The value of great leaders seems to be an unquestioned assumption. The goal of this Element is to explore the counterintuitive idea that great leaders can pose a hazard to themselves and their followers. Great leadership, which accomplishes morally commendable and difficult objectives by leaders and followers, requires competence, morality, and charisma. A hazard is a condition or event that leads to human loss, such as injury, death, or economic misfortune. A leader can become a hazard through social psychological processes, which operate through the metaphor of Seven Deadly Sins, to create negative consequences. Great leaders can undermine their own success and accomplishments, as well as their followers. They can become a threat to the organization in which they are employed. Finally, great leaders can become a danger to the larger society. The damage great leaders can create can be reduced by applying the corresponding virtue.

In this Element, the authors consider fully discretized p-Laplacian problems (evolution, boundary value and variational problems) on graphs. The motivation of nonlocal continuum limits comes from the quest of understanding collective dynamics in large ensembles of interacting particles, which is a fundamental problem in nonlinear science, with applications ranging from biology to physics, chemistry and computer science. Using the theory of graphons, the authors give a unified treatment of all the above problems and establish the continuum limit for each of them together with non-asymptotic convergence rates. They also describe an algorithmic framework based proximal splitting to solve these discrete problems on graphs.

Celebrated as an actress on the London stage (1776–80) and notorious as the mistress of the Prince of Wales (1779–80), Mary Darby Robinson had to write to support herself from the mid–1780s until her death in 1800. She mastered a wide range of styles, published prolifically, and became the poetry editor of the Morning Post. As her writing developed across the 1790s, she increasingly used the motifs of Gothic fiction and drama descended from Horace Walpole's Castle of Otranto (1764). These came to pervade her late novels and poems so much that she even wrote her autobiography as a Gothic romance. She also deployed them to critique the ideologies of male dominance and the forms of writing in which they appeared. This progression culminated in her final collection of verses, Lyrical Tales (1800), where she Gothically exposes the conflicted underpinnings in the now-famous Lyrical Ballads (1798) by Wordsworth and Coleridge.

This Element provides an overview of pre-modern and ancient economies of the Pacific Northwest region of North America. The region is widely known for its densely occupied semisedentary villages, intensive production economies, dramatic ritual life, and complex social relations. Scholars recognize significant diversity in the structure of subsistence and goods production in the service of domestic groups and institutional entities throughout the region. Here, domestic and institutional economies, specialization, distribution, economic development, and future directions are reviewed. The Element closes with thoughts on the processes of socio-economic change on the scales of houses, villages, and regional strategies.

In this Element, the authors introduce and apply a framework for the linguistic analysis of fake news. They define fake news as news that is meant to deceive as opposed to inform and argue that there should be systematic differences between real and fake news that reflect this basic difference in communicative purpose. The authors consider one famous case of fake news involving Jayson Blair of The New York Times, which provides them with the opportunity to conduct a controlled study of the effect of deception on the language of a single reporter following this framework. Through a detailed grammatical analysis of a corpus of Blair's real and fake articles, this Element demonstrates that there are clear differences in his writing style, with his real news exhibiting greater information density and conviction than his fake news.

The question of whether coercion is a necessary or contingent feature of governance by law is a historically complex aspect of a venerable 'modalist' trend in jurisprudential thinking. The nature of the relation between law and coercion has been elaborated by means of a variety of modally qualified accounts, all converging in a more or less committing response to whether the language, concept or essence of law as a system of governance necessarily entails the coercive character of this system. This Element remodels in non-modal terms the way in which legal philosophers can meaningfully disagree about the coercive character of governance by law. On this alternative model, there can be no meaningful disagreement about whether law is coercive without prior agreement on the contours of a theory of how law is made.

The extraxial-axial theory (EAT) and universal elemental homology (UEH) are often portrayed as mutually exclusive hypotheses of homology within pentaradiate Echinodermata. EAT describes homology upon the echinoderm bauplan, interpreted through early post-metamorphic growth and growth zones, dividing it into axial regions generally associated with elements of the ambulacral system and extraxial regions that are not. UEH describes the detailed construction of the axial skeleton, dividing it into homologous plates and plate series based on symmetry, early growth, and function. These hypotheses are not in conflict; the latter is rooted in refinement of the former. Some interpretive differences arise because many of the morphologies described from eleutherozoan development are difficult to reconcile with Paleozoic forms. Conversely, many elements described for Paleozoic taxa by UEH, such as the peristomial border plates, are absent in eleutherozoans. This Element recommends these two hypotheses be used together to generate a better understanding of homology across Echinodermata.

