Results of analyses of the photoperiod response gene (PPD-H1) and simple sequence repeats (SSRs) in modern landraces of cultivated barley were used as evidence for the mechanism of agricultural spread in Neolithic Europe. In particular, we explored the usefulness of considering adaptive genes as indicators of past selective pressures acting on crops, during their spread through Europe. In some areas, such as the Alpine region, Britain and Scandinavia, we have evidence to suggest that the adaptation of crops to certain climatic conditions may have contributed to the timing of agricultural spread. At the northern fringes of Europe, and in higher altitude locations in central Europe, the introduction of more suitably adapted cereals may have facilitated successful agriculture to trigger agricultural expansion. This research opens up the possibility of investigating other genetic adaptations to climate, which would permit a fuller evaluation of the relative contributions of climate/crop and forager/farmer interactions in the process of agricultural spread.  相似文献

Abstract: Indigenous activists and anarchist Settler people are articulating common ground in opposition to imperialism and colonialism. However, many anarchists have faced difficulties in Indigenous solidarity work through unintentional (often unwitting) transgressions and appropriations. Through the introduction of settler colonialism as a complicating power dynamic, we observe that anarchists bring unconscious spatial perceptions into their solidarity work. Further, Indigenous activists often perceive anarchists as Settler people first and foremost, which carries another set of spatial implications. We examine a number of examples of anarchist and Indigenous activism, at times empowering and at times conflictual, in order to reveal some general trends. Through an intensive synthesis of Indigenous peoples’ theories and articulations of place‐based relationships, we suggest that deeper understandings of these relationships can be of great importance in approaching solidarity work in place and with respect.  相似文献

Why do policies fail? There are many answers to this question, and many ways of answering it. In this paper, we use the tools of policy framing and systems thinking to investigate two recent Australian examples of public policy failure, each involving a different policy milieu and time-span. We show that, in both these cases, unintended consequences arose because governments lost control of the implementation process while remaining politically accountable for the outcomes. We develop the concept of transmitted risk to show how this occurred. We argue that governments expose themselves to this kind of risk when they make policy decisions involving a combination of excessive incentives and poorly controlled third parties.  相似文献

A reappraisal of the material from Norwegian grave finds is necessary, with the primary object of throwing light on the burial custom itself. The study should be based on a minimum of uniform criteria. This will allow direct comparison between the various parts of the country and the different periods.

Those surveys of Norwegian burial customs published to date are no longer in agreement with existing facts.

If such studies are not undertaken, the stagnation evident in the research into the Norwegian Iron Age will only increase.  相似文献

The origins of early Mesoamerican agricultural techniques are not well established. Our charcoal-derived radiocarbon chronology dates cross-valley check dams, or lama-bordos, buried by up to 11.5 m of sediment in arroyos near Coixtlahuaca, Oaxaca, Mexico. Now it is clear that people in highland Mexico built lama-bordos at least 3400–3500 years ago, several hundred years earlier than previously dated engineering systems in Mesoamerica. Lama-bordo systems evolved as intensively and extensively managed landscapes coeval with climate shifting to more arid conditions. They provide clear examples of human-produced stratigraphy and artificial landscapes (stair-stepped valleys). More importantly, these lama-bordo systems signal a major cultural tipping point toward sedentary agricultural life and solidify our understanding of the Neolithic transition in Mesoamerica.  相似文献

ICOMOS charters guide global heritage conservation practices. Fundamental to most is the notion that a ‘monument is inseparable from the history to which it bears witness and from the setting in which it occurs.’ Yet buildings have been moved for centuries. Neither the fabric nor the size of a building, nor planning regulations, nor even heritage listing, have prevented their relocation. This article briefly examines the history of relocation, reviews attitudes to relocation in ICOMOS charters, and analyses two case studies involving the mass relocation of heritage buildings in the UK and in New Zealand to question the assumption that buildings lose their authenticity if moved.  相似文献
