La spécialisation du travail artisanal dans la civilisation de l'IndusBrisset, Isabelle 08 1900 (has links)
La civilisation de l’Indus marque les esprits par une apparente uniformité de la culture matérielle sur la totalité de son territoire (environ 1 million de km carré) durant sa période d’apogée (2600-1900 av. J.-C.). Cette étude cherche à tester deux hypothèses qui pourraient expliquer cette homogénéité : 1) Un pouvoir centralisateur contrôlant la production artisanale; et 2) Un vaste réseau d’échanges et de distribution de la production. Dans ce but, la grande majorité des publications accessibles portant sur la production artisanale d’objets en céramique, en pierres semi-précieuses, en coquillage et en métal ont été inventoriées et analysées. Axée sur la spécialisation du travail artisanal, l’étude a identifié quelques objets dits de prestige (perles classiques harappéennes, bracelets en grès cérame) très probablement liés à une élite. La nature de cette élite est ensuite examinée et un nouveau modèle d’organisation sociopolitique de cette civilisation est proposé. / The Indus civilization puzzles archaeologists in that it shows a seeming uniformity in its material culture during the period from 2600 to 1900 BC and over its huge geographical extent (approximately 1 million square km). In this study two hypotheses are tested: 1) This uniformity in material culture is due to a central political force monitoring craft production; or 2) This uniformity results from an extensive trade and distribution network of craft production. In order to assess these, all available data concerning the craft production of ceramic, lapidary, shell-working and metal artefacts were inventoried and analyzed. A study of craft specialization identified a few wealth items (long carnelian beads, stoneware bangles), which were most probably related to an elite. After reassessing the nature of this elite, a new model of sociopolitical organization for this civilization is proposed.

Predictability of a laboratory analogue for planetary atmospheresYoung, Roland Michael Brendon January 2009 (has links)
The thermally-driven rotating annulus is a laboratory experiment used to study the dynamics of planetary atmospheres under controlled and reproducible conditions. The predictability of this experiment is studied by applying the same principles used to predict the atmosphere. A forecasting system for the annulus is built using the analysis correction method for data assimilation and the breeding method for ensemble generation. The results show that a range of flow regimes with varying complexity can be accurately assimilated, predicted, and studied in this experiment. This framework is also intended to demonstrate a proof-of-concept: that the annulus could be used as a testbed for meteorological techniques under laboratory conditions. First, a regime diagram is created using numerical simulations in order to select points in parameter space to forecast, and a new chaotic flow regime is discovered within it. The two components of the framework are then used as standalone algorithms to measure predictability in the perfect model scenario and to demonstrate data assimilation. With a perfect model, regular flow regimes are found to be predictable until the end of the forecasts, and chaotic regimes are predictable over hundreds of seconds. There is a difference in the way predictability is lost between low-order chaotic regimes and high-order chaos. Analysis correction is shown to be accurate in both regular and chaotic regimes, with residual velocity errors about 3-8 times the observational error. Specific assimilation scenarios studied include information propagation from data-rich to data-poor areas, assimilation of vortex shedding observations, and assimilation over regime and rotation rate transitions. The full framework is used to predict regular and chaotic flow, verifying the forecasts against laboratory data. The steady wave forecasts perform well, and are predictable until the end of the available data. The amplitude and structural vacillation forecasts lose quality and skill by a combination of wave drift and wavenumber transition. Amplitude vacillation is predictable up to several hundred seconds ahead, and structural vacillation is predictable for a few hundred seconds.

