This work comprises a collection of the writings of Ruqaiya Hasan, an influential figure in the systemic functional linguistic learning school. It discusses the relation between text and context and the realization of context in language; the 'network', which is outlined as analytic tool which can be applied at two strata of language, the lexico-grammatical and the semantic; as well as aspects of the social structure that are implicated in the way cultures and subcultures express themselves.

The Flowering of Australia's Rainforests provides a comprehensive introduction to the pollination ecology, evolution and conservation of Australian rainforest plants, with particular emphasis on subtropical rainforests and their associated pollinators. This significantly expanded second edition includes new information on the impact of climate change, fire, fragmentation and invasive species. Rainforests continue to be a focus of global conservation concern, not only from threats to biodiversity in general, but to pollinators specifically. Within Australia, this has been emphasised by recent cataclysmic fire impacts, ongoing extreme drought events, and the wider consideration of climate change. This second edition strengthens coverage of these issues beyond that of the first edition. The Flowering of Australia's Rainforests makes timely contributions to our understanding of the nature and function of the world's pollinator fauna, plant-reproduction dependencies, and the evolutionary pathway that has brought them to their current state and function. Illustrated with 150 colour plates of major species and rainforest formations, this reference work will be of value to ecologists and field naturalists, botanists, conservation biologists, ecosystemmanagers and community groups involved in habitat restoration. FEATURES: Provides an overview of the pollination ecology of Australia's rainforests in a world rainforest context. In particular discusses the pollination ecology of threatened subtropical rainforests, including the impact of climate change, fragmentation, fire and invasive species. Provides an introductory review of plant evolution and plant-pollinator relationships. Discusses pollination syndromes and the role and function of pollinator groups. Serves as a companion volume to The Invertebrate World of Australia's Subtropical Rainforests

Among the runners of C. C. Pyle's First Annual International Transcontinental Foot Race were an assortment of underdogs, including twenty-year-old Oklahoman and part Cherokee Andy Payne, who wanted to win over the girl of his dreams and pay off the mortgage on his family's farm; Paul "Hardrock" Simpson, who was in over his head but couldn't let down his North Carolina hometown; Mike Kelly, a luckless boxer from Indiana; Seattle's Ed Gardner, one of four black runners who encountered bigotry; Charles Hart, a sixty-three-year-old Englishman hoping his best days weren't behind him; and Frank Johnson, a middle-aged husband, father, and steelworker from St. Louis who broke away from his humdrum life and dared to do something different. Newspaper and magazine journalist Geoff Williams details this historic event and the colorful cast of characters involved, based on firsthand accounts of those who were there and interviews from many living descendants. C. C. Pyle's Amazing Foot Race is a classic American story so astonishing and surreal that you have to hear it to believe it.

This book presents a unique range of interdisciplinary work on questions of language development and evolution. It makes visible the significant contribution which meaning-oriented linguistics is making to debates about the origins of language - from the perspective of language evolution in the species (viewed as the evolution of "meaning potential") to language development in the child (viewed as "learning how to mean"). As well as linguistics in the systemic functional, or Hallidayan, tradition, the book offers contributions from primatology, psychiatry, sociology and education. What the authors share is a view of language as a social semiotic system. By seeing language in this way, and drawing on actual language corpora, the authors are able to address major questions of deep social significance, including: the role of grammar in the emergence of consciousness, from protolanguage to higher order consciousness the dynamics of language variation, including semantic variation, in children's development children's learning in and about a second language the significance of different ways of talking about language for school literacy development understanding borderline personality disorder from the perspective of language development.
