A Mythography Of The Crossroads:How Is The Severance/Threshold/Return Progression In Both Mythology And Modern Wilderness Rites-Of-Passage Established Through Metaphor? An Enquiry Conducted Through Contemporary Storytelling Practice, Martin Shaw

Other Faculty of Arts, Humanities and Business Theses

How is the Severance/Threshold/Return progression in both mythology and modern wilderness rites-of-passage established through metaphor? An enquiry conducted through contemporary storytelling practice. This research examines the metaphorical structures within seven selected myths in relation to wilderness rites-of-passage, and the key thematic progression of Severance/Threshold/Return. These rites-of-passage are an essential component of an ongoing programme offered to the general public. The research is primarily creative in that the oral texts have been developed from extant myth over several years, and adapted to a variety of performance contexts. The evolution of these oral texts is examined in an analytical text, which draws …

Communicating The Unspeakable: Linguistic Phenomena In The Psychedelic Sphere, Diana R. Slattery

Other Faculty of Arts, Humanities and Business Theses

Psychedelics can enable a broad and paradoxical spectrum of linguistic phenomena from the unspeakability of mystical experience to the eloquence of the songs of the shaman or curandera. Interior dialogues with the Other, whether framed as the voice of the Logos, an alien download, or communion with ancestors and spirits, are relatively common. Sentient visual languages are encountered, their forms unrelated to the representation of speech in natural language writing systems. This thesis constructs a theoretical model of linguistic phenomena encountered in the psychedelic sphere for the field of altered states of consciousness research (ASCR). The model is developed from …

The Supervisory Assemblage: A Singular Doctoral Experience, Elizabeth Done

Other Faculty of Arts, Humanities and Business Theses

In this thesis, I apply Gilles Deleuze and Felix Guattari’s ontology of becoming to my own learning, thinking and writing. The adopted method - nomadic inquiry, is derived from the philosophising of Deleuze, whose concepts function as pedagogic values that I mobilise throughout my writing and perform – not merely explain, to problematise common perceptions of the thesis, supervision and doctoral experience. Deleuze resists models that inhibit context-specific creativity, yet I can readily identify the defining features of my own supervision: resolutely student-centred, facilitative of free experimentation, supportive of my becoming as an academic subject and the writing through which …

Sea Surface Temperature Variability In The Florida Keys And Its Relationship To Coral Cover, I. M. Soto, Frank E. Muller-Karger, Pamela Hallock, C. Hu

Marine Science Faculty Publications

The hypothesis that moderate variability in Sea Surface Temperature (SST) is associated with higher coral cover and slower rates of decline of coral cover within the Florida Keys National Marine Sanctuary (FKNMS) was examined. Synoptic SST time series covering the period 1994–2008 were constructed for the FKNMS with the National Oceanic and Atmospheric Administration Advanced Very High Resolution Radiometer satellite sensors. The SST data were compared with coral-cover time-series data from 36 sites monitored by the Coral Reef and Evaluation Monitoring Program. Sites that experienced moderately high SST variability relative to other sites showed a trend toward higher percentage coral …

New Phosphated Poly(Methyl Methacrylate) Polymers For The Prevention Of Denture-Induced Microbial Infection: An In Vitro Study, Antony Raj, Andrew R. Dentino

School of Dentistry Faculty Research and Publications

Purpose: Poly(methyl methacrylate) (PMMA) has been widely used as a denture-base acrylic resin due to its excellent physical and mechanical properties. However, the material is highly prone to microbial fouling that often leads to Candida-associated denture stomatitis. Incorporation of phosphate groups into PMMA could facilitate adsorption of salivary antimicrobials and inhibit microbial adherence on the polymer surface. An in vitro study evaluated PMMA polymers containing varying amounts of phosphate group for their efficacy to inhibit Candida albicans adhesion, adsorb salivary histatin 5, and exhibit candidacidal activity.

Methods: Six PMMA polymers containing 0%, 5%, 15%, 10%, 20%, and 25% of …

Rapid Evolution Of Fluoroquinolone-Resistant Escherichia Coli In Nigeria Is Temporally Associated With Fluoroquinolone Use, Adebayo Lamikanra, Jennifer L. Crowe, Rebeccah S. Lijek '07, Iruka N. Okeke

Biology Faculty Scholarship

The genetic basis for antimicrobial resistance was studied in fecal Escherichia coli isolates in a Nigerian community in parallel with antimicrobial use. The results showed that fluoroquinolones, and not chloroquine as has been hypothesized elsewhere, appear to be the selective force for fluoroquinolone-resistant fecal E. coli in this setting. Jennie Crowe and Rebeccah Lijek are student co-authors. --author-supplied description

2d Face Database Diversification Based On 3d Face Modeling, Qun Wang, Jiang Li, Vijayan K. Asari, Mohammad A. Karim, Manuel Filipe Costa (Ed.)

