Barrett, The Honors College Thesis/Creative Project Collection
Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.
Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

Description
The objective of this randomized, single-blind crossover study was to examine the effect of vinegar on the blood glucose response to meal ingestion. This study was associated with a companion study Is Apple Cider Vinegar Effective for Reducing Heartburn Symptoms Related to Gastroesophageal Reflux Disease. Glucose meters were utilized to measure blood glucose levels immediately prior to, and at four ½ hour intervals following meal ingestion. Previous studies have demonstrated that vinegar modulates the meal-time glucose response. Hence an alternative hypothesis was used: that a significant difference will be observed between the control and the vinegar groups. The results from the study were not significant likely due to a small sample size. The test meal eaten with a drink composed of vinegar diluted in water appeared to be most effective at decreasing the overall change in postprandial blood glucose. The vinegar drink also played a role in decreasing the peak glucose level at 30 minutes post-meal.

Physical activity as a health or nutrition related intervention might stimulate appetite and increase hunger due to increased energy expenditure. This study analyzed the effect of a postprandial 15-minute walk on the hunger and energy intake of 10 obese, pre-diabetic adults. Subjects participated in three 4-hour trials: a walk treatment (consume highly glycemic meal, walk for 15 minutes at a moderate pace, and rest for 4 hours), a fiber treatment (consume highly glycemic meal enriched with soluble fiber and rest for 4 hours), and a control treatment (consume highly glycemic meal without fiber and rest for 4 hours). The effects of each treatment on hunger and energy intake were measured using a Likert scale analysis (ranging from "completely satisfied" to "extremely hungry") at 4 hours post-treatment and pre/ post 24-hour dietary logs. The results showed no significant increase or decrease on hunger or energy intake for both the walk and the fiber treatment compared to the control treatment. This denies the idea that physical activity might increase short-term hunger, and supports the use of physical activity as a viable nutrition related intervention tool.

Description
With obesity and metabolic diseases reaching epidemic levels, it is important to find ways to increase physical activity and improve diet. Previous studies have shown that improvements in mood can increase desire to perform physical activity, and that vitamin C intake is linked to improvements in mood. Based on this, two hypotheses were formed and tested to investigate the effect on physical activity levels and mood states from vitamin C supplementation at a dose of one gram per day in the form of a novel functional food. Thirty-one college students or faculty at Arizona State University were screened from a pool of applicants and placed into either a vitamin C or placebo group; all participants received the novel functional food to eat daily for four weeks. Serum levels of vitamin C, weight, height, BMI, body fat percentage, mood, and physical activity were measured before and after the functional food intervention. Vitamin C changed significantly through the course of the study in the experimental group. Baseline data for participants showed a positive correlation between vitamin C status and vigor, and a negative correlation between vitamin C status and weight and BMI. Physical activity was not related to vitamin C status, according to baseline data, and it did not significantly change over the course of the study. The results indicate that variance in BMI can be attributed to vitamin C status, but the study should be refined and tested again.

Description
Background: The American Heart Association has created an Official 2012 Hands-Only CPR Instructional Video that is approximately one minute in length and has been viewed over 600,000 times on YouTube. Objective: To evaluate the video's effectiveness in teaching adolescents aged 12-17 hands-only CPR. Methodology: The study took place in the Phoenix metropolitan area. Study participants were recruited from high schools, junior high schools and the Tempe Boys & Girls Club. The 100 study participants took a short, four question survey and watched video on either a laptop computer or video projector. Participants were then subjected to a cardiac arrest mock scenario in which they were tested on calling 911, compression rate, compression depth, and hand placement using a Lifeform CPArlene Recording Manikin. In analysis of the data, subjects were separated into four groups: 12-14 year olds (middle school aged) who had previous CPR training (MSG-T), 12-14 year olds with no previous training (MSG-U), 15-17 year olds (high school aged) who had previous training (HSG-T) and 15-17 year olds with no previous training (HSG-U). Results: Every study participant performed hands-only CPR during the mock scenario. Between the two middle school-aged groups, the MSG-U was more likely to call 911 during the mock scenario (P<0.05). There were no significant differences in compression rate and depth between the MSG-U and MSG-T. Between the two high school-aged groups, the HSG-T was more likely to call 911 during the mock scenario (P<0.05). There was no significant difference in compression rate between the HSG-T and HSG-U groups. The HSG-T compressed the chest significantly deeper than the HSG-U group (P<0.05). The HSG-T was the only group to statistically be on par with the AHA recommended 100 compressions/minute (P<0.05). All other groups were significantly below the 100 compressions/minute standard. No groups were statistically on par with the AHA recommended compression depth of two inches. Conclusion: The Official 2012 Hands-Only Instructional Video should not be used as a definitive training tool to teach school-aged adolescents hands-only CPR. This video, as well as other similar training videos, would be useful as introductory tools for children 12-14 years of age or as a refresher for older children who have received previous training.
