INTRODUCTION Breast reconstruction is routinely offered to women who undergo mastectomy for breast cancer. However, patient-reported outcomes are mixed. Child abuse has enduring effects on adults’ well-being and body image. As part of a study into damaging effects of abuse on adjustment to breast cancer, we examined: (i) whether women with history of abuse would be more likely than other women to opt for reconstruction; and (ii) whether mood problems in women opting for reconstruction can be explained by greater prevalence of abuse. PATIENTS AND METHODS We recruited 355 women within 2-4 days after surgery for primary breast cancer; 104 had mastectomy alone and 29 opted for reconstruction. Using standardised questionnaires, women self-reported emotional distress and recollections of childhood sexual abuse. Self-report of distress was repeated 12 months later. RESULTS Women who had reconstruction were younger than those who did not. Controlling for this, they reported greater prevalence of abuse and more distress than those having mastectomy alone. They were also more depressed postoperatively, and this effect remained significant after controlling for abuse. CONCLUSIONS One interpretation of these findings is that history of abuse influences women's decisions about responding to the threat of mastectomy, but it is premature to draw inferences for practice until the findings are replicated. If they are replicated, it will be important to recognise increased vulnerability of some patients who choose reconstruction. Studying the characteristics and needs of women who opt for immediate reconstruction and examining the implications for women's adjustment should be a priority for research.

This article examines advocacy of Catholic restorative justice for clerical child sexual abuse from the standpoint of feminist criminological critiques of the use of restorative mediation in sexual offence cases. In particular, it questions the Catholic invocation of grace and forgiveness of survivors of abuse in light of critical feminist concerns about the exploitation of emotions in restorative practices, especially in regard to sexual and other gender-based offences. In the context of sexual abuse, the Catholic appeal to grace has the potential for turning into an extraordinary demand made of victims not only to rehabilitate offenders and the church in the eyes of the community, but also to work towards the spiritual absolution of the abuser. This unique feature of Catholic-oriented restorative justice raises important concerns in terms of feminist critiques of the risk of abuses of power within mediation, and is also incompatible with orthodox restorative justice theory, which, although it advocates a ‘spiritual’ response to crime, is concerned foremost with the rights, needs and experiences of victims.

Aims: The aim was to examine whether specific skills required for cognitive behavioural therapy (CBT) could be taught using a computerised training paradigm with people who have intellectual disabilities (IDs). Training aimed to improve: a) ability to link pairs of situations and mediating beliefs to emotions, and b) ability to link pairs of situations and emotions to mediating beliefs. Method: Using a single-blind mixed experimental design, sixty-five participants with IDs were randomised to receive either computerised training or an attention-control condition. Cognitive mediation skills were assessed before and after training. Results: Participants who received training were significantly better at selecting appropriate emotions within situation beliefs pairs, controlling for baseline scores and IQ. Despite significant improvements in the ability of those who received training to correctly select intermediating beliefs for situation-feelings pairings, no between-group differences were observed at post-test. Conclusions: The findings indicated that computerised training led to a significant improvement in some aspects of cognitive mediation for people with IDs, but whether this has a positive effect upon outcome from therapy is yet to be established.

Public–private partnerships (PPPs) are new in Russia and represent project implementation in progress. The government is actively pursuing PPP deployment in sectors such as transportation and urban infrastructure, and at all levels including federal, regional and especially local. Despite the lack of pertinent laws and regulations, the PPP public policy quickly transforms into a policy paradigm that provides simplified concepts and solutions and intensifies partnership development. The article delineates an emerging model of Russia’s PPP policy paradigm, whose structure includes the shared understanding of the need for long-term collaboration between the public sector and business, a changing set of government responsibilities that imply an increasing private provision of public services, and new institutional capacities. This article critically appraises the principal dynamics that contribute to an emerging PPP policy paradigm, namely the broad government treatment of the meaning of a partnership and of a contractual PPP; a liberal PPP approval process that lacks clear guidelines and consistency across regions; excessive emphasis on positive PPP externalities and neglect of drawbacks; and unjustifiably extensive government financial support to PPPs. Whilst a paradigm appears to be useful specifically for the policy purpose of PPP expansion, it may also mask inefficiencies such as higher prices of public services and greater government risks.

The theory of evolution by sexual selection for sexual size dimorphism (SSD) postulates that SSD primarily reflects the adaptation of males and females to their different reproductive roles. For example, competition among males for access to females increases male body size because larger males are better able to maintain dominant status than smaller males. Larger dominant males sire most offspring while smaller subordinate males are unsuccessful, leading to skew in reproductive success. Therefore, species with male-biased SSD are predicted to have greater variance in male reproductive success than those in which both sexes are similar in size. We tested this prediction among the Pinnipedia, a mammalian group with a great variation in SSD. From a literature review, we identified genetic estimates of male reproductive success for 10 pinniped taxa (eight unique species and two subspecies of a ninth species) that range from seals with similarly sized males and females to species in which males are more than four times as large as females. We found no support for a positive relationship between variance in reproductive success and SSD among pinnipeds after excluding the elephant seals Mirounga leonina and Mirounga angustirostris, which we discuss as distinctive cases. Several explanations for these results are presented, including the revival of one of Darwin's original ideas. Darwin proposed that natural selection may explain SSD based on differences in energetic requirements between sexes and the potential for sexual niche segregation. Males may develop larger bodies to exploit resources that remain unavailable to females due to the energetic constraints imposed on female mammals by gestation and lactation. The importance of this alternative explanation remains to be tested.

