Project 2.7 Leveraging R&D Investment for the Australian built environment : Phase 2 Case Study Report Part 2 - Road Construction Safety

This report discusses findings of a case study into "Road Construction Safety" undertaken as a part of the retrospective analysis component of Sustainable Built Environment National Research Centre (SBEnrc) Project 2.7 Leveraging R&D investment for the Australian Built Environment. The Queensland Department of Transport and Main Roads (QTMR) has taken a leadership role in developing a safer working environment for road construction workers. In the past decades, a range of initiatives have been introduced to contribute to improved performance in this area. Several initiatives have been undertaken by QTMR as part of their overarching commitment to safety. Three such initiatives form the basis for this case study investigation, in order to better illustrate the nature of R&D investment and its impact on day-to-day operations and the supply chain. These are the development and implementation of: (i) the Mechanical Traffic Aid: (ii) the Thermal Imaging Camera; and (iii) the Trailer-based CCTV (camera). This case study should be read in conjunction with Part 1 of this suite of reports.

Producing solidarity : a settlement strategy of the Karen refugee community in Brisbane, Australia

This paper explores the link between experience and context. It places the lived experiences of Karen refugees during settlement in Brisbane, Australia within the socio-political context of Burma, or particularly the historical context of persecution. Two key events – the Wrist-tying Ceremony and the Karen New Year – provide a link between experience and context. The findings of this study show a community strategically at work in a new and ongoing settlement process. This process pays respect to the complexities of cultural integrity whilst also engaging with the challenges of integration. The complexities are local (in terms of cultural, linguistic and religious diversity), national (maintaining a broader sense of community that includes linkages across Australia, as well as an engagement with the Australian socio-political context), and transnational (participating in a global Karen community). This transnational community encompasses Karen settling elsewhere in the world, Karen in refugee camps neighbouring Burma, and Karen living inside Burma. This paper argues that substantial “identity work” is involved in Karen settlement. The two key community events are useful vignettes of this identity work. Both events demonstrate how Karen cultural practices can meaningfully negotiate deeply historical ideas of Karen identity with contemporary challenges of settlement. In addition, they set out a version of settlement that departs from traditional settlement constructs; they show how the lived experience of settlement is messy, complex and dynamic, and not reflective of the neat, idealistic models that immigration policy and settlement theory project.

Submission to the Legal Affairs and Community Safety Committee - Youth Justice (Boot Camp Orders) and Other Legislation Amendment Bill 2012

This submission addresses the Youth Justice (Boot Camp Orders) and Other Legislation Amendment Bill 2012 which has as its objectives (1) the introduction of a Boot Camp Order as an option instead of detention for young offenders and (2) the removal of the option of court referred youth justice conferencing for young offenders. As members of the QUT Faculty of Law Centre for Crime and Justice we welcome the invitation to participate in the discussion of these issues which are critically important to the Queensland community at large but especially to our young people.

Model development and dynamic load-sharing analysis of longitudinal-connected air suspensions

The objective of this research was to investigate the effect of suspension parameters on dynamic load-sharing of longitudinal-connected air suspensions of a tri-axle semi-trailer. A novel nonlinear model of a multi-axle semi-trailer with longitudinal-connected air suspension was formulated based on fluid mechanics and thermodynamics and was validated through test results. The effects of suspension parameters on dynamic load-sharing and road-friendliness of the semi-trailer were analyzed. Simulation results indicate that the road-friendliness metric DLC (Dynamic Load Coefficient), is generally in accordance with the load-sharing metric - DLSC (Dynamic Load Sharing Coefficient). When the static height or static pressure increases, the DLSC optimization ratio declines monotonically. The effect of employing larger air lines and connectors on the DLSC optimization ratio gives varying results as road roughness increases and as driving speed increases. The results also indicate that if the air line diameter is always assumed to be larger than the connector diameter, the influence of air line diameter on load-sharing is more significant than that of the connector.

