Economic strengthening interventions may increase income, assets, and food security. Donors and implementers see the potential for improvements in child well-being. This article presents lessons learnt from the implementation of two economic strengthening interventions. It finds missed opportunities with regard to child nutrition, and recommends: (1) integrating economic strengthening interventions with complementary development activities; (2) deep formative assessment to inform programme design; and (3) the use of community-based feedback loops. Development practitioners, funders, policymakers, and researchers must take every opportunity to improve the lives of children as young as possible to build healthy families, communities, and nations.  相似文献

The authors draw on a natural experiment to demonstrate that states can reconstruct conflictual interethnic relationships into cooperative relationships in relatively short periods of time. The article examines differences in how the gentile population in each of two neighboring territories in Romania treated its Jewish population during the Holocaust. These territories had been part of tsarist Russia and subject to state-sponsored anti-Semitism until 1917. During the interwar period one territory became part of Romania, which continued anti-Semitic policies, and the other became part of the Soviet Union, which pursued an inclusive nationality policy, fighting against inherited anti-Semitism and working to integrate its Jews. Both territories were then reunited under Romanian administration during World War II, when Romania began to destroy its Jewish population. The authors demonstrate that, despite a uniform Romanian state presence during the Holocaust that encouraged gentiles to victimize Jews, the civilian population in the area that had been part of the Soviet Union was less likely to harm and more likely to aid Jews as compared with the region that had been part of Romania. Their evidence suggests that the state construction of interethnic relationships can become internalized by civilians and outlive the life of the state itself.  相似文献

Despite increased attention to gender issues in the international development arena since the rise of feminism in the 1970s, few agricultural research organisations have integrated gender in their problem diagnosis and technology development. Gender mainstreaming can significantly enhance the impact of research and technology development. Entrenching gender mainstreaming in organisations and their research agendas remains a challenge. To overcome it requires political will, accountability, a change in organisational culture, and technical capacity within an organisation. This article presents an experience of gender-mainstreaming practice in the institutional culture and agricultural research processes by Urban Harvest and the International Potato Centre (CIP).  相似文献

Fracture matches are considered the strongest conclusion in the forensic examination of rigid materials, such as glass, metal, and paint. However, publications that support the fracture matching of polymeric films, such as tape backings, are limited. This study was designed to determine the validity and error rate associated with conducting end-match (fracture match) examinations on vinyl electrical tape. Test designs varied the source roll of tape, test preparer, or mode of separation from the roll. Results indicated that each affected the resulting severed tape ends. The analysts examining the end matches also had an effect on the results. Eight end matches in the study were not identified by the initial analysts and were considered inconclusive. One end match was misidentified, resulting in one false positive and an error rate of 0.049%. These results support a comprehensive physical and chemical tape comparison regardless of indications of an end match.  相似文献

This article responds to recent calls for a focus on successful development in young people and examination of its developmental precursors, in order to identify potentially modifiable targets for interventions. The current study examined child and adolescent precursors of positive functioning in emerging adulthood, including individual characteristics, relationship factors, and connections to the community, using a multidimensional positive development measure at 19–20 years. The sample consisted of 511 males and 647 females who were participants in the Australian Temperament Project, a population based longitudinal study that has followed young people’s psychosocial adjustment from infancy to early adulthood. Higher levels of positive development in emerging adulthood were associated with stronger family and peer relationships, better adjustment to the school setting, higher family socioeconomic status, and better emotional control. Some significant gender differences were observed, with emotional control, family relationships, and community orientation all being stronger predictors of males’ than of females’ positive development. The findings provide possible targets for child and adolescent interventions to promote positive development in early adulthood.  相似文献
