We would like to welcome you to the proceedings of the workshops held in c- junction with the 27th International Conference on Conceptual Modeling (ER 2008). While the ER main conference covers a wide spectrum of conceptual modeling research, increasingly complex real-world problems demand new p- spectives and activeresearchin new applications.The ER workshopsattempt to provideresearchers, students, andindustry professionalswitha forumto present and discuss emerging hot topics related to conceptual modeling. We received 13 excellent proposals for workshops to be held with ER 2008. We accepted the following seven based on peer reviews: 1. The Second International Workshop on Conceptual Modeling for Life S- ences Applications (CMLSA 2008), organized by Yi-Ping Phoebe Chen and Sven Hartmann. 2. The 5th International Workshopon Evolution and Change in Data Mana- ment (ECDM 2008), organized by Fabio Grandi. 3. The 4th International Workshop on Foundations and Practices of UML (FP-UML 2008), organized by Juan Trujillo and Andreas L. Opdahl. 4. The First International Workshop on Modeling Mobile Applications and Services (M2AS 2008), organized by Fernando Ferri, Patrizia Grifoni, and Maria Chiara Caschera. 5. The Second International Workshop on Requirements, Intentions and Goals in Conceptual Modeling (RIGiM 2008), organized by Colette Rolland, C- son Woo, and Camille Salinesi. 6. The Second International Workshop on Semantic and Conceptual Issues in Geographic Information Systems (SeCoGIS 2008), organized by Esteban Zim anyi and Christophe Claramunt. 7. The 5th International Workshop on Web Information Systems Modeling (WISM 2008), organized by Flavius Frasincar, Geert-Jan Houben, and Philippe Thiran."

The InternationalConferenceonWeb InformationSystems Engineering(WISE) providesanannualforumforexploringresearch, development, novelapplications and industrial innovations in the area of Web Information Systems. The 9th edition ofthis conference(WISE 2008)washeld in Auckland, NewZealandfrom September 1 to 3, 2008. This volume contains the papers that were presented during the WISE 2008 workshops. We commend these papers to you and hope you ?nd them useful. A major objective of the WISE conferences is to identify new issues and directions in Web engineering, to share experiences, to host discussions, and to initiate future workandcollaborations. Associatedworkshopsdevotedto eme- ing or specialist topics are an important part of the WISE conferences helping to make them an inspiring experience for all participants. Three workshopswere organized and held in conjunction with the WISE 2008 main conference: - The First International Workshop on Web Information Systems Engine- ing for Electronic Businesses and Governments (E-BAG 2008), chaired by Sebastian Link (Victoria University of Wellington, New Zealand), Hui Ma (VictoriaUniversityofWellington, NewZealand), andJianYang(Macquarie University, Sydney, Australia); - The Second International Workshop on Web Usability and Accessibility (IWWUA 2008), chaired by Silvia Abrahao (Valencia University of Techn- ogy, Spain), Cristina Cachero(University ofAlicante, Spain), and Maristella Matera (Politecnico di Milano, Italy); and - The First International Workshop on Mashups, Enterprise Mashups and LightweightCompositionontheWeb(MEM&LCW2008), chairedbyMarek Kowalkiewicz(SAP ResearchBrisbane, Australia), Dominik Flejter (Poznan University of Economics, Poland), and Tomasz Kaczmarek (Poznan Univ- sity of Economics, Poland). Following calls for papers, we received 40 submissions

The 13 revised full papers presented together with 9 revised short papers and 3 invited lectures were carefully selected during two rounds of reviewing and improvement from from 79 submissions. The papers deal with any foundational aspect of information and knowledge systems, including submissions from researchers working in fields such as discrete mathematics, logic and algebra, model theory, information theory, complexity theory, algorithmics and computation, geometry, analysis, statistics and optimisation who are interested in applying their ideas, theories and methods to research on information and knowledge systems.

This book constitutes the refereed joint proceedings of six international workshops held in conjunction with the 26th International Conference on Conceptual Modeling, ER 2007, in Auckland, New Zealand, in November 2007.

The 40 revised full papers presented were carefully reviewed and selected from 114 submissions. Topics addressed by the workshops are conceptual modeling for life sciences applications (CMLSA 2007), foundations and practices of UML (FP-UML 2007), ontologies and information systems for the semantic Web (ONISW 2007), quality of information systems (QoIS 2007), requirements, intentions and goals in conceptual modeling (RIGiM 2007), and semantic and conceptual issues in geographic information systems (SeCoGIS 2007).