The doctrine of command responsibility in the midst of war : legal fallacy or reflection of reality

The history of war is blighted with astonishing reminders of man’s ability to cast his sense of humanity aside and inflict unspeakable harm upon one another. The ruthless bombing of Dresden, the callousness of the Nazi concentration camps and the massacre of the Tutsis are but a few of the atrocities that have haunted our past. In response to these atrocities, society has imposed an ever-increasing number of laws and rules to regulate warfare. Amongst these is the doctrine of command responsibility. The doctrine of command responsibility states that a commander is criminally liable for the crimes of his subordinates if he knew or should have known of their crimes. This paper will examine whether the doctrine is an appropriate and realistic legal standard to hold commanders accountable to or whether the doctrine is more a reflection of social sentiment and legal rhetoric. If the doctrine, and indeed the law of war in general, is unrealistic then the law cannot fulfil its purpose - that is, the prevention of atrocities. Instead of being solely a reflection of moral authority and social sentiments the law must also be a tool that guides and shapes the decisions and actions of the military through the chaotic and brutal nature of war...

Effect of driving conditions and suspension parameters on dynamic load-sharing of longitudinal-connected air suspensions

The objective of this research was to investigate the effects of driving conditions and suspension parameters on dynamic load-sharing of longitudinal-connected air suspensions of a tri-axle semi-trailer. A novel nonlinear model of a multi-axle semi-trailer with longitudinal-connected air suspension was formulated based on fluid mechanics and thermodynamics and was validated through test results. The effects of driving conditions and suspension parameters on dynamic load-sharing and road-friendliness of the semi-trailer were analyzed. Simulation results indicate that the road-friendliness metric-DLC (dynamic load coefficient) is not always in accordance with the load-sharing metric-DLSC (dynamic load-sharing coefficient). The effect of employing larger air lines and connectors on the DLSC optimization ratio gives varying results as road roughness increases and as driving speed increases. When the vehicle load reduces, or the static pressure increases, the DLSC optimization ratio declines monotonically. The results also indicate that if the air line diameter is always assumed to be larger than the connector diameter, the influence of air line diameter on load-sharing is more significant than that of the connector.

A Literature Review of Wellness, Wellbeing and Quality of Life Issues as they impact upon the Australian Mining Sector

Australia’s mining boom Global demand for minerals and energy products has fuelled Australia’s recent resources boom and has led to the rapid expansion of mining projects not only in remote locations but increasingly in settled traditionally agricultural rural areas. A fundamental shift has also occurred in the provisioning of skilled and semi-skilled workers. The huge acceleration in industry demand for labour has been accompanied by the entrenchment of workforce arrangements largely dependent on fly-in, fly-out (FIFO) and drive–in, drive–out (DIDO) non-resident workers (NRWs). While NRWs are working away from their homes, they are usually accommodated in work camps or ‘villages’ for the duration of their work cycle which are normally comprised of many consecutive days of 12-hour day- and night-shifts. The health effects of this form of employment and the accompanying lifestyle is increasingly becoming contentious. Impacts on personal wellness, wellbeing and quality of life essentially remain under-researched and thus misunderstood. Sodexo in Australia Sodexo began operations in Australia in 1982, and has since become a leader in providing Quality of Life (QOL) services to businesses across the country. The 6,000 Australian employees are part of a global Sodexo team of 413,000 people. Sodexo in Australia designs, delivers and manages on-site their QOL services at 320 diverse site locations, including remote sites. Sodexo operates in a range of sectors, including the mining industry. Service plans are tailored to suit the individual needs of organisations. Sodexo Remote Sites has previously conducted unpublished research among mining workers in Australia. The results highlighted needs and expectations of Australian mining workers. Main insights about workers’ requirements were directed towards: • contacts with closest; • warm rest time around proper and varied meals; • additional services to help them better enjoy their life onsite and/or make the most of it; • organise their transportation; • promote community living; and • finding balance between professional and personal life. The brief for this current research is aimed at building upon this knowledge. Research brief Expectations for quality of life and wellness and wellbeing services are increasing dramatically. It's getting costlier and more difficult to retain valuable employees. This is particularly the case in the Australian mining sector. Given the level of interest in ensuring healthy workplaces in Australia, Sodexo has commissioned QUT to conduct a literature review. The objectives as specified by Sodexo are: Objective 1: To define the concepts of wellness and wellbeing and quality of life in Australia Objective 2: To examine how wellness and wellbeing are developed within organisations in Australia and how they impact on employee and organizational performance. More specifically, to review the literature that could be sourced about: • challenges of the mining environment; • the mining lifestyle – implications for health, wellness and daily life; • personal health and wellness of Australian mining workers; • factors affecting health in mines and perceived support for health and wellness; and • the impact of employer investment in health on perceptions and behaviour of employees. Objective 3: To determine what impact employee wellness and well-being has on the performance of mining workers. More specifically, to review the literature that could be sourced about: • impact of obesity, alcohol, tobacco use on companies; and • links between employee engagement and satisfaction and company productivity. Accordingly this review has attempted to ascertain what factors an organisation should focus on in order to reduce absenteeism and turnover and increase commitment, satisfaction, safety and productivity, with specific reference to the mining industry in Australia. The structure of the report aligns with the stated objectives in that each of the first three parts address an objective. Part IV summarises prominent issues that have arisen and offers some concluding observations and comments.

