Australia-Indonesia cooperation on asylum-seekers: a case of 'incentivised policy transfer'

Australia and Indonesia have engaged in cooperation on asylum policy since the late 1990s, bilaterally on immigration detention and people-smuggling agreements, and multilaterally through the Bali Process. Seen from a global perspective, this form of cooperation is one of many such bilateral and multilateral agreements that stymie the ability of asylum-seekers to gain effective and durable protection. This article argues that policy transfer theory can explain how these agreements are achieved, their political implications, and their outcome for the refugee regime and the asylum-seekers reliant on the regime for protection. In the case study of Australia and Indonesia, the authors argue that the cooperation is best understood as a form of ‘incentivised policy transfer’, whereby Australia has provided substantial financial and diplomatic incentives to Indonesia to adopt policies consistent with Australia's own. The implications for asylum-seekers in the Asia-Pacific region are substantial, and include an increase in the use of immigration detention in Indonesia and the introduction of border security measures that restrict the ability of asylum-seekers to reach territory where they may claim protection under the Convention Relating to the Status of Refugees.

Modeling of light propagation through biological tissues : a novel approach

An efficient numerical technique for modeling biological tissues using the radiative transfer equation is presented. Time dependence of the transient radiative transfer equation is approximated using Laguerre expansion. Azimuthal angle is discretized using the discrete ordinates method and the resulting set of ordinary differential equations is solved using the Runge-Kutta-Felhberg method.

Laguerre Runge-Kutta-Fehlberg method for simulating laser pulse propagation in biological tissue

An efficient algorithm for solving the transient radiative transfer equation for laser pulse propagation in biological tissue is presented. A Laguerre expansion is used to represent the time dependency of the incident short pulse. The Runge–Kutta– Fehlberg method is used to solve the intensity. The discrete ordinates method is used to discretize with respect to azimuthal and zenith angles. This method offers the advantages of representing the intensity with a high accuracy using only a few Laguerre polynomials, and straightforward extension to inhomogeneous media. Also, this formulation can be easily extended for solving the 2-D and 3-D transient radiative transfer equations.

Local total and radiative heat-transfer coefficients during the heat treatment of a workpiece in a fluidised bed

The heat-transfer coefficients around a workpiece immersed in an electrically heated heat treatment fluidised bed were studied. A suspension probe designed to simulate a workpiece of complex geometry was developed to measure local total and radiative heat-transfer coefficients at a high bed temperature. The probe consisted of an energy-storage region separated by insulation from the fluidised bed, except for the measuring surface, and a multi-thermocouple measurement system. Experiments in the fluidised bed were performed for a fluidising medium of 120-mesh alumina, a wide temperature range of 110–1050 °C and a fluidising number range of 1.18–4.24. It was found that the workpiece surface temperature has a more significant effect on heat transfer than the bed temperature. The total heat-transfer coefficient at the upper surface of the workpiece sharply decreased at the start of heating, and then steadily increased as heating progressed, while a sharp decrease became a rapid increase and then a slow increase for the radiative heat-transfer coefficient. A great difference in the heat-transfer coefficients around the workpiece was observed.

Chalk and cheese: Grounded theory case studies of the introduction and usage of activity-based information in two British banks

During the conduct of a research project into influences on the use of management accounting information, the use of activity-based techniques and information in two British banks was studied by the application of grounded theory principles. Juxtaposition of these two case studies reveals insights about the managers' significantly different experiences of ongoing applications, and the different outcomes of implementation that may arise, despite commonality in the organization and industry environment. This paper presents these two case studies, highlights the similarities and differences between them, and draws some conclusions about the causes of the differences. Factors that can be managed to achieve a greater use of these particular management accounting techniques, and the information they generate, are revealed. In particular, the findings suggest that the introduction of transfer charging between the bank's internal units highlights the need for activity-based techniques, and that education, communication and implementor support are vital, both for implementation success and for the widespread continuing use of the resultant applications. Further, between the two cases the greatest consensus was found in a common concern about the amount of detail in the databank and reports.

Numerical simulation of heat and mass transfer in fluidised bed heat treatment furnaces

In this paper, a novel combined theoretical and computational model is developed to simulate the heat and mass transfer between a fluidised bed and a workpiece surface, and within the workpiece by considering the fluidised bed as a medium consisting of a double-particle layer and an even porous layer. The heat and mass-transfer flux from the fluidised bed to the workpiece surface is contributed by dense and bubble phases, respectively. The convective heat and mass transfer is simulated by analysing the gas dynamics in the fluidised bed, while radiative heat transfer is modelled by simulating photon emission in a three-dimensional particle array. The simulation shows that convection is approximately constant, while radiation contributes significantly to the heat transfer. The heat-transfer coefficient on an immersed surface near particles is about 6–10 times that on other areas. The transient heat and mass-transfer coefficient, heat and mass-transfer flux on any surface of the workpiece, transient temperature and carbon distributions at any position of the workpiece during the metal carburising process are studied with the simulation.

