1. Evaluation of E-Participation Efficiency with Biodiversity Measures - the Case of the Digital Agenda Vienna - May, John; Leo, Hannes; Taudes, Alfred
We introduce the Effective Number of Issues measure for e-participation efficiency. This novel index is based on the Shannon entropy measure of biodiversity and summarizes the amount of information gained through an e-participation project in one number. This makes the comparison between different e-participation projects straightforward and lays the foundation for the rigorous analysis of success factors of e-participation projects in a data-driven way. After providing the formula and rationale for the new measure we use the ENI index to benchmark the idea generation process for the digital agenda Vienna against other projects. It turns out that the efficiency of...

4. Oblivion on the Web: an Inquiry of User Needs and Technologies - Novotny, Alexander; Spiekermann, Sarah
Unlimited retention of personal information on the web may harm individuals: employers can find youthful indiscretions on social media, and incorrectly low credit scores may haunt individuals for a lifetime. Currently, Europe revives the "right to erasure" as a first step towards a forgetting web. Early technologies implementing oblivion suffer from vulnerabilities and narrowly assume that users require information to be erased after a pre-determined time. But little is known about users' actual oblivion needs. A first study shows that users desire control over disclosed personal information to reduce pre-disclosure privacy concerns, and to delete harmful information after disclosure. In...

5. Supporting Social Entrepreneurs - The effects of organizational maturity and business model on perceived support needs - Vandor, Peter; Millner, Reinhard; Hansen, Hinnerk
Social Entrepreneurs tend to be characterized as "unusually resourceful in being relatively undaunted by scarce assets in pursuing their social venture" (Peredo/McLean 2006: 64) or "acting boldly without being limited by resources currently in hand" (Dees 2001: 4). Still, social entrepreneurs do not operate in a vacuum. They depend on various forms of support and resources to establish and grow their ventures and impact. Hence, the question of how to support social entrepreneurs and their initiatives becomes of increasing relevance (Lyon/Sepulveda 2009). In spite of the growing call for measures to enable social entrepreneurship on a broad scale (e.g. by the...

15. Explaining MCDM acceptance: a conceptual model of influencing factors - Maida, Martina; Maier, Konradin; Obwegeser, Nikolaus; Stix, Volker
The number of newly developed Multi-Criteria Decision Making (MCDM) methods grew considerably in the last decades. Although their theoretical foundations are solid, there is still a lack of acceptance and application in the practical field. The objective of this research is the development of a conceptual model of factors that influence MCDM acceptance that serves as a starting point for further research. For this purpose, a broad diversified literature survey was conducted in the discipline of technology adoption and related topics (like human computer interaction) with special focus on MCDM acceptance. The constructs collected within the literature survey were classified...

16. Psychology of Ownership and Asset Defense: Why People Value their Personal Information Beyond Privacy - Spiekermann, Sarah; Korunovska, Jana; Bauer, Christine
Analysts, investors and entrepreneurs have for long recognized the value of comprehensive user profiles. While there is a market for trading such personal information among companies, the users, who are actually the providers of such information, are not asked to the negotiations table. To date, there is little information on how users value their personal information. In an online survey-based experiment 1059 Facebook users revealed how much they would be willing to pay for keeping their personal information. Our study reveals that as soon as people learn that some third party is interested in their personal information (asset consciousness prime),...

17. The economic and environmental performance of distribution networks: A case study from the petrochemical industry - Treitl, Stefan; Jammernegg, Werner
Designing a company's distribution network is a challenging task that requires the consideration of different aspects. In this respect, especially trade-offs between, for example, operational costs and customer service are the focus of the companies' attention. However, growing concerns of governments and customers about environmental protection have raised awareness towards the environmental impact of operations. Activities associated with the distribution of products, i.e. transportation and warehousing, are not yet subject to strict environmental regulations, but this situation is expected to change soon. Companies must, therefore, start to concentrate not only on economic but also on environmental aspects in the design of their...

18. Industrieturbulenz in Österreich 1981-1994. Bestandsaufnahme und wirtschaftspolitische Perspektiven. - Hölzl, Werner; Hofer, Reinhold
Seit einigen Jahren spielt in der industriepolitischen Diskussion Industriedynamik eine wichtige Rolle. Unternehmensneugründungen werden als wirtschaftspolitisches Instrument betrachtet, welches der "neuen unternehmerischen Ökonomie" angemessen sei. Dieser Beitrag untersucht diese Fragen mit Hilfe einer ökonometrischen Studie von Eintritten und Austritten in der Österreichischen Industrie. Die Daten zeigen, dass die Industrieturbulenz in Österreich im internationalen Vergleich eher gering ist, sowie dass sie über die Zeit relativ konstant ist. Die im internationalen Vergleich geringe Industrieturbulenz in Österreich deutet darauf hin, dass in Österreich viele "sichere" und wenige "riskante" Projekte in neuen Unternehmen in Angriff genommen wurden. Der Befund spiegelt wieder, dass Österreich von...

19. The emergence of multinational firms from Eastern Europe in Austria - Altzinger, Wilfried; Bellak, Christian; Duris, Rudolf
The paper examines the question of the emergence of multinational firms from Eastern Europe in Austria on different levels of aggregation: The first part uses aggregated data on inward foreign direct investment (FDI) in Austria from Central- and East European Countries (CEECs). These data show the importance of outward FDI from CEECs directed to Austria. The second part analyses survey data on the basis of a mailing survey sent to 210 firms from CEECs registered in Austria. Although the response rate was low, an interesting picture emerges of outward FDI directed to Austria. Overall, Austria is an important host country...

20. Die Diffusion marktwirtschaftlicher Schlüsselkonzepte in Mittel- und Osteuropa. Eine linguistische Analyse. - Müller, Barbara; Petters, Johanna; Doleschal, Ursula
Unser Beitrag stellt einen Zwischenbericht über Ergebnisse des Projekts "Der Marktdiskurs als Indikator von Globalisierung und Transformation. Eine diskursanalytische Untersuchung marktwirtschaftlicher Schlüsselbegriffe in Russland und Tschechien" dar, welches im Rahmen des WU-Forschungsschwerpunktes "Management across Borders" am Institut für Slawische Sprachen durchgeführt wird. Das MaxB- Schwerpunktthema "Diffusion" wird dabei aus der Perspektive und mit Methoden der Linguistik aufgearbeitet. Wir betrachten Diffusion als einen interkulturellen Prozess im weitesten Sinne, nämlich als "die Ausbreitung und das Annehmen neuer Kulturelemente wie z.B. Ideen, Werte oder auch Managementpraktiken in einer Gesellschaft", also von Innovationen, welche "im Endeffekt technischen und sozialen Wandel bewirken" (Hoffmann/Doleschal, in Druck)....
