The Pacific is historically an area of enormous linguistic diversity, where talk figures as a central component of social life. Pacific communities also represent diverse contact zones, where between indigenous and introduced institutions and ideas; between local actors and outsiders; and involving different lingua franca, colonial, and local language varieties. Contact between colonial and post-colonial governments, religious institutions, and indigenous communities has spurred profound social change, irrevocably transforming linguistic ideologies and practices. Drawing on ethnographic and linguistic analyses, this edited volume examines situations of intertwined linguistic and cultural change unfolding in specific Pacific locations in the late twentieth and early twenty-first centuries. Its overarching concern is with the multiple ways that processes of historical change have shaped and been shaped by linguistic ideologies reflexive sensibilities about languages and language useheld by Pacific peoples and other agents of change. The essays demonstrate that language and linguistic practices are linked to changing consciousness of self and community through notions of agency, morality, affect, authority, and authenticity. In times of cultural contact, communities often experience language change at an accelerated rate. This is particularly so in small-scale communities where innovations and continuity routinely depend on the imagination, creativity, and charisma of fewer individuals. The essays in this volume provide evidence of this potential and a record of their voices, as they document new types of local actors, e.g., pastors, Bible translators, teachers, political activists, spirit mediums, and tour guides, some of whom introduce, innovate, legitimate, or resist new ideas and ways to express them through language. Drawing on and transforming metalinguistic concepts, local actors (re)shape language, reproducing and changing the communicative economy. In the process, they cultivate new cultural conceptions of language, for example, as a medium for communicating religious knowledge and political authority, and for constructing social boundaries and transforming relationships of domination.

The essays in this volume demonstrate that language and linguistic practices are linked to changing changing consciousness of self and community through notions of agency, morality, affect, authority, and authenticity.

How data science and the analysis of networks help us solve the puzzle of unintended consequences. Social life is full of paradoxes. Our intentional actions often trigger outcomes that we did not intend or even envision. How do we explain those unintended effects and what can we do to regulate them? In Decoding the Social World, Sandra González-Bailón explains how data science and digital traces help us solve the puzzle of unintended consequences—offering the solution to a social paradox that has intrigued thinkers for centuries. Communication has always been the force that makes a collection of people more than the sum of individuals, but only now can we explain why: digital technologies have made it possible to parse the information we generate by being social in new, imaginative ways. And yet we must look at that data, González-Bailón argues, through the lens of theories that capture the nature of social life. The technologies we use, in the end, are also a manifestation of the social world we inhabit. González-Bailón discusses how the unpredictability of social life relates to communication networks, social influence, and the unintended effects that derive from individual decisions. She describes how communication generates social dynamics in aggregate (leading to episodes of “collective effervescence”) and discusses the mechanisms that underlie large-scale diffusion, when information and behavior spread “like wildfire.” She applies the theory of networks to illuminate why collective outcomes can differ drastically even when they arise from the same individual actions. By opening the black box of unintended effects, González-Bailón identifies strategies for social intervention and discusses the policy implications—and how data science and evidence-based research embolden critical thinking in a world that is constantly changing.

This book summarizes current understanding of the scientific, clinical, and technical issues surrounding the use of contact lenses. It discusses the special occupational conditions experienced by military personnel, particularly in extreme environments, that give rise to the question of whether or not to use contact lenses. Experts in optometry, ophthalmology, visual psychophysics, and engineering describe recent developments in design and use; and representatives of the military services provide examples of actual situations in aerospace settings. Considerations in Contact Lens Use Under Adverse Conditions will be of particular interest to those involved in the design of contact lenses and those responsible for occupational safety and health matters in the private sector.

