Separation Logic is the twenty-first-century variant of Hoare Logic that permits verification of pointer-manipulating programs. This book covers practical and theoretical aspects of Separation Logic at a level accessible to beginning graduate students interested in software verification. On the practical side it offers an introduction to verification in Hoare and Separation logics, simple case studies for toy languages, and the Verifiable C program logic for the C programming language. On the theoretical side it presents separation algebras as models of separation logics; step-indexed models of higher-order logical features for higher-order programs; indirection theory for constructing step-indexed separation algebras; tree-shares as models for shared ownership; and the semantic construction (and soundness proof) of Verifiable C. In addition, the book covers several aspects of the CompCert verified C compiler, and its connection to foundationally verified software analysis tools. All constructions and proofs are made rigorous and accessible in the Coq developments of the open-source Verified Software Toolchain.

Nanyang is a South-East Asian saga melding romance, adventure, drama, and history. It is an epic story spanning a period of 200 years, during which corrupt colonialists and venal indigenous leaders vied with Chinese immigrants to exploit the region's natural resources with little regard for the suffering of the rural poor. It was a time that saw the main European powers extend their rivalry from their immediate environs to India, South-East Asia and China, where there were strategic and economic prizes to be won. A tale of love, tragedy, avarice and brutality, Nanyang - the Chinese name (Southern Ocean) for the region - begins in the mid seventeenth century, when Dutch soldiers and officials, sent by ship from Batavia to acquire laborers for the Java settlement, seize a young woman, Mei Ling, from a village in Fujian, China, along with scores of men. Seventeen-year-old Mei Ling is kidnapped at the behest of a lecherous Dutch official, who organizes a mutiny when the ship's captain places her under his protection. Nanyang follows the adventures of Mei Ling and her brother, who sets out to rescue her, and their descendants amid land and sea battles of warring nations, natural disasters and rampant disease. The protagonists are caught up in historical events (in Europe as well as South-East Asia), in which notable English, Dutch and Javanese figures play their real-life roles. The story begins in China and ends soon after the founding of Singapore by Sir Stamford Raffles, who features in the book along with other personalities of the period, including Horatio Nelson and Captain James Cook. Nanyang now comes with a comprehensive guide to the book's fictional characters and historical figures.

There was nothing unusual about that pleasant Wednesday morning. Henry and Martha Pickett, owners of a large rental house in Seattle had nothing planned. It was nine-thirty, Henry was out walking the dog, and Martha was sorting the day's mail; a utility bill, circulars read and disposed of, and then the letter. It was from Big Eye, Montana, home of Henry's twin brother, Homer. Martha was concerned; the twins are not letter writers, they keep in touch with infrequent phone calls and the annual Christmas card. The letter triggers a phone call, the phone call delivers a message that turns Henry Pickett's life upside down. His twin brother Homer has cancer.

HIV and Aids teaching is compulsory in British schools but the content is not prescribed. Should teaching in such a difficult field, where there are disputes among experts, be left to secondary school teachers with no specialist knowledge? And is it right that the subject should be compulsory? These awkward issues are confronted in this controversial paper which examines the materials being used by schools in HIV/Aids teaching and how teachers are approaching the subject. The authors conclude that, because of material provided by pressure groups, teachers are exaggerating the Aids problem and failing to stress the extent to which the risk of infection depends on behaviour. Rent-seeking by vested interests results in a serious distortion of the views presented to children. Their conclusion about Britain is that HIV/Aids teaching should no longer be compulsory. Either the law should be repealed or schools should simply drop the subject.
