The charophyte Lamprothamnium succinctum as an environmental indicator: a Holocene example from Tom Thumbs Lagoon,eastern Australia

The palaeobiota from a middle to late Holocene succession in Tom Thumbs Lagoon, N.S.W., Australia, reflects a range of environmental conditions caused by sea-level changes and active estuarine sedimentation. At the base of the succession (～ ?0.4 m AHD) a thin bed, containing molluscs dated at 6.7 ka B.P. by radiocarbon and amino acid racemisation, and foraminifers is indicative of open estuarine conditions. From +0.35 m AHD towards the top of the sequence the charophyte Lamprothamnium succinctum occurs in subrecent deposits. This species is characterised here by statistical measurements, and new characters are described and illustrated. The charophytes record a drop in sea level and the establishment of a lower salinity artificial wetland. The investigation has also established that decalcification in charophytes can be related to acidification produced by the release of organic acids, aggravated after 1928 by anthropogenic pollution.     

Shelley’s “Letter to Maria Gisborne” as Workshop Poetry

ABSTRACT

Shelley’s “Letter to Maria Gisborne” is a playful improvisational verse epistle, widely praised for its urbanity and its display of the poet’s invention. The verses turn on a catalogue of the collection of odd scientific and mechanical objects that Shelley found scattered around him in the place he composed the letter, the Livorno workshop of Gisborne’s son, a young engineer who was building a new-model steamboat at the time (with Shelley’s financial and intellectual backing). In the context of that space, the poem reads as a response to competing notions of invention. For Shelley, the engineer’s workshop is an attractive alternative to the poet’s tower—which was uncomfortably close to a Grub Street garret. Verbal and visual images of poets’ and scientists’ workshops, from Hogarth and Mary Robinson, to Joseph Wright of Derby and Frankenstein, illustrate the tensions embodied in the physical location and poetic performance of Shelley’s celebrated “Letter.”     

The roots of the global economic crisis (Respond to this article at http://www.therai.org.uk/at/debate)

The world economic crisis should be seen as an episode in the history of money. “National capitalism” was the main way of organizing money in the twentieth century and its symbol was national monopoly currency. This system has been unravelling since the US dollar de‐pegged from gold in 1971. The result is a disconnect between politics which are still largely national and the money circuit which is decentralized and global. The work of Georg Simmel and Karl Polanyi is enrolled to explain this development which entails the loss of money's physical substance, a shift in the social institutions supporting it and a break‐up of the forms and functions of “all‐purpose money”. The euro crisis reveals the historical mistake of treating market economy as a driver of society and politics. Good intentions at this stage will not reverse what has become a Greek tragedy in more senses than one.     

Heritage designation and scale: a World Heritage case study of the Ningaloo Coast

As heritage research has engaged with a greater plurality of heritage practices, scale has emerged as an important concept in Heritage Studies, albeit relatively narrowly defined as hierarchical levels (household, local, national, etcetera). This paper argues for a definition of scale in heritage research that incorporates size (geographical scale), level (vertical scale) and relation (an understanding that scale is constituted through dynamic relationships in specific contexts). The paper utilises this definition of scale to analyse heritage designation first through consideration of changing World Heritage processes, and then through a case study of the world heritage designation of the Ningaloo Coast region in Western Australia. Three key findings are: both scale and heritage gain appeal because they are abstractions, and gain definition through the spatial politics of interrelationships within specific situations; the spatial politics of heritage designation comes into focus through attention to those configurations of size, level and relation that are invoked and enabled in heritage processes; and researchers choice to analyse or ignore particular scales and scalar politics are political decisions. Utilising scale as size, level and relation enables analyses that move beyond heritage to the spatial politics through which all heritage is constituted.
