In the Era of Computers, Internet and Multimedia, are we still Teaching Composers to become Chapel-Masters?

The ongoing paradigm shift from traditional methods of teaching music composition towards new approaches based on computer technology for sound production is the main focus of the article. The paper reviews the evolution of teaching methods throughout the Classical, Romantic and Modern periods, demonstrating how certain standard practices from former ages, based on the professional profile of the Chapel-Master, become theoretical golden principles for subsequent periods. After the French Revolution the traditional method of individual practical exchange between master and disciple was upgraded at the Conservatory. Classes for groups of students required a new approach based on theory abstraction. Although none of these teaching methods have been abandoned up today, a new paradigm appears when the tools of computer technology became widespread. An unpredictable equilibrium between the traditional methods and the new techniques of computer-assisted or computer-generated music composition tends to emerge

Hibridismo, Consistência e Processos de Significação na Música Modernista de Villa-Lobos

A análise do Rudepoema, peça chave na produção de Villa-Lobos, demonstra sua técnica no uso de coleções simétricas no contexto pós-tonal, seguindo o caminho aberto por Debussy e Stravinsky. Suas conquistas podem ser comparadas às de Bartók na Hungria no que diz respeito à utilização do folclore brasileiro na linguagem modernista. Todavia a dissecação dos materiais revela um uso intensivo e inesperado de transformações motívicas e temáticas que se prestam à unificação da estrutura em blocos predominante. Deste processo de integração resulta uma forma híbrida de grande envergadura que sintetiza as funções formais da forma sonata com o caráter seccional dos conjuntos de variações. Este tropo de formas pode ser chamado de sonata-variações. Villa-Lobos também recupera a alternância de significações tópicas, característica do período clássico, para conseguir um processo de desenvolvimento da forma e, ao mesmo tempo, sugerir interpretações de exotismo do almejado público parisiense. Colorindo o discurso com tópicas contrastantes, Villa-Lobos nos permite correlacionar os materiais aos sentidos de “civilizado” e “selvagem”, uma oposição entre dois campos tópicos que representava um tema favorito das culturas francesa e brasileira daquele período

Morphological Description of Selected Pigeonpea (\u3ci\u3eCajanus cajan\u3c/i\u3e (L.) Millsp.) Lines

Seventeen pigeonpea pure line accessions selected for desirable forage traits and three commercial cultivars were described according to morphological characters. The following descriptors were used: growth habit, plant height, number of primary and secondary branches, stem color and thickness, leaf shape and hairiness, flower base and second color, pattern of flower streaks, flowering pattern, immature and mature pod color, pod form and hairiness, seed color pattern, base and second seed color, seed eye (region around hilum) color and seed shape and width. Each individual line and cultivar was satisfactorily distinguished from the others by the chosen characters

Water toxicity assessment in the Suape estuarine complex (PE-Brazil)

The Suape estuarine complex (PE, Brazil) is located close to an industrial port complex of Suape which has been responsible for altering the geomorphologic and hydrological conditions of the area. As the industrial port of Suape represents a possible source of pollution through the use and transport of chemical substances, the present research aimed to evaluate if the surface water of the estuarine complex in Suape shows chronic toxicity based on the embryo larval development of the sea urchin Lytechinus variegatus. Six sampling points were established between the estuaries of the rivers Massangana and Tatuoca. Samples of surface water from the area were collected on May, August, October and December of 2007. Chronic toxicity was observed in the six points and it varied depending on the month. The highest level of toxicity was on October when it was detected at all six points. The results showed that the water of the river Massangana was the most probable source of pollution in the area studied during this period

A Linguagem e a Formação do Sujeito Moral no Discurso Sobre a Desigualdade de Jean-Jacques Rousseau

O artigo discute a necessidade de se pensar a formação do sujeito moral sob a perspectiva da análise da linguagem e suas implicações nos estudos sobre a função da retórica na política no Segundo Discurso de Jean-Jacques Rousseau. A concepção do homem natural auxilia na noção do sujeito moral e a narrativa sobre o estado de natureza revela-nos a tríade linguagem, língua e retórica. Sucessões que integram a concepção do homem como indivíduo com consciência de si mesmo, o início da sociedade civil ligado à ideia da propriedade e o estabelecimento da sociedade civil com o discurso “sedutor” do rico que propõe o pacto político. De um ser disperso no estado de natureza, o homem se constitui como sujeito moral que supõe o uso da linguagem. O sujeito moral também utiliza a língua de modo retórico ao propor o pacto político. Há conflitos entre moralidade, política e retórica

Leaf, Pod and Whole Plant Tannin Contents in Pigeon Pea (\u3cem\u3eCajanus cajan\u3c/em\u3e (L.) Millsp)

Tannin content is an important characteristic of leguminous crops and it has been used as a selection criterion in pigeon-pea improvement programmes (Godoy et al., 1994). In south-eastern Brazil, pigeon pea is often consumed by bovines in the dry season (from April though October), after flowering occurs, and is recommended in some cases, specifically for that time of the year (Lourenço et al., 1994). Since tannin content is being used as a selection criterion and the animals in the dry season preferentially eat pods and leaves, an experiment was conducted to compare whole plant, leaf and pod tannin content

Use of deep multi-target prediction to identify learning styles

It is possible to classify students according to the manner they recognize, process, and store information. This classification should be considered when developing adaptive e-learning systems. It also creates a comprehension of the different styles students demonstrate while in the process of learning, which can help adaptive e-learning systems offer advice and instructions to students, teachers, administrators, and parents in order to optimize students’ learning processes. Moreover, e-learning systems using computational and statistical algorithms to analyze students’ learning may offer the opportunity to complement traditional learning evaluation methods with new ones based on analytical intelligence. In this work, we propose a method based on deep multi-target prediction algorithm using Felder–Silverman learning styles model to improve students’ learning evaluation using feature selection, learning styles models, and multiple target classification. As a result, we present a set of features and a model based on an artificial neural network to investigate the possibility of improving the accuracy of automatic learning styles identification. The obtained results show that learning styles allow adaptive e-learning systems to improve the learning processes of students105Applied machine learnin

Injury profile of a soccer player training center: An epidemiological study

oai:ojs2.mednext.zotarellifilhoscientificworks.com:article/1Objective: To carry out an epidemiological analysis characterizing the type and location of the injury, severity based on recovery time, game position, and injury for hours of exposure. Methods: Data collection was carried out in the sub 15, sub 17, and sub 20 categories and verified records made by the medical team of the club, which was trained to use the F-MARC form (a form of the medical research center of the International Football Federation - FIFA) at the beginning of the season. To perform the data analysis, the GraphPad Prism software was used. All variables were analyzed using the Kolmogorov-Smirnov test. Results: In relation to the 129 athletes monitored during the season, 62 athletes presented some injury during the season, presenting 42.2 injuries for every 1000 hours of play, the Sub 15 category was the one with the highest incidence of injury, followed by the Sub17 and U20. The average time of leave after injury was 3.65 ± 4.2 weeks, the Defenders were the ones with the highest injury rate. There were 27 articular injuries (43.54%), 25 muscle injuries (40.32%), 9 bone injuries (15.41%), and one pathological injury (1.61%), and the most affected regions were ankle and knee. Conclusion: It is concluded that the moment of the game is the moment when the greatest number of injuries occurs, having a greater incidence in the athletes of the category Sub 15, the Defenders suffered more injuries and the Lower Limbs were more affected, mainly by articular traumas
