Operational research is a collection of modelling techniques used to structure, analyse, and solve problems related to the design and operation of complex human systems. While many argue that operational research should play a key role in improving healthcare services, staff may be largely unaware of its potential applications. This Element explores operational research's wartime origins and introduce several approaches that operational researchers use to help healthcare organisations: address well-defined decision problems; account for multiple stakeholder perspectives; and describe how system performance may be impacted by changing the configuration or operation of services. The authors draw on examples that illustrate the valuable perspective that operational research brings to improvement initiatives and the challenges of implementing and scaling operational research solutions. They discuss how operational researchers are working to surmount these problems and suggest further research to help operational researchers have greater beneficial impact in healthcare improvement.

This Element introduces and critically reflects on the contribution of implementation science to healthcare improvement efforts. Grounded in several disciplines, implementation science is the study of strategies to promote the uptake of evidence-based interventions into healthcare practice and policy. The field's focus is threefold. First, it encompasses theory and empirical research focused on exploring, identifying, and understanding the systems, behaviours, and practices that influence successful implementation. Second, it examines the evaluation of strategies to address barriers or enablers to implementation in a given context. Last, it increasingly seeks to understand the process of implementation itself: what actually gets implemented, and when, why, and how? Despite the growing body of evidence, challenges remain. Many important messages remain buried in the literature, and their impact on implementation efforts in routine practice may be limited. The challenge is not just to get evidence into practice, but also to get implementation science into practice. This title is also available as Open Access on Cambridge Core.
Substance has long been one of the key categories in metaphysics. This Element focuses on contemporary work on substance, and in particular on contemporary substance ontologies, metaphysical systems in which substance is one of the fundamental categories and individual substances are among the basic building blocks of reality. The topics discussed include the different metaphysical roles which substances have been tasked with playing; different critieria of substancehood (accounts of what is it to be a substance); arguments for and against the existence of substances; and different accounts of which entities, if any, count as substances.
Healthcare policy frequently invokes notions of cultural change as a means of achieving improvement and good-quality care. This Element unpacks what is meant by organisational culture and explores the evidence for linking culture to healthcare quality and performance. It considers the origins of interest in managing culture within healthcare, conceptual frameworks for understanding culture change, and approaches and tools for measuring the impact of culture on quality and performance. It considers potential facilitators of successful culture change and looks forward towards an emerging research agenda. As the evidence base to support culture change is rather thin, a more realistic assessment of the task of cultural transformation in healthcare is warranted. Simplistic attempts to manage or engineer culture change from above are unlikely to bear fruit; rather, efforts should be sensitive to the complexity and highly stratified nature of culture in an organisation as vast and diffuse as the NHS.

Much has been written on the relationship between the nature of temporal reality and the God of Classical Theism. Despite the popularity of this general area, what the physics and metaphysics of spacetime might mean for specific theological doctrines has received less attention. Recently, however, interest in this rich and dynamic interplay of ideas has seen rapid growth. This Element provides both an introduction to the physics and metaphysics of spacetime and a jumping-off point for understanding how these can – and in fact should – inform both Christian theology and the philosophy of religion more generally. The author will argue that the nature of spacetime raises particular and pressing problems for Christianity, specifically the interrelated doctrines of salvation and eschatology, and explore whether adequate solutions to these problems are available.
The idea of progress is a product of historical thinking. It is a bold interpretation of history that combines understandings of the past, perceptions of the present and expectations of the future. This Element examines the shifting scale of this past, present and future configuration from antiquity to the present day. It develops five categories that reveal the conceptual features of progress together with the philosophies of history in which they have been enmeshed, from temporal outlooks that held no notion of progress to universal histories that viewed progress as a law of nature, from speculation on the meaning and direction of history to the total rejection of all historical constructions. Global in scope and conversant with present-day debates in the theory and philosophy of history, the argument throughout is that the scale on which we conceive history plays a determining role in how we think about progress.
This Element introduces the concept of oligopoly of coercion to interpretate the interaction between drug trafficking and reconfiguration of the state in Colombia. Three elements are central to this interpretation: corruption in oligopolies of coercion must be understood as a payment by drug traffickers for acting like a parallel state; the state criminalizes more drug as merchandise than drug as capital – its equivalent in money; the politics and war around drug trafficking in Colombia should be understood as the way in which peripheral societies access global markets through the ruling institutions of private armies. With these elements, the author focuses on the dynamics of the reconfiguration of the state in Colombia after the cocaine boom in the mid-70s and the evolution of the private armies in Colombia.
