A motivação no teatro musical sob a perspectiva da teoria da autodeterminação

Este estudo teve por objetivo geral investigar os processos motivacionais dos participantes de um grupo de Teatro Musical sob a perspectiva da Teoria da Autodeterminação - TAD (RYAN; DECI, 2004; REEVE, 2006). Os pesquisadores Edward Deci e Richard Ryan (1985, 2000, 2008a, 2008b) afirmam que todos os indivíduos possuem uma propensão inclinada à autorregulação. Por esse motivo, a TAD analisa as razões pelas quais os indivíduos podem se envolver ou evitar participar de determinadas atividades, e adota um conceito de internalização que é representada por um continuum de autodeterminação, evidenciando os diferentes tipos de motivação previstos na miniteoria da integração organísmica. Os tipos de motivação podem ser identificados de acordo com o nível de autodeterminação dos indivíduos, através da satisfação de três necessidades psicológicas básicas: a necessidade de autonomia, a necessidade de competência e a necessidade de pertencimento. Esta pesquisa tem uma abordagem qualitativa e escolheu-se o estudo de entrevistas como estratégia de investigação, utilizando a entrevista semiestruturada como principal técnica de coleta de dados. A pesquisa foi realizada com 12 participantes de um grupo de Teatro Musical de uma universidade do Estado Rio Grande do Norte, referida na pesquisa com o pseudônimo de Companhia Musicale. Os resultados apontam que a principal motivação dos alunos não era a intrínseca. Portanto, a motivação foi considerada complexa e multifacetada, pois os participantes passaram por internalização do comportamento dependendo das condições situacionais. As complexidades nas interações puderam promover a satisfação das necessidades psicológicas básicas dos integrantes que apresentaram maior internalização dos comportamentos autodeterminados. Assim, os integrantes com maior desempenho nas tarefas foram os que internalizaram a importância e o valor das atividades. O estudo busca contribuir para futuras pesquisas e colaborar no sentido de perceber a importância de investigar e promover a motivação de alunos, professores, diretores, regentes, coordenadores e participantes de grupos artísticos em geral, trazendo esclarecimentos que ressaltam as contribuições e a importância que a motivação tem sobre o ensino, a aprendizagem musical e o envolvimento de participantes de grupos artísticos em diferentes atividades.

Petrologia e geologia estrutural do plutão granítico Barcelona, província Borborema, NE do Brasil

The Dissertation aimed to advance the geological knowledge of the Barcelona Granitic Pluton (BGP). This body is located in the eastern portion of the Rio Grande do Norte Domain (RND), within the São José do Campestre subdomain (SJC), NE of the Borborema Province. The main goal was to understand the geological evolution of the rocks of the pluton and the tectonic setting of magma generation and its emplacement. The BGP has an assumed Ediacaran age and outcropping area of approximately 260 km2, being composed of three varied petrographic/textural facies: (a) porphyritic biotite monzogranite; (b) dykes and sheets of biotite microgranite; (c) dioritic to quartz-dioritic enclaves. The rocks of the BGP have the following structures: (i) a NE-SW and NW-SE directed magmatic fabric (Sγ), accompanied by a magmatic lineation (Lγ) with gentle dip to NE-SW and NW-SE. In the southern portion, there is the concentric pattern of this foliation with medium to high dip, and (ii) a solid state foliation, in part mylonitic (S3+), mainly on the eastern edge with slightly plunging to west. The integration of structural and gravity data permitted to interpret the emplacement of the BGP as controlled by the transcurrent shear zones systems Lajes Pintadas (LPSZ) and Sítio Novo (SNSZ), both of dextral strike-slip kinematics. Mineral chemistry data show that the amphibole form the porphyritic biotite monzogranite facies is hastingsite with moderate Mg / (Mg + Fe) ratios, indicating crystallization under moderate to high ƒO2 and cristallization pressure of around 5.0-6.0 kbar. The biotite tends to be slightly richer in annite molecule and plots in the transitional field from primary biotite to reequilibrated biotite. In discriminant diagrams of magmatic series, the biotite behave like those of subalkaline affinity, consistent with the potassium calc-alkaline / sub-alkaline geochemical affinity of the hosting rock. The opaque minerals are primarily magnetite, with some crystals martitized to hematite indicating relatively oxidizing conditions during magma evolution that originated the BGP. Zoning in plagioclase, K-feldspar and allanite crystals suggest fractional crystallization process. Lithogeochemical data suggest that the facies described for the BGP have similar magma source, usually plotting in the fields and trends of the subalkaline / high potassium calc-alkaline series.

