Information security concerns the confidentiality, integrity, and availability of information processed by a computer system. With an emphasis on prevention, traditional information security research has focused little on the ability to survive successful attacks, which can seriously impair the integrity and availability of a system. This text uses database trusted recovery, as an example, to illustrate the principles of trusted recovery in defensive information warfare. Traditional database recovery mechanisms do not address trusted recovery, except for complete rollbacks, which undo the work of benign transactions as well as malicious ones, and compensating transactions, whose utility depends on application semantics. Database trusted recovery faces a set of unique challenges. In particular, trusted database recovery is complicated mainly by the presence of benign transactions that depend, directly or indirectly on malicious transactions and the requirement by many mission-critical database applications that trusted recovery should be done on-the-fly without blocking the execution of new user transactions.This book proposes an alternative model and a set of innovative algorithms for database trusted recovery. Both read-write dependency-based and semantics-based trusted recovery algorithms are proposed, together with static and dynamic database trusted recovery algorithms. These algorithms can typically save a lot of work by innocent users and can satisfy a variety of attack recovery requirements of real world database applications.

Providing a window on educational leadership from an Asian cultural perspective, Liu and Thien’s edited collection describes how educational leadership is linked with national culture in the context of different Asian countries. While much of the scholarship on this topic has been built on Western paradigms, this book examines the measurement of school leadership from a diverse lens by taking cultural context into account while examining educational leadership. Drawing on cross-cultural perspectives, the authors investigate the relationship between leadership for learning and societal culture, in addition to the relationship between leadership style and culture. The text provides a theoretical basis for understanding leadership in the context of Asian countries, and offers practical suggestions for identifying effective, and culturally sensitive leadership practices in similar cultural contexts.An excellent resource for graduate students, researchers in comparative education, educational practitioners looking to improve their education practices, and anyone interested in cultural leadership practices.

Challenging the Western view of idols as objects of worship, this book explores the role that male idols play in fashion and cosmetics brand marketing in mainland China, Hong Kong, and Macau; including the role of the female gaze. It examines idols in the more modern, pan-Asian sense of the word - as objects of social devotion, worshipped by the adoring masses and, in China and Korea, as objects of social and moral uplift. The contemporary idol wields great power - the power to influence taste, and to sell - and Male Idols and Branding in Chinese Luxury focuses on their ability to arouse the consumer appetite to buy. In China, popular culture idols play a vital role in the luxury fashion and cosmetics industries as brand ambassadors and this volume fills a critical gap in the English-language literature on this key element of the marketing industry, bringing together authors from the United States and China, and featuring case studies on idols Wang Yibo and Xiao Zhan. Through considering the subtleties of branding and marketing in China, Korea, and Japan, and the relationship of Chinese idols to fans and consumers in other Asian countries, the authors delve into brand-idol collaborations, particularly through lenses of brand image and toxic fan culture.

Motivation for the Book This book seeks to establish the state of the art in the cyber situational awareness area and to set the course for future research. A multidisciplinary group of leading researchers from cyber security, cognitive science, and decision science areas elab orate on the fundamental challenges facing the research community and identify promising solution paths. Today, when a security incident occurs, the top three questions security admin istrators would ask are in essence: What has happened? Why did it happen? What should I do? Answers to the ?rst two questions form the core of Cyber Situational Awareness. Whether the last question can be satisfactorily answered is greatly de pendent upon the cyber situational awareness capability of an enterprise. A variety of computer and network security research topics (especially some sys tems security topics) belong to or touch the scope of Cyber Situational Awareness. However, the Cyber Situational Awareness capability of an enterprise is still very limited for several reasons: • Inaccurate and incomplete vulnerability analysis, intrusion detection, and foren sics. • Lack of capability to monitor certain microscopic system/attack behavior. • Limited capability to transform/fuse/distill information into cyber intelligence. • Limited capability to handle uncertainty. • Existing system designs are not very “friendly” to Cyber Situational Awareness.

This book explores turnaround leadership in Southeast Asian countries across four themes: principal competencies and leadership frameworks, country-specific practices, teacher leadership and empowerment, and system leadership for school transformation. The chapters collectively contribute to a unified understanding of how theoretical models intersect with real-world challenges and strategies to improve low-performing schools. Emphasising a flexible, context-driven approach over a one-size-fits-all model, the book underscores the importance of adapting leadership strategies to diverse educational environments. While rooted in Southeast Asia, its insights are globally relevant, offering guidance for scholars, policymakers, and practitioners aiming to advance educational equity and sustainable school improvement through contextually grounded leadership practices. This book also encourages meaningful cross-country learning and policy development. Professor Kenneth Leithwood, University of Toronto, CanadaFeaturing qualitative evidence from schools in 11 Southeast Asian countries, this book provides a carefully grounded and much needed non-western perspective on the meaning of successful school leadership and the culturally sensitive task of improving the performance of underperforming schools. It is an excellent resource for both practicing school leaders and researchers. Professor Coby Meyers, University of Virginia, United StatesThe rapid improvement of underserved schools—and the students they serve—remains a critical topic worldwide. Liu and Thien’s focus on Southeast Asia is a timely and comprehensive account of various challenges to leading school turnaround in an array of contexts. The attention paid to system, school, and teacher leaders in these challenging circumstances offer important insights into how such efforts can be successful in Southeast Asia and elsewhere while illuminating the various complexities to overcome. Professor Jingping Sun, University of Alabama, United StatesWhat distinguishes successful school leaders from others is the breadth and accumulation of practices and strategies they enact and employ, as well as the frequency and intensity with which they apply them effectively with precise timing to achieve success, driven by resilience, passion, contextual intelligence, political acuity, and above all, a strong moral purpose. As Walker and Dimmock commented, our understanding of educational leadership remains incomplete if the bulk of theory and practice in the field are drawn from Anglo-Saxon countries. This explains the unique contribution of this book, which broadens our understanding of educational leadership to turn around schools in Southeast Asian countries.
