The main goal of this workshop was to create a conversation about mental wellness at the JUCO level, as a majority of research was done …

Voltage-Gated Potassium Channel Dependent Mechanisms Of Cardiovascular Adaptation To Chronic Exercise., Sean Raph

Electronic Theses and Dissertations

Exercise increases cardiac workload, escalating the demand for oxygen. The myocardial vasculature responds to the greater demand for oxygen by increasing blood flow to match the needs of the heart during augmented work. Increasing blood flow requires the coronary arteries dilate (a.k.a. vasodilation); this is mediated predominantly by vascular smooth muscle cell relaxation. Vasodilation is driven through inhibition of calcium influx into vascular smooth muscle cells. The prevention of calcium influx is largely mediated by efflux of potassium via potassium channels causing membrane hyperpolarization, which in turn closes voltage-dependent (or gated) calcium channels (VDCC). Changes in vascular smooth muscle cell …

The Graduate Record Examination And Graduate Admissions: Issues In Diversity, Lauren Rankin

Dissertations

Doctoral education is an expensive and difficult endeavor. Program faculty are interested in finding students who will be successful in completing their courses and obtaining employment. The Graduate Record Examination (GRE) is often used to assess a student’s readiness for the rigors of graduate education. A student’s readiness for doctoral education can be assessed through analyzing the predictive validity of the GRE with various outcomes such as grade point average, scholarly output, and time to completion. However, this measure may not predict success for all students with potential bias towards students who are international and linguistically diverse. A total of …

Mathematical Knowledge For Teaching As Decision-Making For The University Mathematician Developing Coherence In Review Of Discrete Mathematics, Julie Lang

Dissertations

Mathematicians teaching at the university level have a deep understanding and appreciation for the mathematics that they teach. However, they rarely receive much formal training in teaching. Thus, university mathematicians must rely on their mathematical understandings and personally developed ideas of teaching to guide their decision-making. Relatively little research exists on mathematicians’ teaching practices. The purpose of this study was to examine the mathematical knowledge for teaching (MKT) of a university mathematician teaching discrete mathematics and how he leveraged his knowledge to make decisions and develop coherence among mathematical ideas during a semester review. An enactivist perspective examining a mathematician’s …

Political Astuteness Of Nurse Educators, Gail Marie Hanson Brenner

Dissertations

Nurses comprise the largest segment of the healthcare workforce. Although nurses have advocated for patients since Florence Nightingale’s time, advocating for changes in health policies that affect populations on a larger scale has not changed over time (Rasheed et al., 2020). Professional nursing associations, nurse educators, and the Institute of Medicine have all identified the need to educate nurses in advocacy and health policy. With the recent revision of the American Association of Colleges of Nursing’s Essentials publication, health policy has moved from an essential to a featured concept that is found in the competencies and subcompetencies of the domains. …

Estimating The Distribution Of Ratio Of Paired Event Times In Phase Ii Oncology Trials, Li Chen, Mark Burkard, Jianrong Wu, Jill M. Kolesar, Chi Wang

Markey Cancer Center Faculty Publications

With the rapid development of new anti-cancer agents which are cytostatic, new endpoints are needed to better measure treatment efficacy in phase II trials. For this purpose, Von Hoff (1998) proposed the growth modulation index (GMI), that is, the ratio between times to progression or progression-free survival times in two successive treatment lines. An essential task in studies using GMI as an endpoint is to estimate the distribution of GMI. Traditional methods for survival data have been used for estimating the GMI distribution because censoring is common for GMI data. However, we point out that the independent censoring assumption required …

The Effect Of Numeracy And Math Anxiety On Whole Number Bias, Jasmine Jessica Leanna Bonsel

Electronic Theses, Projects, and Dissertations

Whole number bias (WNB) has been defined as the tendency to apply natural number knowledge to rational numbers. This misapplication can often lead to erroneous responses in mathematical tasks and understanding of rational number properties. Whole number bias can be explored using Dual Processing Theories. According to Dual Processing Theory we have two types of thinking: Type I and Type II. Type I is fast, heuristic based, intuitive, and doesn’t require working memory, while Type II is slow, logic based, analytical, and requires working memory. Some researchers argue that WNB is an intuitive phenomenon and occurs from a failure to …

Power In Portrayal: An Exploration Of The Evolving Cold War Relationship Between Germany And America Through Film, Kaleb Wentz

Electronic Theses and Dissertations

The end of the Second World War brought many questions to the United States. One of the greatest among these was what to do with defeated Germany. Many clamored for the dissolution of the former Nazi State and the shameful humbling of its people while others recognized the value of a revitalized Germany as an ally against the looming threat of an emboldened and empowered postwar Soviet Union. Though retribution held sway immediately following the war, the Cold War consensus of an alliance with West Germany and a reimagining of the German people as victims rather than perpetrators won out …

Borderline Personality Disorder And Violent Crime: The Moderating Role Of Sex And Race, Genevieve Allison

Electronic Theses and Dissertations

People receiving treatment for substance use disorders (SUD) are at risk of justice involvement. Although it is well-established that borderline personality disorder (BPD) increases risk for criminal involvement, it is unclear whether this relationship exists among people with SUDs. Furthermore, prior research has found sex and race differences in the relationships between BPD and justice involvement as well as violence, but these moderators have not been explored within a substance using sample. The current study utilized a sample receiving SUD treatment to examine whether BPD is associated with prior violent charges and, if race and sex moderated this relationship. Results …

After-School Connectedness, Racial–Ethnic Identity, Affirmation, And Problem Behaviors, Danielle A. Augustine, Emilie Smith, Dawn P. Witherspoon

Journal of Youth Development

After-school programs are potential contexts that may promote positive youth development (PYD) and reduce problem behaviors among African American children. One way after-school programs may be associated with reduced problem behaviors is by fostering an affirming sense of identity. Prior research on racial–ethnic identity among African American children and adolescents has shown that a positive and affirming sense of identity is related to less maladaptive coping, yet little is known about how after-school programs may foster an affirming sense of identity and lead to reduced problem behaviors. The current study adds to this discourse by investigating how children’s connection to …

A fourth of the global seabed sediment volume is buried at depths where temperatures exceed 80 °C, a previously proposed thermal barrier for life in the subsurface. Here, we demonstrate, utilizing an extensive suite of radiotracer experiments, the prevalence of active methanogenic and sulfate-reducing populations in deeply buried marine sediment from the Nankai Trough subduction zone, heated to extreme temperature (up to ~120 °C). The small microbial community subsisted with high potential cell-specific rates of energy metabolism, which approach the rates of active surface sediments and laboratory cultures. Our discovery is in stark contrast to the extremely low metabolic rates …

Potential Fitness Trade-Offs Of Elevated Esterase Activity Associated With Insecticide Resistance In The Mosquito Culex Quinquefasciatus, Timothy Schulte

Electronic Theses, Projects, and Dissertations

One of the current major issues in the control of vector-borne disease is resistance to insecticides. Resistance to one or more insecticides has appeared in over 580 different arthropod species. Widespread resistance has led to the field of Insecticide Resistance Management (IRM). The goal of IRM is to develop insecticide-use strategies that prevent or slow down the evolution of resistance. Computer models have shown that more effective IRM strategies rely on the assumption that resistance carries a fitness cost in the absence of insecticide use.

In the mosquito Culex quinquefasciatus resistance to certain organophosphate insecticides is caused by an increased …
