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. 相似文献
This article addresses the problem of specification uncertainty in modeling spatial economic theories in stochastic form. It is ascertained that the traditional approach to spatial econometric modeling does not adequately deal with the type and extent of specification uncertainty commonly encountered in spatial economic analyses. Two alternative spatial econometric modeling procedures proposed in the literature are reviewed and shown to be suitable for analyzing systematically two sources of specification uncertainty, viz., the level of aggregation and the spatio-temporal dynamic structure in multiregional econometric models. The usefulness of one of these specification procedures is illustrated by the construction of a simple multiregional model for The Netherlands. 相似文献
This paper is a statistical and geological study of the results of analysis of flint from British and West European flint mines, carried out by emission and atomic absorption spectroscopy. Groups of flint specimens were studied from each geographically separate flint mining area. Flints were analysed for a group of easily measured trace elements shown by previous work to be generally present. The ratios between the trace elements form a consistent pattern for each flint mine and statistically valid differences of pattern can be recognized between different flint mines. A geological investigation shows that the measured trace elements may be derived from clay minerals and explains geographical and statistical variation in the composition of flint in terms of its mode of origin in the chalk. An advanced statistical technique allows individual flint specimens of unknown origin to be attributed by their composition to one or other of the identified flint sources. The archaeological implications of this study are discussed. 相似文献
A method is described for the identification of the origin of flint artefacts. The method is based on the variation in the trace element concentrations for different origins. The trace element concentrations were determined by non-destructive neutron activation analysis. The identification was obtained from a pattern recognition analysis. 相似文献
ABSTRACT Increasing strains on self-sufficiency within the block of East European command economies resulted in the dramatic decision to change over to an economic system largely based on market forces. The painfulness of the ensuing transformation process will be mitigated somewhat by supportive economic policies of the West, including the European Community which is itself aiming at complete economic integration by the end of 1992. The consequences for the developing countries of these far-reaching policy changes in East and West are likely to be negative, at least in the immediate future. This is true for the volume of development assistance given by East and West, as well as for the export prospects of developing countries. Favourable effects might at best be expected in the longer run. 相似文献

This paper explores attempts to establish a network of firms and organizations to develop the multimedia industry at a regional level. The paper sets out its review in the context of the regional economy, and then details the nature of the networking process under investigation. An evaluation of networking in this context is provided, based on detailed empirical research. Lessons are drawn from the experiences of seeking economic modernization through organizational networks. 相似文献