Der Mensch neigt zunehmend dazu, Systeme und Strukturen immer effizienter zu gestalten. Dass dieses Effizienzstreben in letzter Instanz eigentlich auf dem Rucken des einzelnen Mitarbeiters ausgetragen wird, geriet dabei zusehends in Vergessenheit. Damit Organisationen auch nachhaltig Erfolge verbuchen konnen, bedarf es mehr Robustheit und Belastbarkeit. Was Albert Einstein schon erkannte - namlich dass Probleme nur mit anderen Denkweisen gelost werden konnen, als diejenigen, die sie verursacht haben - muss haufiger gangige Praxis in Organisationen jeglicher Art werden Es braucht mehr Vielfalt, eine hohere Bereitschaft zum proaktiven Leben einer Dialogdiskurskultur sowie insgesamt mehr Akzeptanz (vgl. entwickelte Checkliste im Abschnitt 4.3 dieser Arbeit). Diese BA-Arbeit soll mit Hilfe von ausgewahlten, fuhrungsrelevanten Erkenntnissen des Neurobiologen Gerald Huther der Fuhrungskraft Handlungsempfehlungen zur Losung des von Lietaer aufgezeigten Effizienzproblems liefern. Darin besteht auch ihre Legitimation. Diese Handlungsempfehlungen sollen der Fuhrungskraft in Form einer Checkliste wieder den Weg hin zu einem Vitalitatsfester ermoglichen. Es soll Abstand von dem klassischen effizienztreibenden Fuhrungsverstandnis genommen und stattdessen eines entwickelt werden, das den Weg zu mehr Robustheit und demzufolge auch Nachhaltigkeit in einer Organisation ebnet. Unterstutzend wird das Ziel verfolgt, im Rahmen einer umfassenden Grafik fur die Fuhrungskraft die aus den neurobiologischen Erkenntnissen resultierenden Implikationen so transparent wie moglich abzubilden. Dargestellt in einem Totalmodell sowie aufbereitet in einer Checkliste wird der Versuch unternommen, die notwendigen Zusammenhange und Verhaltensempfehlungen fur eine Fuhrungskraft am Ende der Arbeit aufzuzeigen.

Masterarbeit aus dem Jahr 2011 im Fachbereich BWL - Unternehmensfuhrung, Management, Organisation, Note: 2,0, Universitat der Bundeswehr Munchen, Neubiberg (Internationales Management), Veranstaltung: Entwicklung zukunftsfahiger Organisationen, Sprache: Deutsch, Abstract: Fuhrung ist ein Begriff, der sich subjektiver Beobachtungen und Eindrucken zufolge in unserer Gesellschaft sehr weit verbreitet ist und vielfaltig verstanden wird. Es gibt diverse Differenzierungen und Formen sowie Logiken und Stile. Im Zuge des Praxisbeispiels einer sudbrasilianischen Grossstadt sollte sich mit dem bislang wenig beleuchteten Spannungsfeld von individueller und kollektiver Fuhrung befasst werden. Das in der BA-Arbeit beschriebene Effizienzstreben von Menschen i. S. von Lietaer aussert sich in diesem Kontext haufig durch individuelle Fuhrung. Dennoch mag die Logik von Fuhrung in einem eher harmonischen bzw. ausgewogenen Verhaltnis beider Pole liegen. Curitiba hat uber viele Jahrzehnte Erfolg produziert...auch lange nach den Amtszeiten Lerners - charakterisiert durch konsequente, straffe individuelle Fuhrung - aussert sich die damals gepflanzte Saat uber einen kollektiven Prozess von Burgern und Stakeholder Curitibas als Kultur des Respekts und der Wertschatzung. Es bleibt wohl auf den Punkt zu bringen, dass das Spannungsfeld in wirtschaftlichen Organisationen jeglicher Art durchaus erfolgreich Bestand haben kann: Its possible. Letztlich habe ich mir in meiner MA-Arbeit folgende Zielsetzung gesetzt: * wertvolle Implikationen aus dem Erfolgsbeispiel der sud-brasilianischen Metropole Curitiba fur das Management herauszuarbeiten. Unter Berucksichtigung theoretischer sowie praktischer Grundlagen sollen daraus unmittelbar abgeleitete Lehren fur Manager und Fuhrungskrafte gezogen werden. * Curitiba anhand operativer Erfolgserlebnisse und -beispiele im Spannungsfeld zwischen individueller und kollektiver Fuhrung zu verorten und zu bewerten. Das modifizierte Modell von LIETAER soll