Particle dynamics and heat transfer at workpiece surface in heat treatment fluidised beds

The particle behaviour is studied by the analysis of particle images taken with a high speed CCD digital video camera. The comparison of particle dynamics is performed for the fluidised beds without part, with single part and with multi-parts. The results show that there are significant differences in particle behaviours both in different beds and at different locations at part surfaces. The total and radiative heat transfer coefficients at different surfaces of a metallic component in a high temperature fluidised bed are measured by a heat transfer probe developed in the present work. The principle of the heat transfer probe is to measure the change in temperature of the heated metallic piece with time and, then, to extract the heat flux and heat transfer coefficients. The structure of the probe is optimized with numerical simulation of energy conservation for measuring the heat transfer coefficient of 150~600 W/m2 K. The relationship between the particle dynamics and the heat transfer is analysed to form the basis for future more rational designs of fluidised beds as well as for improved quality control.

Scaffolding students' learning in EME150 introduction to learners and learning theory : on looking back

This is a reflective article on the importance scaffolding in the EME 150 unit taught in collaboration with Deakin University Australia. Being the first unit introduced in the second semester of the first academic year, students were given a lot of support to enhance their understanding and learning since this curriculum was solely developed by Deakin University and introduced for the first time in teachers education curriculum. The scaffolding tools discussed in this article enabled students to a) establish deep learning of the theory. b) engage in collaborative and engaged learning which established good ethical relations between students c) transfer learning by applying theory into practice.

The Integrating Theory, Evidence and Action (ITEA) method: a procedure for helping practitioners translate theory and research into action

Introduction: The aim of this article is to describe and explain a new method for integrating theory and evidence that enables practitioners to translate evidence into action applied in their practice. Method: A new multiple methods procedure called the Integrating Theory, Evidence and Action method is described. It is a mixed method that progresses through seven distinct steps: clinical question, framework, identification, deconstruction, analysis, reconstruction, and transfer/utilization. An example of using this method to review evidence around occupational therapy with people recovering from alcohol misuse and/or abuse is provided. Findings: This method highlights the importance of theory, tests the empirical strength of theories, includes diverse forms of evidence, and encourages the integration of knowledge within clinical practice. Conclusion: The Integrating Theory, Evidence and Action method is accessible and useful to practitioners and will support their efforts to make their practice evidence based. Current methods of evidence-based practice focus mostly on research evidence (particularly quantitative evidence); however, research is only one of the ways of knowing that practitioners draw upon to guide their practice. This method enables occupational therapists to integrate theory, evidence, and practice in a coherent and translatable way.

Engineers' professional learning: a practice-theory perspective

With the increasing challenges facing professional engineers working in more complex, global and interdisciplinary contexts, different approaches to understanding how engineers practice and learn are necessary. This paper draws on recent research in the social sciences from the field of workplace learning, to suggest that a practice-theory perspective on engineers' professional learning is fruitful. It shifts the focus from the attributes of the individual learner (knowledge, skills and attitudes) to the attributes of the practice (interactions, materiality, opportunities and challenges). Learning is thus more than the technical acquisition and transfer of knowledge, but a complex bundle of activities, that is, social, material, embodied and emerging. The paper is illustrated with examples from a research study of the learning of experienced engineers in the construction industry to demonstrate common practices – site walks and design review meetings – in which learning takes place.

Analytical thermal study on nonlinear fundamental heat transfer cases using a novel computational technique

In this paper a novel computational technique called Parameterized Perturbation Method (PPM) is used to obtain the solutions of nonlinear fundamental heat conduction equations. Three well known problems in the area of heat transfer are addressed to be solved. An analytical investigation is carried out for: (a) the temperature distribution in a fin with a temperature-dependent thermal conductivity, (b) the cooling of the lumped system with variable specific heat, and (c) the temperature distribution of a convective-radiative fin. The validity of the results of PPM solution was verified via comparison with numerical results obtained using a fourth order Runge-Kutta method. These comparisons revealed that PPM is a powerful approach for solving these problems. Also, the results showed that the main attributions of this method are very straightforward calculations and low computational burden compared to previous analytical and numerical approaches.
