Political and scientific debates on migration policies have mostly focused on governments' efforts to control or reduce low-skilled, asylum, and irregular migration or to encourage the return migration of these categories. Less research and constructive discourse has been conducted on the role and effectiveness of policies to attract or retain high-skilled workers. An improved understanding of the drivers and dynamics of high-skilled migration is essential for effective policy-making, as most highly developed and emerging economies experience growing shortages of high-skilled labour supply in certain occupations and sectors, and skilled immigration is often viewed as one way of addressing these. Simplistic assumptions that high-skilled migrants are primarily in pursuit of higher wages raise the expectation that policies which open channels for high-skilled immigration are generally successful. Although many countries have introduced policies aimed at attracting and facilitating the recruitment of high-skilled workers, not all recruitment efforts have had the desired effects, and anecdotal evidence on the effectiveness of these programmes is rather mixed. The reason is that the rather narrow focus on migration policy coincides with a lack of systematic and rigorous consideration of other economic, social, and political drivers of migration, which may be equally - or sometimes even more - important than migration policies per se. A better understanding of migration policies, their making, consequences and limitations, requires a systematic knowledge of the broader economic, social and political structures and their interaction in both origin and destination countries. This book enhances this vibrant field of social scientific enquiry by providing a systematic, multidisciplinary, and global analysis of policies driving international high-skilled migration processes in their interaction with other migration drivers at the individual, city, national, and international level.

Through its exploration of the spatial dimension of risk, this book offers a brand new approach to theorizing risk, and significant improvements in how to manage, tolerate and take risks. A broad range of risks are examined, including natural hazards, climate change, political violence, and state failure. Case studies range from the Congo to Central Asia, from tsunami in Japan and civil war affected areas in Sri Lanka to avalanche hazards in Austria. In each of these cases, the authors examine the importance and role of space in the causes and differentiation of risk, in how we can conceptualize risk from a spatial perspective and in the relevance of space and locality for risk governance. This new approach - endorsed by Ragnar Löfstedt and Ortwin Renn, two of the world's leading and most prolific risk analysts - is essential reading for those charged with studying, anticipating and managing risks.

Affordable and effective domestic wastewater treatment is a critical issue in public health and disease prevention around the world, particularly so in developing countries which often lack the financial and technical resources necessary for proper treatment facilities. This practical guide provides state-of-the-art coverage of methods for domestic wastewater treatment and provides a foundation to the practical design of wastewater treatment and re-use systems. The emphasis is on low-cost, low-energy, low-maintenance, high-performance 'natural' systems that contribute to environmental sustainability by producing effluents that can be safely and profitably used in agriculture for crop irrigation and/or in aquaculture, for fish and aquatic vegetable pond fertilization. Modern design methodologies, with worked design examples, are described for waste stabilization ponds, wastewater storage and treatment reservoirs; constructed wetlands, upflow anaerobic sludge blanket reactors, biofilters, aerated lagoons and oxidation ditches. This book is essential reading for engineers, academics and upper-level and graduate students in engineering, wastewater management and public health, and others interested in sustainable and cost-effective technologies for reducing wastewater-related diseases and environmental damage.

The need to continually discover new agents for the control or treatment of invertebrate pests and pathogens is undeniable. Agriculture, both animal and plant, succeeds only to the extent that arthropod and helminth consumers, vectors and pathogens can be kept at bay. Humans and their companion animals are also plagued by invertebrate parasites. The deployment of chemical agents for these purposes inevitably elicits the selection of resistant populations of the targets of control, necessitating a regular introduction of new kinds of molecules. Experience in other areas of chemotherapy has shown that a thorough understanding of the biology of disease is an essential platform upon which to build a discovery program. Unfortunately, investment of research resources into understanding the basic physiology of invertebrates as a strategy to illuminate new molecular targets for pesticide and parasiticide discovery has been scarce, and the pace of introduction of new molecules for these indications has been slowed as a result. An exciting and so far unexploited area to explore in this regard is invertebrate neuropeptide physiology. This book was assembled to focus attention on this promising field by compiling a comprehensive review of recent research on neuropeptides in arthropods and helminths, with contributions from many of the leading laboratories working on these systems.
