Composer-Computer-Interpreter: a three-way collaborative process to the creation of two new works for multipercussion
No full textLast decades we see a redefinition in the way of interaction between the performer and the composer, an interaction that led to the discovery of new paths of creative collaboration between parts. This article is a study of this relationship as presented in the works “Solo I” for multipercussion and “Solo for Two”, a duo for two multipercussion sets by Dimitris Andrikopoulos. We address, firstly, the collaborative process between the composer and the interpreters from the early stages of the creation of the works up to the moment of performance and recording of the pieces and how this process and collaborative attitude influenced basic parameters of the composition. Further, we address issues related to the generation of compositional material through algorithmic processes, material that was used in the creation of the pieces, itself a type of collaboration between the composer and the computer inside a Computer Assisted Composition environment.publishe
Becoming White?
No full textIn this autobiographical essay, I explore two parallel processes that are somehow interconnected: the first is the shift in my own understanding of race throughout my life, from my formative years in Greece until my recent years in the Netherlands, where I began an academic career as an anthropologist. The second is my own racialization as ‘white’ since I moved to the Netherlands and became an academic. After I outline what were the relevant categories of difference in the small city of Greece where I grew up., I ask how appropriate it is to apply the category of ‘white’ to migrant scholars whose pathway to academia started in contexts in which whiteness had different meanings or was less significant as a marker of privilege
Características do romantismo na atualidade
No full textA minha dissertação têm como objetivo investigar e determinar as características que definem o movimento romântico: os movimentos antecedentes; o contexto urbano, rural, político, social da época; o indivíduo romântico: um ser puramente emocional e expressivo; o artista como ser da natureza; as características do movimento pós e neo-romântico; as características do romantismo inserido na atualidade; e análise do meu reportório composicional.
Neste sentido, pretendo dar a entender como é que consigo adotar uma escrita composicional atual inspirada numa estética romântica e pretendo dar a entender a importância que o romantismo deve ter na nossa sociedade para que consigamos formar uma comunidade mais sensível, unida, justa, desenvolvida e compreensível.My dissertation aims to investigate and determine the characteristics that define the romantic movement: the antecedent movements; the urban, rural, political, social context of the time; the romantic individual: a purely emotional and expressive being; the artist as a being of nature; the characteristics of the post and neo-romantic
movement; the characteristics of romanticism inserted in the present time; and analysis of my compositional repertoire.
In this sense, I intend to understand how I can adopt a current compositional writing inspired by a romantic aesthetic and I intend to understand the importance that romanticism must have in our society so that we can form a more sensitive, united, just, developed and understandable community
Viagem pelo repertório didático da viola d’arco
No full textO principal objetivo e foco deste relatório de estágio de prática de ensino supervisionado e projeto de investigação, prende-se com a prática da autora do mesmo como docente ao longo de um ano letivo consecutivo, na Academia de Música de Costa Cabral e, posteriormente na Academia de Música de Vilar do Paraíso. Tal prática levou a autora à elaboração de um documento reflexivo acerca do estágio realizado, onde todas as experiências e aprendizagens advêm de tal processo.
Relativamente ao projeto de investigação, este surgiu, pois, a autora deste trabalho sentiu a necessidade de uma investigação sobre os métodos usados pelos diversos docentes da zona norte do país e utilizados em vários níveis de estudo, criando assim uma fotografia deste momento temporal. Finalmente, e na ausência de uma aproximação educativa relacionada com a música contemporânea, a autora pediu algumas obras didáticas a três compositores Portugueses para serem utilizadas, explorando assim alguns novos caminhos no ensino da Viola d´ Arco.The main objective and focus of this report and of this research project, is related to the authors teaching practise for the academic year 2017-2018 at the Academia de Música de Costa Cabral as well as the Academia de Música de Vilar do Paraíso. The above mentioned practise, led the author to the creation of a reflective document related to teaching methodologies as well as the experiences and learning processes resulted out of these practises.
Related to the research project, the author of this work felt the necessity of a research in the teaching methods used by different teachers in the northern part of the country and currently being used in different levels of Viola study, creating a photography of this moment in time.
Finally, and in the absence of a teachinmg approach through contemporary music, the author commisioned three didactic works to three Portuguese composers in order them to be used in classes, exploring in this way some new approaches to the teaching of Viola
Composição para sopros assistida por computador
No full textA dissertação aqui apresentada centra-se na composição para sopros, no contexto de ensembles com as mais diversas dimensões. O meu trabalho na área segue a aplicação dos conceitos da Composição Assistida por Computador (CAC - Computer Aided Composition) na exploração de uma atitude espectral. O seu desenvolvimento assenta em pesquisas efetuadas em artigos, livros e outras dissertações como reflexão própria, assim como em conhecimentos adquiridos no decorrer da licenciatura; quer através das análises de obras, quer através da aplicação dos conceitos teóricos em composições espectralistas. Dadas as delimitações temporais da composição assistida por computador, bem como o desenvolvimento de técnicas espectrais na composição, o meu estudo, acerca da composição para sopros centra-se a partir da segunda metade do séc. XX.
