Is there a difference between supervising international and domestic graduate students in Engineering and IT?

This paper explores a key issue identified in two studies of factors influencing the success of international and culturally and linguistically diverse (CALD) higher degree research graduate students. The studies include “A model for research supervision of international students in engineering and information technology disciplines” (MRS), which focused on identifying factors that influence successful supervision of culturally and linguistically diverse (CALD) and international higher degree research (HDR or graduate) students in Engineering and IT disciplines in three Australian universities, and “Culture, language and the whole graduate experience: Exploring best practices in international graduate supervision” (BPS), which focussed on exploring perceptions regarding best practices in graduate supervision by diverse stakeholders across Australia. Findings suggest most supervisors do not differentiate between international (or CALD) graduate students and non-CALD(domestic) students in terms of factors influence success in graduate studies.

The dynamics of global visual effects and games development industries: lessons for Australia’s creative industries development policy

The paper critiques the focus of creative industries policy on capability development of small and medium sized firms and the provision of regional incentives. It analyses factors affecting the competitiveness and sustainability of the games development industry and visual effects suppliers to feature films. Interviews with participants in these industries highlight the need for policy instruments to take into consideration the structure and organization of global markets and the power of lead multinational corporations. We show that although forms of economic governance in these industries may allow sustainable value capture, they are interrupted by bottlenecks in which ferocious competition among suppliers is confronted by comparatively little competition among the lead firms. We argue that current approaches to creative industries policy aimed at building self-sustaining creative industries are unlikely to be sufficient because of the globalized nature of the industries. Rather, we argue that a more profitable approach is likely to require supporting diversification of the industries as ‘feeders’ into other areas of the economy.

Market structure of international construction professional services: Evidences from top design firms

Construction professional service (CPS) in the international arena has been very competitive despite that the industry is proliferating at a high rate. To excel in international business, CPS firms have the importance of building overseas competition strategies on a proper understanding of the international CPS (I-CPS) market. However, subject to borderless trade, information technology–based networking, global outsourcing, and changing forms of procurement, the I-CPS market structure has become more covert, intricate, and unstraightforward than before. Through examining business competition among top international design firms, this study aims to identify the attributes of the I-CPS market structure from two perspectives—concentration and turnover. Data from Engineering News-Record over the period 2001–2011 were collected to calculate market concentration ratios and turnover indices. The results show that I-CPS competition is characterized by atomism, much turbulence with a steady increase in competition intensity, and the predominant role of new entrants and exiting firms in market turnovers. The combination of concentration and turnover is found useful to address the attributes of the I-CPS market structure, which favors I-CPS firms to formulate international competition strategies in due ways.

Verification and Operation of Adaptive Materials in Space

Piezoelectric polymers based on polyvinylidene fluoride (PVDF) are of interest as smart materials for novel space-based telescope applications. Dimensional adjustments of adaptive thin polymer films are achieved via controlled charge deposition. Predicting their long-term performance requires a detailed understanding of the piezoelectric property changes that develop during space environmental exposure. The overall materials performance is governed by a combination of chemical and physical degradation processes occurring in low Earth orbit as established by our past laboratory-based materials performance experiments (see report SAND 2005-6846). Molecular changes are primarily induced via radiative damage, and physical damage from temperature and atomic oxygen exposure is evident as depoling, loss of orientation and surface erosion. The current project extension has allowed us to design and fabricate small experimental units to be exposed to low Earth orbit environments as part of the Materials International Space Station Experiments program. The space exposure of these piezoelectric polymers will verify the observed trends and their degradation pathways, and provide feedback on using piezoelectric polymer films in space. This will be the first time that PVDF-based adaptive polymer films will be operated and exposed to combined atomic oxygen, solar UV and temperature variations in an actual space environment. The experiments are designed to be fully autonomous, involving cyclic application of excitation voltages, sensitive film position sensors and remote data logging. This mission will provide critically needed feedback on the long-term performance and degradation of such materials, and ultimately the feasibility of large adaptive and low weight optical systems utilizing these polymers in space.

