作为坚守民间写作立场的作家,迟子建更衷情于"小人物",她的目光始终投注在处于社会底层的普通乡民和蓬门荜户的市井百姓身上。她小说中的人物是现实土壤滋养出来的,是作家贴近平民生活、用爱与同情浇灌的艺术形象。这些"小人物"总是和他们的生存环境紧密相依,绝没有超越环境的性情与行为,这使得他们与各自的环境如同骨与肉一样生长在一起,甚至显得不是那么鲜明,却又正是无数面目模糊、"无足轻重"的底层人物的文学再现。  相似文献

Forecasting the thermal efficiency of a set of power plants belonging to a country is important for energy, water, and environmental planning.In this article an analysis of the way in which the system thermal efficiency (STE) changes is provided, and a forecasting model for the electric utilities of technology importing countries is developed.The model is based on the identification of the speed with which technology is transferred from abroad and of the adjustment process of the system's efficiency to that of the best plant's.The application of the calculation to the South African utility shows that the STE in the year 2015 will be 20 to 25 percent higher than that in the year 1983.  相似文献

A new methodology for political risk analysis was developed and applied to Canada and Mexico. The ideas of an interdisciplinary team of corporate and country experts were obtained in mid-1982 via a two-round Delphi inquiry on socioeconomic change and a survey on business contingencies in Canada and Mexico. The information provided by the panelists was used to describe possible future conditions in Canada and Mexico in the context of alternative U.S. and international conditions.  相似文献

The Japanese concept of “industrial policy” is the subject of this presentation. The central role of the Ministry of International Trade and Industry in the formulation of industrial policy for Japan over the past 35 years is reviewed. Several strategic phases are identified: 1945–1952, reconstruction of the economy; 1952–1960, comparative advantage strategy in capital-intensive industries; 1960–1973, transition to an open economy; 1973 to present, positive support policy for promising industries, e.g., subsidies for high-tech sectors and adjustive policy for declining industries (e.g., disposing of excess capacity in the textile sector). The advantages of National industrial policies for the world economy are indicated.  相似文献

In a 1980 study, an attempt was made to provide some degree of quantitative precision to the term “state-of-the-art” by developing an SOA measure for computers and antibiotics. This study expands on the convention developed in the earlier work and applies the approach to five technologies: aircraft turbine engines, high-temperature materials as used in blades and vanes, manmade fibers, farm tractors, and coal gasification. Satisfactory state-of-the-art measures were developed for aircraft turbine engines and high-temperature materials, and the maturity of farm tractor technology was confirmed. The convention also revealed that manmade fiber technology has been in a refining mode since the introduction of nylon. Coal gasification has not gained enough commercial experience to merit a state-of-the-art measure.  相似文献
