Archaeological deposits are often complex and illustrative of an intricate interplay between geogenic and anthropogenic inputs and formation processes. Even for those archaeologists—particularly prehistorians—who consider the basic principles of natural stratigraphy to excavate their sites, they nonetheless typically underutilize the observations and data available at the microstratigraphic level. The technique of soil micromorphology—or archaeological micromorphology as referred to throughout this paper—has seen an astounding increase in its use to answer archaeological questions and archaeological sediments in the last decades. However, we consider that this tool is still quite underutilized and not as mainstream as other techniques. In this paper, we briefly reflect on what can be some of the causes underlying this situation and how we (that is, both producers and consumers of micromorphology data) can go about to change it. The main idea is that we need to establish a better and more approachable way to present micromorphological results and be better at integrating them with the macroscopic archaeological data and research questions.  相似文献

This reports on a project that combined evidence gleaned from aerial photographs, place‐names, interviews, topography, LIDAR data, and sonar bathymetry to locate stone tidal fish weirs in the Molène Archipelago. The results were verified by diver and pedestrian visual surveys. Models of Holocene sea‐level change allowed a group of possibly Late Mesolithic–Early Neolithic weirs to be recognized, with a second group broadly dated to the later Neolithic–Early Bronze Age. The construction of these long megalithic structures is compared to the funerary monuments for which the Molène Archipelago is well known, in terms of technique, cost, and societal organization.  相似文献

This article examines the relationship between time, governance and political participation through a critical engagement with the ‘acceleration thesis’. Whilst the acceleration thesis argues that the ‘shrinking of the present’ is a condition of contemporary governance, others have viewed it as dysfunctional to the democratic process and effective policymaking. By drawing on a wide range of literature and through the use of illustrative examples, this article argues that slow and fast politics have strengths and weaknesses when it comes to the practice of governance and democratic participation. In turn, questions are raised about how public organisations and others might manage temporality and change in an ‘accelerated polity’. The article concludes by calling for further research into the ‘politics of time’ and its effects on public policymaking and political participation.  相似文献

This paper attempts to demonstrate the applicability of certain themes from post‐structuralist theory to issues raised by the Mabo judgment and the subsequent debate over native title. It outlines some common features of a post‐structuralist conception of society, commenting particularly on conceptions of freedom and the shared concern with difference. It then shows how questions of difference and identity raised by Mabo may be described in post‐structuralist terms, and contrasts the treatment of difference by Derrida and Deleuze from a political point of view. Finally, the paper suggests ways in which Mabo may be seen as a significant event, and an exercise of freedom, in Deleuzian terms.  相似文献

There has been considerable recent discussion and debate about change and the need for change in the United States Forest Service. A number of observers have argued that the agency has shifted its emphasis from commodity to non-commodity values of the National Forests, has become more sensitive to environmental and ecological concerns, and has become more responsive to public input. However, to date most articles on the topic of change in the Forest Service have been either theoretical and speculative in nature or have based their conclusions on attitude surveys of agency employees. So far no studies have provided “hard,” empirical evidence of change or have conducted any systematic examination of the presumed causes. This symposium attempts to fill this gap. What follows is the presentation of the analyses of a wide range of important quantitative indicators of agency change. From these analyses, we attempt to answer the following questions: Has the Forest Service indeed been changing? If so, what direction has it taken and how significant has this change been? What are the possible causes of change, and what have been the consequences for National Forest policy? What factors are likely to influence future change in the agency?  相似文献
