La font de l’editio princeps d’Ausiàs March

Els stemmata codicum d’Amadeu Pagès i de Robert Archer ofereixen, com els autors mateixos preveien, resultats amb caràcter provisional i aproximat fins que no es revisen les relacions genealògiques de cadascun dels poemes i de cadascun dels cançoners d’Ausiàs March, de manera individual i completa. A partir d’aquesta premissa, aquest treball analitza els vincles de l’editio princeps marquiana a partir de la revisió de tots els poemes que conté, la qual cosa ha permés reinterpretar el seu lloc en l’stemma codicum i determinar la seua transcendència per a la tradició de March, ja que la seua font és propera a l’original i prèvia a la divisió en les principals branques textuals.

Comparison of the predictability of refractive cylinder correction by laser in situ keratomileusis in eyes with low or high ocular residual astigmatism

Purpose: To compare the manifest refractive cylinder (MRC) predictability of myopic astigmatism laser in situ keratomileusis (LASIK) between eyes with low and high ocular residual astigmatism (ORA). Setting: London Vision Clinic, London, United Kingdom. Design: Retrospective case study. Methods: The ORA was considered the vector difference between the MRC and the corneal astigmatism. The index of success (IoS), difference vector ÷ MRC, was analyzed for different groups as follows: stage 1, low ORA (ORA ÷ MRC <1), high ORA (ORA ÷ MRC ≥1); stage 2, low ORA group reduced to match the high ORA group for MRC; stage 3, grouped by ORA magnitude with low ORA (<0.50 diopters [D]), mid ORA (0.50 to 1.24 D), and high ORA (≥1.25 D); stage 4, high ORA group subdivided into low (<0.75 D) and high (≥0.75 D) corneal astigmatism. Results: For stage 1, the mean preoperative MRC and mean IoS were −1.32 D ± 0.65 (SD) (range −0.55 to −3.77 D) and 0.27, respectively, for low ORA and −0.79 ± 0.20 D (range −0.56 to −2.05 D) and 0.37, respectively, for high ORA. For stage 2, the mean IoS increased to 0.32 for low ORA. For stage 3, the mean IoS was 0.28, 0.29, and 0.31 for low ORA, mid ORA, and high ORA, respectively. For stage 4, the mean IoS was 0.20 for high ORA/low corneal astigmatism and 0.35 for high ORA/high corneal astigmatism. Conclusions: The MRC predictability was slightly worse in eyes with high ORA when grouped by the ORA ÷ MRC. Matching for the MRC and grouping by ORA magnitude resulted in similar predictability; however, eyes with high ORA and high corneal astigmatism were less predictable.

Arte contemporânea e meio ambiente no Museu Inhotim

Este estudo apresenta uma breve análise sobre o Museu Inhotim, considerado o maior museu a céu aberto do mundo. Nele, são expostas obras de Arte Contemporânea inseridas no meio ambiente, num processo de diálogo com a natureza, presente numa reserva florestal que era uma antiga fazenda. Entre jardins, arquitetura e arte, as obras também se relacionam entre si. No local são oferecidos passeios culturais, artísticos e educacionais, pois o museu conta com um setor educativo voltado para a educação através da reflexão sobre as obras de arte expostas e o meio ambiente, quanto à preservação do patrimônio ambiental e cultural. A arte, nesse contexto, ganha uma análise baseada em alguns conceitos sobre Arte Contemporânea, que se fundamentam em estudos propostos por autores como Giulio Carlo Argan, Umberto Eco, Michael Archer, Ernst Fischer, Fayga Ostrower, entre outros.
