Neurophysiological Activity Related To Speech Production: An Erp Investigation, Adithya Chandregowda

USF Tampa Graduate Theses and Dissertations

The event related potential (ERP) technique is enjoying widespread application in neurophysiological research due to its fine temporal resolution. Of relevance to this study are ERPs related to voluntary movements. The precision with which movement related processes could be recorded using the ERP technique was demonstrated by Gilden, Vaughan and Costa (1966) and Kutas and Donchin (1974, 1977, and 1980) who found that the readiness potential (RP) immediately preceding hand movement was larger over the hemisphere contralateral to the responding hand. Given that left hemisphere controls right hand movements and vice versa, their findings confirmed that the lateralized readiness potential …

Lipoproteins And Health Outcomes: Cognitive And Physical Function In Older Adults, Marianne Chanti-Ketterl

USF Tampa Graduate Theses and Dissertations

Cardiovascular health is a major determinant of quality of life and mortality, especially in older adulthood. With the world’s oldest population increasing at expedited rates, challenges from cardiovascular conditions and its implications are spawning. Although it is well known that dyslipidemia may lead to cardiac events, less is known about the effects on cognitive and physical function in older adults. Epidemiological studies show that optimizing current preventive strategies even at older ages may reduce the incidence of cardiovascular comorbidity (e.g. hypertension, stroke) and increase quality of life. Determining the association between lipoproteins and cognitive and functional performance in older adults …

Cognitive Load Of Registered Nurses During Medication Administration, Sarah Faith Perron

It is important to understand the cognitive load (CL) of Registered Nurses (RNs) working in an electronic health record environment to identify the risk factors of medication errors. The purpose of this study is to investigate the factors that influence the CL of RNs during medication administration who are working in an electronic health record environment. Simulated medication administration scenarios with varying …

Estimating Likelihood Of Having A Brca Gene Mutation Based On Family History Of Cancers And Recommending Optimized Cancer Preventive Actions, Mehrnaz Abdollahian

USF Tampa Graduate Theses and Dissertations

BRCA1 and BRCA2 are gene mutations that drastically increase chances of developing breast and ovarian cancers, up to 20-fold, for women. A genetic blood test is used to detect BRCA mutations. Though these mutations occur in one of every 400 in the general population (excluding Ashkenazi Jewish ethnicity), they are present in most cases of hereditary breast and ovarian cancer patients. Hence, it is common practice for the physicians to require genetic testing for those that fit the rules as recommended by the National Cancer Comprehensive Network. However, data from the Myriad Laboratory, the only provider of the test until …

The Impact Of Lingual Resistance Training In Two Individuals With Amyotrophic Lateral Sclerosis: A Case Series, Raele Donetha Robison

USF Tampa Graduate Theses and Dissertations

Introduction: Amyotrophic Lateral Sclerosis (ALS) is a fatal and progressive disease characterized by the deterioration of motor neurons within the body. This degeneration leads to bulbar dysfunction in the form of an impaired ability to communicate and swallow. Currently, bulbar dysfunction is treated via compensatory methods aimed at maximizing comfort and safety that include environmental adaptations, augmentative and assistive communication and gastrostomy tube placement to replace speech and oral feeding. The role of active intervention is controversial in this patient population and no investigations have examined the potential role lingual exercise might play in ALS bulbar management. The purpose of …

Energy Production And Effluent Quality In Tubular Digesters Treating Livestock Waste In Rural Costa Rica, Maureen Njoki Kinyua

USF Tampa Graduate Theses and Dissertations

Use of tubular anaerobic digesters to treat livestock waste in developing countries has energy, agricultural, health, social and environmental benefits. However, careful use of digester effluent as a soil amendment is required due to the potential presence of protozoan parasites Cryptosporidium parvum and Giardia lamblia. This research investigated the performance of four tubular digesters in the Monteverde region of Costa Rica. High (>75%) volatile solids and BOD5 removal efficiencies were observed, which was attributed to the formation of a biologically active floccular sludge layer. Computational fluid dynamics (CFD) and bioprocess models were developed to evaluate the transport and transformation …

A Comparative Evaluation Of The Learner Centered Grading Debriefing Method In Nursing Education, Marisa J. Belote

USF Tampa Graduate Theses and Dissertations

The nursing discipline lacks a consensus on a best practice method for debriefing students following simulation-based training. A recognized, standardized method does not exist and various methods are utilized within the domain. The similarities between aviation and healthcare are well documented. Training members of both disciplines require standardization and methods of best practice. The aviation industry through the Federal Aviation Administration has found Learner Centered Grading (LCG) to be a successful educational format. The utilization of the LCG Debriefing method in simulation-based training is the standardized debriefing format for a technologically dynamic industry.

