Development of a digital material representation (DMR) model of dual phase steel is presented within the paper. Subsequent stages involving generation of a reliable representation of microstructure morphology, assignment of material properties to component phases and incorporation of the model into the commercial finite element software are described within the paper. Different approaches used to recreate dual phase morphology in a digital manner are critically assessed. However, particular attention is placed on innovative identification of phase properties at the micro scale by using micro-pillar compression tests. The developed DMR model is finally applied to model influence of micro scale features on failure initiation and propagation under loading conditions.

The Immigration Museum Melbourne, Australia, launched the Identity: Yours, Mine, Ours exhibition in 2011. Aimed primarily at secondary school students, this long-term installation seeks to foster reflection on identity and belonging, as well as dialogue about racism, through an interactive, immersive museum experience. This paper describes a multi-method research project, which included narrative interviews, focus groups and video diaries with 47 Year 11–12 students from three secondary schools in Victoria, Australia, and discusses each method's contribution to an overall empirical understanding of the installation's impact on students' experiences. Emerging findings suggest the ways in which the exhibition space supports students to encounter and engage with individual stories and experiences, thus moving beyond an abstract tolerance of cultural diversity by unsettling the self and destabilising stereotyped and prejudiced interpretations of the ‘other’. The paper concludes by discussing the potential for triangulated qualitative approaches to provide rich emic perspectives on multi-sensory exhibitions.

Hanif Kureishi: Contemporary Critical Perspectives brings together leading scholars of contemporary British fiction and culture to reassess the full range of the author's writings, from novels such as The Black Album, My Son the Fanatic and Something to Tell You to films such as Sammy and Rosie Get Laid, My Son the Fanatic and Venus. As well as exploring Kureishi's handling of such themes as Thatcherism, terrorism, race, class and sexuality, the book move moves beyond sociological and psychoanalytical approaches, examining the stylistic features of his most recent novel, The Last Word. The volume includes interviews with Stephen Frears, the director of My Beautiful Launderette, and with Hanif Kureishi himself, as well as a foreword by Roger Michell, who has directed several of the author's screenplays, most recently Le Week-End.

This article offers a new approach for examining Muslim women in sport, which combines the domains of sporting participation, consumption and representation. It proposes moving beyond a sports development paradigm and deficit model of sports participation, whereby marginal communities are incorporated into the mainstream by playing sport, to take account of other ways that people engage with sport as consumers and fans. Conceptually, this approach is informed by transnational feminist perspectives, which foreground the role of power hierarchies in the production of knowledge about the sporting female Other. It suggests that sport practitioners, scholars and policy makers pay greater theoretical attention to how Muslim women are constructed within sport discourses. By widening the research focus to consider consumption and representation, possibilities emerge to expand on the narrow research and policy fields of ‘ethnicity’ and ‘well-being’ focused on physical health outcomes through which Muslim women’s engagement with sport is commonly framed.

The direct approach in designing functional observers was first presented in [1] for estimating a single function of the states of a Linear Time-Invariant (LTI) system. One of the benefits of the direct scheme is that it does not require solving the interconnected Sylvester equations that appear in the other observer design approaches. In the present paper, the direct approach is extended to reconstruct multiple functions of the states in such a way that the minimum possible order of the observer is achieved. The observer is designed so that an asymptotic functional observer can be obtained with arbitrary convergence rate. In the proposed methodology, it is not necessary that a reduced order observer exists for the desired functions to be estimated. To release this limitation, an algorithm is employed to find some auxiliary functions in the minimum required number to be appended to the desired functions. This method assumes that the system is functional observable. This assumption however is less restrictive than the observability and detectability conditions of the system. A numerical example and simulation results explain the efficacy and the benefits of the proposed algorithm.

This study aimed to highlight the praxis of various mainstream and alternative faith traditions in Australia with relation to environmental sustainability issues. A mixed methods approach (surveys, interviews, site visits) was used to investigate the levels of awareness and involvement of faith communities on issues including biodiversity protection, water conservation, energy efficiency, waste management and cultural property heritage. The aim of this chapter is to highlight a theme of integration (or lack thereof) that arose out of the interviews which formed a critical part of the participants’ worldview. A brief overview of the relationships of attitudes and behaviours to environmental issues and the importance placed on values and worldviews is provided. Individuals from 40 faith groups participated in the study; in this chapter, individuals and case studies from ten different groups are highlighted. These range from the conventional, mainstream Christian traditions to alternative Christian and Eastern traditions as well as the new age movement. The study found that mainstream traditions were making important attempts at integrating their worldview into appropriate environmental management strategies; however, the impact was marginal overall. The lesser known and alternative traditions, however, were at a significant leading edge of integrating praxis; yet, because these traditions are viewed with an element of suspicion, their efforts were marginalized by members of other faiths and the public. Thus, there are several points of convergence and divergence that faith traditions have with regard to environmental sustainability.

