The eradication of child undernutrition and extreme poverty are important objectives for most societies. Countries with higher national incomes usually improve in both dimensions, but not always at the same rate. Using quantile regression, we show that poverty rates tend to decline with increased income at a roughly constant elasticity. In contrast, while the prevalence of child wasting declines at that same elasticity where it is most widespread, the elasticity becomes smaller as wasting becomes less prevalent. This finding suggests a greater need for increasingly targeted interventions to achieve a given reduction in undernutrition as its prevalence declines.  相似文献

For most of its history the United Nations was reluctant to deal with intelligence and major powers were reluctant to share intelligence with it. But as the UN's peacekeeping operations intensified in some of the world's hot spots in the early 1990s, the UN found it both necessary and wise to create an information analysis capability at UN headquarters in New York. To funnel selected intelligence to the headquarters, several countries (including the US, UK, France and Russia) loaned intelligence officers to the UN's Situation Centre on a secondment basis. This paper describes the activities of the SitCen's Information and Research (I&R) Unit that existed from 1993 to 1999 under the informal motto ‘Keeping an Eye on the World’. Using a case study of I&R reporting on the situation in Eastern Zaire (1996), where UN-run refugee camps were under attack, it is possible to examine the nature and utility of the intelligence provided by the intelligence officers to UN decision-makers and the planners of the Canadian-led multinational force in the region. It reveals that the Unit provided significant and useful intelligence about arms shipments, belligerent activities, and the status of refugees and made several prescient predictions and warnings. The Unit sought to minimize national bias and incomplete information, though both problems were still in evidence. Still, in many ways, the I&R Unit remains a useful model for the development of a future intelligence capability.  相似文献

The 1974 Cypriot War divided the island of Cyprus into two parts with a narrow demilitarized zone (DMZ) between the opposing Greek Cypriot and Turkish forces. The volatility and violence in this zone, called the ‘Green Line’, necessitated a constant UN peacekeeping presence that was achieved mainly with manned observation posts (OPs). About 150 of these posts were established by 1975 to maintain stability and prevent flare-ups, including any lethal exchanges between the two sides. By the early 1990s, many of the countries contributing peacekeepers to the United Nations Peacekeeping Force in Cyprus (UNFICYP) had become tired of the stalemate and the lack of progress in negotiations (peacemaking), so they withdrew their troops from the force. This necessitated a reduction in the number of constantly manned OPs from 51 in 1992 to 21 in mid-1993. Further downsizing of UNFICYP by the UN Security Council in 2004 gave rise to a new approach to monitor the DMZ and produce actionable intelligence. Cameras were installed in hot-spots in the Nicosia DMZ and more responsive patrols were introduced as part of the new ‘concentration with mobility’ concept. This was the first time a UN peace operation used unattended cameras to monitor a demilitarized zone. This article examines the UN's difficulties and successes using the remote cameras, especially during important incidents. Other technologies that aided UNFICYP are also reviewed for lessons that might assist an under-equipped United Nations in its watchkeeping function.  相似文献
