An exploration of affect factors and their role in user technology acceptance: Mediation and causalityAbstract Affect factors have gained researchers' attention in a number of fields. The Information Systems (IS) literature, however, shows some gaps and inconsistencies regarding the role of affect factors in human–computer interaction. Building upon prior research, this study aims at a better understanding of affect factors by clarifying their relationships with eac... ...

Overlap in bibliographic databasesAbstract Bibliographic databases contain surrogates to a particular subset of the complete set of literature; some databases are very narrow in their scope, while others are multidisciplinary. These databases overlap in their coverage of the literature to a greater or lesser extent. The topic of Fuzzy Set Theory is examined to determine the overlap of coverage in th... ...

Duality revisited: Construction of fractional frequency distributions based on two dual Lotka lawsAbstract Fractional frequency distributions of, for example, authors with a certain (fractional) number of papers are very irregular and, therefore, not easy to model or to explain. This article gives a first attempt to this by assuming two simple Lotka laws (with exponent 2): one for the number of authors with n papers (total count here) ... ...

The power of power laws and an interpretation of Lotkaian informetric systems as self‐similar fractalsAbstract Power laws as defined in 1926 by A. Lotka are increasing in importance because they have been found valid in varied social networks including the Internet. In this article some unique properties of power laws are proven. They are shown to characterize functions with the scale‐free property (also called self‐similarity property ) as... ...

Relations between the continuous and the discrete Lotka power functionAbstract The discrete Lotka power function describes the number of sources (e.g., authors) with n = 1, 2, 3, … items (e.g., publications). As in econometrics, informetrics theory requires functions of a continuous variable j , replacing the discrete variable n . Now j...

Intended and unintended consequences of a publish‐or‐perish culture: A worldwide surveyHow does publication pressure in modern‐day universities affect the intrinsic and extrinsic rewards in science? By using a worldwide survey among demographers in developed and developing countries, the authors show that the large majority perceive the publication pressure as high, but more so in Anglo‐Saxon countries and to a lesser extent in Western Europe. However, scholars see both the ... ...
