 I'm delighted to be here. I'm really just the warm-up act for our two great star speakers this evening and I hope we'll have a really good session. And so I'd like to add my welcome to this Open Minds event which I think is a really important kind of event to have at the moment because in our society and indeed across the world we're in a time of profound change. We see a lot of political change, a lot of economic change, social change, technological and ecological change. We've got all sorts of things, climate change, migration issues, changing patterns of crime, loss of trust in politicians and bankers, greater blame and scepticism of public services. We're actually dealing with quite a lot. So I think events like tonight which are trying to tackle some big global issues are really important. I'm not sure we're going to be able to solve crime in an hour, but we'll do the best we can. And the OU, as Susan has said, is trying to address some of these big problems and challenges that we face globally by really investing in areas of research. And there's a number of these. They include space science and innovation and international development. And the one that I'm particularly involved in is the one called Citizenship and Governance. And we're trying there to address some really big issues about what does it mean to be a citizen in today's societies and how do people claim citizenship? We see a lot of struggles around that, around the Middle East and people coming to the UK, for example, and other parts of Europe. And also thinking about the changing relationships between the market, the state and civil society, different ways of governing our society, making decisions, trying to create value for the public sphere. And also thinking about public leadership as well as a way to mobilise the attention and resources and values and purposes of people in order to produce a society which is hopefully fair and prosperous and has well-being at its core. So there are a lot of issues for public leaders, whether they are elected politicians, whether they're professionals and public servants, or whether they're civic and community activists. So that's very much the area that Citizenship and Governance is involved in. And as part of that work, we are really delighted and excited by the work that we're doing in the field of policing. And I'm just going to show you just the front page of our new website for the Centre for Policing Research and Learning. Nick, I'm going to mention Cypr in a minute, so don't worry. We're collaborating over a number of things. So, as Susan mentioned, we've set up this centre to look at policing. Now, policing is much wider than just crime. It's also about public order, public safety, a sense of confidence in society. And we're working with 12 police forces in the UK, large ones like the Metropolitan Police and Greater Manchester, much smaller and many rural ones like Gloucestershire or Dorset, and many in between and including the Northern Ireland Police Force and one of the Welsh forces. And that gives us a really good opportunity to do research in a variety of settings, which is really important to us. So we can really test out what works in different contexts, in different settings, in different organisational cultures. So that's really important to what we're doing. We're working in a highly collaborative way, so our aims, very like Cypr, actually, are to work with police, being questioning, being challenging, but also working shoulder to shoulder to really try and understand what are the problems that the police face, that communities face, and thinking about those designing research. And then thinking about how you use research as well. My background is as an organisational psychologist. So I'm actually really interested in how ideas and research evidence is used in practice and doesn't just stay as fancy words in policy documents. So the work we're doing through the centre with these 12 forces, we're looking at three strands of work around education, research and knowledge exchange. And I think this one will be around the education where we've got five stepping stones to try and help police in their professional development. We've got things, we've got a whole range of opportunities, if you like, from small, bite-sized pieces of learning, perhaps 10 minutes, perhaps 10 hours, right through to degree courses and PhDs for the police. And we've now got five police officers and staff undertaking PhDs through the centre. But in addition, we do a lot of research. I'm very pleased that the centre is multidisciplinary. It's really important if we're going to look at big global challenges that we stop being in particular disciplines and start working in an interdisciplinary way because many of the problems of society don't fall in particular disciplines. They require a multidisciplinary or an interdisciplinary approach. So we've got psychologists, sociologists, criminologists, engineers, computer scientists, all sorts of people working on a range of things from cybercrime. We'll hear about Hailey's project in social media and technology and leadership for public value. And we're also doing work in knowledge exchange as well and we have sick comments from police officers and staff. I also wanted to mention cyber as well because we're very pleased that the Open University is involved with cyber. And it's interesting that it's a mirror image type of consortium because it's 13 or 14 universities working with one police force. Whereas the centre that I've just spoken about is 12 police forces in one university and works with many of the same interests and we look forward to doing much more work together. I want to move on to introduce our speakers and to think about this issue about tackling crime. Maybe we should talk about tackling rather than solving crime because I'm not sure it'll ever go away. But we're in an interesting period I think where the formal statistics are going down in relation to crime but actually the nature of crime is changing and police are having to be more involved in a range of different activities including cybercrime, counter-terrorism and so on. And of course there still is traditional crime and Karen might say perhaps depressingly too much similar crime to the past. So I think some of the challenges of changing crime the changing technology which is actually influencing the relationship between the police and the public and with communities. So we're going to hear two really interesting talks. I know both of their work quite well so I'm really delighted to be able to introduce each of them. One a practitioner, one an academic both really committed to tackling real problems and issues in Scottish policing and Scottish crime. I'll introduce them both now and then invite Karen to come to the podium. I think a number of you will know Karen as the person who's set up the Violent Crime Reduction Unit here in Scotland and there've been any number of newspaper articles about her and what she's managed to achieve here but still I think some way to go she would probably feel in terms of Scottish society and I gather she's just taking on football crowds football sectarianism as an issue. But you don't have to talk about that if you don't want to. We're also very pleased that Karen last year accepted an honorary degree from the Open University and we hope she feels as we do that's real recognition of the work that she's been able to achieve for public service. So thank you very much Karen. Just before you come up to also introduce Hayley, Doctor Hayley Ness who works for the Open University and is a staff tutor involved in creating teaching materials and learning materials working also with tutors and students focused particularly on Scotland and also across all four nations and with a background in forensic psychology and forensic cognition very interested in face recognition and we've just been having a very fascinating topic about super recognisers who are people who are particularly good at recognising faces but what she's going to be talking about tonight is the public's use of social media and how that's affecting some police procedures. So I think we've got a stunning line up and I need to get out of here to give them all the time that we can. So Karen, over to you.