On the twenty-third of May 2015, Ireland became the first country to legalise same-sex marriage by popular vote. This event reversed a large part, if not all, of Ireland’s reputation for a Catholic-led conservatism concerning sexual and gender identities. I argue in this article that we can see a parallel-in-miniature to this momentous shift in something of a reversal of children’s literature’s views in this respect too, and I will concentrate on exploring what is at stake in the ways that childhood, sexual and gender identities are constructed in some recent children’s literature criticism in the light of these shifts. My interest is to consider: what is the ever-burgeoning interest in the gay, queer, cross-dressing, transsexual or transgender child precisely about? I ask this question on the grounds of not assuming that this interest in these identities arises necessarily simply out of a self-evident, progressive, liberatory impulse, and, alongside this, I also do not assume that ‘identities’ are essential, self-organised traits awaiting revelation and liberation.

This paper explores the way risk is constructed in the stories gay men tell of their sexual experiences. It focuses on how tellers use such stories to portray themselves both as rational actors and as legitimate members of their social groups by reconstructing the ‘orderliness’ of sexual encounters. An analysis of a corpus of stories derived from a diary study of gay male sexual behaviour in Hong Kong using current theories of discourse analysis reveals how narrators organize their experiences along two primary vectors of engagement: a sequential vector along which the trajectory of the sexual encounter is presented as a chain of occurrences, each occurrence contingent upon previous ones and warranting subsequent ones, and a hierarchical vector along which processes perceived on longer timescales are portrayed as exerting pressure on the ways processes on shorter timescales unfold. Examining how men portray these vectors in their accounts of risk behaviour can help us better understand both the situatedness of risk behaviour and the ways it is linked to larger social practices, identity projects and community histories

This paper examines the concept of ‘culture’ and its relationship to HIV prevention. Culture is here seen as the interaction between human beings and the various ‘cultural tools’ they appropriate when taking action. Among these tools are ways of speaking which encode certain meanings, ideologies and social practices. When individuals take action with regard to AIDS, what they do is mediated through voices which they borrow strategically from their environ- ment. The textual tools that are available and the ways individuals adapt and combine them work to either limit or amplify their participation in HIV prevention. What are traditionally seen as ‘cultures’ or ‘sub-cultures’, or worse, ‘risk groups’, are, in this perspective, viewed as ‘communities of practice’, groups of individuals who share particular cultural tools and ways of using them. This conceptual framework is applied to recent discourses of homosexuality and AIDS prevention in China. An instance of ‘of� cial’ discourse in the form of an AIDS education pamphlet for ‘gays’ is analysed for the voices it contains and how these voices are strategically marshalled by the authors and mixed with other voices in ways which amplify participation in AIDS prevention for some and limit it for others. This ‘offical’ discourse is then compared to the discourse of homosexually active Chinese men recently interviewed in Beijing and Fuzhou to examine which of these of� cial voices and other voices they appropriate, and how they adapt these voices in responding to HIV.

BACKGROUND/AIMS: Estrogens are important effectors of reproduction and are critical for upregulating female reproductive behavior or lordosis in females. In addition to the importance of transcriptional regulation of genes by 17beta-estradiol-bound estrogen receptors (ER), extranuclear signal transduction cascades such as protein kinase A (PKA) are also important in regulating female sexual receptivity. GPR30 (G-protein coupled receptor 30), also known as GPER1, a putative membrane ER (mER), is a G protein-coupled receptor that binds 17beta-estradiol with an affinity that is similar to that possessed by the classical nuclear ER and activates both PKA and extracellular-regulated kinase signaling pathways. The high expression of GPR30 in the ventromedial hypothalamus, a region important for lordosis behavior as well as kinase cascades activated by this receptor, led us to hypothesize that GPR30 may regulate lordosis behavior in female rodents. METHOD: In this study, we investigated the ability of G-1, a selective agonist of GPR30, to regulate lordosis in the female mouse by administering this agent prior to progesterone in an estradiol-progesterone priming paradigm prior to testing with stud males. RESULTS: As expected, 17beta-estradiol benzoate (EB), but not sesame oil, increased lordosis behavior in female mice. G-1 also increased lordosis behavior in female mice and decreased the number of rejective responses towards male mice, similar to the effect of EB. The selective GPR30 antagonist G-15 blocked these effects. CONCLUSION: This study demonstrates that activation of the mER GPR30 stimulates social behavior in a rodent model in a manner similar to EB.

Individual fitness and the structure of marine communities are strongly affected by spatial competition. Among the most common space holders are the colonial ascidians, which have the ability to monopolize large areas of hard substrate, overgrowing most other competitors. The effects of competition on colony growth and on gonad production of the ascidian Didemnum perlucidum were studied in southeastern Brazil by experimentally removing surrounding competitors. Colonies of D, perlucidum competing for space exhibited a growth rate 9 times less than that of colonies that were competitor free. Among the colonies subject to competition, growth rates were unrelated to the percentage of colony border that was free of competitors. However, the identity of the competitor was important in the outcome of border contacts. At the beginning of the experiment, most border encounters of D. perlucidum were with solitary organisms, which in most cases were overgrown. These were progressively replaced by colonial ascidians and bryozoans, resulting mostly in stand-off interactions. Besides reducing asexual growth, spatial competition also affected female gonad production. Colonies free of competitors had a significantly higher proportion of zooids with ovaries. Thus, our findings show that spatial competition reduces both ascidian colony size and gonad production.
