当前我国社会保障存在的问题及其改革措施

自《中华人民共和国劳动保险条例》颁布始 ,中国社会保障制度已走过 50年发展历程 ,社会保障制度从雏形到逐步成熟和规范。当前我国社会保障实践在成绩中隐含着许多矛盾和问题 ,因此 ,应尽快建立起独立于企业事业单位之外、资金来源多元化、保障制度规范化、管理服务社会化的社会保障体系已是迫在眉睫     

思想政治教育网络传播受众动机特征及对策分析

受众是思想政治教育网络传播的重要构成要素,研究受众接受动机成为提高思想政治教育网络传播效果的关键。思想政治教育的受众具有求知、交流、宣泄、求实和自我实现的动机,尊重受众的知情权,增强互动设置,提供适当的宣泄平台,加强网站的服务性功能,提高可供受众创造力发挥的平台是基本的对策。     

影响低年级大学生心理状态因素的分析

本文通过对低年级大学生心理状态的调查分析,认为大学生自身的内在心理素质和周围环境的外在条件相互作用不均衡将导致心理问题的产生,并强调"适应期"教育,促进低年级学生身心健康.

论"以德治校"在学校教育中的作用及途径

以德治校的内涵应从微观的德育教学和宏观的育人方略两个层面进行阐述.以德治校不是"以红代专"、"以德代法".施行以德治校有利于党的教育方针的全面贯彻、素质教育策略的有效推进、以德治国战略思想的有力实施.以德治校的途径和措施应在办学方针、校园文化、德育教学、德育研究、队伍建设诸方面全方位、多渠道、深层次地得以体现.     

抗战时期西部的航空运输业建设

抗战爆发后,为打破日军封锁和开展大后方正常对外贸易,国民政府采取了一系列措施以重庆为中心发展西部航空运输业.西部航空运输业在发展中呈现出航线变动频繁、航空运输建设服从军事需要为主等特点.西部航空运输业经过三个阶段的发展,在一定程度上支持了抗战,并推动了整个中国民航运输业的发展.但由于航空人才缺乏、航空制造技术落后等原因,西部航空运输业的发展又难尽人意.     

Covariates and Random Effects in a Gamma Process Model with Application to Degradation and Failure

The gamma process is a natural model for degradation processes in which deterioration is supposed to take place gradually over time in a sequence of tiny increments. When units or individuals are observed over time it is often apparent that they degrade at different rates, even though no differences in treatment or environment are present. Thus, in applying gamma-process models to such data, it is necessary to allow for such unexplained differences. In the present paper this is accomplished by constructing a tractable gamma-process model incorporating a random effect. The model is fitted to some data on crack growth and corresponding goodness-of-fit tests are carried out. Prediction calculations for failure times defined in terms of degradation level passages are developed and illustrated.     

Influence of Safety Measures on the Risks of Transporting Dangerous Goods Through Road Tunnels

Quantitative risk assessment (QRA) models are used to estimate the risks of transporting dangerous goods and to assess the merits of introducing alternative risk reduction measures for different transportation scenarios and assumptions. A comprehensive QRA model recently was developed in Europe for application to road tunnels. This model can assess the merits of a limited number of "native safety measures." In this article, we introduce a procedure for extending its scope to include the treatment of a number of important "nonnative safety measures" of interest to tunnel operators and decisionmakers. Nonnative safety measures were not included in the original model specification. The suggested procedure makes use of expert judgment and Monte Carlo simulation methods to model uncertainty in the revised risk estimates. The results of a case study application are presented that involve the risks of transporting a given volume of flammable liquid through a 10-km road tunnel.     

关于增加农民收入的几点思考

通过对1997年至2000年我国连续4年农民收入下降原因的深入分析,提出增加农民收入的一些措施,认为增加农民收入需要大力推进农业结构的战略性调整,强化实施"科教兴农"发展战略,切实减轻农民负担,合理转移农村剩余劳动力,着力实现农业信息化以及加大对农业的支持、保护力度。
