Research on international norms has yet to answer satisfactorily some of our own most important questions about the origins of norms and the conditions under which some norms win out over others. The authors argue that international relations (IR) theorists should engage more with research in moral psychology and neuroscience to advance theories of norm emergence and resonance. This Element first provides an overview of six areas of research in neuroscience and moral psychology that hold particular promise for norms theorists and international relations theory more generally. It next surveys existing literature in IR to see how literature from moral psychology is already being put to use, and then recommends a research agenda for norms researchers engaging with this literature. The authors do not believe that this exchange should be a one-way street, however, and they discuss various ways in which the IR literature on norms may be of interest and of use to moral psychologists, and of use to advocacy communities.
Natural selection causes adaptation, the fit between an organism and its environment. For example, the white and grey coloration of snowy owls living and breeding around the Arctic Circle provides camouflage from both predators and prey. In this Element, we explore a variety of such outcomes of the evolutionary process, including both adaptations and alternatives to adaptations, such as nonadaptive traits inherited from ancestors. We also explore how the concept of adaptation is used in evolutionary psychology and in animal behavior, and the adequacy of methods used to confirm evolutionary accounts of human traits and behaviors.
Reprinting, republishing and re-covering old books in new clothes is an established publishing practice. How are books that have fallen out of taste and favour resituated by publishers, and recognised by readers, as relevant and timely? This Element outlines three historical textures within British culture of the late 1970s and early 1980s – History, Remembrance and Heritage – that enabled Virago's reprint publishing to become a commercial and cultural success. With detailed archival case studies of the Virago Reprint Library, Testament of Youth and the Virago Modern Classics, it elaborates how reprints were profitable for the publisher and moved Virago's books - and the Virago brand name - from the periphery of culture to the centre. Throughout Virago's reprint publishing - and especially with the Modern Classics - the epistemic revelation that women writers were forgotten and could, therefore, be rediscovered, was repeated, again and again, and made culturally productive through the marketplace.
A posthumanist approach problematizes the separateness and centrality of humans in understanding the world around us. Posthumanism does not deny the role of humans but questions the assumption that it is human activity and agency that should be given pride of place in any analysis of social activity. This carries important and interesting implications for the study of World Englishes, some of which are explored in this Element. Sections 3 and 4, respectively, explore posthumanism in relation to two specific topics in World Englishes, creativity and language policy. These topics have been chosen because they allow us to see the contributions that posthumanism can make to a micro-level (creativity) as well as macro-level (language policy) topic.
This Cambridge Element examines the role and nature of focus on form in second language acquisition. An overall assessment of the role of instruction and the nature of language is provided. Instruction might have a facilitative role in the rate of acquisition. The Element briefly reviews empirical research examining the relative effects of different types of focus on form and presents some of the key implications for second language learning and teaching. An effective focus on form type is one that is input and meaning oriented. Manipulating input to facilitate language processing and form-meaning connections might enhance second language acquisition.
Insect-scale flapping wing flight vehicles can conduct environmental monitoring, disaster assessment, mapping, positioning and security in complex and challenging surroundings. To develop bio-inspired flight vehicles, systematic probing based on the particular category of flight vehicles is needed. This Element addresses the aerodynamics, aeroelasticity, geometry, stability and dynamics of flexible flapping wings in the insect flight regime. The authors highlight distinct features and issues, contrast aerodynamic stability between rigid and flexible wings, present the implications of the wing-aspect ratio, and use canonical models and dragonflies to elucidate scientific insight as well as technical capabilities of bio-inspired design.
This Element aims to connect the literature of street-level bureaucrats with that of policy entrepreneurship in order to analyze why and how bureaucrats operating at the street level can promote policy change in public administration at the individual level. I demonstrate how street-level bureaucrats act as policy entrepreneurs in different contexts around the globe to promote policy change and analyze what they think of policy entrepreneurship and what they do about it in practice. For this purpose, I use multiple research methods: a survey, in-depth interviews, focus groups and textual analyses. I also offer recommendations to decision-makers to promote street-level policy entrepreneurship, highlighting the benefits of doing so. Lastly, I critically discuss the normative aspects of street-level policy entrepreneurship: ultimately, is it desirable?
