Exercise Adherence: Motivational Factors Influencing Exercise Adherence And Fitness Level, Justin Recklau Apr 2007

Exercise Adherence: Motivational Factors Influencing Exercise Adherence And Fitness Level, Justin Recklau

Undergraduate Theses and Capstone Projects

There are many factors that influence adherence to an exercise program. This research study aimed to determine which factors most effectively ensured adherence, with the hypothesis that no single factor was indicative of exercise adherence as adherence is a dynamic item. The results target exercise professionals to assist them in retaining clientele and encouraging clientele to adhere to exercise programs. A survey was implemented that had clients self-report their stage in the transtheoretical model as well as how strongly they felt about five positive factors to exercise as well as five barriers to exercise. In addition to surveys, body composition, …


Mathematical Methods In Composing Melodies, Thomas Brown Apr 2007

Mathematical Methods In Composing Melodies, Thomas Brown

Undergraduate Theses and Capstone Projects

This thesis, “Mathematical Methods in Composing Melodies,” explores the different ways in which mathematics can be used to create music. Some research has been done in this field already. Richard F. Voss and John Clarke used fractals and different frequencies of noise to create music. The Greek composer Iannis Xenakis used Markovian Stochastic trees to create some of his compositions. Explored in this thesis are seven different methods to compose melodies. After compiling the different melodies, they were categorized by different musical periods based on the musical characteristics found in the melody. This thesis differs from other research that deals …


Downstream Pathway Activation In Cultured Hepatocytes Following Treatment With Francisella Tularensis, Nicole Wakefield Apr 2007

Downstream Pathway Activation In Cultured Hepatocytes Following Treatment With Francisella Tularensis, Nicole Wakefield

Undergraduate Theses and Capstone Projects

Francisella tularensis, the intracellular pathogen that causes tularemia, was investigated to determine how it infects and replicates within mammalian hepatocytes. To date, it has been shown that hepatocytes can be infected by F. tularensis and that this causes considerable change in the protein phosphorylation state of several vital signaling molecules within the host cell. Protein kinase pathways can be mapped as signatures of infection. Hepatocytes tend to be susceptible to infection by F. tularensis, thus stimulating internal signaling. The Francisella strains used were selected with the goal of producing a model that can be used to elucidate the cell signaling …
