Factors That Predict Incident Reporting Behavior In Certified Registered Nurse Anesthetists, Nicole K. Damico

Theses and Dissertations

Improving patient safety through reduction of medical errors is a national priority. One of the strategies widely utilized to address this issue is the use of incident reporting systems. The purpose of this study was to describe factors that predict the likelihood that Certified Registered Nurse Anesthetists (CRNAs) will use incident reporting systems, guided by the theory of planned behavior (Ajzen, 1991). A non-experimental, correlational research design was utilized to achieve the study aims. Following IRB approval, a cross-sectional survey was administered electronically to a random sample of practicing CRNAs. Correlational analyses and a standard logistic regression were utilized to …

The Effect Of Sleep Medication Use And Poor Sleep Quality On Risk Of Falls In Community-Dwelling Older Adults, Yaena Min

Theses and Dissertations

The work presented in this dissertation focuses on the association between sleep medication use, poor sleep, and falls in community-dwelling adults 65 years or older. Sleep complaints and the consumption of medications to aid sleep are common in older adults. Psychotropic medications, such as sedative hypnotics, are associated with risk of falls in older adults. However, very few studies have assessed the impact of poor sleep and sleep medication use on the risk of falls in community-dwelling older adults. In the first project, a cross-sectional analysis of the Health and Retirement Study (HRS) 2010 data was conducted to determine the …

Results Twenty-eight and 190 low-income African American adult women participated in focus groups or interviews and a survey, respectively. In the qualitative study, positive deviants, who breastfed for at least four months, seemed to have stronger breastfeeding intentions, …

Novel Compounds As Potential Alzheimer's Disease Therapeutics And Inhibitors Of The Nlrp3 Inflammasome, Jeremy E. Chojnacki

Theses and Dissertations

Alzheimer’s disease is a devastating neurodegenerative disorder and the leading cause of dementia. The disease manifests via several pathologies including neuroinflammation, oxidative stress, metal ion dyshomeostasis, and cell death. To address the multifaceted nature of this disorder, the design of several diverse compounds, targeting many pathological effects, was generated. First, a series of compounds based on curcumin and diosgenin were synthesized following the bivalent design strategy. Two compounds were discovered to have neuroprotective ability, anti-oxidative function, and anti-Aß oligomerization (AßO) properties. A second set of molecules was also designed, wherein a hybrid compound strategy was utilized. Three hybrids were to …

Methods For Integrative Analysis Of Genomic Data, Paul Manser

Theses and Dissertations

In recent years, the development of new genomic technologies has allowed for the investigation of many regulatory epigenetic marks besides expression levels, on a genome-wide scale. As the price for these technologies continues to decrease, study sizes will not only increase, but several different assays are beginning to be used for the same samples. It is therefore desirable to develop statistical methods to integrate multiple data types that can handle the increased computational burden of incorporating large data sets. Furthermore, it is important to develop sound quality control and normalization methods as technical errors can compound when integrating multiple genomic …

Why Female Suicide Bombers? A Closer Look At The Liberation Tigers Of Tamil Eelam And Chechen Separatists, Latisha T. Campbell

Theses and Dissertations

The central hypothesis of this study is that terrorist organizations choose to use females as suicide bombers not only as tactical innovation but also to “signal” or send a message to various audiences. In order to meet the research objectives of this study, two terrorist organizations—the Liberation Tigers of Tamil Eelam and the Chechen Separatists or those individuals associated with the Chechen Resistance—are examined in detail from their inception through 2013 using a structured focused comparison methodology.

