Promoting Civil Society Across the Borders of the EU Neighbourhood: Debates, Constraints and Opportunities

One of the aims of this article it to clarify the nature of the debate over 'civil society' and its relationship to the state. It begins by suggesting that the EU's borderland provides a context in which deep-rooted 'Western' and 'Eastern' understandings of state and civil society meet and overlap. The second section outlines the geo-political reshaping of the 'Neighbourhood'. It concentrates on the influence of non-EU actors, notably Russia, complementing the EU-focused literature on the subject. The third section elaborates the consensus in the literature on the weakness of civil society in the EU 'Neighbourhood'. This is followed by a discussion of 'Western' debates over the role and significance of civil society.

Photo-double detachment from the F- ion

The correlated process of photodetaching two electrons from the F- ion following the absorption of a single photon has been investigated over an energy range 20-62 eV. In the experiment, a beam of photons from the Advanced Light Source was collinearly merged with a counter-propagating beam of F- ions from a sputter ion source. The F+ ions produced in the interaction region were detected, and the normalized signal was used to monitor the relative cross section for the double-detachment reaction. An absolute scale for the cross section was established by measuring the spatial overlap of the two beams and by determining the efficiency for collection and detection of the F+ ions. The measured cross section is compared with R-matrix and random phase approximation calculations. These calculations show that the Auger decay of the 2s2p(6) core-excited state of the F atom plays a minor role in the production of F+ ions and that double detachment is likely to be dominated by simultaneous correlated ejection of two valence electrons at energies well above threshold.

Regarding the Real: Cinema, Documentary, and the Visual Arts

Regarding the Real: Cinema, Documentary, and the Visual Arts develops an interdisciplinary approach to documentary film, focusing on its cultural and formal relations to other visual arts, such as animation, assemblage, photography, painting, sculpture, and architecture. The book considers the work of figures whose preferred film language is associative and fragmentary, and for whom the documentary is an endlessly open form, an unstable expressive phenomenon that cannot but interrogate the validity of its own narratives and representational modes. Combining close analysis with cultural history, Regarding the Real calls for a re-assessment of the influence of the modern arts in subverting the structures of realism typically associated with documentary filmmaking.

‘Government(ality) By Experts: Human Rights as Governance’

The suggestion that the general economy of power in our societies is becoming a domain of security was made by Michel Foucault in the late 1970s. This paper takes inspiration from Foucault?s work to interpret human rights as technologies of governmentality, which make possible the safe and secure society. I examine, by way of illustration, the site of the European Union and its use of new modes of governance to regulate rights discourse – in particular via the emergence of a new Fundamental Rights Agency. „Governance? in the EU is constructed in an apolitical way, as a departure from traditional legal and juridical methods of governing. I argue, however, that the features of governance represent technologies of government(ality), a new form of both being governed through rights and of governing rights. The governance feature that this article is most interested in is experts. The article aims to show, first and foremost, how rights operate as technologies of governmentality via a new relation to expertise. Second, it considers the significant implications that this reading of rights has for rights as a regulatory and normalising discourse. Finally, it highlights how the overlap between rights and governance discourses can be problematic because (as the EU model illustrates) governance conceals the power relations of governmentality, allowing, for instance, the unproblematic representation of the EU as an international human rights actor

Plasmonic nanorod metamaterials for biosensing.

Label-free plasmonic biosensors rely either on surface plasmon polaritons or on localized surface plasmons on continuous or nanostructured noble-metal surfaces to detect molecular-binding events(1-4). Despite undisputed advantages, including spectral tunability(3), strong enhancement of the local electric field(5,6) and much better adaptability to modern nanobiotechnology architectures(7), localized plasmons demonstrate orders of magnitude lower sensitivity compared with their guided counterparts(3). Here, we demonstrate an improvement in biosensing technology using a plasmonic metamaterial that is capable of supporting a guided mode in a porous nanorod layer. Benefiting from a substantial overlap between the probing field and the active biological substance incorporated between the nanorods and a strong plasmon-mediated energy confinement inside the layer, this metamaterial provides an enhanced sensitivity to refractive-index variations of the medium between the rods (more than 30,000nm per refractive-index unit). We demonstrate the feasibility of our approach using a standard streptavidin-biotin affinity model and record considerable improvement in the detection limit of small analytes compared with conventional label-free plasmonic devices.

Eigenvalues of the time-delay matrix in overlapping resonances

We discuss the properties of the lifetime or the time-delay matrix Q(E) for multichannel scattering, which is related to the scattering matrix S(E) by Q = i?S(dS†/dE). For two overlapping resonances occurring at energies E with widths G(? = 1, 2), with an energy-independent background, only two eigenvalues of Q(E) are proved to be different from zero and to show typical avoided-crossing behaviour. These eigenvalues are expressible in terms of the four resonance parameters (E , G) and a parameter representing the strength of the interaction of the resonances. An example of the strong and weak interaction in an overlapping double resonance is presented for the positronium negative ion. When more than two resonances overlap (? = 1, ..., N), no simple representation of each eigenvalue has been found. However, the formula for the trace of the Q-matrix leads to the expression d(E) = -?arctan[(G/2)/(E - E)] + d(E) for the eigenphase sum d(E) and the background eigenphase sum d(E), in agreement with the known form of the state density. The formulae presented in this paper are useful in a parameter fitting of overlapping resonances. © 2006 IOP Publishing Ltd.

