Contributions Of Appetitive And Aversive Motivational Systems To Decision-Making, Heather E. Soder Nov 2017

Contributions Of Appetitive And Aversive Motivational Systems To Decision-Making, Heather E. Soder

USF Tampa Graduate Theses and Dissertations

Optimal decision-making entails outcome evaluation, comparing received costs and benefits with predicted costs and benefits. The anterior cingulate cortex (ACC), a brain area with major connections to the appetitive and aversive motivation systems, may provide the neural substrate of this evaluation process. One way to measure the relative contribution of these systems on decision-making is to measure individual differences in risk-taking behaviors. For individuals who make risky choices, this evaluation step may be biased: some show a preference for immediate, short-term rewards (increased appetitive system), while devaluing the long-term consequences of their choices (decreased aversive system). However, most studies supporting …

Neural And Behavioral Mechanisms Of Clear Speech, Jenna Silver Luque Nov 2017

Neural And Behavioral Mechanisms Of Clear Speech, Jenna Silver Luque

USF Tampa Graduate Theses and Dissertations

Clear speech is a speaking style that has been shown to improve intelligibility in adverse listening conditions, for various listener and talker populations. Clear-speech phonetic enhancements include a slowed speech rate, expanded vowel space, and expanded pitch range. Although clear-speech phonetic enhancements have been demonstrated across a variety of talkers, only a subset of these changes may be required for listeners to benefit perceptually from clear speech. Furthermore, while current literature has provided some understanding of the phonetic enhancements that are typical of clear speech and the improvements in intelligibility resulting from its use, less is understood regarding how listeners …

Traumatic Brain Injury In Adolescence: The Relationship Between High School Exiting And Future Productivity, Jeffrey S. Garofano Jul 2017

Traumatic Brain Injury In Adolescence: The Relationship Between High School Exiting And Future Productivity, Jeffrey S. Garofano

USF Tampa Graduate Theses and Dissertations

Traumatic brain injury (TBI) is the leading cause of death and disability among children and adolescents. Brain injury survivors are often left with persistent impairments that have the potential to impede daily functioning, delay or prevent the attainment of developmental milestones, and subsequently limit future productivity in adulthood. A shared goal of both neurorehabilitation and the educational system is to prepare youth for a productive adulthood with both systems of care having substantial, yet independent, literature bases regarding factors associated with productivity (e.g., engagement in employment or post-secondary education). It is currently assumed that because type of high school exiting …

Identifying Nodes Of Transmission In Disease Diffusion Through Social Media, David Sebastian Lamb Jul 2017

Identifying Nodes Of Transmission In Disease Diffusion Through Social Media, David Sebastian Lamb

USF Tampa Graduate Theses and Dissertations

The spread of infectious diseases can be described in terms of three interrelated components: interaction, movement, and scale. Transmission between individuals requires some form of interaction, which is dependent on the pathogen, to occur. Diseases spread through the movement of their hosts; they spread across many spatial scales from local neighborhoods to countries, or temporal scales from days to years, or periodic intervals. Prior research into the spread of disease have examined diffusion processes retrospectively at regional or country levels, or developed differential equation or simulation models of the dynamics of disease transmission. While some of the more recent models …

Can We Talk?: Synergistic Effects Of Cognitive And Behavioral Frameworks To Address Substance Use And Abuse, Lauren Jaye Adams Jun 2017

Can We Talk?: Synergistic Effects Of Cognitive And Behavioral Frameworks To Address Substance Use And Abuse, Lauren Jaye Adams

USF Tampa Graduate Theses and Dissertations

Behavioral economic accounts of substance use have provided a novel framework to examine constraints that affect behaviorally driven outcomes. Several behavioral studies support the application of such frameworks to examine impulsive decision-making processes as well as how subjective reward influences substance use. Based on stimulus-response models, behavioral economic research often applies mathematical formulas to draw conclusions about behavioral outcomes. These mathematical formulas, while useful, largely ignore decades of cognitive psychology research that have examined state-based influences (e.g., mood, environment, motivational processes, etc.) on behavioral sequelae. To address this issue, the present study merged a cognitive framework into two behavioral economic …

