    Flowfield-dependent variant method for moving-boundary problems

    A novel numerical scheme using the combination of flowfield-dependent variation method and arbitrary Lagrangian–Eulerian method is developed. This method is a mixed explicit–implicit numerical scheme, and its implicitness is dependent on the physical properties of the flowfield. The scheme is discretized using the finite-volume method to give flexibility in dealing with complicated geometries. The formulation itself yields a sparse matrix, which can be solved by using any iterative algorithm. Several benchmark problems in two-dimensional inviscid and viscous flow have been selected to validate the method. Good agreement with available experimental and numerical data in the literature has been obtained, thus showing its promising application in complex fluid–structure interaction problems

    Employee voice and collective formation in the Indian ITES-BPO industry

    The growth of the information technology enabled services-business process outsourcing industry calls for attention to employees' working conditions and rights. Can an independent organisation such as unites Pro (the union of information technology enabled services professionals) represent employees' interests and effectively work towards protecting their rights and improving their working conditions? A survey of unites members indicates that they identify with the need for such an organisation to deal with poor supervisory and managerial treatment, concerns for employee safety, grievances related to pay and workload, and even the indignities of favouritism

    Student Labour and Training in Digital Humanities

    Get PDF
    This article critiques the rhetoric of openness, accessibility and collaboration that features largely in digital humanities literature by examining the status of student labour, training, and funding within the discipline. The authors argue that the use of such rhetoric masks the hierarches that structure academic spaces, and that a shift to the digital does not eliminate these structural inequalities. Drawing on two surveys that assess student participation in DH projects (one for students, and one for faculty researchers), the article outlines the challenges currently faced by students working in the field, and suggests a set of best practices that might bridge the disparity between rhetoric and reality

    Research into the use of ICT and e-learning for work-based learning in the skills sector

    Get PDF
    This research has been commissioned by Becta to provide an evidence-based overview of the current use and effectiveness of work-based e-learning and its integration with more traditional learning methods. The specific objectives of the research were to: investigate the known impact of ICT and e-learning on the skills sector; and describe the ways in which ICT and e-learning can support key workforce development issues such as addressing skills gaps and achieving sustainability in training and development
