It is widely acknowledged that we have a duty to protect the environment. Yet, current environmental policy discussions demonstrate that fulfilling this in practice is a difficult, complex, and costly task. There are many ethical questions arising from such discussions. Should we care about the environment because it is economically valuable or because nature has intrinsic value? How do we establish an ethical trade-off between our current needs and those of future generations? Should we protect individual species or entire ecosystems instead? What way should we discuss societal values and ideals, or should scientific analysis take precedence within decision making practice? This book aims to tackle some of these thorny sustainability issues and responds to them with a cohesive, original alternative in the form of the precautionary ecosystem health principle (PEHP). It provides a detailed philosophical approach and advocates that a PEHP approach is able to overcome many of these stark and challenging difficulties within sustainability theory and environmental policy.

Mark Ryan's brilliant reinvention of Robert Louis Stephenson's Strange Case of Dr Jekyll and Mr Hyde. Carl Jung introduces the audience to an inmate of Broadmoor Asylum, known only as Mr Hyde. Through a series of interviews, Jung attempts to understand the man through his analysis of the divided self. However, as the regular meetings progress, the true horror of the story unfolds as Hyde begins to gain the upper hand.

What would you do if you were struck by an enemy bullet in wartime, then realised you were still alive? For most of us, that would be the end of our fight. If we were capable of thought while we tried to cope with the pain, we’d probably hope to be rushed to hospital so that someone could save our lives. But a hundred years ago, in the opening battle of the First World War at Mons, two young men didn’t react like that. Lieutenant Maurice Dease and Private Sidney Godley, born only weeks apart into sharply contrasting worlds, shared the same defiance and steely streak. Without a thought for themselves, they went back into the action for more, sustaining dreadful wounds in the process. One man died, the other lived – pieced back together painstakingly by the Germans, who had taken many casualties of their own while overrunning the British position. Together, and against the odds, Dease and Godley became the first winners of the Victoria Cross in the First World War. Here Mark Ryan uses contemporary documentation and images to tell their astounding, fascinating stories, putting the focus on two genuine and ordinary heroes of the Great War.

Maurice ‘Moggy’ Mayne was a cricket-loving air gunner in the Second World War, with a pretty girlfriend back home in rural England. His turret was in a Bristol Beaufort and his pilot had to fly with almost suicidal bravery at giant German warships before releasing the torpedo. No wonder Moggy’s first pilot cracked up and his second liked to drink. When he was shot down, Moggy miraculously survived – unlike his best friend Stan. Moggy was sent to Stalag Luft VIIIB, an infamous German POW camp near the Polish border, where he was badly treated. Fearing losing his beloved girlfriend Sylvia forever, and risking recapture and execution, he saw the chance to escape alone, thus beginning an epic journey through Nazi-occupied Germany. As the Gestapo shot other escaped British servicemen, Moggy Mayne came agonisingly close to lasting freedom. Instead, as the war neared its end, he had to face the horrors of the ‘long march’ west – and he felt his life slipping away. Would he ever see his Sylvia again?

Years ago, Seán 'Tyrone' O'Brien left his wife and son in County Tyrone to find work in the South Wales Valleys. Now his wife is dying, and sends her son Jack out to find out what became of his father. Séan's last letter came from 'somewhere called Aberuffern'. Unbeknownst to Jack, Aber-uffern translates as 'the mouth of Hell', and a young man's journey in innocence is quickly enveloped in nightmare.Inspired by the Mexican novel Pedro Paramo by Juan Rulfo, this haunting novella is based on a play of the same name, premiered in Cardiff in 2010. The lively, blackly humorous and intelligent storytelling is accompanied by a series of 20 woodcuts by the author.Mark Ryan played in various punk bands during the late 1970s, including Adam and the Ants. He later turned to theatre and began a successful career as a playwright. He is the author of The Strange Case Of Dr Jekyll And Mr Hyde As Told To Carl Jung By An Inmate Of Broadmoor Asylum, performed to five-star reviews in Edinburgh, London, Cardiff and San Francisco. Mark died in 2011, as he was finalising the text for this novel.

Based on the seasonal rhythms and festivals of the ancient year, this title draws its inspiration from pre-Celtic mythology and shamanic mysteries, placing mystical archetypes into a nature-based system rich in shamanic wisdom and forest lore.

Based on hundreds of hours of interviews with Sneum, Mark Ryan describes how Tommy made an incredible escape from Denmark in a battered old Hornet Moth aircraft - which he had to refuel in mid-air by climbing out on the wing. Later, he escaped from Denmark again - by walking across a treacherous frozen sea on which two of his companions died. Tommy brought over precious intelligence about the Nazi radar installations in Denmark and their atom bomb - his reward was to be imprisoned in Brixton as a suspected double agent and threatened with execution. He cheated the hangman - but it is only with the publication of this enthralling book that Sneum can be celebrated as, in the words of Professor R.V. Jones, Churchill's chief of scientific intelligence, 'one of the true heroes of World War II'.

Recent years have seen the development of powerful tools for verifying hardware and software systems, as companies worldwide realise the need for improved means of validating their products. There is increasing demand for training in basic methods in formal reasoning so that students can gain proficiency in logic-based verification methods. The second edition of this successful textbook addresses both those requirements, by continuing to provide a clear introduction to formal reasoning which is both relevant to the needs of modern computer science and rigorous enough for practical application. Improvements to the first edition have been made throughout, with extra and expanded sections on SAT solvers, existential/universal second-order logic, micro-models, programming by contract and total correctness. The coverage of model-checking has been substantially updated. Further exercises have been added. Internet support for the book includes worked solutions for all exercises for teachers, and model solutions to some exercises for students.

Everyday math skills can be painlessly learned and easily mastered, transforming readers from a person who doesn't know the meaning of APR into someone who understands credit card rates. Ryan's guide is broken into sections which review basic arithmetic from fractions to percents.
