This book presents a multidimensional perspective on the interlinkage between human development, community characteristics and public service delivery with special reference to India. The chapters in the book analyze the influence of public service delivery on human development from neo-classical as well as Marxian point of view. Thus, the expositions in the book provides a balanced mix of macro and micro approaches in the study of development. The analytical discussions are supplemented by case studies and empirical estimates so as to demonstrate the applicability of the theory and the theoretical discourse about human development, community network and the success and failures of critical public services in the Indian context. The methodology followed in the chapters involves critical survey of existing literature, case studies, field survey and use of econometric techniques as well as statistical tools of index construction. While contributors are primarily scholars from neo-classical economics discipline, some are intellectuals from the field of political economy and development studies. Given the wide array of development perspectives, this book is of interest not only to students and researcher of development economics, social science and management, but also a valuable reading for development practitioners and policy makers, who would be interested in understanding how community and public institutions interact to determine access to health, education and social security services that shapes the wellbeing of disadvantaged populations. The lessons and implications are extremely pertinent to other emerging economies, in particular those in South Asia.

Biological visual systems employ massively parallel processing to perform real-world visual tasks in real time. A key to this remarkable performance seems to be that biological systems construct representations of their visual image data at multiple scales. A Pyramid Framework for Early Vision describes a multiscale, or `pyramid', approach to vision, including its theoretical foundations, a set of pyramid-based modules for image processing, object detection, texture discrimination, contour detection and processing, feature detection and description, and motion detection and tracking. It also shows how these modules can be implemented very efficiently on hypercube-connected processor networks. A Pyramid Framework for Early Vision is intended for both students of vision and vision system designers; it provides a general approach to vision systems design as well as a set of robust, efficient vision modules.

This volume provides a rigorous and analytical perspective on the pressing issue of making economic progress consistent with environmental conservation. It proposes formal definitions of sustainability, embeds them in dynamic models and models of uncertainty, and explores the concepts and their implications. It presents a wide-ranging approach to formalizing sustainability and bringing it within the realm of economic theory. Environmental sustainability of growth depends on the interactions between the biosphere and the process of economic growth. The analysis of the dynamics of such a complex system requires the use of sophisticated dynamic methods in order to take account of the most relevant implications for social welfare, such as the relationship between economics and ethics, intergenerational distribution of resources, and the impact of economic policy on environmental conservation. The complexity of the object of the analysis involves a high degree of uncertainty coupled with a serious risk of irreversibility of the consequences of present decisions. Therefore, environmental risks are often very difficult to analyze and control. These problems may be faced and solved only by developing new ideas and approaches, some of which are explored in this book.
In recent years there have been major advances in the fields of cardiovascular nuclear medicine and cardiac magnetic resonance imaging. In nuclear cardiology more adequate tomographic systems have been designed for routine cardiac use, as well as new or improved quantitative analytic software packages both for planar and tomographic studies implemented on modern state-of-the-art workstations. In addition, artificial intelligence techniques are being applied to these images in attempts to interpret the nuclear studies in a more objective and reproducible manner. Various new radiotracers have been developed, such as antimyosin, labeled isonitriles, metabolic compounds, etc. Furthermore, alternative stress testing with dipyridamole and dobutamine has received much attention in clinical cardiac practice. Magnetic resonance imaging is a relative newcomer in cardiology and has already shown its merits, not only for anatomical information but increasingly for the functional aspects of cardiac performance. This book covers almost every aspect of quantitative cardiovascular nuclear medicine and magnetic resonance imaging. It will assist the nuclear medicine physician, the radiologist, the physicist/image processing specialist and the clinical cardiologist in understanding the nuclear medicine techniques used in cardiovascular medicine, and in increasing our knowledge of cardiac magnetic resonance imaging.

It examines methods for separating the signal of physical interest from contamination by unwanted noise, and for investigating the phase space of the chaotic signal and its properties. The emphasis throughout is on the use of modern mathematical tools for investigating chaotic behaviour to uncover properties of physical systems, requiring knowledge of dynamical systems at the advanced undergraduate level and some knowledge of Fourier transforms and other signal processing methods.
These essays provide both an overview of Bruno Bettelheim's contributions to psychoanalysis and education and a reflection on present issues confronting child psychiatry, education, and the social sciences. It will point to new directions for scholarly study and psychoanalytic intervention.
This book describes the importance of sustainable livestock production from a food security perspective in the changing climate scenario. It covers the amelioration of climate change impacts and describes the various mitigation strategies to reduce enteric methane emissions. The book targets sustainable livestock production by covering diverse concepts of amelioration, mitigation, and policy up-gradation. Further, it examines various adverse impacts of climate change on growth, meat, milk, and reproduction in livestock. Most importantly, the book covers novel aspects of quantifying heat stress response of livestock based on non-invasive methodologies, including infrared thermal imaging, sensor-based applications, hair, urine, and fecal cortisol estimation. Particular emphasis was given to describing the skin-based novel approaches to establish climate resilience in indigenous breeds. The book provides detailed descriptions of alleviating climate change impacts on shelter management, nutritional interventions, and genetics-based strategies involving advanced genomic tools. Lastly, it highlights the livestock species which could be considered ideal climate-resilient animal models to withstand the adversities associated with climate change.
This book urges readers to develop a radical capacity to unthink and rethink interculturality, through multiple, pluri-perspectival and honest dialogues between the authors, and their students. This book does not give interculturality a normative scaffolding but envisages it differently by identifying some of its polyphonic textures. China's rich engagement with interculturality serves to support the importance of being curious about other ways of thinking about the notion beyond the 'West' only. As such, the issues of culture, identity, language, translation, intercultural competence and silent transformations (amongst others) are re-evaluated in a different light. This is a highly informative and carefully presented book, providing scientific insights for readers with an interest in interculturality.
This book is a study of the change and continuity in paradigms in China studies, both inside and outside of China. In the last few years, the United States and China appeared to be moving in the direction of "de-coupling," indicating that the engagement policy with China in the last four decade is ending. The "modernization theory" that is the theoretical foundation of the engagement policy has proved to be insufficient. This situation calls for a reexamination of the field of China studies. Historically, scholarly paradigms shifts often went hand in hand with drastic social change. As we have entered an era of great uncertainty, it is constructive to reflect on the paradigms in China studies in the past and explore the possibility of new paradigms in the future. How are the shifts of major theories, methods and paradigms in China studies in the west related to social change? How did some of China's paradigms impact on the country's social change and developments?This book will appeal to a wide readership, including scholars and graduate students, upper division undergraduate students of China studies, Asian studies.
This book focuses on chemical reactions and processing under extreme conditions-how materials react with highly concentrated active species and/or in a very confined high-temperature and high-pressure volume. Those ultimate reaction environments created by a focused laser beam, discharges, ion bombardments, or microwaves provide characteristic nano- and submicron-sized products and functional nanostructures. The book explores the chemistry and processing of metals and non-metals as well as molecules that are strongly dependent on the energy deposition processes and character of the materials. Descriptions of a wide range of topics are given from the perspective of a variety of research methodologies, material preparations, and applications. The reader is led to consider and review how a high-energy source interacts with materials, and what the key factors are that determine the quality and quantity of nanoproducts and nano-processing.
