Charaterization Of Asbestos Exposure Among Automotive Mechanics Servicing And Handling Asbestos-Containing Materials, Gary Scott Dotson Jan 2006

Charaterization Of Asbestos Exposure Among Automotive Mechanics Servicing And Handling Asbestos-Containing Materials, Gary Scott Dotson

USF Tampa Graduate Theses and Dissertations

The historic use of asbestos-containing materials during the manufacturing of automobiles has resulted in a perception of an increased risk of asbestos-related pulmonary diseases within mechanics. This study was conducted to assess the potential asbestos exposures mechanics encounter while servicing vehicles assembled with parts containing asbestos, in addition to compare the cumulative lifetime asbestos exposures for different maintenance activities against theorical threshold exposures for asbestosis, lung cancer and mesothelioma. Exposure data were assembled from four independent exposure assessments performed to elucidate the airborne asbestos levels generated during the removal and replacement of brakes, gaskets, clutches and seam sealants containing asbestos. …


Control Of Lysogeny In Marine Bacteria: Studies With Φhsic And Natural Populations, Amy K. Long Jan 2006

Control Of Lysogeny In Marine Bacteria: Studies With Φhsic And Natural Populations, Amy K. Long

USF Tampa Graduate Theses and Dissertations

Viruses have an estimated global population size of 10 to the 31st, with a significant proportion found in the marine environment. Viral lysis of bacteria affects the flow of carbon in the marine microbial food web, but the effects of lysogeny on marine microbial ecology are largely unknown. In this thesis, factors that influence the control of lysogeny were studied in both the phiHSIC/Listonella pelagia phage-host system and in bacterioplankton populations in the Gulf of Mexico. Using macroarrays dotted with phiHSIC amplicons, viral gene expression over the course of a synchronous infection experiment was measured. Early, middle, late, and continually …


Precipitation Variability Of Streamflow Fraction In West Central Florida, Michael H. Scott Jan 2006

Precipitation Variability Of Streamflow Fraction In West Central Florida, Michael H. Scott

USF Tampa Graduate Theses and Dissertations

There is a strong interest to develop a method to estimate mean annual ungaged streamflow with varying precipitation. A method was developed utilizing GIS and other statistical analysis to estimate ungaged mean annual streamflow. This method utilizes a normalized streamflow fraction (NSF) method previously developed which relies on drainage basin area, coupled with mean annual local precipitation, to estimate the ungaged streamflow variability. This method has been applied to west central Florida.The test of the method yielded an R squared value of 0.9894, proceeded by a verification that yielded an R squared value of 0.998. This method is believed to …

Travel Assistant Device (Tad) To Help Transit Riders, Philip L. Winters, Sean Barbeau, Nevine Georggi, Rafael Perez, Miguel Labrador

CUTR Research Reports

This proposed application, Travel Assistance Device (TAD), would use multimedia cell phones with built-in global positioning systems to help new transit riders, especially those who are cognitively disabled. Informational prompts will be delivered to the rider in a "just-in-time" method such as triggering the phone to ring, vibrate or deliver an audio message when the rider should pull the stop cord. Automated alarms can be triggered and the travel trainer and/or parent/guardian remotely alerted in case a rider wanders off their pre-determined path. Traditional phone communication is possible between the rider and the trainer which will allow them to guide …

A Lesson Plan On Fungi Diversity For The Centro De Educación Creativa, November 2005, Rachel Deliz Nov 2005

A Lesson Plan On Fungi Diversity For The Centro De Educación Creativa, November 2005, Rachel Deliz

Monteverde Institute: Tropical Ecology and Conservation

Fungi are integral components of a forest environment, but they are often overlooked in elementary education, despite their crucial role in nutrient cycles. Concepts pertaining to fungi diversity were researched and compiled to be part of the 5th grade curriculum of Centro de Educación Creativa. The result of this project was three PowerPoint presentations, each coupled with 2-3 visual aids, experiments and/or activities. I expect these presentations to aid in the environmental education curriculum at the C.E.C and to promote an appreciation of the Kingdom Fungi.


