Mapeamento geológico-geomorfológico na região de Quirinópolis-GO

Geological and geomorphological mapping is an important tool for the characterization of physical environment, thus enabling the planning and use of areas more efficiently. This work represents a geological- geomorphologic mapping on the scale of 1:20.000 in the rural area of Quirinópolis – GO town, where outcrop rocks of Paraná Sedimentary Basin, specifically the Bauru Group. Through the methodology of analysis of integrated elements of the physical environment, it was possible to delineate geological- geomorphological five units, which were characterized as lithology, topography, soil conditions, and operating processes, and the development of weathering profiles bring of great importance for planning of land use as occupation thus avoiding further degradation of the physical environment

Aplicações da teoria de Piaget ao ensino da matemática elementar

O presente trabalho tem por finalidade a aplicaçao de principios teóricos e experimentais de Jean Piaget ao ensino da matemática. Considerando-se as implicações educacionais da teoria, fizemos uma proposta de sistematizar uma metodologia de ensino que tem por fim a ativaçao das estruturas mentais pelo ensino da matemática. Este trabalho, em resumo, constitui uma sintese da teoria do desenvolvimento cognitivo de Piaget, e o relato de uma pesquisa experimental que teve por fim avaliar os efeitos de uma metodologia proposta para estruturas mentais na criança. Com esta finalidade, foram urilizados dois grupos de trabalho constituídos intencionalmente, um experimental e o outro de controle, ambos com 21 sujeitos, alunos da 2a série do 1o grau de escolas particulares da cidade de Goiainia (GO), de classe social média supeior e média inferior. Em ambos os grupos se realizou o pré-teste. A metodologia de ensino de fundamentação piagetiana foi utilizada para o ensino da matemática no grupo experimental, e no grupo de controle utilizou-se para o ensino da matemática uma metodologia considerada tradicional, durante o período de um semestre letivo. Após o trabalho, foi realizado o pós-teste em ambos os grupos e, um estudo comparativo dos resultados coletados permitiu verificar a eficiência da metodologia de ensino proposta e a fecundidade do ensino da matemática numa perspectiva piagetiana.

A educação musical sob a perspectiva da pedagogia histórico-crítica

This work, from of theorist perspective of Historical-Critical Pedagogy, presents the school Music Education like a social mediator environment between the practices, listening and musical everydaylife knowledges and the not-quotidian, which are constitution and accumulated, throughout the centuries of History, by the human societies. The purpose is to present a possible theorist foundation to define the importance of Music Education insert in the elementary school, like a subject destined to guarantee the whole children formation and the enrichment of their relations with the music. It is a theorist reflection that indicates the importance of observation of the quotidian and not-quotidian knowledges characteristics, moreover of complete importance of formal education and, in specific, of school Music Education on human development.

Agrupamentos Sonoros Plenos na Música de Simultaneidades Acústicas e Estruturais

The present article reflects about the concepts of linearity, space and acoustic complexity in the definition of sound grouping as a criticism to the linear concept of phraseology mainly when applied to the music of imitative texture or of complex simultaneities. It takes as examples works by Bach, Josquin des Prez and a fragment of "Lontano" by Ligeti, to study them in two distinct dimensions, simultaneous and interconnected: the acoustic dimension with its entire spectral complexity and the relational dimension which establishes the interaction among the figures in voices and texture layers with some kind of acoustic and structural simultaneity.

As junções de palavras no português brasileiro cantado: estudos para uma aplicação

This article is a reflection on the possibilities for the linking and or connection of words in Brazilian Portuguese lyric diction with the intention of contributing this as a tool for singers, singing and diction teachers working with BP. The proposal came from a study of the norms for the Brazilian Portuguese pronunciation 1938 and 1958 rules, which addressed the issue, in conjunction with the analysis of the current norms, published in 2007.

Genetic variation along time in a brazilian population of Aedes aegypti (Diptera : Culicidae), detected by changes in the esterase patterns

Aedes aegypti from the Brazilian cities of Sao Jose do Rio Preto (SJ) and Goiania (GO) were analyzed as to their esterase patterns and the results were compared with data obtained about 5 years before for SJ population. Esterase bands not detected in the previous study were now observed in mosquitoes from both SJ and GO populations, being the last considered a population resistant to insecticides. Other similarities between SJ and GO populations in this study, and some differences in comparison with the previous data on SJ were observed, involving, in addition to changes in band type, changes in frequency of mosquitoes expressing them and differential gene activation during development. As it is generally true for genetic features, changes in the esterase patterns are expected to be the result of factors such as selection by environmental conditions and genetic drift. In the present case, continuous use of insecticides aiming mosquito population size control in SJ by sanitary authorities could be involved in the observed changes. Changed esterases were classified as carboxylesterases and cholinesterases, which are enzymes already shown to take part in the development of resistance in several organisms. In addition, data obtained in the elapsed time by authorities responsible for the mosquito control has shown increasing insecticide resistance of SJ population mosquitoes parallel to increase in the total amount of esterases, reinforcing the mentioned possibility.

