Adapting To Obstacles: Inhibition And Creative Potential In A Sample Of Successfully Aging Older Adults, Cassandra Dinius

Dissertations

Studying older adults who are aging ‘successfully’ (i.e., avoiding disease/disability; maintaining high cognitive and physical functioning; engaging in meaningful interpersonal/social engagement) may offer insight into variables that contribute to cognitive change throughout the lifespan. Successful aging is related to levels of engagement, which may be promoted by the problem solving and reevaluation encouraged by the creative process (Fisher & Specht, 1999). Creative thinking requires the consideration of diverse concepts and strategies (e.g., generating many solutions), as well as the regulated filtering of these possibilities (e.g., neither too permissive nor too narrow when eliminating ideas; Baas, De Dreu, & Nijstad, 2011). …

Translated Evidence-Based Mental Health Toolkit For Skilled Nursing Facilities, Natalie Crisostomo Barrales, Jan Martha Conducto, Cecelia Ly-Peh

Occupational Therapy | MSOT Capstone Projects

More than 500,000 adults with a serious mental illness (SMI) receive long term care (LTC) in a skilled nursing facility (SNF) (Grabowski, Aschbrenner, Feng, & Mor, 2009). Residents who live in SNFs may experience limited access to meaningful occupations. The SNFs’ institutionalized structure may perpetuate a lack of autonomy and stigma for residents with a SMI (Sullivan & Williams, 2017). Occupational therapy (OT) services provided in a SNF are often limited to therapeutic exercises, therapeutic activities, and activities of daily living skills (Rafeedie, Metzler, & Lamb, 2018). OT practitioners are not utilizing mental health interventions. Although SNFs are not traditionally …

A quantitative design utilizing multiple regression analysis was used to test the null hypothesis in this study. The data was collected using the procedures …

Organizational Effects Of Exogenous Corticosterone On Vocal Development In A Wild Parrot, Rory Eggleston

Theses and Dissertations

Songbirds learn songs during a plastic phase in vocal development, similar to human vocal babbling. Research has focused on male song learning, a process influenced by gonadal steroids. Like humans, parrots are very plastic vocal learners and both sexes learn vocalizations throughout life. It is unclear how the endocrine system mediates environmental information with developing phenotypes in parrots. Corticosterone (CORT) is a sex-neutral hormone that can affect cognitive development, but its role in vocal development has not been experimentally tested in wild parrots. I quantified vocal babbling from nestling Green-rumped Parrotlets (Forpus passerinus) recorded in Venezuela. Nestlings received oral CORT-oil …

Discrimination Of Monozygotic Twins Using Dna Methylation Levels Of One Cpg Site At Chromosome 3, Dino O. Robinson

Student Theses

Conventional STR typing, commonly used in forensics for human identification, poses a problem in criminal cases and paternity disputes involving monozygotic (MZ) twins because they share identical DNA sequences. To date, no routine method is available in forensics to differentiate between individuals of MZ pairs. Recently, epigenetic methods measuring differential DNA methylation patterns have been applied to MZ twin differentiation. In this study, we investigated the potential to identify MZ twins using a previously identified DNA methylation site in chromosome 3, cg18562578, in a sample of 129 MZ and 37 dizygotic (DZ) twin pairs. We used bisulfite converted saliva DNA …

Hypothalamic Circuits Mediating Consumption And Anxiety, Ryan Cassidy

Dissertations and Theses (Open Access)

From 1960-2016, U.S. obesity prevalence increased 13-40% and diabetes increased from 3-15%. There is an epidemic of metabesity, the aggregate metabolic disorders produced by chronic overeating. Drugs for metabesity were developed in the 1930s with limited effectiveness; agents today rely on the same principles and are similarly ineffective. Particularly surprising has been the failure of satiety enhancers; this indicates it may not be that physiologic hunger drives chronic overeating. Although hunger and satiety affect traditional reward circuitry (Cassidy & Tong 2017), evidence for the primacy of this effect is mixed. Being hungry reduces anxiety-like behavior in mice; whether the …

