Las aportaciones de Lynn Margulis a la biología son de una importancia incuestionable. Sus ideas acerca del papel de la simbiosis en el origen de las células nucleadas han sido demostradas casi en su totalidad. Por eso se puede decir que Margulis ha removido las de por sí ya agitadas aguas de las explicaciones científicas del origen y evolución de la vida. Además, ha colaborado con numerosos científicos e intelectuales en otros ámbitos del conocimiento: así, por ejemplo, con James Lovelock contribuyó al desarrollo de la hipótesis Gaia y con Dorion Sagan ha publicado numerosos libros y artículos de divulgación científica y reflexión filosófica sobre la evolución biológica y el funcionamiento de un planeta vivo.

The book interprets the Cuban revolutionary movement from 1868 to 1959 as a continuous process that sought political independence and social and economic transformation of colonial and neocolonial structures. Cuba is a symbol of hope for the Third World. The Cuban Revolution took power from a national elite subordinate to foreign capital, and placed it in the hands of the people; and it subsequently developed alternative structures of popular democracy that have functioned to keep delegates of the people in power. While Cuba has persisted, the peoples of the Third World, knocked down by the neoliberal project, have found social movement and political life, a renewal that is especially evident in Latin America and the Non-Aligned Movement. At the same time, the capitalist world-economy increasingly reveals its unsustainability, and the global elite demonstrate its incapacity to respond to a multifaceted and sustained global crisis. These dynamics establish conditions for popular democratic socialist revolutions in the North.

Contributors: Luigi Burzio, Héctor Campos, Noam Chomsky, Joseph E. Emonds, Robert Freidin, James Harris, Ray Jackendoff, Paula Kempchinsky, Howard Lasnik, Claudia Parodi, Carlos Piera, A.

This book explores the historical and cultural significance of comics in languages other than English, examining the geographic and linguistic spheres which these comics inhabit and their contributions to comic studies and academia. The volume brings together texts across a wide range of genres, styles, and geographic locations, including the Netherlands, Colombia, Greece, Mexico, Poland, Finland, Portugal, Ireland, and the Czech Republic, among others. These works have remained out of reach for speakers of languages other than the original and do not receive the scholarly attention they deserve due to their lack of English translations. This book highlights the richness and diversity these works add to the corpus of comic art and comic studies that Anglophone comics scholars can access to broaden the collective perspective of the field and forge links across regions, genres, and comic traditions. Part of the Global Perspectives in Comics Studies series, this volume spans continents and languages. It will be of interest to researchers and students of comics studies, literature, cultural studies, popular culture, art and design, illustration, history, film studies, and sociology.

Les espècies evolucionen, canvien amb el pas del temps i així ho va constatar i argumentar Charles Darwin. El que té entre les mans és una obra que intenta integrar dues grans visions de l?evolució que sovint es presenten enfrontades. D?una banda, la visió que emfatitza la contingència, els accidents congelats i la irreversibilitat, i determina una ciència eminentment històrica. De l?altra, la visió més racio¬nal, basada en la comprensió dels processos d?auto¬organització semblants als d?altres sistemes físics allunyats de l?equilibri termodinàmic, i que determina una ciència estructuralista. El resultat és una visió més rica i plural del fenomen evolutiu, en la qual es posen en evidència els paradigmes clàssics. Una revisió acurada de la visió més ortodoxa de l?evolució a la recerca d?explicacions teòriques que van més enllà dels límits de la biologia.

Ernesto Cardenal and Sergio Ramírez are two of the most influential Latin American intellectuals of the late twentieth and early twenty-first centuries. Addressing Nicaragua's struggle for self-definition from divergent ethnic, religious, generational, political, and class backgrounds, they constructed distinct yet compatible visions of national history, anchored in a reappraisal of the early twentieth-century insurgent leader Augusto César Sandino. During the Sandinista Revolution of 1979-90, Cardenal, appointed Nicaragua's minister of culture, became one of the most provocative and internationally recognized figures of liberation theology, while Ramírez, a member of the revolutionary junta, and later elected vice-president of Nicaragua, emerged as an authoritative figure for third world nationalism. But before all else, the two were groundbreaking creative writers. Through a close reading of the works by Nicaragua's best-known and most prolific modern authors, Sandino's Nation studies the construction of Nicaraguan national identity during three distinct periods of the country’s recent history - before, during, and after the 1979-90 revolution. Stephen Henighan offers rigorous textual analyses of poems, memoirs, essays, and novels, interwoven with a sharply narrated history of Nicaragua. The only comprehensive study of the careers of Cardenal and Ramírez, Sandino's Nation is essential to understanding transformations to both Nicaragua and the role of the writer in Latin America.
