This book focuses on several issues in the essence of information systems and their development, as well as advanced utilization of new information technology. It includes both theoretical foundations and practical approaches for each topic and will prove useful both to scientists in the field of information system science and to practitioners in information systems development and use. Many of the topics treated here have not appeared in the literature, although they are becoming increasingly important in the development of information systems. Topics covered include: contingencies in IT decision making; intelligent executive information systems; dynamic performance evaluation of information systems; exception handling in information systems, metamethodology of information system development and mobile computing. The outstanding feature of the book is its specific mixture of subjects under one framework of thinking about information systems. A useful book to researchers and systems developers, the book can also form the basis of an advanced course in information systems development.
Arnold Hansen Director Marine Technology Centre Trondheim Norway Norwegian fisheries are presently facing serious problems, but also some promising challenges. Most important is the fact that nearly all the major fish stocks have been over-exploited, either by an overall too large fishing effort or a too large effort on wrong year-classes, resulting in stock-sizes reduced well below an economically optimum level or even nearly depleted. The atlanto-scandic herrings, for instance, has been below an exploitable level for several years. The recommended total allowable catch of Norwegian-Arctic cod for 1980 is 390,000 tons compared to more than 800,000 tons a few years ago. The Norwegian industr...
Sentiment analysis and opinion mining is the field of study that analyzes people's opinions, sentiments, evaluations, attitudes, and emotions from written language. It is one of the most active research areas in natural language processing and is also widely studied in data mining, Web mining, and text mining. In fact, this research has spread outside of computer science to the management sciences and social sciences due to its importance to business and society as a whole. The growing importance of sentiment analysis coincides with the growth of social media such as reviews, forum discussions, blogs, micro-blogs, Twitter, and social networks. For the first time in human history, we now have...
The NATO Advanced Research Institute on Search Theory and Appli cations was held at the Hotel Algarve in Praia Da Rocha, Portugal, from March 26 through March 30, 1979, and was sponsored by the NATO Special Programme Panel on Systems Science. There were forty-one participants representing a wide range of backgrounds and interests. The purpose of the institute was to bring together people working in search theory and applications with potential users of search techniques to stimulate the increased application of recent ly developed search technology to civilian problems such as search and rescue, mineral exploration, surveillance, and fishing. Con versely, it was felt that by exposing search ...
This Proceedings presents refereed versions of most of the papers presented at the NATO Advanced Research Institute on Homotopy Methods and Global Convergence held in Porto Cervo, Sardinia, June 3-6, 1981. This represents the fourth recent occurrence of an international conference addressing the common theme of fixed point computation. The first such conference, ti tled "Computing Fixed Points with Applications," was held in the Department of Mathematical Sciences at Clemson University, Clemson, South Carolina, June 26-28, 1974 and was sponsored by the Office of Naval Research and the Office of the Army Research Center. The second conference, "Symposium on Analysis and Computation of Fixed P...
In September 1980, the Special Programme Panel on Systems Sciences of the North Atlantic Treaty Organization (NATO) sponsored an Advanced Research Institute (ARI) on "Systems Analysis in Urban Policy-Making and Planning" which was held at New College, Univer sity of Oxford, from 21st to 27th September. This week-long meeting brought together 35 invited delegates from most countries of the NATO Alliance to discuss the impact which syst~ms analysis has had and is likely to have on urban affairs. The manuscript was submitted to the publisher in June of 1982. Although the goal of the ARI was to assess the impact of urban systems analysis as seen through the eyes of those closely involved in such work, the meeting also addressed opportunities for future research and development, and therefore in this book we have attempted to synthesize discussions at the meeting with this in mind. But before we describe the structure of this book, it is worth recounting in a little more detail the intentions and organi zation of the meeting, for this has had an important effect on the type of papers produced here, the way they have been written, and the issues they address.
The Advanced Research Institute (A.R. 1.) on "the efficiency of Manufacturing Systems" was held under the auspices of the NATO Special Programm~ Panel on Systems Science as a part of the NATO Science Committee's continuous effort to promote the advancement of science through international co-operation. Advanced Research Institutes are organised for the purpose of bringing together experts in a particular field of interest to identify and make known the present state of knowledge in that area and, through informed debate, to make recommendations for directions for future research that would benefit the community at large. To this end two kinds of contribution were obtained by invitation. There were those papers which were about the current state of work in the area of manufacturing systems and its organisation; in addition three theme papers were presented to provide a stimulus to the discussion in terms of ways of thinking, both about the area and about the kind of research needed.
The Advanced Research Institute (ARI) on "The Application of Systems Science to Energy Policy Planning" was held under the auspices of the NATO Special Programme Panel on Systems Science in collaboration with the National Center for Analysis of Energy Sys tems, Brookhaven National Laboratory, USA, as a part of the NATO Science Committee's continuous effort to promote the advancement of science through international cooperation. Advanced Research Institutes are sponsored by the NATO Science Committee for the purposes of bringing together senior scientists to seek consensus on an assessment of the present state of knowl edge on a specific topic and to make recommendations for future research d...
This volume is the proceedings of the conference entitled "Manpower Planning and Organization Design" which was held in Stresa, Italy, 20-24 June 1977. The Conference was sponsored by the NATO Scientific Affairs Division and organized jointly through the Special Programs Panels on Human Factors and on Systems Science. Two Conference Directors were appointed with overall responsibilities for the programme and for policy, and they were assisted in their tasks by a small advisory panel consisting of Professor A. Charnes (University of Texas), Professor W.W. Cooper (Carnegie Mellon University, now at Harvard University) and Dr. F.A. Heller (TavistQck Institute of Human Relations). Professor R. F...