This is an Element about some of the largest sites known in prehistoric Europe – sites so vast that they often remain undiscussed for lack of the theoretical or methodological tools required for their understanding. Here, the authors use a relational, comparative approach to identify not only what made megasites but also what made megasites so special and so large. They have selected a sample of megasites in each major period of prehistory – Neolithic, Copper, Bronze and Iron Ages – with a detailed examination of a single representative megasite for each period. The relational approach makes explicit comparisons between smaller, more 'normal' sites and the megasites using six criteria – scale, temporality, deposition / monumentality, formal open spaces, performance and congregational catchment. The authors argue that many of the largest European prehistoric megasites were congregational places.
This Element examines the early years of British Young Adult (YA) publishing at three strategic publishing houses: Penguin, Heinemann and Macmillan. Specifically, it discusses their YA imprints (Penguin Peacocks, Heinemann New Windmills and Macmillan Topliners), all created at a time when the population of Britain was changing and becoming more diverse. Migration of colonial and former colonial subjects from the Caribbean, India, and Africa contributed to a change in the ethnic makeup of Britain, especially in major urban centres such as London, Birmingham and Manchester. While publishing has typically been seen as slow to respond to societal changes in children's literature, all three of these Young Adult imprints attempted to address and include Black British and British Asian readers and characters in their books; ultimately, however, their focus remained on white readers' concerns.
In less than half a century (1978–2020), China has transformed itself from a country that barely fed itself to a powerful player in the global food system, characterized by massive food imports, active overseas agricultural engagement, and the global expansion of Chinese agribusiness. This Element offers a nuanced analysis of China's global food strategy and its impacts on food security and the international agri-food order. To feed a population of 1.4 billion, China actively seeks overseas agri-food resources whilst maintaining a high level of domestic food production. This strategy gives China an advantageous position in the global food system, but it also creates contradictions and problems within and beyond the country. This could potentially worsen global food insecurity in the long term.
Does interpersonal political communication improve the quality of individual decision making? While deliberative theorists offer reasons for hope, experimental researchers have demonstrated that biased messages can travel via interpersonal social networks. We argue that the value of interpersonal political communication depends on the motivations of the people involved, which can be shifted by different contexts. Using small-group experiments that randomly assign participants' motivations to seek or share information with others as well as their motivations for evaluating the information they receive, we demonstrate the importance of accounting for motivations in communication. We find that when individuals with more extreme preferences are motivated to acquire and share information, collective civic capacity is diminished. But if we can stimulate the exchange of information among individuals with stronger prosocial motivations, such communication can enhance collective civic capacity. We also provide advice for other researchers about conducting similar group-based experiments to study political communication.
Cinderella's Glass Slipper studies Renaissance material cultures through the literary prism of fairy-tale objects. The literary fairy-tale first arose in Renaissance Venice, originating from oral story-telling traditions that would later become the Arabian Nights, and subsequently in the Parisian salons of Louis XIV. Largely written by, for, and in the name of women, these literary fairy-tales took a lightly comic view of life's vicissitudes, especially female fortune in marriage. Connecting literary representations of bridal goods - dress, jewellery, carriages, toiletries, banqueting and confectionary foods - to the craft histories of their making, this Element offers a newly-contextualised socio-economic account of Renaissance luxe, from architectural interiors to sartorial fashioning and design. By coupling Renaissance luxury wares with their fairy-tale representation, it locates the recherché materialities of bridal goods - gold, silver, diamonds and silk - within expanding colonialist markets of a newly-global early modern economy in the age of discovery.
This Element investigates how the Ghanaian household wealth index is impacted by travel time reduction, which is a direct effect of infrastructural investments from 2000 to 2016. The wealth index is constructed based on the possession of selected assets and reflects the well-being of residents in Ghana. The Element employs two datasets, the Demographic and Health Survey (DHS) and the DHS Covariates. The two-stage least square estimation is implemented to establish the causal relationship. The Element finds that a ten percent reduction in travel time from 2000 to 2015 would result in a 1.2 percent increase in the wealth index from 2003 to 2016. This finding is robust to various settings, including the addition of more control variables, the use of different instrumental variables, and the study of both short-term and long-term effects. The analysis lends support to the Ghanaian government's current economic and infrastructure development plans.