La parure chypriote de la fin de l'âge du bronze à l'époque archaïque, étudiée dans le contexte de la Méditerranée orientale / Protohistoric Jewellery from Cyprus (ca. 1200-600 BC). A comparative study in the context of the Eastern MediterraneanPaule, Anna 13 May 2013 (has links)
L'apparition de parures de style oriental (ou « phénicien ») sur des sites chypriotes et égéens entre le XIIe et le VIIe s. av. J.-C. est un phénomène bien attesté. Sélectionnées sur le critère d'une ressemblance visible, on peut dresser une liste de parures, réalisées en or ou d'autres matières telles que le bronze, trouvées sur le continent grec (Tirynthe, Perati) et sur îles égéennes (Crète, Naxos, Kos et Rhodes).Cependant, la nature de ces échanges, qui ne suivent pas un schéma régulier, reste difficile à cerner. D'une part, il existe des parallèles visiblement étroits entre les parures chypriotes et d'autres découvertes en dehors de cette île. Elles semblent être issues de contacts directs entre les régions. L'étude sur leurs modèles de diffusion et d'autres, qui concernent les produits en métal plus que la céramique, permettent d'aller au-delà d'une étude comparative des parures. Ainsi, il s'est avéré que les contextes contenant non seulement des parures mais aussi d'autres objets d'aspect étranger sont relativement fréquents. Outre ce matériel, nous sommes confrontés à d'autres parures qui ne sont comparables que sous réserve. Leur apparence suggère la présence de contacts indirects, donc une circulation d'idées plutôt que d'objets. En ce qui concerne des futures études, les résultats des fouilles récentes menées sur le site postpalatial de Tirynthe se sont avérés particulièrement intéressants. De plus, il faut signaler que la question de l'origine de la fibule pose un problème qui n'a pas encore été résolu. / The appearance of jewellery of Near-Eastern origin at Cyprus and Greece is a well-known phenomenon which we meet also from the 12th to the 7th century BC. Well-known examples made from gold and from bronze were found at the Greek continent (Tiryns, Perati) and at the Aegean islands (Crete, Naxos, Kos, Rhodes).The nature of these overseas exchanges, however, can hardly be determined and does not follow any regular system. At the one hand, there are striking parallels between certain Cypriot pieces of jewellery and other specimens found outside of Cyprus. They seem to be the result of direct contacts. The studies of the contexts to which these objects belong allow us to go beyond the mere documentation of jewellery. Following this approach, it is evident that various tombs contained not only pieces of jewellery, but also other foreign objects. This seems to support our hypotheses about on-going overseas contacts. At the other hand, there are a number of items which appear to be local products inspired from Cypriot art. Obviously, they are the result of indirect contacts or of a spreading of ideas.Regarding future studies about Cypriot or Cypriot-inspired objects, the more recent discoveries made in Tiryns are particularly noteworthy. Furthermore, one has to consider that the problems related to the origin of the fibula, which occurs at the end of the Late Bronze Age, have still not been resolved.

"Jeder Engel ist schrecklich. Und dennoch"Gille, Caroline 14 August 2015 (has links)
Engel definieren sich vor allem durch ihre Undefinierbarkeit, ihre Zwischenwesenhaftigkeit. Das Spannungsfeld unvereinbarer Bereiche ermöglicht den Engeln die Existenz. Um ihre Aufgaben – besonders die des Mittlers bzw. Boten – zu erfüllen, können sie fliegen. Jeder Engel, schreibt Rilke, sei schrecklich. Als besonders schrecklich mögen diejenigen Engel sein, die gefallen sind. Ausgewählte Fall-Studien zu ihnen stehen im Zentrum dieser Arbeit. Engel büßen bei ihrem Fall die Fähigkeit zu fliegen und ihre privilegierte Position ein. Auf sich gestellt, zeigen gefallene Engel zwei Reaktionsmuster: Macht und Melancholie. Mächtigen gefallenen Engel gelingt es – oder: sie beabsichtigen es –, die Beziehungsrelation zur göttlichen Autorität nach ihrem Fall aufrechtzuerhalten bzw. neu zu definieren: Durch Errichtung