Engineering graduates of today, face a working environment that assumes global mobility in the labour market. This challenge means, amongst universities worldwide, a demand to increase the globalisation of educational programs, context, and increase and support the mobility of students through mechanisms such as student exchange and double masters degrees. Engineering student mobility from Australia is low with only a few Engineering Faculties encouraging students to go internationally. This comparative study, using universities in Australia and Europe, of feedback from students who have been on exchange or proposing to go on exchange, employers and faculty addresses the motivators and barriers to student mobility and exchange from the perspectives of the university, faculty, students and employers. Recommendations will be presented on how student mobility and exchange can be improved, and mechanisms such as double Masters Degrees, dual accreditation and Erasmus Mundus 2009 – 2013 can be utilised to improve student mobility.

In this paper, we have compiled and reviewed the most recent literature, published from January2010 to December 2012, relating to the human exposure, environmental distribution, behaviour, fate and concentration time trends of polybrominated diphenyl ether (PBDE) and hexabromocyclododecane (HBCD) flame retardants, in order to establish their current trends and priorities for future study. Due to the large volume of literature included, we have provided full detail of the reviewed studies as Electronic Supplementary Information and here summarise the most relevant findings. Decreasing time trends for penta-mix PBDE congeners were seen for soils in northern Europe, sewage sludge in Sweden and the USA, carp from a US river, trout from three of the Great Lakes and in Arctic and UK marine mammals and many birds, but increasing time trends continue in Arctic polar bears and some birds at high trophic levels in northern Europe. This is a result of the time delay inherent in long-range atmospheric transport processes. In general, concentrations of BDE209 (the major component of the deca-mix PBDE product) are continuing to increase. Of major concern is the possible/likely debromination of the large reservoir of BDE209 in soils and sediments worldwide, to yield lower brominated congeners which are both more mobile and more toxic, and we have compiled the most recent evidence for the occurrence of this degradation process. Numerous studies reported here reinforce the importance o f this future concern. Time trends for HBCDs are mixed, with both increases and decreases evident in different matrices and locations and, notably, with increasing occurrence in birds of prey.

The globalisation and unintended impacts of chemicals sets substantial challenges for sustainable development and the protection of natural resources such as land and water. Currently, there are three key chemical Conventions, the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal which came into force in 1992, the 1993 Rotterdam Convention on Trade in Dangerous Chemicals and the Stockholm Convention on Persistent Organic Pollutants (POPs) (2004). These Conventions have as common features a mechanism for assessment of chemical safety, a process for the addition of new chemicals to a list of controlled substances and capacity building in developed countries. However, they only cover a small fraction of the chemicals manufactured and traded across the world. Defining effective regulation of chemicals is an on-going debate that has the potential to have a significant impact on vested commercial and political interests. A sustainable chemical industry should take account of evidence-based standards and through legal mechanisms adopt long-term precautionary evaluations rather than short-term market driven decisions. It is argued in this paper that effective international chemical regulation in the future will come from the adoption of sound chemical management and corporate social responsibility, but it recognised that this will face the challenge of economic disparity between countries and the potential export of regulatory risk from big chemical conglomerates to poorly regulated jurisdictions.

Investing in global environmental and adaptation benefits in the context of agriculture and food security initiatives can play an important role in promoting sustainable intensification. This is a priority for the Global Environment Facility (GEF), created in 1992 with a mandate to serve as financial mechanism of several multilateral environmental agreements. To demonstrate the nature and extent of GEF financing, we conducted an assessment of the entire portfolio over a period of two decades (1991–2011) to identify projects with direct links to agriculture and food security. A cohort of 192 projects and programs were identified and used as a basis for analyzing trends in GEF financing. The projects and programs together accounted for a total GEF financing of US$1,086.8 million, and attracted an additional US$6,343.5 million from other sources. The value-added of GEF financing for ecosystem services and resilience in production systems was demonstrated through a diversity of interventions in the projects and programs that utilized US$810.6 million of the total financing. The interventions fall into the following four main categories in accordance with priorities of the GEF: sustainable land management (US$179.3 million), management of agrobiodiversity (US$113.4 million), sustainable fisheries and water resource management (US$379.8 million), and climate change adaptation (US$138.1 million). By aligning GEF priorities with global aspirations for sustainable intensification of production systems, the study shows that it is possible to help developing countries tackle food insecurity while generating global environmental benefits for a healthy and resilient planet.

