Unwanted childlessness affects approximately one in six couples worldwide. - though the exact proportion of the predominant cause of the problem remains controversial, according to the World Health Organization (WHO), in nearly 40% of cases the cause can be attributed to the female, in 20% to the male, in 25% to both, and in 15% the cause remains unknown. Based on these ?gures, the - cidence of male factor infertility in the general population is approximately 7%. The majority of these men, approximately 30%, experience irreversible idiopathic infertility and cannot father children without some form of medical intervention. Male factor infertility, in addition, may be caused by testicular germ cell cancer, which is known to represent the most common cancer among young men, aged 15 to 35 years, in Western industrialized countries. The number of affected men has increased dramatically over the past 50 years. There is now growing evidence that human testicular germ cell cancer originates from fetal germ cells exhibiting an aberrant programme of gene expression, and tumour progression may be favoured by an aberrant Sertoli cell-germ cell communication.
More than 80 personalities, in or from Germany, that over the centuries have shaped the development of analytical chemistry are introduced by brief biographies. These accounts go beyond summarising key biographical information and outline the individual's contributions to analytical chemistry. This richly illustrated Brief offers a unique resource of information that is not available elsewhere.
In the 21st century, digitalization is a global challenge of mankind. Even for the public, it is obvious that our world is increasingly dominated by powerful algorithms and big data. But, how computable is our world? Some people believe that successful problem solving in science, technology, and economies only depends on fast algorithms and data mining. Chances and risks are often not understood, because the foundations of algorithms and information systems are not studied rigorously. Actually, they are deeply rooted in logics, mathematics, computer science and philosophy.Therefore, this book studies the foundations of mathematics, computer science, and philosophy, in order to guarantee security and reliability of the knowledge by constructive proofs, proof mining and program extraction. We start with the basics of computability theory, proof theory, and information theory. In a second step, we introduce new concepts of information and computing systems, in order to overcome the gap between the digital world of logical programming and the analog world of real computing in mathematics and science. The book also considers consequences for digital and analog physics, computational neuroscience, financial mathematics, and the Internet of Things (IoT).
The Antarctic is one the most hostile natural environments in the world. It is an extraordinary physical space, which changes significantly in shape and size with the passing of the seasons. Politically, it is unique as it contains one of the few areas of continental space not claimed by any nation-state. Scientifically, the continental ice sheet has provided us with vital evidence about the Earth's past climate. In this Very Short Introduction, Klaus Dodds provides a modern account of Antarctica, highlighting the main issues facing the continent today. Looking at how the Antarctic has been explored and represented in the last hundred years, Dodds considers the main exploratory and scientific achievements of the region. He explains how processes such as globalization mean that the Antarctic is increasingly involved in a wider circuit of ideas, goods, people, trade, and governance - all of which have an impact on the future of the region. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
This second volume of The Churches and the Third Reich, the last which the author lived to write, covers the year 1934. This year, which saw the birth of the Confessing Church and the great Synods of Barmen and Dahlem, was the year of disillusionment, in which all the hopes of 1933 were shattered one by one. The gripping narrative of the first volume is continued as in addition to the rise of a legitimate church opposition we see how the German Christians overreached themselves by seeking, without Hitler’s approval and against the law, to set up a Reich Church fully coordinated with the state. Meanwhile, the Roman Catholic Church was running into increasing difficulties as it tried to cope with the problems left unresolved on the conclusion of the Concordat. Like the first, this volume has many illustrations.
Geopolitics is a way of looking at the world. Using wide-ranging examples, from historical maps to James Bond films and the rhetoric of political leaders like Churchill and George W. Bush, this title shows why, for a full understanding of contemporary global politics, it is essential to be geopolitical.
