Development of an expert system for abnormal operating procedures in a main control room

The study was conducted from the perspective of human factors engineering in order to compare the process that operators originally used to diagnose potential and actual faults with a process that included an expert system for diagnosing faults. The results of the study indicated that the existence of an expert system for fault diagnosis makes the task of fault diagnosis easier and reduces errors by quickly suggesting likely Abnormal Operating Procedures (AOPs).

Semi-parametric hybrid empirical likelihood inference for two-sample comparison with censored data

Two-sample comparison problems are often encountered in practical projects and have widely been studied in literature. Owing to practical demands, the research for this topic under special settings such as a semiparametric framework have also attracted great attentions. Zhou and Liang (Biometrika 92:271–282, 2005) proposed an empirical likelihood-based semi-parametric inference for the comparison of treatment effects in a two-sample problem with censored data. However, their approach is actually a pseudo-empirical likelihood and the method may not be fully efficient. In this study, we develop a new empirical likelihood-based inference under more general framework by using the hazard formulation of censored data for two sample semi-parametric hybrid models. We demonstrate that our empirical likelihood statistic converges to a standard chi-squared distribution under the null hypothesis. We further illustrate the use of the proposed test by testing the ROC curve with censored data, among others. Numerical performance of the proposed method is also examined.     

China's demographic dilemmas

The year 2000 marks the end of a tumultuous century in China's population history, which weathered the demographic effects of devastating famines, wars, and epidemics and population growth and change. This paper examines the effect of population policies on the demographic dilemmas of China. In the 1950s, China had seen the fastest demographic transition in history, with a dramatic decline in mortality rates, followed by a decrease in fertility rates. However, in the 1970s, revisions in population control measures, changes in age structure, and fluctuations in age at marriage resulted in lower fertility rates. The struggles encountered by China in regulating fertility are described; these include the different methods of birth control, gender preference, marriage, population aging, and minority populations. Population and development issues within the context of urbanization, employment, education, health care, economy, and environment are also discussed. Future implications of these findings indicate the need for a systematic, effective, and complete environmental clean-up, as well as fertility and population policies.     

基于心理契约视角的顾客满意管理研究

随着市场竞争的不断加剧,企业从关注产品转向关注顾客,关注并提升顾客满意成为现代企业市场竞争的关键。要吸引顾客,留住顾客,最基本的条件就是要了解他们的需求,了解他们的期望,这样才能制定相应的策略和制度,使顾客感到满意。因此,从心理、情感和关系层面切入来满足顾客、维系顾客的忠诚就有着特殊的意义,心理契约的引入为此提供了全新的视角。     

社区治理中的集体消费——以特大城市的三个基层社区为例

文章从理论和三个案例出发,分析了城市社区集体消费存在的问题,认为缺乏有效的集体消费组织和管理机制是导致基层社区治理失序的主要因素.在此基础上,文章提出基层政权的核心责任之一是组织和管理集体消费.中国的所有制形式、居住方式和集团消费模式决定了集体消费问题必然长期存在,如果这一问题得不到有效的解决,将会为发展埋下隐患.     

整合大众财富观的哲学思考

现实社会是计划经济财富观、中国传统文化财富观、市场经济财富观、西方资产阶级财富观和社会主义市场经济财富观等五种财富观并存,社会主义市场经济财富观的主导地位还在树立之中。要对影响大众的各种财富观进行梳理,分析这些财富观所产生的实际影响和得以流行的社会原因,明确要肯定怎样的财富观、否定怎样的财富观和倡导怎样的财富观,努力促进社会主义市场经济财富观在全社会确立主导地位。     

ESTIMATION AND TESTING FOR PARTIALLY LINEAR SINGLE-INDEX MODELS

In partially linear single-index models, we obtain the semiparametrically efficient profile least-squares estimators of regression coefficients. We also employ the smoothly clipped absolute deviation penalty (SCAD) approach to simultaneously select variables and estimate regression coefficients. We show that the resulting SCAD estimators are consistent and possess the oracle property. Subsequently, we demonstrate that a proposed tuning parameter selector, BIC, identifies the true model consistently. Finally, we develop a linear hypothesis test for the parametric coefficients and a goodness-of-fit test for the nonparametric component, respectively. Monte Carlo studies are also presented.
