Using Awareness Training To Decrease Nervous Habits In Public Speaking, Claire Spieler

USF Tampa Graduate Theses and Dissertations

Research on components of habit reversal suggests that awareness training alone may be an effective and efficient intervention for reducing nervous habits. This study evaluated the effectiveness of awareness training for the reduction of three nervous habits that manifest in public speaking: filled pauses, tongue clicks, and inappropriate use of the word "like." Four university students delivered short speeches during baseline and assessment sessions. Awareness training consisted of response description and response detection. Awareness training resulted in meaningful reductions in target behaviors for all participants. Booster awareness training sessions were necessary for all participants to achieve further reductions in target …

Using Gamification To Increase Adherence To Daily Living Routines, Lisa S. Kadison

USF Tampa Graduate Theses and Dissertations

Gamification, the use of game elements in non-game contexts, is an increasingly popular way to incentivize self-management procedures. Despite the growing popularity of such programs, little objective research has been done in the area. This study evaluated the use of a web-based gamification program called HabitRPG through a multiple-baseline across participants design. HabitRPG is designed to increase the productivity of its users. Baseline procedures included parental scoring of task completion. Intervention consisted of training on using HabitRPG. Target behaviors were scored with data sheets provided to parents of the participants. The intervention increased the percentage of compliance for all participants.

Myths And Miracles In Mexico City: Treatment Seeking, Language Socialization, And Identity Among Deaf Youth And Their Families, Anne Elaine Pfister

USF Tampa Graduate Theses and Dissertations

This dissertation research investigates the experience of deafness among deaf youth, adults, and their families in Mexico City, Mexico. Deaf children cannot fully access the spoken languages of their hearing families and mainstream society. Hence, participating families embarked upon extensive treatment-seeking pilgrimages, encountering myths about deaf lifeways and the promise of miracle cures that formed Mexico City's cultural system for coping with childhood deafness. This ethnography uncovers persistent misconceptions in medical and mainstream discourse, including strong recommendations against exposure to sign language, which directly impacted participants' access to relevant communities of practice, the social networks that proved most significant to …

Auteurs At An Urban Crossroads: A Certain Tendency In New York Cinema, Rene Thomas Rodriguez

USF Tampa Graduate Theses and Dissertations

Perhaps more than any other major American city in the 1970s, New York represented the decline of an urban existence. Job loss from factors related to deindustrialization and intense crime occupied local and national news, reflecting the increasing anxiety of America's future. New York City was positioned at the center of this frightening chaos. Films made during this period, known by film scholars and journalists as the "New Hollywood" captured the collective temperament of the people and the physical space they inhabit during its disintegration. The depiction of New York during the 1970s has been widely discussed in the writing …

Ironic Masculinity And Femininity: Do Contextual Factors Reverse Attributions Based On Gender Stereotyped Behaviors?, Kenneth S. Michniewicz

USF Tampa Graduate Theses and Dissertations

Emerging research highlights the social penalties for men and women who commit cross-gendered behaviors. Here, I examine how and when two contextual mechanisms (competence and credentials) alter people's perceptions of cross-gendered behavior and render actors as less gender-atypical and more gender-typical. In Study 1, I tested the hypothesis that incompetence in cross-gendered behaviors would communicate same-gendered qualities by contrast. In Study 2, I tested the hypothesis that an actor who commits a cross-gendered behavior will receive less gender-inconsistent evaluations if they first demonstrate gender-typical traits. Moreover, Study 2 examines whether or not these credentialed actors change the perception of the …

The Detection And Quantitative Analysis Of Endocannabinoids And Endogenous Fatty Acid Amides In Apis Mellifera And Tribolium Castaneum, Perry Robert Mitchell Jr.

USF Tampa Graduate Theses and Dissertations

Endocannabinoids, and the fatty acid amides from which they are a member, have garnered greater scientific interest in the last two decades due to the cannabimimetic properties of these endogenous molecules. The most well-known of these is Anandamide, which has thus far been discovered in several species of animal ranging from C. elegans, fruit flies, to bovine and humans. Because of the importance and increasing impact of these compounds a brief overview is first presented herein, with a major focus on the N-acyldopamines due to the direct impact they potentially pose to human physiology.

