独立学院大学生社团建设的思考

大学生社团作为校园文化建设的重要力量之一，应该以人为本，在注重培养个人能力的同时规范中求开放。加强校际间合作将是其发展的必由之路。     

Assessment of the Effectiveness of Radon Screening Programs in Reducing Lung Cancer Mortality

The present study was aimed at assessing the health consequences of the presence of radon in Quebec homes and the possible impact of various screening programs on lung cancer mortality. Lung cancer risk due to this radioactive gas was estimated according to the cancer risk model developed by the Sixth Committee on Biological Effects of Ionizing Radiations. Objective data on residential radon exposure, population mobility, and tobacco use in the study population were integrated into a Monte‐Carlo‐type model. Participation rates to radon screening programs were estimated from published data. According to the model used, approximately 10% of deaths due to lung cancer are attributable to residential radon exposure on a yearly basis in Quebec. In the long term, the promotion of a universal screening program would prevent less than one death/year on a province‐wide scale (0.8 case; IC 99%: –3.6 to 5.2 cases/year), for an overall reduction of 0.19% in radon‐related mortality. Reductions in mortality due to radon by (1) the implementation of a targeted screening program in the region with the highest concentrations, (2) the promotion of screening on a local basis with financial support, or (3) the realization of systematic investigations in primary and secondary schools would increase to 1%, 14%, and 16.4%, respectively, in the each of the populations targeted by these scenarios. Other than the battle against tobacco use, radon screening in public buildings thus currently appears as the most promising screening policy for reducing radon‐related lung cancer.     

基于Logistic模型产业集群演化稳定性研究

依据产业集群的内在关系,产业集群有非正式集群、有组织的集群、创新型集群三个层次或形态,针对不同演化形态我们分别建立了Logistic模型,并对稳定平衡态下企业共生经济效益进行了分析和对比,研究了它们共生的条件和原因。另外产业集群演化除了能够产生稳定平衡的、周期的动态行为外,还可能产生混沌的现象,单一的线性因果关系不能解释其演化规律;同时产业集群演化所具备的初值依赖性也促使演化混沌的可能产生;在集群演化混沌状态下,集群的演化发展方向、模式由集群内部企业间共生性和合作稳定性以及外部环境的影响共同决定。就我国产业集群的发展而言,要有条件有选择地引导产业集群的形成和发展,培育和加强集群内部的共生机制,应本着区域产业集群与区域经济协同发展的原则,选择适应性的产业集群发展战略。     

执政动机·执政程序·执政效果——解析执政行为的动态全过程

十七大报告指出,"全面推进党的建设新的伟大工程"要以"党的执政能力建设和先进性建设作为主线".而提高党的执政能力,关键是不断获得执政的合法性.执政能力建设是执政动机、执政程序、执政效果的有机统一.     

必须牢固确立"五位一体"的社会主义法治建设原则

社会主义法治建设必须结合当前我国社会主义经济发展的新情况,新问题,牢固确立"五住一体"的社会主义法治经济建设原则,即"马克思主义的指导地位、人民群众的主体地位、宪法和法律的权威地位、国家建设大局的中心地位、党的领导的核心地位".     

色散特性对毫米波频率步进雷达影响的研究

对影响毫米波频率步进雷达分辨率的主要因素进行了分析。除目标速度以外,为毫米波频率步进雷达提供频率信号的频率源的色散特性也会对雷达分辨率造成恶化影响。微波频段上的色散特性会被搬移到毫米波频段,导致毫米波发射信号和本振信号的初始相位差不为常数,对雷达系统尤其是距离分辨率造成严重影响。仿真结果与实验结果一致。为了抵消色散特性对雷达分辨率的恶化影响,可以通过对色散特性的补偿来实现。色散特性补偿的方法被应用到实现W波段频率步进频率源的设计中,满足了0.45m距离分辨率的要求。     

高校学生抑郁症高发率的社会影响因素

社会影响因素是高校学生抑郁症高发率的重要诱因之一,这种影响从人格发展的社会文化生态机制和社会对人格的个人行动建构模型与意动走向两个方面得以体现,应沿着相应方向对高校学生抑郁症高发率的问题采取相应对策.     

Inference for general parametric functions in box‐Cox‐type transformation models

The authors propose a simple but general method of inference for a parametric function of the Box‐Cox‐type transformation model. Their approach is built upon the classical normal theory but takes parameter estimation into account. It quickly leads to test statistics and confidence intervals for a linear combination of scaled or unsealed regression coefficients, as well as for the survivor function and marginal effects on the median or other quantité functions of an original response. The authors show through simulations that the finite‐sample performance of their method is often superior to the delta method, and that their approach is robust to mild departures from normality of error distributions. They illustrate their approach with a numerical example.     

《哈克》在中国之重译与流传

马克·吐温是中国译介作品最多的芙国小说家，他的经典代表作《哈克贝利·费恩历险记》在我国流传的重译本很多。众多的重译证明了这部文学名著的显赫地位和马克·吐温在中国的受欢迎程度。接受芙学理论从读者和译本两个角度分析了名著如《哈克》流传众多重译本的必然原因。     

论高校基本建设管理
