Financial Liberalization and Stock Price Behaviour in Asian Emerging Markets

This paper exhibits tests of the random walk hypothesis and market efficiency for seven Asian emerging markets as a result of the influence of financial market integration. Random walk properties of equity prices influence the return dynamic and determine the trade strategies of investors. To examine the stochastic properties of local index returns and to test the hypothesis that stock market prices follow a random walk, the single variance ratio tests of Lo and MacKinlay, as well as the multiple variance ratio test of Chow and Denning are employed. The multiple statistical comparison of variance ratios is based on the Studentized Maximum Modulus distribution with control of the joint-test’s size. The weak-form market efficiency is also tested directly, using a nonparametric runs test. These tests are particularly useful for investigating stock prices the returns of which are frequently not distributed normally. Documented evidence shows that, from the perspective of local investors, weekly stock prices in major Asian emerging markets do not follow a random walk in the pre-liberalization period. However, in the post-liberalization period the weak-form efficiency hypothesis is generally adopted at the 5% level except for the smaller stock markets of Indonesia and Thailand. These empirical findings suggest that financial integration affects the return predictability in such a way that domestic investors might not be able to develop trading strategies allowing them to earn abnormal returns.

在对司法心理测试进行的实验研究和现场研究中,司法心理测试用于侦破内盗案件成功率很高,内盗案件的性质及测试条件适合使用心理测试技术,被测人所处地位以及劝导说服式的测后谈话对被测人的心理影响很大。     

中国犯罪心理测试技术研究应用现状与展望

中国犯罪心理测试技术的研究与应用,必须立足中国本土的实践。实践证明,照抄照搬美国测谎理论和方法,仿制美式仪器简单机械地应用是十分错误的。在党中央提出加强科技自主创新的今天,《中国犯罪心理测试技术应用教程纲要》一书,已成为我国自主研创的基本理论和基本方法的结晶,已成为大学相关专业研究生、本科生、专科生的必读教材。中国自主研创的犯罪心理测试技术理论和方法亟需推广和普及。     

HLA 及其在法医学上的应用

HLA 是迄今人类最复杂的遗传多态性系统,其在法医学上的应用,包括亲子鉴定和个人识别的重要性日益被认识。作者等对血痕、血清和唾液的 HLA 测定的研究结果证明:(1)血痕中存在较强的抗补体作用。应用淋巴细胞毒抑制试验测定血痕的 HLA 时,增加补体用量可使测定的正确率达100%,经90天的血痕仍能完全正确检出 HLA 型。(2)血清的 HLA 测定是可行的,这对远道送检血清及尸体血清测定 HLA 有一定价值。(3)唾液中有可溶性 HLA 抗原存在。

A field experiment on ethnic discrimination among local Swedish public officials

This study presents an innovative field experiment exploring ethnic discrimination in contacts between local public officials and members of Swedish society. Using a correspondence study design, fictitious individuals with Arabic- and Swedish-sounding names contacted Swedish municipalities via email, asking questions about access to preschools. The findings indicate disadvantageous treatment of individuals with Arabic-sounding names in terms of the informal tone of the replies, as Swedish-sounding names were replied to in a friendlier, more welcoming way. Regarding the more formal aspects of the emails – i.e., whether they were replied to at all and the questions posed were directly answered – no statistically significant signs of discrimination emerge (although differences were of some substantial size, to the disadvantage of Arabic-sounding names). Still, informal disadvantageous treatment is sufficient cause for concern and noteworthy in the case of Sweden, considering its reputation as being egalitarian, immigration friendly and democratically well functioning.
