Exploring the benefits and pitfalls of using mutual wills

The purpose of this article is to consider a peculiar type of will known in equity as a mutual will. The major focus is a consideration of the interplay of the legal effect of mutual wills and the practical use of such wills, It is hoped that this discussion will assist legal practitioners in identifying those clients who may benefit from executing mutual wills, identifying those clients who might intend to execute mutual wills, advising clients as to the pros and cons of mutual wills and the benefits of accompanying such wills with a deed or contract.

Language, experience and professional learning (what Walter Benjamin can teach us)

This essay raises questions about how language educators might construct and further develop their epistemology of practice in and through the situations in which they work from day to day. The occasion for this paper is our work as guest editors of a special issue of L-1: Educational Studies in Language and Literature, when we invited L1 teachers to reflect on the role that language plays in their professional learning, whether it be in the form of conversations with peers, reflective writing, or by other means. We begin this essay by locating our reflections within our current policy context, namely the standards-based reforms that have come to dominate educational thinking around the world, offering a brief critique of the values and attitudes embedded within them. We then outline a philosophical framework as an alternative to the world-view reflected by such reforms, focusing specifically on the work of Walter Benjamin. In the final sections, we review our work as guest editors of the special issue of L-1, reflecting on what we have learned from the papers we have assembled for this issue, and locating our learning within the philosophical framework that we have drawn from Benjamin. We argue that it is timely for language educators to articulate the assumptions that inhere within their work, in contradistinction to the common sense embedded in standards. Thus we might begin to reconceptualise the relation between language, experience and professional learning in opposition to the hegemony of standards.

On the proximal Landweber Newton method for a class of nonsmooth convex problems

We consider a class of nonsmooth convex optimization problems where the objective function is a convex differentiable function regularized by the sum of the group reproducing kernel norm and (Formula presented.)-norm of the problem variables. This class of problems has many applications in variable selections such as the group LASSO and sparse group LASSO. In this paper, we propose a proximal Landweber Newton method for this class of convex optimization problems, and carry out the convergence and computational complexity analysis for this method. Theoretical analysis and numerical results show that the proposed algorithm is promising.
