Sozialstrukturelle Interessenlagen und Parteipräferenz in Deutschland

Based on Allbus data, stability and change of the impact of social structurally defined interests on party preference in Germany is investigated. We use both traditional cleavage indicators like union membership or frequency of church attendance and further social structural characteristics like class identification, occupation or unemployment experience. We apply a two-level model with varying intercepts for the 16 Allbus surveys from 1980 to 2008. Beyond the expected results we observe some deviations from the stable relationship between social structural variables and party preference. (1) The younger generation of active Catholics prefers the Christian Democrats less than the older cohorts and the East German working class leaned towards this party immediately after unification. (2) Union members got alienated from the Social Democrats since 2004 due to reforms of unemployment benefits for people being out of work for a longer period of time with the consequence that Die Linke could profit from this trend in West and East Germany. (3) This left socialist party and its forerunner, the PDS, has always been the preferred party of people with unemployment experience. (4) The Greens and the Liberal Party are enduringly supported by specific social groups, the Greens by the social and cultural service class and the FDP by the self-employed, at least since this latter party ended the social liberal coalition with the SPD in 1982.     

User involvement during information systems development: a comparison of analyst and user perceptions of system acceptance

A sample of 150 users and analysts from multiple organizations and many system projects provided field questionnaire data to test hypotheses about the differences in their perceptions of user involvement (UI) and system acceptance. The Franz and Robey [Franz, C.R., Robey, D., 1986. Organizational context, user involvement, and the usefulness of information systems. Decision Sciences, Vol. 17, No. 3, pp. 329–356.] instrument was used for data collection and factor analyzed, resulting in more focused and specific measures. Analysis of the data showed that users and analysts did not agree on the user's involvement nor did they agree on their perceptions of the acceptability of the system to the user. Relationships of self-ratings of UI with system usage and system acceptance by the user demonstrated high correlations, which were attributed to the narrow focus of the UI and system acceptance measures rather than the original more global measure. Analyst perceptions of UI showed no correlation with a user's perceptions of system acceptance.     

Bayesian group belief

If a group is modelled as a single Bayesian agent, what should its beliefs be? I propose an axiomatic model that connects group beliefs to beliefs of the group members. The group members may have different information, different prior beliefs and even different domains (algebras) within which they hold beliefs, accounting for differences in awareness and conceptualisation. As is shown, group beliefs can incorporate all information spread across individuals without individuals having to explicitly communicate their information (that may be too complex or personal to describe, or not describable in principle in the language). The group beliefs derived here take a simple multiplicative form if people’s information is independent (and a more complex form if information overlaps arbitrarily). This form contrasts with familiar linear or geometric opinion pooling and the (Pareto) requirement of respecting unanimous beliefs.     

Propositionwise judgment aggregation: the general case

In the theory of judgment aggregation, it is known for which agendas of propositions it is possible to aggregate individual judgments into collective ones in accordance with the Arrow-inspired requirements of universal domain, collective rationality, unanimity preservation, non-dictatorship and propositionwise independence. But it is only partially known (e.g., only in the monotonic case) for which agendas it is possible to respect additional requirements, notably non-oligarchy, anonymity, no individual veto power, or extended unanimity preservation. We fully characterize the agendas for which there are such possibilities, thereby answering the most salient open questions about propositionwise judgment aggregation. Our results build on earlier results by Nehring and Puppe (Strategy-proof social choice on single-peaked domains: possibility, impossibility and the space between, 2002), Nehring (Oligarchies in judgment aggregation: a characterization, 2006), Dietrich and List (Soc Choice Welf 29(1):19–33, 2007a) and Dokow and Holzman (J Econ Theory 145(2):495–511, 2010a).     

Business as unusual: Coaching in Echtzeit

Business as unusual: Coaching in real time Using the concrete example of a newly founded company, the authors demonstrate how executives and employees can keep themselves, their teams and organizational unity effective and capable of action in an increasingly dynamic, complex and changing world. These managers do not ?muddle through“, they seek functioning action-coalitions where they can act as individuals in interplay with others for the good of the commonly defined whole. Increasing the effectiveness of individual managers, their units and entire businesses, decisively depends on the promotion of trust co-operation, the development of common goals and reference frameworks, and potent jointly produced diagnoses. In successful cases this leads to coherence and sense emerging for individuals, their organizational units, overlapping working teams and, in the best case, for the whole business. The authors describe their supporting function in this process and call it real time-coaching.
