Gallirallus temptatus Kirchman & Steadman, 2006, new species
No full text† <i>Gallirallus temptatus</i> new species <p> <b>Holotype.</b> Complete coracoid UF 63302 (Figure 2 B) from the Route 100 archaeological site, Rota, Commonwealth of the Northern Mariana Islands.</p> <p> <b>Paratypes.</b> From the Route 100 site: Rostrum missing both lateral rami UF 63296. Frontal­interorbital portion of cranium UF 63293. Complete vertebrae UF 63301, 63305. Coracoid missing sternal end UF 63292. Scapula missing posterior half UF 63300. Proximal ulna UF 63304. Proximal carpometacarpus UF 63299 (Figure 2 B). Distal tibiotarsus UF 63319. Tarsometatarsus lacking distal trochleae UF 63303. From the Mochong site: Distal femur UF 62964. Proximal tibiotarsus UF 62965. Complete tarsometatarsus UF 62962. Distal tarsometatarsus UF 62963.</p> <p> <b>Diagnosis.</b> A medium­sized rail, slightly smaller overall than <i>Gallirallus philippensis</i> (Table 3), with the following unique combination of characters (summarized in Table 4). Coracoid: facies articularis sternalis narrow, shallow; foramen nutrium supracoracoidei large; lateral margin of facies articularis humeralis short and rounded in humeral aspect. Scapula: in proximal aspect, area between facies articularis humeralis and facies articularis clavicularis shallow. Ulna: intermediate (compared to <i>G. owstoni</i> and <i>G. philippensis</i>) in size relative to leg elements, with deep, well­emarginated depressio musculo brachialis. Carpometacarpus: length from processus pisiformis to proximal end of spatium intermetacarpalis short.</p> <p> <b>Etymology.</b> From the Latin <i>tento</i> (<i>tempto</i>), which means “try, prove, put to the test” (Brown 1956:819). The name <i>temptatus,</i> a masculine adjective, refers to how trying it has been for rails of the genus <i>Gallirallus</i> to survive on Rota. † <i>Gallirallus temptatus</i> became extinct in prehistoric times, whereas biologists have attempted to establish a wild population of <i>G. owstoni</i> on Rota since 1990, with little success in spite of valiant effort.</p> <p> <b>Remarks.</b> Many of the characters used to diagnose † <i>Gallirallus temptatus</i> are associated with reduction of the flight apparatus relative to overall body size. The leg bones of † <i>G. temptatus</i> are not distinguishable from those of <i>G. philippensis</i>.</p>Published as part of <i>Kirchman, Jeremy J. & Steadman, David W., 2006, Rails (Rallidae: Gallirallus) from prehistoric archaeological sites in Western Oceania, pp. 1-31 in Zootaxa 1316</i> on pages 8-10, DOI: <a href="http://zenodo.org/record/173941">10.5281/zenodo.173941</a>

Canaletto's Camera
No full textCanaletto's Camera explores the ways in which the great Venetian artist Antonio Canaletto (1697-1768) made use of the camera obscura - the forerunner of the photographic camera - as an aid to drawing and painting. It surveys Canaletto's contacts with contemporary Venetian and Paduan scientists, in particular Francesco Algarotti who wrote on Newton's philosophy and the camera obscura. Canaletto also relied on many measured drawings of Venetian buildings by his colleague Antonio Visentini, a debt that has not previously been recognised.
Steadman proposes that Canaletto used the camera for two purposes: tracing from real scenes, and copying and collaging drawings and engravings by other artists. By analysing camera sketches made by Canaletto in a notebook, he shows how the artist traced views in Venice and then altered the real scenes in his finished drawings and paintings. By using a reconstructed eighteenth-century design of camera obscura, the author and his colleagues have made drawings of views that Canaletto painted in London. Steadman has recreated both a veduta (a real view) and a capriccio (a fantasy) using Canaletto's processes of 'photomontage'. The experiments are detailed in the book, shedding new light on the artist's procedures, and emphasising how weak and permeable the boundary is between the two types of picture.
Praise for Canaletto's Camera
'In this enthralling book, Philip Steadman effortlessly bridges art and science. He depicts Canaletto’s Venice not as the city of Casanova and carnival but as a hub of Enlightenment knowledge, exploring the artist’s use of the latest optical instruments through practical experiment and penetrating visual analysis. The results are fascinating and totally convincing.'
Deborah Howard, Cambridge University and author of The Architectural History of Venice
'It has always been known that Canaletto used camera obscuras. More than one of his contemporaries wrote as much. What has never been clear is exactly how he did so – until now. This is a fascinating, groundbreaking book which reveals absolutely fresh vistas on the art of the past'
Martin Gayford, art critic at The Spectator and author of Venice: City of Picture

Benchmarking the energy performance of the UK non-domestic stock: a schools case study
No full textLack of awareness of building performance is often highlighted as a key barrier to improving the operational energy efficiency of non-domestic buildings. In 2008, the Display Energy Certificate (DEC) scheme was implemented in the UK to raise awareness and encourage higher levels of energy efficiency in public sector buildings. The thesis reports a review of the energy benchmarks that underpin the DEC scheme, which reveals that they are no longer appropriate for providing useful or relevant feedback. The research therefore aims to improve understanding of the energy performance of non-domestic buildings, and to explore ways in which their operational energy efficiency can be benchmarked with greater robustness. The research comprises four phases of analysis within which data of varying granularity are analysed to acquire a holistic understanding of the patterns of energy use in English schools and the factors that influence their energy demand. First, the latest DEC records are analysed to assess the robustness of the scheme. Second, the patterns of energy use in primary and secondary schools are analysed in greater detail. Third, multiple regression analyses of energy use in relation to intrinsic building and occupant characteristics are carried out. Last, detailed information about the end-use energy consumption of a small number of modern secondary schools is analysed. The main findings reveal shortcomings of the DEC scheme. The results highlight two key issues associated with the classification system: inappropriate levels of aggregation and misclassification of buildings. Energy benchmarks are found to be inappropriate and out-of-date for the majority of benchmark categories. Correlations between intrinsic features and empirical data on the energy performance of schools were found. The research concludes that the DEC scheme lacks robustness, and that its robustness could be improved by refining the classification system based on empirical data, introducing a framework for keeping up-to-date with the latest trends in energy performance, and producing benchmarks that are relevant to the circumstances of individual buildings
