Thomas De Quincey’s terrifying oriental nightmares, reported to sensational acclaim in his Confessions of an English Opium-Eater (1821), have become a touchstone of romantic imperialism in recent studies of the literature of the period (Leask 1991; Barrell 1992 et al). De Quincey’s collocation of “all creatures, birds, beasts, reptiles, all trees and plants, usages and appearances, that are found in all tropical regions” in the hypnagogic hallucinations that characterized what he called “the pains of opium” seems to anticipate neatly Said’s theory of orientalism, whereby the orient was supplied by the west with “a mentality, a genealogy, an atmosphere,” the attitudinal basis as he argues for the continuing march of imperialism from the late eighteenth century. Yet, as Thomas Trautmann (1997) has pointed out, orientalist scholarship based in India and led by the influential Asiatic Society of Bengal in the late eighteenth century was extremely enthusiastic about Indian classical antiquity. The early orientalist scholarship posited ethnic, linguistic, cultural and religious links between Europe and India, while recognizing the greater antiquity of Indian civilization. This favourable attitude (which Trautmann calls “Indomania”) was overtaken in the nineteenth century by disavowal of that scholarship and repugnance (which he calls “Indophobia”), influenced by utilitarian and evangelical attitudes to colonialism. De Quincey’s lifespan covers this crucial period of change. My paper examines his evangelical upbringing and interest in biblical and orientalist scholarship to suggest his anxious investment in these modes of thinking. I will suggest that the bizarre orientalist fusions of his dreams can be better understood in the context of changing attitudes to the imperialism during the period. An examination of his work provides a far more dynamic understanding of the processes of orientalism than the binary model suggested by Said. The transformation implied from imperial scholarship to governance, I will suggest, is not irrelevant to a world which continues to pull apart on various grounds of race and ethnicity, and reflects on our own role in the academy today.

A sacrificial templating process using lithographically printed minimal surface structures allows complex de novo geometries of delicate hydrogel materials. The hydrogel scaffolds based on cellulose and chitin nanofibrils show differences in terms of attachment of human mesenchymal stem cells, and allow their differentiation into osteogenic outcomes. The approach here serves as a first example toward designer hydrogel scaffolds viable for biomimetic tissue engineering.

This chapter outlines the working methods of the prolific writer and lyricist Thomas Moore—which were characterized by the unfortunate combination of a perfectionist streak, a tendency to release material to the publishers while still in the creative mode, and a tendency to re-visit previously-published material. The Gibson-Massie Moore collection at Queen's University Belfast teaches us a great deal about Moore’s creative processes, and also records the nineteenth-century publishing industry’s response to one of its most prolific and popular creative artists. This chapter is illustrated by an online Exhibition, the 'Thomas Moore Project', Digital Collections, Special Collections, McClay library (see URL below).

In North America, terrestrial records of biodiversity and climate change that span Marine Oxygen Isotope Stage (MIS) 5 are rare. Where found, they provide insight into how the coupling of the ocean-atmosphere system is manifested in biotic and environmental records and how the biosphere responds to climate change. In 2010-2011, construction at Ziegler Reservoir near Snowmass Village, Colorado (USA) revealed a nearly continuous, lacustrine/wetland sedimentary sequence that preserved evidence of past plant communities between similar to 140 and 55 lea, including all of MIS 5. At an elevation of 2705 m, the Ziegler Reservoir fossil site also contained thousands of well-preserved bones of late Pleistocene megafauna, including mastodons, mammoths, ground sloths, horses, camels, deer, bison, black bear, coyotes, and bighorn sheep. In addition, the site contained more than 26,000 bones from at least 30 species of small animals including salamanders, otters, muskrats, minks, rabbits, beavers, frogs, lizards, snakes, fish, and birds. The combination of macro- and micro-vertebrates, invertebrates, terrestrial and aquatic plant macrofossils, a detailed pollen record, and a robust, directly dated stratigraphic framework shows that high-elevation ecosystems in the Rocky Mountains of Colorado are climatically sensitive and varied dramatically throughout MIS 5

Despite its wide implications for many ecological issues, the global pattern of spatial turnover in the occurrence of species has been little studied, unlike the global pattern of species richness. Here, using a database on the breeding distributions of birds, we present the first global maps of variation in spatial turnover for an entire taxonomic class, a pattern that has to date remained largely a matter of conjecture, based on theoretical expectations and extrapolation of inconsistent patterns from different biogeographic realms. We use these maps to test four predictions from niche theory as to the form that this variation should take, namely that turnover should increase with species richness, towards lower latitudes, and with the steepness of environmental gradients and that variation in turnover is determined principally by rare (restricted) species. Contrary to prediction, we show that turnover is high both in areas of extremely low and high species richness, does not increase strongly towards the tropics, and is related both to average environmental conditions and spatial variation in those conditions. These results are closely associated with a further important and novel finding, namely that global patterns of spatial turnover are driven principally by widespread species rather than the restricted ones. This complements recent demonstrations that spatial patterns of species richness are also driven principally by widespread species, and thus provides an important contribution towards a unified model of how terrestrial biodiversity varies both within and between the Earth's major land masses.

