An Element on the role of violence in the traditional religions of the Pacific Ilands (Melanesia, Micronesia and Polynesia) and on violent activity in islander religious life after the opening of Oceania to the modern world. This work covers such issues as tribal warfare, sorcery and witchcraft, traditional punishment and gender imbalance. and moves on to consider reprisals against foreign intruders in the Pacific and the continuation of old types of violence in spite of massive socio-religious change.
Complex networks are typically not homogeneous, as they tend to display an array of structures at different scales. A feature that has attracted a lot of research is their modular organisation, i.e., networks may often be considered as being composed of certain building blocks, or modules. In this Element, the authors discuss a number of ways in which this idea of modularity can be conceptualised, focusing specifically on the interplay between modular network structure and dynamics taking place on a network. They discuss, in particular, how modular structure and symmetries may impact on network dynamics and, vice versa, how observations of such dynamics may be used to infer the modular structure. They also revisit several other notions of modularity that have been proposed for complex networks and show how these can be related to and interpreted from the point of view of dynamical processes on networks.
Teaching Shakespeare through performance has a long history, and active methods of teaching and learning are a logical complement to the teaching of performance. Virtual reality ought to be the logical extension of such active learning, providing an unrivalled immersive experience of performance that overcomes historical and geographical boundaries. But what are the key advantages and disadvantages of virtual reality, especially as it pertains to Shakespeare? And more interestingly, what can Shakespeare do for VR (rather than vice versa)? This Element, the first on its topic, explores the ways that virtual reality can be used in the classroom and the ways that it might radically change how students experience and think about Shakespeare in performance.
This Element introduces the exotic wave phenomena arising from the extremely small optical refractive index, and sheds light on the underlying mechanisms, with a primary focus on the basic concepts and fundamental wave physics. The authors reveal the exciting applications of ENZ metamaterials, which have profound impacts over a wide range of fields of science and technology. The sections are organized as follows: in Section 2, the authors demonstrate the extraordinary wave properties in ENZ metamaterials, analyzing the unique wave dynamics and the resulting effects. Section 3 is dedicated to introducing various realization methods of the ENZ metamaterials with periodic and non-periodic styles. The applications of ENZ metamaterials are discussed in Sections 4 and 5, from the perspectives of microwave engineering, optics, and quantum physics. The authors close in Section 6 by presenting an outlook on the development of ENZ metamaterials and discussing the key challenges addressed in future works.
In many systems consisting of interacting subsystems, the complex interactions between elements can be represented using multilayer networks. However percolation, key to understanding connectivity and robustness, is not trivially generalised to multiple layers. This Element describes a generalisation of percolation to multilayer networks: weak multiplex percolation. A node belongs to a connected component if at least one of its neighbours in each layer is in this component. The authors fully describe the critical phenomena of this process. In two layers with finite second moments of the degree distributions the authors observe an unusual continuous transition with quadratic growth above the threshold. When the second moments diverge, the singularity is determined by the asymptotics of the degree distributions, creating a rich set of critical behaviours. In three or more layers the authors find a discontinuous hybrid transition which persists even in highly heterogeneous degree distributions, becoming continuous only when the powerlaw exponent reaches $1+1/(M-1)$ for $M$ layers.
Stretchable electronics is one of the transformative pillars of future flexible electronics. As a result, the research on new passive and active materials, novel designs, and engineering approaches has attracted significant interest. Recent studies have highlighted the importance of new approaches that enable the integration of high-performance materials, including, organic and inorganic compounds, carbon-based and layered materials, and composites to serve as conductors, semiconductors or insulators, with the ability to accommodate electronics on stretchable substrates. This Element presents a discussion about the strategies that have been developed for obtaining stretchable systems, with a focus on various stretchable geometries to achieve strain invariant electrical response, and summarises the recent advances in terms of material research, various integration techniques of high-performance electronics. In addition, some of the applications, challenges and opportunities associated with the development of stretchable electronics are discussed.
