Pce Groundwater Quality Assessment Of The University Of Northern Iowa Campus Area, Brian Gedlinske

Graduate Research Papers

Perchloroethylene (PCE), is a colorless, nonflammable, and relatively insoluble chlorinated solvent once widely used for dry cleaning and metal degreasing operations. Because of its past widespread use, poor solvent management practices, and environmental persistence, PCE is a common contaminant found in groundwater supplies. Potential health concerns include liver problems and increased cancer risk.

This research paper presents the findings of an effort to better characterize the spatial, temporal, and transport attributes of a PCE groundwater plume that exists within the Devonian aquifer underlying the University of Northern Iowa campus and the surrounding area in Cedar Falls, Iowa. Findings reveal the …

Statistical Analysis And Modeling: Cancer, Clinical Trials, Environment And Epidemiology., Dimitrios Vovoras

USF Tampa Graduate Theses and Dissertations

The current thesis is structured in four parts. Vector smoothing methods are used to study environmental data, in particular records of extreme precipitation, the models utilized belong to the vector generalized additive class. In the statistical analysis of observational studies the identification and adjustment for prognostic factors is an important component of the analysis; employing flexible statistical methods to identify and characterize the effect of potential prognostic factors in a clinical trial, namely "generalized additive models", presents an alternative to the traditional linear statistical model. The classes of models for which the methodology gives generalized additive extensions include grouped survival …

The Clash Of Heritage And Development On The Island Of Roatã¡N, Honduras, Alejandro J. Figueroa

USF Tampa Graduate Theses and Dissertations

The present study examines the spatial relationship between archaeological sites on the island of Roatán, Honduras and their topographical and biophysical location, as well as how these relationships are and continue to be impacted by the island's current socioeconomic context. Despite several studies and explorations conducted on the island's history, archaeology, and geography since the early twentieth century, little is known of its place and role within the larger cultural and socioeconomic spheres of interaction in this region: Mesoamerica and the Intermediate Area. Previous archaeological research has shown that hilltops on Roatán were chosen in prehispanic times for the location …

Examining Reasons For Bottled Water Consumption: A Case Study In Pensacola, Florida, Marina Leigh Foote

USF Tampa Graduate Theses and Dissertations

Over-consumption in developed economies undoubtedly puts a large strain on the environment, and many would argue that the damage is irreversible. Current uses and rates of consumption of freshwater resources are also deemed to be unsustainable. A large contributor to the high demand for water is the shift in consumer preferences from tap to bottled water. In the last few decades, bottled water companies have set unprecedented records, surpassing all other types of non-alcoholic beverages to become the second largest beverage market next to soda. Bottled water has been on the rise due to its supposed safety, purity and convenience. …

A total of 467 electrofishing transects were sampled biannually from spring 2008 to spring 2010. Sampling sites ranged from the headwaters of the Peace River in Polk County, FL to the oligohaline waters located in Charlotte County, FL. All fish were collected with boat mounted electrofishing gear, and aquatic habitat and physiochemical water quality measurements were recorded at …

Constructing Alternative Christian Identity: An Ethnography Of Jesus People Usa's Cornerstone Festival, Brian Johnston

USF Tampa Graduate Theses and Dissertations

This dissertation examines processes through which alternative Christian identities are constructed, maintained, and performed at the annual Cornerstone Festival in Bushnell, Illinois. Organized and managed by Jesus People USA (JPUSA), an urban commune in Chicago, Illinois, the festival includes non-traditional methods of religious expression including rock music, making camp, play, and community-building. Cornerstone Festival attracts and includes members of the Christian faith who would not otherwise be included in traditionally organized Christian groups and fosters interaction between these less enfranchised members and more traditionally minded and socialized Christian practitioners. JPUSA appropriates the festival format as a method of religious expression …

Evaluating The Effects Of Beach Nourishment On Loggerhead Sea Turtle (Caretta Caretta) Nesting In Pinellas County, Florida, Corey R. Leonard Ozan

