Now thoroughly streamlined and revised, PRINCIPLES OF INFORMATION SYSTEMS, Ninth Edition, retains the overall vision and framework that made the previous editions so popular while eliminating outdated topics and updating information, examples, and case studies. In just 600 pages, accomplished authors Ralph Stair and George Reynolds cover IS principles and their real-world applications using timely, current business examples and hands-on activities. Regardless of their majors, students can use this book to understand and practice IS principles so they can function more effectively as workers, managers, decision makers, and organizational leaders. Important Notice: Media content referenced within the product description or the product text may not be available in the ebook version.

Fuzzy logic and continuous classification methods are presented as methods for linking the two spatial paradigms.

Equipping you with a solid understanding of the core principles of IS and how it is practiced, the brief FUNDAMENTALS OF INFORMATION SYSTEMS, 8E covers the latest developments from the field and their impact on the rapidly changing role of today's IS professional. A concise nine chapters, this streamlined book includes expansive coverage of mobile solutions, energy and environmental concerns, cloud computing, IS careers, virtual communities, global IS work solutions, and social networking. You learn firsthand how information systems can increase profits and reduce costs as you explore new information on e-commerce and enterprise systems, artificial intelligence, virtual reality, green computing, and other issues reshaping the industry. The book also introduces the challenges and risks of computer crimes, hacking, and cyberterrorism. A long-running example illustrates how technology was used in the design, development, and production of this book. No matter where your career path may lead, FUNDAMENTALS OF INFORMATION SYSTEMS, 8E can help you maximize your success as an employee, a decision maker, and a business leader.

The real threat to information system security comes from people, not computers. That's why students need to understand both the technical implementation of security controls, as well as the softer human behavioral and managerial factors that contribute to the theft and sabotage proprietary data. Addressing both the technical and human side of IS security, Dhillon's Princliples of Information Systems Security: Texts and Cases equips managers (and those training to be managers) with an understanding of a broad range issues related to information system security management, and specific tools and techniques to support this managerial orientation. Coverage goes well beyond the technical aspects of information system security to address formal controls (the rules and procedures that need to be established for bringing about success of technical controls), as well as informal controls that deal with the normative structures that exist within organizations.

The late 20th century has witnessed increasing crises in the world's marine fisheries. A causal analysis of these reveals that a common element are various manifestations of spatial inequity. This most frequently includes the inequity of access rights to the resource, but factors such as variations in resource depletion, spatio-temporal variations in stock recruitment, the imposition of regulatory zoning, destruction of marine ecosystems and the siting of mariculture facilities are other examples. To resolve some of these problems, management practices must be improved. As has been shown in other fields where spatially related problems occur, there is now a promising tool, Geographical Information Systems (GIS), which, combined with other analytical tools and models, could allow for improved spatial management. GIS are basically integrated computer based systems which allow for the input of digital geo-referenced data to produce maps plus other textual, graphical and tabular output. The essential usefulness of GIS however, lies in its ability to manipulate data in a large number of ways and to perform various analytical functions so as to produce output which makes for more efficient decision making.As with many computer based systems, the key to GIS success lies in the acquisition of suitable data. The various means by which both primary and secondary data can be located, gathered, accessed and stored are described.