Although early-life adversity can undermine healthy development, an evolutionary-developmental perspective implies that children growing up in harsh environments will develop intact, or even enhanced, skills for solving problems in high‐adversity contexts (i.e., 'hidden talents'). This Element situates the hidden talents model within a larger interdisciplinary framework. Summarizing theory and research on hidden talents, it proposes that stress-adapted skills represent a form of adaptive intelligence enabling individuals to function within the constraints of harsh environments. It discusses potential applications of this perspective to multiple sectors concerned with youth from harsh environments, including education, social services, and juvenile justice, and compares the hidden talents model with contemporary developmental resilience models. The hidden talents approach, it concludes, offers exciting directions for research on childhood adversity, with translational implications for leveraging stress-adapted skills to more effectively tailor education, jobs, and interventions to fit the needs of individuals from a diverse range of life circumstances.

In the Global South economic mobility across generations or intergenerational economic mobility is in and of itself an important topic for research with consequences for policy. It concerns the 'stickiness' or otherwise of inequality because mobility is concerned with the extent to which children's economic outcomes are dependent on their parents' economic outcomes. Scholars have estimated levels of intergenerational mobility in many developed countries. Fewer estimates are available for developing countries, where mobility matters more due to starker differences in living standards. This Element surveys the area, conceptually and empirically; it presents a new estimate for a developing country, namely Indonesia; it discusses the 'Great Gatsby Curve' and highlights the different positions of developed and developing countries. Finally, it presents a theoretical framework to explain the drivers of mobility and the stickiness or otherwise of inequality across time.

As we understand them, dispositions are relatively uncontroversial 'predicatory' properties had by objects disposed in certain ways. By contrast, powers are hypothetical 'ontic' properties posited in order to explain dispositional behaviour. Chapter 1 outlines this distinction in more detail. Chapter 2 offers a summary of the issues surrounding analysis of dispositions and various strategies in contemporary literature to address them, including one of our own. Chapter 3 describes some of the important questions facing the metaphysics of powers including why they're worth positing, and how they might metaphysically explain laws of nature and modality.

Causal inference and machine learning are typically introduced in the social sciences separately as theoretically distinct methodological traditions. However, applications of machine learning in causal inference are increasingly prevalent. This Element provides theoretical and practical introductions to machine learning for social scientists interested in applying such methods to experimental data. We show how machine learning can be useful for conducting robust causal inference and provide a theoretical foundation researchers can use to understand and apply new methods in this rapidly developing field. We then demonstrate two specific methods – the prediction rule ensemble and the causal random forest – for characterizing treatment effect heterogeneity in survey experiments and testing the extent to which such heterogeneity is robust to out-of-sample prediction. We conclude by discussing limitations and tradeoffs of such methods, while directing readers to additional related methods available on the Comprehensive R Archive Network (CRAN).

The international architecture of peacebuilding and statebuilding is currently responding to a shift from 'analogue' to 'digital' approaches in international relations. This is affecting conflict management, intervention, peacebuilding, and the all-important role of civil society. This Element analyses the potential that these new digital forms of international relations offer for the reform of peace praxis – namely, the enhancement of critical agency across networks and scales, the expansion of claims for rights and the mitigation of obstacles posed by sovereignty, locality, and territoriality. The Element also addresses the parallel limitations of digital technologies in terms of political emancipation related to subaltern claims, the risk of co-optation by historical and analogue power structures, institutions, and actors. We conclude that though aspects of emerging digital approaches to making peace are promising, they cannot yet bypass or resolve older, analogue conflict dynamics revolving around power-relations, territorialism, and state formation.

