Im STANDORT 3/1999 haben Heiner Monheim, Maike Schwarte und Christoph Winkelk?tter im Vorfeld des 52. Deutschen Geographentags in Hamburg die Ergebnisse von 60 Expertengespr?chen zum Perspektivenwechsel in
der deutschen Geographie vorgestellt. In dem vorliegenden Beitrag werden diese Befunde durch weitere Prim?r- und Sekund?ranalysen
erg?nzt, die im Rahmen einer Sonderveranstaltung “Zur Lage der Geographie in Deutschland” beim Geographentag vorgestellt und
diskutiert wurden. Die Grundlage bilden Arbeiten von Studierenden der Universit?t Trier im Rahmen eines Forschungspraktikums
und einer Projektstudie. In dem vorliegenden Beitrag wird ein Auszug der wichtigsten Ergebnisse der Studien und der Podiumsdiskussion
in Hamburg vorgestellt. Das Projekt wurde durch die Deutsche Gesellschaft für Geographie mit 5000 DM gef?rdert. Der DVAG hat
die Projekte durch logistische Hilfe bei den Befragungen und durch Gespr?chsbereitschaft bei den Diskussionen aktiv unterstützt. 相似文献

Abstract. We investigate the ( r ∣ X p )‐medianoid problem for networks. This is a competitive location problem that consists of determining the locations of r facilities belonging to a firm in order to maximize its market share in a space where a competitor is already operating with p facilities. We consider six scenarios resulting from the combination of three customer choice rules (binary, partially binary, and proportional) with two types of services (essential and unessential).
Known discretization results about the existence of a solution for the set of nodes are extended. Some examples and computational experience using heuristic algorithms are presented. 相似文献

This article discusses the current state of the geography discipline in Spanish Universities after putting into action the European Higher Education Area. After decades of geography teaching, following theoretical and expository discourse models, the so-called Bologna Process has been a great opportunity to reflect what geography should be taught, how geography should be taught and why geography should be taught. Aspects such as competences, employability, learning methodologies, assessment, Geographical Information Systems domain have been incorporated into the renewal of geography teaching in Spanish higher education, which has contributed to the strengthening of geography in a context of geospatial technologies revolution and public awareness of spatial challenges. 相似文献

In recent years, unemployment protection systems based on individual savings have been instituted in several developing countries. Chile was one of the first to establish such a system, which at the time was widely cited as a model for other countries. This article discusses the particular political context in which the Chilean system was created before examining how it works in terms of coverage and levels of benefits received by unemployed workers. The authors undertake a detailed analysis of the administrative data produced by the system and conclude that the insurance covers only a small proportion of the unemployed, as most workers generally had precarious jobs that did not allow them to contribute to the system consistently. The Chilean case illustrates how difficult it is to establish functioning unemployment insurance in developing countries with precarious labour markets. Based on the interaction between employment characteristics and the conditions imposed by the benefit system, the article assesses the efficacy of the Unemployment Insurance Savings Accounts (UISA) system and analyses whether it can indeed serve as a model for other developing countries. 相似文献

Abstract Cropsey's book, Plato's World, contains his longest and most sustained reflections on a set of Platonic dialogues, but it is not the first work he published on Plato or the last he intended to write. His last collection of essays, On Humanity's Intensive Introspection, shows that in his writings on Plato Cropsey was attempting to answer a broader question: What is philosophy? 相似文献