USF Tampa Graduate Theses and Dissertations

The health of Florida's beaches are vital to the survival of loggerhead sea turtles (Caretta caretta), as nearly half of the world's loggerheads nest on the states beaches. Many of the beaches utilized by the turtles have undergone nourishment projects in hopes of combating erosion of the shoreline, protecting beachfront property, and creating more suitable beaches for tourism. Although it is argued that beach nourishment benefits sea turtles by providing more nesting habitat, the effects of the Pinellas County nourishment projects on loggerhead nesting are unknown. Beach nourishment can alter the compaction, moisture content, and temperature of the sand, all …

Speleothems In The Dry Cave Parts Of The Gamslöcher-Kolowrat Cave, Untersberg Near Salzburg (Austria), Anna Bieniok, Georg Zagler, Uwe Brendel, Franz Neubauer

International Journal of Speleology

New, remarkably dry parts of the Gamslöcher-Kolowrat Cave at 728 to 853 m depth have been explored in the Untersberg near Salzburg in Austria. This region is called the Desert, its greatest cavity is called the White Hall. The new cave part is characterized by various white speleothems. The predominant ones are snow-like calcite powder with an extremely low density, and fine gypsum needles. Gypsum also occurs in the form of balls stuck to vertical walls. In addition, fluorescent hydromagnesite crusts, Mg₅(CO₃)₄(OH)₂·4H₂O, as well as the sodium sulfate mineral mirabilite …

Iron Oxide And Calcite Associated With Leptothrix Sp. Biofilms Within An Estavelle In The Upper Floridan Aquifer, Lee J. Florea, Chasity L. Stinson, Josh Brewer, Rick Fowler, B Joe Kearns, Anthony M. Greco

International Journal of Speleology

In Thornton’s Cave, an estavelle in west-central Florida, SEM, EDS, and XRD data reveal biofilms that are predominantly comprised of FeOOH-encrusted hollow sheaths that are overgrown and intercalated with calcite. Fragments of this crystalline biofilm adhere to the walls and ceiling as water levels vary within the cave. Those on the wall have a ‘cornflake’ appearance and those affixed to the ceiling hang as fibrous membranes. PCR of DNA in the active biofilm, combined with morphologic data from the tubes in SEM micrographs, point to Leptothrix sp., a common Fe-oxidizing bacteria, as the primary organism in the biofilm. Recent discoveries …

Theoretical Considerations For Understanding Technological Pedagogical Content Knowledge (Tpack), Charles R. Graham

Faculty Publications

The technological pedagogical content knowledge (TPACK) framework is increasing in use by educational technology researchers around the world who are interested in issues related to technology integration. Much that is good can be found in the TPACK framework; however considerable theoretical work needs to be done if TPACK research is to cohere and constructively strengthen the field of educational technology. This paper uses Whetten’s (1989) criteria for theory building as a lens for examining the TPACK framework. Specific weaknesses are identified, which in turn suggest areas needing theoretical development. This paper calls for researchers to increase emphasis on using research …

Reconciling The Controversy Of Animal Cruelty And The Shoah: A Look At Primo Levi's Compassionate Writings, Ilona Klein

Faculty Publications

Is it ethically admissible to compare the suffering of Jews during World War II to the general suffering of animals in the Western world? Who considers this parallel to be morally obscene, and who supports the comparison? Based on the historical evidence of Nazis insulting Jews with animal verbiage and herding them into the gas chambers of concentration camps, this study looks at a few textual examples by the Italian Jewish author Primo Levi, finding a conciliatory position in his poetry and prose.

