The production technology of Egyptian blue and green frits from second millennium BC Egypt and Mesopotamia

The microstructures and chemical compositions of some 55 Egyptian blue and green frit samples from New Kingdom Egypt and 15th century BC Mesopotamia are determined using analytical scanning electron microscopy, the main focus being on frit cakes, powder residues, and frit vessel and bead fragments from one of the “factory areas” at Amarna in Middle Egypt. Replicate Egyptian blue frits produced in the laboratory are similarly investigated. Comparison of the microstructures of the ancient and replicate samples suggest that frit cakes are the primary product, and that these were ground to produce the powder, and then moulded to shape and refired to produce the vessels and beads. Egyptian blue and green frits are shown to be distinct pigments, the pigment produced depending on the relative proportions of copper oxide and lime in the mixtures. The bulk and glass phase compositions are used to try to infer the different sources of the quartz, lime, copper and alkali flux used in the production of frits from Egypt and Mesopotamia. An estimate is made of the scale of production of Egyptian blue frit in New Kingdom Egypt.     

Issue competition between Green and social democratic parties in majoritarian settings: the case of Australia

The emergence of green parties has injected new lines of competition into national party systems, with discernible issue competition effects for established, ideologically-proximate social democratic parties. Despite a burgeoning literature on green and social democratic issue competition tactics in settings where coalition government is common, we have less understanding of these same effects in settings where majority government is the norm. Using the case of the Australian Greens and the Australian Labor Party, we explore issue competition dynamics in a polity where the majoritarian electoral system reduces opportunities for coalition formation. We find that the absence of strong electoral imperatives for either party to enter coalitions has encouraged them to compete adjacent to one another, rather than in direct competition.     

T.H. Green, advanced liberalism and the reform question 1865–1876

This paper examines Thomas Hill Green's changing attitude to the Reform Question between 1865 and 1876. Section 1 sketches the Radical landscape against which Green advocated reform between 1866 and 1867, paying particular attention to the respective positions of Gladstone, J.S. Mill and Bright on the relationship between responsible citizenship and class membership. Section 2 examines Green's theories of social balance and responsible citizenship at the time of his lectures on the English Civil War. Section 3 argues that, contrary to the established scholarship, Green's Radicalism was closer to Bright than to Gladstone and Mill during this period. Section 4 counters Richter's claim that Green abandoned democracy following the 1874 General Election, while arguing that even sympathetic commentators misunderstand Green's attitude to the Reform Question immediately after this date.     

Obituary. Wolfgang Scharfe (1942–2003)

At the turn of the twentieth century, a popular mania developed around the idea that Mars was inhabited by intelligent beings. This obsession was originally based in the science of the time, but it outlasted astronomers' certainty regarding the red planet's conditions of habitability. Cartography was vital to the popular construction of Mars as an inhabited world and created a powerful landscape icon that differed significantly from the observations of astronomers. Acceptance of a Martian civilization began to wane only when cartography's status as an objective representational format was weakened by new photographic technology in the early 1900s. Although the processes and formats of cartography are rarely considered primary factors in the Mars mania, they were integral to the origin, development and expiration of the conceptualization of Mars as a world that was possibly inhabited.     

‘Her – she,this woman,me’: the representation of subjectivity in Tom Murphy's Alice Trilogy

In this essay, I will discuss Murphy's exploration of the (un)bearable nature of an existence characterised by loss, and by longing, in his recent play sequence Alice Trilogy (2005). Positing the explicitly dualised characterisation in the first and third of these plays as a reflection of, and natural progression from, earlier dramaturgic representations of duality, I will examine Murphy's overt rendering of subjectivity, in Alice Trilogy, focusing upon the ways in which such theatrical duality explicates the silences which pervade the Purgatorial affective no-man's-land – or ‘in-betweenness’ – of mind, body, and soul.     

