Error analysis for an ALE evolving surface finite element method

We consider an arbitrary Lagrangian–Eulerian evolving surface finite element method for the numerical approximation of advection and diffusion of a conserved scalar quantity on a moving surface. We describe the method, prove optimal order error bounds and present numerical simulations that agree with the theoretical results

[Review of] Rita Dove, foreword. Multicultural Voices

Multicultural Voices gathers together an impressive array of writers and writings in a textbook aimed at secondary school readers. The book not only includes several of the more obvious and well-known authors -- Toni Morrison, Louise Erdrich, and Amy Tan, to name a few -- but also anthologizes a number of younger and less widely known writers whose contributions are equally provocative. While the bulk of the selections are either short stories or excerpts from novels (Zora Neale Hurston\u27s Their Eyes Were Watching God and Rudolfo Anaya\u27s Bless Me, Ultima are among those excerpted), the editors have also selected poetry, essays, and one short play, Denise Chavez\u27s The Flying Tortilla Man. Even though everyone will be able to think of a favorite author who is not represented (where is Amiri Baraka?), the range and quality of the book\u27s selections will make it a valuable classroom resource

Promoting ethical practice: moral agency in a hostile environment

A reflective journey in probation and social work is the subject of this paper, during which the profession?s value base has been challenged by neo-liberal political and economic orthodoxy that has threatened to suppress social work?s �service ideal? of social justice, wellbeing and relationship. The Anglo-Saxon polities, including the UK, have been in the vanguard of these developments. Writing from the UK, the author promotes the exercise of moral agency � of praxis � associated with upholding the �service ideal? in the face of these challenges. A good practice framework is presented identifying features a practitioner can demand of practice settings if they are to provide congruity between the realities of daily practice and the �service ideal?. This framework is the outcome of the author?s own reflective journey encompassing practice, practitioner research, management, academic study, teaching and writing. A UK Advanced Award in Social Work and PhD were staging posts in its formulation. It models cross-fertilisation of teaching, learning and practice: an exemplar for the integration of social work education in the world of practice. The framework has four domains for appraising practice settings: regulatory context, values of practice, support and development of staff, knowledge creation. It is illustrated by �worked? examples from practice and research. The examples demonstrate tensions within the values, policy and practice dynamic, in which policy has become technocratic, instrumentalist and hostile to the �service ideal?. The author uses the examples to show how standards of moral agency may be actively sought by the practitioner in adverse circumstances. Our response to the modern environment challenges us to hone our understanding of what we mean by good practice and develop ethical practice because the global orthodoxy?s spectacular collapse in 2008-9 creates a space in which ethical discourse can acquire renewed influence in professional, political and economic debate

Stability of Matter in Magnetic Fields

The proof of the stability of matter is three decades old, but the question of stability when arbitrarily large magnetic fields are taken into account was settled only recently. Even more recent is the solution to the question of the stability of relativistic matter when the electron motion is governed by the Dirac operator (together with Dirac's prescription of filling the ``negative energy sea"). When magnetic fields are included the question arises whether it is better to fill the negative energy sea of the free Dirac operator or of the Dirac operator with magnetic field. The answer is found to be that the former prescription is unstable while the latter is stable. This paper is a brief, nontechnical summary of recent work with M. Loss, J.P. Solovej and H.
