information systems MANAGEMENT 2005年第4期22卷 43-55页

作者： Aaltonen, A Huuskonen, P Lehikoinen, J Works as a research program manager in Nokia Research Center. His current research focuses on mobile user interface concept and design as well as information visualization. Principal scientist with Nokia Research Center. Dr. Huuskonen's research interests include context awareness ubiquitous computing and knowledge-based systems. Acts as a principal scientist in Nokia Research Center. Dr. Lehikoinen's current research interests include human– computer interaction especially from the interaction and collaboration point of view and mobile augmented reality.

This article reviews the ongoing evolution of context awareness technologies in mobile devices using personal media as an illustrative application domain. Augmented with metadata, files containing personal media can include significant information about the contexts they describe. The article discusses personal media applications from two different perspectives: (1) through an example that describes the use of context data in a personal media diary application, and (2) with a classification of context architectures that includes three classes of context-aware mobile systems (inbound, shared, and network assisted). These systems are classified on the basis of such factors as their architecture, data flow types, privacy, and interoperability requirements. The article concludes by discussing implications for research and practice.

Cognitive radios, MIMO antennas, wireless mesh networks, self-configuration support, seamless and context mobility, mobile user agents, and mobiquitous, multimedia, always-on, location-based communication services, are just some of the terms that have become part of the emerging lexicon to describe the future wireless communication technology landscape for 4G and beyond. From the mobile device, airlinks, and internet access network to the applications and services that next generation mobile service providers are to support, only one point seems to enjoy global consensus: we have barely begun to scratch the surface in creating the networks to serve the communication needs of a future media-hungry world equipped with an ever-increasing number of wireless devices. At the core of all this anticipated growth lies the following question: what technology enablers or application drivers will provide the incentive to fuel all these innovations? This panel will elicit thought-provoking discussions on the evolution and/or revolution of wireless and mobile networking technology. Technology experts from academia and industry will share their perspectives on which are the key drivers that are likely to support the introduction of innovations and propose a technology roadmap highlighting research, industrial, and political challenges to be addressed. Those who can predict where the next big bang is likely to occur will have arunning start in the race to untether the communication services of future generations.

A Moment-Based Method for Large-Scale Generalized Eigenvalue Problems

引用

Applied Numerical Analysis & Computational Mathematics 2004年第2期1卷

作者： Tetsuya Sakurai Hiroto Tadano Yuichi Inadomi Umpei Nagashima Department of Computer Science University of Tsukuba Tsukuba 305-8573 Japan Core Research for Evolutional Science and Technology Japan (CREST) Doctoral Program of Systems and Information Engineering University of Tsukuba Tsukuba 305-8573 Japan Grid Technology Research Center National Institute of Advanced Industrial Science and Technology Tsukuba 305-8568 Japan

In this paper we consider a method for finding several eigenvalues and corresponding eigenvectors of large-scale generalized eigenvalue problems. In this method, a small matrix pencil that has only the desired eigenvalues is derived using complex moments obtained via numerical integration. Since the process to derive the moments can be performed in parallel and we do not need to exchange data between processes, the presented method is suitable for master-worker programming models. We have implemented and tested the proposed method in a grid RPC (remote procedure call) system. Numerical examples illustrate the properties of our approach. (© 2004 WILEY-VCH Verlag GmbH & Co.

Journal of Labor and Society 2004年第2期7卷

作者： Joan Greenbaum David Kotelchuck JOAN GREENBAUM is professor of computer information systems at LaGuardia Community College of the City University of New York (CUNY) and she is on the faculty in environmental psychology of the Graduate Center (CUNY). Greenbaum and David Kotelchuck are co‐chairs of Health and Safety for the Professional Staff Congress of CUNY (Local 2334 AFT). DAVID KOTELCHUCK is associate professor in the Urban Public Health Program at Hunter College (CUNY) and is director of Hunter College Center for Occupational and Environmental Health. He has been a member of the board of directors of the New York Committee for Occupational Safety and Health for many years.

For more than a century the industrial sector was center stage for safety and health struggles. While industrial issues are still vital, the scope of conflict has broadened to include white‐collar and service occupations, which now constitute the overwhelming majority of American workers. In many workplaces, the air quality may be as poor as–or worse than–it is outdoors. Unions are becoming increasingly aware of such issues, and the Health and Safety Committee of the Professional Staff Congress of the City University of New York is taking an innovative approach to the problem with its “Got Air?” campaign.

Gender Differences in the Perceptions of Online Privacy

Gender Differences in the Perceptions of Online Privacy

Decision Sciences Institute 2002 Proceedings

作者： Chen, Kuanchin Rea Jr., Alan I. Computer Information Systems Program Haworth College of Business Western Michigan University Kalamazoo MI 49008

Protecting personal information while Web surfing has become an online battle. This is especially the case with transactions involving a modicum of trust to be successfully completed. E- businesses argue that they need personal information so they can create viable data to tailor user interactions and provide targeted marketing. However, users are wary of providing personal information because of a lack of trust in E-businesses' personal information policies and practices. E-businesses have attempted various techniques to mitigate user apprehension and build a relationship base in B2C transactions in order to facilitate the sharing of personal information. Some have been successful. This paper discusses survey results that suggest a relationship between gender and how users control personal information. The findings suggest that E-businesses should reconsider information policies to increase information exchanges.

Proceedings of the First International Conference on information Technology and Applications (ICITA 2002)

作者： Smith, M. Department of Information Systems Anglia Polytechnic University United Kingdom Computer Networks Cisco Networking Academy Program APU

ISBN: (纸本)1864671149

This paper describes a project to investigate the effectiveness of embedding the Cisco Networking Academy program, a web-based curriculum, to a particular subject area of computer networks, and considers whether the approach could be usefully expanded to include larger sections of the information systems subject domain. The benefits and pitfalls of the approach are identified and the educational concerns of the inclusion of industry certified courses are addressed. Methodology included student questionnaires, on-line course feedback, and interviews from which a set of conclusions was derived. Fundamental changes in the student experience were identified. While the students had extensively used the WWW for information retrieval and browsing, a number of students had difficulty in adapting to web-based learning. A common problem was one of acquiring knowledge via a computer display rather than traditional textbooks. Students preferred on-line assessment, particularly the instant feedback of their grade and the perceived impartiality of marking;and they welcomed the use of structured practical sessions to consolidate their theoretical knowledge. Lecturers liked the change in their role from teacher to mentor, but expressed concern on over reliance of multiple-choice questions without written assessment in higher levels of learning.

Marketing Education Review 2002年第1期12卷 1-10页

作者： Williamson, Ken williakc@jmu.edu Brookshire, Robert G. brrokdrg@jmu.edu Wright, Newell D. wrightnd@jmu.edu (University of Tennessee Knoxville) Professor of e-business and Director of the B.B.A. Core Curriculum at James Madison University (Emory University) Professor and Director of the Computer Information Systems and Operations Management Program at James Madison University

An assortment of courses, minors, majors, degree and certificate programs, and 'centers' addressing internet marketing, e-commerce, and e-business is emanating from colleges and universities globally. There's no debate regarding the appropriateness of incorporating into curricula 'digital' content, nor does there seem to be contention regarding relevant topical coverage. Whether to integrate digital content into existing course work or create a dedicated curriculum is a 'hot button.' This article describes the authors' experience in addressing these matters as they work to implement a B.S. degree program in e-business at their state supported institution. [ABSTRACT FROM AUTHOR]
