Download or read book Collective Attention on the Web written by Christian Bauckhage and published by . This book was released on 2016-11-30 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the dynamics of collective human attention has been called a key scientific challenge for the information age. Tackling this challenge, Collective Attention on the Web explores the dynamics of collective attention related to Internet phenomena such as Internet memes, viral videos, or social media platforms and Web-based businesses. To this end, it analyzes time series data that directly or indirectly represent how the interest of large populations of Web users in content or services develops over time. Regardless of regional or cultural contexts, it generally observes strong regularities in time series that reflect attention dynamics and it discusses mathematical models that provide plausible explanations as to what drives the apparently dominant dynamics of rapid initial growth and prolonged decline.

Book Synopsis Collective Attention and the Dynamics of Group Deals by : Mao Ye
Download or read book Collective Attention and the Dynamics of Group Deals written by Mao Ye and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a study of the group purchasing behavior of daily deals in Groupon and LivingSocial and introduce a predictive dynamic model of collective attention for group buying behavior. In our model, the aggregate number of purchases at a given time comprises two types of processes: random discovery and social propagation. We find that these processes are very clearly separated by an inflection point. Using large data sets from both Groupon and LivingSocial we show how the model is able to predict the success of group deals as a function of time. We find that Groupon deals are easier to predict accurately earlier in the deal lifecycle than LivingSocial deals due to the final number of deal purchases saturating quicker. One possible explanation for this is that the incentive to socially propagate a deal is based on an individual threshold in LivingSocial whereas it is based on a collective threshold, which for the most part is reached very early on in Groupon. Furthermore, the personal benefit of propagating a deal is also greater in LivingSocial.

Available in PDF, EPUB and Kindle. Book excerpt: What is the symbolic impact of the Vietnam War Memorial? How does television change our engagement with the past? Can the efforts to wipe out Communist legacies succeed? Should victims of the Holocaust be celebrated as heroes or as martyrs? These questions have a great deal in common, yet they are typically asked separately by people working in distinct research areas in different disciplines. Frames of Remembrance shares ideas and concerns across such divides.
Book Synopsis Dynamics and Analysis of Alignment Models of Collective Behavior by : Roman Shvydkoy
Download or read book Dynamics and Analysis of Alignment Models of Collective Behavior written by Roman Shvydkoy and published by Springer Nature. This book was released on 2021-05-13 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces a class of alignment models based on the so-called Cucker-Smale system as well as its kinetic and hydrodynamic counterparts. Cutting edge research in the area of collective behavior is presented, including emerging techniques from fluid mechanics, fractional analysis, and kinetic theory. Analytical aspects are highlighted throughout, such as regularity theory and long time behavior of solutions. Featuring open problems, readers will be motivated to apply these breakthrough methods to future research. The chapters offer an overview of state of the art research with introductions to core concepts. Chapter One introduces the central focus of the book: The agent-based Cucker-Smale system. Further agent-based systems and alignment systems are covered in chapters Two and Three. Following this are chapters covering the kinetic and hydrodynamic variants of the Cucker-Smale system. The core well-posedness theory of both smooth and singular models is then presented. Chapter Eight discusses the fully developed one-dimensional theory. The final chapter presents some of the known partial results concerning the regularity of multidimensional Euler Alignment systems. Dynamics and Analysis of Alignment Models of Collective Behavior is ideal for graduate students and researchers studying PDEs, especially those interested in the active areas of collective behavior and alignment models.
Book Synopsis Social Acceleration by : Hartmut Rosa
Download or read book Social Acceleration written by Hartmut Rosa and published by Columbia University Press. This book was released on 2013-05-14 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hartmut Rosa advances an account of the temporal structure of society from the perspective of critical theory. He identifies in particular three categories of change in the tempo of modern social life: technological acceleration, evident in transportation, communication, and production; the acceleration of social change, reflected in cultural knowledge, social institutions, and personal relationships; and acceleration in the pace of life, which happens despite the expectation that technological change should increase an individual's free time. According to Rosa, both the structural and cultural aspects of our institutions and practices are marked by the "shrinking of the present," a decreasing time period during which expectations based on past experience reliably match future results and events. When this phenomenon combines with technological acceleration and the increasing pace of life, time seems to flow ever faster, making our relationships to each other and the world fluid and problematic. It is as if we are standing on "slipping slopes," a steep social terrain that is itself in motion and in turn demands faster lives and technology. As Rosa deftly shows, this self-reinforcing feedback loop fundamentally determines the character of modern life.
Book Synopsis Online Collective Attention by : Michael Vincent Arnold

