Fruizione, criterio, piacere: la persistenza dei temi cirenaici nell'estetica postmoderna
No full textLa riproposizione organica dei testi originali della Scuola cirenaica con traduzione a fronte vuole oggi rappresentare un duplice tentativo: essere un utile strumento per tutti coloro che desiderano confrontarsi con le fonti di una delle scuole socratiche più affascinanti e nei secoli fraintese e, al contempo, fornire l'opportunità per una rilettura che vada oltre la mera prospettiva filologica. Ricchi e numerosi sono gli spunti di riflessione che le posizioni edoniste dei filosofi di Cirene ancora oggi porgono agli studiosi, spesso sottoforma di provocazioni che partendo dall’ambito etico giungono a ribadire la centralità del dato fruitivo all’interno di un’estetica fortemente legata alle polarità di “piacere” e “percezione”. Attraverso la persistenza di tali tematiche e l'individuazione delle loro radici nella filosofia antica emerge come i grandi temi dell'estetica contemporanea, messi alla prova quotidianamente dal confronto con gli oggetti, con i sensi, con i giudizi, con la circoscrizione del concetto stesso di piacere, possano attingere elementi e stimoli di grande ricchezza
Waldick Soriano e o mistério do brega
No full textEste artigo analisa a trajetória do cantor Waldick Soriano e a repercussão da chamada música brega no Brasil. O início da carreira, alguns dos sucessos e polêmicas do artista são relatados em um contexto que vai do governo JK, nos anos 50, à ditadura militar, na década de 70, quando Waldick também foi censurado. A partir de pistas fornecidas por etimólogos e historiadores, é esclarecida a origem da palavra "brega" e a singularidade desse estilo musical. O texto também analisa por que a música brega é rejeitada pelas elites culturais do país, e o que a diferencia do repertório da chamada MPB, a batalha pela memória na música brasileira e o lugar de Waldick Soriano no imaginário popular.This article analyzes the career of the singer Waldick Soriano and the impact of the music referred to as brega [tacky, out of taste] in Brazil. It narrates the beginning of his career, some of the artist\u27s hits and controversies in a period spanning from the 1950s - time of Juscelino Kubitschek\u27s presidency - to the military dictatorship in the 1970s, when Waldick was also censored. By taking cues from etymologists and historians the origin of the word brega is explained, and also the singularity of this musical style. The author also analyzes why brega music is unappreciated by the cultural elites of the country, and what distinguishes it from the so called MPB repertoire
BICA and Random Subspace ensembles for DNA microarray-based diagnosis
No full textWe compare two ensemble methods to classify DNA microarray data. The methods use different strategies to face the course of dimensionality plaguing these data. One of them projects data along random coordinates, the other compresses them into independent boolean variables. Both result in random feature extraction
procedures, feeding SVMs as base learners for a majority voting ensemble classifier. The classification capabilities are comparable, degrading on instances that are acknowledged anomalous in the literature
Some reptiles from Marsa El Brega, Libya (Reptilia: Chamaeleonidae, Gekkonidae, Phyllodactylidae, Lacertidae and Scincidae)
No full textThe terrestrial reptile fauna of Libya is under-documented due to limited research stemming from political instability. The author conducted fieldwork in Libya, specifically in Marsa El Brega, during two visits in 2013 and 2014. Out of the 25 species known from Libya's historic Cyrenaica province, 7 species were identified in the surveyed area
Penetration of amphotericin B in human lung tissue after single liposomal amphotericin B (AmBisome) infusion
No full textThe distribution of amphotericin B in lung tissue was studied in 18 patients with primary or secondary lung cancer who underwent thoracotomy and pulmonary resection. At different times before surgery the patients were treated with liposomal amphotericin B 1.5 mg/kg by i.v. infusion over 1h. Blood and lung tissue samples were collected during surgery (one subjects for each collecting time) and assayed for amphotericin B levels by HPLC. Due to surgical requirements, it was possible to obtain data from the 10th to the 25th h after the end of infusion. Plasma amphotericin B concentrations progressively decreased from 3.4 mcg/ml at the 10th h to 1 mcg/ml at the 25th h after the end of intravenous infusion. In lung tissue samples the lowest amphotericin B concentration (about 1 mcg/g) was observed at the 10th h, then a progressive increase was observed with the highest value (2.5 mcg/g) determined at the 25th h
