Chain ratio type estimator for ratio of two population m3ans using auxiliary characters

In this paper we have proposed chain ratio type estimators for ratio of two population means using two auxiliary characters. The expressions for bias and mean square error of these estimators have been derived. A comparison of the proposed estimator with that of double sampling estimator has been made in terms of mean square error. An emperical study has also been made.     

Knowledge transfer of the Western concept of quality

This paper addresses one of the issues in contemporary globalization theory: the extent to which there is 'one best way' in which business can be conducted and organizations managed. It uses Czarniawska's 'travels of ideas' model as an organizing framework to present and understand how the concept of 'quality', so important in contemporary approaches to manufacturing and services, and their management, travelled to, and impinged on, a newly opened vehicle assembly plant in Poland. The extent to which new meanings were mutually created in the process of translation is discussed, using ethnographic reporting and analysis techniques commonly used in diffusion research. Parallels between the process of translation as an idea becomes embedded into a new cultural location and the processes which contemporary research has identified as important to organizational learning are briefly discussed in conclusion.     

儒家道德修养论与社会主义核心价值体系建构

儒家道德修养论强调个体修养的自觉性和主动性,提倡内省、内讼、慎独、居敬穷理、省察克治和躬行实践的修养方法,以及内圣外王的修养境界等,在今天仍然具有一定的参考价值。批判地继承儒家道德修养论的合理因素,为社会主义核心价值体系建构提供有效的实践路径和方法论借鉴：提倡德性养成,把社会主义核心价值体系理论转化为全民的德性;注重知行结合,把对社会主义核心价值体系的认识转化为全民的自觉行为;树立先进价值典范,引导人民群众践行社会主义核心价值体系。     

Acceleration of the Multiple-Try Metropolis algorithm using antithetic and stratified sampling

The Multiple-Try Metropolis is a recent extension of the Metropolis algorithm in which the next state of the chain is selected among a set of proposals. We propose a modification of the Multiple-Try Metropolis algorithm which allows for the use of correlated proposals, particularly antithetic and stratified proposals. The method is particularly useful for random walk Metropolis in high dimensional spaces and can be used easily when the proposal distribution is Gaussian. We explore the use of quasi Monte Carlo (QMC) methods to generate highly stratified samples. A series of examples is presented to evaluate the potential of the method.     

Markov Chain Monte Carlo in small worlds

As the number of applications for Markov Chain Monte Carlo (MCMC) grows, the power of these methods as well as their shortcomings become more apparent. While MCMC yields an almost automatic way to sample a space according to some distribution, its implementations often fall short of this task as they may lead to chains which converge too slowly or get trapped within one mode of a multi-modal space. Moreover, it may be difficult to determine if a chain is only sampling a certain area of the space or if it has indeed reached stationarity. In this paper, we show how a simple modification of the proposal mechanism results in faster convergence of the chain and helps to circumvent the problems described above. This mechanism, which is based on an idea from the field of “small-world” networks, amounts to adding occasional “wild” proposals to any local proposal scheme. We demonstrate through both theory and extensive simulations, that these new proposal distributions can greatly outperform the traditional local proposals when it comes to exploring complex heterogenous spaces and multi-modal distributions. Our method can easily be applied to most, if not all, problems involving MCMC and unlike many other remedies which improve the performance of MCMC it preserves the simplicity of the underlying algorithm.

理性批判推动科学进步--浅探波普的科学知识增长论

如何才能促进知识的增长呢?波普强调理性的批判精神是推动科学知识增长和进步的最大动力。他认为任何理论都是一种“假设”或“猜测”,只有在反驳中才能得到进步。他提出了反归纳法、证伪原则和“猜测与反驳”的知识增长模式。他的科学方法论弥补了逻辑经验主义的某些不足,同时也带有机械性和脱离科学发展的倾向。