PIM-1 kinase expression in adipocytic neoplasms: diagnostic and biological implications

The differential diagnosis of soft tissue tumours poses a considerable challenge for pathologists, especially adipocytic tumours, as these may show considerable overlap in clinical presentation and morphological features with many other mesenchymal neoplasms. Hence, a specific and reliable marker that identifies adipocytic differentiation is much sought. We investigated the immunohistochemical expression of PIM-1 kinase in 35 samples of soft tissue tumours using tissue microarray technology and 49 full sections of adipocytic (n = 26) and non-adipocytic tumours (n = 23). Benign and malignant adipocytic tumours showed strong expression of PIM-1 while the non-adipocytic tumours were either negative or showed only weak staining for the protein. In myxoid liposarcomas, PIM-1 showed a distinct, unique vacuolar staining pattern, clearly outlining fine cytoplasmic lipid vacuoles. By contrast, non-adipocytic myxoid tumours (myxoma, chordoma and myxoid chondrosarcoma) did not show this vacuolar pattern of PIM-1 staining, although vacuolated cells were present on H&E. This differential expression was confirmed at a gene expression level in selected cases. Our results indicate that the expression of PIM-1 in adipose tissue may be a useful marker of adipocytic differentiation, in particular if the staining is both of high intensity and present in a unique, vacuolar pattern.

Conventional 3D staging PET/CT in CT simulation for lung cancer: impact of rigid and deformable target volume alignments for radiotherapy treatment planning

Objective: Positron emission tomography (PET)/CT scans can improve target definition in radiotherapy for non-small cell lung cancer (NSCLC). As staging PET/CT scans are increasingly available, we evaluated different methods for co-registration of staging PET/CT data to radiotherapy simulation (RTP) scans.

Methods: 10 patients underwent staging PET/CT followed by RTP PET/CT. On both scans, gross tumour volumes (GTVs) were delineated using CT (GTVCT) and PET display settings. Four PET-based contours (manual delineation, two threshold methods and a source-to-background ratio method) were delineated. The CT component of the staging scan was co-registered using both rigid and deformable techniques to the CT component of RTP PET/CT. Subsequently rigid registration and deformation warps were used to transfer PET and CT contours from the staging scan to the RTP scan. Dice’s similarity coefficient (DSC) was used to assess the registration accuracy of staging-based GTVs following both registration methods with the GTVs delineated on the RTP PET/CT scan.

Results: When the GTVCT delineated on the staging scan after both rigid registration and deformation was compared with the GTVCT on the RTP scan, a significant improvement in overlap (registration) using deformation was observed (mean DSC 0.66 for rigid registration and 0.82 for deformable registration, p50.008). A similar comparison for PET contours revealed no significant improvement in overlap with the use of deformable registration.

Conclusions: No consistent improvements in similarity measures were observed when deformable registration was used for transferring PET-based contours from a staging PET/CT. This suggests that currently the use of rigid registration remains the most appropriate method for RTP in NSCLC.

Phenotypic and genotypic variations within a single bacteriophage species.

Background: Although horizontal gene transfer plays a pivotal role in bacteriophage evolution, many lytic phage genomes are clearly shaped by vertical evolution. We investigated the influence of minor genomic deletions and insertions on various phage-related phenotypic and serological properties. Findings. We collected ten different isolates of Pseudomonas aeruginosa bacteriophage KMV. All sequenced genomes (42-43 kb, long direct terminal repeats) are nearly identical, which intuitively implied strongly similar infections cycles. However, their latent periods vary between 21 and 28 minutes and they are able to lyse between 5 and 58% of a collection of 107 clinical P. aeruginosa strains. We also noted that phages with identical tail structures displayed profound differences in host spectra. Moreover, point mutations in tail and spike proteins were sufficient to evade neutralization by two phage-specific antisera, isolated from rabbits. Conclusion: Although all analyzed phages are 83-97% identical at the genome level, they display a surprisingly large variation in various phenotypic properties. The small overlap in host spectrum and their ability to readily escape immune defences against a nearly identical phage are promising elements for the application of these phages in phage therapy. © 2011 Ceyssens et al; licensee BioMed Central Ltd.

‘Marxism and Ecology: From Political Economy to Political Ecology’

One of the reasons for the 'fin de seicle' angst within western liberal capitalist societies is the rise in prominance of ecological concerns within these societies. Long before the New Right declared the post-war welfare state to be untenable, early green critics had claimed it to be ecologically unsustainable. The addiction of the welfare state on ever increasing levels of economic growth was pronounced to be simply impossible within the context of a finite planet. Although it was not expressed in this manner, what these early ecological concerns with Limits to Growth were in effect saying was that the accumulation of capital rendered capitalism unsustainable. Yet the ecological critique of capitalism has not found much favour within the Marxist critique untile recently. Early Marxist analyses of the ecology movement dismissed them as ‘petty bourgeios radicals’ while many greens still view Marxism as ‘fair shares in extinction’. The lack of positive engagement and dialogue between Marxism and ecology has in recent years been put right with a discernable overlap between the two critiques of capitalism. This article seeks to present the areas of disagreement and agreement between the two and seeks to provide an ‘environmental audit’ on both the Marxist method and political project.

