Time Wounds All Heels: Human Nature And The Rationality Of Just Behavior, Timothy Glenn Slattery Feb 2014

Time Wounds All Heels: Human Nature And The Rationality Of Just Behavior, Timothy Glenn Slattery

USF Tampa Graduate Theses and Dissertations

We share our world with many people who ignore the principles of justice and who regularly take advantage of others by breaching trust or breaking agreements. This dissertation is about the irrationality of the actions of these covenant-breakers. A covenant-breaker typically believes that unjust behavior is to his advantage and that only a fool would act in any other way. Would it not be disturbing if this were true?

My central claim will be that adherence to the precepts of justice is a rational strategy for a self-interested actor. I intend to demonstrate that con men and covenant-breakers do not …


Public Knowledge And Sentiments About Elite Deviance, Cedric Michel Jan 2014

Public Knowledge And Sentiments About Elite Deviance, Cedric Michel

USF Tampa Graduate Theses and Dissertations

A growing body of research has revealed that the financial cost and physical harmfulness of elite deviance overshadow the impact of street crime on society (Knowlton et al., 2011; Landrigan et al., 2002; Leigh, 2011; Lynch & Michalowski, 2006; Herbert & Landrigan, 2000; Rebovich & Jiandani, 2000; Reiman & Leighton, 2010). However, despite such discrepancies, crimes of the poor continue to outshine white-collar offenses in the news media (Barak, 1994; Barlow & Barlow, 2010; Ericson et al., 1991; Lynch & Michalowski, 2006; Lynch, Nalla & Miller, 1989; Lynch, Stretesky & Hammond, 2000), the criminal justice system (Calavita, Tillman, & Pontell, …


Theoretical And Experimental Investigations To Improve The Performance Of Surface Acoustic Wave (Saw) Biosensors, Mandek Richardson Jan 2014

Theoretical And Experimental Investigations To Improve The Performance Of Surface Acoustic Wave (Saw) Biosensors, Mandek Richardson

USF Tampa Graduate Theses and Dissertations

The objective of this dissertation is to improve the performance of surface acoustic wave (SAW) biosensors for use in point-of-care-testing (POCT) applications. SAW biosensors have the ability to perform fast, accurate detection of an analyte in real time without the use of labels. However, the technology suffers from the inability to differentiate between specific and non-specific binding. Due to this limitation, direct testing of bodily fluids using SAW sensors to accurately determine an analyte's concentration is difficult. In addition, these sensors are challenged by the need to detect small concentrations of a biomarker that are typically required to give a …

Using Habit Reversal To Decrease Filled Pauses And Nervous Habits In Public Speaking, Carolyn Joanne Mancuso

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Public speaking is a challenge faced by people from all walks of life. Research in the area of public speaking has focused on examining techniques to reduce public speaking anxiety. Very little research, however, has focused on the acquisition of public speaking skills. While presenting speeches, many people engage in nervous habits that have the potential to decrease the effectiveness of the speech and their credibility as a speaker. This study evaluated the effectiveness of simplified habit reversal in reducing three of these nervous habits: filled pauses, tongue clicking, and inappropriate use of the word like. Following baseline, participants …


Evolution And Functional Morphology Of The Cephalic Lobes In Batoids, Samantha Lynn Mulvany Dec 2013

Evolution And Functional Morphology Of The Cephalic Lobes In Batoids, Samantha Lynn Mulvany

USF Tampa Graduate Theses and Dissertations

Cephalic lobes are unique structures derived from the anterior pectoral fins, found in select myliobatid stingrays. Many benthic batoids utilize undulatory locomotion and use their pectoral fins for both locomotion and prey capture. Pelagic myliobatids that possess cephalic lobes utilize oscillatory locomotion, using their pectoral fins to locomote and their cephalic lobes for prey capture. Despite differences in habitat usage and locomotor modes, these batoids feed on very similar benthic organisms. The purpose of this study was to 1.) compare the morphology of the cephalic lobes and anterior pectoral fins in lobed and lobeless species, looking at skeletal elements, musculature …


Gay, Straight, Or Slightly Bent? The Interaction Of Leader Sexual Orientation And Gender On Leadership Evaluations, Fred George Macoukji Dec 2013

Gay, Straight, Or Slightly Bent? The Interaction Of Leader Sexual Orientation And Gender On Leadership Evaluations, Fred George Macoukji

USF Tampa Graduate Theses and Dissertations

Abstract

Existing research has shown that gender stereotypes regarding characteristics of men and women influence others' perceptions of their fit with organizational roles, including leadership roles (cf. Eagly & Karau, 2002). However, little research has examined stereotypes regarding other demographic characteristics (e.g., race, sexual orientation) and how they may interact with gender stereotypes to influence leadership evaluations. The current study examined whether leader gender and sexual orientation interact to influence subordinates' evaluations of leader effectiveness, likability, and boss desirability using an experimental design. In addition to examining whether leader gender and sexual orientation interacted to predict leader evaluations, the present …


