The Development Of A Traumatic Brain Injury Bioreactor, Zachery Heller

Graduate Theses and Dissertations

Approximately 1.7 million Americans experience a traumatic brain injury (TBI) each year. Concussive injuries are a subset of TBI in which blows to the head cause the brain to collide against the interior of the skull. Damage to the neurons, supporting cells, and surrounding extra cellular matrix resulting from these collisions can lead to permanent physical, cognitive, and psychological impairment. We believe the prevalence and clinical significance of concussive injures warrants research investment. To study brain injury following TBI, in vivo models have been the gold standard for TBI experiments. Although a valuable research alternative, animals are expensive, raise ethical …

The Managerial Activities And Leadership Roles Of Five Achieving The Dream Leader College Presidents, Teresa Marie Mace

Graduate Theses and Dissertations

A significant increase in community colleges' (CC) presidential retirements is resulting in a huge loss of critical knowledge and experience. Recognition of this has led to numerous efforts and initiatives to prepare future community college leaders. These efforts have included numerous attempts to identify the competencies, skills, and leadership traits considered essential to performing the president's job. Unfortunately, most of the topics identified in self-reported assessments and personal interviews were not based on actual observations of what successful presidents do.

Unlike studies about community college presidents over the last 30 years, this study utilized Henry Mintzberg's (1968) structured observation methodology …

Design, Fabrication And Characterization Of Plasmonic Fishnet Structures For The Enhancement Of Absorption In Thin Film Solar Cells, Sayan Seal

Graduate Theses and Dissertations

Incorporating plasmonic structures into the back spacer layer of thin film solar cells (TFSCs) is an efficient way to improve their performance. The fishnet structure; which is a tunable, plasmonic light scatterer is used to enhance light absorption. Unlike other plasmonic particles that have been previously suggested, the fishnet is an electrically connected wire mesh and does not result in electric field localization, hence it results in greater absorption in the intrinsic Si layer. Unlike other designs, the fishnet structure is placed in the back spacer layer of the TFSC, so it does not block any incident light. There is …

An Open Source, Line Rate Datagram Protocol Facilitating Message Resiliency Over An Imperfect Channel, Christina Marie Smith

Graduate Theses and Dissertations

Remote Direct Memory Access (RDMA) is the transfer of data into buffers between two compute nodes that does not require the involvement of a CPU or Operating System (OS). The idea is borrowed from Direct Memory Access (DMA) which allows memory within a compute node to be transferred without transiting through the CPU. RDMA is termed a zero-copy protocol as it eliminates the need to copy data between buffers within the protocol stack. Because of this and other features, RDMA promotes reliable, high throughput and low latency transfer for packet-switched networking. While the benefits of RMDA are well known and …

Political Motive And Bail: The Effect Of Prosecutorial Strategies On Pretrial Decisions In Federal Terrorism Trials, Michael John Clanton

Graduate Theses and Dissertations

The purpose of this study is to understand how prosecutorial strategies affect pretrial decisions in U.S. terrorism trials and how pretrial decisions in turn affect the disposition of those trials. This research builds off of the work of Smith and Damphousse (1996) which compared terrorism indictees to traditional federal offenders. They found that the use of explicit politicality as a prosecution strategy was a significant predictor of both disposition and the sentence length in terrorism trials. This study focuses on the question of whether the use of an explicitly political prosecution strategy impacts pretrial decisions in terrorism cases and whether …

Electronic Theses and Dissertations

During field experience as a storyteller constructing a performance based on the Battle of Kings Mountain on behalf of the Overmountain Victory Trail Association and the Overmountain Victory National Historic Trail, I encountered ethical and philosophical dilemmas. This challenge centered on ethical and spiritual convictions that put me in potential conflict with the task of creating a performance about war. This experience forms the basis of an autoethnographic approach to the art form, revealing the critical role played by personal ethics and a functioning engagement with historiography and narrative theory in producing effective performance stories. Historical performance storytelling has little …

Mechanisms Of The Anti-Pneumococcal Function Of C-Reactive Protein, Toh B. Gang

Electronic Theses and Dissertations

Human C-reactive protein (CRP) increases survival of and decreases bacteremia in mice infected with Streptococcus pneumoniae. Such protection of mice against pneumococcal infection is seen only when CRP is administered into mice 6 hours before to 2 hours after the injection of pneumococci, but not when CRP is given to mice at a later time. Our first aim was to define the mechanism of CRP-mediated initial protection of mice against infection. It was proposed that CRP binds to phosphocholine (PCh) moieties present in the cell wall and activates the complement system on the pneumococcal surface that kills the pathogen. …

Ironic American Exceptionalism And The Myth Of The Open Self, Myron Moses Jackson

Dissertations

This work rethinks current interpretations of American exceptionalism, emphasizing dynamic relations, especially those we could call "ironic." I am reading Reinhold Niebuhr's The Irony of American History alongside Eric Voegelin's and Woodrow Wilson's philosophical and political treatment of freedom, expressed through the ideal of American personhood. American entertainment continues to spread globally, and the spreading creates a wider nexus of efficacious relations, allowing for the interplay of hidden relations and symbolic complexes. "Ironic American exceptionalism," as I call it, highlights the positive aspects, usually overlooked, provided by "virtual integration" and the spawning of novel cultural hybrids. By "virtual integration," I …
