The characteristic – Planck – energy scale of quantum gravity makes experimental access to the relevant physics apparently impossible. Nevertheless, low energy experiments linking gravity and the quantum have been undertaken: the Page and Geilker quantum Cavendish experiment, and the Colella-Overhauser-Werner neutron interferometry experiment, for instance. However, neither probes states in which gravity remains in a coherent quantum superposition, unlike – it is claimed – recent proposals. In essence, if two initially unentangled subsystems interacting solely via gravity become entangled, then theorems of quantum mechanics show that gravity cannot be a classical subsystem. There are formidable challenges to such an experiment, but remarkably, tabletop technology into the gravity of very small bodies has advanced to the point that such an experiment might be feasible in the near future. This Element explains the proposal and what it aims to show, highlighting the important ways in which its interpretation is theory-laden.
In 2020, as Latin American countries shuttered their economies, it became clear that effective lockdowns would require states to provide income support. In a region that has historically struggled to build systems of social protection, the effort to expand benefits was notable. Policies varied in scope and generosity, but in what seemed to signify a new era of state-building, Latin American democracies demonstrated a nearly uniform commitment to providing assistance to the poor. Why did some countries implement broader and more adequate programs than others and why did countries vary in their ability to sustain support over time? This Element argues that three factors explain cross-national and cross-temporal differences in policy effort: policy legacies, unified/divided government, and fiscal space. The study shows that in settings of crisis, the democratic politics of social policy expansion shift, with traditional factors like ideology and electoral competition playing a less central role.
This Element synthesizes the current state of research on organizational social networks from its early foundations to contemporary debates. It highlights the characteristics that make the social network perspective distinctive in the organizational research landscape, including its emphasis on structure and outcomes. It covers the main theoretical developments and summarizes the research design questions that organizational researchers face when collecting and analyzing network data. Then, it discusses current debates ranging from agency and structure to network volatility and personality. Finally, the Element envisages future research directions on the role of brokerage for individuals and communities, network cognition, and the importance of past ties. Overall, the Element provides an innovative angle for understanding organizational social networks, engaging in empirical network research, and nurturing further theoretical development on the role of social interactions and connectedness in modern organizations.
This Element presents the philosophy of special relativity, from the foundations of the theory in Newtonian mechanics, through its birth out of the ashes of nineteenth-century ether theory, through the various conceptual paradoxes which the theory presents, and finally arriving at some of its connections with Einstein's later theory of general relativity. It illustrates concepts such as inertial frames, force-free motion, dynamical versus geometrical understandings of physics, the standard hierarchy of classical spacetimes, and symmetries of a physical theory; it also discusses specific topics in the foundations of special relativity such as Einstein's 1905 derivation of the Lorentz transformations, the conventionality of simultaneity, the status of frame-dependent effects, and the twin paradox.
This Element concerns itself with a particular aspect of the problem posed to monotheistic religious thought by suffering, namely the suffering of non-human creatures in nature. It makes some comparisons between Judaism, Christianity, and Islam, and then explores the problem in depth within Christian thought. After clarification of the nature of the problem, the Element considers a range of possible responses, including those based on a fall-event, those based on freedom of process, and those hypothesising a constraint on the possibilities for God as creator. Proposals based on the motif of self-emptying are evaluated. Two other aspects of the question concern God's providential relationship to the evolving creation, and the possibility of resurrection lives for animals. After consideration of the possibility of combining different explanations, the Element ends its discussion by looking at two innovative proposals at the cutting-edge of the debate.
This Element offers the first detailed study of Catharine Trotter Cockburn's philosophy and covers her contributions to philosophical debates in epistemology, metaphysics, moral philosophy, and philosophy of religion. It not only examines Cockburn's view that sensation and reflection are the sources of knowledge, but also how she draws attention to the limitations of human understanding and how she approaches metaphysical debates through this lens. In the area of moral philosophy, this Element argues that it is helpful to take seriously Cockburn's distinction between questions concerning the metaphysical foundation of morality and questions concerning the practice of morality. Moreover, this Element examines Cockburn's religious views and considers her understanding of the relation between morality and religion and her religious views concerning the resurrection and the afterlife.
International skilled heath worker migration is a key feature of the global economy, a major contributor to socio-economic development and reflective of the transnationalization of health and elder care that is underway in most OECD nations. The distribution of care and health workforce planning has previously been analysed solely within national contexts, but increasingly scholars have shown how care deficits are being addressed through transnational responses. This Element examines the complex processes that feed health worker migrants into global circulation, the losses and gains associated with such mobility and examples of good practices, where migrants, sending and destination communities experience the best possible outcomes. It will approach this issue through the lens of problems, and solutions, making connections across the micro, meso and macro within and across the sections.
