Component technologies are perceived as an important means to keep software architectures flexible. Flexibility offered by componenttechnologies typically addresses software developers at design time. However, the design of software which should support socialsystems, such as work groups or...

Virtuelle Organisationen zeichnen sich vor allen Dingen durch vier Eigenschaftender Organisationsmitglieder aus. Autonomie, hoher Grad an Heterogenität, räumlicheVerteiltheit und starke Nutzung vernetzter Computer. Dabei etabliert sich die virtuelleSphäre in der Wahrnehmung der Akteure auch...

This paper investigates the influence of personality traits on occupational choice using data of theGerman Socio‐Economic Panel. We conduct multinomial logit analyses to differentiate malemanagers, professionals, technicians, clerks, service workers, and manual workers with respect totheir...

We empirically investigate if tournaments between heterogeneous contestants are less intensive. To test our hypotheses we use professional sports data from the TOYOTA Handball-Bundesliga, the major handball league in Germany.[...]

Following tournament theory, incentives will be rather low if the contestants ofa tournament are heterogeneous. We empirically test this prediction using alarge dataset from the German Hockey League. Our results show that indeed theintensity of a game is lower if the teams are more...

We analyze a two-stage game between two heterogeneous players.At stage one, common risk is chosen by one of the players. At stagetwo, both players observe the given level of risk and simultaneouslyinvest in a winner-take-all competition. The game is solved theoreticallyand then tested by using...

We empirically investigate possible distortions in subjective performance evaluations. A keyhypothesis is that evaluations are more upward biased the closer the social ties betweensupervisor and appraised employee. We test this hypothesis with a company data set from acall center organization...

Die Aneignung und Einbettung von Computersystemen in den Nutzungskontext stellt einen zentralen, nichtsdestotrotz von der bisherigen Forschung ungenügend adressierten Aspekt der Softwarenutzung dar. Es muss dabei klar sein, dass Aneignung ein kollektiver und kreativer Prozess gesehen werden...

In this chapter we depict collaborative aspects of tailoring software. We provide a categorization distinguishing between three levels of intensity of user ties regarding tools usage (“shared use”, “shared context”, and “shared tool”) and discuss approaches to support collaborative...

This thesis contributes to the field of collaborative information systems and Computer-SupportedCooperative Work (CSCW). It extends the notion of technological support for design activities "inuse" beyond providing the flexibility to tailor collaborative software, to provide means to support...
