The Current Discussion on Men and Masculinities

In the past gender specific problems were mainly discussed in a female perspective. In the meantime there is a rising attentiveness in the living conditions of men and their coping strategies within critical life events. In this paper an appropriate frame of reference is outlined which can be used in those areas of social work where men are already discovered as a target group with special difficulties and needs.

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.

Sexuality and the ‘Relations of Ruling’: Using Institutional Ethnography to Research Lesbian and Gay Foster Care and Adoption.

This article makes use of institutional ethnography to research foster care and adoption by lesbians and gay men, drawing on the work of the feminist sociologist Dorothy E. Smith in order to demonstrate the investigation of social work institutional categories and the ‘relations of ruling’. Through an analysis of the ways in which ‘gender’ and the idea of the ‘gender role model’ is used within the assessment of gay and lesbian foster carers and adopters, the author shows how these categories are produced and used to police relationship forms and to identify ‘deviant instances’.