Boolean games are a framework for reasoning about the rational behaviour of agents, whose goals are formalized using propositional formulas. They offer an attractive alternative to normal-form games, because they allow for a more intuitive and more compact encoding. Unfortunately, however, there is currently no general, tailor-made method available to compute the equilibria of Boolean games. In this paper, we introduce a method for finding the pure Nash equilibria based on disjunctive answer set programming. Our method is furthermore capable of finding the core elements and the Pareto optimal equilibria, and can easily be modified to support other forms of optimality, thanks to the declarative nature of disjunctive answer set programming. Experimental results clearly demonstrate the effectiveness of the proposed method.

In Boolean games, agents try to reach a goal formulated as a Boolean formula. These games are attractive because of their compact representations. However, few methods are available to compute the solutions and they are either limited or do not take privacy or communication concerns into account. In this paper we propose the use of an algorithm related to reinforcement learning to address this problem. Our method is decentralized in the sense that agents try to achieve their goals without knowledge of the other agents’ goals. We prove that this is a sound method to compute a Pareto optimal pure Nash equilibrium for an interesting class of Boolean games. Experimental results are used to investigate the performance of the algorithm.

Complementarity has been extolled as the pioneering way for the International Criminal Court (ICC) to navigate the difficulties of state sovereignty when investigating and prosecuting international crimes. Victims have often been held up to justify and legitimise the work of the ICC and states complementing the Court through domestic processes. This article examines how Uganda has developed its laws, legal procedure, and accountability for international crimes over the past decade. This has culminated in the trial of Thomas Kwoyelo, which after five years of proceedings, has yet to move to the trial phase, due to the issue of an amnesty. While there has been a profusion of provisions to allow victims to participate, avail of protection measures and reparations, in practice very little has changed for them. This article highlights the dangers of complementarity being the sole solution to protracted conflicts, in particular the realisation of victims’ rights.

In 1858, a volume entitled Midnight Scenes and Social Photographs – being sketches of life in the streets, wynds and dens of the city of Glasgow was published under the pseudonym of ‘Shadow’ by Alexander Brown, a Glaswegian flâneur and reformer. Its frontispiece is an etching which depicts a theatre-like proscenium arch whose curtains have been withdrawn to reveal to the audience all the poverty, destitution and disorder that one was likely to find after dark in the insalubrious quarters of the city. At the extreme left-hand side, partly obscured by the curtain a silhouetted figure stands behind an unwieldy camera perched on a tripod. Distinctly unaffected by the mêlée, an arm is calmly raised and a finger precisely arched in the moment before the shutter is clicked and the scene committed to record. The volume, however, relies exclusively on textual descriptions to evoke the underside of the city and contains no photographs at all. Instead, the use of the word photograph in the title can be understood as a metaphor for detached scientific objectivity, a quality much celebrated by nineteenth-century reformers and investigators of social ills. As it happened, a decade after Shadow disappeared into the labyrinthine back-lands of Old Town Glasgow, he was followed there by a real photographer. In 1868, Thomas Annan was commissioned by the City Improvements Trust to take photographs of the Old Town in its last moments of existence before it was pulled down under a series of legislative acts. But perhaps paradoxically, given Shadow’s faith in the analytical properties of photography, Annan’s work seems to refute much of the material contained in Midnight Scenes and other similar tracts. Instead of the dens, shebeens, labyrinths and rowdy crowds described by Shadow, Annan’s depictions of the Old Town convey a static, calm environment, one which is often sparsely inhabited by a curious but apparently orderly population.

Taking account of the sensational tendencies of many reformists’ texts, this paper investigates the discrepancies between the two representations, focussing in particular on the constraints which operated on Annan during his commission. It argues that Annan’s compositions – which became very influential on other 19th century photographers of everyday life such as John Thomson or Jacob Riis – far from being dispassionate analytical works, emerged as a result of a matrix of factors which included: photographic and artistic precedents; Annan’s own predilections as a photographer; technological limitations; the nature of the commission from the City Improvements Trust and political climate in which it was given; the medieval urban fabric in which he had to operate; and, perhaps, most importantly, the identity of the Old Towns inhabitants themselves.

Chiapas representó en el siglo XVII una región donde confluían los mitos, temores y fascinaciones de colonos y europeos. Al ser visitada por Thomas Gage en su travesía hacia Guatemala, es descrita en su Nuevo reconocimiento de las Indias Occidentales de modo muy distinto cuando el narrador, como es este caso, registra sus vivencias personales e, incluso, pasionales. Sólo la historiografía moderna podría explicarnos particulares pasajes en que el viajero es abordado súbitamente por una realidad que pasa desapercibida a otros viajeros con un programa muy claro de supervisión y registro de datos, como es el caso de Antonio Vázquez de Espinosa en su Descripción de la Nueva España. Si el historiógrafo describe puntualmente flora, fauna y geografía, el narrador huele, paladea y recorre con nosotros el laberinto de la tierra chiapaneca. El paisaje a través de la persona, con todos los cabos sueltos y apariciones inexplicables para quien se interna en lo desconocido, cobran, a la luz de investigaciones recientes acerca del contexto sociohistórico de Chiapas, un sentido cabal que no sólo nos ilustra, sino que nos interna y se nos interna.
