Download or read book Complex Spreading Phenomena in Social Systems written by Sune Lehmann and published by Springer. This book was released on 2018-06-21 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text is about spreading of information and influence in complex networks. Although previously considered similar and modeled in parallel approaches, there is now experimental evidence that epidemic and social spreading work in subtly different ways. While previously explored through modeling, there is currently an explosion of work on revealing the mechanisms underlying complex contagion based on big data and data-driven approaches. This volume consists of four parts. Part 1 is an Introduction, providing an accessible summary of the state of the art. Part 2 provides an overview of the central theoretical developments in the field. Part 3 describes the empirical work on observing spreading processes in real-world networks. Finally, Part 4 goes into detail with recent and exciting new developments: dedicated studies designed to measure specific aspects of the spreading processes, often using randomized control trials to isolate the network effect from confounders, such as homophily. Each contribution is authored by leading experts in the field. This volume, though based on technical selections of the most important results on complex spreading, remains quite accessible to the newly interested. The main benefit to the reader is that the topics are carefully structured to take the novice to the level of expert on the topic of social spreading processes. This book will be of great importance to a wide field: from researchers in physics, computer science, and sociology to professionals in public policy and public health.
Download or read book How Behavior Spreads written by Damon Centola and published by Princeton University Press. This book was released on 2020-03-24 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new, counterintuitive theory for how social networks influence the spread of behavior New social movements, technologies, and public-health initiatives often struggle to take off, yet many diseases disperse rapidly without issue. Can the lessons learned from the viral diffusion of diseases improve the spread of beneficial behaviors and innovations? How Behavior Spreads presents over a decade of original research examining how changes in societal behavior—in voting, health, technology, and finance—occur and the ways social networks can be used to influence how they propagate. Damon Centola's startling findings show that the same conditions that accelerate the viral expansion of an epidemic unexpectedly inhibit the spread of behaviors. How Behavior Spreads is a must-read for anyone interested in how the theory of social networks can transform our world.

Available in PDF, EPUB and Kindle. Book excerpt: This work improves the applicability of complex contagion theory to empirical data by examining the assumptions of previous models of complex contagion and developing methods for measuring theoretically relevant quantities from observational data. I consider the dynamics of complex contagion processes on networks with different distributions of tie range. Following prior work, I explore the impact of permuting networks to induce more long range ties but also examine the contagion motifs and larger scale dynamics observed during the contagion life-cycle. I identify a mechanism-the formation of persistent locally isolated clusters-that triggers sudden mid-life-cycle increases in the rate of contagion on networks with some long range ties. I argue that both the number and the distribution of long range ties is critical to development of such clusters. A survey of tie range distributions in empirical social networks revealed a consistent qualitative pattern where the range of long range ties is decidedly shorter than previous complex contagion models assumed. Next, I examine contagion dynamics on networks with more realistic distributions of tie range. Even though the neighborhood-to-node contagion motifs are substantially the same on both types of networks, realistic tie range distributions virtually eliminate the endogenous development of the clusters. Contagion on these networks is more robust to permutation but does not produce the mid-cycle accelerations found in networks with uniformly random permu- tation. Finally, I identify a measurement issue that biases estimates of node thresholds from observed exposure at activation. I show the bias can be reduced by collecting additional data about non-activating exposures and using only a subset of observations to produce the estimates. The empirically informed models presented in this work provide new insight about the potential outcome and dynamics of complex contagion processes in human social networks. Improved estimation techniques for node thresholds allow particular cases of empirical contagion to be described in terms of complex contagion theory. The results support an ongoing research program in complex contagion.
Download or read book Networks Crowds and Markets written by David Easley and published by Cambridge University Press. This book was released on 2010-07-19 with total page 745 pages. Available in PDF, EPUB and Kindle. Book excerpt: Are all film stars linked to Kevin Bacon? Why do the stock markets rise and fall sharply on the strength of a vague rumour? How does gossip spread so quickly? Are we all related through six degrees of separation? There is a growing awareness of the complex networks that pervade modern society. We see them in the rapid growth of the internet, the ease of global communication, the swift spread of news and information, and in the way epidemics and financial crises develop with startling speed and intensity. This introductory book on the new science of networks takes an interdisciplinary approach, using economics, sociology, computing, information science and applied mathematics to address fundamental questions about the links that connect us, and the ways that our decisions can have consequences for others.
Download or read book Change written by Damon Centola and published by Little, Brown Spark. This book was released on 2021-01-19 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: How to create the change you want to see in the world using the paradigm-busting ideas in this "utterly fascinating" (Adam Grant) big-idea book. Most of what we know about how ideas spread comes from bestselling authors who give us a compelling picture of a world, in which "influencers" are king, "sticky" ideas "go viral," and good behavior is "nudged" forward. The problem is that the world they describe is a world where information spreads, but beliefs and behaviors stay the same. When it comes to lasting change in what we think or the way we live, the dynamics are different: beliefs and behaviors are not transmitted from person to person in the simple way that a virus is. The real story of social change is more complex. When we are exposed to a new idea, our social networks guide our responses in striking and surprising ways. Drawing on deep-yet-accessible research and fascinating examples from the spread of coronavirus to the success of the Black Lives Matter movement, the failure of Google+, and the rise of political polarization, Change presents groundbreaking and paradigm-shifting new science for understanding what drives change, and how we can change the world around us.