In the past decade, few subjects at the intersection of medicine and sports have generated as much public interest as sports-related concussions - especially among youth. Despite growing awareness of sports-related concussions and campaigns to educate athletes, coaches, physicians, and parents of young athletes about concussion recognition and management, confusion and controversy persist in many areas. Currently, diagnosis is based primarily on the symptoms reported by the individual rather than on objective diagnostic markers, and there is little empirical evidence for the optimal degree and duration of physical rest needed to promote recovery or the best timing and approach for returning to full physical activity. Sports-Related Concussions in Youth: Improving the Science, Changing the Culture reviews the science of sports-related concussions in youth from elementary school through young adulthood, as well as in military personnel and their dependents. This report recommends actions that can be taken by a range of audiences - including research funding agencies, legislatures, state and school superintendents and athletic directors, military organizations, and equipment manufacturers, as well as youth who participate in sports and their parents - to improve what is known about concussions and to reduce their occurrence. Sports-Related Concussions in Youth finds that while some studies provide useful information, much remains unknown about the extent of concussions in youth; how to diagnose, manage, and prevent concussions; and the short- and long-term consequences of concussions as well as repetitive head impacts that do not result in concussion symptoms. The culture of sports negatively influences athletes' self-reporting of concussion symptoms and their adherence to return-to-play guidance. Athletes, their teammates, and, in some cases, coaches and parents may not fully appreciate the health threats posed by concussions. Similarly, military recruits are immersed in a culture that includes devotion to duty and service before self, and the critical nature of concussions may often go unheeded. According to Sports-Related Concussions in Youth, if the youth sports community can adopt the belief that concussions are serious injuries and emphasize care for players with concussions until they are fully recovered, then the culture in which these athletes perform and compete will become much safer. Improving understanding of the extent, causes, effects, and prevention of sports-related concussions is vitally important for the health and well-being of youth athletes. The findings and recommendations in this report set a direction for research to reach this goal.

This book describes a wide variety of speculations by many authors about the consequences for humanity of coming into contact with extraterrestrial intelligence. The assumptions underlying those speculations are examined, and some conclusions are drawn. The book emphasizes the consequences of contact rather than the search, and takes account of popular views. As necessary background, the book also includes brief summaries of the history of thinking about extraterrestrial intelligence, searches for life and for signals, contrasting paradigms of how contact might take place, and the paradox that those paradigms allegedly create.

In April 2010, fifty years to the month after the first experiment in the Search for Extraterrestrial Intelligence (SETI), scholars from a range of disciplines—including astronomy, mathematics, anthropology, history, and cognitive science—gathered at NASA's biennial Astrobiology Science Conference (AbSciCon) for a series of sessions on the search for intelligent life. This book highlights the most recent developments in SETI discussed at that conference, emphasizing the ways that SETI has grown since its inception. The volume covers three broad themes: First, leading researchers examine the latest developments in observational SETI programs, as well as innovative proposals for new search strategies and novel approaches to signal processing. Second, both proponents and opponents of "Active SETI" debate whether humankind should be transmitting intentional signals to other possible civilizations, rather than only listening. Third, constructive proposals for interstellar messages are juxtaposed with critiques that ask whether any meaningful exchange is possible with an independently evolved civilization, given the constraints of contact at interstellar distances, where a round-trip exchange could take centuries or millennia. As we reflect on a half-century of SETI research, we are reminded of the expansion of search programs made possible by technological and conceptual advances. In this spirit of ongoing exploration, the contributors to this book advocate a diverse range of approaches to make SETI increasingly more powerful and effective, as we embark on the next half-century of searching for intelligence beyond Earth.

In this fascinating collection of essays, an international group of scholars explores the sonic consequences of transcultural contact in the early modern period. They examine how cultural configurations of sound impacted communication, comprehension, and the categorisation of people. Addressing questions of identity, difference, sound, and subjectivity in global early modernity, these authors share the conviction that the body itself is the most intimate of contact zones, and that the culturally contingent systems by which sounds made sense could be foreign to early modern listeners and to present day scholars. Drawing on a global range of archival evidence—from New France and New Spain, to the slave ships of the Middle Passage, to China, Europe, and the Mediterranean court environment—this collection challenges the privileged position of European acoustical practices within the discipline of global-historical musicology. The discussion of Black and non-European experiences demonstrates how the production of ‘the canon’ in the cosmopolitan centres of colonial empires was underpinned by processes of human exploitation and extraction of resources. As such, this text is a timely response to calls within the discipline to decolonise music history and to contextualise the canonical works of the European past. This volume is accessible to a wide and interdisciplinary audience, not only within musicology, but also to those interested in early modern global history, sound studies, race, and slavery.

Jannis Kallinikos analyzes the recent spectacular growth of information and the self-propelling processes through which technological information is increasingly generated out of the reshuffling and recombination of available and interoperable information sources. He argues that information is no longer simply a resource but a pervading element of socio-economic life that is crucially involved in the redefinition of a variety of organizational practices and modes of economic action. Academics and students in a variety of disciplines, including information studies, information systems, manageme.
