In line with the goals of this thesis, it will address the following research questions: - How did Internet voting originate? - What experiences were noted in the process of implementing Internet voting in Austria? - What building blocks can be identified for developing future Internet voting both...

  2. Images of prison: Managing institutional complexity in the Austrian penal system

    Winter, Johanna
    Prisons are a specific type of organization with distinct challenges for their management. Most importantly, prisons - as well as understandings of how to 'successfully' manage them - are embedded in a pluralistic environment that consists of a variety of stakeholders with different ideas and expectations with regard to role and governance of prisons. This study addresses the question of which different understandings of 'good' prison management can be found in the Austrian discourse and how the expected complexity constituted by contradictory expectations is manifested in the shared narratives of prison managers. I draw on an institutional theory perspective in...

  3. Empirical Essays on Austrian Housing Policy Evaluation

    Mundt, Alexis
    This dissertation focuses on Austrian housing policy measures and regional housing markets. It places the Austrian situation into a European context and evaluates singular housing policy measures in detail. The evaluation includes aspects of effectiveness, equity, costs, and efficiency. This contribution brings together three empirical essays, each of which has a different focus and addresses particular elements of housing policy. All three papers use empirical methods, but with adjusted approaches according to their underlining research questions: from state finance comparisons, to subsidy calculations for specific households, to hedonic apartment price index construction. Quantitative methods, mainly based on administrative and survey...

  4. A knowledge perspective on needs to enhance organizational learning

    Kragulj, Florian
    Organizational learning causes organizational change. Different descriptive models have been proposed, but little research on variables influencing these processes has been done. Needs govern our behavior and motivate our acting. It has been shown that their identification and satisfaction effect value-creating and knowledge-intensive activities, such as innovation processes, strategy development, and product design. However, needs are usually implicitly anchored in organizations and people can hardly articulate them. Despite the fact that a focus on needs does not prescribe any concrete strategy, but extends opportunities to act, an initial consideration of needs often lacks. Consequently, their role as an influencing variable...

  5. Evaluations, Actors and Institutions. The Case of Research, Technology and Innovation Policy in Austria

    Streicher, Jürgen
    Evaluations have gained popularity for improving public policy measures, programmes and institutions in the field of science, technology and innovation (RTI). Though the frequency and quality of evaluations have increased, in terms of impact indicators and methodological diversification, concerns have been raised about their effectiveness to fuel change in policy making. This raises the issue of the low absorption level of evaluation findings by policy making in general and in Austria in particular. Recent research emphasises the need for a holistic perspective on the benefits and usefulness of evaluations in order to allow a more thorough consideration of complex interdependencies and...

  7. M&A in the public sector. Cultural dimensions of integration in a domestic merger.

    Schroll, Iris
    Since the late 1980s in most European countries the public sector has been characterized by ongoing privatization/liberalization strategies. Challenges related to this development are the merging of public institutions or units, the (re)creation of efficient processes, the increase in revenues, and the balancing between public service obligation and private sector competition. Approaching a case of a large Austrian company in the public health sector with a mixed methods design (narrative interviews, surveys), three major changes could be identified: a) breaking the bottleneck - development of processes, tools and awareness, b) reduction and regulation - ongoing business integration, and c) the good,...

  8. Manifestationen von Verwaltungsparadigmen in den Reformen des österreichischen Bundeshaushaltsgesetzes

    Polzer, Tobias
    Öffentliche Verwaltungen sind ständig Reformen unterworfen. Auch das öffentliche Haushaltsrecht in Österreich, obwohl tendenziell weniger anfällig für kurzlebige Reformen, wurde in den letzten drei Jahrzehnten umfassend novelliert. Auf globaler Ebene lassen sich in der Literatur für die vergangenen Dekaden drei dominierende "Verwaltungs-" bzw. "Reformparadigmen" identifizieren, die Orientierung für Reformen im öffentlichen Sektor bildeten bzw. bilden und sich aus in einer Zeitperiode gehäuft diskutierten Ideen zur Verwaltungmodernisierung herauskristallisierten: Public Administration, New Public Management und Public Governance. Aufbauend auf die neo-institutionalistische Organisationstheorie geht diese Dissertation der Frage nach, wie sich diese Paradigmen in den Reformen des österreichischen Bundeshaushaltsgesetzes der letzten 30 Jahre...

