Ageing in autism is a neglected area of research, accounting for less than 1% of all indexed autism research pre-2022. Gavin will begin by discussing how historic changes to the diagnostic criteria of autism has resulted in upwards of 90% of autistic people over 50 being undiagnosed. He will then discuss how different but complementary conceptual approaches can be used to examine ageing in autism (i.e., dimensional trait-based approaches and categorical diagnosis-based approaches). Using these different but complimentary approaches, he will share a high-level overview of some recent empirical research findings from a range of studies related to cognition, health, wellbeing, and life experiences. These studies will be pieced together to create a broad picture of where support can be provided to improve the quality of life and outcomes of ageing autistic people, to ensure they live long and happy lives.

Many people think of the New Testament as a set of Christian texts that provide information about the authors’ views on being Christian. There are problems with talking about “Christians” in connection with the New Testament, however. This talk will explore some of those problems, drawing on my research on the letters of the apostle Paul. It will discuss how reading through the lens of “Christians” can obscure the situation of women and enslaved persons in the ancient world. It will also explore how it may contribute to the phenomenon of accidental anti-Judaism among readers of the Bible today.

Autistic adults have a three to five-fold elevated risk of premature death by suicide compared to the general population; in the United Kingdom Autistic people are now identified as a priority population for suicide prevention policy and practice. However, health and mental health professionals can lack confidence, training and resources to effectively support Autistic adults at risk of suicide. Our research program has involved collaboration with Autistic people to identify gaps in mental healthcare supports, develop lived experience led training for professionals, and co-develop adapted suicide screening and assessment measures. My talk will provide a broad overview of our research to date leading to the development of a new autism suicide prevention resource hub for healthcare professionals, which has included research collaboration with leading experts in the UK. Our goal is that this resource will provide health and mental health professionals with the skills and resources to enable them to better identify and support Autistic people with mental health concerns as well as risk of suicide.

Abstract: The effects of aerosols on the Earth’s energy balance since pre-industrial times (aerosol radiative forcing) has significantly and repeatedly dominated the uncertainty in reported estimates of global temperature change from the IPCC . The magnitude of aerosol radiative forcing of climate over the industrial period is estimated to lie between about -2 and -0.4 W m-2, compared to a much better understood forcing of 1.6 to 2.0 W m-2 due to CO2 . In this seminar, past efforts to quantify the range of possible aerosol forcings predicted from an aerosol-climate model that are caused by parametric uncertainty, and to constrain that forcing uncertainty through model-observation comparison using extensive aerosol and cloud-based measurements from ships, flight campaigns, satellites and ground stations, will be discussed. We find that despite a very large reduction in plausible parameter space and reasonable constraint on observable properties, the observational constraint based on this comprehensive set of measurements only partially reduces the range of aerosol radiative forcings from our model. In the NERC project ‘Towards Maximum Feasible Reduction in Aerosol Forcing Uncertainty’ (Aerosol-MFR), several key statistical challenges highlighted from this work are being addressed in order to improve the model-observation comparison process for uncertainty constraint. This includes optimising the way observational constraints are applied, designing new approaches for reducing error compensation effects and using the PPE to identify and characterise model structural errors. Preliminary results from the project so far will be outlined, along with further plans to tackle this important problem.

: Most published clinical prediction models are never used in clinical practice which leads to a huge gap between academic research and clinical implementation. Here, I propose a checklist to enable academic researchers to be proactive partners in improving clinical practice and to design models in ways that ultimately benefit patients. Over the years I have come to see academic papers not as ends in themselves, but as the beginning of the journey to clinical implementation, and I am frustrated with how little of my own work ever had clinical impact. I argue that you should outline the road to implementation whilst designing your prediction tool by thinking about what medical decisions they are making and how these tools can be used in routine practice. I will illustrate these ideas by discussing AI models from our work to find a minimally invasive alternative to endoscopy and looking at ways of assessing breast cancer survival rates after surgery that can be used in the clinic.

We are at a moment of extreme pessimism about data with news stories implicating social media and mobile phones in cyberespionage. To many this is a worrying state of affairs but are we worrying too much? In this talk I will argue that data openness and data-drive advertising are good things and are misunderstood. In particular data-driven advertising is not about controlling behaviour but involves targeting groups of people which brings economic benefits. Internet search data has been used to meet public health challenges such as providing insights into Zika and Ebola. I will argue we should be targeting the distribution of digital power rather than concerning ourselves with business models of particular companies.

Randomised controlled trials (RCTs) in education research have been carried out for over 100 years. Over the last 15 of these years their use has increased significantly. In this talk we examine the field of education research to address the key challenges faced by education trials today and possible solutions. Despite their growing use they have been subject to sustained and rather trenchant criticism from significant sections of the education research community. There are key areas in which RCTs require focus and improvement: in particular in recruitment and retention, implementation and outcome measures.

The Australian Antarctic Program Partnership (AAPP) is focused on understanding the nature and impacts of Southern Ocean Change. The Biogeochemistry Project, one of the seven complementary initiatives within the AAPP , combines observations, models and data syntheses to understand changes in the Southern Ocean carbon cycle. This work is undertaken in collaboration with other government agencies, national infrastructure programs, and academic institutions, and highlights the use of essential ocean observations and models to improve understanding and deliver impact. An overview of recent field programs will be presented, along with new work to quantify the uptake and storage of anthropogenic CO2 in the ocean, to validate estimates of ocean carbon export from autonomous platforms, and to improve model representation of air-sea CO2 exchange.

People will have increasingly heard the term Neurodiversity. Some may know what it means but many are still unsure or scared to ask. In my talk I try to explain the basics of Neurodiversity, dispell some common misconceptions and give some of my own experiences. I will also give you some ideas for how to accommodate Neurodivergent people and where to look for support.

Scott is an experienced battery scientist, science communicator, budding entrepreneur and Neurodiversity advocate. He has worked in academia, RTOs and an SME on a broad range of battery chemistries and applications. He is presently exploring his own ventures in a variety of sectors under the branding “Watts Up With…?”. Scott is Neurodivergent. He has Autism, Dyslexia and (pending diagnosis) ADHD . This combination of traits and experiences gives him a deep understanding of what it is like to be a Neurodivergent individual in academic/work environments.

This presentation examines the structural response, disassembly, and reuse potential of steel-timber shear connections. It includes results from experiments and numerical simulations under various loading conditions. A detailed account of the complete deformation response and the main mechanical parameters of the tested shear connections for conventional and slim steel-timber floors is presented. Non-linear finite element simulations were carried out to validate the main numerical parameters for steel, timber, and interaction characteristics, and then used for parametric investigations. Based on the results and observations, code-modified expressions for evaluating stiffness and load resistance were proposed within the ranges considered and validated against a collated database. A constitutive model was developed to predict the full load-slip response of shear connections, which can be adopted for discrete non-linear modelling of connectors. A reuse potential testing protocol was developed to evaluate performance after cyclic loading and reassembly, and a modified separation damage index was introduced to quantify the circularity of these systems. A sensitivity study for the tested shear connections and other practical configurations for steel-timber floors was also carried out for evaluating the circularity of such systems.

he Erdős-Ginzburg-Ziv theorem states that for any sequence of 2n-1 integers, there exists a subsequence of n elements whose sum is divisible by n. In this article, we provide a simple, practical O(nlog log n) algorithm and a theoretical O(nlog log log n) algorithm, both of which improve upon the best previously known O(nlog n) approach. This shows that a specific variant of boolean convolution can be implemented in time faster than the usual O(nlog n) expected from FFT -based methods.
