O pensamento proto-nacionalizante de Fernando Oliveira e António Vieira : fundamentos sacralizantes da ideografia da nação portuguesa

«A escrita da história assume também uma dimensão profética e entra ao serviço da afirmação de uma consciência nacionalizante; e, através de uma hermenêutica inteligentemente orientada, os escritores/cartógrafos da nacionalidade formulam as suas críticas em relação ao presente e advertem os contemporâneos, em tom profético, em relação aos riscos do futuro. Mas esta nostalgia não se fecha em si própria. Transforma-se em instrumento de combate, de crítica, abrindo para o sentido da esperança no seu intento de desvelamento e antecipação teleológica.»

Fernando Nieto Cadena: la épica de lo cotidiano

Esta investigación se acerca a un corpus de poemarios que se enmarcan dentro de la épica de lo cotidiano, y pretende una aproximación a la poética de su autor, Fernando Nieto Cadena. En cuanto a esta lectura, he seguido categorías de Fredric Jameson y Terry Eagleton, en lo concerniente a ese sesgo ideológico que estos poemas demuestran. Pero me he inclinado por un marco que atienda esta poesía como fenómeno. También deseo despejar la pregunta acerca de las categorías precisas para acometer cierto movimiento en esta poesía, e inquirir sobre su caótico flujo. Quiero desentrañar la manera en que se construye esta lírica, poblada de elementos cercanos a los pobladores de la costa ecuatoriana, con mucho de influencia caribeña: son ellos quienes, al acercarse a esta poesía, podrán leer/se. A esto se añade una lectura que confirme los elementos que caracterizan el decir poético de Nieto Cadena. He hecho un recorrido a través de los títulos de Nieto para descubrir la tensión entre el elemento semántico y el fonético del texto, en pos de revisar los ritmos que este lenguaje ofrece.

El nuevo proyecto nacionalista de la literatura de la Guerra del Chaco en Bolivia

Esta tesis presenta un intento por estudiar algunos aspectos novedosos de la literatura referente a la Guerra del Chaco en Bolivia, como el nuevo proyecto nacionalista y racial que algunas obras de este periodo proponen. Estas obras presentan un nuevo discurso político que se convierte en cohesionador de las ideas y visiones sobre el país y sus habitantes y que posteriormente conformaron el discurso nacionalista de la revolución de 1952. Mi aproximación a estos textos se hace desde la discusión de los Estudios Culturales que atiende y cuestiona el proceso de formación de identidades desde la literatura, reconociendo en muchos casos la característica de 'invención' o 'construcción' de categorías tales como la nación, la historia, y la identidad. La literatura de la Guerra del Chaco construye nuevamente el mito de una nación homogénea alrededor de algunos de sus rasgos y las características de ciertos sectores de la sociedad boliviana. Así, cumplen la función de reordenar el Estado ya que proponen una nueva relación de fuerzas entre los diferentes grupos raciales del país. La ideología nacionalista, cuyos primeros lugares de formación es la narrativa chaqueña, tiene como base tres ejes discursivos: la identificación del boliviano con la tierra; su posicionamiento en favor de los indios y de los mestizos como parte y sujetos de la nación y por último es la identificación de los enemigos de la nación boliviana, los causantes de la guerra y de la consiguiente derrota. Esta identificación propone un marco de acción política para el futuro inmediato.

La teoría del aprendizaje significativo de David Ausubel en la aplicación de los textos de estudios sociales proporcionados por el Ministerio de Educación a los octavos años del Colegio Técnico Referencial "Luis Fernando Ruiz" de Latacunga, provincia de Cotopaxi, en el año lectivo 2012-2013

En momentos en que la principal preocupación es mejorar la calidad del aprendizaje (enseñanza de calidad), el docente debe encontrar los medios más efectivos para alcanzar los objetivos educativos y de esta manera lograr un aprendizaje significativo. El concepto de aprendizaje significativo fue desarrollado por David Ausubel para tratar de comprender desde el punto de la psicología, como se produce el aprendizaje en el sujeto, así como sus limitaciones para lo cual relacionó las prácticas educativas de entonces con su teoría. El proceso demanda, además de la mediación efectiva del docente, del apoyo de materiales educativos que a decir de Ausubel son parte fundamental en el proceso del aprendizaje significativo, en este caso el material potencialmente significativo. Esta investigación efectúa un análisis de un texto escolar de Estudios sociales para octavo año, con el fin de establecer si este permite o dificulta el aprendizaje significativo en el contexto de la reflexión teórica de Ausubel. Aunque el objeto de estudio es el texto de trabajo de los estudiantes, se utilizó como referente del aprendizaje a docentes y estudiantes del Colegio Técnico Referencial “Luis Fernando Ruiz con el fin de lograr una mejor estimación de la efectividad del texto para apoyar el aprendizaje.

