A Comparative Study Of The Plants Used For Medicinal Purposes By The Creek And Seminoles Tribes, Kimberly Hutton

USF Tampa Graduate Theses and Dissertations

Previous studies in Native American ethnobotany on the shared use of medicinal and cultural plants between communities fail to clearly reveal if these shared uses are part of changing culture or remain a stabilizing connection between old and new tribes. During the late 1700's to early 1800's, various factions of the Creek tribes of Georgia migrated into Florida, forming a new tribe called the Seminoles. This event provides the unique opportunity to study the changing cultural and medicinal uses of plants by a new tribe in a new geographic location, revealing if cultural purposes were passed from one group to …

Differentiation Of Labor-Related Activity By Means Of Musculoskeletal Markers, Annette Doying

USF Tampa Graduate Theses and Dissertations

This study tests whether musculoskeletal markers are attributable to occupational categories. It is hypothesized that individuals over the age of 30 years with a lifetime occupation as a laborer will demonstrate a significantly different pattern of activity markers from individuals in the white collar classifications. A sample of n=69 from the Maxwell Museum's Documented Skeletal Collection are investigated.

Upper and lower extremities were scored for MSM type (robusticity, stress lesions, and ossification exostoses) and severity (grades 0 - 3) following Hawkey and Merbs (1995) visual reference system. To evaluate methodological approaches to MSM scoring, ossification exostoses and stress lesions were …

Improved Methodologies For Modeling Storage And Water Level Behavior In Wetlands, Kenneth Allan Nilsson

USF Tampa Graduate Theses and Dissertations

Wetlands are important elements of watersheds that influence water storage, surface water runoff, groundwater recharge/discharge processes, and evapotranspiration. To understand the cumulative effect wetlands have on a watershed, one must have a good understanding of the water-level fluctuations and the storage characteristics associated with multiple wetlands across a region. An improved analytical method is presented to describe the storage characteristics of wetlands in the absence of detailed hydrologic and bathymetric data. Also, a probabilistic approach based on frequency analysis is developed to provide insight into surface and groundwater interactions associated with isolated wetlands. The results of the work include: 1) …

Metal-Organic Materials: From Design Principles To Practical Applications, Mohamed H. Alkordi

USF Tampa Graduate Theses and Dissertations

The works presented herein outline rational design approaches towards construction of solid state materials with great potentials to answer some of current demanding applications. Specifically, the materials targeted are metal−organic materials with desirable structural features and functional properties. Metal−organic materials are constructed from organic linker molecules and metal ions under relatively mild solvothermal reaction conditions that preserve the structural features of the relatively simple building blocks. Therefore, it is feasible to conceive a retrospective pathway of the reaction and thus deconstruct the desirable structures into simple, chemicallyrelevant, building blocks in an approach known as the molecular building block approach. Due …

A Potential Tumor Suppressive Role Of Sirt1 In Cancer, Neha Kabra

USF Tampa Graduate Theses and Dissertations

The NAD-dependent deacetylase SIRT1 regulates several factors involved in stress response and cell survival but its function in cancer is largely unknown. Research suggests that SIRT1 influences several transcription factors and molecules that are important components of pathways often deregulated in cancer. Our experiments have shown that SIRT1 knock down by short hairpin RNA accelerates tumor xenograft formation by HCT116 colon cancer cells, whereas SIRT1 overexpression inhibits tumor formation. We have also found that, pharmacological inhibition of SIRT1 stimulates cell proliferation under conditions of growth factor deprivation suggesting a tumor suppressive function of SIRT1. Paradoxically, SIRT1 inhibition sensitizes the same …

Evaluation Of Behavioral Skills Training For Teaching Functional Assessment And Treatment Selection Skills To Parents, Rachel K. Graves

