Mapping And Assessing Urban Impervious Areas Using Multiple Endmember Spectral Mixture Analysis: A Case Study In The City Of Tampa, Florida, Fenqing Weng

USF Tampa Graduate Theses and Dissertations

The advance in remote sensing technology helps people more easily assess urban growth. In this study, the utility of multiple endmember spectral mixture analysis (MESMA) is examined in a sub-pixel analysis of Landsat Thematic Mapper (TM) imagery to map urban physical components in Tampa, FL. The three physical components of urban land cover (LC): impervious surface, vegetation and soil, were compared using the proposed MESMA with a traditional spectral mixture analysis (SMA). MESMA decomposes each pixel to address the heterogeneity of urban LC characteristic by allowing the number and types of endmembers to vary on a per pixel basis. This …

Selling The Third Wave: The Commodification And Consumption Of The Flat Track Roller Girl, Mary Catherine Whitlock

USF Tampa Graduate Theses and Dissertations

In an ethnographic examination of the "modern" roller derby movement that began in the early 2000s, I explore Women's Flat Track Derby in Florida. What does it mean to be a roller derby player? How is she conceptualized and commodified? Or more centrally, how is third wave feminism used as a catalyst of this commodification? In order to fully appreciate, understand, and even embrace roller derby, I look at roller derby leagues as social movement organizations (SMOs) in order to note how they frame themselves and maintain collective identity the commodification of third wave feminism. First, I will explore various …

Evaluation Of Repeated Biomarkers: Non-Parametric Comparison Of Areas Under The Receiver Operating Curve Between Correlated Groups Using An Optimal Weighting Scheme, Ping Xu

USF Tampa Graduate Theses and Dissertations

Receiver Operating Characteristic (ROC) curves are often used to evaluate the prognostic performance of a continuous biomarker. In a previous research, a non-parametric ROC approach was introduced to compare two biomarkers with repeated measurements. An asymptotically normal statistic, which contains the subject-specific weights, was developed to estimate the areas under the ROC curve of biomarkers. Although two weighting schemes were suggested to be optimal when the within subject correlation is 1 or 0 by the previous study, the universal optimal weight was not determined. We modify this asymptotical statistic to compare AUCs between two correlated groups and propose a solution …

Resisting Criminalization Through Moses House: An Engaged Ethnography, Lance Arney

USF Tampa Graduate Theses and Dissertations

Neoliberal restructuring of the state has had destructive effects on families and children living in urban poverty, compelling them to adapt to the loss of social welfare and demolition of the public sphere by submitting to new forms of surveillance and disciplining of their individual behavior. A carceral-welfare state apparatus now confines and controls the bodies of expendable laborers in urban spaces, containing their threat to the neoliberal socioeconomic order through criminalization and workfare assistance, resulting in a new symbiosis of prison and ghetto. The resulting structures of punishment, police surveillance, and criminalization primarily surround African Americans living in high …

Becoming The Corporate Native...Virtually: An Ethnography And Corporate Culture Assessment Of A Virtual Organization, Jennifer Laurel Avery

USF Tampa Graduate Theses and Dissertations

This dissertation presents an investigation of a rarely studied business entity in the cross disciplinary literature on organizational culture, a completely virtually organized firm. Subscribing to a conviction that any culture can only be understood through an approach that uncovers the lived experiences of its members, I employ the traditional anthropological method of participant observation as my foundational data gathering technique. In an effort to help engage anthropology with the cross disciplinary organizational culture literature generally, I also use two well-known methods of corporate culture assessment from the management sciences. I provide a number of recommendations to the sponsors of …

Paleo-Indian To Spanish Occupation Around Choctawhatchee Bay, Northwest Florida, As Documented In A Private Artifact Collection, Deena Woodward

USF Tampa Graduate Theses and Dissertations

This project documents and analyzes a substantial private collection of artifacts from archaeological sites around Choctawhatchee Bay, northwest Florida. The goals are to determine what the materials can contribute to the archaeological record, how they enhance our knowledge of the people who lived there over the past 2000 years, and how this information can be used to expand or contradict models of prehistoric lifeways in this region. This is done by comparing artifact assemblages, looking at site distribution patterns, and using pXRF trace-element analysis to compare Late Archaic clay objects with those from elsewhere along the Gulf.

