'Cool' - Laurie Taylor traces the trajectory of the notion of ‘cool’ with Joel Dinerstein, Professor of English and American Studies at Tulane University, and author of a study which suggests it originated in American jazz clubs as a stylish defence against racism and cross fertilised with French existentialism and film noir.

Also, ‘cool shades’: Vanessa Brown, Senior Lecturer in the School of Art and Design at Nottingham Trent University, explores the enduring appeal of sunglasses as the ultimate signifiers of ‘cool’ in mass culture.

Serial killers: Laurie talks to Ian Cummins, Senior Lecturer in Social Work at the University of Salford, about the media and cultural responses to the child murders committed by Ian Brady and Myra Hindley two decades earlier. The Moors Murders were to provide an unfortunate template for future media reporting on serial killing, including the crimes committed by Peter Sutcliffe - the Yorkshire Ripper - as described in a new study by Louise Wattis, Senior Lecturer in Criminology and Sociology at Teesside University. Sutcliffe murdered 13 women in the North of England between 1975 and 1980. Dr Wattis discusses the way in which these crimes shed light on how we think about fear of crime, gender and serial murder and the representation of victims and sex workers.

Council estates: Laurie Taylor talks to Insa Lee Koch, Associate Professor in Anthropology at LSE, and author of a new study which explores the history of housing estates and the everyday lives of residents on one such estate in southern England. How did council housing turn from being a marker of social inclusion to a marker of abject failure? Also, the origins and symbolism of the ‘sink estate’, a term invented by journalists and amplified by think tanks and politicians. Tom Slater, Professor of Urban Geography at the University of Edinburgh, traces the usage of this term and the long-term impact of associating council estate residents with effluence and sewage. Revised repeat.

Land Struggles: From Bolivia to Britain, the way that land is owned and controlled is central to many contemporary inequalities and political battles. Laurie Taylor talks to Brett Christophers, Professor in the Department of Social and Economic Geography at Uppsala University, Sweden, about ‘the new enclosure’, a UK study into the appropriation of public land by the private sector – an astonishing two million hectares worth £400 billion – in recent decades. This ownership now forms the largest component of wealth in Britain and is the largest privatisation of a public resource in European history. Also, Penelope Anthias, Assistant Professor in the Department of Geography at University of Durham, describes the lives of indigenous people in Bolivia as they struggle to regain ancestral territory after a century of colonialism and state backed dispossession.

Laurie Taylor asks why so many Islamist extremists come from an engineering background. He talks to Steffen Hertog, Associate Professor of Comparative Politics at the London School of Economics, about a new study which finds that Islamist and right-wing extremism have more in common than either does with left-wing extremism, in which engineers are absent while social scientists and humanities students are prominent. Is there a mindset susceptible to certain types of extremism? They're joined by Raffaello Pantucci, Director of International Security Studies at the Royal United Services Institute.

Prison TV: Laurie Taylor considers the therapeutic role of television in the modern day jail. He talks to Victoria Knight, Senior Research Fellow at De Montfort University, Leicester, and author of a new study examining the way in which TVs in cells manage the everyday life and emotions of prisoners; helping deliver both care and control. In addition, she offers insights into how technology in prison is evolving globally. They're joined by David Wilson, Professor of Criminology at Birmingham City University.

Also, prison 'blues': BB King, the African American Blues musician, died on 14

Organised crime in the UK - how has it changed? Professor Dick Hobbs, joins Laurie Taylor, to discuss his work on 'Lush Life', a rich, ethnographic study into 'Dogtown', a composite of several overlapping neighbourhoods in East London. Looking behind the clichéd notions of criminal firms and underworlds, he finds that activity which was once the preserve of professional criminals has now been normalised. He invites us to consider whether or not the very idea of organised crime has become outdated in a predatory, post industrial world in which many fight, by illegal as well as legal means, to survive on the margins. Also, the presence and activities of Mafia style crime both in Italy, as well as in the UK. Dr Felia Allum, a Lecturer in Italian History and Politics, discusses how Italian organised crime functions outside its territory of origin. Revised repeat.

Also, beauty politics in the Neoliberal age. Ros Gill, Professor of Social and Cultural Analysis at City University, discusses the ways in which women are required to be 'aesthetic entrepreneurs', maintaining a constant vigilance about their appearance. They're joined by Rachel Wood, Research Associate in the Department of Psychology, Sociology and Politics at Sheffield Hallam University. Revised repeat.
