Vis-à-vis vs. mixed dock door assignment: A comparison of different cross dock layouts

An important decision problem during the layout phase of a cross dock is related to the arrangement of inbound and outbound operations within a terminal. Either one side of the terminal is exclusively dedicated to inbound and the other to outbound destinations (vis-à-vis policy) or inbound and outbound destinations can facultatively be assigned all around the terminal (mix policy). The latter policy promises more flexibility, when finally assigning dock doors to truck destinations during operational planning, but comes for the price of ambiguous material flows and potential congestions inside the terminal. Both policies are compared with regard to their impact on operational planning, where deterministic, stochastic and unknown inbound loads are differentiated. Our results show the mix policy being superior in most cases except for unknown inbound loads.     

How do the employment effects of job creation schemes differ with respect to the foregoing unemployment duration?

Based on new administrative data for Germany covering entrances into job creation schemes between July 2000 and May 2001, we evaluate the effects of this active labour market policy programme considering the timing of treatment in the individual unemployment spell. Applying propensity score matching in a dynamic setting where the time until treatment in the unemployment spell is stratified into quarters, regional (East and West Germany) as well as gender differences are considered in the estimation. The results in terms of employment present a heterogeneous, but disappointing picture. For West Germany, most of the estimates are insignificant at the end of the observation period, and only one positive exception could be established. In East Germany, none of the groups experiences an improvement of the labour market situation, but the employment chances tend to be reduced due to participation even 30 months after start of programmes.     

Asymmetric information in bilateral trade and in markets: An inversion result

I consider bilateral trade between a seller and a buyer with private valuations. The seller makes a take-it-or-leave-it price offer. If the seller observes the buyer?s valuation (symmetric information), bilateral trade is trivially efficient. If the seller cannot observe the valuation (asymmetric information), bilateral trade is inefficient. This bilateral trading game is embedded into a large matching market. In the steady-state equilibrium of the market game, the relation between the informational regime and efficiency is inverted: With small frictions efficiency obtains if information is asymmetric. If information is symmetric, however, the trading outcome can be very inefficient—even if frictions vanish.     

??ber Terroristen und Spitzensportler

Islamophobia is more strongly developed in East Germany compared to the western part of the country. Given the lack of personal contact with Muslims in East Germany, islamophobia is probably strongly influenced by media coverage. For this reason, the coverage of two East German regional newspapers, Nordkurier and Volksstimme, is analyzed against the theoretical background of a conjunction of the social-psychological stereotype content model with the communication-scientific concept of framing. Using content analysis and latent class analysis, two so-called stereotype frames were identified. Two thirds of all Islam-related articles use the ??cold and harm frame??. Here, Muslims are often blamed for the lethal consequences of terrorist action, their behaviour is evaluated as cold or immoral, and military interventions against them are discussed. On the other hand, one third of all Islam-related articles belongs to the ??competence and cooperation frame??. Competence is ascribed to Muslims as their success in artistic, athletic or political activities is recognized and other actors?? interest in cooperation in these areas is emphasized. Whereas the ??cold and harm frame?? probably promotes medial segregation, the ??competence and cooperation frame?? is representing an assimilative model of media integration.     

Governance modes for offshoring activities: A comparison of US and German firms

A new field of research centered on the offshoring of white-collar tasks is opening. We analyze the choice of governance mode for international offshoring activities based on a four-fold framework that integrates multiple theoretical perspectives. Firms choose between an internal or external mode based on their institutional environment, the offshoring behavior of similar firms in their reference group, firm-specific characteristics and objectives, and the particular setting of specific implementations. We test our relationships using detailed data on offshoring activities of US and German firms. Based on the outcomes we conclude that each dimension of the chosen framework is needed to explain the governance mode decisions of firms and this overarching framework may also be applicable to other topics in internationalization research.     

Be Berlin! Governing the City through Freedom

In this article, I examine how contemporary Berlin is governed, with a particular focus on the production of urban space. My points of reference are the term ‘government’ (as employed by Foucault) and the field of governmentality studies (where it is applied empirically). Based on a critical discourse and dispositive analysis of the city's current urban development policy, I propose that urban governance in Berlin may be analysed through the lens of three central dispositives: the dispositive of governing through citizenship; the dispositive of the creative city; and the dispositive of the social city. I discuss the characteristics of these dispositives of urban governance, drawing on a number of examples taken from the discipline of urban space production in order to look specifically at the aims and objectives of governance, its subjects and the ways it manifests itself. In conclusion, I suggest that the new forms of governance based on empowerment and cooperation have by no means replaced disciplinary technologies of governance, but are rather embedded within them.     

Union absorptions in times of restructuring: the importance of attitude towards merger in predicting post‐merger attachment levels

Unions frequently restructure through merger, most often in the form of absorptions involving one bigger union absorbing a smaller one. However, the individual‐level effects of merger resulting in big amorphous organisations remain unclear. In this article, we highlight the role of the individual member in union absorptions, and investigate the relative importance of being a member of a large absorbing union or a small absorbed union, as well as the attitude of members towards merger in predicting post‐merger member attachment. The results from longitudinal data before and after absorption showed that members' attitude towards merger significantly predicted the members' attachment levels after absorption—this was, however, not the case for union commitment. We also uncovered a significant interaction indicating that the effect of members' attitude towards merger was more strongly related to perceptions of union support and instrumentality among members of the absorbed union.
