This paper undertakes a content analysis of the discourse on the Open Method of Coordination on Health Care (OMC/HC) in order to show how equity and solidarity are increasingly linked to optimisation and, as such, how neoliberalism increasingly frames health care. Some of the side-effects of this reframing for politics are highlighted: legitimating and extending EU governance, reducing the space for oppositional formations and limited citizenship. The analysis begins by interrogating the broader context of the Lisbon Strategy II, after which the techniques of the OMC/HC and its substantive outputs are analysed.

This article argues that the early development of crime writing needs to be understood in relation to the consolidation of the modern state. It demonstrates that London in the 1720s constitutes a significant moment in this early development for three main reasons. First, the period witnessed a crime epidemic which reached its climax in the 1720s and which precipitated a set of particularly aggressive counter-measures by the state; second, it saw the rise and eventual fall of the infamous Jonathan Wild who acted as both thief and surrogate policeman; and third, it was also marked by a surge in interests on the part of writers like Daniel Defoe and Bernard Mandeville in the related matters of crime and punishment. This article explores the ways in which accounts of crime and punishment in this period deployed and in some instances interrogated the rhetoric of social contract theory and writings on statecraft, particularly by Thomas Hobbes and Mandeville. But while the criminal biographies and gallows sermons produced by the Newgate prison’s ‘ordinaries’ provided crude and reductive accounts of the efficacy of the state, the article shows how two accounts of the life of Jonathan Wild (by Defoe and H.D) responded in highly complex ways to the issues of crime and policing and provided a consistently and self-consciously ambivalent reading of the state and state power. To conclude, I suggest that this ambivalence can be read as a critique of the impartial or neutral state and that it constitutes one of the key features of what we would later understand to be crime writing as a dedicated literary genre.

Since its emergence as a discipline in the 1960s, women’s history has had a profound effect on the study of the past. Scholarship on women’s experiences of and contributions to the Russian revolutionary movement has increased exponentially since the publication of a number of biographies of Aleksandra Kollontai in the 1970s and 1980s and a comprehensive picture has emerged of women’s involvement in all the major revolutionary parties, as leading figures as well as rank and file activists. Despite this wealth of historical discovery, remarkably little has found its way into so-called ‘general’ histories of the revolution. An integrated history, which is the ultimate aim of women’s history, has yet to be produced for the Russian revolutionary movement, even though recent prosopographical studies of revolutionary women have made clear the numerous ways in which men and women cooperated and interacted on a daily basis in the underground. This article explores the nature of and reasons for this failure, makes a case for why incorporating women’s experiences into the grand narrative of the Russian revolution is important and discusses how this might be achieved.

This article discusses the identification of nonlinear dynamic systems using multi-layer perceptrons (MLPs). It focuses on both structure uncertainty and parameter uncertainty, which have been widely explored in the literature of nonlinear system identification. The main contribution is that an integrated analytic framework is proposed for automated neural network structure selection, parameter identification and hysteresis network switching with guaranteed neural identification performance. First, an automated network structure selection procedure is proposed within a fixed time interval for a given network construction criterion. Then, the network parameter updating algorithm is proposed with guaranteed bounded identification error. To cope with structure uncertainty, a hysteresis strategy is proposed to enable neural identifier switching with guaranteed network performance along the switching process. Both theoretic analysis and a simulation example show the efficacy of the proposed method.

AIM: To understand the uniqueness of the experience of testing HIV positive from the perspective of pregnant women.
BACKGROUND: As more people learn of their HIV diagnosis through routine screening processes, it is timely to reflect on the impact of receiving an unexpected positive result.
DESIGN: A prospective qualitative study.
METHODS: This paper draws on the case studies of four women who were participating in a larger prospective qualitative study of reproductive decision-making, pregnancy and childbirth following HIV diagnosis. Multiple interviews were conducted following diagnosis during pregnancy, and, after the birth of their babies. Thematic data analysis was undertaken.
RESULTS: Drawing on Becker's theory of disruption, we document the 'sudden disjuncture' of their antenatal diagnosis and the embodied emotional struggle the women engaged in to create continuity in their lives. A diagnosis of HIV disrupted the women's biographies in terms of their health, relationships and social identity. As pregnant women, the threat of HIV was experienced most significantly in relation to their unborn child. However, their narratives also revealed how a diagnosis of HIV in the context of pregnancy, whilst traumatic, provided a focus for regaining continuity in their lives, as the baby became a metaphor for hope and orientation toward the future.
CONCLUSIONS: As HIV testing becomes more 'routine', the findings of this study serve to remind health professionals that a positive diagnosis continues to constitute a major trauma to individuals and families.
RELEVANCE TO CLINICAL PRACTICE: We propose that appropriately educated nursing and midwifery staff could facilitate the 'meaning making' process that is required for newly diagnosed HIV positive persons to find a subjective sense of well-being in their lives.

This paper examines a select number of poems by Middle Generation poets John Berryman and Anne Sexton in relation to questions of death, silence and the task that literature sets itself as understood in key works by Blanchot, Heidegger, and Levinas. Rather than recourse to the overtrodden critical path of confessional interpretations of their work, this paper connects Berryman’s The Dream Songs (1969) and two Sexton poems (‘Oh’ and ‘The Silence’) to the philosophical determinations of what it is language can say and what demands literature makes of the writer prepared to risk their own being in answer to its call. Central issues such as suicide and the originating silence of the work of art are intricately interwoven with Berryman’s and Sexton’s work. Leaving aside their biographies, and by approaching suicide as a philosophical problem with which their poetry wrestles, a restructured approach to their work becomes available. The impulse to suicide and the mental processes involved in considering and committing the act are instincts and responses located within an individual’s own psychology. For these writers particularly such issues are sited within a philosophical debate about language, what it can and cannot represent. If poetry articulates language’s argument about its own capability, it is the ideal forum for philosophical confrontations with the possibilities of existence as represented by the grave decision to take one’s own life. © The Author 2013.

