Vom GIS zur Geodateninfrastruktur

Geographische Informationssysteme sind nicht mehr ausschlie?lich ein Werkzeug für Spezialisten. In immer mehr Bereichen der raumbezogenen Dokumentation, Planung und Analyse werden diese Werkzeuge eingebunden. Der Beitrag beschreibt die Entwicklung und analysiert die technologischen Hintergründe. Viel wichtiger als technologische Ver?nderungen aber sind organisatorische und gesellschaftliche Ver?nderungen, die auf dem Wege zur Informations- und Wissensgesellschaft eine neue Bewertung des Nutzens von Geoinformation bewirken. Geoinformation wird zunehmend als Wirtschaftsgut betrachtet, das am Markt gehandelt werden kann und ein erhebliches Wirtschaftspotential aufweist. Allerdings ist der Markt für Geoinformationen durch Strukturen gepr?gt, die die Nutzung des wirtschaftlichen Potentials deutlich behindern. Geodateninfrastrukturen gelten als ein wichtiges Instrument zur überwindung der Marktbarrieren und zur Etablierung neuartiger Wertsch?pfungsketten und innovativer Jobchancen für Experten für die Veredlung und Verdichtung von raumbezogenen Informationen.     

Vom Denken in Analogien

Analogy as a scientific method has been criticized during the last decades; only for heuristic purposes it has been accepted. On the other side especially proportional analogies have a long tradition in European thought since Plato and Aristotle, for, as Aristotle puts it, analogies allow a connection between different and unbridgeable ontological areas. As examples for such connections the analogia entis of Thomas of Aquino and the Kantian Analogies of Experience are discussed. They give us hints for a new view of analogies, which during the Middle Ages were not only of heuristic value, but were accepted as a proof: Analogies do not only produce hypotheses, moreover, they build up new views of the world, they are the background of paradigms, for they create structures by introducing similarities and proportions.     

Vom Nutzen des Augenblicks für die Projekte der Wissenschaft

Using the Instant for the Projects of Science . Focusing on Bachelard's books L'Intuition de l'instant (1932) and La dialectique de la durée (1936), the paper deals with Bachelard's discontinuous and serial concept of time that is formulated against Henri Bergson's concept of duration. With a view to the philosophical concept of monadology, to the theory of relativity, and to the contemporary psychological and neurological research, the paper points to the significance of the instant for Bachelard's concept of temporality, for his desubjectified concept of the individual as well as his discontinuous concept of matter. Moreoever, the paper explores the discontinuous conception of temporality in Bachelard's epistemological writings. The paper argues that Bachelard's discontinuous concept of the specific temporality of science is based on a fundamental discontinuity of reality of both physical as well as psychological processes.     

Wissenschaft im Gehäuse: Vom Nutzen und Nachteil institutionengeschichtlicher Perspektiven

Research is realized in social and cultural context, it is established in institutions, as far as different forms and conditions of practice are concerned. In this article some German examples demonstrate how flexible and varied the institutions of research can be during the course of history of science. The first part deals with historically grown, yet chronologically overlapping institutions of research: beginning with the lonely scholar, going on to hierarchally organized big science and ending up with virtual institutions. In the second part, at the intersection of political‐social administration and styles of scientific thought terms like German Realpolitik, science in context, and science policy are discussed within the modernization process.
