Implementation of an integrated, technology-based, discovery mode assessment item involving an incubation period to enhance learning outcomes for engineering maths students

In this paper we discuss our current efforts to develop and implement an exploratory, discovery mode assessment item into the total learning and assessment profile for a target group of about 100 second level engineering mathematics students. The assessment item under development is composed of 2 parts, namely, a set of "pre-lab" homework problems (which focus on relevant prior mathematical knowledge, concepts and skills), and complementary computing laboratory exercises which are undertaken within a fixed (1 hour) time frame. In particular, the computing exercises exploit the algebraic manipulation and visualisation capabilities of the symbolic algebra package MAPLE, with the aim of promoting understanding of certain mathematical concepts and skills via visual and intuitive reasoning, rather than a formal or rigorous approach. The assessment task we are developing is aimed at providing students with a significant learning experience, in addition to providing feedback on their individual knowledge and skills. To this end, a noteworthy feature of the scheme is that marks awarded for the laboratory work are primarily based on the extent to which reflective, critical thinking is demonstrated, rather than the amount of CBE-style tasks completed by the student within the allowed time. With regard to student learning outcomes, a novel and potentially critical feature of our scheme is that the assessment task is designed to be intimately linked to the overall course content, in that it aims to introduce important concepts and skills (via individual student exploration) which will be revisited somewhat later in the pedagogically more restrictive formal lecture component of the course (typically a large group plenary format). Furthermore, the time delay involved, or "incubation period", is also a deliberate design feature: it is intended to allow students the opportunity to undergo potentially important internal re-adjustments in their understanding, before being exposed to lectures on related course content which are invariably delivered in a more condensed, formal and mathematically rigorous manner. In our presentation, we will discuss in more detail our motivation and rationale for trailing such a scheme for the targeted student group. Some of the advantages and disadvantages of our approach (as we perceived them at the initial stages) will also be enumerated. In a companion paper, the theoretical framework for our approach will be more fully elaborated, and measures of student learning outcomes (as obtained from eg. student provided feedback) will be discussed.

Truck overloading study in developing countries and strategies to minimize its impact

Overloading truck traffic is an untenable problem around the world. The occurrence of overloaded truck traffic can be evidence of rapid development of an economy. Most of the developing countries emphasize the development of economy, thus supporting reform of infrastructure is limited. This research investigates the relationship between truck overloading and the condition of road damage. The objective of this research is to determine the amount of economic loss due to overloaded truck traffic is. Axle load will be used to calculate the total ESAL to pavement. This study intends to provide perspective on the relationship between change in axle load due to overloading and the resultant service life of pavement. It can then be used in the estimation of pavement damage in other developing countries facing the problem of truck overloading. In conclusion, economical loss was found, which include reduction of pavement life and increase in maintenance and rehabilitation (M&R) cost. As a result, net present value (NPV) of pavement investment with overloading truck traffic is higher than normal truck traffic.

Overloading truck traffic study and strategy to minimise it

Overloaded truck traffic is a significant problem on highways around the world. Developing countries in particular, overloaded truck traffic causes large amounts of unexpected expenditure in terms of road maintenance because of premature pavement damage. Overloaded truck traffic is a common phenomenon in developing countries, because of inefficient road management and monitoring systems. According to the available literature, many developing countries are facing the same problem, which is economic loss caused by the existence of overloaded trucks in the traffic stream. This paper summarizes the available literature, news reports, journal articles and traffic research regarding overloaded traffic. It examines the issue of overloading and the strategies and legislation used in developed countries.

The Torrent : Toowoomba and the Lockyer Valley, 10 January 2011

Of all the stories to emerge from Queensland’s catastrophic summer of 2011, the most dramatic and starkly tragic were those that took place in Toowoomba and the Lockyer Valley. On January 10, 2011, after weeks of heavy rain and as floodwaters began to overwhelm much of south-east Queensland, an ‘inland tsunami’ hit the city of Toowoomba, the rural districts of Spring Bluff and Postmans Ridge, and the towns of Murphys Creek, Withcott, Helidon, and Grantham. The Torrent:Toowoomba and the Lockyer Valley, 10 January 2011 tells, for the first time, the extraordinary stories of survival and loss that emerged from that terrible day. Official figures state that twenty-four people died. Many escaped death only because they were rescued by members of the community or through sheer good fortune. Based on exclusive interviews with survivors, rescuers and with the families and friends of victims of the disaster, The Torrent is a unique and powerful account of human courage in the face of the devastating force of nature, and the enduring resilience of ordinary Australians.

Amanda Gearing Queensland Flood Collection 2011-2012

A collection of oral history recordings, photographs, hand drawn maps, videos and speech notes relating to the 2011 Queensland floods and the major flood event that occurred in Toowoomba and the Lockyer Valley region on 10 January 2011: a flash flood (described as an 'inland tsunami') which devastatingly took 21 human lives. The collection, amassed by Toowoomba-based journalist Amanda Gearing for her Master of Arts degree, includes 86 oral history recordings of flood survivors and rescuers in Spring Bluff, Murphys Creek, Toowoomba, Withcott, Postmans Ridge, Helidon, Carpendale and Grantham as well as digital photographs and videos taken by a number of those interviewed including those taken by Amanda Gearing and other locals. The interviews are very personal and powerful recollections of the experience of the flood event. Some recall feelings of fear and despair and tell of trauma and loss which continues well after the flood event. All are stories of resilience and hope, of rebuilding lives, of lessons learnt, and recommendations in order to avoid the same devastating results in future disasters.

