专业实习教学辅助系统的开发与实践

学生实习是大学实践环节的重要内容,但在实际的实习中存在一些问题使实习无法达到应有的效果。随着计算机技术的普及,多媒体教育已在各级教育中起到了非常重要的作用。我校应用化学专业开发了专业实习辅助系统,该系统根据电厂真实情况并结合多媒体技术多方面的优点,介绍了电厂的锅炉、汽轮机、发电机、除尘、脱硫、化学水处理等原理及工艺流程。该软件在专业实习教学应用中反响良好。

福利危机与改革路径——20世纪90年代以来的香港社会救助

作为全球最活跃的经济体之一,香港一直坚持低税制、低福利、高发展的路线,并根据自身情况建立了一套具有香港特色的社会救助制度。但是,20世纪90年代后,经济、社会等领域发生的重大变化导致这一制度面临诸多问题。为此,香港政府进行了一系列改革,改革汲取了当代全球先进福利理念及经验,在许多方面突破了单纯强调收入援助的传统救助模式,而转向一种新的具有社会投资倾向的积极救助模式。

Stochastic efficiency analysis with risk aversion bounds: a correction

A recent paper by Hardaker et al. (The Australian Journal of Agricultural and Resource Economics, 48, 2004a, 253) and book by Hardaker et al. (Coping with Risk in Agriculture, 2004b) describe a procedure for determining an efficient set from among a set of random alternatives. This procedure, called stochastic efficiency with respect to a function (SERF), is claimed to make the same assumption concerning the risk aversion measures as does stochastic dominance with respect to a function (SDRF). This is claim is incorrect. SERF imposes an additional requirement on the risk aversion measures of the decision makers. Both procedures assume a lower and an upper bound on risk aversion, but SERF also assumes that all risk aversion measures are of the same functional form as these lower and upper bound functions. This additional strong requirement on risk preferences implies that the efficient set identified under SERF is usually smaller than that identified using SDRF.     

A model of local labor market regulation of China in the transition period

With the establishment of labor market of China, market is playing a more and mare important role in allocation of human resources. However, with the transition of economy in China and industrial upgrading in recent years, many labor problems have occurred which do harm to the sustainable development of local economy. The paper researches on the labor market issues of China from the perspective of local labor market regulation. Firstly, it reviews the theories of local labor market regulation. And then the main components of local labor market regulation of China are identified and the evaluation index system is established. The results of analysis of the calculated output show that （1） the local labor market regulation of China has an obvious character of gradient distribution geographically and decreases gradually from east to west; （2） of all the regulations, the regulation of the development of human capital has the most significant impact on local economy currently which is followed by the regulation of labor relation and the regulation of market participation.

新型城镇化背景下郑州市新生代农民工城市定居意愿影响因素研究

[目的]当前,推进新型城镇化建设已经成为国家健康快速发展的紧要问题。李克强总理在2015年全国人大会议上作政府工作报告时提出"以人为本的新型城镇化",强调城镇化建设中人的核心地位,在人的因素中新生代农民工是推进新型城镇化的最重要力量,他们的居留意愿成为决定新型城镇化的现在与未来成败的关键因素。因此,研究新生代农民工城市定居的意愿特征以及影响因素就具有很强的现实意义。[方法]通过调查问卷和实地访谈的形式对郑州市新生代农民工进行调研,在以第一手资料为基础的提前下,运用随机森林模型,从个人因素、家庭因素、制度因素和社会文化等4个方面中的24个因素实证分析影响郑州市新生代农民工留城意愿的特征和因素。[结果]影响新生代农民工留城意愿最显著的要素依次是从事职业类型、在城市工作时间、个人收入、家庭收入因素、是否参加城镇养老保险和是否享受城镇住房公积金。[结论]文章有针对性地提出发展教育、增加家庭收入和改善社会福利等解决问题的措施。
