How do young black students respond, resist, and work to transform their school experience? How do young people adapt, survive, and then succeed in spite of their negative school experience? For an increasing number of marginalized black youth, the paths to social success can actually lie outside school walls. Black Youth Matters presents a compelling, empirical picture of black youth who creatively respond to permanent school exclusion. Structural approaches to social stratification often set the terms of discussion around isolated narratives of individual "success stories." In this book, the authors intervene with a new point of view by focusing instead on collectives of broader black communities. They both engage with and move beyond structural models of stratification and education, thereby affirming the enduring importance of individual and collective aspiration—an impulse that has not been exhausted for black youth even in the face of systematic, longstanding, and overwhelming inequality. Based on long-term ethnographic research with young people permanently excluded from school, Black Youth Matters examines the resourcefulness of young black people in overcoming the process of school failure to forge more positive futures for themselves. This book should be of interest to sociologists, educators, anthropologists, policy-makers, as well as community activists.
In the Survey of Recent Historical Works, which according to custom concludes this IXth volume of the Acta, is a notice of the recent 'Report of the Dutch research, with suggestions for future development'. Such a report could easily be classified as an attempt to bring pressure to bear on financial resources for support of a somewhat neglected branch of scientific effort, indeed as a symptom of the current disease of notatitis. A recent special issue 'Regeren door notas', of the periodical Beleid and Maatschappij, March-April 1976, discusses this severe Dutch epidemic of official note-writing, for any purpose, on any matter, at any time, by any sort of official committee to any sort of official body. But even if such were the only reason for the production of this Report, which indeed it is not, the Report will stand on its own feet, as significant and of consequence. In general, however, this Report makes sad reading. It would seem that Dutch historical research and historiography lags far behind comparable foreign developments. There are said to be immense gaps in knowledge of and insight into virtually all fields of the Dutch past and moreover a total lack of modem sophistication. Inevitably, currently fashionable techniques such as programming, co-ordination, and teamwork are suggested as desirable, and a preference is expressed for the currently highly regarded socio-historical approach.
The combination of color schlieren with high speed flash techniques has proved to be a valuable tool for investigating high speed transient events. Fully two dimensional refractive index information can be ob tained. The resolution on 35 mm film was sharp enough to allow 50 cm by 75 cm color enlargements. REFERENCES 1.

I notice that in two of his pic tures density gradients in directions at right angles are shown by the same colour transitions. MY' J Kim Vandiver: The photographs presented were not composed to yield accurate determination of the direction of density gradients.
A comprehensive guide to the content and consequences of drugs, micronutrients, radiopharmaceuticals and environmental and occupational chemicals in human milk
A comprehensive guide to the content and consequences of drugs, micronutrients, radiopharmaceuticals and environmental and occupational chemicals in human milk
Now in its second edition, Drugs and Human Lactation is a comprehensive guide to the content and consequences of xenobiotics and micronutrients in human milk, and remains by far the most thorough and extensive work available on this subject. The excellent methodology used for the compilation of the 1st edition has been retained.It begins with an outline of the processes by which substances enter milk during its formation, the effects of drugs on the milk production process, the main determinants of drug excretion into milk and their disposition in the child. There follows an analysis of current data on 234 individual drugs, describing the extent of their passage into human milk, and assessing the risk to the suckling infant. Vitamins and essential trace elements, and radiopharmaceuticals are similarly reviewed. Also included is an account of the factors that influence the passage of environmental and occupational chemicals into milk. The result is a complete overview of what is known and proven, with clear pointers to matters which require further study, and brings the various subject areas up to date. Risks, uncertainties and false alarms which exist have been defined in such a way that they can be avoided.Once again, Drugs and Human Lactation provides a comprehensive guide to the content and consequences of substances in milk. The volume will provide a rational basis for making therapeutic decisions in women who seek to breast-feed.Reproductive Immunology on the first edition: ...a superbly written compendium of reliable information and sensible conclusions and recommendations.
This study is an important new account of the life and work of the flemish master Petrus Christus. It is the first volume to focus specifically on the physical characteristics of his works as criteria for judging attribution, dating, and the extent to which he was indebted to Jan Van Eyck and other artists for the development of his technique and style.
