Les processus démocratiques initiés au cours des années 1980 sur le continent africain s’étiolent désormais sur l’autel de la mal-gouvernance, du népotisme et de la corruption. Aussi suivant les contextes assiste-t-on au retour de coups d’État, ou à des versions plus modernes que sont les coups d’État constitutionnels. Frustrations et rancœurs cumulées des « damnés de la Terre » trouvent dans le terrorisme un contre-discours, un statut, témoins de la déterritorialisation des États dans l’i...

The prairie of Bureau Co., Illinois in the 1840s could hardly be thought of as the location for a planned utopian settlement. This is especially true if the motivation for the effort was the complex and controversial writings of a French utopian socialist who never stepped foot on American soil, much less the prairies of northern Illinois. The elaborate doctrines of Charles Fournier would be imported and stimulate thousands of Americans to action – specifically some idealists residing in B...

James Weldon Johnson (1871–1938) exemplified the ideal of the American public intellectual as a writer, educator, songwriter, diplomat, key figure of the Harlem Renaissance, and first African American executive of the NAACP. Originally published anonymously in 1912, Johnson’s novel The Autobiography of an Ex-Colored Man is considered one of the foundational works of twentieth-century African American literature, and its themes and forms have been taken up by other writers, from Ra...

Trichoderma spp. are biotechnologically significant fungi, being widely used both in agriculture and industry. These microbes are also a potential drug source of clinical importance. In recent years, driven by advances in genetics and genomics, research on these fungi have opened new avenues for its varied applications. Divided into three sections, covering taxonomy and physiology, interactions with plants and applications and significance, this book also discusses topics that have seen ra...

L’Afrique est devenue un continent d’avenir, entend-on ici ou là. Elle affiche un appétit sans limite pour les téléphones portables et les nouveaux riches ont adopté tous les tics des classes moyennes mondialisées. De « pré carré » de l’ancienne Europe coloniale, l'Afrique devrait devenir en 2030 membre à part entière de la nouvelle triade (Chine-Inde-Afrique) en lieu et place des États-Unis-Europe-Japon. Les pays émergents – dont la Chine – y trouvent les potentialités naturelles rares et...

This volume is a study of the career of Robert Lansing, Woodrow Wilsons Secretary of State from 1915 to 1920. Holding this office during the neutrality period, Americas entry into World War I, and the peace negotiations that followed, his was an important position at a critical juncture in American history. While many historians have dismissed Lansings contributions as insubstantial, this author believes otherwise. This work will show that in nudging a reluctant president toward war with G...

The contributors to this volume address reasoning and problem solving as fundamental to learning and teaching and to modern literacy.

The longstanding pedagogical assumption that the attainment of useful knowledge proceeds from lower level learning based on the practice of fundamental sk...

First published in 1983. The essays in this book are based on papers presented at a symposium held in March 1976 at the Learning and Development Center (LRDC), University of Pittsburgh. It was planned to serve three purposes: to pay tribute to retiring chairman Ralph W. Tyler, to mark the dedication of LRDC's new buiding and to provide an opportunity for those involved in research and development to reflect further on its implications for school change.
