Utility of gambling II: risk,paradoxes, and data

We specialize our results on entropy-modified representations of event-based gambles to representations of probability-based gambles by assuming an implicit event structure underlying the probabilities, and adding assumptions linking the qualitative properties of the former and the latter. Under segregation and under duplex decomposition, we obtain numerical representations consisting of a linear weighted utility term plus a term corresponding to information-theoretical entropies. These representations accommodate the Allais paradox and most of the data due to Birnbaum and associates. A representation of mixed event-and probability-based gambles accommodates the Ellsberg paradox. We suggest possible extensions to handle the data not accommodated.      

住宅质量特性探析

现代住宅质量的内涵非常丰富,包括舒适性、安全性、方便性、经济性、环保性、生态性、人文性、幽雅性、抗灾性、符合性等特性。要全面把握住宅质量特性,深刻理解住宅质量特性内涵,应在住区选址、规划、设计、建设中,将现代理念融入“人—社会—自然”的复合生态系统中。     

国有资本营运机构与地方国有资产管理体制之落实

建立在公有制基础上的社会主义市场经济的核心是在推进市场运行机制的同时,完成经济运行载体的制度性构造。因与私人产权的运行逻辑不同,国有产权的实现需在宪政层面上展开。国有资本营运机构处于“政”、“企”的接口环节,完善国有资本营运机构的制度设计及规范其在现实生活中的重组,对于落实地方国有资产管理体制,实现政资分离、政企分开具有关键意义。

碳纳米管含量对Ti(C,N)基金属陶瓷组织性能的影响

研究了不同含量的碳纳米管对含适量稀土元素的Ti(C,N)基金属陶瓷组织性能的影响.对不同含量碳纳米管的试样分别于1400℃、1410℃、1420℃真空烧结,通过观察材料的显微组织及断口形貌,测试其抗弯强度及洛氏硬度,结果表明:加入质量分数w=0.3%～1%的碳纳米管时,碳纳米管w=0.5%时其组织较均匀,芯壳结构明显,抗弯强度及硬度均较高.

马来酸酐接枝聚乙烯改性氢氧化铝/聚乙烯体系性能研究

将马来酸酐与聚乙烯进行反应,红外光谱显示马来酸酐接枝到聚乙烯分子链上,然后用马来酸酐接枝聚乙烯处理氢氧化铝表面,将马来酸酐接枝聚乙烯处理的氢氧化铝与聚乙烯熔融混合后,考察流变、力学、阻燃性能及微观形态变化。结果显示,采用适量马来酸酐接枝聚乙烯对氢氧化铝进行表面处理,可以改善体系混炼过程的熔体流动性,增强力学性能,但氧指数无显著变化；SEM测试显示氢氧化铝在聚乙烯基相中达到了更好的分散。     

Citizens of the Future: Beyond Normative Conditions through the Emergence of Desirable Collective Properties

In this paper I explore the influence of an organisation's structure, such as that of the National Education System, in the emergence of desirable social properties. In this case the concern is schools with adequate performance. It is assumed that there is a circular causality between structure and the social results of schools. I highlight some of the structural requirements to have justice, sense of belonging, trust, honesty and cooperation as emerging properties of these schools, beyond normative statements. These are requirements for effective citizenship. In order to study this, it is necessary to observe the structures that constitute collectives into organisations. Central to this paper is a case study that I carried out at Millfield Primary School in the U.K., which focused on the observation of citizenship as a dynamic process permanently being constructed. This case went beyond the normative understanding of citizenship as established in the new school curriculum to be implemented from September 2002. I take the view that the aim of citizenship is to build up a community in which one is constituted as a citizen. For that purpose we need enabling people to build up their own communities. My conclusion from this case study suggests that current educational methodologies aim at teaching a "model of" citizenship rather than at providing the necessary tools to think about and create suitable spaces "for" citizenship. The case study shows that it is necessary to reinforce in schools practical methods to create membership and respect for others.

17-4PH马氏体沉淀硬化不锈钢锻造开裂问题的解决措施

17-4PH马氏体沉淀硬化不锈钢材料的用途越来越广,不过其产品在锻造过程中表层开裂特别严重。钢锭是通过电渣重熔冶炼出来的,无重熔时暂留缺陷。钢锭通过机床加工两端和车光外径,在鐓粗过程、拔长过程、压下过程都会产生严重开裂事故,导致生产不能正常进行。为了解决这种情况,在本文的分析研究中,对其原因进行深入分析,并提出相关解决措施。
