Harnessing Artificial Intelligence and Data Linkage to Improve Outcomes for Justice-involved Young People


Summary: This project will look at how artificial intelligence can help solve problems in research on justice involvement and health, respectfully and ethically, with a focus on using “linked” data from databases of people who come into contact with the criminal justice system in Australia, the UK, and Brazil. We have already identified some possibilities of how AI can improve the body of evidence on health outcomes for young people charged or sentenced to community orders or youth detention. For example, there is so much information on family court data (and, sadly, coronial reports) on the circumstances that could have potentially avoided ill-health, self-harm, and even suicide for justice-involved people. We want to ensure AI is there to help and not to exacerbate further the disadvantages faced by some of the most vulnerable young people in our society.

Decolonising data science teaching and learning


Summary: Does the way data science is taught adequate and inclusive, or is everyone forced to follow the same approach? Do the datasets and case studies used for teaching and evaluation be representative of diverse contexts and historical perspectives, or do they represent a biased vision of such contexts? Do data science assessment activities effectively measure students' critical thinking and innovative skills, or do they simply assess their technical ability to memorize and repeat the same solutions? This education-focussed project concentrates on two aspects of data science in ligth of decolonising: teaching and assessment. We will investigate these and other questions, and produce some guidelines for incorporating decolonising concepts into teaching and assessment resources related to data science courses.

Evaluating effects of social inequalities on the COVID-19 pandemic in a low- and middle-income country


Summary: This project aims at to create a Social Disparities Index (SDI) to measure inequalities relevant to the COVID-19 pandemic, such as unequal access to healthcare and regions more vulnerable to infection. In Brazil, markers of inequality are associated with COVID-19 morbidity and mortality. IDS will capture these markers from COVID-19 surveillance data and build a public visualisation dashboard to share the index and patterns of COVID-19 incidence and mortality with the broader community. This will enable health managers and policymakers to monitor the pandemic situation in the most vulnerable populations and target social and health interventions.

Standardisation of wearable-based algorithms for healthcare applications in developing countries


Summary: This project aims at to develop a novel standardised framework to better inform algorithms for a more harmonised gait assessment in Parkinson's disease (PD), particularly for developing countries where guidance is lacking. This project will lead to the design of an online simulation tool to test algorithms.

This will better guide PD assessment for sustainable health, promoting and encouraging low-cost wearables as routine diagnostics in developing countries. This framework will also be adapted to the needs of those in developed regions.

Analysis of performance models applied to high-performance hybrid architectures


Summary: This project aims at to study performance models used for high performance processing in hybrid architectures composed by multicore CPUs and manycore GPUs. We want to identify and measure some metrics related to performance and processing capacity/elasticity, as well as limitations related to application execution, tools for applications development and other aspects related to each architecture. A set of applications belonging to different classes (highly coupled, bag of tasks and data-intensive) will be evaluated in terms of their requirements (resources needed, data movement etc), aiming at to define a set of operating characteristics for each class. As major outcomes, the project must generate a detailed analysis on the suitability of current performance models applied to hybrid architectures and propose some extensions in order to efficiently support such architectures.
