The founding Treaties of the European Union (EU) provide the Commission with bureaucratic structures and functions, and the authority to take a political leadership role in the integration process. However, the legitimacy of the Commission's authority to act either as a bureaucracy or as a political institution is periodically contested, as is the authority and leadership of its President. Max Weber's theory of the legitimation of authority suggests itself in this context as a working tool for assessing the nature of institutional and individual authority and leadership in the Commission and the broader EU context. Weber's typology of authority offers both an understanding of the changes in the Commission's fortunes within the 'would-be polity' of the European institutions, and an appraisal of claims to authority at the individual level by the Commission President. When applied to two contrasting moments in the Commission's life during the presidency of Jacques Delors (the generating of the White Papers of 1985 and 1993), Weber's typology provides an explanation for the evolution of the legitimation of these forms of authority in terms of, first, the Union's imperfect provisions for legitimate claims to leadership authority on 'charismatic' grounds and, second, the absence in the Union of resources for leadership legitimacy based on 'traditional'-type authority, such as explicit, popular, or party political European-wide support for the project of European union. These are resources which, if present in the EU, would legitimise calls to reform the EU's institutions in the direction of more integration and a more federal polity. The case studies offer an appraisal of the functioning and malfunctioning of authority within the Union, as well as a critical assessment of the applicability of the Weberian model to the legitimation of authority in the EU.

In this paper we consider how functional Magnetic Resonance Imaging (fMRI) has been used to study cortical connectivity in autism and autistic spectrum disorders (ASD). We discuss those studies that have contributed to the evidence supporting a model of disordered cortical connectivity in autism and (ASD), with a focusing emphasis on the application to research into the underconnectivity model. We note that the analytical techniques employed are limited and do not allow interpretation in terms of effective, or directional connectivity, nor do they provide information about the temporal or spectral characteristics of the functional networks being studied. We highlight how currently the features of neural generators that are being assessed by functional connectivity in fMRI are unclear. In addition, we note the importance in clinical studies of considering the consequences of task choice for the nature of the imaging data that can be collected and also of individual differences in participant state and trait characteristics for the accurate interpretation of imaging data. We discuss how alternative techniques such as EEG/MEG may address the limitations of fMRI in assessing brain connectivity, and additionally consider the potential of multimodal approaches. We conclude that fMRI has made significant contributions towards our understanding of the brain in terms of neural systems but that the conclusions drawn from its application in the sphere of autism research need to be approached with caution. It is important in research of this kind that we are aware of the need to examine the methodological and analytical techniques closely when applying findings in clinical populations, not only when they are used to support the development of theoretical models but also to inform diagnostic or treatment decisions.

Beta-cell failure coupled with insulin resistance is a key factor in the development of type 2 diabetes. Changes in circulating levels of adipokines, factors released from adipose tissue, form a significant link between excessive adiposity in obesity and both aforementioned factors. In this review we consider the published evidence for the role of individual adipokines on the function, proliferation, death and failure of beta-cells, focusing on those reported to have the most significant effects (leptin, adiponectin, TNFa, resistin, visfatin, DPP-IV and apelin). It is apparent that some adipokines have beneficial effects whereas others have detrimental properties; the overall contribution to beta-cell failure of changed concentrations of adipokines in the blood of obese pre-diabetic subjects will be highly dependent on the balance between these effects and the interactions between the adipokines which act on the beta-cell via a number of intersecting intracellular signalling pathways. We emphasise the importance, and comparative dearth, of studies into the combined effects of adipokines on beta-cells.

This paper examines the 'ideological grip' of personalization. It does so empirically, tracking the trajectory of personalization through austerity budgeting in one English local authority. In this case, personalization continued to signify hope and liberation even though the most draconian cuts in the Council's history effectively rendered personalization a practical impossibility. This requires critical theorization. Two bodies of theory are interrogated. First Boltanski's sociology of critique, and, in particular, his notion of managerial domination illuminate the way in which change imperatives and crises come to cement ideological formations. Here it is argued that the articulation of personalization with transformation lends itself to managerial domination. It is further argued, though, that while institutional actors may be able to manipulate the symbolic to evade, what Boltanski terms, deconstructionist critique, this cannot entirely explain the hold of this particular discourse. Here, the Lacanian concept of enjoyment is deployed to interrogate its extra-symbolic function and fantasmatic form. Finally, the paper explores the political implications of such affective attachment and, in particular, the guarantee that personalization offers in a period of welfare state decline. © The Author(s) 2012.

