Attitudes and experiences : qualitative perspectives on erectile dysfunction from the female partner

This study explored the woman’s experience of her partner’s erectile dysfunction (ED) focusing particularly on sexual experiences, relationship satisfaction, and communication. One hundred women completed a semistructured interview, providing information about how ED impacted her relationship with her partner. For some women, there was a sense of hopelessness and frustration surrounding their sex lives, while for others, her partner’s ED had led to efforts towards increasing non-physical intimacy and sexual communication. These findings demonstrate the importance of the relationship, including communication between the partners, in a women’s experience of her partners’ ED.

Provocation in New South Wales : the need for abolition

Over the past two decades significant debate has emerged surrounding the operation of the partial defence of provocation. Such debates have led to its abolition in several Australian and international jurisdictions where Government and Law Commission bodies have argued that provocation has operated in a gender biased way that is no longer reflective of community values and expectations of justice. In contrast to the Australian states of Tasmania, Victoria and Western Australia, who have transferred consideration of provocation to sentencing, New South Wales (NSW) has retained provocation as a partial defence to murder. Drawing upon in-depth interviews conducted with legal stakeholders and an analysis of recent case law, this article considers whether the operation of provocation in NSW is still in the best interests of justice, and, specifically, whether in practice it privileges one gender above the other. This research concludes that the continued operation of provocation in NSW raises key issues surrounding the legitimisation of male violence against women, the denial and minimisation of the harm caused by lethal domestic violence, and the continued inability of the law to appropriately respond to women who kill in the context of prolonged family violence.

The role of testosterone in bib size determination in the male house sparrow Passer domesticus, is age dependent

Secondary sexual signals are thought to indicate individual quality. In order to understand the evolutionary pressures that give rise to such traits it is important to understand the physiological mechanisms underlying their production. The black bib of the house sparrow Passer domesticus is known to function as a badge of social status in males. Past studies have found that the size of the bib in older males is determined, at least partly, by the androgen testosterone. The immunocompetence handicap hypothesis suggests that testosterone has a key role in maintaining honest signalling – it is both involved in the development or expression of sexual signals and is immunosuppressive. In this paper we test experimentally two hypo theses relating to bib size development, whether 1) testosterone is only immunosuppressive in conditions where the natural feedback loop from the testes has been removed, and 2) testosterone is, in addition to influencing the bib size of older males, responsible for the size of the bib in juvenile sparrows. In the first experiment we found that exogenous testosterone administered to intact males during the winter (when LH and FSH levels are very low and were not artificially increased by castration) caused significant immunosuppression, albeit in interaction with the stress hormone corticosterone. Second, we found that exogenous testosterone administration in castrated fledgling male house sparrows had no effect on subsequent post-juvenile moult bib size relative to controls. Our results suggest that in some circumstances testosterone can be immunosuppressive, but that its role in bib size determination is age-dependent.

Expression of the male reproduction-related gene (Mar-Mrr) in the spermatic duct of the giant freshwater prawn, Macrobrachium rosenbergii

Phosphorylated sperm proteins are crucial for sperm maturation and capacitation as a priori to their fertilization with eggs. In the freshwater prawn, Macrobrachium rosenbergii, a male reproduction-related protein (Mar-Mrr) was known to be expressed only in the spermatic ducts as a protein with putative phosphorylation and may be involved in sperm capacitation in this species. We investigated further the temporal and spatial expression of the Mar-Mrr gene using RT-PCR and in situ hybridization and the characteristics and fate of the protein using immunblotting and immunocytochemistry. The Mar-Mrr gene was first expressed in 4-week-old post larvae and the protein was produced in epithelial cells lining the spermatic ducts, at the highest level in the proximal region and decreased in the middle and distal parts. The native protein had a MW of 17 kDa and a high degree of serine/threonine phosphorylation. It was transferred from the epithelial cells to become a major protein at the anterior region of the sperm. We suggest that it is involved in sperm capacitation and fertilization in this open thelycal species and this is being investigated.

Physical activity initiatives for male factory workers : gatekeepers' perceptions of potential motivators and barriers

Objective: Worksites have been argued to be a key setting for physical activity promotion, particularly for lower-paid, less-skilled workers. These occupational groups are at increased risk of cardiovascular disease. There is no strong evidence in support of the efficacy of worksite fitness and physical activity interventions. This study assessed potential motivators and barriers to worksite physical activity initiatives for less-skilled workers.

Method: We conducted telephone interviews with 13 Victorian WorkCover insurance providers and 30 manufacturing industry worksite managers. The manufacturing industry was selected as it contains a substantial portion of workers from this high-risk occupational group.

Results: Most insurers incorporated physical activity elements into injury-prevention programs. Few worksite managers reported programs to encourage workers to be more active; they identified reduced premiums and lower-cost programs through insurers as possible motivators. Both groups identified workers' reluctance to participate in physical activity, lack of awareness of potential benefits and program cost as major barriers for worksite physical activity. Other barriers included potential adverse effects on productivity and increased injury risk.

Conclusions: Broader occupational health and safety policies and joint initiatives between insurers and worksite managers may have the potential to provide more opportunities for workers to be more active. However, the barriers identified outweighed the perceived benefits.

Implications: Without structural and regulatory changes or new incentives, the adoption of physical activity initiatives in Australian manufacturing-industry workplaces is unlikely.

Physical activity promotion for male factory workers : a realistic option?

Issue addressed: Worksites are a promising setting for health promotion initiatives. While there is an accumulated body of evidence indicating favourable health and cost outcomes, there have been difficulties identified in recruiting and influencing blue- collar workers. This descriptive study aimed to identify specific opportunities and barriers which may impact upon physical activity options at work for male blue-collar factory workers.

Methods: Fifteen manager interviews and worksite observations, and eight employee group discussions were conducted in manufacturing industry worksites.

Results: Several key barriers emerged which limit opportunities for blue-collar employees to participate in physical activity at work: time constraints; limited facilities; and lack of interest from management to facilitate physical activity due to limited resources and concerns about safety issues. Potential opportunities included the presence of change rooms, showers, outdoor areas suitable for physical activity, nearby parks and local fitness facilities, and occupational health and safety committees.

Conclusions: Increasing opportunities for workers to be active at work did not emerge as a priority of managers who may need to be convinced that allocating time and resources to physical activity is a wise investment and that workers need an environment that both supports and encourages participation in physical activity. The role of physical activity in relation to injury prevention and potential reductions in Workcover premiums is worthy of further investigation.

So what? While worksite physical activity promotion is a national health objective, there are numerous actual and perceived barriers to initiatives directed at factory workers. Rather than offering specific programs, it may be more productive to address work practices and environmental and regulatory barriers through established occupational health and safety channels. Information and education strategies to change the attitudes and beliefs of management and workers about these issues, as well as about the health benefits of physical activity, may also be helpful.

Male body image in real and virtual environments

My research investigated the relevance of men’s online avatars to their body image concerns in real life. The results revealed that the size and muscle of avatars are of clinical significance for certain men, particularly those who value and identify with the aesthetic properties of their avatars.
