The rapid growth of the world population - nearly six-fold over the last hundred years - combined with the rising number of technical installations especially in the industrialized countries has lead to ever tighter and more strained living spaces on our planet. Because ofthe inevitable processes oflife, man was at first an exploiter rather than a careful preserver of the environment. Environmental awareness with the intention to conserve the environment has grown only in the last few decades. Environmental standards have been defined and limit values have been set largely guided, however, by scientific and medical data on single exposures, while public opinion, on the other hand, now increasingly calls for astronger consideration of the more complex situations following combined exposures. Furthermore, it turned out that environmental standards, while necessarily based on scientific data, must also take into account ethical, legal, economic, and sociological aspects. A task of such complexity can only be dealt with appropriately in the framework of an inter disciplinary group.
In its first English-language edition, this book introduces the many-faceted interactions of animal populations with their habitats. From soil fauna, ants and termites to small and large herbivores, burrowing mammals and birds, the author presents a comprehensive analysis of animals and ecosystems that is as broad and varied as all nature. Chapter 2 addresses the functional role of animals in landscape ecosystems, emphasizing fluxes of energy and matter within and between ecosystems, and the effects of animals on qualitative and structural habitat change. Discussion includes chapters on the role of animal population density and the impacts of native herbivores on vegetation and habitats from the tropics to the polar regions. Cyclic mass outbreaks of species such as the larch bud moth in Switzerland, the mountain pine beetle and the African red-billed weaver bird are described and analyzed. Other chapters discuss Zoochory – the dispersal of seeds by ants, mammals and birds – and the influence of burrowing animals on soil development and geomorphology. Consideration extends to the impact of feral domestic animals. Chapter 5 focuses on problems resulting from introduction of alien animals and from re-introduction of animal species to their original habitats, discusses the effects on ecosystems of burrowing, digging and trampling by animals. The author also addresses keystone species such as kangaroo rats, termites and beavers. Chapter 6 addresses the role of animals in landscape management and nature conservation, with chapters on the impact of newcomer species such as animals introduced into Australia, New Zealand and Europe, and the consequences of reintroduction of species to original habitat. It also discusses the carrying capacity of natural habit, public attitudes toward conversation and more. The final section ponders the effects of climate on interactions between animals and their habitats.
Scholarship often treats the post-Roman art produced in central and north-western Europe as representative of the pagan identities of the new 'Germanic' rulers of the early medieval world. In this book, Matthias Friedrich offers a critical reevaluation of the ethnic and religious categories of art that still inform our understanding of early medieval art and archaeology. He scrutinises early medieval visual culture by combining archaeological approaches with art historical methods based on contemporary theory. Friedrich examines the transformation of Roman imperial images, together with the contemporary, highly ornamented material culture that is epitomized by 'animal art.' Through a rigorous analysis of a range of objects, he demonstrates how these pathways produced an aesthetic that promoted variety (varietas), a cross-cultural concept that bridged the various ethnic and religious identities of post-Roman Europe and the Mediterranean worlds.
This books deals with computer-mediated cooperation and communication scenarios in teaching and learning situations, leisure activities (e.g. laypersons looking for expert information on the internet), and net-based communication at work. Such scenarios will become increasingly important. But the successful use of such computer-mediated settings is not trivial. Cooperative learning and work itself requires special skills and strategies. And the technical settings with sometimes restricted, sometimes new possibilities for communication add problems on top of the cooperation itself. What are the barriers in computer-mediated communication for cooperative learning and work? Which are the most relevant biases in computer-mediated information processing? Based on empirical research the contributors from psychology, education and computer sciences offer different perspectives on the nature and causes of such barriers. The chapters also give an answer to the question how it might be possible to overcome these barriers and biases to fully gain advantage from the new technical opportunities. These results and answers are of interest for students as well as for researchers in all fields related to the use and evaluation of computer software in communication settings.
Radioactive waste (above all highly radioactive wastes from nuclear installations) caused by research, medicine and technology must be disposed of safely. However both the strategies disputed for the disposal of radioactive waste as well as concrete proposals for choosing a location for final waste disposal are highly debatable. An appropriate disposal must conform to both complex, technical requirements and fulfill the radio-biological conditions to appropriately protect man and nature. Ethical, legal and social conditions must also be considered. An interdisciplinary team from various, relevant fields compiled the current status-quo and developed criteria and strategies, which on the one hand meet the requirements of optimal warning and prevention of risk for present and future generations, and additionally on the other hand meet the needs of what current society agrees what is expected to be allowed. This study can be understood as an advanced and continuing contribution to the corresponding scientific specialized debates, due to its interdisciplinary treatment. At the same time it serves as a fundamentally informing contribution to public and political debates, offering an easily comprehensible executive summary and precise content recommendations.
The start of the eighteenth century witnessed the elevation of Prussia to monarchic status, a reflection of the rising importance of the Hohenzollern dynasty within the Empire as well as in Central Europe. In tandem with this, Berlin came to the fore as the capital city of Brandenburg, with the establishment there of the royal court. This volume makes available for the first time a selection of the diverse printed and visual materials relating to these developments. In their introduction to the documents, the editors explore the historical, political and cultural context of the rise of the Hohenzollerns and the significance of the 1701 coronation of Friedrich III as King in Prussia. The materials provided in the original, as well as in English translation, are wide-ranging. Points of focus include the dynasty's cultivation of the arts and learning, its festive culture, the structure of the court and the nature of Friedrich's reign. Particular attention is given to the ceremonial procedure and festivities surrounding his coronation recorded by the court poet, Johann von Besser. This collection of materials acts as a commentary on Baroque kingship, revealing the manner in which the early eighteenth-century monarch wished to present himself to the outside world and enhance his legitimacy among European rulers. It also offers valuable insights into a key stage in the political and cultural history of Brandenburg-Prussia, the consequences of which exercised a crucial impact on the development of Germany and the history of Europe.
