De la chanson à l'air de cour : édition et mutations du répertoire profane en France (1555-1624) / From the Song to the "air de cour" : publishing and mutations of the secular repertoire in France (1555-1624)

Khattabi, Nahéma 06 December 2014 (has links)
Le répertoire profane imprimé dans la seconde moitié du XVIe siècle et au début du XVIIe siècle est riche de multiples objets musicaux, si l'on en croit tout du moins la diversité lexicale des titres de volumes publiés en France. Alors que dans la première moitié du XVIe siècle, le terme « chanson » est le titre incontournable placé en tête de volume par les imprimeurs de musique, à partir des années 1550 fleurissent de nouvelles appellations comme « chanson en forme de voix de ville », « ode », « chanson en façon d'air », « air de cour », « air », « dialogue », « sonnet », « Amours », « poésie », « quatrain », « chansonnette mesurée », « villanelle », « mascarade », « ballet », « récit » ou « vers mesurez ». Ces multiples dénominations ne renvoient toutefois pas nécessairement à des objets musicaux différents : pour exemple, au XVIe siècle, une même pièce peut être indifféremment appelée « chanson » et « ode » selon les publications. Cette observation amène à supposer que ces termes ne désignent pas des catégories s'excluant les unes les autres. Ces différentes rubriques sont au contraire poreuses, et leurs contours paraissent parfois vagues aux yeux du chercheur, notamment parce que les théoriciens de la musique, en particulier à la Renaissance, ne définissent pas les dénominations que l'on trouve dans les imprimés. Pour cette raison, l'enjeu de ce travail consiste à observer et à comprendre quelles sont les réalités éditoriales et musicales que recoupent les classifications et les termes utilisés dans les livres. Ce faisant, il s'agit de mettre en lumière le rôle clef de l'imprimeur de musique dans la fabrication matérielle du livre, et de se demander ainsi quelle est la part qu'il prend dans les mutations musicales. / The french repertory printed during the second half of the sixteenth century and at the beginning of the seventeenth century is rich of many musical objects. If in the first half of the sixteenth century, the term « chanson » is the only title used in the editions, other denominations appear from 1552 as « chanson en forme de voix de ville », « ode », « chanson en façon d'air », « air de cour », « air », « dialogue », « sonnet », « Amours », « poésie », « quatrain », « chansonnette mesurée », « villanelle », « mascarade », « ballet », « récit » or « vers mesurez ». These denominations don't designate necessarly differents musical objects : for exemple, during the sixteenth century a same work could sometime be named « chanson » and « ode ». This observation tends to suppose that these terms don't designate indepedant categories. On the contrary, these headings are porous, and their outlines seems sometime vague, in particular because the renaissance music theorists don't define the terms used in the prints. For this reason, the goal of this dissertation consist to observe and understand what are the editorial and musical realities which tally with the classifications and the terms used in the collections. Thus, we would like to highlight the role of the music printer in the making of the book, and to wonder what is the part he takes in the musical mutations.