OHS Regulation for a Changing World of Work

This volume assesses the legacy of the Robens Report, the intellectual foundation of modern OHS law and practice in Australia and many other countries, following the Report’s 30th anniversary. The authors confront the challenges facing OHS regulators and stakeholders in a new and different world dominated by service industries and globalisation rather than manufacturing industries and protection. They explore new models of OHS regulation that take account of gaps and deficiencies in the current arrangements. The authors bring international expertise from the United Kingdom, New Zealand and Scandinavia as well as Australia. They focus on the kinds of regulatory strategies, including both OHS law and enforcement policy, that are most likely to produce good OHS outcomes in this changing world of work. Particular topics examined are: The type, mix, content and coverage of OHS standards, Systematic OHS management and the development of organisational capability, Strategies for effective worker participation and representation, Models for achieving small business compliance, Regulatory responses to changes in work organisation, Responsive enforcement and adapted inspection, and Restorative justice.

Work Health and Safety Law and Policy

The third edition of Work Health and Safety Law and Policy continues to provide a plain English approach to explaining and analysing the law which regulates work health and safety in Australia. Providing broad coverage, this book focuses on the role that legal regulation plays in preventing work-related injury and disease, as well as the way in which the law contributes to rehabilitating and compensating injured and ill workers. This third edition focuses on the national model Work Health and Safety Bill 2009. The provisions of the model Bill are outlined, along with court decisions and other documentation that help interpret the provisions in new legislation enacting the model Bill. There is also a chapter in the book examining the national model Work Health and Safety Regulations 2011, and model codes of practice. The book includes three chapters on common law, statutory workers’ compensation provisions and rehabilitation. Tables summarising the key legal provisions of the major Australian Commonwealth, State and Territory workers’ compensation statutes have been updated and give quick and easy reference to points of legislation.

Rethinking OHS Enforcement

The relationship between 'reasonably practicable'and risk management regulation

This paper examines two concepts which are central to contemporary standard setting in occupational health and safety (OHS) regulation, and explores the differences and similarities between these concepts – the notion of ‘reasonably practicable’ which qualifies the ‘general duties’ and some other provisions in the Australian OHS standards, and the risk management requirements typically found in OHS regulations and approved codes of practice (advisory standards in Queensland).

Enforcing upstream: Australian health and safety inspectors and upstream duty holders

The ‘new style’ occupational health and safety legislation implemented in Australia from the late 1970s changed the character of OHS legal obligations, establishing general duties supported by process, performance and, more rarely, specification standards,1 and extending obligations to those who propagate risks as designers, manufacturers, importers or suppliers — the ‘upstream duty holders’. This article examines how OHS agencies inspect and enforce OHS legislation upstream, drawing on empirical research in four Australian states and relevant case law. We argue that upstream duty holders are an increasing area of attention for OHS inspectorates but these inspectorates have not yet risen to the challenge of harnessing these parties to help stem, at the source, the flow of risks into workplaces.

Infringement notices: stimulus for prevention or trivialising offences?

In the OHS field increasing use is being made of administrative penalties to enforce OHS legislation. Infringement notices (also known as penalty notices or on-the-spot fines) are used in several Australian jurisdictions and there are plans to introduce them in others. Overseas jurisdictions with some form of OHS administrative penalty include the United States, some Canadian provinces, and the system recently enacted in New Zealand. This article reviews empirical evidence and legal arguments about the use of infringement notices for enforcing OHS legislation. Key factors influencing the impact of these notices are discussed, including the monetary amounts of penalties, the nature of offences, the criteria and processes for issuing notices, and other implementation issues. There is a need for further empirical studies to determine the characteristics of infringement notice schemes that are most effective in motivating preventive action.

Qld flood inquest : ‘I could see his arms moving, he was trying to swim’

"Despite the 10 months of grieving for those lost in Queensland’s January floods, new evidence produced during the coronial inquest into the 22 deaths and three disappearances has revealed new shocks for the bereaved families. Brisbane Coroner’s Court yesterday was introduced to a series of high-tech Google Earth animations backed by funereal music, explaining the scope of the unfolding tragedy, which swept away husbands, wives, children and grandparents in less than three hours on the afternoon of January 10 this year. The court was also told of the extensive search for human remains, of 131 kilometres of creeks and rivers from Spring Bluff to Brisbane and hundreds of dams that were searched three times by police divers, 250 army personnel and 200 police."

Book Review: "Safe Design and Construction of Machinery – Regulation, Practice and Performance [First edition]"

With Safe Design and Construction of Machinery, the author presents the results of empirical studies into this significant aspect of safety science in a very readable, well-structured format. The book contains 436 references, 17 tables, one figure and a comprehensive index. Liz Bluff addresses a complex and important, but often neglected domain in OHS – the safety of machinery – in a holistic and profound, yet evidence based analysis; with many applied cases from her studies, which make the book accessible and a pleasant lecture. Although research that led to this remarkable publication might have been primarily focused on the regulators, this book can be highly recommended to all OHS academics and practitioners. It provides an important contribution to the body of knowledge in OHS, and establishes one of the few Australian in-depth insights into the significance of machinery producers, rather than machinery users in the wider framework of risk management. The author bases this fresh perspective on the well-established European Machinery Safety guidelines, and grounds her mixed-methods research predominantly in qualitative analysis of motivation and knowledge, which eventually leads to specific safety outcomes. It should be noted that both European and Australian legal aspects are investigated and considered, as both equally apply to many machinery exporters. A detailed description of the research design and methods can be found in an appendix. Overall, the unique combination of quantitative safety performance data and qualitative analysis of safety behaviours form a valuable addition to the understanding of machinery safety. The author must be congratulated on making these complex relationships transparent to the reader through her meticulous inquiry.
