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.

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.

Washed Away

Tillfälligt slut
The incredible story of a flood of near-biblical proportions-its destruction, its heroes and victims, and how it shaped America's natural-disaster policies for the next century.The storm began March 23, 1913, with a series of tornadoes that killed 150 people and injured 400. Then the freezing rains started and the flooding began. It continued for days. Some people drowned in their attics, others on the roads when the tried to flee. It was the nation's most widespread flood ever—more than 700 people died, hundreds of thousands of homes and buildings were destroyed, and millions were left homeless. The destruction extended far beyond the Ohio valley to Illinois, Indiana, Michigan, Nebraska, Pennsylvania, Tennessee, Arkansas, Louisiana, Kentucky, West Virginia, New York, New Jersey, and Vermont. Fourteen states in all, and every major and minor river east of the Mississippi. In the aftermath, flaws in America's natural disaster response system were exposed, echoing today's outrage over Katrina. People demanded change. Laws were passed, and dams were built. Teams of experts vowed to develop flood control techniques for the region and stop flooding for good. So far those efforts have succeeded. It is estimated that in the Miami Valley alone, nearly 2,000 floods have been prevented, and the same methods have been used as a model for flood control nationwide and around the world.

Summer of Death

A riveting historic narrative that tells the iconic story of the great heat wave that ravaged the continent in the last gasps of the Dust Bowl.In 1936, after one of the coldest winters on record, North America experienced a heat wave that remains unmatched today. Thanks to a combination of an unusually warm sea surface in the Atlantic and Pacific, stagnating high-pressure, drought, and poor farming techniques, temperatures soared across virtually every state (and the territory of Alaska) for months. This summer, the sun aimed its deadly rays at more than 11,000 Americans and 1,000 Canadians. Air conditioning was uncommon, workers’ rights were few, and in an age before high blood pressure medication, a lot of middle-aged adults, toiling in the sun, were literally working themselves to death. This was a summer in which there was almost no escape from the 100-plus temperatures, and woe to those who tried. Men, women, and children rushed into rivers to cool off, only to drown. Desperate people slept on roofs to catch a breeze, only to roll over and plummet to their deaths. Young and old, rich and poor, human and animal, it didn’t really matter. If the heat wanted you, it was going to get you. The heat wave of 1936 sparked massive social changes and technological advances, as well as improvements in health care, and it ignited an ongoing impassioned national dialogue about climate change that continues, to varying degrees, to this day. Filled with vivid detail and characters as intense as the oppressive heat itself, The Summer of Death is the definitive narrative history about this paradigm changing season. In the tradition of Timothy Egan’s The Worst Hard Time and Edward P. Kohn’s Hot Time in the Old Town, The Summer of Death reveals a unique and vital chapter of American history, one that could portend dire consequences for our future.
