Cultes et identités en France au XVIIe siècle : étude des calendriers et des livres liturgiques / Cults and indentities in 17th century France : study of liturgical books and calendars

D'hour, Thomas 28 June 2014 (has links)
Le XVIIe siècle est généralement considéré comme un moment de romanisation des liturgies diocésaines françaises, sur le modèle des ouvrages romains réformés à la fin du XVIe siècle par Pie V (le nouveau Bréviaire romain est imprimé en 1568). Toutefois, force est de constater que chaque diocèse conserve une certaine marge de manœuvre, notamment pour la conservation d’usages particuliers s’ils sont en pratique depuis deux cents ans, ainsi que le prévoit la bulle Quod a Nobis.Ce travail s’intéresse, par le prisme des calendriers liturgiques diocésains et des livres qui les contiennent, aux conséquences de ce mouvement de romanisation sur les cultes et l’identité des diocèses. Pour l’essentiel, la méthode choisie consiste à saisir cent trente-cinq calendriers, imprimés entre 1570 et 1680 par soixante-dix diocèses, sous la forme d’une base de données et à les interroger en série. Plus particulièrement, les calendriers sont l’objet dans les premières années du XVIIe siècle de profondes réformes, tant dans leur structure que dans leur contenu. Ainsi, le calendrier romain et les offices de saints contenus dans le Bréviaire ne sont pas adoptés de la même manière dans l’ensemble des diocèses du royaume de France. Il est alors possible de construire une cartographie des différents degrés d’adoption du modèle romain et d’identifier des espaces. De même, tous les diocèses ne font pas état d’autant d’usages propres les uns que les autres, notamment au regard du nombre de saints.Enfin, ces cultes particuliers peuvent également être partagés entre plusieurs diocèses, dessinant alors de nouveaux espaces de dévotions à certains saints, à l’échelle de la France / Usually, the seventeenth century is considered as a time of romanisation of dioceses liturgy, following the model of Roman works that were reformed at the end of the 16th century by the pope Pie V (Roman breviary is printed in 1568). However, one has to come to the conclusion that each diocese keeps a certain margin especially concerning the conservation of particular uses if they had been in use for two hundred years, as scheduled by the bull Quod a Nobis.This study choses to show the consequences of the Roman reform on the identity and the worship of diocese through the prism of diocesan liturgic calendars and the books that contain them. Foremost, the chosen method consists in entering one hundred and thirty-five calendars, printed between 1570 and 1680 by seventy dioceses, in a data base and questionning them in series.More particularly, the calendars are the object in the early seventeenth century of deep reforms, in their structure as well as in their content. Hence, the Roman calendar and the saints services contained in the Breviary have not been adopted in the same way in all the dioceses of the French relm. It is then possible to build a cartography of the different degrees of adoption of the Roman model and identify spaces. In the same way, every diocese didn't mention as many particular uses as the others, especially in regard to the number of their own saints.Finally, these particular worships can be shared by several dioceses, defining new spaces of devotion to specific saints, on the French scale.

Étude du vieillissement des batteries lithium-ion dans les applications "véhicule électrique" : combinaison des effets de vieillissement calendaire et de cyclage / Study of lithium-ion batteries ageing in electric vehicle applications : calendar and cycling ageing combination effects

