    Infrastruktur und Demographie - Herausforderung für Deutschland

    Get PDF
    Rückgang und Alterung der Bevölkerung werden als eine der größten Herausforderungen der zukünftigen Entwicklung der Bundesrepublik Deutschland dargestellt. Neben den Problemen einer abnehmenden und kontinuierlich alternden Bevölkerung werden auch die positiven Gestaltungschancen, etwa Rückgang des Siedlungsdrucks, der Flächeninanspruchnahme und -versiegelung, angesprochen. Darüber hinaus wird auf die Konsequenzen für den Umbau der Städte und Regionen eingegangen. Für die Erarbeitung zukunftsfähiger Entwicklungskonzepte wird eine stärkere Verzahnung von Raumordnungs-, Verkehrs- und Baupolitik gefordert. Eine zentrale Aufgabe ist die Erhaltung guter und bezahlbarer Infrastrukturangebote unter den Bedingungen einer abnehmenden und alternden Bevölkerung. Hierbei wird dem System der Zentralen Orte als Grundgerüst zur Bewältigung von regionalen Anpassungsprozessen eine wichtige Bedeutung beigemessen.The depletion and ageing of the population are viewed as one of the most serious challenges for the future development of the Federal Republic of Germany. As well as outlining the problems associated with a dwindling and constantly ageing population, the author – more positively – also addresses the opportunities this harbours for planned development, e.g. less pressure to release land for settlement development and thus a reduction in the rate of land being covered by built development. The author also discusses the consequences for the remodelling of towns and regions. As far as the development of sustainable development strategies is concerned, the author calls for greater interlocking and co-ordination between more comprehensive spatial-planning policies and transport and building policies. A central challenge in this context is to protect the provision of good and affordable infrastructure during a period when the population is both dwindling and ageing. The central-place system has an important role to play here as the framework for organising adjustment processes at the regional level

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Get PDF
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
