面对全球化挑战的知识分子

全球化具有不同的层面,这些层面之间是相互影响、相互作用,甚至是相互冲突的,例如经济的全球化与社会正义的全球化。因此,对全球化进行单纯的批评和支持是没有意义的,只有理性的分析才能阐释多元全球化。在此意义上,知识分子应担负起我们时代自我理解的重要使命。

Estimation of the correlation coefficient in probability proportional to size with replacement sampling

g of the population correlation coefficient has been suggested in case of probability proportional to size with replacement sampling. The asymptotic bias, variance and the estimate of the variance of the estimator r_g have been obtained. A comparison of this estimator has been made with the estimator r given by Gupta et al (1993) and usual estimator r₁ for PPSWR sampling. The proposed estimator r_g satisfies the condition −1≤r_g≤1 which the estimator r does not satisfy. Received: September 1, 1999; revised version: May 29, 2001     

Extended complex error correction models for seasonal cointegration

In this paper, we extend the complex error correction model (ECM) of [Cubadda, G. (2001). Complex reduced rank models for seasonally cointegrated time series. Oxford Bulletin of Economics and Statistics, 63, 497–511] to models with two types of deterministic terms: (i) restricted seasonal dummies and constant; (ii) restricted seasonal dummies and unrestricted constant. These types of deterministic terms are most frequently adopted in the analysis of seasonal cointegration by many practitioners and researchers, because the other type–where all seasonal dummies and constant terms are unrestricted–may yield oscillating trends. We obtain the limiting distribution of the likelihood ratio (LR) test for the seasonal cointegrating (CI) rank in the extended models. We also provide asymptotic and finite critical values for the test.

复杂理论:二语习得研究的新视角

二语习得/发展可以被看成异质的、动态变化的、非线性的、自适应的、开放的复杂系统,系统中各要素交互作用引起了二语习得发展的变化。"复杂理论"就是对系统中各要素的变化、要素间交互作用的变化、系统轨迹的变化及系统与其它系统的关系进行描述、解释和预测。在复杂理论的新视角下,二语习得领域中值得探索的方向包括语法中的"怪现象"、二语能力的测试、二语习得系统的建模、二语发展轨迹的个体内差异研究、方法论研究等。     

Ethical values and social change: Mahatma Gandhi,Martin Luther King,Jr. and Ahn Chang Ho

Mahatma Gandhi, Martin Luther King, Jr. and Ahn Chang Ho exemplify the leaders who brought social change by applying their belief in non-violence and love of humanity to the accomplishment of their respective goals. Gandhi’s goal was securing India’s independence from British colonialism, and King’s was to rid America from racial segregation. Irony about England and the US was that they had a long history of commitment to human rights and democracy. Hence, Gandhi and King’s struggle for justice focused on reminding their adversaries of their hypocrisy, a gulf between their commitment and actions. Ahn had to deal with Japanese colonialists, who had little respect for and commitment to human rights and civil liberties. Ahn’s job was, therefore, more complicated than Gandhi’s or King’s. Ahn insisted that for the Koreans to achieve their political independence from Japan, they must build their inner strength first, and do this by self-cultivation of moral and ethical values. Building moral and ethical strength ought to also accompany receiving modern education, acquiring marketable skills, and building financial resources. At the same time he condoned the militant approach to the Korean independence movement, as necessary. Ahn was a complex figure, a blend of a moralist, a strategist, and a pragmatist.     

From concerned citizens to activists: a case study of 2015 South Korean MERS outbreak and the role of dialogic government communication and citizens’ emotions on public activism

ABSTRACT

This study investigated the cognitive-affective-behavioral sequence of public activism by examining the role of citizens’ perception of government dialogic communication during a national pandemic crisis. Through a case study of the 2015 Middle-East respiratory syndrome (MERS) outbreak in South Korea, the results of a survey of 400 South Korean citizens showed that distrust in government and a high level of situational uncertainty were significantly mitigated by citizens’ perceptions of government efforts for dialogic communication during the crisis. Conversely, when the perception of dialogic government communication was low, high distrust in government increased cynicism, anger, and anxiety among citizens; high situational uncertainty led to higher levels of anger and anxiety, but not cynicism. Consequently, the findings showed that anger, anxiety, and cynicism significantly motivated citizens’ intentions to take actions against the government. Direct and positive effects of anger, anxiety, and cynicism on activism participation were not found and were mediated by the citizens’ activism intentions.     

Estimation for semiparametric varying coefficient models with different smoothing variables under random right censoring

In this paper we study a semiparametric varying coefficient model when the response is subject to random right censoring. The model gives an easy interpretation due to its direct connectivity to the classical linear model and is very flexible since nonparametric functions which accommodates various nonlinear interaction effects between covariates are admitted in the model. We propose estimators for this model using mean-preserving transformation and establish their asymptotic properties. The estimation procedure is based on the profiling and the smooth backfitting techniques. A simulation study is presented to show the reliability of the proposed estimators and an automatic bandwidth selector is given in a data-driven way.
