La crisis financiera y la crisis de civilización

"La crisis financiera internacional que estamos atravesando es una oportunidad para comprender con mayor profundidad cómo funciona el sistema capitalista y las bases sobre las cuales está edificado. Toda crisis opera como una falla, en el sentido geológico del término. La falla, la ruptura, como señalara Heidegger, revela la existencia de lo que antes era obvio o que formaba el fondo sobre el cual organizamos nuestras vidas. Vivimos en un mundo organizado de cuya existencia y producción no nos percatamos mientras funciona. Cuando deja de hacerlo salta a la luz su carácter no natural, construido, histórico, y por tanto, perfectible. En este trabajo sostendré la hipótesis de que la actual crisis financiera es consecuencia de una asignación disfuncional del crédito a nivel global. Por tanto, las divergentes explicaciones técnicas al respecto diferirán en la idea de y lugar que asignen al crédito en el sistema económico. Lo que pueden parecen inocentes conceptos “técnicos” o “científicos” suponen, en verdad, una concepción del mundo, una ontología; más: una teología fundamental. Por ello en lo que sigue opondré a la explicación convencional de la crisis una interpretación alternativa a partir de la explanación del sistema económico que propone Bernard Lonergan, para pasar, en un segundo momento, a un nivel más fundamental de análisis que busca dar con los valores que sostienen la teoría económica capitalista..."

La civilización vasca medieval: vida(s), cotidiana(s), mentalidad(es) y cultura(s)

[ES]A lo largo de las páginas de este trabajo se pasa revista a diversas cuestiones que permiten realizar una aproximación a las diversas formas de vida cotidiana y mentalidad del País Vasco y Navarra durante los siglos bajomedievales. Esas cuestiones aluden al primum vivere, al ciclo vital, al control de la vida privada de los individuos y pública de las comunidades por parte de las autoridades, las fiestas, las supersticiones y distintos aspectos relativos a la cultura, como literatura, historiografía y arte.

Hydroacoustic evaluation of spawning red hind (Epinephelus guttatus) aggregations along the coast of Puerto Rico in 2002 and 2003

Red hind (Epinephelus guttatus) have been overfished in the Caribbean and were included with seven other regional grouper species deemed vulnerable to risk of extinction. The Puerto Rico Department of Natural and Environmental Resources desired to map spawning red hind aggregations within commonwealth waters as part of their resource management program for the species. Mobile hydroacoustic surveys were conducted over 3-day periods in 2002 and 2003, indexed to the full moon phase in February or March when red hind were known to aggregate. Four vessels concurrently sampled the southwest, south, and southeast coasts of Puerto Rico in 2002. In 2003, three vessels conducted complementary surveys of the northwest, north, and northeast coasts of the island, completing a circuit of the coastal shelf-spawning habitat. These surveys indicated that red hind spawning aggregations were prevalent along the south and west coasts, and sparse along the north coast during the survey periods. Highest spawning red hind concentrations were observed in three areas offshore of the west coast of Puerto Rico, around Mona and Desecheo islands (20,443 and 10,559 fish/km2, respectively) and in the Bajo de Cico seasonal closed area (4,544 fish/km2). Following both 2002 and 2003 surveys, a series of controlled acoustic measurements of known local fish species in net pens were conducted to assess the mean target strength (acoustic backscatter) of each group. Ten species of fish were measured, including red hind (E. guttatus), coney (E. fulvus), white grunt (Haemulon plumieri), pluma (Calamus pennatula), blue tang (Acanthurus coeruleus), squirrel fish (Holocentrus spp.), black durgeon (Melichtyhs niger), ocean file fish (Canthidermis sufflamen), ocean surgeon fish (Acanthurus bahianus), and butter grouper (Mycteroperca spp.). In general, the mean target strength results from the caged fish experiments were in agreement with published target strength length relationships, with the exception of white grunt and pluma.

Diet composition and prey selection of the introduced grouper species peacock hind (Cephalopholis argus) in Hawaii

The introduced grouper species peacock hind (Cephalopholis argus), was the dominant large-body piscivore on the Main Hawaiian Island (MHI) reefs assessed by underwater visual surveys in this study. However, published data on C. argus feeding ecology are scarce, and the role of this species in Hawaiian reef ecosystems is presently not well understood. Here we provide the first comprehensive assessment of the diet composition, prey electivity (dietary importance of prey taxa compared to their availability on reefs), and size selectivity (prey sizes in the diet compared to sizes on reefs) of this important predator in the MHI. Diet consisted 97.7% of fishes and was characterized by a wide taxonomic breadth. Surprisingly, feeding was not opportunistic, as indicated by a strongly divergent electivity for different prey fishes. In addition, whereas some families of large-body species were represented in the diet exclusively by recruit-size individuals (e.g., Aulostomidae), several families of smaller-body species were also represented by juveniles or adults (e.g., Chaetodontidae). Both the strength and mechanisms of the effects of C. argus predation are therefore likely to differ among prey families. This study provides the basis for a quantitative estimate of prey consumption by C. argus, which would further increase understanding of impacts of this species on native fishes in Hawaii.