As escolas vocacionais e o terceiro ambiente de Hargreaves

The article refers to an official school experience which was developed in the Brazilian education in the 60's - the vocational schools. These schools enabled an artistic-musical learning experience which would be less technicist and autocratic, contributing in a satisfactory way to the future performing formation of the students. In addition to the historical report, the text refers to the British educator D. Hargreaves, who researched on the importance of the "third environment" in the musical learning and on the relationship existing between the internal and the external cognitive process. The text is part of the Master or Arts dissertation which is being carried out in the IA-UNESP (Institute of Arts - State of São Paulo University). The musical-theoretical foundations were provided by the ideas of D. Hargreaves, Sigurd Rascher, Yehudi Menuhi, among others, and by some researchers in the area of education. It is justified on the grounds of the present moment experienced by the musical teaching in face of the approval of Law n(o) 11.769/2008.

A Aplicabilidade da Pesquisa-ação na Educação Musical

Action-research is a model of scientific investigation which is not widely used in musical teaching, even considering its relevant application in the social sciences. David Tripp (2005) classifies it as a type of action-investigation which is used to define any process that follows a cycle where the practice is improved by the systematic oscillation from acting in the field of practice to investigating into it. With the approval by the Brazilian National Congress of Law 17,769, on August 18, 2008, and with the supplementary legislation, we understand that its use in the musical education would be beneficial. This justification has motivated the writing of this article, which approached the characteristics, functions and usefulness of the action-research. The consulted authors were, among others, D. Tripp, M. Thiollent, Maria A. Franco, G. Morceau, and Maria G. de Miranda. Two examples of Master's dissertations which adopted this type of research were mentioned.

A Música Coral dos Primórdios do Século XX aos Primórdios do Século XXI: a Composição para Coros e a Performance do Repertório Moderno/Contemporâne

This paper is a small part of my Doctoral dissertation which is a large study about the practice and sonority in various choral music styles. Focusing on the choral music from the beginning of the 20th century to the present day, and based upon a bibliographical review, this article describes the characteristics of the choral composition and reflects on the performance aspects of the performance of modern and contemporary choral repertoire such as vocal tone color, intonation and non-traditional vocal techniques.

A Educação Musical Brasileira e Três Modelos Explicativos de Mundo: em busca de significados

In this paper we study the main modalities of music education in Brazil and how they can be compared to different views worldwide. Recognition that modern practices in music education are inserted in contemporary knowledge paradigms shows their relevance to a changing world. According to this contemporary paradigm the practices included herein point to alternatives in the relationship between men and themselves, men and other men and men and the environment. They also encourage cooperation, the relationship among the arts, the conduction of actions ruled by the principles of ecology and the recovery of values lost or weakened.

Representação da morte feminina em L`Orfeo e Il Combattimento di Tancredi et Clorinda de Claudio Monteverdi

This paper refers to issues related to the harmonic language of Claudio Monteverdi, its harmonic procedures and resulting melodic movements, its use as a dramaturgical resource and its potential allegorical meanings, based on theories and classifications of modes of the sixteenth and seventeenth centuries. At first, it approaches the matter of the multiple names and meanings of the modes and their potential allegorical references according to different authors. Secondly, it presents the analysis of two examples from his operas that deal with the representation of the death of Euridice and Clorinda (Orfeo & Il combattimento de Tancredi e Clorinda, respectively), correlating their harmonic procedures to the corresponding dramaturgical situations.

O uso idiomático dos instrumentos de percussão brasileiros: principais sistemas notacionais para o pandeiro brasileiro

This article adresses the idiomatic use of Brazilian percussion instruments and their notation on compositions. It uses the Brazilian "pandeiro", which is the principal instrument of this category, to make a technical and comparative analysis of the two main notational systems for this instrument, which are the models developed by Luiz D'Anunciacao and the other by Carlos Stasi. It also includes suggestions to help the development of this notation. It gives a list and description of several method books that could help percussionists, composers and arrangers to deepen their knowledge of Brazilian percussion.
