In guten wie in schlechten Tagen?

In this contribution the model of frame-selection as an approach to integrate “normative” and “rational” action is being used for the explanation of divorce, operationalized and empirically tested with data of the Mannheim Divorce Study. Not only the evident effect of the “framing” of marriage at the beginning on the subsequent stability of marriage is shown, even after introducing control variables, but also a non-trivial interaction that is predicted by the model and that can be regarded as a “hard” test of it, namely the interaction of the framing of marriage with the belonging to a certain marriage cohort. At the same time this contribution is also discussing possibilities and advantages of a “general” theory of action for the social sciences in general.     

Cognitive distortions about sex and sexual offending: a comparison of sex offending girls, delinquent girls, and girls from the community

Cognitive distortions about sexual offending were examined in 11 girls who committed sexual offenses, 12 girls who committed non-sexual criminal offenses, and 21 girls with no history of sexual of non-sexual offending. Participants responded to 12 vignettes that described sexual contact between an adolescent girl and a younger boy. The vignettes varied with respect to the sexual contact portrayed and the victim's response. Girls who had sexually offended were more likely to endorse statements reflecting the belief that the offender in a sexually aggressive vignette was not responsible for initiating the sexual contact. In addition, when the victim's response to the sexual contact was clearly negative, and the degree of contact was more serious, girls who had sexually offended demonstrated more distorted beliefs about the victim than the other two groups. Similarities and differences between the current findings and studies of distorted thinking in male sexual offenders are discussed.     

Stabilized‐Cycle Strategy for Capacitated Lot Sizing with Multiple Products: Fill‐Rate Constraints in Rolling Schedules

In practice, deterministic, multi‐period lot‐sizing models are implemented in rolling schedules since this allows the revision of decisions beyond the frozen horizon. Thus, rolling schedules are able to take realizations and updated forecasts of uncertain data (e.g., customer demands) into account. Furthermore, it is common to hold safety stocks to ensure given service levels (e.g., fill rate). As we will show, this approach, implemented in rolling schedules, often results in increased setup and holding costs while (over‐)accomplishing given fill rates. A well‐known alternative to deterministic planning models are stochastic, static, multi‐period planning models used in the static uncertainty strategy, which results in stable plans. However, these models have a lack of flexibility to react to the realization of uncertain data. As a result, actual costs may differ widely from planned costs, and downside deviations of actual fill rates from those given are very high. We propose a new strategy, namely the stabilized cycle. This combines and expands upon ideas from the literature for minimizing setup and holding costs in rolling schedules, while controlling actual product‐specific fill rates for a finite reporting period. A computational study with a multi‐item capacitated medium‐term production planning model has been executed in rolling schedules. On the one hand, it demonstrates that the stabilized‐cycle strategy yields a good compromise between costs and downside deviations. Furthermore, the stabilized‐cycle strategy weakly dominates the order‐based strategy for both constant and seasonal demands.     

Management und Marketing ferngesteuerter Dienstleistungen: Konzeptionelle Verortung, betriebswirtschaftliche Herausforderungen und k??nftige Forschungsaufgaben

The possibilities of service delivery have expanded vastly over the last years, mainly due to the rapid development of information and communication technologies. Modern forms of data transmission enable a technologically mediated delivery of a broad spectrum of services over great distances. These ??remote services?? gain more and more importance in business, yet have only attracted little attention in academic research so far. This overview article captures the state-of-the-art of research in this field and starts laying the groundwork for a thorough discussion of economically relevant aspects of remote services. Based on a definition and conceptualization of this new service type that considers current service typology, this article identifies specific challenges for management and marketing of remote services and deduces an agenda for future research.
