The Conversion Of Low-Grade Heat Into Power Using Supercritical Rankine Cycles, Huijuan Chen

USF Tampa Graduate Theses and Dissertations

Low-grade heat sources, here defined as below 300 ºC, are abundantly available as industrial waste heat, solar thermal, and geothermal, to name a few. However, they are under-exploited for conversion to power because of the low efficiency of conversion. The utilization of low-grade heat is advantageous for many reasons. Technologies that allow the efficient conversion of low-grade heat into mechanical or electrical power are very important to develop.

This work investigates the potential of supercritical Rankine cycles in the conversion of low-grade heat into power. The performance of supercritical Rankine cycles is studied using ChemCAD linked with customized excel macros …

Linking Soil Loss To Sediment Delivery In Two Estuaries In Puerto Rico, Nekesha Bernadette Williams

USF Tampa Graduate Theses and Dissertations

Enhanced soil loss from the watershed is a major environmental issue. Increased soil loss from a watershed can potentially increase sediment delivery and loading to aquatic ecosystems such as rivers and estuaries. An increase in sediment delivery and loading to freshwater and transitional marine ecosystems can impact water quality and supply specifically by: (1) reducing water clarity, (2) transporting nutrient and pollutant laden sediments and (3) reducing the storage capacity of reservoirs. To address these broader environmental impacts of increased sediment delivery and loading to aquatic ecosystems it is imperative that potential source areas of sediments available for transport are …

Through The Lens Of A Global Educator: Examining Personal Perceptions Regarding The Construction Of World-Mindedness, Kenneth T. Carano

USF Tampa Graduate Theses and Dissertations

As we embark upon the 21st century, the world is becoming increasingly interconnected. Yet, despite increasing globalization, educational systems are not reflecting this phenomenon. The overwhelming majority of countries, including the United States, still emphasize nationalistic curricula (Parker, 2008; Tye, 2009). Global education is a movement whose supporters advocate an education reflecting the push towards globalization by providing students with the components necessary to live and thrive in an increasingly interconnected world system. Global educators have a common bond as advocates that a global perspective needs to be developed in the classroom. The degree to which this is being done …

The Interaction Between Urban Form And Transit Travel, Sisinnio Concas

USF Tampa Graduate Theses and Dissertations

This study presents an analytical model of the interaction between urban form and the demand for transit travel, in which residential location, transit demand, and the spatial dispersion of non-work activities are endogenously determined. In this model, travel demand is considered a derived demand brought about by the necessity to engage in out-ofhome activities whose geographical extent is affected by urban form. In a departure from the urban monocentric model, residential location is defined as a job-residence pair in an urban area in which jobs, residences, and non-work activities are dispersed. Transit demand is then determined by residential location, work …

Melville’S Unknown Pathology: The Humoral Theory Of Disease And Low Grade Lead Poisoning In Bartleby The Scrivener, Gerard Bogin

USF Tampa Graduate Theses and Dissertations

Melville wrote Bartleby the Scrivener as a literary portrayal of the Humoral theory of disease. Virchow disproved that theory five years after the novella was published, suggesting Melville was humanizing an unknown pathology. A clinical assessment of the text reveals low-grade lead poisoning, which best explains the strange behavior, abnormal appearance, and premature death of the character Bartleby as depicted by the author. In conjunction with the textual substantiation, historical evidence indicates that at the time Melville wrote the work, one in ten people he encountered suffered from the effects of the same disease. Informed with the identity of Melville’s …

Small Plots, Big Hopes: Factors Associated With Participation In An Urban Garden Project In Lesotho, Charlotte Ann Noble

USF Tampa Graduate Theses and Dissertations

Studies of food insecurity have frequently focused on rural dwellers as vulnerable

populations. However, during the ‘global food crisis’ of 2007-2008, riots in more than

50 countries visibly demonstrated the vulnerability of urban populations to food

insecurity due to rapidly rising food prices. This study examines factors associated with

participation in an urban garden project (UGP), utilizing surveys (n=61) and in-depth

household interviews (n=37) to examine food security and dietary diversity of households

in urban Lesotho.

Households that participated in the garden project were more food insecure and

had lower dietary diversity than those that did not participate. However, it …

The Influence Of Narcissism And Self-Control On Reactive Aggression, Melissa L. Harrison

USF Tampa Graduate Theses and Dissertations

The empirical literature to date has indicated that narcissism is associated with reactive aggression; however, exactly why narcissists respond with aggression to provocation is yet to be determined. The present paper is an exploration of two possible means through which a lack of self-control could be an important predictor involved in narcissists‟ aggressive behavior: 1) a lack of self-control could explain the link between narcissism and aggression, and 2) the combination of insufficient self-control and narcissism could increase the likelihood of aggressive response to provocation.

