Charles Johnstone's literary output - which included Chrysal: or, the Adventures of a Guinea (1760) and a series of novels between 1762 and 1781 prior to his departure for Calcutta in 1782 - features a marked geographical and historical preoccupation with empire. The trajectory of Johnstone's life from Carrigogunnell and Dublin in Ireland, to London, and finally to Calcutta, indicates the remarkable possibilities for self-transformation which empire from Ireland to India offered during the eighteenth century. This paper examines the significance of empire in Johnstone's oeuvre, and identifies for the first time a series of articles written by him in The Calcutta Gazette in 1785.

Suppose X is a projective toric scheme defined over a ring R and equipped with an ample line bundle L . We prove that its K-theory has a direct summand of the form K(R)(k+1) where k = 0 is minimal such that L?(-k-1) is not acyclic. Using a combinatorial description of quasi-coherent sheaves we interpret and prove this result for a ring R which is either commutative, or else left noetherian.

The Premio Cervantes, one of the most prestigious prizes awarded for literature in the Spanish language, was established in 1976 as Spain negotiated the Transition to democracy in the post-Franco era. This article examines the context in which the prize was created and subsequently used to negotiate inter-continental relations between Spain and Latin America. The article highlights the exchanges of economic, political and symbolic capital which took place between the Spanish State, its representative, the King of Spain, and winning Latin American authors. Significantly, the involvement of the Spanish State is shown to bring political capital into play in a way that commercial prizes do not. In so doing, the Premio Cervantes gives those formerly at the colonial periphery the opportunity to speak out and negotiate the terms of a new kind of relationship with the former colonial center.

An investigation of the long controversy around the definition of an Italian New Wave cinema of the 1960s, this essay engages (and takes issue) with the reasons behind the critics’ reluctance to recognise its existence. After establishing a theoretical and historical framework for a transnational under- standing of the phenomenon of the European and World New Waves, it offers a reasoned analysis of the multiple industrial and artistic attempts at a generational renewal of Italian cinema that were made in Italy during the 1960s. Ultimately, the essay suggests that it would not only be appropriate, but also highly productive to reconsider the vibrant and heterogeneous young Italian cinema of the 1960s under the generational and transnational New Wave label, instead of continuing to approach the decade exclusively in the light of Neorealism.

This article seeks to provoke a deeper engagement of Critical Security Studies with security's relations to technology and weapons. It explores existing assumptions about these relations in mainstream arms control and disarmament theory, and the way such assumptions are deployed and distributed in the current settlement of arms control and disarmament practice. It then draws on recent social and philosophical discussions of materiality, particularly on the thought of Bruno Latour, to propose a different set of concepts for exploring the aims and limits of arms control and disarmament. These concepts emphasise the mediating roles of material things in social relations and they may offer a richer view of the object of arms control (weapons and violence) and of the practices of arms limitation and reduction; one that may ultimately gesture towards a different understanding of arms politics, and that may be used to explore the transformatory potentials of arms control and disarmament.

The phase behavior of a model system of colloidal platelets and nonadsorbing polymers is studied using computer simulations and perturbation theory. The equation of state for the pure platelet reference system is obtained by Monte Carlo simulations, and the free volume fraction accessible to polymers is measured by a trial insertion method. The free volume fraction is also calculated using scaled particle theory. Subsequently, the phase diagram for platelet-polymer mixtures is calculated. For a platelet aspect ratio L/D=0.1 and a polymer to platelet size ratio d/D>0.2, we observe coexistence between two isotropic phases with different densities. For smaller polymers d/D

In the literature, politeness has been researched within many disciplines. Although Brown and Levinson’s theory of politeness (1978, 1987) is often cited, it is primarily a linguistic theory and has been criticized for its lack of generalizability to all cultures. Consequently, there is a need for a more comprehensive approach to understand and explain politeness. We suggest applying a social signal framework that considers politeness as a communicative state. By doing so, we aim to unify and explain politeness and its corresponding research and identify further research needed in this area.

This article addresses the relative absence of class-based analysis in theatre and performance studies, and suggests the reconfiguration of class as performance rather than as it is traditionally conceived as an identity predicated solely on economic stratification. It engages with the occlusion of class by the ascendancy of identity politics based on race, gender and sexuality and its attendant theoretical counterparts in deconstruction and post-structuralism, which became axiomatic as they displaced earlier methodologies to become hegemonic in the arts and humanities. The article proceeds to an assessment of the development of sociological approaches to theatre, particularly the legacy of Raymond Williams and Pierre Bourdieu. The argument concludes with the application of an approach which reconfigures class as performance to the production of Declan Hughes's play Shiver of 2003, which dramatizes the consequences of the dot.com bubble of the late 1990s for ambitious members of the Irish middle class.

This article concerns the legal issues that surround the prohibition of doping in sport. The current policy on the use of performance enhancing drugs (PEDs) in sport is underpinned by both a paternalistic desire to protect athletes’ health and the long-term integrity or ‘spirit’ of sport. The policy is put into administrative effect globally by the World Anti-Doping Agency (WADA), which provides the regulatory and legal framework through which the vast majority of international sports federations harmonise their anti-doping programmes. On outlining briefly both the broad administrative structures of international sport’s various anti-doping mechanisms, and specific legal issues that arise in disciplinary hearings involving athletes accused of doping, this article questions the sustainability of the current ‘zero tolerance’ approach, arguing, by way of analogy to the wider societal debate on the criminalisation of drugs, and as informed by Sunstein and Thaler’s theory of libertarian paternalism, that current policy on anti-doping has failed. Moreover, rather than the extant moral and punitive panic regarding doping in sport, this article, drawing respectively on Seddon’s and Simon’s work on the history of drugs and crime control mentality, contends that, as an alternative, harm reductionist measures should be promoted, including consideration of the medically supervised use of certain PEDs.
