Lovelace Lecture: Learning and Efficiency of Outcomes in Games

Series
Strachey Lectures
Embed
Éva Tardos, Department of Computer Science, Cornell University, gives the 2017 Ada Lovelace Lecture on 6th June 2017.
Selfish behaviour can often lead to suboptimal outcome for all participants, a phenomenon illustrated by many classical examples in game theory. Over the last decade we developed good understanding on how to quantify the impact of strategic user behaviour on the overall performance in many games (including traffic routing as well as online auctions). In this talk we will focus on games where players use a form of learning that helps themadapt to the environment, and consider two closely related questions: What are broad classes of learning behaviours that guarantee that game outcomes converge to the quality guaranteed by the price of anarchy, and how fast is this convergence. Or asking these questions more broadly: what learning guarantees high social welfare in games, when the game or the population of players is dynamically changing.

Lionel Barber discusses the changing media landscape, the impact of social media, and how the award-winning Financial Times continues to respond to the digital age.
The FT's editor warns about fake news and refers to past propaganda - subjects he will address on Saturday 16 September 2017 at the Alumni Weekend in Oxford (book online to secure your place at this session).

In this wide-ranging podcast interview, Barber gives his perspective on current affairs, from the Europeans having the upper hand in Brexit negotiations to the theatre of Donald Trump's presidency.

Kate Binnie: First and Last Breath soundscape

Series
Nuffield Department of Clinical Neurosciences
Embed
A soundscape about breathing as a barometer of our state of mind and physical health.
Working as a therapist with people towards the end of their lives, and with a particular interest in the power of breath regulation as a tool for emotion regulation and symptom control, I started making this 'breath-voice collage' by recording an 'anchor' breath, which would act as a metronome throughout the piece. This was the sound of a heartbeat timed to a 'coherent' breath. This breath, commonly used by meditators and yoga practitioners, is timed at five breaths per minute, and has been shown to help people recover from trauma and anxiety disorders, and to relieve physical and psychological pain (see Brown & Gerberg 2012) and I often use this in therapy.

I then interwove recordings I had saved on my iphone over the years…. my children as babies, their sleeping breaths, an old recording of my partner and I singing our child to sleep. I also recorded the breathing of a patient with chronic obstructive pulmonary disease (COPD) and his words, describing how he felt about his loss of breath. Lastly, I used a recording of my father’s breathing during his last days in the hospice. During that time, the sound of his breath was extremely important, precious and fragile because we knew it would end. In the liminal phase between life and death I sang to him the songs he loved. The Skye Boat Song was one of his favourites….

Kate Binnie is a music therapist, yoga and mindfulness teacher with an Msc in Palliative Care and a special interest in the relationship between breath and emotion regulation, and how this can be used clinically in the management of refractory breathlessness across advanced disease.

Recent Developments in Reading Assessment in the USA National Assessment of Educational Progress (NAEP): An Analysis of Conceptual, Digital, Psychometric, and Policy Trends

Series
Department of Education Research Seminars
Embed
OUCEA Annual Lecture, 25th May 2017, Ashmolean Museum
In his presentation, Professor David Pearson, who serves as the Chair of the Standing Committee on Reading for NAEP provided an update on recent innovations in the conceptualisation and operationalisation of NAEP Reading. He explained that the Standing Committee provides oversight on passage selection, item development, and scoring to the Educational Testing Service and discussed the conceptual bases for new digital initiatives, as well as the progress made to identify and resolve challenges to an entirely new digital delivery of NAEP Reading. Professor Pearson also commented upon NAEP reading developments in relation to those recently undertaken by PIRLS and PISA.
Professor Maggie Snowling, President of St John's College, University of Oxford acted as the discussant and focused her presentation upon the reasons and causes of poor reading comprehension. She explained that poor comprehenders have good decoding but they do not use context to support word reading as well as typical readers do.