Book excerpt: Unprecedented growth in digital information has transformed data in the social sciences from scarce to abundant. Social media in particular has created a new algorithmically mediated sociotechnical system, one where billions of daily communications influence our perspective on reality in poorly understood ways. Boosted by advances in high performance computing, natural language processing, and machine learning, the digital traces left behind by these electronic breadcrumbs hold immense promise for measuring collective attention and sentiment at the societal scale. In one study, using hurricane name mentions as a proxy for awareness. We find that the exogenous temporal dynamics are remarkably similar across storms, but that overall collective attention varies widely even among storms causing comparable deaths and damage. We construct `hurricane attention maps' and observe that hurricanes causing deaths on (or economic damage to) the continental United States generate substantially more attention in English language tweets than those that do not. We find that a hurricane's Saffir-Simpson wind scale category assignment is strongly associated with the amount of attention it receives. Higher category storms receive higher proportional increases of attention per proportional increases in number of deaths or dollars of damage, than lower category storms. The most damaging and deadly storms of the 2010s, Hurricanes Harvey and Maria, generated the most attention and were remembered the longest, respectively. On average, a category 5 storm receives 4.6 times more attention than a category 1 storm causing the same number of deaths and economic damage. In a second study, we explore using well curated, large-scale corpora of social media posts containing broad public opinion as an alternative data source to complement traditional surveys. While surveys are effective at collecting representative samples and are capable of achieving high accuracy, they can be both expensive to run and lag public opinion by up to a month. Both of these drawbacks could be overcome with a real-time, high volume data stream and fast analysis pipeline. A central challenge in orchestrating such a data pipeline is devising an effective method for rapidly selecting the best corpus of relevant documents for analysis. Querying with keywords alone often includes irrelevant documents that are not easily disambiguated with bag-of-words natural language processing methods. Here, we explore methods of corpus curation to filter irrelevant tweets using pre-trained transformer-based models, fine-tuned for our binary classification task on hand-labeled tweets. We are able to achieve F1 scores of up to 0.95. The low cost and high performance of fine-tuning such a model suggests that our approach could be of broad benefit as a pre-processing step for social media datasets with uncertain corpus boundaries. In a third chapter, I describe my contributions to nearly 2 dozen studies leveraging Twitter data to explore collective attention, sentiment, and language. These cover a range of topics including the COVID-19 pandemic, politicians and K-pop stars, public health, and social movements, demonstrating the broad value of social media data in interdisciplinary research.

Book Synopsis Not a Hopeless Case by : Halee Gray Scott
Download or read book Not a Hopeless Case written by Halee Gray Scott and published by Zondervan. This book was released on 2023-04-25 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is America the next missionary graveyard? Or is it ripe for spiritual revolution? The statistics seem grim. Every year, the decline of Christianity continues at a rapid pace, especially among young adults. Churches across the country are closing their doors, dying, or are being "adopted" by nearby larger churches. What is the story church leaders hear? We've lost the next generation. But this decline in religious affiliation has not made us less spiritual. Young adults are still asking questions that only faith (or religion) can fully answer. Questions are like seeds buried in the rich, dark soil of our hearts. Nurtured with oxygen and water, they unfold into that which they were meant to become. Absent these conditions, they wither in the dark. Those most resistant to Christianity are those whose questions did not receive oxygen in their faith communities while they were children and teenagers. Not a Hopeless Case is the story of questions, the questions of young adults about faith and spirituality--young adults who are lost and want to be found--and the questions of pastors who seek to find them.

