论计划生育村民自治

建立健全“依法管理、村(居)民自治、优质服务、政策推动、综合治理”的长效工作机制,是《中共中央国务院关于全面加强人口和计划生育工作统筹解决人口问题的决定》(2006)对我国未来计划生育管理提出的基本要求,也是全国部分地区在人口和计划生育综合改革实践中探索出的一条基本经验。然而,对长效工作机制中的“村民自治”,人们在认识上还存在一些误区,从而导致了工作实践中的一些偏差。本文拟就计划生育村民自治中的几个基本问题谈点意见。1计划生育村民自治的概念村民自治是我国广大人民群众直接行使民主权利的一项基本社会政治制度。“计…     

家庭托育点管理实践及启示：政策工具的视角

家庭托育点的规范化对婴幼儿健康成长至关重要。通过文献收集和访谈获得既往管理举措和当前试点政策,运用政策工具进行分析和总结,探究管理家庭托育点的背景、对象和措施。结果表明：家庭托育点因经济优势而被纳入管理,现有征求意见稿管理对象偏向小规模邻托,但试点和市场偏向较大收托规模;消防审查依托既有消防验收,师资准入要求偏低,质量监管依靠政府。管理建议：应根据收托规模区分小型和大型家庭托育点开展试点;完善三方协同的管理架构,设定专门空间环境要求,提高师资准入要求,建立综合质量监管。     

论左翼文学发展中的报刊策略

兴起于1928年前后的左翼文学迅速成为20世纪30年代最有影响力的文学,这一文坛主流地位的确立与其发展中的报刊策略是分不开的。初期左翼文学借助庞大的期刊阵营迅速获取了在文坛上的流行性;左联刊物多样化的生存策略进一步扩大了左翼文学在文化围剿下的影响力,并拓展了其发展空间;左翼作家们对报纸副刊的广泛争夺成为后期左翼文学发展的主要特征。左翼文学正是通过巧妙利用报刊迅速完成了其兴起、发展、繁荣的过程。     

How Latinos Are Transforming the United States: Research, Theory, and Policy

The United States is entering a new era, a period marked by some important demographic changes in the composition of the population, most especially significant increases in the Latino and Latino immigrant segments of society. These population shifts require corresponding interpersonal, organizational, and structural changes. The present issue bridges research and theory across disciplines and includes studies incorporating a variety of methodologies to examine these important areas. These articles begin to fill some of the voids where a systematic and robust corpus of knowledge is lacking. The contributions address topics ranging from issues of identity and interpersonal relations to pressing matters of educational significance to general approaches to navigating the cultural transitions that mark fluid transnational adaptations. Finally, each contribution delineates the policy implications resulting from the processes and literatures that are examined.     

Human Capital,Trade Openness and Growth in Argentina in the 20th Century

We estimate a production function that accounts for the economic performance of the country in the 20th century. We elaborate long term time series whereas most of the recent empirical studies on growth are based on cross section analysis. This approach allows us to follow the various regime changes that can be identified in the rich economic history of Argentina. To evaluate Total Factor Productivity (TFP) we initially test the classical Solow Model. We estimate the speed of convergence of TFP and obtain a non convergence result. This speed of convergence has declined since the 1930s, and we find a phenomenon of divergence in the period 1970–90. We then analyse the impact on production of additional variables recently highlighted in the endogenous growth literature such as the process of catch up of foreign technical progress, human capital and trade openness. Chow tests for this extended production function give us a strong probability of changes in the growth regimes. The estimation, that takes into consideration the break points identified, shows that the impact of trade openness and foreign technology is not stable throughout the century. In what concerns the impact of education on economic growth, we find a strong effect of primary education on growth, and a weaker effect of secondary-university education.     

工业经济效益指标体系的再思考

为了适应社会主义市场经济的发展,国家统计局会同财政部、国家经贸委等有关部门对原有我国工业经济效益指标体系进行了修改,制订了一套新的工业经济效益综合评价考核指标体系,包括７项指标：总资产贡献率、资本保值增值率、资产负债率、流动资产周转率、成本费用利润率...     

Vector random fields with compactly supported covariance matrix functions

The objective of this paper is to construct covariance matrix functions whose entries are compactly supported, and to use them as building blocks to formulate other covariance matrix functions for second-order vector stochastic processes or random fields. In terms of the scale mixture of compactly supported covariance matrix functions, we derive a class of second-order vector stochastic processes on the real line whose direct and cross covariance functions are of Pólya type. Then some second-order vector random fields in R^d${\mathbb{R}}^d$ whose direct and cross covariance functions are compactly supported are constructed by using a convolution approach and a mixture approach.     

Lower posterior death probabilities from a quick medical response in road traffic accidents

Introduction: We use data from Spain on roads and motorways traffic accidents in May 2004 to quantify the statistical association between quick medical response time and mortality rate. Method: Probit and logit parameters are estimated by a Bayesian method in which samples from the posterior densities are obtained through an MCMC simulation scheme. We provide posterior credible intervals and posterior partial effects of a quick medical response at several time levels over which we express our prior beliefs. Results: A reduction of 5 min, from a 25-min response-time level, is associated with lower posterior probabilities of death in roads and motorways accidents of 24% and 30%, respectively.
