Varying-coefficient single-index measurement error model

This paper proposes a varying-coefficient single-index measurement error model, which consists of measurement error in the index covariates. We combine the simulation-extrapolation technique, the local linear regression and the weighted least-squares method to estimate the unknowns of the current model, and develop the asymptotic properties of the resulting estimators under some conditions. A simulation study is conducted to evaluate the proposed methodology, and a real example is also studied to illustrate our given methodology.     

Exploitation of a crisp relation in a ranking problem

The outranking methods usually contain two main steps: determination of a (sometimes valued) relation which aggregates the preferences and exploitation of this relation in order to choose, sort or rank the actions. In a ranking problem, the second step is the construction of a (complete or partial) preorder from a (valued) relation. We have considered it was interesting to list the good properties such a construction should verify and to analyze some procedures in this context. We present here the first results of this study, which concern the construction of a complete preorder from a non valued relation.     

试析"非物质文化遗产"的基本特点与性质

非物质文化遗产与自然遗产、世界文化遗产、传统民族民间文化遗产、文化景观遗产既有联系,又有区别。论者主要从非物质文化遗产与其他类型遗产的区别中,提出并分析了非物质文化遗产的独特性、活态性、传承性、变异性、综合性、民族性和地域性等基本特点,以及其他特点。同时,论者还结合中国的国情分析了非物质文化遗产的性质,并建议据此制定相关政策、进行保护非物质文化遗产的实践活动。     

A new class of distribution having decreasing,increasing, and bathtub-shaped failure rate

In this article, we propose a new class of distribution which is based on the concept of exponentiated generalization with some modification so as to provide a better result in terms of flexibility. Our proposed distribution accommodates various shapes of hazard rate including the bathtub. Exponential distribution has been taken as the baseline distribution. Various statistical properties of the proposed distribution have been studied. We have used the method of maximum likelihood for estimation of the parameters of the proposed model. Last, we have analyzed four real datasets to illustrate the flexibility of the model in comparison to eight existing well-known distributions.     

An extended exponentiated-G-negative binomial family with threshold effect

In this paper, we formulate a very flexible family of models which unifies most recent lifetime distributions. The main idea is to obtain a cumulative distribution function to transform the baseline distribution with an activation mechanism characterized by a latent threshold variable. The new family has a strong biological interpretation from the competitive risks point of view and the Box–Cox transformation provides an elegant manner to interpret the effect on the baseline distribution to obtain this alternative model. Several structural properties of the new model are investigated. A Bayesian analysis using Markov Chain Monte Carlo procedure is developed to illustrate with a real data the usefulness of the proposed family.     

重思 “解释世界” 与 “改变世界” 的经典命题

马克思 《关于费尔巴哈的提纲》 第十一条在学界引发了诸多争论, 其焦点在于如何理解 “哲 学家们” 的指涉对象、 马克思是否放弃 “解释世界” 的理论诉求以及 “解释世界” 与 “改变世界” 之间存 在何种关系的问题。 在笔者看来, 探讨 “哲学家们” 的指涉对象理应自觉置于马克思创作 《关于费尔巴哈 的提纲》 的学术背景和时代环境进行考察, 马克思视域中的 “哲学家们” 实际上具体指向某一类人; 在是 否放弃 “解释世界” 的诉求上, 马克思确实舍弃了哲学性质维度的 “解释世界”, 但并没有完全放弃哲学认 知意义上的 “解释世界”; 在 “解释世界” 与 “改变世界” 的关系上, 要结合马克思的思想发展进程以及哲 学观变革的意义予以整体审视。 在新的时代背景下, 重思 《关于费尔巴哈的提纲》 第十一条, 对继承与发 扬马克思的实践哲学精神及其价值旨趣具有重要意义。
