Identification of near surface events using athermal phonon signals in low temperature Ge bolometers for the EDELWEISS experiment

We present a study of a 100 g low temperature Ge detector, allowing identification of surface events down to the energy threshold. The bolometer is fitted with segmented electrodes and two NbSi Anderson insulator thermometric layers. Analysis of the athermal signals amplitudes allows us to identify and reject all events occurring in the first millimeter under the electrodes.     

Children's Ratings of the Stressfulness of Experiences.

To ascertain if children assess experiences in terms of stress and if their perceptions generally agree with those of adults, fourth, fifth, and sixth graders rated 20 life events on a 7-point scale. The scale values ranged from 1.27 for the least upsetting event (the arrival of a new sibling) to 6.90 for the most upsetting event (the loss of a parent). Overall, there were no statistically significant differences associated with grade, sex, or personal experience. Children were found to make distinguishing judgments of the perceived Stressfulness that often differed from those of professionals. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The unity of psychology.

An analysis of contemporary psychology reveals the existence of three distinct subject matters: behavior, neurophysiological events, and phenomenal experience. To unify psychology requires reducing two of the subject-matter areas to the theoretical principles of the third. Whether one subject matter can be reduced to another (e.g., behavior to neurophysiology) depends upon the formalization of the two theories involving the different subject matters and the demonstration that one formulation can explain the other. Explanation can be examined within two different frameworks, epistemological and psychological. Epistemologically, explanation occurs when a phenomenon is deduced from a set of theoretical principles. Psychologically an event is explained when it can be intuitively comprehended; made sensible in terms of one's own phenomenal experience. A unified psychology does not, and may never, exist. Whether a unity can potentially be achieved depends on the acceptance of a common criterion of explanation. Without a common conception psychology will inevitably be split into separate and distinct disciplines. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

"Explorations in Ecological Psychology": Erratum.

Reports an error in the original article by Roger G. Barker (American Psychologist, 1965, 20, 1-14). The captions for Figures 1 and 2 on pages 2 and 3, respectively, are correct and follow text, but the figures have been interchanged. (The following abstract of this article originally appeared in record 1965-08912-001.) The "great diversity of coupling between psychologists and psychological phenomena can be divided into 2 types which produce data of crucially different significance for the science of psychology." (1) Psychologists as Transducers--T Data: The psychologist transforms data and in effect is a translating machine. (2) Psychologists as Operators--O Data: The psychologist "achieves control which allows him to focus upon segments and processes of particular concern to him, via data that refer to events which he, in part, contrives." Psychologists "as operators and as transducers are not analogous, and . . . the data they produce have fundamentally different uses within science. A central problem of our science is the relation between ecological events (the distal stimuli) at the origin of E-O-E [environment-organism-environment] arcs and the succeeding events along these arcs." There "are a number of reasons for avoiding the role of transducer in psychological research . . . . The skills and personality attributes required of a successful transducer are different from those of a successful operator . . . . The techniques of the transducer are in many respects more difficult than those of the operator." (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

60年的追问：新中国建筑60年的足迹：“建筑中国六十年”系列丛书的事件与评论概说

回溯新中国建筑设计及建筑学理论研究60年的历程,既经历了创建、发展和辉煌,也经历了顿挫、困境与危机。＂建筑中国60年＂系列丛书从策划、编撰到出版的两年间是《建筑创作》杂志社团队不懈追求、理清历史史实、揭示事件内涵、把握作品评析要点的过程。为此本丛书力诫当下文化的＂浮躁＂病症,每一位作者力求用独特而深刻的历史批判视点,在展示中国建筑60年学术成就及优秀作品的同时,还坚守文化态度和积极探索真理的精神,努力反映出新中国一代代建筑学人们求真务实的学术品质。我以为＂建筑中国60年＂系列丛书的宗旨：要让新中国60年建筑的经典作品不仅仅真正成为一种思想和精神财富,更要引发出一系列真切的反省及总结机制,本丛书的＂建筑中国＂一词凸显新中国大厦奠基与新中国建筑作品建设过程这双重含义,前者具有宏观精神,后者更体现扎实的工程意义。作为一部志向于以建筑的名义向新中国60年华诞致敬的大型系列出版物,它已不再是一套具有某些个人情绪的建筑师随笔类＂小书＂,而是集中反映＂建筑中国60年＂历程中的记忆、作品、语言、文字、图片等精神财富的＂大书＂,从中不仅能读到建筑随时代变迁的发展史,更能成为珍贵的建筑设计学在理念与信息上的＂教科书＂,因为其中闪现着一代代建筑师在艰难中奋进且不无坎坷的身影,从此种意义上讲＂建筑中国60年＂系列就是希望用＂全集＂呈现60载中国建筑的文化创造。     

The Reverse Side of the Medal: About the 2010 FIFA World Cup and the Beautification of the N2 in Cape Town

This paper aims to show the reverse side of the (football) medal. The N2 gateway project in Cape Town is presented, by government and media, as a ‘flagship’ project of the new Breaking New Ground strategy, to fight the housing backlog of 400,000 houses in the city. But I want to argue that the fast-tracking of the project has to be understood as a beautification strategy to prepare the city for 2010. Massive slum eradication and the construction of ‘beautiful formal housing opportunities’ between the airport and the mother city are becoming a painful reminder of the forced removals under the apartheid regime.

用于间歇性电源高渗透电网规划的安全性评估方法

讨论了电力系统稳定性与安全性的从属关系,指出电网静态安全约束、暂态稳定约束和全过程安全评估宜分别在电网规划的不同步骤中考虑,提出了间歇性电源高渗透电网规划方案安全性评估流程。指出电力系统连锁反应事件部分过程具有开放的复杂巨系统的一些特性,其中一部分过程在仿真中难以准确模拟,需进行简化处理,而另一部分过程的前后事件之间具有强因果关系,这部分过程可采用改进的仿真软件进行模拟。提出了计及故障前发电系统状态的电网全过程风险评估计算方法,使用该方法,可将稳定设施费用和停电风险损失计入电网规划方案的综合年费用中,对方案进行安全性和经济性综合比较选择。     

东北电网混杂自动电压控制的研究

针对中国东北500kV电网的实际运行和调度情况,将混杂控制系统引入电力系统的电压控制,提出了东北电网混杂自动电压控制(HAVC)方案,建立了混杂分层电压控制模型,采用离散事件作为驱动主体,并可以实现复合指标调控。该控制方案可以提高东北电网的电压控制水平,增强电网抗扰动能力,改善电压稳定性,合理分配无功,减少网络损耗;并且由于系统控制目标分配至各控制层,通过离散事件来驱动控制,可降低优化问题的求解难度,提高运算效率,并能有效地利用现有技术条件,因此可实现性较好。计算机仿真研究证明了所提出和设计的控制系统、策略和方法的有效性。
