Why Giving Up The Keys Can Be Terrifying: Examining Driving Retirement Through A Terror Management Theory Paradigm, Perri Navarro

Dissertations

Driving retirement, or giving up the keys, is a current topic of interest in the gerontological literature. Most adults will outlive their ability to drive safely, yet do not plan for driving retirement, although planning for driving retirement appears to result in better outcomes. The current study examined the possibility that older adults avoid driving retirement because it is a mortality prime (reminder of death), as well as the possible role of implicit self-esteem in buffering against mortality concerns specifically in an older adult population. Participants in the current study (n=90) were randomly assigned into one of three …

The Impact Of The Use Of Science Notebooks In Conjunction With A Learning Progression-Based Science Unit In An Urban Middle School, Reagan Williams

Dissertations

Learning progressions are the latest tool to understand the ways science learning occurs and they underlie the structure and framework of the Next Generation Science Standards.Prior research indicated a variety of ways to develop and validate learning progressions and learning progression’s general positive impact on students’ science learning. However, no study has explicitly employed science notebooks as the cornerstone to the development and/or validation processes.

Estimating Wasi Iq Scores To Assist In Identifying Elementary School Gifted Students, Debra Garrett Pregler

Dissertations

Identifying gifted students early is important so they may receive adaptations in their learning environment including admittance into gifted programs (Subotnik, Olszweski-Kubilius, & Worrell, 2012). An effective method to increase the likelihood of identifying gifted students is needed (Pfeiffer, 2003). Admission at the elementary level primarily uses the individually-administered intelligence test; yet, the test is only administered to students nominated to the gifted program. The purpose of this study was to determine if individually-administered IQ test scores were related to specific information available to the elementary school counselor to aid in the determination of unidentified gifted elementary school students who …

It examined whether clinicians were more likely to diagnose PTSD in a Black or White man due to …

Examining The Relationship Between Posttraumatic Stress Symptoms And Posttraumatic Growth: Pathways To Thriving In The Face Of Adversity, David Strasshofer

Dissertations

Research has largely focused on the negative physical and psychological consequences of trauma exposure. In contrast, posttraumatic growth is a relatively recent addition to our understanding of people’s response to life’s struggles. Posttraumatic growth (PTG) is conceptualized as positive changes in a person’s life following a cognitive struggle in the aftermath of trauma. However, PTG research is a relatively nascent line of empirical inquiry and there are several major unanswered questions about the construct and its utility. Part of this is due to conflicting findings related to the relationship between PTG and psychological distress and adaptive significance. The current study …

Myosin Assembly Into Elongating Thick Filaments Is Dependent On The Function Of Conserved Apmk-Related Kinase Unc-82 In C. Elegans, Natasha R. Schiller

Dissertations

The mechanism of assembly of sarcomeric myosins into elongating thick filaments is not well understood. The results of this study suggest a novel mechanistic model in which the AMPK-related kinase UNC-82, which is orthologous to mammalian ARK5/NUAK1 and SNARK/NUAK2, acts as an assemblase on sarcomeric myosin molecules, mediating their addition into the elongating thick filaments of C. elegans body-wall muscle. The classical genetic crosses performed in this study produced over 53 different worm strains that contain thick-filament-affecting mutations and/or transgenes in single-, double- or triple-mutant combinations. The phenotypes of these strain were documented and analyzed using viability assays, brood analysis, …

A 3d Simulation Of Leukocyte Adhesion In Blood Flow, Tai-Hsien Wu

Dissertations

It has been widely acknowledged that further understanding about the dynamics between blood cells and blood flow can help us gain more knowledge about the causes of diseases and discover more effective treatments. Examples of such dynamics include red blood cell (RBC, or erythrocyte) aggregation, white blood cell (WBC, or leukocyte) margination, and WBC extravasation. WBC extravasation is an important multiple-step process in the inflammatory response and therefore has drawn considerable attention over the past two decades. In this multiple-step process, a WBC undergoes at least four steps, including capture, rolling, firm adhesion, and transmigration, and each step is influenced …

Seismic measurements began with one or two linear refraction spreads, used to establish …

Effects Of Multi-Day Music Enrichment On Salivary Cortisol And Cage Behavior In Shelter Dogs, Stacy D. Engerbretson

Dissertations

Rehoming shelters provide their animals with environmental enrichment with the expectation that modifying the physical space will improve kennel-related stress and subsequently abate undesirable behaviors. Although enrichment has shown moderate success at improving in-kennel behavior, increased use of physiological measurements of stress, such as cortisol, has garnered doubt as to which canine behaviors are truly elicited by a biological state of distress. Consequently, it is unknown if past examples of successful kennel enrichment decreased biological stress in addition to affecting behavior. This study explored music’s effect on salivary cortisol and music’s potential as a long-term, kennel enrichment strategy. Shelter dogs …

Teaching Matching-To-Sample To Low-Performing Children With Autism, Blaire E. Michelin

Dissertations

Matching-to-sample is a basic procedure used in most programs for pre-school children with autism. However, a few children fail to acquire this skill with standard matching-to-sample procedures. Therefore, the purpose of this study was to evaluate an alternative method for teaching matching-to-sample to those children when the traditional methods are likely to fail. First, simple discriminations with the matching materials were taught, then the discriminations were made more complex across successive sessions. Initially, all discriminations were taught using bins to separate the comparison stimuli. All three children acquired matching-to-sample, which generalized to matching novel two-dimensional stimuli, not placed in bins.

Behavioral Contrast Using A Simulated Organizational Task, Brandon M. Ring

Dissertations

The purpose of the present study was to bridge a gap between Organizational Behavior Management (OBM) and the Experimental Analysis of Behavior (EAB). Although OBM’s historical and scientific roots are nested within EAB, OBM research does not always strictly follow or adhere to basic research definitions or procedures. That is, terms that have specific operational definitions in EAB and Applied Behavior Analysis are sometimes used incorrectly in OBM research. Similarly, these terms are often associated with specific experimental procedures in basic literature, yet OBM research procedures may not follow the strict procedural guidelines. The purpose of the present study was …

Three Essays On Asset Price Bubbles, Frank Ofori-Acheampong

Dissertations

This dissertation examines various issues associated with asset price bubbles. In the first essay, a Markov regime-switching model with time-varying transition probabilities is developed to identify asset price bubbles in the S&P 500 Index. The model nests two different methodologies; a state-dependent regime-switching model and a Markov regime-switching model. Three bubble regimes are identified; dormant, explosive, and collapsing. Time-varying transition probabilities are specified for each of the nine possible transitions in the Markov regime-switching model. Estimation of the model is done using conditional maximum likelihood with the Hamilton filter. Results show that transition probabilities depend significantly on trading volume and …
