She'll be right mate : inclusivity experiences of men and women working in projects

Occupational segregation is a major source of labour market rigidity and economic inefficiency due to a waste of human resources. Organisations are repeatedly recognised as gendered constructs exhibiting sustained work segregation, income and status inequality, as well as cultural and individual images of gender, and these are perpetuated through their processes, practices and pressures (Acker, 1990). A large percentage of Australia’s workforce is now employed in project-based or project-oriented organisations, leading to the claim that Australia is a project-based economy. For a continued strong performance in this economy, organisations that employ project personnel will need to consider how they address inclusivity and equality in diversity in project based temporary organisations to ensure the supply of high quality project professionals into the future. This paper investigates the inclusion processes experienced and exercised by men and women working in temporary organisations in project situations through a review of reports on the inclusion processes experienced by 60 project managers and project workers in three project based industries in Australia. Results indicate that temporary organisations are not implementing equality and diversity management strategies at the macro level and project workers are accepting this lack of recognition. However inclusivity and equality at the micro level of the team is seen as vital.

CFD simulations of flow and heat transfer through the porous interface of a metal foam heat exchanger

This paper offers numerical modelling of a waste heat recovery system. A thin layer of metal foam is attached to a cold plate to absorb heat from hot gases leaving the system. The heat transferred from the exhaust gas is then transferred to a cold liquid flowing in a secondary loop. Two different foam PPI (Pores Per Inch) values are examined over a range of fluid velocities. Numerical results are then compared to both experimental data and theoretical results available in the literature. Challenges in getting the simulation results to match those of the experiments are addressed and discussed in detail. In particular, interface boundary conditions specified between a porous layer and a fluid layer are investigated. While physically one expects much lower fluid velocity in the pores compared to that of free flow, capturing this sharp gradient at the interface can add to the difficulties of numerical simulation. The existing models in the literature are modified by considering the pressure gradient inside and outside the foam. Comparisons against the numerical modelling are presented. Finally, based on experimentally-validated numerical results, thermo-hydraulic performance of foam heat exchangers as waste heat recovery units is discussed with the main goal of reducing the excess pressure drop and maximising the amount of heat that can be recovered from the hot gas stream.

Reducing bubble defect on the outsole production process in the footwear manufacturing industry

The purpose of this study is to discover the significant factors causing the bubble defect on the outsoles manufactured by the Case Company. The bubble defect occurs approximately 1.5 per cent of the time or in 36 pairs per day. To understand this problem, experimental studies are undertaken to identify various factors such as injector temperature, mould temperature; that affects the production of waste. The work presented in this paper comprises a review of the relevant literature on the Six Sigma DMAIC improvement process, quality control tools, and the design of the experiments. After the experimentation following the Six Sigma process, the results showed that the defect occurred in approximately 0.5 per cent of the products or in 12 pairs per day; this decreased the production cost from 6,120 AUD per month to 2,040 AUD per month. This research aimed to reduce the amount of waste in men’s flat outsoles. Hence, the outcome of research presented in this paper should be used as a guide for applying the appropriate process for each type of outsole.

Desalination of seawater using solar, ambient energy and waste heat from air conditioning

Desalination is considered one of the most suitable areas for the utilization of solar energy, as there are many places in the world where abundant supply of solar energy is available and also there is a great demand for fresh water. An integrated solar heat pump desalination system has been developed at the National University of Singapore. The system also offers the opportunity of water heating and drying utilizing solar, ambient energy and waste heat from air conditioning system, which is conventionally dumped into the environment causing global warming. Desalination is carried out by making use of a single effect of Multi-Effect Distillation (MED) system. Within the desalination chamber, both fl ashing and evaporation of saline water take place. The maximum Coefficient of Performance (COP) of the heat pump system was around 5.8. In the integrated system, the maximum fresh water production rate was 9.6 l h−1 and a Performance Ratio (PR) of 1.2. For only desalination, the system has the potential to produce a maximum of 30 l h−1 of fresh water.