Expressão geofísica-estrutural do lineamento transbrasiliano na porção central da Bacia do Parnaíba (Maranhão-Piauí)

The objective of this study was to characterize the structural-geophysical expression of the Transbrasiliano Lineament (TBL) in the east-central portion of the Parnaíba Basin. The TBL corresponds to a major Neoproterozoic NE-trending shear zone related to the Brasiliano orogenic cycle, with dextral strike-slip kinematics, underlying (but also laterally exposed in the NE and SW basin edges) the sedimentary section of the Parnaíba Basin. In this study, the interpretation of gravity and magnetic anomaly maps is consistent with the TBL kinematics, the signature of the geophysical anomalies corresponding to the high (plastic behaviour) and subsequent declining temperature (ductile to brittle behaviour) stages during Brasiliano and late Brasiliano times. The pattern of residual gravity anomalies is compatible with an S-C dextral pair shaping the geological bodies of an heterogeneous basement, such as slices of gneisses and granulites (positive anomalies), granitic and low-medium grade metasedimentary rocks (negative anomalies). Such anomalies curvilinear trends, ranging from NNE (interpreted as S surfaces) to NE (C surfaces), correspond to flattening surfaces (S), while the NE rectilinear trend must represent a C band. The narrower magnetic anomalies also display NNE to NE (S surfaces) trends and should correspond to similar (although narrower and more discontinuous) sources in the equivalent anomaly patterns. Pre-Silurian pull-apart style grabens may contribute to the NE negative gravimetric anomalies, although this interpretation demands control by seismic data analysis. On the other hand, the curvilinear anomalies associated to contractional trends are incompatible with their interpretation as pre-Silurian graben, in both maps. In the (reduced to the pole) magnetic anomalies map, most of these are again associated to low-temperature shear zones (C planes) and faults, juxtaposing distinct blocks in terms of magnetic properties, or eventually filled with basic bodies. It is also possible that some isolated magnetic anomalies correspond to igneous bodies of late-Brasiliano or Mesozoic age. The basement late discontinuities pattern can be interpreted in analogy to the Riedel fractures model, with steep dipping surfaces and a sub-horizontal movement section. This study also explored 2D gravity modeling controlled by the interpretation of a dip seismic line as regards to the Transbrasiliano Lineament. The rock section equivalent to the Jaibaras Group occupying a graben structure (as identified in the seismic line) corresponds to a discrete negative anomaly superimposed to a gravimetric high, once again indicating a stronger influence of older crystalline basement rocks as gravimetric sources, mainly reflecting the heterogeneities and anisotropies generated at high temperature conditions and their subsequent cooling along the TBL, during the Brasiliano cycle.

Caracterização estrutural e atividades farmacológicas do alginato obtido da alga Dictyopteris delicatula (J.V. Lamouroux., 1809) e seu derivado sulfatado

Marine algae are rich sources of various structural compounds which recently has been increasingly studied as a new source of bioactive substances. The alginate, as come as fucans, are considered the main acidic polysaccharides found in brown seaweed. This molecule consists a linear natural polysaccharide, non-sulfated, and presents monosaccharides: acid β-D-mannuronic (M) and α-L-guluronic acid (G); in a vast amount compositions and threads. Alginate has been widely applied in food and pharmaceutical industries because of its ability to retain water, forming films and gels as well as thickening, stabilizing and form emulsions. In this work we aimed to extract, structurally characterize, compare and analyze the possible pharmacological activities of native alginate molecule obtained from brown seaweed Dyctiopteris delicatula (DYN), and its chemically sulfated derivative (DYS). The alginate structure and composition molecule can be proven through chemical dosing, that showed low protein contamination and high sugar level, existence and separation of M and G blocks in the descending paper chromatography, infrared spectroscopy and nuclear magnetic resonance. Molecule sulfation was proven with sulphate dosage, resulting in 28.56% sulphate in molecule; electrophoresis, verify metachromasia with toluidine blue; and infrared spectroscopy, that showed a characteristic band at 1221cm-1 corresponding a sulfate group vibration. For the pharmacological activities the tests was: antioxidant activity, changes in cell function (MTT test) and anticoagulant test. In the antioxidant activity we observed that DYN showed better results in the kidnapping of hydroxyl radicals and ferric chelation compared to DYS, this had the best result in the total antioxidant capacity. Both showed similar activity in reducing power and the kidnapping radicals DPPH. In MTT test DYN and DYS had not proliferative and cytotoxic activity in fibroblast cells (3T3) and showed antiproliferative and cytotoxic activity in cancer cell lines HeLa and B16 melanoma. In anticoagulant assay DYN showed good activity in the intrinsic pathway of blood coagulation, and a small activity in the extrinsic pathway, in the other hand DYS showed only a very small activity in the extrinsic pathway, but cannot come to be regarded as an anticoagulant agent. From these results it can be concluded that the alginate was extracted and sulfated, revealing a potential compound to be used in the pharmaceutical industry as an anticoagulant agent, antioxidant and antitumor and the sulfation has not been conclusively important to performance in the tested pharmacological activities

