Although values are distal predictors of AOD use, the extent to which SSA Australian youth apply their values in AOD use could be a function of their psychological flourishing and Bicultural Identity Integration (BII). The aim of this study was to test a predictive model that combines values, psychological flourishing and BII to explore how the interaction of personal values and adaptive resources are related to …

Marching To The Beat: The Role Of Complementor Alignment In The Architectural Evolution Of Ecosystems, Pengxiang Zhang, Liang Chen, Yang Yang, Sali Li

Research Collection Lee Kong Chian School Of Business

The evolution of innovation ecosystems hinges on the effective coordination between ecosystem leaders and complementors. While ecosystem-sponsored architectural innovations create new technological opportunities for complementors, they may unintentionally disrupt the performance of complementor products that were originally developed based on legacy architectural designs. This study provides empirical evidence of these disruptive effects and explores how complementors’ alignment with the ecosystem leader mitigates such challenges. Focusing on Apple’s release of Core ML—a proprietary artificial intelligence module—in its mobile ecosystem, we employ a difference-in-differences design to investigate variations in complementor performance after adopting this ecosystem-sponsored architectural innovation. Our findings reveal that complementors’ …

Emergency Reinfusion Of Vaginally Salvaged Red Cells After Vacuum-Assisted Vaginal Delivery In A Jehovah's Witness: A Case Report, William Hughes

Peninsula Medical School

Perinatal blood management is critical for all obstetric patients as peripartum haemorrhage is common, unpredictable, and consequences can be severe. Patients who do not consent to allogeneic transfusion of blood products introduce additional complexity and are at greater risk of morbidity and mortality. There is growing evidence that reinfusion of autologous blood salvaged from vaginal deliveries is safe and can be lifesaving. Delivering this potentially lifesaving care requires that staff well trained in intraoperative cell salvage are always resident on the delivery suite, and that the delivery suite multidisciplinary team is familiar with the procedure. Here we present a case …
