One focus of agricultural development is climate smart agricultural technologies and practices (CSA). Development practitioners invest in scaling these to have wider impact. Ineffective targeting stymies CSA’s contribution to poverty reduction by excluding many of the poor and/or including those for whom agriculture is not a pathway out of poverty. This viewpoint proposes the need to recognise differentiated livelihood pathways within smallholder agriculture, linked to farmers’ differential capacity to engage in climate risk management. A farmer and livelihoods typology provides a framework to improved targeting of CSA and to identifying where alternative interventions, such as social protection, are more appropriate. 相似文献

评估性剥削人口贩运在全球的发案数是一项艰巨的任务,由于缺乏统一的措施以及可行的研究方法,关于人口贩运的实证研究非常缺乏,而了解性剥削的人口贩运活动对制定有效的反制措施具有至关重要的作用。根据针对目前已查明的人口贩运案件的深入挖掘和利用受害者收集的一手数据,本文试图提出基于外推法的评估全球性剥削人口贩运的发案数的可行策略。 相似文献

Purpose. There is widespread acceptance that sexual fantasy plays a role in sexual offences but little clarity as the nature of this relationship. This paper seeks to understand better the role of fantasy in offending behaviour through the study of sexual fantasy in Internet child pornography offenders when compared with contact offenders. Differences in the patterns of sexual fantasy associated with the different offender types are explored in order to understand how fantasy content is associated with contact offences with children and desisting from such direct acting out. Methods. Participants were all convicted of child sexual offences and recruited with the help of the probation and prison services. Out of these, 16 were Internet‐only offenders, 25 were contact offenders with no history of Internet offending and 10 were offenders with a mixed contact and Internet offending history. A variety of self‐completion questionnaires including fantasy were completed on an individual basis together with a detailed interview. Results. The most common sexual fantasies were typical adult‐male heterosexual fantasies though a variety of child‐oriented and other fantasies were also common. Contact offenders reported fewer girl‐oriented sexual fantasies although the groups did not differ in terms of terms of boy‐oriented fantasies. There was evidence that confrontational fantasies were commoner among contact offenders than Internet offenders. There are relationships between early sexual experiences and fantasy but peer sexual contacts seemed to be important rather than sexual abuse. Conclusion. Generally, the contact offenders seem to have less sexual fantasy pertinent to their offending than did Internet offenders. Fantasy deficit may be involved in contact offending against children. 相似文献

This paper describes and analyzes the structural and operational features of Chinese alien smuggling. Interviews with aliens, smugglers and law enforcement officials in China, Hong Kong and the U.S. reveal this activity to be a complex process comprising a number of distinct operational stages. Our data suggest Chinese alien smuggling groups vary in their level of organization but most are best understood as task forces, or small groups of people assembled to perform a particular piece of work. These task forces are typically linked to international social networks characterized by overlapping, dyadic relationships; a high level of role differentiation; and a limited degree of hierarchy. Such groups are highly responsive to changing socio-legal and market constraints.The study was supported in part by a grant from California State University. The authors are grateful to John Galliher for his comments and suggestions, and would like to thank Jorge Guzman and Darwin Chen of the U.S. INS for their assistance with the project. An earlier version of this paper was presented at the annual meeting of the American Society of Criminology, Miami, 1994. 相似文献

On 27 October 2005, the first Iranian satellite—Sinah-1—was launched. The satellite failed soon after launch, but it represented a significant technological step by the Islamic Republic, and was also a statement of intent on behalf of Iranian space ambitions. Current and projected Iranian space capabilities are highly dependent upon foreign technologies and expertise, but the Iranian nuclear and ballistic missile programmes offer a glimpse of how Iran's space programme may yet develop. This essay provides an overview of Iranian space capabilities, and places it within contemporary Iranian domestic and strategic contexts. It also offers an insight into how Iran's space programme is organized, and lastly, offers a view on how best the United States might influence Iran's space programme. 相似文献
