开心一刻

不知道是谁的早上,我拿着内裤质问老公:在你衣服兜里掏出来的!说吧,你昨天去哪了?老公摸着脑门,想了半天,冷静地说道:昨天和几个朋友喝酒,洗了个澡,喝了第二场,然后就回来啦,我也不知道这内裤是谁的呀!我上去就给了他一脚,骂道:你不是说你昨晚在单位加班吗?不知道是谁的!我告诉你,是老娘的!     

A Comparison of Extra Market Benefit Evaluation Techniques: A Reply

Van Kooten identifies what he considers four "major problems" with our paper. The first has to do in part with the discrepancy between WTP and WTAC. He suggests we misinterpreted Gordon and Knetsch with the sentence, "Economic theory suggests that these two values are estimates of consumer surplus and should be similar" which was taken out of context by Van Kooten. Our reference to Gordon and Knetsch followed the sentence, "Some have stated that this difference is due to an income effect but even this factor fails to provide for the vast difference in these measures (Gordon and Knetsch)." The message in the paragraph (p. 402–403) containing these two sentences is the following: In theory the two measures differ slightly because of differences in income or wealth effects. Yet large empirical differences have been observed and cannot be supported solely on the basis of income and wealth effects. We therefore must take strong exception to Van Kooten's statement that "… it is best to attribute most of the difference between WTP and WTAC to the income effect (Bockstael and McConnel 1 1980, p. 61)." One can find in the literature statements such as the following: "Further, the magnitude of the value at issue should rule out the income or wealth effect as being an adequate explanation of the observed variation between the two measures" (Knetsch and Sinden 1984; see also Bishop et al., 1984).     

A Comparative Static Analysis of Welfare Impacts of Supply-Restricting Marketing Boards: A Comnent

Van Kooten and Spriggs (VKS) make a useful contribution to our understanding of the basic theory of the firm as applied to quota restrictions on output, at least as far as their short-run analysis is concerned. However, it is the long-run analysis which is more relevant for judging the welfare implications of the policy, and it is here that the VKS analysis is open to question. This comment puts forth an alternative view. In so doing it also draws attention to some of the more important policy implications of the analysis.     

城市地质学综述

城市三维地质条件的调查主要采用机械钻探与地球物理勘探相结合的方法,通过收集大量资料,建立比较完整的数据库,并借助于地理信息系统,建立三维地质模型;城市地质灾害调查需综合运用遥感、地质和地球物理勘探方法,以编制城市灾害分布及预测图,并进行风险评估;城市环境污染调查则主要运用勘探地球化学技术,在区域地球化学填图的基础上,结合各项地质环境指标监测,采用风险评估方法,以评价和预测环境污染状况及其未来趋势。城市地质各项成果向数字化、可视化的信息产品转化,为更多用户提供信息服务,促进城市规划、土地利用与开发,是现代城市地质学发展的必由之路。     

猕猴桃发展小史

现今水果市场上的猕猴桃主要是指中华猕猴桃 (Ａｃｔｉｎｉｄｉａｃｈｉｎｅｎｓｉｓ) ,这是当今大家都很熟悉的一种果树。实际上我国各地叫猕猴桃的植物有多种。据我国植物学家调查 ,在我国分布的猕猴桃属的植物有5 2种以上 ,其中有不少种类的果实都可以食用 ,有些味道比中华猕猴桃还要甜美一些 ,如毛花猕猴桃(Ａ .ｅｒｉａｎｔｈａ)。还有的经育种专家培育 ,成为能抗低温、对病害有免疫性的优良品种 ,如狗枣猕猴桃(Ａ .ｅｏｌｏｍｉｋｔａ) ① 。我国西南是这类植物的分布中心 ②。我国现在广为栽培的中华猕猴桃 (Ａ .Ｃｈｉｎｅｎｓｉｓ)…

THE FARM AS A FAMILY BUSINESS: A REVIEW

Although the great majority of UK farms are run as family businesses, the family dimension of these businesses is frequently neglected. There are nevertheless important inferences to be drawn from studying the farm family, its forms and functions, and the way that the family and the business interact. This calls for a multidisciplinary approach and the review attempts to draw together insights from industrial economics, social anthropology, history and rural sociology as they apply to the farm family business. It then relates these insights to considerations of the family development cycle, processes of inheritance and succession, roles of farmers' wives and multiple-job farming families. The literature review points to opposing tendencies within the population of farm businesses. Family forms of organisation and relationships may have become less relevant to farming at the lower end of the size scale but more relevant to the conduct of a successful large farm business.
