Download or read book Non State Actors and Authority in the Global System written by Andreas Bieler and published by Routledge. This book was released on 2004-01-14 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally in International Relations, power and authority were considered to rest with states. But recently, in the light of changes associated with globalisation, this has come under scrutiny both empirically and theoretically. This book analyses the continuing but changing role of states in the international arena, and their relationships with a wide range of non-state actors, which possess increasingly salient capabilities to structure global politics and economics.
Download or read book Emergent Actors in World Politics written by Lars-Erik Cederman and published by Princeton University Press. This book was released on 1997-06-12 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The disappearance and formation of states and nations after the end of the Cold War have proved puzzling to both theorists and policymakers. Lars-Erik Cederman argues that this lack of conceptual preparation stems from two tendencies in conventional theorizing. First, the dominant focus on cohesive nation-states as the only actors of world politics obscures crucial differences between the state and the nation. Second, traditional theory usually treats these units as fixed. Cederman offers a fresh way of analyzing world politics: complex adaptive systems modeling. He provides a new series of models--not ones that rely on rational-choice, but rather computerized thought-experiments--that separate the state from the nation and incorporate these as emergent rather than preconceived actors. This theory of the emergent actor shifts attention away from the exclusively behavioral focus of conventional international relations theory toward a truly dynamic perspective that treats the actors of world politics as dependent rather than independent variables. Cederman illustrates that while structural realist predictions about unit-level invariance hold up under certain circumstances, they are heavily dependent on fierce power competition, which can result in unipolarity instead of the balance of power. He provides a thorough examination of the processes of nationalist mobilization and coordination in multi-ethnic states. Cederman states that such states' efforts to instill loyalty in their ethnically diverse populations may backfire, and that, moreover, if the revolutionary movement is culturally split, its identity becomes more inclusive as the power gap in the imperial center's favor increases.
Download or read book Agile Actors on Complex Terrains written by Graham Room and published by Routledge. This book was released on 2016-06-17 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book assesses the value and relevance of the literature on complex systems to policy-making, contributing to both social theory and policy analysis. For this purpose it develops two key ideas: agile action and transformative realism. The book takes some major themes from complexity science, presents them in a clear and accessible manner and applies them to core problems in sociological theory and policy analysis. Combining complexity science with perspectives from institutionalism and political economy, this book is the first to integrate these fields conceptually, methodologically and in terms of the implications for policy analysis and practice. Room shows how the models and methods of social and complexity science can be jointly deployed and applied to empirical areas of public policy. He demonstrates how complexity science can provide insight into the nonlinear dynamics of the social world, but why these need to be understood by reference to the unequal distribution of power and advantage. Among the sociological debates with which the book engages are those concerned with causation and explanation, rational action and positional competition, and the place of evolutionary concepts in accounts of social change. Among the policy debates are those concerned with evidence and policy, the dynamics of inequality, and libertarian paternalism. The book will appeal to final year undergraduates and postgraduate students in social sciences; scholars in social and policy studies broadly defined; policy-makers who want to go beyond conventional discussions of evidence-based policy-making and cross-national lesson-drawing, and consider how to approach complex and turbulent policy terrains; and a wider range of scholars in other disciplines where complexity science is already well developed.
Download or read book Modern Concurrency in Swift Second Edition written by Kodeco Team and published by Kodeco Incorporated. This book was released on 2023-02-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Learn Modern Swift Concurrency! For years, writing powerful and safe concurrent apps with Swift could easily turn into a daunting task, full of race conditions and unexplained crashes hidden in a massive nesting of callback closures. In Swift 5.5, Apple introduced a new concurrency model featuring the async/await syntax, which lets you write asynchronous code that reads like synchronous code. But like any new feature, here be dragons! So how will you achieve the much-desired mastery of modern Swift concurrency? Modern Concurrency in Swift comes to the rescue, showcasing what you need to know about async/await, tasks, actors and everything in between! Who This Book Is For This book is for intermediate Swift developers who are familiar with writing asynchronous applications and who want to leverage the concurrency features Apple introduced in Swift 5.5 and its evolution throughout the years, to write safer and more predictable asynchronous apps. Topics Covered in Modern Concurrency in Swift Using async/await: Learn how to use the new async/await keywords to define and run asynchronous work. Actors: Find out how to use the actor model to easily protect shared mutable state in a synchronized container. Tasks: You'll dive deeper into the Task type, which powers all asynchronous tasks in Swift's modern concurrency model. Task Groups: Use a Task Group to group multiple tasks together and run them concurrently, while using a familiar Array-like syntax to iterate over the results. Custom Asynchronous Sequences: Leverage the power of async/await in your own asynchronous work, by learning how to create custom AsyncStreams. Testing Asynchronous Code: Asynchronous code can be a challenging beast to test. You'll learn everything you need to tackle this challenge. One thing you can count on: After reading this book, you'll be prepared to leverage Swift's new concurrency features in your app to write safe, performant and predictable asynchronous code.
Download or read book Agency Without Actors written by Jan-Hendrik Passoth and published by Routledge. This book was released on 2012-03-29 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Agency without Actors? New Approaches to collective Action is rethinking a key issue in social theory and research: the question of agency. The history of sociological thought is deeply intertwined with the discourse of human agency as an effect of social relations. In most recent discussions the role of non-humans gains a substantial impact. Consequently the book asks: Are nonhumans active, do they have agency? And if so: how and in what different ways? The volume offers a critical state-of-the-art debate of internationally and nationally leading scholars within Sociology, Social Anthropology and STS on agency (Latour, Law, Michael, Rammert etc.). It fosters the productive exchange of empirical settings and theoretical views by outlining a wide range of novel accounts that link human and non-human agency. It tries to understand social-technical, political and environmental networks as different forms of agency that produce discrete and identifiable entities like humans, animals, technical artifacts. It also asks how different types of (often conflicting) agency and agents actors are distinguished in practice, how they are maintained and how they interfere with each other"--

Download or read book Sociopolitical Ecology written by Frederick L. Bates and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sociopolitical Ecology introduces the concept of `ecological field' to replace that of `ecosystem' and extends the boundaries of self-referential systems to a new, more complex level of analysis. Ecological field refers to an overarching system that contains many self-referential (or autopoietic) systems that interact in a common space, with human beings placed squarely in the middle of all natural ecological networks. The focus of this fascinating study is the interlocking pattern of relations among human beings within an ecological field - what the author designates as `sociopolitical ecology'. The book argues that most societies are not self-contained systems, but rather ecological fields, that is complexes of several interacting systems.

