Development Of Models For Understanding Causal Relationships Among Activity And Travel Variables, Xin Ye

USF Tampa Graduate Theses and Dissertations

Understanding joint and causal relationships among multiple endogenous variables has been of much interest to researchers in the field of activity and travel behavior modeling. Structural equation models have been widely developed for modeling and analyzing the causal relationships among travel time, activity duration, car ownership, trip frequency and activity frequency. In the model, travel time and activity duration are treated as continuous variables, while car ownership, trip frequency and activity frequency as ordered discrete variables. However, many endogenous variables of interest in travel behavior are not continuous or ordered discrete but unordered discrete in nature, such as mode choice, …

Before The Inca: Prehistoric Dietary Transitions In The Argentine Cuyo, Nicole Shelnut

USF Tampa Graduate Theses and Dissertations

A dietary reconstruction was performed in order to understand changing prehistoric subsistence patterns in the Central Andean geographical area of the Argentine Cuyo that includes the provinces of San Juan and Mendoza. Archaeologically, the Cuyo is also known as a boundary between Andean agriculturalists and the foragers of Patagonia. One hypothesis being tested is whether this area was one of the last South American cultural groups to convert to maize cultivation, probably around 2000 BP. The process of stable isotope analysis is used to reconstruct the diets of individuals, as it reveals the relative proportions of C3 and C4 plants …

Modeling The 100-Year Flood Using Gis: A Flood Analysis In The Avon Park Watershed, Alan Stephen Booker

USF Tampa Graduate Theses and Dissertations

Using hydraulic modeling and Geographic Information System (GIS) software, the 100-year flood was delineated for the municipality of Avon Park located in Highlands County, Florida. A detailed and rigorous approach was undertaken to first collect and develop an extensive spatial database to store the data collected that is pertinent to the model. This analysis combined ArcGIS version 8.3 and the Interconnected Channel and Pond Routing (ICPR) model version 3.02 to develop hydraulic models that assigned regulatory flood elevation within the watershed. The model results were post processed and brought into GIS to delineate the 100-year flood.The steps outlined in this …

“Fit For The Reception Of Ladies And Gentlemen”: Power, Space, And Politeness In Eighteenth-Century Anglo-Atlantic Playhouses, Troy Thompson

USF Tampa Graduate Theses and Dissertations

Eighteenth-century English men and women ventured to the playhouse for a night of festive revelry and entertainment. Despite the raucousness (compared to our vision of a night at the theatre), theatergoing was a polite endeavor and as such equipped with the material pleasantries of bourgeois society. But unlike other spaces reserved for the middle and upper classes, all manner of people could and did attend the theatre. Thus, particular methods of physically and visually separating social classes arose within the eighteenth-century playhouse.

In this thesis, I investigate these material phenomena, particularly the ways in which theatre managers, players, as well …

The Application Of A Modified Human Development Index: Spatial Modeling Of Socioeconomic Well-Being For Florida Counties, Clay Kelsey

USF Tampa Graduate Theses and Dissertations

This thesis uses the United Nations Human Development Index as a model for comparing a selected set of socioeconomic indicators across Florida’s sixty-seven counties. Whether for urban planning, hazards mitigation, transportation forecasting, or other county-level and state-level functions, information and understanding of socioeconomic conditions are keys to efficient planning and policy making, both in the early development stages as well as during implementation. A summary overview of socioeconomic well-being and its distribution across a given area offers a distinct advantage in terms of deciding where planning or policy changes are most needed and where they will prove most beneficial.

The Mucilage Of Opuntia Ficus Indica: A Natural, Sustainable, And Viable Water Treatment Technology For Use In Rural Mexico For Reducing Turbidity And Arsenic Contamination In Drinking Water, Kevin Andrew Young

USF Tampa Graduate Theses and Dissertations

The use of natural environmentally benign agents in the treatment of drinking water is rapidly gaining interest due to their inherently renewable character and low toxicity. We show that the common Mexican cactus produces a gum-like substance, cactus mucilage, which shows excellent flocculating abilities and is an economically viable alternative for low-income communities. Cactus mucilage is a neutral mixture of approximately 55 high-molecular weight sugar residues composed basically of arabinose, galactose, rhamnose, xylose, and galacturonic acid. We show how this natural product was characterized for its use as a flocculating agent. Our results show the mucilage efficiency for reducing arsenic …

The Effect Of Dem Resolution On The Computation Of Hydrologically Significant Topographic Attributes, David Alexander Crosby

USF Tampa Graduate Theses and Dissertations

Terrain attributes computed from Digital Elevation Models (DEMs) are widely used in hydrology and hydrologic modeling. It is important to consider that the values of the attributes can be different depending on the resolution of the DEM from which they are derived. The question arises as to how much exactly the high-resolution DEMs created through LIDAR remote sensing techniques change the values of the terrain attributes when compared to lower resolution DEMs.In this thesis a LIDAR-derived DEM of 20 feet resolution was resampled using a nearest-neighbour algorithm to various coarser resolutions to examine and quantify the effect of DEM resolution …

