Computational Analysis Of The Sir Mathematical Model For The Dengue Fever, Joseph Phillip Diaz

Theses and Dissertations

Dengue fever is a disease affecting people in more than 100 countries. Here we consider a host and vector model for the transmission of dengue fever. This SIR model consists of three compartments of susceptible, infective and removed for host (human) and two compartments of susceptible and infective for vector (dengue mosquitos). These five compartments yield five coupled nonlinear ordinary differential equations (ODEs). After non-dimensionalization, we have a system of three nonlinear ODEs. Reproductive number and two equilibrium points are calculated for various cases. Simulation is carried out for susceptible, infective and removed and the results are presented in graphical …

A Community-Based Participatory Approach To Understanding Health Beliefs, Policies, Barriers, And Solutions Related To The Health Disparities Of Marshallese Cofa Migrants In Arkansas., Pearl Anna Mcelfish

Graduate Theses and Dissertations

Public policies have different effects on different populations groups and can perpetuate health disparities among some populations. My research utilizes community-based participatory approach to research in the examination of one unique population: the Marshallese. This dissertation research presents three papers that are part of a cohesive research agenda predicated on community-based participatory research (CBPR) to facilitate policy-oriented learning. My research can be used to inform health policy, health care services, and health education. Chapter Two presents the article titled: Health Beliefs of US Marshallese Regarding Type 2 Diabetes.

This article explores the research question: what health beliefs related to diabetes …

Socially Constructing Drug Addicts From The Poor: A Critical Discourse Analysis, Kalynn Susan Amundson

Graduate Theses and Dissertations

Welfare drug testing was authorized by the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) of 1996, and has subsequently garnered extensive legislative interest in numerous states. This policy raises several questions, which are the subjects of the two journal articles and one manuscript included in this dissertation.

The first article addresses the question of a possible confluence of War on Drugs and Welfare Reform policies as evidenced through welfare drug testing policy, and indicated by continuity in policymakers’ rhetoric. This study examines federal-level policymakers’ debate discourse in these two policy streams. The analysis finds themes of the Social pathology, …

The Relationship Between Sleep And Nutrition In Message Framing Among College Students, Abbey G. White

Doctoral Dissertations

The college years are often depicted as a time of immense change, specifically in relation to college students' level of nutrition and sleep quality. However, these health concerns not only impact college students' health but also their academic performance, mood, and as a result their future. The primary purpose of this study was to determine whether technologically enhanced health messages are more effective than the traditional text format for creating healthy behavioral changes amongst college students. Secondly, the study provides the opportunity to examine previous research involving message framing, specifically, regulatory focus theory and self-efficacy, in order to provide further …

Students' Perspectives After Participation In A Mandated College Level Alcohol Intervention Program: A Phenomenological Study, Suzanna L. Guizar

Graduate Theses and Dissertations

Alcohol abuse among college students continues to be a significant problem by which the consequences impact the student, their peers, and the university. Although quantitative research with volunteer participants supports the use of enhanced brief motivational interventions and cognitive behavioral skills training in reducing risky drinking behavior (binge drinking), research with mandated students has shown inconsistent findings. The current study is a phenomenological qualitative study exploring the students’ perspectives after attending a mandated college-level alcohol intervention program. Mandated students are students who have been referred to an alcohol intervention as a result of violating an alcohol related policy on campus. …

Development And Preliminary Validation Of A Nonmedical Prescription Drug Motives Questionnaire, Lauren Ashleigh Milner

Graduate Theses and Dissertations

The prevalence of nonmedical prescription drug (NMPD) use continues to increase among emerging adult populations; however, little is known about the motivations behind this use. The current study aimed to extend previous research by developing and validating the first known comprehensive NMPD motives measure. As such, the primary focus of the current study was to examine evidence for the reliability and validity of the NMPD Motives Questionnaire by assessing the factor structure, internal consistency, and construct validity of the motives scale. Participants were drawn from a larger study of college student substance use behaviors and attitudes (N = 1,427; Mage= …

The Paleoepidemiology Of Malaria In The Ancient Near East, Nicole Elizabeth Smith

Graduate Theses and Dissertations

The end of the Late Bronze Age in the Near East (1300 - 1200 BCE) saw the widespread collapse of several large cultural centers, the reasons for which are a subject of continued debate. Evidence from events leading up to this cultural collapse suggest epidemic disease may have factored into the eventual downfall of these early civilizations. Recent DNA analysis from Egyptian mummies who lived during the period leading up to the Late Bronze Age collapse identified malaria in several elite individuals, suggesting the widespread prevalence of this infectious disease in Egypt. However, the exact prevalence, antiquity, and dynamics of …
