The auroral emissions in the upper atmosphere of the polar regions of the Earth are evidence of the capture of energetic particles from the Sun, streaming by the Earth as the solar wind. These auroral emissions, then, are a window to outer space, and can provide us with valuable information about electrodynamic coupling processes between the solar wind and the Earth's ionosphere and upper atmosphere. Studying the physics of these phenomena extends our understanding of our plasma universe. Ground-based remote-sensing techniques, able to monitor continuously the variations in the signatures of aurorae, in combination with in-situ satellite and rocket measurements, promise to advance dramatically our understanding of the physical processes taking place at the interface of the atmospheres of the Earth and the Sun. Decoding their complexity brings us closer to reliable prediction of communication environments, especially at high latitudes. This understanding, in turn, will help us resolve problems of communication and navigation across polar regions.
The first part of the report deals with occurrence of methylxanthines in foods, beverages, and medicines, and estimates of caffeine intake. In addition, a short review of the pharmacological and toxicological actions of caffeine is given. The second and main part of the report reviews available information from epidemiological studies on the potential health hazards to the human foetus associated with parental intake during pregnancy of caffeine and related methylxanthines in foods, beverages and medicines. The studied adverse effects are influence on fertility, spontaneous abortion, congenital malformation, pre-term delivery, foetal growth retardation, foetal behaviour and effects on neonates, infants and young children. The conclusion of the report demonstrates the need for limiting caffeine exposure during pregnancy. The Nordic Working Group on Food Toxicology and Risk Evaluation (NNT) recognizes that the human exposure to caffeine and related compounds causes a spectrum of pharmacological effects, for instance cardiovascular, renal, neurological and behavioural effects. The increasing use of caffeine and related methylxanthines in various foods and beverages consumed by children and adolescents cause concern. NNT recommends that a full hazard characterization of caffeine and related methylxanthines should be performed with the aim to reach a conclusion about the upper safe level of intake of these compounds.

China’s news sector is a place where newsmakers, advertising executives, company bosses, and Party officials engage one another in contingent and evolving arrangements that run from cooperation and collaboration to manipulation and betrayal. Drawing on long-term ethnographic fieldwork with journalists, editors, and executives at a newspaper in Guangzhou, The Currency of Truth brings its readers into the lives of the people who write, publish, and profit from news in this milieu. The book shows that far from working as mere cogs in a Party propaganda machine, these individuals are immersed in fluidly shifting networks of formal and informal relationships, which they carefully navigate to pursue diverse goals. In The Currency of Truth, Emily H. C. Chua argues that news in China works less as a medium of mass communication than as a kind of currency as industry players make and use news articles to create agreements, build connections, and protect and advance their positions against one another. Looking at the ethical and professional principles that well-intentioned and civically minded journalists strive to uphold, and the challenges and doubts that they grapple with in the process, Chua brings her findings into conversation around “post-truth” news and the “crisis” of professional journalism in the West. The book encourages readers to rethink contemporary news, arguing that rather than setting out from the assumption that news works either to inform or deceive its publics, we should explore the “post-public” social and political imaginaries emerging among today’s newsmakers and remaking the terms of their practice.

In 1981 a sermon was given in Leiden in which the minister called angels, 'a forgotten group'. This book is an attempt to recall a forgotten group into the memory of everyone. We read so much these days about matters concerning the underworld, that we are inclined to forget that an enormous 'upper world' stretches out above us. A world which is also extremely active, and one which is increasingly beginning to intrude. In A Handbook of Angels the author recounts his survey of four hundred people and the spectacular results, which include reportings of real-life sightings of angels. It becomes apparent that, though we may have forgotten about angels, they have not forgotten about us. They are returning to human consciousness on a gigantic scale.

This text gives a rigorous treatment of the foundations of calculus. In contrast to more traditional approaches, infinite sequences and series are placed at the forefront. The approach taken has not only the merit of simplicity, but students are well placed to understand and appreciate more sophisticated concepts in advanced mathematics. The authors mitigate potential difficulties in mastering the material by motivating definitions, results and proofs. Simple examples are provided to illustrate new material and exercises are included at the end of most sections. Noteworthy topics include: an extensive discussion of convergence tests for infinite series, Wallis’s formula and Stirling’s formula, proofs of the irrationality of π and e and a treatment of Newton’s method as a special instance of finding fixed points of iterated functions.
Heterostructure Lasers, Part A: Fundamental Principles deals with the fundamental principles, preparation, and operating characteristics of heterostructure lasers. Each major topic is introduced along with the basic laws that govern the observed phenomena. The expressions relevant to heterostructure lasers are derived from the basic laws, and realistic numerical examples based on the GaAs-AlxGa1-xAs heterostructure are given. This book is comprised of four chapters and begins with a discussion on some of the early studies of injection lasers and an overview of the fundamental concepts of heterostructure lasers. Stimulated emission and room temperature continuous-wave operation with injection lasers are described, together with the fundamentals of waveguiding, gain, and carrier confinement in heterostructures. Optical fields and wave propagation are considered, along with slab-electric waveguides; the relationships between absorption, stimulated emission, and spontaneous emission; optical absorption and emission rates in semiconductors; and electrical properties of heterojunctions. This monograph will be of interest to physicists.
Cognitive disorders are disturbances in the mental process related to thinking, reasoning, and judgement. They include delirium, dementia, and other cognitive disorders. Cognition includes the domains of attention, memory, language, gnosis, visuo-spatial function, praxis, and executive function, and is traditionally distinguished from the emotions or 'feelings'. Cognitive disorders may disturb one domain specifically, as in a selective impairment of memory (amnesia) or language (aphasia), or, more often, a combination of deficits, as in mental retardation and dementia.
The subject area embraced by the term "biological control" in its classical sense is very broad indeed. The term itself was apparently first used in 1919 by the late Harry S. Smith, and was then used specifically in reference to the suppression of insect populations by the actions of their indigenous or introduced natural enemies. The California school of biological control specialists who followed in Smith's footsteps have traditionally differentiated "natural" biological control (by indigenous natural enemies) and "applied" biological control (by man-introduced natural enemies). Subsequently, the philosophy broadened beyond the original narrow concern with population suppression of insects (and especially pest insects), to embrace directed activities against mites or other arthropod pests, various invertebrate and vertebrate pests, weeds, and organisms producing disease in humans or their domestic animals and plants. The techniques used in these activities also multiplied beyond the original concern with natural enemies. The subjects area discussed in this book is, at the same time, broader and more restricted than that covered in other books on "biological control. " On the one hand, the treatment here is restrictive in that, with rare exception, we have limited ourselves to dealing only with ideas and examples involving the suppression of insect pests through human activity or intervention in the environment.

H.C. Erik Midelfort has carved out a reputation for innovative work on early modern German history, with a particular focus on the social history of ideas and religion. This collection pulls together some of his best work on the related subjects of witchcraft, the history of madness and psychology, demonology, exorcism, and the social history of religious change in early modern Europe. Several of the pieces reprinted here constitute reviews of recent scholarly literature on their topics, while others offer sharp departures from conventional wisdom. A critique of Michel Foucault’s view of the history of madness proved both stimulating but irritating to Foucault’s most faithful readers, so it is reprinted here along with a short retrospective comment by the author. Another focus of this collection is the social history of the Holy Roman Empire, where towns, peasants, and noble families developed different perceptions of the Protestant and Catholic Reformations and of the options the religious revolutions of the sixteenth century offered. Finally, this collection also brings together articles which show how Freudian psychoanalysis and academic sociology have filtered and interpreted the history of early modern Germany.
