Kernel Estimation of Rate Function for Recurrent Event Data

Abstract.  Recurrent event data are largely characterized by the rate function but smoothing techniques for estimating the rate function have never been rigorously developed or studied in statistical literature. This paper considers the moment and least squares methods for estimating the rate function from recurrent event data. With an independent censoring assumption on the recurrent event process, we study statistical properties of the proposed estimators and propose bootstrap procedures for the bandwidth selection and for the approximation of confidence intervals in the estimation of the occurrence rate function. It is identified that the moment method without resmoothing via a smaller bandwidth will produce a curve with nicks occurring at the censoring times, whereas there is no such problem with the least squares method. Furthermore, the asymptotic variance of the least squares estimator is shown to be smaller under regularity conditions. However, in the implementation of the bootstrap procedures, the moment method is computationally more efficient than the least squares method because the former approach uses condensed bootstrap data. The performance of the proposed procedures is studied through Monte Carlo simulations and an epidemiological example on intravenous drug users.

翻译:意识形态的建构、解构、重建与解读

翻译不仅是语言之间信息转换的文化活动,而且是一系列复杂的思维活动。意识形态以不同的语言形式隐藏在语篇之中,以各种隐蔽方式潜移默化地影响着作者写作、译者翻译以及读者解读文本。本文拟以批评语言学为主要方法论,强调翻译中语言分析和社会分析相结合的重要性,同时主张翻译研究应以语篇为单位,特别注意考察作者、译者、读者在翻译过程中的三元关系及其在意识形态的建构、解构、重建和解读过程中的作用,以便弄清翻译的本质并有效地解释那些"不忠"的现象。     

诗谶说的文学批评价值

诗谶是鉴诗者将诗歌作品与诗人或相关人物命运相结合,以求诗歌与史实或本事互相印证的一种诗歌批评形式.它包含着兴亡谶、穷通谶(科谶与仕谶)、贫富谶、寿亡谶、祸福谶等内容,是汉儒以谶解诗、诗学与命理学结合的产物,虽然披上了宿命论外衣,却汲取并深化了古代诗论的言志言情、知人论世、诗可以观、气象观诗说等多方面的内在精神.正确评价诗谶对批评地接受传统诗学遗产是十分必要的.     

Deconvolution with supersmooth distributions

Nonparametric deconvolution problems require one to recover an unknown density when the data are contaminated with errors. Optimal global rates of convergence are found under the weighted L_p-loss (1 ≤ p ≤ ∞). It appears that the optimal rates of convergence are extremely low for supersmooth error distributions. To resolve this difficulty, we examine how high the noise level can be for deconvolution to be feasible, and for the deconvolution estimate to be as good as the ordinary density estimate. It is shown that if the noise level is not too high, nonparametric Gaussian deconvolution can still be practical. Several simulation studies are also presented.     

黑龙江省工业资本产出贡献率的实证分析

提高老工业基地的经济增长水平,是一个意义深远的课题。黑龙江省老工业基地发展相对落后的原因在于工业实收资本结构的不合理,国家资本偏高,个人资本绝对性偏低,单位个人资本效率是单位国家资本的五倍。法人资本的多层代理也是造成黑龙江省工业发展相对落后的原因之一。对此,应妥善解决委托代理失灵问题,大力促进民营资本的发展,加快国有经济布局的战略性调整。

Can we remember differently? A case study of the new culture of memory in voluntary organisations

This article analyses the positive contribution that Slovenian voluntary, non–governmental organisations, users' organisations and community–based services in the field of mental health have made to the 'new culture of memory' of helpers and users. The conceptual differences between Slovenian psychiatric (institutional) treatment and voluntary community care are presented through the case study of Clare, a young woman who was diagnosed as a chronic schizophrenic. This example shows the importance of community care in voluntary organisations for the reduction of disability associated with mental disorders. The development of the new culture of memory in voluntary organisations and community–based services is not only the 'narrative turn' within social welfare, but also symbolises the 'implicit turn' in the relationship between the helper and the user. The real challenge of the new culture of memory in the process of help to disabled people (in respect of individuals working through traumatic memories) is that the helper can bear and support the user on a daily basis. During the process of their relationship, the deep implicit relational memories of both become activated and influence the change within the user as well as the helper.     

The Boston Area Diary Study and the Moral Citizenship of Care

This paper describes the theoretical foundations, empirical findings, and practical and philosophical implications of the Boston Area Diary Study (BADS), a study of the caring behavior of 44 participants over one calendar year. In particular, the paper presents an identification theory of care and discusses how it shaped the conceptualization, collection, and analysis of the data in a year-long diary study of daily voluntary assistance. The findings from the BADS (1) theoretically confirm the identification theory of care; (2) methodologically capture how individuals perceive and carry out caring behavior as a unity; and (3rpar; empirically document the existence of a moral citizenship in America that is substantially more vigorous than is implied by the usual indicators of civic and political citizenship.