Condições de acesso e permanência das mulheres no movimento sindical

Santos, Verônica de Barros 27 February 2018 (has links)
This study is an analysis of the conditions of access and permanence of women in the trade union movement. The issue is framed in the discussions on the political participation of women and the cut is the trade union movement. Considering that the political and trade union fields have traditionally been dominated by men, and considering the increasing participation of women, we aim to investigate the constraints of their insertion in these spaces. To that end, we selected as a reality to be observed the category of Technical-Administrative in Education - TAE, formed by professionals that make up the administrative sphere of Brazilian public higher education institutions. The representation tables, previously composed predominantly by men, gradually changed with the presence of women. Because of these changes, we propose to think the mechanisms that justify them and frame the analysis from two perspectives. In the first, we place the category of TAE in front of the institution that represents it nationally, the Federation of Trade Unions of Technical-Administrative Workers in Public Higher Education Institutions of Brazil - FASUBRA Sindical. In this regard, we analyze the composition of the national leadership and the directorates/coordinations of the affiliated unions, taking into account the percentages and places occupied by men and women. In the second, we selected one of the affiliated unions, the Syndicate of Technical-Administrative Workers in Education of the Federal University of Sergipe - SINTUFS. We seek to understand the conditions of access and permanence of women with the focus on the relational aspects around the engagement of the militants. The study was guided by the sociology of militancy and the gender approach, and the main concepts and notions employed were: trajectories, careers, sexual division of labor, militant engagement and social bonds. We use different methodological strategies, such as document consultation, questionnaire application, participant observation and biographical interview. We have identified the presence of many women in the directorates/coordinations of FASUBRA's basic institutions. However, differences were also observed in the number of places occupied by men and women. The social ties and some experiences found in women's itineraries have emerged as a mechanism to explain their entry and stay in union leadership. Among the types of links, the personalities were more relevant, and educational experiences were the most significant resources for engagement. We find that, in general, the increase of women in the trade union movement is associated with their participation in the labor market and the cultural and social transformations that affect the role of women in society. The unionists justified that the awareness of the need to occupy political spaces by women and, especially, the commitment to the working class were the reasons for their militant engagement. / Este estudo é uma análise das condições de acesso e permanência das mulheres no movimento sindical. A temática está enquadrada nas discussões sobre a participação política das mulheres e o recorte é o movimento sindical. Considerando que os campos político e sindical foram tradicionalmente dominados pelos homens, e considerando a crescente participação de mulheres, objetivamos investigar os condicionantes da inserção delas nesses espaços. Para tanto, selecionamos como realidade a ser observada a categoria dos Técnico-Administrativos em Educação - TAE, formada pelos profissionais que compõem a esfera administrativa das instituições de ensino superior público brasileiro. Os quadros de representação, antes compostos predominantemente por homens, aos poucos sofreram modificações com a presença das mulheres. Em razão dessas mudanças, propomos pensar os mecanismos que as justificam e enquadramos a análise sob duas perspectivas. Na primeira, situamos a categoria dos TAE frente à instituição que a representa nacionalmente, a Federação de Sindicatos de Trabalhadores Técnico-Administrativos em Instituições de Ensino Superior Públicas do Brasil - FASUBRA Sindical. Nesse aspecto, analisamos a composição da direção nacional e das direções/coordenações dos sindicatos filiados, levando em consideração os percentuais e os lugares ocupados por homens e mulheres. Na segunda, selecionamos um dos sindicatos filiados, o Sindicato dos Trabalhadores Técnico-Administrativos em Educação da Universidade Federal de Sergipe – SINTUFS. Buscamos apreender as condições de acesso e permanência das mulheres com o enfoque nos aspectos relacionais em torno do engajamento das militantes. O estudo foi norteado a partir da sociologia da militância e da abordagem de gênero, e os principais conceitos e as noções empregados foram: trajetórias, carreiras, divisão sexual do trabalho, engajamento militante e vínculos sociais. Utilizamos diferentes estratégias metodológicas, tais como, a consulta a documentos, a aplicação de questionário, a observação participante e a entrevista biográfica. Identificamos a presença de muitas mulheres nas direções/coordenações das instituições de base da FASUBRA. Contudo, também foi observado diferenças em relação aos lugares ocupados por homens e por mulheres. Os vínculos sociais e algumas experiências encontradas nos itinerários das mulheres emergiram como mecanismo que servem para explicar a entrada e a permanência delas na liderança sindical. Entre os tipos de vínculos, os pessoais tiveram maior relevância, e as experiências educacionais foram os recursos mais significativos para o engajamento. Constatamos que, de modo geral, o aumento de mulheres no movimento sindical está associado à participação delas no mercado de trabalho e às transformações culturais e sociais que envolvem o papel da mulher na sociedade. As sindicalistas justificaram que, a conscientização da necessidade de ocupação dos espaços políticos pelas mulheres e, principalmente, o compromisso com a classe trabalhadora foram os motivos do seu engajamento militante. / São Cristóvão, SE

