Sustaining safe sex: a longitudinal study of a sample of homosexual men.

Abstract: Objective To assess the maintenance of safe sexual practice. (We use the term ‘safe’ sex throughout the paper, since ‘safe’ is the term adopted by the Australian National Committee on AIDS.) Design Maintenance was assessed by comparing sexual behaviour with both regular and casual partners reported in a 1986/1987 survey (time 1) with behaviour reported in a second survey in 1991 (time 2). Method The 145 homosexually active participants were a non-clinical sample recruited in 1986/1987 by advertisement and followed-up in 1991. A structured questionnaire was administered at both times. Items included questions about the nature of the men's sexual relationships and their sexual practices. Results Our findings indicate that the majority of men had sustained safe sex practices. HIV prevention strategies adopted included condom use, avoidance of anal intercourse and negotiated safety (i.e., the negotiated practice of unprotected anal intercourse within regular partnerships of concordant serostatus). Conclusions Negotiated safety is not the same as relapse.

Footwear characteristics and foot problems in older people.

Abstract: Background: Foot problems are common in older people, however the contribution of incorrectly fitting footwear and heel elevation to the development of foot pain and deformity has no

Men, Sex, and Homosociality How Bonds between Men Shape Their Sexual Relations with Women

Abstract: Male-male social bonds have a powerful influence on the sexual relations of some young heterosexual men. Qualitative analysis among young men aged eighteen to twenty-six in Canberra, Australia, documents the homosocial organization of men's heterosexual relations. Homosociality organizes men's sociosexual relations in at least four ways. For some of these young men, male-male friendships take priority over male-female relations, and platonic friendships with women are dangerously feminizing. Sexual activity is a key path to masculine status, and other men are the audience, always imagined and sometimes real, for one's sexual activities. Heterosexual sex itself can be the medium through which male bonding is enacted. Last, men's sexual storytelling is shaped by homosocial masculine cultures. While these patterns were evident particularly among young men in the highly homosocial culture of a military academy, their presence also among other groups suggests the wider influence of homosociality on men's sexual and social relations.

A multiparent advanced generation inter-cross population for genetic analysis in wheat

Abstract: We present the first results from a novel multiparent advanced generation inter-cross (MAGIC) population derived from four elite wheat cultivars. The large size of this MAGIC population (1579 progeny), its diverse genetic composition and high levels of recombination all contribute to its value as a genetic resource. Applications of this resource include interrogation of the wheat genome and the analysis of gene-trait association in agronomically important wheat phenotypes. Here, we report the utilization of a MAGIC population for the first time for linkage map construction. We have constructed a linkage map with 1162 DArT, single nucleotide polymorphism and simple sequence repeat markers distributed across all 21 chromosomes. We benchmark this map against a high-density DArT consensus map created by integrating more than 100 biparental populations. The linkage map forms the basis for further exploration of the genetic architecture within the population, including characterization of linkage disequilibrium, founder contribution and inclusion of an alien introgression into the genetic map. Finally, we demonstrate the application of the resource for quantitative trait loci mapping using the complex traits plant height and hectolitre weight as a proof of principle. © 2012 CSIRO.