A comparison of international and Australian rating tools for sustainability elements of residential property

The Australian housing sector contributes about a fifth of national greenhouse gas (GHG) emissions. GHG emissions contribute to climate change which leads to an increase in the occurrence or intensity of natural disasters and damage of houses. To ensure housing performance in the face of climate change, various rating tools for residential property have been introduced in different countries. The aim of this paper is to present a preliminary comparison between international and Australian rating tools in terms of purpose, use and sustainability elements for residential property. The methodologies used are to review, classify, compare and identify similarities and differences between rating tools. Two international tools, Building Research Establishment Environmental Assessment Methodology (BREEAM) (UK) and Leadership in Energy and Environmental Design for Homes (LEED-Homes) (USA), will be compared to two Australian tools, Green Star – Multi Unit Residential v1 and EnviroDevelopment. All four rating tools include management, energy, water and material aspects. The findings reveal thirteen elements that fall under three categories: spatial planning, occupants’ health and comfort, and environmental conditions. The variations in different tools may result from differences in local prevailing climate. Not all sustainability elements covered by international rating tools are included in the Australian rating tools. The voluntary nature of the tools implies they are not broadly applied in their respective market and that there is a policy implementation gap. A comprehensive rating tool could be developed in Australia to promote and lessen the confusion about sustainable housing, which in turn assist in improving the supply and demand of sustainable housing.

Bias-dependent effects in planar perovskite solar cells based on CH3NH3PbI3−xClx films

A unique bias-dependent phenomenon in CH3NH3PbI3−xClx based planar perovskite solar cells has been demonstrated, in which the photovoltaic parameters derived from the current–voltage (I–V) curves are highly dependent on the initial positive bias of the I–V measurement. In FTO/CH3NH3PbI3−xClx/Au devices, the open-circuit voltage and short-circuit current increased by ca. 337.5% and 281.9% respectively, by simply increasing the initial bias from 0.5 V to 2.5 V.

Carbon concentration dependent grain growth of Cu2ZnSnS4thin films

Organic solvents are commonly used in ink precursors of Cu2ZnSnS4 (CZTS) nanocrystals to make thin films for applications such as solar cells. However, the traces of carbon residual left behind by the organic solvents after high-temperature annealing is generally considered to restrict the growth of nanocrystals to form large grains. This work reported the first systematic study on the influence of carbon content of organic solvents on the grain growth of CZTS nanomaterial during high temperature sulfurization annealing. Solvents with carbon atom per molecule varying from 3 to 10 were used to made ink of CZTS nanocrystals for thin film deposition. It has been found that, after high temperature sulfurization annealing, a bilayer structure was formed in the CZTS film using organic solvent containing 3 carbon atoms per solvent molecule based on glycerol and 1,3-propanediol. The top layer consisted of closelypacked large grains and the bottom layer was made of as-synthesized nanoparticles. In contrast, the CZTS film made with the solvent molecule with more carbon atoms including 1,5-pentanediol (5 carbon atoms) and 1,7-heptanediol (7 carbon atoms) consisted of nanoparticles embedded with large crystals. It is believed that the carbon residues left behind by the organic solvents affected the necking of CZTS nanocrystals to form large grains through influencing the surface property of nanocrystals. Furthermore, it has also been observed that the solvent affected the thickness of MoS2 layer which was formed between CZTS and Mo substrate. A thinner MoS2 film (50 nm) was obtained with the slurry using carbon-rich terpineol as solvent whereas the thickest MoS2 (350 nm) was obtained with the film made from 1,3-propanediol based solvent. The evaluation of the photoactivity of the CZTS thin films has demonstrated that a higher photocurrent was generated with the film containing more large grains.

Global rules on conflict-of-laws matters in international insolvency law cases: An Australian perspective

The 2012 Report “Transnational Insolvency: Global Principles for Co-operation in International Insolvency Cases” – commissioned by The American Law Institute in conjunction with The International Insolvency Institute – annexed 23 “Global Rules on Conflict-of-Laws Matters in International Insolvency Cases”. These proposed “Global Rules” are intended to “serve as legislative recommendations” to (inter alia) promote uniformity and greater certainty in the unpredictable area of conflict of laws. This article provides a brief commentary upon the 23 proposed Global Rules from an Australian perspective (comparing the effect and intent of each rule with the current Australian conflict-of-laws position) and offers some conclusions as to the merits of the “Global Rules” initiative.