Submission : Proposed reforms to youth justice in Queensland

The proposed reforms to the youth justice system in Queensland are premised on the assumption that offending by young people is increasing. We noted (Carrington, Dwyer, Hutchinson and Richards 2012, 8) in a recent submission about the boot camps legislation that: "Statistics suggest that this concern is not warranted. Certainly studies show that ‘rates per 100,000 juveniles in detention in Queensland have been relatively stable compared with the national trend’ (Richards 2011) and that rates of detention of child offenders have declined generally in Australia over the last three decades. Youth offending statistics are affected by the diversion options used by the police, as well as by the numbers and levels of policing, and any special strategies such as Operation Colossus in the northern part of the state. ‘Community concern’ about crime does not always reflect the true rates of crime across Queensland. Policy should be based on valid evidence, not on ‘community concern’. With stable numbers of young people being detained in Australia, the research clearly suggests that youth offending is not escalating."...

The 1989 Comprehensive Plan of Action (CPA) and refugee policy in Southeast Asia : twenty years forward what has changed?

In 2012, the only South East Asian countries that have ratified the 1951 Convention relating to the Status of Refugees and the 1967 Protocol Relating to the Status of Refugees (hereafter referred to as the 1951 Convention and 1967 Protocol) is Philippines (signed 1954), Cambodia (signed 1995) and Timor Leste (signed 2001). Countries such as Indonesia, Malaysia and Thailand have annual asylum seeking populations from Myanmar, South Asia and Middle East, that are estimated to be at 15 000-20 000 per country (UNHCR 2012). The lack of a permanent and formal asylum processing process in these countries means that that asylum-seeking populations in the region are reliant on the local offices of the United Nations High Commission for Refugees based in the region to process their claims. These offices rely upon the good will of these governments to have a presence near detection camps and in capital cities to process claims of those who manage to reach the UNHCR representative office. The only burden sharing mechanism within the region primarily exists under the Bali Process on People Smuggling, Trafficking in Persons and Related Transnational Crime (the Bali Process), introduced in 2002. The Bali Process refers to an informal cooperative agreement amongst the states from the Asia-Pacific region, with Australia and Indonesia as the co-chairs, which discusses its namesake: primarily anti-people smuggling activities and migration protocols. There is no provision within this process to discuss the development of national asylum seeking legislation, processes for domestic processing of asylum claims or burden sharing in contrast to other regions such as Africa and South America (i.e. 2009 African Union Convention for the Protection and Assistance of the Internally Displaced, 1969 African Union Convention Governing the Specific Aspects of Refugee Problems in Africa and 1984 Cartagena Declaration on Refugees [Americas]) (PEF 2010: 19).

