In this paper an improved Delphi method based on Cloud model is proposed in order to deal with the fuzziness and uncertainty in experts' subjective judgments. The proposed Cloud Delphi Method (CDM) describes experts' opinions by Cloud model and we aggregate the experts' Cloud opinions by synthetic algorithm and weighted average algorithm. Another key point of CDM is to stabilize and accommodate the individual fuzzy estimates by the defined stability rules rather than having to force them to converge, or reduce. The Cloud opinions and aggregation results can be exhibited in a graphically way leading experts to judge intuitively and it can decrease the number of repetitive surveys and/or interviews. Moreover, it is more scientific and easier to represent experts' opinion base on Cloud model which can combine fuzziness and uncertainty well. A numerical example is examined to demonstrate applicability and implementation process of CDM. Keywords: Decision making; Cloud Delphi method; Cloud model; fuzzy; uncertai nty 全文链接
《A user centric service-oriented modeling approach》，Ding-Yuan Cheng, Kuo-Ming Chao, Chi-Chun Lo, Chen-Fang Tsai World Wide Web (2011)， Springe Abstract With rapid development of service-oriented architecture and cloud computing, web services have been widely employed on the Internet. Quality of Service (QoS) is a very important criterion for service consumers to measure and select services. The selection of web services with respect to non-functional QoS criteria can be considered as a Multiple Criteria Decision Making (MCDM) problem when multiple consumers need to share a number of services. This paper describes a new user centric service-oriented modeling approach which is featured by integrating fuzzy Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) and Service Component Architecture (SCA) to facilitate web service selection and composition and to effectively satisfy a group of service consumers’ subjective requirements and preferences in the dynamic environment. The main contribution of this method is able to translate a group of users’ fuzzy requirements to services as well as model different levels of hardware and software as services to meet the requirements. We also design a simulated environment that includes 8*8 LED matrix on a circuit board that corresponds to an office with different appliances to demonstrate the dynamic service selection and binding. The simulation is used to assess the computational efficiency of the fuzzy TOPSIS method and the effectiveness of the proposed system.

For the first time, the Chinese government has revoked a major technology award because the prize-winning work turned out to be fraudulent. Bloggers on a popular science site, ScienceNet.cn, are hailing the decision as a signal that the government is getting serious about cracking down on academic misconduct in China. China's National Office for Science and Technology Awards announced this month that investigations have confirmed allegations of fraud in an award-winning project that won second prize in a 2005 competition. The project, which involved nine researchers under the leadership of Li Liansheng, formerly of Xi'an Jiaotong University (XJTU), claimed to have developed key technologies for a scroll compressor, useful for air conditioning, and to have successfully commercialized the product. The government has withdrawn the award certificates for this work and demanded the return of the prize money, roughly $12,000. The government's decision is the latest blow to Li, who was fired by XJTU in March after being criticized by peers. Chen Yongjiang, an 83-year-old retired XJTU professor, and five colleagues accused Li of misconduct several years ago and sought to have the university reprimand him. According to Chinese news reports, the professors said university officials first tried to suppress their complaints but failed. The professors opened a blog under Chen's name on ScienceNet.cn in March 2009, after which the Chinese mainstream media picked up their cause. On 20 March 2010, Chinese Central Television looked into the controversy in a prime-time show, a 30-minute program called Focused Interviews that provides in-depth reporting and commentary on current events. XJTU fired Li the day after the program was aired. When Chinese reporters sought to interview Li after the award was revoked, he responded that he did not wish to comment. Fang Shimin, the self-styled watchdog of academic corruption in China said Li is a small fry among those alleged to have committed research fraud: "It's much harder to punish those with higher ranks," Fang told Southern Daily newspaper. 转载:http://news.sciencemag.org/scienceinsider/2011/02/chinese-technology-prize-revoked.html
妹子的decision letter回来了，竟然是要revision，可比我想象得好多了。真为她骄傲。 我感叹，不同的导师命运不同。俺家妹子的论文导师定了题目，什么东西都是自己吭哧吭哧地写，从写文章（in English)到投稿，基本小丫头是主力，导师只负责简单修改。可怜小丫头连cover letter是啥都不知道。我因为严守“你的论文应该你导师负责”的原则，一点忙都不肯帮她（主要是自己忙死），还打击她估计人家editor都不送出去审。没想到送出去两个多月，前天小丫头兴奋地跟我说，decision回来了，让修改。I am so proud of you! :) 小丫头可以自己写全英文的论文，这是很多清华一年级硕士生都做不到的。 再感叹一下，妹子的学校好歹也是211、985的北京地方名校（嘿嘿），硕士生却连个生活费都不发，一年导师给发个几百块钱的过节费，小丫头乐得屁颠屁颠的。而且小丫头还一口跟我咬定她们导师是难得的好老板，害的我嫉妒羡慕恨的不行，看来我以后也要学着放养了，哈哈
Dear Prof Peiyang, Evidence 2010 Transforming Healthcare, 1-2 November, 2010 London will bring together the various groups of the healthcare chain for cost-effective change, and to transform healthcare. 3 conference streams will provide a more integrated approach to the development of evidence-based healthcare and allow you to customise the programme according to your learning needs. Evidence Implementation Transforming Healthcare Click for the full Conference programme Key speakers include Ben Goldacre, Victor Montori, Paul Glasziou, Jim Easton, Sir Iain Chalmers and Sir Muir Gray. There are limited places available and the last CEBM conference sold out early, so book now to secure your place. We look forward to seeing you at Evidence 2010.
