The Ncaa’S Losing Battle: What Happens When Paying Student-Athletes Meets Title Ix?, Lisa M. Scott

Southern Illinois University Law Journal

Compensating student-athletes is no longer a far-fetched idea.  Lawsuits against the National Collegiate Athletic Association (NCAA) are gaining traction in federal courts, and the NCAA will soon be required to adjust its regulations regarding student-athlete compensation.  Any potential compensation must be given to both male and female student-athletes in substantially proportionate numbers under Title IX of the Education Amendments of 1972.  The Office of Civil Rights (OCR) determines what constitutes substantially proportionate numbers under Title IX, and therefore, the OCR will determine if collegiate institutions are providing proportionate compensation to student athletes.

This Comment argues that allowing collegiate institutions to …

The Use Of Choice To Reduce Negative Reactions To Online Interstitial Advertising, Paul Vogt

Graduate Research Theses & Dissertations

This thesis investigates choice as a way of reducing the negative reactions people have toward advertising. Specifically, online interstitial advertisements are examined when participants have a choice of commercials. Results indicate that choice, sex, and the advertisement itself interact to reduce measures of reactance (i.e., anger and negative cognitions). Intrusiveness is shown to be negatively associated with attitudes toward the brand and attitudes toward the advertisement when participants had a choice of advertisements. Cognitive responses were shown to be positively related to attitudes toward the advertisement and anger was shown to be negatively associated with attitude toward the brand.

Testing The Equality Of Mean Functional Kinetic Energy Profiles Of Males And Females Using The Bootstrap, Todd Buretz

Graduate Research Theses & Dissertations

Functional data analysis (FDA) is an important technique that allows discrete data to be treated as continuous. Using FDA, data can be smoothed in order capture specific patterns as well as leaving out unwanted noise which aids in analysis. In order to smooth physical activity data, leave-one-out cross-validation can be used to calculate the smoothing parameter for each individual subject. Pseudo-data is then generated using the bootstrap resampling technique. The mean functions from the pseudo-data as well as the observed data are then compared against each other to calculate the significance of the mean functional profiles for males and females.

Coparenting Among Intact Families With Young Adolescents : Associations With Internalizing And Externalizing Symptoms, Andrew Joseph Flannery

Graduate Research Theses & Dissertations

There is growing evidence that the coparenting relationship maintains a strong influence on child psychological wellbeing, however this influence has not been as widely studied in relation to adolescent outcomes. Additionally, adolescent perspectives of their coparents' relationship have not been examined using a U.S. sample from intact families. Adolescence is a period rife with novel stressors and an increased risk for poor mental health outcomes. Thus, it is important to examine contextual family factors, such as the coparenting relationship, that have demonstrated an influence on psychosocial outcomes during other early stages of development. Extant evidence suggests that the coparenting relationship …

Relationships Among Principal Leadership Behaviors, Teachers' Motivation, And Teacher Job Satisfaction, Thomas C. Lind

Graduate Research Theses & Dissertations

Certain transformational and transactional leadership behaviors exhibited by principals are effective in creating a work environment that supports teacher autonomy and higher levels of teacher job satisfaction. In an age of school reform and increased pressures on teachers to improve student performance, few studies have examined the relationships between principal leadership behaviors, teacher motivation, and teacher job satisfaction. The current study used data gathered from principals to examine the relationships between a principal's transformational and transactional leadership practices and a teacher's autonomous and controlled motivations. In addition, the relationship between a principal's leadership practices and a teacher's level of job …

High Let Radiation Modulates Autophagic Flux In Glioblastoma Cells, Van Ai Bui

Graduate Research Theses & Dissertations

Glioblastoma (GBM) are highly malignant brain cancers that arise from the astrocytes of the brain. A diagnosis of GBM forecasts a poor prognosis even with the prescription of aggressive therapy consisting of surgery and radiation therapy with temozolomide. The average survival time with therapy is only 15 months with near universal recurrence. New therapeutic approaches are urgently needed to overcome recurrence. Radiation therapy is a highly effective treatment modality prescribed for brain cancer. Energy metabolism is altered in cancer cells and GBM in particular compared to normal surrounding cells. A major adaptation to the altered metabolism in GBM cells is …

Empowering Courts In Corporate Law, Julian Velasco

Journal Articles

Corporate law recognizes the twin duties of care and loyalty, but treats the two very differently. Cases involving the duty of care receive very deferential review under the business judgment rule, if any at all, in light of exculpation provisions in corporate charters, while cases involving the duty of loyalty receive more demanding review under the entire fairness test. A fiduciary has the duty to act in the interests of the beneficiary in all relevant respects." In other words, both care and loyalty, as well as any other fiduciary duties that exist, are all merely aspects of the one overarching …