Na procura de uma atitude espectral, darei especial importância ao estudo do timbre e do tempo. Sob o ponto de vista tímbrico, o objecto do estudo é o som de origem acústica, no sentido dos sons recolhidos de instrumentos musicais ou sons de fontes extra musicais, como por exemplo os sons da Natureza e o ruído. Na abordagem ao tempo, interessar-me especialmente as estruturas métricas denominadas árvores rítmicas, conforme apresentadas por William Tecumseh Sherman Fitch no artigo Rhythmic cognition in humans and animals: distinguishing meter and pulse perception, (Fitch, 2013), pois afiguram-se como sendo o que mais se aproxima da abordagem composicional que pretendo estudar e aplicar.
Neste projeto, o computador é uma plataforma importante pela utilização de programas de análise e edição de som como Spear, bem como os programas de assistência na CAC, o PWGL. O Computador assume assim um papel essencial no processo composicional.The dissertation presented here focuses on the composition to blows in the context of ensembles with the most diverse dimensions. My work in the area following the application of the concepts of composition assisted by computer (CAC - Computer Aided Composition) in the generation of a spectral attitude. Its development is based on surveys conducted in articles, books and other dissertations as own reflection, as well as knowledge acquired during the degree; either through analysis of works, or through the application of theoretical concepts of spectral compositions. Given temporal boundaries of computer-assisted composition, as well as the development of spectral techniques in composition, my study about the composition blows focuses from the second half of the century. XX.
In looking for a spectral attitude, I give special importance to the study of timbre and time.
Under the timbre point of view, the object of the study is the acoustic sound source in the direction of the collected sound of musical instruments or sounds of musical additional sources, such as nature sounds and noise. In the approach to time, especially interest me metric structures called rhythmic trees, as presented by William Tecumseh Sherman Fitch in Article Rhythmic cognition in humans and animals: distinguishing meter and pulse perception, (Fitch, 2013), because it seem to be which is closest to the compositional approach I intend to study and apply.
In this project, the computer is an important platform for the use of analysis programs and sound editing as Spear and assistance programs in the CAC, the PWGL. The computer thus plays an essential role in the compositional process
Corporate hedging, firm risk, value, and performance : evidence from UK firms
No full textThis study investigates the corporate hedging decisions associated with firm value, performance, and risk. A number of theories in risk management literature suggest that, in market imperfections, the use of derivative instruments for hedging purposes increases firm value overall by mitigating agency costs and a firm’s returns variability. Using a sample of UK nonfinancial listed firms during the period 2005-2012, we examine: (i) the effect of investment inefficiency on corporate hedging decisions; (ii) the impact of the use of foreign currency (FX), interest rate (IR), and commodity (CM) derivatives on firm value and performance; and (iii) the association between the corporate risk hedging and both stock returns volatility and the cost of equity capital implied in stock prices. We document new evidence regarding the effect of investment inefficiencies on hedging decisions. We find that hedging is strongly and positively associated with underinvestment or overinvestment, which confirms Morellec and Smith’s (Review of Finance, 2007, 11, 1-23) theoretical analysis. We find strong evidence that derivative usage has differential firm valuation and performance effects depending on the financial risk type, contract type, and time of hedging strategies. Consistently, we find that FX risk hedging positively influences firm value and performance, while there is no significant result of IR risk hedging associated with the firm value creation which means that IR derivatives can be used for hedging or speculative purposes. Not surprisingly, the results show that forwards and swaps for FX risk hedge are positively and significantly associated with firm value over the time period, while firms associated with financial constraints are highly motivated to use options contracts. Finally, our results show that the stock returns volatility, on average, is lower when firms exercising hedging decisions overall, where a decline in the implied cost of equity is substantial. Our empirical results confirm these predictions and robust after employing various methods (e.g. special regressor, instrumental variables (IV-GMM), treatment effects, propensity score matching (PSM), and difference-in-differences (DiD)) to address potential endogeneity issues. However, our findings indicate that, consistent with the notion of the positive theory of financial risk management, the corporate hedging has economic values to derivative users
A Generalization of Arrow’s Lemma on Extending a Binary Relation
No full textBy examining whether the individualistic assumptions used in social choice could be used in the aggregation of individual preferences, Arrow proved a key lemma that generalizes the famous Szpilrajn’s extension theorem and used it to demonstrate the impossibility theorem. In this paper, I provide a characterization of Arrow’s result for the case in which the binary relations I extend are not necessarily transitive and are defined on abelian groups. I also give a characterization of the existence of a realizer of a binary relation defined on an abelian group. These results also generalize the well-known extension theorems of Szpilrajn, Dushnik-Miller, and Fuchs
