This book describes how powerful computing technology, emerging big and open data sources, and theoretical perspectives on spatial synthesis have… revolutionized the way in which we investigate social sciences and humanities. It summarizes the principles and applications of human-centered computing and spatial social science and humanities research, thereby providing fundamental information that will help shape future research. The book illustrates how big spatiotemporal socioeconomic data facilitate the modelling of individuals’ economic behavior in space and time and how the outcomes of such models can reveal information about economic trends across spatial scales. It describes how spatial social science and humanities research has shifted from a data-scarce to a data-rich environment. The chapters also describe how a powerful analytical framework for identifying space-time research gaps and frontiers is fundamental to comparative study of spatiotemporal phenomena, and how research topics have evolved from structure and function to dynamic and predictive. As such this book provides an interesting read for researchers, students and all those interested in computational and spatial social sciences and humanities.

Der Boden unter unseren Füßen erscheint uns unwandelbar und fest. Aber der Eindruck täuscht. Denn in Wirklichkeit ist die Erdkruste… alles andere als unbeweglich und verlässlich. So sind die Kontinente immer in Bewegung, Gebirge wachsen in den Himmel, Gesteine bilden sich neu und Meeresböden dehnen sich aus. Doch die Plattentektonik ist nur eines von vielen geologischen Phänomenen, die ihren Ursprung tief im Erdinneren haben. Um zu ergründen, wie unser Planet tickt, haben Geowissenschaftler in den letzten Jahren fast schon eine Reise zum Mittelpunkt der Erde unternommen. Mithilfe von Satelliten, seismischen Wellen und komplexen Simulationen haben sie dabei viele überraschende und faszinierende Erkenntnisse gewonnen. Die Autoren stellen in ihrem Buch einige der wichtigsten Resultate dieser spannenden Detektivarbeit vor. So erklären sie beispielsweise, warum das wahre Gesicht der Erde eine Kartoffel ist oder wieso sich das Erdmagnetfeld viel launischer verhält als gemeinhin angenommen.
For the first time in a thousand years, Americans are experiencing a reversal in lifespan. Despite living in one of… the safest and most secure eras in human history, one in five adults suffers from anxiety as does one-third of adolescents. Nearly half of the US population is overweight or obese and one-third of Americans suffer from chronic pain – the highest level in the world. In the United States, fatalities due to prescription pain medications now surpass those of heroin and cocaine combined, and each year 10% of all students on American college campuses contemplate suicide. With the proliferation of social media and the algorithms for social sharing that prey upon our emotional brains, inaccurate or misleading health articles and videos now move faster through social media networks than do reputable ones. This book is about modern health – or lack of it. The authors make two key arguments: that our deteriorating wellness is rapidly becoming a health emergency, and two, that much of these trends are rooted in the way our highly evolved hardwired brains and bodies deal with modern social change. The co-authors: a PhD from the world of social science and an MD from the world of medicine – combine forces to bring this emerging human crisis to light. Densely packed with fascinating facts and little-told stories, the authors weave together real-life cases that describe how our ancient evolutionary drives are propelling us toward ill health and disease. Over the course of seven chapters, the authors unlock the mysteries of our top health vices: why hospitals are more dangerous than warzones, our addiction to sugar, salt, and stress, our emotionally-driven brains, our relentless pursuit of happiness, our sleepless society, our understanding of risk, and finally, how world history can be a valuable tutor. Through these varied themes, the authors illustrate how our social lives are more of a determinant of health outcome than at any other time in our history, and to truly understand our plight, we need to recognize when our decisions and behavior are being directed by our survival-seeking hardwired brains and bodies.

This book highlights the existence of a diversity of methods in science, in general, in groups of sciences (natural, social or the… artificial), and in individual sciences. This methodological variety is open to a number of consequences, such as the differences in the research according to levels of reality (micro, meso and macro), which leads to multi-scale modelling and to questioning “fundamental” parts in the sciences, understood as the necessary support for the whole discipline. In addition, this volume acknowledges the need to assess the efficacy of procedures and methods of scientific activity in engendering high quality results in research made; the relevance of contextual factors for methodology of science; the existence of a plurality of stratagems when doing research in empirical sciences (natural, social and of the artificial); and the need for an ethical component while developing scientific methods, because values should have a role in scientific research. The book is of interest to a broad audience of philosophers, academics in various fields, graduate students and research centers interested in methodology of science.
This book presents new theoretical perspectives on ecological community dynamics and in so doing casts fresh light on the enduring… complexity–stability debate. Real ecological communities do not simply comprise diverse species and interactions, which respectively represented the nodes and links of the classic network theory. Rather, they are characterized by different types of complexity, and this book explains how this diversity of complexity is key to understanding the dynamics of ecological communities. It is shown how various properties in natural communities, such as life history, adaptation, density dependence, sex, interaction types, space, functional traits, and microbial processes, can dramatically increase the complexity in ecological communities. Furthermore, innovative methods are introduced that may be applied to cast light on very complex communities. With each chapter presenting the latest advances and approaches, the book sets the direction for future research on ecological community dynamics. It will be a “must read” for researchers and students in the field of ecology.
