    Subliminally Perceived Odours Modulate Female Intrasexual Competition: An Eye Movement Study

    Background: Evidence suggests that subliminal odorants influence human perception and behavior. It has been hypothesized that the human sex-steroid derived compound 4,16-androstadien-3-one (androstadienone) functions as a human chemosignal. The most intensively studied steroid compound, androstadienone is known to be biologically relevant since it seems to convey information about male mate quality to women. It is unclear if the effects of androstadienone are menstrual cycle related. Methodology/Principal Findings: In the first experiment, heterosexual women were exposed to androstadienone or a control compound and asked to view stimuli such as female faces, male faces and familiar objects while their eye movements were recorded. In the second experiment the same women were asked to rate the level of stimuli attractiveness following exposure to the study or control compound. The results indicated that women at high conception risk spent more time viewing the female than the male faces regardless of the compound administered. Women at a low conception risk exhibited a preference for female faces only following exposure to androstadienone. Conclusions/Significance: We contend that a woman’s level of fertility influences her evaluation of potential competitors (e.g., faces of other women) during times critical for reproduction. Subliminally perceived odorants, such as androstadienone, might similarly enhance intrasexual competition strategies in women during fertility phases not critica

    Dijet production in √s = 7 TeV pp collisions with large rapidity gaps at the ATLAS experiment

    A 6.8 nb−¹ sample of pp collision data collected under low-luminosity conditions at √s = 7 TeV by the ATLAS detector at the Large Hadron Collider is used to study diffractive dijet production. Events containing at least two jets with pT > 20 GeV are selected and analysed in terms of variables which discriminate between diffractive and non-diffractive processes. Cross sections are measured differentially in ΔηF, the size of the observable forward region of pseudorapidity which is devoid of hadronic activity, and in an estimator, ξ˜, of the fractional momentum loss of the proton assuming single diffractive dissociation (pp → p X). Model comparisons indicate a dominant non-diffractive contribution up to moderately large ηF and small ξ˜, with a diffractive contribution which is significant at the highest ΔηF and the lowest ξ˜. The rapidity-gap survival probability is estimated from comparisons of the data in this latter region with predictions based on diffractive parton distribution functions

    The James Webb Space Telescope Mission

    Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least 4m4m. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the 6.5m6.5m James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

    Violence, identity and policing: the case of violence against transgender people

    No full text
    Book synopsis: The call by transgender people for the police to take violence against them more seriously has some familiar attributes. In general it is a violence characterized as hate crime. Transgender activism has highlighted many problems, for example, under-reporting, lack of trust and confidence in policing, lack of police recognition, low detection rates, clear up rates and infrequent judicial determinations of guilt. This activism might be characterized as another instance of identity politics emerging within the field of policing and criminal justice. While we welcome its emergence some scholars have been critical of the impact of identity politics upon policing and criminal justice bodies, suggesting it promotes further social and community divisions. Although we share some of these concerns, in this article we argue that these problems are the effect of particular assumptions about the nature of identity. We offer an analysis of identity politics that seeks to challenge this position, as well as an analysis of empirical data of transgender experiences of violence and insecurity arising out of research undertaken in Sydney, Australia. Our analysis exposes the multiple and simultaneous operation of many different social and cultural divisions at work in the context of transgender identity. We explore the significance of this approach to identity for policing
