Language in Action
presents a critical examination of four models of conversation: the Code model based on Chomsky’s linguistic views; the Speech Act model of Austin and Searle; the Inferential model of Grice and the Conversation Analytic model of Sacks and Schegloff. It also considers the Brown and Levinson model of politeness in conversation. Using many examples from natural talk and drawing on the positive aspects of the reviewed models, Turnbull proposes a new Social Pragmatic model of conversation as social interaction.

Biology is often viewed today as a bipartisan field, with molecular level genetics guiding us into the future and natural history (including ecology, evolution, and conservation biology,) chaining us to a descriptive scientific past. In Darwinian Detectives, Norman Johnson bridges this divide, revealing how the tried and true tools of natural history make sense of the newest genomic discoveries. Molecular scientists exploring newly sequenced genomes have stumbled upon quite a few surprises, including that only one to ten percent of the genetic material of animals actually codes for genes. What does the remaining 90-99% of the genome do? Why do some organisms have a much lower genome size than their close relatives? What were the genetic changes that were associated with us becoming human? As molecular biologists uncover these and other new mysteries, evolutionary geneticists are searching for answers to such questions. Norman Johnson captures the excitement of the hunt for our own genetic history. Through lively anecdotes, he explores how researchers detect natural selection acting on genes and what this genetic information tells us about human origins.

Passionate Darwinian David Attenborough, who sees evolution as the cornerstone of all the series he has ever made, shares his personal view on Darwin's controversial idea. Journeying through the last two hundred years, he tracks the changes in our understanding of the natural world, and asks three key questions: How and why did Darwin come up with his theory? Why do most people think he was right? Why is it more important now than ever before?

The Encyclopedia of Ancient Natural Scientists is the first comprehensive English language work to provide a survey of all ancient natural science, from its beginnings through the end of Late Antiquity. A team of over 100 of the world’s experts in the field have compiled this Encyclopedia, including entries which are not mentioned in any other reference work – resulting in a unique and hugely ambitious resource which will prove indispensable for anyone seeking the details of the history of ancient science.

Young David Morgan, gifted heir apparent to a South African fortune, rebels against the boardroom future mapped out for him with sickening predictability by his family. Drawn to the sky as though to his natural element, he trains to become a brilliant jet pilot and, fleeing from his home and all it stands for, sets out to make his own life.
