The time it takes a court to process its cases, a critical aspect of court performance, varies widely from case to case, from court to court, and within a given court as the court and its environment change over time. The sources of this variation, however, have remained largely obscure.
This paper examines the structural and case-level influences on processing times in three criminal courts experiencing structural changes, including a number of administrative reforms designed to reduce processing times. We find both similarities and differences between courts, but in general both many structural arrangements and many case characteristics affect processing times, with some case characteristics having different effects under different structural arrangements, and some structural arrangements affecting different sorts of cases differently. We conclude with a discussion of implications for court management.  相似文献

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.

This study examined dimensions of mothers’ and fathers’ involvement in adolescents’ romantic relationships when offspring were age 17. Using cluster analysis, parents from 105 White, working and middle class families were classified as positively involved, negatively involved, or autonomy-oriented with respect to their adolescents’ romantic relationships. Patterns of parental involvement were generally not associated with parent–offspring relationship quality at about adolescent age 13, but earlier parent–offspring relationship quality moderated the associations between parental involvement and adolescent romantic experiences at about age 18. Positive parent–offspring relationship quality buffered the effects of negative parental involvement, whereas poorer parent–offspring relationship quality was a more adaptive context for adolescents of autonomy-oriented parents. Discussion focuses on the importance of parenting practices in adolescent romantic relationships and the emotional climate of parent–offspring relationships as a developmental context for those practices.

Suicide is an important public health problem in China: It is the fifth leading cause of death in China, and suicide in China accounts for over 30% of the world's overall suicide deaths. The substantial burden due to suicide has not been well recognized. This study aims to provide an estimate of the socioeconomic burden of the suicide problem in China in terms of years of life lost (YLL) and to discuss its implications. Suicide rates and the related YLL by age, gender, and region (urban/rural) from 1990 to 2000 were estimated using the most recent data from the Ministry of Health of China. The suicide rate in rural China was three times higher than that in urban areas. Suicide completers in rural areas shared 90% of total YLL. Rural women aged 25-39 years contributed the largest share of YLL. Our results show that some population subgroups contributed a disproportionate share to the disease burden of suicide. National strategies for suicide prevention should include targeted programs in catering the need of these specified subgroups in China.  相似文献

The International Monetary Fund: A review of the recent evidence   总被引:1,自引:1,他引:0  
A review of recent quantitative studies on the International Monetary Fund reveals that much of the conventional wisdom is incorrect. Recent studies have demonstrated a new degree of methodological rigor, have drawn more heavily upon insights from political science, and have asked a number of new questions. We review studies of participation in IMF programs, design of IMF conditionality, implementation and enforcement of IMF conditions, conventional program effects and catalytic effects. At every stage, we find substantial evidence of the influence of major IMF shareholders, of the Fund’s own organizational imperatives, and of domestic politics within borrowing countries. We conclude that very little is known with certainty about the effects of IMF lending, but that a great deal has been learned about the mechanics of IMF programs that will have to be taken into account in order to obtain unbiased estimates of those effects.

In 2005 Indonesian and European institutes joined to start the first step for the implementation of an Ocean Operational System in the Indonesian archipelago. The system will support the decision making process for the sustainable use of marine resources, providing useful information and added value products as well as a service for an improved management of the sea with high business impact to targeted groups as public authorities and commercial operators (coastal managers, fishermen, shipping companies). In this paper the System is shortly described with its potential benefits and economic and social impacts.

Visas and work permits: Possible global negotiating initiatives   总被引:1,自引:0,他引:1  
We discuss global options for initiatives intended to ameliorate adverse impacts of visa and work permit systems used by national governments around the world. We first describe and document some of their effects, noting the relative lack of other research work on these issues. We then discuss proposals for a new and supplemental global visa structure which have been made as part of the Mode 4 GATS negotiations in the WTO, suggesting that the GATS/WTO may be an imperfect institutional location for negotiating on these matters. We then evaluate other approaches, including what realistically could be possible if a new body specifically created for global negotiation in the area were to be used.