Electrical & Computer Engineering Faculty Publications

Pose and illumination are identified as major problems in 2D face recognition (FR). It has been theoretically proven that the more diversified instances in the training phase, the more accurate and adaptable the FR system appears to be. Based on this common awareness, researchers have developed a large number of photographic face databases to meet the demand for data training purposes. In this paper, we propose a novel scheme for 2D face database diversification based on 3D face modeling and computer graphics techniques, which supplies augmented variances of pose and illumination. Based on the existing samples from identical individuals of …

Design Of Small Scale Anaerobic Digesters For Application In Rural Developing Countries, Laurel Erika Rowse

USF Tampa Graduate Theses and Dissertations

The high incidence of upper respiratory diseases, contamination of waterways due to pathogens and nutrients from human and animal wastes, unsustainable deforestation, gender disparities in burden of disease due to unequal exposure to indoor air pollutants, and carbon black emissions from the burning of solid fuels are interrelated problems in many developing countries. Small scale anaerobic digestion provides a means of alleviating these problems by treating livestock waste onsite to produce biogas (methane and carbon dioxide) in rural areas in developing countries. Fuel can then be used for cooking, lighting, and heating. Methane fuel is an alternative to traditional three-stone …

Homing Geographies : Sexuality And Community Among Homeless Youth In Los Angeles, Heather Chelsey Wollin

Theses, Dissertations, and Projects

Scholarly literature on sexuality and homeless youth has focused almost exclusively on young people nested within a culture of risk on the streets. This study broadens the body of work on this population by exploring how homeless and runaway youth in Los Angeles make meaning of their sexualities. While these individuals are extremely vulnerable and fragile, they also display remarkable resilience. Researchers conducted two sets of in person, semi-structured interviews with six homeless youth at a homeless service agency in Los Angeles as part of an HIV peer intervention project. The interviews focused on sex education and messages about sexuality, …

What The Spiritual Caregiver Should Know While Dealing With Survivors Of Ethnic Violence, Nazila Isgandarova

Khazar Journal of Humanities and Social Sciences

Ethnic cleansing and genocide are different terms but both involve violence as a main tool, and many women and girls suffer from this kind of violence. The challenge for the spiritual caregiver is to define the major emotional turmoil of the patient and offer a helping hand. The main terminology involves the words „ethnic cleansing‟, „genocide‟ and „violence.‟ The case study is the Khojali genocide, which was recognized in the US Congress as the “biggest tragedy of the year” (Extensions of Remarks from Congressional Record E463). The paper discusses the role of spirituality and the major spiritual challenges of the …

The Uses Of Expertise: Science, Medicine And Body/Self-Fashioning, Amanda J. Counts

Master's Theses

This paper draws on empirical evidence collected from pro-anorexia websites and qualitative interviews with dieters to develop an analysis of the uses of medical and scientific expertise in processes of body- and self-fashioning. It builds on previous work by examining how `lay publics' refashion expertise in order to use it for new purposes, sometimes contradictory to the purposes of medicine itself. Four distinct groups are analyzed: Women diagnosed with anorexia; women diagnosed with EDNOS (Eating Disorder Not Otherwise Specified); dieters using traditional methods of caloric restricting; and dieters using a new method called Primal Dieting. Overall, respondents indicated an ambivalence …

Predictors Of Academic Achievement And Failure Among Low-Income Urban African American Adolescents: An Ecological Perspective, Israel Moses Gross

Master's Theses

Predictors of academic achievement among urban low-income African American adolescents have primarily been investigated by examining "main effects," or limited interactions with conventional statistical techniques. This paper adds to the literature by examining the factors that influence academic outcomes among this population within an ecological systems framework. This allowed for a comprehensive understanding of how numerous protective and risk factors, across ecological settings, interact to influence academic outcomes.

Optimal Data Analysis (ODA) was employed to create prediction models for mathematic and reading achievement. ODA allowed for the examination of a vast number of variables in one statistical model without increasing …

Projects Of Identity Creation In English Languate Textbooks Aimed At Adult Immigrants: 1900 And 2000, Steven Herbert Fehr

Master's Theses

The purpose of this study is to investigate the temporal parallels and differences between adult immigrant education and latent identity projects intertwined with the textbooks being used in the classrooms. By analyzing a sample of textbooks from both the turn of the 20th and 21st century I attempt to find both similarities and differences between these two time periods. These two periods are similar in that they are when the largest number of immigrants arrived in America, but in many ways (global context, technology, and political environment) they are also very different. How the American educational system responded to these …

Emplacing Ideologies Of Risk And The Use Of The Built Environment In Two Women's Residential Clubs In Turn Of The 20th Century Chicago, Robin Bartram

