Intergenerational conflict and public education expenditure when there is co-residence between the elderly and young

The main objective of this paper is to show that a family arrangement in which the elderly co-reside with the young determines that the elderly support the public education expenditure. Considering that this type of family arrangement is more common in Latin American countries than in the United States, our study is concentrated in Brazil. This study is based on a panel of 2054 Brazilian municipalities using data from the 1991 and 2000 censuses.     

Strategic interaction among public school districts: Evidence on spatial interdependence in school inputs

This paper provides evidence on strategic interaction among public school districts in Massachusetts. The open enrollment program in Massachusetts is unique in testing the strategic competition thesis because it allows students to attend public schools located outside their home district. For each student who transfers out, funds are deducted from the sending district's local aid distribution and added to the receiving district's local aid. Thus, school districts no longer have the assurance of a ready supply of students and funding, instead they have to compete with neighboring districts, and enact strategies that will help retain as well as attract more students. A spatial econometric framework is applied to disentangle the correlation due to strategic interaction from the one that is simply due to spatially correlated error shocks. The results show that public school districts respond positively to the expenditure decisions of neighboring districts, thereby acting strategically when setting their own spending levels.

柠檬酸溶胶凝胶法制备铈锆固溶体的物性和氧化还原特性研究

以柠檬酸作为胶凝剂,采用溶胶凝胶法制备了一系列CeXZr1-XO2复合氧化物,分别经600℃和900℃焙烧,应用XRD检测,发现均已形成铈锆固溶体。并应用BET、XRD和TPR对其表相、晶相结构和氧化还原性质进行了分析,发现随着固溶体中铈比例的增加,固溶体稳定性降低;其储氧量测定显示铈锆固溶体用作三效催化剂助剂的最佳比例为1：1。经900℃高温焙烧以后,固溶体晶粒增大不明显,表明本方法适合制备高比表面积和高储氧量的铈锆固溶体;TPR还原峰温度降低,推测可能在于柠檬酸络合物完全分解所致。     

两难的选择──劳伦斯北美时期作品的后殖民主义阅读

劳伦斯是最早去墨西哥和美国西部的英国作家,在殖民地期间他创作了多部传世之作,但有些作品带有较多的殖民主义话语。与土著人耳濡目染的生活使他改变了对印第安人的看法,并开始重新审视西方文化中的殖民主义倾向,但他无法彻底摆脱宗主国的影响。代表作《骑马出走的女人》以及《羽蛇》等充分地反映了他这个时期的思想转变过程。     

评尼采关于人的本质与自由的学说

本文在概述了尼采关于人的本质与自由的思想之后 ,指出 :尼采所理解的自由 ,是少数英雄人物的自由 ,这种自由是以不平等为前提的 ;尼采反对平等 ,有其深刻道理 ,而一般人理解的平等 ,不过是伪平等。本文还纠正了人们的一些误解 ,指出尼采并不是社会达尔文主义、虚无主义和反道德主义 ,尼采所反对的只是旧道德 ,并不反对一切道德 ,因为他提供了一种新的英雄道德。尼采还是后现代主义和弗洛伊德的先驱。
