Tensions in co-evolutionary processes: Three Swedish seed organizations in the 20th century

This paper addresses the issue of which societal actors have the capability and willingness to finance and organize search processes, in order to introduce commercial innovations, over a longer time period. The long-term development of agriculture depends upon innovations within a variety of technologies, markets, organizational forms as well in the seeds themselves. This involves points of tensions between continuity and change as well as co-evolutionary processes organized around the innovation processes. This article explores the tensions between continuity and change, by focusing on three dimensions, namely: (1) regional location versus global interactions; (2) static specialization versus experimentation in knowledge and products; and (3) relative success versus failure. The historical development of three Swedish agricultural seed organizations, Hilleshög, Svalöf and Weibulls, during the 20th century, provides an empirical probe within which to address the more fundamental theoretical problems.     

浅议学校文书档案的齐全完整

文书档案的齐全完整是学校档案工作的基础,同时也反映出一个学校管理质量的高低。文章阐述了文书档案的形成过程,从文书档案的利用及文书档案反映学校发展的历史两个方面分析了文书档案收集齐全完整的重要性,提出了“群体的档案意识”的观点,并在此基础上论述了院领导、专职档案员、兼职档案员及学校每一位教职工的档案意识对确保文书档案收集齐全完整所起的作用。     

基于小g函数法的客户侧供电可靠性分析的研究

针对目前我国对于供电可靠性只统计到中压客户,并不能全面反映各类用电客户实际的供电可靠性的缺陷,为了找出计及中压与计及低压两者之间供电可靠性的差异及其变化的规律,本文对低压客户侧供电可靠性的主要评价指标、基础数据的建立及各类停电数据的采集进行了分析,提出了采用"小g函数法"进行差异化分析,且以仿真数据输入的方式计算了同一外部环境和停电事件下的两种可靠性指标,经分析比较后得出了计及中、低压客户的供电可靠性指标变化差异的规律,为计及低压客户供电可靠性计算方式提供了理论依据。

The Role of Analysts’ Forecasts in Accounting-Based Valuation: A Critical Evaluation

This paper critically evaluates the use of analysts forecasts in accounting-based valuation. Specifically, I assess the usefulness and the limitation of analysts forecasts in predicting future earnings and in explaining the market-to-book ratio, in light of a comprehensive set of 22 explicit information items, including: economic rent proxies, conservative accounting proxies, earnings quality signals, transitory earnings proxies, industry characteristics, and risk and growth proxies. While analysts forecasts capture 45–83% of the information from these sources depending on model specifications, they do not appear to fully incorporate certain information items. In particular, proxies for conservative accounting and transitory earnings are incrementally useful in predicting future earnings; proxies for economic rents, conservative accounting, and risk are incrementally useful in explaining the market-to-book ratio. Collectively, these results validate the use of analysts forecasts as a parsimonious proxy for forward-looking information in accounting-based valuation and suggest how to improve on their use.JEL Classification: D4, G12, M4     

An alternative direct proof of Gibbard’s random dictatorship theorem

We present an alternative proof of the Gibbards random dictatorship theorem with ex post Pareto optimality. Gibbard(1977) showed that when the number of alternatives is finite and larger than two, and individual preferences are linear (strict), a strategy-proof decision scheme (a probabilistic analogue of a social choice function or a voting rule) is a convex combination of decision schemes which are, in his terms, either unilateral or duple. As a corollary of this theorem (credited to H. Sonnenschein) he showed that a decision scheme which is strategy-proof and satisfies ex post Pareto optimality is randomly dictatorial. We call this corollary the Gibbards random dictatorship theorem. We present a proof of this theorem which is direct and follows closely the original Gibbards approach. Focusing attention to the case with ex post Pareto optimality our proof is more simple and intuitive than the original Gibbards proof.Received: 15 October 2001, Accepted: 23 May 2003, JEL Classification: D71, D72Yasuhito Tanaka: The author is grateful to an anonymous referee and the Associate editor of this journal for very helpful comments and suggestions.

论《关雎》英译的解构主义视角

本文作者从解构主义视角对理雅各、韦利、许渊冲和汪榕培与任秀桦等人所译的《关雎》四种不同英文译本中选取的部分内容进行了比较分析与研究。四种译本的风格韵味各有不同,首先表明了译者本人不可避免要受到自身所处时代社会政治经济生活环境和自我身份以及其他因素的影响。任何译者要想将原文《关雎》作为绝对标准而在译文中完全再现是不可能的,因为每位译者都会无一例外地根据自己对《关雎》的解读来进行翻译操作,从而在译入语文本之中＂延异＂出《关雎》原作的新生命。
