Compound-Specific Stable Isotopic Analysis Of Protein Amino Acids: Ecological Applications In Modern And Ancient Systems, Greg Ellis

USF Tampa Graduate Theses and Dissertations

Stable isotopic analysis of the major biochemically important elements is an increasingly utilized tool in the study of ecology. Patterns of isotopic fractionation in carbon and nitrogen are used to determine trophic linkages, nutrient pathways, and sources of primary production in numerous contexts. Traditional techniques rely on measurements made of bulk samples such as tissue, but emerging methods using individual chemical compounds provide a means of achieving deeper understanding in a variety of inquiries.

Amino acids, as the building blocks of proteins, are the dominant nitrogen-bearing biomolecules and are a major constituent of all life. Patterns of isotopic fractionation during …

Evaluation Of Urinary Pesticide Biomarkers Among A Sample Of The Population In The United States, Alex Lance Lebeau

USF Tampa Graduate Theses and Dissertations

Pesticide use in the United States continues to attract negative public attention. In recent years, this attention has focused on the effects that chronic, low-level pesticides may have, especially on children and various sub-populations. Over the past decade, studies have attempted to correlate negative health effects with detections of pesticide biomarkers in biological media. The current research investigates biomarker of exposure levels in a sample of the United States population. Data from the 2001-2002 NHANES dataset (n=11,039) was evaluated. The detection frequency of urinary biomarkers of exposure and the geometric mean from the NHANES pesticide dataset (n=3,152) were determined. Of …

Water Quality Monitoring In A Pilot Marine Integrated Aquaculture System, Alex W. Kruglick

USF Tampa Graduate Theses and Dissertations

Land based aquaculture systems are growing in popularity, and there is a drive to improve the efficiency of their energy and water systems for both economic and environmental benefit. Recirculating Aquaculture Systems (RAS) generally refer to systems that recycle their wastewater streams to be more or less a zero discharge facility. A more sustainable approach is emerging in the form of Integrated Aquaculture Systems (IAS) where maximum utility is realized from the various components so that fresh water use is reduced, water quality is improved, energy use is reduced, and new markets are created or fulfilled. Under a grant from …

Incorporating Quantitative Reasoning In Common Core Courses: Mathematics For The Ghost Map, John R. Jungck

Numeracy

How can mathematics be integrated into multi-section interdisciplinary courses to enhance thematic understandings and shared common readings? As an example, four forms of quantitative reasoning are used to understand and critique one such common reading: Steven Berlin Johnson’s "The Ghost Map: The Story of London's Most Terrifying Epidemic - and How it Changed Science, Cities and the Modern World" (Riverhead Books, 2006). Geometry, statistics, modeling, and networks are featured in this essay as the means of depicting, understanding, elaborating, and critiquing the public health issues raised in Johnson’s book. Specific pedagogical examples and resources are included to illustrate applications and …

Using Gis To Enhance Programs Serving Emancipated Youth Leaving Foster Care, Catherine Batsche, Steven Reader

Dean's Office Publications

This article describes a GIS prototype designed to assist with the identification and evaluation of housing that is affordable, safe, and effective in supporting the educational goals and parental status of youth transitioning from foster care following emancipation. Spatial analysis was used to identify rental properties based on three inclusion criteria (affordability, proximity to public transportation, and proximity to grocery stores), three exclusion criteria (areas of high crime, prostitution, and sexual predator residence), and three suitability criteria (proximity to health care, mental health care, and youth serving organizations). The results were applied to four different scenarios to test the utility …

Overfishing Of The Common Snook, Allison Ashcroft

Undergraduate Journal of Mathematical Modeling: One + Two

The chief aim of this project is to determine if the populations of the common snook, Centropomus Undecimalis, in the Atlantic and Gulf coast are being affected by overfishing. This is established by evaluating the intrinsic rate of change for these populations and their carrying capacities. It turns out that the carrying capacity for the population of the Atlantic coast is approximately one million snook and its intrinsic rate is 0.00621, while the carrying capacity of the Gulf coast's population is 2.9 million snook and its intrinsic rate is 0.00165. The decline of both populations is most likely due …

Traditional Native American Foods: Stories From Northern Plains Elders, Sarah E. Colby, Leander R. Mcdonald, Greg Adkison

Journal of Ecological Anthropology

An understanding of traditional Native American food patterns is needed to develop efforts for decreasing chronic disease that include traditional Native American foods in culturally relevant ways. Via oral history-focused in-depth interviews, I explored traditional food and dietary practices among Native American Elders in the Northern Plains. In addition to staple foods discussed, five primary themes included hunger, sharing, gathering, medicine, and religion. Barriers to use of Native foods primarily concerned knowledge, convenience and availability.

Free Cysteine Modulates The Conformation Of Human C/Ebp Homologous Protein, Vinay K. Singh, Mona M. Rahman, Kim Munro, Vladimir N. Uversky, Steven P. Smith, Zongchao Jia

Molecular Medicine Faculty Publications

The C/EBP Homologous Protein (CHOP) is a nuclear protein that is integral to the unfolded protein response culminating from endoplasmic reticulum stress. Previously, CHOP was shown to comprise extensive disordered regions and to self-associate in solution. In the current study, the intrinsically disordered nature of this protein was characterized further by comprehensive in silico analyses. Using circular dichroism, differential scanning calorimetry and nuclear magnetic resonance, we investigated the global conformation and secondary structure of CHOP and demonstrated, for the first time, that conformational changes in this protein can be induced by the free amino acid l-cysteine. Addition of l-cysteine caused …