Access to essential medicines: Public health and international law

Historically, there have been intense conflicts over the ownership and exploitation of pharmaceutical drugs and diagnostic tests dealing with infectious diseases. Throughout the 1980’s, there was much scientific, legal, and ethical debate about which scientific group should be credited with the discovery of the human immunodeficiency virus, and the invention of the blood test devised to detect antibodies to the virus. In May 1983, Luc Montagnier, Françoise Barré-Sinoussi, and other French scientists from the Pasteur Institute in Paris, published a paper in Science, detailing the discovery of a virus called lymphadenopathy (LAV). A scientific rival, Robert Gallo of the National Cancer Institute, identified the AIDS virus and published his findings in the May 1984 issue of Science. In May 1985, the United States Patent and Trademark Office awarded the American patent for the AIDS blood test to Gallo and the Department of Health and Human Services. In December 1985, the Institut Pasteur sued the Department of Health and Human Services, contending that the French were the first to identify the AIDS virus and to invent the antibody test, and that the American test was dependent upon the French research. In March 1987, an agreement was brokered by President Ronald Reagan and French Prime Minister Jacques Chirac, which resulted in the Department of Health and Human Services and the Institut Pasteur sharing the patent rights to the blood test for AIDS. In 1992, the Federal Office of Research Integrity found that Gallo had committed scientific misconduct, by falsely reporting facts in his 1984 scientific paper. A subsequent investigation by the National Institutes of Health, the United States Congress, and the US attorney-general cleared Gallo of any wrongdoing. In 1994, the United States government and French government renegotiated their agreement regarding the AIDS blood test patent, in order to make the distribution of royalties more equitable... The dispute between Luc Montagnier and Robert Gallo was not an isolated case of scientific rivalry and patent races. It foreshadowed further patent conflicts over research in respect of HIV/AIDS. Michael Kirby, former Justice of the High Court of Australia diagnosed a clash between two distinct schools of philosophy - ‘scientists of the old school... working by serendipity with free sharing of knowledge and research’, and ‘those of the new school who saw the hope of progress as lying in huge investments in scientific experimentation.’ Indeed, the patent race between Robert Gallo and Luc Montagnier has been a precursor to broader trade disputes over access to essential medicines in the 1990s and 2000s. The dispute between Robert Gallo and Luc Montagnier captures in microcosm a number of themes of this book: the fierce competition for intellectual property rights; the clash between sovereign states over access to medicines; the pressing need to defend human rights, particularly the right to health; and the need for new incentives for research and development to combat infectious diseases as both an international and domestic issue.

International copyright law: A book review

n his 1994 book, Copyright's Highway, Paul Goldstein made the telling prophecy: The celestial jukebox may also portend more revolutional changes in international copyright markets. As the celestial jukebox disseminates information and entertainment over the air and without regard for national boundaries, the importance of the nation-state as a traditional guarantor of copyright may be replaced by international institutions such as the newly established World Trade Organization. In retrospect, it was an accurate prediction. The celestial jukebox has shown little respect for national boundaries. In particular, ephemeral file-sharing programs such as Napster, Freenet and Filetopia have posed difficulties for copyright law. International treaties have taken on larger significance and international institutions such as the World Intellectual Property Organization and World Trade Organization have assumed a greater role in regulating international copyright markets.

The impact of international potentials, entrepreneurial motivations and firm stages on new venture internationalisation

Past research on early internationalising firms often examined factors and motivations potentially influencing internationalisation activities separately. The purpose of this paper was to investigate a set of indicators and their interplay with each other. Firstly, the impact of (a) international potential in the form of the depth and diversity of international experience and network contacts was investigated. Secondly, it was examined to what extent (b) motivational factors and (c) firm stages affect the relationship between international potential and internationalisation activities. This paper used longitudinal data from the Comprehensive Australian Study of Entrepreneurial Emergence (CAUSEE). Results suggest that the international potential of a new venture as a whole is a significant determinant of subsequent internationalisation activities. However, having a diverse international experience from a variety of foreign countries appears to be more beneficial than a long-lasting experience from only a limited number of foreign countries. Furthermore, analyses showed that the interplay of high growth ambitions and the depth of international experience positively affect internationalisation activities. Opportunity or necessity driven entrepreneurship, however, neither exaggerate nor weaken the positive relationship between international potentials and internationalisation activities. Similarly, no moderation by firm stages was found.

Pt/WO3 nanoplatelet/SiC Schottky diode based hydrogen gas sensor

This paper presents the fabrication and study of a Schottky diode based on Pt/WO3 nanoplatelet/SiC for H2 gas sensing applications. The nanostructured WO3 films were synthesized from tungsten (sputtered on SiC) via an acidetching method using a 1.5 M HNO3 solution. Scanning electron microscopy of the developed films revealed platelet crystals with thicknesses in the order of 20-60 nm and lengths between 100-700 nm. The current-voltage characteristic and dynamic response of the diodes were measured in the presence of air and 1% H2 gas balanced in air from 25 to 300°C. Upon exposure to 1% H2, voltage shifts of 0.64, 0.93 and 1.14 V were recorded at temperatures of 120, 200 and 300°C, respectively at a constant forward bias current of 500 μA.
