Witnessed community violence has been linked to a number of internalizing and externalizing problems in adolescents. Guided by Cicchetti and Lynch's (1993) ecological-transactional model, this study aimed to examine the impact that family-level factors had on negative outcomes associated with witnessed community violence. Using a nationally representative sample, we explored the moderational role of family cohesion in the relationship between witnessing community violence and delinquent behavior while taking demographic variables into account. Results from the investigation suggested that low levels of family cohesion were predictive of delinquency after controlling for race, gender, past delinquency, and direct trauma. In addition, the findings suggested that family cohesion moderated the impact of witnessed community violence on future delinquent behavior. Future directions for research and implications for practice were also discussed.  相似文献

Contrary to the expectations of secularization theory, religion remains socially important and affects politics in multiple ways—especially regarding conflict between religious communities. Theoretically, religion can increase altruism, but belief in the superiority of one's faith may facilitate intergroup discrimination and related conflict. Previous findings remain inconclusive, however, as specific religious ideas have hardly been tested. In this article, we argue that the content of religious ideas has causal effects on intergroup discrimination. We hence test the impact of two opposing, prominent religious ideas on altruism and discrimination: universal love and the notion of one true religion. Conducting dictator games with Christians and Muslims in Ghana and Tanzania, we find causal effects: Whereas the idea of one true religion increases intergroup discrimination, that of universal love fosters equal treatment. The policy implications hereof are obvious—promoting tolerant religious ideas seems crucial to avoiding conflict.  相似文献

Soy is often perceived as a typical example of a homogenous capitalist agricultural model that is responsible for ecological damage and social conflicts. But this monolithic perception of soy production can be challenged: more than 30 percent of the soy producers in Rio Grande do Sul (Brazil) are family farmers. In this contribution, we study soy production, the soy producers and their institutional environment from an actor-oriented perspective. We have uncovered different farming styles behind soy production: the colonial farmer, the niche farmer and the entrepreneurial farmer. The farming styles differ from each other not only in the farming system, but also in attitudes (for example, towards the forest). We found that the institutional environment and the technology are mainly focused on the entrepreneurial farmer. However, also, non-governmental organizations (NGOs) neglect the existence of small-scale soy producers. These results have several repercussions for further analysis of this problematic crop and how it can shift towards a more sustainable agricultural production model as small-scale farmers might produce soy more sustainably.  相似文献

Rural Kenyan households have different aspirations and income portfolio strategies, including agricultural intensification and income diversification. This article reports on a study that interviewed 624 households to explore rural aspirations and derive lessons for agricultural technology development and transfer. Though few households specialised in farming, many households self-identified as farmers and aspired to increase their agricultural income. Despite the prevalence of agricultural aspirations, few aspired for their children to have a future in farming. Combining aspirations with potential to invest, the article provides suggestions for targeting agricultural interventions. We need to start listening better to those people we call “farmers” to develop and offer innovations that meet their realities.  相似文献

This paper examines ten years (1963–1973) of visits to Australia of Italian Communist Party (PCI) officials. In particular, the visits' origins, meaning and ramifications are analysed and framed against the background of post‐war migrant worker identity discourses and radical politics. They appear to have shaped markedly the direction of the experience of Italian communists in Australia, especially in Sydney, and their interaction with both the Communist Party of Australia (CPA) and the PCI. Ultimately, they helped spread the message of Italian communism among migrants and encourage the replication on Australian soil of the successful experience of the Europe‐based PCI federations with thousands of worker members. For the CPA, which had been looking for new ways to break through to the hearts and minds of the migrant proletariat, the visits heralded a stronger partnership with its Italian members, a closer link with Eurocommunism, and a potential new stream of recruits that would have reversed the hemorrhaging of membership. The visits were instrumental, as argued in this paper, for the establishment and promotion of an Italian cultural and language space for which far‐left Italian migrants in Australia had long yearned.  相似文献

Although adolescence marks a vulnerable stage for peer influence on health behavior, little is known about the longitudinal and dynamic relationship between adolescent friendship and weight control. The current study aims to explain these dynamic processes among a sample of 1156 American adolescents in grades 9–11 (48.6% girls, 23.4% European American, 25.2% African American) from the National Longitudinal Study of Adolescent Health. Stochastic actor-oriented models were fit to examine changes in friendship networks and unhealthy weight control across two waves. The findings support a bidirectional relationship where weight control predicts future friendship seeking and friendship seeking predicts future weight control. The findings also indicate that adolescents prefer friends with similar weight control patterns. Taken together, the results of the current study indicate that adolescent friendships play an integral role in the development of unhealthy weight control and thus can be used to identify adolescents at risk and serve as targets within preventive interventions.  相似文献

We analyze, both theoretically and empirically, the influence of direct democratic institutions on the size and development of shadow economies. Our model suggests that, as the extent of direct democracy increases, implemented fiscal policies more nearly reflect the preferences of citizens and so reduce their incentives to operate in the informal sector. This theory implies a negative relationship between the extent of direct democracy and the size of the country’s shadow economy. We also theorize that direct democracy has a greater effect in reducing the informal sector when the former is at low or intermediate values and when the electoral system is characterized by a larger district magnitude. An empirical investigation of a sample of 57 democracies confirms our model’s predictions.  相似文献

In recent years it has been established that non-coding variants may be in linkage disequilibrium (LD) with coding variants up to several thousand base pairs away forming haplotype blocks. These non-coding markers may be haplotype specific and, therefore, informative regarding the surrounding coding sequence. In this study, we chose to study the VWA short tandem repeat (STR) as it is targeted in all major commercial kits utilized in routine forensic DNA profiling and is located in the von Willebrand Factor (vWF) gene; a gene associated with von Willebrand's Disease (vWD). We examined the VWA STR together with single nucleotide polymorphisms (SNPs) located throughout the vWF gene to identify haplotype structures and the extent of LD between markers in the region. Several areas exhibiting LD were identified by population data analysis in the 178 kilobase (178kb) vWF gene, which was supported by family studies. However, there appeared to be no evidence of LD blocks surrounding the VWA STR and evidence for recombination within 3 kb of VWA, hence, it is unlikely that VWA STR alleles could be used to predict haplotypes within the vWF gene that are associated with different forms of vWD.  相似文献