Greenhouse gas emissions in livestock production systems

Agriculture is responsible for a significant proportion of total anthropogenic greenhouse gas emissions (perhaps 18% globally), and therefore has the potential to contribute to efforts to reduce emissions as a means of minimising the risk of dangerous climate change. The largest contributions to emissions are attributed to ruminant methane production and nitrous oxide from animal waste and fertilised soils. Further, livestock, including ruminants, are an important component of global and Australian food production and there is a growing demand for animal protein sources. At the same time as governments and the community strengthen objectives to reduce greenhouse gas emissions, there are growing concerns about global food security. This paper provides an overview of a number of options for reducing methane and nitrous oxide emissions from ruminant production systems in Australia, while maintaining productivity to contribute to both objectives. Options include strategies for feed modification, animal breeding and herd management, rumen manipulation and animal waste and fertiliser management. Using currently available strategies, some reductions in emissions can be achieved, but practical commercially available techniques for significant reductions in methane emissions, particularly from extensive livestock production systems, will require greater time and resource investment. Decreases in the levels of emissions from these ruminant systems (i.e., the amount of emissions per unit of product such as meat) have already been achieved. However, the technology has not yet been developed for eliminating production of methane from the rumen of cattle and sheep digesting the cellulose and lignin-rich grasses that make up a large part of the diet of animals grazing natural pastures, particularly in arid and semi-arid grazing lands. Nevertheless, the abatement that can be achieved will contribute significantly towards reaching greenhouse gas emissions reduction targets and research will achieve further advances.

Waste generations and efficiency measures in Japan

This study measures the efficiencies incorporating waste generation using Japanese prefecture level data. We apply and compare several models using directional distance functions. There are wide variations in the efficiency scores between the two orientations, "input, desirable and undesirable output orientation" and "undesirable output orientation". However, the difference in abatement factor does not result in wide variations in the efficiency scores. Our results show that there are wide differences in the efficiency scores among prefectures. © 2012 Springer.

Effectiveness of policy against illegal disposal of waste

Our objective is to analyze the effectiveness, against the illegal disposal of waste, of a licensing system that has been introduced in a waste management policy. We theoretically find enforcement leverage in the licensing system, and then examine the theoretical result empirically. The results suggest that extending liability to disposers, which forms the basis of the enforcement leverage, deters illegal disposal more effectively than increasing penalties for illegal disposal. We also obtain evidence of transboundary movement of illegal disposal, and find how the court determines penalties for illegal disposal.

Food talks back : Exploring the role of mobile applications in reducing domestic food wastage

Mitigating domestic food waste reduces its environmental and economic impacts. In our study, we have identified the use of mobile technology to support behaviour change as a key tool to assist the process of reducing food waste. This paper reports on three mobile applications designed to reduce domestic food waste: Fridge Pal, LeftoverSwap and EatChaFood. The paper examines how each app can influence consumer knowledge of domestic food supply, location, and literacy. We discuss our findings with respect to three considerations: (i) assisting with the user’s food supply and location knowledge; (ii) improving the user’s food literacy; (iii) facilitating social food sharing of excess food. We present new insights for mobile interventions that encourage changes towards more sustainable behaviours to reduce food waste.

Online Copyright Infringement Discussion Paper July 2014

The Paper, by consideration of the issue of authorisation, addresses a very practical development in commerce. Online copyright infringement is now not only about unauthorised uses of cinematograph films but has filtered down to become more prevalent amongst small to medium enterprises (SME), as some competitors embrace online trading by aggressively and often unlawfully, seeking market share. It is understandable that internet service providers (ISPs), as gatekeepers of internet traffic, may be considered as being more than a conduit of contravening conduct but not a joint tortfeasor involved in a common design. In between those extremes lies the concept of authorisation in copyright which has a long history in Australia since the Copyright Act 1905 (Cth). The text of s 101(1A) of the Copyright Act, in particular s 101(1A)(a) and (c), derived from statements of Gibbs J in Moorhouse.

A Submission to the Advisory Council on Intellectual Property in Relation to the Issues Paper Relating to the Enforcement of Trade Marks - February 2002

With respect to “shape” marks, there would appear to be a “break”, imposed by the Australian Courts, in the logical conclusion that registration of a shape, which performs a functional purpose, or even further, is indistinguishable from the shape of the item or product, creates a perpetual monopoly in the manufacture of that product.