Framing 10/12 And 3/11 In American And European News, Andrea Lypka

USF Tampa Graduate Theses and Dissertations

This media analysis of the incidents in Bali in 2002 (10/12) and Madrid in 2004 (3/11) reveals the black and white portrayal of these attacks in western news through the localization of international terrorism occurrences, pro-government perspective, and internalization of U.S. policies. The Old Europe and New Europe debate further fractures the European press. Such rhetoric perpetuates the "us versus them" schism by contrasting the goals of the alleged perpetrators with the western values of democracy and freedom. Governmental sources remain central news sources during these crises. In addition, 9/11, war on terrorism, and fear from further attacks dominate news …

The Role Of Nature In John Muir's Conception Of The Good Life, Randy R. Larsen

Antioch University Dissertations & Theses

Aristotle says our best moral guidance comes from considering the lives of exemplary individuals. I explore John Muir, as an exemplar of environmental virtue, and consider the role of Nature in his conception of the good life. I argue his conception consists of a web of virtue including various goods, values, and virtues. I suggest three virtues are cardinal: attentiveness, gratitude and reverence. I explore how Muir cultivated these virtues in Nature.

I argue Muir sought freedom from a popular conception of the good life, grounded in the gilded age values of money and materialism, and was sensitive to the …

Dormant Ethnobotany: A Case Study Of Decline In Regional Plant Knowledge In The Bull Run Mountains Of Virginia, Susan Rene Leopold

Antioch University Dissertations & Theses

This dissertation introduces and applies the concept of dormant ethnobotany, a concept that helps explain the socio-economic, cultural and ecological aspects and implications of the transition away from active use of ethnobotanical knowledge and the factors that may lead to its re-emergence. Dormant ethnobotany is the study of relationships between people and plants that are inactive, but nonetheless still alive in memories, the historic record, and folklore and thereby capable of reemergence in support of the transition to a more sustainable society. The dissertation extends the field of ethnobotany from its current roots in the dynamic ethnobotany of indigenous peoples. …

Socio-Economic Stability And Independence Of Appalachian Women, Michele Dawn Kegley

Antioch University Dissertations & Theses

This study researched Appalachian women who were in emotional, social, or economic reliant relationships with male spouses and became socio-economically stable and independent. This effort is to give Appalachian women voice and learn from their accounts of how they led change by financially, physically, and socially providing for themselves and their dependent children. Research is limited to a particular group of white middle class Appalachian women in the North-Central sub-region of Appalachia. This group was chosen because they have been largely overlooked in the literature. However, this study does not answer questions of all women‘s experiences and barriers in Appalachia. …

Dual Consciousness: Identity Construction Among Appalachian Professional Women In Southern Ohio, Rebecca Nicole Roades

Antioch University Dissertations & Theses

This study examined identity construction among a purposeful sample of professional women of Appalachian origin with particular regard to the blending of their cultural heritage in a society in which they are often marginalized. The questions guiding the research were grounded in a conceptual framework encompassing elements of culture, gender, leadership, and identity theories specifically using internal colonization, social cognitive, and social identity theories. They included the following: How do these women identify with their Appalachian heritage? How has their Appalachian heritage influenced real or perceived feelings of marginalization and how has that shaped their identity? Do they perceive themselves …

“Voluntary Sector-Rich” And “Voluntary Sector-Poor”: What Difference Does The Distinction Really Make?, Lindsey M. Mcdougle Phd

Dissertations

Nonprofit organizations serve a distinctive role within American society. Collectively, nonprofits are viewed as major sources of social capital, contributors to the public good, and the value guardians within communities. Nonprofits also have a sizeable (and quite positive) impact on the nation's economy. Despite the social and economic significance of nonprofits, though, research has shown that nonprofit organizations and resources are not always distributed evenly across communities. Indeed, Wolch (1990) has observed that some communities are voluntary sector-rich, while others are voluntary sector-poor. Therefore, many of the benefits often associated with the presence of nonprofits may not be actualized, or …

The Curious Case Of Greening In Carbon Markets, James Salzman, William Boyd

Faculty Scholarship

Over the last several years, so-called carbon markets have
emerged around the world to facilitate trading in greenhouse gas
credits. This Article takes a close look at an unexpected and
unprecedented development in some of these markets—premium
“green” currencies have emerged and, in some cases, displaced
standard compliance currencies. Past experiences with other
environmental compliance markets, such as the sulfur dioxide and
wetlands mitigation markets, suggest the exact opposite should be
occurring. Indeed, buyers in such markets should only be interested in
buying compliance, not in the underlying environmental integrity of the
compliance unit. In some of the compliance carbon …

Implications for counselors are discussed.

