Funciones de la novela sentimental hispanoamericana durante el siglo XIX

Se analizará cómo funcionan los textos sentimentales hispanoamericanos en los lectores según dos modos de concebir la recepción de estas obras: la lectura en un “microambiente" de un lector/a sentimental-individual y la lectura en un “macroambiente" de varios lectores de novelas sentimentales. Así también, se pretende fijar las características fundamentales de la narrativa sentimental hispanoamericana en un conjunto de textos representativos de esta modalidad literaria. A su vez, este análisis intenta ser una “nueva visión" de los textos enriquecida sobre todo con la ayuda valiosa de enfoques desde lo “literario-cultural" (Lander, 2003), lo “discursivo" (Barthes, [1977] 2002) y lo “sociológico" (Giddens [1992] 2004). En esta ocasión sólo nos ocuparemos de la narrativa del siglo XIX y el corpus de obras será el siguiente: Soledad (1847) y Memorias de un botón de rosa (1847, reeditada en 1907) de Bartolomé Mitre; Esther de Miguel Cané (1851); Martín Rivas (1862) de Alberto Blest Gana; Julia (1861) de Luis Benjamín Cisneros; La peregrinación de Bayoán (1861) de José María de Hostos; María (1867) de Jorge Isaacs; Clemencia (1869) de Ignacio Manuel Altamirano y Cumandá (1879) de Juan León Mera.

El pensamiento binario y sus salidas : hibridez, pluricultura, paridad y mestizaje

Tal como lo han analizado autores contemporáneos como E. Grüner, E. Lander y A. Mbembe, la forma que adopta el pensamiento occidental es binaria, es decir que se encuentra constituida por dos categorías exclusivas y excluyentes, por pares antagónicos, por polos opuestos. Binaria asimismo es la construcción de las identidades en Occidente, sean éstas identidades de género, de clase, étnicas o políticas. En el presente trabajo nos concentraremos en las teorizaciones de algunos autores del pensamiento poscolonial que, al cruzar las dimensiones ontológica, epistemológica y política de las cosmovisiones y de las identidades, aportaron elementos para la deconstrucción de este binarismo. H. Bhabha, R. Segato, R. Paiva y G. Anzaldúa delinearon, a nuestro entender, posibles salidas a esta cosmovisión identitaria, muy especialmente a través de sus conceptos clave de 'hibridez', pluricultura', 'paridad' y 'mestizaje'.

Emergencia y crecimiento de plántulas de variedades de albahaca (Ocimum basilicum L.) en condiciones salinas

La albahaca presenta variabilidad en la tolerancia al estrés salino y se considera una planta sensible a la salinidad al inicio del crecimiento. El objetivo del estudio fue determinar el efecto del NaCl en la emergencia y crecimiento de albahaca. Se utilizaron veinte variedades sometidas a 0; 50 y 100 mM de NaCl, en un diseño completamente al azar con cuatro repeticiones. Las variables medidas fueron porcentaje y tasa de emergencia, longitud de radícula, altura de plántula, biomasa fresca y seca de radícula y de parte aérea. Los resultados mostraron que la variedad con mayor porcentaje de emergencia fue Thai, mientras que Sweet Genovese y Napoletano exhibieron los menores porcentajes. La variedad Thai mostró la mayor tasa de emergencia y Sweet Genovese la menor. Sweet Dani, Thai, Italian Large Leaf y Red Rubin presentaron mayor longitud de radícula, mientras que Sweet Dani, Italian Large Leaf, Dolly y Emily mostraron mayor biomasa fresca y seca de radícula. Sweet Dani, Licorice, Genovese y Napoletano exhibieron mayor altura de plántula, mientras que Sweet Genovese, Thai y Dolly presentaron mayor biomasa fresca y seca de parte aérea. Se discute la respuesta diferencial de las variedades al NaCl en la emergencia de plántulas.

