They claimed the abuse itself had turned them into criminals.Debby Jones, whose husband's attacker was jailed for life for murder, said: "He had gone to Milford Haven to refuel the boat and take the crew out for a Christmas drink. Last year the three-year-old son of a murdered woman was twice turned down for criminal compensation over her death because of her background as a prostitute.And a number of victims of child abuse at children's homes also challenged CICB rulings that the compensation they were entitled to would be reduced because they had subsequently acquired criminal convictions. Debby Jones, whose 36-year-old husband, Philip, would have received around pounds 5,000 if his attacker had only broken his leg, has been told she can have only pounds 1,100 funeral expenses and no compensation for herself or her sons, both aged under 10. Because she decided to try and run her husband's fishing boat after his death, the Criminal Injuries Compensation Board has ruled that she has not suffered any hardship and cannot therefore have any money.Lawyers attacked the decision and are appealing for compensation for Mrs Jones and her sons, who live in Milford Haven in west Wales.The appeal is the latest of a number of challenges to controversial decisions by the CICB. A mother of two young children whose husband was kicked to death in the street by a stranger has been told she can have no criminal injuries compensation because she kept his fishing boat.

"It sounds like a conspiracy to keep the North Pole for men," she said. Whatever the truth of the theory, it appears polar bears are far too sensible to venture as far north as Penguin Echo will go.As a member of Echo, Ms Hamilton shares the pressure of being in the final team. "The others who have gone before have done such an amazing job that we are all terrified of letting them down," she said.

"We made it a relay so that ordinary women who couldn't afford to take months off work could take part," she explained.She is mystified by the idea that women do not take to the Arctic because polar bears smell them more easily they do male explorers and might attack them. "Because the geographical North Pole moves all the time it will be a very private experience, a different Pole from anyone else's."A keen explorer of far-flung terrain, the 33-year-old film financier's dream grew from a fascination with deserts into a desire to achieve something no one else had. Still others use adjoining chambers or a honeycomb effect so that shocks can be distributed along the shoe. Midsoles are often made with air capsules, or gel using "energy return" chambers designed to cushion the shock generated when your foot hits the ground - which may otherwise travel up to your knees or lower back, with potentially painful results.Some manufacturers use a shock-absorbent, spongy material in the midsole Others use a hi-tech foam.