This World War II memoir by a Nazi soldier details his unimaginable experience as a German prisoner-of-war in the Soviet Union. Lothar Hermann grew up in Bavaria, going through the RAD (Nazi Labor Service) before being conscripted into a Wehrmacht Mountain Division (the Gebirgsdivision) in 1940. He participated in Germany’s advance through southern Ukraine in 1941 and, in 1944, was arrested in Romania while retreating to Germany. The Romanians passed him onto the Soviets, who placed him in a forced labor camp, where he watched two-thirds of prisoners around him die. In 1949, Herrmann was finally released to Germany and returned to Bavaria. Three million German troops were taken prisoner by the Red Army and around two-thirds of them survived to return to Germany in 1949 like Hermann, but their stories are little known. Klaus Willmann draws on interviews he conducted with Herrmann, to recount these astonishing recollections in the first-person. Depicting the challenges of growing up in Nazi Bavaria to becoming a Soviet prisoner-of-war, this is a gripping and enlightening account from a necessary but rarely explored perspective.
Software product lines represent perhaps the most exciting paradigm shift in software development since the advent of high-level programming languages. Nowhere else in software engineering have we seen such breathtaking improvements in cost, quality, time to market, and developer productivity, often registering in the order-of-magnitude range. Here, the authors combine academic research results with real-world industrial experiences, thus presenting a broad view on product line engineering so that both managers and technical specialists will benefit from exposure to this work. They capture the wealth of knowledge that eight companies have gathered during the introduction of the software product line engineering approach in their daily practice.
Very Short Introductions: Brilliant, Sharp, Inspiring The Arctic is demanding global attention. It is warming, melting, and thawing in a manner that threatens fundamental state-change. For communities that call the Arctic 'home' this is unwelcome. A warming Arctic brings with it the spectre of costly disruption and interference in indigenous lives and communal welfare. For others, the disappearance of sea ice makes the Arctic appear more accessible and less remote. This also brings with it dangers such as the prospect of a new era of great power rivalries involving China, Russia, and the United States. Submarine and long-range bomber patrolling are now commonplace. New terms such as 'global Arctic' are being used to capture the dynamic of change while others muse about the 'return of a Cold War'. The reality is inevitably more complex. The physical geography of the Arctic is highly varied and variable. Environmental change brings opportunities for indigenous and non-indigenous life-forms to survive and even thrive. The Arctic's four million people are not helpless pawns in a game of global geopolitics. The Arctic is not only a resource hotspot but also a place where sustainable energy systems are being introduced. A warming Arctic with less ice and permafrost is not unique in the longer history of the Earth either. The Arctic is a complex space. In this Very Short Introduction, Klaus Dodds and Jamie Woodward consider the major dimensions of the region and the linkages beyond - from the geopolitical to the environmental. They examine the causes, drivers, and effects of cultural, physical, political, and economic change, and ponder the future of the Arctic. As they show, it is a future which will affect us all.

Employing thematic investigation and illustrated through case studies, Dodds explores how global politics is imagined and practised by countries such as the US and other organisations including Greenpeace, the IMF and CNN International. In addition, the author discusses how issues such as environmental degradation, terror networks, anti-globalisation protests and North-South relations challenge, consolidate and subvert the existing international political system.
Automation and Its Macroeconomic Consequences reveals new ways to understand the economic characteristics of our increasing dependence on machines. Illuminating technical and social elements, it describes economic policies that could counteract negative income distribution consequences of automation without hampering the adoption of new technologies. Arguing that modern automation cannot be compared to the Industrial Revolution, it considers consequences of automation such as spatial patterns, urbanization, and regional concerns. In touching upon labor, growth, demographic, and policy, Automation and its Macroeconomic Consequences stands at the intersection of technology and economics, offering a comprehensive portrait illustrated by empirical observations and examples. - Introduces formal growth models that include automation and the empirical specifications on which the data-driven results rely - Focuses on formal modeling, empirical analysis and derivation of evidence-based policy conclusions - Considers consequences of automation, such as spatial patterns, urbanization and regional concerns
This new up-to-date edition of the successful handbook and ready reference retains the proven concept of the first, covering basic and advanced methods and applications in infrared imaging from two leading expert authors in the field. All chapters have been completely revised and expanded and a new chapter has been added to reflect recent developments in the field and report on the progress made within the last decade. In addition there is now an even stronger focus on real-life examples, with 20% more case studies taken from science and industry. For ease of comprehension the text is backed by more than 590 images which include graphic visualizations and more than 300 infrared thermography figures. The latter include many new ones depicting, for example, spectacular views of phenomena in nature, sports, and daily life.