Many Hands Make Light Work: Crowdsourced Ratings Of Medical Student Osce Performance, Mark Grichanik Apr 2017

Many Hands Make Light Work: Crowdsourced Ratings Of Medical Student Osce Performance, Mark Grichanik

USF Tampa Graduate Theses and Dissertations

Clinical skills are often measured using objective structured clinical examinations (OSCEs) in healthcare professions education programs. As with assessment centers, it is challenging to provide learners with effective feedback due to burdensome human capital demands. The aim of this dissertation was to evaluate the viability of using a crowdsourced system to gather OSCE ratings and feedback. Aggregating evaluations of student performance from a crowd of patient proxies has the potential to mitigate biases associated with single-rater evaluations, allow the patient a voice as the consumer of physician behavior, improve reliability, reduce costs, improve feedback latency, and help learners develop a …

Poverty In The Land Of Plenty? Deconstructing Role Of Community-Based Organizations In A Small Community, John Kevin Trainor Apr 2017

Poverty In The Land Of Plenty? Deconstructing Role Of Community-Based Organizations In A Small Community, John Kevin Trainor

USF Tampa Graduate Theses and Dissertations

Using the lens of a community-based childhood obesity intervention, it is possible to examine the role of non-profit organizations in community development and to deconstruct the “community” in community-based research and identify the many competing interests within a community. This contextual understanding includes how the community is formed, how a community’s agenda is set, and who will complete the tasks outlined in that agenda. In applied anthropological settings and public health interventions that are community-based, it is essential to understand the context of community and which community (or communities) the researcher is working with to ensure that the data you …

(Not) Everything Is Good And Easy: Language-Related Healthcare Experiences Of Two Groups Of Low-Income Latina Mothers, Aria Anna Walsh-Felz Mar 2017

(Not) Everything Is Good And Easy: Language-Related Healthcare Experiences Of Two Groups Of Low-Income Latina Mothers, Aria Anna Walsh-Felz

USF Tampa Graduate Theses and Dissertations

This cross-sectional, comparative, qualitative study explored language-related issues experienced by low-income Spanish-speaking mothers navigating pediatric care for their children in Hillsborough County, Florida. Hospitals, pediatric clinics, specialists, and dental care have differing degrees of linguistic accessibility and accommodations for limited English proficient families. Two groups of mothers were interviewed: bilingual (n=9) and Spanish-speaking limited-English proficient (SSLEP) mothers (n=21). These groups perceived the effect of language on navigating pediatric healthcare differently, creating tension in perceptions and experience between them. Such tensions included SSLEP mothers expressing satisfaction with pediatric care simultaneously with shortcomings in communication. SSLEP mothers said that everything was easy, …

Reducing Caregiver Burden: Fostering Healthy Aging And Social Support, Maria A. Rodriguez Mar 2017

Reducing Caregiver Burden: Fostering Healthy Aging And Social Support, Maria A. Rodriguez

USF Tampa Graduate Theses and Dissertations

Over 43.5 million Americans provide informal care to a fast-growing elderly population in the United States. Informal care allows care-recipients to remain functional members of society. However, research suggests that the demands of informal care can negatively impact the health of caregivers. For example, caregiver burden increases the risk for poor health in caregivers compared to non-caregivers. Caregiving research is on the rise, but the dynamics of informal care in active retirement communities remains widely unexplored. To provide adequate services to lessen caregiver burden and improve the Quality of Life (QoL) of informal caregivers, the various settings in which informal …

Testing The Medical Arms Race Hypothesis: A Spatial Approach, Robyn M. Kibler Mar 2017

Testing The Medical Arms Race Hypothesis: A Spatial Approach, Robyn M. Kibler

USF Tampa Graduate Theses and Dissertations

The surgical robot experienced rapid uptake throughout hospitals in the US despite lack of clinical evidence that it is superior to existing methods and undeterred by its high cost. This type of technology may be a “weapon” in the medical arms race hypothesis which asserts that competition among hospitals may be welfare reducing wherein it encourages resource use that is not commensurate with beneficial health outcomes. This paper is a case-study of the diffusion of the surgical robot among hospitals in Florida. We address the medical arms race hypothesis directly by investigating whether a hospital’s decision to adopt a robot …
