The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."

Abstract: The authors investigate the occupational placement of immigrants in the U.S. labor market using census data. They find striking differences among highly educated immigrants from different countries, even after they control for individuals' age, experience, and level of education. With some exceptions, educated immigrants from Latin American and Eastern European countries are more likely to end up in unskilled jobs than immigrants from Asia and industrial countries. A large part of the variation can be explained by attributes of the country of origin that influence the quality of human capital, such as expenditure on tertiary education and the use of English as a medium of instruction. Performance is adversely affected by military conflict at home which may weaken institutions that create human capital and lower the threshold quality of immigrants. The selection effects of U.S. immigration policy also play an important role in explaining cross-country variation. The observed under-placement of educated migrants might be alleviated if home and host countries cooperate by sharing information on labor market conditions and work toward the recognition of qualifications.

International migration, the movement of people across international boundaries, has enormous economic, social and cultural implications in both origin and destination countries. Using original research, this title examines the determinants of migration, the impact of remittances and migration on poverty, welfare, and investment decisions, and the consequences of brain drain, brain gain, and brain waste.

"Based on static partial equilibrium analysis, the "new brain drain" literature argues that, by raising the return to education, a brain drain generates a brain gain that is, under certain conditions, larger than the brain drain itself, and that such a net brain gain results in an increase in welfare and growth due to education's positive externalities. This paper argues that these claims are exaggerated. In the static case, and based on both partial and general equilibrium considerations, the paper shows that (1) the size of the brain gain is smaller than suggested in that literature; (2) the impact on welfare and growth is smaller as well (for any brain gain size); (3) a positive brain gain is likely to result in a smaller, possibly negative human capital gain; (4) an increase in the stock of human capital may have a negative impact on welfare and growth; and (5) in a dynamic framework, the paper shows that the steady-state brain gain is equal to the brain drain so that a "beneficial brain drain" cannot take place, and a net brain loss is likely during the transition.

Incineration has been used widely for waste disposal, including household, hazardous, and medical wasteâ€"but there is increasing public concern over the benefits of combusting the waste versus the health risk from pollutants emitted during combustion. Waste Incineration and Public Health informs the emerging debate with the most up-to-date information available on incineration, pollution, and human healthâ€"along with expert conclusions and recommendations for further research and improvement of such areas as risk communication. The committee provides details on: Processes involved in incineration and how contaminants are released. Environmental dynamics of contaminants and routes of human exposure. Tools and approaches for assessing possible human health effects. Scientific concerns pertinent to future regulatory actions. The book also examines some of the social, psychological, and economic factors that affect the communities where incineration takes place and addresses the problem of uncertainty and variation in predicting the health effects of incineration processes.