This Element demonstrates how and why the alignment method can advance measurement fairness in developmental science. It explains its application to multi-category items in an accessible way, offering sample code and demonstrating an R package that facilitates interpretation of such items' multiple thresholds. It features the implications for group mean differences when differences in the thresholds between categories are ignored because items are treated as continuous, using an example of intersectional groups defined by assigned sex and race/ethnicity. It demonstrates the interpretation of item-level partial non-invariance results and their implications for group-level differences and encourages substantive theorizing regarding measurement fairness.
This Element provides a systematic overview and synthesis of corpus-based research into collocations focusing on the learning and use of collocations by second language (L2) users. Underlining the importance of collocation as a key notion within the field of corpus linguistics, the text offers a state-of-the-art account of the main findings related to the applications of corpora and corpus-based measures for defining, identifying and analysing collocations as related to second language acquisition. Emphasising the quality of L2 collocation research, the Element illustrates key methodological issues to be considered when conducting this type of corpus analysis. It also discusses examples of pertinent research questions and points to representative studies treated as models of good practice. Aiming at researchers both new and experienced, the Element also points to avenues for future work and shows the relevance of corpus-based analysis for improving the process of learning and teaching of L2 collocations.
As evidence of our global survival crisis continues to mount, the expression 'too little, too late' comes to mind. We all live in an interdependent world which has an increasingly shared fate. We are participants in an emerging global 'superorganism' that is dependent on close cooperation. Indeed, positive synergy (cooperative effects) has been the key to our evolutionary success as a species. However, our ultimate fate is now in jeopardy. Going forward, we must either create a more effective global society (with collective self-governance) or our species will very likely be convulsed by mass starvation, waves of desperate migrants, and lethal social conflict. The greatest threat we may face is each other, and a regression into tribalism and violent conflict. This Element has a more hopeful prescription for a new global social contract. It is based on the many examples of superorganisms – socially organized species – in the natural world, and in evolution.
The rise of monotheistic religious faith in ancient Israel and post-exilic Judaism inspired the imperative for social justice on behalf of the poor and the oppressed. Though some authors have maintained that monotheism inspires tyranny, this author maintains that real monotheistic faith affirms justice and human equality. This can be evidenced by a consideration of the Old Testament prophets and Law. Especially with the law we may observe a progression in the attempt to provide increasing rights for the poor and the oppressed.
Construction Grammar (CxG) has developed into a broad and highly diverse family of approaches that have in common that they see constructions, i.e. form-meaning pairs at various levels of abstraction and complexity, as the basic units of language. This Element gives an overview of the origin and the current state of the art of constructionist approaches, focusing, on the one hand, on basic concepts like the notion of 'constructions', while at the same time offering an in-depth discussion of current research trends and open questions. It discusses the commonalities and differences between the major constructionist approaches, the organization of constructional networks as well as ongoing research on linguistic creativity, multimodality and individual differences. This title is also available as Open Access on Cambridge Core.
This is a love story but not as you know it. Should an academic study be framed in this way? Love seems an unlikely bedfellow for critical thinking. Watching an Emma Rice production and being in her rehearsal room you feel the love: a warm and generous welcoming in; a joyful celebration of the theatrical exchange. What produces this pleasurable affect and how might we consider its political potential? This Element positions Emma's theatre-making, a body of work spanning three decades, as feminist acts of love. Drawing on fieldwork research her practice is viewed through the critical lenses of feminisms and affect to consider its contextual tensions, its ethics of affirmation, staging of femininities and contribution to queer worldmaking. Mapping her work from this perspective brings to light her important contribution to UK feminist theatre; its love activism offering an emergent strategy for change.
The Renaissance was a highly mobile, turbulent era in Europe, when war, poverty, and persecution pushed many people onto the roads in search of a living or a safe place to settle. In the same period, the expansion of European states overseas opened up new avenues of long-distance migration, while also fuelling the global traffic in slaves. The accelerating movement of people stimulated commercial, political, religious, and artistic exchanges, while also prompting the establishment of new structures of control and surveillance. This Element illuminates the material and social mechanisms that enacted mobility in the Renaissance and thereby offers a new way to understand the period's dynamism, creativity, and conflict. Spurred by recent 'mobilities' studies, it highlights the experiences of a wide range of mobile populations, paying particular attention to the concrete, practical dimensions of moving around at this time, whether on a local or a global scale.