neuer Reiche, rebellischer und sinnlicher, führen sie die Versuchung fort. Aber sie sind keine Mittler mehr, weil sie keine Mitteilungen mehr empfangen, sondern Botschafter eigener Botschaften. Melancholische gefallene Engel lassen dagegen die nutzlos gewordenen Flügel hängen. Auch sie haben vor ihrem Fall in einem Beziehungsverhältnis existiert. Fällt das Gegenüber weg, sinkt ihre Erscheinung in sich zusammen, erlischt ihre Botenfunktion, senden und empfangen sie nicht bzw. nichts Neues mehr. Macht und Melancholie sind in aber auch Aktionsfelder. Der Künstler reflektiert in der objektiv – für sein künstlerisches Schaffen – wie subjektiv – für sein künstlerisches Selbstverständnis – genutzten Identifikationsfigur des gefallenen Engels beide Positionen. So greifen Macht und Melancholie, Rebellion und Resignation, Schöpfen und Scheitern ineinander. Gefallene Engel sind eigentlich ihres Botenstatus’ beraubt. Doch haben sie eine einzige letzte Botschaft – sie sind selbst die Botschaft vom Ursprung ihres Falls und haben darin ihr Ziel. / Angels are defined above all by their indefinability, their mutable essence. The conflict zone between irreconcilable areas makes the existence of angels possible. To fulfill their function – in particular that of medium or messenger – they can fly. Every angel, Rilke wrote, is terrifying. Most terrifying among the angels are, perhaps, those that have fallen. Selected case studies of those form the core of this dissertation. When angels are cast out of heaven, they forfeit their capacity for flight and their privileged position. Left to their own defenses, fallen angels display one of two reaction modes – might or melancholy. Mighty fallen angels are able – or they aim – to maintain their relationship with divine authority, or to redefine it, after the fall. By erecting new realms, more rebellious and sensual, they carry on with temptation. But they are no longer media, because they no longer receive communications. Rather they are the messengers of their own message. Melancholy fallen angels, on the other hand, let their now-useless wings droop. They too existed in a relationship before the fall. When their vis-à-vis disappears, their apparition caves in; their messenger function extinguished, they send and receive nothing or at least nothing new. Yet might and melancholy are not only reaction modes, but also fields of action. The artist, in using the identification figure of the fallen angel both objectively – for his or her artistic creation – and subjectively – for his or her sense of artistic self, reflects both positions. So might and melancholy, rebellion and resignation, creation and collapse mesh. Fallen angels are in fact robbed of their messenger status because, unable to fly, they are no longer a medium. But they do have just one last message – they are themselves the message of the origins of their fall, and that is their goal.

The images of space in the Third Sibylline OracleJacobs, Deborah 25 March 2014 (has links)
Von Haus aus sind Sibyllinische Orakel eine griechisch-römische Literaturgattung, eine Sammlung von Orakelsprüchen in griechischen Hexametern, die nicht erhalten ist. Die uns überlieferten Sibyllinischen Orakel sind jüdischen, christlichen und teilweise paganen Ursprungs. Die insgesamt 14 Bücher sind in den Jahren 150 vor bis 300 nach Christus entstanden. Bis zu ihrer Wiederentdeckung im Vatikan waren die Sibyllinischen Orakel nur durch Zitate der Kirchenväter bekannt. Buch 3 ist laut Mehrheit der Forscher das älteste der Sammlung und entstand im zweiten vorchristlichen Jahrhundert in Ägypten. Die Arbeit stellt diesen Konsens in Frage. Sie konzentriert sich dabei auf die Vorstellung der Beherrschung des Raumes im dritten Sibyllinischen Orakel. Dabei geht es einerseits um die rein geographische Vorstellung der Welt, die der Sibylle zugrunde liegt und andererseits um die politisch-theologische Vorstellung der Abfolge von Weltreichen, die diese Welt nacheinander beherrschen und schlussendlich von der Herrschaft Gottes abgelöst werden. Das Thema Gottesherrschaft nimmt in den jüdischen Pseudepigraphen eine relativ marginale Rolle ein. Dies könnte sicherlich damit zusammenhängen, dass die Diasporaschriften nicht unmittelbar unter dem Einfluss der sogenannten Antiochenischen Verfolgung und den Makkabäeraufständen standen, anders als z.B. das Danielbuch. In den Texten aus der Diaspora findet sich das Thema Gottesherrschaft sogar nur im dritten Sibyllinischen Orakel und in der Weisheit Salomos. Besonderes Gewicht hat die Gottesherrschaft schließlich in den Schriften des Neuen Testament. Ich hoffe mit meiner Arbeit einen wichtigen Beitrag zur Genese der Vorstellung der Gottesherrschaft im Neuen Testament zu leisten. Der endzeitliche Zustand, den die Sibylle für die Umsetzung der göttlichen Herrschaft auf Erden prophezeit, kann mit dem Begriff Utopie beschrieben werden. / Originally, the Sibylline Oracles were a Graeco-Roman literary genre, namely a collection of oracles composed in Greek hexamters which have not come down to us. The Sibylline Books that we have today are of Jewish and Christian origin and stem from a time when the genre was adapted first by Jews and then Christians. The altogether 14 books have developed between 150 BCE and 300 CE and for the longest time were only known through quotations in the church fathers such as Eusebius and Lactantius. According to the majority of scholars, Book III is the oldest of the Sibylline corpus and developed in the 2nd century BCE in Egypt. This thesis reconsiders the established consensus using old and new evidence alike. It focuses on the image of dominion of space in the Third Sibyl. On the one hand, space is looked at as the geographical image of the world as the Sibyl has access to, on the other, space is looked at as the political-theological image of succession of empires that rule the world consecutively until eventually they are superseded by the dominion of God. The dominion of God only play a minor role in Jewish pseudepigraphy. This could be related to the fact that the writings of the Diaspora were not immediately affected by the so-called Antiochene persecution and the Maccabean revolt unlike, for instance, the Book of Daniel. In the writings of the Diaspora the topic only occurs in the Third Sibyl and in the Wisdom of Solomon. It becomes particularly important in the New Testament. With this thesis I hope to provide an important contribution to the genesis of the image of the dominion of God in the New Testament. The eschatological age that the Sibyl prophecies for the establishment of the divine dominion on earth can be described using the term utopia.

La réception du théâtre d’Aristophane dans la littérature grecque de l’époque impériale / The reception of Aristophanes’s theatre work in Greek literature of the Roman periodLebon-Samborski, Émilie 06 December 2019 (has links)
La comédie d’Aristophane est abondamment reçue et réécrite par la littérature grecque de l’époque impériale. À partir de l’histoire de la transmission des pièces, rarement rejouées entre leur création et les deux premiers siècles de notre ère, mais diffusées et réinterprétées par différents canaux, iconographiques ou textuels, la thèse étudie la place et le rôle de ce théâtre dans le paysage culturel du Haut-Empire, et plus spécifiquement chez les prosateurs grecs. Le statut de ce théâtre paraît de prime abord problématique : il est souvent entouré de silence, voire d’un blâme théorique, surtout quand on l’oppose à Ménandre ; mais les écrivains, dans des genres et des formes très variés, se le sont pleinement approprié. De nombreux enjeux caractérisent la réécriture des comédies : enjeux historiques et linguistiques, grâce à l’ancrage des textes dans un contexte et une langue attiques et à la réserve de realia que représentent les comédies et qui contribuent à instaurer et affermir l’hellénisme des pépaideumenoi de l’Empire ; enjeux moraux et comiques, notamment par la satire et la parodie ; plus largement, des enjeux poétiques et rhétoriques : ce théâtre est devenu un vecteur reconnu d’images et un garant de créativité et d’autorité. Deux études de cas portent sur des auteurs emblématiques de la période, Plutarque de Chéronée et Lucien de Samosate : les usages qu’ils font de la référence aristophanienne sont protéiformes et marqués par une grande ambiguïté, que cette thèse tente d’élucider. / The reception of Aristophanes’s comedy in the Greek literature of the Roman Empire is extensive. Based on the history of transmission of the comedies, which from their creation to the the first two centuries AD were rarely performed on stage but spread and re-interpreted by different means, whether iconographic or textual, this dissertation studies the place and role of this theatre in the cultural landscape of the Roman Empire, specifically in the work of Greek prose writers. The status of this theatre seems at first sight quite problematic: it is rarely mentioned and if mentioned it is spoken of with theoretical disapproval, yet the writers, in various literary genres and forms, fully appropriated it. The rewriting of the comedies is at stake on many levels: on the historic and linguistic levels, in the light of how these texts are anchored in the Attic context and language, and the stock of realia they contain, which contributes to demonstrating the "pepaideumenoi"‘s hellenism in the Empire; on the moral and comic levels, too, as well with satires and parodies; and to a larger extent on the poetic and rhetorical levels, this theatre becomes a conveyor of images and guaranteeing creativity and authority. Two case studies were presented here about emblematic writers of the imperial period, Plutarch of Chaeronea and Lucian of Samosata: they make protean and ambiguous use of the reference to Aristophanes, that this dissertation attempts to clarify.

Predicting Workforce in Healthcare : Using Machine Learning Algorithms, Statistical Methods and Swedish Healthcare Data / Predicering av Arbetskraft inom Sjukvården genom Maskininlärning, Statistiska Metoder och Svenska SjukvårdsstatistikDiskay, Gabriel, Joelsson, Carl January 2023 (has links)
Denna studie undersöker användningen av maskininlärningsmodeller för att predicera arbetskraftstrender inom hälso- och sjukvården i Sverige. Med hjälp av en linjär regressionmodell, en Gradient Boosting Regressor-modell och en Exponential Smoothing-modell syftar forskningen för detta arbete till att ge viktiga insikter för underlaget till makroekonomiska överväganden och att ge en djupare förståelse av Beveridge-kurvan i ett sammanhang relaterat till hälso- och sjukvårdssektorn. Trots vissa utmaningar med datan är målet att förbättra noggrannheten och effektiviteten i beslutsfattandet rörande arbetsmarknaden. Resultaten av denna studie visar maskininlärningspotentialen i predicering i ett ekonomiskt sammanhang, även om inneboende begränsningar och etiska överväganden beaktas. / This study examines the use of machine learning models to predict workforce trends in the healthcare sector in Sweden. Using a Linear Regression model, a Gradient Boosting Regressor model, and an Exponential Smoothing model the research aims to grant needed insight for the basis of macroeconomic considerations and to give a deeper understanding of the Beveridge Curve in the healthcare sector’s context. Despite some challenges with data, the goal is to improve the accuracy and efficiency of the policy-making around the labor market. The results of this study demonstrates the machine learning potential in the forecasting within an economic context, although inherent limitations and ethical considerations are considered.

The importance of counter-culture in art and lifeOrtlieb, Paulina Elizabeth 03 February 2015 (has links)
Punk rock provided not only a watershed of creativity, innovation and a do-it-yourself spirit to a culture saturated in the mainstream, it physically brought like-minded people together in a community, or rather extended family, which in today’s hyper-d.i.y. culture, is progressively declining. As early as the 1940s, theorists such as Adorno and Horkheimer warned us about alienation in a society increasingly dependent on technology. By looking to punk, and other resilient and robust counter-cultures, perhaps we can find solutions to the pitfalls of the ‘culture industry’ (Adorno, Horkheimer, 1944).
