The long-term aim of the project is to excavate the entire central area of the Dilmun settlement. During the 1994 and 1995 seasons a further twelve buildings were excavated, most of them located along the main arteries of the settlement. A resistivity survey, followed by selective excavation, determined the size and extent of the site. A well excavated on the eastern flank provided valuable information about the level of Bahrain's aquifers in the Early Dilmun period.  相似文献

Mining of mineral sands has taken place on North Stradbroke Island for over 40 years. Revegetation of mined areas creates a mosaic of seral classes. For a mine site in the northwest of the island, Landsat Thematic Mapper data were used successfully to map the distribution of seven seral classes resulting from mining rehabilitation. Faecal pellet counts were used to assess usage of these areas and surrounding natural forest by swamp wallabies, Wallabia bicolor. Results indicated that revegetated sites from 2 to 4 years in age were heavily used by wallabies. Older revegetated sites, dominated by senile Acacia cunninghamii, and offering little or no forage, were avoided. Swamp wallabies used revegetated sites for night-time feeding sessions and rested, during the day, in surrounding eucalypt forest.  相似文献

After sharing some reflections, I raise three questions. The first asks about the role of nature and reason according to Kant's teleological history, and the extent to which Kant's essays written before the Critique of the Power of Judgment (1790) are “dogmatic,” as his phrase “aim of nature” might suggest. The second asks about Kant's “impure” ethics and the role of religion. What would Kantian religion look like today? The last question concerns the relation between images and ideas—a thornier issue than Kant's initial definitions of imagination and reason would seem to suggest.  相似文献

To efficiently survive, living creatures require some means of recording their experiences, predicting future experiences on the firm basis of such recordings and deciding on actions that help survival and reproduction. For us humans, this is provided by our very large brains. Our brains are adaptable; indeed, we never use the same brain twice. There are two main mechanisms: reversible synaptic plasticity and the irreversible myelination of axons. Culture can be seen as the store of world knowledge, tacit and explicit, that individuals must acquire to facilitate decision-making by defining their range of options and to become acceptable social persons. Such knowledge is encoded, in ways not yet fully understood, in the pattern of our brain’s connections. In rites of passage, one’s social identity is transformed, entailing a significant modification of this pattern. Liminal status, brought about by entrainment with the ritual’s powerfully affective actions, appears to remove the cultural feedbacks that maintained one’s former social identity and enables durable modification to brain connections by means of a greater myelination of existing pathways and myelination of previously unused pathways. Such changes might be empirically observable using non-invasive MRI (magnetic resonance imaging) techniques. The shared intense experience during the liminal period encourages a sense of likeness among participants, which is embedded in their brains by shared patterns of durable connections.  相似文献

Carbon and nitrogen isotope analyses were performed on human and animal bones recovered from pits within Danebury Iron Age hillfort. All results are within the range expected for European Holocene specimens and are similar to those from other Iron Age sites in central southern Britain. Our results indicate that the human diet included a significant amount of animal protein (meat and/or dairy products) consumed on a regular basis, but do not preclude a diet based heavily on cereal consumption. In comparison with the extensive heterogeneity visible in the animal isotope values, the homogeneity of the human values is rather striking. This may be a reflection of the much slower turnover rate of adult human collagen and may also indicate that the humans consumed a much greater variety of food than the fauna (thus averaging many isotopic sources). This is consistent with the role of hillforts as central places and locations for food distribution and exchange.  相似文献

Jack L. Goldsmith and Eric A. Posner are influential academics in American debates on international law. Their recent book, The limits of international law, is appraised in this review article. It discusses the exclusion in their analysis of the possibility that states have a real or perceived interest in complying with international law per se. It explains that this is at odds with the authors' subjective approach to state interests, and essentially guarantees their conclusion that international law compliance is solely instrumental. Furthermore, the article discusses the problem that the authors fail to engage with relevant scholarship that provides a counterpoint to theirs, in particular with regard to constructivism. On the basis of these critiques the review concludes that the book is flawed and cannot be considered to have made its case.  相似文献
