Math On The Internet 1997 1998

Inhaltsangabe:Abstract: Electronic Commerce, once thought of as futuristic buzzwords, is becoming a commonly used term. International newspapers, magazines, and the electronic media mention at least some forecast or news related to this subject on a daily basis. Nevertheless, a look at the growing numbers of consulting companies, that offer a variety of services relating to Electronic Commerce reveals the immense uncertainty companies are experiencing about what exactly Electronic Commerce is, and how they can implement it. While it seems that the importance of this issue in the business environment is widely accepted in the US, a recent study from Andersen Consulting (Andersen, 1998) shows that among European senior executives only 19% regard Electronic Commerce as a serious competitive threat to their business. Furthermore, only 39% are taking steps today to incorporate Electronic Commerce into their current operational strategies. There is a number of factors contributing to the "wait-and-see" attitude taken by executives and consumers as well. Executives tend to view the rise of Electronic Commerce as an external business environment issue, while consumers are concerned about security issues. These are still common views in the US. In European countries, a cultural problem stemming from a slowly changing and stable business environment adds to that problem. Fear of failing by trying a new approach, in most cases, overshadows the willingness to take new risks. Nevertheless, the uncertainty about the changes implied by Electronic Commerce are far-reaching and can be found in any country. With the increasing importance of the Internet, the business environment, as well as other areas in society, is about to fundamentally change. Old paradigms are no longer working in the evolving new business world, sometimes called digital economy. Electronic Commerce is the keyword that tries to capture the new paradigms which are not even clear yet. The only thing that is reliable and predictable about Electronic Commerce and the new economy, is change. Never before was it more important to be flexible and willing to take risks by trying new approaches. As businesses like to operate in a predictable environment where planning the future is easy, it becomes very difficult to adapt to the pace of change. Not only do businesses need new strategies, they also need to constantly reinvent themselves. Businesses need to realize, that it becomes necessary to accept [...]

This thorough update to Benjamin Compaine's original 1979 benchmark and 1982 revisit of media ownership tackles the question of media ownership, providing a detailed examination of the current state of the media industry. Retaining the wealth of data of the earlier volumes, Compaine and his co-author Douglas Gomery chronicle the myriad changes in the media industry and the factors contributing to these changes. They also examine how the media industry is being reshaped by technological forces in all segments, as well as by social and cultural reactions to these forces. This third edition of Who Owns the Media? has been reorganized and expanded, reflecting the evolution of the media industry structure. Looking beyond conventional wisdom and expectations, Compaine and Gomery examine the characteristics of competition in the media marketplace, present alternative positions on the meanings of concentration, and ultimately urge readers to draw their own conclusions on an issue that is neither black nor white. Appropriate for media practitioners and sociologists, historians, and economists studying mass media, this volume can also be used for advanced courses in broadcasting, journalism, mass communication, telecommunications, and media education. As a new benchmark for the current state of media ownership, it is invaluable to anyone needing to understand who controls the media and thus the information and entertainment messages received by media consumers.

The National Science Education Standards set broad content goals for teaching grades K-12. For science teaching programs to achieve these goalsâ€"indeed, for science teaching to be most effectiveâ€"teachers and students need textbooks, lab kits, videos, and other materials that are clear, accurate, and help students achieve the goals set by the standards. Selecting Instructional Materials provides a rigorously field-tested procedure to help education decisionmakers evaluate and choose materials for the science classroom. The recommended procedure is unique, adaptable to local needs, and realistic given the time and money limitations typical to school districts. This volume includes a guide outlining the entire process for school district facilitators, and provides review instruments for each step. It critically reviews the current selection process for science teaching materialsâ€"in the 20 states where the state board of education sets forth a recommended list and in the 30 states where materials are selected entirely by local decisionmakers. Selecting Instructional Materials explores how purchasing decisions are influenced by parent attitudes, political considerations, and the marketing skills of those who produce and sell science teaching materials. It will be indispensable to state and local education decisionmakers, science program administrators and teachers, and science education advocates.
