The Micro-Formation Mechanism of Trade Conflicts between Large Developing Countries: India’s Anti-dumping Action against China

Abstract

Employing Grossman and Helpman’s “protection for sale” model, this article uses data on anti-dumping actions from 1999 to 2009 to perform a quantitative analysis of factors influencing India’s determinations of anti-dumping duties against China, and reveals the micro-formation mechanism of economic conflicts between China and India. We find that the political power of India’s anti-dumping plaintiffs markedly increases the tariff level of its final determinations and that the relationship between the import penetration ratio and duty rates depends upon whether the plaintiffs are politically organized. Further, there is a significant positive correlation between India’s anti-dumping duty rates and its unfavorable trade balance with China. This indicates that in determining anti-dumping duties, Indian authorities are clearly influenced by the political clout of their domestic interest groups. They are also motivated by the desire to keep down China and gain the upper hand in the face-off between the “dragon and the elephant.”     

刑事审判程序拒绝预断的两条路径

各国刑事审判程序对预断的“拒绝”，可分为事前防止和事后排除两种途径。正因如此，认为“大陆法系职权主义刑事诉讼没有预断排除规则”的观点值得商榷。显而易见的是，对事前防止与事后排除的不同侧重，正是两种审判模式对待预断的区别之处。预断的作用机制，在心理学上可用“首因效应”来解释，从预断的发生、防止和排除三个方面入手进行分析十分必要，由此得以阐明两种审判模式拒绝预断的不同进路。并且从法制国家的程序设置来看，拒绝预断只是保障公正审判的诸多手段之一。     

克服晕轮效应,做好辅导员工作

随着社会的不断发展,辅导员工作逐步呈现出多样化、复杂化、困难化的趋势。正确地认识、了解、掌握并利用心理效应,在辅导员工作中往往会产生意想不到的效果。晕轮效应是一种普遍的心理错觉,在思想政治教育过程中比较常见,它的负面效应要远远大于正面效应。对于这种负面影响比较大的心理效应,我们要做到首先从理论上了解,继而在实践中避免,这样才能防止落入这些负面效应的恶性怪圈,让辅导员工作达到一个新的高度。

OPTIMAL SOFTWARE RELEASE POLICY BASED ON MARKOVIAN PERFECT DEBUGGING MODEL

In this paper we consider a Markovian perfect debugging model for which the software failure is caused by two types of faults, one which is easily detected and the other which is difficult to detect. When a failure occurs, a perfect debugging is immediately performed and consequently one fault is reduced from fault contents. We also treat the debugging time as a variable to develop a new debugging model. Based on the perfect debugging model, we propose an optimal software release policy that satisfies the requirements for both software reliability and expected number of faults which are required to achieve before releasing the software. Several measures, including the distribution of first passage time to the specified number of removed faults, are also obtained using the proposed debugging model.     

Social Activity,School-related Activity,and Anti–substance Use: Media Messages on Adolescent Tobacco and Alcohol Use

In this article, we present the effects of three hypothesized protective factors—social activities, school-related activities, and anti–substance use media messages—on adolescent tobacco and alcohol use. Data were drawn from the “Monitoring the Future” research project, which was conducted by the Institute for Social Research at the University of Michigan. The sample included 2,551 twelfth-grade students. The results of the structural equation model showed that exposure to media anti-drug messages had an indirect negative effect on tobacco and alcohol use through school-related activity and social activity. The results suggest that comprehensive ecological interventions encompassing media, family, and school can increase the preventive effects of adolescent's substance use.     

The Social Ecology of Child Development in the Mexican American Population

Abstract

This article explores the influence of contextual factors on the developmental outcomes of Mexican American children. The contextual structure of child development is conceptualized as a complex system of environments, including the socio-demographic, social service, academic, and parental home environments. Based on an extensive review of the current theoretical and empirical literature, we find that the disadvantaged social position of Mexican American children has detrimental implications for all other aspects of their environment, thus hindering their development. In addition, although Mexican American parents are highly competent in providing a nurturing and culturally-rich environment, there is a often a discontinuity between the home environment and both the academic and the social service environments.     

Estimability and Linear Hypotheses

A proposition is given which provides an easily justified reason as to why attention should be confined to estimable parametric vectors when formulating linear hypotheses. The possibility of justifying one's linear estimation effort on the estimable parametric functions via an identifiability condition is also mentioned.
