International students have a substantial presence in western business schools. Yet, research on international students' experiences remains sparse. Following recent calls to understand the international student-educational institution relationship, we examine the content, formation, and fulfilment of their psychological contract. We conduct a qualitative study of international students in two Australian business schools with large international student cohorts. The findings indicate that international students use social and institutional sources to create the contract, which, when fulfilled, leads to positive educational and psychological outcomes. Our research contributes to the business and international education literature by identifying the key content of the contract. We also highlight the interconnected roles of three tiers of the institution -- academic staff, business school and university -- in fulfilling the contract. Knowledge of international students' psychological contract will help business schools better manage the student-institution relationship and create a sustainable international student expansion strategy.

Community engagement is increasingly important in environmental management. While such engagement has tended to comprise only one-way communication, genuine engagement often requires meaningful cross-cultural communication. This paper explores issues surrounding engagement with Australian indigenous communities, suggesting that the construction of the cultural identity of these communities is an important impediment to meaningful social engagement. Drawing on schema theory and the notion of Bhabha's interstitial space, we argue that environmental management needs to embrace such ideas. Using examples from a study of the non-indigenous construction of Australian Aboriginal identity through a long-established Australian newspaper, we explore implications of non-indigenous construction of Australian Aboriginal identity in environmental management. We argue, thus, that contemporary environmental management needs to encourage a focus on conscious engagement or self-critique of identity statements. This focus would have an emphasis on the constructedness of cultural identity and conscious rejection of the unthinking assumptions they engender.

Queensland fruit fly (Q-fly), Bactrocera tryoni (Froggatt), is a significant pest of horticultural crops in Australia. The sterile insect technique (SIT) is currently employed to eradicate outbreaks in fruit fly free regions and may also be used to suppress populations in endemic regions. For SIT to succeed, it is imperative that the released sterile males survive, disperse, attain sexual maturity, and are sexually competitive against their wild rivals. Q-fly SIT programmes have conventionally held adult flies for two to three days and have sometimes fed them only sugar before release, providing little time or nutrition for development prior to release. We investigated whether a 5-d pre-release holding period and provision of yeast hydrolysate (YH) together with sugar in the pre-release diet increase abundance of mature male Q-fly in the field. Indicating increased survivorship and/or maturation, the combination of YH feeding and 5-d pre-release holding period resulted in 6–8 times more recaptures of mature male flies in cuelure traps than was the case for flies released at 2 d with or without YH and for flies released at 5 d without YH. Flies held for 5 d and fed YH were relatively more abundant than flies from other treatments in traps close to the release point and were as abundant as other treatments in traps at the greatest assessed distances. These findings strongly support a recommendation that sterile Q-flies be provided a pre-release diet of YH and sugar and be held for 5-d post-eclosion before release. [ABSTRACT FROM AUTHOR]

Abstract: This study examines the psychometric properties of the Career Adapt-Abilities Scale (CAAS) and its relation to adaptivity (i.e., learning goal orientation, proactive personality, and career optimism) among Australian university students (N=555). Results demonstrated adequate levels of test–retest reliability (r=.61 to .76) and internal consistency (α=.83 to .94) for the CAAS full scale and subscales over a 4-week interval between measurements. Confirmatory factor analysis also supported the multidimensional and hierarchical model of career adaptability resources. The factor structure generally corresponded with that obtained from other CAAS international validation, thus, expanding its cross-national measurement equivalence. In addition, correlation results supported the predicted positive association between career adaptability and adaptivity in the form of learning goal orientation, proactive personality, and career optimism. Taken together, the present findings confirm the psychometric utility of CAAS in the Australian context and substantiate the proposition that higher personal adaptive readiness relates to better career adaptability among young people.

