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. 相似文献

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? 相似文献

The purpose of this study was to gain a clearer understanding of the relation between parents’ knowledge of their emerging-adult
children and emerging adults’ risk behaviors. Participants included 200 undergraduate students between the ages of 18 and
25 (121 women, 78 men; M
age = 19.59, SD = 1.62) and both of their parents. Results revealed that knowledge of the emerging-adult child’s activities varied as a function
of parent- and child-reports, and that child outcomes associated with parental knowledge were generally positive, including
less drinking, drug use, and risky sexual behavior (although this varied as a function of reporter). The links between maternal
knowledge and lower drug and alcohol use were particularly strong in the presence of maternal closeness. Implications for
understanding the parent–child relationship during the transition to adulthood were discussed.

This study investigated a multi-mediation model of the relationship between bullying behavior, peer victimization, personal
identity, and family characteristics to adolescent depressive symptoms in 194 high school students, 12–18 years of age. In
the first model, peer victimization mediated the relation between bullying behavior and depressive symptoms. In the second
model, personal identity mediated the relation between peer victimization and depressive symptoms. In the final model, the
two mediation models were combined. The relative influence of family characteristics on all variables in the two mediation
models was studied using structural equation modeling. The results supported both mediation models and confirmed the influence
of family characteristics on all variables in the mediation models. This study indicates that victimization by one’s peers
has consequences for adolescents’ psychological health when their personal identity is affected. In addition, the study was
able to model several processes in which family characteristics were related to adolescent depressive symptoms. Moreover,
the final combined model (in which the two mediation models and the influence of family characteristics on all variables were
confirmed) explained half of the variance in adolescent depressive symptoms.

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.

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.

When does the Gender Difference in Rumination Begin? Gender and Age Differences in the Use of Rumination by Adolescents 总被引:1,自引:0,他引:1
A cross-sectional non-clinical sample of 1,218 adolescents, aged 10–17 years, completed measures of stress, rumination, and
depression to allow tests of the response style theory of S. Nolen-Hoeksema [J Res Adolesc 4:519–534, 1994] in adolescents,
in particular whether increasing levels of stress and rumination in early adolescence are predictive of the onset of the gender
difference in depression. Overall, females reported higher levels of stress, rumination, and depression than males. The onset
of the gender differences in stress and depression occurred at age 13 years, and for rumination one year earlier at 12 years.
Significantly, also from 13 years, rumination explained the gender difference in depression by showing that it significantly
mediated the effect of gender on depression. Gender moderated the rumination to depression relationship; specifically the
association was stronger for females than males. Developmental differences were noted in that rumination significantly mediated
between stress and depression earlier in the age range for females than males. Results supported many of the predictions of
Nolen-Hoeksema’s model of the emergence of a gender difference in adolescent depression.

Being a victim of sexual aggression from a peer is a common experience among adolescents and poses a significant risk for
various forms of psychopathology. Unfortunately, little is known concerning specific interpersonal factors that increase an
adolescent’s risk for experiencing sexual aggression. The current study assessed the contribution made by several interpersonal
factors both for the first and repeated experience of becoming a victim of sexual aggression from a peer. Data were collected
annually from a longitudinal sample of 200 adolescents over a period of 4 years and were analyzed using multiple-spell, discrete-time
survival analysis. Approximately 46% of the adolescents reported experiencing some form of sexual aggression by the end of
wave 4. Further, 65% of victims reported experiencing a repeat incident of aggression. Females were at higher risk both for
initial and repeated victimization, as were adolescents with more sexual experience and higher levels of rejection sensitivity.
Results are discussed in terms of implications for future prevention efforts.

This study examined the relationship between limited English proficiency status, and internalizing and externalizing behaviors
among a sample of Latino/a children (N = 2,840) from the US Department of Education’s Early Childhood Longitudinal Study, Kindergarten (ECLS-K) data set. Results
of cross sectional regression and hierarchical linear modeling (HLM) analyses suggest that there is a positive relationship
between limited English proficiency and externalizing symptoms, particularly by third grade. Additionally, sex and place of
birth also helped to explain externalizing behaviors at various time points in the models. Place of birth and family poverty
were significantly associated with internalizing symptoms. Implications for future research and interventions related to internalizing
and externalizing behavior among the Latino/a school aged population are discussed.
