西部民族地区人力资源开发的战略思考——以贵州省为个案

如果把贵州作为西部民族地区的一个缩影来看，在制约贵州经济发展的诸要素中，劳动力素质低下、人才普遍缺乏是其根本原因。要加快贵州人力资源的开发，必须大力发展教育事业，培养高素质人才；制定有利于人才合理流动的机制；加强和改善卫生保健服务；还要重视限制人口数量、提高质量、优化人口智能结构的政策，因地制宜地制定一个明确的人力资源开发计划。     

中国乡城流动人口社会网络复杂性特征分析

借助社会网络等非正式制度方式实现再社会化是乡城流动人口融入城市生活的主要途径之一。对流动人口社会网络的分析不仅可以揭示其网络结构特点,也将为进一步研究流动人口再社会化过程提供理论基础。采用深圳市流动人口专项调查中的整体网络数据,借助复杂性科学,尤其是复杂网络的研究方法,系统分析了乡城流动人口社会支持网络与讨论网络的复杂性特征。在乡城流动人口社会网络中广泛存在小世界现象和无标度特性等复杂网络特征。复杂性科学可以为分析诸如乡城流动人口这样的复杂系统提供有效方法,也是拓展复杂性科学,尤其是复杂网络应用领域的有益尝试。

二十世纪中国农业教育的分期研究

我国现代农业教育发端于19世纪末到20世纪初，经历刚刚过去的百年发展，已经初步形成了具有中国特色的农业教育体系。回顾20世纪的发展轨迹，有筚路蓝缕的艰辛，有曲折动荡的苦涩。也有辉煌成就的慰藉。本文以20世纪中国农业教育的思想变革和学制发展为主线，尝试将百年农业教育划分为四个历史发展时期，并研究分析了不同历史时期的发展状况和发展特征。

Short-Term Water Consumption Patterns in Ciudad Juárez, Mexico

Water utility planning efforts are becoming increasingly difficult throughout the world. Located in a semi-arid region, Ciudad Juárez, Mexico is a fast growing municipality that faces both physical infrastructure and water supply constraints. This paper examines monthly water consumption in Ciudad Juárez utilizing a linear transfer function procedure (LTF). Analysis is carried out for per customer usage and for the total number of municipal water system accounts. Models estimated for both series are subjected to a series of simulation benchmark tests. Findings suggest that water consumption in Ciudad Juárez reacts quickly to changes in economic and weather conditions. Out-of-sample simulation results are mixed. Per customer usage forecasts do not fare as well those for total customers relative to random walk benchmarks.Financial support for this research was provided by Southwest Center for Environmental Research Policy Grant W-04-03. Additional financial support was provided by El Paso Electric Company, Wells Fargo Bank of El Paso, and National Science Foundation Grant SES-0332001. Helpful comments and suggestions were provided by Cely Ronquillo, Brian Kelley, and Cesar Olivas. Econometric research assistance was provided by Marycruz De Leon and Irma Torres.     

臭氧在饮用水处理过程中的应用

地下水源污染日益严重。将臭氧-活性炭-纳滤膜应用于浅层地下水的净化中，该工艺能有效地去除地下水中的有机污染物，臭氧对地下水中CODMn,UV254、TOC等有机物综合指标去除率平均为13％、15％、17％，臭氧一活性炭联用后时CODMn和UV254的去除效率分别为64％、69．8％、64％，纳滤膜对CODMn和UV254、TOC的去除效率分别为58％、65％、65％。     

Euro area inflation persistence

This paper presents evidence on the lag between monetary policy actions and the response of inflation in the euro area as a whole as well as in some of its core countries, notably Germany, Italy and France. In line with previous findings for the US and the UK, results here show that it takes over a year before monetary policy actions have their maximum effect on inflation both in the euro area and in individual countries and that a lag of this length has existed in Europe at least since the collapse of the Bretton Woods system, despite the numerous changes in European monetary policy regime thereafter. Results based on alternative definitions of inflation persistence support these findings and indicate, if any, that transmission lags could be in fact much longer for individual countries and the euro area as a whole, although, at the country level, there is strong evidence over time of a drop in German inflation persistence and a sizeable shift in the mean of inflation – particularly in Italy and France. An examination based on results from this paper reveals that euro area inflation persistence could well be an intrinsic phenomenon rather than a ‘statistical fluke’ due to aggregation.This research was conducted during my visit at the European Central Bank Directorate Research, as part of the Research Visitor Programme. I would like to thank Anna Maria Agresti for providing individual country data from the macroeconomic database of the Monetary Transmission Network; Alistair Dieppe for providing data from the ECB area-wide model dataset; and Michele Manna for supplying me with the area-wide M3 data for the period 1970–1980. I thank Gabriel Fagan, Frank Smets, Ignazio Angeloni, Vítor Gaspar, Michael Ehrmann, Guenter Coenen, Oreste Tristani, Tommaso Monacelli, Stephanie Schmitt-Grohe and Gerhard Ruenstler for helpful discussions during my stay at the ECB. I would also like to thank seminar participants at the ECB for their input and I am very grateful to Jeffrey Fuhrer, Edward Nelson and Kenneth West, Bernd Fitzenberger and two anonymous referees for comments on an earlier draft.

The Race to Connect East Asia: An Unending Steeplechase

East Asia has become more integrated as a region over the past quarter century. In looking ahead, this article identifies five central obstacles to further regionalism. Three address the composition of any future East Asian region: the arenas in which cooperation is sought, the geographic scope of any future region, and the extent to which regional ties are formalized. The other two variables will influence the future regardless of how the first three are resolved: the structure and balance of domestic political forces, and leadership. The complex interactions of these five are then examined in the recent moves toward preferential trade pacts, increased regional monetary and financial cooperation, and security.
