La relation entre i'état et le développement social peut entre analysée à partir de trois niveaux interconnectés:
- 1 Au niveau de la théorie et de la méthodologie. C'est ce que font Lojkine et Pahl.
- 2 A un niveau général, mais concernant des types théoriquement differenciés d'organisations sociales (c'est à dire, sociétés capitalistes avancées, sociététés socialistes. etc.). C'est le niveau qui concerne cet auteur le plus.
- 3 Au niveau d'une société donnée, durant une période historique déterminéee. C'est à ce niveau que les autres travaux de Lojkine ont été faits.

This paper presents preference axiomatizations of expected utility for nonsimple lotteries while avoiding continuity constraints. We use results by Fishburn (1975), Wakker (1993), and Kopylov (2010) to generalize results by Delbaen et al. (2011). We explain the logical relations between these contributions for risk versus uncertainty, and for finite versus countable additivity, indicating what are the most general axiomatizations of expected utility existing today. 相似文献

Junius and Oosterhaven (2003) developed the GRAS algorithm that minimizes the information gain when updating input–output tables with both positive and negative signs. Jackson and Murray (2004), however, claim that minimizing squared differences in coefficients produces a smaller information gain, which is theoretically impossible. In this comment, calculation errors are sorted out from differences in measures, and it is shown that the information gain needs to be taken in absolute terms when increasing and decreasing cell values occur together. The numerical results show that GRAS outperforms both sign-preserving alternatives in all but one comparison of lesser economic importance. Moreover, as opposed to the result of Jackson and Murray, they show that minimizing absolute differences consistently outperforms minimizing squared differences, which overweighs large errors in small coefficients. 相似文献

Making quantified statements about the uncertainty associated with the lifelength of an item is one of the most fundamental tasks of reliability assessment. Most practitioners routinely do this using one of the several available statistical techniques. The purpose of this paper is two-fold. The first is to give the user an overview of the key tenets of two of the most commonly used parametric approaches. The second is to point out that these commonly used approaches involve strategies that are either ad hoc, or are in violation of some of the underlying tenets. A method that is devoid of logical flaws can be proposed, but this method is difficult to implement. The user must therefore resign to using that technique against which the fewest objections can be hurled. 相似文献

The purpose of this paper is to explore the current intellectual foundation of four leading academic journals within the field of logistics and supply chain management. We were interested to identify the most frequently quoted publications as well as their impact on logistics research. We examined 17,000 references of 412 papers and further analysed the 39 top-references with the means of multidimensional scaling (MDS), cluster- and factor analysis. We were able to identify a mix of textbooks and articles from academic journals and revealed a journal-specific citation pattern, not only in the choice of textbooks but also in the choice of referenced methodology papers. We were also able to identify citation streams and citation areas, where it was surprising to find so many general socio-scientific papers and general papers explaining the character of the field. 相似文献
