title: Oil dispersal modelling: reanalysis of the Rena oil spill using open-source modelling tools

authors: Jones, Hannah Frances Emily

subjects: Bay of Plenty

abstract: Oil spill forecast modelling is typically used immediately after a spill to predict oil dispersal and promote mobilisation of more effective response operations. The aim of this work was to map oil dispersal after the grounding of the MV Rena on Astrolabe Reef and to verify the results against observations. Model predictions were broadly consistent with observed distribution of oil contamination. However, some hot spots of oil accumulation, likely due to surf-zone and rip current circulation, were not well represented. Additionally, the model was run with 81 differing wind conditions to show that the events occurring during the grounding represented the typical likely behaviour of an oil spill on Astrolabe Reef. Oil dispersal was highly dependent on prevailing wind patterns; more accurate prediction would require better observations of local wind patterns. However, comparison of predictions with observations indicated that the GNOME model was an effective low-cost approach.

title: The weakest link: Revealing and modeling the architectural patterns of microservice applications

authors: Podolskiy, Vladimir

abstract: Cloud microservice applications comprise interconnected services packed into containers. Such applications generate complex communication patterns among their microservices. Studying such patterns can support assuring various quality attributes, such as autoscaling for satisfying performance, availability and scalability, or targeted penetration testing for satisfying security and correctness. We study the structure of containerized microservice applications via providing the methodology and the results of a structural graphbased analysis of 103 Docker Compose deployment files from opensourced Github repositories. Our findings indicate the dominance of a power-law distribution of microservice interconnections. Further analysis highlights the suitability of the Barabási-Albert model for generating large random graphs that model the architecture of real microservice applications. The exhibited structures and their usage for engineering microservice applications are discussed.

title: Overcoming ‘Being’ in Favour of Knowledge: The fixing effect of ‘mātauranga’

authors: Mika, Carl Te Hira

subjects: knowledge

abstract: It is common to hear Māori discuss primordial states of Being, yet in colonisation those very central beliefs are forced into weaker utterances. In this process those utterances merely conform to a colonised agenda. ‘Mātauranga’, a tidy term that overwhelmingly refers to an epistemological knowing of the world, colludes nicely with its English equivalent, ‘knowledge’, to further colonise those core contemplations of Being. Its plausibility relies on an orderly regard of things in the world. In education, historical and current practices of schooling pave the way for things in the world so that they amount to mātauranga for Māori, and even the term ‘ako’ will conspire in its own way. Both Novalis and Heidegger have the ability to identify subtly colonising philosophies, and may even propose some theoretical solutions for Māori.