3d Seismic, Attribute-Assisted, Structural Interpretation For Hydrocarbon Exploration And Production: Southwest Pennsylvania, Central Appalachian Basin, Thomas Bradley Donahoe

Graduate Theses, Dissertations, and Problem Reports (ETD)

High quality 3D seismic data provides critical information vital to the delineation of structural fabrics and depositional facies, and it is therefore important to the development of ideas associated with structural and facies architecture and growth history of the Appalachian foreland basin. Traditional wiggle trace imagery is limited by its dominant frequency and low signal-to-noise ratio; while conventional seismic attributes, such as instantaneous amplitude, RMS and frequency methods are not effective at defining fracture intensity and orientation and spatial and temporal relations between faults and folds which are crucial in achieving the hydrocarbon exploration objective in the basin. To overcome …

Bashkirs Between Two Worlds, 1552-1824, Mehmet Tepeyurt

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation examines the transformation of the Bashkir society from a nomadic and semi-nomadic society to a sedentary society under the Russian empire's control from the sixteenth to the early nineteenth centuries. In particular, it analyzes inter-ethnic relations and the consequences of these relations for both Bashkirs and other peoples in Bashkiria.;The historical Bashkir lands formed Russia's southeastern frontier for more than two hundred years and the penetration of non-Bashkir groups into the region was a slow and arduous process. On the one hand, the region was an extremely dangerous place: the nomadic groups were quite hostile to the arrival …

Formulating A Conceptual Framework To Understand Native American Perceptions Of Place And Identity: A Temporal Examination Of The Spatio-Social Effects Of Uneven Development Through Accumulation By Dispossession, Denyse Wyskup

Graduate Theses, Dissertations, and Problem Reports (ETD)

This research dialectically conceptualizes how capitalist uneven development and subsequent occurrences has shaped, and continues to shape, Native American perceptions of place and identity. Specifically, this research focuses on accumulation by dispossession, a key component of uneven development, and the spatio-historic effects this form of dispossession has had on Native American lifeworlds. This research focuses primarily upon federal legislation in the form of treaties, acts, and court rulings as the predominant component sustaining accumulation by dispossession and, in turn, perpetuating uneven development within Native American communities. In order to more holistically conceptualize the impacts of accumulation by dispossession three Native …

Evaluation Of Species Distribution Model Algorithms For Fine-Scale Container-Breeding Mosquito Risk Prediction, C. Khatchikian, Florencia Sangermano, D. Kendell, T. Livdahl

Geography

The present work evaluates the use of species distribution model (SDM) algorithms to classify high densities of small container-breeding Aedes mosquitoes (Diptera: Culicidae) on a fine scale in the Bermuda Islands. Weekly ovitrap data collected by the Department of Health, Bermuda for the years 2006 and 2007 were used for the models. The models evaluated included the algorithms Bioclim, Domain, GARP (genetic algorithm for rule-set prediction), logistic regression and MaxEnt (maximum entropy). Models were evaluated according to performance and robustness. The area under the receiver operating characteristic curve was used to evaluate each model's performance, and robustness was assessed according …

Theorizing Practice In Economic Geography: Foundations, Challenges, And Possibilities, Andrew Jones, James T. Murphy

Geography

Over the last decade or so there has been an identifiable shift in the interests of many economic geographers towards a concern with practices: stabilized, routinized, or improvised social actions that constitute and reproduce economic space, and through and within which socioeconomic actors and communities embed knowledge, organize production activities, and interpret and derive meaning from the world. Although this shift has gained significant momentum its general theoretical significance remains somewhat unclear and the concept is vulnerable to criticisms that it is incoherent, too 'micro-scale' in emphasis, unable to provide valid links between everyday practices and higher-order phenomena (eg, institutions, …