Rethinking The Monumental: The Museum As Feminist Space In The Sexual Politics Exhibition, 1996, Devon P. Larsen

USF Tampa Graduate Theses and Dissertations

Rethinking the monumental suggests not only a reconsideration of Judy Chicago’s controversial installation The Dinner Party (1979)--as displayed in the group feminist art exhibition, Sexual Politics: Judy Chicago’s Dinner Party in Feminist Art History--but also refers to an unfixing of the monumental position of power afforded the museum and a re-invigoration of the debate in feminist visual art regarding the use of the female body. I use the Sexual Politics exhibition, curated by Amelia Jones for the University of California at Los Angeles Armand Hammer Museum and Cultural Center (1996) as an indicator of the museum as feminist space. Sexual …

The Influence Of Roads On The Florida Panther, Autumn C. Schwab

USF Tampa Graduate Theses and Dissertations

The Florida panther (Puma concolor coryi) is a relatively well studied species, but some aspects of its habitat requirements remain poorly understood. While it has been well established that the most important threat to panthers include limited habitat area and continued habitat loss and fragmentation, the importance of roads in this context has not been determined. The goal of this research is to determine the influence of roads on the movement patterns of the Florida panther. Panther telemetry data from 1981 until 2003 was used, as well as detailed road networks and vegetation maps. The influence of roads on individual …

Displaced Self And Sense Of Belonging: A Chinese Researcher Studying Chinese Expatriates Working In The United States, Zhong (June) Wang

USF Tampa Graduate Theses and Dissertations

In this dissertation, I tell the story of the ethnographic fieldwork I conducted between 1997 and 2005 in which I focused on a group of expatriates sent by one of China's largest multinational corporations to work in the U.S. for extended years. My initial interest was to investigate how this Chinese state-owned multinational company operated its overseas subsidiaries in the U.S. However, as my fieldwork progressed, I became increasingly interested in how the expatriates' and their family members' careers and lives were impacted by globalization, how these Chinese expatriates and family members adjusted, adapted, understood, and tolerated cultural differences inside …

Key objectives were to: 1. identify factors that have a significant effect on mountain climbing frequency; 2. collect information from physical trail and route evaluation to develop an interim classification index; 3. combine relevant variables to formulate a composite Fourteeners Environmental Degradation Index (FEDI) and use it to evaluate, rank, and compare …

An Ahp Framework For Balancing Efficiency And Equity In The United States Liver Transplantation System, Vijayachandran M. Veerachandran

USF Tampa Graduate Theses and Dissertations

ABSRACT: Liver transplantation and allocation has been a controversial issue in the United States for decades. One of the main concerns in the allocation system is the trade-off between the two main objectives, efficiency and equity. Unfortunately, it is difficult to reach consensus on how to develop allocation policies that aim at balancing efficiency and equity, among transplantation policy makers, administrators, transplant surgeons and transplant candidates.Our research identifies and classifies the outcomes of liver allocation into two major categories, efficiency and equity, that are, often times, conflicting. Previous researchers did not consider how to balance outcomes in these two categories. …

Workers, Unions, And The Globalization Of Production: Structural And Institutional Challenges For Organized Labor In The United States, Matthew Kohen

USF Tampa Graduate Theses and Dissertations

In this thesis, I argue that the globalization of production has weakened the power and efficacy of labor unions in the United States. I describe the globalization of production as a set of transformations in both the institutional structure of the economy and in the organization of production, and discuss how these transformations have impacted workers and unions in the American economy. The theoretical framework I employ is the social structure of accumulation approach, which emphasizes the importance of the institutional structures of capitalist economies and how their interaction with forms of production organization and systems of labor control helps …

The Role Of Social Structural And Social Contextual Factors In Shaping Chronic Disease And Chronic Disease Risk Behavior: A Multilevel Study Of Hypertension, General Health Status, And Mental Distress, Caroline Mae Mckay

USF Tampa Graduate Theses and Dissertations

At present there is a reliance on behavioral interventions that have been limited in their effectiveness to reduce the public health burden of chronic disease, partly because the effects of social context on the initiation and maintenance of health behaviors is not incorporated into public health policy and practice. Yet current research indicates that there are macro-level structural and contextual influences on population health that cannot be reduced to individual or compositional effects. This study investigated the associations between social structural factors, community social context, individual characteristics, and self-reported correlates of disease. Distal influences included social structural inequalities such as …

Community Of Practice As Community Of Learners: How Foreign Language Teachers Understand Professional And Language Identities, Ruth Ban

USF Tampa Graduate Theses and Dissertations

This study seeks to understand the transmogrification of four Mexican foreign language teachers as they participate in a teaching exchange in American schools throughout the United States. Previous research into development of competent membership in given communities of practice points to the need for mutual engagement with other community members, an understanding of the community activity, and a shared repertoire among community members. Framed within an activity theory perspective, the present study examined how the teachers's socio-historical background, cultural tools and artifacts, along with other pedagogical activities, community rules, and division of labor mediated the teachers' understanding of their professional …

