An Approach to Meeting AACSB Assurance of Learning Standards in an IS Core Course

AACSB accreditation is a much sought designation by business schools in the United States, and increasingly, around the world. Beginning in 2003, AACSB changed its focus on the business curriculum from an assessment of inputs to an assessment of outputs. This change has greatly increased the demands on faculty because programs must now demonstrate learning outcomes, not just what students are taught. The purpose of this paper is to present an efficient and effective method to assess learning outcomes in an IS core (required) course in the undergraduate program, by seeing how an accredited mid-western state university developed and implemented a course to meet the new AACSB requirements. We describe the process used to assess learning outcomes and how the results of the assessment are used to improve learning outcomes. We also describe how the IS course assessment ties in to learning assessment of the undergraduate program as a whole

Logics for Unranked Trees: An Overview

Labeled unranked trees are used as a model of XML documents, and logical languages for them have been studied actively over the past several years. Such logics have different purposes: some are better suited for extracting data, some for expressing navigational properties, and some make it easy to relate complex properties of trees to the existence of tree automata for those properties. Furthermore, logics differ significantly in their model-checking properties, their automata models, and their behavior on ordered and unordered trees. In this paper we present a survey of logics for unranked trees

Stability of string defects in models of non-Abelian symmetry breaking

In this paper we describe a new type of topological defect, called a homilia string, which is stabilized via interactions with the string network. Using analytical and numerical techniques, we investigate the stability and dynamics of homilia strings, and show that they can form stable electroweak strings. In SU(2)xU(1) models of symmetry breaking the intersection of two homilia strings is identified with a sphaleron. Due to repulsive forces, the homilia strings seperate, resulting in sphaleron annihilation. It is shown that electroweak homilia string loops cannot stabilize as vortons, which circumvents the adverse cosmological problems associated with stable loops. The consequences for GUT scale homilia strings are also discussed.Comment: 15 pages, revtex, with 8 figures. Submitted to PR