An Exploratory Study Of Reception Of Organizational Citizenship Behaviors And Work Related Outcomes: It Is Good For Your Co-Workers, Xinxuan Che

USF Tampa Graduate Theses and Dissertations

The predictors of organizational citizenship behavior (OCB) - performance that supports the social and psychological environment in which task performance takes place - have been studied extensively in previous research. Surprisingly, only a few studies have looked into OCB's effects on individuals who might benefit from it. The purpose of the current study was to explore effects of individual-level OCB on its recipients. Reception of OCB (ROCB) is described and proposed to be related to targets' performance, job stress and job strains. In addition, narcissism and proactive personality were explored as predictors of reception of OCB also as moderators of …

Digital Holographic Measurement Of Nanometric Optical Excitation On Soft Matter By Optical Pressure And Photothermal Interactions, David C. Clark

USF Tampa Graduate Theses and Dissertations

In this dissertation we use digital holographic quantitative phase microscopy to observe and measure phase-only structures due to induced photothermal interactions and nanoscopic structures produced by photomechanical interactions. Our use of the angular spectrum method combined with off-axis digital holography allows for the successful hologram acquisition and processing necessary to view these phenomena with nanometric and, in many cases, subnanometric precision. We show through applications that this has significance in metrology of bulk fluid and interfacial properties.

Our accurate quantitative phase mapping of the optically induced thermal lens in media leads to improved measurement of the absorption coefficient over existing …

Can You Believe She Did That?!:Breaking The Codes Of "Good" Mothering In 1970s Horror Films, Jessica Michelle Collard

USF Tampa Graduate Theses and Dissertations

The threats found in horror films change with time, each decade consisting of threats that were most frightening for the time period. Horror film scholars, such as Andrew Tudor, determined that in 1970s horror films the threat has migrated from external forces into the home and the family. Invading aliens and monsters were thrown replaced by psychosis and evil children. This notion of making the familiar unfamiliar and threatening is paralleled in concerns addressed during the second-wave of feminism; women were making the normative and familiar idea of mother unfamiliar as they migrated from the private and into the public …

Talking About Talk: The Problem Of Communication As An Object Of Study In Public Participation Research, Lauren Leigh Cutlip

USF Tampa Graduate Theses and Dissertations

When citizens participate in risk assessment and decision-making for environmental and other issues that affect members of the public, more robust decisions may be made. Public participation in policy decisions is not only more democratic, but it also enables members of the public to contribute valuable expertise to the decision-making process. However, the development of an effective forum for such participatory projects has been difficult. Participation mechanisms that foster dialogue and interactive exchange between participants have been regarded as the most beneficial, but the practical application of these mechanisms has been observed to be problematic. The goal of this study …

Variability In Hydrology And Ecosystem Properties And Their Role In Regulating Soil Organic Matter Stability In Wetlands Of West-Central Florida, Sharon Jean Feit

USF Tampa Graduate Theses and Dissertations

Soil organic matter (SOM) provides many ecosystem services that are necessary for continued ecosystem function. The accumulation of SOM in an ecosystem is a function of its persistence time which can range from days to thousands of years. Ecosystem properties including dominant vegetation type, soil texture, and soil moisture in various habitats can regulate the persistence time of SOM.

Wetlands, because of their associated ecosystem properties, promote SOM accumulation, but little has been done to determine the ecosystem properties that regulate its persistence over time. In west-central Florida, urbanization and increased water demands have suppressed water tables in isolated wetland …

Tagline: Information Extraction For Semi-Structured Text Elements In Medical Progress Notes, Dezon K. Finch

USF Tampa Graduate Theses and Dissertations

Text analysis has become an important research activity in the Department of Veterans Affairs (VA). Statistical text mining and natural language processing have been shown to be very effective for extracting useful information from medical documents. However, neither of these techniques is effective at extracting the information stored in semi-structure text elements. A prototype system (TagLine) was developed as a method for extracting information from the semi-structured portions of text using machine learning. Features for the learning machine were suggested by prior work, as well as by examining the text, and selecting those attributes that help distinguish the various classes …

"People...Do Not Come With Standardized Circumstances": Toward A Model For An Anthropology Of E-Government, Marc K. Hebert

USF Tampa Graduate Theses and Dissertations

Many Americans appreciate the availability and ease of using government websites to conduct their business with the state. What then of the most vulnerable in society? How do they access and use a standardized application process for government assistance, considering their potential resource, educational and physical constraints? Many go to public libraries and non-governmental organizations (NGOs), which shifts the responsibility to help applicants from the government agency administering the program to local actors whose primary duties lie elsewhere.

