This paper presents a selection of results of a comprehensive quantitative, research literature-based study of Dutch energy research. The primary goal of this paper is to provide an overview of what bibliometric data from ISI and non-ISI databases may offer to describe the state of affairs in a scientific field. It illustrates the added value of combining bibliometric indicators of publication output, international visibility, international co-operation, and interdisciplinarity in a study of nuclear energy research in the 1980's when its budget decreased dramatically. 相似文献

This study demonstrates the applicability of a quantitative modeling approach, specifically goal programming, in operationalizing the relationship between environmental variables and specific organizational structural variables for optimal goal attainment. A goal programming model is developed to analyze and determine the optimal relationships for goal attainment. 相似文献

A detailed examination is made of the 1973 US and Soviet serials holdings of the British Library Lending Division (BLLD), the most comprehensive collection of active scientific and technological serials in the world. In total, 6075 US and 2399 Soviet serials were identified. These serials were then assigned on the basis of their titles to over 200 scientific and technological specialty areas. These assignments clearly show that the US is substantially more active than the USSR in the life sciences and social sciences, while the USSR is relatively more active in the physical and engineering sciences. When comparing the absolute size of the US and Soviet serial counts, it is seen that the US outpublishes the USSR in all major fields (i.e., clinical medicine, biomedical research, biology, chemistry, physics, earth/space science, engineering/technology, mathematics/statistics, psychology, and the social sciences).Research performed while on the staff of the Washington office of Computer Horizons, Inc.

This article reports findings from a study of patterns of foreign authorship of articles, and international composition of
journal editorial boards in five leading journals in the field of information science, and scientometrics. The study covers
an American journal and four European journals. Bibliographic data about foreign authors and their national affiliation from
five selected years of publication were analyzed for all journals. The foreign input of articles were extremely high in Information Processing & Management, and Scientometrics, and were relatively low in the other three journals. The number of foreign countries contributing in all journals have increased
rapidly since 1996. Canada, England, Belgium, Netherlands, China, and Spain were the countries with high contributions in
JASIST. The authors from the USA have dominated the foreign-authored articles in all European journals. A simple linear regression
analysis showed that 60% of variation in the proportion of foreign-authored articles in the set of five journals over the
selected years could be explained by the percentage of foreign members on the editorial boards of the journals.
