Footwear impressions are one of the most common forms of evidence to be found at a crime scene, and can potentially offer the investigator a wealth of intelligence. Our aim is to highlight a new and improved technique for the recovery of footwear impressions, using three-dimensional structured light scanning. Results from this preliminary study demonstrate that this new approach is non-destructive, safe to use and is fast, reliable and accurate. Further, since this is a digital method, there is also the option of digital comparison between items of footwear and footwear impressions, and an increased ability to share recovered footwear impressions between forensic staff thus speeding up the investigation. 相似文献

AbstractGiven North Korea’s desire to maintain nuclear weapons—and barring its unexpected collapse—how can the US and its allies establish and maintain a peaceful Northeast Asia? Current US policy alternatives do not offer an effective means for removing North Korean nuclear weapons without creating many more serious problems that jeopardize a stable future for Northeast Asia. However, by engaging in foreign direct investment (FDI) through North Korea’s special economic zones, the United States and other nations can engage North Koreans at all levels of society and build a future environment of cooperation and stability. Such a long-term engagement policy will prove more successful than isolation, sanctions, or military force, and will bolster regional actors’ efforts to develop additional stability-inducing policies. 相似文献

The paper examines the theoretical and empirical debates surrounding the benefits of an export‐led growth strategy. The experience of two newly industrialised countries are analyzed and discussed in relation to South Africa's political and economic position. The writers attempt to show that an uncritical acceptance of ‘recipes’ for economic development, which do not take into account specific domestic political and economic factors, could lead to inappropriate policy formulation and implementation. 相似文献

In today's knowledge-based societies, understanding basic scientific concepts and the capacity to structure and solve scientific questions is more critical than ever. Accordingly, in this article we test an innovative methodology for teaching science and environment in public primary schools where traditional (teacher-centred) teaching was replaced with student-centred activities using LEGO kits. We document positive and significant improvements of 0.18 standard deviations in standardised test scores. Such positive results are mainly concentrated within boys that were located above the median of baseline academic performance. 相似文献

This article examines the ideological roots and historical development of an early radical economic egalitarian tradition in American political thought. It concentrates on a group of thinkers and social critics that were active from the 1820s through the beginning of the Civil War. Inspired by republican themes, they forged a radical critique of the emerging capitalist order and a skepticism of economic modernity. By reworking the republican political notion of an equality of social relations as an essential context for individual liberty, these radical critics posed a challenge to the emerging capitalist order. They would also be unique in the way that they analyzed the workings of this new economic system arguing that it was a mechanism that would systematically reproduce economic inequality eroding republican forms of government and society making them a distinct voice in America's egalitarian tradition. 相似文献
