This Element presents an integrated account of psychodrama theory, practice, and research. It begins by exploring psychodrama's psychosocial roots and emphasizes Jacob Levy Moreno's pioneering work. Core concepts such as spontaneity, creativity, adaptability, encounter, act-hunger, action insight, and act fulfillment are discussed in detail. This is followed by an overview of psychodrama practice, including session structure, core techniques, and a positive psychodrama intervention program. Five research designs for outcome studies are presented, along with key issues such as bias assessment, treatment fidelity, treatment differentiation, feasibility, and acceptability in psychodrama research. Change process research is reviewed in light of the latest evidence and methods, highlighting eleven therapeutic change factors in psychodrama and discussing concepts such as moderation, mediation, and mechanisms of change. The final section addresses future directions, including nonverbal synchrony and physiological and neurobiological pathways in psychodrama research.

This Element reports on the creation and analysis of a 1.5-million-word corpus consisting of a year's worth of UK national press news articles about Islam and Muslims, published between December 2022 and November 2023. The corpus also contains 8,546 image files which have been automatically tagged using Google's Vertex AI. Analysis was carried out on three levels a) written text only, b) images only, c) interactions between written text and images. Using examples from the analyses, the authors demonstrate the affordances of these three approaches, providing a critical evaluation of Vertex AI's capabilities and the abilities of popular corpus software to work with visually tagged corpora. The Element acts as a practical guide for researchers who want to carry out this form of analysis. This title is also available as Open Access on Cambridge Core.
Using audit to identify where improvement is needed and providing feedback to healthcare professionals to encourage behaviour change is an important healthcare improvement strategy. In this Element, the authors review the evidence base for using audit and feedback to support improvement, summarising its historical origins, the theories that guide it, and the evidence that supports it. Finally, the authors review limitations and risks with the approach, and outline opportunities for future research. This title is also available as open access on Cambridge Core.
Climate impacts and risk, within and across cities, are distributed highly unequally. Cities located in low latitudes are more vulnerable to climate risk and impacts than in high latitudes, due to the large proportion of informal settlements relative to the housing stock and more frequent extremes. According to EM-DAT, about 60% of environmental disasters in cities relate to riverine floods. Riverine floods and heatwaves cause about 33% of deaths in cities. However, cold-waves and droughts impact most people in cities (42% and 39% of all people, respectively). Human vulnerability intersects with hazardous, underserved communities. Frequently affected groups include women, single parents, and low-income elderly. Responses to climatic events are conditioned by the informality of social fabric and institutions, and by inequitable distribution of impacts, decision-making, and outcomes. To ensure climate-resilient development, adaptation and mitigation actions must include the broader urban context of informality and equity and justice principles.

Organisms are central for biology. However, conceptualizing the unit of the organism is not easy. This Element discusses challenges to base biological reasoning and practice on the concept of organism. After many decades dominated by the paradigm of the gene, the organism is making a comeback in the bio- and biomedical sciences. It is again recognized as a causally efficacious, autonomous, and active unit that transcends the properties of genes and affects its own development and evolution – especially in fields like epigenetics, niche construction theory, and evolutionary developmental biology. This Element investigates these developments from a perspective of integrated history and philosophy of science. It focuses on conceptual, biotheoretical, and historical dimensions, as well as sociopolitical and anthropological aspects of today's 'return of the organism.' In particular, it discusses solutions for challenges of organism-centered biosciences in the 21st century. This title is also available as Open Access on Cambridge Core.
This Element advances a novel view – the Epistemic Labour View – about the role, limits, and potential of the theoretical virtues as the arbiters of various versions of underdetermination. A central focus is to go beyond the often abstract discussions in this area and to show how the theoretical virtues can illuminate and resolve issues surrounding actual cases of underdetermination found in scientific practice.

In many areas experiencing severe impacts from climate change, it is not the state, but rather rebel groups who wield authority over populations. Rebels are often engaged in responding and adapting to the risks and impacts of climate change as part of their local governance efforts; however, a systematic consideration of the activities and implications has been lacking. This Element looks at a set of behaviors we call “rebel environmental governance” (REG+). This refers to rebel actions aimed at protecting or managing the natural environment to affect civilian welfare amidst increasing pressures of climate change. A framework is advanced for understanding why rebels engage in environmental governance and the implications for security and climate governance. The Element brings rebel organizations into the conversation on climate change, highlighting their role in areas where state power is contested, weak, or absent.

