Géneros discursivos de la memoria en clave literaria : los días iniciales de Joselín Cerda Rodríguez
Resumo:
Siendo el de las memorias un género legendario, hay que reconocer que su producción y posterior estudio ha cobrado particular auge en las últimas tres décadas. Si bien en el panorama sobre la escritura literaria en Catamarca, se conocen trabajos sobre las posibilidades de este género, están acotados a la poesía o a un texto como Niñez en Catamarca de Gustavo Gabriel Levene. Un aspecto probablemente distintivo de esta comunicación sea el corpus literario constituido por los relatos que integran Los días iniciales (1993) de Joselín Cerda Rodríguez, un escritor cuya obra constituye un caso infrecuente, por su autoafirmación étnica y por la textualización del yo en la reconstrucción de la memoria personal y colectiva. Interesa indagar: cómo el discurso construye las representaciones de la memoria personal; cuáles son las huellas del enunciador y cuáles las relaciones entre el yo autorial y el yo narrador en los enunciados narrativos; cuáles son las diferentes modalidades discursivas del género que exhibe la construcción de los textos. En relación con este último aspecto, importa considerar el plan de escritura de los relatos y la intercalación de recuerdos de infancia y de juventud, retratos físicos y morales, descripción de caracteres, evocación subjetiva y narración propiamente dicha. El abordaje previsto se encuadra en el marco teórico y metodológico provisto por el Análisis del Discurso (AD) y, en particular, sigue las propuestas de la Teoría de la Enunciación, la Lingüística del Texto y la Teoría Literaria, a partir de compatibilidades conceptuales que posibilitan integrar las distintas perspectivas teóricas. A través de este primer acercamiento al universo literario de Joselín Cerda Rodríguez se espera poder demostrar que la recuperación y preservación de la memoria personal, como colectiva constituye un punto de apoyo determinante en la plasmación de una cosmovisión singular e infrecuente.

The Albian/Cenomanian strata in Hole 530A are organically richer than are the post-Cenomanian strata. Organic matter is thermally immature and appears to be of dominantly marine origin with either variable levels of oxidation or variable amounts of terrestrial input. Geochemical data alone cannot establish whether the black shales present in Hole 530A represent deposition within a stagnant basin or within an expanded oxygen-minimum layer

LECO analysis, pyrolysis assay, and bitumen and elemental analysis were used to characterize the organic matter of 23 black shale samples from Deep Sea Drilling Project Leg 93, Hole 603B, located in the western North Atlantic. The organic matter is dominantly gas-prone and/or refractory. Two cores within the Turonian and Cenomanian, however, contained significant quantities of well-preserved, hydrogen-enriched, organic matter. This material is thermally immature and represents a potential oil-prone source rock. These sediments do not appear to have been deposited within a stagnant, euxinic ocean as would be consistent with an "oceanic anoxic event." Their organic geochemical and sedimentary character is more consistent with deposition by turbidity currents originating on the continental shelf and slope.

Ecological studies have demonstrated the role of competition in structuring communities; however, the importance of competition as a vehicle for evolution by natural selection and speciation remains unresolved. Study systems of insular faunas have provided several well known cases where ecological character displacement, coevolution of competitors leading to increased morphological separation, is thought to have occurred (e.g., anoline lizards and geospizine finches). Whiptail lizards (genus Cnemidophorus) from the islands of the Sea of Cortez and the surrounding mainland demonstrate a biogeographic pattern of morphological variation suggestive of character displacement. Two species of Cnemidophorus occur on the Baja peninsula, one relatively large (Cnemidophorus tigris) and one smaller (Cnemidophorus hyperythrus). Oceanic islands in the Sea of Cortez contain only single species, five of six having sizes intermediate to both species found on the Baja peninsula. On mainland Mexico C. hyperythrus is absent, whereas C. tigris is the smaller species in whiptail guilds. Here we construct a phylogeny using nucleotide sequences of the cytochrome b gene to infer the evolutionary history of body size change and historical patterns of colonization in the Cnemidophorus system. The phylogenetic analysis indicates that (i) oceanic islands have been founded at least five times from mainland sources by relatives of either C. tigris or C. hyperythrus, (ii) there have been two separate instances of character relaxation on oceanic islands for C. tigris, and (iii) there has been colonization of the oceanic island Cerralvo with retention of ancestral size for Cnemidophorus ceralbensis, a relative of C. hyperythrus. Finally, the phylogenetic analysis reveals potential cryptic species within mainland populations of C. tigris.
