Folk performances reflect the life-worlds of a vast section of subaltern communities in India. What is the philosophy that drives these performances, the vision that enables as well as enslaves these communities to present what they feel, think, imagine, and want to see? Can such performances challenge social hierarchies and ensure justice in a caste-ridden society? In Cultural Labour, the author studies bhuiyan puja (land worship), bidesia (theatre of migrant labourers), Reshma-Chuharmal (Dalit ballads), dugola (singing duels) from Bihar, and the songs and performances of Gaddar, who was associated with Jana Natya Mandali, Telangana: he examines various ways in which meanings and behaviour are engendered in communities through rituals, theatre, and enactments. Focusing on various motifs of landscape, materiality, and performance, the author looks at the relationship between culture and labour in its immediate contexts. Based on an extensive ethnography and the author’s own life experience as a member of such a community, the book offers a new conceptual framework to understand the politics and aesthetics of folk performance in the light of contemporary theories of theatre and performance studies.

George L. Mosse took a ‘cultural turn’ in the latter part of his career, but still early enough to make a pioneering contribution to the study of political culture and in particular what he called political ‘liturgy’, including marches, processions, and practices of commemoration. He adapted to the study of nationalism in the nineteenth and twentieth centuries the approach to the history of ritual developed by historians of medieval and early modern Europe, among them his friend Ernst Kantorowicz. More recently, the concept of ritual, whether religious or secular, has been criticized by some cultural historians on the grounds that it implies a fixed ‘script’ in situations that were actually marked by fluidity and improvisation. In this respect cultural historians have been part of a wider trend that includes sociologists and anthropologists as well as theatre scholars and has been institutionalized as Performance Studies. Some recent studies of contemporary nationalism in Tanzania, Venezuela and elsewhere have adopted this perspective, emphasizing that the same performance may have different meanings for different sections of the audience. It is only to be regretted that Mosse did not live long enough to respond to these studies and that their authors seem unaware of his work.

Considering the further exploration of the ocean, the requirements for deep-sea operation equipment have increased. Many problems existing in the widely used deep-sea hydraulic system have become increasingly prominent. Compared with the traditional deep-sea hydraulic system, actuators using a paraffin phase change material (PCM) have incomparable advantages, including lightweight structure, low energy consumption, high adaptability to the deep sea, and good biocompatibility. Thus, a deep-sea drive microunit (DDM) based on paraffin PCM is proposed in this paper. The device adopts a flexible shell, adapting to the high-pressure environment of the deep-sea based on the principle of pressure compensation. The device realizes the output of displacement and force through the electrothermal drive, which can be used as actuator or power source of other underwater operation equipment. The microunit successfully completes the functional verification experiments in air, shallow water, and hydrostatic pressure of 110 MPa. In accordance with experimental results, a reasonable control curve is fitted, highlighting its potential application in deep-sea micro electro mechanical systems, especially in underwater soft robot.

In the closing scene of René-Charles Guilbert de Pixérécourt's melodramaLa Tête de mort; ou, Les Ruines de Pompeïa(1827), audiences at Paris's Théâtre de la Gaîté were presented with the spectacular cataclysm of an erupting Mount Vesuvius that invaded the city and engulfed the hapless characters in its fiery embrace. “The theatre,” Pixérécourt writes, “is completely inundated by this sea of bitumen and lava. A shower of blazing and transparent stones and red ash falls on all sides…. The red color with which everything is struck, the terrible noise of the volcano, the screaming, the agitation and despair of the characters … all combine to form this terrible convulsion of nature, a horrible picture, and altogether worthy of being compared to Hell.” A few years later, in 1830, Daniel Auber's grand operaLa Muette de Portici(1828), which yoked a seventeenth-century eruption of Vesuvius with a popular revolt against Spanish rule in Naples, opened at the Théâtre de Monnaie in Brussels. The Belgian spectators, inspired by the opera's revolutionary sentiments, poured out into the streets and seized their country's independence from the Dutch. These two famous examples, which form part of a long genealogy of representing volcanic eruptions through various artistic means, highlight not only the compelling, immersive spectacle of nature in extremis but also the ability of stage scenery to intervene materially in the narrative action and assimilate affective and political meanings. As these two examples also indicate, however, the body of scholarship in literary studies, art history, and theatre and performance studies that attends to the mechanical strategies and symbolic purchase of volcanic representations has tended to focus mainly on Europe; more research remains to be undertaken into how volcanic spectacles have engaged with non-European topographies and sociopolitical dynamics and how this wider view might illuminate our understanding of theatre's social roles.

Starting from the finding of the performative drift that marked the theatrical research through the Seventies and Eighties, this essay aims to show how two of the main protagonists of the period – Theatre Anthropology and Performance Studies – have contributed in their affinities and specificities to marginalizing of the theatre as a cultural phenomenon and devaluating of the artistic work, inaugurated (and not yet rectified) by Postmodernity.

This article examines the early representations of Prince Albert that either satirize or attempt to reconcile the hierarchical ambiguities and issue of threatened masculinity that resulted from unconventional male consortship and female rule. It concludes that the latter was achieved through the development of a suitable and legible iconography for a nineteenth-century male consort in adherence with British iconographic tradition and values. Drawing from methods in nineteenth-century art history as well as gender and performance studies and anthropology, it argues that images of the male body play a fundamental role in the construction and perpetuation of masculine ideology and subjectivity through the creation of the semblance of an innate and axiomatic masculine archetype. In doing so, this article problematizes and historicizes masculinity by illuminating the plurality of expressions of masculinity and rejecting the essentialist narrative of masculinity as something measurable or quantifiable, as well as ahistorical, atemporal, apolitical and heteronormative.