  9. Zwingendes Recht im Vertragsrecht: Eine allgemeine und rechtsökonomische Untersuchung unter besonderer Berücksichtigung der Sachmängelgewährleistung

    Tiefenbacher, Guenter
    Die vorliegende Arbeit beschäftigt sich mit der Suche nach möglichen Rechtfertigungen für zwingende Bestimmungen im Privatrecht. Da das Privatrecht stark vom Prinzip der Privatautonomie geprägt ist, werfen zwingende Bestimmungen die grundsätzliche Frage auf, ob diese wirklich notwendig sind. In der Arbeit wird gezeigt, dass zwingende Bestimmungen anhand verschiedener rechtsökonomischer Beurteilungsmaßstäbe analysiert werden können. So kann eine zwingend ausgestaltete Sachmängelgewährleistung (§§ 922 bis 933 ABGB), welche § 9 KSchG für Verbrauchergeschäfte festlegt, die Möglichkeiten des Übergebers einschränken auf seine gute Leistungsqualität hinzuweisen (Signalling). Dies könnte eine unerwünschte negative Selektion und somit Ineffizienzen am Markt zur Folge haben. Die Arbeit verbindet den...

  10. A Language for Designing Process Maps

    Malinova, Monika
    Business Process Management (BPM) is often adopted by organizations as a method to increase awareness and knowledge of their business processes. Business process modeling is used as a method to represent business processes in form of business process models. The number of organizations adopting BPM is quickly increasing. By this means, so is the number of business process models as result of a BPM initiative. Within a single organization the number of business process models often ranges from hundreds to even thousands. In order to handle such large amount of business process models, organizations structure them by the help of...

  11. Organizing Future: An Integrated Framework for the Emergence of Collective Self-transcending Knowledge

    Feldhusen, Birgit
    Within dynamic 21st century knowledge economies, future-building knowledge, that bears capacities to transcend existing boundaries and create something new, is of particular importance. Within the first decade of the new century, new concepts such as "learning from the future" or "self-transcending knowledge" developed within knowledge management. So far, they lacked a theoretical grounding in relevant learning theory as well as a sound acknowledgement and consideration of such knowledge structures' emergence and social embeddedness. Thus, key principles and leverage factors for designing respective knowledge processes were difficult to derive. This dissertation investigates theoretical ground that can provide a basis to explain the...

  12. The Role of Information Security Awareness for Promoting Information Security Policy Compliance in Banks

    Bauer, Stefan
    Banks rely heavily on information security (IS) by preserving confidentiality, integrity, and availability of information. A key layer for ensuring information security is the employees, who need to be aware of possible information security issues and behave accordingly. Banks introduce information security policies (ISP) to establish required rules for IS behavior and implement information security awareness (ISA) programs, which are systematically planned ISA interventions such as structured campaigns using intranet messages or posters to educate employees and enhance their ISA. According to previous conceptual research, the most cost-effective method to prevent IS incidents is fostering ISA. The purpose of this dissertation...

  14. Macroeconomic Applications of Bayesian Model Averaging

    Moser, Mathias
    Bayesian Model Averaging (BMA) is a common econometric tool to assess the uncertainty regarding model specification and parameter inference and is widely applied in fields where no strong theoretical guidelines are present. Its major advantage over single-equation models is the combination of evidence from a large number of specifications. The three papers included in this thesis all investigate model structures in the BMA model space. The first contribution evaluates how priors can be chosen to enforce model structures in the presence of interactions terms and multicollinearity. This is linked to a discussion in the Journal of Applied Econometrics regarding the...

