Strategies for improving safety performance of repair, maintenance, minor alteration and addition (RMAA) works

Purpose Managing and maintaining infrastructure assets are one of the indispensible tasks for many government agencies to preserve the nations' economic viability and social welfare. To reduce the expenditures over the life-cycle of an infrastructure asset and extend the period for which the asset performs effectively, proper repair and maintenance are essential. While repair, maintenance, minor alteration and addition (RMAA) sector is expanding in many developed cities, occurrences of fatalities and injuries in this sector are also soaring. The purposes of this paper are to identify and then evaluate the various strategies for improving the safety performance of RMAA works. Design/methodology/approach Semi-structured interviews and two rounds of Delphi survey were conducted for data collection. Findings Raising safety awareness of RMAA workers and selecting contractors with a good record of safety performance are the two most important strategies to improve the safety performance in this sector. Technology innovations and a pay-for-safety scheme are regarded as the two least important strategies. Originality/value The paper highlights possible ways to enhance safety of the rather under-explored RMAA sector in the construction industry.

Introduction - research ethics : women, sex, and gender in biomedical research

The ethical governance of biomedical research is an area of intense international debate. Scholars argue about who should regulate and how, the appropriate role for ethics committees, what kind of research should be included, and who should be involved in monitoring compliance. A particular aspect of these debates concerns the inclusion of women as research participants and the efforts to ensure that researchers consistently investigate questions of sex and gender in health research. There is increasing evidence of the role of sex in the manifestation and course of some illnesses and their treatment. Moreover, evidence suggests that gendered expectations also affect health outcomes. This special issue investigates how researchers are addressing these issues and debates the appropriate roles of policy makers, ethicists, and lawyers in ensuring that sex and gender differences are taken into account in the development, conduct, and reporting of health research.

Do sex and atopy influence cough outcome measurements in children?

Background Despite the commonality of cough and its burden, there are no published data on the relationship between atopy or sex on objectively measured cough frequency or subjective cough scores in children. In 202 children with and without cough, we determined the effect of sex and atopy on validated cough outcome measurements (cough receptor sensitivity [CRS], objective cough counts, and cough scores). We hypothesized that in contrast to adult data, sex does not influence cough outcome measures, and atopy is not a determinant of these cough measurements. Methods We combined data from four previous studies. Atopy (skin prick test), the concentration of capsaicin causing two and five or more coughs (C2 and C5, respectively), objectively measured cough frequency, and cough scores were determined and their relationship explored. The children’s (93 girls, 109 boys) mean age was 10.6 years (SD 2.9), and 56% had atopy. Results In multivariate analysis, CRS was influenced by age (C2 coefficient, 5.9; P = .034; C5 coefficient, 29.1; P = .0001). Atopy and sex did not significantly influence any of the cough outcomes (cough counts, C2, C5, cough score) in control subjects and children with cough. Conclusions Atopy does not influence important cough outcome measures in children with and without chronic cough. However, age, but not sex, influences CRS in children. Unlike adult data, sex does not affect objective counts or cough score in children with and without chronic cough. Studies on cough in children should be age matched, but matching for atopic status and sex is less important.

Sex, love and abuse : discourses on domestic violence and sexual assault

Sex, Love and Abuse intervenes in a timely way on some important issues that have become 'elephants in the room' for academic and policy considerations around sexual violence and abuse. In so doing, this book draws upon a range of literatures and novel empirical sources to encourage critical thinking about the relationship between sex, love and abuse, examining crimes including sexual assault, pornography, child sexual abuse and domestic violence. This provocative book seeks to destabilize essentialist understandings of these phenomena with a view to identifying the subtle and complex nature of relationships, which often defy easy explanation and categorisation. Focusing on theories, public discourses and moral ideals, Hayes connects romantic love, intimacy and harm in a unique philosophical analysis, exploring abuse in relationships and how such abuse is fostered.