‘The Stupidest Tea-Party in All My Life’: Lewis Carroll and Victorian Psychiatric Practice

An analysis of the numerous connections of Lewis Carroll to the Victorian psychiatric profession reveals their influence on the portrayal of insanity in Carroll’s fiction. Through examining his relationship with his uncle Robert Wilfred Skeffington Lutwidge, a Commissioner in Lunacy, and collating Carroll’s personal recollections from diaries and letters with correspondences of the Lunacy Commission, this article offers a comprehensive picture of Carroll’s intellectual engagement with Victorian psychiatry. Combining these insights with his literary writings illuminates the psychiatric origins of the ‘Mad Tea-Party’ and characters such as the Hatter in Alice’s Adventures in Wonderland in the organization and methods of mid-Victorian pauper lunatic asylums and their treatment of impoverished workers. Likewise, the illustrations of Carroll’s works stood in dialogue with popular imagery of insanity as well as ideas of physiognomy and their diagnostic application in asylum photography by Hugh Welch Diamond. This piece will argue that the framework of Victorian psychiatry provided Carroll with imagery he utilizes to satirize aspects of Victorian moral values. It thus aims to highlight the benefits of re-framing the works of Lewis Carroll beyond the genre children’s literature, and considering them as part of the wider Victorian discourse of the sciences of the mind.     

‘There's only so much money hot dog sales can bring in’: The intersection of green school grounds and socio-economic status

In the interest of enhancing children's environments, many school grounds around the world are being ‘greened’ as asphalt and manicured grass are replaced with a diversity of elements and spaces, such as trees, shrubs, gardens, art, and gathering areas. Despite a growing body of research from a number of disciplines that is exploring the potential of these spaces, very little is known about how issues of socio-economic status (SES) influence school ground greening initiatives. In this paper, I explore what (if any) relationship exists between school ground greening and SES in a Canadian school board where approximately 20% of more than 500 schools have begun the greening process. A mixed methods approach was used: (1) 149 questionnaires were completed by administrators, teachers, and parents associated with 45 school ground greening initiatives; and (2) 21 follow-up interviews were conducted with administrators, teachers and parents at five greening projects across a range of SESs. Three significant, and arguably troubling, patterns emerged as a function of socio-economic status of the school community. Participants associated with schools across a range of SESs had different: (1) perceptions as to the importance/adequacy of green school grounds; (2) access to adult support; and (3) access to funding. The implications of these findings are discussed.     

PSHA for Broad-Band Strong Ground-Motion Hazards in the Saronikos Gulf,Greece, from Potential Earthquake with Synthetic Ground Motions

We perform a probabilistic seismic hazard analysis (PSHA) for broad-band strong ground motion within the Saronikos Gulf region, Greece, from potential earthquakes along the 30 km long Aigina fault in the northern part of the Gulf. We perform the PSHA utilizing empirical Green’s functions (EGFs) merged with synthetic Green’s functions (SGFs) along with models of finite rupture in place of standard “attenuation relations.” Our approach considers all significant magnitudes for PSHA and full broadband ground motion simulations. Calculations are source and site specific, and could reduce uncertainties in estimating standard engineering parameters. We use a range of rupture scenarios for all significant magnitude earthquakes along the fault. The hazard calculation is for frequencies 0.0– 15.0 Hz. Recordings of small earthquakes from an onshore/offshore local seismic array were used as EGFs for frequencies of 1.5–15.0 Hz, the finite difference code E3D was utilized to synthesize SGFs for frequencies 0.0–1.5 Hz, and an algorithm for merging the EGFs with SGFs was developed. The full-waveform calculations are important for non-linear dynamic analysis of structures in the coastal zone and potential hazard to long period structures. Results of proposed PSHA identify 2%, 10%, and 50% hazard at the selected sites of Saronikos Gulf.

Finally, we compare our PSHA results to those obtained by standard practice which involves prediction equations (GMPEs) recently developed in the Next Generation Attenuation (NGA) project and empirical predictive attenuation relations proposed for Greece. We believe that differences with the NGA results are due to site- and source-specific information utilized in this study, and incorporation of this information may significantly reduce the uncertainty in seismic hazard calculations.
