Information Cosmopolitics explores interaction between nationalist and information sharing practices in academic communities with a view to understanding the potential impacts of these interactions. This book is also a resounding critique of existing theories and methods as well as the launching point for the proposition of an alternate approach. Dominant approaches in the Information Behaviour (IB) field are investigated, as well as questions existing theoretical approaches to nationalism and cosmopolitanism. The concept of information cosmopolitics is introduced as an approach for tracing information practices and enabling research participants to perform their own narratives and positionings, and that the focus of information studies should be on tracing the continuous circulation of processes of individualisation and collectivization.

• Provide an alternative to the dominant approaches in the field of Information Behaviour
• Offers a novel theoretical model to trace information practices
• Questions existing approaches to nationalism and cosmopolitanism

In the digital world, the need to protect communications increases every day. While traditional digital encryption methods are useful, there are many other options for hiding your information. Information Hiding in Speech Signals for Secure Communication provides a number of methods to hide secret speech information using a variety of digital speech coding standards. Professor Zhijun Wu has conducted years of research in the field of speech information hiding, and brings his state-of-the-art techniques to readers of this book, including a mathematical model for information hiding, the core concepts of secure speech communication, the ABS-based information hiding algorithm, and much more.

This book shows how to implement a secure speech communication system, including applications to various network security states. Readers will find information hiding algorithms and techniques (embedding and extracting) that are capable of withstanding the advanced forms of attack. The book presents concepts and applications for all of the most widely used speech coding standards, including G.711, G.721, G.728, G.729 and GSM, along with corresponding hiding and extraction algorithms. Readers will also learn how to use a speech covert communication system over an IP network as well as a speech secure communication system applied in PSTN.

• Presents information hiding theory and the mathematical model used for information hiding in speech.
• Provides a number of methods to hide secret speech information using the most common digital speech coding standards.

Science is first and foremost an intellectual activity, an activity of thought. Therefore, how do we, as information scientists, respond intellectually to what is happening in the world of information and knowledge development, given the context of new sociocultural and knowledge landscapes? Information Science as an Interscience poses many challenges both to information science, philosophy and to information practice, and only when information science is understood as an interscience that operates in a multifaceted way, will it be able to comply with these challenges. In the fulfilment of this task it needs to be accompanied by a philosophical approach that will take it beyond the merely critical and linear approach to scientific work. For this reason a critical philosophical approach is proposed that will be characterised by multiple styles of thinking and organised by a compositional inspiration. This initiative is carried by the conviction that information science will hereby be enabled to make contributions to significant knowledge inventions that may bring about a better world. Chapters focus on the rethinking of human thinking, our unique ability that enables us to cope with the world in which we live, in terms of the unique science with which we are involved. Subsequent chapters explore different approaches to the establishment of a new scientific spirit, the demands these developments pose for human thinking, for questions of method and the implications for information science regarding its proposed functioning as a nomad science in the context of information practice and information work. Final chapters highlight the proposed responsibility of focusing on information and inventiveness and new styles of information and knowledge work.

• focuses on rethinking information science to achieve a constructive scientific approach
• provides an alternative methodological approach in the study of information science
• shows how a change in scientific approach will have vast implications for the understanding and dissemination of knowledge
• presents the implications of a new approach for knowledge workers, and the dynamics of their work
• explores the future of thinking about science, knowledge and its nature and the ethical implications

Informed and Healthy: Theoretical and Applied Perspectives on the Value of Information to Health Care focuses on two major issues: the value attributed to information by users and its effect on health care; and, a new model of information behavior in which the value of information drives various information activities (unlike many information models which tend to give prominence to information needs). The inductive development of the model is explained, with associated implications for theory and transferability or applicability elsewhere.

The book uses a case study of the health information system in Uganda and expands the analysis by comparing it to other systems utilized by different countries in diverse levels of development. Topics such as access and use of information; value attribution and effect on health outcomes; and modelling information behavior and its implications on health informatics are discussed in detail. This book is a valuable resource for health professionals, planners, and policy makers, as well as researchers interested in health information systems and their applicability in different environments.

• Provides a new model of information behaviour that emerges inductively from qualitative data
• Focuses on value of information rather than information needs
• Explains in detail the methodological approach used to value attribution
• Serves as a valuable resource for health professionals, planners, and policy makers, as well as researchers interested in health information systems and their applicability in different environments

By fostering principles of systems thinking and informed learning though an inclusive, participatory design process that advances information exchange, reflective dialogue, and knowledge creation, the Informed Systems Approach promotes conceptual change in workplace organizations. Informed Systems explores theory-based participatory action research and provides examples of agile process models for activating sustainable design, dialogue, and reflection processes in today’s organizations. This book also examines forward thinking frameworks for academic libraries, and how they can be used in the context of dynamically changing scholarly communications. Chapters further the expression of collaborative information practices that enrich information experiences by simultaneously advancing both situated domain knowledge and transferable learning capacity. Design (and redesign) activities well integrated into the workplace culture are expressed through sustainable processes and practices that produce rich information experiences. Informed learning both promotes and sustains continuous learning, including collective reflection on information sources, collaborative practices, and systems functionalities. In these ways, transferable topical understandings and information resiliency manifest action oriented intention to ensure improvements of real world situations.
