    "Bezweifle, daß Online einmal ein großer Teil des Geschäfts von Bertelsmann sein wird. Es wird ein nettes, spezielles Zusatzgeschäft sein." "Wenn wir im Jahr 2000 dort 1 Mio Teilnehmer haben, dann wäre das sehr viel. Weit über unseren Plänen. Wieviel Umsatz im Jahr wird ein Teilnehmer uns bringen? Nehmen wir nur mal an: 500 Mark. Dann wäre dies 500 Mio Mark. Insgesamt wird Bertelsmann im Jahr 2000 vor. einen Umsazu von 35 Mrd erwirtschaften. 22 Mrd sind es jetzt. 8 bis 10% davon sind Gewinn. Es is ausgeschlossen, daß Online einmal das Mediengeschäft bei Bertelsmann dominieren wird. Im übrigen glauben wir an die Koexistenz und Komplementarität der Medien"

    Abstract
    The structural, functional, and production views on learning objects influence metadata structure and vocabulary. The authors drew on these views and conducted a literature review and in-depth analysis of 14 learning objects and over 500 components in these learning objects to model the knowledge framework for a learning object ontology. The learning object ontology reported in this article consists of 8 top-level classes, 28 classes at the second level, and 34 at the third level. Except class Learning object, all other classes have the three properties of preferred term, related term, and synonym. To validate the ontology, we conducted a query log analysis that focused an discovering what terms users have used at both conceptual and word levels. The findings show that the main classes in the ontology are either conceptually or linguistically similar to the top terms in the query log data. The authors built an "Exercise Editor" as an informal experiment to test its adoption ability in authoring tools. The main contribution of this project is in the framework for the learning object domain and the methodology used to develop and validate an ontology.

    Abstract
    Although classification has been an important aspect of astronomy since stellar spectroscopy in the late nineteenth century, to date no comprehensive classification system has existed for all classes of objects in the universe. Here we present such a system, and lay out its foundational definitions and principles. The system consists of the "Three Kingdoms" of planets, stars and galaxies, eighteen families, and eighty-two classes of objects. Gravitation is the defining organizing principle for the families and classes, and the physical nature of the objects is the defining characteristic of the classes. The system should prove useful for both scientific and pedagogical purposes.

    Abstract
    MARC records and online policy documents of selected libraries were reviewed to study the approaches taken by libraries worldwide to catalogue electronic journals. In general, libraries catalogue those electronic journals that are subscribed by them on priority basis. Most of them annotate the e-journal to the print record, some prefer to catalogue them separately, while the majority of the libraries adopt both approaches. While most of the libraries studied prefer full record, cataloguing e-journals separately with a brief record (at least containing MARC fields 245, 500, and 856) that identifies and locates the resource seems to be the best practice.

    Abstract
    A summary of brain theory is given so far as it is contained within the framework of Localization Theory. Difficulties of this "conventional theory" are traced back to a specific deficiency: there is no way to express relations between active cells (as for instance their representing parts of the same object). A new theory is proposed to cure this deficiency. It introduces a new kind of dynamical control, termed synaptic modulation, according to which synapses switch between a conducting and a non- conducting state. The dynamics of this variable is controlled on a fast time scale by correlations in the temporal fine structure of cellular signals. Furthermore, conventional synaptic plasticity is replaced by a refined version. Synaptic modulation and plasticity form the basis for short-term and long-term memory, respectively. Signal correlations, shaped by the variable network, express structure and relationships within objects. In particular, the figure-ground problem may be solved in this way. Synaptic modulation introduces exibility into cerebral networks which is necessary to solve the invariance problem. Since momentarily useless connections are deactivated, interference between di erent memory traces can be reduced, and memory capacity increased, in comparison with conventional associative memory

    Abstract
    Explicit definition of the limits of citation analysis demands additional tests for the validity of citation analysis. The stability of citation rankings over time can be regarded as confirming the validity of evaluative citation analysis. This stability over time was investigated for two sets of citation records from the Web of Science (Thomson Reuters, Philadelphia, PA) for articles published in journals classified in Journal Citation Reports as Mathematics. These sets are of all such articles for the 1960s and for the 1970s. This study employs only descriptive statistics and draws no inferences to any larger population. The study found a high correlation from one decade to the next of rankings among sets of most highly cited articles. However, the study found a low correlation for rankings among articles whose ranks were the 500 directly below those of the 500 most cited. This perhaps expected result is discussed in terms of the Glänzel-Schubert-Schoepflin stochastic model for citation processes and also in connection with an account of the purposes of evaluative citation analysis. This interpretative context suggests why the limitations of citation analysis may be inherent to citation analysis even when it is done well.

    Abstract
    RLG has used METS for a particular application, that is as a wrapper for structural metadata. When RLG cultural materials was launched, there was no single way to deal with "complex digital objects". METS provides a standard means of encoding metadata regarding the digital objects represented in RCM, and METS has now been fully integrated into the workflow for this service.
