Charged, conformal non-relativistic hydrodynamics

We embed a holographic model of an U(1) charged fluid with Galilean invariance in string theory and calculate its specific heat capacity and Prandtl number. Such theories are generated by a R-symmetry twist along a null direction of a N=1 superconformal theory. We study the hydrodynamic properties of such systems employing ideas from the fluid-gravity correspondence.Comment: 31 pages, 1 figure, JHEP3 style, refs added, typos corrected, missing terms in spatial charge current and field corrections added, to be published in JHE

Communicating employability: the role of communicative competence for Zimbabwean highly skilled migrants in the UK

Skilled migration is an increasingly important topic for both policy and research internationally. OECD governments in particular are wrestling with tensions between their desire to use skilled migration to be on the winning side in the ‘global war for talent’ and their pandering to and/or attempts to outflank rising xenophobia. One aspect that has received relatively little attention is skilled migration from the African Commonwealth to the UK, a situation in which skilled migrants have relatively high levels of linguistic capital in the language of the host country. We focus here on the case of Zimbabwe. In spite of its popular image as a failed state, Zimbabwe has an exceptionally strong educational tradition and high levels of literacy and fluency in English. Drawing on 20 in-depth interviews of Zimbabwean highly skilled migrants, we explore the specific ways in which the communicative competences of these migrants with high formal levels of English operate in complex ways to shape their employability strategies and outcomes. We offer two main findings: first, that a dichotomy exists between their high level formal linguistic competence and their ability to communicate in less formal interactions, which challenges their employability, at least when they first move to the UK; and second, that they also lack, at least initially, the competence to narrativise their employability in ways that are culturally appropriate in England. Thus, to realise the full potential of their high levels of human capital, they need to learn how to communicate competently in a very different social and occupational milieu. Some have achieved this, but others continue to struggle

How non-native English-speaking staff are evaluated in linguistically diverse organizations: A sociolinguistic perspective

The aim of this paper is to examine the effects of evaluations of non-native speaking staff?s spoken English in international business settings. We adopt a sociolinguistic perspective on power and inequalities in linguistically diverse organizations in an Anglophone environment. The interpretive qualitative study draws on 54 interviews with non-native English-speaking staff in 19 UK business schools. We analyze, along the dimensions of status, solidarity and dynamism, the ways in which non-native speakers, on the basis of their spoken English, are evaluated by themselves and by listeners. We show how such evaluations refer to issues beyond the speaker?s linguistic fluency, and have consequences for her or his actions. The study contributes to the literature on language and power in international business through offering fine-grained insights into and elucidating how the interconnected evaluative processes impact the formation and perpetuation of organizational power relations and inequalities. It also puts forward implications for managing the officially monolingual, yet linguistically diverse organizations

QCD and strongly coupled gauge theories : challenges and perspectives

We highlight the progress, current status, and open challenges of QCD-driven physics, in theory and in experiment. We discuss how the strong interaction is intimately connected to a broad sweep of physical problems, in settings ranging from astrophysics and cosmology to strongly coupled, complex systems in particle and condensed-matter physics, as well as to searches for physics beyond the Standard Model. We also discuss how success in describing the strong interaction impacts other fields, and, in turn, how such subjects can impact studies of the strong interaction. In the course of the work we offer a perspective on the many research streams which flow into and out of QCD, as well as a vision for future developments.Peer reviewe

Advancing Malaysian Practice-Based Education

As an international language of communication, English in Malaysia is considered a critical language of commerce for Malaysia to maintain its competitive edge and for graduates to work and practise in a global context. It is a key to successful education for practice for these students. The official role of English in Malaysia is that of a second language (L2), with Malay as the first language and Tamil or Chinese as the third. The recent growth of the use of English in the “outer circle” as delineated by Kachru (1985) in countries such as Singapore and Malaysia has been extensive. In Malaysia the growth of English has been steady, and increased efforts have been made by English language researchers and teachers to encourage English proficiency among school students, particularly secondary school students

My English, My Literature: Owning Our African Englishes and Literatures

Despite this era of World Englishes, the question of whose language African novelists use and, hence, whose literature they produce remains. It is not uncommon for readers of African literature to assume that what they read from Africa is a translation from African indigenous languages, but who owns the English language that African authors use in their writing? Are these authors using a borrowed language, or is the English they use their own? And whose culture is expressed in the writing? Using Margaret Ogola’s novel entitled The River and the Source within the World Englishes paradigm, this current work proposes that the English Ogola and other African authors use are entirely their own and the cultures they express fully African