The aim of this research was to …

Neuroinflammatory Alterations Via Cd-36 In Traumatic Brain Injury, Diana G. Hernandez-Ontiveros

USF Tampa Graduate Theses and Dissertations

Traumatic brain injury (TBI) has become an increasingly unmet clinical need due to intense military conflicts worldwide. Directly impacted brain cells suffer massive death, with neighboring cells succumbing to progressive neurodegeneration accompanied by inflammatory and other secondary cell death events. Subsequent neurodegenerative events may extend to normal areas beyond the core of injury, thereby exacerbating the central nervous system’s inflammatory response to TBI. Recently CD-36 (cluster of differentiation 36/fatty acid translocase (FAT), a class B scavenger receptor of modified low-density lipoproteins (mLDLs) in macrophages, has been implicated in lipid metabolism, atherosclerosis, oxidative stress, and tissue injury in cerebral ischemia, and …

Anticipatory Coarticulation And Stability Of Speech In Typically Fluent Speakers And People Who Stutter Across The Lifespan: An Ultrasound Study, Alissa Joy Belmont

USF Tampa Graduate Theses and Dissertations

This study uses ultrasound to image onset velar stop consonant articulation in words. By examining tongue body placement, the extent of velar closure variation across vowel contexts provides for the measurement of anticipatory coarticulation while productions within the same vowel context provide measurement of extent of token-to-token variation. Articulate Assistant Advanced 2.0 software was used to semi-automatically generate midsagittal tongue contours at the initial point of maximum velar closure and was used to fit each contour to a curved spline. Patterns of lingual coarticulation and measures of speech motor stability, based on curve-to-curve distance (Zharkova, Hewlett, & Hardcastle, 2011), are …

Exploring The Underlying Mechanisms Of Comorbid Adhd And Eating Disorders, Jennifer Rebecca Bleck

USF Tampa Graduate Theses and Dissertations

Evidence suggests comorbidity of ADHD and eating disorders (EDs) among females. Capitalizing on the comorbidity of ADHD and EDs and subsequent obesity could lead to improved prevention and treatment of all three conditions. However, additional information regarding the comorbidity is necessary to develop such interventions, as little is known about how or why this co-occurrence exists. A comprehensive model of the underlying mechanisms associated with comorbid ADHD and EDs is needed to improve understanding of the development of the comorbidity. Moreover, while there are gender differences within each disorder, literature is limited regarding to the comorbidity among males, leading to …

Validity Testing Of A Preschool Reading Screening Device For Pediatricians, Erika Elaine Blue

USF Tampa Graduate Theses and Dissertations

Despite efforts to improve access to early literacy intervention in the United States, there are still children entering kindergarten that are not adequately prepared for school and are unlikely to catch up to their peers (National Education Association, 2014). Preschool programs are actively involved in screening their students for potential literacy difficulties; however, there are children who do not attend preschool and may not have their literacy development assessed. One solution to this problem is to involve other individuals who routinely see preschool age children. Pediatricians are one such group as children come to them for their wellness visits and …

Sleep, Depressive Symptoms And Cognition In Older Adults And Caregivers Of Persons With Dementia, Glenna Shemida Brewster

USF Tampa Graduate Theses and Dissertations

Caregivers of persons with dementia, who are often older adults, report sleep disturbance, high rates of depressive symptoms and may be at risk for impaired cognition. This dissertation examined sleep, depressive symptoms, and cognition in older adults and caregivers of persons with dementia. The aims of the review of literature were to understand, in community dwelling adults 60 years and older, the relationships among sleep parameters (sleep onset latency, wake after sleep onset, sleep efficiency, total sleep time, and general sleep complaints), and the domains of cognition (Executive Function, Attention, Episodic Memory, Working Memory, Processing Speed), and global cognition. Based …

Latino Immigrant Workers’ Search For Justice After Occupational Injury, Carla Gabriela Castillo

USF Tampa Graduate Theses and Dissertations

Latino immigrants encounter an entanglement of rights and policies after occupational injury or illness. In collaboration with an immigrant worker center, ethnographic research and a survey are used to analyze injured workers’ experiences. The center uses survey results to identify common threads and systematic problems, and to explore potential direct action. Through interviews with workers and medical and legal professionals, I investigate the barriers Latino immigrants face following occupational injury or illness, how their lived experiences relate to the greater medicolegal frameworks that demarcate most formal processes of compensation and treatment, and the experiences of professionals who mediate these structures. …

Effects Of Occupational Stressors On Nurses’ Safety Performance And Well-Being: A Within-Individual Study, Xinxuan Che

