You need only one bull to cover fifty cows: Zulu women and 'traditional' dress

African Studies Seminar series. Paper presented June 1987This paper tries to place the contemporary dress of married Zulu women into a broad historical framework. It therefore addresses the the problem of why, despite radical economic and political transformations, some of the present conventions of female dress have remained virtually unchanged since Shakan times.(1) By looking particularly at the history of the institution of marriage, it attempts to demonstrate how the meanings ascribed to, but also the roles of these conventions have been affected by the codification of so-called customary law and the growth of migrant labour. Given the paucity of information on past perceptions and interpretations of female dress it must be pointed out, though, that many of the observations which follow are necessarily speculative

How are stakeholders with autism spectrum disorder included in the social validation of augmentative and alternative communication research? A scoping review

INTRODUCTION : Social validation or the inclusion of stakeholders in the research process is beneficial, as it may decrease bias, increases efficacy, and prevents harm. For direct stakeholders such as individuals with autism spectrum disorder (ASD), social validation has mostly included participants who do not experience significant speech, language, and communication limitations while frequently omitting individuals with ASD who have complex communication needs (CCN). The presence of CCN indicates that augmentative and alternative communication (AAC) strategies are needed for individuals to express themselves. Social validation should not be limited to being participants in an intervention but should include involvement in the research process. This requires an understanding of the current trends, levels, and mechanisms of involvement in AAC research. PURPOSE : This review aimed to identify and describe the inclusion of direct stakeholders with ASD in the social validation of AAC research. METHOD : A scoping review was conducted following the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews) methodology to identify AAC research that included stakeholders with ASD (direct and indirect) for social validation and to evaluate their level of involvement using the Typology of Youth Participation and Empowerment pyramid framework. RESULTS : Twenty-four studies were identified. Studies primarily included indirect stakeholders (e.g., caregivers) giving in-depth perspectives, while direct stakeholders were limited to being intervention participants. CONCLUSIONS : Voices of direct stakeholders with ASD and CCN remain limited or excluded in research. Reasons for the exclusion of individuals with ASD and CCN from research and strategies for future inclusion are raised and discussed.The Andrew W.

Assessment of basis sets for F12 explicitly-correlated molecular electronic-structure methods

International audienceOne-electron basis sets for F12 explicitly-correlated molecular electronic-structure methods are assessed by analysing the accuracy of Hartree-Fock energies and valence-only second-order correlation energies of a test set of 106 small molecules containing the atoms H, C, N, O and F. For these molecules, near Hartree-Fock-limit energies and benchmark second-order correlation energies (accurate to within 99.95% of the basis-set limit) are provided. Absolute energies are analysed as well as the Hartree-Fock and second-order correlation contributions to the atomisation energies of the molecules. Standard basis sets such as the Karlsruhe def2-TZVPP and def2-QZVPP sets and the augmented correlation-consistent polarised valence X-tuple zeta (aug-cc-pVXZ, X = D, T, Q, 5) sets are compared with the specialised cc-pVXZ-F12 (X = D, T, Q) sets that were recently optimised by Peterson and co-workers [J. Chem. Phys. 128, 084102 (2008)] for use in F12 theory. The results obtained from F12 explicitly-correlated molecular electronic-structure calculations are compared with those that are obtained by standard electronic-structure calculations followed by basis-set extrapolation based on the X-3 convergence behaviour of the aug-cc-pVXZ basis sets. The most important conclusions are that the cc-pVXZ-F12 sets are the preferred basis sets for F12 theory and that the X-3 extrapolation from the aug-cc-pVQZ and aug-cc-pV5Z is slightly more accurate than F12 theory in the cc-pVTZ-F12 basis but less accurate than F12 theory in the cc-pVQZ-F12 basis

Accurate computations of the structures and binding energies of the imidazole ... benzene and pyrrole ... benzene complexes

Using explicitly-correlated coupled-cluster theory with single and double excitations, the intermolecular distances and interaction energies of the T-shaped imidazole⋯⋯benzene and pyrrole⋯⋯benzene complexes have been computed in a large augmented correlation-consistent quadruple-zeta basis set, adding also corrections for connected triple excitations and remaining basis-set-superposition errors. The results of these computations are used to assess other methods such as Møller–Plesset perturbation theory (MP2), spin-component-scaled MP2 theory, dispersion-weighted MP2 theory, interference-corrected explicitly-correlated MP2 theory, dispersion-corrected double-hybrid density-functional theory (DFT), DFT-based symmetry-adapted perturbation theory, the random-phase approximation, explicitly-correlated ring-coupled-cluster-doubles theory, and double-hybrid DFT with a correlation energy computed in the random-phase approximation

Mapping Modernisms : Art, Indigeneity, Colonialism

"Mapping Modernisms brings together scholars working around the world to address the modern arts produced by indigenous and colonized artists. Expanding the contours of modernity and its visual products, the contributors illustrate how these artists engaged with ideas of Primitivism through visual forms and philosophical ideas. Although often overlooked in the literature on global modernisms, artists, artworks, and art patrons moved within and across national and imperial borders, carrying, appropriating, or translating objects, images, and ideas. These itineraries made up the dense networks of modern life, contributing to the crafting of modern subjectivities and of local, transnationally inflected modernisms. Addressing the silence on indigeneity in established narratives of modernism, the contributors decenter art history's traditional Western orientation and prompt a re-evaluation of canonical understandings of twentieth-century art history." -- Publisher's website