Sex differences in the perceived value of outreach and museums/science centres in students' decisions to enrol in university science, technology and engineering courses

This paper reports a number of findings from the Interests and Recruitment in Science (IRIS) study carried out in Australia in 2011. The findings concern the perceptions of first year university students in science, technology and engineering courses about the influence of museums/science centres and outreach activities on their choice of course. The study found that STE students in general tended to rate museums/science centres as more important in their decisions than outreach activities. However, a closer examination showed that females in engineering courses were significantly more inclined to rate outreach activities as important than were males in engineering courses or females in other courses. The implications of this finding for strategies to encourage more young women into engineering are discussed.

The rurality of sex : community resistance and objection to prostitution in rural and regional areas throughout Queensland

Queensland legislation currently defines two legally recognised forms of prostitution: sex work conducted in a licensed brothel; or, sex work conducted privately by a sole operator.Despite prostitution’s legality in these contexts, it continues to be heavily controlled and restricted by authorities, while also being rejected by surrounding communities. Such resistance towards prostitution is demonstrated in Queensland where over 200 towns with populations of less than 25,000 have been successful in applying for exemption from the development of licensed brothels in those jurisdictions (Prostitution Licensing Authority 2012). Queensland’s legislative acknowledgement of prostitution as a legal act, while simultaneously allowing small communities to reject such activity, seems somewhat contradictory. This paper will provide a theoretical examination of common community objections to prostitution in modern society, determining whether such attitudes are applicable to communities in rural and regional Queensland towns. Additionally, this paper will incorporate an analysis of rural and urban areas via the ‘gemeinschaft‐gesellschaft’ dichotomy to understand the potential justification for opposing areas being subject to differential treatment under the law.

Human trafficking involving marriage and partner migration to Australia

In this report, what is known about human trafficking involving marriage and partner migration to Australia is described, drawing on primary information obtained from victim/survivor testimonies, stakeholder knowledge and expertise, and reported cases that progressed through the Australian justice system. It confirms what some stakeholders in the human trafficking area have long suspected—that marriage and partner migration have been used to facilitate the trafficking of people into Australia.

Motor Accident Insurance Act 1994 s45 - whether obligation to co-operate may authorise order requiring commencement of proceedings by minor prior to expiration of limitation period

In Australian Associated Motor Insurers Ltd v McPaul; Council of the City of Gold Coast v McPaul [2005] QSC 278 the applicant insurer sought an order requiring a claimant who had been injured in a motor vehicle accident some years earlier when he was five years old to commence a proceeding to determine the question of the applicant's liability to him. The applicant's interest in seeking the order was to avoid the prejudice which could follow from further delay, particularly delay until the respondent became obliged to commence proceedings to avoid a limitations bar.

Cholesterol regulates Syntaxin 6 trafficking at trans-Golgi network endosomal boundaries.

Inhibition of cholesterol export from late endosomes causes cellular cholesterol imbalance, including cholesterol depletion in the trans-Golgi network (TGN). Here, using Chinese hamster ovary (CHO) Niemann-Pick type C1 (NPC1) mutant cell lines and human NPC1 mutant fibroblasts, we show that altered cholesterol levels at the TGN/endosome boundaries trigger Syntaxin 6 (Stx6) accumulation into VAMP3, transferrin, and Rab11-positive recycling endosomes (REs). This increases Stx6/VAMP3 interaction and interferes with the recycling of αVβ3 and α5β1 integrins and cell migration, possibly in a Stx6-dependent manner. In NPC1 mutant cells, restoration of cholesterol levels in the TGN, but not inhibition of VAMP3, restores the steady-state localization of Stx6 in the TGN. Furthermore, elevation of RE cholesterol is associated with increased amounts of Stx6 in RE. Hence, the fine-tuning of cholesterol levels at the TGN-RE boundaries together with a subset of cholesterol-sensitive SNARE proteins may play a regulatory role in cell migration and invasion.

