Student Achievement of Experiential Learning Objectives

Experiential learning is an important component of undergraduate hospitality programs, but most of the research in this area has focused on administrative and design issues. The author reports on a study undertaken to ascertain student perceptions as they relate to three commonly stated goals of experiential programs: the application of classroom studies, technical training, and management development

Wissensmanagementsysteme in Schulen oder: wie bringe ich Ordnung ins Chaos?

Die zunehmende Ausstattung von Schulen mit digitalen Medien wird zu einer Herausforderung für die Organisationsentwicklung. Digitale Materialien der Lehrkräfte sowie Schülerarbeiten in digitalisierter Form wachsen tagtäglich an. Bisher fehlen geeignete organisatorische und technische Möglichkeiten zur Archivierung, Verteilung und Nutzung. In Unternehmen hat sich mit dem Begriff Wissensmanagement ein organsatorisches Konzept etabliert, das die Nutzung der Ressource Wissen optimieren will. Um diese Prozesse zu unterstützen, wurden und werden informations- und kommunikationstechnische Werkzeuge entwickelt, deren Übertragung auf den Schulbereich aufgrund dessen organisatorischer Komplexität aber scheitern muss. In diesem Beitrag werden diese Besonderheiten herausgestellt und die Erfahrungen mit der Entwicklung eines webbasierten Wissensmanagementsystems in Zusammenarbeit mit Schulen skizziert

Depressive Cognitions In University Students: An Investigation Of Two Theories Of Depression

The purpose of this study was to examine concurrently the Beck and Seligman cognitive theories of depression. The study involved the testing of task perceptions, and self-referent perceptions more germane to the theories. The relevance of Bandura\u27s self-efficacy construct, to the understanding of depression, was also assessed. Further, issues pertaining to the assessment of depression and to the generalizability of experimental tasks were investigated.;The subjects in the study were undergraduate university women, who qualified for one of three subject groups. On the basis of the Beck Depression Inventory (BDI), a nondepressed (Normal) and depressed group (Severity) were formed. An additional depressed group (Clinical) was derived using both a severity criterion (BDI) and the Research Diagnostic Criteria.;The study involved a 3 (subject group) x 2 (task) factorial design. Half of the subjects from each group were assigned the Alloy and Abramson task, involving the problem of determining amount of control over the outcome. The other subjects received the Wener and Rehm task, in which they were to maximize their success. Regardless of the task condition, all subjects received experimenter-controlled feedback to only 20% of their responses.;The Clinically depressed group differed from the other two groups on most of the dependent measures relevant to Beck\u27s theory, but only on the measure of the central tenant of Seligman\u27s theory. Overall, the results of this study generally supported Beck\u27s cognitive theory but not Seligman\u27s learned helplessness theory of depression. Consideration was also given to the relevance of the concept of self-efficacy and of stress to depression, as well as the importance of subject selection criteria in depression research

Computing secular motion under slowly rotating quadratic perturbation

We consider secular perturbations of nearly Keplerian two-body motion under a perturbing potential that can be approximated to sufficient accuracy by expanding it to second order in the coordinates. After averaging over time to obtain the secular Hamiltonian, we use angular momentum and eccentricity vectors as elements. The method of variation of constants then leads to a set of equations of motion that are simple and regular, thus allowing efficient numerical integration. Some possible applications are briefly described.Comment: 3 pages, 0 figures accepted for publicatio
