社会边缘群体对社会稳定的影响及对策--以哈尔滨建筑业农民工为例

社会稳定和社会边缘群体的生存状况紧密相连.建筑业农民工群体是中国社会边缘群体的重要组成部分,必须通过实证研究分析他们的生存状态及其与社会稳定之间的关系.通过抽样方法和问卷调查,从经济状况、社会分配、社会心理和社会控制等四个方面透视哈尔滨市建筑业农民工群体的生活状况,目前还不是影响社会稳定的因素.但从长期来看,若不注重研究并改善其境遇,则可能成为社会稳定的隐患.鉴于此,必须综合利用农民工社会保障制度、工会组织、技能培训、改善食宿和安全条件以及多样化的休闲途径,来保证这一群体的生活质量和合法权益,以维护社会稳定.

政治发展与公民参与——在新的社会阶层中发展党员的政治学思考

江泽民总书记在“七一”讲话中提出了扩大我们党的阶级基础和群众基础的问题。政党是现代社会中政治运行的重要手段 ,通过政党参与政治是公民参政的重要形式 ,它对政治体系的稳定作用主要体现在 :政党沟通了公民与政府之间的联系 ,为公民参政提供了制度化渠道 ;政党充当了公民与政府之间的“过滤层”,把公民参政限制在政治体系所能容纳的范围之内 ;有利于更好地发挥政党的政治社会化作用。在我国现阶段通过吸收新的社会阶层中的优秀分子加入党组织 ,发挥政党的参政功能 ,是扩大政治参与和保持政治稳定的最佳选择

La médiane simpliciale d'Oja: Existence,unicité et stabilité

Oja (1983) examined various ways of measuring location, scatter, skewness, and kurtosis for multivariate distributions. Among other measures of location, he introduced a generalised median known in this paper under the name of the Oja median. In our study of the existence of that median, we show that Oja's definition can only be applied to distributions having a mean. In dimension d θ 2, we establish that the usual method of extension breaks down, which raises the question of the validity of the concept as a notion of median. Two fundamental theoretical properties of that median are also considered: uniqueness and consistency.     

成语的范围问题

单一的标准不能把成语同熟语的其他类型区别开来 ,应该用综合的标准确定成语的范围。本文提出了三项标准 :音节的标准 ,语体的标准和历史的标准

Total Economic Consequences of an Influenza Outbreak in the United States

Pandemic influenza represents a serious threat not only to the population of the United States, but also to its economy. In this study, we analyze the total economic consequences of potential influenza outbreaks in the United States for four cases based on the distinctions between disease severity and the presence/absence of vaccinations. The analysis is based on data and parameters on influenza obtained from the Centers for Disease Control and the general literature. A state‐of‐the‐art economic impact modeling approach, computable general equilibrium, is applied to analyze a wide range of potential impacts stemming from the outbreaks. This study examines the economic impacts from changes in medical expenditures and workforce participation, and also takes into consideration different types of avoidance behavior and resilience actions not previously fully studied. Our results indicate that, in the absence of avoidance and resilience effects, a pandemic influenza outbreak could result in a loss in U.S. GDP of $25.4 billion, but that vaccination could reduce the losses to $19.9 billion. When behavioral and resilience factors are taken into account, a pandemic influenza outbreak could result in GDP losses of $45.3 billion without vaccination and $34.4 billion with vaccination. These results indicate the importance of including a broader set of causal factors to achieve more accurate estimates of the total economic impacts of not just pandemic influenza but biothreats in general. The results also highlight a number of actionable items that government policymakers and public health officials can use to help reduce potential economic losses from the outbreaks.     

井壁稳定性分析在靖边气田水平井钻井设计中的应用简

井壁稳定性问题（即井壁坍塌破裂）会引起系列严重的井下卡钻井漏等事故。靖边气田在钻井过程中,钻遇的地层当中存在多煤层,井壁稳定性问题十分突出,在该地区水平井钻井设计当中进行井壁稳定性分析有着重要的意义。分析了井壁围岩应力分布规律并建立地层坍塌（破裂）压力计算模式,根据库仑-摩尔强度准则和最大拉应力破裂准则,计算井壁坍塌（破裂）压力与钻井液安全密度窗口。通过实验研究分析煤层坍塌压力和破裂压力随井斜角、方位角变化规律,提出合理的方位角优选方案,指导水平井钻井方案设计。