Secondly, the detection and …

Solids Accumulation Rates Of Latrines At Rural Schools In Nimba County, Liberia, Caraline M. Murphy

USF Tampa Graduate Theses and Dissertations

Access to appropriate sanitation facilities as well as access to clean drinking water are considered fundamental human rights (Carr, 2001; Bjorklund & Sjodin, 2010), yet roughly 2.5 billion people on the planet lack access to an improved form of sanitation (WHO/UNICEF, 2014). Additionally, many entities responsible for emergency excreta management and sanitation management design guidelines, specifically solids accumulation rates in latrine pits, use rates that are 30-60 years old and may be established from dated knowledge on diet and lifestyle trends (Franceys et al., 1992; Harvey et al., 2002; Harvey, 2007). Using solids accumulation rates that are dated as well …

The Archaeology Of The Mckinnie Site (8ja1869), Apalachicola River Valley, Northwest Florida: Four Thousand Years In The Backswamp, Eric D. Prendergast

USF Tampa Graduate Theses and Dissertations

This research describes a large, newly-recorded archaeological site in the Upper Apalachicola River valley, northwest Florida, and a private collection of artifacts from it, as well as test excavations, three-dimensional modeling, clay/pottery sourcing through chemical analysis, and direct radiocarbon dating of ceramics to relate the site with regional archaeological chronologies and settlement patterns. A University of South Florida (USF) 2013 field school conducted excavations at the multicomponent midden on the western floodplain of the Apalachicola River called the McKinnie site (8JA1869). Students collaborated with a local collector and family members to learn about the site's history. Data from the collection …

Does Emotional Processing Mediate The Link Between Disordered Sleep And Depression?, Kimberly O'Leary

USF Tampa Graduate Theses and Dissertations

Disordered sleep is strongly linked to depression, but reasons for this are not well understood. One possibility is that this link is partially explained by deficits in the emotional processing system. This model is substantiated based on the strong link between sleep and emotions, as well as ties between affect and depression. Therefore, this study tested whether various emotional and non-emotional deficits mediated the link between poor sleep quality and depression. Two hundred undergraduate students were recruited via an online university system. Participants completed self-report scales of depression, sleep quality, emotion recognition, and affective response to pre-tested pleasant or unpleasant …

Viability Of Bismuth As A Green Substitute For Lead In Jacketed .357 Magnum Revolver Bullets, Joel A. Jenkins

USF Tampa Graduate Theses and Dissertations

In seeking to develop environmentally friendly lead-free non-toxic bullets, the research ballistically evaluated the performance of copper-jacketed handgun bullets containing a pure bismuth core. The lead was first removed from 140 grain Hornady^TM XTP® bullets of 38 caliber (.357 diameter) by melting. The empty jackets were then refilled with pure bismuth, including the forming of a correctly sized hollow-point cavity. Due to the lower density of bismuth as compared to lead, the bismuth-cored bullets consistently weighed 125 gains. Conveniently this allowed direct comparison to commercially available 125 grain Hornady^TM XTP® lead-cored bullets of 38 caliber. Both bismuth-cored and …

"Tell Me, Where Am I From?": A Study Of The Performance Of Geek Identity At Comic Book Conventions, Eric Kahler

USF Tampa Graduate Theses and Dissertations

The performance of identity is an often studied subject matter. One identity, Geek, and the larger subculture to which it is attached (Geek culture) has become a growing field of study in since the turn of the millennium, mirroring the growth of the subculture itself. The question then is how do Geek's perform this identity and create an idea of what a Geek is? If there is a place to examine this performance then it is the growing event of comic book conventions. At these events thousands of individuals gather to celebrate, interact with, purchase and play with the commodities …

This study asked a focus group about their uses and gratifications from textisms. The focus group delved into their appreciations as both users and receivers. Participants reflected on their personal experience and preferences with textisms for their personal communications as well as their opinion for various types of businesses using them in their larger message design efforts.

