The sibling relationship has an important impact on children’s emotional functioning, but it is yet unclear whether and how sibling relationship quality affects adolescent depressive symptoms over time. This study contributes to existing knowledge by examining the relative importance of three aspects of sibling relationship quality (i.e., support, conflict and power balance) on the one hand and sibling depressive symptoms on the other hand in predicting adolescent depressive symptoms over time. Additionally, this study examined whether these influence patterns were moderated by perceived sibling relationship quality and by dyadic gender composition. Across six annual waves, 412 Dutch adolescents (57% boys; Mage?=?12.34 years) and their older siblings (47% boys; Mage?=?15.36 years) reported on depressive symptoms and sibling relationship quality. Cross-lagged panel analyses showed that only sibling depressive symptoms and not perceived relationship quality predicted adolescent depressive symptoms one year later. This effect was not moderated by sibling relationship quality or gender composition. These results indicate that sibling depressive symptoms may be a risk factor for adolescent depressive symptoms.

Although the oxytocin receptor gene (OXTR) is involved in aggression and social affiliation, it has not been examined in gene-environment interaction studies. This longitudinal study examined the effect of genetic variants in OXTR and its gene-environment interaction with perceived deviant peer affiliation in the trajectories of antisocial behavior in 323 adolescents (182 males) from 13 to 18 years. Annual assessments of reactive and proactive aggression, delinquency, and friends’ delinquency, as well as DNA at age 17 were collected. Gene-based tests yielded no main effect of OXTR, but revealed a significant gene-environment interaction in proactive aggression and delinquency. Variation in the OXTR might affect the influence of deviant peer affiliation on antisocial behavior, contributing to a better understanding of individual differences in antisocial behavior.

Governments use different regulatory instruments to ensure that businesses owners or “inspectees” comply with rules and regulations. One tool that is increasingly applied is disclosing inspectees’ performance information to other stakeholders. Disclosing performance information has consequences for street‐level bureaucrats because it increases the visibility of their day‐to‐day work. Using a survey (n = 507) among Dutch inspectors of the Netherlands Food and Consumer Product Safety Authority, this article shows that the disclosure of performance information has an impact on enforcement style at the street level. Findings show that perceived disclosed performance information positively enhances all three dimensions of street‐level bureaucrats’ enforcement style (legal, facilitation, and accommodation). This effect is strongest for facilitation and accommodation and weakest for the legal style. Perceived resistance by inspectees partly explains this effect. Contrary to expectations, more perceived disclosure does not result in more but in less perceived resistance of inspectees by street‐level bureaucrats.  相似文献

The present article analyzes a general approach of the development of public infrastructure provision (hereinafter PIP) organizational models focusing on the structure of the privatization, partnership, business, contractual, and financial models of Armenia. The adopted approach of using the general map of the PIP toolbox gives an opportunity to clearly understand various models of PIP in different countries, compare them on the basis of certain components and to make a ground for the development of the most efficient PIP organizational models in relevant countries. The article introduces a well-defined tool to find the differences within various projects.  相似文献

This article explores the strength and causal determinants of ideological thinking within Swiss local political parties. The concept of “ideologization” refers to (1): “horizontal couplings”, as they are manifested in intercorrelations between different opinions, and to (2) “vertical couplings” of specific opinions to abstract concepts of “left” and “right”. Results show high ideologization on the left‐center section of the LR‐scale, especially in the vertical dimension. On both sides of the spectrum, ideological constraints are significantly higher in larger communities than in than in smaller ones. Only in rather small communities, does ideologization correlate positively with the educational level, the modern occupational background of party members and the number of other local parties with which they have to compete. In communities of given size, ideological thinking is more pronounced when parties possess a small share of political power. Finally, it is found that ideological constraints have increased somewhat between 1989 and 2002.  相似文献

It is now widely understood that mobile phone use has beneficial effects on development in developing countries, but little is known about the effects at the household level. We examine the impact of mobile telephone use on household income using a unique cross-sectional data set from Uganda. We use a novel econometric technique to handle endogeneity, which models the correlation between the endogenous regressor and the error term with copulas. To the best of our knowledge, this is the first time that the copula method has been applied in the economic development literature. We find a positive impact of mobile phone use on income.  相似文献

Party support has a strong influence on candidate success in the primary. What remains unexplored is whether party actions during the primary are biased along racial and gender lines. Using candidate demographic data at the congressional level and measures of party support for primary candidates, we test whether parties discriminate against women and minority candidates in congressional primaries and also whether parties are strategic in their support of minority candidates in certain primaries. Our findings show parties are not biased against minority candidates and also that white women candidates receive more support from the Democratic Party than do other types of candidates. Our findings also suggest that parties do not appear to strategically support minority candidates in districts with larger populations of minorities. Lastly, we also find no significant differences in the effects of party support on the likelihood of success in the primary by candidate race or gender.  相似文献

Lifetime prevalence of opioid dependence is about 0.4% in western countries. Opioid‐dependent patients have high morbidity and mortality and a high risk of criminal behavior. Few studies have addressed the long‐term impact of opioid maintenance therapy on convictions and criminal behavior. The PREMOS study is a prospective, longitudinal, naturalistic clinical study of a nationally representative sample of 2694 opioid‐dependent patients to investigate convictions and criminal behavior at baseline and after 6 years of maintenance treatment. At follow‐up, 2284 patients still were eligible (84.7%). A comprehensive assessment including a patient and doctor questionnaire, and the EuropASI was completed at baseline and follow‐up. Data on criminality at follow‐up had been received for 1147 (70.6%) patients. A large number (84.5%) of them had been charged or convicted at any time before baseline assessment, most frequently with drug‐related offenses (66.8%), acquisitive crime (49.1%), or acts of violence (22.0%). Reported charges and convictions had declined to 17.9% for the last 12 months before follow‐up, which was also reflected by a significant decrease in the EuropASI subscore “legal problems” from 1.52 at baseline to 0.98 after 6 years. These data indicate a significant and clinically relevant reduction in criminal behavior in opioid‐dependent patients in long‐term maintenance treatment. Maintenance therapy is effective in the reduction in both narcotics‐related and acquisition crime.  相似文献
