A comparative review of quantitative VFM methodology for PPP infrastructure project in Indonesia and Australia

The Government of Indonesia (GoI) increasingly relies on the private sector financing to build and operate infrastructures through public private partnership (PPP) schemes. However, PPP does not automatically provide the solution for the financing scheme due to value for money (VFM) issues. The procurement authority must show whether a PPP proposal is the optimal solution that provides best VFM outcome. The paper presents a literature review of comparing quantitative VFM methodology for PPP infrastructure project procurement in Indonesia and Australia. Public Sector Comparator (PSC) is used to assess the potential project VFM quantitatively in Australia. In Indonesia, the PSC has not been applied, where the PPP procurement authority tends to utilize a common project evaluation method that ignores the issues of risk. Unlike the conventional price bid evaluation, the PSC enables a financial comparison including costs/gains and risks. Since the construction of PSC is primarily on risk management approach, it can facilitate risk negotiation processes between the involved parties. The study indicates that the quantitative VFM methodology of PSC is potentially applicable in Indonesia for water supply sector. Various supporting regulations are available that emphasize the importance of VFM and risk management in infrastructure investment. However, the study also reveals a number of challenges that need to be anticipated, such as the need of a more comprehensive PPP policy at both central and local government level, a more specific legal instrument for bidding evaluation method and the issue of institutional capacity development in PPP Units at the local level.

Female genital mutilation : Australian law, policy and practical challenges for doctors

As long ago as 1994, the Family Law Council accepted it was likely that female genital mutilation (FGM) was being conducted in Australia. In 2010, doctors and hospitals reported that it is being conducted and that they are seeing female patients who have experienced FGM. It is impossible to obtain precise data about the extent to which it is performed in Australia, but data indicates that FGM is a relevant issue for Australian medical practitioners. The medical profession has an interest in this topic because its members may be asked to conduct FGM, advise those considering it, or treat female patients with effects from the practice. This article provides a background on the practice of FGM, explains the relevant Australian law, considers whether the current legal prohibition on FGM is justified, and discusses the practical challenges facing individual practitioners and the profession. To inform further discussions about methods of responding to demand for FGM, reference is made to strategies being promoted in African nations to abolish this cultural practice.

Towards practical implementation of time optimal trajectories for underwater vehicles

In this paper, we are concerned with the practical implementation of time optimal numerical techniques on underwater vehicles. We briefly introduce the model of underwater vehicle we consider and present the parameters for the test bed ODIN (Omni-Directional Intelligent Navigator). Then we explain the numerical method used to obtain time optimal trajectories with a structure suitable for the implementation. We follow this with a discussion on the modifications to be made considering the characteristics of ODIN. Finally, we illustrate our computations with some experimental results.

Optimal fluid injection strategies for in situ mineral leaching in two-dimensions

This paper examines the ground-water flow problem associated with the injection and recovery of certain corrosive fluids into mineral bearing rock. The aim is to dissolve the minerals in situ, and then recover them in solution. In general, it is not possible to recover all the injected fluid, which is of concern economically and environmentally. However, a new strategy is proposed here, that allows all the leaching fluid to be recovered. A mathematical model of the situation is solved approximately using an asymptotic solution, and exactly using a boundary integral approach. Solutions are shown for two-dimensional flow, which is of some practical interest as it is achievable in old mine tunnels, for example.

The politics of media policy [Review]

"The Politics of Media Policy opens with a highly insightful analysis of how to do media policy studies in original and significant ways. Unfortunately, by anchoring its empirical analysis closely to a desire to expose the hidden machinations of neo-liberal ideology, it loses focus the more that it moves out of the dominant terrain of political economy in the study of media ownership. Des Freedman has pointed to important new directions in media policy studies, but has unfortunately only got half way to developing a new synthesis for understanding the relationship between policy institutions and broader ideas." -- from author's personal website

Elements of an environmental offsets policy : a working paper towards a policy for an environmental banking scheme appropriate for Queensland

In the past eight years, Australia has adopted the use of environmental offsets as a means to compensate for environmental degradation from development. Queensland has more environmental offsetting policies than any other Australian State or Territory. The methodology has profound effects on development companies, landowners (both private and public), regional land planning, organizations, government agencies, monetary banking institutions and environmental conservation bodies.

Optimal voltage support mechanism in distribution networks

Optimal scheduling of voltage regulators (VRs), fixed and switched capacitors and voltage on customer side of transformer (VCT) along with the optimal allocaton of VRs and capacitors are performed using a hybrid optimisation method based on discrete particle swarm optimisation and genetic algorithm. Direct optimisation of the tap position is not appropriate since in general the high voltage (HV) side voltage is not known. Therefore, the tap setting can be determined give the optimal VCT once the HV side voltage is known. The objective function is composed of the distribution line loss cost, the peak power loss cost and capacitors' and VRs' capital, operation and maintenance costs. The constraints are limits on bus voltage and feeder current along with VR taps. The bus voltage should be maintained within the standard level and the feeder current should not exceed the feeder-rated current. The taps are to adjust the output voltage of VRs between 90 and 110% of their input voltages. For validation of the proposed method, the 18-bus IEEE system is used. The results are compared with prior publications to illustrate the benefit of the employed technique. The results also show that the lowest cost planning for voltage profile will be achieved if a combination of capacitors, VRs and VCTs is considered.