The participants were comprised of …

Let's Go To The Carnival: Hybridization Of Heterotopian Spaces In The Films Of Kevin Smith, Anthony L. Sylvester

USF Tampa Graduate Theses and Dissertations

This paper argues against the charges of puerility in the films of Kevin Smith. I analyze Mallrats (1995), Clerks II (2006) and Zack and Miri Make a Porno (2008). To illustrate my contention, I offer close readings of the director's films, particularly the protagonists' bodily/linguistic performances. My efforts will vindicate my assertion that through these specialized performances, through the forceful assertion of their marginal identities, the films' protagonists encroach upon, and finally appropriate, historically dominant spaces. As a result, the spaces they appropriate acquire a new, characteristic hybridity. Michel Foucault's concept of heterotopia provides a framework for delineating the dominant …

The Association Of Cognitive Endophenotypes And Risky Single Nucleotide Polymorphisms Of Alzheimer's Disease Within The Alzheimer's Disease Neuroimaging Initiative (Adni) Database, Kyle Joseph Jennette

USF Tampa Graduate Theses and Dissertations

Objective: The purpose of this study was to assess the influence of three single nucleotide polymorphisms (SNP) previously associated with Alzheimer's disease on specific domains of cognition, when controlling for Apolipoprotein E gene (APOE), in a sample of individuals with Alzheimer's disease. Methods: The data were drawn from the Alzheimer's Disease Neuroimaging Initiative database, a comprehensive, longitudinal database of controls, persons with mild cognitive impairment, and persons with mild Alzheimer's disease. Each subject has a full neuropsychological assessment, neuroimaging, genetic sequencing, and physical evaluation. For the purposes of this study, individuals were selected based on the presence of the three …

A Functional Chlorophyll Biosynthesis Pathway Identified In The Kleptoplastic Sea Slug, Elysia Chlorotica, Julie A. Schwartz

USF Tampa Graduate Theses and Dissertations

The sacoglossan sea slug, Elysia chlorotica, feeds upon and sequesters plastids from the heterokont alga, Vaucheria litorea, and maintains the metabolically active organelles for up to nine months under starvation conditions while utilizing the photosynthate to survive and reproduce. The photosynthetic pigment, chlorophyll a (Chla), is found in all oxygenic photosynthetic organisms and is responsible for capturing photons of light and converting them into chemical energy. Chlorophyll and its associated proteins involved in the light capturing process are subject to photo oxidative damage and must be continually replaced for ongoing photosynthesis to continue; however, genes encoding these proteins are present …

Utilizing Systems Level Approaches To Identify Key Mechanisms Of Drug Resistance In Braf Mutated Melanoma, Kim H.T. Paraiso

USF Tampa Graduate Theses and Dissertations

In the last four years, seven new drugs have been FDA approved for the treatment of late stage melanoma, for the field of melanoma, this marks an incredibly exciting. Three of these new therapies, vemurafenib, dabrafenib and trametinib are small molecule kinase inhibitors that target the MAPK pathway and as such have been approved for the treatment of BRAFV600 mutant melanomas. Yet despite recent advances, mechanisms of intrinsic and acquired BRAF inhibitor resistance continue to undermine uniform and long-lasting therapeutic responses. Several studies have shown that the reactivation of MAPK signaling is a critical event leading to BRAF inhibitor resistance. …

Status Of A Translocated Florida Sand Skink Population After Six Years: Establishing And Evaluating Criteria For Success, Adam Ryan Emerick

USF Tampa Graduate Theses and Dissertations

The translocation of organisms is becoming a frequently used tool in conservation biology. There are, however, a disproportionate number of unsuccessful attempts translocating populations of herpetofauna. Logistical and temporal limits of monitoring, combined with ambiguous metrics concerning "success," have led to few advances regarding reptile translocations. Successfully established and persistent populations are those in which both the founding population and subsequent generations show consistent or positive levels of survival and reproduction. A small population of the threatened Florida Sand Skink (Plestiodon reynoldsi) was translocated in 2007. Data collected from 2007 to 2009 confirmed survival and reproduction among the founding individuals, …

Cogs In A Cosmic Machine: A Defense Of Free Will Skepticism And Its Ethical Implications, Sacha Greer

USF Tampa Graduate Theses and Dissertations

Free will skepticism denies that humans possess the type of freedom required for moral responsibility (FMR). While not the most popular position in scientific, philosophical, or mainstream communities, I contend that this lack of acceptance is due not to flaws inherent in the position, but to misconceptions concerning its ethical and practical implications. In my dissertation, I endorse free will skepticism, beginning with a refutation of contrary positions, followed by a response to objections, and ending with a defense of social reforms necessitated by the denial of free will. Ultimately, I support Derk Pereboom's optimism that a global acceptance of …

