对2012年美国总统大选的政治传播学探讨——以奥巴马竞选团队的新媒体运用为例

2008年,奥巴马的竞选充分利用了互联网的优势,把美国政治引入Web 2.0时代。四年后的2012年,美国的传播环境在一些重要领域发生了变化。不仅互联网的影响力进一步加深,以推特为代表的社交媒体也已成为美国人生活中的重要组成部分。本文在总结这些变化的基础上观察了奥巴马竞选团队在2012年总统大选中对新媒体技术的运用,讨论和分析了相关变化对今后的美国总统大选以及政府日常施政带来的影响。     

论行政检查的概念:学理研究与法律规定

行政检查的概念在学理研究和实定法上以多种面相出现,厘清这一概念尤为必要.文章梳理了日本、韩国、英美、我国台湾地区有关行政检查的概念,重点探讨了我国学理研究和实定法上有关行政检查的概念,并总结了行政检查含义的演变趋势.排除行政调查中纯粹的资料搜集行为,行政检查等同于行政调查,是指行政主体对行政相对人是否遵守国家的法律、法规、规章的情况,作单方面强制了解的行政行为     

Correlation Coefficient Revisited

Elementary approaches to prove basic properties of the correlation coefficient are of pedagogical interest. Besides posing another proof, this article gives variations of the proofs already existing in the statistical literature     

Case–control genome-wide joint association study using semiparametric empirical model and approximate Bayes factor

We propose a semiparametric approach for the analysis of case–control genome-wide association study. Parametric components are used to model both the conditional distribution of the case status given the covariates and the distribution of genotype counts, whereas the distribution of the covariates are modelled nonparametrically. This yields a direct and joint modelling of the case status, covariates and genotype counts, and gives a better understanding of the disease mechanism and results in more reliable conclusions. Side information, such as the disease prevalence, can be conveniently incorporated into the model by an empirical likelihood approach and leads to more efficient estimates and a powerful test in the detection of disease-associated SNPs. Profiling is used to eliminate a nuisance nonparametric component, and the resulting profile empirical likelihood estimates are shown to be consistent and asymptotically normal. For the hypothesis test on disease association, we apply the approximate Bayes factor (ABF) which is computationally simple and most desirable in genome-wide association studies where hundreds of thousands to a million genetic markers are tested. We treat the approximate Bayes factor as a hybrid Bayes factor which replaces the full data by the maximum likelihood estimates of the parameters of interest in the full model and derive it under a general setting. The deviation from Hardy–Weinberg Equilibrium (HWE) is also taken into account and the ABF for HWE using cases is shown to provide evidence of association between a disease and a genetic marker. Simulation studies and an application are further provided to illustrate the utility of the proposed methodology.     

拿来之后——期待可能性本土化之思考

期待可能性理论有坚实的哲学和法理基础,在关注人性、体现刑法谦抑性和发挥刑罚功能等方面具有强大的理论吸引力,但是也存在对罪刑法定原则可能构成潜在危害,对法官素质具有较高要求,对完善的配套法律制度较为依赖等问题。因此,引进该理论应当慎重,应当在明确该理论在中国犯罪构成中的地位、在中国刑法和刑法理论中的功能,并设置相应的程序保障后再予以适用。     

An Analysis on What Role Population Factors Play for Water Resource Pressure in Beijing

How much water resource pressure is jointly determined by demand and water supply conditions? How much role and influence does the demographic factor play? What is the relationship between the demographic factor and the other driving factors? An in-depth study has a very important significance because the above issues directly related to the future policy formulation with population, economic and resources. Based upon analysis of water resource pressure changing trend in Beijing,the driving factors of the usage of water resources from 2001 to 2010 were analyzed using the LMDI decomposition method. Furthermore, the status and role of demographic factors (including population size,household size and so on) and other various driving factors were studied. The results are shown below: The water resource pressure is not only high, but also continually rising year by year; the greatest growth driving factor of the water usage is GDP per capita growth; the demographic factor (including population size,the amount of family and household size and so on) has some influences on the changes of water usage, but it is not the main factor. Improvement for the utilization of water resources in the productive sector and proper guidance for a rational consumption view are very important to alleviate the water pressure and improve the population carrying capacity.

青年领导干部要增强宪法意识纪念1982年宪法实施20周年

目前,青年领导干部中表现出来的宪法意识偏差主要表现为轻视宪法学习、缺乏宪法信仰;忽视宪法特性,降低宪法地位.相伴而生的主要违宪行为即是违背宪法精神、超限行使权力;违反宪法规定,侵犯公民权利.因此,必须要以有计划的培训考核;推动青年领导干部学习"三个代表"思想与宪法精神的一致性、学习宪法条款;强化人民民主与权利观念;以转变领导方式和工作方法去落实依法行政;发挥学习、遵守、使用宪法的表率作用.
