The role of educational quality and quantity in the process of economic development     

Amparo Castelló-Climent  Ana Hidalgo-Cabrillana 《Economics of Education Review》2012

We develop a theory of human capital investment to study the effects of school quality on student choices of education, and to understand its effect on economic growth. In a dynamic general equilibrium closed economy, primary education is mandatory but there is an opportunity to continue to secondary education and beyond. High-quality education increases the returns to schooling, and hence the incentives to accumulate human capital. This is caused by two different channels: higher quality makes education accessible to more people (extensive margin), and once individuals decide to participate in higher education, higher-quality increases the investment made per individual (intensive margin). Furthermore, educational quality determines human capital composition and growth. Cross-country data evidence shows that the proposed channels are quantitatively important and that the effect of the quality and quantity of education on growth depends on the stage of development.  相似文献   

The influence of price on school enrollment under Uganda's policy of free primary education     

Jane Arnold Lincove 《Economics of Education Review》2012

This study uses household survey data to estimate determinants of schooling in Uganda, with a model that includes the price of school. Uganda's universal education policy offered free tuition, fees, and supplies to up to four children per family, including two daughters. The empirical method includes an estimation of a child-specific price of schooling. Despite widespread subsidies, the cost of primary school remained an obstacle under this policy, but the effects of price were similar for boys and girls. Regressions by wealth quintile estimate nonlinear effects of wealth and price, suggesting that there are opportunities to expand education through targeted cash transfer and subsidy policies.  相似文献   

Inequality of opportunity for educational achievement in Latin America: Evidence from PISA 2006–2009     

Luis Fernando Gamboa  Fábio D. Waltenberg 《Economics of Education Review》2012

We evaluate how far away six Latin American countries stand from a normative goal of equality of opportunity for educational achievement in PISA 2006–2009. We work with alternative characterizations of types: gender, school type (public or private), parental education, and their combinations. Following Checchi–Peragine's (2010) non-parametric method, we find that inequality of opportunity for educational achievement in Latin America ranges from less than 1% to up to 25%, depending on the year, the country, the subject and the specification of circumstances. These magnitudes are substantial with respect to what is found in comparator countries. Parental education and school type prove to be important sources of inequality of opportunity, contrary to gender. By means of sensitivity analyses, while most results show small to moderate variation in terms of magnitudes, in ordinal terms (rankings) they remain quite stable. Brazil stands out as the most opportunity-unequal country of the sample.  相似文献   

论尤金·奥尼尔超前的生态意识——以《毛猿》的生态马克思主义解读为例     

周丽萍 《佳木斯教育学院学报》2012,(3):90-91

《毛猿》是奥尼尔早期的代表作之一。在这部作品中,奥尼尔运用戏剧创作手法刻画了遭到破坏的自然以及被剥削的工人阶级,展示了资本主义社会中人与自然,人与人之间的纯粹利益关系,表明整个人类已陷入生态危机的困境。而奥尼尔在剧中所表现出的对这一危机的思考:回归自然,建立公正公平的社会与生态马克思主义学者所提出的解决生态危机的观点不谋而合,表现了奥尼尔超前的生态意识。  相似文献

高效液相色谱法同时测定部分化妆品中的酸性橙7和碱性嫩黄O     

林森煜  黄金凤  白樱  黄荣荣 《顺德职业技术学院学报》2012,10(3):8-10

建立了化妆品中酸性橙7和碱性嫩黄O的高效液相色谱法。方法以甲醇为萃取溶剂,过0.45μm滤膜过滤后,以0.02 mol/L乙酸铵和甲醇经反相色谱柱梯度洗脱后,采用二极管阵列检测器检测,并用外标法定量计算。在5.0~20.0 mg/kg的添加水平,回收率在83.9%~94.0%之间,变异系数在4.4%~7.2%之间。  相似文献   

尖晶石型复合氧化物MAl_2O_4（M=Sr,Ba）的制备、表征及可见光催化性能研究     

林艺凤  朱启荣  何燕强  许江钦  张玲静  黄绍茂  陈蓉  牛玉 《三明高等专科学校学报》2012,(2):73-75

用柠檬酸络合法制备了尖晶石型复合氧化物SrAl2O4、BaAl2O4,用XRD、TEM等手段对催化剂结构和性能进行了表征,并考察了其在可见光下降解刚果红的催化性能。结果表明,在可见光条件下,60 min内BaAl2O4使刚果红降解率达80%以上,SrAl2O4降解率大约为70%。SrAl2O4的催化活性低于BaAl2O4可能是由于电子层结构的不同造成的。  相似文献   

奥康纳分析教育哲学思想研究     

朱镜人  张珍珍  韦立君 《合肥师范学院学报》2012,30(4):47-51

丹尼尔·约翰·奥康纳批判了传统哲学,认为传统哲学存在四点不足,这为其分析教育哲学思想奠定了理论基础;他用分析哲学的方法论述了语言分析的重要性,并对诸如教育、教育理论等重要概念作了深入的语言分析.奥康纳的理论在教育哲学界引起了不小的反响,同时也引起不少争议,其对传统哲学的批判有其一定的道理,对教育哲学的研究具有启发性.  相似文献   

氧空位对SrBi4Ti4015铁电陶瓷电性能的影响     

王晓军  雒卫廷 《雁北师范学院学报》2012,(6):20-22,25

用高温固相烧结法制备了SrBi4Ti4O15（SBTi）铁电陶瓷,用双氧水浸泡72h进行氧处理的样品与未经过氧处理的样品进行对比研究。样品的介电损耗谱表明：氧处理使SBTi在20℃～300℃温度范围内的介质损耗明显降低,这主要是由于氧处理使样品中氧空位浓度降低引起的。在温度高于300℃时,经过氧处理的样品的介质损耗迅速增大,这是因为氧处理使空穴载流子浓度增大。通过对材料的直流电导与温度关系的Arrhenius拟合,分析了SBTi的导电机理。结果表明,氧处理并未明显改变样品在300℃。650℃温度区域的栽流子激活能,却使其在20℃一300℃范围内的激活能从0．52eV变化到0．71eV。  相似文献