Submission to the Legal Affairs and Community Safety Committee Youth Justice and Other Legislation Amendment Bill

This submission addresses the Youth Justice and Other Legislation Amendment Bill 2014 the objectives of which are to: 1. Permit repeat offenders’ identifying information to be published and open the Children’s Court for youth justice matters involving repeat offenders; 2. Create a new offence where a child commits a further offence while on bail; 3. Permit childhood findings of guilt for which no conviction was recorded to be admissible in court when sentencing a person for an adult offence; 4. Provide for the automatic transfer from detention to adult corrective services facilities of 17 year olds who have six months or more left to serve in detention; 5. Provide that, in sentencing any adult or child for an offence punishable by imprisonment, the court must not have regard to any principle, whether under statute or at law, that a sentence of imprisonment (in the case of an adult) or detention (in the case of a child) should only be imposed as a last resort; 6. Allow children who have absconded from Sentenced Youth Boot Camps to be arrested and brought before a court for resentencing without first being given a warning; and 7. Make a technical amendment to the Youth Justice Act 1992.

Social Justice Impacts of the Resources Boom

Until the 1970s mining leases were issued by state governments subject to conditions that companies build or substantially finance local community infrastructure, including housing, streets, transport, schools, hospitals and recreation facilities. Townships and communities went hand in hand with mining development. However, in the past thirty years mining companies have moved progressively to an expeditionary strategy for natural resources extraction - operating a continuous production cycle of 12 hour shifts - increasingly reliant on non-resident, fly-in, fly-out or drive-in, drive-out (FIFO/DIDO) workers who typically work block rosters, reside in work camps adjacent to existing communities and travel large distances from their homes. This paper presents the key findings of our survey into the social impacts of this kind of mining development in Qld. Based on the results we argue that the social license to develop new mining projects is strong for projects requiring a 25% or less non-resident workforce, diminishes significantly thereafter and is very weak for projects planning to recruit a non-resident workforce in excess of 75%. This finding is significant because there are at least 67 new mining projects undergoing social impact assessment in Queensland, and many it appears are planning to hire significant proportions of non-resident workers. The paper considers the policy implications of this growing social justice issue concluding there is a clear need for national leadership in formulating a national policy framework for guiding socially responsible and sustainable mining development into the next millennium.

Youth off the Streets "Our Place, Walgett Youth and Young Families Project" Project Evaluation.

The Project: • YOTS is a major youth specific agency established in 1991. It is a non-denominational, non-discriminatory and not-for-profit organisation, providing a wide range of services and offering a full continuum of care. It seeks to build on the strengths and positive aspects of marginalised young people and communities. • The 'Our Place, Walgett Youth and Young Families Project' further develops an existing YOTS capacity to provide services to Aboriginal young people. • The project adopted an action-research and community development model in which YOTS worked in partnership with the Youth Sub-committee of the Walgett Interagency. • Specific goals/objectives of the program were to: Coordinate youth and young family activities in partnership with local services and the community to build self-esteem, pride, resilience, motivation and skills; Contribute to the prevention and reduction of homelessness, unstable and unsafe housing and disruptive mobility (Walgett/Redfern) in youth and young families; Increase and improve collaborative engagement between youth and family focused services; and, research, adapt and implement Australian and international best-practice homelessness prevention/reduction initiatives to contribute to new models of practice relevant to rural and regional areas. • The project centred around an out-reach model that focused on providing a safe space with relevant structured activities coordinated by YOTS youth and family workers. Through community and service provider consultation, it was proposed that local services could coordinate strategies and activities and run them, where possible, from the centre, providing ease of access in a safe and supportive context. • Specific activities included: Implementing regular meetings with the stakeholders and community representatives; Developing a Terms of Reference for YOTS presence in the Walgett community; Undertaking a community consultation prior to finalising program activities; Implementing a range of recreational activities (sports, music, arts and crafts) early on in the activity; Implementing young family support initiatives; implementing a volunteering program, including volunteer support to young families through intergenerational volunteering; running a series of Culture and Healing Camps in partnership with local Elders and other services; Running a series of Music Camps; Providing alternative education support and referrals in partnership with local schools; Researching, identifying and adapting other best-practice models.

