Available in PDF, EPUB and Kindle. Book excerpt: Interpretations of Plato, Stéphane Mallarmé, and Philippe Sollers’ writings in three essays: “Plato’s Pharmacy,” “The Double Session,” and “Dissemination.” “The English version of Dissemination [is] an able translation by Barbara Johnson . . . Derrida’s central contention is that language is haunted by dispersal, absence, loss, the risk of unmeaning, a risk which is starkly embodied in all writing. The distinction between philosophy and literature therefore becomes of secondary importance. Philosophy vainly attempts to control the irrecoverable dissemination of its own meaning, it strives—against the grain of language—to offer a sober revelation of truth. Literature—on the other hand—flaunts its own meretriciousness, abandons itself to the Dionysiac play of language. In Dissemination—more than any previous work—Derrida joins in the revelry, weaving a complex pattern of puns, verbal echoes and allusions, intended to ‘deconstruct’ both the pretension of criticism to tell the truth about literature, and the pretension of philosophy to the literature of truth.” —Peter Dews, The New Statesman

Book excerpt: Fifteen to twenty years is how long it takes for the billions of dollars of health-related research to translate into evidence-based policies and programs suitable for public use. Over the past 15 years, an exciting science has emerged that seeks to narrow the gap between the discovery of new knowledge and its application in public health, mental health, and health care settings. Dissemination and implementation (D & I) research seeks to understand how to best apply scientific advances in the real world, by focusing on pushing the evidence-based knowledge base out into routine use. To help propel this crucial field forward, leading D & I scholars and researchers have collaborated to put together this volume to address a number of key issues, including : how to evaluate the evidence base on effective interventions; which strategies will produce the greatest impact; how to design an appropriate study; and how to track a set of essential outcomes. D & I studies must also take into account the barriers to uptake of evidence-based interventions in the communities where people live their lives and the social service agencies, hospitals, and clinics where they receive care. The challenges of moving research to practice and policy are universal, and future progress calls for collaborative partnerships and cross-country research. The fundamental tenet of D & I research--taking what we know about improving health and putting it into practice--must be the highest priority. This book is nothing less than a roadmap that will have broad appeal to researchers and practitioners across many disciplines. [Ed.].

This book was released on 2020-05-14 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Social isolation and loneliness are serious yet underappreciated public health risks that affect a significant portion of the older adult population. Approximately one-quarter of community-dwelling Americans aged 65 and older are considered to be socially isolated, and a significant proportion of adults in the United States report feeling lonely. People who are 50 years of age or older are more likely to experience many of the risk factors that can cause or exacerbate social isolation or loneliness, such as living alone, the loss of family or friends, chronic illness, and sensory impairments. Over a life course, social isolation and loneliness may be episodic or chronic, depending upon an individual's circumstances and perceptions. A substantial body of evidence demonstrates that social isolation presents a major risk for premature mortality, comparable to other risk factors such as high blood pressure, smoking, or obesity. As older adults are particularly high-volume and high-frequency users of the health care system, there is an opportunity for health care professionals to identify, prevent, and mitigate the adverse health impacts of social isolation and loneliness in older adults. Social Isolation and Loneliness in Older Adults summarizes the evidence base and explores how social isolation and loneliness affect health and quality of life in adults aged 50 and older, particularly among low income, underserved, and vulnerable populations. This report makes recommendations specifically for clinical settings of health care to identify those who suffer the resultant negative health impacts of social isolation and loneliness and target interventions to improve their social conditions. Social Isolation and Loneliness in Older Adults considers clinical tools and methodologies, better education and training for the health care workforce, and dissemination and implementation that will be important for translating research into practice, especially as the evidence base for effective interventions continues to flourish.

Available in PDF, EPUB and Kindle. Book excerpt: This highly illuminating book marks a significant stage in our growing understanding of how the development of national traditions of economic thought has been affected by both internal and external factors. The expert contributors set an explicit agenda for the study of the dissemination of economic ideas across four centuries, acknowledging that the history of dissemination is also a history of the flux of economic beliefs, rendering any generalisation difficult, if not impossible. Topics explored include systems of political economy, European and American interactions, the diffusion of economic ideas in South-Eastern Europe and beyond, and the exchange of ideas between Japan and the rest of the world. This book will prove a fascinating and stimulating read for scholars and researchers in the field of economics generally, and more specifically in heterodox economics, the history of economic thought and economic theory.

