This introduction begins with a brief overview of the three major factors shaping economic life and exchange in India, as laid out by contributions in the edited volume Rethinking Markets in Modern India: embedded exchange, contested jurisdiction, and pliable markets. The overarching logic of all the contributions is that markets in India must be understood as path dependent, that is, expressing a historical trajectory and specific, and changing, political and moral regimes. The remainder of this introduction discusses the origins of the distinction between ‘economy’ and ‘culture’ in the nationalist critiques of empire and how these critiques have led to a widespread moral ambivalence vis-à-vis the commercialization of everyday life in India that persists today across the political spectrum.

Far from being a monolithic approach to psychotherapy, cognitive behavioural therapy (CBT) is in fact an umbrella term to describe a family of psychological therapies that share many common features but also have nuanced differences. Of the CBTs, two are often conflated under the ‘CBT’ moniker, namely cognitive therapy (CT) and rational emotive behaviour therapy (REBT). In this article, we explore some of the key differences and similarities between CT and REBT, touching on philosophy, practical implementation, and literature. We provide a brief hypothetical case study to demonstrate the different ways a therapist using CT and REBT might tackle the same client problem. We do not declare either approach superior, but suggest each might have their advantages in certain contexts and acknowledge that skilful practitioners could, and often do, integrate both approaches. As CBT continues to evolve and move into new areas, it is important that psychology practitioners and researchers are clear about which specific approach to CBT they are delivering, measuring and/or reporting on.

I began working on this article in the winter of 2022, when Russia's invasion of Ukraine shattered the fragile stability of Europe. Artur Solomonov's tragifarce How We Buried Josef Stalin (2019) speaks directly to this catastrophic time but also to the legacy of Stalinism in Russia. ‘A play about flexibility and immortality’, Solomonov's farce confronts its audience with the dilemma of Stalinism, which Putin's putrid regime continues to mobilize. Using irony, hyperbole and grotesque, it proposes a dramaturgical response to the question of why hostility to the world, isolationism and nationalistic aspirations are deeply ingrained in the collective psyche of Russian society. To Solomonov, the issue rests in the malleability of a Russian psyche that embraces an image of the tyrant and allows it to remain immortal; it also feeds Russian collective nostalgia, which prepared the ground for the rise of what Lev Gudkov called ‘recurring totalitarianism’.

Is it possible for audiences to be transported to the theatrical past? Though the landmark theatres Teatro Olimpico and Drottningholm Slottsteater appear to differ completely, the meanings of their pasts are interpreted through the concepts of historicity versus historicism. After briefly examining the theatres’ histories and the historiography of their place in theatre history, we then analyse the details of the Olimpico's and Slottsteater's ‘performances’ in the following characteristics: how their distinctive features employ motion and space, the presence of their silent ghost audiences, their similarities as one-room theatres and in the ‘democratic nature’ of their auditoriums, and their use of trompe l'oeil in their construction. Through these elements, the Teatro Olimpico and Drottningholm Slottsteater perform their pasts, achieving their status as iconic playhouses that still make an impact on audiences and visitors. Does that impact effectively ‘take us back in time’?

In the early era of aviation, Frederick Lanchester was both an inventor and a theoretician driven by the need for a theory of flight that would reduce the guesswork in designing new aircraft. His book Aerodynamics in 1907 laid down the early foundations of such a theory. The theory with contributions from others, notably Ludwig Prandtl, was refined to become the basis for the sleek designs of WWII aircraft brought about with little guesswork. New technology changed aircraft design radically with the increased speed of jet propulsion reaching into the transonic range with nonlinear aerodynamics. In the late 1940s and early 1950s substantial guesswork returned to aircraft design. The legacy of Lanchester et al., however, lived on with the development of computational fluid dynamics (CFD) that could guide designers through nonlinear transonic effects. This article presents a historical sketch of how CFD developed, illustrated with examples explaining some of the difficulties overcome in the design of the first-generation swept-wing transonic fighters. The historical study is forensic CFD in search for the likely explanation of the designer’s choice for the wing shape that went into production a long time ago. The capability of current CFD applied to the aerodynamics of aircraft with slender wings is surveyed. The cases discussed involve flow patterns with coherent vortices over hybrid wings and wings of moderate sweep. Vortex-flow aerodynamics pertains to understanding the interaction of concentrated vortices with aircraft components. Modern Reynolds-Averaged Navier-Stokes (RANS) technology is useful to predict attached flow. But vortex interaction with other vortices and breakdown lead to unsteady, largely separated flow which has been found out of scope for RANS. Direct simulation of the Navier-Stokes equations is out of computational reach in the foreseeable future, and the need for better physical modeling is evident. Both cruise performance and stalling characteristics are influenced by strong interactions. Two important aspects of wing-flow physics are discussed: separation from a smooth surface that creates a vortex, and vortex bursting, the abrupt breakdown of a vortex with a subsequent loss of lift. Vortex aerodynamics of not-so-slender wings encounter particularly challenging problems, and it is shown how the design of early-generation operational aircraft surmounted these difficulties. Through use of forensic CFD, the article concludes with two case studies of aerodynamic design: how the Saab J29A wing maintains control authority near stall, and how the Saab J32 mitigates pitch-up instability at high incidence.

We introduce the notion of refined unramified cohomology of algebraic schemes and prove comparison theorems that identify some of these groups with cycle groups. This generalizes to cycles of arbitrary codimension previous results of Bloch–Ogus, Colliot-Thélène–Voisin, Kahn, Voisin, and Ma. We combine our approach with the Bloch–Kato conjecture, proven by Voevodsky, to show that on a smooth complex projective variety, any homologically trivial torsion cycle with trivial Abel–Jacobi invariant has coniveau $1$. This establishes a torsion version of a conjecture of Jannsen originally formulated $\otimes \mathbb {Q}$. We further show that the group of homologically trivial torsion cycles modulo algebraic equivalence has a finite filtration (by coniveau) such that the graded quotients are determined by higher Abel–Jacobi invariants that we construct. This may be seen as a variant for torsion cycles modulo algebraic equivalence of a conjecture of Green. We also prove $\ell$-adic analogues of these results over any field $k$ which contains all $\ell$-power roots of unity.

This review article on Rethinking Markets in Modern India1 uses the notion of the fetish as an entry point to consider the rich and innovative arguments put forward in this volume. It also interrogates ‘the market’ as a conceptual grounding for understanding India’s political economy in the past and present.

In this Modern Asian Studies book symposium, scholars of South Asia analyse the political, ethical, and epistemic aspects of market life, building on the volume Rethinking Markets in Modern India.1 This interdisciplinary conversation approaches transactional realms from the disciplines of history, anthropology, development studies, and political economy. The symposium’s contributors examine a range of pertinent issues that encompass customary forms of exchange and capitalist aspects of trade. Among the topics discussed are those of market fetishism, bazaar knowledge, social embeddedness, forms of transactional representation and translation, and institutional and regulatory contexts for commerce.
