Kooperation von Projekt- und Workflow-Management-Systemen

Zusammenfassung. Während Projekt-Management-Systeme zur Planung fast jedes Projekts eingesetzt werden, gewinnen Workflow-Management-Systeme für die Realisierung von prozessorientierten Anwendungen zunehmend an Bedeutung. Da sich beide Systemarten um das Management von Abläufen kümmern, ist eine Kooperation entsprechender Systeme für die Praxis sehr relevant. In diesem Beitrag stellen wir die einschlägigen wissenschaftlichen und kommerziellen Ansätze vor und untersuchen sie ausführlich. Da diese nur über eine unzureichende Funktionalität verfügen, entwickeln wir anschließend Architekturen, die ein besseres Zusammenspiel der beiden Systemarten erlauben. Dabei gehen wir auch auf den in der Literatur bisher nicht betrachteten Fall ein, dass die Projektplanung auf einem höheren Abstraktionsniveau erfolgt als die Modellierung und Ausführung der Workflows. Wir zeigen für diesen in der Praxis häufig anzutreffenden Fall auf, wie eine Kooperation der beiden Systemarten mit einer auf Event-Condition-Action-Rules basierenden generischen Kopplungsarchitektur realisiert werden kann.CR Subject Classification: K.6.1, H.4.1Eingegangen am 9.

Identity and Culture: theorising emergent environmentalism

This article critically examines the methodology and findings of the emergent environmentalism research project as reported in Environmental Education Research (EER), 4(4). We challenge both the ontological stance implicit in the research as well as its explicit epistemology. We argue for a wider theoretical underpinning to the research and specifically advocate the use of identity theories to explain personal and social phenomena. We also argue for the use of theoretical frameworks that empower rather than ‘capture’ cultural groups.     

Randomized interdependent group contingencies: Group reinforcement with a twist

This investigation examined the effects of randomizing components of an interdependent group contingency procedure on the target behavior of 12 students in a second‐grade classroom in a rural southeastern school district. Specifically, using a multiphase time‐series design (i.e., A‐B‐A‐C‐B‐C design) levels of disruptive behavior were compared across baseline, an intervention phase with only randomized reinforcers (the RR+ phase), and an intervention phase with all components randomized (R‐ALL phase). Results suggest that both interventions were successful in decreasing levels of disruptive behavior, with the R‐ALL phase resulting in lower mean, and more stable, percentages of disruptive behavior. The advantages to randomizing components within a group contingency procedure are discussed, because this procedure not only incorporates the strengths of an interdependent group contingency, but also addresses the limitations. © 2000 John Wiley & Sons, Inc.     

Effect on development of proportional reasoning skill of physical experience and cognitive abilities associated with prefrontal lobe activity

The present study tested the hypothesis that maturing prefrontal lobes play a role in the development of proportional reasoning skill because the prefrontal lobes are involved in the inhibition of task‐irrelevant information and the representation of task‐relevant information. The hypothesis that reasoning development is in part dependent upon physical experience was also tested. Students (all males) who failed to solve a diagnostic proportions task were administered several tests of prefrontal lobe functions. The students were then randomly assigned to manipulative or verbal tutoring groups. Both groups received a series of individual testing, tutoring and testing sessions on proportional reasoning. As predicted, performance on the prefrontal lobe tasks (measures of inhibiting ability, planning ability, dissembedding ability, and working memory capacity) significantly predicted performance on proportional reasoning tasks following tutoring. Students' computational skills were not a significant predictor. Also, the manipulative group's proportional reasoning performance was significantly higher than that of the verbal tutoring group. Therefore, the present results provide support for the hypothesis that maturing prefrontal lobes and physical experience play roles in the development of proportional reasoning skill. © 2000 John Wiley & Sons, Inc.
