Open Systems Handbook, Second Edition provides an easy-to-read, thorough, and management-oriented explanation of the promises, dangers, and realities of open systems. This edition describes specific products and various open systems that have been updated to reflect the events of the mid-1990s. Emerging open technologies that either didn't exist in 1991 or were in their infancy, such as client/server middleware, are also covered. Topics include the definitions and history of open systems, open systems components, end user interaction points, and elements of open systems software. The general communications hardware, visual application development, models of integration, and advantages of open systems are likewise elaborated. This publication is a good reference for computing professionals and engineers working on open systems.

A call to action for school and community leaders to reframe educational institutions as open systems that are adaptable and responsive to the needs of students, families, and communities. Landon Mascareñaz and Doannie Tran propose that, even as events of this decade have exposed stress points in existing top-down, closed systems within education and other public institutions, they have also created prime opportunities to rethink and redesign those systems in ways that encourage civic participation and invigorate local democracy. In The Open System, Mascareñaz and Tran argue for a critical revitalization of public education centered in openness, an organization design concept in which an entity receives, considers, and acts on input from the community it serves. As they demonstrate, open education policy improves information flow, increasing opportunity, bolstering public trust, and making room for cocreation and coproduction driven by community partnerships and family engagement. Based on their groundbreaking work with educational coalitions such as the Kentucky Coalition for Advancing Education and Colorado’s Homegrown Talent Initiative, Mascareñaz and Tran introduce six key liberatory moves that can bring about open system transformation. They highlight real-life examples of the types of incremental, specific, and discrete projects that leaders can use to create openness in educational systems at the school, district, and state levels, providing a blueprint for changemaking.

This IBM® Redbooks® publication discusses IBM System Storage Open Systems Tape Encryption solutions. It specifically describes Tivoli Key Lifecycle Manager (TKLM) Version 2, which is a Java software program that manages keys enterprise-wide and provides encryption-enabled tape drives with keys for encryption and decryption. The book explains various methods of managing IBM tape encryption. These methods differ in where the encryption policies reside, where key management is performed, whether a key manager is required, and if required, how the tape drives communicate with it. The security and accessibility characteristics of encrypted data create considerations for clients which do not exist with storage devices that do not encrypt data. Encryption key material must be kept secure from disclosure or use by any agent that does not have authority to it; at the same time it must be accessible to any agent that has both the authority and need to use it at the time of need. This book is written for readers who need to understand and use the various methods of managing IBM tape encryption.

In this book the author develops a new approach to uncertainty in economics, which calls for a fundamental change in the methodology of economics. It provides a comprehensive overview and critical appraisal of the economic theory of uncertainty and shows that uncertainty was originally conceptualized both as an epistemic and an ontological problem. As a result of the economic professions’ attempt to become acknowledged as a science, the more problematic aspect of ontological uncertainty has been neglected and the subjective probability approach to uncertainty became dominant in economic theory. A careful analysis of ontological theories of uncertainty explains the blindness of modern economics to economic phenomena such as instability, slumps or excessive booms. Based on these findings the author develops a new approach that legitimizes a New Uncertainty Paradigm in economics.
