Análisis de las Relaciones Internacionales argentinas a partir de la construcción de identidad en los medios, la marca país y los espacios de participación ciudadana como factores domésticos de la política exterior.

El presente proyecto se propone integrar en una investigación tres dimensiones de la proyección identitaria de Argentina en el sistema internacional, como son la construcción mediática de la realidad, las estrategias de comunicación y participación de la sociedad civil y las definiciones en torno a la marca país. En tal sentido, se explorará la incidencia de estas tres dimensiones en la política exterior argentina en el período 2003-2011. Se parte del supuesto de que las producciones periodísticas se alejan cada vez más del ideal de política de comunicación exterior, al tiempo que se acercan en alianzas a las entidades de participación ciudadana. Esta relación muchas veces supera el impacto y construcción de realidad hacia afuera de aquellas estrategias de comunicación formales que diseña el estado argentino. Por un lado, la influencia de la producción mediática, de la sociedad civil y de la marca país no han sido consideradas en forma acabada en el estudio de las relaciones internacionales, a pesar de que los paradigmas actuales les otorgan a estas dimensiones un papel relevante en la construcción de imagen y posicionamiento internacional de los países. Por otro lado, la identificación de estas dimensiones como factores que inciden en la política exterior dan cuenta de un cambio de paradigma en las relaciones internacionales en épocas recientes, en tanto se suman a las dimensiones tradicionales vinculadas al paradigma realista. Finalmente, los hallazgos de este estudio servirán de base para el diseño de una política exterior que amplíe las dimensiones exclusivas del ámbito diplomático, a la vez que integre políticas dispersas relativas a comunicación, medios, participación ciudadana y marca país.

Contribuição ao conhecimento da sistemática e biologia de buprestídeos minadores do gênero Pachyschelus Solier, 1833: (Coleoptera, Buprestidae)

Buprestid leaf-miners are generally included in the subtribe Trachytes. The genera belonging to this subtribe are commonly very rich in number of species and their systematics envolves huge difficulties. On the other hand the biological knowledge on those insects is very poor. The A. tries to clarify the systematical status of two species of Pachyschelus - P. subundulatus Kerr. and P. fulgidipennis Lucas, and redescribes also P. binderi Obenberger. The hosts of the first two species are recorded, namely: Terminalia catappa (Combretaceae) - host-plant of P. subundulatus and Luhea spp. (Tiliaceae) - host-plant of P. fulgidipennis. The mines, developmental stages and habits of the three species are described and is made a full redescription of the adults, both male and female. The study is based on reared material from mined leaves, as well as insects assembled in several brazilian collections, both private and public ones. The importance of some biological facts as well as some morphological characters are stressed. The knowledge of the host-plants and the shape and other structural features of the mine were found to be helpfull to the identification of the species. Some morphological features of adults also prooved to be of systematical value. Besides the female pygidium and the male genitalia, the tibiae of the third pair of legs show some intersting structural details, reasonably alike in both sexes and quite different in each species.

Estudos taxionômicos e biológicos sôbre buprestídeos minadores do gênero Pachyschelus solier, 1833, com a descrição de uma espécie nova (Insecta, Coleoptera)

This paper deals with two Brazilian species of the genus Pachyschelus Sol., namely: P. urvillege sp. n. and P. mimus Obenberger, 1925. P. urvillege sp. n. is described based on specimens reared from leafmined Urvillea glabra Cam. (Sapindaceae); it seems to be related to P. vanrooni Obenb., 1923, from which it can be distinguished by the absence of sexual dichroism, structural details of female pygidium and, as supposed, by the male genitalia (still unknown in P. vanrooni). P. mimus Obenberger, 1925, was reared from Psidium araça Raddi (Myrtaceae), and the male allotype is described. Oviposition, larval cephalic capsules and mines of both species are described, as well as other developmental stages of P. urvilleae. Some larvae of the latter were found parasitized by Tetrastichus sp.

Notas sôbre o gênero Colobogaster Solier, 1833, com a descrição de duas novas espécies da Região Amazônica: (Coleoptera, Buprestidae)

The study of materials belonging to several brazilian collections led us discover 2 new species of the genus Colobogaster which are here described. C. seabrai sp. n. seems to be related to C. puncticollis Waterhouse, 1882, from which it can be distinguished by: a) apical alitral tooth placed suturally, b) pronotum with 3 pairs of depressions, the 1st. pair transversal and conigous to the 2nd one, c) elitral suture brilliantgreen coloured but not the marginal edge, d) front without a horse-shoe shaped structure, e) pronotum with the discal region concolor. The structures of pronotum, the elitral and pronotal colour paterns and the genial morphology separate this one from other species of the genus. C. paraensis sp. n. is closely related to C. cupricollis Kerremans, 1897, but it is distinguished by the absence of depressions on the pronotum, by the elitral tooth placed suturally, by the abscence of humeral rip and by the general colour. Eleven other species were studied and their apical segment of the abdomen and scutellum were illustrated. It was also established the synonymy of C. ecuadoricus Obengerger, 1926.