Redondo Iglesias, Eduardo 17 October 2017 (has links)
L'étude du vieillissement des batteries est nécessaire car la dégradation de leurs caractéristiques détermine en grande partie le coût, les performances et l'impact environnemental des véhicules électrifiés, notamment des véhicules 100 % électriques. La méthodologie choisie pour cette thèse consiste en deux étapes bien différenciées, à savoir la caractérisation et la modélisation. Pour la première étape, on s'appuie sur des essais de vieillissement accéléré d'éléments de batterie. Malgré leur caractère accéléré, les campagnes d'essais de vieillissement sont très coûteuses en moyens humains comme matériels : une connaissance à priori des facteurs de vieillissement est nécessaire, soit par le moyen d'études bibliographiques, soit par la réalisation de précampagnes d'essais. Ces études préalables conduisent à la conception d'un plan d'expériences composé d'un certain nombre d'essais dont les résultats permettront de révéler comment les conditions d'utilisation influencent la dégradation des batteries. Dans la seconde étape, grâce à la connaissance apportée par l'étape de caractérisation, on procède à la modélisation du vieillissement. Celle-ci permet de mettre en évidence des lois de vieillissement qui sont généralisées pour prédire l'évolution des performances d'une batterie soumise à des conditions d'utilisation variables dans le temps. Le modèle de vieillissement qui en résulte peut être utilisé pour concevoir et utiliser d'une manière optimale les batteries des véhicules pour minimiser à la fois la consommation d'énergie et de ressources naturelles. En sachant que la dégradation d'une batterie se produit différemment selon si elle est au repos ou si elle est parcourue par un courant, une difficulté majeure est celle de déterminer comment se combinent les effets du vieillissement calendaire et de cyclage pour un véhicule électrique. Dans les applications "véhicules électriques", les batteries passent une part importante de leur temps au repos et les niveaux de courant pendant leur utilisation sont relativement faibles. Les résultats des essais de vieillissement accéléré réalisés dans cette thèse confirment le caractère non-linéaire de la combinaison des vieillissements calendaire et en cyclage lorsque les batteries suivent des profils d'utilisation similaires à l'application considérée. Le modèle de vieillissement qui est proposé dans le dernier chapitre se veut simple mais efficace. Ainsi il repose sur un faible nombre d'équations (2) et de paramètres (6) et il permet de simuler l'évolution de la capacité d'une cellule soumise à un vieillissement qui combine des périodes de cyclage et de repos. Les exemples d'application de ce modèle démontrent son utilité pour l'établissement de stratégies d'utilisation de batteries dans le but de prolonger leur durée de vie / Studying the ageing of batteries is necessary because the degradation of their features largely determines the cost, the performances and the environmental impact of electric vehicles, particularly of full electric vehicles. The chosen method in this thesis is divided in two distinct phases, namely characterisation and modelling. The first phase is based on accelerated ageing testing of battery cells. Despite being accelerated, ageing test campaigns are expensive in terms of workforce and equipments: an a priori knowledge of ageing factors is necessary, either by the means of bibliographic studies or by performing preliminary test campaigns. These initial studies lead to an experimental design setup including a certain number of ageing tests. The obtained results may reveal the influence of use conditions on the degradation of batteries. In the second phase, the battery ageing is modelled applying the knowledge acquired in the first phase. Here, the ageing laws are generalised to predict the performance degradation of a battery subjected to variable use conditions. The resulting ageing model can be used to optimally design and use the battery in a vehicle by minimising both energy and natural resources consumption. Given that battery degradation occurs in a different way if the battery is in rest condition or if a current flows through, a major challenge is to determine how calendar and cycling ageing effects combine together. In electric vehicle applications, batteries are not used (in rest condition) most of the time and current levels are relatively low when they are used. The results from accelerated ageing tests which have been carried out during this thesis confirm the non-linearity of the combination of calendar and cycling ageing when usage profiles are applied to the batteries. The usage profiles are similar to the considered application: the electric vehicle. In the last chapter of this manuscript a simple but effective ageing model is proposed. It lies in a low number of equations (2) and parameters (6) and enables to simulate the capacity fade of a battery cell subjected to ageing conditions combining cycling and rest periods. The application examples prove the usefulness of this model for the development of battery use strategies for the purpose of extending their lifespan

As histórias mexicas coloniais: concepções de tempo e espaço (1530-1608) / The Colonial Mexicas Histories: Conceptions of Time and Space (1530-1608)

