A resilience assessment method for urban water systems

Infrastructure planning for Urban Water Systems (UWSs) is challenged by, inter alia, increasing uncertainty in both demand and availability of water and aging infrastructure, and this is already impacting the climate-proofing of cities. In this context, the idea of resilience has been gradually embraced by the water sector, but the term itself is not yet universally defined, nor operationalised. Here, we propose a methodology to assess the resilience of a UWS, defining it as the degree to which the UWS continues to perform under increasing stress. A resilience assessment method is then proposed as a ‘stress-test’ of UWS configurations, under increasingly more stressful scenarios. We then demonstrate a toolbox assembled for the proposed analysis using, as a proof of concept, a semi-synthetic case study. Results are promising, suggesting that the approach could assist in the uptake and evolution of resilience thinking in strategic water infrastructure decision making, leading to water-wiser cities.     

未来自管理互联网的结构和机制

文章介绍了由欧盟第七框架（FP7）项目EFIPSANS提出的具有自治属性的未来自管理互联网的结构和机制。该结构将网络的功能分成决策、分发、发现及数据等4个平面。位于不同平面的决策单元和被管理实体及其他信息收集实体组成协议层、功能层、节点层及网络层等4个层次的控制环。决策单元及其相关的控制环和被管理的实体实现了网络对自身的管理和维护,大大减少用户和管理员对网络的干预,从而降低网络的运营成本,提高终端用户的体验。目前欧洲电信标准组织（ETSI）成立了一个新的工业标准研究组,正在进行自管理互联网相关的标准化工作。

The relationship of hope in the future and perceived school climate to school completion.

This study examined the impact of hope in the future and school climate as protective factors in school dropouts and graduates. Participants consisted of 97 students (males and females, aged 14-21 yrs) at risk for not completing school in an urban area. At-risk status was determined by student assignment to a continuation high school, a special placement for students who had had numerous infractions at regular high schools. Retrospectively, dropouts rated perceived school climate significantly lower than graduates, and graduates rated the importance of attending college significantly higher than dropouts. Dropouts and graduates who left school after the study was conducted did not report differences on the risk factors measured, nor did they differ on perceived school climate or the importance of attending college. However, hope in the future significantly predicted dropout versus graduate status for these participants. Results are discussed as describing differences in retrospective versus prospective reports, and as evidence of the utility of the risk/resilience paradigm in school completion research.

Turkish aggregate electricity demand: An outlook to 2020

This paper investigates the relationship between Turkish aggregate electricity consumption, GDP and electricity prices in order to forecast future Turkish aggregate electricity demand. To achieve this, an aggregate electricity demand function for Turkey is estimated by applying the structural time series technique to annual data over the period 1960 to 2008. The results suggest that GDP, electricity prices and a UEDT (Underlying Energy Demand Trend) are all important drivers of Turkish electricity demand. The estimated income and price elasticities are found to be 0.17 and −0.11 respectively with the estimated UEDT found to be generally upward sloping (electricity using) but at a generally decreasing rate. Based on the estimated equation, and different forecast assumptions, it is predicted that Turkish aggregate electricity demand will be somewhere between 259 TWh and 368 TWh in 2020.     

Technology, human, and society centred visions of the future of technology

In this article we look at the conceptions computing professionals have of the future. We studied these conceptions by analysing 31 essays on the future published in theCommunications of the ACM. We found the future was envisioned from three different perspectives: in addition to a technology centred perspective the authors also used human centred and society centred perspectives, but region centred and organisation centred perspectives were missing. I assume the visions of these individuals of future technology represent the culture of the computing field as they are published in one of the top computer science journals.     

沉淀历史的新景观——走进杭州小河直街历史文化街区

小河直街历史街区是杭州历史文化名城保护规划划定的历史地段之一。经历了漫长的年代,其损坏却日益严重起来。自从杭州对小河直街严重受损的房屋以及其建筑结构进行重建和修缮后,当时的历史元素等得到了保护,但"新形象"与河岸建筑及完整保留下来的民居建筑外观令人有种不协调之感。因此,在历史文化遗产的修复和保护热潮不断受到各界广泛关注之时,我们该怎样面对现在进行中的保护模式和未来的发展趋势,十分值得我们探讨和关注。     

Canadian counselling psychology: From defining moments to ways forward.

Counselling psychology in Canada is a distinct and vibrant professional area representing the contributions of many people and events within a unique context. This article elaborates a number of defining moments or actions that reveal the distinct nature of this professional area through a recursive and interactive process with the social context. A number of ways forward are proposed as specific professional developments, as well as the resolution of a number of substantive issues identified within the recently adopted definition of counselling psychology. Moving forward as a discipline and a practice will actualize the potential of counselling psychology as both world and life enhancing. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
