Olive Oil Consumption in Greece: A Microeconometric Analysis

In this paper, the factors affecting at-home demand for three types of oils and fats in Greece, with emphasis on olive oil, are investigated using the linear approximation of the Almost Ideal Demand System and family budget survey data. To overcome the econometric problem created with the existence of zero expenditure, a generalization of the two-stage Heckman procedure is employed. In order to investigate the role of self-consumption, two different samples were used. The first includes all households; the second excludes those that acquire olive oil only from own production. According to the results, there are important differences in the first stage of the decision process between the two samples. Unlike the first stage, the second stage of the decision process found no important differences between the results for the two samples.     

最近10年来陶行知热点问题研究概观

当代陶行知研究的基本特点是以生活教育为中心,从理论研究走向实践探索,加强了国内与国外的联系,呈现出一种历史研究与现实借鉴、理论探讨与实践总结有机结合、互补共进的新局面。建国后,人们一直在争论的几个基本理论问题,到20世纪90年代已不再是人们的关注热点。现在学术界展开热烈讨论的问题主要有生活教育理论、创造教育思想、陶行知与中外文化教育、陶行知教育思想与当代中国教育的改革和发展等。     

市场调查:图书选题计划制定的关键

加强市场调查对提高图书选题策划的预测准确性作用极大。市场导向和市场反馈,将直接有助于出版机构了解市场的饱和点、空白点、热点、增长点和萎缩点,正确判断图书市场的现状和未来走势,进而在制订选题计划时更为合理地进行因势利导和科学决策。     

南京市中学生自尊心调查与分析

对南京市中学生的235份有效调查问卷表明,目前中学生对自尊状况的体验多数趋于“一般化”,但都较普遍地存在对自尊的焦虑感、敏感性、渴求性、盲目性、积极性并存的特点也很明显。中学生自尊与自尊心理的发生机制源自于教师与伙伴的外部评价,又源自于自身生理状况、能力。气质与童年经历的影响,中学生自尊与自卑心理的平衡机制存在于对理想自我标准的坚持、修正或放弃选择。学校教育培养中学生自尊心的有效切入点是:提高知识水平、培养羞耻感、锻炼意志力、培养尊重他人的品质。     

Nonresponse weighting adjustment using estimated response probability

To reduce nonresponse bias in sample surveys, a method of nonresponse weighting adjustment is often used which consists of multiplying the sampling weight of the respondent by the inverse of the estimated response probability. The authors examine the asymptotic properties of this estimator. They prove that it is generally more efficient than an estimator which uses the true response probability, provided that the parameters which govern this probability are estimated by maximum likelihood. The authors discuss variance estimation methods that account for the effect of using the estimated response probability; they compare their performances in a small simulation study. They also discuss extensions to the regression estimator.

What to do with “I Don't Know:” Elicitation in Ethnographic & Survey Interviews

When a researcher enters an interview, she has already construed it as being a standard type of communicative event. This article considers how a researcher's construal of a communicative event as either an ethnographic or survey interview shapes the production of information. Interview standards entail epistemological assumptions that directly inform the type of information sought and produced. I consider this process through a comparison of the elicitation techniques I employed in survey and ethnographic interviews conducted during research in Mexico. I draw on theory in linguistic anthropology on the nature of meaning in language, examining how dialogicality and interaction are essential to understanding the construal of communicative events.

民间话语下的历史审视——评莫言的《生死疲劳》

《生死疲劳》是莫言在艺术创作中向民间文化和民间资源的一次自觉的撤退和回归。小说通过章回体的运用,进行了一次整体的艺术突围。由此,民间的声音打破了历史的沉默,以往宏大叙事遮蔽之下的历史的另一面得以浮现出来。小说不仅展示了民间的生存状态,而且带来了对历史的重新审视。历史的"黑手高悬",一场场以历史的名义发动的无理性运动骚扰着人们,使得人们在与历史的较量中"生死疲劳"。这样,小说以轮回传说的书写形式,在消解现代性历史强力的同时,也表达出一种对生命的深切怜悯情怀。这或许就是莫言在《生死疲劳》中书写民间历史的真正情怀。     

Universal versus contextual effects on TQM: a triangulation study using neural networks

The objective of this study is to extend previous research on total quality management (TQM)-context-performance relationships and ‘fit’ using multiple methods. We combine artificial neural networks (ANNs) with structural equation modelling (SEM) to analyse several hypotheses and propositions. This is the first study in this area of research that utilises ANNs and a triangulation technique in the presence of several contextual factors. The SEM analyses suggest that company size and industry type may have contingency effects on some of the TQM practices and/or TQM-performance relationships. However, the ANN models have shown that these two contingency factors do not moderate TQM outcomes, implying that all organisations can benefit from TQM regardless of size and type. As well, these models show that formal TQM implementation and/or ISO certifications do not add any predictive power to the ANN models except in one case: TQM implementation and/or ISO certification added to organisational effectiveness and customer results to predict financial and market (F&M) results. The results further indicate that even though implementing TQM alone has a bigger impact on F&M results than obtaining ISO certification alone, combining the two will have an even greater impact on these results. Joint implementation leads to greater improvements in organisational effectiveness, which, in turn, has a positive effect on customer results and consequently F&M results. This is a unique finding within the context of moderator effects on TQM-performance relationships.