Energy crisis is one of the major problems facing the progress of human society. There are several energy-efficient technologies that can be applied to save energy and make a sustainable environment. Passive air cooling of earth pipe cooling technology is one of them to reduce the energy consumption for hot and humid subtropical climates. The technology works with a long buried pipe with one end for intake air and the other end for providing air cooled by soil to the desired space such as residential, agricultural, or industrial buildings. It can be an attractive economical alternative to conventional cooling since there are no compressors or any customary mechanical unit. This chapter reports the performance of a vertical earth pipe cooling system for a hot and humid subtropical climatic zone in Queensland, Australia. A series of buried pipes were installed in vertical arrangement in order to increase earth pipe cooling performance. To measure the performance of the system, a numerical model was developed and simulated using the CFD software Fluent in ANSYS 15.0. Data were collected from two modeled rooms built from two shipping containers and installed at the Sustainable Precinct at Central Queensland University, Rockhampton, Australia. The impact of air temperature and velocity on room cooling performance has also been assessed. A temperature reduction of 1.82 °C was observed in the room connected to the vertical earth pipe cooling system, which will save the energy cost for thermal cooling in buildings.

This research aims to understand the attitudes and behaviours of stakeholders towards waste management and consequently identify ways of improving waste management practices in construction projects. Semi-structured interviews were conducted. The findings reveal that most of the decisions in construction projects are based on their financial returns unless there is a special requirement to comply with Green Star or any other sustainable building rating system. Even though there is a trend towards environment-friendly construction, contractors are favourable towards methods involving financial incentives. Results also indicate that private developers are more price-driven compared with government clients. Findings reveal the necessity of enforcing legislation to improve waste management practices until such practices become culturally embedded in organizations across the supply chain. Similarly, end users' motivation towards waste management was also identified as a key to encouraging stakeholders of construction projects and improving their attitudes and behaviours towards waste management practices.

BACKGROUND: Despite the rapid growth in the sophistication of research on bipolar disorder (BD), the field faces challenges in improving quality of life (QoL) and symptom outcomes, adapting treatments for marginalized communities, and disseminating research insights into real-world practice. Community-based participatory research (CBPR)-research that is conducted as a partnership between researchers and community members-has helped address similar gaps in other health conditions. This paper aims to improve awareness of the potential benefits of CBPR in BD research. METHODS: This paper is a product of the International Society for Bipolar Disorders (ISBD) Taskforce on Community Engagement which includes academic researchers, healthcare providers, people with lived experience of BD, and stakeholders from BD community agencies. Illustrative examples of CBPR in action are provided from two established centres that specialize in community engagement in BD research: the Collaborative RESearch Team to study psychosocial issues in BD (CREST.BD) in Canada, and the Spectrum Centre for Mental Health Research in the United Kingdom. RESULTS AND DISCUSSION: We describe the philosophy of CBPR and then introduce four core research areas the BD community has prioritized for research: new treatment approaches, more comprehensive outcome assessments, tackling stigma, and enhanced understanding of positive outcomes. We then describe ways in which CBPR is ideal for advancing each of these research areas and provide specific examples of ways that CBPR has already been successfully applied in these areas. We end by noting potential challenges and mitigation strategies in the application of CBPR in BD research. CONCLUSIONS: We believe that CBPR approaches have significant potential value for the BD research community. The observations and concerns of people with BD, their family members, and supports clearly represent a rich source of information. CBPR approaches provide a collaborative, equitable, empowering orientation to research that builds on the diversity of strengths amongst community stakeholders. Despite the potential merits of this approach, CBPR is as yet not widely used in the BD research field, representing a missed opportunity.

One of the areas of concern raised by cross-border reproductive travelregards the treatment of women who are solicited to provide their ova orsurrogacy services to foreign consumers. This is particularly troublesome inthe context of developing countries where endemic poverty and low standardsfor both medical care and informed consent may place these womenat risk of exploitation and harm. We explore two contrasting proposals forpolicy development regarding the industry, both of which seek to promoteethical outcomes and social justice: While one proposal advocates efforts tominimize cross-border demand for female reproductive resources throughthe pursuit of national self-sufficiency, the other defends cross-border tradeas a means for meeting the needs of vulnerable groups. Despite theconflicting objectives of the proposed strategies, the paper identifiescommon values and points of agreement between the two, including theimportance of regulations to safeguard those providing ova or surrogacyservices.

