Then, technological security aspects are derived due to democratic basic principles. Especially the applied voting procedures are critical in security terms. Hence, the most relevant cryptographic protocols are presented and their drawbacks and shortcomings are identified. However, this article does not propose a new voting protocol. Beyond fixing cryptographic procedures for ballots, more elements are to be specified, e.g. responsibilities and rights of involved authorities or security precautions regarding hardware and software. For this reason, a structural security framework for electronic voting systems is presented which can be used for their composition and analysis.}}, author = {{Schryen, Guido}}, booktitle = {{37th Annual Hawaii International Conference on System Sciences}}, title = {{{Security Aspects of Internet Voting}}}, year = {{2004}}, } @book{6143, author = {{Kabst, Rüdiger}}, isbn = {{978-3879888443}}, title = {{{Internationalisierung mittelständischer Unternehmen: Fünf Thesen zum Auslandsmarkterfolg}}}, year = {{2004}}, } @inbook{6215, author = {{Kabst, Rüdiger and Brewster, C}}, booktitle = {{Handwörterbuch des Personalwesens}}, editor = {{Gaugler, E and Oechsler, W A and Weber, W}}, pages = {{937--944}}, title = {{{International komparatives Personalmanagement: Evidenz, Methodik & Klassiker des "Cranfield Projects on International Human Resource Management"}}}, year = {{2004}}, } @inbook{6216, author = {{Dietz, B and Hoogendoorn, J and Kabst, Rüdiger and Schmelter, A}}, booktitle = {{Human Resource Management in Europe: Evidence of Convergence?}}, editor = {{Brewster, C and Mayrhofer, W and Moley, M}}, pages = {{73--94}}, title = {{{The Netherlands and Germany: Flexibility or Rigidity}}}, year = {{2004}}, } @inbook{6217, author = {{Kabst, Rüdiger}}, booktitle = {{Personaltheorie als Beitrag zur Theorie der Unternehmung}}, editor = {{Festing, M and Martin, A and Mayrhofer, W and Nienhüser, W}}, pages = {{43--70}}, title = {{{Transaktionskostentheorie: Einführung, kritische Diskussion und Ansätze zur Weiterentwicklung}}}, year = {{2004}}, } @article{6233, author = {{Kabst, Rüdiger and Weber, W}}, journal = {{Management Revue: The International Review of Management Studies.}}, number = {{2}}, title = {{{Theoretical Perspectives for Human Resource Management: The German Discussion}}}, volume = {{15}}, year = {{2004}}, } @article{4615, author = {{Feng, Yuanhua}}, issn = {{0266-4666}}, journal = {{Econometric Theory}}, number = {{03}}, publisher = {{Cambridge University Press (CUP)}}, title = {{{SIMULTANEOUSLY MODELING CONDITIONAL HETEROSKEDASTICITY AND SCALE CHANGE}}}, doi = {{10.1017/s0266466604203061}}, volume = {{20}}, year = {{2004}}, } @book{4630, author = {{Feng, Yuanhua}}, title = {{{Non- and Semiparametric Regression with Fractional Time Series Errors}}}, year = {{2004}}, } @inbook{4634, author = {{Heiler, Siegfried and Feng, Yuanhua}}, booktitle = {{Zeitreihenanalyse in der empirischen Wirtschaftsforschung}}, editor = {{Metz, Rainer and Lösch, Manfred and Edel, Klaus}}, pages = {{67 -- 81}}, publisher = {{Lucius & Lucius}}, title = {{{A robust data-driven version of the Berlin Method}}}, year = {{2004}}, } @article{4830, author = {{Paunescu, Mihai and Schneider, Martin}}, journal = {{Schmollers Jahrbuch: Journal of Applied Social Science Studies/Zeitschrift für Wirtschafts-und Sozialwissenschaften}}, number = {{1}}, pages = {{31----59}}, title = {{{Wettbewerbsfähigkeit und Dynamik institutioneller Standortbedingungen: Ein empirischer Test des „Varieties-of-Capitalism “-Ansatzes}}}, year = {{2004}}, } @article{4891, author = {{Fahr, Rene and Sunde, Uwe}}, journal = {{Oxford Economic Papers}}, number = {{3}}, pages = {{407----435}}, title = {{{Occupational job creation: patterns and implications}}}, year = {{2004}}, } @techreport{4900, author = {{Toshihiro, KODAMA and Yoshio, HIGUCHI and Masahiro, ABE and Fahr, Rene}}, title = {{{A Comparative Analysis of Job Entry Methods in Japan, the US and Europe (Japanese)}}}, year = {{2004}}, } @inbook{4907, author = {{Fahr, Rene}}, booktitle = {{The Economics of Time Use}}, pages = {{175----203}}, title = {{{Loafing or Learning?}}}, year = {{2004}}, } @article{4923, author = {{Paunescu, Mihai and Schneider, Martin}}, journal = {{Schmollers Jahrbuch: Journal of Applied Social Science Studies/Zeitschrift f{\"u}r Wirtschafts-und Sozialwissenschaften}}, number = {{1}}, pages = {{31----59}}, title = {{{Wettbewerbsf{\"a}higkeit und Dynamik institutioneller Standortbedingungen: Ein empirischer Test des „Varieties-of-Capitalism “-Ansatzes}}}, year = {{2004}}, } @misc{4925, author = {{Eggert, A}}, title = {{{Wertorientiertes Beziehungsmarketing in Kunden-Lieferantenbeziehungen.}}}, year = {{2004}}, } @article{4927, author = {{Bliemel, Friedhelm and Eggert, Andreas and Fassott, Georg and Ballantyne, David}}, issn = {{1533-2667}}, journal = {{Journal of Relationship Marketing}}, number = {{4}}, pages = {{1--5}}, publisher = {{Informa UK Limited}}, title = {{{The Evolution of Relationship Marketing and the International Colloquia}}}, doi = {{10.1300/j366v03n04_01}}, volume = {{3}}, year = {{2004}}, } @article{7382, abstract = {{UML offers different diagram types to model behavior and dynamics of software systems.

