Surveys the online social habits of American teens and analyzes the role technology and social media plays in their lives, examining common misconceptions about such topics as identity, privacy, danger, and bullying.

Mark Wilson presents a highly original and broad-ranging investigation of the way we get to grips with the world conceptually, and the way that philosophical problems commonly arise from this. Words such as colour, shape, solidity exemplify the commonplace conceptual tools we employ to describe and order the world around us. But the world's goods are complex in their behaviors and we often overlook the subtle adjustments that our evaluative terms undergo as their usage becomes gradually adapted to different forms of supportive circumstance. Wilson not only explains how these surprising strategies of hidden management operate, but also tells the astonishing story of how faulty schemes and great metaphysical systems sometimes spring from a simple failure to recognize the innocent wanderings to which our descriptive words are heir. Wilson combines traditional philosophical concerns about human conceptual thinking with illuminating data derived from a large variety of fields including physics and applied mathematics, cognitive psychology, and linguistics. Wandering Significance offers abundant new insights and perspectives for philosophers of language, mind, and science, and will also reward the interest of psychologists, linguists, and anyone curious about the mysterious ways in which useful language obtains its practical applicability.

Focusing on a period neglected by scholars, Higgins reconstructs how during the colonial period criollos - individuals identified as being of Spanish descent born in America - elaborated a body of knowledge, an "archive," in order to establish their intellectual autonomy within the Spanish colonial administrative structures." "This book opens up an important area of research that will be of interest to scholars and students of Spanish American colonial literature and history."--BOOK JACKET.

Globalizing Race explores how intersections between French antisemitism and imperialism shaped the development of European racial thought. Ranging from the African misadventures of the antisemitic Marquis de Morès to the Parisian novels and newspapers of late nineteenth-century professional antisemites, Dorian Bell argues that France’s colonial expansion helped antisemitism take its modern, racializing form—and that, conversely, antisemitism influenced the elaboration of the imperial project itself. Globalizing Race radiates from France to place authors like Guy de Maupassant and Émile Zola into sustained relation with thinkers from across the ideological spectrum, including Hannah Arendt, Friedrich Nietzsche, Frantz Fanon, Karl Marx, Max Horkheimer, and Theodor Adorno. Engaging with what has been called the “spatial turn” in social theory, the book offers new tools for thinking about how racisms interact across space and time. Among these is what Bell calls racial scalarity. Race, Bell argues, did not just become globalized when European racism and antisemitism accompanied imperial penetration into the farthest reaches of the world. Rather, race became most thoroughly global as a method for constructing and negotiating the different scales (national, global, etc.) necessary for the development of imperial capitalism. As France, Europe, and the world confront a rising tide of Islamophobia, Globalizing Race also brings into fascinating focus how present-day French responses to Muslim antisemitism hark back to older, problematic modes of representing the European colonial periphery.

Plants produce a huge array of natural products (secondary metabolites). These compounds have important ecological functions, providing protection against attack by herbivores and microbes and serving as attractants for pollinators and seed-dispersing agents. They may also contribute to competition and invasiveness by suppressing the growth of neighboring plant species (a phenomenon known as allelopathy). Humans exploit natural products as sources of drugs, flavoring agents, fragrances and for a wide range of other applications. Rapid progress has been made in recent years in understanding natural product synthesis, regulation and function and the evolution of metabolic diversity. It is timely to bring this information together with contemporary advances in chemistry, plant biology, ecology, agronomy and human health to provide a comprehensive guide to plant-derived natural products. Plant-derived natural products: synthesis, function and application provides an informative and accessible overview of the different facets of the field, ranging from an introduction to the different classes of natural products through developments in natural product chemistry and biology to ecological interactions and the significance of plant-derived natural products for humans. In the final section of the book a series of chapters on new trends covers metabolic engineering, genome-wide approaches, the metabolic consequences of genetic modification, developments in traditional medicines and nutraceuticals, natural products as leads for drug discovery and novel non-food crops.

From the preface: "The 1966 'Human Factors' edition focused on the contemporary threat of Maoist insurgencies, particularly in Southeast Asia, and also drew extensively on World War II resistance movements in Europe. Much of this information is still relevant and has been retained and integrated. In the post-Cold War world, the most important insurgencies tend to be ethnic and religious. Long-simmering conflicts, sometimes with roots in colonial policies, have become prominent; examples include the Liberation Tigers of Tamil Eelam (LTTE) in Sri Lanka, Euskadi Ta Askatasuna (Basque Homeland and Freedom or ETA) in Spain, the Hutu-Tutsi genocides, the Ushtia �lirimtare e Kosov�s (Kosovo Liberation Army, or KLA), and the Provisional Irish Republican Army (PIRA). Battle lines in these conflicts are often drawn along ethnic lines, even when land or politics are the immediate issues in contention. The other important new category is extremist religious movements, most prominently Islamic groups, including regional insurgent movements like Hizbollah and Harakat al-Muqawamah al'Isla�miyyah (Islamic Resistance Movement, or HAMAS) and global movements like Al Qaeda. These present a different profile of ideology, organizational forms, and psychology than either Cold War Maoists or post-colonial ethnic insurgencies (although the Palestinian cause could be considered a post-colonial issue). Globalization has also changed underground operations in numerous ways. Insurgencies, enabled by low-cost transportation, Internet based communications, and other information technologies, can more easily recruit, communicate, and operate across borders. It is correspondingly much more difficult to contain an insurgency in a region. Global media has led to development of new tactics, in particular new types of terrorism, designed to capture worldwide attention. Compared with what was available in the 1960s, there are orders of magnitude more academic research available relevant to this study's topics. We were able to draw on more recent work in psychology, political science, economics, sociology, organizational studies, and communications studies. Readers of this edition will, over the course of eleven chapters, get a wide exposure to basic concepts from a number of disciplines".