Contrast Adaptation In The Lateral Eye Of Limulus Polyphemus, Tchoudomira Valtcheva Nov 2013

Contrast Adaptation In The Lateral Eye Of Limulus Polyphemus, Tchoudomira Valtcheva

USF Tampa Graduate Theses and Dissertations

Luminance and contrast adaptation are neuronal mechanisms that the retina applies for continuous adjustment to light sensitivity though a collection of cellular and synaptic mechanisms distributed across the retinal network, thus accommodating the wide input range of the visual system within the constricted output range of retinal ganglion cells. Luminance mean adaptation has been demonstrated in the output neurons of the invertebrate eye (eccentric cells), and the aim of the study was to investigate whether the homology in visual processing extends to luminance variance (contrast) adaptation as well. The spike trains of individual eccentric cells were recorded from live horseshoe …

The Relationship Between Rating Scales Used To Evaluate Tasks From Task Inventories For Licensure And Certification Examinations, Adrienne W. Cadle

USF Tampa Graduate Theses and Dissertations

The first step in developing or updating a licensure or certification examination is to conduct a job or task analysis. Following completion of the job analysis, a survey validation study is performed to validate the results of the job analysis and to obtain task ratings so that an examination blueprint may be created. Psychometricians and job analysts have spent years arguing over the choice of scales that should be used to evaluate job tasks, as well as how those scales should be combined to create an examination blueprint. The purpose of this study was to determine the relationship between individual …


A Distributed Local-Leg Feedback Algorithm For Robust Walking On Uneven Terrain, Mayur Ramakant Palankar Jan 2013

A Distributed Local-Leg Feedback Algorithm For Robust Walking On Uneven Terrain, Mayur Ramakant Palankar

USF Tampa Graduate Theses and Dissertations

Legged animals can traverse significantly more of the Earth's land mass than man-made wheeled and tracked vehicles~\cite{Anonymous67}. Their impressive mobility is largely due to multiple dexterous legs and the robust algorithms that coordinate and control them. A legged animal such as a squirrel can exhibit multiple locomotion modes such as walking, running and jumping and also multiple gaits or leg phase timings within each mode. A robot that could mimic this level of robust locomotion would be highly useful for planetary exploration, military reconnaissance, and time-critical search and rescue in cluttered or collapsed buildings.

A number of biological studies on …

Automatic Macro- And Micro-Facial Expression Spotting And Applications, Matthew Adam Shreve Jan 2013

Automatic Macro- And Micro-Facial Expression Spotting And Applications, Matthew Adam Shreve

USF Tampa Graduate Theses and Dissertations

Automatically determining the temporal characteristics of facial expressions has extensive application domains such as human-machine interfaces for emotion recognition, face identification, as well as medical analysis. However, many papers in the literature have not addressed the step of determining when such expressions occur. This dissertation is focused on the problem of automatically segmenting macro- and micro-expressions frames (or retrieving the expression intervals) in video sequences, without the need for training a model on a specific subset of such expressions. The proposed method exploits the non-rigid facial motion that occurs during facial expressions by modeling the strain observed during the elastic …

Moreover, a passive travel survey collection is preferred to an active travel survey method by the …


Comparison Of Acquisition Rates And Child Preference For Varying Amounts Of Teacher Directedness When Teaching Intraverbals, Victoria Lynn Smith Jan 2013

Comparison Of Acquisition Rates And Child Preference For Varying Amounts Of Teacher Directedness When Teaching Intraverbals, Victoria Lynn Smith

USF Tampa Graduate Theses and Dissertations

The intraverbal is argued to be the most socially significant verbal operant and yet it is the least studied. Heal and Hanley (2011) suggest that different teaching strategies will lead to different rates of acquisition and child-preference with the tacting operant. This study continued this research into the realm of intraverbals, with focus on whether the embedded teaching strategy could be punishing on play or engaging in learning opportunities. The teaching strategies of discovery teaching, embedded prompting, and direct teaching were compared to see which strategy correlated with higher rates of acquisition and higher child preference. The study utilized a …


Assessing The Relationship Between Hotspots Of Lead And Hotspots Of Crime, Kimberly L. Barrett Jan 2013

Assessing The Relationship Between Hotspots Of Lead And Hotspots Of Crime, Kimberly L. Barrett

USF Tampa Graduate Theses and Dissertations

Numerous medical and environmental toxicology studies have established a link between lead (Pb) exposure, crime, and delinquency. In human environments, lead pollution- like crime- is unequally distributed, creating lead hot spots. In spite of this, studies of crime hotspots have routinely focused on traditional sociological predictors of crime, leaving environmental predictors of crime like lead and other neurotoxins relatively unaddressed. This study attends to this gap in the literature by asking a very straightforward research question: Is there a relationship between hotspots of lead and hotspots of crime? Furthermore, what is the nature and extent of this relationship? Lastly, is …


Evaluating The Effectiveness Of A Tablet Application To Increase Eye Contact In Children Diagnosed With Autism, Tricia Jeffries Jan 2013

