Two important trends will strongly influence growth in emerging economies: one is the increasing role of services as drivers displacing manufacturing that has hitherto been the principal engine of growth in advanced and developing economies alike; the second is the parallel rise of trade in services both directly and embodied in products. The paper shows how the competitiveness and profitability of firms is becoming closely linked to the quality and innovativeness of services, and how the bundling of services with manufactures is the key to earning high returns over the longer term. Between 25 and 40 percent of value added in manufacturing is now in the form of services with high-end manufacturing becoming increasingly services-intensive. The future therefore, seems to lie in the cultivation of product-services systems that harness the full potential of manufacturing and associated pre- and post-production services such as design, R&D, marketing, and post-sale maintenance, especially of sophisticated equipment. The policy implications for emerging economies such as Russia, India, and China are manifold; e.g. for workforce skill development; for innovation systems (the nature of innovation and the orientation of R&D); for the contribution of capital to growth in a services-centered economy; for the maximizing of productivity gains from tradable and non-tradable services, which have been productivity laggards in the past; and for the creation of a facilitating institutional environment.  相似文献

Tree-rings are an important tool for the investigation of paleoclimatic records for regions or periods of time with no instrumental climatic data. However, the responses of different species and sites to various climatic parameters are unusual. In the present study, we developed tree-ring-width chronologies of Cedrus deodara from three different sites of Chitral Hindukush range of Pakistan. The study was conducted to understand tree-growth climate relationship and its applicability in proxy climate investigations. The chronologies covered the past 469 to 595 years, with a mean segment length (MSL) ranging from 148 to 223 years. Climatic data obtained from the three weather stations showed strong correlation and was found useful for tree-ring climate relationships. Correlation Function (CF) and Response Function (RF) analysis showed that spring precipitation (March–May) is a critical limiting factor for tree-ring growth, and temperature prior to November may also play a major role in affecting tree ring-growth. The results exposed that the three sites have continuous relationship indicated that only single species from different locations are affected by the same environmental variables and hence can be used in climate reconstruction in combination. The Cedrus deodara chronologies developed at different locations had several corresponding narrow and wide marker rings indicating a large macroclimatic response to regional climatic conditions. The current study suggests that the tree-rings of Cedrus deodara from the Chitral Hindukush range could be used to develop chronologies for the reconstruction of seasonal climatic variables.  相似文献

Kosovo has been under various forms of international administration since 1999. Although the political dimension of this international experience has been widely studied by scholars — especially those associated with the critical theory of liberal peacebuilding — the economic dimension of international rule has received less attention. This article explores the economic dimension by linking insights from rentier theory with critical approaches to liberal peacebuilding and statebuilding. The postulate informing this article is that the sources of a state's income have an impact on its institutional development. The article discusses liberal peacebuilding through the lens of rentier theory, it analyses the economic management in the early years of the international administration of Kosovo, and describes and explores some of the unintended consequences of this massive international presence in Kosovo for the local economy.  相似文献

Aerial photography has made the single most important contribution to our improved appreciation of the density, diversity and distribution of archaeological sites in Britain since World War Two. This is particularly the case for areas of intensive lowland agriculture where ploughed-out sites are known mainly from marks in the crops growing above them. However, reconnaissance for such cropmarks is not equally effective throughout the lowlands, because of the particular conditions of drier weather, well-drained soils and arable agriculture required before they become visible, and is highly unpredictable.  相似文献

Conservation in urban areas is an active issue, but in remoter areas historical remains are neglected by both public and government. Conservation of maritime archaeological sites is fast becoming important elsewhere. Acknowledging the importance of conservation for other types of historical sites, this paper addresses the need for conservation of the as-yet-unknown number of maritime archaeological sites in Malaysia. This will take time and continuing effort. Malacca Maritime Museum is a case-study, built specifically for showcasing artefacts from shipwrecks. The first such museum in Malaysia, it has benefited tourism as well as preserving objects and educating the public.
