Thinking Allowed

Grandfathers today: Laurie Taylor talks to Ann Buchanan, Senior Research Associate in the Department of Social Policy and Intervention at the University of Oxford, about the changing nature of grandfatherhood. She brought together a team of international scholars, from Finland to South Africa, who found that grandfathers were re-inventing themselves into a new, caring role in the wake of increased divorce, long parenthood and more active, elder lives. They're joined by the writer and broadcaster, Michael Bywater.Dementia carers: Simon Bailey, Research Fellow in Sociology at the University of Manchester, talks about the findings of three National Health Service wards and one private care home in England. Staff are expected to provide person centred care which mitigates the loss of insight, personality and capacity associated with dementia. But, as his research demonstrates, direct care staff have only limited training and remuneration to deliver such quality care.Producer: Jayne Egerton.

Get out of my room! A social history of teen bedrooms in America. Laurie Taylor talks to Jason Reid, Lecturer in History at Ryerson University who charts the evolution and meaning of this sanctuary for adolescent self expression.They're joined by Sian Lincoln, Senior Lecturer in Media Studies at Liverpool John Moores University who has explored the role of bedrooms in the lives of young British people.Skydivers & dangerous sports: James Hardie-Bick, Senior Lecturer in Sociology and Criminology at the University of Sussex, discusses the motivations, behaviours and experiences of those who voluntarily engage in high-risk activitiesProducer: Jayne Egerton.

The production of money: how to break the power of the banks. Laurie Taylor talks to Ann Pettifor, Director of Policy Research in Macroeconomics (PRIME) and author of a provocative new book which asks how money is created and whose interests it serves. Countering the notion that it's a neutral medium of exchange in which bankers are merely go betweens for savers and borrowers, she says we can claim control over money production and avert another financial crisis. But how might we go about it? Diego Zuluaga, Financial Services Research Fellow at the Institute of Economic Affairs, offers a contrasting perspective. Producer: Jayne Egerton.

Squatting: Laurie Taylor discusses the first popular history of squatting in Europe and North America. Alexander Vasudevan, Associate Professor of Human Geography at the University of Oxford, drew on extensive archival research to retrace alternative forms of housing from Copenhagen's Christiana 'Free Town' to the Lower East Side of Manhattan. He's joined by Lucy Finchett-Maddock, Lecturer in Law at the University of SussexAlso: 'Streaking', 'mooning' and 'flashing'. Barbara Brownie, Senior Lecturer in Visual Communication at the University of Hertfordshire, explores the many meanings of public disrobement, from the playful to the criminal.Producer: Alice Bloch.

Platform Capitalism: How the most powerful tech companies of our time are revolutionising the global economy. Laurie Taylor talks to Nick Srnicek Lecturer in International Political Economy at City, University of London, and author of a new study which critically examines how companies ranging from Google, Amazon and Microsoft to Facebook, GE and Airbnb, are turning into platforms: businesses that provide the hardware and software foundation for others to operate on. This transformation in how companies operate offers new possibilities for consumers, but also represents an arguably troubling monopoly control over both distribution and production. How did Platform Capitalism originate, what are its merits - as well as its dangers - and does it have an infinite future? Ursula Huws, Professor of Labour and Globalisation at Hertfordshire School of Business and Andrew Leyshon, Professor of Economic Geography at the University of Nottingham, also join the discussion.Producer: Jayne Egerton.

Terrorism: does it ever work?

Claudia Aradou, Reader in International Politics at Kings College, London charts the chequered history of a form of communication which arose in the context of the Cuban Missile Crisis and the Cold War. Producer: Jayne Egerton.

Vertical cities: Laurie Taylor explores the increasing segregation of cities by height. Stephen Graham, Professor of Cities & Society at Newcastle University, ponders 'class war from above'. His exploration of the built environment around the world, both above and below ground, finds that the wealthy have gone upwards; into "islands" and "archipelagos" of residential towers, hotels, private clubs, roof gardens, restaurants, swimming pools, even heliports. They enjoy fresher air, commanding vistas, safety from crime and speedy travel. Privileged Chinese citizens retreat to air conditioned citadels in the sky; wealthy Thai commuters enjoy the Skytrain, Bangkok's elevated railway for the fortunate few. Graham lays out a landscape where architecture reflects and reinforces divisions with ever greater brazenness. India's property boom. In recent years, India has seen a sudden and spectacular urban transformation. Gleaming business complexes encroach on fields and villages. Giant condominium communities offer gated security and pristine pools. Spacious, air-conditioned malls have sprung up alongside open-air markets. Llerena Guiu Searle , Assistant Professor of Anthropology at the University of Rochester, interviewed estate agents, investors and developers, documenting the new private sector partnerships and practices that are bringing prosperity, but also making India's cities ever more inaccessible to the urban poor Producer: Jayne Egerton.

They were joined by Diane Coyle, Professor of Economics at the University of Manchester. Juliet Webster, Director of Work and Equality Research at the LSE, explores the brave new world of virtual workers - characterised by short contracts, flexible working hours and the blurring of boundaries between work and free time. Producer: Jayne Egerton.

Health divides: Where we live can kill us. Americans live 3 years less than their counterparts in France and Sweden. Scottish men survive 2 years less than English men. Across Europe, women in the poorest communities may live 10 years less than those in the richest. People who live just a few miles apart can have gaps in life expectancy of up to 25 years. Laurie Taylor talks to Clara Bambra, Professor of Public Health Newcastle University Medical School, whose research draws on international case studies to examine the cause of these health inequalities and to consider what changes would be needed so that geographical location need not be a matter of life or death. Global health: moving beyond metrics - From maternal mortality to malaria, statistical methods are used to measure sickness, injury and suffering across the world. But Vincanne Adams, Professor of Medical Anthropology at the University of California, argues that such well-intentioned 'evidence based' interventions often fail. Drawing on rich case histories from countries including Nigeria and Haiti, she argues that we are missing other ways of knowing and tackling global health problems.Producer: Jayne Egerton.

The 'age of noise': How a preoccupation with unwanted sounds came to characterise modernity. The 20th century saw the expansion of cities and technological change. The sounds of motor cars, vacuum cleaners and gramaphones filled the air, leading social commentators to forecast the end of civilisation and a breakdown in mental health. Did noise provide people with a way of talking about their social anxieties? Does it still serve this function today? Laurie Taylor talks to James Mansell, Assistant Professor of Cultural Studies at the University of Nottingham and Marie Thompson, Lecturer in the School of Film and Media at the University of Lincoln. British drinking and the night time carnival. William Haydock, Visiting Fellow in the Faculty of Health and Social Sciences at the University of Bournemouth, argues that our alcohol consumption is peculiarly 'carnivalesque', combining ritual with risk taking and spectacle.