Parents’ risky choices around the IB Diploma

In recent years there has been a rapid growth in the International Baccalaureate Diploma(IBD), a secondary curriculum administered by the International Baccalaureate Organisation(IBO), as an alternative to the local curriculum in Australian schools in some schools. This growth is indicative of an increasing demand from Australian families for new educational structures, practices and processes. With more curriculum options and pathways such as the IBD available in the secondary education system, parents are faced with a more complex high stakes decision when it comes to choosing the optimal education path for their offspring, one which requires a careful assessment of potential outcomes and risks. This paper reports on the responses of 184 parents to an online survey conducted in 26 Australian schools that offer the IBD as a curricular alternative. It examines which parents either chose, or chose not to, enrol their children in the program, why, and what risks they perceived to be associated with that choice. The paper will compare the choice behaviour of the two groups of parents from a sociological perspective, framing the enquiry with reference to globalisation and neo-liberal education policy and its effect on parental choice of schooling. This paper will make evident how parental choice of educational alternatives has become a more complicated process for Australian families.

Vulnerability, insurance and policy: The learner driver's standard of care

In Cook v Cook the Australian High Court held that the standard of reasonable care owed by a learner driver to an instructor, conscious of the driver’s lack of experience, was lower than that owed to other passengers and road users. Recently, in Imbree v McNeilly, the High Court declined to follow this principle, concluding that the driver’s status or relationship with the claimant should no longer influence or alter the standard of care owed. The decision therefore provides an opportunity to re-examine the rationale and policy behind current jurisprudence governing the standard of care owed by learner drivers. In doing so, this article considers the principles relevant to determining the standard and Imbree’s implications for other areas of tort law and claimant v defendant relationships. It argues that Imbree was influenced by changing judicial perceptions concerning the vulnerability of driving instructors and the relevance of insurance to tortious liability.

Generalising across borders : policy and the limits of educational science.

AERA Distinguished Lecture, Annual Meetings of the American Educational Research Association, New Orleans, 8 April 2011. How well does educational policy, innovation and science cross borders? What are the parameters of a generalisable cultural science of education? What constitutes a principled policy 'borrowing'?

Educational policy for citizenship in the early years in Australia

This paper explores how young children are constructed in educational policy for citizenship in Australia, investigating tensions between early childhood educational discourses that construct young children as active citizens and the broader discourses of citizenship in Australian educational policy. There is a widespread discourse within early childhood education that regards young children as citizens and democratic participants in their own lives. This view is a reflection of the oft cited Article 12 in the UN Convention on the Rights of the Child (UNCRC 1989). However, educational policy and curriculum for citizenship in Australia, by and large, adheres to age and stage understandings of children, implicitly deeming young children unable to conceptualise abstract ideas of what it means to ‘be a good citizen’. This paper is located in the borders and intersections between discourses of early childhood education, young children as active participants in their own lives and what it means to be an active citizen in Australia. We are concerned with the interweaving of these ideas and how they are played out in educational policy making. This is an important perspective to take for governing and policy making are exercises in harnessing existing ideas and discourses, thereby rendering strategies and tactics for managing populations thinkable and sayable (Rose 1999). The ‘views from the margins’ (Burman 2008, p. 7) can provide alternative perspectives on policymaking, illuminating discursive tactics and strategies.

Policy filtering with XACML

This paper presents a modified approach to evaluate access control policy similarity and dissimilarity based on the proposal by Lin et al. (2007). Lin et al.'s policy similarity approach is intended as a filter stage which identifies similar XACML policies that can be analysed further using more computationally demanding techniques based on model checking or logical reasoning. This paper improves the approach of computing similarity of Lin et al. and also proposes a mechanism to calculate a dissimilarity score by identifying related policies that are likely to produce different access decisions. Departing from the original algorithm, the modifications take into account the policy obligation, rule or policy combining algorithm and the operators between attribute name and value. The algorithms are useful in activities involving parties from multiple security domains such as secured collaboration or secured task distribution. The algorithms allow various comparison options for evaluating policies while retaining control over the restriction level via a number of thresholds and weight factors.

Participation and e-democracy how to utilize web 2.0 for policy decision-making

This paper investigates in how to utilize ICT and Web 2.0 technologies and e-democracy software for policy decision-making. It introduces a cutting edge decision-making system that integrates the practice of e-petitions, e-consultation, e-rulemaking, e-voting, and proxy voting. The paper demonstrates how under precondition of direct democracy through the use this system the collective intelligence (CI) of a population would be gathered and used throughout the policy process.

Deliberation and collaboration in the policy process : a Web 2.0 approach

This paper is a summary of a PhD thesis proposal. It will explore how the Web 2.0 platform could be applied to enable and facilitate the large-scale participation, deliberation and collaboration of both governmental and non-governmental actors in an ICT supported policy process. The paper will introduce a new democratic theory and a Web 2.0 based e-democracy platform, and demonstrate how different actors would use the platform to develop and justify policy issues.
