Temporal Analysis of Human Development Indicators: Principal Component Approach

In this study, we used the weighted principal component method on the human development indicators to measure and analyzethe progress of human development in the world. The main principal component was employed to quantify the temporal changes of the human development of several selected countries by the proposed Z-test. The trends of the human development in the period of market transition in two large countries, China and Russia, were discussed in terms of the impact of public health as well as economic development. The association of the main principal component obtained from our study and the human development index reported by the United Nations Development Programme was estimated by the Spearmans rank correlation coefficient.     

中国城市的经济增长和资源环境——基于生产力的实证分析

考察节能减排约束下的中国城市经济增长绩效,利用2001—2010年间中国110个重点城市的气体、液体和固体环境的工业数据,逐步添加资源、环境污染产出和投入等变量,运用基于松弛的序列方向性距离函数和Luenberger生产力指数等方法测算城市效率、生产力指数和环境生产率,描述中国城市工业增长现状。结果显示: 城市平均效率值是0.705;生产力变动是0.091,其按照效率变动和技术变动分解后分别为0.009和0.082,表明技术进步是生产力的提高动力,能源和环境管理效率提升并未显露;能源消耗、污染排放、污染治理投资是影响生产力测算重要因素;中国城市减排工作的压力要远大于节能工作的压力。     

文化差异与民族地区学生低学业成就分析

加强民族地区教育是提高民族地区人口素质,实现民族地区跨越式发展的关键。民族地区的教育实际上是一个游离于内部文化和外部文化两套文化体系的存在。文化差异是导致民族地区学生低学业成就不可忽视的重要因素之一。结合贵州实际,从家庭和社区两个层面,分析文化差异对学生学业成就的影响,并提出一些解决办法。     

民族节日符号的现代转型及动力探析——以贵州苗族节日为例

节日符号是民族在长期历史实存中形成并在特定时日集中展现的相关文化元素的集合,显性地集聚表达了该民族的某些文化特性.本文通过时贵州苗族传统节日符号现代转型的考察,揭示出传统节日符号的现代转型是以三种具体路径来实现的.在此基础上,文章还探讨了传统民族节日符号在新的历史转折期转型的深层动因.文章认为,国家化和市场化双重力量的交织作用,是传统节日符号转型的基本动力所在.     

民用机场电磁环境保护的法律问题研究 ——基于《民用机场管理条例》的修订和实施

电磁环境保护是保障民用机场运行安全的重要制度,在中国具备良好的法律基础和执法机制.然而,随着无线电干扰活动的实践发展和民航领域航行新技术的应用,现行民用机场电磁环境保护制度需要进行相应的修订和完善.在立法层面,《民用机场管理条例》应当以列举的方式明确禁止在机场及附近区域放飞无人机和使用无线电信号干扰设备,将电磁环境保护对象由"民用航空无线电专用频率"扩大修订为"民用航空无线电相关频率".在执法层面,应当充分保障民航有关部门对联合执法机制的介入程度,由无线电管理部门贯彻实施《无线电管理条例》《民用机场管理条例》等法律法规对航空器等公共安全相关频率的严格保护,不将责令改正作为行政罚款的前置程序,对非法无线电干扰设备的全链条活动处以高额罚款,以最大限度地保护民用机场电磁环境安全.     

基于集成化物流中心的蔬菜供应链金融模式探析

近来,“菜贱伤农”“天价蔬菜”“毒蔬菜”等问题频繁出现在我们身边,却迟迟得不到“根治”。文章提出了以物流中心为核心的高度集成化的蔬菜供应链新模式,着重分析了蔬菜供应链新模式的“四流困境”及其金融环境支持条件,并从宏观和微观角度,为蔬菜供应链新模式的推动与实施,提出了相关的应对之策。     

Statistical Properties of Generalized Gini Coefficient with Application to Health Inequality Measurement

In this article, we report statistical properties of two classes of generalized Gini coefficients (G1 and G2). The theoretical results were assessed via Monte Carlo simulations. Further, we used G1 and G2 on life expectancy to measure health inequalities among the provinces of China and the states of the United States. For China, the results indicated that there was statistically significant health inequality by both G1 and G2. However, for the US, the results showed that there was significant health inequality by G1 but no statistical significance was found in health inequality by G2. Overall, from our study, China has higher health inequality than the United States.     

民初政治与黄远生的法治思想

黄远生善于撰写新闻通讯,被誉为“报界奇才”。《远生遗著》是其新闻通讯的结晶,它堪称民初政治斗争的实录。通过对其解读,可以使我们看出民初政治的轮廓和黄远生所持的法治思想。民初政治与黄远生的法治思想有融合和冲突的一面,从而导致其在不同阶段的不同立场。     

Box–Cox transformation for spatial linear models: a study on lattice data

In this article, we extended the classic Box–Cox transformation to spatial linear models. For a comparative study, the proposed models were applied to a real data set of Chinese population growth and economic development with three different structures: no spatial correction, conditional autoregressive and simultaneous autoregressive. Maximal likelihood method was used to estimate the Box–Cox parameter λ and other parameters in the models. The residuals of the models were analyzed through Moran’s I and Geary’s c.
