Transmission Of Panulirus Argus Virus 1 (Pav1) And Its Effect On The Survival Of Juvenile Caribbean Spiny Lobster, Mark J. Butler Iv, Donald C. Behringer Jr., Jeffrey D. Shields

Biological Sciences Faculty Publications

The Caribbean spiny lobster Panulirus argus, an important fisheries species, is host to Panulirus argus virus 1 (PaV1), a lethal, unclassified virus-the first found in any species of lobster-prevalent in juvenile lobsters. We describe a series of laboratory experiments aimed at assessing the likely modes of disease transmission, determining the survival of lobsters relative to each transmission pathway and identifying potential alternate hosts. Given evidence for lower prevalence of PaV1 in large lobsters, the effect of lobster size on susceptibility was also examined. Results demonstrated that PaV1 can be transmitted to juvenile lobsters via inoculation, ingestion of diseased tissue, contact …

A Study Of The Distribution And Abundance Of The Adult Malaria Vector In Western Kenya Highlands, Li Li, Ling Bian, Guiyun Yan

Political Science & Geography Faculty Publications

Background: A sharp rise in the malaria mortality rate has been observed recently in western Kenya. Malaria is transmitted by mosquito vectors. Malaria control strategies can be more successful if the distribution and abundance of mosquito vectors is predicted. However, how mosquito vectors are distributed in space remain poor understood, and this question is rarely studied using spatial methods. This study aims to provide a better understanding of the distribution and abundance of mosquito vectors. To achieve this objective, spatial and non-spatial methods were employed. The data on the distribution of adult mosquitoes, and mosquito breeding habitats in a study …

Advancing Epidemiological Science Through Computational Modeling: A Review With Novel Examples, Scott M. Duke-Sylvester, Eli N. Perencevich, Jon P. Furuno, Leslie A. Real, Holly Gaff

Biological Sciences Faculty Publications

Computational models have been successfully applied to a wide variety of research areas including infectious disease epidemiology. Especially for questions that are difficult to examine in other ways, computational models have been used to extend the range of epidemiological issues that can be addressed, advance theoretical understanding of disease processes and help identify specific intervention strategies. We explore each of these contributions to epidemiology research through discussion and examples. We also describe in detail models for raccoon rabies and methicillin-resis-tant Staphylococcus aureus, drawn from our own research, to further illustrate the role of computation in epidemiological modeling.

Challenge Course Effectiveness: The Impact On Leadership Efficacy And Work Efficacy Among College Students, Theresa Odello, Eddie Hill, Edwin Gomez

Human Movement Sciences & Special Education Faculty Publications

Challenge courses have become increasingly popular in recent years. Many groups are turning to half-day challenge courses due to time and financial constraints. Yet, few studies have quantified the benefits of a half-day course. The purpose of this study was to examine the effects of participation in a four-hour challenge course on leadership efficacy and work efficacy of college students. Pretest, posttest, and follow-up questionnaires were utilized. T-test analyses found that participating in a challenge course has a significant positive effect on increasing one’s leadership and work efficacy from pretest to posttest, after participation in a four-hour challenge course. This …

Continence Care: The Need For Creativity And Innovation, Karen A. Karlowicz

Nursing Faculty Publications

(First paragraph) In April 2007, I attended a conference quite different from anything I had previously experienced. The conference, Innovating for Continence: The Engineering Challenge, was hosted by the Simon Foundation for Continence. As the title implies, this was not your usual conference about the diagnosis, treatment, and management of urinary incontinence. Rather, it was a conference dedicated to exploring technological advances in continence care. The central question throughout this two-and-a-half day event was, "What can be done to simulate continence technology to ensure the most effective management for persons who suffer with this problem?"