This volume provides a comprehensive introduction to the theory of (deterministic) optimization. It covers both continuous and discrete optimization. This allows readers to study problems under different points-of-view, which supports a better understanding of the entire field. Many exercises are included to increase the reader's understanding.
Everybody knows them. Smartphones that talk to us, wristwatches that record our health data, workflows that organize themselves automatically, cars, airplanes and drones that control themselves, traffic and energy systems with autonomous logistics or robots that explore distant planets are technical examples of a networked world of intelligent systems. Machine learning is dramatically changing our civilization. We rely more and more on efficient algorithms, because otherwise we will not be able to cope with the complexity of our civilizing infrastructure. But how secure are AI algorithms? This challenge is taken up in the 2nd edition: Complex neural networks are fed and trained with huge amounts of data (big data). The number of necessary parameters explodes exponentially. Nobody knows exactly what is going on in these "black boxes". In machine learning we need more explainability and accountability of causes and effects in order to be able to decide ethical and legal questions of responsibility (e.g. in autonomous driving or medicine)! Besides causal learning, we also analyze procedures of tests and verification to get certified AI-programs. Since its inception, AI research has been associated with great visions of the future of mankind. It is already a key technology that will decide the global competition of social systems. "Artificial Intelligence and Responsibility" is another central supplement to the 2nd edition: How should we secure our individual liberty rights in the AI world? This book is a plea for technology design: AI must prove itself as a service in society.
About this book: Inspired by Nassim N. Taleb's works The Black Swan, Antifragile, and Skin in the Game, Klaus Grobys explores how rationality and irrationality are manifested in human behavior across various domains of human life. The stories discussed in this book are based on real-life observations. This work deals with political incorrectness, the presence of concentration in virtually all domains of human life, the carelessness of industries manifested in profit-maximizing at the expense of simple folks, and various other issues that many authors typically avoid. The objective of this book is first to acquaint the reader with a new perspective concerning the concept of rationality and second to equip the reader to identify traps set up by profit-maximizing industries and self-serving lobbies.
A project is a unique undertaking or endeavor to be accomplished that can be divided into individual subtasks or activities each of which requires time and scarce resources for its completion. Also there is a desired objective to be attained (for example, minimization of project duration or of variation of resource utilization, or maximization of net present value of the project). Moreover, there are given precedence relationships among activities prescrib ing the order in which activities must be carried out. Project scheduling, in its basic form, consists of finding start times for all activities such that pre scribed resource and precedence constraints are satisfied and an objective function is optimized. Since the concept of a project can be interpreted quite broadly, project scheduling problems arise in a great variety of practical situations. These in clude construction work, the development and introduction of new products, service systems, or software packages, strategic long-term planning in manu facturing and the service sector, emergency planning, and even the conduct ing of political campaigns. Recently, project scheduling has been successfully applied to production and operations management, e.g. make-to-order pro duction in manufacturing and batch production in process industries. Since the late 1950's, network-based planning methods for project sched uling problems have been developed, cf. Elmaghraby (1977) and Moder et al.
Geopolitics is a slippery term. From great power politics and speculation about resource scrambles, to everyday encounters and objects such as smart phones, it affects citizens, corporations, international bodies, social movements, and governments. Geopolitics is far more than simply the impact of geographical features such as rivers, mountains, and climate on political developments. Geography matters but not necessarily in the way that pundits and presidents assume. In this Very Short Introduction, Klaus Dodds tours the field of geopolitics, encompassing both its intellectual historical origins and its current concerns. As people struggle to cross borders, moving a few feet either side of a territorial boundary can be a matter of life or death, dramatically highlighting the connections between place and politics. Even far away from the front lines of states, geopolitics remains an important part of everyday life. A country's connectivity, location, size, and resources all affect how the people that live there understand and interact with the wider world. In this third edition Dodds includes new sections considering the rise of populism and economic nationalism as examples of how states, people, and corporations manage territorial frames for political projects such as Make America Great Again, One Belt, One Road, and Brexit.