What are the meanings of number expressions, and what can they tell us about questions of central importance to the philosophy of mathematics, specifically 'Do numbers exist?' This Element attempts to shed light on this question by outlining a recent debate between substantivalists and adjectivalists regarding the semantic function of number words in numerical statements. After highlighting their motivations and challenges, I develop a comprehensive polymorphic semantics for number expressions. I argue that accounting for the numerous meanings and how they are related leads to a strengthened argument for realism, one which renders familiar forms of nominalism highly implausible.
Recent advances in statistical approaches called phylogenetic comparative methods (PCMs) have provided paleontologists with a powerful set of analytical tools for investigating evolutionary tempo and mode in fossil lineages. However, attempts to integrate PCMs with fossil data often present workers with practical challenges or unfamiliar literature. This Element presents guides to the theory behind and the application of PCMs with fossil taxa. Based on an empirical dataset of Paleozoic crinoids, example analyses are presented to illustrate common applications of PCMs to fossil data, including investigating patterns of correlated trait evolution and macroevolutionary models of morphological change. The authors emphasize the importance of accounting for sources of uncertainty and discuss how to evaluate model fit and adequacy. Finally, the authors discuss several promising methods for modeling heterogeneous evolutionary dynamics with fossil phylogenies. Integrating phylogeny-based approaches with the fossil record provides a rigorous, quantitative perspective on understanding key patterns in the history of life.
How Christian people have framed the meaning of violence within their faith tradition has been a complex process subject to all manner of historical, cultural, political, ethnic and theological contingencies. As a tradition encompassing widely divergent beliefs and perspectives, Christianity has, over two millennia, adapted to changing cultural and historical circumstances. To grasp the complexity of this tradition and its involvement with violence requires attention to specific elements explored in this Element: the scriptural and institutional sources for violence; the faith commitments and practices that join communities and sanction both resistance to and authorization for violence; and select historical developments that altered the power wielded by Christianity in society, culture and politics. Relevant issues in social psychology and the moral action guides addressing violence affirmed in Christian communities provide a deeper explanation for the motivations that have led to the diverse interpretations of violence avowed in the Christian tradition.
This short history of Shakespeare in global performance-from the re-opening of London theatres upon the restoration of the monarchy in 1660 to our present multicultural day-provides a comprehensive overview of Shakespeare's theatrical afterlife and introduces categories of analysis and understanding to make that afterlife intellectually meaningful. Written for both the advanced student and the practicing scholar, this work enables readers to situate themselves historically in the broad field of Shakespeare performance studies and equips them with analytical tools and conceptual frameworks for making their own contributions to the field.
In the first decade of life, children become bilingual in different language learning environments. Many children start learning two languages from birth (Bilingual First Language Acquisition). In early childhood hitherto monolingual children start hearing a second language through daycare or preschool (Early Second Language Acquisition). Yet other hitherto monolingual children in middle childhood may acquire a second language only after entering school (Second Language Acquisition). This Element explains how these different language learning settings dynamically affect bilingual children's language learning trajectories. All children eventually learn to speak the societal language, but they often do not learn to fluently speak their non-societal language and may even stop speaking it. Children's and families' harmonious bilingualism is threatened if bilingual children do not develop high proficiency in both languages. Educational institutions and parental conversational practices play a pivotal role in supporting harmonious bilingual development.
Derek Parfit (1942–2017) was one of the most important and influential moral philosophers of the late 20th and early 21st centuries. This Element offers a critical introduction to his wide-ranging ethical thought, focusing especially on his two most significant works, Reasons and Persons (1984) and On What Matters (2011), and their contribution to the consequentialist moral tradition. Topics covered include: rationality and objectivity, distributive justice, self-defeating moral theories, Parfit's Triple Theory (according to which consequentialism, contractualism, and Kantian ethics ultimately converge), personal identity, and population ethics.
