The Welfare State as Safety Net in Migration Preferences: Empirical Evidence from an Experiment Among Dutch Master Students

Population Research and Policy Review - The welfare state can be perceived as a safety net which helps individuals adjust to situations of risk or transition. Starting from this idea of the welfare...     

Hill estimator of projections of functional data on principal components

Functional principal component scores are commonly used to reduce mathematically infinitely dimensional functional data to finite dimensional vectors. In certain applications, most notably in finance, these scores exhibit tail behaviour consistent with the assumption of regular variation. Knowledge of the index of the regular variation, α, is needed to apply methods of extreme value theory. The most commonly used method of the estimation of α is the Hill estimator. We derive conditions under which the Hill estimator computed from the sample scores is consistent for the tail index of the unobservable population scores.

关于大学英语写作教学实践的调查与反思

本研究以第二语言写作理论为指导,对五所高校的大学英语写作教学现状进行抽样调查。调查结果表明,学生写作能力欠佳的原因主要来自于教师的教及学生的学等不同的层面。为提高大学英语写作教学的质量,在教学中教师应该改变现有的教学模式,加强英语写作地位;合理设置写作任务,激发学生写作动机;加强目的语输入,扩大学生积极词汇量。     

Two-stage Huber estimation

In this paper we propose a new robust estimator in the context of two-stage estimation methods directed towards the correction of endogeneity problems in linear models. Our estimator is a combination of Huber estimators for each of the two stages, with scale corrections implemented using preliminary median absolute deviation estimators. In this way we obtain a two-stage estimation procedure that is an interesting compromise between concerns of simplicity of calculation, robustness and efficiency. This method compares well with other possible estimators such as two-stage least-squares (2SLS) and two-stage least-absolute-deviations (2SLAD), asymptotically and in finite samples. It is notably interesting to deal with contamination affecting more heavily the distribution tails than a few outliers and not losing as much efficiency as other popular estimators in that case, e.g. under normality. An additional originality resides in the fact that we deal with random regressors and asymmetric errors, which is not often the case in the literature on robust estimators.

The conflict over the use of information technology in South Korean schools

This article examines the heated debate over the National Educational Information System (NEIS) in South Korea. The NEIS has been introduced by the Ministry of Education. It collects information on every South Korean primary and secondary school in regional databases, including information regarding health records, religious backgrounds, military service, grades, attendance and other sensitive information relating to individual pupils and teachers. Using the cultural theory developed by Mary Douglas, Michael Thompson and Aaron Wildavsky, it is shown in which particular ways the rivals in this debate have been talking past, and misunderstood each other. On the basis of this cultural theory, a possible way out of this impasse is sketched.     

DIFFERENT AND SAME: FAMILY THERAPY WITH ASIAN-AMERICAN FAILIES

This paper is written for non-Asian family therapists who must deal with an increasing number of Asian-American client families. Unlike some writers in fthe field who advocate that client and therapist have the same ethnic background, the authors belive that cultural sensitivity can be learned. Several culturally important values are described, and suggestions on how to orient treatment to fit this client population are offered. A Detailed case example illustrates the treatment issues involued.