In 2010, the International Council for Science (ICSU) and the International Social Science Council (ISSC) published their Grand Challenges in Global Sustainability Research, seeking to mobilise researchers in a 10-year scientific effort to address what they call the “grand challenges in global sustainability”. In this paper, we ask whether these Grand Challenges are relevant to Australian environmental management. We examine this from two angles, insights from public perception surveys, and our own survey data. Public attitudes surveys indicate public ambiguity on the knowledge base, a finding that implies an immediate need for improved public communication of scientific knowledge. Our on-line survey, attached to a conference, Innovative Solutions for Environmental Challenges, targeted Australian environmental managers and scientists’ views on critical issues. The results mirrored global scientists’ views on the need to find ways for the scientific, social and political communities to work together to develop innovative approaches to solving future environmental concerns. Importantly, we found that the specific responses were context and scale dependent, while highlighting the inherent tensions between maintaining production and consumption, and protection of resources and ecosystem services.

Using a recent case study of community reaction to proposed coal-seam gas mining in eastern Australia, we illustrate the role of community views in issues of natural resource use. Drawing on interviews, observations and workshops, the paper explores the anti-coal-seam gas social movement from its stages of infancy through to being a national debate linking community groups across and beyond Australia. Primary community concerns of inadequate community consultation translate into fears regarding potential impacts on farmland and cumulative impacts on aquifers and future water supply, and questions regarding economic, social and environmental benefits. Many of the community activists had not previously been involved in such social action. A recurring message from affected communities is concern around perceived insufficient research and legislation for such rapid industrial expansion. A common citizen demand is the cessation of the industry until there is better understanding of underground water system interconnectivity and the methane extraction and processing life cycle. Improved scientific knowledge of the industry and its potential impacts will, in the popular view, enable better comparison of power generation efficiency with coal and renewable energy sources and better comprehension of the industry as a transition energy industry. It will also enable elected representatives and policy makers to make more informed decisions while developing appropriate legislation to ensure a sustainable future. [ABSTRACT FROM AUTHOR]

The radiation biology of two geographically isolated populations of the light brown apple moth [Epiphyas postvittana (Walker)] was studied in Australia and New Zealand as an initiation of a SIT/F1 sterility program. Pharate and ≤ 2 d pre-emergence pupae were exposed to increasing radiation doses up to a maximum dose of 300 Gy. Fertility and other life history parameters were measured in emerging adults (parental) and their progeny (F1-F3 adults). Parental fecundity was significantly ,affected by increasing irradiation dose in pharate pupae only. For both populations, parental egg fertility declined with increasing radiation. This was most pronounced for the irradiated parental females whose fertility declined at a higher rate than of irradiated males. At 250 Gy, females ≤ 2 d preemergence pupae produced few larvae and no adults at F No larvae hatched from 250 Gy-irradiated female pharate pupae. At 300 Gy, males still had residual fertility of 2-5.5%, with pharate pupae being the more radio-sensitive. Radiation-induced deleterious inherited effects in offspring from irradiated males were expressed as increased developmental time in F larvae, a reduction in percent F1 female survival, decreased adult emergence and increased cumulative mortality over subsequent generations. Males irradiated at ≥150 Gy produced few but highly sterile offspring at F1 and mortality was >99% by F2 egg. [ABSTRACT FROM AUTHOR]

A population model was derived for light brown apple moth, Epiphyas postvittana (Walker) (Lepidoptera: Tortricidae), subject to the sterile insect technique (SIT). The model was parameterized from the literature and from recent laboratory studies conducted in New Zealand and Australia. Relationships were fitted for several model parameters that vary with irradiation dose, allowing the model to simulate effectively complete sterility at 300 Gy through inherited sterility occurring from lower doses. At 300 Gy, the model suggests that eventual population extinction is 95% probable when the ratio of released to wild males in monitoring traps exceeds 6.4. Higher overflooding rates would be required to achieve eradication more rapidly. The optimal release interval, in terms of minimizing the required rate of production of factory moths, is approximately weekly. There is little advantage in releasing males only compared with releasing both sexes. Female-only releases are unlikely to be a useful tool for inherited sterility eradication because there is no reduction in the fertility of F1 offspring. The critical release rate required to halt population increase declines with decreasing irradiation dose, but at doses of <171 Gy there is a risk that irradiated-lineage moths may form a self-sustaining population, making eradication by SIT alone impossible. The model suggests that a dose of around 200 Gy may be optimal because the resulting inherited sterility would reduce by a third the number of factory moths required compared with 300 Gy.

