Introduction to Social Network Analysis (SNA) as an investigative tool

Social behavior is brought about mainly through social ties and connections. Our contacts with other people shape our view of the world, reinforce our identity, and the interactions provide us with all kinds of opportunities and resources to get things done. The social capital associated with networks is also one of the primary ways facilitating crime. Therefore, the systematic analysis of criminal networks is considered a viable means to gain a more thorough understanding of criminal behavior. This paper is a general introduction to social network analysis (SNA) as an analytical tool for the study of adversary networks. The paper reviews some theoretical and key concepts, highlights functional applications, and presents a tentative protocol for data handling and coding. The discussion deals with some methodological issues, challenges and future developments in the field.

Longitudinal Linkages between Older and Younger Sibling Depressive Symptoms and Perceived Sibling Relationship Quality

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; M_age?=?12.34 years) and their older siblings (47% boys; M_age?=?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.

     

Retrenched,but Still Desired? Perceptions Regarding the Social Legitimacy of the Welfare State in Russia Compared with EU Countries

Abstract

This article explores how the retrenchment of the Russian welfare state has affected Russians’ attitudes towards it. Using European Social Survey data, we find that the retrenchment has not eroded Russians’ strong preference for a comprehensive system, despite their dissatisfaction with its outcomes. Further, we find that in Russia, some of the individual socioeconomic characteristics have a different effect on people's attitudes to social welfare compared to equivalent groups in EU countries. Overall, as in the EU, attitudes are multidimensional: a positive stance towards some aspects of the welfare state coexists with a critical approach towards others.     

Buffer or Brake? The Role of Sexuality-Specific Parenting in Adolescents’ Sexualized Media Consumption and Sexual Development

One main source of sexual socialization lies within family interactions. Especially sexuality-specific parenting may determine adolescents’ sexual development—adolescents’ sexual behavior and sexual risk behavior, sexualized media consumption and permissive sexual attitudes—to a significant extent, but different ideas exist about how this works. In this longitudinal study, we examined two hypotheses on how sexuality-specific parenting—parenting aimed specifically at children’s sexual attitudes and behaviors—relates to adolescents’ sexual development. A first buffer hypothesis states that parents’ instructive media discussions with their children—called instructive mediation—buffers the effect of sexualized media consumption on adolescents’ sexual attitudes and behavior and, vice versa, the effect of adolescents’ sexual attitudes and behavior on sexualized media consumption. A second brake hypothesis states that parents, by communicating love-and-respect oriented sexual norms, slow down adolescents’ development toward increased sexualized media use, permissive sexual attitudes, and sexual behavior and sexual risk behavior. Using four-wave longitudinal data from 514 Dutch adolescents aged 13–16 years (49.8% female), we found evidence to support a brake effect. More frequent parental communication of love-and-respect oriented sexual norms was associated with less permissive sexual attitudes and, for boys, with less advanced sexual behavior and a less rapid increase in sexual risk behavior. Parents’ instructive mediation regarding adolescents’ sexualized media consumption was associated with less permissive sexual attitudes at baseline, but only for girls. No systematic evidence emerged for a buffer effect of parents’ instructive mediation. In conclusion, although our data seem to suggest that parent–child communication about sex is oftentimes “after the fact”, we also find that more directive parental communication that conveys love-and-respect oriented sexual norms brake adolescents’ move toward sexual maturity.     

Valuation of natural resources: efficiency and equity

Adequate pricing of environmental goods is essential for the sustainable management of natural resources. It is not easy, however, to place a value on natural resources, because the excludability problem makes it difficult to protect natural resources from unpaid use and to exercise property rights over them. This article discusses the achievements and limitations of current natural-resource policies from the perspectives of efficiency and equity. It argues that a trust fund operating via market-based transactions is a promising approach to help to achieve simultaneously the goals of efficiency, sustainability, and poverty reduction, provided that property rights to the environmental resources are distributed fairly within current generations, as well as between present and future generations.

地方制度驱动的社区环境保护和自然资源管理——基于中国和泰国的多案例对比分析

近年来,以地方社区为主体的资源管理和环境保护的概念正日益受到重视。结合泰国北部和云南的多个案例,可以看到,以社区为主体的自然资源利用和环境保护模式,在平衡快速增长的经济发展需要与有限的生态系统承载力之间的矛盾发挥了积极作用;地方制度在激发个体参与到环境保护行动和资源管理中具有相应的潜力、局限,可形成一种机制。同时表明,建立在充足的社会资本、清晰的奖惩制度和强有力的执行机制之上的一套透明、公开、民主和灵活的地方制度,对激发成员有效参与集体环境保护、解决地方层面的资源冲突和促进可持续的自然资源管理有非常巨大的潜力。
