大学推动文化传承创新的当代境遇、原则与可行路径

面临着社会转型期特有的文化生态,我国大学推动文化传承创新的作用与意义在当代语境下变得日益重要。大学文化一经形成,将成为实现大学使命与目标的精神力量,成为社会影响力的一种源泉。推动大学文化传承创新,首先需要在大学文化创新中践行"育人为本"的核心理念;其次,使大学文化对内要有凝聚力和崇高的价值取向,对外具有感召力和精神魅力;第三,关注制度创新和文化创新的契合。     

论民族区域自治地区加强和创新宗教事务管理的法治路径

民族区域自治地区社会管理创新是一项比较复杂的系统工程,而包含在其中的宗教事务管理,更是一项十分复杂的系统工程,是社会管理创新的重点和难点。民族区域自治地区加强和创新宗教事务管理的法治建设,应当进一步健全国家法律与地方法规相互衔接配套的宗教事务管理法治体系,坚持进一步健全宗教事务管理领域的法律法规,坚持依法从严追究宗教活动中违法犯罪行为的刑事、民事或行政法律责任,坚持依法遏制国外宗教极端势力对我国的威胁,依法抵御境外敌对势力利用宗教进行的渗透和分裂破坏活动。     

Evaluation of environmental impacts of traction motor production and disposal

By the application of life cycle assessment（LCA） methodology, this paper estimates the environmental impacts of production and disposal of traction motors used in electric vehicles in China. The results show that the total energy use, the criteria emissions and the greenhouse gases（GHG） emissions of a traction motor production and disposal are about 2,899,MJ, 4.5,kg and 259.5,kg per motor, respectively. Among the regulated emissions, the SOxemission ranks first by total mass, followed by CO, PM10, NOx, PM2.5, and volatile organic compound（VOC）. The motor material production stage accounts for most of the energy consumption and emissions, followed by the assembly stage and the end-of-life disposal stage. In this study, the environmental performance analysis is extended to the comparison between the use of secondary material and primary material for the material production stage. It is found that using 100% secondary material results in a 52.9% reduction in energy consumption, a 49.8% reduction in regulated emissions, and a 49.3% reduction in GHG emissions compared with the use of 100% primary material.     

国家开放大学框架下诊所式教学模式的探索与反思

教学模式改革是人才培养模式改革的核心内容之一,也是国家开放大学建设的重要任务。法学专业作为国家开放大学的主要专业,其教学模式的探索具有重要意义。本文以大连电大法学专业"律师实务"课程为例,从教学大纲、教学模式、评价反思等方面进行探讨,经过分析得出:"诊所式"教学模式适合国家开放大学框架下法学专业学习者的需求,将成为未来远程高等法学教育的主要教学模式之一。

从模因论看文字体系的“二次约定”

“二次约定”是描述文字体系创建模式的一种崭新的语言符号观,并且这种对上一级符号的模仿和重建已成为文字体系形成过程中的主要构建机制。“二次约定”事实上就是符号与符号之间的“模仿’’和“复制”．不仅在文字体系内部,而且在文字体系之间也存在对已有符号的仿制和传播,这与模因论的基本观点是一致的。用模因论的属性分析文字体系的“二次约定”,有利于我们重视模因在文字符号及其构成体系中的影响和作用。

Evaluation of Test Statistics for Robust Structural Equation Modeling With Nonnormal Missing Data

A 2-stage robust procedure as well as an R package, rsem, were recently developed for structural equation modeling with nonnormal missing data by Yuan and Zhang (2012). Several test statistics that have been used for complete data analysis are employed to evaluate model fit in the 2-stage robust method. However, properties of these statistics under robust procedures for incomplete nonnormal data analysis have never been studied. This study aims to systematically evaluate and compare 5 test statistics, including a test statistic derived from normal-distribution-based maximum likelihood, a rescaled chi-square statistic, an adjusted chi-square statistic, a corrected residual-based asymptotical distribution-free chi-square statistic, and a residual-based F statistic. These statistics are evaluated under a linear growth curve model by varying 8 factors: population distribution, missing data mechanism, missing data rate, sample size, number of measurement occasions, covariance between the latent intercept and slope, variance of measurement errors, and downweighting rate of the 2-stage robust method. The performance of the test statistics varies and the one derived from the 2-stage normal-distribution-based maximum likelihood performs much worse than the other four. Application of the 2-stage robust method and of the test statistics is illustrated through growth curve analysis of mathematical ability development, using data on the Peabody Individual Achievement Test mathematics assessment from the National Longitudinal Survey of Youth 1997 Cohort.