The article offers information on a research paper related to workplaceboundaries in multinational organizations among Australian and Singaporean executives. It reports that the research aimed at exploring the intercultural differences in the nature of Australians and Singaporeans who works in multinational organizations. It discusses the cultural differences which influence the level of interaction and communication among executives working at organization. It reports that Singaporeans create more impermeable boundaries which restrict intercultural interactions in workplace than Australians.

The incorporation of sown pastures as short-term rotations into the cropping systems of northern Australia has been slow. The inherent chemical fertility and physical stability of the predominant vertisol soils across the region enabled farmers to grow crops for decades without nitrogen fertiliser, and precluded the evolution of a crop--pasture rotation culture. However, as less fertile and less physically stable soils were cropped for extended periods, farmers began to use contemporary farming and sown pasture technologies to rebuild and maintain their soils. This has typically involved sowing long-term grass and grass--legume pastures on the more marginal cropping soils of the region. In partnership with the catchment management authority, the Queensland Murray--Darling Committee (QMDC) and Landcare, a pasture extension process using the LeyGrain™ package was implemented in 2006 within two Grain & Graze projects in the Maranoa-Balonne and Border Rivers catchments in southern inland Queensland. The specific objectives were to increase the area sown to high quality pasture and to gain production and environmental benefits (particularly groundcover) through improving the skills of producers in pasture species selection, their understanding and management of risk during pasture establishment, and in managing pastures and the feed base better. The catalyst for increasing pasture sowings was a QMDC subsidy scheme for increasing groundcover on old cropping land. In recognising a need to enhance pasture knowledge and skills to implement this scheme, the QMDC and Landcare producer groups sought the involvement of, and set specific targets for, the LeyGrain workshop process. This is a highly interactive action learning process that built on the existing knowledge and skills of the producers. Thirty-four workshops were held with more than 200 producers in 26 existing groups and with private agronomists. An evaluation process assessed the impact of the workshops on the learning and skill development by participants, their commitment to practice change, and their future intent to sow pastures. The results across both project catchments were highly correlated. There was strong agreement by producers (>90%) that the workshops had improved knowledge and skills regarding the adaptation of pasture species to soils and climates, enabling a better selection at the paddock level. Additional strong impacts were in changing the attitudes of producers to all aspects of pasture establishment, and the relative species composition of mixtures. Producers made a strong commitment to practice change, particularly in managing pasture as a specialist crop at establishment to minimise risk, and in the better selection and management of improved pasture species (particularly legumes and the use of fertiliser). Producers have made a commitment to increase pasture sowings by 80% in the next 5 years, with fourteen producers in one group alone having committed to sow an additional 4893 ha of pasture in 2007-08 under the QMDC subsidy scheme. The success of the project was attributed to the partnership between QMDC and Landcare groups who set individual workshop targets with LeyGrain presenters, the interactive engagement processes within the workshops themselves, and the follow-up provided by the LeyGrain team for on-farm activities.

This paper presents a case study, based on the experiences of two senior Aboriginal traditional owners who were engaged in negotiations surrounding the establishment of a Regional Forest Agreement (RFA) in southeast Queensland. This case is notable as an illustration of the capacity of natural resource management planning, through negotiation within a formal process, to extinguish native title. Importantly, the personal experiences of two senior Aboriginal people provide an insight into a situation designed to enhance interactions between government and community, with the overt intention of improving natural resource management. However, the record of this personal experience indicates that the communication was less than satisfactory and that the outcomes, at least in terms of the experiences recorded here, of the individual senior Aboriginal community members, was less than satisfactory. We conclude that, despite best intentions, there is an important lack of provision for community influence or power, including any legal or administrative institutional framework. We also conclude that there are important institutional and social processes of engagement still to be developed, including ways of engaging the community more widely that has conventionally been the case.
