Examining The Economic Costs And Sources Of Potable And Nonpotable Water In Northern Mexico, Kathryn Marie Marlor

USF Tampa Graduate Theses and Dissertations

Water availability and the cost of different water sources have been studied at great length. However, information is still needed to determine the policy directions to be undertaken by nations that have not yet achieved universal coverage of an improved water source. To further examine differences in water availability and pricing in the context of the developing world, three communities in Northern Mexico were surveyed to determine the differences in water distribution schemes and associated costs between rural and urban centers. It was observed that rural communities without a piped water supply paid 13 percent more for potable water supplies …

Design And Construction Of Functional Metal-Metalloporphyrin Frameworks, Le Meng

USF Tampa Graduate Theses and Dissertations

Porous metal-organic frameworks are a new type of functional materials with potential applications for gas storage, gas separation, catalysis, biomedical and chemical sensors. This thesis describes several porous metal-metalloporphyrin frameworks (MMPFs), which were synthesized with a series of transition metals and 5,15-bis(3,5-dicarboxyphenyl)-10,20-bis(2,6-dibromophenyl)porphine. Among these MMPFs, the cobalt MMPF (CoBrPTC) has a fcu structure, which represents the first porphyrin-based MOF with this topology. CoBrPTC was evaluated as heterogeneous catalyst and demonstrated interesting catalytic performances.

Willingness-To-Pay For Maintenance And Improvements To Existing Sanitation Infrastructure: Assessing Community-Led Total Sanitation In Mopti, Mali, Justin Vern Meeks

USF Tampa Graduate Theses and Dissertations

In recent years, much focus has been put on the sustainability of water and sanitation development projects. Experts in this field have found that many of the projects of the past have failed to achieve sustainability because of a lack of demand for water and sanitation interventions at a grassroots level. For years projects looked to create this demand through various subsidy schemes, with the "software" of behavior change and education taking a backseat to the "hardware" of infrastructure provision. Community-Led Total Sanitation (CLTS) is a fairly new way of looking at the issues of increasing basic sanitation coverage, promoting …

Developing Predictive Models For Lung Tumor Analysis, Satrajit Basu

USF Tampa Graduate Theses and Dissertations

A CT-scan of lungs has become ubiquitous as a thoracic diagnostic tool. Thus, using CT-scan images in developing predictive models for tumor types and survival time of patients afflicted with Non-Small Cell Lung Cancer (NSCLC) would provide a novel approach to non-invasive tumor analysis. It can provide an alternative to histopathological techniques such as needle biopsy. Two major tumor analysis problems were addressed in course of this study, tumor type classification and survival time prediction. CT-scan images of 109 patients with NSCLC were used in this study. The first involved classifying tumor types into two major classes of non-small cell …

Evaluation Of Transfer Technologies To Preserve Shoulder Function In Sci, Karen Michelle Mann

USF Tampa Graduate Theses and Dissertations

This study investigated a series of independent unassisted and device-assisted transfers from a wheelchair to vehicle mock-up and vice versa while simultaneously capturing kinematic, kinetic and electromyographic (EMG) data of impaired volunteers. The study provides a venue for observation and evaluation of upper extremity (UE) joint stresses, muscular force and functional demands associated with transfers in persons with spinal cord injury (SCI) to ultimately prevent UE injury, minimize excessive stress, preserve functionality and limit pain. If people with SCI lose function of their UEs, due to pain and/or degeneration, they must then rely on others for everyday tasks.

Evidence For Viral Infection In The Copepods Labidocera Aestiva And Acartia Tonsa In Tampa Bay, Florida, Darren Stephenson Dunlap

USF Tampa Graduate Theses and Dissertations

Mesozooplankton are of critical importance to marine food webs by transferring energy from the microbial food web to higher trophic levels and depositing energy to the deeper ocean layers through fecal deposition. While decades of research have shown that viruses have significant impacts in the oceans, and infect a wide range of organisms from bacteria to whales, there is still little known about the impacts of viruses on the mesozooplankton community. As copepods are the most abundant mesozooplankton group, this study sought to characterize the viruses present in natural populations of the calanoid copepods Acartia tonsa and Labidocera aestiva in …

Examining The Moderating Role Of Organizational Commitment In The Relationship Between Shocks And Workplace Outcomes, Kyle Groff

USF Tampa Graduate Theses and Dissertations

Little attention has been given to the role organizational commitment plays within broader models of turnover and withdrawal behavior. Understanding and integrating organizational commitment into such models is an important step to fully appreciating the role that commitment plays in the workplace. The purpose of the current study was twofold. First, this study aimed to examine the moderating role that organizational commitment plays in the unfolding model of voluntary turnover. Second, this study set out to examine the role that the various forms of commitment play in the relationship between shocks and withdrawal-related variables. By utilizing a multidimensional model of …

