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.     

Bayesian t-tests for correlations and partial correlations

In this paper, we develop Bayes factor based testing procedures for the presence of a correlation or a partial correlation. The proposed Bayesian tests are obtained by restricting the class of the alternative hypotheses to maximize the probability of rejecting the null hypothesis when the Bayes factor is larger than a specified threshold. It turns out that they depend simply on the frequentist t-statistics with the associated critical values and can thus be easily calculated by using a spreadsheet in Excel and in fact by just adding one more step after one has performed the frequentist correlation tests. In addition, they are able to yield an identical decision with the frequentist paradigm, provided that the evidence threshold of the Bayesian tests is determined by the significance level of the frequentist paradigm. We illustrate the performance of the proposed procedures through simulated and real-data examples.     

State transition modeling of complex monitored health data

This article considers the analysis of complex monitored health data, where often one or several signals are reflecting the current health status that can be represented by a finite number of states, in addition to a set of covariates. In particular, we consider a novel application of a non-parametric state intensity regression method in order to study time-dependent effects of covariates on the state transition intensities. The method can handle baseline, time varying as well as dynamic covariates. Because of the non-parametric nature, the method can handle different data types and challenges under minimal assumptions. If the signal that is reflecting the current health status is of continuous nature, we propose the application of a weighted median and a hysteresis filter as data pre-processing steps in order to facilitate robust analysis. In intensity regression, covariates can be aggregated by a suitable functional form over a time history window. We propose to study the estimated cumulative regression parameters for different choices of the time history window in order to investigate short- and long-term effects of the given covariates. The proposed framework is discussed and applied to resuscitation data of newborns collected in Tanzania.     

Quasi-binomial zero-inflated regression model suitable for variables with bounded support

In recent years, a variety of regression models, including zero-inflated and hurdle versions, have been proposed to explain the case of a dependent variable with respect to exogenous covariates. Apart from the classical Poisson, negative binomial and generalised Poisson distributions, many proposals have appeared in the statistical literature, perhaps in response to the new possibilities offered by advanced software that now enables researchers to implement numerous special functions in a relatively simple way. However, we believe that a significant research gap remains, since very little attention has been paid to the quasi-binomial distribution, which was first proposed over fifty years ago. We believe this distribution might constitute a valid alternative to existing regression models, in situations in which the variable has bounded support. Therefore, in this paper we present a zero-inflated regression model based on the quasi-binomial distribution, taking into account the moments and maximum likelihood estimators, and perform a score test to compare the zero-inflated quasi-binomial distribution with the zero-inflated binomial distribution, and the zero-inflated model with the homogeneous model (the model in which covariates are not considered). This analysis is illustrated with two data sets that are well known in the statistical literature and which contain a large number of zeros.     

试论《莱茵报》时期马克思新闻报刊思想中的人民性

试图通过对《马克思恩格斯全集》中一些著名章节的回顾来讨论人民性在《莱茵报》时期马克思新闻报刊思想中的体现。论述分为三部分：首先回顾马克思对于人民报刊在当时受到的指责做出的一些辩护,并由此出发解读报刊的人民性;接下来借用西方哲学中“程序正义和实质正义”的标准分析马克思对于新闻政策———尤其是书报检查政策———的主要见解;最后是对于不断壮大的人民队伍中存在的内部矛盾在新闻报刊事业中的体现的几点思考。     

Not Ethnic Enough: The Cultural Identity Imperative in International Adoptions from China to Canada

Based on a qualitative research of adoptions from China to Canada, this article analyses changing attitudes and approaches to racial and ethnic differences in adoptive kinship in the last few decades. I argue that culture celebration labour over children adopted from China is shaped by the contemporary Canadian culturalist ethos, the Orientalist imagination, and the Asian model minority stereotype. The cultural identity imperative, a core component of multicultural governmentality, perceives culture as an object, demands non‐white Canadian subjects with rooted belongings, and operates in ways that sanctions and incorporates, as it depoliticises and subordinates.     

Conditions for Exercising Residents’ Voting Rights in Long-Term Care Residences: A Prospective Multicenter Study

To assess voting conditions in long-term care settings, we conducted a multicenter survey after the 2009 European elections in France. A questionnaire about voting procedures and European elections was proposed in 146 out of 884 randomized facilities. Sixty-four percent of facilities answered the questionnaire. Four percent of residents voted (national turnout: 40%), by proxy (58%) or at polling places (42%). Abstention related to procedural issues was reported in 32% of facilities. Sixty-seven percent of establishments had voting procedures, and 53% declared that they assessed residents’ capacity to vote. Assistance was proposed to residents for voter registration, for proxy voting, and for voting at polling places, respectively, in 33%, 87%, and 80% of facilities. This survey suggests that residents may be disenfranchised and that more progress should be made to protect the voting rights of residents in long-term care facilities.     

Essential Conditions for Research with Children with Autism: Issues Raised by Two Case Studies

This article discusses conditions for research into the social experiences of children with autism in real‐life contexts using material from case studies of two boys with autism and their friends in mainstream school settings. It is argued that essential conditions for research with children with autism in ordinary social contexts should include a participatory approach, take a wide perspective of group processes, and account for multiple influences on social behaviour. Socially focused, participatory research design allows the social competencies that children with autism do have to be seen and produces multiple perspectives on children's social activity. Children and adults thinking together and sharing their ideas about the nature of experience for a child with autism and their friends allows for shared interpretations and reduces the very real possibility of one researcher alone making wrong assumptions about the nature of the investigation.
