Queer criminological work is at the forefront of critical academic criminology, responding to the exclusion of queer communities from criminology, and the injustices that they experience through the criminal justice system. This volume draws together both theoretical and empirical contributions that develop the growing scholarship being produced at the intersection of 'queer' and 'criminology'. Reflecting the diversity of research that is undertaken at this intersection, the contributions to this volume offer a deeper theoretical and conceptual development of this field alongside empirical research that illustrates the continued relevance and urgency of such scholarship. The contributions consider what it means to be queering criminology in the current political, social, and criminological climate, and chart directions along which this field might develop in order to ensure that greater social and criminal justice for LGBTIQ communities is achieved.

This article argues identifying as lesbian, gay, bisexual, transgender, intersex, queer and/or questioning (LGBTIQ) in rural spaces can produce specific types of policing experiences. While some literature examines the experiences of LGBTIQ people with police, very little has focused on how rurality explicitly shapes these experiences. This is significant considering research highlights how rurality can be connected to pronounced experiences of homophobia and trans-phobia. The article highlights examples from three research projects that explored: LGBTIQ young people's interactions with police; LGBTI people's interactions with police liaison services; and LGBTIQ-identifying police officers. The examples demonstrate the need for further research to examine how policing “happens” with rural LGBTIQ people to ensure more accountable policing policies and practice, and to highlight the complexities of localized, rural policing contexts that can both support and marginalize LGBTIQ people.

This paper considers the impossibility of erasing historical policing of LGBTIQ people. Significant events of LGBTIQ policing may appear to fade into the past and we perhaps assume they literally disappear – not discussed, not thought about, and erased from cultural memory. At times we see evidence of an almost nostalgic contemplation about LGBTIQ policing of the past embedded in the notion that we have moved beyond that point to the future, never to return to those histories. If we draw on the work of Foucault, an impossibility becomes apparent. Foucault suggests that discursive traces circulate in discourse and they emerge and re-emerge to shape future discourses. This paper ruminates on a case example, particularly the policing of the Gay and Lesbian Mardi Gras in Sydney, Australia, in 2013. We argue this case demonstrates Foucault’s understanding of discursive history in action: it shows how the remnant traces of historical LGBTIQ policing can re-emerge to profoundly shape LGBTIQ-police relations in the present. In addition to the case, we draw on qualitative data showing how ideas about historical LGBTIQ policing are rehearsed in a consistent cycle of iteration and reiteration through the musings of research participants across three different projects on LGBTIQ policing. We conclude therefore that LGBTIQ policing in the past may never be erased because moments reminiscent of historical LGBTIQ policing are always already circulating and undermining the governmental work of policing organisations in the present.

All of Us is a ground-breaking Australian government approved anti-bullying educational resource comprised of seven online videos that feature gender diverse, sexual diverse and intersex youths. The videos, along with unit guides and student handouts, have been designed to address a gap in high school curriculum as they teach not just about sexual diversity and gender diversity but also the values of empathy and respect, which has been demonstrated to improve students’ wellbeing and educational engagement. The resource captures the real life experiences of lesbian, gay, bisexual, transgender and intersex young people through a collection of short videos and teaching activities that are aligned to the Year 7/8 Health and Physical Education learning area of the Australian Curriculum. All Of Us has been developed to have a real impact on student attitudes towards lesbian, gay, bisexual, transgender and intersex people and to encourage whole school change that affirms and supports the right of all students, staff and families to feel safe at school. This free video resource is widely available and allows all schools, regardless of experience, location or funding, the chance to create an environment where every student can learn, every teacher can teach and every family can belong from the beginning of 2016. The resource was launched on Thursday, 26 November 2015 at Treasury Theatre, 1 Macarthur St, Melbourne. The launch was attended by almost 200 people including former Safe Schools Coalition Ambassador Jason Ball, Victorian Commissioner for Gender and Sexuality Ro Allen, Chris Bush, Executive Producer of All Of Us, Micah Scott, CEO of Minus18, All Of Us Margot Fink; Safe Schools Coalition Victoria's Manager Roz Ward and; Sally Richardson, National Program Director of Safe Schools Coalition Australia.