Evidence is found to support both of the studies’ main hypotheses. First, female suicide bombers are used by terrorist organizations because they are …

Dīpaṅkara Buddha And The Patan Samyak Mahādāna In Nepal: Performing The Sacred In Newar Buddhist Art, Kerry Lucinda Brown

Theses and Dissertations

Every four years, in the middle of a cold winter night, devotees bearing images of 126 Buddhas, Bodhisattvas, and other important deities assemble in the Nepalese city of Patan for an elaborate gift giving festival known as Samyak Mahādāna (“The Perfect Great Gift”). Celebrated by Nepal’s Newar Buddhist community, Samyak honors one of the Buddhas of the historical past called Dīpaṅkara. Dīpaṅkara’s importance in Buddhism is rooted in ancient textual and visual narratives that promote the cultivation of generosity through religious acts of giving (Skt. dāna). During Samyak, large images of Dīpaṅkara Buddha ceremoniously walk in procession to the …

Anaplasma Phagocytophilum Nutritional Virulence Mechanisms Target The Host Cell Secretory Pathway, Hilary Kay Truchan

Theses and Dissertations

Obligate intracellular pathogens must acquire host cell-derived nutrients to facilitate their survival. One such bacterial pathogen, Anaplasma phagocytophilum, replicates within neutrophils and non-phagocytic cells in a bacterial-modified, host cell-derived vacuole. The bacterium exploits host cell vesicular trafficking pathways to route nutrients to its vacuole and utilizes Rab GTPases, guanine nucleotide-dependent, vesicular trafficking regulators, to do so. We previously discovered that the A. phagocytophilum vacuolar membrane is decorated with a specific subset of Rab GTPases - Rab1, Rab4A, Rab10, Rab11, Rab14, Rab22A and Rab35. Rab1 is exclusively found on the endoplasmic reticulum (ER) and thus its localization suggests that the …

An Investigation Of The Differences Between Continuing And Non-Continuing Undergraduate Special Admission Students Related To Academic Advising Factors, Kevin P. Reeves

Theses and Dissertations

This study examined some differences between continuing and non-continuing special admission students in areas of academic advising in ways that are more systematic and thorough than past research. The premise of the study is that having a clearer understanding of how academic advising affects retention might provide colleges and universities with information to optimize the collegiate experience for special admission students. Therefore, research on the effect academic advising has on special admission student retention might offer insight into how the interactions between student and advisor affect retention issues.

A non-experimental descriptive research design was employed to investigate the differences between …

Isolation And Characterization Of Multipotent Lung Stem Cells From P53 Mutant Mice Models, Venkat Sundar Gadepalli

Theses and Dissertations

Recent advances in understanding lung biology have shown evidence for the existence of resident lung stem cells. Independent studies in identifying and characterizing these somatic lung stem cells have shown the potential role of these cells in lung repair and regeneration. Understanding the functional characteristics of these tissue resident stem/progenitor cells has gained much importance with increasing evidence of cancer stem cells, cells in a tumor tissue with stem cell characteristics. Lung cancer is most commonly characterized by loss of p53 function which results in uncontrolled cell divisions. Incidence of p53 point mutations is highest in lung cancer, with a …

Quantum Efficiency Enhancement For Gan Based Light-Emitting Diodes And Vertical Cavity Surface-Emitting Lasers, Fan Zhang

Theses and Dissertations

This thesis explores the improvement of quantum efficiencies for InGaN/GaN heterostructures and their applications in light-emitting diodes (LEDs) and vertical cavity surface-emitting lasers (VCSELs). Different growth approaches and structural designs were investigated to identify and address the major factors limiting the efficiency. (1) Hot electron overflow and asymmetrical electron/hole injection were found to be the dominant reasons for efficiency degradation in nitride LEDs at high injection; (2) delta p-doped InGaN quantum barriers were employed to improve hole concentration inside the active region and therefore improve hole injection without sacrificing the layer quality; (3) InGaN active regions based on InGaN multiple …

Inmates For Rent, Sovereignty For Sale: The Global Prison Market, Benjamin Levin

Publications

In 2009, Belgium and the Netherlands announced a deal to send approximately 500 Belgian inmates to Dutch prisons, in exchange for an annual payment of £26 million. The arrangement was unprecedented, but justified as beneficial to both nations: Belgium had too many prisoners and not enough prisons, whereas the Netherlands had too many prisons and not enough prisoners. The deal has yet to be replicated, nor has it triggered sustained criticism or received significant scholarly treatment. This Article aims to fill this void by examining the exchange and its possible implications for a global market in prisoners and prison space. …

The Capture Of International Intellectual Property Law Through The U.S. Trade Regime, Margot E. Kaminski

Publications

For years, the United States has included intellectual property ("IP") law in its free trade agreements. This Article finds that the IP law in recent U.S. free trade agreements differs subtly but significantly from U.S. IP law. These differences are not the result of deliberate government choices, but of the capture of the U.S. trade regime.