Master's Theses

Risk emplacement is a way we might better understand how power relations are built into people's everyday lives, and thus how they may be contested. Though previous research has documented that built form can regulate and express ideology, little attention has been paid to how buildings are employed and utilized to manage risk. In this paper, I argue that differences in ideas about risk and the built form of two residential women's clubs in Progressive Era Chicago can be explained by emplaced risk ideologies. Risk ideologies are sets of ideas about danger, and risk emplacement is a practice that links …

Global Influences And Resistance Within: Inclusive Practices And South Africa's Apartheid Government, Jean Marie Fagin

Master's Theses

South Africa's racially segregating apartheid government officially lasted for over forty years, from 1948 to 1994. Black South Africans were the victims of established oppression resulting in poverty, poor health care, and limited educational opportunities. Black South Africans with disabilities faced even greater exclusion from society due to their physical and cognitive challenges. Education for black students was neither compulsory nor free, and few black students with disabilities received services.

During the apartheid regime (1948-1994), disability issues were being address globally. The United Nations issued declarations, conventions, and a programme of action devoted to people with disabilities. In the early …

Protein Kinase C Δ Is Critical For Nucleotide Excision Repair Of Cyclobutane Pyrimidine Dimers, Christopher Michael Negro

Master's Theses

Nucleotide excision repair (NER) is the process by which cells identify and repair bulky, helix-distorting DNA lesions such as ultraviolet (UV) radiation-induced cyclobutane pyrimidine dimers (CPD) and 6-4 photoproducts (6-4PP). NER in human cells is a complex biochemical process requiring several complementation groups. Defects in complementation group genes result in rare, autosomal recessive cancer syndromes such as xeroderma pigmentosum (XP), cockayne syndrome (CS), and trichothiodystrophy, supporting the tumor suppressive effects of NER. Protein Kinase C delta (PKCδ) expression is lost in squamous cell carcinomas where it functions as a tumor suppressor gene. Additionally, in response to UV radiation, PKCδ is …

Contributory Factors Of Extraneous New Bone Growth On The Endocranial Surfaces Of Human Infant And Sub-Adult Skeletal Remains, Mark Andrew Zahareas

Master's Theses

This study investigates the factors that may contribute to endocranial bone changes in human sub-adult skeletal remains in an effort to differentiate bone changes, or lesions, caused by pathological processes and those caused by growth and development. The contributory factors investigated included the presence of endocranial bone lesions, the age-at-death of the individual, the precise location of the bone change, the dynamic nature of the locations, and the presence (or absence) of postcranial and/or ectocranial indicators of pathology within the individual. The sample population used for this research was comprised of 129 individuals from 15 different Native American groups over …

Cattail (Typha X Glauca) Invasion In Wetlands Of The Great Lakes Region: Are Impacts Time-Dependent?, Mark Edwin Mitchell

Master's Theses

Some species introduced into new regions have the potential to greatly impact native diversity and ecosystem functioning. The invasive hybrid cattail, Typha X glauca, has established in wetlands across the Great Lakes region decreasing native plant diversity and altering soil and microsite characteristics. We utilized 80 years of historical aerial photographs from the Illinois Beach State Park wetland complex to map the spread and determine the age of T. X glauca stands. Floristic, edaphic, and environmental data were collected from plots across an invasion-age gradient to determine the impacts of T. X glauca and time since invasion on environmental variables. …

Community Structure And Secondary Production Of Aquatic Macroinvertebrates In Coastal Wetland Ponds Of The West Copper River Delta, Alaska, Following Tectonic Uplift, Ryan Glen Van Duzor

Master's Theses

The Great Alaska Earthquake of 1964 (magnitude 9.2) greatly altered the coastal landscape in southcentral Alaska and had particularly dramatic effects on the Copper River Delta (CRD), an ecologically and economically important area within the Chugach National Forest. The earthquake caused tectonic uplift (up to 3.5m) of the CRD coastal tidal marsh and transformed it into a perched freshwater marsh. Copper River Delta ponds, which are crucial habitat to a myriad of migrating songbirds, shorebirds, and waterfowl, are of particular interest to wildlife managers in the CRD and along the Pacific coasts of North, Central and South America. This study …

The River Continuum Redux: Aquatic Insect Diets Reveal The Importance Of Autochthonous Resources In The Salmon River, Idaho, Kathryn Vallis

Master's Theses

Along a river network, changes in the physical characteristics of a stream - changes articulated by the River Continuum Concept (RCC) - have been predicted to influence stream food webs, particularly the resources supporting aquatic macroinvertebrates. Although diets of macroinvertebrates can track resource availability along the longitudinal gradient of streams, insect diets were not assessed in the original RCC study; rather, insects were grouped into functional feeding groups (FFGs). In addition, global climate change is increasing the frequency and spatial extent of wildfire and beetle outbreaks throughout the western United States and could affect riparian vegetation and the amount of …

