Billy Budd: de H. Melville a E. M. Forster, o la via Plutarquea vers Plató

L'objectiu d'aquest article és proposar i fonamentar una via plutarquea -no només Les Vides Paral·leles, sinó també L'Eròtic- vers el contingut platònic de Billy Budd de B. Britten amb libretto d'E. M. Fosrter en col·laboració amb Eric Crozier. H. Melville no cita pas Plutarc en la seva novel·la, però l'excel·lent coneixement dels textos de l'escriptor i filòsof grec per part d'E. M. Foster fa que aquesta hipòtesi sigui altament versemblant.

El objetivo de este artículo es proponer y fundamentar una vía plutarquea -no sólo Las Vidas Parelelas, sino tambén El Eròtico- al contenido platónico de Billy Budd de B. Britten con libreto de E. M. Foster en colaboración con Eric Crozier. H. Melville no cita a Plutarco en su novela, pero el excelente conocimiento de los textos del escritor y filósofo griego por parte de E. M. Forster hace que esta hipótesis sea altamente verosímil.

Billy Budd: from H. Melville to E. M. Forster, or Plutarch's way to Plató

The aim of this article is to propose and lay the foundations of a Plutarch's way ¿not only his Lives but also his Eroticus- to the Platonic content of Billy Budd by B. Britten with a libretto by E. M. Forster in association with Eric Crozier. Plutarch is not quoted in H. Melville¿s novel, but E. M. Forster¿s good knowledge of the texts by the Greek writer and philosopher makes this hypothesis quite credible

Environment conditions and biological innovations in the european agrarian growth, 1819-1939

The circumstances that were the driving forces behind Europe's economic growth beginning in the 19th century are diverse, and not easily prioritized. Until the 1970's, specifically, in Economy and Economic History, attention was focused on different institutional and technological variables, and various regularities were proposed. Nevertheless, new studies also underlined that the evolution of economic activity could not be understood considering only the new production possibilities offered by market economies. As a result, today it is also accepted that those processes can not be explained without considering two additional circumstances: the energy flows that sustained them, and the changes undergone in their transformation In this context, a question arises that takes on special importance. Which was the influence of the biological change in the economic growth?. A part of the flows of energy must be made into food, and this transformation can only happen with the participation.

Regional value added in Italy over the long run (1891-2001): linking indirect estimates with official figures, and implications

This paper presents value added estimates for the Italian regions, in benchmark years from 1891 until 1951, which are linked to those from official figures available from 1971 in order to offer a long-term picture. Sources and methodology are documented and discussed, whilst regional activity rates and productivity are also presented and compared. Thus some questions are briefly reconsidered: the origins and extent of the north-south divide, the role of migration and regional policy in shaping the pattern of regional inequality, the importance of social capital, and the positioning of Italy in the international debate on regional convergence, where it stands out for the long run persistence of its disparities.

Simone Weil i Bertrand Russell : Dues reflexions sobre la pau a l'Europa dels anys trenta

Simone Weil i Bertrand Russell havien defensat posicions pacifistes, però davant del nazisme van justificar la guerra. S'han destacat alguns elements de reflexió en el canvi d'actitud: la importància dels mitjans de comunicació, la del llenguatge i del vessant psicològic del poder, la construcció mediàtica de l'enemic i la transcendència política de l'actuació individual i social davant l'Estat.

El Lloc dels riscos naturals als Annales de Géographie (1891-1991)

L'étude des risques naturels est devenu un sujet de débat entre les géographes physiques français, de plus en plus conscients de l'exposition croissante des sociétés aux risques naturels et du besoin d'évaluer leurs compétences et leurs moyens d'intervention. Mais l'étude des risques naturels a aussi été un sujet récurrent dans l'histoire de la géographie française. Cet article prétend être une approche au traitement qu'a reçu ce thème dans les Annales de Géographie depuis sa création jusqu'h aujourd’hui. Après avoir distingué trois étapes (1891-1930, 1930-1975 et 1975-1991) on a établi les rapports existants entre les différents moments de la géographie française et l'étude des risques naturels et on a analysé autant le contenu des notices sur les divers évènements catastrophiques que les travaux des auteurs les plus représentatifs. I1 s'agit, en résumé, de proposer une réflexion sur la façon dont la géographie française a abordé ce sujet

"Maurice" de James Ivory . ¿Traïció a la Tradició Clàssica en adaptar la novel·la d'E. M. Forster?

D'acord amb els estudis sobre literatura i cinema i des del punt de vista de la influència de la Tradició Clàssica -Tradició Grega Clàssica, en aquest cas-, aquest article és una anàlisi acurada de les traïcions inevitables -fins a un cert punt- dels guionistes respecte dels textos literaris que adapten. Tanmateix, malgrat ser pràcticament inevitable, el Dr. Pau Gilabert Barberà indica quins són en opinió seva els límits que Ivory/Hesketh-Harvey no haurien d'haver ultrapassat a fir de no diluir el temperament hel·lènic de "Maurice" d'E. M. Forster.