Modeling Hurricane Evacuation Vulnerability: A Case Study Of Pinellas County, Florida, Raymond A. Miller Jr. Oct 2005

Modeling Hurricane Evacuation Vulnerability: A Case Study Of Pinellas County, Florida, Raymond A. Miller Jr.

USF Tampa Graduate Theses and Dissertations

Determining where people are most likely to suffer losses and have difficulty in evacuating from a hurricane is important to developing a hurricane response strategy. This thesis proposes a methodology for modeling and assessing evacuation vulnerability to a specific hurricane and applies this method to study Pinellas County, Florida.

The vulnerability of Pinellas County to evacuation problems and the degree of loss that may be suffered from a hurricane is quantified in the Hurricane Evacuation Vulnerability Index. This index is the sum of three indices that represent social, transportation, and geophysical aspects of hazards research. Social vulnerability is assessed with …

Effects Of Detritus Abundance And Diversity On The Composition Of Detritivore Communities Within Tank Bromeliads, May 2005, Callie Brown May 2005

Effects Of Detritus Abundance And Diversity On The Composition Of Detritivore Communities Within Tank Bromeliads, May 2005, Callie Brown

Monteverde Institute: Tropical Ecology and Conservation

Detritivores are important in the cycling of nutrients within bromeliads as they help release nutrients from detritus, making them available to the plant. This study set out to explore how the amount and diversity of detritus influenced the detritivore community structure within bromeliads. Results indicated that a greater amount of detritus supported a greater number of detritivore individuals and by some indices, a richer detritivore community. However, detritus diversity appeared to have no significant effect on the richness or abundance of detritivores. This could indicate that detritus is in fact a homogeneous resource and resource partitioning is not occurring among …

Choosing Your Baseline Carefully: Integrating Historical And Political Ecology In The Evaluation Of Environmental Intervention Projects, Danny De Vries Jan 2005

Choosing Your Baseline Carefully: Integrating Historical And Political Ecology In The Evaluation Of Environmental Intervention Projects, Danny De Vries

Journal of Ecological Anthropology

Environmental intervention projects aim to re-engineer the cultural landscape. Entering at a particular moment in time, such projects commonly produce a "baseline" analysis. This analysis captures elements in the environment that are later compared to measured changes the project claims to produce. Illustrated through a case study of a Tanzanian community conservation non-governmental organization, the argument made in this paper is that uncritical use of such baselines in measuring and evaluating environmental intervention projects is a practice that tends to impose ahistorical understandings of human-environmental relationships that have deep historical roots. The paper illustrates how an attempt to draw a …


Migration And Home Gardens In The Brahmaputra Valley, Assam, India, Rahul J. Shrivastava, Joel T. Heinen Jan 2005

Migration And Home Gardens In The Brahmaputra Valley, Assam, India, Rahul J. Shrivastava, Joel T. Heinen

Journal of Ecological Anthropology

The Brahmaputra is the largest river system in northeast India. Its valley, in the State of Assam, is home to the Assamese people, indigenous Mishing and Karbi tribes, and Kaziranga National Park. A spectacular array of wildlife shares the floodplain including the endangered Asian elephant, tiger, one-horned rhinoceros and wild buffalo. The fertile floodplain and tea estates have attracted immigrants from within India and from neighboring countries. Migration has been linked to Assam's high population density and agriculture expansion. Based on household surveys in 37 villages in the park's periphery, we compared home garden productivity and economic return among residents …


All The News That’S Fit To Print? Media Reporting Of Environmental Protection Agency Penalties Assessed Against The Petroleum Refining Industry, 1997-2003, Melissa L. Jarrell Jan 2005

All The News That’S Fit To Print? Media Reporting Of Environmental Protection Agency Penalties Assessed Against The Petroleum Refining Industry, 1997-2003, Melissa L. Jarrell

