La Théorie de la Disposition Rhétorique: Sa Formulation dans les Textes Classiques, sa Réapparition dans les Arts Poétiques de la Renaissance Française et son Influence sur la Composition des Sonnets pour Hélène (1578) de Pierre de Ronsard

Ferreira Gouveia, Paula 07 August 2013 (has links)
La rhétorique d’un recueil de pièces amoureuses relève de la rhétorique délibérative dans la mesure où l’amoureux tente de convaincre l’aimée d’agir dans le sens qu’il voudrait; de la rhétorique judiciaire lorsque l’amoureux s’adresse au lecteur et lui demande de juger de la situation où il se trouve; et de la rhétorique épidictique lorsqu’il y a louange ou blâme de l’aimée. De plus, étant donné que la poésie agit très directement sur le lecteur, le poète de la Renaissance a trouvé une forte correspondance entre les objectifs esthétiques de la poésie et les trois offices oratoires : plaire, émouvoir et instruire. La redécouverte des textes classiques d’Aristote, de Cicéron, et de Quintilien allait renforcer ces moments de croisement et permettre aux poètes de la Renaissance française de redéfinir leur rôle et celui de leur poésie. En principe, il s’agissait de libérer leurs œuvres poétiques de toutes les contraintes esthétiques et stylistiques valorisées au Moyen Age en composant leurs propres traités théoriques. En réalité, il s’agissait de renouveler l’esthétique poétique en préconisant l’importance de la pratique de l’imitation créatrice, c’est-à-dire, l’invention en lisant les anciens, et l’élocution en les imitant. L’imitation ne se limitait pourtant pas au niveau lexical. Elle s’accomplissait à l’intérieur d’une théorie rhétorique classique où la disposition, la seconde démarche consécutive de la rhétorique offrait à l’orateur des principes organisateurs qui s’appliquaient à la composition en vers. L’objet de cette thèse est donc de cerner une problématique que les poètes de la Renaissance ont dû confronter: comment structurer l’œuvre poétique. Dans un premier temps, en examinant la formulation de la théorie de la disposition classique et sa réapparition dans les arts poétiques de la Renaissance (1540-1560), cette étude établira que les règles de la rhétorique discursive qui régissent la composition et l’organisation du discours oratoire s’attachent facilement, au seizième siècle, à la composition poétique. Dans un deuxième temps, en analysant l’emplacement et l’enchaînement des pièces amoureuses dans les Sonnets pour Hélène (1578), ce travail de recherche examinera la façon dont ces mêmes principes organisateurs rhétoriques se font sentir dans le discours poétique amoureux.

La Belle au Bois Dormant (The Sleeping Beauty) Tchaikovsky-Pletnev and Stravinsky's Petrouchka: a study of piano transcriptions comprising performances and analyses.

Yang, Vicky (Chia-Yi) January 2005 (has links)
As the costs for mounting opera, ballet and orchestral concerts rise and as their audiences dwindle, piano transcriptions of works orchestrated for such concerts can be a viable way of disseminating the music more widely than if the music was presented only in its original form. With this in mind, it can be argued that piano transcriptions of music originally written for instrumental ensemble is still a viable form of musical expression, because the piano is still the most widely used medium for the performance of art music in the Western world. Transcriptions of instrumental and vocal music expand the listening audience for a composer's music while they also increase the repertoire of music for the piano for both amateurs and professionals. The CD recording has the aim of providing a reference on which to base an appreciation of Pletnev's work. As the orchestral score is quite well known, the differentiation created by Pletnev, and the quality of his work, can be immediately perceived by hearing the execution of his scores and being able to cross reference his reductions with the original score. Timing references for the piano score have been included to further facilitate this cross-referencing. This thesis comprises two parts: 1. A performance CD of Stravinsky's Petrouchka (1922 piano four-hand version) and Tchaikovsky's Sleeping Beauty (1999 solo piano transcription by Mikhail Pletnev). This accounts for 75% of the thesis. 2. An exegesis, analysing selected portions of the orchestral score of Tchaikovsky's The Sleeping Beauty Op.66 and Pletnev's piano transcription suite, prefaced by an overview of piano transcriptions from Liszt to Pletnev. This accounts for 25% of the thesis. The exegesis argues that, while seeking to recreate the colour and drama of Tchaikovsky's orchestral score within the context of a virtuosic piano solo, Pletnev has managed to transcribe Tchaikovsky's score faithfully with minimal alterations.

