Negotiating the British landscape

According to many accounts, a key paradigm for understanding art in Post WWII Britain is one of Englishness versus internationalism or abstraction versus realism . These terms have a rich inflection of meanings that have been subject to interrogation over the last few decades. Anwar Shemza came to Britain and practiced his art at a time when these competing claims were at their height. In a postcolonial reading entitled “Black Diaspora Artists in Britain: Three ‘Moments’ in Post-War Britain” Stuart Hall recently used David Scott’s framework of a ‘problem space’, that is discursively defined through questions, tensions and conjunctures, that couched the entry of what he describes as first waive British commonwealth artists into critical visibility in Britain. This can be characterized in part by the reviews of WG Archer and GM Butcher, both supporters of Shemza and prominent critics of the period. Hall includes Shemza in this framework that defines the work and his aspirations as constituted through the tensions of what was perceived to be anti-colonialist aims of modernism through universalism and the ‘nativist’ current in anti-colonial nationalism . This text will focus particularly on the problematic of Landscape as a ‘problem space’ of vernacular and modernism, over here and over there. The aim is not to define Shemza within the tradition of English landscape nor to exclude him but to position him within a discursive field of landscape and modernism in mid twentieth Century art.

G6f-like is an ITAM-containing collagen receptor in thrombocytes

Collagen activates mammalian platelets through a complex of the immunoglobulin (Ig) receptor GPVI and the Fc receptor γ-chain, which has an immunoreceptor tyrosine-based activation motif (ITAM). Cross-linking of GPVI mediates activation through the sequential activation of Src and Syk family kinases and activation of PLCγ2. Nucleated thrombocytes in fish are activated by collagen but lack an ortholog of GPVI. In this study we show that collagen activates trout thrombocytes in whole blood and under flow conditions through a Src kinase driven pathway. We identify the Ig receptor G6f-like as a collagen receptor and demonstrate in a cell line assay that it signals through its cytoplasmic ITAM. Using a morpholino for in vivo knock-down of G6f-like levels in zebrafish, we observed a marked delay or absence of occlusion of the venous and arterial systems in response to laser injury. Thus, G6f-like is a physiologically relevant collagen receptor in fish thrombocytes which signals through the same ITAM-based signalling pathway as mammalian GPVI, providing a novel example of convergent evolution.

Living the Revolution: urban communes & soviet socialism, 1917-1932

This book follows a revolutionary trend popular among young activists and would-be radicals after 1917, the formation of collective units of cohabitation and association known as 'urban communes'. In these spaces, activists tried to live what they understood as the 'socialist lifestyle', self-consciously putting Marxist and Bolshevik theories into practice. By telling the story of the urban communes, this book reveals how grand revolutionary ideals, such as collectivism, equality, proletarian ethics, and modern practice, were experienced, understood, and appropriated on a human level. This enables us to better understand the messy realities of the early Soviet state, showing how ideological beliefs and revolutionary contingencies actually came into being during this time.
