'Second-wave' black feminist periodicals in Britain
This article offers a long overdue exploration of black feminist periodicals in the UK during the period of second-wave feminism. In it, the author examines four feminist periodicalsâFOWAAD, Speak Out, We Are Here and Muktiâin order to trace the development of black feminism in Britain and to investigate the extent to which black feminist periodicals in the UK became key sites for the development of a black feminist political critique that was aimed at three targets: the (white) feminist movement, the racist British state, and patriarchal structures within migrant communities. Insisting on the interconnected nature of gendered, race and class oppression in a manner that foreshadowed many contemporary theoretical developments around the politics of intersectionality, these periodicals provide vital insights into the black womenâs movement and its complicated relationship to larger radical black movements and the concept of âpolitical blacknessâ
Fast Decomposition of Large Nonnegative Tensors
International audienceIn Signal processing, tensor decompositions have gained in popularity this last decade. In the meantime, the volume of data to be processed has drastically increased. This calls for novel methods to handle Big Data tensors. Since most of these huge data are issued from physical measurements, which are intrinsically real nonnegative, being able to compress nonnegative tensors has become mandatory. Following recent works on HOSVD compression for Big Data, we detail solutions to decompose a nonnegative tensor into decomposable terms in a compressed domain
Accessing the content of nineteenth-century periodicals: the Science in the Nineteenth-Century Periodical project
Nineteenth-century periodicals significantly outnumber books from that era, and present historians with an immensely valuable set of sources, but their use is constrained by the difficulty of identifying relevant material. For many periodicals, contents pages and volume indexes have been the only guide, and the few subject indexes that exist usually provide only an indication of the subjects mentioned in the article titles. By contrast, the Science in the Nineteenth-Century Periodical project (SciPer) indexed the science content of general-interest periodicals by skim-reading the entire text. The projectâs approach to indexing is described and the relative merits of indexing and digitization in aiding researchers to locate relevant material are discussed. The article concludes that, notwithstanding the more sophisticated search interfaces of more recent retrodigitization projects, human indexing still has an important role to play in providing access to the content of historic periodicals and in mapping their data structure
