In this paper cores and stable sets for games with fuzzy coalitions are introduced and their relations studied. For convex fuzzy games it turns out that all cores coincide and that the core is the unique stable set. Also relations between cores and stable sets for fuzzy clan games are discussed.

The MIS data is critical to an organization and should be protected from misuse by wrong persons. Although The MIS data is typically meant for the senior managers each MIS report may not be required by every manager. The access to MIS data is determined by the role of an individual in the organization and controlled by the MIS administrator accordingly. The access is generally determined by the...

We prove that there is an absolute constant C > 0 so that for every natural n there exists a trianglefree regular graph with no independent set of size at least C √ n log n.

The question of the relevance of MIS research to practitioners is part of the broader question of the match between academic research goals and the goals of constituents. We call for a broader conception of who those constituents might be, and the implications that has for the activities of MIS academics.

We show that a graph with minimum degree δ, independence number α ≥ δ and without isolated vertices, possesses a partition by vertex-disjoint cycles and atmost α−δ+1 edges or vertices. © 2008 Elsevier B.V. All rights reserved.

Flipped classroom is one approach of active learning leading to better students’ learning, abilities, and academic performance. The aim of this study is to evaluate the effect of applying the flipped classroom approach to MIS course, to examine the antecedents of engagement intention after participating the flipped classroom by peers, and to guide key factors of success student presentations. T...

This article reports the results of an experimental analysis of the impact of MIS design variables on managers" evaluations of subordinates" performances. The experiment involved examining whether different ways of reporting a specific standard cost accounting situation resulted in differences in managers’ evaluations. When actual costs differed significantly from standard, it was found that th...

The goal of this paper is to find vertex disjoint even cycles in graphs. For this purpose, define a θ-graph to be a pair of vertices u, v with three internally disjoint paths joining u to v. Given an independence number α and a fixed integer k, the results contained in this paper provide sharp bounds on the order f(k, α) of a graph with independence number α(G) ≤ α which contains no k disjoint ...

An asteroidal triple is an independent set of three vertices in a graph such that every two of them are joined by a path avoiding the closed neighborhood of the third. Graphs without asteroidal triples are called AT-free graphs. In this paper, we show that every AT-free graph admits a vertex ordering that we call a 2-cocomparability ordering. The new suggested ordering generalizes the cocompara...

Web-based learning has been suggested to be the future of all types of distance learning. This study was undertaken to identify the impact of student learning styles, learning patterns, and other selected factors on their learning performance in a Web Course Tools (WebCT) MIS graduate course. Six specific research questions were developed and 76 graduate students participated in this study. It ...
