Maurice Allais 《Theory and Decision》1995,38(3):251-299
1.-The Impossibility Theorem rests on five fundamental properties. On each of them Machina has confirmed his agreement over and over again between 1984 and 1986. The proof of the Impossibility Theorem is mathematically and rigorously correct.2.- The alleged Machina's demonstration of the Allais' two errorsis indeed only grounded on a series of errors and it isin total contradiction with the interpretationsexplicitly given by Machina from 1982 to 1986 of his local utility theory in the discrete case, especially in his letters.3.1 In fact one cannot but ask if Machina really understands the meaning and the implications of his formulation of the local utility, and what is really in question.In any case it would he without any doubt eminently desirable that before hastily concluding that the others are making mistakes, Machina should begin by seriously asking himself if he is not himself into error. 相似文献

In this study, we investigate to what extent macro-economic circumstances and social protection expenditure affect economic deprivation. We use three items from round five of the European Social Survey (2010–2011) to construct our latent outcome variable, which we label economic deprivation in the 3 years before 2010–2011. The results of our linear multilevel regression analyses indicate that in countries that perform worse economically, individual experiences of economic deprivation are more prevalent: the stronger the rise in the unemployment rate and the lower a country’s wealth, the more economic deprivation individuals experience. We also find that in countries with high levels of social protection, people experience less economic deprivation as compared to countries with low levels of social protection. In turn, adverse economic conditions in a country temper these positive outcomes of social welfare arrangements. Finally, our study reveals that the strength of the relationship between a low income and economic deprivation strongly varies according to the economic circumstances in a country and the generosity of the welfare state. 相似文献

In the past decade, the People’s Republic of China has become the leading source country of immigrants to Canada. However, little is known about the experience of Chinese gay immigrants in Canada. Using narratives collected through a qualitative study, we show the way in which Chinese gay men construct their experience of immigration in Canada. Unlike the national discourse that claims Canada is a friendly nation for members of the LGBTTQ community, the experiences of Chinese gay immigration present a different story. As racialised gay men, they continue to be subjected to social violence in Canada – albeit differently from what they experienced in China. The analysis demonstrates the complexity of social marginalisation experienced by these men, the understanding of which is essential for social workers to engage in practice with them that is socially transformative. 相似文献

Early maternal resolution with preterm birth was assessed at one month corrected age (CA), and potential maternal and infant characteristics that may be associated with early resolution were examined. Fifty‐five mothers of preterm infants (≤34 weeks) participated. Data regarding pregnancy, prenatal risk, delivery, infant's medical risk, maternal well‐being status, and infant's early developmental status were collected. Resolution was examined using the Reaction to Diagnosis Interview (RDI). A total of 38.2% of the mothers were classified as resolved. Only completion of antenatal corticosteroids (ACS) treatment and high prenatal risk significantly predicted maternal resolution. Early maternal resolution of preterm birth is associated with early knowledge regarding the preterm birth. 相似文献