O conceito de motivação em dizeres de professores de língua inglesa

This work aimed at analyzing the speeches constructed about motivation by English teachers who teach at public state schools in the interior of Minas Gerais. We aimed at delineating the concept of subject underlying the subjects’ notion of motivation and identifying the role that the English teacher attributes to himself and to the student when he/she enunciates on motivational issues, problematizing the possible consequences of these issues for some English teachers while working in public schools. In order to do so, our investigation made use of theoretical assumptions from Applied Linguistics and Discourse Analysis. The theoretical fundamentation deriving from Bakhtin Circle as well as from Michel Pecheux’s theoretical basis were also very relevant for this research. The intersection of these studying fields entails a theoretical construction that considers the voices of those who live the social practice (MOITA LOPES, 2006), which allows one to see the subjects through their heterogeneity, fluidity and fragmentation. Moreover, it generates knowledge about language in its political, ideological, social and historical aspects. AREDA (SERRANI, 1998) was used as a theoretical and methodological framework for data collection. In our analysis, we considered the voices and the conditions of production that constitute 5 English teachers and, from some selected speeches extracted from their discursive production, some notions as intra and interdiscourse, discursive resonance, discursive memory, among others, can be seen interwoven. We hypothesize that the production of meaning deriving from these English teachers comes from a cleavage between the interdiscursivity about motivation and their position in relation to the English language. Some of these teachers’ discursive inscriptions were delineated as they follow: i) the silenced motivation, in which the teachers come up with several voices, repeating what that has already been said about motivation through silence by excess; also, through an inscription in a process of anomy, the English teachers silence motivation, as they come up with other sayings, in an anomic order, denying their identification with their mother tongue and culture because of a desire to learn the foreign language and culture; ii) the motivation in/from/ by others that resounds, in the way the teachers speak, a relation of alterity on what, in/from desire of other relations (colleagues, students, teaching materials, media, etc.), other forms and alternatives are established as a guarantee of students’ motivation; the teachers are also inscripted in in-service practice training as a space of educational development, because they imagine that the experience of the in-service practice alone, which excludes the educational instruction from the Languages course in which they graduated/were graduating at, taught them how to motivate the students; iii) the motivation as a will of power/knowledge, which means there seems to be teachers’ inscription in the relationship between power and knowledge (Foucault, 1996), disconsidering the conflicts that constitute the English classroom to say that there is a control of the English teaching and learning process and, as a result, they also sustain that they hold control over how to motivate; furthermore, the presence of a resonant voice, whose effect is given by an inscription on the (illusion of) completeness can be seen, because the English teachers believe that while motivating their students, this motivation will provide them with all the missing elements, which would mean that when they motivate students, they would be able to fulfill all the gaps in their learning process.

Restrição externa, dependência estrutural de commodities primárias e o investimento direto externo no Brasil

As the beginning of the discussion about the reprimarization process of the Brazilian exportations, or about a deindustrialization process of the country foreign sales, this study purpose that the discussion, actually, should be about the existence of the commodities structural dependence as a way to face the foreign restrictions. Therefore the intention is to show that, historically, the way that the Brazilian economy has crossed for its development depends of the foreign capital, mainly in its way of Foreign Direct Investment (FDI), and in the balance generated by the primary products, which make us try to understand the impact of this capital for the equilibrium of the Brazilian Payment Balance and also for the economy. These points were discussed not only based on the Brazilian classic writers as Francisco Oliveira, Caio Prado Jr. and Celso Furtado, but also using the newest studies which contributes to point the causes and consequences of the external capital dependence in the actual scenario. The conclusions acquired in the end of the study, indicates the fact that the Brazilian specialization in products of low aggregated value is not recent. Brazil is, historically, a competitive country in primary products. At the same time, the country importation always was a pressure factor of the National Payments Balance, being composed by products with more aggregated value. According to some authors, this characteristic of the Brazilian Economy will be surpassed with the economic opening process, which will attract external capital making possible the modernization of the Brazilian productive sector. Therefore, we can claim that the FDI, in the way it has been inserted in the country, does not offer the opportunity to get out of the commodities dependence, as generators of the payment balances, because the country international competitive standard didn t get any important changes, keeping itself out of the step related to the global standard which has been intensified in products with more aggregated value. The changes in the national insertion standard directed to more technological products is really important to surpass the historical scenario of commodities dependence, making the country less vulnerable to external crisis.

