This book provides a novel method based on advantages of mobility model of Low Earth Orbit Mobile Satellite System LEO MSS which allows the evaluation of instant of subsequent handover of a MS even if its location is unknown. This method is then utilized to propose two prioritized handover schemes, Pseudo Last Useful Instant PLUI strategy and Dynamic Channel Reservation DCR-like scheme based respectively on LUI and DCR schemes, previously proposed in literature. The authors also approach a different aspect of handover problem: calls with short durations dropped due to a handover failure. We propose a decision system based on fuzzy logic Rescuing System that allows the rescue of calls with short durations facing a premature at the expense of those lasting for long durations.

Media, Markets, and Morals provides an original ethical framework designed specifically for evaluating ethical issues in the media, including new media. The authors apply their account of the moral role of the media, in their dual capacity as information providers for the public good and as businesses run for profit, to specific morally problematic practices and question how ethical behavior can be promoted within the industry. Brings together experts in the fields of media studies and media ethics, information ethics, and professional ethics Offers an original ethical framework designed specifically for evaluating ethical issues in the media, including new media Builds upon and further develops an innovative theoretical model for examining and evaluating media corruption and methods of media anti-corruption previously developed by authors Spence and Quinn Discloses and clarifies the inherent ethical nature of information and its communication to which the media as providers of information are necessarily committed

Despite the growing interest in the role of psychological trauma in the genesis of psychiatric disorders, few volumes have addressed these issues from a multidisciplinary and international perspective. Given the complexity of reslience and posttraumatic disorder, and given ongoing trauma and violence in many parts of the world, it is crucial to apply such perspectives to review existing knowledge in the field and provide directions for future research. This book has a broad scope. A key focus is PTSD, because of its clinical and health importance, its obvious link with trauma, and its interest for many clinicians and researchers. However, the book also examines resilience and a range of mental health consequences of trauma, because it has become increasingly clear that not all individuals react to trauma in the same way. It is important for mental health professionals to be aware of the broad range of potential responses to trauma, as well as of relevant evidence-based treatments. The book includes chapters that address a wide range of topics on trauma-related disorders, including nosology and classification, epidemiology, neurobiology, pharmacotherapy, and psychotherapy. Each chapter comprises a critical review of the existing literature, aimed at being useful for the practitioner. This is followed by selected commentaries from other authorities on the topic, representing diverse geographical locations and points of view, who refine some of the perspectives offered in the review, provide alternative views, or suggest important areas of future work.
