BBC coverage of Hull City of Culture will be extensive across 2017. At its very start, the award-winning poet Sean O'Brien reflects upon why his native city, its waterscape and landscape, have inspired poets past and present.

The programme features a specially commissioned new poem from Sean - a three-part memory-piece, which is also a love-song for Hull, its surroundings and their metaphorical resonance:

........The great void

Awaiting the signal to flood, is a kind of belief

Yet also that when the world ends

Through the estuary's mouth and the saw-toothed marriage

Sean also celebrates the work of poets who have made the city their home: Andrew Marvell, a line from whose 17th Century poem, To His Coy Mistress, gives this programme its title; Philip Larkin, Stevie Smith and others. He brings in an eclectic range of music, including his personal favourite, Dirty Water, by local band The Fabulous Ducks.

He hears from the Hull-based geographer Chris Skinner, and poet Sarah Stutt.

Starting with memories of digging holes in the garden of the house where he grew up, via flood-cellars, culverts and drains, the smaller river Hull and the great estuarine river Humber itself, this highly-textured programme culminates with Sean at the top of the disused lighthouse at Spurn Point, gazing out into the North Sea.

This hospital based youth violence work is taking place in the four London major trauma centres and Producer Sue Mitchell was given exclusive access to follow what happens. The charity, Redthread, now has teams in each of the trauma centres and their youth workers will be alongside victims from the point that they walk, or are stretchered, in. They're away from their communities and alienated from peers and this surreal period - 'the teachable moment,' as it's known - is seen as being an effective time because the young person is vulnerable, shocked and forced to confront assumptions of invincibility.

Becky Calnan is a Redthread team leader at one of the London trauma centres and allows listeners to follow her work with nineteen year old Liam. He's been attacked on the street and turns up at Accident and Emergency with blood soaking into his coat and trousers. He tells her that he's been punched, kicked and stamped on as he was making his way to court for a scheduled appointment. She knows him already: just months earlier he was stabbed in his legs in a planned attack. Becky's been working with Liam ever since. His latest injuries don't surprise her: "He doesn't eat properly; he doesn't sleep as he's out at night, and he's paranoid because of how he's living: this all feeds into making these incidents much more likely to happen."

Liam tells listeners about his life of court appearances, street violence and lack of ambition. He traces the start of his problems back to 2010, when he moved to a new area of London with his Mum and sisters. He knows he could make something of himself if he puts his mind to it, but there's too much daily pressure for him to even try: "I don't know what can happen next. There are young youth running around with big knives and my Mum and Nan are scared. I'm not scared. I spat blood on them when they attacked me." But Liam's bravado cracks slightly as he acknowledges the work that Becky's doing: "She's helped me, I do appreciate that. If there are things I need to get off my chest she listens and she doesn't judge me. I don't have anyone else like that to talk to."

For Redthread the work is aimed at interrupting the cycle of violence which all too often sees the victim become the perpetrator. Liam describes being stabbed, jumped on and other attacks with a calm that would be more normally placed describing a shopping trip, say, not repeated street violence. He thinks he will end up dead unless he can change, but it's a hard task. Alongside Liam, Becky is helping others admitted every day. There's George, stabbed as he sat in his car, there are two victims who have yet to regain consciousness and a youngster who appears to have been paralysed in an attack. His long hospital stay provides a good opportunity to both tackle any possible acts of retribution and to begin considering the changes as he adapts to a very different life.

Redthread's hospital programme launched in 2006 and the idea has been in play in America for longer. There is an international network of hospital based intervention programmes and the idea is gaining ground, with Nottingham and Basildon being the latest areas for this approach. In London alone there were more than 1,236 victims of knife crime under the age of 25 in the year ending April 2016 according to the Metropolitan Police. The workers are called as ambulances are en route and will be there from the start, getting alongside the young person and helping them navigate the hospital system. They're trying to build the kind of relationships which many of these young people won't have had in their communities and the organisation also offer gang exit work and mental health support.

