McCloskey, economics as conversation, and Sprachethik

In writing about the 'rhetoric of economics' - particularlyabout the standards which prevent situations where 'anythinggoes' in argument - McCloskey takes an eclectic approach totwo philosophical positions, based on Rorty and Habermas respectively.But these positions, despite sharing some common aspects, alsodifferentiate themselves from each other sharply in importantways. In this paper, it is argued that this eclecticism of McCloskeyis not coherent, as a result of her not completely graspingthe fundamental differences between these two positions, andthat this incoherence has damaging implications for her projectof the rhetoric of economics.

Responding to Agenda 21: purchase and waste behaviour and the introduction of weight-based billing – a case study

In many societies unsustainable consumption patterns are currently being recognized as a critical problem receiving increasing public attention. Communities in many parts of the world are responding to United Nations Agenda 21 by attempting to increase public awareness about the necessity of increasing recycling, by increasing fees and taxes on products that are harmful to the environment, by introducing re-use systems, and by changing legislation. These are just a few examples of the kinds of measures that are being employed in an attempt to move towards an ecocyclic society. This article reports a case study from a Swedish municipality, Varberg, and the focus is on the relationship between household routines related to purchases of everyday commodities and waste management. In 1994, Varberg introduced a weight-based billing system for household waste and at the same time a green shopping campaign was launched by the authorities. The article reports findings from a study of 39 households, located in two different areas, a town area with rented apartments and a suburban area with owner occupied, one-family houses. Data have been obtained through interviews and weighing of household waste. Results show that there are important differences between these areas with respect to awareness of the information launched in the campaign, knowledge of the goals of the campaign and in the manners in which dwellers felt affected by the message conveyed. Households in the suburban area, for instance, had a better knowledge of green labels and what they stand for. There are also clear differences in concrete actions that can be taken by those living in the two areas. In the area with rented apartments, weight-based billing for the individual household is not possible, nor is composting a viable alternative. For the suburban families living in their own houses, there are a broad set of measures that could be taken to modify purchase behaviours and waste management towards more environmentally friendly alternatives.     

我国退耕还林产品形态及战略拓展

对中外退耕还林情况进行了概述,并从产品经济学角度出发,描述我国退耕还林工程产品的两种形态:即大范围自然生态区,国家买单;小范围局部生态经济圈,市场买单。同时提出4点建议:建立退耕土地银行制;完善有效的国家和个人利益平衡关系;加强退耕还林区非农人口输出和就业扶持;加强特色经济的多方位扶持和产业键延伸。     

城市圈建设过程中耕地保护AHP-SWOT分析及其策略选择——以湖北赤壁为例

研究目的:探讨城市圈建设过程中的耕地保护策略。研究方法:在实地调查的基础上,采用AHP-SWOT分析方法。研究结论:赤壁市耕地保护的自身优势有后备资源优势、异地占补平衡优势和法律制度保护优势等,相对劣势表现在耕地数量持续减少、耕地质量总体不高、产权不明晰、基层对耕地保护认识不足等,外部机遇有新一轮规划、三农问题备受重视、农业税的取消、农产品市场建设等,外部威胁来自城市圈建设占用耕地、退耕还林政策、农业结构调整、农产品比较收益较低等。AHP分析表明,城市圈建设占用耕地是最严重的外部威胁,耕地异地占补平衡则是要充分利用的自身优势,新一轮规划是推动赤壁市耕地保护的最佳外部机遇,耕地数量持续减少则是最不利的劣势。     

Changing science and ensuring our future

Science is not static but dynamic. A key challenge in its development is the reflection and accommodation of weaknesses, rather than just inherent strengths, both in its practices and institutional structures and settings. Pivotal to this are a range of issues including uncertainty, contextual issues, broader societal involvement, interdisciplinarity, and the enablement of reflexivity. These are not unrelated, autonomous concerns but intrinsically interdependent ones. For example extended characterisation and representation of uncertainty can facilitate integration between what have been regarded as separate: the technical and the contextual. This will require reflexive practices, often involving dialogue between scientists and the broader community. Much of this correlates with recent developments in social theory, such as conceptions of the risk society, and has significant implications for the relationship between the natural and the social sciences. This paper will identify, examine and describe these emergent changes to science and discuss their broader implications.
