This study analyzed and explored the cognitive load of Australian energy market operators managing one of the longest inter-connected electrical networks in the world. Each operator uses a workstation with seven screens in an active control room environment, with a large coordination screen to show information and enable collaboration between different control centers. Cognitive load was assessed during both training scenarios and regular control room operations via the integration of subjective and physiological measures. Eye-tracking glasses were also used to analyze (...) the operators gaze behavior. Our results indicate that different events, different participants for the same session, and different periods of one session all have varying degrees of cognitive load. The system design was observed to be inefficient in some situations and to have an adverse affect on cognitive load. In critical situations for instance, operator collaboration was high and the coordination screen was used heavily when collaborating between two control centers, yet integration with the system could be improved. Eye tracking data analysis showed that the layout of applications across the seven screens was not optimal for many tasks. Improved layout strategies, potential combination of applications, redesigning of certain applications, and linked views are all recommended for further exploration in addition to improved integration of procedures and linking alarms to visual cues.

Taken at face value the introduction in 2021 of Australia’s News Media and Digital Platforms Mandatory Bargaining Code (“the Code”) may appear “world leading,” innovative, and, in general, a productive and strategic intervention to reverse the decline of public interest journalism. It is claimed that in the Australian news industry context, an annual transfer of around $200 million between two platform companies – Google and Meta – and news businesses has now been put in place (Sims, 2022). All major news (...) media companies in Australia, if not smaller more independent ones, have greatly benefitted from the new Code, and anecdotally it appears that the funding has resulted in the creation of significant numbers of new journalists being hired. Yet the exact investment destination and ultimate beneficiaries of the funding are not known beyond the corporate walls of the recipients. The article points to the transparency and sustainability problems inherent to the new Code, arguing that an alternative approach to funding public interest journalism might be a levy funded by the platforms.
