The Ecology And Morphology Of Deep-Sea Benthic Foraminifera: The Australian Margin And Epifaunal Pore Characteristics, Jake Willingham

All-Inclusive List of Electronic Theses and Dissertations

The distribution and abundance patterns of modern benthic foraminifera are used by paleoceanographers to assess changes in ocean conditions over geologic time. Examination of modern foraminiferal analogs provides the means to determine how these single-celled protists record clues about ambient conditions in their morphology and abundance/distribution patterns. Abundance and vertical distribution patterns of deep-sea benthic foraminifera were examined along the South Australian Margin and Tasman Sea of Australia. This was one of the first studies to examine microhabitat preferences of living (Rose Bengal stained) deep-sea benthic foraminifera within the region. A total of 11 sediment cores were collected via multicorer. …

Constitutional Exaptation, Political Dysfunction, And The Recess Appointments Clause, Jay D. Wexler

Faculty Scholarship

The so-called Recess Appointments Clause of the Constitution provides that: “The President shall have Power to fill up all Vacancies that may happen during the Recess of the Senate, by granting Commissions which shall expire at the End of their next Session.”1 As of only a few years ago, I considered this clause so minor and quirky that I included it in a book about ten of the Constitution’s “oddest” clauses, right alongside such clearly weird provisions as the Title of Nobility Clause and the Third Amendment.2 Though I recognized that the Recess Appointments Clause was probably the least odd …

Potential Targeted Therapeutic Strategies For Overcoming Resistance In Braf Wild Type Melanoma, Vito William Rebecca

USF Tampa Graduate Theses and Dissertations

Melanoma manifests itself from the malignant transformation of melanocytes and represents the deadliest form of skin cancer, being responsible for the disproportionate majority of all skin cancer deaths. The 2002 discovery that 50% of all melanoma patients possess activating BRAF mutations ignited a significant paradigm shift in the way the melanoma field approached research and how patients were treated [1]. The era of targeted therapy had begun and with it came successful targeted BRAF inhibitor therapy regimens, which have accomplished improved clinical benefit (response rate, progression free survival, and overall survival) compared with treatment with chemotherapy in three phase III …

Caribbean Traditions In Modern Choreographies: Articulation And Construction Of Black Diaspora Identity In L'Ag'ya By Katherine Dunham, Viktoria Tafferner-Gulyas

USF Tampa Graduate Theses and Dissertations

The interdisciplinary field of Dance Studies as a separate arena focusing on the social, political, cultural, and aesthetic aspects of human movement and dance emerged in the late 1980s and early 1990s. Dance criticism integrated Dance Studies into the academy as critics addressed the social and cultural significance of dance. In particular, Jane Desmond created an integrated approach engaging dance history and cultural studies; in the framework of her findings, dance is read as a primary social text. She emphasizes that movement style is an important mode of distinction between social groups, serving as a marker for the production of …

The Effect Of Ovulation As A Male Mating Prime On Drinking And Other Mating Behaviors, Robin Tan

USF Tampa Graduate Theses and Dissertations

A recent line of research grounded in evolutionary theory has shown that exposure to women's fertility cues affects men's mating cognition and behavior. This area of research has not yet been examined in relation to alcohol. As alcohol has also been shown to facilitate the formation of sexual connections for males, establishing the intersection between these two lines of research seems necessary to understand the impetus behind human behavior. Ninety-eight male participants were primed with either the scent of a fertile woman or the scent of nonfertile woman and then completed measures assessing their level of attraction to pictures of …

Physical And Mental Health Status Of Adults With Serious Mental Illness Participating In A Jail Diversion Intervention, Robin Telford

USF Tampa Graduate Theses and Dissertations

Adults with mental illnesses are at an increased risk to be diagnosed with one or more comorbid physical illnesses compared to the general population. Much of the disparities faced by adults with serious mental illnesses (SMI) can be attributed to medication side effects, increased risk for metabolic diseases, inability to communicate about severity and monitor physical health symptoms, poor health behaviors, high rates of smoking, and poor quality health care. The rate of physical illnesses for adults with mental illnesses are even higher among those who have been involved with the criminal justice system. In order to understand the relationship …

Craniometric Ancestry Proportions Among Groups Considered Hispanic: Genetic Biological Variation, Sex-Biased Asymmetry, And Forensic Applications, Meredith L. Tise

USF Tampa Graduate Theses and Dissertations

Today, groups considered Hispanic in the United States consist of populations whose complex genetic structures reflect intermixed diverse groups of people who came in contact during Spanish colonization in Latin America. After coming in contact and wiping out most of the Native Americans who occupied North and Latin America, the Spanish also introduced West African individuals for labor to begin developing crops to be shipped back to Europe, resulting in the Trans-Atlantic African slave trade. These migration events and differential gene flow among males and females that occurred throughout Latin America have led to populations that have been genetically transformed …

