In 1831, the British Government decided to become directly involved in the provision of elementary education in Ireland, a country over which it then had jurisdiction. By European standards of the time this was a highly unusual step. A number of scholars have interrogated the factors that led to this outcome as well as the role played by various individuals. Daniel O’Connell’s activities, at this time, have been described as relatively limited, which appears incongruous given that he is considered the most powerful Irish politician of this era and was then at the height of his powers. It is the central contention of this article that O’Connell was, in fact, intimately involved in bringing about a national system of elementary education. Of more lasting significance is the manner in which he defined the role of the politician vis-à-vis the Church authorities in educational policy-making. In this regard he established a pattern that remained unchanged for over a century and indeed, it could be argued, largely persists to this day. 相似文献

《啊!拓荒者》是薇拉·凯瑟最有特色的一部代表作.凯瑟的宗教观影响了她对小说中人物的看法和命运安排;她对《圣经》中的某些诫律和典故的套用,丰富和充实了作品的内容;她对"叙述暴力"的适度运用,使作品产生了撼人心魄的效果.凯瑟捍卫传统的道德观,鄙视违反宗教教义的不忠与苟合.与此同时,她又对某些宗教教叉产生了怀疑,并希望对其进行改革. 相似文献

研究了多重周期饥饿对奥尼罗非鱼(Oreochromis niloticus×O.Areus.)肝胰脏及胃肠内蛋白酶活性的影响.分成4组:对照组、饥饿1 d投喂6 d(实验1组)、饥饿2 d投喂5 d(实验2组)和饥饿3 d投喂4 d(实验3组),实验持续56d.结果显示:循环饥饿处理和恢复投喂后,肝胰脏内胰蛋白酶的活力表现高度一致,实验1组均显著高于对照组和实验3组(P<0.05);胃肠内胰蛋白酶活力随循环饥饿时间的延长逐渐下降,恢复投喂后实验1组胃肠内胰蛋白酶活力显著高于其它三组(P<0.05);肝胰脏和胃肠内胃蛋白酶活力随循环饥饿时间延长均逐步下降,恢复投喂后肝胰脏及胃肠内胃蛋白酶活力从高至低依次为:实验1组、实验2组、实验3组和对照组. 相似文献

奥尼尔的影响几乎贯穿了整个中国现代戏剧发展的进程。洪深、曹禺和李龙云的部分创作实践体现了这种复杂的互动关系,同时也表明了奥尼尔对于中国现代戏剧创作的影响,更多的是一种启示,它为中国现代戏剧的进一步发展贡献了一块可供熔铸的基石。 相似文献

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

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
