Lamarck y los mensajeros by Máximo Sandín Pdf

En los últimos años se están produciendo descubrimientos espectaculares en el campo de la Genética y de la Biología Molecular que están poniendo en cuestión muchos de los fundamentos de la Teoría Evolutiva convencional. En este ensayo -breve, pero rico en ideas- se sintetizan y se relacionan los últimos hallazgos en distintos campos de la Biología integrándolos en un contexto evolutivo como concepto unificador. En este sentido, los más recientes datos sobre los mecanismos víricos de transferencia de información genética y los descubrimientos de secuencias de origen viral en los genomas animales y vegetales apuntan al hecho sorprendente de que los virus han podido jugar un importante papel en la Evolución como fuente de variación genética. Al mismo tiempo, el profesor Sandín hace una llamada a la reflexión, en la convicción de que sólo desde el pensamiento sosegado, apartado de la feroz competencia que domina el ámbito científico, puede retomarse la idea de un saber científico verdaderamente al servicio de la Humanidad.

Death in the City by Kathryn A. Sloan Pdf

At the turn of the twentieth century, many observers considered suicide to be a worldwide social problem that had reached epidemic proportions. In Mexico City, violent deaths in public spaces were commonplace in a city undergoing rapid modernization. Crime rates mounted, corpses piled up in the morgue, and the media reported on sensational cases of murder and suicide. More troublesome still, a compelling death wish appeared to grip women and youth. Drawing on a range of sources from judicial records to the popular press, Death in the City investigates the cultural meanings of self-destruction in modern Mexico. The author examines responses to suicide and death and disproves the long-held belief that Mexicans possess a cavalier attitude toward suffering.

The Great American Biotic Interchange by Alberto Luis Cione,Germán Mariano Gasparini,Esteban Soibelzon,Leopoldo Héctor Soibelzon,Eduardo Pedro Tonni Pdf

South American ecosystems suffered one of the greatest biogeographical events, after the establishment of the Panamian land bridge, called the “Great American Biotic Interchange” (GABI). This refers to the exchange, in several phases, of land mammals between the Americas; this event started during the late Miocene with the appearance of the Holartic Procyonidae (Huayquerian Age) in South America and continues today. The major phases of mammalian dispersal occurred from the Latest Pliocene (Marplatan Age) to the Late Pleistocene (Lujanian Age). The most important and richest localities of Late Miocene-Holocene fossil vertebrates of South America are those of the Pampean region of Argentina. There are also several Late Miocene and Pliocene localities in western Argentina and Bolivia. Other important fossils have been collected in localities of Pleistocene age outside Argentina: Tarija (Bolivia), karstic caves of Lagoa Santa and the recently explored caves of Tocantins (Brasil), Talara (Perú), La Carolina (Ecuador), Muaco (Venezuela), and Cueva del Milodon (Chile), among others. The book discusses basic information for interpreting the GABI such as taxonomic composition (incorporating the latest revisions) at classical and new localities for each stage addressing climate, environments, and time boundaries for each stage. It includes the chronology and dynamics of the GABI, the integration of South American mammalian faunas through time, the Quaternary mammalian extinctions and the composition of recent mammalian fauna of the continent.

Utopias in Latin America by Juan Pro Pdf

Latin America has historically been a fertile ground where utopian projects, movements, and experiments could take root and thrive. Each of the thirteen authors in this collective volume address a particular case or specific aspect of Latin American utopianism from colonial times to the present day. The America that the Spanish and Portuguese discovered became, from the sixteenth century onwards, a space in which it was possible to imagine the widest variety of forms of human coexistence. Utopias in Latin America reconsiders the sense and understanding of utopias in various historical frames: the discovery of indigenous cultures and their natural environments; the foundation of new towns and cities in a vast colonial territory; the experimental communities of nineteenth-century utopian socialists and European exiled intellectuals; and the innovative formulae that attempts to get beyond twentieth-century capitalism.

Jesuit Contribution to Science by Agustín Udías Pdf

This book presents a comprehensive history of the many contributions the Jesuits made to science from their founding to the present. It also links the Jesuits dedication to science with their specific spirituality which tries to find God in all things. The book begins with Christopher Clavius, professor of mathematics in the Roman College between 1567 and 1595, the initiator of this tradition. It covers Jesuits scientific contributions in mathematics, astronomy, physics and cartography up until the suppression of the order by the Pope in 1773. Next, the book details the scientific work the Jesuits pursued after their restoration in 1814. It examines the establishment of a network of observatories throughout the world; details contributions made to the study of tropical hurricanes, earthquakes and terrestrial magnetism and examines such important figures as Angelo Secchi, Stephen J. Perry, James B. Macelwane and Pierre Teilhard de Chardin. From their founding to the present, Jesuits have trodden an uncommon path to the frontiers where the Christian message is not yet known. Jesuits’ work in science is also an interesting chapter in the general problem of the relation between science and religion. This book provides readers with a complete portrait of the Jesuit scientific tradition. Its engaging story will appeal to those with an interest in the history of science, the history of the relations between science and religion and the history of Jesuits.

Philosophical Analysis in Latin America by J.J. Gracia,E. Rabossi,Enriq Villanueva,Marcelo Dascal Pdf

Historians of Latin American philosophy have paid relatively little attention to the development of philosophical analysis in Latin America. There are two reasons for this neglect: First, they have been primarily concerned with the forma tive period of philosophical development, in particular with the so called "founders" of La ti n American philosophy. And second. philosophical analysis did not become a noticeable philosophical trend in Latin America until recent years. True. a nunber of Latin American philosophers took notice of Moore. Russell. the members of the Vienna Circle and other important figures in the analytic movement qui te early. But these were isolated instances that lacked the sustained effort and broad base indispensible to make a serious impact in the development of Latin American philosophy. That has changed now. There are not only good numbers of philosophers who work within the analytic tradition, but also some journals and institutes dedicated to the analytic mode of philosophizing. It is. therefore. most appropriate to publish a collection of articles which would introduce the reader of philosophy to the most representative analytic material produced so far in Latin America. Indeed. it is not only appropriate. but also necessary. since most of the published analytic literature to date is scattered in various journals, sometimes of difficult access. Moreover, not all that has been published is representative of the best already produced and of the potential that the movement has in Latin America.

An Architectonic for Science by W. Balzer,C.U. Moulines,J.D. Sneed Pdf

This book has grown out of eight years of close collaboration among its authors. From the very beginning we decided that its content should come out as the result of a truly common effort. That is, we did not "distribute" parts of the text planned to each one of us. On the contrary, we made a point that each single paragraph be the product of a common reflection. Genuine team-work is not as usual in philosophy as it is in other academic disciplines. We think, however, that this is more due to the idiosyncrasy of philosophers than to the nature of their subject. Close collaboration with positive results is as rewarding as anything can be, but it may also prove to be quite difficult to implement. In our case, part of the difficulties came from purely geographic separation. This caused unsuspected delays in coordinating the work. But more than this, as time passed, the accumulation of particular results and ideas outran our ability to fit them into an organic unity. Different styles of exposition, different ways of formalization, different levels of complexity were simultaneously present in a voluminous manuscript that had become completely unmanageable. In particular, a portion of the text had been conceived in the language of category theory and employed ideas of a rather abstract nature, while another part was expounded in the more conventional set-theoretic style, stressing intui tivity and concreteness.
