Classical meets modern in the IDEA protocol for structured expert judgement

Expert judgement is pervasive in all forms of risk analysis, yet the development of tools to deal with such judgements in a repeatable and transparent fashion is relatively recent. This work outlines new findings related to an approach to expert elicitation termed the IDEA protocol. IDEA combines psychologically robust interactions among experts with mathematical aggregation of individual estimates. In particular, this research explores whether communication among experts adversely effects the reliability of group estimates. Using data from estimates of the outcomes of geopolitical events, we find that loss of independence is relatively modest and it is compensated by improvements in group accuracy.     

Strong Nash equilibrium in games with common and complementary local utilities

A rather general class of strategic games is described where the coalitional improvements are acyclic and hence strong Nash equilibria exist: The players derive their utilities from the use of certain facilities; all players using a facility extract the same amount of local utility therefrom, which amount depends both on the set of users and on their actions, and is decreasing in the set of users; the ultimate utility of each player is the minimum of the local utilities at all relevant facilities. Two important subclasses are “games with structured utilities,” basic properties of which were discovered in 1970s and 1980s, and “bottleneck congestion games,” which attracted researchers’ attention quite recently. The former games are representative in the sense that every game from the whole class is isomorphic to one of them. The necessity of the minimum aggregation for the existence of strong Nash equilibria, actually, just Pareto optimal Nash equilibria, in all games of this type is established.     

初探历史性与现代性在路易斯·康作品中的交汇

路易斯·康作为20世纪下半叶世界最具影响力的建筑师之一,因其作品风格与创作思想的独特而受到众多建筑师的喜爱和追捧,特别在第三世界,其名声完全可以和柯布相媲美。通过深入的研究,不难发现康的作品正是通过对历史性和现代性的交汇而产生的,康通过其不平凡的建筑生涯形成了自己对建筑历史性的独特观点以及表达方式。     

严查行贿犯罪之实体进路

行贿直接诱发受贿．是腐败产生的温床,严查行贿犯罪是当前我国遏制腐败的必然要求。从实体法上解决查处行贿犯罪面临的“瓶颈”问题是刑法本身的社会性、刑事程序的僵化性、配套法律的欠缺性和国际条约的普适性之必然选择。为此,我们应该围绕严查的标准和需求,检视现行实体法存在的诸多不足,在此基础上,从罪与刑两个方面共同着力,既要严密法网,扩大行为犯罪化,加大追诉力度,又要疏缓刑罚,实现犯罪轻刑化,增加侦破几率．以此切实达到严查行贿犯罪之目的。

点光源追踪系统设计

旨在设计一个模拟强点光源追踪装置,以提高光源的利用率。装置由模拟强光源和光源追踪2部分构成。模拟强光源装置采用TI公司的LM317组成可调恒流源装置控制1W高亮度LED光源,并且使用电阻分流和MSP430f147内部ADC采样数显。追踪装置采用ATmel公司的ATmega16高性能AVR单片机作为主控芯片,将采集到的信号进行综合判别和处理,然后控制舵机实现对光源的跟踪,并可实现手动校准。

偏光显微镜法在空气粉尘中石棉纤维鉴别中的应用

本文采用偏光显微镜法鉴别空气粉尘中的微量石棉纤维。经滤膜收集的粉尘样品通过高温灰化及酸洗过程去除大部分干扰物质,经乙醇分散后均匀沉积在玻璃片上,滴加具有固定折射率的浸油制成试片。在正交偏光系统下观察到粉体中存在纤维状颗粒,且纤维呈现四次平行消光特性,比对6种常见石棉的偏光显微镜图,综合分析试样粉尘的光学性质,推断样品中含有温石棉。
