Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Everyone needs security: Nations need national security, corporations need corporate security, individuals need personal security, cybersecurity, AI security. What is the common denominator of these security concepts Security and science are the building blocks of the modern civilization. Science gave us the powers to change the world. Security should protect us from abuses of those powers. Yet humans have been hesitant to apply the methods of science to the problems of security. This core security-science (SecSci) textbook is a step in that direction.While many students pursue security out of genuine interest, most security curricula are plastered with industry buzzwords and policy slogans, driven by market incentives and government funding. The result is the attackers get richer, and their victims get poorerwhile security experts inhabit the realm of informal narratives in-between. Before joining the fray, some students want to understand it. This textbook arose from the authors' efforts to cater to such students by peeling off the veils of expertise and replacing them with explanations and simple mathematical models.Topics, goals and features:Understand the basic ideas behind the main security concepts and beyond the buzzwordsCybersecurity and computer security are not as different from physical security and national security as they make you think.Physical space is described by its geometry, but what is the geometry of cyberspace Different programming languages and different network and computer architectures require different security tools. Learn the security methods independent on the differences.Privacy is not a security requirement but the right to be left alone.The more I trust you, the less security and privacy I need from you. But why do I trust you This uniquely informative textbook provides supporting materials for undergraduate and graduate courses on security, privacy, and trust. The early chapters introduce the basic concepts at the beginner level. The later chapters require some technical confidence and intellectual maturity. The book can also be used as an entry point into SecSci research.The authors are professors at the Department of Information and Computer Sciences at the University of Hawai'i at M¿noa.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 240 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This book offers a comprehensive, evidence-based approach to understanding and preventing police misconduct in the twenty-first century. Drawing on empirical research across multiple jurisdictions, it explores how our understanding of police misconduct has evolved over time, tracing the changing view of how misconduct emerges, evolves, and persists within law enforcement organisations. Through detailed analyses of stress, typologies, disciplinary systems, prediction and early intervention, it demonstrates how misconduct can, at times, be identified and either managed or disrupted before escalating into crisis. Integrating perspectives on more advanced analytical methods, including machine learning, network analytics, life-course and longitudinal approaches, this book bridges theory, data, and practice to consider structural and behavioural roots of deviance among police. Rather than treating misconduct solely as an individual failing, it presents misconduct as a systemic challenge that demands holistic, data-driven reform. Combining an understanding of historical research with applied modern insights, it is important reading for policing professionals and researchers seeking to understand and build transparent and ethically resilient interventions for police misconduct.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 148 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This book examines the critical intersection of demographic ageing and climate change in Bangladesh, including comparison with other Asia countries. Located in the dynamic delta system of Southeast Asia, Bangladesh is constantly exposed to extreme weather events, the frequency and intensity of which are exacerbated by climate change. Although these disasters affect the entire population, this book argues that older people are at a distinct and disproportionate risk due to their reduced ability to adapt to severe climate-related shocks. Drawing on extensive qualitative field research, the book provides a detailed account of the vulnerability of older adults in a coastal sub-district in Bangladesh. The analysis draws on in-depth interviews with older men and women, whose narratives provide a powerful perspective on life before, during, and after catastrophic weather events. These accounts reveal an ongoing cycle of vulnerability in which cyclones and floods not only destroy material assets such as homes and livelihoods but also cause profound physical and psychological trauma. The resulting disruption of social support networks, loss of income, and forced migration to survive further exacerbate their insecurity. The study identifies several major causes of vulnerability, including the geophysical exposure of the coastal region, the prevalence of non-resilient housing, profound income insecurity, and a high degree of dependence on family support systems. The analysis carefully distinguishes between formal state initiatives, such as the Old Age Allowance, and informal support systems rooted in community and kinship. It shows how formal programmes can strengthen financial stability and ensure access to essentials, while informal networks provide immediate support and practical assistance in the aftermath of a disaster. By synthesising the concepts of exposure, sensitivity, and adaptation, this book offers evidence-based insights into one of the critical challenges of our time. The findings and recommendations are essential for researchers, policy makers and practitioners in the fields of gerontology, disaster management, and climate adaptation, and are an important resource for efforts to protect vulnerable older populations in Bangladesh and other climate-affected regions around the world, in particular in other Asian countries.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 168 pp. Englisch. …

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Schemata are formal tools for describing inductive reasoning. They opened a new area in the analysis of inductive proofs.The book introduces schemata for first-order terms, first-order formulas and first-order inference systems. Based on general first-order schemata, the cut-elimination-by-resolution (CERES) method developed around the year 2000 is extended to schematic proofs. This extension requires the development of schematic methods for resolution and unification which are defined in this book. The added value of proof schemata compared to other inductive approaches consists in the extension of Herbrand s theorem to inductive proofs (in the form of Herbrand systems, which can be constructed effectively). An application to an analysis of mathematical proof is given. The work also contains and extends the newest results on schematic unification and corresponding algorithms.Core topics covered:first-order schematacut-elimination by resolutionpoint transition systemsschematic resolutionHerbrand systemsinductive proof analysisThis volume is the first comprehensive work on first-order schemata and their applications.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This monograph explores the history of the contribution to ballistics by the American mathematician Gilbert Ames Bliss during World War I. Drawing on the then-evolving calculus of variations, Bliss pioneered a novel technique for solving the problem of differential variations in ballistic trajectory. Called Bliss' adjoint method, this technique was both hailed and criticized at the time: it was seen as both a triumphant application of pure mathematics to an applied problem and as a complex intrusion of higher mathematics into the jobs of military personnel not particularly interested in these matters. Although he received much praise immediately after the War, the details of Bliss' work, its furthering of pure mathematical thought, and its absorption into mainstream ballistic work and instruction have never been adequately examined.Gluchoff explores the mathematics of Bliss' work and the strands from which his technique was developed. He then documents the efforts to make the adjoint method accessible to military officers and the conflicts that emerged as a result both between mathematicians and officers and among mathematicians themselves. The eventual absorption of the adjoint method into range firing table construction is considered by looking at later technical books which incorporate it, and, finally, its influence on the ongoing development of functional calculus is detailed.From Frechet Differentials to Firing Tables will appeal to historians of mathematics, physics, engineering, and warfare, as well as current researchers, professors, and students in these areas.Springer Nature c/o IBS, Benzstrasse 21, 48619 Heek 404 pp. Englisch.…