Automatic music transcription : an exploratory study

Matthaei, Peter E 04 1900 (has links)
Thesis (MScEng) -- University of Stellenbosch, 2004. / ENGLISH ABSTRACT: In a pioneering project for the University of Stellenbosch, and indeed South Africa, an automatic music transcription system was designed to explore the underlying theory, concepts and problematies of polyphonic music transcription. Automatic music transcription involves knowledge from the fields of acoustics, music theory, digital signal processing and information theory. The key concepts from these contributing fields as they relate to transcription systems are described in overview. A transcription system is then developed which includes components for FFT-based multipitch estimation, basic post-processing, estimation of the degree of polyphony, key determination, note duration quantisation and score output. The operation of the system is explained and tested at the hand of a synthetic polyphonic signal. The system produced usable transcriptions of real monophonic input signals to scores with standard notational symbols. The success of the system (as are the successes of all published polyphonic transcription systems) was limited for real polyphonic music signals. Nonetheless, the initial results are encouraging and indicate that the current implementation can serve as a platform for a more sophisticated and accurate system. / AFRIKAANSE OPSOMMING: In 'n baanbrekersprojek vir die Universiteit van Stellenbosch (en die breër Suid-Afrika) is 'n outomatiese musiek transkripsie stelselontwerp om die onderliggende teorie, konsepte en problematiek van polifoniese musiek transkripsie te ondersoek. Outomatiese musiek transkripsie kombineer kennis uit die navorsingsvelde van akoestiek, musiekteorie, syferseinverwerking en informasieteorie. Die sluitelkonsepte van elkeen van hierdie velde word kortliks weergegee soos dit van toepassing is op transkripsie stelsels. 'n Transkripsie stelsel met modules vir FFT-gebaseerde afskatting van polifoniese toonhoogtes, basiese naverwerking, afskatting van die graad van polifonie, bepaling van die sleutel, nootlengte kwantisering en bladmusiek notasie word aansluitend ontwikkel. Die werkswyse van die stelsel word aan hand van 'n sintetiese polifoniese sein verduidelik en getoets. Die stelsel lewer bruikbare transkripsies van enkelstemmige intreeseine na bladmusiek met standaard musieksimbole. Die sukses van die stelsel is beperk vir polifoniese musiek, soos ook die algemene geval is vir ander gepubliseerde meerstemmige transkripsie stelsels. Tog is die aanvanklike resultate belowend, met aanduidings dat die huidige implementering kan dien as 'n beginpunt vir die ontwikkeling van 'n meer gesofistikeerde en akkurate stelsel.

De biologiska barnens roll i familjehemsuppdraget : En kvalitativ studie utifrån socialtjänstens perspektiv / The biological children's role in the foster family care arrangement : A qualitative study through the perspective of the Social services

Persson, Nathalie, Karlsson, Saara January 2018 (has links)
The aim of the study was to gain knowledge about what role the foster carers’ biological children play in foster family care and also gain a deeper understanding of the biological children´s significance in a foster family care arrangement. The aim of the study has been conducted through the perspective of the Social services. The data collection consists of eight individual qualitative and semi-structured interviews with social workers who are currently working with foster families there biological children are living at home. The new childhood sociology and the concept of participation serve as the base of the theoretical framework and have been applied to the analysis of this study. The study shows that the respondents have a positive attitude towards the biological children´s presence in the foster families. They value the biological children´s function in the families as important and should thus not be forgotten. At the same time, there are no clear guidelines for how the social worker should work with foster carers’ biological children. The contact between the social worker and the biological children mostly goes through the children’s parents. The role of the biological children is not always clearly defined in the foster family care arrangement and their involvement can be perceived as insignificant. Furthermore the respondents terminates that no special support designed for biological children in foster families exists. Several respondents also reflect upon that they want to avoid burdening the biological children with responsibility that is not theirs to bear. The role of the biological children in the foster family care and their significance in the foster family care arrangement concludes therefore acknowledged by the social worker but not always recognized.