USF Tampa Graduate Theses and Dissertations

There have been many studies on teaching behavior analytic skills to parents for addressing problem behavior exhibited by their children. However, very few studies have addressed the issue of teaching parents to conduct a functional assessment and design a treatment for the problem behavior. The present study utilized behavioral skills training to teach parents how to conduct ABC recording, write a summary statement based on the data collected, and determine the proper treatment choices. The 8 participants participated in one 3 hour class in which a trainer used instructions, modeling, rehearsal, and feedback to teach these three skill sets. Prior …

The Life History And Energy Budget Of Hippocampus Erectus In Tampa Bay, Florida, Nicole M. Dunham

USF Tampa Graduate Theses and Dissertations

Seahorses, genus Hippocampus erectus, are subject to large and continuously-growing international trade. Concerns with the effects of trade on seahorse population worldwide have led to their international protection by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). In order to manage seahorse populations, we first need to understand their basic biology. The purpose of this project was to establish an energy budget for Hippocampus erectus from Tampa Bay, Florida. A total of 108 specimens were collected throughout Tampa Bay from 2004 to 2007 using 21.3 m offshore seines and 6.1 m otter trawls. …

Passive Acoustic Studies Of Estuarine Fish Populations Of Southwest Florida, James Vincent Locascio

USF Tampa Graduate Theses and Dissertations

Recordings of fish sound production were made in Charlotte Harbor, Florida using Long Term Acoustic Recording Systems (LARS) programmed to record 10 seconds of sound every 10 minutes. Results demonstrated a strong circadian pattern in fish sound production that occurred within a few hours of dusk each evening. Sound production lasted on average 8.7 hrs each evening during the peak spawning season. LARS were deployed when Hurricane Charley crossed Charlotte Harbor in August, 2004. The hurricane did not inhibit nightly chorusing events of spawning fish. Rather, sound levels produced by spawning fish on the night of and 3 days after …

The Fanconi Anemia (Fa)/Brca Dna Damage Repair Pathway Is Regulated By Nf-Κb And Mediates Drug Resistance In Multiple Myeloma, Danielle N. Yarde

USF Tampa Graduate Theses and Dissertations

The Fanconi Anemia (FA)/BRCA DNA damage repair pathway plays a critical role in the cellular response to stress induced by DNA alkylating agents and greatly influences drug response in cancer treatment. We recently reported that FA/BRCA DNA damage repair pathway genes are overexpressed and causative for resistance in multiple myeloma (MM) cell lines selected for resistance to melphalan. We hypothesized that the FA/BRCA DNA damage repair pathway mediates response and resistance to chemotherapeutic agents used to treat multiple myeloma and other cancers, and targeting this pathway is vital to overcoming drug resistance. In this dissertation, we show that FA/BRCA pathway …

Properties Of Carbon Nanotubes Under External Factors: Adsorption, Mechanical Deformations, Defects, And External Electric Fields, Yaroslav Shtogun

USF Tampa Graduate Theses and Dissertations

Carbon nanotubes have unique electronic, optical, mechanical, and transport properties which make them an important element of nanoscience and nanotechnology. However, successful application and integration of carbon nanotubes into new nanodevices requires fundamental understanding of their property changes under the influence of many external factors. This dissertation presents qualitative and quantitative theoretical understanding of property changes, while carbon nanotubes are exposed to the deformations, defects, external electric fields, and adsorption. Adsorption mechanisms due to Van der Waals dispersion forces are analyzed first for the interactions of graphitic materials and biological molecules with carbon nanotubes. In particular, the calculations are performed …

Many environmental organizations are starting to use color to generate awareness and create symbolic color associations. Based on the congruency theory and the elaboration likelihood model, this study tested specific research hypotheses pertaining to the effects of color-cause congruency and involvement with the cause on consumer reactions through a controlled experiment. Results reveal that involvement and the congruency between color and cause had an effect on attitude toward the organization and attitude toward the …

Priming Expectancies: Effects On Neurophysiological Indices Of Expectancy Violations And Drinking Behavior, Tyler Brumback