This Element explores the papacy's engagement in authorial publishing in late antiquity and the Middle Ages. The opening discussion demonstrates that throughout the medieval period, papal involvement in the publication of new works was a phenomenon, which surged in the eleventh century. The efforts by four authors to use their papal connexions in the interests of publicity are examined as case studies. The first two are St Jerome and Arator, late antique writers who became highly influential partly due to their declaration that their literary projects enjoyed papal sanction. Appreciation of their publication strategies sets the scene for a comparison with two eleventh-century authors, Fulcoius of Beauvais and St Anselm. This Element argues that papal involvement in publication constituted a powerful promotional technique. It is a hermeneutic that brings insights into both the aspirations and concerns of medieval authors. This title is also available as Open Access on Cambridge Core.
Ancient iron formations - iron and silica-rich chemical sedimentary rocks that formed throughout the Precambrian eons - provide a significant part of the evidence for the modern scientific understanding of palaeoenvironmental conditions in Archaean (4.0–2.5 billion years ago) and Proterozoic (2.5–0.539 billion years ago) times. Despite controversies regarding their formation mechanisms, iron formations are a testament to the influence of the Precambrian biosphere on early ocean chemistry. As many iron formations are pure chemical sediments that reflect the composition of the waters from which they precipitated, they can also serve as nuanced geochemical archives for the study of ancient marine temperatures, redox states, and elemental cycling, if proper care is taken to understand their sedimentological context.
This Element offers a first-person phenomenological history of watching productions of Shakespeare during the pandemic year of 2020. The first section of the Element explores how Shakespeare 'went viral' during the first lockdown of 2020 and considers how the archival recordings of Shakespeare productions made freely available by theatres across Europe and North America impacted on modes of spectatorship and viewing practices, with a particular focus on the effect of binge-watching Hamlet in lockdown. The Element's second section documents two made-for-digital productions of Shakespeare by Oxford-based Creation Theatre and Northern Irish Big Telly, two companies who became leaders in digital theatre during the pandemic. It investigates how their productions of The Tempest and Macbeth modelled new platform-specific ways of engaging with audiences and creating communities of viewing at a time when, in the UK, government policies were excluding most non-building-based theatre companies and freelancers from pandemic relief packages.
Learning through the medium of a second or additional language is becoming very common in different parts of the world because of the increasing use of English as the language of instruction and the mobility of populations. This situation demands a specific approach that considers multilingualism as its core. Pedagogical translanguaging is a theoretical and instructional approach that aims at improving language and content competences in school contexts by using resources from the learner's whole linguistic repertoire. Pedagogical translanguaging is learner-centred and endorses the support and development of all the languages used by learners. It fosters the development of metalinguistic awareness by softening of boundaries between languages when learning languages and content. This Element looks at the way pedagogical translanguaging can be applied in language and content classes and how it can be valuable for the protection and promotion of minority languages.

The United States defence economy is remarkable for a number of reasons - including sheer size. It receives a significant (albeit decreasing) share of GDP and has a significant international footprint. Its purpose is to provide the resources for national defence - against a set of complex and capable adversaries. The main players in the defence economy are households, and the Federal Government. The associated interactions determine the resources provided for national defence and their allocation among various defence needs. This Element focuses primarily on interactions between government and industrial suppliers within the institutional peculiarities of the defence marketplace. This includes the developments that have determined the course of defence industry consolidation post-Cold War. The authors also highlight the persistent gap between resources available for defence and the means to execute the National Security Strategy. Finally, they offer some tentative thoughts regarding developments likely to shape the defence economy's future.
Religion and spirituality have been scarcely addressed in heritage preservation history, discourse, and practice. More recently, increased interest in the intersections between the study of religion and heritage preservation in both academic studies and institutional initiatives highlight obstacles that the field has yet to overcome theoretically and methodologically. This Element surveys the convergences of religious and heritage traditions. It argues that the critical heritage turn has not adequately considered the legacy of secularism that underpins the history and contemporary practices of heritage preservation. This omission is what has left the field of heritage studies ill-equipped to support the study and management of a heritage of religion broadly construed.
Philosophical thinking about time is characterised by tensions between competing conceptions. Different sources of evidence yield different conclusions about it. Common sense suggests there is an objective present, and that time is dynamic. Science recognises neither feature. This Element examines McTaggart's argument for the unreality of time, which epitomises this tension, showing how it gave rise to the A-theory/B-theory debate. Each theory is in tension with either ordinary or scientific thinking, so must accommodate the competing conception. Reconciling the A-theory with science does not look promising. Prospects look better for the B-theory's attempt to accommodate ordinary thinking about time.