Checklist and morphometry of benthic cnidarians from the Fernando de Noronha Archipelago, Brazil

The Fernando de Noronha Archipelago (Pernambuco State, Brazil), a national marine park, is formed by 21 islands and islets of volcanic origin. An update of the checklist of the benthic cnidarians from some of the archipelago`s reef environments, as well as a study of their corals and calcified hydroids morphometry, was the major goal of this work. Fieldwork was undertaken in February 2005 and in April 2006 and observations were carried out at 13 stations during snorkeling and/or scuba diving up to 30 m deep. Thirty-four species of cnidarians were recorded, of which 17 are new occurrences for the studied area. When added to the species previously listed in the literature, the total number of benthic cnidarians recorded for the Archipelago increases to 57. Stephanocoenia michelini, a new occurrence of zooxanthellate coral, is worthy of mention, as well as the calcified hydroid Millepora braziliensis. Mussismilia hispida tenuisepta showed several variations among its skeletal characters that surpassed the limits of intraspecific morphological variation when compared to those of Mussismilia hispida.

A comparative study of cleaning activity of two reef fishes at Fernando de Noronha Archipelago, tropical West Atlantic

Cleaner fishes are usually classified as obligate or facultative cleaners according to their diet and the extent to which their nutritional requirements in the different ontogenetic stages are gained from cleaning. While obligate cleaners clean throughout their lives and ingest mainly food taken from the clients` body surface, facultative cleaners clean only as juveniles and have a broader diet. In addition, some facultative cleaners may experience a relatively higher predation risk, and thus rarely interact with piscivorous fishes. Despite these acknowledged differences, there are very few studies that compare cleaning activity of obligate and facultative cleaners within the same area. Cleaning activity of the obligate cleaner goby Elacatinus cf. randalli and the facultative cleaner wrasse Thalassoma noronhanum were comparatively examined at Fernando de Noronha Archipelago, tropical West Atlantic. The client assemblage attended by the two cleaners differed, as the goby attended a slightly greater diversity of species (22), mostly piscivores and zoobenthivores, and the wrasse attended fewer species (19), mostly planktivores. Chromis multilineata was the most common client species of both cleaners, although body size (which is expected to be positively correlated to clients` ectoparasite load) of C. multilineata individuals attended by the goby was larger than that of the individuals attended by the wrasse. Despite such differences, T. noronhanum showed a surprisingly species-rich client assemblage when compared with other cleaners of the genus Thalassoma. In addition, the frequency and time spent on cleaning interactions, as well as the number of client species attended per 10-min period, was similar for both cleaner species, which indicate that they have important yet complimentary ecological roles in the reef community at Fernando de Noronha Archipelago.

A geochemical and lead isotopic record from a small pond in a remote equatorial island, Fernando de Noronha, Brazil

A 72 cm long core was collected from Lagoa da Viracao (LV), a small poind in the Fernando de Noronha island, northern Brazil. Sediments from the lower section of the core (20-72 cm depth) contain essentially mineral matter, while in the upper section (0-20 cm depth) mineral matter is mixed with organic matter. Lithogenic conservative elements - Si, Al, Fe, Ti, Co, Cr, Cu, Ba, Ga, Hf, Nb, Ni, Y, V, Zn, Zr and REE - exhibit remarkably constant values throughout the core, with concentrations similar to those of the bedrock. The vertical distribution of soluble elements - Ca, Mg, Na, K, P, Mn and Sr - is also homogeneous, but these elements are systematically depleted in relation to the bedrock. LOI, TOC, Br, Se, Hg and Pb, although showing nearly constant values in the lower section of the core, are significantly enriched in the upper section. The concentration profiles of Br and Se suggest that they may be accounted for by natural processes, related to the slight affinity of these elements for organic matter. On the other hand, the elevated levels of Hg and Pb in recent sediments may be explained by their long-range atmospheric transport and deposition. Furthermore, the isotopic composition of Pb clearly indicates that anthropogenic sources contributed to the Pb burden in the uppermost pond sediments.

Mg(2+) Ions Bind at the C-Terminal Region of Skeletal Muscle alpha-Tropomyosin

Tropomyosin (Tm) is a dimeric coiled-coil protein that polymerizes through head-to-tail interactions. These polymers bind along actin filaments and play an important role in the regulation of muscle contraction. Analysis of its primary structure shows that Tm is rich in acidic residues, which are clustered along the molecule and may from sites for divalent cation binding. In a previous study, we showed that the Mg(2+)-induced increase in stability of the C-terminal half of Tin is sensitive to imitations near the C-terminus. In the present report, we study the interaction between Mg(2+) and full-length Tin and smaller fragments corresponding to the last 65 and 26 Tin residues. Although the smaller Tin peptide (Tm(259-284(W269))) is flexible and to large extent unstructured, the larger Tm(220-284(W269)) fragments forms a coiled coil in solution whose stability increases significantly in the presence of Mg(2+). NMR analysis shows thin Mg(2+) induces chemical shift perturbations in both Tm(220-284(W269)) and Tm(259-284(W269)) in the vicinity of His276, in which are located several negatively charged residues.

"¡Cáncer es una mujer pegada como una sanguijuela sesenta años succionándole el alma!" : Un examen de los rasgos misóginos en la novela El desbarrancadero de Fernando Vallejo

El desbarrancadero, published in 2001 by Colombian author Fernando Vallejo is foremost a moving story about brotherly love, but it is also a highly critical novel that lashes out on a number of phenomena such as the catholic church, the Pope and the very idea of religion. It also addresses the poverty of Colombia, its corrupt politicians, the drug trade, viral diseases and animal abuse to mention a few more subjects. This essay however, does not aim to explore any of the above mentioned matters but rather examine how women are portrayed in this novel. The objective of this investigation, based on feminist theories, is to establish the very clear presence of misogyny attitudes.
