The World Wide Web as an application platform becomes increasingly important. However, the development of Web applications is often more complex than for the desktop. Web-based development environments like Lively Webwerkstatt can mitigate this problem by making the development process more interactive and direct. By moving the development environment into the Web, applications can be developed collaboratively in a Wiki-like manner. This report documents the results of the project seminar on Web-based Development Environments 2010. In this seminar, participants extended the Web-based development environment Lively Webwerkstatt. They worked in small teams on current research topics from the field of Web-development and tool support for programmers and implemented their results in the Webwerkstatt environment.
In current practice, business processes modeling is done by trained method experts. Domain experts are interviewed to elicit their process information but not involved in modeling. We created a haptic toolkit for process modeling that can be used in process elicitation sessions with domain experts. We hypothesize that this leads to more effective process elicitation. This paper brakes down "effective elicitation" to 14 operationalized hypotheses. They are assessed in a controlled experiment using questionnaires, process model feedback tests and video analysis. The experiment compares our approach to structured interviews in a repeated measurement design. We executed the experiment with 17 student clerks from a trade school. They represent potential users of the tool. Six out of fourteen hypotheses showed significant difference due to the method applied. Subjects reported more fun and more insights into process modeling with tangible media. Video analysis showed significantly more reviews and corrections applied during process elicitation. Moreover, people take more time to talk and think about their processes. We conclude that tangible media creates a different working mode for people in process elicitation with fun, new insights and instant feedback on preliminary results.
IT systems for healthcare are a complex and exciting field. One the one hand, there is a vast number of improvements and work alleviations that computers can bring to everyday healthcare. Some ways of treatment, diagnoses and organisational tasks were even made possible by computer usage in the first place. On the other hand, there are many factors that encumber computer usage and make development of IT systems for healthcare a challenging, sometimes even frustrating task. These factors are not solely technology-related, but just as well social or economical conditions. This report describes some of the idiosyncrasies of IT systems in the healthcare domain, with a special focus on legal regulations, standards and security.
Business process models are abstractions of concrete operational procedures that occur in the daily business of organizations. To cope with the complexity of these models, business process model abstraction has been introduced recently. Its goal is to derive from a detailed process model several abstract models that provide a high-level understanding of the process. While techniques for constructing abstract models are reported in the literature, little is known about the relationships between process instances and abstract models. In this paper we show how the state of an abstract activity can be calculated from the states of related, detailed process activities as they happen. The approach uses activity state propagation. With state uniqueness and state transition correctness we introduce formal properties that improve the understanding of state propagation. Algorithms to check these properties are devised. Finally, we use behavioral profiles to identify and classify behavioral inconsistencies in abstract process models that might occur, once activity state propagation is used.
This is the 15th issue of the working paper series Interdisciplinary Studies on Information Structure (ISIS) of the Sonderforschungsbereich (SFB) 632. This online version contains the Questionnaire on Focus Semantics contributed by Agata Renans, Malte Zimmermann and Markus Greif, members of Project D2 investigating information structural phenomena from a typological perspective. The present issue provides a tool for collecting and analyzing natural data with respect to relevant linguistic questions concerning focus types, focus sensitive particles, and the effects of quantificational adverbs and presupposition on focus semantics. This volume is a supplementation to the Reference manual of the Questionnaire on Information Structure, issued by Project D2 in ISIS 4 (2006).
In Kooperation mit Partnern aus der Industrie etabliert das Hasso-Plattner-Institut (HPI) ein “HPI Future SOC Lab”, das eine komplette Infrastruktur von hochkomplexen on-demand Systemen auf neuester, am Markt noch nicht verfügbarer, massiv paralleler (multi-/many-core) Hardware mit enormen Hauptspeicherkapazitäten und dafür konzipierte Software bereitstellt. Das HPI Future SOC Lab verfügt über prototypische 4- und 8-way Intel 64-Bit Serversysteme von Fujitsu und Hewlett-Packard mit 32- bzw. 64-Cores und 1 - 2 TB Hauptspeicher. Es kommen weiterhin hochperformante Speichersysteme von EMC² sowie Virtualisierungslösungen von VMware zum Einsatz. SAP stellt ihre neueste Business by Design (ByD) Software zur Verfügung und auch komplexe reale Unternehmensdaten stehen zur Verfügung, auf die für Forschungszwecke zugegriffen werden kann. Interessierte Wissenschaftler aus universitären und außeruniversitären Forschungsinstitutionen können im HPI Future SOC Lab zukünftige hoch-komplexe IT-Systeme untersuchen, neue Ideen / Datenstrukturen / Algorithmen entwickeln und bis hin zur praktischen Erprobung verfolgen. Dieser Technische Bericht stellt erste Ergebnisse der im Rahmen der Eröffnung des Future SOC Labs im Juni 2010 gestarteten Forschungsprojekte vor. Ausgewählte Projekte stellten ihre Ergebnisse am 27. Oktober 2010 im Rahmen der Future SOC Lab Tag Veranstaltung vor.
New Public Management
(2011)
New Public Management hat in den vergangenen Jahren die Ansätze und das Verständnis moderner Verwaltungsführung maßgebend beeinflusst.
Stossrichtungen und Grundanliegen dieses Modells wurden zum Teil in die Führungspraxis übernommen und stellen in vielerlei Hinsicht nach wie vor Entwicklungsziele und Leitlinien für die Steuerung und Führung der öffentlichen Verwaltung dar. NPM soll die öffentliche Verwaltung an geforderte Neuausrichtungen anpassen und effizienter gestalten. Ziele und Gestaltung der öffentlichen Verwaltung unter NPM und die dazu notwendigen Instrumente werden in diesem Lehrbuch umfassend und strukturiert erläutert. Besonderes Augenmerk wird dabei auf die Veränderungslinien und -ansätze für die Verwaltungsführung gelegt.
This is the 16th issue of the working paper series Interdisciplinary Studies on Information Structure (ISIS) of the Sonderforschungsbereich (SFB) 632. The present issue continues the series on Linguistic Fieldnotes providing data elicited and documented by different members of the Sonderforschungsbereich 632. Here, the focus is placed on primary linguistic data from Gur and Kwa languages, collected and prepared by Anne Schwarz, former investigator in Project B1 and D2, and Ines Fiedler, former investigator in Project B1 and D2 and current member of Project B7 at Humboldt-Universität zu Berlin.
