Unification of SU(2)xU(1) Using a Generalized Covariant Derivative and U(3)

A generalization of the Yang-Mills covariant derivative, that uses both vector and scalar fields and transforms as a 4-vector contracted with Dirac matrices, is used to simplify and unify the Glashow-Weinberg-Salam model. Since SU(3) assigns the wrong hypercharge to the Higgs boson, it is necessary to use a special representation of U(3) to obtain all the correct quantum numbers. A surplus gauge scalar boson emerges in the process, but it uncouples from all other particles.Comment: 12 pages, no figures. To be published in Int. J. Mod. Phys.

A Rare Second Year - Lake Ice Cover in the Canadian High Arctic

Colour Lake, Axel Heiberg Island, N.W.T. (79 25 N; 90 45 W), remained largely ice covered from autumn 1985 to summer 1987. This is a relatively rare event. Observations and measurements of the thickness and specific conductance of the lake ice cover were made at the end of the 1986 summer and again in the following spring. The residual ice cover (second-year ice with first-year ice beneath it) was significantly thicker and had a lower specific conductance than first-year ice formed in marginal leads (moat) that had been ice free in 1986. The first-year ice that grew beneath the residual ice cover had the lowest specific conductance. Distribution of snow on the lake was affected by the roughness of the second-year ice (as compared to the smoother moat ice) and differences in elevation between second-year (high) and moat ice.Key words: High Arctic, specific conductance, residual ice cover, snow distributionMots clés: Extrême-Arctique, conductivité spécifique, couverture de glace résiduelle, répartition de la neig

Collaboration and contestation in further and higher education partnerships in England: a Bourdieusian field analysis

Internationally, ‘College for All’ policies are creating new forms of vocational higher education (HE), and shifting relationships between HE and further education (FE) institutions. In this paper, we consider the way in which this is being implemented in England, drawing on a detailed qualitative case study of a regional HE–FE partnership to widen participation. We focus on the complex mix of collaboration and contestation that arose within it, and how these affected socially differentiated groups of students following high- and low-status routes through its provision. We outline Bourdieu’s concept of ‘field’ as a framework for our analysis and interpretation, including its theoretical ambiguities regarding the definition and scale of fields. Through hermeneutic dialogue between data and theory, we tentatively suggest that such partnerships represent bridges between HE and FE. These bridges are strong between higher-status institutions, but highly contested between lower-status institutions competing closely for distinction. We conclude that the trajectories and outcomes for socially disadvantaged students require attention and collective action to address the inequalities they face, and that our theoretical approach may have wider international relevance beyond the English case

Signals for Double Parton Scattering at the Fermilab Tevatron

Four double-parton scattering processes are examined at the Fermilab Tevatron energy. With optimized kinematical cuts and realistic parton level simulation for both signals and backgrounds, we find large samples of four-jet and three-jet+one-photon events with signal to background ratio being 20\%-30\%, and much cleaner signals from two-jet+two-photon and two-jet+$e^+e^-$ final states. The last channel may provide the first unambiguous observation of multiple parton interactions, even with the existing data sample accumulated by the Tevatron collider experiments.Comment: 7 pages, plain LaTeX, 2 tables, no figures.

Trust Within Reason: How to Trump the Hermeneutics of Suspicion on Campus

This chapter looks at the Prevent duty in the British university sector, arguing that social trust has been eroded by the process. It infantilises those who are expected to carry out this duty and empowers the state over the individual in ascertaining radicalisation on campus. The Prevent duty in its current shape homogenises the Muslim community and reduces the relationship of trust between the state and its minority population. Muslims in public professions struggle to step outside the frame of radicalisation and Islamic extremism. In an age where slivers of data about individuals and groups are marketable commodities, the disproportionate focus on Islamic extremism works to diminish Muslims and also diminishes the rest of us, who become complicit

Meta-analyses from a collaborative project in mobile lifelong learning

This paper focuses on the use of mobile technologies in relation to the aims of the European Union’s Lifelong Learning programme. First, we explain the background to the notion of mobile lifelong learning. We then present a methodological framework to analyse and identify good practices in mobile lifelong learning, based on the outcomes of the MOTILL project (“Mobile Technologies in Lifelong Learning: best practices”). In particular, we give an account of the methodology adopted to carry out meta-analyses of published literature and accounts of mobile learning experiences. Furthermore, we present the results of an implementation of our Evaluation Grid and the implications arising from it in terms of management, pedagogy, policies and ethical issues. Finally we discuss lessons learnt and future work

Towards a new privacy: Totalitarianism, emotion and management discourse

This article reviews some leadership and management literature dealing with emotional demands in professional contexts. An image of the ‘real self’, requiring emotional privacy, is highly valued by individuals subjected to intense emotional demands. It is argued that the ‘real self’ and emotional privacy ought to be defended against emotional ‘totalitarianism’ at work in high performance education contexts. The writings of George Orwell are employed both to develop an understanding of totalitarianism and consider how it can be resisted. Orwell prized the ideal of the ‘real self’, and it is argued that recent management literature does not give sufficient consideration to understanding and protecting ‘private’ emotions. It is argued that management discourse, demanding increasing levels of ‘emotional labour’, might be working from an imperfect or incomplete understanding of emotional experience as it is actually lived. An analysis of an article from The Academy of Management Review exemplifies managerial preoccupation with emotional effectiveness, without considering how such effectiveness connects with other life contexts. Ideas taken from Orwell are proposed to develop and fortify an ideal of emotional privacy, making explicit links between emotions and the society in which emotions are nurtured and understood

Light-Cone Quantization and Hadron Structure

In this talk, I review the use of the light-cone Fock expansion as a tractable and consistent description of relativistic many-body systems and bound states in quantum field theory and as a frame-independent representation of the physics of the QCD parton model. Nonperturbative methods for computing the spectrum and LC wavefunctions are briefly discussed. The light-cone Fock state representation of hadrons also describes quantum fluctuations containing intrinsic gluons, strangeness, and charm, and, in the case of nuclei, "hidden color". Fock state components of hadrons with small transverse size, such as those which dominate hard exclusive reactions, have small color dipole moments and thus diminished hadronic interactions; i.e., "color transparency". The use of light-cone Fock methods to compute loop amplitudes is illustrated by the example of the electron anomalous moment in QED. In other applications, such as the computation of the axial, magnetic, and quadrupole moments of light nuclei, the QCD relativistic Fock state description provides new insights which go well beyond the usual assumptions of traditional hadronic and nuclear physics.Comment: LaTex 36 pages, 3 figures.

Governing emotionally vulnerable subjects and ‘therapisation’ of social justice

In numerous countries, pessimism about enduring social and educational inequalities has produced a discernible therapeutic turn in education policy and practice, and a parallel rise in therapeutic understandings of social justice. Focusing on developments in England and Finland, this article explores the ways in which radical/critical conceptualisations of social justice privilege attention to psycho-emotional vulnerabilities. Extending older forms of psychologisation, therapeutic understandings of social justice in many contemporary radical/critical accounts resonate powerfully with the wider therapisation of popular culture and everyday life. Using theories of discursive power, we explore the new forms of governance, subjectivity and agency in mainstream therapeutic programmes, and evaluate their implications for pedagogies rooted in radical/critical notions of social justice
