- Abstract
- Die Titel wissenschaftlicher Veröffentlichungen sind von besonderer Bedeutung. Wir haben fast 20 Millionen wissenschaftliche Artikel untersucht und den Anteil von Artikeln mit einem Fragezeichen am Ende des Titels im Laufe der letzten 40 Jahre analysiert. Unsere Studie beschränkte sich auf die Disziplinen Physik, Lebenswissenschaften und Medizin. Dabei haben wir eine deutliche Zunahme der Fragezeichen-Artikel von 50 Prozent auf mehr als 200 Prozent feststellten können. Vor diesem Hintergrund werden im vorliegenden Beitrag die grundsätzlichen Funktionen und Strukturen der Titel wissenschaftlicher Publikationen untersucht. Wir gehen davon aus, dass Marketing-Aspekte die entscheidenden Beweggründe sind für die zunehmende Nutzung von Fragezeichen-Titeln bei wissenschaftlichen Publikationen.

- Abstract
- In single-authored bibliographies only single scientist distribution can be found. But in multi-authored bibliographies single scientists distribution, pairs distribution, triples distribution, etc., can be presented. Whereas regarding Lotka's law single scientists P distribution (both in single-authored and in multi-authored bibliographies) is of interest, in the future pairs P, Q distribution, triples P, Q, R distribution, etc. should be considered Starting with pair distribution, the following question arises in the present paper: Is there also any regularity or well-ordered structure for the distribution of coauthor pairs in journals in analogy to Lotka's law for the distribution of single authors? Usually, in information science "laws " or "regularities " (for example Lotka's law) are mathematical descriptions of observed data inform of functions; however explanations of these phenomena are mostly missing. By contrast, in this paper the derivation of a formula for describing the distribution of the number of co-author pairs will be presented based on wellknown regularities in socio psychology or sociology in conjunction with the Gestalt theory as explanation for well-ordered collaboration structures and production of scientific literature, as well as derivations from Lotka's law. The assumed regularities for the distribution of co-author pairs in journals could be shown in the co-authorship data (1980-1998) of the journals Science, Nature, Proc Nat Acad Sci USA and Phys Rev B Condensed Matter.

- Abstract
- Szava-Kovats demonstrates that the common attribution of the origin of the concept of half-life in subject-oriented journal literatures to the 1960 Burton and Kebler article in American Documentation is not correct. The first use appears to be in C. R. Gosnell's 1944 paper in College and Research Libraries. It was later discussed by J. D. Bernal at the 1958 International Conference on Scientific Information in Washington, DC. While Burton and Kebler do solve some of the theoretical problems by redefining half-life, they do not express confidence in the use of half-life in this milieu, and Burton later advocates in 1961 the term ``median age'' which was introduced by Broadus in this context in 1953.

- Abstract
- The well-documented limitations of journal impact factor rankings and perceptual ratings, the evolving scholarly communication system, the open-access movement, and increasing globalization are some reasons that prompted an examination of journal value rather than just impact. Using a single, specialized journal established in 1960, about education for the Information professions, the author discusses the fall from citation grace of the Journal of Education for Library and Information Science (JELIS) in terms of impact factor and declining subscriptions. Journal evaluation studies in Library and Information Science based on subjective ratings are used to show the high rank of JELIS during the same period (1984-2004) and explain why impact factors and perceptual ratings either singly or jointly are inadequate measures for understanding the value of specialized, scholarly journals such as JELIS. This case study was also a search for bibliometric measures of journal value. Three measures, namely journal attraction power, author associativity, and journal consumption power, were selected; two of them were redefined as journal measures of affinity (the proportion of foreign authors), associativity (the amount of collaboration), and calculated as objective indicators of journal value. The affinity and associativity for JELIS calculated for 1984, 1994, 2004, and consumption calculated for 1985 and 1994 show a holding pattern; however, they also reveal interesting dimensions for future study. Journal value is multidimensional and citations do not capture all the facets; costs, benefits, and measures for informative and scientific value must be distinguished and developed in a fuller model of journal value.
