Förståelse, bedömningar och hjälpinsatser : Socialarbetares arbete med män som våldsoffer

This report outlines the background to, and presents the results from the Crime Victim Compensation and Support Authority funded project "Social Workers' understanding of men as victims of crime". The project aimed at describing and analyzing how social workers understand and work with male victims of violence. More precisely, the research has focused on how social workers describe men's vulnerability and how they understand men's needs for assistance, what assistance that is provided and the way the constellations of perpetrators and victims of different gender and contexts in which the violence occurs in affect the understanding of male victims of violence. The study has also been devoted to the question of whether the Support Centers for young crime victims in Sweden provide different types of and different amount of help to young men and women afflicted of violence. The project was conducted in three substudies. The results from substudy 1 show that more young men than women seek support from the Support centers studied. Men predominate in number of cases and in the different categories of crime. The results also show that young men on average receive less assistance over a shorter average duration than young women. This applies irrespective of the category of offense that the vulnerability applies to. Furthermore, the young men, compared to the women, proportionally receive fewer interventions characterized as support and a greater proportion of interventions in the form of information. The results also show that the young men are referred on for further action to a lesser extent than is the case for women. The results from substudy 2 show that social workers tend to focus on whether, and to what extent, young men who are victims of violence themselves have behaved provocatively before the violence incident and if they have put themselves in a social situation that could be interpreted as having contributed to an escalation of the violence they have been subjected to. The results from substudy 2 also show that social workers talk about the men as active in the violent situations they have been involved in and dwell on the extent to which the young men's own actions have contributed to the violence. The results also show that young men who are victims of violence are described as "reluctant" victims who are trying to cope with their situation on their own without the involvement of professional or other helper. The young men are also described as reluctant to talk about their feelings. The results of substudy 3 show that social workers believe that young men, when they become victims of violence, risks losing their sense of autonomy, initiative and decisiveness, that is, attributes that are often linked to the dominating cultural image of masculinity. Furthermore, the results show that social workers estimate that men's practicing of their masculinity, but also the response that men who are traumatized get from society, creates difficulties for them to get help. The results from substudy 3 also shows that attributes and actions that can be connected to the masculinity of young men's, as well as a lack of such attributes and actions are considered to be adequate explanations for the violence the men has suffered. When it comes to violence in public places it is the masculinity that explains the violence and its escalation. When it comes to domestic violence it is the lack of expected male attributes and actions that are used as explanations for the violence that have occurred. The discussion is devoted to the question of how the results should be understood based on the concepts of self-performance, interpretation, negotiation and categorizations, and the consequences the results obtained should have for gender sensitive social work given to abused men.

Från nationsbyggare till global marknadsnomad : Om medborgarskap i svensk utbildningspolitik under 1990-talet

I den här avhandlingen är intresset riktat mot svensk utbildningspolitik och medborgarskap. I tider av globalisering, och med ett etablerat svenskt medlemskap i Europeiska unionen, har det nationella policyskapandet kring utbildningens medborgardanande funktion hamnat under ökat tryck. I studien undersöks hur detta hanteras i svensk utbildningspolitik under 1990-talet, en tid som utmärker sig genom betydande förändringar på utbildningsområdet i Sverige. Frågan är, mera precist, vilken riktning för skolans, enligt lag befästa, uppdrag att fostra demokratiska medborgare som utstakas i svensk utbildningspolitik vid denna tid. Genom att fästa vikt vid mål, visioner och motiv som formuleras i utbildningspolitiska 1990-talstexter klarläggs förståelser av medborgarskap som karaktäriserar svensk utbildningspolitik under denna tid. Även en bredare historisk analys görs, ur vilken historiska målsättningar med skolans medborgarfostran som föregår 1990-talets framträder. Studiens syfte är kritiskt. Förståelserna granskas utifrån vad de innesluter och vad de utesluter, vilka möjliga konsekvenser de kan tänkas få för olika individer och grupper i samhället, och om det finns öppningar för tänkbara alternativ. Studien visar på två historiska skiften vad gäller medborgarskapets innehåll och mening i det inhemska policyskapandet. Det första skiftet äger rum under 1990-talets tidiga del. Då bryts en etablerad samhällsbyggande medborgarroll upp, till förmån för andra mera marknadsorienterade medborgarroller. Under 1990-talets senare del, då marknadsorienteringen förstärks i neoliberal riktning, sker ett andra skifte; en historiskt vedertagen gemenskapstanke – nationen – bryts upp som grund för medborgerlig gemenskap. Denna tanke ersätts av en annan som är globaliseringsinriktad, vilken visar sig ha andra inne- och uteslutande mekanismer för olika individer och samhällsgrupper. Utifrån dessa forskningsrön tecknas avslutningsvis några konturer till ett alternativt sätt att tänka kring medborgarskap och gemenskap. Detta alternativ tar form i ambitionen att, i högre grad än vad som blir synligt i svensk utbildningspolitik, resonera kring möjligheter för ett medborgarskap bortom förhandstecknade indelningsgrunder för ett “vi”. Språk som politisk och samhällelig förändringskraft ges en central betydelse i avhandlingen. I analysen av texternas tal om skolans medborgarfostrande roll undersöks pågående politiska motsättningar när det gäller att vinna tal- och tolkningsföreträde till skolans fostransmål. Utgångarna av dessa motsättningar belyses genom tre områden för medborgarfostran som urskilts som centrala; ett politiskt, ett kulturellt samt ett ekonomi- och arbetslivsriktat. Genom dessa har rådande medborgarskapsdiskurser tagit form, ur vilka de utbildningspolitiska förståelserna av medborgarskap gestaltas och diskuteras.