A growing number of voices has publicly criticized the lack of transparency and democratic accountability in the trade agreement negotiating process. But legal scholarship largely praises the 'fast track" trade negotiating system. This Article reorients the debate over the trade negotiating process away from …

The Story Behind A Letter In Support Of Professor Derrick Bell, Cheryl Nelson Butler, Sherrilyn Ifill, Suzette Malveaux, Margaret E. Montoya, Natsu Taylor Saito, Nareissa L. Smith, Tanya Washington

Publications

Professor Derrick A. Bell, Jr. had a long and proud history of disturbing authority. He is widely noted as one of the founders of Critical Race Theory. His scholarship on race was not only a direct challenge to the traditionally conservative legal academy, but also to the more liberal bastions within the academy, such as the Critical Legal Studies movement. His writings about the role of race in American law have made him one of the most prominent legal scholars of a generation.

However, Professor Bell did not merely write about racial injustices. He was willing to take risks to …

The Geography Of Racial Stereotyping: Evidence And Implications For Vra ‘Preclearance’ After Shelby County, Christopher S. Elmendorf, Douglas M. Spencer

Publications

The Supreme Court in Shelby County v. Holder (2013) effectively enjoined the preclearance regime of the Voting Rights Act. The Court deemed the coverage formula, which determines the jurisdictions subject to preclearance, insufficiently grounded in current conditions. This Article proposes a new, legally defensible approach to coverage based on between-state differences in the proportion of voting age citizens who subscribe to negative stereotypes about racial minorities and who vote accordingly. The new coverage formula could also account for racially polarized voting and minority population size, but, for constitutional reasons, subjective discrimination by voters is the essential criterion. We demonstrate that …

The Administrative State's Passive Virtues, Sharon B. Jacobs

Publications

Fifty years ago, Alexander Bickel famousy suggested that courts use tools like standing, ripeness, and the political question doctrine to avoid reaching the merits of difficult cases. Yet despite the increasingly central role of administrative agencies in government, there have been no efforts to date to apply Bickel's insights to the bureaucracy. This Article remedies that deficit. The Article provides a three-part taxonomy of administrative restraint and offers case studies from federal agencies such as the Federal Energy Regulatory Commission, the Environmental Protection Agency, and the Fish and Wildlife Service. It argues that agencies sometimes use restraint strategically for reasons …

[Dis-]Informing The People's Discretion: Judicial Deference Under The National Security Exemption Of The Freedom Of Information Act, Susan Nevelow Mart, Tom Ginsburg

Publications

As noted by President Obama's recent Review Group on Intelligence and Communications Technologies, pervasive state surveillance has never been more feasible. There has been an inexorable rise in the size and reach of the national security bureaucracy since it was created after World War II, as we have gone through the Cold War and the War on Terror. No one doubts that our national security bureaucracies need to gain intelligence and keep some of it secret. But the consensus of decades of experts, both insiders and outsiders, is that there is rampant overclassfication by government agencies. From its inception in …

Too Strict?, Richard B. Collins

Publications

Should the strict scrutiny standard govern judicial review of claims that government has burdened religious freedom? American law’s patchwork of rules applies that demanding standard to some claims but denies any meaningful review to others. A major difficulty is that most claims alleging denial of religious freedom depend on beliefs that cannot be reviewed by secular courts. Claims based on allegations alone shift the burden to the defending government. Strict scrutiny purports to make justification very difficult; governments are supposed to lose most cases. A second defect of the test in religious freedom cases is its failure to consider harm …