The aim of this research was to investigate the molecular interactions occurring in the formulation of non-ionic surfactant based vesicles composed monopalmitoyl glycerol (MPG), cholesterol (Chol) and dicetyl phosphate (DCP). In the formulation of these vesicles, the thermodynamic attributes and surfactant interactions based on molecular dynamics, Langmuir monolayer studies, differential scanning calorimetry (DSC), hot stage microscopy and thermogravimetric analysis (TGA) were investigated. Initially the melting points of the components individually, and combined at a 5:4:1 MPG:Chol:DCP weight ratio, were investigated; the results show that lower (90 C) than previously reported (120-140 C) temperatures could be adopted to produce molten surfactants for the production of niosomes. This was advantageous for surfactant stability; whilst TGA studies show that the individual components were stable to above 200 C, the 5:4:1 MPG:Chol:DCP mixture show ∼2% surfactant degradation at 140 C, compared to 0.01% was measured at 90 C. Niosomes formed at this lower temperature offered comparable characteristics to vesicles prepared using higher temperatures commonly reported in literature. In the formation of niosome vesicles, cholesterol also played a key role. Langmuir monolayer studies demonstrated that intercalation of cholesterol in the monolayer did not occur in the MPG:Chol:DCP (5:4:1 weight ratio) mixture. This suggests cholesterol may support bilayer assembly, with molecular simulation studies also demonstrating that vesicles cannot be built without the addition of cholesterol, with higher concentrations of cholesterol (5:4:1 vs 5:2:1, MPG:Chol:DCP) decreasing the time required for niosome assembly. © 2013 Elsevier B.V.

Study Design. An immunohistological study of surgical specimens of human intervertebral disc.Objective.To examine the presence of pleiotrophin in diseased or damaged intervertebral disc tissue and the association between its presence and the extent of tissue vascularization and innervation.Summary of Background Data. Increased levels of pleiotrophin, a growth and differentiation factor that is active in various pathophysiologic processes, including angiogenesis, has been associated with osteoarthritic changes of human articular cartilage. The association between pleiotrophin expression and pathologic conditions of the human intervertebral disc is unknown.Methods. Specimens of human lumbar intervertebral discs, obtained following surgical discectomy, were divided into 3 groups: nondegenerated discs (n = 7), degenerated discs (n = 6), and prolapsed discs (n = 11). Serial tissue sections of each specimen were immunostained to determine the presence of pleiotrophin, blood vessels (CD34-positive endothelial cells), and nerves (neurofilament 200 kDa [NF200]-positive nerve fibers).Results. Pleiotrophin immunoreactivity was seen in disc cells, endothelial cells, and in the extracellular matrix in most specimens of intervertebral disc but was most prevalent in vascularized tissue in prolapsed discs. There was a significant correlation between the presence of pleiotrophin-positive disc cells and that of CD34-positive blood vessels. NF200-positive nerves were seen in vascularized areas of more degenerated discs, but nerves did not appear to codistribute with blood vessels or pleiotrophin positivity in prolapsed discs.Conclusions. Pleiotrophin is present in pathologic human intervertebral discs, and its prevalence and distribution suggest that it may play a role in neovascularization of diseased or damaged disc tissue.

Small and Medium-scale Enterprises (SMEs), which generate more than one half of the employment (58.9%) and turnover (51.9%), form an important sector of the UK economy. Although they are the main drivers of the UK economy, they are also said to be the most vulnerable to the impacts of Extreme Weather Events (EWEs). The world in recent years has experienced a significant number of EWEs, and SMEs have suffered significant economic losses as a result. The now apparent climate change, which is mostly attributed to human interference with the environment over the past few decades, is believed to have a strong link with the increase of EWEs in the recent past. Threats of EWEs are expected to further increase due to their increased frequency and magnitude and increased vulnerability to their effects. Interestingly, EWEs seem to present businesses with various business opportunities and positive consequences as well, besides the much feared and overwhelming threats and negative consequences they present. Understanding such impacts has become a necessity to improve the resilience of SMEs so that they will be better prepared to minimise the negative consequences and maximise the positive consequences posed by EWEs. This paper attempts to bring together and evaluate the current knowledge with regard to the effects of EWEs on SMEs. The paper establishes the case for more in-depth study with this regard and concludes by stressing the need for improving the resilience of SMEs to EWEs.

To achieve the Shannon Capacity Limit, we need to develop practical, effective and deployable non-linear devices to invert the non-linear effects of the transmission line. In this work, we will summarise the progress we are making to realise these, specifically looking at optical phase conjugation and phase regenerators as methods to improve non-linear tolerances. © 2014 IEEE.

This paper draws on ethnographic research carried out in Birmingham, UK – a city significant for its sizeable Muslim population and its iconic role in the history of minority ethnic settlement in Britain – to consider how associations of place and ethnicity work in different ways to inform ideas about ‘Muslim community’ in twenty-first-century Britain. The paper charts happenings around a local event in an area of majority Asian settlement and how representations of the area as a place of Muslim community were used to implicate it in the ‘war on terror’. The paper goes on to show how this sensibility is disrupted by Muslims themselves through alternative engagements with space and ethnicity. The paper argues that these offer a ground for making Muslim community in ways that actively engage with histories and patterns of ethnic settlement in the city rather than being determined by them.
