What allows children to acquire language so effortlessly, with such speed, and with such amazing accuracy? Capitalizing on the most recent developments in linguistics and cognitive psychology, this volume sheds new light on the what, why, and how of the child's ability to acquire one or more languages.
The Handbook is one of a kind in a number of respects. It includes state-of-the-art treatments of acquisition from a variety of theoretical viewpoints ranging from functionalist approaches and the implications of the creolization of languages for the study of acquisition to the relevance of Chomsky's Minimalist Program. It contains overviews of the acquisition of all components of linguistic structure, treats the acquisition of the sign languages of the deaf, and discusses the specific problems of bilingual acquisition.
Key Features
*Addresses the following questions:
* Is the capacity for language acquisition constant throughout the career of the language learner (that is, is it "continuous") or does that capacity change in significant ways as the learner matures?
* Is the language capacity a separate module of the mind or does it follow from general, "all-purpose" cognitive capacities?
* What is innate in language acquisition and what is acquired on the basis of experience?
* What research/methodological issues arise in the study of child language acquisition?
* How might input from the language (or languages) of the environment, including visual/gestural input in the case of the sign languages of the deaf, affect the process and result of acquisition?
* How are the facts of non-normal acquisition to be explained?

This book is a much-expanded and updated edition of a previous volume, published in 1996 as No-tillage Seeding: Science and Practice. The base objective remains to describe, in lay terms, a range of international experiments designed to examine the causes of successes and failures in no-tillage. The book summarizes the advantages and disadvantages of no tillage and highlights the pros and cons of a range of features and options, without promoting any particular product. Topics added or covered in more detail in the second edition include:
DT soil carbon and how its retention or sequestration interacts with tillage and no-tillage
DT controlled traffic farming as an adjunct to no-tillage
DT comparison of the performance of generic no-tillage opener designs
DT the role of banding fertilizer in no-tillage
DT the economics of no-tillage
DT small-scale equipment used by poorer farmers
DT forage cropping by no-tillage
DT a method for risk assessment of different levels of machine sophistication
