Immigration divides our globalizing world like no other issue. We are swamped by illegal immigrants and infiltrated by terrorists, our jobs stolen, our welfare system abused, our way of life destroyed--or so we are told. At a time when National Guard units are deployed alongside vigilante Minutemen on the U.S.-Mexico border, where the death toll in the past decade now exceeds 9/11's, Philippe Legrain has written the first book about immigration that looks beyond the headlines. Why are ever-rising numbers of people from poor countries arriving in the United States, Europe, and Australia? Can we keep them out? Should we even be trying? Combining compelling firsthand reporting from around the w...
It is a great privilege to introduce this book devoted to the current and future roles in research and clinical practice of another exciting new development in MRI: Diffusi- weighted MR imaging. This new, quick and non-invasive technique, which requires no contrast media or i- izing radiation, offers great potential for the detection and characterization of disease in the body as well as for the assessment of tumour response to therapy. Indeed, whereas DW-MRI is already ? rmly established for the study of the brain, progress in MR techn- ogy has only recently enabled its successful application in the body. Although the main focus of this book is on the role of DW-MRI in patients with malignant tumours, n- oncological emerging applications in other conditions are also discussed. The editors of this volume, Dr. D. M. Koh and Prof. H. Thoeny, are internationally well known for their pioneering work in the ? eld and their original contributions to the l- erature on DW-MRI of the body. I am very much indebted to them for the enthusiasm and engagement with which they prepared and edited this splendid volume in a record short time for our series Medical Radiology – Diagnostic section.
Intravoxel incoherent motion (IVIM) refers to translational movements which within a given voxel and during the measurement time present a distribution of speeds in orientation and/or amplitude. The concept was introduced in 1986 together with the foundation of diffusion MRI because it had been realized that flow of blood in capillaries (perfusion) would mimic a diffusion process and impact diffusion MRI measurements. IVIM-based perfusion MRI, which does not require injection of any tracer or contrast agent, has been first investigated in the brain, but is now experiencing a remarkable revival for applications throughout the body, especially for oncologic applications, from diagnosis to treatment monitoring. This book addresses a number of highly topical aspects of the field from leading authorities, introducing the concepts behind IVIM MRI, outlining related methodological issues, and summarizing its current usage and potential for clinical applications. It also presents future research directions, both in terms of methodological development and clinical application fields, extending to new, non-perfusion applications of IVIM MRI, such as virtual MR elastography.
For the first time, this book brings together the latest information on the course of PTSD and its development through life. The world's leading experts from the fields of clinical and developmental psychology describe results of their most recent studies, both practical and theoretical, on the occurrence of PTSD in various phases of life, from adolescence to old age. Also discussed in detail are methods of coping with PTSD at different stages of life, including working through and personal growth, both of which are examined in innovative ways.
Sagalassos, once the metropolis of the Western Taurus range (Pisidia, Turkey), was only thoroughly surveyed in 1884 and 1885 by an Austrian team directed by K. Lanckoronski. In 1986-1989 this work was resumed by a British-Belgian team co-directed by Dr. Stephen Mitchell (University College of Swansea) and by Prof. Dr. Marc Waelkens (Catholic University of Leuven). In 1990 Sagalassos became a full scale Belgian project and a leading center for interdisciplinary archaeological and archaeometrical research. Due to its altitude, the site is one of the best preserved towns from classical antiquity, with a rich architectural and sculptural tradition dating from the second century BC to the sixth c...
A satellite symposium entitled "Myelination and Demyelination: Recent Chemical Advances" was held in Helsinki from August 29 to 31, 1977, after the Sixth International Meeting of the International Society for Neurochemistry (ISN) in Copenhagen. Myelin is a nervous tissue structure that is most suitable as a subject of biochemical investigation. It is easy to isolate in a highly purified form, is rather stable even after death, and is af fected by a variety of neurological and other diseases. Its lesions are particularly important in the study of multiple sclerosis, a disease which is relatively prevalent in Finland and has therefore been of interest to a great many Finnish scientists. The fi...
This book provides a wide-ranging overview of the current state of tourist destination management and presents important recent research in the field. Contemporary theoretical and methodological approaches to management and marketing are discussed, and innovative practices with respect to both urban and rural destinations are described with the aid of many interesting case studies from across Europe and beyond. In addition, the volume addresses key issues such as governance, cooperation, the use of social media, and sustainability. A variety of influences on tourism development are examined, and efficient strategies for making destinations distinct are explored. The book will be a welcome addition and update to the existing literature and will be of interest to academics and practitioners alike.
Omertà, the Sicilian code of silence, has been the cornerstone of the Mafia's sense of honour for centuries. Born in the Sicilian hills, omertà carried the Mafia through a hundred years of change, but now at the century's end it is becoming a relic from a bygone age. Honour may be silent - but money talks. New York - a mob boss is assassinated. His nephew Astorre Viola and the head of the city's FBI both launch investigations into the murder. But this time silence spreads like a contagion: the silence of rival gangs, the silence of crooked bankers, even the silence of the courts. The world of the Mafia is riven with greed, and Viola knows that now is the time to claim his destiny...
Wide coverage of soils and perennial cropping systems in the tropicsSynthesis of decades of researchChallenges assumptions on the benefits of plantations for soil fertilityIt is generally assumed that soil fertility decline is widespread in the tropics and that this is largely associated with annual cropping and subsistence farming. In contrast, perennial plant cover (as in plantation agriculture) provides better protection for the soil.This book reviews these concepts, focusing on soil chemical changes under different land-use systems in the tropics. These include perennial crops, annual crops and forest plantations. Two case studies, on sisal plantations in Tanzania and sugar cane in Papua New Guinea, are presented for detailed analysis. The author demonstrates that soil fertility decline is also a problem on plantations.