Identification And Characterization Of N-Acyltransferase Enzymes That Are Involved In The Biosynthesis Of Fatty Acid Amides, Daniel Robert Dempsey

USF Tampa Graduate Theses and Dissertations

Fatty acid amides are an emerging family of bioactive lipids that consists of N-acylethanolamines, N-acylarylalkylamides, N-acylglycines, N-acyl amino acids, N-monoacylpolyamides, and primary fatty acid amides. Short chain fatty acid amides are products of inactivated biogenic amines such as dopamine, histamine, octopamine, and serotonin, whereas long chain fatty acid amides have been implicated in a number of physiological process such as the perception and inhibition of chronic pain through binding to their specific receptors. The most famous; therefore, the most studied long chain fatty acid amide is anandamide or also known as N-arachidonylethanolamine. The biosynthesis …

Reducing The Control Burden Of Legged Robotic Locomotion Through Biomimetic Consonance In Mechanical Design And Control, Caitrin Elizabeth Eaton

USF Tampa Graduate Theses and Dissertations

Terrestrial robots must be capable of negotiating rough terrain if they are to become autonomous outside of the lab. Although the control mechanism offered by wheels is attractive in its simplicity, any wheeled system is confined to relatively flat terrain. Wheels will also only ever be useful for rolling, while limbs observed in nature are highly multimodal. The robust locomotive utility of legs is evidenced by the many animals that walk, run, jump, swim, and climb in a world full of challenging terrain.

On the other hand, legs with multiple degrees of freedom (DoF) require much more complex control and …

Keeping Up With The Grandkids: Using Tagteach To Train Baton Twirling Skills In Older Adults, Sarah Elizabeth Hester

USF Tampa Graduate Theses and Dissertations

Exercise has many physical, cognitive, and social benefits, but the majority of older adults do not meet the recommended level of physical activity (Centers for Disease Control and Prevention, 2014). TAGteach, which combines elements of both behavioral coaching and acoustical feedback, has been demonstrated as an effective way to teach athletic skills (Fogel, Weil, & Burris, 2010; Quinn, Miltenberger, & Fogel, 2015; Stokes, Luiselli, Reed, & Fleming 2010). However, none of the current research on teaching athletic skills targeted an older population. This study evaluated TAGteach in a multiple baseline across behaviors design as a method of teaching 4 basic …

Mediation And Moderation Analysis Of Nutrition, Inflammatory Biomarkers, And Cognition In Older Adults, Elizabeth Handing

USF Tampa Graduate Theses and Dissertations

Nutrition can be viewed as a modifiable factor related to maintaining and preserving health in older adults. Previous studies have found that nutritional factors can influence cognitive abilities, however few studies have examined macronutrients and micronutrients as they relate to cognitive functioning. Research has yet to examine the mechanisms related to nutrition, cognition and aging in an older adult population from a holistic and interactive perspective.

This dissertation examined three research questions to better understand the relationship between age, nutrition, cognition, and inflammatory biomarkers. First, is nutrition related to cognition beyond demographic factors? Do individual nutrients serve as mediators? Second, …

Using Auditory Feedback To Improve Dance Movements Of Children With Disabilities, Takema J. James

USF Tampa Graduate Theses and Dissertations

Research incorporating behavior analysis to improve sports performance has shown that various feedback types (e.g., video feedback, public posting) can increase skills. Recently, auditory feedback has been shown to be effective. The purpose of this study was to evaluate the utility of auditory feedback to improve dance movements of children with disabilities using an ABAB design embedded in a multiple baseline across participants design. The target behaviors were fundamental dance skills, individualized to each student, and scored using a task analysis to calculate the percentage of correct steps. The results showed that auditory feedback was valuable in increasing the specific …

Using Video Feedback To Increase Job Interview Skills For Young Adults With Developmental Disabilities, Jessica Lynn Moore

USF Tampa Graduate Theses and Dissertations

Individuals diagnosed with developmental disabilities often lack the skills needed to gain meaningful employment in the community. One crucial skill is interviewing as this is the first and often the only pre-job interaction an individual has with his or her employer. In a short interaction, the person must convey information about specific work history, employability, and a general impression of character. This study evaluated the effectiveness of video feedback in improving job interview behaviors for three young adults with developmental disabilities. The interview related-behaviors were appropriate greeting, responses to interview questions, and appropriate closing statement. The performance across the participants …