Dr Emer Sutherland, consultant clinical lead for the Emergency Department at King's College Hospital, said: "We set up the scheme at King's because we wanted to do more than just patch young people up and send them on their way. Hospitals have a unique opportunity to help try and stop the victim-perpetrator cycle. This is why talking to young people, at this key moment in their lives can help steer them away from the world of gang violence many find themselves in." Once they're in hospital they have a very private space for very private conversations: "Pain in some ways is a great mind opener.

"It's so powerful to the medical team, we can remember before we had Red Thread, we would see some of these young people who come in with trivial injuries and then come back with more severe injuries. We see youth violence as like any other disease, so we might see them on their way to school when they've been mugged or beaten up, then what could happen is they could join a gang to try and make them safe, even though the exact opposite is the case, then we see them going from stabbed in arms or legs to being quite viciously targeted and very vicious attacks - we find those very worrying.

John Toal meets former death-row inmates Sunny Jacobs and Peter Pringle at the retreat they have set up in rural Ireland to offer restorative treatment to other victims of wrongful conviction in order to help them back to a normal life.

Peter Pringle was sentenced to be hanged in Ireland in 1980. Sonia 'Sunny' Jacobs was sentenced to the electric chair in the United States in 1976. Sunny was accused of killing two police officers at a highway service area in Florida. Peter was accused of killing two police officers in rural Ireland during a botched bank robbery. Both had their sentences commuted to life and were later exonerated of their crimes. Peter and Sunny spent over 15 years each in prison for crimes they didn't commit.

After their release, life in the outside world was tough. They struggled to re-integrate into society. Practical things like crossing roads, opening doors or even being touched joined a long list of everyday challenges. Neither could escape the feeling that they had re-joined a society that had moved on without them.

In 1998 Peter heard Sunny give a talk about her death-row experience. Traumatised by her story and shocked by how similar their experiences were, Peter offered to drive Sunny to her next speaking engagement and their relationship grew from there.

Now married, Peter and Sunny run the Sunny Centre in rural Connemara, a retreat for people from around the world who have been wrongfully convicted and who are trying to retrace a path back into normal life.

For this programme, John Toal travels to the depths of the Irish countryside to hear Sunny and Peter's story. He hears how a combination of yoga, meditation, healthy food and the freedom to share their experiences with people who have been through similar trauma can assist those exonerated of dreadful crimes on their path back to normality ...and whether or not an exoneree can ever truly feel free again.

Poet Mab Jones explores the concept of 'Hiraeth' in the poetry of Wales and further afield

Hiraeth, a central theme of Welsh language poetry and song, is a feeling of something lost, a long time ago, whether national identity or a once-important language.

But if the English don't have a word for it, does that mean they don't feel it, or that they don't need it? For some, like Mab's former Professor at Swansea, M Wynn Thomas, 'hiraeth' can function as a default nostalgia button, and a dangerous tendency to believe things were better in the past. It's an experience characteristic of the powerless, the dispossessed; it's the signature tune of loss, but is this hopeless and persistent longing holding this small nation back?

Mab Jones is a poet and performer both humorous and deeply serious. She stands outside the Welsh language tradition, claims she doesn't feel hiraeth (not for Wales anyway - possibly for Japan), and for Radio 4 questions and pokes at the concept, visiting the National Eisteddfod for the first time in an attempt to put her finger on exactly what it is. Exploring the concept through poetry that expresses it, from the poets Menna Elfyn and Ifor ap Glyn she hears poems and songs that deal with aspects of Welsh history that might explain the continued existence of the word in Welsh - forced removals from much loved homes through industrialisation and military eviction. And she talks to writers who live between two worlds and struggle with a sense of belonging: Pamela Petro, an American writer who fell in love with the landscape of Wales in her twenties, and Eric Charles Ngalle, a Cameroonian poet and refugee, who made a life in Wales while unable to turn his mind to his original home, and the trauma that made him leave his family aged 17.