Developing An In-Season Predictor Of Commercial Landings For Quota Monitoring In The U.S. Virgin Islands, Mary Janine Vara

USF Tampa Graduate Theses and Dissertations

The lack of timely reporting of commercial fisheries landings interferes with effective management of fisheries in United States Virgin Islands (USVI). Federal law requires that landings be limited to prevent annual catch limits (ACLs) from being exceeded. Previous attempts to predict total landings have used historic data from prior fishing seasons to predict future landings rather than leveraging available in-season data to provide a more real-time prediction of landings. This study presents an in-season model that predicts total landings using partial reports from the current fishing year. This estimate of total landings, including error bounds around that estimate, can then …

Nanodiamond Based Composite Structures For Biosensing Applications, Pedro Javier Villalba

USF Tampa Graduate Theses and Dissertations

This dissertation presents the synthesis and application of nanodiamond based materials for electrochemical biosensors. In this research work, nanodiamond particles have been used to prepare doped and undoped nanocrystalline diamond films, and conducting polymer composites for enhanced biosensing. The performance of the synthetized materials towards sensing applications was evaluated against glucose amperometric biosensing. Besides, cholesterol biosensing was attempted to prove the capabilities of the platform as a generic biosensing substrate.

Biosensors have been proved to provide reliable detection and quantification of biological compounds. The detection of biological markers plays a key factor in the diagnosis of many diseases and, even …

Assessing The Impacts Of Unrestricted Pesticide Use In Small-Scale Agriculture On Water Quality And Associated Human Health And Ecological Implications In An Indigenous Village In Rural Panam[Aacute], Sarah Louise Watson

USF Tampa Graduate Theses and Dissertations

In 2014, the global pesticide industry's projected worth is $52 billion and by 2020, the developing world will make up one-third of the world's chemical production and consumption. Pesticides can have unintended negative consequences for human health and the environment, especially in the developing world where regulations are loose or nonexistent. One country with unrestricted use of pesticides is Panam[aacute], especially in Santa Rosa de Cucunatí. In this indigenous village, small-scale farmers and ranchers spray paraquat, glyphosate, picloram, and 2,4-D at higher elevations than the spring water source of a gravity-fed water system, the river, and the village. The objective …

A Synthesis Approach Of Trp-Like Primary Amine Peptoid Side Chains Used In Cyclic Beta-Hairpin - Like Scaffolds, Josanne-Dee Woodroffe

USF Tampa Graduate Theses and Dissertations

In recent studies it was reported that the D-amino acid containing peptide HYD1 was used in the treatment of necrotic cell death in multiple myeloma cell lines and showed promising biological activity and in vivo activity. It was meaningful to explore strategies for increasing the therapeutic efficacy of HYD1, a linear peptide. These efforts led to the development of MT1-101 (cyclized peptidomimetics), a lead compound that showed increased in vitro activity and in vivo activity. MTI-101 was found to bind the cell adhesion molecule CD44 and induce programmed necrosis in myeloma cell lines. It was important to improve on the …

Spatial And Temporal Extent Of A Subsurface Hydrocarbon Intrusion Following The Deepwater Horizon Blowout, Kathleen Watson

USF Tampa Graduate Theses and Dissertations

The Deepwater Horizon (DWH) oil spill in the Gulf of Mexico (GoM) released an estimated 4.9 million barrels of oil between April 20, 2010 and July 15, 2010. An estimated 36% of the oil formed a neutrally buoyant intrusion, containing both dissolved compounds and oil microdroplets, between 1000 and 1300 m depth. This study used geographic information systems software, and data from water samples that were collected as part of the National Resource Damage Assessment (NRDA), to determine that an area of at least 1,600 km² was exposed to DWH oil. Toxic BTEX (benzene, toluene, ethylbenzene, and …

Numerical Simulation Of Flow In Ozonation Process, Jie Zhang

USF Tampa Graduate Theses and Dissertations

In the last two decades, Computational Fluid Dynamics (CFD) has shown great potential as a powerful and cost-efficient tool to troubleshoot existing disinfection contactors and improve future designs for the water and wastewater treatment utilities.

