Equity and ‘No Fee’ Schools in South Africa: Challenges and Prospects

Despite almost 20 years of democratic governance in South Africa, there is growing evidence that equitable access to quality education remains elusive for the majority of its children. In 2007, the Department of Education declared 40 per cent of schools in the country to be ‘no fee’ schools and, by 2011, 60 per cent of all schools had been designated as such. This article examines the introduction and the effects to date of the no fee schools policy, and assesses the progress of South Africa's undoubtedly pro‐poor education policies towards promoting equality in education and, above all, achieving equity of access to resource allocation. It discusses the main challenges and issues relating to the implementation of the no fee policy at provincial and school levels while also considering the efficacy of existing equitable funding instruments, and concludes with suggestions for how more effective and equitable access to quality education can be realized.     

节目试看对网络视频运营商市场策略影响研究

随着网络视频运营商收费节目试看的兴起，而节目试看对网络视频运营商诸如市场规模，利润等市场策略的影响所知甚少。本文在考虑网络用户情绪效用情况下，通过构建高质量视频运营商首播节目与后来跟进的低质量视频运营商播出该节目的博弈模型，研究高质量视频运营商首播节目之前提供节目试看对两个运营商收费模式下的节目最优收费价格和免费模式下的最优嵌入广告量以及视频节目提供模式选择的影响。研究表明，高质量视频运营商在节目首播之前提供节目充分试看能够实现节目最优收费价格最高，利润最大，因此节目充分试看是其最优策略；并且低质量运营商在其单位广告收益与用户单位广告"成本"满足一定条件下，高质量运营商提供的节目的充分试看能够减少低质量运营商总利润，因此避免低质量视频运营商搭乘节目试看的顺风车；高质量视频运营商提供节目充分试看情况下，高质量视频运营商只采取收费模式为其最优市场策略，低质量视频运营商采取免费模式为其最优市场策略。本文的研究成果对网络视频运营商日常运营有一定的管理学启示与应用价值。

一个人的绞刑架——从苔丝看哈代的悲剧观

《德伯家的苔丝》是英国著名小说家托马斯.哈代的悲剧代表作。透过作品品读作者哈代的悲剧观,这种悲剧观不是让人痛让人哭,而是让人以一种淡淡的忧伤感受悲观,以局外人的淡定感受一种注定如此、必然这样的悲剧生成。哈代通过笔下的人物让读者看到他对待悲剧的态度,直接面对并坦然接受这种结局。     

Machine Learning Vasicek Model Calibration with Gaussian Processes

In this article, we calibrate the Vasicek interest rate model under the risk neutral measure by learning the model parameters using Gaussian processes for machine learning regression. The calibration is done by maximizing the likelihood of zero coupon bond log prices, using mean and covariance functions computed analytically, as well as likelihood derivatives with respect to the parameters. The maximization method used is the conjugate gradients. The only prices needed for calibration are zero coupon bond prices and the parameters are directly obtained in the arbitrage free risk neutral measure.     

基于分层教学理论的高职高专公共英语教改探索

针对高职高专院校学生生源的层次差异,英语教学可采用分层教学,即根据学生个体差异,将学生分成不同水平的班组,制订不同的计划、目标和方法进行教学。分层教学能够使更多的学生在各自基础上得到最为有效、合理的发展,使各类学生的潜能都能得到最大程度的开发。分层教学实施过程中,要注意制订科学合理的分层方案,进行科学有效的管理,注重教师教育科研水平的提升。     

An International Comparative Study on Women's Pension Rights and Their Economic Risks

This article examined the theoretical meanings of pension rights and analyzed their effects on women's economic risks in developed countries. First, based on the status of a citizen, worker, parent, and spouse, this study investigated how pension benefits are guaranteed as a citizen regardless of work history, the degree to which women's disadvantageous situations in the labor market and unpaid work are compensated by public pension as workers and parents, and how marital status is treated in the different pension systems. Second, analysis of the effect of pension rights showed that individual rights is a significant factor to prevent economic risks of elderly women. Derived rights did not seem to secure the economic welfare of elderly women, at least in a comparative context. This finding suggested that developing individual rights, rather than derived rights, is the way to guarantee long‐term elderly women's economic welfare.     

人性与自由情感——兼论奥斯卡影像美学

人类存在着两类不同性质的情感：自由情感和必然情感。所谓自由情感指的是刺激源和这种情感对象之间没有任何直接的利害关系条件下所产生的情感。美的本质就在于自由情感。奥斯卡艺术堪称电影艺术中的经典。奥斯卡奖近百年的评奖历史证明人性是社会大众和奥斯卡奖评委共同的最好的审美趣味激发源。其中爱情、亲情、友情是奥斯卡影像中最浓墨重彩的人性主题，是自由情感的主要源泉，也是奥斯卡影像美学的核心。