Martins, Eduardo Henrique Gorobets 20 March 2018 (has links)
O objetivo desta dissertação é entender as concepções de tempo e espaço presentes nos códices mexicas produzidos no período colonial inicial, entendendo-as como parte das concepções de história desse povo. Para alcançar esse objetivo foram analisadas centralmente as representações de calendário e lugares políticos e de paisagem em cinco narrativas históricas contidas nos códices mexicas produzidos durante os séculos XVI e início do XVII: Boturini, Mendoza, Aubin, Vaticano A e Manuscrito 40, manuscritos compostos por textos pictoglíficos e alfabéticos, produzidos pelas elites mexicas e seus descendentes, a partir de demandas nativas, castelhanas e missionárias. As representações temporais e espaciais levantadas nas narrativas foram cotejadas com exemplos de origem pré-hispânica, contidos nos códices mixtecos e nos monumentos e gravados em pedra mexicas, com a finalidade de inferir possíveis relações com permanências e transformações das concepções de tempo e espaço dos mexicas durante o período colonial inicial. O entendimento desse conjunto de concepções, centrados nas representações de calendário e de lugares políticos e de paisagem contidas nas narrativas históricas mexicas, pode contribuir para compreender como as elites mexicas e seus descendentes concebiam sua própria história após a conquista castelhana. / This Master thesis aims to comprehend the conceptions of time and space in the colonial Mexica or Aztec codices, assuming them as part of the Mexicas conceptions of history. To achieve this objective, the representations of calendar signs, political and landscape places were centrally analyzed in five historical narratives from Mexica codices produced during the 16th and early 17th centuries: Boturini, Mendoza, Aubin, Vaticano A and Manuscrito 40. These manuscripts produced by the Mexicas elites and their descendants, based on native, Castilian and missionary demands were composed by pictoglyphic and alphabetical texts. The time and space representations were analyzed and compared to pre-Hispanic samples at Mixtec codices and Mexicas stone monuments, for the purpose of infer the possible relations of persistence and transformation on the Mexicas conceptions of time and space during the early colonial period. The comprehension of this set of conceptions, centrally on the representations of calendar signs, political and landscape places, may contribute to understand how the Mexicas elites and their descendants conceived their own history after the Castilian conquest.

No. of bitstreams: 1 Joao Paulo Bocalon.pdf: 1733614 bytes, checksum: 2484a40aeed986b7942460522961c9c3 (MD5) Previous issue date: 2016-03-04 / This paper is aimed at assessing procedural agreements, such as the procedural flexibility technique, which is highly valued by Brazil's New Code of Civil Procedure. At the outset, this topic is researched from the standpoint of general procedural theory, in order to classify it within the context of its fundamental institutes. Later, this topic is looked at from the standpoint of general contract theory, confronting the problem regarding its defects and nullities. With these definitions, basic notions are established of the institute, such as concept, terminology, legal nature, guiding principles and a suggested classification. With the support of these technical cornerstones, the central problem is found, which is the pragmatic analysis of typical and atypical procedural contracts in Brazil's New Code of Civil Procedure. Keywords: Procedural agreements, Procedural flexibility, Procedural timetable, New Civil Code of Procedure / O presente trabalho objetiva analisar os negócios jurídicos processuais como técnica de flexibilização procedimental, valorizada pelo Novo Código de Processo Civil. Em um primeiro momento, o tema é pesquisado sob a ótica da teoria geral do processo, de sorte a enquadrá-lo no contexto de seus institutos fundamentais. Após, o tema é analisado sob a ótica da teoria geral dos negócios jurídicos, enfretando a problemática referente aos seus vícios e nulidades. Com essas definições, estruturamos as noções basilares do instituto, como conceito, terminologia, natureza jurídica, princípios norteadores e uma sugestão de classificação. Amparado nesses pilares teóricos, chegamos à problemática central, qual seja, a análise pragmática dos negócios processuais típicos e atípicos no Novo Código de Processo Civil

Capitalizing on seasonalities in the Singapore Straits Times Index

Hetting, Oscar, Hellman, Joakim, Tarighi, Maryam January 2012 (has links)
Purpose: The purpose of this thesis is to study the possible existence of day-of-the-week effects and month-of-the-year effects in the Singapore stock market over the period January 1st 1993 to December 31st 2011. The findings are analysed with the intention of developing investment strategies and to investigate if behavioural finance can help to explain the existence of seasonal anomalies.  Background: A number of previous studies have found evidence of seasonal anomalies in global stock markets, and by challenging the core assumptions of market efficiency, such anomalies may make it possible to predict the movement of stock prices at certain periods during the year. Consequently, there may be substantial profit-making opportunities that clever investors can benefit from, raising two important questions: (1) can such anomalies be strategically used to outperform the market and (2) why do such cyclical return patterns exist? Method: Daily closing prices from the Singapore Straits Times Index (STI) are used to compute average daily and monthly returns, which are further analysed through the use of statistical significance analysis and hypothesis testing to identify the possible existence of day-of-the-week effects and month-of-the-year effects in the Singapore stock market.  The results of the statistical investigation are used to develop investment strategies that are designed to take advantage of both positive and negative effects, and the theories of behavioural finance are applied to help explain why seasonalities occur at certain points in time. Conclusions: This study finds evidence of several seasonal anomalies in the Singapore stock market. Both day-of-the-week effects and month-of-the-year effects are present in the STI over the full sample period. Many of these effects can be explained by behavioural finance, and used to develop investment strategies that outperform the market.