This Cambridge Elements on Global Development Studies volume applies the lens of 'investor state' to a pattern of cross-border activities emerging at the end of aid. Using a series of case studies, the volume examines the growth of a trend where states operate as, with and for investors in the healthcare provision sectors of other nations. It sheds light on an evolving institutional landscape for global health in which state-owned development finance institutions, national development banks and sovereign wealth funds are becoming key financial stakeholders in healthcare systems. The trend has been gathering pace in the past 10-15 years in contexts of growing diversity for development financing and is driving the expansion of corporate-oriented models for healthcare provision that are liable to undermine already-strained progress towards achieving equitable access in healthcare globally.
This Element is about the creation and curation of social memory in pharaonic and Greco-Roman Egypt. Ancient, Classical, Medieval, and Ottoman sources attest to the horror that characterized catastrophic famines. Occurring infrequently and rarely reaching the canonical seven-years' length, famines appeared and disappeared like nightmares. Communities that remain aware of potentially recurring tragedies are often advantaged in their efforts to avert or ameliorate worst-case scenarios. For this and other reasons, pharaonic and Greco-Roman Egyptians preserved intergenerational memories of hunger and suffering. This Element begins with a consideration of the trajectories typical of severe Nilotic famines and the concept of social memory. It then argues that personal reflection and literature, prophecy, and an annual festival of remembrance functioned-at different times, and with varying degrees of success-to convince the well-fed that famines had the power to unseat established order and to render a comfortably familiar world unrecognizable.
The study of terrorism represents one of the major turning points in criminology of the twenty-first century. In the space of just two decades, research on terrorism and political extremism went from a relatively uncommon niche to a widely recognized criminological specialization. Terrorism research now appears in nearly all mainstream criminology journals; college courses on terrorism and political violence have been added to the curricula of most criminology departments; and a growing number of criminology students are choosing terrorism as a suitable topic for class papers, research topics, theses and dissertations. The purpose of this book is to explore similarities and differences between terrorism and more ordinary forms of crime. This Element considers the ways that criminology has contributed to the study of terrorism and the impact the increasing interest in terrorism has had on criminology. This Element also provides empirical comparisons of terrorist attacks to more ordinary crimes and criminal offenders. This title is also available as Open Access on Cambridge Core.
Everything we know about Shakespeare – his world, his words, his work – is preconceived by print. This knowledge extends to cultural expressions that seek to evade ink, paper, and moveable type, such as performance, such as acting. Print privileges qualities quite alien to performance, however: standardization, reproducibility, and, above all, uniformity. Thus the master tropes of print occlude rather than clarify our thinking about acting. How might we think about Shakespeare and performance without print? Examining texts both early and modern, Shakespeare without Print contends that Shakespeare and performance has long been dominated by a medium alien to its expression, print, a foreign government that forecloses alternative conceptualizations and practices. Through a series of discrete but linked excursions into the relationship between Shakespearean print and Shakespearean performance, this Element auditions alternative prepositions to enfranchise scholars and practitioners from print, which currently binds and determines our various approaches to Shakespearean performance.
The UK has been collaborating with international, primarily European partners in the design, development and production of advanced combat aircraft for over sisty years. Driven by a combination of rising costs and limited domestic markets, collaboration has also been a highly political act involving a combination of national, industrial and technological interests. Over the years, the form of collaboration has evolved, in some cases leading to the creation of transnational companies. The UK has been a pioneer of globalisation in the defence industry, establishing a strong presence inside the US defence market and has become a significant partner with American companies in key military aerospace programmes. This has contributed to divisions within the European military aerospace industry which are likely to continue into the next generation of combat aircraft.
Internet memes are recognised for their role in creating community through shared humour or in-group cultural knowledge. One category of meme uses historical art pieces, coupled with short texts or dialogue, as a form of social commentary on both past and present. These memes often rely on a (mis)reading of the emotions of those represented in such artwork for humorous purposes. As such, they provide an important example of transhistorical engagement between contemporary society and past artifacts centred on the nature of emotion. This Element explores the historical art meme as a key cultural form that offers insight into contemporary online emotional cultures and the ways that historical emotions enable and inform the practices of such culture. It particularly attends to humour as a mode which helps to mediate the disjuncture between past and present emotion and which enables historical emotion to 'do' political and community-building work amongst meme users.
