Negotiating hegemonic masculinity: imaginary positions and psycho-discursive practices
In this paper we provide a critical analysis of the concept of hegemonic masculinity. We argue that although this concept embodies important theoretical insights, it is insufficiently developed as it stands to enable us to understand how men position themselves as gendered beings. In particular it offers a vague and imprecise account of the social psychological reproduction of male identities. We outline an alternative critical discursive psychology of masculinity. Drawing on data from interviews with a sample of men from a range of ages and from diverse occupational backgrounds, we delineate three distinctive, yet related, procedures or psycho-discursive practices, through which men construct themselves as masculine. The political implications of these discursive practices, as well as the broader implications of treating the psychological process of identification as form of discursive accomplishment, are also discussed
Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
The prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
The multitasking framework: the effects of increasing workload on acute psychobiological stress reactivity
A variety of techniques exist for eliciting acute psychological stress in the laboratory; however, they vary in terms of their ease of use, reliability to elicit consistent responses and the extent to which they represent the stressors encountered in everyday life. There is, therefore, a need to develop simple laboratory techniques that reliably elicit psychobiological stress reactivity that are representative of the types of stressors encountered in everyday life. The multitasking framework is a performance-based, cognitively demanding stressor, representative of environments where individuals are required to attend and respond to several different stimuli simultaneously with varying levels of workload. Psychological (mood and perceived workload) and physiological (heart rate and blood pressure) stress reactivity was observed in response to a 15-min period of multitasking at different levels of workload intensity in a sample of 20 healthy participants. Multitasking stress elicited increases in heart rate and blood pressure, and increased workload intensity elicited dose–response increases in levels of perceived workload and mood. As individuals rarely attend to single tasks in real life, the multitasking framework provides an alternative technique for modelling acute stress and workload in the laboratory

Constructing Subjects, Producing Subjectivities: Developing Analytic Needs in Discursive Psychology
The publication of Potter and Wetherell’s (1987) blueprint for a discursive
social psychology was a pivotal moment in the discursive turn in psychology.
That transformational text went on to underpin much contemporary discursive
psychology; paving the way for what has become an enriching range of
analytic approaches, and epistemological and ontological arguments
(Wetherell, Taylor and Yates, 2001a; 2001b). Twenty years on, and as
discursive psychology continues to develop, the approaches it encompasses are
becoming more vibrantly contested and a range of positions are forming
around what one might appropriately designate a discursive psychology, and
what form that discursive psychology should take (Wetherell, forthcoming,
2007).
In this exploratory paper I pursue some of these debates insofar as they
offer analytic resources for my PhD study of women’s accounts of success and
failure. I outline two different strands in discursive psychology; an
epistemological constructionism concerned with how meaning is established in
interaction; and an ontological constructionism, which takes this somewhat
further by looking at the implications of constructions for subjects and
subjectivity. I consider a range of resources available for a discursive
psychology attentive to the everyday practices of lived lives, to the
intersubjective production of meanings and to the theorisation of individual
history and individual differences. As part of this, I explore the potential
contribution of a psycho-social discursive psychology, significant for the
inextricable connection it makes between individual and society, and for how it
might inform notions of a dynamic, acting, individual. In this, however, I query
whether a discursive psycho-social psychology must necessarily draw upon
traditional psychoanalytic architectures

Aesop in Verse
The introduction finds verse appealing for children and even adults and offers the combined authority of Socrates, Phaedrus, and La Fontaine in favor of fables in poetry. At any rate, among the countless current editions of the Fables one edition in verse will not be regarded as quite out of place (ix). The morals are given in pentameter couplets, while the stories themselves are in couplets apparently of four feet and then three. The T of C on xiii-xvi numbers the one hundred fables here, and there is an AI at the back. A fable and its illustration take up either one or two pages. I read the first ten fables and enjoyed them and their illustrations. Wetherell is faithful to the tradition. The wolf's final retort to the lamb is nicely done: All your excuses but vex me the more,/And there's yet one way to treat you:/If I'm always wrong and you're always right,/I still can manage to eat you (3). Does it help MM to have the maid walking home rather than to market (4)? Poetry is a cruel mistress, and WC may show the compromises Wetherell needs to make to keep his rhyme and rhythm going (7). I am surprised that I have never heard or read of this book. May it not have been distributed outside Canada? Not in Bodemann.

A possible mechanism of superconductivity in high-T-c cuprates
This paper derives a generic T-c formula by using the long-range phase coherence condition in quantum phase fluctuation of the order parameter. Taking the two-local-spin-mediated interaction (TLSMI) proposed by Liu and Chen [Phys. Rev. B 58 (1998) 8812] as a Cooper pair potential, and the T-c formula, this paper explains five basic experimental facts in high-T-c cuprates. The aim of this paper is to show that TLSMI is a possible pairing mechanism of superconductivity in high-T-c cuprates. (C) 2000 Elsevier Science B.V.

DNA fusion gene vaccination mobilizes effective anti-leukemic cytotoxic T lymphocytes from a tolerized repertoire
The majority of known human tumor-associated antigens derive from non-mutated self proteins. T cell tolerance, essential to prevent autoimmunity, must therefore be cautiously circumvented to generate cytotoxic T cell responses against these targets. Our strategy uses DNA fusion vaccines to activate high levels of peptide-specific CTL. Key foreign sequences from tetanus toxin activate tolerance-breaking CD4+ T cell help. Candidate MHC class Ibinding tumor peptide sequences are fused to the C terminus for optimal processing and presentation. To model performance against a leukemia-associated antigen in a tolerized setting, we constructed a fusion vaccine encoding an immunodominant CTL epitopederived from Friend murine leukemia virus gag protein (FMuLVgag) and vaccinated tolerant FMuLVgag-transgenic (gag-Tg) mice. Vaccination with the construct induced epitopespecificIFN-c-producing CD8+ T cells in normal and gag-Tg mice. The frequency and avidity of activated cells were reduced in gag-Tg mice, and no autoimmune injury resulted. However, these CD8+ T cells did exhibit gag-specific cytotoxicity in vitro and in vivo. Also, epitope-specific CTL killed FBL-3 leukemia cells expressing endogenous FMuLVgag antigen and protected against leukemia challenge in vivo. These results demonstrate a simple strategy to engage anti-microbial T cell help to activate epitope-specific polyclonal CD8+ T cell responses from a residual tolerized repertoire
