Mixed communities: a new approach to spatially-concentrated poverty in England

This article examines the adoption, by the New Labour government, of a mixed communities approach to the renewal of disadvantaged neighbourhoods in England. It argues that while there are continuities with previous policy, the new approach represents a more neoliberal policy turn in three respects: its identification of concentrated poverty as the problem; its faith in market-led regeneration; and its alignment with a new urban policy agenda in which cities are gentrified and remodelled as sites for capital accumulation through entrepreneurial local governance. The article then draws on evidence from the early phases of the evaluation of the mixed community demonstration projects to explore how the new policy approach is playing out at a local level, where it is layered upon existing policies, politics and institutional relationships. Tensions between neighbourhood and strategic interests, community and capital are evident as the local projects attempt neighbourhood transformation, while seeking to protect the rights and interests of existing residents. Extensive community consultation efforts run parallel with emergent governance structures, in which local state and capital interests combine and communities may effectively be disempowered. Policies and structures are still evolving and it is not yet entirely clear how these tensions will be resolved, especially in the light of a collapsing housing market, increased poverty and demand for affordable housing, and a shortage of private investment.

A new approach to neuroimaging with magnetoencephalography

We discuss the application of beamforming techniques to the field of magnetoencephalography (MEG). We argue that beamformers have given us an insight into the dynamics of oscillatory changes across the cortex not explored previously with traditional analysis techniques that rely on averaged evoked responses. We review several experiments that have used beamformers, with special emphasis on those in which the results have been compared to those observed in functional magnetic resonance imaging (fMRI) and on those studying induced phenomena. We suggest that the success of the beamformer technique, despite the assumption that there are no linear interactions between the mesoscopic local field potentials across distinct cortical areas, may tell us something of the balance between functional integration and segregation in the human brain. What is more, MEG beamformer analysis facilitates the study of these complex interactions within cortical networks that are involved in both sensory-motor and cognitive processes. © 2005 Wiley-Liss, Inc.

New strategy to overcome the intrinsic difficulty of phospholipids solubilisation and delivery to the eye

Purpose: Lipids play a vital role at interfaces such as the tear film in the protection of the anterior eye. Their role is to act as lubricants and reduce surface and interfacial tension. Although there is a lack of appropriate methods to solubilize and dilute phospholipids to the tear film. Here, we report that styrene-maleic acid copolymers (PSMA), can form polymer–lipid complexes in the form of monodisperse nanometric particles, which can easily solubilise these phospholipid molecules by avoiding for example, the use of any kind of surfactant. Method: The interactions of PSMA with phospholipids have been studied by its adsorption from aqueous solutions into monolayers of dimyristoyl-phosphorylcholine (DMPC). The Langmuir trough (LT) technique is used to study this pH-dependant complex formation. The formed nanoparticles have been also analysed by 31P NMR, particle size distribution by light scattering (DLS) and morphology by electron microscopy (SEM). Results: The LT has been found to be a useful technique for in vitro simulation of in vivo lipid layer behaviour: The limiting surface pressure of unstable tear films ranges between 20 and 30 mN/m. More stable tear films show an increase in surface pressure, within the range of 35–45 mN/m. The DMPC monolayers have a limiting surface pressure of 38 mN/m (water), and 45 mN/m (pH 4 buffer), and the PSMA-DMPC complexes formed at pH 4 have a value of 42 mN/m, which resembles that of the stable tear film. The average particle size distribution is 53 ± 10 nm with a low polydispersity index (PDI) of 0.24 ± 0.03. Conclusions: New biocompatible and cheap lipid solubilising agents such as PSMA can be used for the study of the tear film composition and properties. These polymer–lipid complexes in the form of nanoparticles can be used to solubilise and release in a controlled way other hydrophobic molecules such as some drugs or proteins.

New approaches to North Korean politics after reunification:the search for a common Korean identity

Whilst most of the literature focusing on the Korean peninsula has concentrated on how to achieve unification through confidence-building measures, dialogues, negotiation and diplomacy, little attention has been paid to how a unified Korean identity, a core component of any potential reunification scheme could develop and be sustained. The paper addresses this gap by: (1) defining what national identity is, and how Korean identities have been formed, (2) outlining how both South and North Korea have understood and used the concept of national identity, (3) suggesting possible grounds on which the two Koreas could build a new, common national identity. © 2014 The Regents of the University of California.

Salting out in organic solvents:a new route to carbon nanotube bundle engineering

In this study we investigate salt effects on bundle formation of carbon nanotubes (CNTs) dispersed in an organic solvent, N-methyl-2-pyrrolidone (NMP). Addition of NaI salt leads to self-assembly of CNTs into well-recognizable bundles. It is possible to control the size of the CNT bundles by varying the salt concentration. © the Owner Societies 2011.

Brain oscillations and connectivity in autism spectrum disorders (ASD):new approaches to methodology, measurement and modelling

Although atypical social behaviour remains a key characterisation of ASD, the presence ofsensory and perceptual abnormalities has been given a more central role in recentclassification changes. An understanding of the origins of such aberrations could thus prove afruitful focus for ASD research. Early neurocognitive models of ASD suggested that thestudy of high frequency activity in the brain as a measure of cortical connectivity mightprovide the key to understanding the neural correlates of sensory and perceptual deviations inASD. As our review shows, the findings from subsequent research have been inconsistent,with a lack of agreement about the nature of any high frequency disturbances in ASD brains.Based on the application of new techniques using more sophisticated measures of brainsynchronisation, direction of information flow, and invoking the coupling between high andlow frequency bands, we propose a framework which could reconcile apparently conflictingfindings in this area and would be consistent both with emerging neurocognitive models ofautism and with the heterogeneity of the condition.

The Routledge companion to accounting and risk

To date, there has been little consideration of the many different ways in which accounting and risk intersect, despite organisations being more determined than ever to build resilience against potential risks. This comprehensive volume overcomes this gap by providing an overview of the field, drawing together current knowledge of risk in a wide range of different accounting contexts.