Revised age models and foraminiferal records obtained for the Last Interglacial period in six marine sediment cores

The dataset contains the revised age models and foraminiferal records obtained for the Last Interglacial period in six marine sediment cores: - the Southern Ocean core MD02-2488 (age model, sea surface temperatures, benthic d18O and d13C for the period 136-108 ka), - the North Atlantic core MD95-2042 (age model, planktic d18O, benthic d18O and d13C for the period 135-110 ka), - the North Atlantic core ODP 980 (age model, planktic d18O, sea surface temperatures, seawater d18O, benthic d18O and d13C, ice-rafted detritus for the period 135-110 ka), - the North Atlantic core CH69-K09 (age model, planktic d18O, sea surface temperatures, seawater d18O, benthic d18O and d13C, ice-rafted detritus for the period 135-110 ka), - the Norwegian Sea core MD95-2010 (age model, percentage of Neogloboquadrina pachyderma sinistral, sea surface temperatures, benthic d18O, ice-rafted detritus for the period 134-110 ka), - the Labrador Sea core EW9302-JPC2 (age model, percentage of Neogloboquadrina pachyderma sinistral, sea surface temperatures, benthic d18O for the period 134-110 ka).

Geochemistry and physics on sediment cores from the Peru Basin

We studied preservation/dissolution cycles and paleoproductivity in eight sediment cores from the Peru Basin south of the highly productive surface waters of the eastern equatorial Pacific. Stratigraphy is based on stable oxygen isotopes and on combined magnetostratigraphy and biostratigraphy. Sediment cores which span the last 8 m.y., were retrieved during cruise 79 with RV SONNE close to the carbonate compensation depth (CCD). In general, sediments show Pacific-type carbonate cycles. We interpret a pronounced carbonate peak between 6 and 7 Ma as the result of a western and northern extension of the highly productive Peru Current. Decreased carbonate contents from the late Miocene to the late Pliocene might be associated with a slow contraction of the latitudinal extent of the high-productivity belt north of the study areas. During the Pliocene, carbonate variations showed 400 kyr cycles indicating the growth and decay of ice sheets, which should have been associated with pulsations of the Antarctic ice cap. An abrupt collapse of the carbonate system occurred at 2.4 Ma. Higher frequency variations of the carbonate record indicate the major increase of the northern hemisphere glaciation. During the Quaternary, carbonate fluxes are high during glacials and low during interglacials. Large amplitude variations with long broad minima and maxima, associated with small migrations of the lysocline and the CCD (< 200 m), are indicative of the preservation/dissolution history in the Peru Basin. During the early Pleistocene, climatic forcing by the 41 kyr obliquity cycle is not observed in the carbonate record. During the last 800 kyr, variability in the carbonate record was dominated by the 100 kyr eccentricity cycle. Fluxes of biogenic material (calcium carbonate, organic carbon, opal, and barium) were greatest during glacials, which imply higher productivity and export production of the Peru Current during cold climatic periods. Dissolution was greatest during interglacials as inferred from the relatively poor preservation of planktonic foraminifera and from the low accumulation rate of carbonate. After the Mid-Brunhes Event (400 ka), we observe a plateaulike shift to enhanced dissolution and to intensified productivity.

Molecular differentiation by PCR-RFLP technique shows that Antarctic fishes of the genus Notothenia, claimed to be two species, are phenotypic varieties with the same genetic pattern (Table 1)

The taxonomy of Antarctic fishes has been predominantly based on morphological characteristics rather than on genetic criteria. A typical example is the Notothenia group, which includes N. coriiceps Richardson, 1844, N. neglecta Nybelin, 1951 and N. rossii Richardson, 1844. The Polymerase Chain Reaction and Restriction Fragment Length Polymorphism (PCR-RFLP) technique was used to determine whether N. coriiceps Richardson, 1844 and N. neglecta Nybelin, 1951 are different or whether they are the same species with morphological, physiological and behavioural variability. N. rossii was used as control. Mitochondrial DNA (mtDNA) was isolated from muscle specimens of N. coriiceps Richardson, 1844, N. neglecta Nybelin, 1951 and N. rossii, which were collected in Admiralty Bay, King George Island. The DNA was used to amplify a fragment (690 base pairs) of the mitochondrial gene coding region of NADH dehydrogenase subunit 2. Further, the amplicon was digested with the following restriction enzymes: DdeI, HindIII and RsaI. The results showed a variation of the digestion pattern of the fragment amplified between N. rossii, and N. coriiceps Richardson, 1844 or N. neglecta Nybelin, 1951. However, no differences were found between N. coriiceps Richardson, 1844 and N. neglecta Nybelin, 1951, on the grounds of the same genetic pattern shown by the two fish.
