An Analysis Of The Interaction Of Methylphenidate And Nicotine In Adolescent Rats: Effects On Bdnf, Elizabeth D. Freeman Aug 2015

An Analysis Of The Interaction Of Methylphenidate And Nicotine In Adolescent Rats: Effects On Bdnf, Elizabeth D. Freeman

Electronic Theses and Dissertations

This investigation was an analysis of the interaction of adolescent exposure to methylphenidate (MPH; trade name: Ritalin) on nicotine sensitization and conditioned place preference (CPP) in a rodent model and underlying mechanisms of this effect. Animals were treated IP with 1 mg/kg MPH or saline using a ―school day‖ regimen of five days on, two days off, from postnatal day (P) 28-50. During the final two weeks of MPH treatment, animals were either behaviorally sensitized to nicotine (0.5 mg/kg free base) or saline for 10 days, or conditioned to nicotine or saline using the CPP behavioral paradigm. In addition, three …


An Investigation Of The Relationship Between A Static Jump Protocol And Squat Strength: A Potential Protocol For Collegiate Strength And Explosive Athlete Monitoring, Cody Haun Aug 2015

An Investigation Of The Relationship Between A Static Jump Protocol And Squat Strength: A Potential Protocol For Collegiate Strength And Explosive Athlete Monitoring, Cody Haun

Electronic Theses and Dissertations

The purpose of this study was to examine the relationship between estimated absolute and relative squat strength and a static jump protocol with potential to provide desirable training adaptation data to practitioners in the field of collegiate strength and conditioning. Forty-one young (20.80 ± 2.44 years), healthy volunteers reported estimated back squat 1RM’s based on the most recent training block and completed a static jump protocol. Males (n=19, est. 1RM 141.29 ± 32.02kg) and female (n=22, est. 1RM 71.56 ± 19.64kg) jump data revealed large to very large correlations between squat strength, mean jump heights of jumps and other calculated …

An Examination Between High And Low Optimistic Ncaa Division I Student-Athletes' Perceptions Of Preferred Leadership Behavior In Sport: A Qualitative Investigation, Alexander C. Roorda Jan 2015

An Examination Between High And Low Optimistic Ncaa Division I Student-Athletes' Perceptions Of Preferred Leadership Behavior In Sport: A Qualitative Investigation, Alexander C. Roorda

Electronic Theses and Dissertations

Numerous researchers have examined preferred sport leadership behaviors from both the coach and athlete perspectives (Beam, Serwatka, & Wilson, 2004; Chelladurai, & Carron, 1983; Freakley, Czech, Harris, & Burdette, 2012; Turman, 2013; Weinburg, & Gould, 2010). However, there is limited research in student-athlete personality dispositions and how those might influence student-athlete perceptions of preferred leadership behaviors. The purpose of the present study was to examine views of leadership in light of certain personality dispositions. This research examined the potential influence of optimism (Abramson, et al, 2000) on qualitative descriptions of preferred leadership behaviors using the Revised Leadership Scale for Sport …


Body Image Self-Discrepancies And Compulsive Exercise: Exploring The Role Of Approach And Avoidance Motivational Selves, Kristin A. Chandler Jan 2015

Body Image Self-Discrepancies And Compulsive Exercise: Exploring The Role Of Approach And Avoidance Motivational Selves, Kristin A. Chandler

Electronic Theses and Dissertations

According to Brewer, Davis, Kalmbach, Kaptein, Katzman and Kirsch (1997), problematic exercise occurs in approximately 80% of anorexia nervosa patients and 55% of bulimia nervosa patients. Thus, a comprehensive understanding of unhealthy exercise is necessary for its assessment as well as eating disorder prevention and intervention. One term used to describe unhealthy exercise is compulsive exercise. Although compulsive exercise has been regarded as problematic in the development, treatment, and outcome of eating disorders, little research has investigated the risk factors for this behavior. Given the influence of body image disturbances on disordered eating and the relationship between compulsive exercise and …


A Qualitative Examination Of The Sport Music Preferences Of Ncaa Division I Athletes, Zachary Ryan Jan 2015

A Qualitative Examination Of The Sport Music Preferences Of Ncaa Division I Athletes, Zachary Ryan

Electronic Theses and Dissertations

Athletes report listening to music prior to their sport participation for a number of reasons, including: mood-regulation, arousal control, and concentration (Laukka & Quick, 2011; Sorenson, Czech, Gonzalez, Klein, & Lachowetz, 2008; Stevens & Lane, 2001). Researchers have found that many athletes report their music preferences for everyday listening are different from what they listen to around sport participation (Laukka & Quick, 2011). Music preferences have been found to be related to both gender and aspects of an individual’s personality, such as aggression (Rentfrow & Gosling, 2003; Colley, 2008; Rubin, West, & Mitchell, 2001;). The purpose of the current study …


Female Social Rank And Steroid Production In Semi-Free Ranging Lemur Catta On St. Catherines Island, Georgia, Tiffany Burgess Jan 2015

Female Social Rank And Steroid Production In Semi-Free Ranging Lemur Catta On St. Catherines Island, Georgia, Tiffany Burgess

Electronic Theses and Dissertations

Many mammalian species live in complex social groups that profoundly affect the behavior and ecology of their members. In ring-tailed lemurs (Lemur catta) these groups are characterized by female dominance, where females have priority over males for food, grooming, and space. Among females there is also a linear dominance hierarchy. L. catta have a strong matrilineal social core due to females staying within their natal group and males dispersing at sexual maturity. Daughters “inherit” their mother’s social rank. However, it is not known if the matrilineal lines are maintained through learned dominant/aggressive behavior or inherited via genetically determined hormonal …
