Building realities less limited than their own : young people practising same sex attraction on the internet

The internet has met with mixed community reactions, especially when the focus is on young people's internet use. There are those who fear that the internet will introduce undesirable people and information into the home, leaving the young vulnerable and exploited. Alternatively, there are others who argue that the exclusion of young people from the internet is one of many examples of the diminishing public space that is made available to young people in this post-modern world. In this article we focus on the internet use of one ‘space deprived’ group of marginalized young people, those who are same-sex attracted. Regardless of some important changes in Australian culture and law, these young people's opportunities to openly live their sexual difference remain restricted. In this article we are interested in exploring the role of the internet as a space in which some important sexuality work can be done. What we found was that the internet was providing young people with the space to practise six different aspects of their sexual lives namely identity, friendship, coming out, intimate relationships, sex and community.

Cerebral cortex : an MRI-based study of volume and variance with age and sex

The aim of the present study was to examine quantitative differences in lobar cerebral cortical volumes in a healthy adult population. Quantitative volumetric MRI of whole brain, cerebral and cerebellar volumes was performed in a cross-sectional analysis of 97 normal volunteers, with segmented frontal, temporal, parietal and occipital cortical volumes measured in a subgroup of 60 subjects, 30 male and 30 female, matched for age and sex. The right cerebral hemisphere was larger than the left across the study group with a small (<1%) but significant difference in symmetry (P < 0.001). No difference was found between volumes of right and left cerebellar hemispheres. Rightward cerebral cortical asymmetry (right larger than left) was found to be significant across all lobes except parietal. Males had greater cerebral, cerebellar and cerebral cortical lobar volumes than females. Larger male cerebral cortical volumes were seen in all lobes except for left parietal. Females had greater left parietal to left cerebral hemisphere and smaller left temporal to left cerebral hemisphere ratios. There was a mild reduction in cerebral volumes with age, more marked in males. This study confirms and augments past work indicating underlying structural asymmetries in the human brain, and provides further evidence that brain structures in humans are differentially sensitive to the effects of both age and sex.

The ethics of care and treatment of sex offenders

The ethics of care acknowledges the importance of establishing and maintaining practices that help people to meet their needs, develop and protect basic capabilities for problem solving, emotional functioning, and social interaction, and avoid pain and suffering. In this article, we explore the contribution an ethics of care perspective can make to work with sex offenders. First, we briefly describe five classes of ethical problems evident in work with sex offenders. Second, the concept of care is defined and a justification for a version of care theory provided. Third, we apply the care ethical theory to ethical issues with sex offenders and demonstrate its value in responding to the five classes of problems outlined earlier.

Doing what your big sister does : sex, postfeminism and the YA chick lit series

Mass-marketed teen chick lit has become a publishing phenomenon and has begun to attract critical interest among children’s literature scholars. Much of this critical work, however, has shied away from robust critical assessment of the postfeminist conditions informing the production and reception of young adult series like Private, Gossip Girl and Choose Your Own Destiny. Existing analyses may nod to the origins of the genre in women’s chick lit, but do not investigate how the postfeminist construction of ‘empowered’ female (hetero) sexuality translates into chick lit for young adults. Paying particular attention to these issues, this paper draws on feminist critiques of postfeminism to interrogate the implications of the way these novels position readers to understand their sexuality. In doing so, it poses postfeminist criticism as an unconsidered yet significant framework to evaluate novels for teenage girls.

Staff perspectives of drug use issues among sex-on-premises attendees

Aims: Sex on premises venues (SOPV) have been given considerable attention, in particular when exploring the relationship between SOPV attendance and risk behaviours such as drug use and unsafe sex. Little attention has been given to the perspectives of those who work in these venues.

Methods: Semi-structured interviews were conducted with staff recruited from four SOPV in Sydney, Australia. Content analysis was performed to identify common themes.

Findings: Several themes emerged from the staff interviews. These themes concentrated on particular drugs of concern; interventions in place to deal with substance use and those under the influence; and that drug use among SOP patrons occurred at venues prior to attending SOPV.

Conclusions: Interviews with SOP workers showed that these venues face unique challenges that may not be encountered by other settings. SOPV staff has a detailed understanding of their clientele and their perspectives may be important not only when informing trends in substance use but also the development and distribution of harm reduction materials.