Design and application of experimental methods for steel sheet shearing

Shearing is the process where sheet metal is mechanically cut between two tools. Various shearing technologies are commonly used in the sheet metal industry, for example, in cut to length lines, slitting lines, end cropping etc. Shearing has speed and cost advantages over competing cutting methods like laser and plasma cutting, but involves large forces on the equipment and large strains in the sheet material. The constant development of sheet metals toward higher strength and formability leads to increased forces on the shearing equipment and tools. Shearing of new sheet materials imply new suitable shearing parameters. Investigations of the shearing parameters through live tests in the production are expensive and separate experiments are time consuming and requires specialized equipment. Studies involving a large number of parameters and coupled effects are therefore preferably performed by finite element based simulations. Accurate experimental data is still a prerequisite to validate such simulations. There is, however, a shortage of accurate experimental data to validate such simulations. In industrial shearing processes, measured forces are always larger than the actual forces acting on the sheet, due to friction losses. Shearing also generates a force that attempts to separate the two tools with changed shearing conditions through increased clearance between the tools as result. Tool clearance is also the most common shearing parameter to adjust, depending on material grade and sheet thickness, to moderate the required force and to control the final sheared edge geometry. In this work, an experimental procedure that provides a stable tool clearance together with accurate measurements of tool forces and tool displacements, was designed, built and evaluated. Important shearing parameters and demands on the experimental set-up were identified in a sensitivity analysis performed with finite element simulations under the assumption of plane strain. With respect to large tool clearance stability and accurate force measurements, a symmetric experiment with two simultaneous shears and internal balancing of forces attempting to separate the tools was constructed. Steel sheets of different strength levels were sheared using the above mentioned experimental set-up, with various tool clearances, sheet clamping and rake angles. Results showed that tool penetration before fracture decreased with increased material strength. When one side of the sheet was left unclamped and free to move, the required shearing force decreased but instead the force attempting to separate the two tools increased. Further, the maximum shearing force decreased and the rollover increased with increased tool clearance. Digital image correlation was applied to measure strains on the sheet surface. The obtained strain fields, together with a material model, were used to compute the stress state in the sheet. A comparison, up to crack initiation, of these experimental results with corresponding results from finite element simulations in three dimensions and at a plane strain approximation showed that effective strains on the surface are representative also for the bulk material. A simple model was successfully applied to calculate the tool forces in shearing with angled tools from forces measured with parallel tools. These results suggest that, with respect to tool forces, a plane strain approximation is valid also at angled tools, at least for small rake angles. In general terms, this study provide a stable symmetric experimental set-up with internal balancing of lateral forces, for accurate measurements of tool forces, tool displacements, and sheet deformations, to study the effects of important shearing parameters. The results give further insight to the strain and stress conditions at crack initiation during shearing, and can also be used to validate models of the shearing process.
