Pour une approche sociologique de la comptabilité Réflexions à partir de la réforme comptable chinoise

Based on research on state-run companies in China, the reform of Chinese accountancy is examined so as to show the advantages of a sociological approach to accounting. How can bookkeeping interest sociologists? First of all, it has come out of struggles between various parties and addresses social issues. Secondly, it conveys models of reality, in particular of what is and is not a firm. Thirdly, it produces history in that it shapes economic practices and expectations. Finally, there is a high degree of coherence between the bookkeeping system, the form of a firm, the operation of the economy and the management of social questions. These various points turn accountancy into a legitimate subject of study for sociology and provide an interesting approach to analyzing broader phenomena and processes.     

一种基于镜头聚类的视频场景分割方法

为了更好地进行视频信息检索和浏览,提出了一种利用视觉和运动特征来进行场景分割的方法,该方法在把镜头聚类到场景中时,不仅考虑同一场景内镜头的视觉特征相似性,而且还考虑了镜头的运动特征的一致性。此外,为避免过度分割,还提出了一种方法用来合并过度分割出的场景。实验结果表明,这种方法是有效的。     

Les transformations du marché du travail : un éclairage à partir de l’analyse des décalages entre offre et demande dans un système productif localisé

This new look at approaches to the labor market emphasizes that changes observed during the past twenty years are related to trends as much in supply as in demand. Analyzing both these sides is shown to be valuable for understanding the impact on labor market trends and shedding light on the tensions and contradictions between supply and demand. The mechanisms that have come into play during this period are analyzed in a local productive system, namely agribusiness in the lower Rhone valley in the Provence-Alpes-Côte d’Azur Region of France.     

热奈特的类文本理论及其效应

杰拉德·热奈特的类文本理论受到中西方学界的关注与重视,一些学者对该理论进行了一定的补充和修正工作,也有不少学者将其用于文学研究。类文本理论视阈下,文学研究的对象为环绕于文本边缘的类文本要素,如作者的署名、序言、献词、题记、版权页信息等。将作者重新纳入批评视野,类文本理论有效修正了文本理论将文本与作者相割裂的不当做法;将出版商引入批评框架,类文本理论不仅拓展了传统文学批评体系,还起到限制读者过度阐释的目的。同时,类文本理论促进了叙事学的进一步发展,使文学研究从文本中心走向文本边缘,并将文学的内部研究和外部研究相结合,从而推进了文学批评理论的发展。鉴于类文本与文本的互存关系,某些类文本和文本之间的界限模糊不清,它们在具备类文本属性的同时,又不乏文本的属性,而这一特性又恰恰佐证了类文本之于文本而存续的重要性。     

Le télétravail des cadres : entre suractivité et apprentissage de nouvelles temporalités

Telework is often considered to be a means for making life at work and at home more compatible. Why do some wage-earners, in particular white-collar employees, choose it? Do they actually make a choice or simply adopt a solution “for want of anything better” in an organizational context with its limitations? In this case, what factors do they weigh against each other? Once they have opted for telework, how do these white collars manage to adjust their occupational and family lives? Is their aspiration to improve the balance between the two satisfied? Or do they run up against unexpected difficulties? Answers to these questions come out of two studies conducted among white-collar employees in different sorts of telework. Given the absence of institutional regulations governing the relation between life at home and at work, telework, far from leading to a more balanced life, jeopardizes the organization’s collective efficiency.     

Markov random-field models for estimating local labour markets

Summary. This work is motivated by data on daily travel-to-work flows observed between pairs of elemental territorial units of an Italian region. The data were collected during the 1991 population census. The aim of the analysis is to partition the region into local labour markets. We present a new method for this which is inspired by the Bayesian texture segmentation approach. We introduce a novel Markov random-field model for the distribution of the variables that label the local labour markets for each territorial unit. Inference is performed by means of Markov chain Monte Carlo methods. The issue of model hyperparameter estimation is also addressed. We compare the results with those obtained by applying a classical method. The methodology can be applied with minor modifications to other data sets.     

Les rejetés de la modernisation

In Brazil unlike France two very split labour markets co-exist, the formal and the informal. On the formal labor market in Brazil, union rights prevail, and wage-earners are protected unlike in the informal labor market where none of this exists. Raising industry to an international level pushed many wage-earners out of the formal sector during the 1980s. Did they find jobs elsewhere? If so, in which branches of the economy? To provide answers, two files are crossed, their data having been made longitudinal. Dismissed workers’ trajectories from 1989 till 1995 in two branches and two regions are analyzed: the automobile industry in the São Paulo area and the petrochemical industry in the São Salvador (Bahia) area. These career trajectories shed light on how modernization has affected quite different labor markets; it also brings to the foreground the concept of a systemic restructuring of the labor market. — Special issue: Latin America.     

La victime et le policier : point de vue profane et point de vue professionnel sur la délinquance

Comparing surveys of victims with police statistics illustrates the differences between lay and professional views of crime. Victims’expectations and the police handling of cases do not always match. The determinants of victims’ decisions to report incidents to the police are briefly summarised; and the ways the police classify victims’account and handle their complaints, examined. This analysis is based on two sets of data: a victimisation survey of a sample of 10?504 persons aged 15 and older, drawn from the Île-de-France Region; the police statistics corresponding to the same area.     

Bayesian binary segmentation procedure for detecting streakiness in sports

Summary.  When an individual player or team enjoys periods of good form, and when these occur, is a widely observed phenomenon typically called 'streakiness'. It is interesting to assess which team is a streaky team, or who is a streaky player in sports. Such competitors might have a large number of successes during some periods and few or no successes during other periods. Thus, their success rate is not constant over time. We provide a Bayesian binary segmentation procedure for locating changepoints and the associated success rates simultaneously for these competitors. The procedure is based on a series of nested hypothesis tests each using the Bayes factor or the Bayesian information criterion. At each stage, we only need to compare a model with one changepoint with a model based on a constant success rate. Thus, the method circumvents the computational complexity that we would normally face in problems with an unknown number of changepoints. We apply the procedure to data corresponding to sports teams and players from basketball, golf and baseball.     

原子论认识模式之启示

原子论的思维模式古已有之,这种认识模式里有“基本组成部分”和“分割”这样的思维方式和观念。科学发展使人类思维深入到“基本粒子”的层次,在研究微观世界的组成时,我们有必要对原子论思维模式中某些机械的观念进行修正。
