On January 2, 2009, the 2001 UNESCO Convention on the Protection of the Underwater Cultural Heritage entered into force, setting an international precedent for the protection and preservation of underwater archaeological resources and providing guidelines for site management and responsible investigation. Historically, submerged cultural resources, particularly shipwrecks, have been exploited primarily for their potential monetary value. Over the last 50 years archaeologists have challenged this perception, demonstrating the cultural and scientific value of submerged cultural resources.  相似文献

The key problem restricting lithic microwear analysis is the lack of quantitative analysis to support qualitative assessments of different wear traces. This paper presents the reflective laser scanning confocal microscope (LSCM) as a new technique for the study of lithic microwear that has the potential to resolve this problem. Firstly, an example is presented that shows how the LSCM compares with conventional reflected light microscopy and scanning electron microscopy. This shows that images, rivalling that of the SEM, can be produced in similar timescales to conventional photomicrography and with no need for casting or sample preparation. The LSCM is also used to measure surface roughness of use-wear produced from working hide (dry, fresh and greasy), woodworking and antler working. This analysis demonstrates clear differences between the different wear polishes and the potential of the LSCM as a quantitative approach in lithic microwear research.  相似文献

There has been a widespread recovery of public memory of the events of the Second World War since the end of the 1980s, with war crimes trials, restitution actions, monuments and memorials to the victims of Nazism appearing in many countries. This has inevitably involved historians being called upon to act as expert witnesses in legal actions, yet there has been little discussion of the problems that this poses for them. The French historian Henry Rousso has argued that this confuses memory with history. In the aftermath of the Second World War, judicial investigations unearthed a mass of historical documentation. Historians used this, and further researches, from the 1960s onwards to develop their own ideas and interpretations. But since the early 1990s there has been a judicialization of history, in which historians and their work have been forced into the service of moral and legal forms of judgment which are alien to the historical enterprise and do violence to the subleties and nuances of the historian's search for truth. This reflects Rousso's perhaps rather simplistically scientistic view of the historian's enterprise; yet his arguments are powerful and should be taken seriously by any historian considering involvement in a law case; they also have a wider implication for the moralization of the history of the Second World War, which is now dominated by categories such as "perpetrator,""victim," and "bystander" that are legal rather than historical in origin. The article concludes by suggesting that while historians who testify in war crimes trials should confine themselves to elucidating the historical context, and not become involved in judging whether an individual was guilty or otherwise of a crime, it remains legitimate to offer expert opinion, as the author of the article has done, in a legal action that turns on the research and writing of history itself.  相似文献

This article explores a series of Carolingian historians, writing in the early ninth century, who marginalized the role of God’s agency, in sharp contrast to the pattern established by the Annales Regni Francorum. Where this has been noted before, largely in relation to Einhard’s Vita Karoli, it has been explained either as a clash between lay and monastic ideals or as a by-product of the classical renewal at the Carolingian court. Examining this process across multiple texts suggests, however, that these historians can be understood as self-consciously ‘secularizing’ in response to contemporary crises.  相似文献

The notion of transformation is gaining traction in contemporary sustainability debates. New ways of theorising and supporting transformations are emerging and, so the argument goes, opening exciting spaces to (re)imagine and (re)structure radically different futures. Yet, questions remain about how the term is being translated from an academic concept into an assemblage of normative policies and practices, and how this process might shape social, political, and environmental change. Motivated by these questions, we identify five latent risks associated with discourse that frames transformation as apolitical and/or inevitable. We refer to these risks as the dark side of transformation. While we cannot predict the future of radical transformations towards sustainability, we suggest that scientists, policymakers, and practitioners need to consider such change in more inherently plural and political ways.  相似文献

This paper reviews the evolution of palaeoglaciological reconstructions in regions at the periphery of glacierization, where an improved understanding of the role of glacial thermal regime has helped refine the delimitation of ice sheet maxima. Also significant has been the recognition in numerical models that some areas, especially ice sheet marginal zones, are subject to short periods of ice occupancy and hence that glacial landsystem signatures can be extremely subtle. This is compounded wherever cold-based conditions dominate during early stages of ice sheet recession, giving rise to a landform imprint typical of peripheral regions and hence often misinterpreted as unglaciated or glaciated only by older glaciations. Subtle landform imprints include meltwater channels, thin glacigenic veneers or scattered erratics and modified tors. More substantial glacigenic landform-sediment assemblages (‘drift belts’) do not always represent ice sheet maxima but instead may record significant changes in thermal regime, possibly linked to periods of ice-marginal stabilization. Some upland areas that lie beyond the traditionally demarcated limits of glaciation (e.g. Dartmoor in SW England) may contain subtle evidence of satellite ice cap development which has been overlooked due to the strong periglacial landform signature.  相似文献

Although women’s land rights are often affirmed unequivocally in constitutions and international human rights conventions in many African countries, customary practices usually prevail on the ground and often deny women’s land inheritance. Yet land inheritance often goes unnoticed in wider policy and development initiatives to promote women’s equal access to land. This article draws on feminist ethnographic research among the Serer ethnic group in two contrasting rural communities in Senegal. Through analysis of land governance, power relations and ‘technologies of the self’, this article shows how land inheritance rights are contingent on the specific effects of intersectionality in particular places. The contradictions of legal pluralism, greater adherence to Islam and decentralisation led to greater application of patrilineal inheritance practices. Gender, religion and ethnicity intersected with individuals’ marital position, status, generation and socio-ecological change to constrain land inheritance rights for women, particularly daughters, and widows who had been in polygamous unions and who remarried. Although some women were aware that they were legally entitled to inherit a share of the land, they tended not to ‘demand their rights’. In participatory workshops, micro-scale shifts in women’s and men’s positionings reveal a recognition of the gender discriminatory nature of customary and Islamic laws and a desire to ‘change with the times’. While the effects of ‘reverse’ discourses are ambiguous and potentially reinforce prevailing patriarchal power regimes, ‘counter’ discourses, which emerged in participatory spaces, may challenge customary practices and move closer to a rights-based approach to gender equality and women’s land inheritance.  相似文献

The separation of powers often makes it difficult to understand who is responsible for legislative outcomes. Both members of Congress and presidents seek to shape perceptions of policy responsibility to their advantage. Yet, the relative size of the president's rhetorical stage gives him disproportionate influence in molding these discussions at critical moments. Given these circumstances, how, when, and why, do presidents claim credit for themselves and attribute credit to members of Congress for legislation? Using an original dataset based upon a content analysis of all presidential signing statements from 1985–2008, we find that presidential strategies to claim and attribute credit for laws are greatly impacted by both political context (approval, divided government, midterm elections, and party power) and bill-specific attributes (appropriations, salience, and veto threats). The theory and results highlight the importance of taking multiple institutions into account when thinking about credit.  相似文献