Absorbance of retinal oil droplets of the budgerigar : sex, spatial and plumage morph-related variation

Intraspecific variation in photoreceptor physiology is known in several vertebrate taxa, but is currently unknown in birds, despite many avian traits varying intraspecifically, and avian visual ecology encompassing a wide range of environments and visual stimuli, which might influence spectral sensitivity. Avian retinal photoreceptors contain light absorbing carotenoid-rich oil droplets that affect vision. Carotenoids are also important plumage components. However, our understanding of the regulation of carotenoids in oil droplets remains rudimentary. Among birds, Melopsittacus undulatus has probably the best-studied colour vision, shows profound intraspecific variation in plumage colour, and increased plasma carotenoids during moult. We used microspectrophotometry to determine whether a relationship exists between oil droplet carotenoid concentration and plumage pigmentation, and tested for sex and spatial variation in droplet absorbance across the retina. Absorbance of one variety of P-type droplets was higher in males. No relationship was found between droplet absorbance and plumage colour. We found a spatial pattern of droplets absorbance across the retina that matched a pattern found in another parrot, and other avian species. Our work provides insights into the development and maintenance of retinal oil droplets and suggests a common mechanism and function for carotenoid deposition in the retina across bird species.

Mothers adjust offspring sex to match the quality of the rearing environment

Theory predicts that mothers should adjust offspring sex ratios when the expected fitness gains or rearing costs differ between sons and daughters. Recent empirical work has linked biased offspring sex ratios to environmental quality via changes in relative maternal condition. It is unclear, however, whether females can manipulate offspring sex ratios in response to environmental quality alone (i.e. independent of maternal condition). We used a balanced within-female experimental design (i.e. females bred on both low- and high-quality diets) to show that female parrot finches (Erythrura trichroa) manipulate primary offspring sex ratios to the quality of the rearing environment, and not to their own body condition and health. Individual females produced an unbiased sex ratio on high-quality diets, but over-produced sons in poor dietary conditions, even though they maintained similar condition between diet treatments. Despite the lack of sexual size dimorphism, such sex ratio adjustment is in line with predictions from sex allocation theory because nutritionally stressed foster sons were healthier, grew faster and were more likely to survive than daughters. These findings suggest that mothers may adaptively adjust offspring sex ratios to optimally match their offspring to the expected quality of the rearing environment.

Bisexual parents and family diversity : findings from the work, love, play study

This article reports on findings from the Work, Love, Play study, an Australian/New Zealand study of same-sex attracted parents. There were 48 parents in this study who identified as bisexual. There was a diversity of contexts in which people in this sample were parenting: heterosexual relationships, same-sex relationships, coparenting with ex-partners or nonpartners, and sole parenting. A large number of these bisexual parents had experience of divorce or separation since having children, but most reported positive aspects to their parenting relationships with ex-partners. Very few people in this study reported that bisexual identity created difficulties for them as a parent.

Sex in Japan's globalization, 1870-1930: prostitutes, emigration and nation building

Based on archival research undertaken in Japan and Britain, Mihalopoulos offers a new perspective on the relations between gender hierarchies and the political economy in a newly modernized Japan. The industrialization of Japan in the late nineteenth century coincided with attempts to establish new trade links abroad. The peasant class were sent overseas as ‘free labourers’ in a state-sponsored programme that also sought to maintain traditional codes of behaviour and morally acceptable forms of work. This study examines the particular impact of these restrictions on Japanese prostitutes abroad and reveals how the freedom offered to the poor by the state was limited and highly selective.

Molecular sex-typing in shorebirds: a review of an essential method for research in evolution, ecology and conservation

Knowing the correct sex of individuals is essential both for research in evolutionary ecology and for practical conservation. Recent molecular advances have produced cheap, quick and reliable methods for sexing birds including chicks, juveniles, immatures and adults. Shorebird researchers have not yet fully utilised these advances. Here we provide an overview of work in this area to date with two objectives: (i) to review the major applications of molecular sexing and findings of shorebird research so far, and (ii) to provide an essential guide on how to carry out molecular sexing using current methods whilst avoiding methodological pitfalls. We encourage shorebird researchers to make better use of molecular sex-typing techniques in studies of conservation, migration, foraging ecology and breeding behaviour.

