Doctor of Philosophy / Department of Hospitality Management and Dietetics / Carol W. Shanklin / This study used two operational research components to explore strategies to decrease waste in university dining facilities. Component one assessed students’ beliefs and behaviors toward food waste in a selected dining center. The relationships between students’ food waste behavior, sustainability beliefs, and demographics were evaluated with the use of a self-administered survey and continual food waste monitoring. This study also assessed whether simple prompt-type message interventions had an impact or if the addition of more personally relevant feedback-based data elicited a greater change in consumer beliefs and behaviors On average, more than 57 grams of edible food was left on each tray. Food waste behaviors were not influenced by demographic factors. Individuals with higher levels of food waste beliefs also disposed of less edible food items. The simple prompt-type messages stimulated a 15% reduction in food waste. The addition of more personalized feedback-based messages did not stimulate a change above that of the prompt message. These findings indicate that simply making university students aware of the topic of food waste may be useful in improving their behaviors. Component two evaluated the operational feasibility of implementing tray free dining at Kansas State University Dining Services. Telephone interviews with managers of university dining facilities involved in tray free dining were conducted to identify best practices. Focus groups of students were used with a written survey to gain insight into their perceptions of tray free dining. Benefits included: decreased waste, reduced chemical, resource, and food costs, and improved student satisfaction. Managers identified complaints and dining room cleanliness as negative outcomes. Student involvement, education, and communication were strongly recommended by both managers and students. This research supports the recommendation to consider the implementation of tray free dining at Van Zile. Decreased costs, improved satisfaction, and positive public perception are likely positive outcomes.

Master of Science / Department of Hospitality Management and Dietetics / Elizabeth B. Barrett / The Centers for Disease Control estimates that each year 48 million Americans become ill, 128,000 are hospitalized, and 3,000 die of foodborne diseases. In 2011, the CDC reported that Norovirus caused the majority of all foodborne diseases and can be eliminated with proper handwashing, which is the number one way to prevent the spread of foodborne disease. The purpose of this study was to use the Health Belief Model to determine differences in university foodservice employees’ beliefs and perceptions about handwashing and foodborne illness. The constructs of perceived susceptiblity, severity, barriers, benefits, and self-efficacy as they relate to handwashing were used to examine the differences in demographics. Instrument development included a review of literature, focus group feedback, a pilot study and a review by industry experts. The final instrument was distributed to all foodservice employees at Kansas State University using Qualtrics and pen-and-paper surveys. Frequencies, means, t-tests, ANOVA, and regression were used for data analysis and to answer research questions. Results indicated respondents who were older (above 23 years of age), full-time employees, had more than three years of experience, and were food safety certified had a higher perception of susceptibility, benefits, and self-efficacy of handwashing and its relationship to reducing foodborne illness. Perceived severity was highest among respondents with food safety certification and more than three years of experience. Supervisor/Manager category did not agree on barriers to handwashing in the workplace with other positions; however, most employees did not rate barriers as a problem. Non-white respondents showed a lower self-efficacy for ability to wash hands correctly. Results of this study highlight the need for self-efficacy focused handwashing training for first year and non-white employees.

The purposes of this study were. to identify current uses of computers by university foodservice operations and to determine if there.are any differences in computer use among university foodservice operations. The twelve university foodservice directors who responded to the research questionnaire varied significantly in their computer usage and computer characteristics. Institutions serving more than 1,000 meals per day represented 91% of the sample using computers. Chi Square analysis found a significant use of menu-costing programs. The computers were used more than six hours a day by 75% of the sample. The.problems relating to hardware and software selection indicate a lack of assessment of operational needs for foodservice operations. Guidelines to assist foodservice directors in computerization are needed.
