In this paper a person-centered, actor-driven project simulation approach is presented that can cope with highly parallel tasks in multiple projects and can, therefore, help managers to plan concurrent product development projects. The task execution sequence is determined by means of a bounded rational choice model accounting for the urgency of tasks. The model creates realistic project dynamics using only a small number of input parameters. The project manager is, for instance, not forced to specify fixed predecessor-successor-relations of tasks. The model was validated with historical project data from a company of the German electronics industry. Using Student's t-tests the simulated project durations showed no significant derivation from the historical duration. [ABSTRACT FROM AUTHOR]

One of the important measures to prevent industrial accidents consists in informing a machine operator about the appearance of hazardous situation quickly and effectively enough. The main aim of the paper is to present and discuss a methodology of proving - by means of the perception assessment - that the warning signals generated using the AR approach reveal the same effectiveness as standard visual signals coming from an industrial signalling device that is of common use in machinery. Twenty volunteers constituted a paid subject population for the study. In the course of experimental task execution the warning visual signals were generated using either a standard industrial signalling device or augmented reality glasses. Despite the fact that the experimental procedure has not been completed yet very promising primary results have been obtained has indicating that both the objective and subjective assessment indicators are better for the AR warning signals.

International customer demands in the capital goods industry force providers of industrial services to be present on a global market. Often this can only be realised efficiently by cooperating with other partners. But the process to configure a cooperation and choose an adequate cooperation alternative still lacks adequate support. Existing approaches to evaluate services or cooperation are not suitable for an assessment of different alternatives prior to their implementation. Simulation approaches for production networks on the other hand, cannot be used for industrial services. This paper deals with an approach to overcome this problem and presents a simulation model based on Petri net theory for the prospective analysis of cooperative provision of industrial services. To achieve this goal, a domain-specific conceptual model of cooperative provision of industrial services has been developed that considers the constitutive characteristics of industrial services and their cooperative provision and maps them onto the formal notation of coloured Petri nets to form an executable simulation model. As a result, machine and equipment producers will be able to assess their cooperation alternatives related to integrated service provision in advance and thus avoid cost-intensive false decisions.

Organised crime did not become a topic of great interest in Germany until the 1980s. First arising in police discussions, the threat posed by organised crime rapidly became an increasingly important issue in the political and public debate during the following decade. At the same time, significant changes were made to the criminal justice system, which have affected both the legislative framework and the praxis of criminal prosecution. [ABSTRACT FROM AUTHOR]

In an interview with a deaf gay man who is part of the leather community, he describes his sexual experiences and his deaf culture. The man's attraction to men in uniforms and the implication of authority. His sexual experiences including spanking, shaving, and golden showers. Trust is important in his sexual relationships. The reaction of his parents to his nipple rings. Qualities that the man's ideal partner must have including intelligence, commitment, and knowledge of deaf culture. He discusses why he is turned on by leather including that leathermen are more down-to-earth, unlike more materialistic gay men.