In this context, the present dissertation aims to investigate the relationship between the design of the classroom and the possi- ble interactions and experiences of its users, through the analysis of the spatial arrangements and their potentialities. The research involves bibliographical re- view, articulation of theoretical concepts, contextualization of space and place and an understanding of the classroom as an adaptive complex system. In this approach, three spatial arrangements of classrooms, identified by Scott-Webber (2009) as recurrent in educational institutions, are set up in rigid and fluid en- vironments, analyzed through personal space (SOMMER, 1973) and proxemic zones (HALL, 2006) theories. Therefore, it is possible to trace an activity profile and intention by using each arrangement, in order to promote the desired inte- ractions. It is discussed the rigidity of the projected space and its possibilities of adaptability to the needs of the users. In conclusion, the need to design spaces is more flexible and adaptable to contemporary demands. / O ambiente escolar formata um sistema de valores e discursos, no qual seus usuários são estimulados à aprendizagem. Neste sentido, esta dissertação tem como objetivo investigar a relação entre o design da sala de aula e as possíveis interações e experiências dos usuários, a partir da análise dos arranjos espaciais e suas potencialidades. A pesquisa envolve revisão bibliográfica, articulação dos conceitos teóricos, contextualização acerca de espaço e lugar e compreensão da sala de aula como sistema complexo adaptativo. Nesta abordagem, observa- se três arranjos espaciais de salas de aula, apontadas por Scott-Webber (2009) como recorrentes em instituições de ensino, que configuram ambientes rígidos e fluídos, analisados a partir das teorias de espaço pessoal (SOMMER, 1973) e zonas proxêmicas (HALL, 2006). Assim, é possível traçar um perfil de atividade e intenção com o uso de cada um dos arranjos, a fim de promover as interações desejadas. Discute-se a rigidez do espaço projetado e suas possibilidades de adaptabilidade às necessidades dos usuários. Conclui-se a necessidade de projetar espaços mais flexíveis e adaptáveis às demandas contemporâneas.

Identificação e análise dos impactos locais e regionais da introdução da produção de biodiesel no Estado do Piauí