Το "Ημερολόγιον των Κυριών" του Ειρηναίου Ασώπιου : συμβολή στο γυναικείο ζήτημα στα τέλη του 19ου αιώνα

Παπαγιαννοπούλου, Ευσταθία 02 March 2015 (has links)
Αντικείμενο της παρούσας μελέτης είναι το "Ημερολόγιον των Κυριών: ευγενεί συνεργασία ευπαιδεύτων δεσποινών και δεσποινίδων" του Ειρηναίου Ασώπιου, που εκδόθηκε στην Αθήνα ως παράρτημα του "Αττικού Ημερολογίου" κατά το διάστημα 1888-1890, με ξεχωριστή σελιδαρίθμηση. Στόχος είναι η ανάδειξη των ιδιαίτερων χαρακτηριστικών του ημερολογίου, μέσα από το περιεχόμενο και τον χαρακτήρα της ύλης που δημοσιεύει, εστιάζοντας, κυρίως, στη συμβολή του στο γυναικείο ζήτημα. Η εργασία είναι διαρθρωμένη σε τρία κεφάλαια. Στο πρώτο κεφάλαιο επιχειρείται μια σύντομη επισκόπηση των γυναικείων περιοδικών του 19ου αιώνα στην Αθήνα και στην Κωνσταντινούπολη πριν από το "Ημερολόγιον των Κυριών". Το δεύτερο κεφάλαιο εστιάζει στις ανδρικές και γυναικείες συνεργασίες του ημερολογίου, καθώς επίσης στην ύλη του. Περιγράφεται η διάρθρωση της ύλης, με ιδιαίτερη έμφαση στα λογοτεχνικά κείμενα (πρωτότυπα και μεταφρασμένα) και τις βιογραφίες. Στο τρίτο και τελευταίο κεφάλαιο εξετάζεται αφενός η χρήση της ιστορίας για την προώθηση του γυναικείου ζητήματος και αφετέρου ο τρόπος με τον οποίο παρουσιάζεται η θέση της γυναίκας μέσα από τα κείμενα του ημερολογίου. / This study focuses on "Ladies Calendar" which was published as annex of "Atticus Calendar" by E. Asopios between 1888-1890.The purpose of the study is to highlight specific characteristics of the calendar through its content.The work is structured in three chapters. The first chapter is a brief overview of women's magazines in Athens and Istanbul before "Ladies Calendar". The second chapter focuses on calendar's male and female writers. In this part is described its structure with particular emphasis on literary texts (original and translated) and biographies. The third and final chapter examines both the use of history for the promotion of women's issue and the way in which the status of women through the calendar's texts is presented.

Trends in Early Marriage in Shashemene, Ethiopia

Mutgan, Selcan January 2014 (has links)
Despite the Family Code of 2000 that raised the legal age at marriage to 18 for both sexes; early family formation is still a common practice which affect many children in Ethiopia. Previous research has shown that girls in rural areas are more disadvantaged and suffer the consequences of early marriage the most. The purpose of this thesis is to study the risk factors for early marriage for both girls and boys in an urban area, Shashemene. Also, using longitudinal data, trends in early family formation between 1973 and 2008 have been analyzed with an event history approach. The data were collected as part of the project “Changing Ethiopia: Urban livelihood, gender, and ethnicity in Shashemene after 35 years: A case study”. The discrete-time complementary log-log regression estimates have provided evidence of gender inequality in early marriage formations, showing that girls are more prone to experience early marriage than boys. While area of birth (rural-urban) has no direct impact on the risk of early marriage, it is found that living in an urban area offsets the effect of area of birth, suggesting a selection process into migration. It is also found that school attendance decreases the likelihood of early marriage, while literacy has little effect. Moreover, among people living in Shashemene, religious affiliation has more impact on early marriage risks than ethnic identity and the first language. Finally, there was little evidence on period and cohort effects for early family formation.
