素质教育对教师素质的要求

素质教育的实质就是以教师为代表的高素质的人对学生实施的旨在提高学生综合素质的教育 ,教师素质的高低 ,直接决定着素质教育的成败。可以说 ,素质教育的成效是由教师素质决定的。教师的思想政治素质、道德品行素质、科学文化素质、能力素质、身心素质等是素质教育对教师素质的基本要求。为此 ,各级各类学校要切实加强对教师的培养 ,全面提高他们的素质 ,努力完成培养高素质的人才重任。     

唯物史观视野中的“知识经济”问题

当前西方“知识经济”理论试图用科学知识的创造与应用状况来规定人类发展高阶段的社会文明和历史时代的本质及规律。这与唯物史观从经济基础与上层建筑的统一来定位社会形态和历史时代的原则相去甚远 ,对此我们不能盲目认同 ,但我们也不能对之虚无主义地完全排斥。应该看到 ,“知识经济”问题的研究将会推动我们对马克思主义实践观中科学知识要素的关注 ;将会加深我们对在新的历史时期实施科教兴国战略的理解 ;将会更新我们对知识分子历史地位的认识。这些都将有助于丰富和拓展唯物史观的视野

书院教育的复兴与儒家人格培养

中国高等教育的根本矛盾是求道与学艺的矛盾。近代以来,我国高等教育对西、苏模式的模仿主义以及越来越转向学艺本位的教育理念,导致对大学生的人格培养的轻视与路径匮乏,这都一直为国人所诟病。如何寻求突破发展的瓶颈,建立真正意义上21世纪的中国大学和本土化的高等教育模式,已经成为了当代中国高等教育的重要命题。书院作为悠久历史的中国传统文化教育组织,是中国传统高等教育的代表之一,也是儒家人格培养的重要机制,在港澳台和上海等多地正在悄然复兴。立足当代,如何继承传统和与时俱进,就必须要审视书院教育的办学制度与治学方法,这也才是中国高等教育的出路所在。     

Life satisfaction in China and consumption and income inequalities

This research uses nationally representative data to study how economic resources and inequalities are associated with life satisfaction of Chinese residents. We construct economic resource and inequality measures from expenditure rather than from income, after confirming that expenditure inequality is a better measure in the Chinese context. We find that economic inequalities in general are negatively associated with life satisfaction, and that this association is larger for inequalities in the lower half of the distribution than those in the upper half of the distribution. We further explore the mechanisms under which inequality can be associated with life satisfaction, and find that aspiration is potentially one important channel.     

宏观经济对国债利率期限结构的影响研究

文章用隐因子模型和无套利简约宏观金融模型分别对中国国债收益率曲线进行拟合和预测,发现将宏观因子加入利率期限模型后,国债收益率曲线的长端拟合和预测效果均有提升.经脉冲响应和方差分解分析后发现,CPI增长率主要通过影响短期收益率来影响收益率曲线,而工业增加值增长率主要通过影响长期收益率来影响收益率曲线.此外,简约宏观金融模型可以形成对宏观经济的预测,尤其是对工业增加值增长率的预测较为准确.     

Vine copula constructions of higher-dimensional dependent reliability systems

Copulas have proved to be very successful tools for the flexible modeling of dependence. Bivariate copulas have been deeply researched in recent years, while building higher-dimensional copulas is still recognized to be a difficult task. In this paper, we study the higher-dimensional dependent reliability systems using a type of decomposition called “vine,” by which a multivariate distribution can be decomposed into a cascade of bivariate copulas. Some equations of system reliability for parallel, series, and k-out-of-n systems are obtained and then decomposed based on C-vine and D-vine copulas. Finally, a shutdown system is considered to illustrate the results obtained in the paper.     

Improved likelihood inferences for Weibull regression model

A general procedure is developed for bias-correcting the maximum likelihood estimators (MLEs) of the parameters of Weibull regression model with either complete or right-censored data. Following the bias correction, variance corrections and hence improved t-ratios for model parameters are presented. Potentially improved t-ratios for other reliability-related quantities are also discussed. Simulation results show that the proposed method is effective in correcting the bias of the MLEs, and the resulted t-ratios generally improve over the regular t-ratios.     

The reproductive health indices and sex hormone levels in middle-aged and elderly Chinese men

Objective: The aim of this study was to analyze the age-related recession trajectory of reproductive health indices in middle-aged and elderly Chinese men.

Methods: A population-based cross-sectional study was conducted in Jiashan County, Zhejiang in 2012. Healthy men between 40 and 80 years of age were considered eligible for the study. Physical examination and the sex hormones were measured. The subjects were assessed based on the 5-item version of the International Index of Erectile Function (IIEF-5) for Erectile Dysfunction (ED), and Aging Males’ Symptoms (AMS) scale for Symptomatic Late-Onset Hypogonadism (SLOH).

Results: TG showed a decrease at age 60 years. Testis volume and TT did not show significant difference among the four age groups; cFT began to decrease at age 50 years and Bio-T decreased faster at age 50 years. SHBG and LH increased faster at age 50 and 70 years, respectively. IIEF5 score decrease faster at age 60 years. AMS scores increased faster at age 70 years. With the increase in age, the symptoms of ED and SLOH became severer.

Conclusion: Different indices on reproductive health of men showed turning points at different ages. At first, androgenic sex hormones decreased faster, and then erectile dysfunction got severer, and the last overall male syndromes declined.     

China and global internet governance: toward an alternative analytical framework

Drawing on historical methods, this study assesses the conventional “cyber-sovereignty” framework, which has been used to capture and interpret China’s stance toward global Internet governance. This framework focuses on political control and tends to reduce China’s policies to the attempts by an authoritarian state to elevate governments and intergovernmental organizations to be the only legitimate governors of global cyberspace. As it traces the evolution of China’s relationship with the global Internet in the past three decades, the study demonstrates that China’s stance is more complex than the prevalent framework allows and that it is both built upon and different from the US-centric, market-oriented Internet governance scheme. This study recognizes the inadequacy of the conventional framework and invokes a theory of critical political economy of communication, thereby offering an alternative model to explicate the complex power dynamics behind China’s changing strategies. The alternative model advanced in this study is based on the understanding of China’s evolving approach as the product of multifaceted interactions among a group of power-holders that include both state agencies and business units on the transnational level.