Available in PDF, EPUB and Kindle. Book excerpt: An Observer Book of the Year A Times Science Book of the Year A New Statesman Book of the Year A Financial Times Science Book of the Year 'Astonishingly bold' Daily Mail 'It is hard to imagine a more timely book ... much of the modern world will make more sense having read it.' The Times We live in a world that's more interconnected than ever before. Our lives are shaped by outbreaks - of disease, of misinformation, even of violence - that appear, spread and fade away with bewildering speed. To understand them, we need to learn the hidden laws that govern them. From 'superspreaders' who might spark a pandemic or bring down a financial system to the social dynamics that make loneliness catch on, The Rules of Contagion offers compelling insights into human behaviour and explains how we can get better at predicting what happens next. Along the way, Adam Kucharski explores how innovations spread through friendship networks, what links computer viruses with folk stories - and why the most useful predictions aren't necessarily the ones that come true. Now revised and updated with content on Covid-19.
Download or read book Animal Social Networks written by Dr. Jens Krause and published by Oxford University Press. This book was released on 2015 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scientific study of networks - computer, social, and biological - has received an enormous amount of interest in recent years. However, the network approach has been applied to the field of animal behaviour relatively late compared to many other biological disciplines. Understanding social network structure is of great importance for biologists since the structural characteristics of any network will affect its constituent members and influence a range of diverse behaviours. These include finding and choosing a sexual partner, developing and maintaining cooperative relationships, and engaging in foraging and anti-predator behavior. This novel text provides an overview of the insights that network analysis has provided into major biological processes, and how it has enhanced our understanding of the social organisation of several important taxonomic groups. It brings together researchers from a wide range of disciplines with the aim of providing both an overview of the power of the network approach for understanding patterns and process in animal populations, as well as outlining how current methodological constraints and challenges can be overcome. Animal Social Networks is principally aimed at graduate level students and researchers in the fields of ecology, zoology, animal behaviour, and evolutionary biology but will also be of interest to social scientists.

Download or read book Middle Leadership Mastery written by Adam Robbins and published by Crown House Publishing Ltd. This book was released on 2021-05-26 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: To make the best decisions possible, middle leaders need to have a nuanced understanding of the consequences of their actions. In this pragmatic book, Adam Robbins aims to boost their role-specific expertise to help them achieve that goal - and offers them a preferable alternative to learning from their mistakes. Instead of relying on generic leadership theories, Middle Leadership Mastery collates perspectives from psychology and cognitive science to share evidence-informed guidance on a wide range of topics - from supporting staff and students in crisis and managing wellbeing, to quality-assuring teaching and curriculum design. Adam Robbins draws on his sixteen years' experience of teaching in a deprived area to illustrate his points with stories and anecdotes from the front line, demonstrating how middle leaders can better understand their context and deliver the best outcomes from a variety of starting points.
Download or read book Contagion Systemic Risk in Financial Networks written by T. R. Hurd and published by Springer. This book was released on 2016-05-25 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a unified mathematical framework for the transmission channels for damaging shocks that can lead to instability in financial systems. As the title suggests, financial contagion is analogous to the spread of disease, and damaging financial crises may be better understood by bringing to bear ideas from studying other complex systems in our world. After considering how people have viewed financial crises and systemic risk in the past, it delves into the mechanics of the interactions between banking counterparties. It finds a common mathematical structure for types of crises that proceed through cascade mappings that approach a cascade equilibrium. Later chapters follow this theme, starting from the underlying random skeleton graph, developing into the theory of bootstrap percolation, ultimately leading to techniques that can determine the large scale nature of contagious financial cascades.

Download or read book Contagion of Violence written by National Research Council and published by National Academies Press. This book was released on 2013-03-06 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past 25 years have seen a major paradigm shift in the field of violence prevention, from the assumption that violence is inevitable to the recognition that violence is preventable. Part of this shift has occurred in thinking about why violence occurs, and where intervention points might lie. In exploring the occurrence of violence, researchers have recognized the tendency for violent acts to cluster, to spread from place to place, and to mutate from one type to another. Furthermore, violent acts are often preceded or followed by other violent acts. In the field of public health, such a process has also been seen in the infectious disease model, in which an agent or vector initiates a specific biological pathway leading to symptoms of disease and infectivity. The agent transmits from individual to individual, and levels of the disease in the population above the baseline constitute an epidemic. Although violence does not have a readily observable biological agent as an initiator, it can follow similar epidemiological pathways. On April 30-May 1, 2012, the Institute of Medicine (IOM) Forum on Global Violence Prevention convened a workshop to explore the contagious nature of violence. Part of the Forum's mandate is to engage in multisectoral, multidirectional dialogue that explores crosscutting, evidence-based approaches to violence prevention, and the Forum has convened four workshops to this point exploring various elements of violence prevention. The workshops are designed to examine such approaches from multiple perspectives and at multiple levels of society. In particular, the workshop on the contagion of violence focused on exploring the epidemiology of the contagion, describing possible processes and mechanisms by which violence is transmitted, examining how contextual factors mitigate or exacerbate the issue. Contagion of Violence: Workshop Summary covers the major topics that arose during the 2-day workshop. It is organized by important elements of the infectious disease model so as to present the contagion of violence in a larger context and in a more compelling and comprehensive way.

Available in PDF, EPUB and Kindle. Book excerpt: This research monograph provides the means to learn the theory and practice of graph and network analysis using the Python programming language. The social network analysis techniques, included, will help readers to efficiently analyze social data from Twitter, Facebook, LiveJournal, GitHub and many others at three levels of depth: ego, group, and community. They will be able to analyse militant and revolutionary networks and candidate networks during elections. For instance, they will learn how the Ebola virus spread through communities. Practically, the book is suitable for courses on social network analysis in all disciplines that use social methodology. In the study of social networks, social network analysis makes an interesting interdisciplinary research area, where computer scientists and sociologists bring their competence to a level that will enable them to meet the challenges of this fast-developing field. Computer scientists have the knowledge to parse and process data while sociologists have the experience that is required for efficient data editing and interpretation. Social network analysis has successfully been applied in different fields such as health, cyber security, business, animal social networks, information retrieval, and communications.