Changes to commercial service provision among sex workers from Queensland, Australia

Introduction: The role of commercial sex in facilitating infection transmission is a subject of ongoing empirical enquiry, with little attention to the variety and extent of ‘non-traditional’ commercial services that pose a lesser risk of infection. This study sought to examine the supply and demand of a wide range of traditional and non-traditional commercial sexual services among sex workers and their clients from Queensland, Australia. Methods: Cross-sectional convenience sampling was used to compare female sex workers in 1991 (n=200, aged 16-46 years) and 2003 (n=247, aged 18-57 years) and from male clients in 2003. The client sample comprised 160 male clients aged between 19 and 72 years. Results: Over the comparison period there was a significant increase in the provision of ‘exotic’ or non-traditional sexual services. In 2003, the availability of bondage and discipline, submission, fantasy, use of sex toys, golden showers, fisting and lesbian double acts had increased dramatically, while ‘traditional’ services had mostly remained at similar levels. Moreover, the proportion of sex workers in some industry sectors providing ‘exotic’ commercial services seem to have risen over time. Conclusion: Undoubtedly, the sex industry has professionalised and now includes more sophisticated and specialized suppliers. As with any commercial business, the diversification of services is largely driven with client demand, with the ‘menu’ being generally broader than the majority of client preferences. However, although clients demands for particular commercial sexual services seems to have been met, with regard to anal sex and anal play, supply has failed to meet client demand. Disclosure of Interest Statement: Funding for the 2003 study was provided by the Prostitution Licensing Authority. Acknowledgement and sincere thanks to the men and women who participated in this study.

A Statutory interpretation EXperience : putting the SEX into statutory interpretation

With the growing proliferation of statute laws, the skill of statutory interpretation is an increasingly important aspect of legal practice. Despite the importance, statutory interpretation can be a challenging area of law to teach to undergraduate law students, who may find the topic dry and disengaging when taught through traditional methods. Such disengagement may adversely affect knowledge retention, particularly if the material is taught in the first or second year of study and not explicitly reinforced in subsequent years. Concern over the present standard of statutory interpretation skills being exhibited by practitioners, has prompted the Chief Justice of the Supreme Court of Queensland to contact law schools, enquiring how and to what extent statutory interpretation is being taught...

‘It's all scientific to me’ : focus group insights into why young people do not apply safe-sex knowledge

Despite rising levels of safe-sex knowledge in Australia, sexually transmitted infection notifications continue to increase. A culture-centred approach suggests it is useful in attempting to reach a target population first to understand their perspective on the issues. Twenty focus groups were conducted with 89 young people between the ages of 14 and 16 years. Key findings suggest that scientific information does not articulate closely with everyday practice, that young people get the message that sex is bad and they should not be preparing for it and that it is not appropriate to talk about sex. Understanding how young people think about these issues is particularly important because the focus groups also found that young people disengage from sources of information that do not match their own experiences.

The adhesion molecule L1 regulates transendothelial migration and trafficking of dendritic cells

The adhesion molecule L1, which is extensively characterized in the nervous system, is also expressed in dendritic cells (DCs), but its function there has remained elusive. To address this issue, we ablated L1 expression in DCs of conditional knockout mice. L1-deficient DCs were impaired in adhesion to and transmigration through monolayers of either lymphatic or blood vessel endothelial cells, implicating L1 in transendothelial migration of DCs. In agreement with these findings, L1 was expressed in cutaneous DCs that migrated to draining lymph nodes, and its ablation reduced DC trafficking in vivo. Within the skin, L1 was found in Langerhans cells but not in dermal DCs, and L1 deficiency impaired Langerhans cell migration. Under inflammatory conditions, L1 also became expressed in vascular endothelium and enhanced transmigration of DCs, likely through L1 homophilic interactions. Our results implicate L1 in the regulation of DC trafficking and shed light on novel mechanisms underlying transendothelial migration of DCs. These observations might offer novel therapeutic perspectives for the treatment of certain immunological disorders.
