Generating Dutiful Members in Communities of 'Rational Choice'

The study 'Youth Welfare as Prevention - The reconfiguration of support and control in advanced liberalism' is part of the Graduate program 'Youth Welfare in Transition' funded by the 'German Research Association'. In empirical terms it is based on both interviews with professionals, reconstructive discourse analysis based on documents and programs as well as a secondary analysis of a range of existing studies.

Modeling and Vibration Suppression for Telescopic Systems of Structural Members with Clearance

Telescopic systems of structural members with clearance are found in many applications, e.g., mobile cranes, rack feeders, fork lifters, stacker cranes (see Figure 1). Operating these machines, undesirable vibrations may reduce the performance and increase safety problems. Therefore, this contribution has the aim to reduce these harmful vibrations. For a better understanding, the dynamic behaviour of these constructions is analysed. The main interest is the overlapping area of each two sections of the above described systems (see markings in Figure 1) which is investigated by measurements and by computations. A test rig is constructed to determine the dynamic behaviour by measuring fundamental vibrations and higher frequent oscillations, damping coefficients, special appearances and more. For an appropriate physical model, the governing boundary value problem is derived by applying Hamilton’s principle and a classical discretisation procedure is used to generate a coupled system of nonlinear ordinary differential equations as the corresponding truncated mathematical model. On the basis of this model, a controller concept for preventing harmful vibrations is developed.

Attributions of Responsibility for Terrorist Attacks: The Role of Group Membership and Identification

Three studies examine how people’s attributions of responsibility for terrorist attacks depend on their group membership and their identification with the victim (study 1) or their identification with the victim’s or perpetrator’s ingroup (studies 2 and 3). We observe that people’s group membership (perpetrator group versus victim group) determines the judgments of responsibility for recent terrorist attacks. Members of the perpetrator group hold the direct perpetrators responsible, while members of the victim group perceive the perpetrator world as a whole as relatively responsible as well. Identification with the victim (study 1) or victim group (studies 2 and 3) strengthens attributions of responsibility to the whole perpetrator group, and this relationship is partially mediated by the perceived typicality of the perpetrator for the whole group. We discuss possible explanations for this pattern, and indicate the implications of these results in terms of improving intergroup relations.
