Open governance requirements are designed to improve accountability, which implies that transparent governments are more trustworthy stewards of their publicly invested power. However, transparency may also reduce institutional effectiveness and inhibit political compromise, diminishing the capacity to manage resources responsibly. We assess empirical support for these competing perspectives in the context of American state legislatures, many of which have become exempt from state sunshine laws in recent decades. We leverage variation in the timing of these legislative exemptions to identify the effect of removing transparency in a crucial governing institution on investors’ risk perceptions of states’ general obligation bonds. Our analysis of these data during the period 1995–2010 suggests that removing legislative transparency reduces state credit risk. We conclude that while openness in government may be normatively desirable, shielding legislative proceedings from public view may actually be better for states’ debt repayment capacity, improving their overall fiscal health.  相似文献

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 interdependency of ?production“ and ?reproduction“ has increasingly attracted the attention of the scientific community and the media. Biological and social reproductions are topics of family and gender studies: In family research reproduction is analysed as a basic function of the family; in gender research reproduction is mainly studied as a factor that effects social inequality. While sociological research was for a long-time concentrated on the ?conciliation“ of ?work“ and ?(family) life“, nowadays a change of perspective is necessary: How can employees maintain their psychological and physical strength when the work sphere becomes more and more flexible? How can they safeguard their social relationships? The article connects the categories ?work-strength –life-strength “ as a perspective that considers the structural and contradictory relationship of ?work“ and ?life“. With the concept of ?doing reproduction“, individual efforts are brought in the centre of research. Hereby is shown that the functionality of reproduction as a social sphere is fundamentally based on reproduction as an individual practice.  相似文献

Research examining the relationship between internalizing symptoms and antisocial behaviors has generally been cross-sectional in design. Thus, although extant data have substantiated a strong correlation between internalizing symptoms and antisocial behaviors, few studies have focused on describing the nature of the co-occurrence over time. This study examined the relation between growth in internalizing symptoms and longitudinal patterns of antisocial behavior in a sample of 283 inner-city males and their caregivers assessed as part of a longitudinal developmental risk study. Participants were assessed annually in four waves. Non-offenders and escalating offenders had lower levels of internalizing problems at wave 1 than did chronic minor and serious-chronic-violent offenders. Results revealed a developmental trend of decreasing internalizing problems across study years for most participants, as would be expected, with adolescents participating in serious, chronic, and violent patterns of antisocial behavior displaying greater internalizing problems than those participating in stable patterns of less serious or no antisocial behavior. Further, when there was escalation of seriousness and frequency of antisocial behavior, there also was increased internalizing problems relative to non-escalating juveniles. Results are discussed in the context of developmental psychopathology.

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.