The aim of this research is to document the experiences of three groups of people, primarily located in a central Florida, urban …

Comparative Outcomes Assessment Of The C-Leg And X2 Knee Prosthesis, Michael Jason Highsmith

USF Tampa Graduate Theses and Dissertations

Background

There are more than 300,000 persons in the U.S. living with transfemoral amputation (TFA). Persons with TFA use a knee prosthesis for gait and mobility. Presently, the C-Leg microprocessor knee prosthesis is the standard of care. C-Leg has significantly improved safety and cost efficacy and has created modest gains in gait efficiency. Recently, a new prosthesis has introduced a new sensor array and processor that reportedly improves knee motion, stair function and standing stability. Early claims of the reported functional benefits of the new Genium knee (formerly X2) have not been validated in a rigorous clinical trial. Therefore, the …

Parents' active involvement in their children's learning is a recommended strategy in engaging families in children's education experiences (Henderson & Mapp, 2002). The purpose of the current study was to measure the impact of parents' active participation in a parent-directed early literacy intervention on parental home-based involvement, school-based involvement, and home-school conferencing among Head Start parents and their preschool-aged children. The study used a …

Community As Metaphor: Dialectical Tensions Of A Racially Diverse Organization, Joseph Jacob Jenkins

USF Tampa Graduate Theses and Dissertations

In recent years, a sense of community has declined throughout the United States. Common Point Community Church has responded to this trend by prioritizing "community" as an organizational metaphor. The present study explores how this metaphor is co-constructed through the communication practices of current organizational leaders and members. I begin this process, first, by positioning the study within existing literature on institutional theory, institutional legitimacy, community, community of practice, social construction of race, sensemaking, organizational metaphor, tension-centered approach, and dialectic theory. Building upon more than three years of ethnographic field work, I then outline the study's context and methodology. Next, …

Semantic Feature Distinctiveness And Frequency, Katherine Marie Lamb

USF Tampa Graduate Theses and Dissertations

Lexical access is the process in which basic components of meaning in language, the lexical entries (words) are activated. This activation is based on the organization and representational structure of the lexical entries. Semantic features of words, which are the prominent semantic characteristics of a word concept, provide important information because they mediate semantic access to words. An experiment was conducted to examine the importance of semantic feature distinctiveness and feature frequency in accessing the lexical representations of young and older adults in an off-line task using features of animals. The McRae, Cree, Seidenberg, and McNorgan (2005) feature norm corpus …

Precipitation Of Phosphate Minerals From Effluent Of Anaerobically Digested Swine Manure, Alex Y. Lin

USF Tampa Graduate Theses and Dissertations

Swine production represents approximately 40% of the world's meat production, and its wastes contain high concentrations of organic carbon, nitrogen (N), and phosphorus (P). Anaerobic digestion is an increasingly popular technology for treating animal wastes while simultaneously generating energy. Its propagation and ability to solubilize organic N and P make adding a struvite recovery process attractive. Recovering struvite (MgNH4PO4) from anaerobically digested swine waste can address global P shortages, meet P discharge guidelines, and produce slow-release fertilizer, which can be sold for revenue.

Anaerobic digesters were operated with at organic loading rates of 3.4-3.9 g volatile solids per liter per …

Graphene Casimir Interactions And Some Possible Applications, Anh Duc Phan

USF Tampa Graduate Theses and Dissertations

Scientific development requires profound understandings of micromechanical and nanomechanical systems (MEMS/NEMS) due to their applications not only in the technological world, but also for scientific understanding. At the micro- or nano-scale, when two objects are brought close together, the existence of stiction or adhesion is inevitable and plays an important role in the behavior operation of these systems. Such effects are due to surface dispersion forces, such as the van der Waals or Casimir interactions. The scientific understanding of these forces is particularly important for low-dimensional materials. In addition, the discovery of materials, such as graphitic systems has provided opportunities …

Walking In The Land Of Cars: Automobile-Pedestrian Accidents In Hillsborough County, Florida, Marc Aaron Poling

USF Tampa Graduate Theses and Dissertations

Analyses of traffic accidents are often focused on the characteristics of the accident event and hence do not take into account the broader neighborhood contexts in which accidents are located. This thesis seeks to extend empirical analyses of accidents by understanding the link between accidents and their surroundings. The case study for this thesis is Hillsborough County, Florida, within which the city of Tampa is located. The Tampa Bay region ranks very high in terms of accident rates within U.S. metropolitan areas and is also characterized by transport policies which favor private automobiles over mass transit options, making it an …
