    Is Inequality Among Universities Increasing? Gini Coefficients and the Elusive Rise of Elite Universities.Willem Halffman & Loet Leydesdorff - 2010 - Minerva 48 (1):55-72.
    One of the unintended consequences of the New Public Management (NPM) in universities is often feared to be a division between elite institutions focused on research and large institutions with teaching missions. However, institutional isomorphisms provide counter-incentives. For example, university rankings focus on certain output parameters such as publications, but not on others (e.g., patents). In this study, we apply Gini coefficients to university rankings in order to assess whether universities are becoming more unequal, at the level of both the (...)

    An analytical scheme that differentiates among the various types of cognitive and social functions of citations is used as the basis for an analysis of the results of a questionnaire designed to probe the citing behavior of a group of scientists who had cited one of four papers originating from a single biochemical laboratory. Even when papers fall within a relatively well-defined research area and are based on research conducted within a single lab, groups of scientists to which a given (...)

  6. Scientific Communication and Cognitive Codification: Social Systems Theory and the Sociology of Scientific Knowledge.Loet Leydesdorff - 2007 - European Journal of Social Theory 10 (3):375-388.
    The intellectual organization of the sciences cannot be appreciated sufficiently unless the cognitive dimension is considered as an independent source of variance. Cognitive structures interact and co-construct the organization of scholars and discourses into research programs, specialties, and disciplines. In the sociology of scientific knowledge and the sociology of translation, these heterogeneous sources of variance have been homogenized a priori in the concepts of practices and actor-networks. Practices and actor-networks, however, can be explained in terms of the self-organization of the (...)

    The Knowledge Content of Science and the Sociology of Scientific Knowledge.Loet Leydesdorff - 1992 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 23 (2):241-263.
    Several, seemingly unrelated problems of empirical research in the 'sociology of scientific knowledge' can be analyzed as following from initial assumptions with respect to the status of the knowledge content of science. These problems involve: (1) the relation between the level of the scientific field and the group level; (2) the boundaries and the status of 'contexts', and (3) the emergence of so-called 'asymmetry' in discourse analysis. It is suggested that these problems can be clarified by allowing for cognitive factors (...)

    ‘Meaning’ as a Sociological Concept: A Review of the Modeling, Mapping and Simulation of the Communication of Knowledge and Meaning. [REVIEW]Loet Leydesdorff - 2011 - Social Science Information 50 (3-4):391-413.
    The development of discursive knowledge presumes the communication of meaning as analytically different from the communication of information. Knowledge can then be considered as a meaning which makes a difference. Whereas the communication of information is studied in the information sciences and scientometrics, the communication of meaning has been central to Luhmann’s attempts to make the theory of autopoiesis relevant for sociology. Analytical techniques such as semantic maps and the simulation of anticipatory systems enable us to operationalize the distinctions which (...)

    Luhmann's Sociological Theory: Its Operationalization and Future Perspectives.Loet Leydesdorff - 1996 - Social Science Information 35 (2):283-306.
    Luhmann has proposed a second-order theory of social communications, but its formalization in terms of second-order systems theory has remained underdeveloped. Second-order systems theory is a formal option and, furthermore, Shannon's mathematical theory of communication is available. The operationalization of Luhmann-type communications in terms of Shannon-type communications has theoretical consequences: one is able to distinguish, more clearly than Luhmann did, between not meaningful information and its potential meaning after selection by an observing system. Structural coupling between co-evolving systems can be (...)

    The Possibility of a Mathematical Sociology of Scientific Communication.Loet Leydesdorff - 1996 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 27 (2):243-265.
    The focus on discourse and communication in the recent sociology of scientific knowledge offers new perspectives for an integration of qualitative and quantitative approaches in science studies. The common point of interest is the question of how reflexive communication systems communicate. The elaboration of the mathematical theory of communication into a theory of potentially self-organizing entropical systems enables us to distinguish the various layers of communication, and to specify the dynamic changes in these configurations over time. For example, a paradigmatic (...)

  16. Has the Study of Philosophy at Dutch Universities Changed Under Economic and Political Pressures?Loet Leydesdorff & Barend Van der Meulen - 1991 - Science, Technology and Human Values 16 (3):288-321.
    From 1980 until 1985, the Dutch Faculties of Philosophy went through a period of transition. First, in 1982 the national government introduced a new system of financing research at the universities. This was essentially based on the natural sciences and did not match philosophers' work organization. In 1983 a drastic reduction in the budget for philosophy was proposed within the framework of a policy of introducing savings by distributing tasks among the universities. Recently, a visiting committee reported on the weak (...)

    Quality Control and Validation Boundaries in a Triple Helix of University-Industry-Government: “Mode 2” and the Future of University Research.Yuko Fujigaki & Loet Leydesdorff - 2000 - Social Science Information 39 (4):635-655.
    How is quality control organized in the new “Mode-2” production of scientific knowledge? When institutional boundaries are increasingly blurred in a triple helix of university-industry-government relations, criteria for quality control in the production of scientific knowledge can be expected to change at the interfaces. The categorization in terms of two modes of knowledge production was introduced by Gibbons et al. to describe changes in the networks of scientific communications. These changes were specified mainly as institutional parameters in order to deal (...)

    The Non-Linear Dynamics of Meaning Processing in Social Systems.Loet Leydesdorff - 2009 - Social Science Information 48 (1):5-33.
    Social order cannot be considered as a stable phenomenon because it contains an order of reproduced expectations. When the expectations operate upon one another, they generate a non-linear dynamics that processes meaning. Specific meaning can be stabilized, for example, in social institutions, but all meaning arises from a horizon of possible meanings. Using Luhmann's social systems theory and Rosen's theory of anticipatory systems, I submit equations for modeling the processing of meaning in inter-human communication. First, a self-referential system can use (...)

    Self-Organization of Meaning and the Reflexive Communication of Information.Loet Leydesdorff, Alexander M. Petersen & Inga Ivanova - 2017 - Social Science Information 56 (1):4-27.
    Following a suggestion from Warren Weaver, we extend the Shannon model of communication piecemeal into a complex systems model in which communication is differentiated both vertically and horizontally. This model enables us to bridge the divide between Niklas Luhmann’s theory of the self-organization of meaning in communications and empirical research using information theory. First, we distinguish between communication relations and correlations among patterns of relations. The correlations span a vector space in which relations are positioned and can be provided with (...)

    Is the European Monetary System Converging to Integration?Loet Leydesdorff & Nienke A. Oomes - 1999 - Social Science Information 38 (1):57-86.
    The emerging system at the European level can be conceptualized as a pattern of relations among member states that tends to be reproduced despite disturbances in individual trajectories. The Markov property is used as an indicator of systemness in the distribution. The individual trajectories of nations participating in the European Monetary System are assessed using an information theoretical model that is consistent with the Markov property in the multivariate case. Economic and monetary integration are analysed using independent data sets. Increasing (...)

    Recent Developments in China–U.S. Cooperation in Science.Caroline S. Wagner, Lutz Bornmann & Loet Leydesdorff - 2015 - Minerva 53 (3):199-214.
    China’s remarkable gains in science over the past 25 years have been well documented but it is less well known that China and the United States have become each other’s top collaborating country. Science and technology has been a primary vehicle for growing the bilateral relationship between China and the United States since the opening of relations between the two countries in the late 1970s. During the early 2000s, the scientific relationship between China and the United States—as measured in coauthored (...)