This paper provides a review of recent developments in population-based approaches to community health and explores the origins of the population health concept and its implications for the operation of health service management. There is a growing perception among health professionals that the key to improving health outcomes will be the implementation of integrated and preventive population-based resource management rather than investment in systems that respond to crises and health problems at the acute end of the service provision spectrum only. That is, we will need increasingly to skew our community health and welfare investments towards preventive care, education, lifestyle change, self-management and environmental improvement if we are to reduce the rate of growth in the incidence of chronic disease and mitigate the impact of these diseases upon the acute health care system. While resources will still need to be devoted to the treatment and management of physical trauma, infectious diseases, inherited illness and chronic conditions, it is suggested we could reduce the rate at which demand for these services is increasing at present by managing our environment and communities better, and through the implementation of more effective early intervention programs across particular population groups. Such approaches are known generally as population health management, as opposed to individual or illness - based health management' or even public health - and suggest that health systems might productively focus in the future on population level causation and not just upon disease-specific problems or illness management after the fact. Population health approaches attempt to broaden our understanding of causation and manage health through an emphasis on the health of whole populations and by building healthy communities rather than seeing "health care" as predominantly about illness management or responses to health crises. The concept also presupposes the existence of cleaner and healthier environments, clean water and food, and the existence of vibrant social contexts in which individuals are able to work for the overall good of communities and, ultimately, of each other.

In Australia, statutory construction adjudication is a fast payment dispute resolution process designed to keep the cash flowing down the hierarchical contractual chain in construction projects. Its rapid, highly regulatory and temporarily binding nature have led to it being often described as a ‘quick and dirty’ process that delivers ‘rough and ready’ justice. Adjudicators often have to grapple with complex legal issues related to jurisdictional facts and interpretation of contract provisions, though the majority of them are not legally trained. This has often led to a poor quality of adjudication outcome for large and complex payment claims which has, in turn, led to a mounting dissatisfaction due to the many judicial challenges to adjudicators’ determinations seen in recent years. The evolving tension between the object of the security of payment legislation and excessive involvement of the courts has often been the subject of comment by the judiciary. This paper aims to examine the legislative and judicial approaches to support the object of the security of payment legislation to ease cash flow. The paper adopts a desktop study approach whereby evidence is gathered from three primary sources – judicial decisions, academic publications and governmental reports. The paper concludes that there is a need to adopt other measures which can provide more convenient relief to aggrieved parties to an adjudication process, such that the adjudication process is kept away from the courts as far as is possible. Specifically, it is proposed that a well-designed expanded legislative review scheme of allegedly flawed adjudication, based on that provided in the Western Australian legislation, might stand as a promising remedy to eliminate the evolving tension.

OBJECTIVES: This study investigated the extent that psychosocial job stressors had lasting effects on a scaled measure of mental health. We applied econometric approaches to a longitudinal cohort to: (1) control for unmeasured individual effects; (2) assess the role of prior (lagged) exposures of job stressors on mental health and (3) the persistence of mental health.

METHODS: We used a panel study with 13 annual waves and applied fixed-effects, first-difference and fixed-effects Arellano-Bond models. The Short Form 36 (SF-36) Mental Health Component Summary score was the outcome variable and the key exposures included: job control, job demands, job insecurity and fairness of pay.

RESULTS: Results from the Arellano-Bond models suggest that greater fairness of pay (β-coefficient 0.34, 95% CI 0.23 to 0.45), job control (β-coefficient 0.15, 95% CI 0.10 to 0.20) and job security (β-coefficient 0.37, 95% CI 0.32 to 0.42) were contemporaneously associated with better mental health. Similar results were found for the fixed-effects and first-difference models. The Arellano-Bond model also showed persistent effects of individual mental health, whereby individuals' previous reports of mental health were related to their reporting in subsequent waves. The estimated long-run impact of job demands on mental health increased after accounting for time-related dynamics, while there were more minimal impacts for the other job stressor variables.

CONCLUSIONS: Our results showed that the majority of the effects of psychosocial job stressors on a scaled measure of mental health are contemporaneous except for job demands where accounting for the lagged dynamics was important.

This issue of Settler Colonial Studies comes out of a long-term collaboration between the guest editors which began, in earnest, with a panel on the theme of ‘Other People’s Country: Law, Water, Entitlement’ at the Cultural Studies Association of Australasia conference held at the University of Sydney in December 2012. The panel’s topic was drawn from our own work on encounters between settler and indigenous ‘laws’ over specific waters, including Lake Omapere in the Hokianga district of Aotearoa/New Zealand, Lake Okanagan in British Columbia, Canada, Lake Cayuga in upper New York State, and the Wenlock, Archer, Stewart and Lockhart rivers in far north Queensland, Australia.1 Further, the conference’s provocative title (Materialities: Economies, Empiricism, & Things) corresponded to our own interest in thinking through the entangled objects of law – legislation, policies, institutions, treaties and so on – that ‘govern’ waters and that make bodies of water ‘lawful’ within these settler colonial sites today. Informed by the theoretical interventions of cosmopolitics and political ecology, each opening up new approaches to questions of politics and ‘the political’, we were interested in attempting to locate these insights within material settler colonial ‘places’ rather than abstract structures of domination. A claim to water is not simply a claim to a resource. It is a claim to knowledge and to the constitution of place and therefore, in the terms of Isabelle Stengers, to the continued constitution of the past, present and future of a ‘real world’.
