Environmental versus Human-Induced Scarcity in the Commons: Do They Trigger the Same Response?

We study appropriation strategies in common pool resources where extinction is a credible threat. Here we present an experimental study of the appropriation of common pool resources in a dynamic setting where resource availability depends on the initial environmental characteristics of the common resource and on human-induced resource depletion due to users’ appropriation patterns. Our results show that initial resource scarcity limits appropriation by inducing an initial caution among users that persists throughout of the game. Additionally, we find that subjects restrain their appropriation strategies when scarcity increases. However, this concern for resource scarcity is not enough to prevent resource depletion. Agents do not counteract the previous rounds’ appropriation strategies but follow the appropriation trend. High appropriation levels are followed by higher appropriation strategies, thus promoting the well known tragedy of the commons. Often concern for resource preservation is not great enough to limit appropriation.      

农业院校在新型农民培养中存在的问题

新农民就是有文化、懂技术、会经营的农民,是“能民”。建设社会主义新农村的宏伟目标能否实现,很大程度上取决于农民素质。农业院校在新农民培养中发挥了巨大的作用,但也存在着一些亟待解决的问题：农业院校的专业设置有离农的倾向,农业院校离农村渐行渐速,其大学生不愿到农村工作,“一村一名大学生”的培养有脱离“三农”的倾向。这些都需要采取措施予以解决。

"拆迁上访"警示城市化过热

本文认为,造成"拆迁上访"的深层原因是城市化过热,让拆迁户背负了城市化的成本.城市化的实质是投资活动,应遵循投资的一般规则.要解决城市化过热的问题,需要政府把城市化当成社会化的市场化的投资活动,转换自己在城市化中的角色与职能,宏观调控微观放手,并在城市化中自觉接受民主监督与法律约束.

Probability theory in fuzzy sample spaces

This paper tries to develop a neat and comprehensive probability theory for sample spaces where the events are fuzzy subsets of The investigations are focussed on the discussion how to equip those sample spaces with suitable -algebras and metrics. In the end we can point out a unified concept of random elements in the sample spaces under consideration which is linked with compatible metrics to express random errors. The result is supported by presenting a strong law of large numbers, a central limit theorem and a Glivenko-Cantelli theorem for these kinds of random elements, formulated simultaneously w.r.t. the selected metrics. As a by-product the line of reasoning, which is followed within the paper, enables us to generalize as well as to bring together already known results and concepts from literature.Acknowledgement. The author would like to thank the participants of the 23rd Linz Seminar on Fuzzy Set Theory for the intensive discussion of the paper. Especially he is indebted to Professors Diamond and Höhle whose remarks have helped to get deeper insights into the subject. Additionally, the author is grateful to one anonymous referee for careful reading and valuable proposals which have led to an improvement of the first draft.This paper was presented at the 23rd Linz Seminar on Fuzzy Set Theory, Linz, Austria, February 5–9, 2002.
