Bøker av Amartya Sen

Examines the explosive problems of our time and shows how we can move towards peace as firmly as we have spiralled towards war. In this book, the author argues that we are becoming increasingly divided along lines of religion and culture, ignoring the many other ways in which people see themselves, from class and profession to morals and politics.

This title is a synthesis of the thought of economist Amartya Sen, who views economic development as a means to extending freedoms rather than an end in itself. By widening his outlook to include poverty, tyranny, lack of opportunity, individual rights, and political structures, Professor Sen provides a useful overview of the development process.

The sensor cloud is a new model of computing paradigm for Wireless Sensor Networks (WSNs), which facilitates resource sharing and provides a platform to integrate different sensor networks where multiple users can build their own sensing applications at the same time. It enables a multi-user on-demand sensory system, where computing, sensing, and wireless network resources are shared among applications. Therefore, it has inherent challenges for providing security and privacy across the sensor cloud infrastructure. With the integration of WSNs with different ownerships, and users running a variety of applications including their own code, there is a need for a risk assessment mechanism to estimate the likelihood and impact of attacks on the life of the network. The data being generated by the wireless sensors in a sensor cloud need to be protected against adversaries, which may be outsiders as well as insiders. Similarly, the code disseminated to the sensors within the sensor cloud needs to be protected against inside and outside adversaries. Moreover, since the wireless sensors cannot support complex and energy-intensive measures, the lightweight schemes for integrity, security, and privacy of the data have to be redesigned.The book starts with the motivation and architecture discussion of a sensor cloud. Due to the integration of multiple WSNs running user-owned applications and code, the possibility of attacks is more likely. Thus, next, we discuss a risk assessment mechanism to estimate the likelihood and impact of attacks on these WSNs in a sensor cloud using a framework that allows the security administrator to better understand the threats present and take necessary actions. Then, we discuss integrity and privacy preserving data aggregation in a sensor cloud as it becomes harder to protect data in this environment. Integrity of data can be compromised as it becomes easier for an attacker to inject false data in a sensor cloud, and due to hop by hop nature, privacy of data could be leaked as well. Next, the book discusses a fine-grained access control scheme which works on the secure aggregated data in a sensor cloud. This scheme uses Attribute Based Encryption (ABE) to achieve the objective. Furthermore, to securely and efficiently disseminate application code in sensor cloud, we present a secure code dissemination algorithm which first reduces the amount of code to be transmitted from the base station to the sensor nodes. It then uses Symmetric Proxy Re-encryption along with Bloom filters and Hash-based Message Authentication Code (HMACs) to protect the code against eavesdropping and false code injection attacks.

This volume is the last of three addressing a wide range of policy issues relating to the role of public action in combating hunger and deprivation in the modern world. It deals with the background nutritional, economic, social, and political aspects of the problem of world hunger.

An introductory essay in this book interrelates the writer's diverse concerns, and also analyzes discussions generated by the original papers, focusing on the underlying issues of economic analysis and methods.

The Country of First Boys is Amartya Sen's intellectual journey through the past and present to seek an understanding of India's history and the demands of its future. In this collection, Sen examines justice, identity, deprivation, inequalities, gender politics, education, the media, and the importance of getting your priorities right.

Is justice an ideal, for ever beyond our grasp, or something that may actually guide our practical decisions and enhance our lives? This book offers a fresh approach to mainstream theories of justice. It shows how the principles of justice in the modern world must avoid parochialism and address vital questions of global injustice.

This title brings together and develops some of the most important economic, social, and ethical ideas Sen has explored. It examines the claims of equality in social arrangements, stressing that we should be concerned with people's capabilities rather than either their resources or their welfare.

Rationality and freedom are among the most profound and contentious concepts in philosophy and the social sciences. In two volumes on rationality, freedom, and justice, distinguished economist and philosopher Sen brings clarity and insight to these issues. This volume-the first of the two-is principally concerned with rationality and freedom.

Amartya Sen reconsiders the idea of 'the standard of living'. He rejects the more conventional economic interpretations in terms of 'unity' and of wealth or 'opulence', and suggests an interpretation in terms of the 'capabilities and freedoms' that states of affairs do or do not allow.

India is an immensely diverse country with many distinct pursuits, vastly different convictions, widely divergent customs and a veritable feast of viewpoints. This title brings together an illuminating selection of writings on contemporary India.

Containing many of the author's contributions to development economics, this book includes papers on resource allocation in non-wage systems, investment planning, shadow pricing, employment policy, and welfare economics, this text examines development economics in detail.

Based on the 1972 Radcliffe Lectures, this book presents a systematic treatment of the conceptual framework as well as the practical problems of measurement of inequality.

This book focuses on the causes of starvation in general and famines in particular. The traditional analysis of famines is shown to be fundamentally defective, and the author develops an alternative analysis.
