    "I treat my daughters not like my mother treated me" : migrant and refugee women's constructions and experiences of menarche and menstruation

    Menstruation is a material reality at some point in most women’s lives. Yet, the discursive meaning assigned to menstruating bodies and the way in which they are experienced is dependent on the sociocultural and historical spaces which they occupy (Lee and Sasser-Coen 1996, 13). Across cultural contexts, menarche is constructed as a symbolic transition from childhood to womanhood, a period of growth and change, often linked with sexual maturation (Lee 2009, 622). While menstrual activists, artists, poets, and women’s rights organizations are challenging negative representations and practices surrounding menstruation (Bobel 2010, 42), dominant discourses often still portray menstruation as something dirty and disgusting, and a bodily function to be silenced and concealed (Brantelid, Nilvér, and Alehagen 2014, 606; Mason et al. 2013, 4; see also Wood [Chapter 25] in this volume)

    Sexuality and Intimacy in the Context of Cancer

    The impact of cancer on sexuality and intimacy: A key aspect of quality of life In 2006, more than 106,000 new cases of cancer were diagnosed in Australia, with the number of new cases in New South Wales alone expected to grow to 40,116 by 2011 (AIHW et al., 2007, Tracey et al., 2005). It is now widely recognised that cancer and its treatment can have a significant effect on the quality of life of both people with cancer (Stommel et al., 2004) and their family members, in particular their intimate partner (Hodges et al., 2005). Sexuality and intimacy are important aspects of an individual's quality of life (World Health Organisation, 1995), and there is a growing body of evidence to show that cancer can result in dramatic changes to sexuality, sexual functioning, relationships, and sense of self, regardless of cancer type. Indeed, these changes can be experienced as the most significant in the person with cancer's life (Anderson et al., 2000)

    Evolutionary dynamics of group interactions on structured populations: a review

    Get PDF
    Interactions among living organisms, from bacteria colonies to human societies, are inherently more complex than interactions among particles and non-living matter. Group interactions are a particularly important and widespread class, representative of which is the public goods game. In addition, methods of statistical physics have proved valuable for studying pattern formation, equilibrium selection and self-organization in evolution- ary games. Here, we review recent advances in the study of evolutionary dynamics of group interactions on top of structured populations, including lattices, complex networks and coevolutionary models. We also compare these results with those obtained on well-mixed populations. The review particularly highlights that the study of the dynamics of group interactions, like several other important equilibrium and non-equilibrium dynamical processes in biological, economical and social sciences, benefits from the synergy between statistical physics, network science and evolutionary game theory

    Black holes and black strings of N=2, d=5 supergravity in the H-FGK formalism

    Get PDF
    We study general classes and properties of extremal and non-extremal static black-hole solutions of N=2, d=5 supergravity coupled to vector multiplets using the recently proposed H-FGK formalism, which we also extend to static black strings. We explain how to determine the integration constants and physical parameters of the black-hole and black-string solutions. We derive some model-independent statements, including the transformation of non-extremal flow equations to the form of those for the extremal flow. We apply our methods to the construction of example solutions (among others a new extremal string solution of heterotic string theory on K_3 \times S^1). In the cases where we have calculated it explicitly, the product of areas of the inner and outer horizon of a non-extremal solution coincides with the square of the moduli-independent area of the horizon of the extremal solution with the same charges.Comment: 33 pages.

    Special Geometry of Euclidean Supersymmetry III: the local r-map, instantons and black holes

    Full text link
    We define and study projective special para-Kahler manifolds and show that they appear as target manifolds when reducing five-dimensional vector multiplets coupled to supergravity with respect to time. The dimensional reductions with respect to time and space are carried out in a uniform way using an epsilon-complex notation. We explain the relation of our formalism to other formalisms of special geometry used in the literature. In the second part of the paper we investigate instanton solutions and their dimensional lifting to black holes. We show that the instanton action, which can be defined after dualising axions into tensor fields, agrees with the ADM mass of the corresponding black hole. The relation between actions via Wick rotation, Hodge dualisation and analytic continuation of axions is discussed.Comment: 72 pages, 2 figure

    Non-supersymmetric extremal multicenter black holes with superpotentials

    Full text link
    Using the superpotential approach we generalize Denef's method of deriving and solving first-order equations describing multicenter extremal black holes in four-dimensional N = 2 supergravity to allow non-supersymmetric solutions. We illustrate the general results with an explicit example of the stu model.Comment: 17 pages, v2: some clarifications adde

    Elastic Tensor of Sr2_2RuO4_4

    Full text link
    The six independent elastic constants of Sr2_2RuO4_4 were determined using resonant ultrasound spectroscopy on a high-quality single-crystal specimen. The constants are in excellent agreement with those obtained from pulse-echo experiments performed on a sample cut from the same ingot. A calculation of the Debye temperature using the measured constants agrees well with values obtained from both specific heat and M\"{o}ssbauer measurements.Comment: 4 pages, 2 figures, 2 tables, submitted to PR

    Brane solutions and integrability: a status report

    Full text link
    We review the status of the integrability and solvability of the geodesics equations of motion on symmetric coset spaces that appear as sigma models of supergravity theories when reduced over respectively the timelike and spacelike direction. Such geodesic curves describe respectively timelike and spacelike brane solutions. We emphasize the applications to black holes.Comment: 4 pages, Proceedings of ERE 2010, Granada, 6-10 september 201