Relação Entre Motivação e Desempenho Escolar em Alunos do 1º Ciclo

O presente estudo teve como objectivo analisar a existência de uma possível relação entre motivação (intrínseca ou extrínseca) e o desempenho escolar em alunos do 1º ciclo que frequentam o 4º ano. A amostra foi constituída por 62 alunos, com idades compreendidas entre os 9 e 10 anos, 15 que frequentavam a Escola Básica do 1º Ciclo de Brancas e 47 a Escola Básica da Batalha (24 alunos da Turma A e 23 da Turma B). Considerando a possível existência de variáveis sociodemográficas associadas ao desempenho, no processo de recolha de dados foi aplicado um questionário sóciodemográfico, que pela sua potencial natureza descritiva, interpretativa e reflexiva, constituiu uma importante ferramenta na análise e avaliação dos resultados obtidos. Com o objectivo de avaliar a motivação (intrínseca e extrínseca) foi administrada uma escala de motivação escolar, aferida para a população portuguesa contendo 18 questões. Cada uma destas questões contém 4 possibilidades de resposta (duas referentes à motivação intrínseca e outras duas referentes à motivação extrínseca). Quanto ao desempenho escolar, este foi avaliado através das notas que os alunos obtiveram no final do ano lectivo e que foram facultadas pelas professoras dos mesmos. A análise dos resultados evidenciou que existe uma relação entre a motivação e o desempenho escolar, concluindo-se que os alunos intrinsecamente motivados apresentam melhor desempenho do que os alunos extrinsecamente motivados. Consideramos deste modo, que a implementação de estratégias na sala de aula que promovam a motivação intrÍnseca será mais benéfico para o sucesso escolar dos alunos. / The objective of this study, is to analyze the possible relation between intrinsic and extrinsic motivation and the educational achievement in students in the fourth grade of grade school. The sample was composed by 62 students, with a ages between 9 and 10 years of age. 15 students of this sample attended the grade school of Brancas, 47 attended the grade school of Batalha ( 24 of the students are from class A and 23 are from class B). Considering a possible existence of sociodemographic variables related to achievement, in the process of data collecting, a sociodemographic questionnaire was used, considering its great potential to describe, interpret analyze and evaluate the results obtained. To evaluate intrinsic and extrinsic motivation, a scale of school motivation adapted for Portuguese population with eighteen questions was applied. Each of these questions has 4 possibilities of response (two referring to intrinsic motivation and two referring to extrinsic motivation). In what concerns to school achievement, this was evaluated trough school grades obtained at the end of the school year given by the teachers. The analyses of the results demonstrated that there are differences between motivation and school achievement, concluding that the students with intrinsic motivation present better achievement then the students with extrinsic motivation. The implementation of strategies in the classroom, will promote intrinsic motivation and bring more success to students.

Motivação para a Mudança em Doentes Alcoólicos

Este estudo tem como objectivo identificar os estádios de motivação em que se encontram os indivíduos com problemas relacionados com o álcool, quando se encontram internados para tratamento. Pretende-se ainda verificar se existe correlação entre o grau de dependência e o estádio em que se encontra o indivíduo. A população em estudo é composta por 40 indivíduos do sexo masculino, encontrando-se todos na primeira semana de tratamento. Para analisar a amostra, os instrumentos utilizados foram um questionário sóciodemográfico, o questionário AUDIT que avalia o grau de dependência alcoólica, e os questionários RCQ e o EEM que avalia os estádios de motivação para a mudança. Este é um estudo quantitativo descritivo correlacional. Os resultados obtidos foram de que os indivíduos se encontravam no estádio de contemplação e que o grau dependência influenciava o estádio de mudança dos mesmos. / The main goal of this study is to identify the motivation stage in which the individuals with alcohol related problems are, while they were hospitalized. We also aim to verify if there is a correlation between the dependency level and the individual’s stage. Our sample has 40 male individuals that were in the first week of treatment. In order to analyze this sample, we have used a socio-demographic questionnaire, the AUDIT, as a tool that assesses the level of alcohol dependency, the RCQ e o EEM that evaluates the motivation stages to change. This is a quantitative descriptive correlational study. As results were obtained that individuals were in the contemplation stage and the dependence level influenced the stage of change of the individuals.