My thesis, consisting of a feature-length documentary film and textual analysis, is a culmination of: ethnographic research into the punk scene in my own community; theoretical research into the sociology, ethnography and subculture theory; and my own subjectivity. My personal findings are presented to offer insight into punk philosophy and to spur discourse, rather than deliver an objective account or didactic reproach. / Graduate

Características do envolvimento do Sistema Nervoso Central na Polirradiculoneuropatia Inflamatória Desmielinizante Crônica: um estudo mediante técnicas quantitativas de Imagem por Ressonância Magnética / Characteristics of involvement of the central nervous system in chronic inflammatory demyelinating polyneuropathy: a quantitative magnetic resonance imaging study.Carmo, Samuel Sullivan 27 June 2014 (has links)
A polineuropatia inflamatória desmielinizante crônica (PIDC) é uma síndrome caracterizada fundamentalmente pela disfunção do Sistema Nervoso Periférico e que afeta muito a qualidade de vida dos pacientes. O envolvimento da PIDC com o Sistema Nervoso Central tem sido descrito, maiormente como sendo subclínico, porém não há estudos sobre a caracterização deste envolvimento de uma forma ampla e quantitativa. Avaliamos 11 pacientes com PIDC, todos tratados e sem sinais clínicos de alterações centrais, e 11 controles, pareados em gênero e faixa etária de 19 a 69 anos. Foram adquiridas neuroimagens em uma máquina de Ressonância Magnética de alto campo (3T) usando diferentes técnicas de imagens; volumétricas ponderadas em T1, volumétricas de inversão e recuperação com atenuação de fluidos e ponderadas em T2, relaxométricas de cinco ecos para mapas de T2, de transferência de magnetização e por tensor de difusão. As imagens foram processadas em diferentes ferramentas computacionais e foram obtidos resultados para estudos da difusibilidade, volumetria, morfometria, tratometria e conectividade cerebral, além de achados radiológicos para os pacientes. As análises de grupos foram executadas por; 1) testes paramétricos monocaudais de duas amostras pareadas para os resultados da volumetria, da tratometria e conectividade cerebral; 2) mapeamento estatístico paramétrico para os resultados da morfometria baseada em voxel e; 3) estatística espacial baseada em tratos para os resultados da difusibilidade. Foram detectas alterações em todas as comparações. Os principais achados indicam um envolvimento possivelmente caracterizado por uma perda volumétrica encefálica generalizada, sobretudo nas regiões periventriculares associadas a ventrículos proeminentes acrescido de, um aumento da difusibilidade transversa e oblíqua nos maiores tratos de substância branca e, também há uma perda de densidade na substância branca periventricular e um aumento na substância cinzenta em uma região que sinaliza para o espessamento trigeminal bilateral e, uma redução geral da conectividade cerebral estrutural. / Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) is a severe disease fundamentally characterized by dysfunction of the Peripheral Nervous System and affects greatly the quality of life of patients. The Central Nervous System (CNS) involvement in CIDP has not been described using recent quantitative neuroimaging techniques. We evaluated 11 patients with CIDP, all treated and without clinical signs of central alterations and 11 controls matched for gender and age group of 19 to 69 years. Magnetic Resonance Imaging were performed on a 3T scanner using different imaging techniques; structural 3D T1-weighted, fluid-attenuated inversion recovery, relaxometry with 5 echoes pulse sequence for T2 maps, magnetization transfer weighted and diffusion tensor imaging. The images were processed on different tools and were obtained results for the studies of diffusivity, volumetry, morphometry, tractometry, brain connectivity, and radiological findings of patients. Different statistical group analyses were performed in the quantitative results: 1) Parametric test for volumetry, tractometry and brain connectivity; 2) Parametric mapping for voxel morphometry; 3) Tract-based spatial statistics (TBSS) for diffusion coefficients. Changes were detected in all comparisons. In the patients, our main findings are: generalized loss brain volume more pronounced in periventricular regions associated with prominent ventricles, increased simultaneously perpendiculars and parallel diffusivity in the major tracts of the TBSS analyze, white matter density loss in the periventricular area, some bilateral trigeminal thickening, and general reduction of the brain connectivity. The CIDP affects the global brain and represents a demyelination in the CNS.
