programs, Ashley E. Nixon

USF Tampa Graduate Theses and Dissertations

Fidelity to a program model and innovations added to the program model have been found to positively impact large scale program expansion and implementation (Blakely et al., 1987). Research examining the effectiveness of Healthy Families America (HFA) programs has been hindered by the differences that exist among HFA programs. This study examines the impact program fidelity and innovations have on outcome measures of updated immunizations, primary medical care providers, and participant retention for 102 HFA sites. Factor analysis and regression were used to analyze archival data. Results indicate that fidelity was positively related to percentage of participants with updated immunizations …

Elisa Brune’S Le Goût Piquant De L’Univers: A Translation And Introduction, Ryan Orgera

USF Tampa Graduate Theses and Dissertations

Le Goût piquant de l'Univers is written by the Francophone Belgian writer Elisa Brune. Brune holds a Ph.D. in environmental sciences, and this novel does not stray far from her training in science. The setting of this oeuvre is that of a Provençal village of Peyresq, the premiere annual rendezvous for the world's foremost cosmologists. The vocabulary employed in this book is that of highly scientific coteries. The work's sentence structure is a mix of dialogue, and unruly compound phrases. These two aforementioned stylistic choices made the translation of this work especially difficult. In translating, I worked with Dr. Gaëtan …

Two Essays On Market Efficiency ⎯ Tests Of Idiosyncratic Risk: Informed Trading Versus Noise And Arbitrage Risk, And Agency Costs And The Underlying Causes Of Mispricing: Information Asymmetry Versus Conflict Of Interests, Jung Chul Park

USF Tampa Graduate Theses and Dissertations

I examine the informational efficiency of stock markets by testing the relation between idiosyncratic volatility and equity mispricing. I find that the level of mispricing declines with idiosyncratic volatility consistent with the notion that greater levels of firm-specific risk reflect greater participation of informed traders in the market for the stock. However, I also find that mispricing increases with idiosyncratic volatility for highly volatile stocks, and this is attributed to both noise trading and arbitrage risk. In addition, I investigate the link between agency costs and equity mispricing, and whether it exists due to information asymmetry or the degree of …

The Role Of Norepinephrine In Learning: Cerebellar Motor Learning In Rats, Daniel A. Paredes

USF Tampa Graduate Theses and Dissertations

Delay classical eyeblink conditioning is an important model of associative, cerebellar dependent learning. Norepinephrine (NE) plays a significant modulatory role in the acquisition of learning; other neurotransmitter systems are also at play. The goal of this dissertation was to determine whether NE, GABA and glutamate (Glu) release is observed in cerebellar cortex during delay eye blink conditioning, and whether such release was selectively associated with training and not due only to stimulatory sensory input. The data support the hypothesis of noradrenergic and GABAergic system involvement in motor learning with NE as a modulator of early responding and GABA as a …

An Exploration Of Three Residence Hall Types And The Academic And Social Integration Of First Year Students, Dorothy E. Paine

USF Tampa Graduate Theses and Dissertations

Living on campus has long been an important part of many students' collegiate experience. Most research describing the benefits of living on campus was conducted in the 1960s and 1970s and was based upon students living in double rooms on double loaded corridors with community bathrooms. In recent years, the style of residence hall buildings has changed from these traditional rooms to suite and apartment-style housing offering more privacy and greater amenities to students. This study sought to examine how first year students living in three different types of residence hall environments differ on measures of social and academic integration, …

Akt Function And Human Oncogenesis, Sungman Park

USF Tampa Graduate Theses and Dissertations

Accumulated evidence indicates that, by the phosphorylation of its physiological substrates, Akt promotes cell survival, proliferation and angiogenesis. While a number of Akt targets have been identified, the mechanism by which Akt regulates cell survival and growth and induces malignant transformation still remains elusive. During the last 5 years, I have shown that AKT1 cross-talks with Src/Stat3 pathway. AKT1 is a direct target gene of Stat3. Protein/mRNA levels and promoter activity of AKT1 are significantly induced by constitutively active Src and Stat3. Knockdown of Stat3 or dominant-negative Stat3 reduced AKT1 expression induced by constitutively active Src. Blockage of AKT1 expression …

Effects Of Corrosion On Steel Reinforcement, David Ostrofsky

USF Tampa Graduate Theses and Dissertations

Corroded steel in concrete is a structural issue that plaques concrete structures in coastal regions. Traditionally corroded steel strength is calculated from a distributed area loss due to corrosion over the entire surface of the steel and reducing the capacity accordingly. In reality, corrosion attacks localized regions creating pits and reducing the cross section in a small region which amplifies the effects of corrosion. Stress concentrations at the corrosion pitting damage may further reduce the tensile capacity of the steel. A study of corrosion damage and strength associated with pitting damage can assist in understanding the ultimate tensile capacity of …

Documenting Dylan: How The Documentary Film Functions For Bob Dylan Fans, Theodore G. Petersen

USF Tampa Graduate Theses and Dissertations

The purpose of this study is to explore the role of the documentary film in the relationship between the artist and the fan; specifically how Bob Dylan fans use the documentary films Dont Look Back, directed by D.A. Pennebaker, and No Direction Home, directed by Martin Scorsese. Dylan, Pennebaker, and Scorsese are three important figures in American popular culture, and these are the two most prominent films about Dylan. These films discuss relatively the same time period, yet delineate two different versions of Dylan's identity. Dont Look Back, released in 1967, documents Dylan's 1965 tour of England. Because of Pennebaker's …
