How computers have changed the way we do physics - Structure in complex systems

Series
Theoretical Physics - From Outer Space to Plasma
Embed
The power of available computers has now grown exponentially for many decades. The ability to discover numerically the implications of equations and models has opened our eyes to previously hidden aspects of physics.
In physics, "complex systems" are systems of many similar interacting parts, such as the interacting atoms that make up a solid or liquid, but also interacting organisms in an ecosystem, or interacting traders in the stock market. This lecture will discuss how recent advances in modeling and computer simulation have allowed us to apply physics-style approaches to these previously challenging real-world systems to learn about such things as the spread of diseases, the flow of traffic or the structure of entire human societies.

How computers have changed the way we do physics - Chaos and climate change

Series
Theoretical Physics - From Outer Space to Plasma
Embed
The power of available computers has now grown exponentially for many decades. The ability to discover numerically the implications of equations and models has opened our eyes to previously hidden aspects of physics.
In this lecture, Myles Allen addressed how computers have transformed our understanding of the role of chaos and exponential error growth in weather forecasting; and our understanding of how climate change is impacting regional weather. He showed how research in Oxford Physics, made possible by high-end computing, is demonstrating the crucial role of eddies in controlling ocean climate; and how the probability of extreme weather events may respond to rising greenhouse gas concentrations. He concluded by throwing out a more controversial suggestion that super-computers haven’t really contributed very much to the problem of predicting century-timescale changes in global average temperature, however much they may have contributed to understanding the regional implications of large-scale warming.

Variation across the human genome: a tricky balancing act in human health and disease

Series
NDM Public Engagement
Embed
Genetic variation can have opposing effects on human disease, where the benefits of a protective variant against one disease can increase the risk of another.
I provided four examples of the Yin/Yang of genetic variation in human health and disease:

CCR5Δ32: This variant protects against HIV-1, but associates with risk of symptomatic West Nile Virus infection.
HLA-B*57: this is an HLA class I allele of the highly polymorphic HLA-B gene that confers protection against HIV-1, but associates with risk of psoriasis and abacavir hypersensitivity.
HLA-C expression levels: complex variation outside of the protein coding region of the HLA-C gene determines HLA-C expression levels, where high expression associates with protection against HIV-1, but it also confers risk of Crohn’s Disease and graft vs. host disease after transplantation.
Killer cell immunoglobulin-like receptors that confer activating states: These complex genotypes confer protection against KSHV infection, but among subjects with these genotypes who do become infected with KSHV, there is an increased risk of Kapok’s sarcoma.

Social and emotional early development: A programme to develop children’s social skills and help prevent bullying

Series
Department of Education Public Seminars
Embed
Daniel Muijs, Professor of Education at the University of Southampton, gives a talk for the Department of Education public seminar series.
While dealing with bullying when it occurs in schools is extremely important, we are increasingly finding that prevention is better than cure. Ensuring that schools create a culture in which all pupils develop empathy and social skills, especially among so-called ‘bystanders’ (those pupils who are neither the bully or the bullied but whose behaviour can strongly influence both) may therefore help to prevent future bullying behaviours.
The Social and Emotional Early Development (SEED) programme was developed as an intervention to improve the social and emotional skills of primary school age children and build their resilience and empathy, resulting in more positive social interactions. The programme is based on principles of social and emotional learning, teaching thinking skills and gamification, and consists of ten discreet activities which encourage reflection through collaborative group work, prompted by a scenario depicted through a cartoon.
In this presentation we will present the programme which was initially run in three local authorities in England, and look at its impact on pupils’ behaviours and personal and social development. To do this we used a quasi-experimental design in which schools were randomly assigned to receive the intervention at different times.

Intravenous anaesthesia on Turner's High Street

Series
TORCH | The Oxford Research Centre in the Humanities
Embed
Dr Alessia Pannese explores a painted documentation of a relatively little known event in Oxford local history: the first intravenous anaesthesia during this TORCH Bite-Size talk at the Ashmolean Museum LiveFriday
The introduction of anaesthesia in medical practice is generally attributed to American dentist William Morton, who gave a public demonstration in Boston, Massachusetts, in 1846. However, recent research indicates that a crucial attempt was carried out by apothecary Robert Boyle in Oxford almost two centuries earlier

Migration through marriage: Analysing struggles around mobility and its control in the European border regime

Series
International Migration Institute
Embed
An ethnographic border regime analysis showing that the governing of migration remains an attempt to control rather than effecting a total control of movement, and that marriage becomes an important strategy for migrants' mobility
According to article 16 of the Universal Declaration of Human Rights, 'men and women of full age, without limitation due to race, nationality or religion, have the right to marry and to found a family'. This should entail that citizens from so-called 'third countries' married to a citizen of an EU member state also have the right to enter the Schengen area in order to join their partner, regardless of their social background and resources. However, states intend to regulate migration and during the last decade 'marriage migration' has become a specific target of control. One can observe an increasing problematisation and politicisation of 'marriage migration' – especially from Muslim countries – which led to more restrictive policies towards this group of migrants, for example through required language certificates or verifications of genuine marriages.

In order to analyse the struggles around mobility and its control in the context of 'marriage migration', I carried out multi-sited ethnographic research in Morocco and Germany. In the sense of a 'studying through' (Shore/Wright) I conducted interviews in institutions implementing migration policies, followed different state and non-state actors that are part of the border regime and studied the practices of migrants who attempt to use this legal opportunity for migration. This ethnographic border regime analysis (Transit Migration Research Group) shows that the governing of migration remains an attempt to control rather than effecting a total control of movement, and that marriage becomes an important strategy for mobility through which migrants exercise their agency in order to cross borders and realise their aspirations.