Microbiological Safety Of Halal Beef In The United States, Omar Ahmed Al-Mahmood

All Dissertations

Halal foods, foods permissible per Islamic law, are a fast-growing segment of the global food industry. Most microbiological evidence about halal foods is from studies conducted in Muslim-majority countries not western (Muslim-minority) countries. We aimed to determine the microbiological quality of halal beef at both slaughter and retail in the southeastern United States as well as explore the role of Halal Certifying Bodies (HCBs) in overseeing implementation of food safety practices. The study was informed by two main hypotheses: (1) microbial load will be lower in the post-evisceration slaughter stage of beef carcass samples; (2) indicator organisms will be higher …

Investigating Metal-Mediated Dna Damage Prevention By Antioxidants And Examining The Role Of Metals In Fluconazole-Mediated Dna Damage, Andrea A. E. Gaertner

All Dissertations

Reactive oxygen species (ROS) play an important role in the development of many diseases. Common assays to test the ability of hydrophobic compounds to prevent oxidative stress are radical scavenging assays and cell studies. However, these radical assays often do not accurately reflect biological outcomes, and the use of different cell lines limits the ability to directly compare compound efficacy (Chapter 1). Results from DNA damage prevention assays can directly compare antioxidant efficacy, but these assays have been limited to water-soluble compounds. Chapter 2 discusses the first assay that quantifiably evaluates the ability of hydrophobic compounds to prevent metal-mediated DNA …

Just as the issue has largely been created by the environment and the people within it, it also greatly affects the environment and people. Many people throughout the …

How Does Grading Schools Impact Florida’S Teachers And Students? The Need For A New Approach To School Accountability, Luke Aubry Kupscznk

Graduate Doctoral Dissertations

In 1999, Florida began grading schools on an A to F scale. These grades constituted part of the A+ package of policies advanced by Governor Bush’s administration. Schools then earned grades based on student standardized test scores. These changes followed a decade of increasing dismay over the trajectory of American education and preceded national moves towards test-based accountability for students and schools. While many researchers have investigated the effects of high-stakes testing on students, few have looked at the impacts of school-level accountability on non-test outcomes. This study considers the impacts of receiving a failing-grade on variables other than test …

Public-Private Partnerships In Education: A Vertical Case Study Of The Right To Education Act (2009), India, Sheetal Gowda

Graduate Doctoral Dissertations

One of the most contentious issues that elicits heated debates in the field of international and comparative education is the role of private actors in the provision of educational services using public monies. As the programmatic idea of public-private partnerships (PPPs) gains momentum internationally, educational PPPs has emerged as a key strategy in reducing educational and social inequities. Despite growing research evidence suggesting the contrary, the neo-liberal agenda of positioning PPPs as the best mechanism for achieving educational rights enshrined in international declarations and national constitutions continue to be perpetuated. Of particular relevance to this study is Section 12(1)(c) of …

Characterization Of Microbial Communities Across Disease States And Environmental Conditions In Kemp’S Ridley (Lepidochelys Kempii) And Green Sea Turtles (Chelonia Mydas), Kerry L. Mcnally

Graduate Doctoral Dissertations

All species of sea turtles are threatened or endangered, with various diseases and conditions affecting populations around the world. Understanding healthy populations as well as populations beset by disease conditions, such as fibropapillomatosis and cold-stunning, could lead to helpful tools in the conservation management and medical treatment needed to protect these species. Microbial communities, or the microbiome, at different body sites of sea turtles likely play important roles in the health of these animals, from aiding in digestion to immune system regulation. Disruption of these communities, either through disease and/or environmental factors, may play a role in disease processes and …

Bilateral Muscle Oxygenation Kinetics In Response To Repeat Sprint Cycling In Strong And Weak Individuals, John Abbott

Electronic Theses and Dissertations

Repeat sprint ability has been investigated thoroughly, however optimal training methodology to improve RSA remains elusive. Both kinetic and physiological viewpoints have been used to scrutinize aspects of RSA including, initial sprint performance (anaerobic power), maximal cardiorespiratory fitness (VO2max), lactate threshold, anaerobic capacity (mean power), muscle activation (EMG), and local muscle oxygenation kinetics. To our knowledge no study has utilized maximal strength levels as a separate factor among a homogenous group of cardiorespiratory fitness individuals (as determined by peak VO2 during RSA). The purpose of this study was to better understand the relationship between maximal strength, muscular characteristics, and cycling …
