Il dialogo pseudo-platonico Amanti: la polemica contro Isocrate e l’Accademia sotto il magistero di Platone
No full textIn this paper, the author analyses the dialogue Lovers or Rivals. Some scholars argue in favour of Plato’s authorship, while others agree on its inauthenticity. The thesis of its inauthenticity will be defended without reappraising and developing the most prevalent hypothesis, namely that the dialogue was composed in the third century BCE as a pamphlet against the Peripatetic school. In fact, the author advances the hypothesis that the Lovers were written by a disciple of Plato in the fourth century BCE, and that the dialogue clearly attacks Isocrates and, in particular, his conception of philosophy described for example in his Antidosis. The author will argue that the dialogue possesses a protreptic intent and perhaps addresses some of those issues that were most considered by Plato himself: finding a proper definition of philosophy and encouraging philosophers to engage in politics
Estimating the supply of biomass from short-rotation coppice in England, given social, economic and environmental constraints to land availability
No full textBackground: biomass has been identified as an important source of renewable energy. However, growing demand for dedicated energy crops could lead to conflicts with food production and ecosystem services. This study uses a geographic information systems-embedded modeling approach to assess the spatial supply of short-rotation coppice, taking into account social, economic and environmental constraints. Results: results suggest that 7.5 million tons of biomass (from short-rotation coppice) is realistically available in England. Such production would require 0.8 million ha and could be grown almost entirely on poor quality marginal lands. Conclusion: we therefore conclude that short-rotation coppice energy crops have the potential to play an important role in meeting UK renewable energy targets without compromising environmental sustainability or food productio
The technical potential of Great Britain to produce ligno cellulosic biomass for bioenergy in current and future climates
No full textProcess and empirical-based models that describe lignocellulosic biomass yield of the perennial energy grass Miscanthus (MiscanFor©), short rotation coppice (SRC) trees and shrubs, poplar and willow (ForestGrowth-SRC) and a number of short rotation forest trees (ESC-CARBINE), were used to estimate the yield potential for current and future climates across Great Britain (GB). In current climates, modelled yields for all feedstock crops varied between 8.1 and 10.6 Mg dry weight (DW) ha?1 yr?1 with willow SRC and poplar SRF producing the lowest and highest yields respectively. For the medium emissions scenario (UKCP09) in 2050, mean yield for all feedstock crops varied between 7.6 and 12.7 Mg DW ha?1 yr?1 with willow SRC and poplar SRF once again the lowest and the highest recorded yields. There were clear geographical trends within GB. Miscanthus yield was higher than all others in the south-west (13.1 Mg DW ha?1 yr?1), SRC willow and SRC poplar in the north-west (12.1–15.8 Mg DW ha?1 yr?1) and in the midlands and south-east, SRF poplar was the highest yielding (10.5–11.6 Mg DW ha?1 yr?1). These geographical trends changed little with climate out to 2050, with mean yield of each ‘best feedstock’ increasing from 12.7 to 14.2 Mg DW ha?1 yr?1. Out to 2050, SRC declined slightly and Miscanthus and SRF poplar increased as the ‘best feedstock’ option. Except for a few localized examples, only SRF poplar had a higher yield than SRC or Miscanthus. These data suggest that in current and future climates, lignocellulosic biomass plantation species can be selected and optimized for best yield performance in different regions of GB. This modelling framework provides a valuable starting-point for which to test the performance of new genetic material, as this becomes available and parameterized for the models and socio-economic scenarios that may impact on the bioenergy industry

Introducción a la propuesta contable de García-Casella
No full textEl presente trabajo constituye una introducción al pensamiento contable del profesor argentino Carlos Luis García-Casella, quien ha propuesto y desarrollado una teoría general de la contabilidad a partir de los trabajos de Richard Mattessich, que permite superar las concepciones que limitan el saber contable a la economía, la administración o las finanzas. Establece el autor un alcance amplio para la contabilidad que sustenta los modelos contables financiero, administrativo, económico, social y público; con representaciones cualitativas y cuantitativas, monetarias y no monetarias.The present work embodies an introduction to the thoughts on accountancy developed by Argentinian professor Carlos Luis García-Casella, who has proposed the development of a general accounting theory departing from the work of Richard Matterssich, going beyond the idea of restraining accounting knowledge to areas such as economy, management or financing. The author establishes a wide connection for Accountancy, allowing it to support the financial, managerial, economical, social and political accounting models, using qualitative and quantitative, monetary and non-monetary representations.O presente trabalho constitui uma introdução ao pensamento contabilístico do professor argentino Carlos Luís García-Casella, quem propus o desenvolvimento duma teoria geral da contabilidade a partir dos trabalhos de Richard Mattessich.

Claude Debussy. Modèle à suivre ou à éviter ? La réception du maître français chez Alfredo Casella
No full textTout au long de sa carrière de compositeur, Alfredo Casella (1883-1947) semble faire un cas particulier du maître français Claude Debussy. Lors de sa période de formation en France (1896-1915) Debussy est une source d’inspiration majeure pour le jeune compositeur en quête d’un style qui lui soit personnel. De retour en Italie, Casella encourage les jeunes compositeurs à s’inspirer des techniques européennes, incluant celles de Debussy, pour moderniser la musique instrumentale italienne. Cependant, avec la mise de l’avant du passé musical italien, pour la création d’un art national, Casella adopte progressivement une position différente, voire diamétralement opposée, face à la musique de Debussy. Le compositeur français n’est alors plus un modèle, ni même un « rêve pour les générations futures », mais plutôt, si l’on en croit Casella, l’auteur d’un langage tout à fait incompatible avec « l’esprit profondément italien ». Nous proposons une étude de nature critique, historique et esthétique d’oeuvres de Casella datant de 1902 à 1930. Nous tenterons d’établir un lien méthodologique entre les affirmations et les opinions dans les écrits de Casella et leur application dans ses compositions par l’entremise de l’argumentation développée par le musicien.Throughout his career, Alfredo Casella (1883-1947) seemed to make a particular case of French master Claude Debussy. During his training period in France (1896-1915), Debussy was a major source of inspiration to the young composer seeking his own personal style. Back in Italy, Casella encouraged young composers to inspire themselves of European techniques, including those of Debussy, to modernize the Italian instrumental music. However, with the promotion of the Italian musical past, aiming the creation of a national art, Casella gradually adopted a different position, event diametrically opposed, regarding Debussy’s music. Then the French composer is not considered as a model anymore, nor even, a “dream for the future generations,” but rather, according to Casella, the author of a language entirely incompatible with “the profoundly Italian spirit.” We propose a critical, historical and aesthetical study of Casella’s works from 1902 to 1930. We shall try establishing a methodological link between the assertions and opinions in Casella’s writings and their application in his musical works, by the means of the argumentation developed by the musician

La donna, il diritto e il patrimonio nella testimonianza libaniana
No full textIn this study about the role of Antiochian imperial women I aim at investigating the interrelationship between law and society and at analysing the way social changes lead to birth of new laws, in the period marked by a gradual replacement inside the Mediterranean world. Leafing through the numerous pages dedicated to Antiochene society in the 4th century by an author such as Libanius, who has always set himself up as a strenuous defender of the Hellenic tradition and champion of the ancient civic ideal, and who was influenced less than anyone else by the attraction of the new ideas of Christianity, a pattern emerges thanks to which we can understand the degree of consideration to which women being was held in Late Antiquity, coinciding with a new morality of the couple, which tended to make marriage a conjugal community
