The Academic And Behavioral Impact Of Multiple Sport Participation On High School Athletes, Christopher James Kohl

Dissertations

For many high school student athletes, there is increased pressure to specialize in one sport, to participate at a high level, and to play year-round (Brenner, 2016). This increased emphasis on sport specialization has led to a proliferation of overuse injuries, overtraining, and burnout (Brenner, 2016). Sport specialization significantly contributes to overuse injuries, which account for almost half of all sport injuries (Andrews & Yaeger, 2013). This research was designed to clarify if there are significant differences in the behavioral and academic performance of student athletes who compete in one sport and student athletes who compete in multiple sports. Six …

Exercising Their Privilege To Borrow: A Demonstrated Understanding Of The Obligation Of Student Loans In A Community College, Joan M. Meyer-Barrett

Dissertations

The costs associated with attending a community college have increased over the years, not unlike most sectors within higher education (Mitchell & Leachman, 2015). As such, community college students often find borrowing student loans a necessity in order to seek the academic credential they intend (McKinney & Backscheider Burridge, 2015). In recent years, it is community college students who stop or drop out without completing an academic credential, with little increased earning potential, who are at high risk of defaulting on their student loan balance (McKinney & Backscheider Burridge, 2015). While enrolled in college, these students are at-risk for completing …

Third Party Reforms In Corrections: A Qualitative Analysis Of Interest Groups’ Effectiveness At Reducing Entropy Using Litigation, James M. A. Pitts

Dissertations

Interest groups have been prevalent in American society for decades. Much of interest groups’ (IGs) influence has been examined by their effect on decision-making. IGs’ ability to affect policy choices is undeniable both legislatively and judicially. Analyses of judicial decision-making generally focus on the use of amicus curiae briefs (ACBs) by IGs. While most analyses of IGs’ influence have been conducted using quantitative methods, few have assessed IGs’ effect on decision-making qualitatively. Although the literature on IGs and decision-making is well established among political scientists, these concepts have been discussed much less among criminologists. The current analysis fill this void …