This Element tells the twenty-year socio-legal story of human rights-based climate change litigation. Based on an original database of the totality of rights-based climate change (RCC) lawsuits around the world as well as interviews with leading actors and participant observation in the field, the Element explains the rise and global diffusion of RCC litigation. It combines insights from global governance, international law, climate policy, human rights, and legal mobilization theory in order to offer a socio-legal account of the actors, strategies, and norms that have emerged at the intersection of human rights and climate governance. By proposing a broad understanding of the impacts of legal mobilization that includes direct and indirect, material and symbolic effects, it documents the contributions and shortcomings of human rights litigation in addressing the climate emergency.

Critics of populism and advocates of elitist democracy often place greater confidence in political elites than in the general public. However, this trust may be misplaced. In five experiments with local politicians, state legislators, and members of the public, the author finds a similar willingness across all groups to entrench their party's power when given the opportunity – a self-serving majoritarianism that transcends partisan lines. This tendency is strongest among committed ideologues, politicians running in highly competitive districts, and those who perceive opponents as especially threatening. Local elected officials even appear more focused on securing their party's next presidential victory than on opposing bans against their political rivals. These findings challenge the conventional mass/elite dichotomy, revealing little differences in undemocratic attitudes. Safeguarding democracy likely requires shifting focus from those individual attitudes to strengthening institutional restraints against majority abuses.

This Element derives subjective poverty lines for seven Latin American countries based on a Minimum Income Question included in household expenditure surveys. It compares poverty incidence under the subjective and objective approach, finding subjective poverty is larger than objective for all countries. People identified as poor are generally poor by both measures or only subjective poor, although patterns of overlapping differ between countries. It explores the factors associated to considering oneself as poor - being subjectively poor- when the per capita household income is higher than the objective poverty line. Generally, unemployment and informality are associated with higher probability of subjective poverty. Other factors not directly involving income but reflecting high economic security also tend to reduce the probability of feeling poor. Finally, the welfare stigma effect does not seem to hold, at least in terms of subjective poverty. This title is also available as Open Access on Cambridge Core.
Addresses the role of structure in semantic analysis from the perspective of theories of meaning using rich theories of types. Also relates the theory of frames to these type theories as introducing, to some extent, similar structure into semantic analysis. The authors show how a structured approach is necessary to appropriately analyse phenomena in areas as diverse as lexical semantics and the semantics of attitudinal constructions referring to psychological states. In particular, these are: polysemy taken together with copredication, and attitudes such as belief and knowledge. The authors argue that the very same structure required to define a rich system of types enables them to adequately analyse both of these phenomena, thus revealing similarities in two otherwise apparently unrelated topics in semantics. They also argue that such theories facilitate a semantic theory oriented towards a psychological and contextually situated view of meaning.

Just as councils and assemblies were central to European polities for centuries, the Imperial Examination System (Keju) constituted the cornerstone of state institutions in China. This Element argues that Keju contributed to political stability, and its emergence was a process, not a shock, with consequences initially unanticipated by its contemporaries. The Element documents the emergence of Keju using evidence from early Chinese empires to the end of the Tang Dynasty in the 10th century, including epitaphs and government documents. It then traces the selection criteria of Keju and trends in social mobility over the second millennium, leveraging biographical information from over 70,000 examinees and 1,500 ministers and their descendants. The Element uses a panel of 112 historical polities to quantify Keju's association with country-level political indicators against the backdrop of global convergence in political stability and divergence in institutions.

In a perfect market economy, the cost of raising another euro of tax revenue equals one. However, once distortionary taxes on goods and factors are introduced, the marginal cost of public funds, MCPF, typically deviates from one. Often it exceeds one, but one can also find cases where it falls short of one. This Element introduces the concept of the MCPF, sketches its history, and discusses a number of applications. It does this by undertaking economic evaluations of public sector projects involving a pure public good. An important distinction in the literature relates to where the government has access to lump-sum taxation versus where it must rely on changing a distortionary tax. These are often unit taxes or proportional taxes. Sometimes they are even introduced to alleviate a problem. An example is a tax on emissions of greenhouse gases.

