Among the avowed social policies of the Soviet Union are modernization and industrialization, which may be combined under the label of Sovietization, and the spread of Russian language and culture within the USSR, which may be termed Russianization. But there is also a third process at work in which non-Russians lose their ethnic identity in favor of identification with Russian culture. This process, which may be called "Russification," can be measured by the number of non-Russians who declare Russian to be their first language in the census. The authors use correlation analysis and principal components analysis to identify the factors that promote or hinder the Russification process. 相似文献

Technical advances in digital communications facilitate new applications, which are required also by global changes and are based on an intensive use of knowledge. This paper presents such an application and refers to the improving knowledge-based services of German economic agencies that use intensively the Internet and the Web. The presented work is carried out within a German project supported by the Federal Ministry of Economy and Technology BMWT. A key role within the project is a digital experiment involving the development of required economic, social and technical competences for the agencies' staff by using web-based qualification processes and virtual learning communities. 相似文献

Does technology shape music? Aesthetics of assembly at the beginning of the 20th century. This article deals with the relationship between assembly in production technology and similar processes in musical composition. Can composers like Eric Satie, Igor Strawinsky or George Antheil, who used assembly methods in some of their compositions, be called assemblers? The authors point out that all three composers used assembly methods in different ways and with different purposes. Applying a theoretical approach inspired by media studies they come to the conclusion that the conditions under which musical works using assembly methods are shaped do not originate in technology but in the aesthetic convictions of the composer. Apart from assembly methods there are many other compositional principles the composer relies on. Technology may inspire music but does not determine the musical outcome. 相似文献

Wombling is a method for discovering boundaries in a collection of continuous variables observed at the same geographic localities. We extend this method to categorical data. A categorical wombling statistic Ci, which identifies areas of rapid change, is defined for every pair i = 1,…, n of adjacent localities, and is equal to the average number of category mismatches at i. We use both simulation and theory to consider the order statistics of Ci under null hypotheses of randomness, and of spatial autocorrelation for each variable, but independence between variables. Graph-theoretical statistics derived from Ci investigate whether areas of rapid change resemble boundaries. Computer simulation is used to study the distributions of these under the two null hypotheses. The methods are applied to linguistic data in three European areas. Other potential applications exist in biology, linguistics, anthropology, and other social sciences. 相似文献