BIM-based lifecycle planning and specifications for sustainable cities of the future: A conceptual approach

Annually, several million tonnes of waste are produced from reworks, demolition, and use of substandard materials. Building Information Modelling (BIM), a digital representation of facilities and their constituent data, is a viable means of addressing some concerns about the impacts of these processes. BIM functionalities can be extended and combined with rich building information from specifications and product libraries, for efficient, streamlined design and construction. This paper conceptualises a framework for BIM-knowledge transfer from advanced economies for adaptation and use in urban development works in developing nations using the Sydney Down Under and Lagos Eko Atlantic projects as reference points. We present a scenario that highlights BIM-based lifecycle planning/specifications as agents of sustainable construction (in terms of cost and time) crucial to the quality of as-built data from early on in city development. We show how, through the use of BIM, city planners in developing nations can avoid high, retrospective (and sometimes wasteful) maintenance costs and leapfrog infrastructure management standards of advanced economies. Finally, this paper illustrates how BIM can address concerns about economic sustainability during city development in developing countries by enriching model objects with specification information sourced from a product library.

Development of a new regulatory model for occupational health and safety in the New South Wales coal industry: an issues paper for the New South Wales Department of Mineral Resources

This paper addresses the regulatory issues arising in developing a new regulatory model for the New South Wales Coal Industry. As such, it identifies the relevant literature on this subject, the options available for reform, and the experience of Australian and key international bodies responsible for the development of regulatory standards in this area. In particular it: Identifies the main shortcomings in the existing regulatory approach; Identifies the potential roles/main strengths and weaknesses of different types of standards (eg specification, performance, process and systems-based rules) and potential “best practice’ combinations of standards; Examines the appropriateness of the current regulatory regime whereby the general OHS legislation (including the general duty provisions) applies to mining in addition to the large body of regulation which is specific to mining; Identifies the importance of, and possible means of addressing, issues of worker participation within the coal mining industry; Draws on the literature on what motivates companies and individuals for the purpose of recommending key provisions for inclusion in new legislation to provide appropriate personal and organisational incentives; Draws on the literature on major hazards facilities to suggest the appropriate roles for OHS management systems and safety reports or comparable approaches (eg mine safety management plans); Draws on the United Kingdom (UK) and United States of America (USA) experience of coal mine safety and its regulation for comparative purposes, and for insights as to what sort of regulation most effectively reduces work related injury and disease in coal mining; Examines the relevant roles of International Labour Organisation (ILO) Conventions; Examines the extent to which different regulatory regimes would be appropriate to open cut and underground coal mining; and Examines options for reform. This paper is focussed specifically on the issues identified above.

Submission to the Australian Government’s Online Copyright Infringement Discussion Paper

Now is not the time to increase the strength of copyright law. Copyright law is facing a crisis of legitimacy: consumers increasingly appear to doubt its moral weight. To a large extent, this can be traced to the fact that Australian consumers do not believe they are being treated fairly by (predominantly US-based) copyright producers and distributors. Compared to their overseas peers, Australian consumers pay much more for access to books, films, television, and computer games, and are often subjected to long delays before material is available in Australia. Our research shows that this perceived unfairness increases the willingness of Australian consumers to seek out alternative distribution channels. Put simply, the failure of content distributors to meet consumer demand in Australia is a leading factor in copyright infringement. This submission argues that the best strategy to reduce copyright infringement in Australia, at the present time, is for distributors to focus on providing timely, affordable, convenient and fair access to copyright goods. Until this is done, the prevalence of copyright infringement in Australia should be seen as essentially a market problem, rather than a legal one. The Australian Government, meanwhile, should address the recommendations of the IT Pricing Report as a matter a priority. As a first step, the Government should urgently consider repealing the IP exception to competition law in s 51(3), as recommended by the Ergas committee, the IT Pricing report, and the ALRC. This change alone may go a long way to enhancing the efficiency of the copyright market in Australia.

Creative Commons Australia and Organization for Transformative Works submission to the Australian Government’s online copyright infringement discussion paper

This submission focuses on the adverse effects that the Government’s proposals are likely to have on the legitimate use of copyright works. Copyright exists to support the production of new expression. Because new expression always builds on existing culture, any extension of copyright protection necessarily also increases the costs of creative expression. As a threshold matter, we do not believe that these further increases to the force of copyright law are justified. In recent years, the balance at the heart of copyright law has tipped too far in the direction of established producers and distributors, and now imposes unnecessary costs on ordinary creators. The available evidence does not support a further increase in the penalties and enforcement mechanisms available under copyright law.
