Sexual segregation is best known in sexually dimorphic ungulates. Many hypotheses have been proposed to explain the evolution of sexual segregation in ungulates, but all are reducible to the influence of two factors: body size and sex-specific reproductive strategy. Definitive tests of these hypotheses are lacking in ungulates because these factors are confounded, all males being somewhat larger than females. Kangaroos represent a parallel radiation of terrestrial herbivores, but their populations are composed of a spectrum of adult body sizes, ranging from small males the same size as females to large males more than twice the size. We exploited this heteromorphism to assess the independent influences of size and sex in these ungulate analogues. We conducted a preliminary study of western grey kangaroos (Macropus fuliginosus) in north-western Victoria, Australia. Adult males predominately occupied grassland habitat, whereas females occurred mostly in lakebed, woodland and shrubland. Single-sex groups occurred more often than expected during the non-mating season. The diet of large males had the highest proportion of grass, and females had the least. These initial results indicate that both size and sex influence segregation in this species, confirming the worth of kangaroos as marsupial models for research into the evolution of sexual segregation.

This work conducts a comprehensive historical review and analysis of the legislative principles for mandatory reporting of child sexual abuse in each State and Territory of Australia. The research traces and explains all the significant changes in the development of the laws in each jurisdiction since their inception in 1969 to the year 2013. The research also identifies why the legislation changed in each jurisdiction, covering research into publicly available records, focusing on significant government inquiries and law reform reports, and parliamentary debates. The research is situated within a treatment of the modern discovery of child sexual abuse as a widespread phenomenon of significant public health concern.

In this paper, a class of unconditionally stable difference schemes based on the Pad´e approximation is presented for the Riesz space-fractional telegraph equation. Firstly, we introduce a new variable to transform the original dfferential equation to an equivalent differential equation system. Then, we apply a second order fractional central difference scheme to discretise the Riesz space-fractional operator. Finally, we use (1, 1), (2, 2) and (3, 3) Pad´e approximations to give a fully discrete difference scheme for the resulting linear system of ordinary differential equations. Matrix analysis is used to show the unconditional stability of the proposed algorithms. Two examples with known exact solutions are chosen to assess the proposed difference schemes. Numerical results demonstrate that these schemes provide accurate and efficient methods for solving a space-fractional hyperbolic equation.

In this paper, we derive a new nonlinear two-sided space-fractional diffusion equation with variable coefficients from the fractional Fick’s law. A semi-implicit difference method (SIDM) for this equation is proposed. The stability and convergence of the SIDM are discussed. For the implementation, we develop a fast accurate iterative method for the SIDM by decomposing the dense coefficient matrix into a combination of Toeplitz-like matrices. This fast iterative method significantly reduces the storage requirement of O(n2)O(n2) and computational cost of O(n3)O(n3) down to n and O(nlogn)O(nlogn), where n is the number of grid points. The method retains the same accuracy as the underlying SIDM solved with Gaussian elimination. Finally, some numerical results are shown to verify the accuracy and efficiency of the new method.

Background Child sexual abuse is a significant global problem in both magnitude and sequelae. The most widely used primary prevention strategy has been the provision of school-based education programmes. Although programmes have been taught in schools since the 1980s, their effectiveness requires ongoing scrutiny. Objectives To systematically assess evidence of the effectiveness of school-based education programmes for the prevention of child sexual abuse. Specifically, to assess whether: programmes are effective in improving students’ protective behaviours and knowledge about sexual abuse prevention; behaviours and skills are retained over time; and participation results in disclosures of sexual abuse, produces harms, or both. Search methods In September 2014, we searched CENTRAL, OvidMEDLINE, EMBASE and 11 other databases.We also searched two trials registers and screened the reference lists of previous reviews for additional trials. Selection criteria We selected randomised controlled trials (RCTs), cluster-RCTs, and quasi-RCTs of school-based education interventions for the prevention of child sexual abuse compared with another intervention or no intervention. Data collection and analysis Two review authors independently assessed the eligibility of trials for inclusion, extracted data, and assessed risk of bias.We summarised data for six outcomes: protective behaviours; knowledge of sexual abuse or sexual abuse prevention concepts; retention of protective behaviours over time; retention of knowledge over time; harm; and disclosures of sexual abuse.