This book was released on 2016-09-19 with total page 1000 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book consists of chapters based on selected papers presented at the EcoDesign2015 symposium (9th International Symposium on Environmentally Conscious Design and Inverse Manufacturing). The symposium, taking place in Tokyo in December 2015, has been leading the research and practices of eco-design of products and product-related services since it was first held in 1999. The proceedings of EcoDesign2011 were also published by Springer. Eco-design of products and product-related services (or product life cycle design) are indispensable to realize the circular economy and to increase resource efficiencies of our society. This book covers the state of the art of the research and the practices in eco-design, which are necessary in both developed and developing countries. The chapters of the book, all of which were peer-reviewed, have been contributed by authors from around the world, especially from East Asia, Europe, and Southeast Asia. The features of the book include (1) coverage of the latest topics in the field, e.g., global eco-design management, data usage in eco-design, and social perspectives in eco-design; (2) an increased number of authors from Southeast Asian countries, with a greater emphasis on eco-design in emerging economies; (3) high-quality manuscripts, with the number of chapters less than half of that of the previous book.
Download or read book Sectoral Systems of Innovation and Production in Developing Countries written by Franco Malerba and published by Edward Elgar Publishing. This book was released on 2009-01-01 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade there has been a dramatic increase in the quantity and quality of research focused on the processes through which technological capabilities are acquired by countries significantly behind the economic frontier, and the institutions that effectively support the catching up process. This book is a splendid contribution to this literature. The concept of a sectoral innovation system is well suited for framing studies of these kinds of questions, and serves well to unify the many interesting empirical studies in the book. Some of those studies are success stories, others of less successful cases. Readers new to this body of research will find this book a great introduction. All readers will learn a lot from it about what is required for and involved in economic development. Richard R. Nelson, Columbia Earth Institute, US and University of Manchester, UK This book examines in detail the features and dynamics of sectoral systems of innovation and production in developing countries. Processes of rapid growth are usually associated with specific sectors such as automobiles, electronics or software, as well as with the transformation of traditional sectors such as agriculture and food. The book shows, however, that the variations across all these sectors in terms of structure and dynamics is so great that a full understanding of these differences is necessary if innovation is to be encouraged and growth sustained. The expert contributors promote this understanding by drawing upon empirical evidence from a wide range of sectoral systems, from traditional to high technology, and across a number of countries. They explore how these systems change and evolve, highlighting policy lessons to be drawn from the analysis. Case studies include the Brazilian aeronautical, pulp and paper industries, the Korean machine tool sector, motorbike manufacture in Thailand and Vietnam, pharmaceuticals and telecommunication equipment in India, ICT in Taiwan, the biofuels sector in Tanzania, salmon farming in Chile and software in Uruguay. Scholars and researchers in the fields of economics development economics in particular and innovation will find this book to be of great interest. Policymakers and managers focussing on innovation and growth in developing countries will also warmly welcome the book.

Download or read book Participants in the International Legal System written by Jean d'Aspremont and published by Taylor & Francis. This book was released on 2011-04-20 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: The international legal system has weathered sweeping changes over the last decade as new participants have emerged. International law-making and law-enforcement processes have become increasingly multi-layered with unprecedented numbers of non-State actors, including individuals, insurgents, multinational corporations and even terrorist groups, being involved. This growth in the importance of non-State actors at the law-making and law-enforcement levels has generated a lot of new scholarly studies on the topic. However, while it remains uncontested that non-State actors are now playing an important role on the international plane, albeit in very different ways, international legal scholarship has remained riddled by controversy regarding the status of these new actors in international law. This collection features contributions by renowned scholars, each of whom focuses on a particular theory or tradition of international law, a region, an institutional regime or a particular subject-matter, and considers how that perspective impacts on our understanding of the role and status of non-State actors. The book takes a critical approach as it seeks to gauge the extent to which each conception and understanding of international law is instrumental in the perception of non-State actors. In doing so the volume provides a wide panorama of all the contemporary legal issues arising in connection with the growing role of non-state actors in international-law making and international law-enforcement processes.
Download or read book Doing Public Good written by R. Pablo Guerrero O. and published by Routledge. This book was released on 2017-07-05 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the contributions of non-public organizations, such as foundations, philanthropies, charities, non-governmental organizations, private businesses, and entrepreneurs to public goods and services. Too often the impact of the contributions of such private actors are overlooked. However, they are playing an increasing role in meeting societal needs across the developing world.Doing Public Good? lays out key elements that need to be considered in evaluating the net results achieved by these private actors. It uses case studies and analysis to show how to answer such questions as: Is it working? How do they and the public know they are doing good? And how to improve? Such questions are particularly important since little is known about the net results of private avenues for delivering public value.The contributors conclude that "doing good" organizations need to be more transparent and accountable regarding their operations and achievements. The book suggests perspectives on how better monitoring and evaluation systems can improve their accountability.