Evaluating The Effectiveness Of A Tablet Application To Increase Eye Contact In Children Diagnosed With Autism, Tricia Jeffries

USF Tampa Graduate Theses and Dissertations

Studies have shown that increasing eye contact can be accomplished by using reinforcement, prompting, shaping, functional movement training, punishment, and self-monitoring. However, there is a lack of research that evaluates the use of technology as a way to increase eye contact. This study tested the effectiveness of a tablet application at increasing eye contact in children diagnosed with autism. The application requires the child to look at a picture of a person's face and identify the number displayed in the person's eyes in order to receive reinforcement. Data was collected immediately after training, one hour after training, and in the …

A Biocompatible Sic Rf Antenna For In-Vivo Sensing Applications, Shamima Afroz Jan 2013

A Biocompatible Sic Rf Antenna For In-Vivo Sensing Applications, Shamima Afroz

USF Tampa Graduate Theses and Dissertations

A continuous glucose sensor employing radio frequency (RF) signals is presented using the biocompatible material Silicon Carbide (SiC). Unlike biosensors that require direct contact with interstitial fluids to trigger chemical reactions to operate, this biocompatible SiC sensor does not require a direct interface. The sensing mechanism for this SiC sensor is based upon a shift in resonant frequency, as a function of change in glucose levels, which electrically manifests itself as a change in blood permittivity and

conductivity. For in vivo applications the antenna sensor needs to operate inside the body environment, and it has been found that the best …


Supply Chain Optimization Of Blood Products, Serkan Gunpinar Jan 2013

Supply Chain Optimization Of Blood Products, Serkan Gunpinar

USF Tampa Graduate Theses and Dissertations

Major challenges in the management of blood supply chain are related to the shortage and wastage of the blood products. Given the perishability characteristics of blood which can be stored up to a limited number of days, if hospitals and blood centers keep an excessive number of blood units on inventory, wastages may occur. On the other hand, if sufficient number of blood units are not stored on inventory, shortages of this resource may cause the cancellations of important activities and increase the fatality rates at hospitals. Three mathematical models have been developed with the goal to improve the efficiency …

Embodying Social Practice: Dynamically Co-Constituting Social Agency, Brian W. Dunst Jan 2013

Embodying Social Practice: Dynamically Co-Constituting Social Agency, Brian W. Dunst

USF Tampa Graduate Theses and Dissertations

Theories of cognition and theories of social practices and institutions have often each separately acknowledged the relevance of the other; but seldom have there been consistent and sustained attempts to synthesize these two areas within one explanatory framework. This is precisely what my dissertation aims to remedy. I propose that certain recent developments and themes in philosophy of mind and cognitive science, when understood in the right way, can explain the emergence and dynamics of social practices and institutions. Likewise, the view I construct explains how social practices and institutions shape the character of cognition of their constituent agents. Moreover, …

This research explores the lived experiences of new mothers who receive services from a community non-profit lactation support program which is aimed at providing in-home postpartum breastfeeding support to low-income/at-risk mothers. Evaluation of program services and analysis of women's narratives will provide insight into improvement of lactation services for all …


Proteolytic Processing Of The Amyloid Precursor Protein During Apoptosis And Cell Cycle: Implications For Alzheimer's Disease, Tina N. Fiorelli Jan 2013

Proteolytic Processing Of The Amyloid Precursor Protein During Apoptosis And Cell Cycle: Implications For Alzheimer's Disease, Tina N. Fiorelli

USF Tampa Graduate Theses and Dissertations

Alzheimer's disease is characterized by the presence of amyloid plaques, made up primarily of Aϐ peptides, and neurofibrillary tangles, containing hyperphosphorylated tau. Aϐ is generated by sequential proteolysis of the amyloid precursor protein (APP) by beta and gamma secretases. The leading hypothesis of Alzheimer's disease pathogenesis is the amyloid cascade hypothesis, which suggests that amyloid is central to the disease process. However, tau pathology correlates more closely with cognitive dysfunction and follows a predictable anatomical course through the brain. We hypothesize that if Aϐ is upstream of tau pathology and tau pathology follows this predictable course through the brain, Aϐ …

The Effects Of Scaling On Bite Force And Suction Index In The Eastern Hellbender (Cryptobranchus Alleganiensis), Nicholas Patrick Larghi Jan 2013

The Effects Of Scaling On Bite Force And Suction Index In The Eastern Hellbender (Cryptobranchus Alleganiensis), Nicholas Patrick Larghi

USF Tampa Graduate Theses and Dissertations

The hellbender (Cryptobranchus alleganiensis) is a salamander that grows over a large range of body sizes (2-74 cm total length) making it an ideal organism for examining the effects of body size on morphology and performance. The goal of this study is to investigate the morphology changes over ontogeny and change in

feeding ability. Cryptobranchus feeds on small aquatic insects as juveniles and shifts to crayfish as they get larger. Morphology can be expected to change as an organism grows larger, and because morphology and performance are closely linked, this morphological change can result in a change in …
