College of Graduate Studies: Theses & Dissertations

The Center for Disease Control and Prevention estimated that there are 1.6-3.8 million sports related traumatic brain injuries in the United States annually which occur in both mainstream and extreme sports. Many of these concussions have been associated with collisional sports, like football, but high risk extreme sports, like motocross, also have many opportunities for collisions to occur. Unlike traditional varsity sports motocross races, especially at the amateur level, do not require more than advanced life support at a race in case of emergency situation leaving the amateur rider to recognize and decide on concussion management. Purpose of this study …

Perceptions Of Delinquency Among Male Athletes And Non-Athletes: A Qualitative Investigation, Humphrey Nartey

College of Graduate Studies: Theses & Dissertations

It is presumed that the involvement in sports helps to deter delinquency, yet athletes who seemingly have it all engage in destructive delinquent lifestyles (Savini, 2008). Many theorists contend that the "jock identity" or "sport hubris" is largely responsible, as people think they will be treated more favorably if they are athletes (Miller et al., 2006). This perception raises the question of whether athletes know and understand the constructs of delinquency. Thus the purpose of this study was to examine male athletes' and non-athletes' perceptions of the minor and major substrates of delinquency. A semi-structured interview was used to gather …

Inquiry, Efficacy, And Science Education, Heather Christa Scott

College of Graduate Studies: Theses & Dissertations

Developing learners who are equipped to think critically about the vast information circulating around them is essential in their preparation for a role in society today. The use of effective inquiry-based instruction is not a widespread practice among K-12 classrooms. Many secondary and post-secondary science instructors see the valuable link between students asking questions and the development of critical thinking. Inquiry-based instruction provides student opportunities to ask questions, design methods of investigation, gather information, and finally reach conclusions based on evidence. However, this instruction style is rarely used in the classroom, particularly in elementary classrooms. This study examines the relationships …

Neural Network-Based Optimal Control Of Mobile Robot Formations With Reduced Information Exchange, Travis Dierks, Bryan Brenner, S. Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

A novel formation control scheme for mobile robots is introduced in the context of leader-follower framework with reduced communication exchange. The dynamical controller inputs for the robots are approximated from nonlinear optimal control techniques in order to track the designed control velocities generated by the kinematic controller. The proposed nonlinear optimal control technique, referred to as adaptive dynamic programming, uses neural networks (NNs) to solve the optimal formation control problem in discrete time in the presence of unknown internal dynamics and a known control coefficient matrix. A modification to the follower's kinematic controller is used to allow the desired formation …

Knowledge, Attitudes And Practices Of Environmental Justice In Higher Education, Marjorie M. Nussbaum

College of Graduate Studies: Theses & Dissertations

Research suggests that issues of environmental justice are not being routinely included in the curriculum of the K-12 classroom and that teachers in those grades do not feel prepared to teach it. Likewise, little has been written about the addition of these topics to higher education coursework, leaving the question of inclusion at this level of education as well. This apparent lacuna may point to at least one reason why K-12 teachers are neither knowledgeable about environmental justice nor prepared to teach it. To discover the current state of inclusion in higher education, a mixed methods study was conducted to …

Parent Expectations Of Elementary Schools And The Leaders, Teachers, And Staff: An Examination Of Elementary Schools In A Southeastern Georgia School District, Ella B. Green

Application Of Self-Monitoring For Situational Awareness, Christopher Trickler

College of Graduate Studies: Theses & Dissertations

Self-monitoring devices and services are used for physical wellness, personal tracking and self-improvement. These individual devices and services can only provide information based on what they can measure directly or historically without an intermediate system. This paper proposes a self-monitoring system to perform situational awareness which may extend into providing insight into predictable behaviors. Knowing an individual’s current state and likelihood of particular behaviors occurring is a general solution. This knowledge-based solution derived from sensory data has many applications. The proposed system could monitor current individual situational status, automatically provide personal status as it changes, aid personal improvement, contribute to …