Wee1 Is A Biological Target Of The Mir-17-92 Cluster In Leukemia, Sonia Susan Olikara

Master's Theses

MicroRNAs are noncoding RNAs that bind to the 3' untranslated region of their mRNA targets, which causes downregulation of target gene expression. Previous studies have shown that the miR-17-92 cluster, which encodes six miRNAs, is overexpressed in leukemias arising from chromosomal translocations of the Mixed Lineage Leukemia (MLL) gene. In the present study, prediction algorithms identified WEE1, a kinase that inhibits cell cycle progression, as a possible target of five of the six miRNAs. Through luciferase reporter assays, we found that miR-17, miR-20a, and miR-18a specifically target nucleotides 465 to 487 of the 3' UTR of WEE1, while miR-19a and …

Notch-1 Specifically Activates Erk1/2 In Multiple Breast Cancer Subtypes, Allison Schuyler Rogowski

Master's Theses

Notch-1 is a cell fate regulatory protein and a potent breast oncogene. Notch-1 and its ligand Jagged-1 are over-expressed in human breast cancers that are associated with poor overall survival (Reedijk, Odorcic et al. 2005). Deregulated Notch signaling may contribute to tumorigenesis by increasing proliferation, inhibiting differentiation, and preventing apoptosis (Miele, Golde et al. 2006). The mitogen-activated protein kinase (MAPK) pathway is a critical cell signaling pathway that has been implicated in the development and progression of cancer (Hanahan and Weinberg 2000). Four major MAPK pathways are involved in both cell growth and apoptosis. The regulation of these pathways is …

Role Of Type Ii Transmembrane Serine Proteases In Coronavirus Production, Gitanjali Cuckemane Subramanya

Master's Theses

Proteolytic cleavage of Coronavirus spike proteins at the appropriate time and location results in efficient virus entry activation. Type II transmembrane serine proteases (TTSPs), specifically, transmembrane protease serine 2 (TMPRSS2) when expressed on target cells, enhance SARS coronavirus entry by activating spike cleavage. This study investigated the effect of TTSPs expressed in Coronavirus producer cells. Murine Hepatitis Virus strain A59 (MHV A59) viruses produced in the absence of TMPRSS2 required target cell protease activity - either cell surface serine proteases or endosomal acidophilic proteases - for entry. MHV A59 viruses produced in the presence of TMPRSS2 were less infectious overall, …

Estimating Groundwater Discharge In The Oligohaline Ecotone Of The Everglades Using Temperature As A Tracer And Variable-Density Groundwater Models, Victora Spence

USF Tampa Graduate Theses and Dissertations

Recent research suggests that brackish, marine-derived groundwater up-wells in the oligohaline ecotone of the coastal Everglades, bringing with it phosphorus to an otherwise phosphorus-poor environment. The purpose of this study is to estimate the rates and timing of the groundwater discharge by using variable-density groundwater models constructed, calibrated, and validated with field measurements of hydraulic head and surface and subsurface temperature. Modeled groundwater discharge rates ranged from 5.4E-04 mm/day in August to -1.3E-03 mm/day in June for Shark Slough and 4.8E-01 mm/day in June to -1.4E-01 mm/day in January for Taylor Slough, where positive values imply groundwater discharge and negative …

Comparison Of The Microbial Diversity And Abundance Between The Freshwater Land-Locked Lakes Of Schirmacher Oasis And The Perennially Ice-Covered Lake Untersee In East Antarctica, Jonathan Huang, Richard B. Hoover, Ashit Swain, Chris Murdock, Asim K. Bej

Research, Publications & Creative Work

Extreme conditions such as low temperature, dryness, and constant UV-radiation in terrestrial Antarctica are limiting factors of the survival of microbial populations. The objective of this study was to investigate the microbial diversity and enumeration between the open water lakes of Schirmacher Oasis and the permanently ice-covered Lake Untersee. The lakes in Schirmacher Oasis possessed abundant and diverse group of microorganisms compared to the Lake Untersee. Furthermore, the microbial diversity between two lakes in Schirmacher Oasis (Lake L27C and L47) was compared by culture-based molecular approach. It was determined that L27Chad a richer microbial diversity representing 5 different phyla and …

Robotic Hand Evaluation Based On Task Specific Kinematic Requirements, Carlos Rafael Neninger

USF Tampa Graduate Theses and Dissertations

With the rise autonomous and robotic systems in field applications, the need for dexterous, highly adaptable end effectors has become a major research topic. Control mechanisms of robotics hands with a high number independent actuators is recognized as a complex, high dimensional problem, with exponentially complex algorithms. However, recent studies have shown that human hand motion possesses very high joint correlation which translates into a set of predefined postures, or synergies. The hand produces a motion using a complementing contribution of multiple joints, called synergies. The similarities place variables onto a common dimensional space, effectively reducing the number of independent …