In the first part of this dissertation two CFD simulation methodologies or strategies for computing turbulent flow are evaluated in terms of the predicted hydraulic performance of contactors. In the LES (large eddy simulation) methodology, the more energetic, larger scales of the turbulence are explicitly computed or resolved by the grid. In the less computationally intensive RANS (Reynolds-averaged Navier-Stokes) methodology, only the mean component of …

Structure-Based Design Of Novel Inhibitors And Ultra High Resolution Analysis Of Ctx-M Beta-Lactamase, Derek Allen Nichols

USF Tampa Graduate Theses and Dissertations

The emergence of CTX-M class-A extended-spectrum β-lactamases, which confer resistance to second and third-generation cephalosporins, poses a serious health threat to the public. CTX-M β-lactamases use a catalytic serine to hydrolyze the β-lactam ring. Specifically, the hydrolysis reaction catalyzed by CTX-M β-lactamase proceeds through a pre-covalent complex, a high-energy tetrahedral acylation intermediate, a low-energy acyl-enzyme complex, a high-energy tetrahedral deacylation intermediate after attack via a catalytic water, and lastly, the hydrolyzed β-lactam ring product which is released from the enzyme complex. The crystallographic structure of CTX-M at sub-angstrom resolution has enabled us to study enzyme catalysis as well as perform …

In response to the hitherto unchallenged assumptions supporting a globalized economy, the Leadership for Sustainability Education (LSE) program, formerly Leadership in Ecology, Culture, and Learning, was developed as part of an emerging sustainability movement. This article highlights the favorable conditions that provided the context for the evolution of the LSE program, including organizational policies and practices at Portland State University, and a commitment to community-university partnerships that conveyed the University’s motto, “Let Knowledge Serve the City.” We discuss the potential that higher education has to transform practices and ways of thinking necessary for ecological sustainability and social justice. Following this …

Searching For Biogeochemical Hot Spots In Three Dimensions: Soil C And N Cycling In Hydropedologic Settings In A Northern Hardwood Forest, Jennifer L. Morse, S F. Werner, Cody P. Gillin, Christine L. Goodale, Scott W. Bailey, Kevin J. Mcguire, Peter M. Groffman

Environmental Science and Management Faculty Publications and Presentations

Understanding and predicting the extent, location, and function of biogeochemical hot spots at the watershed scale is a frontier in environmental science. We applied a hydropedologic approach to identify (1) biogeochemical differences among morphologically distinct hydropedologic settings and (2) hot spots of microbial carbon (C) and nitrogen (N) cycling activity in a northern hardwood forest in Hubbard Brook Experimental Forest, New Hampshire, USA. We assessed variables related to C and N cycling in spodic hydropedologic settings (typical podzols, bimodal podzols, and Bh podzols) and groundwater seeps during August 2010. We found that soil horizons (Oi/Oe, Oa/A, and B) differed significantly …

The Role Of Culture In Social Development Over The Lifespan: An Interpersonal Relations Approach, Isabelle Albert, Gisela Trommsdorff

Online Readings in Psychology and Culture

This article aims to illustrate the role of culture for individual development throughout the life span. First, theoretical approaches how culture affects the ontogenesis is presented, starting from early anthropological to recent eco-cultural and culture-informed approaches. Then, culture-specific conceptualizations of development over the life span are discussed, focusing on development in childhood, adolescence, adulthood, and old age. Finally, we concentrate on selected areas of social development and report on recent studies on subjective theories, transmissions of values, and intergenerational relations. These studies are discussed as aspects of a more extended interpersonal relations approach to development within culture.

Altered Regional And Circuit Resting-State Activity Associated With Unilateral Hearing Loss, Xingchao Wang, Yang Fan, Fu Zhao, Zhenmin Wang, Jianqiao Ge, Kai Zhang, Zhixian Gao, Jia-Hong Gao, Yihong Yang, Jin Fan, Qihong Zou, Pinan Liu

Publications and Research

The deprivation of sensory input after hearing damage results in functional reorganization of the brain including cross-modal plasticity in the sensory cortex and changes in cognitive processing. However, it remains unclear whether partial deprivation from unilateral auditory loss (UHL) would similarly affect the neural circuitry of cognitive processes in addition to the functional organization of sensory cortex. Here, we used resting-state functional magnetic resonance imaging to investigate intrinsic activity in 34 participants with UHL from acoustic neuroma in comparison with 22 matched normal controls. In sensory regions, we found decreased regional homogeneity (ReHo) in the bilateral calcarine cortices in UHL. …

The Influence Of Gene Transfer Agents In Symbiodinium Associated Microbial Communities And The Coral Holobiont, Kelly O'Connell

USF St. Petersburg campus Honors Program Theses (Undergraduate)

Coral reefs serve an imperative role in the formation of marine ecosystems. They act as the foundation for complex food webs by supporting fish, sponges, algae, and invertebrates. However, coral bleaching and climate change have become major concerns in the conservation of ocean species over the past few decades. As a result, new methods of restoration are necessary for the propagation of these endangered coral species. This study focuses on the critical role that the symbiotic algae Symbiodinium, as well as their associated bacteria, play in the health of coral. A specific type of bacteria, α-proteobacteria, use virus-like particles called …

Delay Of Bud Break On 'Edelweiss' Grapevines With Multiple Applications Of Amigo Oil And Naa, Benjamin A. Loseke

