Many factors governed the penetration efficacy of prehistoric projectile weaponry. Archaeologists broadly focus their efforts on understanding the effect of stone weapon tips because these specimens are often the only part of the weapon system that survives in the archaeological record. The tip cross-sectional area (TCSA) and perimeter (TCSP) of stone weapon tips have been shown to correlate with target penetration depth. Here, using results from both static and dynamic penetration testing, we compare TCSA and TCSP against other tip geometry metrics: lateral surface area (LSA) and volume (V). Our analyses broadly show that using a single-point geometry metric evaluated at multiple locations along the length of the point, or using multiple geometry metrics evaluated at a single location, better predicts required energy than using a single-point geometry metric evaluated at a single location. Our results also show that in the case where a single geometry metric evaluated at multiple locations is used LSA provided the most robust prediction models. Finally, our results show that for the case where all geometry metrics evaluated at a single location are used the location that provides the most robust prediction model is dependent on how far the point penetrated the target.  相似文献

By the 1880s, imperial government's practice of ‘retreating’ to the Indian hill stations for much of the year was well established. Despite the strength of this new tradition, such a relocation of colonial administration never lacked its critics. This paper examines the expanding administrative use of the hill stations from the early nineteenth century through the 1880s. As the nineteenth century ‘scientific’ framework for British control of India was formed, conflicting strategies and practices for maintaining imperial control required mediation and contrasting frameworks for defining duty and loyalty between government and subject vied for dominance. The significance of Utilitarian thought, changing appraisals of climate and constructions of race are evaluated in an analysis of the imperial hill stations.  相似文献

What did peasants discuss at party meetings? Were they mobilized by ethnic politics or indifferent to them altogether? The end of the First World War brought about universal male suffrage in much of Europe, and with it the process of mass politics began. The concept of national indifference is important in understanding interwar politics, because this period is often studied teleologically with attention focused on extremism and nationalism as the primary mobilizing issue

Agrarian movements have been under-researched, and when Agrarians have been studied, it has been through the prism of elite politics. This comparative paper seeks to redress this omission by looking at grassroots rural politics. The interwar countryside was marked by profound political, economic and social transformation but also in terms of what Robert Paxton has described as the ‘triple crisis of the countryside’ – worsening economic conditions, the declining status of the countryside and inadequate political representation. The paper will explore how reform and crisis impacted how agrarian politics functioned at a local level by asymmetrically comparing cases from Romania, Poland and Ireland, with the final case helping to contextualize Eastern Europe within the wider European experience This paper argues that the rural population was mobilized, but primarily in the context of local issues rather than national ethno-political questions. Local party organization was, to paraphrase James C Scott, the site ‘of an exchange of small arms fire’ in rural class conflict, as questions regarding the control of public space, generational conflict and power within the village mobilized peasants. Thus, I argue that it was the underlying socio-economic issues that mobilized the rural population, not nationalism. The dynamics of these conflicts were shaped by local economic, political and social power dynamics, and by using indifference as a concept, we can look more deeply at interwar politics from a grassroots perspective and develop a more nuanced understanding of local, national and European politics.  相似文献