USF Tampa Graduate Theses and Dissertations

Although examination of the relationship between the media and crime has received considerable attention in the academic literature, only a few studies have examined news media coverage of environmental crimes. The present study examines print news media coverage of federal penalties assessed against the petroleum refining industry from 1997 to 2003. The Environmental Protection Agency initiated and/or settled 162 cases involving seventy-eight petroleum refining companies from 1997 to 2003. While a news search of the nation’s twenty-five largest newspapers produced seventy-four articles related to petroleum refining industry violations, only seventeen articles matched the EPA cases analyzed in the present study. …

A Co-Orientational Analysis Of Public Involvement Perceptions In The Transportation Process: A Case Study, Kristen E. Carson Jan 2005

A Co-Orientational Analysis Of Public Involvement Perceptions In The Transportation Process: A Case Study, Kristen E. Carson

USF Tampa Graduate Theses and Dissertations

This study explored public involvement within the Florida Department of Transportation (FDOT) using the co-orientational theory. Effective public involvement gives the public opportunities to be involved early in the planning and implementation of transportation projects that directly affect or may concern them. The co-orientational model looks at what an organization (FDOT) thinks about an issue (public involvement), what the public thinks of the issue, what the organization thinks the public thinks about the issue, and what the public thinks the organization thinks about the issue.

This study investigated whether the FDOT management has an accurate understanding of the perceptions of …

The Effects Of Edge And Pollution On Lichen Richness, Abundance, And Distribution In Cañitas, Costa Rica, November 2004, Jenny Bedell-Stiles Nov 2004

The Effects Of Edge And Pollution On Lichen Richness, Abundance, And Distribution In Cañitas, Costa Rica, November 2004, Jenny Bedell-Stiles

Monteverde Institute: Tropical Ecology and Conservation

Lichens are commonly known to be biological indicators of pollution and edge effects. Their use as indicators in temperate regions is well documented, however, less is known about their function as a bioindicator in the tropics. There is also debate over the consequences of edge effects, such as increased temperature, and less moisture and wind, on lichen richness and abundance. In this study lichen communities on tree trunks in three habitat sites (primary forest, pasture, and roadside) were examined. In total 88 trees were censused in order to determine lichen richness, abundance, and similarity. Overall 68 species of lichen were …


A Comparison Of Moth Diversity And Abundance Along An Altitudinal Gradient In Monteverde, Costa Rica, August 2004, Katie Swartz Aug 2004

A Comparison Of Moth Diversity And Abundance Along An Altitudinal Gradient In Monteverde, Costa Rica, August 2004, Katie Swartz

Monteverde Institute: Tropical Ecology and Conservation

Costa Rica has high moth (Lepidoptera) diversity, with relatively little known about its distribution (Hanson 2000). Insects tend to decrease in richness and abundance along an altitudinal gradient (Brehm and Fiedler 2003). Lepidopterans are important indicators of environmental health, important herbivores, vital prey species, and a large draw for the country’s main source of income, ecotourists. The purpose of this study was to compare moth diversity and abundance at varying altitudes. Moths were trapped using an ultra violet light and a sheet at three different altitudes (1530 m, 1639 m, and 1759 m) over six nights between July 26th and …


Recycled Materials Relational Database: Design And Implementation Aspects, Rory Morgan Mcdonald Jun 2004

Recycled Materials Relational Database: Design And Implementation Aspects, Rory Morgan Mcdonald

USF Tampa Graduate Theses and Dissertations

Although there has been a rise in the use of recycled materials in highway and geotechnical systems, many tons of potentially useful industrial and domestic by-products are still being discarded in the United States each year. While extensive research has been conducted to investigate the use of recycled materials in engineering applications, the dissemination of the findings is often limited. The problem is compounded by the lack of a single resource containing relevant engineering and environmental characteristics of each material; the tendency of the researchers to publish their findings in technical reports rather than archived publications; and the wide discrepancies …
