Thermal insulation boards and wooden boards were added to the interior side of external walls of vernacular dwellings to form two layers of air cavities, so as to gain excellent thermal performance. The indoor temperature of such dwellings after reconstruction was apparently improved compared with the data before reconstruction both in winter and summer, which verified the feasibility and the effectiveness of the reconstruction technologies proposed.展开更多

They may be, at times, trivial or foolish but they always address the uncertainties of collective and individual identities in a region boiling with struggles over meanings and knowledge. Because of the liberalization of the Arab television industries, they have successfully integrated the global market and are now elaborating new conventions inspired by both oriental and western references. In this paper, it will explore the depiction of Arab youth as a social construct meant to challenge the nationalistic representation of this ambiguous social category while, at the same time, promoting the regional debate over modernity, Arabism, and change.展开更多

Both historically determined ethno-cultural and socio-political mosaicity of Russia and nature of the Russian state defined priorities of its national policy, aimed at preserving unity and integrity of the country. An ideological basis for forming the imperial universe was the idea of "Russification". The fulfillment of the "Russification" policy in the North Caucasus was to a large extent bound up with an administrative practice, aimed at rearrangement of the local social structures and standardization of the variety of local organizational forms of management. One of the elements of "Russification" was also colonization, so far as the Russian settlers not only changed the regional socio-demographic background, but brought with them a certain "imperial complex". Patterns of positive motivation for "Russification" among local population are found in the field of education, which gave for the mountaineers an opportunity to successful integration into another civilization. However, the processes of imperial unification were fraught with a high conflict potential. The meeting of indigenous social structures with the Russian statehood was inevitably accompanied with the break-up of the whole system of established traditional relations and social roles.展开更多

The ancient Huaxia nation went through two phases in the course of its formation: the self-existent nation and the self-aware nation. The reason the self-existent Huaxia nation1 arose in the Xia and Shang period lies in its unified yet diverse composite state structure that could encompass a variety of buzu within the framework of a dynastic state. The pre-Xia Five Emperors period saw the genesis of the Huaxia nation. During this period, different buzu states were cemented into a diverse yet unified nation-state through a confederation of chiefdoms.展开更多

The article outlines the historical development of the Intemet, from Web 1.0 to a participatory Web 2.0 embedded within everyday life and ultimately to the prospect of an autonomous Internet of Things. The benefits of an ethnographic approach for understanding such developments in depth and examining taken-for-granted assumptions are outlined alongside an account of some of the challenges that digital technologies pose for an ethnographic methodology. Amongst these challenges are the difficulties inherent in mapping out a field site that effectively captures the complexity of online/offline connections and of developing a sufficient degree of immersion and co-presence for a rich understanding to be attained. Finally, the challenges offered by the emergence of mobile Internet, algorithmic filtering of information and unpredictable flows of data are explored. It is suggested that the ethnographer of the Internet can usefully position their task as being to explore a socially constructed yet technologically mediated landscape, immersing themselves in it, interrogating how others experience it and mapping the ways in which it becomes meaningful to those who navigate its complexities.展开更多