No. of bitstreams: 1 Tese_Jorge_Ferreira.pdf: 520002 bytes, checksum: 2bd34704d262bc96ce3fdcb3168e5c2e (MD5) Previous issue date: 2009-03-27 / The objective was to evaluate the effects of the year (sample size, genealogy and data structure), mother-offspring link proportion (mother-offspring pairs, both with weaning weights), inclusion (M2) or not (M1) of the genetic direct-maternal covariance in the model, the direct-maternal correlation (C) magnitude and the direct and maternal genetic variance ratio (R) on the (co)variance estimates on weaning weight of beef cattle. The effects of the correlation (C) and variance ratio (R) were significant on the estimate of direct genetic variance ( ) (P<0,05, P<0,001, respectively), maternal genetic variance ( ) (P<0,001) and direct-maternal genetic covariance ( ) (P<0,001). The year influenced significantly (P<0,01) the estimates of and was not significant on and . The effect of the mother-offspring link proportion (E) was significant (P<0,0001) on the estimate of , , , and , being not significant on . In the model with zero direct-maternal covariance, and were underestimated when the direct-maternal correlation was negative, and overestimated when it was positive. Accurate and precise estimates of genetic variances and covariances of traits under maternal effect deserve detailed study and intensified, since these estimates may be influenced by the nature and composition of data, direct-maternal genetic correlation model used and applied. However, these facts may contribute to mistaken conclusions that are not referenced. These results are indicatives of the potential reliability and accuracy of the estimates on real data, although it is known that its magnitudes may differ, due to additional bias, like inherent errors of data gathering process and information flow from the herds. / Objetivou-se avaliar os efeitos do ano (tamanho amostral, genealogia e estrutura dos dados), da proporção de elos mãe-progênie (pares mãe-filho ambos com registro), da inclusão (M2) ou não (M1) da covariância genética direta-maternal no modelo, da magnitude da correlação genética direta-maternal (C) e da razão entre as variâncias genéticas direta e maternal (R) sobre as estimativas para peso à desmama em bovinos de corte. Os efeitos da correlação (C) e razão entre variâncias (R) resultaram significativos sobre as estimativas da variância genética direta (P<0,05, P<0,001, respectivamente), maternal ( ) (P<0,001) e da covariância genética direta-maternal ( ) (P<0,001). O ano influenciou significativamente (P<0,01) as estimativas de , e não foi significativo sobre e . O efeito da proporção de elos mãe-progênie (E) foi significativo (P<0,0001) sobre as estimativas de , , , e , não sendo significativo sobre . No modelo com covariância direta-maternal zerada e foram subestimadas quando a correlação genética direta-maternal foi negativa, e superestimadas quando a mesma foi positiva. Estimativas acuradas e precisas das (co)variâncias de características sob efeito maternal merecem estudos intensificados e detalhados, uma vez que, essas estimativas podem ser influenciadas pela natureza e composição dos dados, correlação genética direta-maternal e modelo aplicado. Estes resultados provem indicativos sobre a confiabilidade e precisão potenciais das estimativas sobre dados reais, embora se saiba que suas magnitudes possam diferir, devido a causas adicionais de viés, como erros vinculados ao processo de coleta e fluxo das informações dos rebanhos

Modélisation du bruit de phase et de la gigue d'une PLL, pour les liens séries haut débit / PLL Phase Noise & Jitter Modeling, for High Speed Serial Links

