以1999-2003年生物技术学科期刊文献分布曲线为依据,利用知识密度梯度graduR(n)的概念,对知识场中文献分布特征进行分析。结果表明,在任何一个学科的知识场中,集中区文献分布呈间断性变化,离散区文献分布呈连续性变化,从而构成期刊文献分布的基本特征。基于此,指出期刊文献分布特征研究是对文献分布规律的进一步描述。 相似文献

In the Federal Republic of Germany — as in many other industrialized countries higher education has, under the influence of social, economic and political forces, developed from a relatively small, selective and elite-oriented to a large system of mass education. The increasing number of students and university teachers, and the expansion of scientific and technological methods and knowledge has brought about claims for genuine organizational transformations and for massive financial resources. This development has created a number of severe problems in the relationship of the respective socio-economic and political sub-systems; in particular, the relationship between higher education and the labour market has to be considered as a vital but unresolved problem.This article gives a short account of the quantitative development of the German universities and the labour market in the last two decades. It also describes the organizational transformations which followed the federal framework law on higher education (Hochschulrahmengesetz) of January 1976, and deals with some aspects of research in relation to such problems. 相似文献
