Collective versus Individual Effects in Survival Analysis of Multiple Failures

In survival analysis, we sometimes encounter data with multiple censored outcomes. Under certain scenarios, partial or even all covariates have ‘similar’ relative risks on the multiple outcomes in the Cox regression analysis. The similarity in covariate effects can be quantified using the proportionality of regression coefficients. Identifying the proportionality structure, or equivalently whether covariates have individual or collective effects, may have important scientific implications. In addition, it can lead to a smaller set of unknown parameters, which in turn results in more accurate estimation. In this article, we develop a novel approach for identifying the proportionality structure. Simulation shows the satisfactory performance of the proposed approach and its advantage over estimation under no assumed structure. We analyse three datasets to demonstrate the practical application of the proposed approach.     

改革开放对中国民族主义话语体系变迁影响研究

改革开放四十多年来,全球化和民族国家发展之间的张力是中国民族主义话语体系变迁的主要动力,一方面中国要融入世界,应对来自国际社会的挑战,另一方面中国也要关注现代国家建构过程中国内的社会、民族矛盾,这种双重压力促使中国民族主义的话语体系和研究范式发生了转变,即从民族主义到人类命运共同体。中国民族主义的话语体系是新时代中国特色社会主义话语体系的重要组成部分,它部分回应了国际社会对中国发展道路的关切和中国在全球化治理中对自身的定位和国际担当。实践证明,人类命运共同体理论在思维方式、价值观、文明观、国际秩序观等多个方面实现了对原有的民族主义话语体系和研究范式的超越和重构,成功回应了全球化和民族国家发展之间的张力关系。     

曹雪芹的无神论思想——兼论高鹗的神权观

曹雪芹的无神论思想在《红楼梦》前八十回中有大量体现,其中虽然写了许多神仙的故事,但是这些神仙的名字都叫茫茫大士,渺渺真人,空空道人,警幻仙姑;而地名则叫大荒山,无稽压,太虚幻境等等.曹的用意十分明确:这些不过是渺、茫、空、幻,荒诞的无稽之谈,属于"贾(假)语村言",和此书不记何年何代,地点可南可北一样,都是为了给此书蒙上一层虚无飘渺的色彩,以掩盖其现实严肃的政治内容.曹雪芹虽写了一系列神话故事,但一写到现实的和尚,尼姑,道士,道婆一类人物,大都采取揭露和批判的态度.与高鹗在后四十回中大量传播神权和因果报应得封建迷信思想,形成鲜明的对比.     

Writing resistance together

This piece of writing is a joint initiative by the participants in the Gender, Work and Organization writing workshop organized in Helsinki, Finland, in June 2019. This is a particular form of writing differently. We engage in collective writing and embody what it means to write resistance to established academic practices and conventions together. This is a form of emancipatory initiative where we care for each other as writers and as human beings. There are many author voices and we aim to keep the text open and dialogical. As such, this piece of writing is about suppressed thoughts and feelings that our collective picket line allows us to express. In order to maintain the open‐ended nature of the text, and perhaps also to retain some ‘dirtiness’ that is essential to writing, the article has not been language checked throughout by a native speaker of English.     

经济全球化背景下的中国地方政府转型与职能定位

中国从1978年推行对外开放政策以来,一改过去那种被动纳入全球化的方式,开始以一种积极的姿态主动地参与到世界经济全球化的进程中来,不仅极大地促进了中国经济社会的迅猛发展,而且也在很大程度上推动了中国政府,特别是各级地方政府以提供公共服务为目标的政府转型,进而导致中国地方政府职能的全新定位。     

环境运动促进生态和谐与社会和谐的现实结合

构建社会主义和谐社会,是中国共产党提出的一个崭新的命题,是一项重大的战略决策。如何将生态和谐现实地融入到整个社会和谐的体系之中,是当前我们所面临的重大问题。其中民间机制尤其是环境运动在这方面的作用是不容忽视的,它通过对政府机制的补充,有效地促使了生态和谐现实地融入到社会和谐的整体中。

Uniform consistency rate of kNN regression estimation for functional time series data

In this paper, we investigate the k-nearest neighbours (kNN) estimation of nonparametric regression model for strong mixing functional time series data. More precisely, we establish the uniform almost complete convergence rate of the kNN estimator under some mild conditions. Furthermore, a simulation study and an empirical application to the real data analysis of sea surface temperature (SST) are carried out to illustrate the finite sample performances and the usefulness of the kNN approach.     

对文化创意产业标准化战略的思考

标准具有技术与制度双重属性.文化创意产业要做到“文化和科技融合,发展新型业态、实现创意产业的规模化、集约化、专业化”,政府和企业必须重视文化创意产业的标准化战略,构建我国文化创意产业分类和统计标准、文化创意企业和聚集区分类标准、文化产品和服务的技术标准等三大类标准.文化创意产业的标准化作为一种超越产品、专利、品牌竞争的高层次竞争手段,在其产业发展中的作用越来越重要.专利和品牌是对一种产品的垄断,标准是对一个行业的垄断,得标准者得天下.
