81岁的乔治·索罗斯即将退隐金融江湖。7月27日,索罗斯宣布将不再为外部投资者理财,返还10亿美元的客户资金,从今往后将专心经营自己家族的投资业务。无疑,这意味着"索罗斯时代"正在走向尾声,他40年的对冲基金经理人生涯正在宣告结束。不过,现在能够接替索罗斯江湖地位的对冲基金经理显然还未出现。在这样的经济大时代,唯一可与他比肩的基金经理只有比他晚18天出生的沃伦·巴菲特。索罗斯身退,不代表他将远离金融市场,相反,索罗斯依然具有"一言九鼎"的能 相似文献

Media Impact usually focuses on the practical impact of multimedia research on IT business. Yet given the pervasiveness of multimedia technology in our everyday life, a thorough reflection on the impact of multimedia progress on education and, in particular, multimedia education is overdue. Multimedia teachers at the 2007 ACM Multimedia conference engaged in a panel discussion on the current state and future of multimedia education. In this issue's,Wolfgang Hürst of Utrecht University and his colleagues Gerald Friedland of the International Computer Science Institute, Berkeley, and Lars Knipping of Berlin University of Technology use this panel as an opportunity to argue the need for a dedicated multimedia curriculum in computer science education. 相似文献

Though common law declares the safety of the people as the supreme law and guarantees to every individual the right of personal safety, courts cannot protect individuals from product-caused injuries because of inherent shortcomings of the judicial process. Scientific and technological changes take place on a predetermined time scale but ethics and human values do not develop in the same manner. The adversary system of adjudication of private disputes cannot promote a contextual approach to technology assessment whereby goal-oriented policy can be made by courts. 相似文献

Wirelessness and radio technologies have been at the heart of many disruptive businesses and activities. This paper argues that this trend will continue as new research topics and novel ways to use existing techniques have an impact on both business and society. It discusses the fundamental issues of wireless and mobility, and looks beyond today's business environment to highlight potential future disruption. Some (potential) wireless disrupters are examined and the road to 3G cellular radio is discussed. Wirelessness has been coined to describe the spread of radio and mobile technology. The paper further discusses the way more and more people and artefacts will be networked wirelessly as the Internet moves in new directions and generates further disruption in its wake. 相似文献

Informational content of linear macromolecules (DNA, RNA, and proteins) is analyzed by the method of digital signal processing. Each element (amino acid or nucleotide) of macromolecules is represented by the corresponding value of electron-ion interaction potential. This numerical representation of the primary structure of macromolecules is subjected to digital signal processing in order to extract the information corresponding to biological function. It is shown that the multiple cross spectrum of functionally related sequences exhibits significant peak frequencies. In the case of functionally unrelated sequences such peaks were not found. Peak frequencies are different for different biological functions. Based on this, we conjecture that the peak frequencies in the multiple cross spectrum of sequences with the same boilogical function are related to this biological function. 相似文献