A promising approach to the persistent problem of workplace sexual harassment (SH) is encouraging interventions by bystanders. Adopting a typology developed by Bowes-Sperry and O'Leary-Kelly that considers the level of immediacy and involvement of bystander interventions, this study explored 74 detailed descriptions of SH events that occurred in Australian workplaces. The findings reveal that despite the hidden nature of SH, there is significant involvement of actors who are not direct targets but their actions are frequently delayed, temporary or ineffective. The study makes two contributions to the study and practice of HRM. First, it provides important evidence of the different ways that bystanders respond to SH in real workplaces and the relative likelihood of these actions. Second, the study points to relevant contextual features evident in the scenarios described which determine if and how bystanders intervene. We discuss the utility of the bystander framework for future research and practice, including the development of bystander interventions as a potentially innovative response to the persistent and damaging problem of workplace SH.

Men are overwhelmingly responsible for sexual harassment against women in the workplace. However, the literature also points to less typical manifestations, including sexual harassment by men of other men and by women of men or other women. This article examines these atypical forms of sexual harassment, drawing on a census of all formal sexual harassment complaints lodged with Australian equal opportunity commissions over a six-month period. The analysis reveals some important distinctions and similarities across groups of atypical complaints, as well as between atypical groups and ‘classic’ sexual harassment complaints where men harass women. The article contributes to the relatively undeveloped literature on these less visible forms of sexual harassment and highlights both theoretical and pragmatic challenges in better understanding workplace sexual harassment ‘at the margins’.

This paper introduces research in progress that examines how queer women perform sexual identity across social media platforms. Applying a lens of queer theory and Actor Network Theory, it discusses women’s embodied self-representations as taking on forms that both conform to and elaborate upon the selfie genre of digital representation. Acknowledging similarities and differences across platforms, specifically between Instagram and Vine, a novel walkthrough method is introduced to identify platform characteristics that shape identity performances. This method provides insights into the role of platforms in identity performances, which can be combined with analysis of user-generated content and interviews to better understand digital media’s constraints and affordances for queer representation.

This paper explores a key issue identified in two studies of factors influencing the success of international and culturally and linguistically diverse (CALD) higher degree research graduate students. The studies include “A model for research supervision of international students in engineering and information technology disciplines” (MRS), which focused on identifying factors that influence successful supervision of culturally and linguistically diverse (CALD) and international higher degree research (HDR or graduate) students in Engineering and IT disciplines in three Australian universities, and “Culture, language and the whole graduate experience: Exploring best practices in international graduate supervision” (BPS), which focussed on exploring perceptions regarding best practices in graduate supervision by diverse stakeholders across Australia. Findings suggest most supervisors do not differentiate between international (or CALD) graduate students and non-CALD(domestic) students in terms of factors influence success in graduate studies.

This chapter discusses the fast emerging challenges for Malay and Muslim sexual minority storytellers in the face of an aggressive state-sponsored Islamisation of a constitutionally secular Malaysia. I examine the case of Azwan Ismail, a gay Malay and Muslim Malaysian who took part in the local ‘It Gets Better’ project, and who suffered an onslaught of hostile comments from fellow Malay Muslims. Azwan’s experience makes one question how a message of discouraging suicidal tendencies among sexual minority youths can be so vehemently misperceived. Azwan’s existential challenges – stemming from the tension between his own constructions of self and those of others – (re)present a unique challenge in the long struggle for human rights. In my examination of the arising contradictions, I highlight the challenges for Azwan’s existential self – one who is deemed morally bankrupt by hostile audiences. The purist Sunni Islam agenda in a constitutionally secular Malaysia not only rejects the human rights of the sexual minorities in Malaysia but has also influenced, and is often a leading hostile voice in both regional and international blocs. This self-righteous, supremacist and authoritarian Islam discourages discourse and attacks all differing opinions. This resulting disabling environment for vulnerable, minority communities and their human rights manifests in State-endorsed discrimination, compulsory counselling, forced rehabilitation and criminalisation. It places the rights of the sexual minorities to live within such a society in doubt. In discussing the arising issues, I draw upon literature that investigates the way in which personal stories have traditionally been used to advance human rights. Included too, is the significance and implications of the work by social psychologists in explaining the loss of credibility of personal stories. I then advance an analytical framework that will allow storytelling as a very individual form of witnessing to reclaim and regain its ‘truth to power’.

