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 …

Factors Impacting Vocational Rehabilitation Employment Outcomes: An Analysis Of State-Federal Service Provision, Valerie Jeannette Rodriguez

Theses and Dissertations - UTB/UTPA

State-federal vocational rehabilitation (VR) programs are widely recognized for providing various services to individuals with disabilities to help them reach their goals of independence and employment. Because rehabilitation programs are required to meet federal and state goals, standards, and indicators, thorough and ongoing program evaluation is necessary to identify predictors of successful and unsuccessful employment outcomes in order to determine best practices in vocational rehabilitation service delivery.

In the large southwestern state examined in this research study, there is an estimated return on investment of $9 for each dollar spent on successful VR cases. Cases closed successfully by state-federal VR …

Personality Of Personal Trainers: A Study Of Perception And Preference, Andy L. Chasse

Theses and Dissertations - UTB/UTPA

This study used a personality questionnaire to address the lack of literature concerning how the general population perceives personal trainers and what qualities they desire in them. The Big Five Inventory (BFI) with two demographic items (gender and previous experience) was administered to 130 undergraduate students at The University of Texas-Pan American to determine perceived and desired characteristics. High extraversion was most commonly associated with personal trainers. High extraversion, agreeableness, and conscientiousness, as well as low neuroticism, were most desired in personal trainers. Significant differences were seen between perceived and desired means across all dimensions. Additionally, gender produced main effects …

Secondary Complications Among Person's With Spinal Cord Injury And Best Practices For Life Care Planners, Noel A. Ysasi Jr.

Theses and Dissertations - UTB/UTPA

The current study was intended to deliver life care planners with a guide as to whether or not secondary complications (SCs) should be included within the LCP, while obtaining the professional opinion of physiatrists as to the incidence rate of SCs. Each research question was designed to determine whether differences exist between life care planners (LCPs) and physiatrists in their knowledge regarding SCs while comparing their responses with empirical research. In addition, it was determined to investigate whether costs should be included in a LCP based on the reports given from certified and non-certified LCPs; even though it meets the …