This book was released on 2020-08-28 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recommendations for feeding infants and young children have changed substantially over time owing to scientific advances, cultural influences, societal trends, and other factors. At the same time, stronger approaches to reviewing and synthesizing scientific evidence have evolved, such that there are now established protocols for developing evidence-based health recommendations. However, not all authoritative bodies have used such approaches for developing infant feeding guidance, and for many feeding questions there is little or no sound evidence available to guide best practices, despite the fact that research on infant and young child feeding has expanded in recent decades. Summarizing the current landscape of feeding recommendations for infants and young children can reveal the level of consistency of existing guidance, shed light on the types of evidence that underpin each recommendation, and provide insight into the feasibility of harmonizing guidelines. Feeding Infants and Children from Birth to 24 Months collects, compares, and summarizes existing recommendations on what and how to feed infants and young children from birth to 24 months of age. This report makes recommendations to stakeholders on strategies for communicating and disseminating feeding recommendations.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers a diachronical and inter-/transmedia approach to the relationship of media and fear in a variety of geographical and cultural settings. This allows for an in-depth understanding of the media’s role in pandemics, wars and other crises, as well as in political intimidation. The book assembles chapters from a variety of authors, focusing on the relation between media and fear in the West, the Middle East, the Arab World and China. Besides its geographical and cultural diversity, the volume also takes a long-term perspective, bringing together cases from transforming media environments which span over a century. The book establishes a strong and historically persistent nexus between media and fear, which finds ever-new forms with new media but always follows similar logics.

Available in PDF, EPUB and Kindle. Book excerpt: “Cultural Graphology” could be the name of a new human science: this was Derrida’s speculation when, in the late 1960s, he imagined a discipline that combined psychoanalysis, deconstruction, and a commitment to the topic of writing. He never undertook the project himself but did leave two brief sketches of how he thought cultural graphology might proceed. In this book, Juliet Fleming picks up where Derrida left off. Using both his early and later thought, and the psychoanalytic texts to which it is addressed, to examine the print culture of early modern England, she drastically unsettles some key assumptions of book history. Fleming shows that the single most important lesson to survive from Derrida’s early work is that we do not know what writing is. Channeling Derrida’s thought into places it has not been seen before, she examines printed errors, spaces, and ornaments (topics that have hitherto been marginal to our accounts of print culture) and excavates the long-forgotten reading practice of cutting printed books. Proposing radical deformations to the meanings of fundamental and apparently simple terms such as “error,” “letter,” “surface,” and “cut,” Fleming opens up exciting new pathways into our understanding of writing all told.

Available in PDF, EPUB and Kindle. Book excerpt: If we push the definition of a?book? beyond the traditional form of the codex to encompass cuneiform tablets, papyri, as well as the printed and digital book- just what is the essence of its purpose? Featuring contributors from a wide range of disciplines such as art history, medieval studies, ancient Near-Eastern history, information management and the history of the book, this ambitious new release explores the biography of the concept of the book, and its function across millennia. 0The volume analyses the role of the book as a tool of communication. It examines a broad conceptual range; from the evolution of medieval encyclopaedia, 17th century pamphlets on witchcraft trials, and the role of books produced as propaganda by the Ministry of Information in Britain during the Second World War. It covers an impressive timespan and geography, detailing accounting systems in ancient Assyria, the dissemination of Aristotelian texts in late medieval Europe, and the Penny Post in 19th-century England. This volume boldly demonstrates the functionality of the book to be as diverse as human endeavour.

Book excerpt: Despite the existence of effective and economical psychological interventions for many mental disorders, the adoption of these treatments in service provision settings worldwide has lagged. A major gap persists between the development and identification of such interventions and their availability to the general public. Building upon the multidisciplinary literature on the science of dissemination and implementation, Dissemination and Implementation of Evidence-Based Psychological Interventions examines state-of-the-art programs to improve access to psychological interventions. Renowned experts describe leading efforts to facilitate the transport of evidence-based treatments, alongside innovative strategies for achieving the goals presented. Analyzing dissemination and implementation programs that range in aims and scope and include both national and local efforts, this book is divided into two parts. Chapters in Part I provide discussion of the history of evidence-based psychological interventions and the need for dissemination and implementation, an overview of the science of dissemination and implementation, and a review of the effectiveness of methods for clinician training. Chapters in Part II describe leading dissemination and implementation programs internationally, including the procedures and practices utilized and data on outcomes. The book concludes with a chapter by the volume's editors that proposes and discusses ten of the most important future directions for the science and practice of dissemination and implementation in mental health care. A crucial challenge in the field today is to translate the successes of treatment development research into the reduction of the public health burden of mental illness on individuals, families, and societies. This pioneering volume will be central to that effort and an essential resource for mental health practitioners and researchers, as well as decision-makers throughout the mental health care system.

