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。     

史料引用致误原因分析

史料是史学研究的基础.但自古以来,由于种种原因,错误的或者事实模糊不清的史料很多,如果不作必要的考证鉴别,很难获得科学的研究成果.造成史料引用致误的原因是多方面的,归结起来主要有:(1)史料本身无误,由于没有正确理解原意或者标点不正确而致误;(2)史料本身无误,由于引用者推断不确而致误;(3)史料内容比较含蓄,由于引用者缺乏深入辨析而致误;(4)没有直接引用原书而致误;(5)因版本不善而造成史料的错误或脱漏;(6)史料本身就有错误.     

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。     

从《诗经》情歌看先民的宗教情结

情歌在<诗经>中占有非常重要的地位,其情节形象地再现了古代社会隆重的祭高禖仪式,这一仪式与先民的生殖崇拜密切相关,不仅反映了人们自由、奔放的性爱意识,揭示了人们对生命的热爱和重视,而且寄托着远古民族浓重的宗教情结,从而使<诗经>具有了深厚的人类学价值和深远的文化意蕴.     

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.     

试论晚年白居易的自足、闲适思想

源于老庄思想的自足、闲适心态 ,是晚年白居易之所以能在洛阳实现身心自然合一的“中隐”生活的心理基础。因为自足 ,才会身心闲适 ,适又以闲为前提条件。其闲适诗中失落了表现社会责任的儒家精神。

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.