The concept nursing grand rounds (NGR) has been reported in the nursing literature since the 1960s. Many of the reported initiatives are based on a presentation forum in the manner of medical grand rounds, as an approach to undergraduate education, or as a means to monitor patients. Among the points of difference in the design of the pilot project undertaken in a busy surgical ward to investigate the effectiveness of NGR in increasing nurses work satisfaction was the inclusion of the nursing librarian as an integral part of the NGR team and processes which previously has not reported in the literature. The nursing librarian’s role was to search the literature and find the best evidence on the predetermined patient topic prior to the NGR to enable the nurse presenting to integrate the research findings into the presentation of the patient. The nursing librarian attended each NGR and commented where appropriate on the level of evidence. Nurses discussed current practice and the impact the retrieved literature would have on patient care comparing best practice with current practice. Outcomes of this project include in some cases change in practice, change in culture where NGRs are now embedded into ward culture, NGR extended to other wards, enthusiasm for EBP, the initiation of a “super searcher” model where the nursing librarian is more of a consultant and develops the searching skills of nominated nurses who become the resource on the ward.

Sexual harassment of women in medicine in the Australian medical profession is a serious problem which presents substantial legal, ethical and cultural questions for the medical profession. Women have enforceable legal rights to gender equality and freedom from sexual harassment in the workplace. Both individual offenders and their employers face significant legal consequences for sexual harassment. Individual medical practitioners and employers need to understand their legal and ethical responsibilities in this context. This article analyses four areas of legal liability in every State and Territory which apply to individual offenders and employers: criminal law, discrimination law, civil law, and contract law. It also analyses ethical duties owed by doctors towards their colleagues under professional regulatory schemes. The analysis shows that individual doctors and their employers have clear legal and ethical obligations to prevent sexual harassment. On legal and ethical grounds, medical employers, professional colleges and associations, and regulators need to improve gender equality and professional culture in medicine. A five-step model for cultural change is proposed.

Australian fundraisers and their organisational leaders (CEOs and board members) diverge sometimes in how they think about fundraising. In fact, eight key differences emerged in the recent Australian study that sparked this paper. A strong fundraising/leadership accord in attitudes toward fundraising would seem to be important, especially in tightened funding regimes. Both demand and competition for funding beyond the government dollar is growing. Many organisations are moving into community fundraising for the first time due to imperilled government funding. The sophistication of all donation sources is likewise on the rise. These factors add complexity to the fundraising role and to the task of boards and CEOs in managing fundraising strategy and activity. Some variances in professional outlook might be predictable between fundraisers and fundraising organisation leaders. However, the differences found in our study are in areas that potentially affect the organisation’s ability to fill its mission. It is advisable then to ‘mind the gap’ and also to explore it.

This study applies a narrative analysis of the first two judicial decisions on sexual harassment in Japan to test claims of a culture of gender bias in Japanese judicial attitudes towards victims of sexual violence. Although the results do not provide an unambiguous support or rebuttal of gendered justice in Japan, they do reveal some of the dangers of narrative analysis as a basis for making generalizable claims about how law functions in Japanese society.

Rind and Tromovitch (2007) raised four concerns relating to our article (Najman, Dunne, Purdie, Boyle, & Coxeter, 2005. Archives of Sexual Behavior, 34, 517-526.) which suggested a causal association between childhood sexual abuse (CSA) and adult sexual dysfunction. We consider each of these concerns: magnitude of effect, cause and effect, confounding, and measurement error. We suggest that, while the concerns they raise represent legitimate reservations about the validity of our findings, on balance the available evidence indicates an association between CSA and sexual dysfunction that is of "moderate" magnitude, probably causal, and unlikely to be a consequence of confounding or measurement error.