This book was released on 2016-12-05 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern communications allow the instant dissemination of information and images, creating a sensation of virtual presence at events that occur far away. This sensation gives meaning to the notions of 'real time' and of a 'present' that is shared within and among societies”in other words, a sensation of contemporaneity. But how were time and space conceived before modernity? When did this begin to change in Europe? To help answer such questions, this volume looks at the exchange of information and the development of communications networks at the dawn of journalism, when widespread public and private networks first emerged for the transmission of political news. What happened in Prague quickly reached Venice, and what happened in Naples was soon the talk of Hamburg. Gradually, enough became known about daily affairs around Europe for people to begin to think in terms of a 'shared present'. An analysis of contemporaneity adds a new dimension to the study of the origins of news and media history, as well as to the origins of a European identity. For whilst our understanding of the circulation of manuscript newsletters and printed reports has increased in recent years, much less is known about the impact of this burgeoning journalism on a pan-European scale. Each essay in this volume explores the ways in which this international impact helped foster a developing sense of contemporaneity that encompassed not just single countries, but Europe as a whole. Taken together the collection offers the first panoramic view of the way stories were born, grew and matured during their transmission from source to source, from country to country. The results published here suggest that a continent-wide network, including manuscript and print, for the transmission of stories from place to place, existed and was effective.

This book was released on 2012-02-17 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Center for Science and Engineering Statistics (NCSES), at the U.S. National Foundation, is 1 of 14 major statistical agencies in the federal government, of which at least 5 collect relevant information on science, technology, and innovation activities in the United States and abroad. The America COMPETES Reauthorization Act of 2010 expanded and codified NCSES's role as a U.S. federal statistical agency. Important aspects of the agency's mandate include collection, acquisition, analysis, and reporting and dissemination of data on research and development trends, on U.S. competitiveness in science, technology, and research and development, and on the condition and progress of U.S. science, technology, engineering, and mathematics (STEM) education. Improving Measures of Science, Technology and Innovation: Interim Report examines the status of the NCSES's science, technology, and innovation (STI) indicators. This report assesses and provides recommendations regarding the need for revised, refocused, and newly developed indicators designed to better reflect fundamental and rapid changes that are reshaping global science, technology and innovation systems. The book also determines the international scope of STI indicators and the need for developing new indicators that measure developments in innovative activities in the United States and abroad, and Offers foresight on the types of data, metrics and indicators that will be particularly influential in evidentiary policy decision-making for years to come. In carrying out its charge, the authoring panel undertook a broad and comprehensive review of STI indicators from different countries, including Japan, China, India and several countries in Europe, Latin America and Africa. Improving Measures of Science, Technology, and Innovation makes recommendations for near-term action by NCSES along two dimensions: (1) development of new policy-relevant indicators that are based on NCSES survey data or on data collections at other statistical agencies; and (2) exploration of new data extraction and management tools for generating statistics, using automated methods of harvesting unstructured or scientometric data and data derived from administrative records.

This book was released on 2012-03-27 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increasing popularization of personal hand-held mobile devices, more people use them to establish network connectivity and to query and share data among themselves in the absence of network infrastructure, creating mobile social networks (MSNet). Since users are only intermittently connected to MSNets, user mobility should be exploited to bridge network partitions and forward data. Currently, data route/forward approaches for such intermittently connected networks are commonly "store-carry-and-forward" schemes, which exploit the physical user movements to carry data around the network and overcome path disconnection. And since the source and destination may be far away from each other, the delay for the destination to receive the data from the source may be long. MSNets can be viewed as one type of socially-aware delay tolerant networks (DTNs). Observed from social networks, the contact frequencies are probably different between two friends and two strangers, and this difference should be taken into consideration when designing data dissemination and query schemes in MSNets. In this book, the fundamental concepts of MSNets are introduced including the background, key features and potential applications of MSNets, while also presenting research topics, such as, MSNets as realistic social contact traces and user mobility models. Because the ultimate goal is to establish networks that allow mobile users to quickly and efficiently access interesting information, particular attention is paid to data dissemination and query schemes in subsequent sections. Combined with geography information, the concepts of community and centrality are employed from a social network perspective to propose several data dissemination and query schemes, and further use real social contact traces to evaluate their performance, demonstrating that such schemes achieve better performance when exploiting more social relationships between users.
