氯与高锰酸钾联用灭活细菌的试验研究

以配置的水样为研究对象考察了氯与高锰酸钾单独使用及联用灭活细菌的效果。试验结果表明：投药总量相同情况下,二者联用消毒的效果与单独氯消毒的效果相当,有时甚至略好于单独氯消毒;用Berenbaum公式计算得出氯与高锰酸钾联用灭活细菌时浓度比为0.71,氯与高锰酸钾联用对细菌为协同灭活作用。     

转移支付制度的国际比较与借鉴

如何建立规范的财政转移支付制度,是当前进一步完善分税制财政体制的重大问题。借鉴发达国家财政转移支付制度的有益做法,结合我国实际,笔者认为,今后完善转移支付制度重点应放在转移支付目标的确定、补助方式的选择及制度的规范化等方面

A survey of functional principal component analysis

Advances in data collection and storage have tremendously increased the presence of functional data, whose graphical representations are curves, images or shapes. As a new area of statistics, functional data analysis extends existing methodologies and theories from the realms of functional analysis, generalized linear model, multivariate data analysis, nonparametric statistics, regression models and many others. From both methodological and practical viewpoints, this paper provides a review of functional principal component analysis, and its use in explanatory analysis, modeling and forecasting, and classification of functional data.     

收益重组与秩序再造:建国初期的农村减租运动——以无锡为中心

建国初期的土地改革是土地私有制向公有制转变的过渡阶段。在解放之初的苏南地区,由于地权形态和政治状况比较复杂,中国共产党采取了谨慎渐进的减租政策,对农村的土地收益权进行了调整,初步动员了农民,为之后的土地改革奠定了合法性基础。     

Bootstrap methods for stationary functional time series

Bootstrap methods for estimating the long-run covariance of stationary functional time series are considered. We introduce a versatile bootstrap method that relies on functional principal component analysis, where principal component scores can be bootstrapped by maximum entropy. Two other bootstrap methods resample error functions, after the dependence structure being modeled linearly by a sieve method or nonlinearly by a functional kernel regression. Through a series of Monte-Carlo simulation, we evaluate and compare the finite-sample performances of these three bootstrap methods for estimating the long-run covariance in a functional time series. Using the intraday particulate matter (\(\hbox {PM}_{10}\)) dataset in Graz, the proposed bootstrap methods provide a way of constructing the distribution of estimated long-run covariance for functional time series.     

论我国城乡职业教育资源的优化配置

城乡统筹,实现职业教育资源的优化配置,其重大意义在于:发挥了城市对乡村的辐射带动作用,找到了城乡结合、院校协作、资源共享的最佳契合点,也使多渠道转移农民就业变为现实。鉴于我国职业教育经费投入重城轻乡、专业设置重工轻农、院校布局重东部轻西部的实际,实现职教资源优化,应秉持城乡一体化、资源效能最优化和社会效益最大化的原则。具体举措为:统一领导,发挥政策的引领、规范作用;统一规划,构建我国东部支援西部、城市支援乡村的职教资源优化配置网络;创新思维,多渠道筹集财力资源;创造条件,鼓励双师型教师、优秀毕业生到贫困地区任教;精成援助,校际之间实现软硬件资源整合共享。     

Missing Elements in the Protection of Children: Three Cases from China

ABSTRACT.

The article analyzes 3 severe cases of child abuse that were widely discussed in the mass media in China in 2007 based on a framework used by the International Society for Prevention of Child Abuse and Neglect in its official publication World Perspectives on Child Abuse. The framework sets out the basic elements that must be included in systems of child protection: a) a responsible government or government-authorized organization; b) a set of institutional arrangements for reporting cases of child abuse, investigation, and intervening when necessary; and c) state guardianship or mechanisms to remove children from their parents’ care when necessary. By applying the framework to the 3 cases under analysis, the authors found that these basic elements are missing from the Chinese child protection system, and therefore, they recommend that a reform of the system to address these elements should be a priority for Chinese social policy. The article makes a number of recommendations for reform.     

Looking for best practice in caring for disabled children: a case of socialized foster care in China

This study focuses on the problems associated with caring for children with cerebral palsy (CWCP) in Chinese State Children's Welfare Institutions (SCWIs). It considers how to place these children with foster families and also provide them with the best rehabilitation services. In a pilot project, one SCWI trained foster parents as rehabilitators and provided services to CWCPs living with foster families in selected rural communities. The practice was very successful over the last decade, and more than 600 CWCPs in these communities are growing up happily. Hence, specialized foster care projects could be a solution for all SCWIs in China, where most of the institutionalized children are disabled.     

探索城市景观形象建设的新思路

改革开放30年来．我国经济社会发生了巨大变化,城市化步伐加快．城市面貌日新月异。21世纪是城市经济的世纪．高速的城市化发展进程．为我国的经济社会持续快速发展提供了基础平台．有效地提高了国民的物质和文化生活质量。另一方面．为适应快速发展的需要,提高城市建设的速度．许多城市简单地采用“模式化”建设方式．忽略了城市的自身特色、地域特点等．照搬照抄国内外其他城市的建筑、风格、特色等,造成了城市建设“千城一面、个性丧失、整体空间景观形象混乱”等问题和遗憾。