"Maurice" de James Ivory . ¿Traición a la Tradición Clásica al adaptar la novela de E. M. Forster?

De acuerdo con los estudios sobre literatura y cine y desde el punto de vista de la influencia de la Tradición Clásica -Tradición Griega Clásica, en este caso-, este artículo es un análisis minucioso de las traiciones inevitables ¿hasta un cierto punto- de los guionistas a los textos literarios que adaptan. Sin embargo, a pesar de ser prácticamente inevitable, el Dr. Pau Gilabert Barberà indica cuáles son en su opinión los límites más allá de los cuales Ivory/Hesketh-Harvey no deberían haber ido a fin de no diluir el temperamento helénico de "Maurice" de E. M. Forster.

Spermiogenesis and spermatozoon ultrastructure of the bothriocephalidean cestode Clestobothrium crassiceps (Rudolphi, 1819), a parasite of the teleost fish Merluccius merluccius (Gadiformes: Merlucciidae)

Spermiogenesis and the ultrastructure of the spermatozoon of the bothriocephalidean cestode Clestobothrium crassiceps (Rudolphi, 1819), a parasite of the teleost fish Merluccius merluccius (Linnaeus, 1758), have been studied by means of transmission electron microscopy. Spermiogenesis involves firstly the formation of a differentiation zone. It is characterized by the presence of two centrioles associated with striated rootlets, an intercentriolar body and an electron-dense material in the apical region of this zone. Later, two flagella develop from the centrioles, growing orthogonally in relation to the median cytoplasmic process. Flagella then undergo a rotation of 90° until they become parallel to the median cytoplasmic process, followed by the proximodistal fusion of the flagella with the median cytoplasmic process. The nucleus elongates and afterwards it migrates along the spermatid body. Spermiogenesis finishes with the appearance of the apical cone surrounded by the single helical crested body at the base of the spermatid. Finally, the narrowing of the ring of arched membranes detaches the fully formed spermatozoon. The mature spermatozoon of C. crassiceps is filiform and contains two axonemes of the 9 + '1' trepaxonematan pattern, a parallel nucleus, parallel cortical microtubules, and electron-dense granules of glycogen. The anterior extremity of the gamete exhibits a short electron-dense apical cone and one crested body, which turns once around the sperm cell. The first axoneme is surrounded by a ring of thick cortical microtubules that persist until the appearance of the second axoneme. Later, these thick cortical microtubules disappear and thus, the mature spermatozoon exhibits two bundles of thin cortical microtubules. The posterior extremity of the male gamete presents only the nucleus. Results are discussed and compared particularly with the available ultrastructural data on the former 'pseudophyllideans'. Two differences can be established between spermatozoa of Bothriocephalidea and Diphyllobothriidea, the type of spermatozoon (II vs I) and the presence/absence of the ring of cortical microtubules.

Dover, Kenneth James: "Homosexualidad griega", Barcelona

Publicado en inglés en el año 1978, el libro de K. J. Dover Homosexualidad griega se considera el primer ensayo serio dedicado a la homosexualidad masculina en la Grecia clásica. Éste y otros trabajos del mismo autor tuvieron influencia importante en los dos volúmenes centrados en la antigüedad de Histoire de la sexualité de Michel Foucault, de quién la edición española incluye como prólogo la reseña que el filósofo escribió a raíz de la edición francesa de la obra de K. J. Dover en 1982. La presente edición incluye, además, un actualizado apartado bibliográfico sobre la sexualidad en el mundo grecorromano y la homosexualidad en Grecia.

Ultrastructure of the spermatozoon of the digenean Lecithocladium excisum (Rudolphi, 1819) (Hemiuroidea: Hemiuridae), a parasite of marine teleosts in Senegal

The present study describes the ultrastructure of the mature spermatozoon of Lecithocladium excisum (Rudolphi, 1819) (Digenea: Hemiuroidea: Hemiuridae) from the stomach of the marine teleost Scomber japonicus Houttuyn (Scombridae) captured in the Atlantic Ocean, off Dakar (Senegal). The ultrastructural organization of the spermatozoon of L. excisum follows the general model described in most digeneans. It presents two axonemes of the 9+'1' pattern of the Trepaxonemata, nucleus, mitochondrion and parallel cortical microtubules, among other characters. However, some particularities of the spermatozoon of L. excisum are (i) the presence of a membranous ornamentation not associated with cortical microtubules in its anterior extremity, (ii) the presence of a very reduced number of cortical microtubules located only in the ventral side of the spermatozoon and (iii) the absence of several structures described in most digeneans such as spine-like bodies and cytoplasmic expansions.