Development Of An Integrated Process Model For Algae Growth In A Photobioreactor, Mehregan Jalalizadeh

USF Tampa Graduate Theses and Dissertations

While understanding the kinetics of algae growth plays an important role in improving algae cultivation technology, none of the existing kinetic models are able to describe algae growth when more than three growth limiting factors are involved. A model was developed in this study to describe algae growth in a photobioreactor. Two expressions were proposed based on the Monod model to relate the specific growth rate of algae to the concentration of nitrogen, phosphorus, inorganic carbon and light intensity in the culture media. Algal biomass concentration as a function of time was calculated by solving mass and energy balances around …

Speaker Recognition Using Shifted Mfcc, Rishiraj Mukherjee

USF Tampa Graduate Theses and Dissertations

Speaker Recognition is the art of recognizing a speaker from a given database using speech as the only input. In this thesis we will be discussing a novel approach to detect speakers. Here we will introduce the concept of shifted MFCC to add improvement over the performance from previous work which has shown quite a decent amount of accuracy of about 95% at best. We will be talking about adding different parameters which also contributed in improving the efficiency of speaker recognition. Also we will be testing our algorithm on Text dependent speech data and Text Independent speech data. Our …

When Bad Things Happen To Good Mothers: Rethinking Motherhood Through The Single Mother Image In American Films From The 1930s To The 1970s, Tanna Alice Mancini

USF Tampa Graduate Theses and Dissertations

ABSTRACT

The single-mother figure shows up in myriad American film genres, and my thesis explores three of these genres, maternal melodrama, film noir, and horror. I argue there is a melodramatic mode that carries over from maternal melodrama to film noir and horror. This mode emphasizes emotional excess. In maternal melodrama, the emotional excess is pity. For film noir, the emotion is anxiety, and in horror, it is repulsion. Even though each genre has its own emotional excess, maternal melodrama still speaks to these other genres through its maternal sacrifice, non-heteronormative families and misreading of proper gender performances. For this …

Out Of Our Depth: Hyper-Extensionality And The Return Of Three-Dimensional Media, Justin Alan Brecese

USF Tampa Graduate Theses and Dissertations

This work theorizes the contemporary attraction to three-dimensional media. In doing so, it reframes ongoing debates surrounding digital three-dimensional media in order to critique the neoliberal social relations such media engender. I argue that the contemporary interest in dimensionality, especially regarding digital media, is symptomatic of a broad cultural shift, wherein millions of lives are now essentially being lived through two-dimensional, "flat" media, which have consequently generated a lack of spatial relationships and a craving or desire for "depth." This "desire for depth" has arisen in contemporary society because people are being "spread too thin" through a combination of the …

Postcolonial Religion And Motherhood In The Novels By Louise Erdrich And Alice Walker, Kateryna Chornokur

USF Tampa Graduate Theses and Dissertations

This thesis is a comparative analysis of the works of the Native American author Louise Erdrich (Love Medicine, Tracks) and the African American writer Alice Walker (The Color Purple). Originating from different cultural traditions, Native American and African American women writers address common themes in their novels because of their common colonial background. One of the main themes in their writings is that of religion. Despite becoming victims of Christianity used as a means of cultural colonization, both African American and Native American communities reinterpret it in terms of their traditional religious beliefs and create a new, unique hybridized form …

An Ecological Assessment Of A Juvenile Estuarine Sportfish, Common Snook (Centropomus Undecimalis), In A Tidal Tributary Of Tampa Bay, Florida, Adam Benjamin Brame

USF Tampa Graduate Theses and Dissertations

The common snook, Centropomus undecimalis, is an estuarine dependent sport fish that relies upon subtidal wetlands as nursery habitat. Despite the economic and recreational significance of this species, there are portions of its life history and biology that are poorly understood, particularly its early life history. Understanding juvenile snook use of wetland habitats is crucial given the rapid loss and degradation of these areas to anthropogenic impacts. Young-of-the-year snook were collected in pond and creek habitats of a single wetland system to assess early life ecology and habitat use. Proxies of habitat quality were used to determine which habitats …

Overcoming Limitations Of Serial Audio Search, Isabela Cordeiro Ribeiro Moura Hidalgo

USF Tampa Graduate Theses and Dissertations

The typical approach for finding audio recordings, such as music and sound effects, in a database is to enter some textual information into a search field. The results appear summarized in a list of textual descriptions of the audio files along with a function for playing back the recordings. Exploring such a list sequentially is a time-consuming and tedious way to search for sounds. This research evaluates whether searching for audio information can become more effective with a user interface capable of presenting multiple audio streams simultaneously.

A prototype audio player was developed with a user interface suitable for both …