There are currently many changes happening in nursing and healthcare in Australia. Healthcare reform has been high on the national government agenda and has created many changes in healthcare including eHealth. Healthcare information technologies and informatics are providing many challenges and excitement for the future of healthcare in Australia. The challenge for professional nursing organisations and nursing leaders of Australia is to be proactive in developments and initiatives for nursing to remain visible and viable in health care systems to safeguard the profession for the future as health care reform is implemented.

Food processing industry generates substantial high organic wastes along with high energy uses. The recovery of food processing wastes as renewable energy sources represents a sustainable option for the substitution of fossil energy, contributing to the transition of food sector towards a low-carbon economy. This article reviews the latest research progress on biofuel production using food processing wastes. While extensive work on laboratory and pilot-scale biosystems for energy production has been reported, this work presents a review of advances in metabolic pathways, key technical issues and bioengineering outcomes in biofuel production from food processing wastes. Research challenges and further prospects associated with the knowledge advances and technology development of biofuel production are discussed.

Disease maps are effective tools for explaining and predicting patterns of disease outcomes across geographical space, identifying areas of potentially elevated risk, and formulating and validating aetiological hypotheses for a disease. Bayesian models have become a standard approach to disease mapping in recent decades. This article aims to provide a basic understanding of the key concepts involved in Bayesian disease mapping methods for areal data. It is anticipated that this will help in interpretation of published maps, and provide a useful starting point for anyone interested in running disease mapping methods for areal data. The article provides detailed motivation and descriptions on disease mapping methods by explaining the concepts, defining the technical terms, and illustrating the utility of disease mapping for epidemiological research by demonstrating various ways of visualising model outputs using a case study. The target audience includes spatial scientists in health and other fields, policy or decision makers, health geographers, spatial analysts, public health professionals, and epidemiologists.

Historically, school leaders have occupied a somewhat ambiguous position within networks of power. On the one hand, they appear to be celebrated as what Ball (2003) has termed the ‘new hero of educational reform'; on the other, they are often ‘held to account’ through those same performative processes and technologies. These have become compelling in schools and principals are ‘doubly bound’ through this. Adopting a Foucauldian notion of discursive production, this paper addresses the ways that the discursive ‘field’ of ‘principal’ (within larger regimes of truth such as schools, leadership, quality and efficiency) is produced. It explores how individual principals understand their roles and ethics within those practices of audit emerging in school governance, and how their self-regulation is constituted through NAPLAN – the National Assessment Program, Literacy and Numeracy. A key effect of NAPLAN has been the rise of auditing practices that change how education is valued. Open-ended interviews with 13 primary and secondary school principals from Western Australia, South Australia and New South Wales asked how they perceived NAPLAN's impact on their work, their relationships within their school community and their ethical practice.

Reciprocating ball-on-flat dry sliding friction and wear experiments have been conducted on singlephase γ-Y2Si2O7 ceramic flats in contact with AISI 52100 bearing steel and Si3N4 ceramic balls at 5-15N normal loads in an ambient environment. The kinetic friction coefficients of γ-Y2Si2O7 varied in the range over 0.53-0.63 against AISI 52100 steel and between 0.51-0.56 against Si3N4 ceramic. We found thatwear occurred predominantly during the running-in period and it almost ceased at the steady friction stage. The wear rates of γ-Y2Si2O7 were in the order of 10-4mm3/(N m). Besides, wear debris strongly influenced the friction and wear processes. The strong chemical affinity between γ-Y2Si2O7 and AISI 52100 balls led to a thick transfer layer formed on both contact surfaces of the flat and counterpart ball, which changed the direct sliding between the ball and the flat into a shearing within the transfer layer. For the γ-Y2Si2O7/Si3N4 pair, a thin silica hydrate lubricant tribofilm presented above the compressed debris entrapped in the worn track and contact ball surface. This transfer layer and the tribofilm separated the sliding couple from direct contact and contributed to the low friction coefficient and wear rate.

This workshop aims at discussing alternative approaches to resolving the problem of health information fragmentation, partially resulting from difficulties of health complex systems to semantically interact at the information level. In principle, we challenge the current paradigm of keeping medical records where they were created and discuss an alternative approach in which an individual's health data can be maintained by new entities whose sole responsibility is the sustainability of individual-centric health records. In particular, we will discuss the unique characteristics of the European health information landscape. This workshop is also a business meeting of the IMIA Working Group on Health Record Banking.