An investigation into the effect of infrastructure on fly-in fly-out mining workers

Objective: To explore fly-in fly-out (FIFO) mining workers' attitudes towards the leisure time they spend in mining camps, the recreational and social aspects of mining camp culture, the camps' communal and recreational infrastructure and activities, and implications for health. Design: In-depth semistructured interviews. Setting: Individual interviews at locations convenient for each participant. Participants: A total of seven participants, one female and six males. The age group varied within 20–59 years. Marital status varied across participants. Main outcome measures: A qualitative approach was used to interview participants, with responses thematically analysed. Findings highlight how the recreational infrastructure and activities at mining camps impact participants' enjoyment of the camps and their feelings of community and social inclusion. Results: Three main areas of need were identified in the interviews, as follows: (i) on-site facilities and activities; (ii) the role of infrastructure in facilitating a sense of community; and (iii) barriers to social interaction. Conclusion: Recreational infrastructure and activities enhance the experience of FIFO workers at mining camps. The availability of quality recreational facilities helps promote social interaction, provides for greater social inclusion and improves the experience of mining camps for their temporary FIFO residents. The infrastructure also needs to allow for privacy and individual recreational activities, which participants identified as important emotional needs. Developing appropriate recreational infrastructure at mining camps would enhance social interactions among FIFO workers, improve their well-being and foster a sense of community. Introducing infrastructure to promote social and recreational activities could also reduce alcohol-related social exclusion.

Transport and health in China : recent collaborative research relating to vehicle factors and pollution

The nature of the transport system contributes to public health outcomes in a range of ways. The clearest contribution to public health is in the area of traffic crashes, because of their direct impact on individual death and disability and their direct costs to the health system. Other papers in this conference address these issues. This paper outlines some collaborative research between the Centre for Accident Research and Road Safety - Queensland (CARRS-Q) at QUT and Chinese researchers in areas that have indirect health impacts. Heavy vehicle dynamics: The integrity of the road surface influences crash risk, with ruts, pot-holes and other forms of road damage contributing to increased crash risks. The great majority of damage to the road surface from vehicles is caused by heavy trucks and buses, rather than cars or smaller vehicles. In some cases this damage is due to deliberate overloading, but in other cases it is due to vehicle suspension characteristics that lead to occasional high loads on particular wheels. Together with a visiting researcher and his colleagues, we have used both Queensland and Chinese data to model vehicle suspension systems that reduce the level of load, and hence the level of road damage and resulting crash risk(1-5). Toll worker exposure to vehicle emissions: The increasing construction of highways in China has also involved construction of a large number of toll roads. Tollbooth workers are potentially exposed to high levels of pollutants from vehicles, however the extent of this exposure and how it relates to standards for exposure are not well known. In a study led by a visiting researcher, we conducted a study to model these levels of exposure for a tollbooth in China(6). Noise pollution: The increasing presence of high speed roads in China has contributed to an increase in noise levels. In this collaborative study we modelled noise levels associated with a freeway widening near a university campus, and measures to reduce the noise(7). Along with these areas of research, there are many other areas of transport with health implications that are worthy of exploration. Traffic, noise and pollution contribute to a difficult environment for pedestrians, especially in an ageing society where there are health benefits to increasing physical activity. By building on collaborations such as those outlined, there is potential for a contribution to improved public health by addressing transport issues such as vehicle factors and pollution, and extending the research to other areas of travel activity. 1.

Hydraulic conductivity fields: Gaussian or not?

Hydraulic conductivity (K) fields are used to parameterize groundwater flow and transport models. Numerical simulations require a detailed representation of the K field, synthesized to interpolate between available data. Several recent studies introduced high-resolution K data (HRK) at the Macro Dispersion Experiment (MADE) site, and used ground-penetrating radar (GPR) to delineate the main structural features of the aquifer. This paper describes a statistical analysis of these data, and the implications for K field modeling in alluvial aquifers. Two striking observations have emerged from this analysis. The first is that a simple fractional difference filter can have a profound effect on data histograms, organizing non-Gaussian ln K data into a coherent distribution. The second is that using GPR facies allows us to reproduce the significantly non-Gaussian shape seen in real HRK data profiles, using a simulated Gaussian ln K field in each facies. This illuminates a current controversy in the literature, between those who favor Gaussian ln K models, and those who observe non-Gaussian ln K fields. Both camps are correct, but at different scales.