We describe in this report the characterization of the recently discovered N-linked glycosylation locus of the human bacterial pathogen Campylobacter jejuni, the first such system found in a species from the domain Bacteria. We exploited the ability of this locus to function in Escherichia coli to demonstrate through mutational and structural analyses that variant glycan structures can be transferred onto protein indicating the relaxed specificity of the putative oligosaccharyltransferase PglB. Structural data derived from these variant glycans allowed us to infer the role of five individual glycosyltransferases in the biosynthesis of the N-linked heptasaccharide. Furthermore, we show that C. jejuni- and E. coli-derived pathways can interact in the biosynthesis of N-linked glycoproteins. In particular, the E. coli encoded WecA protein, a UDP-GlcNAc: undecaprenylphosphate GlcNAc-1-phosphate transferase involved in glycolipid biosynthesis, provides for an alternative N-linked heptasaccharide biosynthetic pathway bypassing the requirement for the C. jejuni-derived glycosyltransferase PglC. This is the first experimental evidence that biosynthesis of the N-linked glycan occurs on a lipid-linked precursor prior to transfer onto protein. These findings provide a framework for understanding the process of N-linked protein glycosylation in Bacteria and for devising strategies to exploit this system for glycoengineering.

The crystallization of hierarchical ZSM-5 in the presence of the organosilane octadecyl-dimethyl-(3-trimethoxysilyl-propyl)-ammonium chloride as the mesoporogen was investigated as a function of time and temperature. The synthesis by this method proceeds in two steps. The rapid formation of a predominantly amorphous disordered mesoporous aluminosilicate precursor phase is followed by the formation of globular highly mesoporous zeolite particles involving dissolution of the precursor phase. It is difficult to completely convert the initial phase into the final hierarchical zeolite. This limits the amount of aluminium built into the MFI network and the resulting Bronsted acidity. In the presence of iron, more crystalline hierarchical zeolite is obtained. These Fe-containing zeolites are excellent catalysts for the selective oxidation of benzene to phenol. Their hierarchical pore structure leads to higher reaction rates due to increased mass transfer and increased catalyst longevity despite more substantial coke formation. (C) 2011 Elsevier B.V.

IFN-ß, IL-27, and IL-10 have been shown to exert a range of similar immunoregulatory effects in murine and human experimental systems, particularly in Th1- and Th17-mediated models of autoimmune inflammatory disease. In this study we sought to translate some of our previous findings in murine systems to human in vitro models and delineate the interdependence of these different cytokines in their immunoregulatory effects. We demonstrate that human IL-27 upregulates IL-10 in T cell-activated PBMC cultures and that IFN-ß drives IL-27 production in activated monocytes. IFN-ß-driven IL-27 is responsible for the upregulation of IL-10, but not IL-17 suppression, by IFN-ß in human PBMCs. Surprisingly, IL-10 is not required for the suppression of IL-17 by either IL-27 or IFN-ß in this model or in de novo differentiating Th17 cells, nor is IL-27 signaling required for the suppression of experimental autoimmune encephalomyelitis (EAE) by IFN-ß in vivo. Furthermore, and even more surprisingly, IL-10 is not required for the suppression of Th17-biased EAE by IL-27, in sharp contrast to Th1-biased EAE. In conclusion, IFN-ß and IL-27 both induce human IL-10, both suppress human Th17 responses, and both suppress murine EAE. However, IL-27 signaling is not required for the therapeutic effect of IFN-ß in EAE. Suppression of Th17-biased EAE by IL-27 is IL-10-independent, in contrast to its mechanism of action in Th1-biased EAE. Taken together, these findings delineate a complex set of interdependent and independent immunoregulatory mechanisms of IFN-ß, IL-27, and IL-10 in human experimental models and in murine Th1- and Th17-driven autoimmunity.

This paper investigates adolescent men's pregnancy resolution choices in Australia, Ireland and Italy. It addresses two main gaps in the literature: the lack of research on (adolescent) men's views on unintended pregnancy and pregnancy resolution; and the lack of international comparative case studies on men and reproductive choices. Consistent with theories of the transformation of intimacies in society and the growth of individualization, the results suggest that adolescent men are interested in the effect of an unintended pregnancy on their individual biographies as well as the effect on their girlfriend's health and well-being. However, Australian male adolescents were much more likely to choose abortion than Italian or Irish adolescents, suggesting adolescent males have also internalized country level debates surrounding abortion. Methodologically, the paper demonstrates an innovative approach to data-collection using a computer-based interactive drama to facilitate participants' deliberation and responses. It was shown to engage a large number of adolescent men and is likely to have wider generalisability in developing international comparative research on the topic, as well as applications for health promotion.

Law and development, as both movement and practice, has led a tumultuous life: a hurried zenith cut short by a fatal critique followed by an opportunistic resurrection. The name alone is su?cient to trigger a range of reactions, extending from the complimentary to the condemnatory. In this article I track law and development’s evolution via an examination of its role in the remodelling of Egyptian society in the post-Nasser era. While the 2011 revolution has encouraged institutions such as USAID to hasten their legal reform e?orts, I argue that these are more akin to counter-revolution by ideology than genuine revolution by law. Nevertheless, rather than relegate the movement to the annals of imperial intrigue, I conclude by proposing the use of legal pluralism to revive, and possibly ignite, law and development’s emancipatory potential.
