关于含参变量无穷积分的绝对一致收敛的注记

本文从一个反例 ,证明了即使∫∞af(x ,t)dt绝对收敛且一致收敛 ,但不能推出∫∞a |f(x ,t) |dt一致收敛。     

大学生群体对社会工作职业声望评价探析——以四川农业大学本科生为例

为了解社会工作目前的职业声望,本文通过问卷调查了作为社会先进群体的大学生对社工的职业声望评价。调查结果显示,大学生自身所持有的价值观、择业要求会影响对职业的评价,对社工本身的了解程度也是影响因素之一。笔者因此建议通过大力加强社工价值教育,扩大舆论宣传和提高社工福利等措施来提高社工的职业声望。

The Gaussian Mixture Dynamic Conditional Correlation Model: Parameter Estimation,Value at Risk Calculation,and Portfolio Selection

A multivariate generalized autoregressive conditional heteroscedasticity model with dynamic conditional correlations is proposed, in which the individual conditional volatilities follow exponential generalized autoregressive conditional heteroscedasticity models and the standardized innovations follow a mixture of Gaussian distributions. Inference on the model parameters and prediction of future volatilities are addressed by both maximum likelihood and Bayesian estimation methods. Estimation of the Value at Risk of a given portfolio and selection of optimal portfolios under the proposed specification are addressed. The good performance of the proposed methodology is illustrated via Monte Carlo experiments and the analysis of the daily closing prices of the Dow Jones and NASDAQ indexes.     

The limitations of using school league tables to inform school choice

Summary. In England, so-called 'league tables' based on examination results and test scores are published annually, ostensibly to inform parental choice of secondary schools. A crucial limitation of these tables is that the most recent published information is based on the current performance of a cohort of pupils who entered secondary schools several years earlier, whereas for choosing a school it is the future performance of the current cohort that is of interest. We show that there is substantial uncertainty in predicting such future performance and that incorporating this uncertainty leads to a situation where only a handful of schools' future performances can be separated from both the overall mean and from one another with an acceptable degree of precision. This suggests that school league tables, including value-added tables, have very little to offer as guides to school choice.     

基于顾客感知价值的顾客满意研究

越来越多的企业将顾客满意视为最重要的成功因素。企业界和学术界以往把产品或服务质量作为决定顾客满意的主要驱动因素,比较忽视顾客在交易全过程各种形式的付出。顾客感知价值是顾客对产品与服务在权衡利得与利失基础上形成的评价与偏好,是决定顾客满意的重要前提。顾客感知价值与顾客满意间存在层次上的互动,从而形成不同层次的顾客满意。顾客感知价值为企业真正实现顾客满意管理提供了新的认识途径和管理基础。

旧学新知——朱熹思想及其价值综论

当代中国、亚洲乃至世界,正处于政治、经济、文化和环境巨大变化的崭新时期;各国人民面临着相近相通的社会问题、思想困惑和精神挑战。为了超前和卓有成效地应对现实与未来,我们需要从历经数千年深厚积淀的历史文化宝藏之中汲取思想智慧和正负面经验,以此作为创造中华民族未来新文化的本土精神根基,进而借此深入推进中国社会的精神文明和现代化事业。为此,我们需要对国学的核心内容——儒学、特别是以朱熹为代表的宋代理学进行批判性认知和建设性阐发,以便深刻体认朱熹博大精深的思想脉络,完整辨析他的学术品格与良知美德,全面认识其核心话题的价值,切实领会其伦理道德的意义,觉解其经学哲学的精华,理解并批判借鉴其有关改善政治经济的思想之道,把握并光大其为人为学的闪光特征,进而取得自下、自迩、累土、足下的社会体用功效。
