Care-Politiken,Care-Arbeitsmarkt und Ungleichheit: Schweden,Deutschland und Italien im Vergleich

Social and demographic changes in western societies have led to a (re-)definition of social rights related to care-dependency and the introduction of further regulations of formal and informal care delivery. Care has increasingly become provided in the public sectors – the state, market and civic sector – and new types of cash benefits to support informal family care have been introduced. In this article, the concept of social care is used as a theoretical tool to analyse the relationship between the (re-)definition of social rights, the growth of a regular or grey care labour market and the related development of new forms of inequality according to socio-economic class and ethnicity in the female dominated area. The empirical comparison of the developments in Sweden, Germany and Italy reveals the dimensions of social rights – eligibility criteria, level and types of benefits – which are decisive for the growth of a regular and grey care labour market and the intersection of different forms of inequality.     

Nationale und globale Ungleichheit

The impact of globalization on the structure of social inequality is controversial discussed in actual debates. The national focused research is challenged by globalists. The article concentrates on the problem of order and shows how this is solved by the national structures of social inequality. In the next step the reasons for and against the national solution are presented. Finally the possibility of transnational constituting structures of social inequality is examined. How probable is the structuration of global inequality if basic elements of order are missing on this level?     

Relationships between Social Information Processing and Aggression among Adolescent Girls with and without ADHD

This study investigated the relationship between social information processing (SIP) and both relational and overt, physical aggression in a longitudinally-followed sample of 228 adolescent girls (ages 11–18; 140 with ADHD and 88 comparison girls). During childhood, girls participated in naturalistic summer camps where peer rejection, overt physical aggression, and relational aggression were assessed via multiple informants and methods. Approximately 4.5 years later, these girls participated in follow-up assessments during which they completed a commonly-used vignette procedure to assess SIP; overt and relational aggression were again assessed through multiple informants. Correlations between (a) overt and relational aggression and (b) maladaptive SIP were modest in this female adolescent sample. However, relationships between aggression and SIP were stronger for the comparison girls than for the girls with ADHD. The relevance of SIP models for adolescent girls and clinical implications of findings are discussed.

Adolescent Siblings’ Looking Glass Self-Orientations: Patterns of Liabilities and Associations with Parenting

A looking glass self-orientation refers to the tendency to incorporate the opinions of social partners to form a self-representation and approve of one’s self. These orientations were assessed for two adolescent siblings in 438 families with surveys accessed on-line. Younger (M = 11.6 years, SD = 1.8) and older (M = 14.3, SD = 2.1) siblings and their mothers (82.7% European-American) participated. The siblings shared similar orientations in relying on either classmates or the other sibling for approval, prior to self approval. Relying on classmate approval was significantly associated with adjustment and academic performance as reported by both the self and mothers. Siblings were also identified as sources of approval with implications for adjustment, but the magnitude of the associations with adjustment were lower. Comparisons of the older and younger siblings revealed that both groups were equally as liable to poor outcomes when reflecting the opinions of classmates or siblings. The results of SEM analyses implicate parenting characterized as coercive, rejecting, and chaotic in association with the tendency to rely on others for approval. A mediating role for looking glass self-orientations in associations between parenting and depressive symptoms, anxiety or academic performance was also found.
