The Impact Of Personality And Affect On College Students' Motives For Marijuana Use, Lindsey W. Hawkins Jan 2006

The Impact Of Personality And Affect On College Students' Motives For Marijuana Use, Lindsey W. Hawkins

All-Inclusive List of Electronic Theses and Dissertations

Previous research has examined the relationship between motives for drinking and alcohol use. However, less research has been conducted on the relationship between motives for marijuana use and marijuana use/problems. This study attempted to examine what predictors of marijuana use and problems are mediated by motives for marijuana use. Prior research has identified several predictors of marijuana use including psychological distress, expectancies, sensation seeking, and various personality factors. In addition, previous studies have suggested that use-related problems are not merely a function of how much of a substance one consumes, but also one's motivation for using that substance. The current …

Factors Influencing The Importance Of Incorporating Competencies Regarding Mass Casualty Incidents Into Baccalaureate-Degree Nursing Programs As Perceived By Currently Employed Faculty, Kristin Whitty Jan 2006

Factors Influencing The Importance Of Incorporating Competencies Regarding Mass Casualty Incidents Into Baccalaureate-Degree Nursing Programs As Perceived By Currently Employed Faculty, Kristin Whitty

LSU Doctoral Dissertations

Whether they are naturally occurring, caused by environmental forces, or generated by humans, disasters have placed extraordinary stresses on society. Following September 11, 2001, the Department of Homeland Security was created to protect the nation and coordinate responses to future emergencies at the federal, state, and local levels. However, Governmental agencies can’t handle all aspects of mass casualty events. Healthcare professionals, such as nurses, who are knowledgeable and trained in mass casualty incidents (MCIs) are needed to provide competent care to the victims. Although others expect a knowledgeable nursing response, the majority of nurse educators have not received mass casualty …

Socioeconomic Characteristics Of Cancer Mortality In The United States Of America: A Spatial Data Mining Approach, Srinivas Kumar Vinnakota Jan 2006

Socioeconomic Characteristics Of Cancer Mortality In The United States Of America: A Spatial Data Mining Approach, Srinivas Kumar Vinnakota

LSU Doctoral Dissertations

Cancer is the second leading cause of death in the United States of America. Though it is generally known that cancer is influenced by environment, its relation to socioeconomic conditions is still widely debated. This research analyzed the spatial distribution of cancer mortalities of breast, colorectal, lung, and prostate, and their associated socioeconomic characteristics using association rule mining technique. The mortality patterns were analyzed at the county and health service area levels that corresponded to the years between 1999 – 2002 and 1988 – 1992, respectively. Distinct socioeconomic characteristics of cancer mortality were revealed by the association rule mining technique. …

Evaluating The Spatial Ecology Of Anthrax In North America: Examining Epidemiological Components Across Multiple Geographic Scales Using A Gis-Based Approach, Jason Kenna Blackburn Jan 2006

Evaluating The Spatial Ecology Of Anthrax In North America: Examining Epidemiological Components Across Multiple Geographic Scales Using A Gis-Based Approach, Jason Kenna Blackburn

LSU Doctoral Dissertations

This dissertation explores the spatial ecology and potential pathways of infection of anthrax, Bacillus anthracis, in North America. A multi-scale approach was used to evaluate the components required for disease agent survival in the environment, interactions with wildlife, and the potential role that vectors play in anthrax transmission. First, ecological niche modeling with the Genetic Algorithm for Rule-set Production (GARP) was used to predict the geographic distribution of anthrax in the continental U.S. using case data from outbreaks between 1957 and 2005. These results were then used to produce the first quantitative, continental scale predictions of anthrax in Mexico. At …

Radon In Caves: Clinical Aspects, Stephen A. Craven, Berend J. Smit Jan 2006

Radon In Caves: Clinical Aspects, Stephen A. Craven, Berend J. Smit

International Journal of Speleology

Historical, experimental and clinical evidence is presented to suggest that radon constitutes a relatively small carcinogenic risk for casual visitors to caves. The risk is dependent on radon levels and the smoking of tobacco. Show cave guides, chronically exposed to radon, may be at increased risk for lung cancer due to the effects of radon, especially if they are smokers of tobacco.

Isolation And Characterization Of Toxin A-Negative, Toxin B-Positive Clostridium Difficile In Dublin, Ireland, Denise Drudy, N. Harnedy, S. Fanning, R. O’Mahony, L. Kyne Jan 2006

Isolation And Characterization Of Toxin A-Negative, Toxin B-Positive Clostridium Difficile In Dublin, Ireland, Denise Drudy, N. Harnedy, S. Fanning, R. O’Mahony, L. Kyne

Articles

Clostridium difficile is a major cause of infectious diarrhoea in hospitalised patients. Most pathogenic C. difficile strains produce two toxins, A and B; however, clinically relevant toxin A-negative, toxin Bpositive (A– B+ ) strains of C. difficile that cause diarrhoea and colitis in humans have been isolated worldwide. The aims of this study were to isolate and characterise A– B+ strains from two university hospitals in Dublin, Ireland. Samples positive for C. difficile were identified daily by review of ELISA results and were cultured on selective media. Following culture, toxin-specific immunoassays, IMR-90 cytotoxicity assays and PCR were used to analyse …

Transposon Disruption Of The Complex I Nadh Oxidoreductase Gene (Snod) In Staphylococcus Aureus Is Associated With Reduced Susceptibility To The Microbicidal Activity Of Thrombin-Induced Platelet Microbicidal Protein 1, Arnold S. Bayer, Peter Mcnamara, Michael R. Yeaman, Natalie Lucindo, Tiffanny Jones, Ambrose L. Cheung Jan 2006

Transposon Disruption Of The Complex I Nadh Oxidoreductase Gene (Snod) In Staphylococcus Aureus Is Associated With Reduced Susceptibility To The Microbicidal Activity Of Thrombin-Induced Platelet Microbicidal Protein 1, Arnold S. Bayer, Peter Mcnamara, Michael R. Yeaman, Natalie Lucindo, Tiffanny Jones, Ambrose L. Cheung

Dartmouth Scholarship

The cationic molecule thrombin-induced platelet microbicidal protein 1 (tPMP-1) exerts potent activity against Staphylococcus aureus. We previously reported that a Tn551 S. aureus transposon mutant, ISP479R, and two bacteriophage back-transductants, TxA and TxB, exhibit reduced in vitro susceptibility to tPMP-1 (tPMP-1(r)) compared to the parental strain, ISP479C (V. Dhawan, M. R. Yeaman, A. L. Cheung, E. Kim, P. M. Sullam, and A. S. Bayer, Infect. Immun. 65:3293-3299, 1997). In the current study, the genetic basis for tPMP-1(r) in these mutants was identified. GenBank homology searches using sequence corresponding to chromosomal DNA flanking Tn551 mutant strains showed that the fourth gene …