Zelinski, Sherry L. Willis, K. Warner Schaie, Boo Johannson, Marcus Praetorius, Roger A. Dixon, Dan M. Mungas, Scott M. Hofer, Andrea M. Piccinin

Psychology Faculty Publications

The present study used a coordinated analyses approach to examine the association of physical activity and cognitive change in four longitudinal studies. A series of multilevel growth models with physical activity included both as a fixed (between-person) and time-varying (within-person) predictor of four domains of cognitive function (reasoning, memory, fluency, and semantic knowledge) was used. Baseline physical activity predicted fluency, reasoning and memory in two studies. However, there was a consistent pattern of positive relationships between time-specific changes in physical activity and time-specific changes in cognition, controlling for expected linear trajectories over time, across all four studies. This pattern was …

Psychology Faculty Publications

Social activity is typically viewed as part of an engaged lifestyle that may help mitigate the deleterious effects of advanced age on cognitive function. As such, social activity has been examined in relation to cognitive abilities later in life. However, longitudinal evidence for this hypothesis thus far remains inconclusive. The current study sought to clarify the relationship between social activity and cognitive function over time using a coordinated data analysis approach across four longitudinal studies. A series of multilevel growth models with social activity included as a covariate is presented. Four domains of cognitive function were assessed: reasoning, memory, fluency, …

Environmental and Occupational Health Faculty Publications

PAHs were measured in water, sediment, and shrimps of Estero de Urias, an estuary in Sinaloa, Mexico, during the rainy and dry seasons, and analyzed for eleven PAHs routinely detected in samples. Phenanthrene was the most dominant congener in the water, sediment, and shrimp samples comprising about 38, 24, and 25%, respectively, of the eleven PAHs detected, followed by pyrene and naphthalene in water and sediment samples, and pyrene and fluorine in the shrimp samples. Total PAH concentrations ranged from 9 to 347 ng/L in water, 27 to 418 ng/g in sediments, and 36 to 498 ng/g in shrimps. The …

Energetic Plasticity Underlies A Variable Response To Ocean Acidification In The Pteropod, Limacina Helicina Antarctica, Brad A. Seibel, Amy E. Maas, Heidi M. Dierssen

Marine Science Faculty Publications

Ocean acidification, caused by elevated seawater carbon dioxide levels, may have a deleterious impact on energetic processes in animals. Here we show that high PCO₂ can suppress metabolism, measured as oxygen consumption, in the pteropod, L. helicina forma antarctica, by ∼20%. The rates measured at 180–380 µatm (MO₂  = 1.25 M^−0.25, p = 0.007) were significantly higher (ANCOVA, p  =  0.004) than those measured at elevated target CO₂ levels in 2007 (789–1000 µatm,  =  0.78 M^−0.32, p  =  0.0008; Fig. 1). However, we further demonstrate metabolic plasticity in response to regional …

Exploring The Advance Care Planning Experiences Among Persons With Mild Cognitive Impairment: Individual And Spousal Perspectives, Catherine Parsons Emmett

USF Tampa Graduate Theses and Dissertations

Advance Care Planning has been advocated for over 20 years as a way in which individuals who are no longer able to speak for themselves, may still convey their preferences regarding a wide of array of decisions, including medical care. Advance care planning may not be initiated by individuals for many reasons, and even when initiated, may not be specific enough to help guide decision making. Recent advance care planning models have utilized disease specific information to help guide end of life health care decision-making. Persons diagnosed with mild cognitive impairment face an increased possibility of developing dementia at some …

USF Tampa Graduate Theses and Dissertations

There is an urgent need for the development of an effective therapeutic vaccine against cancer caused by human papilloma virus (HPV). We focused on HPV-induced malignancies because of their high worldwide prevalence (e.g., cervical carcinoma and head & neck cancer). A successful therapeutic vaccine could prevent the 250 000 deaths/year worldwide and the 2.25 billion dollars that

are expended in related care in the US.

We used an HPV-induced mouse cancer model to test vaccines

composed of a CD8 T cell peptide epitope administered with potent adjuvants designed to generate vast numbers of high avidity cytotoxic T lymphocytes specific for …

Good Men Grow Corn: Embodied Ecological Heritage And Health In A Belizean Mopan Community, Kristina Linda Baines

USF Tampa Graduate Theses and Dissertations

Recent developments in land rights and land use in the Toledo district, Belize has generated anthropological and activist interest surrounding traditional ecological knowledge and practice, and the role of heritage in communities. This study explores the connection between ecological knowledge and practices, and the concurrent construction of heritage, and community health and wellness, broadly defined. Developing and using the concept of "embodied ecological heritage," this dissertation takes a phenomenological approach to understanding the convergence of ecological heritage and health in multiple realms of everyday life, arguing that lived experience of participating in "traditional" practices is fundamentally connected to wellness in …

Stable Carbon Isotope Discrimination By Rubisco Enzymes Relevant To The Global Carbon Cycle, Amanda J. Boller

USF Tampa Graduate Theses and Dissertations

Five different forms of ribulose 1,5-bisphosphate carboxylase/oxygenase (RubisCO; IA, IB, IC, ID, II), the carboxylase of the Calvin-Benson-Bassham cycle (CBB), are utilized by plants, algae and autotrophic bacteria for carbon fixation. Discrimination against ¹³C by RubisCO is a major factor dictating the stable carbon isotopic composition (δ¹³C = {[¹³C/¹²C sample/¹³C/¹²C standard] - 1} X 1000) of biomass. To date, isotope discrimination, expressed as ε values (={[¹²k/¹³k] - 1} X 1000; ¹²k and ¹³k …
