Governance, management and performance in public networks: How to be successful in shared-governance networks

This paper compares four cases and explores the effects on network performance of network governance, coordination mechanisms, and the abilities of the network manager. The focus is on shared-governance networks, which are in general considered to have difficulties achieving high-level performances. The cross-case comparison suggests a relationship between coordination mechanisms and the way shared-governance networks are managed: in order to be successful, they must be able to rely on formalized mechanisms and make a pool of “network administrators” responsible for their governance.     

The State, the Market and Cultural Diversity

This essay compares the logic of states and the logic of markets in the management of cultural diversity. On the one hand, the economic logic of markets leads to an encouragement of a 'soft' cultural diversity associated with the marketing of exoticism in music, the arts and cuisine, for example. On the other hand, the liberal states are trapped between their willingness to recognize some form of diversity and their fear of seeing social cohesion harmed by this recognition. In other words, the essay applies Hollified's hypothesis about the liberal paradox in immigration policy to the sphere of cultural diversity in post-immigration situations.

The contribution of general features of body movement to the attribution of emotions

The present study was designed to assess the contribution of general features of gross body movements to the attribution of emotions. Eighty-five adult subjects were shown ninety-six videotaped body movements, performed by three actors. Each movement was determined by seven general dimensions: trunk movement, arm movement, vertical direction, sagittal direction, force, velocity and directness. Using rating scales, the subjects judged the compatibility of each movement with each of twelve emotion categories. The results showed which movement features predicted particular ratings. Emotion categories differed as to the amount, type, and weights of predicting movement features. Three factors were extracted from the original ratings and interpreted as Rejection-Acceptance, Withdrawal-Approach, and Preparation-Defeatedness.I wish to thank Jacques van Meel for his stimulating contribution to this study, and the reviewers for their comments on earlier drafts of the final report.     

Prüfungshonorare in Deutschland – Determinanten und Implikationen

The audit fees available since 2005 as a consequence of the Bilanzrechtsreformgesetz (commercial code reform act) show an extremely high supplier concentration on the German audit market of publicly listed companies. This justifies the assumption of audit fees above perfect market equilibrium prices. However, the complete collection and multivariate regression analysis of all relevant audit fee and client data document a 24 % decrease in audit fees in 2005 and an average 15 % decrease in the two subsequent years due to auditor changes. This can be interpreted as an indicator for price competition. In addition, the audit fee data shows that the audit fee decreases are only partially compensated by subsequent increases. As a consequence, there is no evidence for lowballing at present. Further time series are necessary to show if the current trend is sustainable.     

The Modeling and Seasonal Adjustment of Weekly Observations

Several important economic time series are recorded on a particular day every week. Seasonal adjustment of such series is difficult because the number of weeks varies between 52 and 53 and the position of the recording day changes from year to year. In addition certain festivals, most notably Easter, take place at different times according to the year. This article presents a solution to problems of this kind by setting up a structural time series model that allows the seasonal pattern to evolve over time and enables trend extraction and seasonal adjustment to be carried out by means of state-space filtering and smoothing algorithms. The method is illustrated with a Bank of England series on the money supply.     

Interpersonal Distances in Group Walking

The spatial organization of 1,020 groups comprised of adolescents and young adults, observed in an ecological setting while walking, was analyzed. Observations were made in an urban environment where walking speed could be considered. The results showed that male dyads and triads tended to walk abreast less often than female dyads. Mixed dyads walked abreast more often than same-sex dyads; and the males preceded the females in two-thirds of the cases. The male groups walked at a higher rate of speed than the female groups. Walking speed was correlated to misalignment between group members when walking. The most frequent spatial arrangement in triads was a “<” formation (as seen from above, while the walking direction was from left to right), with the middle individual positioned slightly behind in comparison to the lateral individuals. Groups comprised of more than three individuals tended to split themselves into single individuals, dyads, and triads.     

Internal slackening scoring methods

We deal with the ranking problem of the nodes in a directed graph. The bilateral relationships specified by a directed graph may reflect the outcomes of a sport competition, the mutual reference structure between websites, or a group preference structure over alternatives. We introduce a class of scoring methods for directed graphs, indexed by a single nonnegative parameter α. This parameter reflects the internal slackening of a node within an underlying iterative process. The class of so-called internal slackening scoring methods, denoted by λ ^α , consists of the limits of these processes. It is seen that λ⁰ extends the invariant scoring method, while λ ^∞ extends the fair bets scoring method. Method λ¹ corresponds with the existing λ-scoring method of Borm et al. (Ann Oper Res 109(1):61–75, 2002) and can be seen as a compromise between λ⁰ and λ ^∞ . In particular, an explicit proportionality relation between λ ^α and λ¹ is derived. Moreover, the internal slackening scoring methods are applied to the setting of social choice situations where they give rise to a class of social choice correspondences that refine both the Top cycle correspondence and the Uncovered set correspondence.