USF Tampa Graduate Theses and Dissertations

Occupational stressors have been extensively studied as predictors of safety performance and employee well-being in previous research. However, many newly introduced organizational constructs that have the characteristics of an occupational stressor have rarely been studied as such, especially from a within-person perspective. The current study focused on three occupational stressors in relation to safety performance. Based on previous literature, I proposed that within individuals, compulsory citizenship behavior, illegitimate tasks, and interpersonal conflict at work as occupational stressors would have negative effects on employees well-being and safety performance through negative emotions (anger), job attitudes (job satisfaction and organizational commitment) and role …

Mindfulness Attributes As Predictors Of Treatment Outcomes In Children Who Stutter, Jenna Lee Graepel

USF Tampa Graduate Theses and Dissertations

A recent U.S.-based survey (Boyle et al,. 2011) estimated stuttering prevalence in American children ages 3-17 years at 1.6% or 1 in 63 children. In comparison to the reported 1 in 68 school age children living with Autism Spectrum Disorder (Centers for Disease Control and Prevention, 2010), stuttering affects nearly as many. These estimates suggest that Speech-Language Pathologist (SLPs) should increasingly develop their skill sets for identifying and providing interventions for children who stutter.

The evidence base for school-age fluency intervention, while promising, leaves much room for further development (Nippold, 2011). The majority of current interventions revolve around the traditional …

Theoretically Guided Examination Of Caregiver Strain And Its Relationship With School-Based Mental Health Services Utilization And Parent Engagement In Services, Amy Lynn Green

USF Tampa Graduate Theses and Dissertations

Broadly, the purpose of this study was to address the gaps in the knowledge base of caregiver strain through an examination of this and other theoretically related constructs in a sample of parents of high-risk youth. In the last two decades, a growing body of research has pointed to the significance of strain that can result from this caregiving experience, particularly as it relates to patterns of mental health services utilization. Despite the fact that the majority of children who receive mental health receive them from the school, few studies have examined caregiver strain in the context of school-based mental …

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, …

USF Tampa Graduate Theses and Dissertations

The quality of care in nursing homes has been evaluated from many varying perspectives, but few studies have analyzed quality in light of complaints made to state survey agencies by residents, their family members, or other individuals interacting with the nursing home. This study analyzed complaints, investigation of complaint allegations, and complaint-related deficiency citations to determine their effect, if any, on the quality of care in nationwide nursing homes. Using the Online Survey Certification and Reporting (OSCAR) survey dataset for facility characteristics and the complaint investigation dataset for outcomes of complaint investigation, analyses conducted included descriptives, correlations, conceptual mapping for …

Situating Contraceptive Practices And Public Health Strategy In The Bronx: Perspectives From Female Youth, Healthcare Workers, And Reproductive Health Leaders, Hannah Louise Helmy

USF Tampa Graduate Theses and Dissertations

In the United States, concerns about adolescent childbearing and its perceived corollaries – negative health outcomes for mother and child, the disintegration of the nuclear family, and “over-dependence” on public resources – began to circulate widely in policy spheres and popular media in the 1970’s, resulting in a proliferation of policies, programs, and services designed to address its prevention. Although national birth rates among adolescents are currently at their lowest since peaking in the early 1990’s, this decline masks persistent and significant disparities between groups of young people by race, ethnicity, geography, and poverty level. The concomitant existence of social …

Outcomes Of A Combined Mindfulness, Stuttering Modification, And Fluency Shaping Intervention For Children Who Stutter, Jennifer Kordell

USF Tampa Graduate Theses and Dissertations

A week-long intervention for five school-age children who stutter was implemented using techniques of fluency shaping, stuttering management, and mindfulness training. The purpose of this study was to investigate if children who stutter stuttered less frequently, stuttered with less struggle, and demonstrated changes in mindfulness measures after the completion of this week-long intervention. Pre- to post-treatment measures were analyzed by individual and group-level results. A comparative analysis between reading and narrative tasks was also performed. Findings indicate that three out of five children reduced the total number of disfluencies during the reading task, and two children reduced this total during …

The Relationship Between Nurses' Emotional Intelligence And Patient Outcomes, Mary Kutash

USF Tampa Graduate Theses and Dissertations

Heart Failure readmissions (HFR) significantly contribute to all cause hospital readmissions rates. Current evidence on the effectiveness of interventions for reduction of HFR is inconclusive. Recent research suggests that nurses’ emotional intelligence (EI) may be associated with better patient outcomes.

The purpose of this study was to examine if nurses’ EI is significantly related to HFR and if that relationship is mediated through patient satisfaction with care. One hundred and thirty six Registered Nurses were recruited from 11 in-patient units at a large teaching hospital in the south eastern United States. Two surveys were mailed to eligible participants; the Bar-On …
