Jinmium rock shelter is famous for the claims made by Fullagar et al. (1996) for the early human colonization and ancient rock art of northern Australia. These claims were based on thermo-luminescence ages obtained for the artefact-bearing quartz sediments that form the floor deposit at the site. In this paper, we outline the background to the optical dating programme at Jinmium, and describe the experimental design and statistical methods used to obtain optical ages from single grains of quartz sand. The results, interpretations, and implications of this dating programme are reported in a companion paper (Roberts et al. 7999, this volume).  相似文献

Everywhere the 1990s have been characterized by an odd mixture of ideological triumphalism—Fukuyama's “end of history” being only the crassest example—and of ideological uncertainty—can there be, should there be, a “third way”? For all its pretensions to universality, the “New World Order” has never lost a fragility in appearance. Students of historiography can scarcely be surprised to learn that an uneasiness over the present and future has in turn frequently entailed uncertainty about the past and particularly about those parts of the past which had seemed most able to give clear and significant “lessons.” One evident example is the history of what in my Explaining Auschwitz and Hiroshima (1993) I called the “long” Second World War, that is, that crisis in confidence in the relationship between political and economic liberalism and the nation-state which, by the end of 1938, had left only Britain, France, the Low Countries, and Scandinavia as in any sense preserving those “liberal” freedoms which had spread across Europe since 1789. In this article, I briefly review the most recent difficulties World War II combatant societies have had in locating a usable past in the history of those times. However, my major focus is on the specific case of Italy, very much a border state in the Cold War system, and today the political home of an “Olive Tree” and a “Liberty Pole” whose historical antecedents and whose philosophical base for the future are less than limpid. 1990s Italian historians thus give very mixed messages about the Fascist past; these are the messages I describe and decode.  相似文献

The lack of interest in history in ancient India has often been noted and contrasted with the situation in China and the West. Notwithstanding the vast body of Indian literature in other fields, there is a remarkable dearth of historical writing in the period before the Muslim conquest and an associated indifference to historiography. Various explanations have been offered for this curious phenomenon, some of which appeal to the supposed currency of certain Indian philosophical theories. This essay critically examines such "philosophical explanations."
I argue that it is not true that there was no history in ancient India, and it is not surprising that there was no developed historiography or scientific history. It is both true and surprising that there was no real importance attached to history in ancient India. An adequate philosophical exxplanation for this historica phenomenon, however, is not to be found in appeals to the influence of indigenous metaphysical theories about time and the self. A much more plausible philosophical explanation appeals instead to certain features of classical Indian epistemology.  相似文献

In this article it is argued that conventional agro-ecological and organizational concepts used in pastoral development are strongly biased towards the formulation and enforcement of norms. This leads development experts to attempts to control pastoralists and their herds. The policies and development interventions based on these assumptions have been largely unsuccessful. As a consequence attention for dryland areas and pastoral development has declined among researchers and development agencies. An important reason for this failure is the fundamental misfit between these normative concepts and the reality of dryland ecosystems and pastoral society. In order to show this, an alternative view on rangeland ecology and pastoral society is presented, supported by a case study of Fulbe pastoral society in dryland Central Mali. The authors argue that approaches to pastoral development must be revised in the direction of the dynamics inherent in the pastoral way of life.  相似文献