USF Tampa Graduate Theses and Dissertations

Investigations of the anticipated effects of alcohol indicate that cognitive frameworks are highly correlated with drinking and other variables associated with alcohol use, explaining up to 50% of the variance in drinking outcomes (Goldman, Darkes, & Del Boca, 1999; Goldman, 2002; Goldman et al., 2006; Goldman, Reich, & Darkes, 2006). Furthermore, alcohol expectancies appear to mediate the relationship between a variety of risk factors, such as sensation seeking, and alcohol outcomes (Darkes, Greenbaum, & Goldman, 2004). The current study examined the relationship of these cognitive networks with a physiological index of expectancy violation

Participants were presented with statements reflecting a …

Assessing The Effectiveness Of The Roaring Branch Bmp Retrofit Using Macroinvertebrate Bioassessment, James L. Banning

USF Tampa Graduate Theses and Dissertations

Using benthic macroinvertebrates to measure stream health has been widely used and accepted around the world. Macroinvertebrates are resident monitors of chronic impairment in a stream since they are relatively sessile and most commonly respond to disturbance by drift but can recolonize a restored stream reach very quickly. This study tested the effectiveness of macroinvertebrate metrics developed through the Rapid Bioassessment Protocol (RBP) to detect changes in stream integrity as the result of placement of a best management practice (BMP), installed on a tributary of Roaring Branch, located in Columbus, Georgia. The BMP was designed to attenuate flow to reduce …

An Exploratory Study Of The Intrapersonal, Socio-Cultural, And Behavioral Factors That Influence Hiv Risk Behaviors Among Ethnic Subgroups Of Black Heterosexual Men: The Intersection Of The Beliefs And Perceptions Of Black Women, Shalewa Noel-Thomas

USF Tampa Graduate Theses and Dissertations

Twenty five years after AIDS was first scientifically described, the disease continues to take its toll on the human population. HIV/AIDS disproportionately affects marginalized groups such as poor, underserved, minority populations. In the United States, Blacks become infected with and die from HIV/AIDS more than any other ethnic or racial group. Despite a vast body of literature on HIV/AIDS, little research has focused on black heterosexual men and even fewer studies have explored the context of risk among subgroups of black men.

Using qualitative research methods and a socio-ecological framework, this study explored the intrapersonal, socio-cultural, and behavioral factors that …

On The Involvement Of The Low-Density Lipoprotein Receptor In The Pathogenesis And Progression Of Alzheimer’S Disease, Jose Francisco Abisambra Socarras

USF Tampa Graduate Theses and Dissertations

Alzheimer's disease (AD) is the most prevalent form of age-associated dementia. Cholesterol dysregulation is linked with AD onset. Besides age, the most important risk factor associated with AD is the inheritance of the epsilon-4 allele of apolipoprotein E, a cholesterol transporter. In addition, while hypercholesterolemia has been shown to be an independent risk factor for AD, the nature of the cholesterol-AD link is still not clear. This gap in our understanding is partly due to a lack of knowledge about cholesterol metabolism in the central nervous system (CNS).

The low-density lipoprotein receptor (LDLR) is the main receptor of apoE and …

The Security And Foreign Policy Of The Islamic Republic Of Iran: An Offensive Realism Perspective, Bledar Prifti

USF Tampa Graduate Theses and Dissertations

This study argues that security and foreign policy of the Islamic Republic of Iran is mainly driven by the main principles of the Offensive Realism theory of international relations. While the Iranian political system is considered a theocratic system, based on the Islamic Shi'a ideology, its survival is defined as the ultimate ideology-an ideology that is paramount to any other ideology. Iran's security and foreign policy is determined and shaped by its need to survive in an anarchic international system. Iran's cooperation with "two Satans", Israel and the United States, during the Iran-Iraq war demonstrates that the ultimate ideology of …

Stat3 Contributes To Resistance Towards Bcr-Abl Inhibitors In A Bone Marrow Microenvironment Model Of Drug Resistance In Chronic Myeloid Leukemia Cells, Nadine N. Bewry

