Fri 23 May 16:00: WalkEar: Estimating ground reaction forces and gait parameters from commodity ear-worn wearables
Gait is a key health metric, sometimes described as the sixth vital sign. Temporal, spatial and kinetic gait parameters are valuable in enhancing sport performance and early health diagnostics of health conditions such as Parkinson’s disease. Full gait assessment requires a gait clinic and existing wearable gait tracking systems typically measure isolated subsets of parameters tailored to specific applications. This is useful when the condition to be monitored is known but fails to offer a comprehensive view of an individual’s gait traits when their pathology is unknown or changing, or a general assessment is required. To support holistic walking gait tracking, we introduce WalkEar a sensing platform designed to simultaneously track a set of walking gait parameters using commodity ear-worn wearables. WalkEar operates by detecting gait events using them to derive temporal gait parameters and segment the IMU data. We then use regression techniques to predict kinetic gait parameters and estimate the full vertical reaction force. Each parameter is calculated on a step-to-step basis to enable assessment of gait variability and asymmetry. We developed an earbud prototype and collected data from 30 subjects using gold standard force plates and instrumented treadmill ground truth. Experiments show strong agreement between our system and the ground truth showing the promise of using ubiquitous earbuds for continuous gait monitoring.

Tue 20 May 15:30: Building Organizational Resilience with AI Malfunction Drills
AI systems malfunction — and when they do, a human is typically held responsible for identifying and correcting this malfunction, yet they are rarely trained to do so. In this talk, I will advocate for AI malfunction drills: training exercises that would expose participants to simulations of realistic AI system failures in a controlled setting. These exercises would provide a safe environment for the users and operators of an AI system to practice detecting and resolving AI malfunctions.

Wed 21 May 11:30: Autism in Midlife and Older Age
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.

Tue 27 May 13:10: “Why we should stop talking about ‘Christians’ in connection with the New Testament”
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.

Wed 18 Jun 17:00: Towards the Development of a National Autism Suicide Prevention Resource Hub
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.

Tue 24 Jun 14:00: The statistical challenges in tackling persistent climate model uncertainty through model-observation comparisons. https://teams.microsoft.com/l/meetup-join/19%3ameeting_OWJjY2ViNjktOWZjMS00NGJmLWI5MTUtNTYxM2E5MTgyMTQ1%40thread.v2/0...
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.

Tue 07 Oct 19:15: All models are wrong and yours are useless: making clinical prediction models impactful for patients
: 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.

Mon 03 Nov 19:00: Benefits of data openness in a digital world
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.

Wed 26 Nov 19:15: 100 years of educational trials – no significant difference?
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.

Fri 16 May 15:00: Structural Response and Reuse Potential of Steel-timber Shear Connections
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.
