A Geochemical Analysis Of Fulgurites: From The Inner Glass To The Outer Crust, Michael L. Joseph

USF Tampa Graduate Theses and Dissertations

Cloud-to-ground lightning strikes produce natural glasses on the surface of the Earth, called fulgurites. These natural glasses are tubular in shape with a central void surrounded by an inner glass, and the inner glass is surrounded by an outer crust or toasted region. Previous studies report different kinds of melts existing in several different types of fulgurites; however, little to no chemical data has been collected that tracks chemical variations from the inner glass to the outer crust of a fulgurite. This study uses microprobe and laser ablation inductively coupled plasma mass spectrometer analytical techniques to collect transects of chemical …

Transformation Of Stimulus Function Through Relational Networks: The Impact Of Derived Stimulus Relations On Stimulus Control Of Behavior, Samantha Rose Florentino

USF Tampa Graduate Theses and Dissertations

Relational Frame Theory research involves either of two protocols utilized to establish relational networks and functions for stimuli in those relational networks. Years of research indicate the most prevalent method involves first establishing a relational frame, conditioning one of the stimuli to acquire a particular function, and then providing a test to see if the function trained to one of the stimuli in the network transferred through the relational network to other stimuli. The less common method involves first training a particular function for a stimulus, entering that stimulus in a relational network with at least two other stimuli, and …

The Walls Are Closing In: Comparing Property Crime Victimization Risk In Gated And Non-Gated Communities, Nicholas Branic

USF Tampa Graduate Theses and Dissertations

In recent years, a growing proportion of the population has moved into gated communities in response to an increasingly pandemic fear of crime. While a sizable body of research has addressed fear of crime and perceived safety in gated communities, few studies have investigated actual rates of victimization. The studies that do compare victimization in gated and non-gated communities tend to be localized assessments and present mixed findings on the effectiveness of community gating as a form of protection from crime.

The present study utilizes a cross-section of National Crime Victimization Survey data to investigate the micro-level effects of living …

World Percussion Approaches In Collegiate Percussion Programs: A Mixed-Methods Study, Patrick Michael Hernly

USF Tampa Graduate Theses and Dissertations

As world percussion has grown in popularity in American colleges and universities, two main problems have emerged. The first problem is that no known source exists detailing how percussion instructors have incorporated world percussion into their collegiate teaching. A review of the literature has highlighted four main approaches to incorporating world percussion in collegiate percussion programs: applied study, group performance, travel experiences, and guest expert visits. The second problem is that systematic research on world percussion traditions has been carried out much more often by music education researchers, anthropologists, and ethnomusicologists than by percussionist-performers, so the relationship between theory and …

Implementation And Optimization Of An Inverse Photoemission Spectroscopy Setup, Ervin Gina

USF Tampa Graduate Theses and Dissertations

Inverse photoemission spectroscopy (IPES) is utilized for determining the unoccupied electron states of materials. It is a complementary technique to the widely used photoemission spectroscopy (PES) as it analyzes what PES cannot, the states above the Fermi energy. This method is essential to investigating the structure of a solid and its states. IPES has a broad range of uses and is only recently being utilized.

This thesis describes the setup, calibration and operation of an IPES experiment. The IPES setup consists of an electron gun which emits electrons towards a sample, where photons are released, which are measured in isochromat …

Learning Without Being Taught: A Look At How Schools, The Home And The Neighborhood Influence "Race" Conceptualization, Owen Christopher Gaither

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Where do we get our ideas about the concept of `race'? The conceptualization of `race' has long been a topic of interest in the social sciences and society in general. The word `race' has been used and defined in different ways and different purposes throughout U.S. history. The definition of `race' therefore is arbitrary, changing according to the situation, but the consequences of how the word `race' is used are concrete and effect peoples lives daily. This research, in accord with much of the literature on the topic, shows that public schools play a major role in the conceptualization …

Further, research indicates the addition of an in situ assessment promotes generalization of trained skills. The current study examined the use …

Toward A Working Theory Of Neurorhetorics, Jeffrey L. Honnold

USF Tampa Graduate Theses and Dissertations

This piece makes the claim that rhetoric is first philosophy--before philosophy, epistemology, ontology, or any other field--or that rhetoric is, at the least, on equal footing as these fields because:

empathy--and thusly the impulse for communication--is physiologically hardwired into humans; special distinctions between human and animal are largely artificial constructions, as is evidenced by neurosciences; "hard" science, in the form of neurosciences, is providing entrance points & opportunities for rhetoric to raise its status within the academy; and said neurosciences, in addition to empathy studies, have shown strong evidence supporting linguistic and evolutionary links between humans and other species, thereby …

Bradenton, Fl: A Patchwork City, Rebekah G. Brightbill

USF Tampa Graduate Theses and Dissertations

The City of Bradenton is a patchwork city, whose neighborhoods vary greatly in quality. While its neighborhoods differ in type based on consumer preference, they vary in quality because of federal, state, and local planning and urban policy. These policies have resulted in inequality of place and race, clustering racial minorities in center city neighborhoods with deteriorated infrastructure and income inequality. This impacts the ability of the City to be competitive with other cities as a metropolitan whole. The City's economically and racially segregated neighborhoods are not the inevitable outcome of market forces, but rather reflect decades of federal, state, …

Essays On Mental Accounting And Consumers' Decision Making, Ali Besharat

USF Tampa Graduate Theses and Dissertations

This dissertation is structured in the form of two empirical essays, each investigating one type of irrational decision caused by mental accounting. The first essay, titled "Managing the Cost of Multiple Debt Accounts: A Behavioral Perspective", explores why many people pay off credit cards' with the lowest rate first when rationally speaking they should repay the debt with the highest rate most quickly. This essay suggests that irrationality emerges when people seek to close `mental accounts' associated with their credit cards and reduce the total number of outstanding loans rather than decrease the amount of total debt among all credit …
