Many technologies have both vital legitimate uses and potent military applications. An international regulatory regime has been devised for the purpose of monitoring the use of the most dangerous of these technologies, namely chemical, biological and nuclear weapons. Multiple examples of the use of chemical and biological weapons against members of the public, and evidence of prohibited state weapons development programs, demonstrate the vital need for a more effective enforcement regime. The authors discuss the concept and threat of dual‐use technology, the existing regulatory regime and its shortcomings, and propose enhancing this regime with powerful international judicial authorities to enable the prosecution of any state, group or individual who attempts to misuse dual‐use technology.  相似文献

Archaeological analyses of faunal assemblages often rely on rationale derived from the prey choice model to explain temporal and spatial changes in taxonomic measures of diversity and/or abundances. In this paper, we present analyses of ethnoarchaeological observations and bone assemblages created by Central African Bofi and Aka forest foragers which show that different small prey hunting technologies target specific suites of prey and that hunters vary their technological choice depending on their foraging goals. Analysis of ethnoarchaeological bone assemblages produced by the Bofi and Aka shows that variability in target prey can create spatially distinct, but contemporaneous, faunal assemblages with different diversity values and abundance indices. These data reveal important variation in how individuals within a contemporary human population rank prey and challenge current assumptions about the meaning of diversity and abundances measures in archaeological contexts. We argue that the use of diversity and abundance indices can obscure important intrasite variability in prehistoric foraging effort and suggest strategies that might enhance current techniques.  相似文献

Stone tool manufacture by many prehistoric and recent societies was characterized by deliberate heating of fine grained siliceous rocks to improve their flaking properties. Extensive mechanical testing of heated and unheated cryptocrystalline and macrocrystalline quartz lithologies has shown that thermal treatment causes a consistent marked reduction in fracture toughness. This mechanical property can be used as an objective measurement of the flaking qualities of stone materials, and a reliable criterion for the recognition of intentionally heated artefacts in the archaeological record. X-ray diffraction studies and scanning electron microscopy have demonstrated that the change in fracture toughness with heating is the result of recrystallization. The poorly ordered, strongly interlocking cryptocrystalline fabric of the unheated samples becomes more equigranular and better crystallized with thermal treatment. As a consequence, fractures propagate more readily in heated samples, accounting for their better flaking properties.  相似文献

How did the Arctic seabed become a political space despite its almost complete inaccessibility to humans? While we can explain the causes of this in geopolitical and economic terms, theorizing the process is more difficult. This article argues that spatial constructions of the Arctic seabed emerge from the interaction among human actors, technologies, and the material environment. This interaction generates representations which are then fed into the overall process of spatializing the seabed. By highlighting the role of technology, this paper offers a way of relating human agency and materiality in the construction of oceanic space. The case study of bathymetry in the ongoing disputes over the Arctic continental shelf illustrates how technological and scientific advancements are embedded into global politics and themselves cause evolutions in the spatial construction of the seabed.  相似文献

ABSTRACT

For over a millennium, Catholic and Protestant traditions have deployed technologies to address the central paradox of the Christian faith: God’s absence after Easter. The following essay brings together scholarship on religious technics in the Christian Latin West during the medieval and early modern periods with a focus on the performance of presence. Medieval actors utilized an array of techniques, instruments, and contraptions to manifest the divine power present in holy matter. The movement of artifacts and people across medieval and early modern horizons mobilized and multiplied the effects of sacred proximity. The Society of Jesus’ emphasis on sensuality in worship and spectacle linked older forms of ritual piety with routinized religion. The shift from a predominantly Christian to modern culture in the West did not terminate organized religion’s close association with technology, but extended the experience of spiritual presence in the West through industrial and post-industrial, digital means.  相似文献

空间信息技术近年来在文化遗产保护领域发挥了巨大的作用,在大遗址、运河遗产、长城资源等文化遗产调查、保护和管理中得到了广泛的应用.茶马古道作为特殊的线性文化遗产,所经之处受自然环境和地理条件的影响,对其保护和调查都存在很大的难度.而空间信息技术由于其全天时、全天候、覆盖范围广、信息化程度高、不需要人亲临现场的特点,在文化资源调查和管理中发挥巨大的作用,可以适应这一特殊要求.本文通过对茶马古道在保护和规划中对空间信息技术的需求进行了分析,探讨了空间信息技术在茶马古道文化遗产资源的调查、保护、规划及管理中的应用.  相似文献

In France, during the Restoration, various attempts at industrial modernization were made. One of these consisted in the circulation of technical ideas through industrial exhibitions and the technical press, the latter channel being represented by treatises, manuals, dictionaries and technological journals. One of the first of these journals was the Annales de l’industrie. This paper considers two aspects. First, the institutional environment: the French tradition of technological writing, the national industrial exhibitions, the legacy of the école centrale experiment, and the influence of the Parisian Royal Academic Society of Sciences. Second, an analysis of the contents of the journal is the occasion for a discussion of technological progress on the level of the traditional arts and crafts, the dominant mode of industrial production during the 1820s. Other themes discussed are the avoidance of scientific terminology, official innovation policy, Great Britain as the model to be emulated, and the tension between apprenticeship and modern technical education.  相似文献
