This article looks at three historical efforts to coordinate the scientific study of biological and cultural aspects of human consciousness into a single comprehensive theory of human development that includes the evolution of the human body, cultural evolution and personal development: specifically, the research programs of Wilhelm Wundt, Lev Vygotsky and Albert Bandura. The lack of historical relations between these similar efforts is striking, and suggests that the effort to promote cultural and personal sources of consciousness arises as a natural foil to an overemphasis on the biological basis of consciousness, sometimes associated with biological determinism.  相似文献

Following President Bush's declaration of a ‘War on Terror’ in 2001, governments around the world introduced a range of counter‐terrorist legislation, policies and practices. These measures have affected not only human rights and civil liberties but also civil society and aid frameworks. Although the Obama administration has renounced the language of the ‘War on Terror’ and taken steps to revoke aspects such as water‐boarding and the detention facility at Guantanamo Bay, the bulk of the legislation and practices associated with the post‐9/11 global security framework remain. The cluster of papers which follow provide detailed studies of the effects of the War on Terror regime on civil society in four contexts: the USA, Spain, Kenya and Uzbekistan. In this way it lays a basis for civil society actors and aid agencies to reflect more strategically on how they should engage with security debates and initiatives in a way that best protects the spaces of civil society and the interests of minority and vulnerable groups. This introduction sets out the three key themes pursued throughout the cluster articles, namely, the selective impact of counter‐terrorist measures on civil society; the particularity of civil society responsiveness to these measures; and the role of aid and diplomacy in pursuing security objectives and its consequences for civil society.  相似文献

A paucity of archaeological remains of Atlantic salmon in Northeast North America has been cited as evidence that the species may have been present in the region only during and after the Little Ice Age (ca. 1450–1850 AD), one of coldest periods of the Holocene. However, significant problems of preservation, recovery and identification remain. Here, improved methods of identification use vertebra structure to distinguish salmon from trout, and strontium/calcium ratios to differentiate sea-run from landlocked salmon. In addition to the Little Ice Age, Atlantic salmon is identified in tightly dated contexts at 7000–6500 and 3500–3000 calendar years BP, during climate periods that were comparatively warm and wet.  相似文献

Situated along the southern fringe of the North Sea basin, northwest Belgium holds great potential for understanding hunter–gatherer responses to environmental change at the Pleistocene–Holocene transition. Recent intensive fieldwork has yielded valuable data on the palaeoenvironment, chronology, and hunter–gatherer mobility and land use in this region. At the Late Glacial/Early Holocene transition this region was comprised of a landscape of coversand ridges and lakes that flanked the northern part of the Scheldt river basin. This landscape was highly productive for hunter–gatherer populations. As the landscape developed in response to the increasing water table caused by the inundation of the North Sea populations responded by changing their forms of mobility and land use. These changes are indicated by the reduction in the number and density of sites, as well as their geographical settings, from the Late Glacial (Federmesser) and Early Mesolithic to the Middle-Final Mesolithic. Late Glacial/Early Mesolithic sites indicate much higher mobility comprised of rapid displacements of camps and re-occupation of the same coversand ridges over long time-spans. Middle/Late Mesolithic sites indicate a reduction in mobility, increasing focus on prolonged riverside settlement, and a more rigid organization of residential sites.  相似文献
