An operative extension of the likelihood ratio test from fuzzy data

In the present paper we are going to extend the likelihood ratio test to the case in which the available experimental information involves fuzzy imprecision (more precisely, the observable events associated with the random experiment concerning the test may be characterized as fuzzy subsets of the sample space, as intended by Zadeh, 1965). In addition, we will approximate the immediate intractable extension, which is based on Zadeh’s probabilistic definition, by using the minimum inaccuracy principle of estimation from fuzzy data, that has been introduced in previous papers as an operative extension of the maximum likelihood method.

Fitting competing risks data to bivariate Pareto models

This paper revisits two bivariate Pareto models for fitting competing risks data. The first model is the Frank copula model, and the second one is a bivariate Pareto model introduced by Sankaran and Nair (1993 Sankaran, P. G., and N. U. Nair. 1993. A bivariate Pareto model and its applications to reliability. Naval Research Logistics 40 (7):1013–1020. doi:10.1002/1520-6750(199312)40:7%3c1013::AID-NAV3220400711%3e3.0.CO;2-7.[Crossref], [Web of Science ®] , [Google Scholar]). We discuss the identifiability issues of these models and develop the maximum likelihood estimation procedures including their computational algorithms and model-diagnostic procedures. Simulations are conducted to examine the performance of the maximum likelihood estimation. Real data are analyzed for illustration.     

宋代与南洋地区航海贸易兴盛新探

宋代中国与南洋地区航海贸易出现了蓬勃发展的态势,探究其原因,除当时存在的特定历史条件外,主要还得益于两宋政府制定了有利于往来的航海贸易政策及和平稳定的外交方针,它保障了贸易双方的平等互利。同时,中国南方港口与南洋地区海上航线的开辟和成熟,也是航海贸易繁荣不可或缺的条件。

L’accountability à l’épreuve des incertitudes : le mandat des acheteurs d’énergie

Based on a survey of energy buyers in big industries, this article inquires into the different ways of explaining the actions they perform in situations of high, uncontrolled uncertainty. Describing energy buyers’ activities, the uncertainties and contradictions affecting them, shows how hard it is to explain them, make them visible or justify the decisions made. Energy buyers develop two forms of “accountability”: they claim to have been granted decision-making powers and ask to be evaluated on the basis of their results; or else they “socialize” their activities by involving corporate managers in decision-making. It is argued that “accountability” is stabilized in line with a collective learning process where the experience of uncertainty has a key place.     

Le marché comme rencontre d’activités de régulation : initiatives et innovations dans l’approvisionnement bio et local de la restauration collective

How to apply Jean-Daniel Reynaud's theory of social regulation to market relations? When applied to the results drawn from fieldwork on the supplying of organic and local produce to catering businesses serving public institutions in France, this grid of analysis shows that organizing this supply chain involves many activities of regulation. An explanation is provided about how hard existing regulations make it to search for local produce. Two contrasting cases show the degree to which the parties involved can skirt around existing regulations and also, use certain regulations to construct new ones. The innovative regulations that enter into application are qualified as being “joint”, since they stem from the efforts of the parties in catering and in agriculture to agree about how to organize transactions, which had previously been done through the work of market middlemen. In that case, instead of reasoning in terms of a pre-existing supply and demand, we have to understand how supply and demand gradually take shape through the process of working out regulations.     

La dynamique de la vocation : les évolutions de la rationalisation de l’engagement au travail des danseurs de ballet

The commitment to one's work, with body and soul involvement is a key issue in the study of vocation-driven occupations. In such callings, the aspirations that are socially constructed and experienced as vocations have been shown to provide meaning and direction to one's commitment. However, this study of Paris Opera ballet dancers shows that realizing one's aspirations are impossible to achieve does not necessarily result in quitting, nor retraining. Changes in the way dancers relate to their work are studied using sequential analysis, to examine which social factors may explain how this involvement's meaning is maintained. The analysis identifies some processes of vocation recomposition. Thus revealing, behind the professional careers, the “moral careers” of the vocation.     

Anticiper ou temporiser : injonctions environnementales et recompositions des identités professionnelles en céréaliculture

Questions about the modernization of farming, given its environmental impact, are leading French farmers to rework their occupational identities. This is studied by comparing cereal growers who practice “integrated protection” — a form of agriculture that saves on input — with their “conventional” colleagues. Given the high degree of uncertainty about the standards that will be imposed, cereal farmers have adopted positions that contrast with regard to: the future (anticipating vs. stalling for time), “professional excellence” (whether or not to accept lower yields) and risks (whether to adopt strategies turned toward vigilance or toward insurance). The diffusion of innovative farming practices is limited owing to their lack of legitimacy, which leads farmers to explore the possibilities for obtaining legitimation from outside the profession.
