新疆维吾尔族学生人体机能学考试成绩与MHK级别的相关分析

目的:探讨医学专业基础课程人体机能学成绩与中国少数民族汉语水平等级考试(MHK)级别的关系,分析原因,提高教学质量。方法:以新疆医科大学2011级602名维吾尔族学生为调查对象,分析人体机能学成绩与MHK关系。结果:MHK 3级的学生人体机能学平均成绩(31.6分,n=10)与4级的学生(39.03分,n=22)相比无统计学差异,与5级(47.24分,n=70)、6级(49.44分,n=140)、7级(52.88分,n=246)、8级(52.77分,n=114)的学生相比差异均有统计学意义。结论:维吾尔族学生汉语水平愈好则人体机能学考试通过率愈高,汉语水平对医学专业基础课程学习有一定的预测效果。     

One of us? Reaction formation and inclusion as a strategy in the ethnic state

Many states question how to manage burgeoning migration. This is particularly problematic for ethnic states whose foundation myths imagine the state as the home for the nation. In this paper, we argue that ethnic states engage a type of defense mechanism, ‘reaction formation’, as part of migration policy to distract attention from threats to the claimed ethnic homogeneity that undergirds the reason for the state's existence. Using Israel as a case of a planned ethnic state, we show how a state develops a spectrum of membership models to incorporate ‘others’ into the nation-state. We suggest that Israel could conceivably devise some arrangement to incorporate the several hundred thousand labor migrants currently resident there. We argue that the state is reluctant to recognize these migrants as ‘Israeli’ because to do so would reveal a hidden truth: Israel may be becoming more Israeli than Jewish and, thus, the recognition of labor migrants and their children provokes questions about Israel's very reason for existence, that is, being a Jewish state.     

The Effect of Product Development Restructuring on Shareholder Value

This article examines the effect of product development restructuring (PDR) on shareholder value. The results are based on a sample of 165 announcements made during 2002–2011. PDR announcements are associated with an economically and statistically significant positive stock market reaction. Over a two‐day period (the day of the announcement and the day preceding the announcement), the mean (median) market reaction is 1.63% (0.87%). The market reaction is generally positive regardless of the PDR purpose or action. Although the market reaction is more positive for higher R&D intensity firms, it is not directly affected by the firm's prior financial performance or whether the firm's primary PDR objective is to increase revenues or cut costs. However, the interaction between the firm's prior financial performance and its primary PDR objective is significant. For firms that are financial outperformers, the market reaction is more positive if the firm's primary PDR objective is to increase revenues. For financial underperformers, the market reaction is more positive if the firm's primary PDR objective is to cut costs.     

市场反应对盈利预测信息后续披露行为的影响——基于中国沪深A股的经验证据

以2006--2009年为研究窗口,选取在沪、深交易所上市的公司（仅限于发布业绩预告的上市公司）作为样本进行实证研究。结果表明：管理者在自愿披露盈利预测时并非仅仅因为好消息或坏消息来决定披露意愿,还要考虑市场是否合理反映了先前披露的信息;管理者首次披露盈利预测习性越早,其披露盈利预测意愿越强。

论民族文化互动的特点及本质

民族间的文化互动无时不在,然而对文化互动的特点及本质的认识经历了一个历史过程。本文从文化运作的实质出发,分析了文化互动的特点,提出了文化互动的耦合运作的观点。进而对丈化互动的本质进行探讨,认为文化互动是一个对等的持续过程,是一个从无序到有序的不断调适过程,是民族间相互吸收相互借鉴的过程,
从而形成了“你中有我,我中有你”的人类不可孤立存在的局面。

《食品生物化学》多媒体教学的实践

《食品生物化学》课程多媒体以大量的图像和动画等将微观、奥秘的生命现象以宏观、形象的方式展现,可大大提高学习效率。多媒体教学作为一种先进的教学手段,在表现自身优势的同时,也存在着明显的弊端。文章从《食品生物化学》多媒体教学的实践中,提出了一些提高多媒体教学质量的途径和方法。     

上市公司经营业绩在动量效应形成中的作用

为探讨上市公司经营业绩在动量效应形成中的作用,通过利用产业与资本市场的资产定价模型分解股票收益,按照三种收益水平构造动量投资组合并考察收益在持有期的表现,结果发现,经营业绩的横截面差异是形成动量与反转效应的必要条件;股票市场交易行为在不同时期对经营业绩的反应过度和反应不足促成了收益的动量与反转效应的形成。
