A CALCULUS FOR SERVICES INNOVATION

引用

Journal of Systems Science and Systems Engineering 2007年第2期16卷 129-165页

作者： james M. TIEN daniel BERG Department of Decision Sciences and Engineering Systems Rensselaer Polytechnic Institute Troy New York USA

Innovation in the services area - especially in the electronic services （e-services） domain - can be systematically developed by first considering the strategic drivers and foci, then the tactical principles and enablers, and finally the operational decision attributes, all of which constitute a process or calculus of services innovation. More specifically, there are four customer drivers （i.e., collaboration, customization, integration and adaptation）, three business foci （i.e., creation-focused, solution-focused and competition-focused）, six business principles （i.e., reconstruct market boundaries, focus on the big picture not numbers, reach beyond existing demand, get strategic sequence right, overcome organizational hurdles and build execution into strategy）, eight technical enablers （i.e., software algorithms, automation, telecommunication, collaboration, standardization, customization, organization, and globalization）, and six attributes of decision informatics （i.e., decision-driven, information-based, real-time, continuously-adaptive, customer-centric and computationally-intensive）. It should be noted that the four customer drivers are all directed at empowering the individual - that is, at recognizing that the individual can, respectively, contribute in a collaborative situation, receive customized or personalized attention, access an integrated system or process, and obtain adaptive real-time or just-in-time input. The developed process or calculus serves to identify the potential white spaces or blue oceans for innovation. In addition to expanding on current innovations in services and related experiences, white spaces are identified for possible future innovations; they include those that can mitigate the unforeseen consequences or abuses of earlier innovations, safeguard our rights to privacy, protect us from the always-on, interconnected world, provide us with an authoritative search engine, and generate a GDP metric that can adequately measure the gro

ON SERVICES RESEARCH AND EDUCATION

引用

Journal of Systems Science and Systems Engineering 2006年第3期15卷 257-283页

作者： james M.TIEN daniel BERG Department of Decision Sciences and Engineering Systems Rensselaer Polytechnic Institute

The importance of the services sector can not be overstated; it employs 82.1 percent of the U. S. workforce and 69 percent of graduates from an example technological university. Yet, university research and education have not followed suit. Clearly, services research and education deserve our critical attention and support since services - and services innovation - serve as an indispensable engine for global economic growth. The theme of this paper is that we can and should build services research and education on what has occurred in manufacturing research （especially in regard to customization and intellectual property） and education; indeed, services and manufactured goods become indistinguishable as they are jointly co-produced in real-time. Fortunately, inasmuch as manufacturing concepts, methodologies and technologies have been developed and refined over a long period of time （i.e., since the 1800s）, the complementary set of concepts, methodologies and technologies for services are more obvious. However, while new technologies （e.g., the Internet） and globalization trends have served to enable, if not facilitate, services innovation, the same technologies （e.g., the Internet） and 21st Century realities （e.g., terrorism） are making services innovation a far more complex problem and, in fact, may be undermining previous innovations in both services and manufacturing. Finally, there is a need to define a ＂knowledge-adjusted＂ GDP metric that can more adequately measure the growing knowledge economy, one driven by intangible ideas and services innovation.

The Einstein-Scalar Field Constraints on Asymptotically Euclidean Manifolds

引用

Chinese Annals of Mathematics,Series B 2006年第1期27卷 31-52页

作者： Yvonne CHOQUET-BRUHAT james ISENBERG daniel POLLACK Dedicated to the memory of Shiing-Shen Chern

By using the conformal method, solutions of the Einstein-scalar ficld gravitational constraint equations are obtained. Handling scalar fields is a bit more challenging than handling matter fields such as fluids, Maxwell fields or Yang-Mills fields, because the scalar field introduces three extra terms into the Lichnerowicz equation, rather than just one. The proofs are constructive and allow for arbitrary dimension （〉 2） as well as low regularity initial data.
