- Abstract
- Bradford's law of scatter was applied to the analysis of the authors of source documents on the subject of classification schemes, published in core periodicals over the period 1981-1990. Results indicated that: core authors of the international classification system literature are Library of Congress, M. Dewey, S. Ranganathan, J. Comaroni, A. Neelameghan, L. Chan and K. Markey; the highly cited authors are linked either to the developers of the classification schemes or to a research centre, or else they authored the most frequently cited books; and the data conforms to Bradford's Law of Scatter

- Abstract
- The h-index provides us with 9 natural classes which can be written as a matrix of 3 vectors. The 3 vectors are: X = (X1, X2, X3) and indicates publication distribution in the h-core, the h-tail, and the uncited ones, respectively; Y = (Y1, Y2, Y3) denotes the citation distribution of the h-core, the h-tail and the so-called "excess" citations (above the h-threshold), respectively; and Z = (Z1, Z2, Z3) = (Y1-X1, Y2-X2, Y3-X3). The matrix V = (X,Y,Z)T constructs a measure of academic performance, in which the 9 numbers can all be provided with meanings in different dimensions. The "academic trace" tr(V) of this matrix follows naturally, and contributes a unique indicator for total academic achievements by summarizing and weighting the accumulation of publications and citations. This measure can also be used to combine the advantages of the h-index and the integrated impact indicator (I3) into a single number with a meaningful interpretation of the values. We illustrate the use of tr(V) for the cases of 2 journal sets, 2 universities, and ourselves as 2 individual authors.

- Abstract
- A problem, raised by Wallace (JASIS, 37,136-145,1986), on the relation between the journal's median citation age and its number of articles is studied. Leaving open the problem as such, we give a statistical explanation of this relationship, when replacing "median" by "mean" in Wallace's problem. The cloud of points, found by Wallace, is explained in this sense that the points are scattered over the area in first quadrant, limited by a curve of the form y=1 + E/x**2 where E is a constant. This curve is obtained by using the Central Limit Theorem in statistics and, hence, has no intrinsic informetric foundation. The article closes with some reflections on explanations of regularities in informetrics, based on statistical, probabilistic or informetric results, or on a combination thereof

- Abstract
- Using data from the Web of Science (WoS), we analyze the mutual information among university, industry, and government addresses (U-I-G) at the country level for a number of countries. The dynamic evolution of the Triple Helix can thus be compared among developed and developing nations in terms of cross-sectional coauthorship relations. The results show that the Triple Helix interactions among the three subsystems U-I-G become less intensive over time, but unequally for different countries. We suggest that globalization erodes local Triple Helix relations and thus can be expected to have increased differentiation in national systems since the mid-1990s. This effect of globalization is more pronounced in developed countries than in developing ones. In the dynamic analysis, we focus on a more detailed comparison between China and the United States. Specifically, the Chinese Academy of the (Social) Sciences is changing increasingly from a public research institute to an academic one, and this has a measurable effect on China's position in the globalization.

- Abstract
- Unter kognitiver Mobilität verstehe ich im folgenden nicht die Mobilität von Information, sondern die Bewegung des Denkens, und zwar hier des wissenschaftlichen Denkens. Wissenschaftliches Denken vollzieht sich disziplinär sowie interdisziplinär, im informationellen Austausch von Disziplinen und Forschungsgebieten. Dieser Austausch unterliegt, wie die Wissenschaftsgeschichte lehrt, einer Entwicklungsdynamik, die als Abfolge von Wanderungen oder Übergängen zwischen Forschungsgebieten in folgendem Sinn verständen werden kann. Beschäftigt sich ein Forscher A zum Zeitpunkt t1 mit Forschungsgebiet X und zum Zeitpunkt t2 als nächstes mit Forschungsgebiet Y, so liegt ein Übergang von X nach Y vor. Gibt es für diese Art von Übergängen charakteristische Eigenschaften oder Regularitäten.> Ein wichtiges Merkmal solcher Übergänge ist der Grad der Verwandtschaft, der kognitiven Affinität zwischen Ausgangs- und Zielgebiet der Migration. Am Beispiel der rund 150.000 Migrationen zwischen den mathematischen Subdisziplinen, wie sie sich in den Zeitschriftenartikel-Nachweisen der Mathematical Reviews von 1959 bis 1975 widerspiegeln, wurde das Verhältnis von kognitiver Mobilität und Affinität empirisch systematisch untersucht. Es bestätigte sich George K. Zipfs "Principle of Least Effort". Zählreiche Mechanismen und Faustregeln der Wissensorganisation dürften der Wirksamkeit dieses Prinzips zugrundeliegen.
