Reports from the Fifth EAHN Meeting in Tallinn

The fifth international meeting of the European Architectural History Network was held in Tallinn, at the National Library of Estonia, from 13 to 16 June 2018. The reports from this meeting aim to capture some of the main themes that came up during four intense days of academic discussions and exchange, meetings, and free-form interaction in different spatial and social settings. After the introduction by Andres Kurg, host of the Tallinn Meeting, five delegates review the five thematic tracks which organised the selected sessions and ran in parallel throughout the three days of the conference: Mediations, Comparative Modernities, Peripheries, Discovery and Persistence, and Body and Mind. In his closing keynote lecture, Reinhold Martin from Columbia University further reflected on the ample critical discussions which had taken place throughout the conference

A randomised controlled trial investigating the effect of nutritional supplementation on visual function in normal, and age-related macular disease affected eyes: design and methodology [ISRCTN78467674]

BACKGROUND: Age-related macular disease is the leading cause of blind registration in the developed world. One aetiological hypothesis involves oxidation, and the intrinsic vulnerability of the retina to damage via this process. This has prompted interest in the role of antioxidants, particularly the carotenoids lutein and zeaxanthin, in the prevention and treatment of this eye disease. METHODS: The aim of this randomised controlled trial is to determine the effect of a nutritional supplement containing lutein, vitamins A, C and E, zinc, and copper on measures of visual function in people with and without age-related macular disease. Outcome measures are distance and near visual acuity, contrast sensitivity, colour vision, macular visual field, glare recovery, and fundus photography. Randomisation is achieved via a random number generator, and masking achieved by third party coding of the active and placebo containers. Data collection will take place at nine and 18 months, and statistical analysis will employ Student's t test. DISCUSSION: A paucity of treatment modalities for age-related macular disease has prompted research into the development of prevention strategies. A positive effect on normals may be indicative of a role of nutritional supplementation in preventing or delaying onset of the condition. An observed benefit in the age-related macular disease group may indicate a potential role of supplementation in prevention of progression, or even a degree reversal of the visual effects caused by this condition

Experimental evidence for sustained carbon sequestration in fire-managed, peat moorlands.

Peat moorlands are important habitats in the boreal region, where they store approximately 30% of the global soil carbon (C). Prescribed burning on peat is a very contentious management strategy, widely linked with loss of carbon. Here, we quantify the effects of prescribed burning for lightly managed boreal moorlands and show that the impacts on peat and C accumulation rates are not as bad as is widely thought. We used stratigraphical techniques within a unique replicated ecological experiment with known burn frequencies to quantify peat and C accumulation rates (0, 1, 3 and 6 managed burns since around 1923). Accumulation rates were typical of moorlands elsewhere, and were reduced significantly only in the 6-burn treatment. However, impacts intensified gradually with burn frequency; each additional burn reduced the accumulation rates by 4.9 g m−2 yr−1 (peat) and 1.9 g C cm−2 yr−1, but did not prevent accumulation. Species diversity and the abundance of peat-forming species also increased with burn frequency. Our data challenge widely held perceptions that a move to 0 burning is essential for peat growth, and show that appropriate prescribed burning can both mitigate wildfire risk in a warmer world and produce relatively fast peat growth and sustained C sequestration

Material and Rational Feminisms

The panel will explore whether contemporary affirmations of materialism and biopolitical affect can be brought together with forms of rationalism and critically reflective thought to which they are typically opposed. How, we ask, can we produce from these different traditions of constructing alterity, a theory of practice adequate to the demands placed upon architectural history and theory today? As Rawes has noted, feminist and ecological thought alike have produced discourses in which reason and technology are sexed as ‘male’, and thus castigated as essentially oppres- sive, whereas the material, sensed or ecological are sexed as ‘female’. Opposing the continuation of this split as obstructive to the creation of an effectively ecological architecture, Rawes has turned both to feminist theories of the nonhuman — e.g. Haraway and Braidotti — and to the proto-ecological thinking of ‘ratio’ in Spinoza in order to argue for the possibility of a ‘humane’ architecture. Spencer will here pursue a similar objective, but through different means; Adorno and Horkheimer’s critique of the split between reason and the senses as the founding act of Enlightenment thought read, in dialectic of Enlightenment, through Homer’s The Odyssey as a gendered division between reason and matter. At the same time, and through the samemeans, he will also explore certain of the difficulties he per- ceives in the work of neo-materialists, such as Braidotti, around the discourse of bodies, subjects and their relationship to envi- ronments, including those produced through architecture

The Ecology of the Red Grouse

This account is a first attempt at describing the ecology of grouse at Moor House. A range of topics is dealt with including history, biology, behaviour and management
