Erratum to “Progressively Type-II right censored order statistics from discrete distributions” [J. Statist. Plann. Inference 138 (2008) 845–856]

In this note, we correct the proof of Representation 1 of Balakrishnan and Dembińska [2008. Progressively Type-II right censored order statistics from discrete distributions. J. Statist. Plann. Inference 138, 845–856] which relates the joint distribution of progressively Type-II right censored order statistics corresponding to an arbitrary population to progressively Type-II right censored order statistics from the standard uniform distribution.     

恒生的新“度量衡” 将A-H股溢价推向何方？

由于市场分割、计价货币、投资环境、投资理念、需求价格弹性差异等各种主客观原因，导致同一公司A股和H股的同股不同价现象。随着恒生AH股溢价指数的推出，衍生产品发行商为投资者开发利用价差套利的新产品就更加容易了，这无疑为两地股市套利交易铺平道路，从长远看，A、H股的价差将逐步缩小并可能消失。     

Burden of bioinformatics in medical research: Statistical perspectives and controversies

The ongoing evolution of genomics and bioinformatics has an overwhelming impact on medical and clinical research, albeit this development is often marked by genuine controversies as well as lack of scientific clarities and acumen. The search for disease genes and the gene–environment interaction has drawn considerable interdisciplinary scientific attention: environmental health, clinical and medical sciences, biological as well as computational and statistical sciences are most noteworthy. Statistical reasoning (quantitative modeling and analysis perspectives) has a focal stand in this respect while data mining resolutions are far from being statistically fully understood or interpretable. The use of human subjects, though unavoidable, under various extraneous restraints, medical ethics perspectives, and human rights undercurrents, has raised concern all over the world, especially in the developing countries. In the genomics context, clinical trials may be designed on chips and yet there are greater challenges due to the curse of dimensionality perspectives. Some of these challenging statistical issues in medical and clinical research (with emphasis on clinical trials) are appraised in the light of existing statistical tools, which are available for less complex clinical research problems.     

严复与斯宾塞、赫胥黎之间的思想关系——一个主要基于伦理学的解读

关于严复与斯宾塞、赫胥黎的思想关系,存在着两种主要观点：一种观点认为,严复在几乎所有的主要问题上都接受了斯宾塞的理论,而另一种观点认为,严复的理论是对斯宾塞和赫胥黎以及中国传统哲学的糅合、折衷。从伦理学的角度对折衷论的论据考察发现,这些论据都难以成立,把严复珀!解为斯宾塞主义者比将其理解为折衷主义者更符合实际。     

Environmental taxation and the double dividend hypothesis in CGE modelling literature: A critical review

Computable general equilibrium (CGE) modelling is a flexible and open way to model the economic systems that allow practitioners to assess the impacts of different policies or external shocks over an economic system. There is some empirical literature dedicated to test the double dividend hypothesis of an environmental tax reform using CGE models. This hypothesis claims that is possible to obtain an improvement of both environmental and economic conditions by imposing an environmental tax and recycling revenues obtained to reduce other pre-existing taxes. This research provides a comprehensive review of this literature including a statistical and a meta-regression analysis. 69 different simulations from 40 studies have been analyzed. 55% of simulations have achieved a double dividend, concluding that although the environmental dividend is almost always achieved, the economic dividend still remains an ambiguous question that needs further research.     

Fiscal rules in a volatile world: A welfare-based approach

It is widely agreed that a fiscal rule should boost discipline and credibility. A rule should also reduce macroeconomic volatility and be easily understood. Toward such ends, a government may run structural surpluses. In so doing, the government accumulates a precautionary cushion of assets on behalf of agents who do not enjoy access to capital markets. As an additional criterion, that level of assets should be bounded. We provide an example of a structural surplus rule that satisfies all such criteria. In our general equilibrium simulations, we show that such a rule benefits credit-constrained consumers but may hurt others.     

Estimation methods for time‐dependent AUC models with survival data

The performance of clinical tests for disease screening is often evaluated using the area under the receiver‐operating characteristic (ROC) curve (AUC). Recent developments have extended the traditional setting to the AUC with binary time‐varying failure status. Without considering covariates, our first theme is to propose a simple and easily computed nonparametric estimator for the time‐dependent AUC. Moreover, we use generalized linear models with time‐varying coefficients to characterize the time‐dependent AUC as a function of covariate values. The corresponding estimation procedures are proposed to estimate the parameter functions of interest. The derived limiting Gaussian processes and the estimated asymptotic variances enable us to construct the approximated confidence regions for the AUCs. The finite sample properties of our proposed estimators and inference procedures are examined through extensive simulations. An analysis of the AIDS Clinical Trials Group (ACTG) 175 data is further presented to show the applicability of the proposed methods.

布洛克:多重视角下的"艺术"概念

布洛克对传统的"艺术"概念从四个层面作了多角度的审视:艺术品是由人的特殊意图造成的;艺术品是对事物的非功利性审视的产物;"艺术惯例"与艺术创新并不矛盾;"艺术"概念具有开放性.布洛克的理论具有理论的包容性与整合力.     

直觉方法与民国学术

民国时期是中西古今交汇、渗透、融合、创新的学术盛世。在学术研究方法上 ,由西方传入的直觉方法与中国传统的直觉方法相衔接、融合而为学者们所关注 ,成为影响这一时期学术的主流方法。注重生命和意境的现代新儒家便是典型代表。他们在对西方非理性主义思想的认同和对“科学万能”的诘难中扬波而起 ,在方法论上强调对生命、生活的感受、体验和体悟。从梁漱溟、张君劢讲非理性的直觉 ,到贺麟讲超理性的直觉 ,再到牟宗三讲智的直觉 ,新儒家都表现出对中西直觉方法的批判、扬弃和融合创新的共同致思趋向。     

伽达默尔对海德格尔历史观的发展

本文概述并分析了海德格尔的历史观，在此基础上指出，伽达默尔的观点是从海德格尔的生存论本体论历史观出发的，但是，他没有完全因循海德格尔的观点，至少在三个方面，他发展了海德格尔的思想。首先，他把重心从此在筹划的未来性转到历史性上；其次，他把此在生存论筹划的单向作用变成了历史传统和解释者之间的相互作用；第三，他提出了“效果历史”原则，并应用到历史观研究中去。总之，他的发展反映了现代精神科学和现代历史哲学的发展趋势
