Taking a stand: using psychoanalysis to explore the positioning of subjects in discourse

This paper is concerned with thinking through the cultural construction of personal identities whilst avoiding the classical social–individual division. Our starting point is the notion that there is no such thing as ‘the individual’, standing outside the social; however, there is an arena of personal subjectivity, even though this does not exist other than as already inscribed in the sociocultural domain. Our argument is that there are psychoanalytic concepts which can be helpful in exploring this ‘inscription’ and thus in explaining the trajectory of individual subjects; that is, their specific positioning in discourse. The argument is illustrated by data from a qualitative study of young masculinities, exploring the ways in which some individual boys take up positions in various degrees of opposition to the dominant ideology of ‘hegemonic’ masculinity

Re-interpreting: Narratives of childhood language brokering over time

This article probes how childhood experiences are actively taken into adult lives and thus challenges the unwitting and unintentional reproduction of an adult–child binary in childhood studies. We do this by analyzing interviews with one adult daughter of immigrants from Mexico to the United States at four points in time (ages 19, 26, 27, and 33). Using narrative analysis to examine the mutability of memory, we consider how Eva oriented herself to her childhood story, what was salient and invisible in each recount, the values she associated with the practice, and the meanings she took from her experiences. We show how Eva re-interpreted her experiences as an immigrant child language broker in relation to unfolding life events, showing her childhood to be very much alive in her adult life. Language brokering serves as one way in which to examine the interpenetration of childhood into adulthood, rather than being the focus per se

Survey Instrument for Gender Based Violence

This is a proposal for the design of a survey on gender-based violence across Europe. It introduces the purpose of the survey, which shapes the priorities embedded in the proposed design. It identifies the major issues involved in operationalising the concept of gender-based violence for a survey. It identifies some technical issues and how they are best addressed. The focus is on the questionnaire, largely leaving to one side the design of the survey and its strategy for issues such as sampling. This proposal draws on experience of a wide range of surveys and draws on selected parts of the architecture and questionnaire of the Crime Survey for England and Wales (CSEW), modified to fit the present priorities

Young mothers in care, contributing to the contemporary debate

Teenage pregnancy has become a broad issue in contemporary society and has become a focus for concern for young women in or exiting the care system. The article draws on interviews with twenty-four young mothers in, or on the fringes of the care system. It highlights the thoughts and feelings of these young women, specifically looking at the relationships that they have with their mothers, the father of their baby and their social workers. The mothers' sources of support and their perceptions of these are discussed. Implications for practice for working with this discrete group of young mothers are explored

Low pH enhances the action of maximin H5 against Staphylococcus aureus and helps mediate lysylated phosphatidylglycerol induced resistance

Maximin H5 (MH5) is an amphibian antimicrobial peptide specifically targeting Staphylococcus aureus. At pH 6, the peptide showed an increased ability to penetrate (∆П = 6.2 mN m-1) and lyse (lysis = 48 %) S. aureus membrane mimics, which incorporated physiological levels of lysylated phosphatidylglycerol (Lys-PG, 60 %) as compared to pH 7 (∆П = 5.6 mN m-1 and lysis = 40 % at pH 7) where levels of Lys-PG are lower (40 %). The peptide therefore appears to have optimal function at pH levels known to be optimal for the organism’s growth. MH5 killed S. aureus (minimum inhibitory concentration = 90 µM) via membranolytic mechanisms that involved the stabilization of α-helical structure (circa 45-50 %) and which showed similarities to the ‘Carpet’ mechanism based on its ability to increase the rigidity (Cs-1 = 109.94 mN m-1) and thermodynamic stability (∆Gmix = -3.0) of physiologically relevant S. aureus membrane mimics at pH 6. Based on theoretical analysis this mechanism may involve the use of a tilted peptide structure and efficacy was noted to vary inversely with the Lys-PG content of S. aureus membrane mimics for each pH studied (R2 circa 0.97), which led to the suggestion that under biologically relevant conditions, low pH helps mediate Lys-PG induced resistance in S. aureus to MH5 antibacterial action. The peptide showed a lack of haemolytic activity (< 2 % haemolysis) and merits further investigation as a potential template for development as an anti-staphylococcal agent in medically and biotechnically relevant areas

Security against eavesdropping in quantum cryptography

In this article we deal with the security of the BB84 quantum cryptography protocol over noisy channels using generalized privacy amplification. For this we estimate the fraction of bits needed to be discarded during the privacy amplification step. This estimate is given for two scenarios, both of which assume the eavesdropper to access each of the signals independently and take error correction into account. One scenario does not allow a delay of the eavesdropper's measurement of a measurement probe until he receives additional classical information. In this scenario we achieve a sharp bound. The other scenario allows a measurement delay, so that the general attack of an eavesdropper on individual signals is covered. This bound is not sharp but allows a practical implementation of the protocol.Comment: 11 pages including 3 figures, contains new results not contained in my Phys. Rev. A pape

Narratives of success among Irish and African Caribbean migrants

This paper compares the narratives of two men in midlife who migrated to the UK from Ireland and from the Caribbean as children, in the middle of the last century. We examine how success is narrated over the life course to show how migrants’ positioning of themselves differs from the ways in which they are positioned by outsiders, including in policy and public discourse. We conclude that while outsider narratives often polarise success and failure, insider understandings of success are dynamic and culturally and historically situated

Testing Bell's inequality with two-level atoms via population spectroscopy

We propose a feasible experimental scheme, employing methods of population spectroscopy with two-level atoms, for a test of Bell's inequality for massive particles. The correlation function measured in this scheme is the joint atomic $Q$ function. An inequality imposed by local realism is violated by any entangled state of a pair of atoms.Comment: 4 pages, REVTeX, no figures. More info on http://www.ligo.caltech.edu/~cbrif/science.htm
