Summary. No consideration has ever been given to the possibility that women may have had a part in the execution of European Upper Palaeolithic art; however, an examination of the history of research in this field suggests that preconceptions, prejudice, and the acceptance of unproved theories have perhaps been responsible for the view that it was a male-only activity.
Some of its so-called 'religious' aspects are reconsidered, and re-explained from a female perspective in the light of an experimental attempt to reproduce Palaeolithic plaques with superimpositions. The results of this experiment suggest that Palaeolithic art may well have been multipurpose, at least some being illustrative and part of a general visual communication system — perhaps a forerunner of written communication. It seems probable that all members of society, especially women, were involved.  相似文献

Optical coherence tomography (OCT), a new method for ceramics research, is a nondestructive, three‐dimensional tomography system, which provides subsurface morphology visualization of samples based on the refractive index or dielectric constant differences in the target specimen. In this study, seven shards from different Chinese kilns of Song and Yuan dynasties (10–14th centuries) were scanned to visualize the subsurface morphology of their glazes. The images revealed unique phase assemblage modes in different samples. The results suggest OCT may be used to identify ceramics and provide information about their manufacturing technology.  相似文献

This paper reviews twenty years progress in the study of gender in Third World development and the extent to which gender has been incorporated within mainstream development theory and practice. Special reference is made to the role geography has played in this arena. It is argued that while gender as a theoretical framework for explaining women's differential but continued subordination should be reaching maturity, there has been little attempt to formulate cohesive models which integrate micro-and macro-level concepts and which could provide a firm base for future theory-building. More important, studies of gender in the Third World development have seldom addressed the question of development policy or put forward practical solutions for the integration of gender issues in development planning. As a case study of gender in development planning the paper examines the Australian Government's women in development (WID) policy, the ways in which it was informed, and the extent to which it has been implemented.  相似文献

This article surveys current security challenges and identifies obstacles to effective global and regional responses and cooperation in an era when security has become increasingly divisible. The new situation is partly explained by the complexity and variety of security challenges, both traditional and new, and by the linkages between them. It argues that a new pattern of improvised, ad hoc and often case‐specific security mechanisms has developed, which it calls Collective Conflict Management (CCM). The argument is illustrated by reference to cases of CCM where a wide range of actors—multilateral institutions at the global and regional levels, individual states or ad hoc coalitions, professional and commercial bodies, and non‐governmental organizations—collaborate in an effort to manage specific security threats and challenges, bringing together a variety of relationships, resources and skills. The urge for collective action, rather than unilateral or single actor‐led, is motivated by a number of factors and ‘drivers”, not all of them necessarily positive or constructive. The article concludes that the success or failure of CCM will depend in part on the severity of the problems it faces and in part on the motives and incentives behind collective responses. This new pattern raises interesting and important questions for the future of international security. While CCM may be untidy and lack clear norms and standards, in many cases it may be the best available in an increasingly fractured world.  相似文献