  15. The Impact of a Harmonized European Corporate Tax Base on Investment Decisions of Multinationals

    Ortmann, Regina
    My dissertation scrutinizes the implications of a harmonized European corporate tax system for firms' and businesses' decision-making. Specifically, I examine the cross-border consolidation of profits and losses, the design of the apportionment formula applied to allocate the consolidated tax base to single group entities, and the locational investment decisions that are mainly driven by the consolidation of the tax base and its allocation to the group entities. All of my analyses are conducted using model-theoretical methods and simulations, a partial equilibrium business perspective is maintained throughout. (author's abstract)

  16. A broader perspective on the European Raw Materials Initiative

    Dieter, Armin
    Raw materials are the physical basis of the economy and society. Their unique physio-chemical properties provide the functionalities essential to the functioning of technologies. Some of them are essential to the functioning of key and sustainable technologies, which are provisioned to contribute to the transition towards a more sustainable European economy and society. For safeguarding the undistorted supply of raw materials, and in particular of these functional raw materials, the European Commission proposed the European Raw Materials Initiative (RMI). As a strategic policy framework the RMI focuses at ensuring a reliable supply of raw materials from international and European sources....

  17. Integration and Test of MOF/UML-based Domain-specific Modeling Languages

    Hoisl, Bernhard
    In model-driven development (MDD), domain-specific modeling languages (DSMLs) are used as tailor-made software languages targeting dedicated application domains. Due to the narrow domain coverage of DSMLs, demands to integrate their individual functionality into a consolidated DSML arise (e.g., developing a software product combining two or more pre-existing DSMLs). However, in order to realize the benefits of integrated DSMLs, it must be ensured that the integrated DSML is correctly implemented and behaves as specified. To support the integration and the test of DSMLs, this thesis presents an approach targeting the Meta Object Facility (MOF) and the Unified Modeling Language (UML)- a...

  18. Linguistic Refactoring of Business Process Models

    Pittke, Fabian
    In the past decades, organizations had to face numerous challenges due to intensifying globalization and internationalization, shorter innovation cycles and growing IT support for business. Business process management is seen as a comprehensive approach to align business strategy, organization, controlling, and business activities to react flexibly to market changes. For this purpose, business process models are increasingly utilized to document and redesign relevant parts of the organization's business operations. Since companies tend to have a growing number of business process models stored in a process model repository, analysis techniques are required that assess the quality of these process models in...

  19. An International Perspective on Aging and Cognitive Decline

    Weber, Daniela
    Worldwide populations are growing older. Thus, many countries fear economic and societal burden, but population aging can also be seen as an opportunity for a society. Which view prevails is very much dependent on the chosen measures of aging that are so far mainly based on chronological age. In the first part of this thesis measures of population aging are analyzed and new measures are proposed. The novel cognition adjusted dependency ratio (CADR) is introduced as an alternative to the old-age dependency ratio (OADR), which only considers a chronological age threshold. A CADR based ranking of certain countries across the...

  20. Paris sehen... und ein Unternehmen gründen? Interkulturelle Erfahrung und das Erkennen von unternehmerischen Handlungschancen

    Vandor, Peter
    Internationale Migranten werden häufiger selbständig und gründen Unternehmen als Menschen ohne interkulturelle Erfahrung. Aktuelle Theorien legen nahe, dass ihre unternehmerische Aktivität durch spezielle Ressourcen und institutionelle Arrangements ausgelöst wird, die es attraktiver machen unternehmerische Chancen zu nützen, als Beschäftigung am Arbeitsmarkt zu suchen. Im Gegensatz dazu beschreibt diese Dissertation eine neue Perspektive auf das Phänomen. Sie entwickelt die Hypothese, dass interkulturelle Erfahrungen die Fähigkeit erhöhen, unternehmerische Chancen zu erkennen, indem sie Zugang zu neuem Wissen schaffen und kreatives Denken unterstützen. Die Ergebnisse einer Querschnittstudie (n=444) und eines longitudinalen natürlichen Experimentes (n=243) bestätigen die genannte und weitere Hypothesen und zeigen, dass...