In the Jim Crow era of racial segregation, travelling in the United States was fraught with difficulties if you were black. At best it was inconvenient, as white-owned businesses refused to serve African American motorists, repair their cars or offer them hotel accommodation. At worst, travel could be life-threatening if you walked into the wrong bar in the wrong town.

That's why in 1936 Victor H Green, a Harlem postal worker, published the first edition of The Green Book. The guide listed hotels, restaurants, bars and service stations which would serve African Americans and was an attempt, in Victor Green's words, "to give the Negro traveller information that will keep from him running into difficulties and embarrassments". 'Embarrassments' seems rather a tame word for the outright hostility and physical danger which many black travellers experienced in segregation-era America. The Green Book became a catalogue of refuge and tolerance in a hostile and intolerant world.

Alvin Hall hits the highway, Green Book in hand, to document a little-known aspect of racial segregation: the challenges - for mid-20th century America's new black middle class - of travelling in their own country. Alvin's journey starts in Tallahassee, Florida, where he was born and raised, takes him through Alabama and Tennessee and concludes in Ferguson, Missouri.

The guide ceased publication soon after the passing of the Civil Rights Act in 1964. But, as Alvin discovers in Ferguson, many African Americans still feel far from safe as they drive. Alvin asks whether the Green Book ceased publication too soon.

Bobby Friction has started to realise that his day-to-day online activities are not only being monitored but in some senses manipulated. How often he interacts with specific friends, pages or sites sculpts and filters everything and everyone he comes into contact with online. Since the Brexit vote and the US election these bubbles have become a really big issue - with talk of fake news, post-truth politics and online communities increasingly divided.

The domestic challenge facing Britain's biggest secret intelligence service. What's stopping members of the ethnic minorities from playing a key part in Britain's spy network: discrimination, loyalty or simple old-fashioned prejudice? DJ Nihal Arthanayake, Five Live and Asian Network presenter, gets rare access to GCHQ, the government's secret communication headquarters in Cheltenham Spa. He talks to staff from the black, Asian and ethnic minorities and hears from members of those communities outside about their attitude to the intelligence-gathering organisation. A report leaked to the Sunday Times six years ago suggested that black and Asian intelligence officers were concerned about there being a racist culture. If GCHQ's workforce was truly representative of Britain's ethnic makeup, then 12 per cent would be black, Asian or from other ethnic minorities, but it's not even a quarter of that. Can the organisation change?

Is boredom under threat? There are more TV channels than we can count, Smartphones keep us engaged around the clock, and the constant white noise of social media coerces us to always 'interact'. In fact, there is so much to stimulate our everyday lives in this digital age that we need never be bored ever again. So do we still need to be bored? And what would we miss if we did eliminate boredom completely from our lives?

The happily bored Phill Jupitus takes a creative look at our attitude to this misunderstood emotion. He will examine what boredom is, and how it has influenced our leisure time, our workplaces, our creativity and our evolution. Phill will examine its impact on comedy, art, music, and television, taking us from punk to prison, from J. R. R. Tolkien to Sherlock Holmes, from Danish sex clubs to London's 'Boring Conference'.

This will be a lively look at the simple, very real and essential emotion of boredom, and a stout defence of the right to sometimes just sit down and do nothing.

Interviews include - the Reverend Richard Coles, the writer Natalie Haynes, the artist George Shaw, the comedy writer & producer Robert Popper, the psychologist Peter Toohey, the punk musician Gaye Black (formerly of The Adverts), the psychologist Sandi Mann, the BBC newsreader Simon McCoy, Dr Teresa Belton and the social media entrepreneur Jodie Cook.

Can a Shaman cure writer's block? David Greig goes on a very personal quest in an attempt to find out.

David Greig is one of our most respected and successful playwrights. He's also the Artistic Director of the Lyceum Theatre in Edinburgh.

As quests go, it's slightly odd, sometimes light-hearted but serious in parts...
