This book introduces a framework for examining bilingual identity and presents the cases of seven individual children from a study of young students' bilingual identities in an Australian primary school. The new Bilingual Identity Negotiation Framework brings together three elements that influence bilingual identity development - sociocultural connection, investment and interaction. The cases comprise individual stories about seven young, bilingual students and are complemented by some more general investigations of bilingual identity from a whole class of students at the school. The framework is explained and supported using the students' stories and offers readers a new concept for examining and thinking about bilingual identity. This book builds upon past and current theories of identity and bilingualism and expands on these to identify three interlinking elements within bilingual identity. The book highlights the need for greater dialogue between different sectors of research and education relating to languages and bilingualism. It adds to the increasing call for collaborative work from the different fields interested in language learning and teaching such as TESOL, bilingualism, and language education. Through the development of the framework and the students' stories in this study, this book shows how multilingual children in one school in Australia developed their identities in association with their home and school languages. This provides readers with a model for examining bilingual identity in their own contexts, or a theoretical construct to consider in their thinking on bilingualism, language and identity.
Here in one source is a wide variety of practical, everyday information often required by chemists but seldom found together, if at all, in the standard handbooks, data collections, manuals, and other usual sources. Discussing physical, chemical, and mechanical properties of substances and systems, the authors answer such questions as:<ul> <LI>How do I test for and destroy peroxides in different solvents and what is the best way to purify such solvents? <LI>What are the structure, physical properties, and recent references to the use of common-name solvents and solvent aids such as the "Skellysolves," "Cellosolves," "Crownanes," and "Glymes"? <LI>What is the utility of a particular molecular sieve, or permeation gel, or epoxy cement, or liquid crystal, and where do I buy them and find references to their application? </ul> The book is divided into nine chapters and covers properties of atoms and molecules, spectroscopy, photochemistry, chromatography, kinetics and thermodynamics, various experimental techniques, and mathematical and numerical information, including the definitions, values, and usage rules of the newly adopted International System of Units (SI Units). A section on statistical treatment of data which provides an actual least-squares computer program is also included. In the spectroscopy chapter, very extensive and up-to-date collections of spectral correlation data are presented for ir, uv-vis, optical rotation, nmr, and mass spectra, along with data on esr and nqr spectroscopy. Also included is a variety of hard-to-classify but frequently sought information, such as names and addresses of microanalysis companies and chemistry publishers, descriptions and commercial sources of atomic and molecular models, and safety data for hazardous chemicals. More than 500 key references are also included, most of which are recent. There are important hints and definitions associated with the art as well as the state of the art for the appropriate subjects. Also found throughout the book are about 250 suppliers and directions for obtaining special booklets or other material. <p> Containing a wealth of useful information, <I>The Chemist's Companion</I> will be an indispensable guide for students and professional chemists in nearly all the chemical disciplines. In addition, it will provide for the teacher and student an unusual adjunct for use in a broad cross-section of chemistry courses.