A Novel Update To Dynamic Q Algorithm And A Frequency-Fold Analysis For Aloha-Based Rfid Anti-Collision Protocols, Nikita Khanna

USF Tampa Graduate Theses and Dissertations

Radio frequency identification (RFID) systems are increasingly used for a wide range of applications from supply chain management to mobile payment systems. In a typical RFID system, there is a reader/interrogator and multiple tags/transponders, which can communicate with the reader. If more than one tag tries to communicate with the reader at the same time, a collision occurs resulting in failed communications, which becomes a significantly more important challenge as the number of tags in the environment increases. Collision reduction has been studied extensively in the literature with a variety of algorithm designs specifically tailored for low-power RFID systems.

Fear Conditioning And Extinction In Childhood Obsessive-Compulsive Disorder, Joseph F. Mcguire

USF Tampa Graduate Theses and Dissertations

Fear conditioning and extinction are central in the cognitive behavioral model of obsessive-compulsive disorder (OCD), which underlies exposure-based cognitive behavioral therapy (CBT). Youth with OCD may have impairments in conditioning and extinction that carries treatment implications. The present study examined these processes using a differential conditioning paradigm. Forty-one youth (19 OCD, 22 community controls) and their parents completed a battery of clinical interviews, rating scales, and a differential conditioning task. Skin conductance response (SCR) served as the primary dependent measure across all three phases of the conditioning procedure (habituation, acquisition, and extinction). During habituation, no meaningful differences were observed between …

Effects Of A Brief Relaxation Intervention On Stress-Related Eating, Laura Lynn Mayhew-Purcell

USF Tampa Graduate Theses and Dissertations

The experience of stress may contribute to increased food consumption and selection of unhealthy food options. Resource depletion theory suggests stress temporarily depletes resources needed to regulate behavior. Depletions of self-control may result in subsequent failure to regulate eating behaviors, which is particularly salient in restrained eaters. Restraint theory posits people high in dietary restraint require significant effort to control eating. Emotional eating theory further suggests palatable foods may be used to regulate emotional stress reactions. Relaxation exercises to mitigate stress reactions are recommended in eating and weight management programs, but lack quality scientific support. The current study examined the …

Relational Agency, Networked Technology, And The Social Media Aftermath Of The Boston Marathon Bombing, Megan M. Mcintyre

USF Tampa Graduate Theses and Dissertations

Agency is a foundational and ongoing concern for the field of Rhetoric and Composition. Long thought to be a product and possession of human action, rhetorical agency represents the most obvious connection between the educational and theoretical work of the field and the civic project of liberal arts and humanities education. Existing theories of anthropocentric rhetorical agency are insufficient, however, to account for the complex technological work of digitally enmeshed networks of humans and nonhumans. To better account for these complex networks, this project argues for the introduction of new materialist theories of distributed agency into conversations about agency within …

Obsidian Source Selection In The Early Bronze Age Cyclades, Jessica Anne Morgan

USF Tampa Graduate Theses and Dissertations

From excavations of burial complexes of the Early Bronze Age Cyclades (c. 3000-2200 BC) we know that obsidian was just as important and as widely consumed in burial contexts as it was in contemporaneous household contexts; Early Bronze Age Cycladic tomb assemblages are dominated by beautiful obsidian blades produced through a unique knapping technique reserved for burial contexts (Carter 2007; Dickinson 1994). The lack of sourcing studies in the area is an unfortunate pitfall in Aegean archaeology, as understanding patterns of source selection provides us with precious insight into the complex social structures and behaviors that characterized these ancient communities. …

The Triumvirate Of Intersectionality: A Case Study On The Mobilization Of Domésticas In Brazil, Kristen Lei Nash

USF Tampa Graduate Theses and Dissertations

In this thesis, I look at the mobilization of the domestic workers in Brazil as a social movement. In Brazil, the domestic workers have managed to organize continuously for over eight decades using both informal and formal mechanisms to connect workers all over the country in unique ways. By viewing these women and the ways in which they have organized in the framework of a social movement, we can begin to identify their repertoires of contention and how those repertoires have contributed to the successes of the movement. In order to guide this investigation, I ask, how has the doméstica …
