The first study comparing the long-term effectiveness of voluntary desegregation plans with magnet programs to mandatory reassignment plans.

Massachusetts is one of only nine states in the country to require bilingual education in all school districts where there is a sufficient number of limited-English-proficient (LEP) students. Moreover, Massachusetts has set the lowest threshold for mandatory bilingual education in the country. Observations of actual classroom practice demonstrates that these students are not all receiving the same style of education. Generally, only Spanish-speaking students are taught to read & write in their native language, while also receiving some native language instruction in other academic subjects, as existing law requires. Students from virtually all other groups, though enrolled in "bilingual education," receive instruction almost exclusively in English, with at most a few hours per week of enrichment in their native languages & cultures. Twenty-five years after passage of the bilingual education law in Massachusetts, there is still no proof that the mandated approach to teaching works better than other approaches, such as intensive English instruction. Not only is there no proof from Massachusetts, but there is none from the many studies that have been conducted in other states. If one can draw any conclusion, it is that teaching a LEP student in their native language is at least marginally detrimental to their acquisition of English.

"La période du post-partum est cruciale pour la mère, l'enfant et le couple parental. Leur santé physique, psychologique et sociale peut être contrariée, voire menacée. Ce "Guide du post-partum" est le fruit d'un travail conjoint de gynécologues-obstétriciens, de pédiatres et de sages-femmes issus du GGOLFB et/ou de l'ONE. Ils se sont adjoint le concours d'experts d'autres spécialités ou de différentes disciplines engagés dans le suivi de la naissance. Cet ouvrage a été rédigé à l'attention de tous les prestataires de soins impliqués dans le post-partum. Il a été conçu comme un outil de référence quotidien, utilisable par tous ces professionnels appartenant à un pays francophone : Belgique, France, Suisse, Canade et Afrique, en accord avec les derniers développements scientifiques."--Page 4 de la couverture.

Annotation Now in a thoroughly-updated and expanded second edition, Wiley Encyclopedia of Food Science and Technology covers fundamental concepts and practical requirements in food science, as well as cutting-edge technological and industry information. The encyclopedia features A-to-Z coverage of all aspects of food science, including: the properties, analysis, and processing of foods; genetic engineering of new food products; and nutrition. In addition, nontechnical information is included, such as descriptions of selected scientific institutions, and research and development in government agencies. Like the first edition, this Second Edition will become the standard reference for food scientists, bioengineers, and biotechnologists. From reviews of the first edition: " ... fills a definite need in the food science and technology literature ... I have little doubt that this encyclopedia will become one of the classic works in this ever-growing subject."--Food and Chemistry