Santos, Omar Inacio Benedetti January 2008 (has links)
A partir da constatação da emergência de uma nova configuração de um arranjo produtivo, voltado para a produção de biodiesel surgiram os questionamentos sobre os impactos locais desse processo. Buscou-se com essa pesquisa entender os mecanismos que ocorrem dentro dessa nova base produtiva e seus impactos locais sobre o nível de empregos, renda, saúde e educação. A partir desse problema o objetivo geral dessa dissertação foi desenvolver uma estrutura analítica para identificar e analisar os impactos na estrutura produtiva a partir da introdução da produção de combustível renovável, bem como identificar e analisar os principais impactos sobre as economias locais, em especial os impactos sobre a educação, saúde e emprego da região. A base teórica utilizada constitui-se de elementos da economia regional, cadeias produtivas, bioenergia, biomassa e biorefinaria, arranjos produtivos locais, cluster e inovação. A pesquisa de campo e secundária foram analisadas utilizando-se as estimativas das matrizes de insumo-produto e as metodologias de coeficiente locacional e shift-share. Essa pesquisa analisou a unidade de Floriano da empresa Brasil Ecodiesel, por sua importância relativa no cenário nacional e por estar em funcionamento desde 2005 e o projeto Fazenda Santa Clara em Canto do Buriti no mesmo estado. Pode-se dizer que uma nova dinâmica produtiva está ocorrendo no Piauí. As atividades agrícolas têm aumentado significativamente desde 2002. A empresa tem promovido um estímulo a produção de mamona e soja na região. Com relação aos impactos sociais pôde-se observar que houve melhoras nos índices de saúde, educação e habitação nos municípios que adotam a produção de mamona e soja. Na cidade de Floriano existem impactos indiretos a partir da instalação da Usina, e provavelmente o aumento com as despesas sociais seja efeito do aumento da arrecadação tributária indireta, dada à euforia que vive a cidade em torno da Usina. Existem alguns pontos que a empresa ainda necessita verificar que são sua atuação junto ao poder público municipal e instituições locais, e suas estratégias de produção de mamona, pôde-se perceber na pesquisa a falta de alinhamento de alguns produtores com as estratégias da empresa, e isso poderá vir a tornar-se um gargalo para o abastecimento das usinas. Essa integração entre grande empresa e produção familiar é uma forma socialmente apropriada de fazer negócio, em que o lucro vem associado a uma maior inserção social de seus colaboradores e parceiros, mas necessita de reciprocidade para dar certo. / The recent moves towards the insertion of biofuels in the energy matrix of a number of countries are opening new prospects for agricultural production and for agroindustrial chains. In Brazil, the Programa Nacional do Biodiesel (National Biodiesel Program) was created to establish the regulatory framework for the production, commercialization and consumption of Biodiesel. Besides the traditional production of biodiesel from soybean oil, the first productive bases using alternative oilbearing crops such as the castor bean, sunflower, palm and rapeseed are beginning to appear. The emergence of this new productive base raises new research issues: in what circumstances are the structuring, organization and implementation of these biodiesel productive chains taking place in Brazil? What are the effects of biodiesel production on local economies? Hence, the central objective of this study is the development and validation of an analytical structure capable of characterizing the biodiesel productive arrangements and identifying their economic and social impacts at the regions where they are installed. The analytical structure was constructed based on theories of regional and spatial economy: locational coefficient, Shift-Share, theories of industrial location. The biorefinery concept was used to identify the factors related to the management of biodiesel processing plants. A preliminary analysis identified that a biodiesel productive arrangement is emerging in the State of Piauí, Northeastern Brazil, with the purpose of stimulating regional development using alternative oilbearing crops. The firm Brasil Ecodiesel has established an industrial plant in the municipality of Floriano (Piauí) and a farm for the production of castor beans and other oil-bearing crops in the municipality of Canto do Buriti. Executives from the firm together with local agents and leaders (from local government, unions and commercial and industrial associations) were asked to respond to questionnaires related to the agricultural production destined to supply the processing plant. A survey of secondary data on the regional economy was also carried out. In order to govern and coordinate its productive chain Brasil Ecodiesel created an organizational structure responsible for the management of more than 630 contracts with local rural producers for the supply of oleaginous crops and regional offices to offer technical assistance and support to the producers. It can be seen that the local production of non-traditional oil-bearing crops (castor bean) has proven insufficient to meet the production needs of the firm. Due to this productive insufficiency, the supply of vegetable oil for the processing unit is ensured by obtaining soybean oil from locations far from the production plant (300- 500 km), thus increasing the production costs. The agricultural project in the town of Canto do Buriti has faced problems of both a cultural and productive nature. The Federal Government’s social assistance projects (e.g. Family pocket, basic basket,...) have the effect of reducing the commitment of the rural producers to the production performance objectives. Unfavorable edaphoclimatic conditions have also reduced the productivity levels of the local plantations. On the other hand, the impact of the new biodiesel production base is already perceptible in the town of Floriano. Calculations show an increase in the dynamism of the local retail market and civil construction. Preliminary findings reveal productive, organizational, managerial and governance related difficulties and challenges that need to be faced when establishing a new productive base in a location that up to that point lacks a productive tradition.
