Iran's scientific impact has suffered hard from decades of imposed and self‐elected isolation from Western influences and international collaboration. Lately, however, the world has witnessed a remarkable increase in scientific publications from Iranian scientists in fields like nanotechnology; material science; and, perhaps most pronounced, chemistry. In this article, the factors behind this “publication boom” are discussed and examined together with an analysis of the coherence between the country's long‐term research strategies and short‐term needs in relation to present organic chemical research conducted at various Iranian universities and institutes. Organic chemistry is a keystone in important Iranian industrial sectors like the petroleum and agricultural industries, and also in the growing field of life science and pharmacology. The development of the petroleum industry and further refinement of raw oil into value‐added fine chemicals holds a key position in the reinforcement of the Iranian economy and labor market, thus motivating a governmental investment in chemical science and research. Taking an approach to find a reasonable balance with the impact from Western and Far Eastern scientific communities, Iran's own scientific roots and Islamic ideology could well be the success factor in becoming a worthy player on the international scientific arena. 相似文献

The origin and dispersal of the first human inhabitants of the Polynesian Triangle have been studied from many perspectives and significant progress in our understanding of Polynesian prehistory has derived from an intermingling of linguistics, archaeology, and genetics. Contributions from the ethnographic record, however, have been limited by the dearth of comparative methods that are useful for reconstructing prehistory and identifying and analyzing cross-cultural trends. For more than fifty years, cladistic phylogenetic methods have been used to reconstruct the evolutionary history of biological systems from contemporary trait distributions. These rigorous methods are applied herein to reconstruct the prehistoric evolution and dispersal of Polynesian bark cloth, using ethnographic data recorded since European contact with Polynesian cultures. Contrary to expectation given the earlier settlement of Western Polynesia, the Eastern Polynesian bark cloth traditions retained many ancestral features. In contrast, a suite of innovations appear in the Western Polynesian bark cloth traditions and it is asserted herein that the distribution of these traits may be associated with the rise of the Tongan maritime Empire. Within Eastern Polynesia, the pattern of diversification of bark cloth traditions is consistent with the breakdown of interaction spheres late in the settlement era. 相似文献

Explaining the emergence of status inequality in human societies is an important priority for many anthropological archaeologists, particularly those whose research includes intermediate scale societies (complex hunter–gatherers and early agriculturalists). Yet, fine grained records of emergent inequality are still exceedingly rare. This paper outlines a fine-grained record of cultural change from the Keatley Creek site, a complex hunter–gatherer village in British Columbia, in which it is possible to recognize the emergence of inequality and its demographic and economic correlates. Results of the study suggest that status inequality emerged abruptly after an extended period of socio-economic stability in the village under conditions of adversely altered resource conditions, demographic packing, and subsistence resource diversification and extensification. 相似文献

There is an ever-greater popular attachment to the commemoration of Anzac Day in Australia, with growing commercial, popular and institutional support around the country. This resurgence has also generated significant disagreement among historians, shaping the historiography of Anzac in recent years and raising important questions about Australia’s current obsession with Anzac: is it a reflection of increasing popular historical engagement, or an ideologically driven ‘mobilisation’ of the past? While various scholars have sought to unpack and understand this potent phenomenon of national sentiment, this article, based on a series of oral interviews with ordinary Australians in selected communities, reveals an uncertainty and complexity in many vernacular responses to Anzac that need to be included if that commemorative sentiment is to be properly understood. 相似文献
