Our research not only addresses the strategic purposes of expatriate assignments within multinational corporations but, unlike most earlier studies, extends the investigation to include their path-dependent outcomes. Adopting a knowledge transfer perspective we first re-define the principal assignment purpose categories of Edström and Galbraith (1977a) as business applications, organization applications and expatriate learning. These purpose categories are then conceptually related in terms of a four-part typological matrix based on individual-level knowledge-flow direction and role focus. Following a review of prior assignment purpose studies we posit that strategic expatriate assignment purposes should be considered not in isolation but relative to their potential outcomes. Adopting a single-case research design with multi-method data collection, we demonstrate the emergent nature of strategic assignment outcomes. It is shown for our transnational case organization that knowledge acquisition or learning by expatriates is an underestimated strategic assignment outcome, more so than either business or organization-related knowledge applications.

We investigate how expatriates contribute to the transnational firm's strategic objectives of global efficiency, national (”local”) responsiveness, and worldwide learning. We focus on expatriate knowledge application and experiential learning achievements, two assignment‐based outcomes of potential strategic value to the firm. We assess how the individual's everyday knowledge access and communication activities, measured by frequency and geographic extent, affect these assignment outcomes. Within our case organization, a prototype transnational firm, we find that expatriate knowledge applications result from frequent knowledge access and communication with the corporate headquarters and other global units of the firm. In contrast, their experiential learning derives from frequent access to hostcountry (local) knowledge that subsequently is adapted to the global corporate context. From a practical perspective, we conclude that experiential learning is an invaluable resource for both present and future corporate assignments. © 2007 Wiley Periodicals, Inc.

The Gippsland Basin of southeastern Australia is a post-orogenic, continental margin type of basin of Upper Cretaceous-Cainozoic age.Gippsland Basin evolution can be traced back to the establishment of the Strzelecki Basin, or ancestral Gippsland Basin, during the Jurassic. Gippsland Basin sedimentation commenced in the middle to late Cretaceous and is represented as a gross transgressive-regressive cycle consisting of the continental Latrobe Valley Group (Upper Cretaceous to Eocene or Miocene), the marine Seaspray Group (Oligocene to Pliocene or Recent), and finally the continental Sale Group (Pliocene to Recent).The hydrocarbons of the Gippsland Shelf petroleum province were generated within the Latrobe Valley Group and are trapped in porous fluvio-deltaic sandstones of the Latrobe. At Lakes Entrance, however, oil and gas are present in a marginal sandy facies of the Lakes Entrance Formation (Seaspray Group).The buried Strzelecki Basin has played a fundamental role in the development and distribution of the Cainozoic fold belt in the northern Gippsland Basin. The Gippsland Shelf hydrocarbon accumulations fall within this belt and are primarily structural traps. The apparent lack of structural accumulations onshore in Gippsland is largely due to a Plio-Pleistocene episode of cratonic uplift that was accompanied by basinward tilting of structures and meteoric water influx.The non-commercial Lakes Entrance field, located on the stable northern flank of the basin, is a stratigraphic trap and may serve as a guide for future exploration.

Domestic and foreign equity shocks on the Australian economy are analysed within a five‐variate structural vector autoregressive model, with identification achieved through long‐run restrictions based on the natural rate hypothesis, monetary neutrality, long‐run portfolio balance and purchasing power parity. The results show that real equity values were undervalued by 19 per cent by June 2005, with the gap narrowing thereafter. Foreign crises are important factors explaining this deterioration. The real wealth effects of equity market shocks impact significantly upon financial and goods market prices, whereas output tends to be immune. The model is also able to address puzzles that exist in the vector autoregression literature.

BackgroundChlamydia is a sexually transmitted infection that can cause serious upper genital tract infections, however, in Australia there are limited population data for chlamydia. Understanding the incidence of chlamydia will be important in the design of a chlamydia screening program in Australia.MethodWomen aged 16–25 years were recruited from sexual health clinics (SHC) and general practice clinics (GP) in South-Eastern Australia and consented to participate in longitudinal study over a 12-month period. Participants were requested to send back questionnaires and self-collected vaginal swabs through the post which were tested for chlamydia.ResultsOverall, 1116 women were recruited from 29 clinics; with a 79% retention rate.C trachomatisprevalence at baseline was 4.9% (95% CI: 2.9% to 7.0%) and incidence rate for the 12-month study period was 4.4 per 100 women-years (95% CI: 3.3% to 5.9%). PrevalentC trachomatiswas associated with having hadC trachomatispreviously [AOR: 2.0 (95% CI: 1.1% to 3.9%)], increased numbers of sexual partners [AOR: 6.4 (95% CI: 3.6% to 11.3%)] and unprotected sex [AOR: 3.1 (95% CI: 1.0% to 9.5%)]. Antibiotic use and older age were protective against having a prevalent infection ([AOR: 0.4 (95% CI: 0.2% to 1.0%)] and [AOR: 0.9 (95% CI: 0.8% to 1.0%)] respectively) and an incident infection ([AHR: 0.1 (95% CI: 0.0% to 0.6%)] and [AHR: 0.4 (95% CI: 0.2% to 0.8%)] respectively). IncidentC trachomatiswas also associated with more partners [AHR: 4.0 (95% CI: 1.9% to 8.6%)]. More than 20% of women withC trachomatishad a re-infection during the study [20.3% (95% CI: 11.6% to 31.7%)] with an infection rate of 20.0 (95% CI: 11.9% to 33.8%) per 100 women years. The median chlamydia organism load was 1.4×105/5цl and the most common serovar identified was serovar E (51.9%).ConclusionChlamydia is a common STI in young Australian women, and an incidence of 4.9 per 100 women years for chlamydia suggests annual testing is appropriate for a chlamydia screening program. The high re-infection rate indicates the importance of partner notification and re-testing 3 months after treatment.