Book Synopsis Decision Making and Problem Solving in Organizations: Assessing and Expanding the Carnegie Perspective by : Daniella Laureiro Martinez
Download or read book Decision Making and Problem Solving in Organizations: Assessing and Expanding the Carnegie Perspective written by Daniella Laureiro Martinez and published by Frontiers Media SA. This book was released on 2024-09-04 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the broader study of decision-making, the Carnegie perspective occupies a unique place. Initially developed by pioneering scholars such as Herbert Simon and James March, it views organizational decisions as resulting from the combined influences of a.) psychological processes of attention allocation, interpretation of experience, and motivated search, and b.) features of the organizational context that direct attention, influence preferences, contend with ambiguity, contain conflict, and divide labor. Despite its unique strengths and a considerable body of work (see below some foundational references), research that adopts the Carnegie perspective is still relatively unknown outside the field of organization studies. As James March noted, Carnegie has been primarily an importer of ideas, rather than an exporter. The goal of this research topic is to facilitate dialogue and integration between this well-established Carnegie perspective and other lines of inquiry into the study of decision making and problem solving. We are interested in bringing to the fore what is distinctive in the accumulated body of evidence produced by the Carnegie perspective and highlighting similarities, differences, and potential points of connection with other research done on similar topics. To achieve this goal, we hope that the front end of each submission will cover the following four components:
Book Synopsis Controversy Mapping by : Tommaso Venturini
Download or read book Controversy Mapping written by Tommaso Venturini and published by John Wiley & Sons. This book was released on 2021-12-01 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: As disputes concerning the environment, the economy, and pandemics occupy public debate, we need to learn to navigate matters of public concern when facts are in doubt and expertise is contested. Controversy Mapping is the first book to introduce readers to the observation and representation of contested issues on digital media. Drawing on actor-network theory and digital methods, Venturini and Munk outline the conceptual underpinnings and the many tools and techniques of controversy mapping. They review its history in science and technology studies, discuss its methodological potential, and unfold its political implications. Through a range of cases and examples, they demonstrate how to chart actors and issues using digital fieldwork and computational techniques. A preface by Richard Rogers and an interview with Bruno Latour are also included. A crucial field guide and hands-on companion for the digital age, Controversy Mapping is an indispensable resource for students and scholars of media and communication, as well as activists, journalists, citizens, and decision makers.
Book Synopsis Dynamics of Nonlinear Time-Delay Systems by : Muthusamy Lakshmanan
Download or read book Dynamics of Nonlinear Time-Delay Systems written by Muthusamy Lakshmanan and published by Springer Science & Business Media. This book was released on 2011-01-04 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synchronization of chaotic systems, a patently nonlinear phenomenon, has emerged as a highly active interdisciplinary research topic at the interface of physics, biology, applied mathematics and engineering sciences. In this connection, time-delay systems described by delay differential equations have developed as particularly suitable tools for modeling specific dynamical systems. Indeed, time-delay is ubiquitous in many physical systems, for example due to finite switching speeds of amplifiers in electronic circuits, finite lengths of vehicles in traffic flows, finite signal propagation times in biological networks and circuits, and quite generally whenever memory effects are relevant. This monograph presents the basics of chaotic time-delay systems and their synchronization with an emphasis on the effects of time-delay feedback which give rise to new collective dynamics. Special attention is devoted to scalar chaotic/hyperchaotic time-delay systems, and some higher order models, occurring in different branches of science and technology as well as to the synchronization of their coupled versions. Last but not least, the presentation as a whole strives for a balance between the necessary mathematical description of the basics and the detailed presentation of real-world applications.

Book Synopsis Symbolic Power, Politics, and Intellectuals by : David L. Swartz
Download or read book Symbolic Power, Politics, and Intellectuals written by David L. Swartz and published by University of Chicago Press. This book was released on 2013-04-12 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power is the central organizing principle of all social life, from culture and education to stratification and taste. And there is no more prominent name in the analysis of power than that of noted sociologist Pierre Bourdieu. Throughout his career, Bourdieu challenged the commonly held view that symbolic power—the power to dominate—is solely symbolic. He emphasized that symbolic power helps create and maintain social hierarchies, which form the very bedrock of political life. By the time of his death in 2002, Bourdieu had become a leading public intellectual, and his argument about the more subtle and influential ways that cultural resources and symbolic categories prevail in power arrangements and practices had gained broad recognition. In Symbolic Power, Politics, and Intellectuals, David L. Swartz delves deeply into Bourdieu’s work to show how central—but often overlooked—power and politics are to an understanding of sociology. Arguing that power and politics stand at the core of Bourdieu’s sociology, Swartz illuminates Bourdieu’s political project for the social sciences, as well as Bourdieu’s own political activism, explaining how sociology is not just science but also a crucial form of political engagement.
