Digital technologies have changed the public arena, but there is little scholarly consensus about how they have done so. This Element lays out a new framework for the digitally mediated public arena by identifying structural changes and continuities with the pre-digital era. It examines three country cases – the United States, Germany, and China. In these countries and elsewhere, the emergence of new infrastructures such as search engines and social media platforms increasingly mediate and govern the visibility and reach of information, and thus reconfigure the transmission belt between citizens and political elites. This shift requires a rethinking of the workings and dysfunctions of the contemporary public arena and ways to improve it.
This Element examines urban imaginaries during the expansion of international news between the late nineteenth and the early twentieth centuries, when everyday information about faraway places found its way into newspapers all over the world. Building on the premise that news carried an unprecedented power to shape representations of the world, it follows this development as it made its way to regular readers beyond the dominant information poles, in the great port-cities of the South American Atlantic. Based on five case studies of typical turn-of-the-century foreign news, Lila Caimari shows how current events opened windows onto distant cities, feeding a new world horizon that was at once wider and eminently urban.
Building effective state institutions before introducing democracy is widely presumed to improve different development outcomes. Conversely, proponents of this “stateness-first” argument anticipate that democratization before state building yields poor development outcomes. In this Element, we discuss several strong assumptions that (different versions of) this argument rests upon and critically evaluate the existing evidence base. In extension, we specify various observable implications. We then subject the stateness-first argument to multiple tests, focusing on economic growth as an outcome. First, we conduct historical case studies of two countries with different institutional sequencing histories, Denmark and Greece, and assess the stateness-first argument (e.g., by using a synthetic control approach). Thereafter, we draw on an extensive global sample of about 180 countries, measured across 1789–2019 and leverage panel regressions, preparametric matching, and sequence analysis to test a number of observable implications. Overall, we find little evidence to support the stateness-first argument.
The first section of this Element reviews the history of LGBTQ rights in the region since the 1960s. The second section reviews explanations for the expansion of rights and setbacks, especially since the mid 2000s. Explanations are organized according to three themes: (1) the (re-)emergence of a religious cleavage; (2) the role of political institutions such as presidential leadership, political parties, federalism, courts, and transnational forces; and (3) the role of social movement strategies, and especially, unity. The last section compares the progress on LGBTQ rights (significant) with reproductive rights (insignificant). This Element concludes with an overview of the causes and possible future direction of the current backlash against LGBTQ rights.
Movements and parties have given rise to two largely separates specialties in the social sciences. This Element is an effort to link the two literatures, using evidence from American political development. It identifies five relational mechanisms governing movement/party relations: two of them short term, two intermediate term, and one long-term. It closes with a reflection on the role of movement/party relations in democratization and for democratic resilience.
Metamaterials, including their two-dimensional counterparts, are composed of subwavelength-scale artificial particles. These materials have novel electromagnetic properties, and can be artificially tailored for various applications. Based on metamaterials and metasurfaces, many abnormal physical phenomena have been realized, such as negative refraction, invisible cloaking, abnormal reflection and focusing, and many new functions and devices have been developed. The effective medium theory lays the foundation for design and application of metamaterials and metasurfaces, connecting metamaterials with real world applications. In this Element, the authors combine these essential ingredients, and aim to make this Element an access point to this field. To this end, they review classical theories for dielectric functions, effective medium theory, and effective parameter extraction of metamaterials, also introducing front edge technologies like metasurfaces with theories, methods, and potential applications. Energy densities are also included.
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.
