It is an indispensable resource for energy researchers, professionals, policymakers, and academics studying sustainability and digital transformation.Presents the symbiotic relationship between digital transformation and energy efficiency in business allowing readers to gain a profound understanding of how digital platforms can be harnessed to drive sustainabilityExplores the intricate challenges and potential obstacles that accompany the implementation of digital transformation in business and uncovers strategies to overcome hurdles and intricaciesContains a curated collection of real-world case studies exemplifying successful integration of digital platforms for energy efficiency and sustainability thereby illuminating best practices and pitfalls

This book offers a systematic and original analysis of how disciplinary pressure shapes food safety regulation in China.Focusing on punishment as a regulatory incentive, the book shows that disciplinary action is driven not only by regulatory failure, but also by public opinion, institutional design and the discretionary space within which regulators work. Combining historical analysis, comparative case studies of Shenzhen and Beijing, and an original multi-city survey, the book opens the “black box” of regulatory discipline and explains how intensified accountability can both strengthen compliance and generate defensive governance. Readers will benefit from a theoretically grounded and empirically rich account of how negative incentives operate in contemporary regulation, and from a deeper understanding of the tensions between discipline, performance and state capacity in China and beyond.Placing China in comparative perspective by drawing broader lessons for regulatory accountability beyond the Chinese case, this book will appeal to scholars and students of regulation, public administration, Chinese politics, governance and food policy, as well as policymakers and practitioners interested in accountability systems.

This detailed volume explores the notable progress in the field of zinc finger proteins (ZFP) study through widely used methods and protocols involving their biological functions and applications. Beginning with a section on the basic biology of ZFPs and design and applications of custom ZFPs, the book continues by covering methods for the evaluation and prevention of ZFN-mediated cytotoxicity as well as a collection of the representative methods of ZFN delivery. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Zinc Finger Proteins: Methods and Protocols aims to prompt both the understanding of ZFP biology and the development of next-generation ZFP therapeutics.

Jia Liu tackles the unruly world of metadata development and implementation through a state-of-the-art overview of major theoretical issues and exemplary practices. Part one of her book elaborates on the general and latest knowledge about metadata and its implementations. Part two discusses an international array of metadata-related practices, projects and applications in the digital library.While the concept of metadata predates the Internet, worldwide interest in its standards and practices is directly linked to the increase in electronic publishing and digital libraries. Yet questions remain, such as: What form should these standards take? Who gets to develop them? How will they do so and how, in turn, will they be implemented?

This book outlines and evaluates the digital reference services in libraries worldwide. The work is based on an international collaborative project between two groups from German and Chinese institutions, during which digital reference services provided by nearly 200 libraries all over the world were evaluated. The book also examines the reasons for the resulting differences; it also contains more generic proposals and perspectives on digital reference services.

This thesis presents original research on how to seamlessly integrate electronics with living biological systems. Jia Liu has used silicon nanowires as active sensors to investigate biological signals at the cellular level. He has also designed nanoelectronic networks into flexible, three-dimensional (3D) and macroporous architectures, which mimic the structure of tissue scaffolds for in vitro 3D integrations with synthetic tissues and in vivo implantation by means of syringe injection. Importantly, the results demonstrate 3D interpenetrations of nanoelectronic networks with neural networks, 3D mapping of tissue activity and long-term implantation with minimal immunoresponses. Further, the book discusses potential applications for pharmacological studies, brain activity mapping and nanoelectronics enabled therapies. The findings presented here have gained wide recognition, including a top research ranking by Chemical & Engineering News and being listed among Scientific American’s10 world changing ideas in 2015.