The Process of Wellbeing develops an anthropological perspective on wellbeing as an intersubjective process that can be approached through the prism of three complementary conceptual framings: conviviality; care; and creativity. Drawing on ethnographic discussions of these themes in a range of cultural contexts around the world, it shows how anthropological research can help to enlarge and refine understandings of wellbeing, through dialogue with different perspectives and understandings of what it means to live well with others and the skills required to do so. Rather than a state or achievement, wellbeing comes into view here as an ongoing process that involves human and nonhuman others. It does not pertain to the individual alone, but plays out within the relations of care that constitute people, moving and thriving in circulation through affective environments.
Real networks comprise from hundreds to millions of interacting elements and permeate all contexts, from technology to biology to society. All of them display non-trivial connectivity patterns, including the small-world phenomenon, making nodes to be separated by a small number of intermediate links. As a consequence, networks present an apparent lack of metric structure and are difficult to map. Yet, many networks have a hidden geometry that enables meaningful maps in the two-dimensional hyperbolic plane. The discovery of such hidden geometry and the understanding of its role have become fundamental questions in network science giving rise to the field of network geometry. This Element reviews fundamental models and methods for the geometric description of real networks with a focus on applications of real network maps, including decentralized routing protocols, geometric community detection, and the self-similar multiscale unfolding of networks by geometric renormalization.
Video games can have many effects on players, some of which could be intentional effects (e.g., games designed to train health compliance behaviors), and most of which are unintentional (e.g., violent games, stereotypes, gaming disorder). Some of these areas of research have been seen as controversial, but many of the controversies can be at least partially resolved by considering the learning mechanisms underlying the effects. We describe the General Learning Model in greater detail than has been provided elsewhere, including short-term and long-term mechanisms, processes of learning and forgetting, and moderators of learning. Video games use many of the best practices to train for both mastery and for transfer of learning. The implications for re-interpreting the literature on violent video games and gaming disorder, as well as for applied social psychology broadly defined, are discussed.
Pamela Sue Anderson's A Feminist Philosophy of Religion (1998) and Grace Jantzen's Becoming Divine: Towards a Feminist Philosophy of Religion (1998) set the tone for subsequent feminist philosophies of religion. This Element builds upon the legacy of their investigations, revisiting and extending aspects of their work for a contemporary context struggling with the impact of 'post-truth' forms of politics. Reclaiming the power of collective action felt in religious community and the importance of the struggle for truth enables a changed perspective on the world, itself necessary to realise the feminist desire for more flourishing forms of life and relationship crucial to feminist philosophy of religion.
Even the simplest social interactions require us to gather, integrate, and act upon, multiple streams of information about others and our surroundings. In this Element, we discuss how perceptual processes provide us with an accurate account of action-relevant information in social contexts. We overview contemporary theories and research that explores how: (1) individuals perceive others' mental states and actions, (2) individuals perceive affordances for themselves, others, and the dyad, and (3) how social contexts guide our attention to modulate what we perceive. Finally, we review work on the cognitive mechanisms that make joint action possible and discuss their links to perception.
Over a span of 1000 years beginning around 800CE, the people of the Pacific Islands undertook a remarkable period of voyaging, political evolution, and cross-cultural interactions. Polynesian navigators encountered previously uninhabited lands, as well as already inhabited islands and the coast of the Americas. Island societies saw epic sagas of political competition and intrigue, documented through oral traditions and the monuments and artefacts recovered through archaeology. European entry into the region added a new episode of interaction with strange people from over the horizon. These histories provide an important cross-cultural perspective for the concept of 'the Middle Ages' from outside of the usual Old World focus.
The empirical literature on the contributions of human capital investments to economic growth shows mixed results. While evidence from OECD countries demonstrates that human capital accumulation is associated with growth accelerations, the substantial efforts of developing countries to improve access to and quality of education, as a means for skill accumulation, did not translate into higher income per capita. In this Element, we propose a framework, building on the principles of 'growth diagnostics', to enable practitioners to determine whether human capital investments are a priority for a country's growth strategy. We then discuss and exemplify different tests to diagnose human capital in a place, drawing on the Harvard Growth Lab's experience in different development context, and discuss various policy options to address skill shortages.