Molecular determination of sex-ratio in Yellowhammer Emberiza citrinella offspring

Theory predicts skewed offspring sex-ratios in a range of situations in which the economics of producing the two sexes differ. Offspring sex-ratio skews in birds are relatively scarcely observed compared to other taxa. This could be because avian molecular sexing techniques, which allow young birds to be sexed, have only recently become available. Alternatively, birds may be largely constrained from adaptively manipulating the sex-ratio of their offspring. We used a recently-developed molecular sexing technique for birds to sex 420 Yellowhammer Emberiza citrinella offspring from 168 clutches found in Oxfordshire. Clutch sex-ratio of the population did not depart from the expected binomial distribution, and there was no variation in clutch sex-ratio with laying date, breeding attempt, or a variety of habitat variables which were predicted to differentially affect the survival and future reproductive success of offspring of the two sexes. There was no difference in size or growth rate of the sexes and nestling mortality was not sex-biased. Hence, although we can identify possible advantages of manipulating the sex-ratio in this species, it seems not to be used as a breeding strategy. Given the lack of consistent evidence for skewed avian offspring sex-ratios, more experimental work is required to determine whether, and how, birds may adaptively manipulate their offspring sex-ratio.

The Supervision of Known Sex Offenders in the Community: Monitoring Progress and Providing Feedback

Case management is the process by which most known sex offenders who live in the community are currently supervised. However, by itself, case management has been shown to have only a modest impact on rates of re-offending, and it is only when case work and/or treatment sessions are introduced, that the benefits become apparent. This paper considers how routinely collecting and feeding back standardized data about client progress towards supervisory goals can be integrated into the offender supervision and case management process. Based on methods that have been shown to be associated with enhanced outcomes in mental health, it is suggested that the implementation of feedback approaches have the potential to both enhance the case management process and improve the effectiveness of those policies which require it.

Sex as a determinant of relapse incidence and progressive course of multiple sclerosis

The aim of this work was to evaluate sex differences in the incidence of multiple sclerosis relapses; assess the relationship between sex and primary progressive disease course; and compare effects of age and disease duration on relapse incidence. Annualized relapse rates were calculated using the MSBase registry. Patients with incomplete data or <1 year of follow-up were excluded. Patients with primary progressive multiple sclerosis were only included in the sex ratio analysis. Relapse incidences over 40 years of multiple sclerosis or 70 years of age were compared between females and males with Andersen-Gill and Tweedie models. Female-to-male ratios stratified by annual relapse count were evaluated across disease duration and patient age and compared between relapse-onset and primary progressive multiple sclerosis. The study cohort consisted of 11 570 eligible patients with relapse-onset and 881 patients with primary progressive multiple sclerosis. Among the relapse-onset patients (82 552 patient-years), 48 362 relapses were recorded. Relapse frequency was 17.7% higher in females compared with males. Within the initial 5 years, the female-to-male ratio increased from 2.3:1 to 3.3:1 in patients with 0 versus ≥4 relapses per year, respectively. The magnitude of this sex effect increased at longer disease duration and older age (P < 10−12). However, the female-to-male ratio in patients with relapse-onset multiple sclerosis and zero relapses in any given year was double that of the patients with primary progressive multiple sclerosis. Patient age was a more important determinant of decline in relapse incidence than disease duration (P < 10−12). Females are predisposed to higher relapse activity than males. However, this difference does not explain the markedly lower female-to-male sex ratio in primary progressive multiple sclerosis. Decline in relapse activity over time is more closely related to patient age than disease duration.

Professional views on the management of sex offenders in the community

Sex offender registration and community notification schemes form an increasingly important part of public policy relevant to the management of known sex offenders in the community. Critics of these policies not only point to the lack of empirical evidence that is currently available to support their impact on reoffending, but also the disproportionate and potentially iatrogenic effects that they have on offenders. However, there have been few attempts to understand these issues from the perspective of those practitioners who work on a daily basis with sex offenders in the community. These professionals are uniquely placed to contribute to an understanding of effective risk management and, as such, this article presents an analysis of the perspectives of a group of experienced practitioners and how this practice-based wisdom might inform the development of sex offender public policy.