Bidaj, Klodjan 30 November 2016 (has links)
La vitesse des liens séries haut débit (USB, SATA, PCI-express, etc.) a atteint les multi-gigabits par seconde, et continue à augmenter. Deux des principaux paramètres électriques utilisés pour caractériser les performances des SerDes sont la gigue transmis à un niveau de taux d’erreur donné et la capacité du récepteur à suivre la gigue à un taux d’erreur donné.Modéliser le bruit de phase des différents components du SerDes, et extraire la gigue temporelle pour la décomposer, aideraient les ingénieurs en conception de circuits à atteindre les meilleurs résultats pour les futures versions des SerDes. Générer des patterns de gigue synthétiques de bruits blancs ou colorés permettrait de mieux analyser les effets de la gigue dans le système pendant la phase de vérification.La boucle d’asservissement de phase est un des contributeurs de la gigue d’horloge aléatoire et déterministe à l’intérieur du système. Cette thèse présente une méthode pour modéliser la boucle d’asservissement de phase avec injection du bruit de phase et estimation de la gigue temporelle. Un modèle dans le domaine temporel en incluant les effets de non-linéarité de la boucle a été créé pour estimer cette gigue. Une nouvelle méthode pour générer des patterns synthétiques de gigue avec une distribution Gaussienne à partir de profils de bruit de phase coloré a été proposée.Les standards spécifient des budgets séparés de gigue aléatoire et déterministe. Pour décomposer la gigue de la sortie de la boucle d’asservissement de phase (ou la gigue généré par la méthode présentée), une nouvelle technique pour analyser et décomposer la gigue a été proposée. Les résultats de modélisation corrèlent bien avec les mesures et cette technique aidera les ingénieurs de conception à identifier et quantifier proprement les sources de la gigue ainsi que leurs impacts dans les systèmes SerDes.Nous avons développé une méthode, pour spécifier la boucle d’asservissement de phase en termes de bruit de phase. Cette méthode est applicable à tout standard (USB, SATA, PCIe, …) et définit les profils de bruits de4phases pour les différentes parties de la boucle d’asservissement de phase, pour s’assurer que les requis des standards sont satisfaits en termes de gigue. Ces modèles nous ont également permis de générer les spécifications de la PLL, pour des standards différents. / Bit rates of high speed serial links (USB, SATA, PCI-express, etc.) have reached the multi-gigabits per second, and continue to increase. Two of the major electrical parameters used to characterize SerDes Integrated Circuit performance are the transmitted jitter at a given bit error rate (BER) and the receiver capacity to track jitter at a given BER.Modeling the phase noise of the different SerDes components, extracting the time jitter and decomposing it, would help designers to achieve desired Figure of Merit (FoM) for future SerDes versions. Generating white and colored noise synthetic jitter patterns would allow to better analyze the effect of jitter in a system for design verification.The phase locked loop (PLL) is one of the contributors of clock random and periodic jitter inside the system. This thesis presents a method for modeling the PLL with phase noise injection and estimating the time domain jitter. A time domain model including PLL loop nonlinearities is created in order to estimate jitter. A novel method for generating Gaussian distribution synthetic jitter patterns from colored noise profiles is also proposed.The Standard Organizations specify random and deterministic jitter budgets. In order to decompose the PLL output jitter (or the generated jitter from the proposed method), a new technique for jitter analysis and decomposition is proposed. Modeling simulation results correlate well with measurements and this technique will help designers to properly identify and quantify the sources of deterministic jitter and their impact on the SerDes system.We have developed a method, for specifying PLLs in terms of Phase Noise. This method works for any standard (USB, SATA, PCIe, …), and defines Phase noise profiles of the different parts of the PLL, in order to be sure that the standard requirements are satisfied in terms of Jitter.

Le risque de liquidité dans le système bancaire / Liquidity risk in the banking system

Costisor, Mihaela 02 April 2010 (has links)
Cette thèse étudie les différentes facettes du risque de liquidité et analyse le rôle essentiel qu'elles jouent dans la stabilité systémique.Dans la partie théorique de la thèse, nous traitons du risque de liquidité au travers des ruées bancaires. Progressivement, nous introduisons le marché interbancaire en tant que mécanisme d'assurance de liquidité entre les banques. Cependant, lorsqu'il y a une pénurie globale de liquidité, ce marché a tendance à favoriser la propagation d'une crise de liquidité de banque à banque, ce qui peut aboutir au risque systémique. Nous étudions de manière approfondie la littérature sur la contagion par les liens interbancaires et au travers des prix des actifs. / This thesis examines the different facets of the liquidity risk and aims to analyse their essential role in the stability of the financial system. In the theoretical part of the thesis, we treat liquidity risk through bank runs. Gradually, we introduce the interbank market as a liquidity insurance mechanism between banks. However, when there is an overall shortage of liquidity, this market tends to encourage the spread of liquidity crises from bank to bank which can lead to a systemic financial crisis. We study the literature on risk contagion by interbank links and through asset price effects. The applied part of the thesis aims to test the validity of hypotheses and insights presented in the theoretical framework. The goal is to betterunderstand the mechanism of liquidity risk and the forces of interaction between balance sheet effects that can lead to the transformation of liquidity risk into systemic risk caused by counterparty risk or the revaluation of tradable assets at market prices. In the first numerical application, we propose to evaluate the risk of contagion by interbank linkages in a context where banks borrow on the interbank market and/or at the central bank if necessary. The second simulation is dedicated to contagion through asset price effects, considering that the banks must sell assets on the market to meet their liquidity shortfall. If mark-to-market accounting is applied, the effects of the douwnturn in prices appear immediately and cause a spontaneous reaction from stakeholders.