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

‘Edelweiss’ is an important grape cultivar grown in the Midwestern part of the USA. This grapevine is tolerant to extreme winter temperatures which can be experienced in the areas where it is most widely grown. ‘Edelweiss’ is one of the earliest cultivars in the vineyard to break bud, making it very susceptible to late spring freezes. The primary buds of ‘Edelweiss’ produce a significant amount of fruit, while unlike many other hybrids, the secondary and tertiary buds will have little to no yields, thus making it important to protect the primary buds from a late freeze. The objective of this …

Non-Intrusive Anomaly Detection For Encrypted Networks, Luis C. Armendariz Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

The use of encryption is steadily increasing. Packet payloads that are encrypted are becoming increasingly difficult to analyze using IDSs. This investigation uses a new non-intrusive IDS approach to detect network intrusions using a K-Means clustering methodology. It was found that this approach was able to detect many intrusions for these datasets while maintaining the encrypted confidentiality of packet information. This work utilized the KDD '99 and NSL-KDD evaluation datasets for testing.

Parents' Value Of Play In Early Childhood: A Comparative Study Of Spousal Play Beliefs, Meghan C. Devito

Graduate Theses, Dissertations, and Problem Reports (ETD)

Play is a vital tool for developmental growth and learning in early childhood. However, with the current focus on academics, there is less emphasis placed on encouraging children to play. The current study investigated parental beliefs on play. The sample consisted of 34 middle-class couples (34 mothers, 34 fathers) co-parenting a preschool-aged child (3-5 years) attending the laboratory school of a large mid-Atlantic university. Participants were surveyed about their beliefs on play. Results revealed mothers' value of play to be higher than fathers'. Although significantly different, both mothers and fathers perceived play positively. The findings suggest that early childhood professionals …

The Germs Inside Me: Pediatric Patients' Conceptualization Of Illness And Regulation Of Emotions During Hospitalization, Sarah E. Buck

Graduate Theses, Dissertations, and Problem Reports (ETD)

The transition into a medical setting can be difficult for children under the age of 18. Previous research has identified a child's capacity to construct accurate representations of illness, in addition to the construction and application of adaptive strategies to modify emotional arousal, as significant predictors of successful adjustment to a medical environment. Preexisting research has neglected to investigate the constructs of illness conceptualization and regulatory systems of emotions. Using a sample of 26 pediatric patients and 26 adult informants, the current study explored the complex relationship between emotional regulation and the conceptualization of illness among children, from the ages …

Focusing specifically on a subset of the LGBT community – parents – this study documents the evolution of LGBT parents on American television. A total of 14 television shows were selected for a qualitative analysis. The parents depicted in these shows were analyzed according to gender, race, class and sexuality. The results were then summarized and put into historical context. This study contributes to the …

Choice And Control Of Enrichment For A Rescued And Rehabilitated Atlantic Bottlenose Dolphin (Tursiops Trunactus), Hannah Bahe

Honors Theses

Animals living under human care experience stress related to a lack of control over t environment. One way to remedy this is through the use of cognitive enrichment, su choice and control of enrichment. This type of enrichment has been shown to have benefits for animals under human care including increased activity and social interactions. To determine if choice and control was more beneficial than enrichmen alone, a three year old male Atlantic bottlenose dolphin (Tursiops truncatus) was ex to novel enrichment items in two experimental conditions. For the first condition, th animal was given a novel object. During the …

Impacts Of Non-Renewable Resource Extraction On Shrubland Songbird Nest Success And Abundance, Ryan Douglas Davis

Graduate Theses, Dissertations, and Problem Reports (ETD)

Shrubland songbirds are a highly imperiled guild across much of North America due to wide-scale land use changes and resulting loss of shrubland habitat. Land management practices which produce early-successional habitat, namely field abandonment and clearcut timber harvests, have become increasingly uncommon in the eastern United States, and natural maintenance processes such as fires and floods are often suppressed. The Appalachian region is rich in natural resources; it has historically seen high amounts of surface mining for coal and is currently experiencing prolific development of shale gas. Both of these practices alter local habitats and the landscape, and it is …

Immune Related Gene Expression Of Parasite-Resistant Sheep During A Haemonchus Contortus Infection, Karen Nicole Sommers

Graduate Theses, Dissertations, and Problem Reports (ETD)

Gastrointestinal nematode parasitism is a top health concern for sheep producers worldwide as traditional means of treatment are becoming less effective. Haemonchus contortus is of particular interest because it feeds on blood, causing significant pathological problems in the host. Certain breeds of sheep, like St. Croix, are more naturally resistant to parasitism. However, the underlying mechanisms that result in resistance are not fully understood. The following two experiments evaluated qPCR differential gene expression during the first ten days of a challenge H. contortus infection from lymph node and abomasal tissues. Experiment 1 evaluated 24 St. Croix hair lambs and 24 …
