ICT and applied linguistics – A project approach

This workshop discusses and shows examples of student-created ICT projects developed as part of Applied Linguistics coursework. A “Top 20 Site Search” asked students to select sites to recommend to other (novice) teachers of English. Besides student learning resources, they also located resources of use to teachers for lesson planning, test development, and so on. A similar project was conducted with students in a graduate Materials Design course. Students submitted their top sites, which were compiled and made available on web CT. In class, they took turns showing the best features of their favorite sites. Perhaps the best example of learner motivation linked to IT comes from undergraduate courses in first and second language acquisition. Although not explicitly asked to use IT, the better projects integrated digital video clips so as to show samples collected during their research. Another example is a fieldwork “scrapbook” presented via Power Point. It is clear that students went well beyond the requirements of the assignment when implementing and presenting their projects. IT was obviously a valuable tool and even a motivator for students as they explored language learning issues, processes and concepts

Gravitational Effects in Quantum Mechanics

To date, both quantum theory, and Einstein's theory of general relativity have passed every experimental test in their respective regimes. Nevertheless, almost since their inception, there has been debate surrounding whether they should be unified and by now there exists strong theoretical arguments pointing to the necessity of quantising the gravitational field. In recent years, a number of experiments have been proposed which, if successful, should give insight into features at the Planck scale. Here we review some of the motivations, from the perspective of semi-classical arguments, to expect new physical effects at the overlap of quantum theory and general relativity. We conclude with a short introduction to some of the proposals being made to facilitate empirical verification.Comment: 24 pages, 3 figures, review article. Submitted to Contemporary Physic

Understanding the information needs of users of public information about higher education

Report to HEFCE by Oakleigh Consulting and Staffordshire University. "This study's aims were to carry out research into understanding the needs of intended users (primarily prospective students but with some focus on their advisors and employers) of public information on higher education (HE). The work focussed on England, but also took into account Wales, Scotland and Northern Ireland where relevant." - Page 1

Quantum non-Gaussianity witnesses in the phase space

We address detection of quantum non-Gaussian states, i.e. nonclassical states that cannot be expressed as a convex mixture of Gaussian states, and present a method to derive a new family of criteria based on generic linear functionals. We then specialise this method to derive witnesses based on $s$-parametrized quasiprobability functions, generalising previous criteria based on the Wigner function. In particular we discuss in detail and analyse the properties of Husimi Q-function based witnesses and prove that they are often more effective than previous criteria in detecting quantum non-Gaussianity of various kinds of non-Gaussian states evolving in a lossy channel.Comment: 9 pages, 6 figure

Bisector and zero-macrospin co-rotational systems for shell elements

A principal issue in any co-rotational approach for large displacement analysis of plates and shells is associated with the specific choice of the local reference system in relation to the current deformed element configuration. Previous approaches utilised local co-rotational systems, which are invariant to nodal ordering, a characteristic that is deemed desirable on several fronts; however, the associated definitions of the local reference system suffered from a range of shortcomings, including undue complexity, dependence on the local element formulation and possibly an asymmetric tangent stiffness matrix. In this paper, new definitions of the local co-rotational system are proposed for quadrilateral and triangular shell elements, which achieve the invariance characteristic to the nodal ordering in a relatively simple manner and address the aforementioned shortcomings. The proposed definitions utilise only the nodal coordinates in the deformed configuration, where two alternative definitions, namely, bisector and zero-macrospin definitions, are presented for each of quadrilateral and triangular finite elements. In each case, the co-rotational transformations linking the local and global element entities are presented, highlighting the simplicity of the proposed approach. Several numerical examples are finally presented to demonstrate the effectiveness and relative accuracy of the alternative definitions proposed for the local co-rotational system

Optimisation of two-dimensional ion trap arrays for quantum simulation

The optimisation of two-dimensional (2D) lattice ion trap geometries for trapped ion quantum simulation is investigated. The geometry is optimised for the highest ratio of ion-ion interaction rate to decoherence rate. To calculate the electric field of such array geometries a numerical simulation based on a "Biot-Savart like law" method is used. In this article we will focus on square, hexagonal and centre rectangular lattices for optimisation. A method for maximising the homogeneity of trapping site properties over an array is presented for arrays of a range of sizes. We show how both the polygon radii and separations scale to optimise the ratio between the interaction and decoherence rate. The optimal polygon radius and separation for a 2D lattice is found to be a function of the ratio between rf voltage and drive frequency applied to the array. We then provide a case study for 171Yb+ ions to show how a two-dimensional quantum simulator array could be designed

Agency's Law and Ethics of Hiring a Diverse Workforce

This paper is designed to look at the laws and ethics of agency of hiring a diverse workforce in the government agency. Working as a consultant, it is significant to know about the important laws, factors, and projection of ethical and lawful approaches of the agency. This paper selects ‘Food and Drug Administration’ of the U.S for exploring the practices of their human resource department. The FDA is a part of the U.S. Department of Health and Human Services, which looks after the issues of protection and progression of the public health. It is one of the prime research and scientific agencies which controls safety of the food consumed in the US. Its area of governance also includes drugs, pharmaceutics and medical devices. Its headquarter is in Montgomery County, Maryland. FDA focuses on recruiting and selecting the best possible resources which are not only qualified and highly skilled, but also keen in bringing a change within their scope of job. FDA has 10,000 employees which are considered as the strong workforce and the most priced asset of the U.S (www.fda.gov)

Enhanced dielectrophoresis of nanocolloids by dimer formation

We investigate the dielectrophoretic motion of charge-neutral, polarizable nanocolloids through molecular dynamics simulations. Comparison to analytical results derived for continuum systems shows that the discrete charge distributions on the nanocolloids have a significant impact on their coupling to the external field. Aggregation of nanocolloids leads to enhanced dielectrophoretic transport, provided that increase in the dipole moment upon aggregation can overcome the related increase in friction. The dimer orientation and the exact structure of the nanocolloid charge distribution are shown to be important in the enhanced transport
