Women artists of the international avant-garde: the case of "Abstraction-Création" (1931-1936)

Women’s contribution to abstract art in the interwar period is a subject that, to date, has received very little attention. In this article we deal with the untold story of the participation of women artists in Abstraction-Création, the foremost international group dedicated to abstract art in the 1930s. Founded in Paris in 1931, the group took on the work of two previous collectives to become a platform for the dissemination and promotion of abstract art and consisted of around a hundred members. Twelve of these were women, whose writings and works were published in the group’s annual magazine, abstraction creátion art non figuratif (1932-1936), and who participated in a number of the group’s exhibitions. Compared to what had occurred in previous groups, the participation of women, although reduced in number, was comparable to that of the male artists and being members of the group had a generally positive impact on the women’s careers. However, all this came at the expense of relinquishing any gender specificity in their work and the public presentation of it, and demonstrates that the normalization of women’s contributions to the avant-garde could only be brought about alongside a questioning of the more dogmatic views of modernity.

A plasma membrane Ca<sup>2+-ATPase (PMCA) from the liver fluke, Fasciola hepatica</em>

Fasciolosis is a parasitic infection by the liver fluke Fasciola hepatica, which costs the global agricultural community over US $2 billion per year. Its prevalence is rising due to factors such as climate change and drug resistance. ATP-dependent membrane transporters are considered good potential drug targets as they are essential for cellular processes and are in an exposed, accessible position in the cell. Immunolocalisation studies demonstrated that a plasma membrane calcium ATPase (PMCA) was localised to the parenchymal tissue in F. hepatica. The coding sequence for a F. hepatica PMCA (FhPMCA) has been obtained. This sequence encodes a 1,163 amino acid protein which contains motifs which are commonly conserved in PMCAs. Molecular modelling predicted that the protein has 10 transmembrane segments which include a potential calcium ion binding site and phosphorylation motif. FhPMCA interacts with the calmodulin-like protein FhCaM1, but not the related proteins FhCaM2 or FhCaM3, in a calcium-ion dependent manner. This interaction occurs through a region in the C-terminal region of FhPMCA which most likely adopts an a-helical conformation. When FhPMCA was heterologously expressed in a budding yeast strain deleted for its PMCA (Pmc1p), it restored viability. Microsomes prepared from these yeast cells had calcium ion stimulated ATPase activity which was inhibited by the known PMCA inhibitors, bisphenol and eosin. The potential of FhPMCA as a new drug target is discussed.

INFLUENCE OF CORE POLARIZATION ON THE ELECTRON-AFFINITY OF CA

We have developed a method, based on the use of B-spline basis sets and model potentials, for determining properties of systems with two or three electrons outside a polarizable closed-shell core. It is applied to the calculation of the electron affinity of Ca and the resulting value of 17.7 meV is in excellent agreement with the most recent experiments. It is found that the dielectronic core-valence interaction reduces the electron affinity by 39.5 meV.

Knowledge Formation and the Great Divergence between China and Europe: Manuscripts and Printed Books, ca. 581–1840

Literature dealing with the history of Chinese printed books and printing is voluminous. Yet studies of how knowledge in general and utilitarian forms of knowledge in particular were generated, accumulated and circulated by printed books and their relationship with the long-term socio-economic transformation of China are rare. This paper aims to open up the subject by examining the long-term trends in the production of manuscripts and books and focusing on the connections between the generation and dissemination of useful knowledge in China and the production and circulation of printed books over the centuries and dynasties from circa 581 to 1840 compared to Europe. It connects trends in this indicator for knowledge formation and diffusion to economic growth, urbanization, changes in higher forms of education, the rise of literacy, the development of printing technologies, and changes in perceptions of the natural world. It concludes that human capital formation in China probably proceeded at a slower rate,which is relevant for narratives of the “divergence” between China and Europe.

‘A dance for all the outcasts’: Class and Postcolonialism in Brendan Behan’s An Giall and The Hostage

As Susan Bassnett and Harish Trivedi argue, ‘translation does not happen in a vacuum, but in a continuum; it is not an isolated act, it is part of an ongoing process of intercultural transfer’. In understanding Brendan Behan's most celebrated and controversial translation, of his spare Irish language play An Giall (1958) to its riotous English counterpart The Hostage (1958), understanding the problematic ‘intercultural transfer’ between British and Irish life in the 1950s is crucial. Comparisons between both works reveal significant changes that illuminate Behan's relationship with both nations and provide a sometimes oblique metacommentary regarding his most pressing political and personal anxieties. Yet for all their differences, the plays also share a common desire to transcend the divisions forged by the colonial experience through critical understandings of life on either side of the Irish Sea. In this essay, I argue that Behan's act of transculturation reveals a great deal more reflexivity and depth than many of his critics would allow, developing an iconoclastic dialogue between British and Irish mid-century life.
