Book Description
Les deux aspects essentiels de la memoire sont la formation de la trace et la retention du souvenir a long terme. Afin de comprendre ces processus, nous avons etudie leur mise en place au cours de l'ontogenese. Chez le raton, nous avons montre que: 1) ERK1/2 et la synthese de nouvelles proteines sont necessaires a la consolidation et reconsolidation des 3 jours postnatals; 2) les cinetiques de stabilisation de la memoire raccourcissent au cours du developpement post-natal; 3) une memoire precoce peut s'inverser avec l'age; 4) la capacite de retention a tres long terme apparait pendant une periode critique (une semaine avant le sevrage). Il semble donc que la memoire precoce implique des mecanismes moleculaires similaires a ceux observes chez l'adulte, mais sa dynamique evolue au cours du developpement post-natal."

Book Description
This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

Book Description
This book examines the promises as well as the challenges the demographic dividend brings to sub-Saharan Africa as fertility rates in the region fall and the labor force grows. It offers a detailed analysis of what conditions must be met in order for the region to take full economic advantage of ongoing population dynamics. As the book makes clear, the region will need to accelerate reforms to cope with its demographic transition, in particular the decline of fertility. The continent will need to foster human capital formation through renewed efforts in the areas of education, health and employment. This will entail a true vision and determination on the part of African leaders and their development partners. The book will help readers to gain solid knowledge of the demographic trends and provide insights into socioeconomic policies that eventually might lead sub-Saharan Africa into a successful future.

Book Description
Covering an area of over 130 million km2 spanning the Mediterranean, equator and tropics, the African continent features a spectacular geographic diversity. Consequently, it is characterised by extremely variable climatic, edaphic and ecological conditions, associated with a wide range of natural vegetation and wildlife, as well as human population density, crops and livestock. In this book, Henry Le Houérou presents his bioclimatic and biogeographic classification of Africa. The extensive data provide the basis for comparisons between various African regions, and with regions on other continents such as Latin America or the Indian subcontinent. The results constitute a rational basis for national, regional and sub-regional rural development planning, and for agricultural research dealing with aspects such as plant and animal introductions, the extrapolation or interpolation of experimental or developmental findings, and ecosystems dynamics. Possible problems of applications are also examined.

Book Description
This benchmark collection of cross-cultural essays on reproduction and childbirth extends and enriches the work of Brigitte Jordan, who helped generate and define the field of the anthropology of birth. The authors' focus on authoritative knowledge—the knowledge that counts, on the basis of which decisions are made and actions taken—highlights the vast differences between birthing systems that give authority of knowing to women and their communities and those that invest it in experts and machines. Childbirth and Authoritative Knowledge offers first-hand ethnographic research conducted by anthropologists in sixteen different societies and cultures and includes the interdisciplinary perspectives of a social psychologist, a sociologist, an epidemiologist, a staff member of the World Health Organization, and a community midwife. Exciting directions for further research as well as pressing needs for policy guidance emerge from these illuminating explorations of authoritative knowledge about birth. This book is certain to follow Jordan's Birth in Four Cultures as the definitive volume in a rapidly expanding field. This title is part of UC Press's Voices Revived program, which commemorates University of California Press's mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1999.
