企业生态质量控制评价指标体系研究

生态质量管理理念的产生是可持续发展理论向质量管理理论渗透的结果。在介绍生态质量管理理念产生的基础上,提出从环境、顾客生态满意度、职业安全健康和企业生存能力四个方面评价企业的生态质量管理,并设计了相应的指标体系。     

创作灵感的新解读

灵感与高峰体验是紧密联系的,高峰体验可以把人带入一种澄明空灵的虚静状态。"虚静"与佛教的"参禅"相似,可澄清致远,从心底抒写。高峰体验不是哪一个人的专利,它在每一个人身上都可发生。要善于抓住,否则一闪即逝。     

Flipping and ex post aggregation

We show that Bayesian ex post aggregation is unstable with respect to refinements. Suppose a group of Bayesians use ex post aggregation. Since it is a joint problem, each agent's problem is captured by the same model, but probabilities and utilities may vary. If they analyze the same situation in more detail, their refined analysis should preserve their preferences among acts. However, ex post aggregation could bring about a preference reversal on the group level. Ex post aggregation thus depends on how much information is used and may keep oscillating (“flipping”) as one keeps adding more information. Received: 16 April 2002/Accepted: 27 May 2002     

On strategy-proofness and essentially single-valued cores: A converse result

In a general model of indivisible good allocation, S?nmez (1999) established that, whenever the core is nonempty for each preference profile, if an allocation rule is strategy-proof, individually rational and Pareto optimal, then the rule is a selection from the core correspondence, and the core correspondence must be essentially single-valued. This paper studies the converse claim of this result. I demonstrate that whenever the preference domain satisfies a certain condition of `richness', if the core correspondence is essentially single-valued, then any selection from the core correspondence is strategy-proof (even weakly coalition strategy-proof, in fact). In particular, on the domain of preferences in which each individual has strict preferences over his own assignments and there is no consumption externality, such an allocation rule is coalition strategy-proof. And on this domain, coalition strategy-proofness is equivalent to Maskin monotonicity, an important property in implementation theory.

隆线溞(Daphnia carinata king)的呼吸代谢测定

本文用Winkler法测定隆线溞(Caphnia carinata king)不同龄期个体的耗氧量及二幼龄个体在不同温度下的耗氧量。测得幼龄与成龄两阶段,其耗氧量分别以4.88×10~(-2)与1.695×10~(-1)的速率随体重增加而增大,耗氧率则分别随体重的增加而逐渐降低;在常温下,隆线溞耗氧量Y与温度X呈Y=3.69×10~(-3)×1.07~x的指数函数关系,由此得到,17℃—19℃是隆线搔生长速率快而耗氧量较小的最适人工培养温度。

高校建设应法治德治并举

为深入贯彻依法治国和以德治国相结合的治国方略,高校建设也应依法治校与以德治校并举,这是由当前教育中存在的问题,教育的目标机制决定的。实现这一治校方略应分别制定举措,并将两者紧密结合起来,不能忽视其中任何一个方面,要做到两手抓、两手都要硬。