The inherent paradox of Egyptology is that the objective of its study – people living in Egypt in Pharaonic times – are never the direct object of its studies. Egyptology, as well as archaeology in general, approach ancient lives through material (and sometimes immaterial) remains. This Element explores how, through the interplay of things and people – of non-human actants and human actors – Pharaonic material culture is shaped. In turn, it asks how, through this interplay, Pharaonic culture as an epistemic entity is created: an epistemic entity which conserves and transmits even the lives and deaths of ancient people. Drawing upon aspects of Actor Network Theory, this Element introduces an approach to see technique as the interaction of people and things, and technology as the reflection of these networks of entanglement.

This Element proposes a clear and up-to-date description of the state of artificial intelligence today, not only in terms of business processes and strategies, but also its societal reception. It presents our view of the technology landscape, avoiding both the forward-looking, rose-colored utopia and the hyper-apocalyptic gloom. It does so in a concise form, addressing a complex issue in 9 concise and easy-to-read chapters. It aims to discuss the current state of machine learning and AI in strategic management, and to describe the emerging technologies. It conceptualizes their adoption, and then consider the effects of AI technologies' maturity in business organizations.

The breadth and spread of corpus-assisted discourse studies (CADS) indicate its usefulness for exploring language use within a social context. However, its theoretical foundations, limitations, and epistemological implications must be considered so that we can adjust our research designs accordingly. This Element offers a compact guide to which corpus linguistic tools are available and how they can contribute to finding out more about discourse. It will appeal to researchers both new and experienced, within the CADS community and beyond.

This Element offers a novel, highly relevant perspective towards Multilateral Development Banks (MDBs), which are development and financial organizations at the same time. Based on the elaborate institutional logics perspective borrowed from organizational sociology, it uncovers the complex trade-offs between financial and development pressures faced by MDBs and explains variation in organizational responses thereto across types of MDBs. The argument is tested with an original dataset using Data Envelopment Analysis to explain variation in response patterns across MDBs. The analysis shows that lending to the private sector as well as being predominantly owned by borrowing members increase MDBs' emphasis on the financial at the expense of the development nature. Thereby, this Element provides unique insights into MDBs' responses to their dual nature and significantly advances our understanding of MDB lending operations, drawing attention to the complexities involved in the unique MDB business model.

This Will Not Be Generative attends to the semiotics of ecological writings via Caribbean literary studies and black critical theory. Closely reading texts by Donna Haraway, Monique Allewaert, and Lisa Wells, it exposes how the language of tentacles and tendrils, an assumptive 'we,' and redemptive sympathy or 'care' disguises extraction from black people and blackness. This often speculative rhetoric, abetted by fantasies of white communion with indigenous groups, contrasts with the horror semiotics of the films Get Out (2017) and Midsommar (2019), which unmask the antagonistic relationship between white survival 'at the end of the world' and blackness as compost.

Apparent contradiction is common in traditional monotheism, and perhaps especially so in standard Christian theology given central doctrines such as the incarnation and trinity. This Element aims to chart out a very elementary but abstract framework through which such contradictions may be approached. This Element does not attempt to address the many options for thinking about contradictions in the face of logical entailment; it charts only a few salient abstract options.

Over the past decade, attribution scholars have come to a consensus that Shakespeare wrote some of the additions printed in the 1602 quarto of Kyd's Spanish Tragedy. This new development in textual studies has far-reaching consequences for established theatre-historical narratives. Accounting for Shakespeare's involvement in The Spanish Tragedy requires us to rethink the history of two major theatre companies, the Admiral's and the Chamberlain's Men, and to reread much of the documentary record of late Elizabethan theatre. Modelling what a theatre-historical response to new attributionist arguments might look like, the author offers an in-depth reinterpretation of Philip Henslowe's records of new plays, develops a novel account of how theatre companies copied and adapted plays in one another's repertories (including a reconsideration of the 'Ur-Hamlet' and the two Shrew plays), and reconstructs an early modern cluster of Hieronimo plays that also allows us to reimagine Ben Jonson's career as an actor.

This Element presents science-engaged theology as a reminder to theologians to use the local tools and products of the sciences as sources for theological reflection. Using critiques of modernity and secularism, the Element questions the idea that Science and Religion were ever transhistorical categories. The Element also encourages theologians to collaborate with colleagues in other disciplines in a highly localised manner that enables theologians to make concrete claims with accountability and show how theological realities are entangled with the empirical world.
