比较新闻史学刍议

新闻事业史的研究是新闻学研究的重要组成部分,长期以来已形成一套传统的研究方法和思路。随着新闻事业的不断发展、融合、交叉,新闻史学的研究在方法论上正酝酿着新的突破和发展。本文以即将来临的２１世纪学术研究的特点为基础,对比较新闻史学这一新方法进行了介绍和探讨

Revisiting the stock price impact of quality awards

In an event study, Hendricks and Singhal [Hendricks KB, Singhal VR. Quality awards and the market value of the firm: an empirical investigation. Management Sci 1996;42:415–36.] find evidence that firms that win quality awards are further rewarded with a stock price increase on the day of the award announcement. We revisit Hendricks and Singhal (1996), extend their research and find four reasons why management, owners and analysts should be cautious about expecting an abnormal return when a firm wins a quality award. First, in our sample of Baldrige Award winners, the evidence of a stock price response on the announcement day is only marginally significant. Second, in our sample of State quality award winners, the announcement day relationship between stock returns and winning awards is not significant. Third, in the most recent subperiod, 1992–1997, we find no evidence of positive abnormal returns. Fourth, the marginally significant Baldrige results are actually driven by just four companies. A company-by-company microanalysis reveals that only 50% of the award winners experienced positive abnormal returns. The diminishing stock price response on event day does not necessarily imply a lack of stockholder rewards. Evidence from other studies suggests that the stockholders are rewarded for successful total quality management (TQM) implementation, but the rewards can come long before and after the formal award is presented. From a shareholder value perspective, TQM still matters but the award ceremonies may not.     

Non-parametric estimation of the long-range dependence exponent for Gaussian processes

We consider a class of long-range-dependent Gaussian processes defined in a semiparametric framework. We propose a new estimator of the long-range dependence parameter, based on the integration of the periodogram in two windows. We show that it is asymptotically Gaussian and calculate the rate of convergence. We optimise parameters defining the window function for the minimum mean-square-error criterion. In a Monte-Carlo study, we compare the proposed estimator with previously studied estimators.     

The zero-inflated Poisson model and the decayed, missing and filled teeth index in dental epidemiology

For frequency counts, the situation of extra zeros often arises in biomedical applications. This is demonstrated with count data from a dental epidemiological study in Belo Horizonte (the Belo Horizonte caries prevention study) which evaluated various programmes for reducing caries. Extra zeros, however, violate the variance–mean relationship of the Poisson error structure. This extra-Poisson variation can easily be explained by a special mixture model, the zero-inflated Poisson (ZIP) model. On the basis of the ZIP model, a graphical device is presented which not only summarizes the mixing distribution but also provides visual information about the overall mean. This device can be exploited to evaluate and compare various groups. Ways are discussed to include covariates and to develop an extension of the conventional Poisson regression. Finally, a method to evaluate intervention effects on the basis of the ZIP regression model is described and applied to the data of the Belo Horizonte caries prevention study.     

高等学校跨学科外语人才培养模式比较

通过对IS09000标准改进教学质量管理体系、教学改革指导的培养目标定位、跨学科外语师资队伍建设、三个层次培养方案的梳理与修订等不同特色院校的跨学科外语人才培养模式分析,其应立足于专业培养模式、课程设计、教学方法和学生自主学习能力等方面培养。对大连海洋大学、大连理工大学、大连外国语学院、东北财经大学等不同特色层次院校的跨学科外语人才培养模式进行比较发现,跨学科外语人才培养应该渗透到教师教学、学生自主学习,将学生的能力培养作为跨学科外语人才培养的核心内容。     

当前高校学风滑坡:现状、成因与对策

高等学校的学风滑坡现象令人忧虑。主要表现在缺乏基本的学习动力、严谨的学习态度、刻苦的学习精神、良好的学习道德四个方面。其矫正对策为:强化教学过程管理,培养学生严谨的学习态度;强化学分学籍管理,培养学生严明的纪律观念;强化学习诚信教育,培养学生优良的学习品德;强化基础素质教育,提高高校招生生源质量;强化社会综合治理,优化高校的办学环境。     

学风建设浅谈

学风问题是影响教学质量提高的重要问题之一。加强学风建设要各方面通力合作,共同努力。从社会背景、市场需求、高校体制、学生自身等各方面分析高校学风建设状况,提出改进措施,呼吁全民提高认识,注重以人为本,实施素质教育,加强学风建设。     

关于对藏式围棋研究与保护的探讨

在吐蕃时期,藏式围棋就已广为流传,是古代藏族民众日常娱乐的重要组成部分,为开发人的智慧、纯洁人的性情起到了积极作用。兼容了逻辑思维和形象思维为一体的、具有民族特色的藏式围棋随着时间的推移衰落了,目前在西藏很难见到藏式围棋活动,这项古老的民族传统棋艺正处于消失的境地。当下,我们应当对藏式围棋进行挖掘与整理研究,让古老的藏式围棋以新的方式、新的内容面向社会、面向未来,弘扬优秀民族传统文化。