String diagrams are a powerful graphical language used to represent computational phenomena across diverse scientific fields, including computer science, physics, linguistics, amongst others. The appeal of string diagrams lies in their multi-faceted nature: they offer a simple, visual representation of complex scientific ideas, while also allowing rigorous mathematical treatment. Originating in category theory, string diagrams have since evolved into a versatile formalism, extending well beyond their abstract algebraic roots, and offering alternative entry points to their study. This text provides an accessible introduction to string diagrams from the perspective of computer science. Rather than starting from categorical concepts, the authors draw on intuitions from formal language theory, treating string diagrams as a syntax with its own semantics. They survey the basic theory, outline fundamental principles, and highlight modern applications of string diagrams in different fields. This title is also available as open access on Cambridge Core.
Shared leadership entails a dynamic, interactive influence process among groups and teams. Whereas traditional models of leadership emphasize the importance of vertical leadership as a role occupied by an individual in a designated position, shared leadership emphasizes the importance of leadership as an unfolding social process, shifting the influence to the person with the most relevant knowledge, skills and abilities, juxtaposed against the emerging task related requirements. Research shows that shared leadership is a robust predictor of group, team and organizational outcomes across a variety of organizations, industries and cultural contexts. In fact, shared leadership is a better predictor of outcomes than vertical leadership. This Element provides a comprehensive review of the research on shared leadership, and points to promising directions for the future, in terms of both research and the practical application of shared leadership in action.

Microsystems are the building blocks of the healthcare system. They are the small functional frontline units that provide most healthcare to most people, be it a clinic or a ward. The microsystem improvement approach engages teams at the frontline of care with patients and families in a structured process to improve the quality of care and outcomes. This Element offers an overview of the theory of the microsystems, mesosystems, and team coaching improvement approaches, using case studies to demonstrate how the approaches have been used in practice. A critique of the emerging evidence base and the strengths and limitations of the approach is given. This title is also available as open access on Cambridge Core.
This Element delves into the relationship between logic and the sciences, a topic brought to prominence by Quine, who regarded logic as methodologically and epistemologically akin to the sciences. For this reason, Quine is seen as the forefather of anti-exceptionalism about logic (AEL), a stance that has become prevalent in the philosophy of logic today. Despite its popularity and the volume of research it inspires, some core issues still lack clarity. For one thing, most works in the debate remain vague on what should count as logic and what should count as a science. Furthermore, the terms of the comparison are rarely specified and discussed in a systematic way. This Element purports to advance the debate on these crucial issues with the hope of fostering our understanding of the fundamentals of AEL.

This Element studies how career support from romantic partners affects career patterns and costs in politics. It argues that a lower level of career support from romantic partners leads to a lower likelihood for political promotion among women politicians (the partner support hypothesis), as well as greater stress on women politicians' relationships when they advance (the career stress hypothesis). Both predictions find support in Swedish data for more than 80,000 political careers over a fifty-year period. Women politicians are in relationships that prioritize their male partner's career and where that partner does less unpaid work in the household. This is important in explaining women's career disadvantage. It also explains why promotions double the divorce rate for women but leave men's relationships intact. The analysis sheds light on the role played by romantic partners in gender inequality in politics. This title is also available as Open Access on Cambridge Core.
Policy studies assume the existence of baseline parameters – such as honest governments doing their best to create public value, publics responding in good faith, and both parties relying on a policy-making process which aligns with the public interest. In such circumstances, policy goals are expected to be produced through mechanisms in which the public can articulate its preferences and policy-makers are expected to listen to what has been said in determining their governments' courses of action. While these conditions are found in some governments, there is evidence from around the world that much policy-making occurs without these pre-conditions and processes. Unlike situations which produce what can be thought of as 'good' public policy, 'bad' public policy is a more common outcome. How this happens and what makes for bad public policy are the subjects of this Element. This title is also available as Open Access on Cambridge Core.
Social ontology is the study of the nature of the social world. This Element aims to provide an overview of this burgeoning field, and also to map the questions that theories in social ontology address. When we encounter a theory of some social thing – groups, law, gender, and so on –how are we to read it? What classes of theories have been explored and abandoned, and what classes are new and promising? The Element distinguishes theories of social construction from theories that characterize the products of social construction. For each, the Element works through a 'toy' theory and then discusses features that more realistic theories ought to include. Three running examples are discussed throughout the Element: (1) property, or ownership; (2) race, or racialized kinds; (3) collective attitudes (i.e., beliefs, desires, knowledge, intentions, etc., of groups and organizations).
