GMM tests for the Katz family of distributions

Generalized method of moments (GMM) is used to develop tests for discriminating discrete distributions among the two-parameter family of Katz distributions. Relationships involving moments are exploited to obtain identifying and over-identifying restrictions. The asymptotic relative efficiencies of tests based on GMM are analyzed using the local power approach and the approximate Bahadur efficiency. The paper also gives results of Monte Carlo experiments designed to check the validity of the theoretical findings and to shed light on the small sample properties of the proposed tests. Extensions of the results to compound Poisson alternative hypotheses are discussed.     

剑溪堂刻本《书经》考述

剑溪堂刻本《书经》为近年在徽州地区发现的一种《尚书》新版本。根据其书口、版式、字体、用纸、内封面以及避讳等情况综合判断,该书刊行于明神宗万历年间,与北图藏元明间宗文书堂刻本《书集传音释六卷》同出一个版本系统。它的出现对于认识《书经》乃至整个《尚书》的流变史有其重要意义。在蔡沈集传《书经》普遍流行六册、七册线装本的情况下,三册毛装本无疑还具有较强的版本认识价值。     

高校辅导员职业的专业划分问题研究

高校辅导员是否是一种职业，该不该划分专业，划分专业的标准是什么，具体由哪些专业构成，这些问题是高校辅导员专业化问题讨论中必须回答的问题。这些问题，有的理论界已有所探讨，但存在较大分歧，有的还未引起足够的重视。本文就此谈谈我们初浅的认识。     

Les transformations de l'intégration par l'emploi: Regards croisés : France métropolitaine - île de La Réunion

Against a background of mass unemployment and the increasing precariousness of employment, the current changes in the labour market demand that we examine the previously central role of paid employment in social integration. If the individual now deprived of employment or having a temporary contract is by dint of this fact less included in society or is less secure by not having a permanent salary, is it to say that he embodies the face of the de-affiliated, of those who miss out on social benefits? Taking the example of the Reunion Island which has the highest level of unemployment and population covered by the minimum income (RMI: Revenu Minimum d'Insertion) in the country, this article endeavours to explain and understand how, in the context of a protective society and increasingly flexible employment market, new methods of social integration without and resulting from paid employment are being formed.     

东北抗日义勇军入新后对新疆社会的影响

“九·一八”事变后，东北军民组成抗日义勇军与日军进行了殊死搏斗，最后被迫退出东北，取道苏联，来到新疆。他们为稳定新疆政局、新疆军事的近代化、新疆经济文化的发展等作出了贡献，对新疆社会产生广泛影响。     

从对抗、依赖到利用的性别修辞——由女性小说的解读透视女性生存

女性文学在当代中国的发展历程由80年代的强调女性自立、男女平等等造成了新的性别困惑和压迫，到90年代的张扬性别意识、身体写作导致女性的物化，再到90年代末盛行的“小女人散文”的巧用自身优势去赢得社会认同。拟从这些具有典型意义的文本中透视女性的生存，从而给现实生活中的女性一些启示——积极利用自身优势去获得发展的机会。     

“五四”后期周建人的婚恋观——以《妇女杂志》为考察依据

周建人在五四后期在恋爱、婚姻、离婚问题上更多地注重个体的自由、价值和觉醒。他认为，真诚的恋爱本是人生的花，是精神的高尚产品；理想的配偶选择应以个人本身性质上的各种美德为标准：以爱情的有无为婚姻离合的原则。婚恋的个人自由和独立有利于种族的完善、国家的进步，也是妇女解放和冲破家族制度的重要手段。因此，其婚恋观的一个重要诉求是男女平等，呈现出对妇女解放各个问题理性而具体的思考。

Geometric Method and Generalized Linear Models. Two Opposite Multiparametric Approaches Illustrated on a Sample of Pituitary Adenomas

We used two statistical methods to identify prognostic factors: a log-linear model (logistic and COX regression, based on the notions of linearity and multiplicative relative risk), and the CORICO method (ICOnography of CORrelations) based on the geometric significance of the correlation coefficient. We applied the methods to two different situations (a "case-control study' and a "historical cohort'). We show that the geometric exploratory tool is particularly suited to the analysis of small samples with a large number of variables. It could save time when setting up new study protocols. In this instance, the geometric approach highlighted, without preconceived ideas, the potential role of multihormonality in the course of pituitary adenoma and the unexpected influence of the date of tumour excision on the risk attached to haemorrhage.     

Les agriculteurs dans la fabrique d'une nouvelle agriculture

The model of development that has governed the modernization of farming in France is increasingly coming under attack. Given this, analysing the “work” that farming performs to “translate” the criticisms with which it must cope in formulating new definitions of roles is important in order to understand changes under way in this sector. The changes undergone by farming over the past eighty years are briefly presented and then the procedures and results of a survey, conducted during the mad cow disease among beef-farmers in Burgundy, are described. Light is thus shed on the diversity of the positions that farmers have adopted with regard to the future of their occupation. An interpretation is proposed of how the distribution (and interplay between) these positions might affect agriculture. - Special issue on Agriculture and food.
