Among peace researchers and practitioners, it is generally accepted that efforts to prevent violence can be instrumental in its mitigation. So, it was distressing to read the research findings of Meier, Bond, and Bond (2007) that mitigation was positively related to organized raids in the Horn of Africa where there is pastoralist–pastoralist and pastoralist–agriculturalist violence. This article seeks to build on their research. It uses a ‘de-trending’ approach for time-series analysis that is commonly used in economics and financial studies. It reports an opposite statistically significant finding. When the data used by Meier et al. are de-trended, violence associated with organized raids is negatively correlated with mitigation. This negative correlation is similar when data on mitigation and organized raids are de-trended with time as a predictor, on the one hand, and with seasonality over time as a predictor, on the other. Implications regarding the temporal dimension of peace research and practice are presented. 相似文献

ABSTRACT On a sample of U.S. urbanized areas in 2000, we test theoretical hypotheses of the effect of land‐use controls on the spatial size of urban areas. We find that minimum lot‐size zoning and maximum FAR restrictions expand the urban area, while maximum lot‐size zoning, urban growth boundaries, minimum square footage limits, maximum building permit restrictions, minimum person per room controls, and impact fees contract the urban area. All of these findings are consistent with theoretical predictions although the effect of urban growth boundaries and minimum square footage limits are not statistically significant. 相似文献

Despite rapid economic growth and massive inflows of aid, rural poverty in Mozambique is worsening. Agricultural production and productivity have not increased in the last decade. Use of chemical fertilizers and other modern technology is at a low level and decreasing. The present development model emphasizes that the role of government and donors is to provide human capital and infrastructure, while the private sector is responsible for economic development and ending poverty. The most recent national surveys confirm what is being seen elsewhere in Africa — that this non‐interventionist strategy does not raise agricultural productivity or reduce poverty. While 80 per cent of Mozambique's population is engaged in agriculture, this sector contributes only 20 per cent of GDP. This suggests that investments in agriculture are likely to generate pro‐poor growth, both to rural and urban dwellers. This policy failure is increasingly recognized, but donors and government have invested too much political capital in the current policy to change easily. 相似文献

This paper aims to characterise the varying magnitudes of landscape disturbance across the WWI battlefield of Verdun, France. Five study sites were surveyed to best reflect the varying degrees of disturbance under common similar environmental characteristics, e.g. bedrock, soil type and topographic position. Disturbance magnitude was determined by counting and measuring the dimensional attributes of craters in two 0.25 hectare plots at each of the five study sites. Additionally, a survey of microtopography was performed at each of the five study sites to record changes in elevation of damaged sites. The spatial character and variation in the magnitude of disturbance at the five disturbance study sites was linked to four variables: (1) location of armies in relation to the front; (2) stagnation of front lines; (3) topographic location of armies; and (4) geologic characteristics of the site. 相似文献

This paper reports the results of the excavation of an Early Bronze Age cist cemetery on the mid-Northumberland coast at Howick. The Bronze Age site was discovered during the investigation of a Mesolithic hut site, the latter having been published separately as a monograph. A total of five cists were found with only one being adult-sized, the rest presumably for infants. Due to the acidic conditions on the site, only a few fragments of a small skull were found in Cist 2. Other small finds included a small sherd of Food Vessel urn in an area of disturbance next to Cist 5, smoothed limestone cobbles and some nodules of yellow ochre. Flints were found in most of the feature fills, but these are considered to be residual as they are directly comparable to the narrow blade material found within the Mesolithic hut and its environs. The siting of Early Bronze Age cist burials in coastal locations is thought to reflect contemporary settlement on the coastal margin and its hinterland. With no Bronze Age dwelling sites known from this area, these cemeteries have an added significance as they provide indirect evidence for Bronze Age settlement on the North-East coastal plain. 相似文献
