This thesis presents an end-to-end interference minimizing uniquely designed high performance I/O stack that spans multi-level shared buffer cache hierarchies accessing shared I/O servers to deliver a seamless high performance I/O stack. In this thesis, I show that I can build a superior I/O stack which minimizes the inter-application interference…

This research explores the impact of a service-learning project on the attitudes of the student participants. The study also investigates the impact of a service-learning project on the sense of efficacy and autonomy of the participants. Survey packets were administered to forty-three 3rd through 8th graders from a Nashville-area private school…

Schools in the United States have struggled with graduation rates for nearly 140 years. School divisions are continuously searching for new and creative curriculums to address changing student needs. From the U.S. Department of Education to local school board members, educators are working to discover creative and accountable alternatives to…

Emerging broadband wireless networks that support high speed packet data with heterogeneous quality of service (QoS) requirements demand more flexible and efficient use of the scarce spectral resource. Opportunistic scheduling exploits the time-varying, location-dependent channel conditions to achieve multiuser diversity. In this work, we study…

Caregiver burden and distress have been associated with informal caregivers. Research findings on the specific aspects of the caregiving role that influence burden are mixed. Factors such as amount of time per day giving care and specific characteristics about the disease progression have been linked to caregiver burden and distress. Other…

Self-regulated learning skills have been shown to positively impact academic achievement in educational settings. This same set of skills becomes critically important as graduates enter today's dynamic work environment. That environment increasingly requires accountants and other professionals to be lifelong learners. This study is a response to…

Low success rates in online mathematics courses at the community college level have raised concerns. The purpose of this study was to investigate the factors that contribute to student success in online mathematics courses at community colleges. The non-experimental quantitative design began with descriptive statistics to explore the quantitative…

This study examined the effects of the communication aspect of using an online grading program. This study explored teachers' perceptions of the implications of allowing the grading process to become transparent to parents. The purpose of this study was to assist teachers in searching for ways to create a positive parent-teacher relationship. A…

Black Student Unions (BSUs) in higher education represent a valued resource as they often engage in activities to recruit and retain students from underrepresented communities. Student groups in higher education, however, are beset by a variety of institutional and contextual complexities and complications that can impede or derail their growth.…

Worldwide, demand for education of all kinds is increasing beyond the capacity to provide it. One approach that shows potential for addressing this demand is facilitated video. In facilitated video, an educator is recorded teaching, and that video is sent to a remote site where it is shown to students by a facilitator who creates interaction…

College retention rates are a growing problem for many universities. Previous researchers focused on the inconsistencies between high school exit exams and college entrance exams, marginalized groups, and students with disabilities. However, a gap remains in the current literature regarding other external variables that may affect college…

This thesis studies several problems in information theory where the notion of causality comes into play. Causality in information theory refers to the timing of when information is available to parties in a coding system. The first part of the thesis studies the error exponent (or reliability function) for several communication problems over…

This dissertation examines the ways children use language to construct scientific knowledge in designed informal learning environments such as museums, aquariums, and zoos, with particular attention to autobiographical storytelling. This study takes as its foundation cultural-historical activity theory, defining learning as increased participation…

In Mexico, as in many other countries, HIV/AIDS strategies are developed at the federal level and implemented at the state level. Local programs are expected to use data, in particular surveillance data, to drive their decisions on programmatic activities and prioritize populations with which the program will engage. Since the early 1980s Mexico…

This study used a longitudinal study spanning a twelve-week time period and involving 165 undergraduate students to examine the combined impact of gender and impression management strategies on leader emergence by members relying on low versus high virtualness. The subjects were formed into 44 self-managed work groups and charged with completing…
