This paper explores the functioning of coastal societies against the background of the changing role of coastal ‘contact zones’ on both sides of the Channel and southern North Sea region, between AD 600 and 1100. In so doing, it reassesses aspects of the generalising frameworks of interpretation applied over the past quarter of a century in favour of a more contextual approach, enabled by long known (although sometimes forgotten) and recent archaeological discoveries, together with new geological research. Regional and local complexity is a recurrent feature. A revolutionary increase in our awareness of the extent to which marginal coastal landscapes were occupied and exploited is matched by a commensurate increase in our knowledge of the number and complexity of settlements and seasonally used sites, involved in maritime exchange networks. Ultimately, this contribution confronts the dynamism of regional coastal societies with the wider socio-political structures in which they were incorporated.

A key feature of stone artefact morphology is the arrangement and patterning of negative flake scars left on flakes and cores. Scar patterning is often treated as a rough guide to identifying methods of core preparation and reduction and usually forms a key component of lithic typologies and other systems of analysis. However, scar patterns are often complex and difficult to capture using traditional measurement or classificatory techniques, particularly where flakes are thick and irregular, or where cores are flaked on many sides from a number of platforms. Three-dimensional analysis of flake scars is now more feasible using digital 3D surface scanning technologies, or using three-dimensional measurement tools such as the Microscribe-3DX which is now widely used in biological geometric morphometric studies more generally [D.C. Adams, F.J. Rohlf, D.E. Slice, Ital. J. Zool., 71 (2004) 5–16; F.J. Rohlf, L.F. Marcus, Trends Ecol. Evol. 8 (1993) 129–132. [1 and 34]]. This paper develops a mathematical formula for describing scar patterning using vectors calculated from the start and end points of flake scars recorded in three dimensions.  相似文献

This paper examines evidence for the origin of the tree Spondias mombin in Africa, where it is generally described as introduced from the Neotropics. Based on biogeographical, ecological, and historical evidence, this paper argues that the tree reached Africa via natural, long-distance dispersal, and should be considered an African native plant. The idea that it is introduced appeared in 1868, when it was a scientifically justifiable conclusion reflecting the limitations of nineteenth-century biogeographical knowledge. By the early twentieth century, representing Spondias mombin as a human introduction in Africa was no longer scientifically justifiable because of advances in knowledge of the African flora and plant dispersal ecology. Nonetheless, most authors continued to represent the tree as introduced, in part because such representation was consonant with dominant images of the African environment: (a) that the continent had suffered extensive deforestation in the recent past, and (b) that Africa's flora was depauperate in fruit trees prior to the coming of Europeans. Recent authors continue to describe Spondias mombin as introduced because they have not sufficiently considered the historic contexts of primary and secondary sources on Neotropical plant introductions in Africa. This paper concludes that the human role in creating the African portion of the trans-Atlantic tropical flora has been overemphasized. Natural plant dispersal across the Atlantic may be more frequent than generally accepted.  相似文献

This paper takes as its focus the practical solutions and new ways of thinking being forwarded by women across Europe under the umbrella of EuroFEM. It sets these case studies in the context of the developing importance of the ‘everyday life concept’. This concept has grown from two routes, firstly, feminist concerns for the way in which much of women's time is spent attempting to overcome the separation of home, waged work, the market and public institutions, secondly, arising out of stmcturation theory, the discussion of the opportunity/constraint negotiation through which life is lived and the possibility of public policy enhancing survival and coping strategies. The paper goes on to ask how these ways of thinking about daily life can be mainstreamed.

The paper draws upon research currently funded under the fourth action programme of equal opportunities for women and men.  相似文献

This paper develops an argument for the agency of objects, looking at the effects objects have on people. Groups of related objects, such as pots or metal ornaments, create stylistic universes which affect producers and users of new objects, bound by the canons of style. For an object to be socially powerful in a recognized manner, the form of the object lays down certain rules of use which influence the sensory and emotional impacts of the object. Formal properties of artifacts are influenced by the genealogy of the object class, including historical continuities and changes, and also its perceived source. The forms of objects, the historical trajectories of the class of objects and their perceived sources combine to have social effects on people, shaping people as socially effective entities. Britain’s incorporation into the Roman Empire between 150 BC and AD 200 provides an excellent case study through which to look at the changing corpora of objects, which had continuities and changes in form, a set of subtle attributions of sources and a complex range of social effects.  相似文献

I argue here that the articles in this forum contain basic agreements. All three reject naturalism, reductionism, and monism while retaining causality as an explanatory category, and all three emphasize the role of time and argue for a view in which culture is regarded as both structured and contingent.
The differences among the explanatory proposals of Hall, Biernacki, and Kane are as important as the similarities: while Hall favors a Weberian approach, Biernacki argues for a primarily pragmatic explanation of culture, and Kane for a primarily semiotic explanation. I argue that all three positions face immanent problems in elucidating the exact nature of cultural explanation. While Hall leaves the problem of "extrinsic" ideal-typical explanation unsolved, Biernacki simply presupposes the superiority of pragmatic over other types of cultural explanation, and Kane does the same for semiotic explanation. Hints at cultural explanation in the form of narrative remain underargued and are built on old ideas of an opposition between "analysis" and "narrative." This is also the case with the latest plea for "analytic narratves." I conclude that a renewed reflection on this opposition is called for in order to come to grips with cultural explanation and to get beyond the old stereotypes regarding the relationship between historical and social-scientific approaches to the past.  相似文献

The Social Exclusion Unit (SEU) of the British Government is a recent and innovative response to social problems in the UK. Through an examination of selected publications of the SEU, the article highlights some of the representations of family, work and gender which provide the discursive context in which the SEU operates and to which it, in turn, contributes. The article suggests that perspectives found in the post-1945 welfare state continue to influence approaches to problems of exclusion. Whilst there are areas in which current political thinking shows evidence of sensitivity to the social recomposition that has attended economic restructuring since 1970, it is argued that there remain tendencies within SEU discussions which reinforce a more nostalgic constitution of work, family and gender relations. Consequently, the article concludes that the potential of the social exclusion debate to grasp fundamental issues is yet to be fully realised.  相似文献

The National (Country) Party, traditional beneficiary of a countrymindedness ethos in rural and regional Australia, suffered a significant electoral setback at the 1998 federal election from a new conservative force in Australian politics, the One Nation Party. One Nation has been characterised as the party of the ‘old’ Australia, those least able to cope with the pace of recent social and economic changes, rationalisation and centralisation of services and the exodus of people from rural and regional areas. Such a characterisation is supported by findings from this study of the geography of voting and the social correlates of One Nation's support base in the Farrer electoral division in south‐western New South Wales.  相似文献