To explore these possibilities, an experiment was conducted in which 214 participants were first administered …

An Assessment Of Microevolutionary Change Among Prehistoric Florida Populations Through The Analysis Of Craniometric Data, Samantha M. Seasons

USF Tampa Graduate Theses and Dissertations

The analysis of craniometric data collected from skeletal remains, combined with

archaeological data, can provide very valuable information pertaining to biological

distance and gene flow among prehistoric populations through space and time. The goal

of this study was to examine microevolutionary change among prehistoric populations in

south Florida based on the degree of cranial variation among populations at seven

prehistoric sites. It was expected that as time progressed, microevolutionary forces

caused significant changes in the crania of the various populations based on the relative

geographic proximity of the sites and the temporal distance between sites.

School Counselor Accountability Practices: A National Study, Cindy M. Topdemir

USF Tampa Graduate Theses and Dissertations

This study focused on school counselor accountability practices. The role of the

school counselor is changing and the need to be more accountable is now here. This study

attempted to answer several critical questions regarding school counselor accountability.

It examined the degree to which school counselors use accountability measures, to what

extent they believed certain accountability practices were deemed helpful to their school

counseling program, and what they believed their barriers were. Accountability is a “hot”

topic in present school counseling literature; but little research has been done up to this

point investigating these issues related to school counselor accountability …

Angiostatic Regulators In Ovarian Cancer, Christina Diane Drenberg

USF Tampa Graduate Theses and Dissertations

Angiogenesis by either normal or neoplastic cells involves a delicate balance of both angiogenic and angiostatic regulators. In the ovary, normal physiological angiogenesis occurs around the developing follicle and corpus luteum in response to hormonal shifts. Interestingly, carcinomas arising from the ovary are usually highly vascularized and are commonly clinically observed to produce cyst fluids or ascites which contain both angiostatic and/or angiogenic regulators. However, in contrast to normal angiogenesis, angiogenesis associated with epithelial ovarian cancer usually produces aberrant vasculature that may promote neoplastic progression. Therefore, the ovary and ovarian cancers provide models to study the mechanisms governing the strict …

Nautical Knowledge: An Experimental Analysis Of The Influence Of Public Relations Strategies In Safe Boating Communication, Emily N. Guilfoil

USF Tampa Graduate Theses and Dissertations

This study explored the effect of public relations message strategies on beliefs,attitudes, and behavioral intentions of individuals regarding boater safety. An experiment was conducted using seven safety messages. Specifically, Fishbein and Ajzen’s (1975) theory of reasoned action and J.E. Grunig’s (1997) situational theory of publics were used to examine the communication effects of message strategies proposed by Hazleton and Long’s (1988) public relations process model.The findings of this study support the predictions of the theory of reasoned action—that salient beliefs predict attitude toward behavior and attitude toward behavior and subjective norm predict behavioral intent. Of the three attitude items measured—attitude …

Developing A Culturally Responsive Literacy Pedagogy: Preservice Teachers, Teaching Cases, And Postcard Narratives, Annmarie Alberton Gunn

USF Tampa Graduate Theses and Dissertations

The results of the U. S Census provide evidence that our population is becoming more varied and that diversity is most salient in our schools. This demographic shift will continue to have a significant impact on the curriculum, students, teachers, and other aspects of education as we have historically known it. One of the most challenging aspect is that while our students are becoming more diverse, our teacher population is not. Eighty to ninety percent of the teaching population is White, heterosexual, middle class females, with little experiences with people from diverse backgrounds. (Lowenstein, 2009; Sleeter, 2001).

The academic achievement …

A CMOS/CCD camera and lens was used to image the targeted area. In addition, extensive optical ray tracing simulations were made to predict the intensity patterns. The experimental measurements and ray tracing simulations were in good agreement, and indicated that 20 degree cone reflectors for the LED sources …

The Ports Of Tampa And Hamburg And The Qualitative Impacts On Their Communities, Gerhard Becker

USF Tampa Graduate Theses and Dissertations

This study researches the past, present and future role of ports, specifically the Ports of Tampa and Hamburg linked to their cities. It examines the legal structures of port authorities which play a major role in their economic priorities and impact their cities’ social, environmental and cultural quality of life. From a humanistic perspective, one can look at a port as a place or space. By animating ports, they may provide “ fields of care” over time, and a home with character for the region’s residents. In this case, their success needs to transcend economics, adding qualitative attributes to the …

Multi-Elemental Chemical Analysis Of Anthropogenic Soils As A Tool For Examining Spatial Use Patterns At Prehispanic Palmarejo, Northwest Honduras, Kara A. Rothenberg

USF Tampa Graduate Theses and Dissertations

Plazas and patios were important spaces for expressing power and social identity in prehispanic Mesoamerica. However, plazas can be analytically problematic, because they were often kept clean of material debris. Previous geoarchaeological studies of anthropogenic soils and sediments have shown that specific activities leave characteristic chemical signatures on prepared earthen surfaces. The research presented here uses soil chemical residue analysis and excavation data to examine use patterns in the North Plaza of Palmarejo, Honduras during the Late Classic period. The goal is to determine whether the plaza was used for residential or ceremonial purposes. The chemical results indicate that activities …
