Lunch Hour Lectures - Spring 2011 - Audio

Spring 2011 - UCL's Lunch Hour Lecture Series is an opportunity for anyone to sample the exceptional research work taking place at the university, in bite-size chunks. Speakers are drawn from across UCL and lectures frequently showcase new research and recent academic publications. Lunch Hour Lectures require no pre-booking, are free to attend and are open to anyone on a first-come, first-served basis.

  1. EPISODIO 1

    Great 2 meet u IRL :-) Twitter and digital identity - Audio

    Is Twitter an ephemeral technology, consisting of mundane chat about people's personal lives? Or can a study of its use help us to understand how we express our identities on and offline? Can Twitter be used for professional or academic activity, and should we try to separate our public and private digital personae? This lecture will address such questions, with the aid of slides of 140 characters and live tweets from the audience at UCL and on the internet. Authors: Claire Warwick (UCLDH), @clhw1, Melissa Terras, @melissaterras, #melissaterras (UCLDH); Claire Ross, @clairey_ross (UCLDH); Anne Welsh, @AnneWelsh (UCLDH) This lecture marks the 5th anniversary of Twitter on 21 March.

    Would you give your right arm to protect your heart? - Audio

    During a heart attack the cells that make up the muscle of the heart are subjected to a restricted blood supply, this is usually caused by a blood clot or a narrowing of the coronary arteries. If the blood supply is not restored quickly it will result in the death of the heart muscle, and to protect against this injury, blood clot prevention drugs, inflating balloons and artery bypass surgery are all used to restore blood flow as quickly as possible. Paradoxically, however, the very act of restoring such blood flow can also cause a significant amount of heart cells to die. In this lecture, Professor Yellon will discuss why this injury occurs, how simple techniques such as inflating a blood pressure cuff on the arm can protect the heart against such injury, and how developments in UCL’s laboratories are already benefiting patients at risk.

    Should the brain be left to neuroscientists? - Audio

    Since the 'decade of the brain' in the 1990s an increasing range of previously taboo subjects have been examined by neuroscientists. These include autobiographical memory, aesthetics, love and of course consciousness itself. The rise of imaging techniques which provide engaging pictures of brain activity have added to the appeal. Of course plenty of other discplines within the arts as well as science put the brain at the heart of their project. But how effectively has neuroscience integrated these other approaches into its work? And should the direction of brain research be left to scientists anyway? This lecture marks Brain Awareness Week 14-20 March.

    Genetic testing in the 21st century: Should we screen the human embryonic genome before implantation? - Audio

    In preimplantation genetic diagnosis (PGD), embryos are created by IVF and cells removed from these embryos for genetic analysis. Until recently, testing was solely for the disease the couple carried. The use of array-comparative genomic hybridisation and single nucleotide polymorphism arrays has entered the PGD arena. These techniques allow all chromosomes and many genes to be examined. The analysis of the whole genome prior to implantation brings ethical concerns. Will healthy couples opt for PGD to select their ‘best’ offspring? This lecture marks International Women’s Day - 8 March

    Sex, Drugs, the Internet and Juries - Audio

    Is it true that juries rarely convict defendants in rape cases and are more likely to convict ethnic minority defendants than White defendants? And why can’t jurors resist going home at night and googling the defendant or tweeting about the case – against the express instructions of the judge. This lecture reveals the truth behind a number of widely held beliefs about juries in this country and examines why the internet may now be the biggest threat to our jury system.

    The origins of the ‘ndrangheta of Calabria: Italy’s most powerful mafia - Audio

    On 15 August 2007, six young men with origins in the Italian region of Calabria were ambushed and murdered in the German steel town of Duisburg. This was northern Europe’s St Valentine’s Day massacre, the worst ever mafia bloodbath outside Italy and the United States. Suddenly, journalists across the globe were struggling with what the New York Times called an ‘unpronounceable name’: ‘ndrangheta (en-drang-get-ah.) In the 1990s, the ‘ndrangheta placed itself in a leading position in the European wholesale cocaine market by dealing direct with South American producers. It is now thought to be the wealthiest and most powerful of Italy’s major criminal brotherhoods. But how, when, and why did it first emerge?

    Sex education via the media: Promises and pitfalls - Audio

    This lecture will draw on Dr Boynton's experiences of delivering sex advice through the media - as an agony aunt in magazines and online ,and for education radio and TV such as Channel 4's The Sex Education Show. Drawing on research on media advice giving internationally Petra will highlight where media gets it wrong and right, and how we can inform sex education media for young people and adults through evidence based practice and research.

    Will robots take over the world? - Audio

    2011 is the 90th anniversary of the robot, first imagined as a character in a play, performed in Prague in 1921. It is also the 50th anniversary of the first use of robots in industry with the robot ‘Unimate’ for General Motors in 1961. Since the origin of robots they have undergone a number of transitions from the popular idea of the robot as a domestic, a vision popular from fiction such as the 1970's cartoon ‘The Jetsons’, to the last fifteen years imagining robots, not just for work, but to act as companions, exercise coaches for the elderly or stroke patients, and assistants for children with autism spectrum conditions. This lecture will explore the history of the robot, and how it has changed and been re-imagined in fiction and labs over the last 90s years.
