An exchange rate determination model for central banks' interventions in financial markets     

林浚清  黄祖辉  战明华 《浙江大学学报(A卷英文版)》2002,3(4)

We establish an exchange rate determination model for central banks' in terventions in financial markets. The model shows that central banks can adjust exchange rate by several policy instruments and that different instruments may h ave different effects on exchange rate determination. It specifies potential pol icy instruments for central banks as well as their policy effects. Based on thes e effects, feasible matches of policy instruments in contingent intervention are put forth.  相似文献   

Bystander Intervention in Cyberbullying     

Nicholas Brody  Anita L. Vangelisti 《Communication monographs》2016,83(1):94-119

Cyberbullying incidents often occur in the presence of other bystanders. The inaction of bystanders can augment the deleterious effects of bullying on a victim. However, bystanders can intervene to stop a cyberbullying incident or offer support to the victim. Two studies were conducted to examine variables that were expected to influence the propensity of a bystander to take action in cyberbullying incidents: the number of bystanders, the anonymity of the bystander, and the closeness between the bystander and the victim. Results supported the diffusion of responsibility effect. A higher number of bystanders was negatively associated with bystander intervention. Moreover, the perceived anonymity of bystanders was negatively related to the propensity to intervene, and closeness with the victim was associated with a greater tendency to intervene and support the victim. Altogether, the results shed light on the interplay of context, relationships, and technology in the behavior of bystanders to a cyberbullying episode.  相似文献

An intervention to improve sibling relationship quality among youth in foster care: Results of a randomized clinical trial     

《Child abuse & neglect》2017

Sibling programming is an important part of a prevention framework, particularly for youth in foster care. After children are removed from their families and placed into foster care in the aftermath of maltreatment, the sibling relationship is often the most viable ongoing relationship available to the child, and may be critical to a youth’s sense of connection, emotional support, and continuity. The promise of dyadic sibling programming in particular rests on the ability of interventions to enhance the quality of sibling relationships; yet little research exists that suggests that sibling interventions can improve relationship quality among foster youth. The primary aim of the current study was to examine the effects of a specific dyadic sibling-focused intervention for older and younger siblings on sibling relationship quality. One hundred sixty four dyads (328 youth) participated in the study, with each dyad consisting of an older sibling between 11 and 15 years of age at baseline and a younger sibling separated in age by less than 4 years. Hierarchical linear models were applied to self-reported, observer-reported and observational data over the 18-month study period. Findings suggest that the sibling intervention holds promise for improving sibling relationship quality among youth in foster care. Implications and future directions for research are discussed.  相似文献

Identifying effective interventions for promoting parent engagement and family reunification for children in out-of-home care: A series of meta-analyses     

《Child abuse & neglect》2019

BackgroundAn important obstacle for family reunification following child placement in residential care and other temporary out-of-home care services is the lack of engagement among parents.ObjectiveThe aim of this meta-analysis is to identify the most effective interventions to promote parental engagement and family reunification.Method and participantsEight studies, for a total of 2996 families, were used to conduct two series of meta-analyses. Each study examined the effectiveness of a goal-oriented parental engagement intervention, relative to a control group made up of parents who received standard services. Six moderators were analyzed: type of clinical modality, number of clinical strategies, sources of motivation for intervention, focus on the child care staff-parent relationship, child care staff training, and strategies to promote access to intervention.ResultsResults indicate that parents exposed to goal-oriented engagement interventions showed greater engagement (effect size d = 0.71, CI: 0.35–1.07, p < 0.001) and likelihood of reunification (effect size OR = 2.49, CI: 1.22–5.10, p < 0.05) than parents who received standard services. In particular, moderator analysis showed that parents who specifically participated in a family-focused intervention showed the highest engagement in comparison to parents involved in other types of interventions or who received standard services (effect size d = 1.08, CI: 0.58–1.59, p < 0.001). No moderators significantly explained heterogeneity of studies on family reunification.ConclusionOverall, the results underline the effectiveness of family-focused interventions to promote parental engagement. Nevertheless, greater knowledge on the mechanisms by which interventions can increase parents’ engagement and family reunification is still needed.  相似文献   

立法缺位状态下公立高校纠纷解决的路径分析     

刘志刚 《复旦教育论坛》2012,10(2):44-49

受诸多方面因素的影响,高校管理领域存在着立法缺位的现象,这种现象直到教育部2003年提出依法治校之后也并没有从根本上消失。高校发生的诸种管理纠纷就是置身于这种场景之下的。司法是解决高校行政纠纷的一种重要手段,但是它在解决纠纷时面临着许多突出的问题。对该类纠纷的根本性解决,不能单纯依靠司法审查制度,而应该在完善司法审查制度的同时,探求更为根本的路径。  相似文献
