Book Description
Complex networks datasets often come with the problem of missing information: interactions data that have not been measured or discovered, may be affected by errors, or are simply hidden because of privacy issues. This Element provides an overview of the ideas, methods and techniques to deal with this problem and that together define the field of network reconstruction. Given the extent of the subject, the authors focus on the inference methods rooted in statistical physics and information theory. The discussion is organized according to the different scales of the reconstruction task, that is, whether the goal is to reconstruct the macroscopic structure of the network, to infer its mesoscale properties, or to predict the individual microscopic connections.

Book Description
Evolution is a complex process, acting at multiple scales, from DNA sequences and proteins to populations of species. Understanding and reconstructing evolution is of major importance in numerous subfields of biology. For example, phylogenetics and sequence evolution is central to comparative genomics, attempts to decipher genomes, and molecular epidemiology. Phylogenetics is also the focal point of large-scale international biodiversity assessment initiatives such as the 'Tree of Life' project, which aims to build the evolutionary tree for all extant species. Since the pioneering work in phylogenetics in the 1960s, models have become increasingly sophisticated to account for the inherent complexity of evolution. They rely heavily on mathematics and aim at modelling and analyzing biological phenomena such as horizontal gene transfer, heterogeneity of mutation, and speciation and extinction processes. This book presents these recent models, their biological relevance, their mathematical basis, their properties, and the algorithms to infer them from data. A number of subfields from mathematics and computer science are involved: combinatorics, graph theory, stringology, probabilistic and Markov models, information theory, statistical inference, Monte Carlo methods, continuous and discrete algorithmics. This book arises from the Mathematics of Evolution & Phylogenetics meeting at the Mathematical Institute Henri Poincaré, Paris, in June 2005 and is based on the outstanding state-of-the-art reports presented by the conference speakers. Ten chapters - based around five themes - provide a detailed overview of key topics, from the underlying concepts to the latest results, some of which are at the forefront of current research.

Book Description
To document the world's diversity of species and reconstruct the tree of life we need to undertake some simple but mountainous tasks. Most importantly, we need to tackle species rich groups. We need to collect, name, and classify them, and then position them on the tree of life. We need to do this systematically across all groups of organisms and b

Book Description
Focusing on language contact involving Russian, and the linguistic varieties that emerged from that contact in different social settings, this book analyzes issues and methodologies in reconstructing both the linguistic effects of language contact and the social contexts of usage. In-depth analyses of Odessan Russian, a southern Russian contact variety with Yiddish and Ukrainian elements, and Russian lexifier pidgins illustrate the reconstruction process, which involves making the most of all available documentation, particularly literature and stereotypical descriptions. Historical sociolinguistics of this kind straddles the fields of historical linguistics, sociolinguistics, and contact; this book brings together the methods and theories of these areas to show how they can result in a rich reconstruction of linguistic and socially-conditioned variation. We reconstruct the circumstances and social settings that produced this variation, and demonstrate how to reconstruct which variants were used by different types of speakers under different circumstances, and what kinds of social identities they indexed.

Book Description
The main subject of this publication is the co-creation of society and biotechnology. The authors do not treat society and biotechnology as separate domains, instead they consider technologies as socially constructed. The main focus of this publication is on agro-biotechnologies and the contributors present perspectives for reconstruction both from and in 'the North' and 'the South'. Reconstructing biotechnologies offers a range of critical social analyses confronting the actuality of biotechnology with the potentialities of its social reconstruction. In doing that, the book develops and merges literature from four different disciplines, namely (i) critical theory and its analyses of technology and power, (ii) political economy, critically assessing the interrelationship between economy, politics and technology, (iii) social constructivism, which holds that technology is the product of agency and knowledge systems, and (iv) the analysis of rural society and agrarian technologies in rural sociology. Reconstructing biotechnologies introduces exciting approaches and examples into the social reshaping of biotechnologies. It brings together critical examinations of contemporary biotechnology development and puts forward possible alternatives written by critical scholars. The contributions in this publication are for students and scholars in a wide range of disciplines such as social and political sciences, science and technology studies, and development studies. The editors of the book are associated with the Social Sciences Department of Wageningen University in the Netherlands and the Graduate School of Economics of Kyoto University in Japan. They have published extensively on social and political theory and biotechnology.

Book Description
Network research has recently been adopted as one of the tools of the trade in archaeology, used to study a wide range of topics: interactions between island communities, movements through urban spaces, visibility in past landscapes, material culture similarity, exchange, and much more. This Handbook is the first authoritative reference work for archaeological network research, featuring current topical trends and covering the archaeological application of network methods and theories. This is elaborately demonstrated through substantive topics and case studies drawn from a breadth of periods and cultures in world archaeology. It highlights and further develops the unique contributions made by archaeological research to network science, especially concerning the development of spatial and material culture network methods and approaches to studying long-term network change. This is the go-to resource for students and scholars wishing to explore how network science can be applied in archaeology through an up-to-date overview of the field.

Book Description
Big data, genomics, and quantitative approaches to network-based analysis are combining to advance the frontiers of medicine as never before. Network Medicine introduces this rapidly evolving field of medical research, which promises to revolutionize the diagnosis and treatment of human diseases. With contributions from leading experts that highlight the necessity of a team-based approach in network medicine, this definitive volume provides readers with a state-of-the-art synthesis of the progress being made and the challenges that remain. Medical researchers have long sought to identify single molecular defects that cause diseases, with the goal of developing silver-bullet therapies to treat them. But this paradigm overlooks the inherent complexity of human diseases and has often led to treatments that are inadequate or fraught with adverse side effects. Rather than trying to force disease pathogenesis into a reductionist model, network medicine embraces the complexity of multiple influences on disease and relies on many different types of networks: from the cellular-molecular level of protein-protein interactions to correlational studies of gene expression in biological samples. The authors offer a systematic approach to understanding complex diseases while explaining network medicine’s unique features, including the application of modern genomics technologies, biostatistics and bioinformatics, and dynamic systems analysis of complex molecular networks in an integrative context. By developing techniques and technologies that comprehensively assess genetic variation, cellular metabolism, and protein function, network medicine is opening up new vistas for uncovering causes and identifying cures of disease.

Book Description
Published in 1999. Originally published in 1981, Control and Power in Central-Local Government Relations set out to provide a re-interpretation of central-local relations in Britain. The book reviewed the (then) existing literature; redefined the subject of intergovernmental relations (IGR); and developed a theory linking IGR to broader issues in the study of British Government. It rapidly became a classic in the study of local government. The link to broader issues what achieved through the power-dependence model and the focus on policy communities. The book underpinned the vast growth in the study of policy networks in British government. This revised edition includes four new chapters, two of which have been specially written. The new Preface traces the fortunes of the power-dependence model, commenting on and updating the individual chapters. A new part II continues the story. It contains a 1986 essay reviewing criticism of the original model (chapter 6); a 1992 article discussing unresolved issues in the study of policy networks (chapter 7); and a new chapter assessing where we are now in the study of networks. It argues, provocatively, for an ethnographic focus on traditions and narratives; on how individuals construct networks. The book remains essential reading for all students and academics concerned with the study of IGR and policy networks.