These entities are named software agents. More and more software systems are distributed, dynamic and open with respect to their environment. Software agents shall ease the development of such systems. Agent based systems provide a modular structure. They are robust and can be adapted dynamically to changing requirements. The notion of software agent relies on the fundamental properties of autonomy, proactivity and structured interaction. According to these properties agents are distinguished from objects and components. For the development of agent based systems an appropriate modeling language and a process model describing the correct usage of the language are demanded. For both aspects only unsufficient or incomplete approaches exist. This thesis contributes to the solution in the following way: A new abstract and formal model of agent based systems shows, that the fundamental properties can be expressed precisely. Differently from existing models not only a single agent but a multi agent system can be modeled. The most important architectural models of agent-based systems are compatible with the abstract model. The rather restricted structure of the abstract model motivates the refinement by a model of coupled I/Oautomata. The Unified Modeling Language is widely used in industrial software development. Therefore, the new language AML (Agent Modeling Language) for the development of agent-based systems is defined as a UML profile. The semantics of AML models is defined in the semantic domain of graph transformation. The semantic domain is restricted to an adequate agent-oriented domain. There the constituents of the fundamental agent properties are defined. Agent based systems which are described using AML are shown to be compatible with I/O-automata model of multi agent systems. Constituents for proactivity are goals and strategies. In this thesis, it is shown that the reachability of goals through the application of strategies can be checked by applying a model checking method. The new process model APM describes, how the language AML can be applied to the modeling of agent-based systems.}}, author = {{Depke, Ralph}}, title = {{{Visuelle Modellierung agentenbasierter Systeme}}}, year = {{2004}}, } @article{7678, author = {{Haberer, E.

Diese mikroskopische Beschreibung wird durch Kombination eines allgemeinen Dichtematrixansatzes mit speziellen Methoden zur Auswertung der Maxwellgleichungen wie der zeitaufgelösten Finite-Differenzen-Methode (FDTD) erreicht. Die Theorie wird auf verschiedene physikalische Situationen angewendet, wie z.B. Lichtausbreitung in Volumenhalbleitern, Interband- und Intersubbandübergänge in Quantenfilmstrukturen und optische Anregung von Quantenpunkten. Der Fokus liegt dabei auf der Beschreibung der linearen und nichtlinearen Antwort des Vielteilchensystems und seiner Ankopplung an das elektromagnetische Feld. In diesem Zusammenhang wird sowohl die Erzeugung als auch der Zerfall von optischen Anregungen untersucht, indem verschiedene Kopplungsmechanismen wie Elektron-Phonon-, Elektron-Photon- und Elektron-Elektron-Wechselwirkung berücksichtigt werden. Im Bereich der linearen Optik, also für Anregung mit geringer Intensität, ermöglicht die Theorie die Berechnung von Absorptionsspektren. Verschiedene Effekte in linearer Optik werden in dieser Arbeit untersucht und beschrieben: Linienaufspaltung durch Polaritonen im Volumenmaterial, Zunahme der Linienbreite bei Intersubbandübergängen verursacht durch Elektron-Elektron- und Elektron- Phonon-Streuung in einzelnen Quantenfilmen, Bildung einer optischen Bandlücke durch starke radiative Kopplung in Vielfilmstrukturen in Bragg-Geometrie, Phononenseitenbänder verursacht durch quantenkinetische Effekte in einzelnen Quantenpunkten und schliesslich Superradianz und Interferenzeffekte in Quantenpunktgittern. Bei nichtlinearer Anregung treten Dichte-Rabiflops als fundamentale Prozesse in allen betrachteten Systemen auf und können als kohärente Be- und Entvölkerung von quantenmechanischen Zuständen beobachtet werden. Der Einfluss von starker Lichtkopplung und verschiedenen Wechselwirkungen auf dynamische Größen wie die Besetzung wird untersucht. Bei nichtlinearer Propagation, bei der sich ein starker Lichtpuls über längere Strecken in einem System bewegt, wird selbstinduzierte Verstärkung der Transmission näher betrachtet. Des weiteren werden von der Coulombwechselwirkung verursachte nichtlineare Effekte wie exzitoninduziertes Dephasieren in Volumenmaterial und verschränkte Zustände in Quantenpunkten untersucht, die einen Zusammenbruch der Hartree-Fock- Näherung darstellen.
