Wrong-Way Driving: A Regional Approach To A Regional Problem, Md. Omar Faruk

Electronic Theses and Dissertations

Wrong-way driving (WWD) has been problematic on United States highways for decades despite its rare occurrence. Since WWD crashes are rare, recent researchers have studied WWD non-crash events such as WWD 911 calls and WWD citations to understand the overall nature and trend of WWD. This paper demonstrates the regional nature of the WWD problem and proposes regional transportation systems management and operations (Regional TSM&O) solutions to combat this problem. Specifically, it was found that 11% of all WWD multi-data events (e.g., multiple 911 calls for the same WWD event) traveled from one county to another. Additionally, 30% of all …

Development And Application Of Microelectrodes To Study In Situ Disinfectant Loss And Corrosion On Metal Surface, Xiangmeng Ma

Electronic Theses and Dissertations

An Analytical Investigation Of Prestressed Beam Bridge Performance Before And After Widening, Chris Oriordan Adjah

Electronic Theses and Dissertations

As traffic and congestion increase, so does the likelihood of collisions. The solution to this problem is usually through a rehabilitation process with two primary options: (1) widening/expansion of existing roadway and bridges and (2) complete replacement (new construction) of roadway and bridges. The first option is the most feasible and cost-effective. While roadway widening/expansion pose minimal issues, the same cannot be said of bridge widening. An existing bridge presents a multitude of challenges during the planning and design phases, during construction, and throughout the structure's service life. Special attention is required in both the design and detailing of the …

Faculty Knowledge And Readiness In Reporting Student Victimization Disclosure And Title Ix Compliance, Abigail Malick

Electronic Theses and Dissertations

The U.S. Department of Education and Title IX Educational Act of 1972 shaped the way institutions of higher education address and prevent student victimizations. The law originally sought to eliminate sex-based discrimination in education but has evolved to include sexual misconduct. Since the Dear Colleague Letter of 2011, the position of institutions has changed significantly in the way they address student victimization as it relates to dating violence, sexual assault, and stalking (Rosenthal, 2017). One requirement is that institutions inform and train Responsible Employees to report when a student discloses experiencing sexual misconduct, including dating violence, sexual assault, or stalking. …

Examining The Motivations And Benefits Of Student-Athletes Performing Community Service., Matthew Ryan Huml

Electronic Theses and Dissertations

With over 460,000 active student-athletes (NCAA, n.d.), the student sub-population is large enough to investigate potential options for institutions to increase their academic achievement. Additionally, participating in academic-related activities is especially important because of concerns about student-athletes spending more than the 20 hours per week the NCAA allows for working on their sport (Wolverton, 2008). Studies frequently highlight a lack of effort by student-athletes to adjust to academic opportunities and expectations within higher education (Adler & Adler, 1991; Lally & Kerr, 2005; Levine, Etchison, & Oppenheimer, 2014; Miller & Kerr, 2003).