This article describes the development and evaluation of the U.K.’s new High-Resolution Global Environmental Model (HiGEM), which is based on the latest climate configuration of the Met Office Unified Model, known as the Hadley Centre Global Environmental Model, version 1 (HadGEM1). In HiGEM, the horizontal resolution has been increased to 0.83° latitude × 1.25° longitude for the atmosphere, and 1/3° × 1/3° globally for the ocean. Multidecadal integrations of HiGEM, and the lower-resolution HadGEM, are used to explore the impact of resolution on the fidelity of climate simulations. Generally, SST errors are reduced in HiGEM. Cold SST errors associated with the path of the North Atlantic drift improve, and warm SST errors are reduced in upwelling stratocumulus regions where the simulation of low-level cloud is better at higher resolution. The ocean model in HiGEM allows ocean eddies to be partially resolved, which dramatically improves the representation of sea surface height variability. In the Southern Ocean, most of the heat transports in HiGEM is achieved by resolved eddy motions, which replaces the parameterized eddy heat transport in the lower-resolution model. HiGEM is also able to more realistically simulate small-scale features in the wind stress curl around islands and oceanic SST fronts, which may have implications for oceanic upwelling and ocean biology. Higher resolution in both the atmosphere and the ocean allows coupling to occur on small spatial scales. In particular, the small-scale interaction recently seen in satellite imagery between the atmosphere and tropical instability waves in the tropical Pacific Ocean is realistically captured in HiGEM. Tropical instability waves play a role in improving the simulation of the mean state of the tropical Pacific, which has important implications for climate variability. In particular, all aspects of the simulation of ENSO (spatial patterns, the time scales at which ENSO occurs, and global teleconnections) are much improved in HiGEM.

The Deakin University (Melbourne, Australia) operational policy on 'International and Culturally Inclusive Curricula' states that Deakin will incorporate international/intercultural perspectives and inclusive pedagogies into its courses in order to prepare all students to perform capably, ethically and sensitively in international, multicultural, professional and social contexts.

This paper is about a specific project to internationalise the teacher education curriculum through the use of Information and Communication Technologies (ICT). This project is scoped in the context of the UNESCO thrust of 'Education for All' in agreeing that inclusive societies begin with inclusive education practices. In our view current strategies have been insufficient to ensure that marginalized and excluded children receive access to their right to education.

The project aims to operationalise part of the UNESCO Dakar Framework for high quality learning environments by responding to ‘…the diverse needs and circumstances of learners and giving appropriate weight to the abilities, skills and knowledge they bring to the teaching and learning process’ by minimising language acquisition barriers that can otherwise impede effective communication and learning.

In addition, we need to be mindful of the marginalisation of people from non-English speaking backgrounds and therefore, in this initiative we use ICT to bridge the 'tyranny of distance' and offer a curriculum that values cultural and linguistic diversity.

In this paper we will discuss how we intend to develop these project principles. In particular we will indicate our plans to use relatively low cost, accessible software to develop a virtual environment where students can enter text in their native language, view foreign language text in their native language, hear text in their own language and automatically encode text into MP3 files and attach the files to messages.

This paper addresses the issue of a current business phenomenon – ‘push back’. This phenomenon has been experienced by a number of transnational companies. It is embedded in the challenges of cross-cultural communication and involves the linkage of local culture activists with globalisation acitivists in an alliance to stop business growth. This exploratory investigation examines three multinational organisations using qualitative research. From the findings a model has been developed in an attempt to provide practitioners with a framework with which to understand ‘push back’. The complexity of combating alliances of this nature raises challenges for the current approaches to marketing and the need for a multi-stakeholder approach in cross-cultural communication is suggested.