Epidemic Cities provides an overview of the history of epidemics through a particular focus on a range of cities in different regions of the world. The dual focus on both epidemics and specific cities provides an unusual perspective on global history: the analysis of globally circulating epidemics enables reconstructing a variety of wide-reaching entanglements, on the one hand. On the other hand, the concentration with specific urban settings highlights differences and the unevenness engendered by global entanglements. After an introduction concerning the history of the relationship between medicine, epidemics, and cities, the book focuses on the history of three epidemic diseases and how they affected Paris, Buenos Aires, Hong Kong, Bombay, and Baltimore. The timings of major pandemics punctuate the structure of the book: cholera pandemics from the 1830s to the late nineteenth century, bubonic plague at the turn of the twentieth century, and finally tuberculosis until the mid-twentieth century.
Political scientists designing experiments often face the question of how abstract or detailed their experimental stimuli should be. Typically, this question is framed in terms of tradeoffs relating to experimental control and generalizability: the more context introduced into studies, the less control, and the more difficulty generalizing the results. Yet, we have reason to question this tradeoff, and there is relatively little systematic evidence to rely on when calibrating the degree of abstraction in studies. We make two contributions. First, we provide a theoretical framework which identifies and considers the consequences of three dimensions of abstraction in experimental design: situational hypotheticality, actor identity, and contextual detail. Second, we field a range of survey experiments, varying these levels of abstraction. We find that situational hypotheticality does not substantively change experimental results, but increased contextual detail dampens treatment effects and the salience of actor identities moderates results in specific situations.
Mary Wollstonecraft is recognized as an important early feminist. This Element argues that she is also an ingenious moral philosopher, who showed that true virtue and the liberty of women are necessarily interdependent. The Element consists of eight sections. After an introduction, Section 2 discusses Wollstonecraft's concept of reason by examining its metaphysical foundation and its role as moral capacity. According to Wollstonecraft, reason interacts closely with the passions. Then, Sections 3 and 4 discuss the roles of the passions and the imagination. Reason, passion and imagination all come together in Wollstonecraft's discussions of love and friendship, which are the topic of Section 5. Wollstonecraft values education and knowledge, but discussions of her epistemology have been rare. Section 6 analyses some aspects of her views on knowledge. Finally, Section 7 discusses Wollstonecraft's notion of virtue, including its relations to liberty and duty. Section 8 makes some general conclusions.
Evil is sometimes thought to be incomprehensible and abnormal, falling outside of familiar historical and human processes. And yet the twentieth century was replete with instances of cruelty on a massive scale, including systematic torture, murder, and enslavement of ordinary, innocent human beings. These overwhelming atrocities included genocide, totalitarianism, the Holocaust, and the Holodomor. This Element underlines the importance of careful, truthful historical investigation of the complicated realities of dark periods in human history; the importance of understanding these events in terms that give attention to the human experience of the people who were subject to them and those who perpetrated them; the question of whether the idea of 'evil' helps us to confront these periods honestly; and the possibility of improving our civilization's resilience in the face of the impulses towards cruelty to other human beings that have so often emerged.
Slow wonder bears witness to the possibilities of the imagination. In a series of letters the authors playfully imagine alternatives to current orthodoxies that privilege technocratic approaches to education that have strangled discussion about what it might mean to make education good and right, or even beautiful. The authors position the imagination as a powerful site of resistance within education and academic life. They unpack their philosophical positionings through vignettes of their teaching practice, poetry written as reflective musings and discursive theoretical pieces, including letters they have written to others. They attempt to marry the poetic and the academic, the rational and the affective, to model a slow approach to wondering about the joy, beauty and possibilities of life. In this spirit, they contemplate new ways to think and live in education.
This Element is a survey of the field of pathographies of mental illness. It explores classic texts in the field as well as other selected contemporary memoirs. In doing so, the reader is introduced to psychiatric information about various mental illnesses through a narrative lens, emphasizing experience. Because clinical research is evidenced-based and aims to produce generalizable knowledge (i.e., trends), the reading of pathographies can complement these findings with practical experiential insights. By pairing psychiatric information with pathographies, certain personal themes become apparent that are different from the empirical trends identified by scientific and medical researchers. Based on the survey presented here, this Element identifies seven such themes, laying the foundation for future research, inquiry, practice, and policy.
This Element is a guide to task-based language teaching (TBLT), for language instructors, teacher educators, and other interested parties. The work first provides clear definitions and principles related to communication task design. It then explains how tasks can inform all stages of curriculum development. Diverse, localized cases demonstrate the scope of task-based approaches. Recent research illustrates the impact of task design (complexity, mode) and task implementation (preparation, interaction, repetition) on various second language outcomes. The Element also describes particular challenges and opportunities for teachers using tasks. The epilogue considers the potential of TBLT to transform classrooms, institutions, and society.
