The study of electronic structure of materials is at a momentous stage, with new computational methods and advances in basic theory. Many properties of materials can be determined from the fundamental equations, and electronic structure theory is now an integral part of research in physics, chemistry, materials science and other fields. This book provides a unified exposition of the theory and methods, with emphasis on understanding each essential component. New in the second edition are recent advances in density functional theory, an introduction to Berry phases and topological insulators explained in terms of elementary band theory, and many new examples of applications. Graduate students and research scientists will find careful explanations with references to original papers, pertinent reviews, and accessible books. Each chapter includes a short list of the most relevant works and exercises that reveal salient points and challenge the reader.
Sustainable development is capturing the attention of planners, politicians and business leaders. Within the academic sphere its study is increasingly breaching disciplinary boundaries to become a focus of attention for natural and social scientists alike. But in studying such a key concept, it is vital that there is a clear definition of what it means, how it is applied on the ground, and the influence it exerts upon people's perceptions of change in the physical environment, economic activity and society. Exploring Sustainable Development is a major new text which provides a multifaceted introduction to key areas of study in this field, examining sustainability at the full range of spatial scales from the local to the global. Building on existing theory it demonstrates the unique contributions that thinking geographically about space, place and human-environment relationships can bring to the analysis of sustainable development. This book explores different interpretations of sustainable development in both theory and practice, in developed and developing countries, and in rural and urban areas. It pays particular attention to the local, national and international politics of implementation, the future of climate and energy, the role of business, and different conceptions of agricultural sustainability. This wide-ranging text is ideal for undergraduates and postgraduates in geography, environmental science, development studies, and related social and political sciences.
Loss of biodiversity is one of the great environmental challenges facing humanity but unfortunately efforts to reduce the rate of loss have so far failed. At the same time, these efforts have too often resulted in unjust social outcomes in which people living in or near to areas designated for conservation lose access to their territories and resources. In this book the author argues that our approach to biodiversity conservation needs to be more strongly informed by a concern for and understanding of social justice issues. Injustice can be a driver of biodiversity loss and a barrier to efforts at preservation. Conversely, the pursuit of social justice can be a strong motivation to find solutions to environmental problems. The book therefore argues that the pursuit of socially just conservation is not only intrinsically the right thing to do, but will also be instrumental in bringing about greater success. The argument for a more socially just conservation is initially developed conceptually, drawing upon ideas of environmental justice that incorporate concerns for distribution, procedure and recognition. It is then applied to a range of approaches to conservation including benefit sharing arrangements, integrated conservation and development projects and market-based approaches such as sustainable timber certification and payments for ecosystem services schemes. Case studies are drawn from the author's research in Rwanda, Uganda, Tanzania, Laos, Bolivia, China and India.
In the late 1950's and early 1960's, a series of studies was installed in the central hardwood forest to determine if size of clearcut opening affects the growth rate and species composition of new stands. In 1991, about 30 years after cutting, stand data were collected in 89 openings ranging in size from 0.04 to 1.61 acres. Species composition varied from locations in West Virginia to those in Illinois and from Ohio to Kentucky. For example, there were more maple and birch in West Virginia than in Illinois, regardless of opening size. Some of the difference in species composition and growth rate is related to site quality but there also are differences due to size of opening. Most of the oak and hickory were on the poorer sites while yellow-poplar was more abundant on the better sites. The number of stems per acre increased with opening size; however, the number of stems of shade-tolerant species constituted a greater proportion of the stand in small openings (