USF Tampa Graduate Theses and Dissertations

Imatinib mesylate (imatinib) represents a potent molecularly targeted therapy against the oncogenic tyrosine kinase, BCR-ABL. Although imatinib has shown considerable efficacy against chronic myeloid leukemia (CML), displaying high rates of complete hematological and complete cytogenetic responses, treatment with imatinib is not curative and overtime advanced-stage CML patients often become refractory to further treatment. Acquired resistance to imatinib has been associated with mutations within the kinase domain of BCR-ABL, BCR-ABL gene amplification, leukemic stem cell quiescence as well as over-expression of the multidrug resistance (MDR1) gene. However, in vitro resistance models often fail to consider the role of the tumor microenvironment …

Dyna-Mod Constructing The Modern Adaptable Home, Sarah Deardorff

USF Tampa Graduate Theses and Dissertations

The modern home has become a static fixture in society that is not reflected in the growing populous that is becoming an ever increasing mobile society. Many are not able to stay to the same place that they call home for long periods of time. Changing jobs, markets and neighborhoods force those to continue their movement around leaving what it is that they call their home to try and reproduce it within another location. The home finds itself lost in this transition and must now function on a greater adaptability than ever before and reflect the growing demand placed upon …

Striving And Surviving: The Phenomenology Of The First-Year Teaching Experience, Michael D. Smith

USF Tampa Graduate Theses and Dissertations

Despite the enduring relative popularity of teaching as a career, the research literature on teacher preparation suggests that there is growing concern about the state of the field. With each passing year, the demographic realities within k-12 classrooms bring new challenges for the teacher preparation enterprise. Shortages in high need communities and increasing numbers of provisionally certified (or uncertified) teachers represent two areas of concern. Notwithstanding the extraordinarily increasing cultural and linguistic diversity now found among the student population, the teacher population has failed to diversify in kind. The number of new teachers who are ill-prepared to respond to this …

Non-Calanoid Copepods At The Bermuda Atlantic Time-Series Study (Bats) Station: Community Structure And Ecology, 1995-1999, Hussain Ali Al-Mutairi

USF Tampa Graduate Theses and Dissertations

Zooplankton were sampled on a monthly basis at the Bermuda Atlantic Time-series Study (BATS) site from January 1995 to December 1999. Samples were collected using a 1-m², 200 µm mesh net. The net sampled the water column in an oblique manner from the surface to a mean depth of 200 m. One day and one night tow from each cruise was examined microscopically to determine the community structure of the non-calanoid copepods. In addition, a three year set of nighttime samples were examined taken by 0.5-m², 20 and 35 µm mesh nets (1995-1996 and 1997, respectively) towed obliquely to 150 …

Frozen Assets: Science, Natural Philosophy, And The Quest For Arctic Gold, Justin V. Castells

USF Tampa Graduate Theses and Dissertations

This paper looks at the emerging conflict between natural philosophy and empirical science in the late sixteenth century by examining the events surrounding the supposed discovery of gold in northern North America by Martin Frobisher in 1577. The discovery of gold in a region thought incapable of producing the metal, and the subsequent assays of ore mined from that region served as a catalyst for conflict between different understandings of the natural world. Proponents of natural philosophy and empirical science each used their theoretical tools to prove or disprove the value of the ore, reflecting the larger discussions taking place …

Spatial And Temporal Trends In Water Quality In The Alafia River Watershed, Jennifer M. Aragon

USF Tampa Graduate Theses and Dissertations

Water quality data and land use information were analyzed within the Alafia River watershed in Florida to determine spatial and temporal trends in these variables over a 16 year time period from 1991-2006. Monthly water quality data (for dissolved oxygen, turbidity, fecal coliform, total phosphorus, and total nitrogen) were statistically analyzed using the modified seasonal Kendall nonparametric test for trends that accounts for serial correlation. The statistical trend analysis was conducted for the entire study period, but monthly, seasonal, and land use trends were also examined. Land use information was examined using Geographic Information Systems to determine the percent change …