Civic Republicanism and Green Political Theory

Republicanism and in particular the civic republican tradition is not often one that one finds in discusions and debates within green political theory. It is interesting to note the relative lack of engagement between republican political theory and green political theory, unlike for example the research one can find on the relationship between green politics/political theory and liberalism, socialism and feminism. This is remarkable, given, as I hope to establish in this paper, the large areas of overlap between both, and in particular the compatibility of republican ideas and positions with key priciples and objectives of green theory, paricularly in relation to active citizenship, the centrality of recognising vulnerability and a commitment to liberty (as non-domination) and pluralism as key components of the transition to a more sustainable society.

Further observations on tentacular feeding mechanisms in holothurians

Resource partitioning by aspidochirote holothurians from Beacon Island, Western Australia is largely on the basis of distinct macro- and micro-habitat preferences. Where two or more species occur together or overlap, food partitioning may be by using distinct feeding techniques (Holothuria cinerascens (Brandt), H. impatiens (Forskal) and H. difficilis Semper) or by particle selectivity (H. cf. pervicax Selenka and H. hartmeyeri Erwe). Methods of particle handling by the majority of species studied are similar, involving the use of tentacular nodules on sediment deposits but H. cinerascens collects particles from suspension in a dendrochirote-like tentacle. The nature and rôle of surface secretions are considered for both types of tentacles and the taxonomic value of tentacle form in the Holothurioidea questioned.

Norms of Intentionality: Norms that Don't Guide

More than ever, it is in vogue to argue that no norms either play a role in or directly follow from the theory of mental content. In this paper, I present an intuitive theory of intentionality (including a theory of mental content) on which norms are constitutive of the intentional properties of attitude and content in order to show that this trend is misguided. Although this theory of intentionality—the teleological theory of intentional representation—does involve a commitment to representational norms, these norms are not problematic in the way critics have suggested they would be. In particular, these norms do not guide thinking by motivating intentional agents to (intentionally) accord with them; as a result, no obvious vicious regress threatens the theory. In the final section of this paper, I argue that accepting this teleological theory of intentionality need not commit one to thinking that intentionality is the product of natural selection.

Macroecological patterns and niche structure in a new marine food web

The integration of detailed information on feeding interactions with measures of abundance and body mass of individuals provides a powerful platform for understanding ecosystem organisation. Metabolism and, by proxy, body mass constrain the flux, turnover and storage of energy and biomass in food webs. Here, we present the first food web data for Lough Hyne, a species rich Irish Sea Lough. Through the application of individual-and size-based analysis of the abundance-body mass relationship, we tested predictions derived from the metabolic theory of ecology. We found that individual body mass constrained the flux of biomass and determined its distribution within the food web. Body mass was also an important determinant of diet width and niche overlap, and predator diets were nested hierarchically, such that diet width increased with body mass. We applied a novel measure of predator-prey biomass flux which revealed that most interactions in Lough Hyne were weak, whereas only a few were strong. Further, the patterning of interaction strength between prey sharing a common predator revealed that strong interactions were nearly always coupled with weak interactions. Our findings illustrate that important insights into the organisation, structure and stability of ecosystems can be achieved through the theoretical exploration of detailed empirical data.

A voxel based morphometry study investigating brain structural changes in first episode psychosis.

Schizophrenia (SCZ) and bipolar disorder (BP) are associated with neuropathological brain changes, which are believed to disrupt connectivity between brain processes and may have common properties. Patients at first psychotic episode are unique, as one can assess brain alterations at illness inception, when many confounders are reduced or absent. SCZ (N=25) and BP (N=24) patients were recruited in a regional first episode psychosis MRI study. VBM methods were used to study gray matter (GM) and white matter (WM) differences between patient groups and case by case matched controls. For both groups, deficits identified are more discrete than those typically reported in later stages of illness. SCZ patients showed some evidence of GM loss in cortical areas but most notable were in limbic structures such as hippocampus, thalamus and striatum and cerebellum. Consistent with disturbed neural connectivity WM alterations were also observed in limbic structures, the corpus callosum and many subgyral and sublobar regions in the parietal, temporal and frontal lobes. BP patients displayed less evidence of volume changes overall, compared to normal healthy participants, but those changes observed were primarily in WM areas which overlapped with regions identified in SCZ, including thalamus and cerebellum and subgyral and sublobar sites. At first episode of psychosis there is evidence of a neuroanatomical overlap between SCZ and BP with respect to brain structural changes, consistent with disturbed neural connectivity. There are also important differences however in that SCZ displays more extensive structural alteration.