Implementing School-Wide Positive Behavior Support: Exploring The Influence Of Socio-Cultural, Academic, Behavioral, And Implementation Process Variables, Rachel Mara Cohen

USF Tampa Graduate Theses and Dissertations

This study evaluated the influence of academic, behavioral, and sociocultural variables on the implementation of Schoolwide Positive Behavior Support (SWPBS), a system intended to improve discipline in school buildings. The number of schools that are implementing SWPBS has been increasing dramatically over the years as school violence continues to rise and solutions are needed to improve school climate. This study examined the relationship between three categories of variables and the level of implementation of SWPBS in three multiple regression analyses. The categories were school demographic variables (i.e., ethnicity, socio-economic status, teacher: student ratio, percentage of teachers who are out-of-field), severity …

Gene Expression Profiles And Clinical Parameters For Survival Prediction In Stage Ii And Iii Colorectal Cancer Patients, Mubeena Begum

USF Tampa Graduate Theses and Dissertations

Prediction of outcome in colorectal cancer (CRC) is currently based on the TNM staging classification; however, histopathological classification alone is insufficient for accurately predicting survival in stage II and III patients. Studies indicate that microarray gene expression profiles can predict survival in CRC. We hypothesize that tumor gene expression in combination with clinical parameters, is a better predictor of outcome in stage II and III colorectal cancers than the TNM stage classification alone. Clinical records and follow-up data were retrospectively reviewed for 58 Stage II and Stage III patients with primary colorectal cancer, who did not receive any neoadjuvant therapy …

Folk Wiki: The Shared Traditions Of Folk Music And The Wiki Way, Phillip Mark Chamberlin

USF Tampa Graduate Theses and Dissertations

Wiki is often perceived as representing a revolutionary break from conventional notions of authorship, writing, and textual history. Dialogues concerning Wiki tend to ignore the characteristics that Wiki shares with earlier forms of collaboration, particularly folk music. In both Wiki and folk music, content is often collectively shared and authored, even if specific individuals create and change the content. Many collaborators are anonymous, quasi-anonymous, or pseudo-anonymous, but the perception of this anonymity is, in both genres, problematic. Second, both Wiki documents and folk songs exist in the "Eternal Now," a seemingly perpetual state that makes these texts available for addition, …

Monitoring And Modeling Water Quality At The C.W. Young Regional Reservoir, Daniel Robert Dye

USF Tampa Graduate Theses and Dissertations

This work explores the relationship between nutrient loading and changes in water quality in a sub-tropical, above-ground, off-stream municipal water supply reservoir, the C.W. Bill Young Regional Reservoir. The three source waters for the reservoir have varied but high levels of nutrients such as phosphorus and nitrogen. In other reservoirs, these nutrients have been linked to deterioration of water quality and increased expense in water treatment. The need to minimize excess nutrients results led to the primary research question: what allocation of withdrawals from the three sources will minimize the deterioration of water quality? To answer this question, the relationship …

Measuring Culture: The Development Of A Multidimensional Culture Scale, Haitham A. Khoury

USF Tampa Graduate Theses and Dissertations

Fundamental to the debate of culture and its impact is the identification of the dimensions that comprise it. The impact of culture as an explanatory variable can be found in various social, scientific, and economic arenas, such as social perception, economic development, and the organization of industries and companies. By identifying and measuring these dimensions, researchers can then organize cultures empirically and develop complex descriptions of various cultures. The study aimed to test the structure of the dimensions proposed by Ho and Chiu (1994) by means of scale development. Test-item writers involved psychology graduate students of various nationalities with the …

Content Differences Between Print And Online Newspapers, Jessica E. Smith

USF Tampa Graduate Theses and Dissertations

The Internet provides the opportunity to develop a new way to present journalism, but many scholars say newspaper Web sites do nothing but mirror their print parents. This study used content analysis to compare the content of stories in five newspapers with their Web counterparts, and it examines whether reporter affiliation or a story's geographic emphasis has a relationship with the story's amount of contextual elements. These elements could include photos, graphics, or multimedia or interactive components online. This approach applied gatekeeping theory to publications that have editions in two media.

This study examined the five largest newspapers in the …

Cognitive Dissonance In Early Colonial Pictorial Manuscripts From Central Mexico, Lorena Diane Mihok

USF Tampa Graduate Theses and Dissertations

This thesis examines the relationship between the imagery and glosses displayed on folios from the Codex Telleriano-Remensis, the Codex Magliabechiano, and the Codex Ixtlilxochitl through the application of Leon Festingers concept of cognitive dissonance in order to introduce an alternative approach to the study of codices as points of culture contact. The work analyzes the ways in which this psychological condition manifested itself in post-contact codex production as a result of sixteenth century political and social circumstances.

Festinger (1957:14) identifies the existence of cultural mores as a source of potential dissonance between culturally specific consonant elements. According to …
