The lightest neutralino in the MNSSM

We examine the allowed mass range of the lightest neutralino within the Minimal Non--minimal Supersymmetric Standard Model. Being absolutely stable if R-parity is conserved this lightest neutralino is a candidate for the dark matter of the universe. We establish the theoretical upper bound on the lightest neutralino mass and obtain an approximate solution for this mass.Comment: Submitted for the SUSY07 proceedings, 4 pages, LaTeX, 3 eps figures, some minor changes to the tex

Giant frequency-selective near-field energy transfer in active--passive structures

We apply a fluctuation electrodynamics framework in combination with semianalytical (dipolar) approximations to study amplified spontaneous energy transfer (ASET) between active and passive bodies. We consider near-field energy transfer between semi-infinite planar media and spherical structures (dimers and lattices) subject to gain, and show that the combination of loss compensation and near-field enhancement (achieved by the proximity, enhanced interactions, and tuning of subwavelength resonances) in these structures can result in orders of magnitude ASET enhancements below the lasing threshold. We examine various possible geometric configurations, including realistic materials, and describe optimal conditions for enhancing ASET, showing that the latter depends sensitively on both geometry and gain, enabling efficient and tunable gain-assisted energy extraction from structured surfaces

Misconduct resistance: the management of restricted drugs in the Western Australian public health service

We employ institutional theory to develop and present a framework – involving institutional drivers, organisational reactions, and outcomes – to examine and further understand misconduct resistance in public sector organisations. This framework is applied to an examination of efforts in the Western Australian public health service to prevent misconduct in the management of restricted drugs. We begin by clarifying a definition of misconduct resistance and then synthesise the extant literature develop a typology and framework of corruption resistance. The second part of the paper is a study in which the framework is applied to an examination of why and how the Western Australian public health service has endeavoured to prevent misconduct in the management of restricted drugs. Top-down imposition of regulations rather than shifts in individual employee attitudes is found. The paper concludes by outlining the potential contributions to theory and practice in approaches to increasing misconduct resistance in public health care organisations

Hidden persuaders on film: Exploring young people’s lived experience through visual essays

The Hidden Persuaders research group examines ‘brainwashing’ in the Cold War for the roles, real and imagined, played by psychologists, psychiatrists and psychoanalysts. Our project engaged young people in an exploration of the history of fears about brainwashing, and enabled them to explore their thoughts and ideas about the forces that shape their lives in contemporary society, through film-making. Working with three schools in the Camden area of London, our partners at the Derek Jarman Lab media hub, Birkbeck, University of London, and an artist facilitator (Lizzie Burns), we invited Year 12 students to learn filming and editing to create their own short video essays. The use of this format resulted in a significant depth of engagement and generated a wealth of creative responses. The various stages of the film-making process enabled the students to work out the terms of an argument and to consider how best to express it concisely. In the resulting films, they came up with a variety of forms of visual storytelling, and used the medium to express their thoughts, feelings and ideas in diverse ways, giving us a range of new perspectives which we could consider in relation to our historical research
