In this study it is proposed to survey ten selected school lunch programs in Bryan County, Oklahoma, in order to determine a sound procedure for the operation of a successful school lunch program. the increasing knowledge of nutrition as an element in the scholastic progress of children is a factor that the school administrator must consider.

The problem involved in this thesis is to examine the organization, administration, and equipment of the school kitchens, and point out certain educational values derived from such a project.

Background: National School Lunch Program (NSLP) meals have been found to be of higher dietary quality than home-packed lunches. Objective: To explore the cost, including time, of NSLP versus different categories of home-packed lunches. Methods: Data from pre-kindergarten and kindergarten lunches from three schools in southwest Virginia were used for this study. Each lunch item was priced, and a direct cost was assigned based on the lunches contents. Time assessments were conducted to determine the amount of time to prepare each lunch, with a monetary value for time computed based on average salary of the respective county. A non-parametric Kruskal Wallis test was used to compare the direct cost, time, time cost, and the full cost of the meals. Medians were computed based on outlier data. Results: The lowest median direct cost was found for homemade packed lunches ($1.55), followed by homemade school lunches ($2.11), then convenience packed lunches ($2.12), and then NSLP lunches ($2.15). When incorporating preparation time, the NSLP lunch cost the least ($2.15), followed by convenience packed lunches ($2.56), then homemade packed lunches ($2.92), and then homemade school lunches ($11.32). Seventy-six percent (n=414) of home-packed lunches contained sugar-sweetened beverages and/or dessert food items, accounting for almost one-quarter (21.8%) of the cost of all home-packed lunches. Conclusion: When time is computed as part of the total cost of NSLP versus home-packed lunches, the NSLP is the least expensive option. In conjunction with the nutritional benefits of the NSLP, this time-cost data may help shift purchasing and consumption patterns. / Master of Science / Background: National School Lunch Program (NSLP) meals served at school have been found to be healthier than home-packed lunches. Objective: To investigate the differences in cost, including time, among NSLP lunches and different categories of home-packed lunches. Methods: Data from pre-kindergarten and kindergarten lunches from three schools in southwest Virginia were used for this study. Each lunch item was priced, and a direct cost was given based on the items in each lunch. Researchers then made each lunch or recorded packaging preparation times to determine the amount of time to prepare each lunch, with a value for time given in dollar form based on average salary of the respective county. A non-parametric Kruskal Wallis test was used to compare the direct cost, time, time cost, and the full cost (i.e. direct cost + time cost) of the meals. The data is based on medians to give a better representation of the data. Results: The lowest median direct cost was found for homemade packed lunches ($1.55), followed by homemade school lunches ($2.11), then convenience packed lunches ($2.12), and then NSLP lunches ($2.15). When incorporating preparation time, the NSLP lunch cost the least ($2.15), followed by convenience packed lunches ($2.56), then homemade packed lunches ($2.92), and then homemade school lunches ($11.32). Seventy-six percent (n=414) of home-packed lunches contained sugar-sweetened beverages and/or dessert food items, accounting for almost one-quarter (21.8%) of the cost of all home-packed lunches. Conclusion: These results show an interesting difference in lunch cost based on category when considering cost and time. Given the research on the health benefits of NSLP meals over home-packed lunches, the cost data may help shift purchasing and eating patterns among parents of school-age children.

Objectif. Étudier les comportements alimentaires des enfants utilisateurs de boîte à lunch tels que décrits par les mères, en s’inspirant des descripteurs de comportements alimentaires de Jean-Pierre Poulain. Méthodes. Des entrevues individuelles et de groupes eurent lieu avec 18 mères. Une analyse de données qualitatives a été réalisée en utilisant les dimensions de Poulain comme cadre de référence. Une considération additionnelle fut intégrée dans l’analyse, celle de la dimension matérielle de la boîte à lunch. Résultats. Dimension spatiale : Les repas ont lieu dans des classes ou dans de grandes salles communes. Dimension temporelle : Le moment et la durée de la consommation du repas varient selon différents facteurs. Le moment de préparation de la boîte est aussi d’intérêt. Environnement social : Les pairs et les médias ont une grande influence dans les comportements liés à la boîte à lunch. Logique de choix : La mère est le principal décideur et acteur à l’égard du contenu. Structure de la prise : Les mères précisent des contenus associés aux repas de la veille ou des mets froids. Des desserts et des à-côtés accompagnent le repas principal. L’étude de la dimension matérielle de la boîte révèle que la facilité d’entretien est le principal critère de choix des boîtes alors que l’apparence visuelle est celui de l’enfant. L’écologie devient de plus en plus une priorité. Conclusion. Cette nouvelle approche pour l’étude des comportements alimentaires du jeune utilisateur de boîte à lunch fournit aux intervenants une autre perspective selon laquelle étudier cette activité quotidienne et/ou élaborer des projets promotionnels en santé publique. / Objective. To improve the understanding of the eating behaviour of children, relative to lunch boxes, as described by their mothers and taking into consideration the contribution of Jean-Pierre Poulain’s six descriptors of human food behaviour. Methods. Individual and group interviews were conducted with 5 dietitians and 13 mothers. Qualitative analysis has been done using Poulain’s descriptors, on the eating behaviour of children and their lunch boxes. The material dimension of the lunch box was also considered. Results. Space dimension : Meals are eaten into classrooms or in large areas designed for that matter. Temporal dimension : The time and the duration of the activity varies, depending on different factors. Moment and time involve preparing the lunch box is also of interest. Social environment : Peers and media in general have an important influence on the behaviour of lunch baggers. Logic of choice : The mother is the key decision maker and actor with regards to the lunch box content. Content : Lunch can be related to last meals leftovers or home made sandwiches, side dishes and desserts are also of interest. Analysis of comments associated to the lunch box material dimension reveals the importance of ease of cleaning as a key factor for the mothers. Visuals appearance is the most important factor for the kids. Environment becomes a growing concern. Conclusion. This new way of looking at the food behaviour of young lunch box users may help public health educators to inform and assist the actors involve in this daily activity and/or develop public health promotion program.

Traditionally the machine learning community has viewed the No Free Lunch (NFL) theorems for search and optimization as a limitation. I review, analyze, and unify the NFL theorem with the many frameworks to arrive at necessary conditions for improving black-box optimization, model selection, and machine learning in general. I review meta-learning literature to determine when and how meta-learning can benefit machine learning. We generalize meta-learning, in context of the NFL theorems, to arrive at a novel technique called Anti-Training with Sacrificial Data (ATSD). My technique applies at the meta level to arrive at domain specific algorithms and models. I also show how to generate sacrificial data. An extensive case study is presented along with simulated annealing results to demonstrate the efficacy of the ATSD method.
