Africa is commonly regarded as a "continent on the move" in scholarly observation and mass media reportage. Movement is seen primarily in the direction of Europe. Yet the public debate is characterized by two misconceptions. The first is that high population growth in Africa would almost automatically trigger higher international migration to the neighbouring European continent. There is even talk of a "rush to Europe". The second frequently encountered misconception is that migration and flight in and from Africa is primarily a result of poverty, violent conflicts and environmental degradation. Both are misconceptions that cannot be reconciled with the facts at hand.
Throughout the twentieth century, neuronal researchers knew the adult human brain to be a thoroughly fixed and immutable cellular structure, devoid of any developmental potential. Plastic Reason is a study of the efforts of a few Parisian neurobiologists to overturn this rigid conception of the central nervous system by showing that basic embryogenetic processesÑmost spectacularly the emergence of new cellular tissue in the form of new neurons, axons, dendrites, and synapsesÑcontinue in the mature brain. Furthermore, these researchers sought to demonstrate that the new tissues are still unspecific and hence literally plastic, and that this cellular plasticity is constitutive of the possibility of the human. Plastic Reason, grounded in years of fieldwork and historical research, is an anthropologistÕs account of what has arguably been one of the most sweeping events in the history of brain researchÑthe highly contested effort to consider the adult brain in embryogenetic terms. A careful analysis of the disproving of an established truth, it reveals the turmoil that such a disruption brings about and the emergence of new possibilities of thinking and knowing.
The computer and particularly the Internet have been represented as enabling technologies, turning consumers into users and users into producers. The unfolding online cultural production by users has been framed enthusiastically as participatory culture. But while many studies of user activities and the use of the Internet tend to romanticize emerging media practices, this book steps beyond the usual framework and analyzes user participation in the context of accompanying popular and scholarly discourse, as well as the material aspects of design, and their relation to the practices of design and appropriation.
This book focuses on the European Union as an important actor in international relations and international political economy. The EU negotiates international economic agreements, represents Europe in international organizations, and is a major trading bloc and currency area. To what extent and under what conditions the EU can use its considerable economic power to assert its interests in the international arena is a relevant question for students, researchers and practitioners alike. To explore this question, the textbook introduces the concept of “actorness” and presents an overview of the actorness debate and theories used to explain actorness. In addition, it includes three empirical chapters on trade, finance and climate policy that apply various concepts and theories to study European actorness in the respective policy areas.
A new account of the central role developmental processes play in evolution A new scientific view of evolution is emerging—one that challenges and expands our understanding of how evolution works. Recent research demonstrates that organisms differ greatly in how effective they are at evolving. Whether and how each organism adapts and diversifies depends critically on the mechanistic details of how that organism operates—its development, physiology, and behavior. That is because the evolutionary process itself has evolved over time, and continues to evolve. The scientific understanding of evolution is evolving too, with groundbreaking new ways of explaining evolutionary change. In this book, a group of leading biologists draw on the latest findings in evolutionary genetics and evo-devo, as well as novel insights from studies of epigenetics, symbiosis, and inheritance, to examine the central role that developmental processes play in evolution. Written in an accessible style, and illustrated with fascinating examples of natural history, the book presents recent scientific discoveries that expand evolutionary biology beyond the classical view of gene transmission guided by natural selection. Without undermining the central importance of natural selection and other Darwinian foundations, new developmental insights indicate that all organisms possess their own characteristic sets of evolutionary mechanisms. The authors argue that a consideration of developmental phenomena is needed for evolutionary biologists to generate better explanations for adaptation and biodiversity. This book provides a new vision of adaptive evolution.
