Abstract:
Der Baikalsee ist ein ideales Klimaarchiv für die Mitte Eurasiens. In dieser Arbeit wurde gesteinsmagnetische und paleomagnetische Analysen an hemipelagischen Sequenzen von vier Lokationen analysiert. Die Kerne erreichen ein Alter von maximal 300 ky. In Kombination mit TEM, XRD, XRF und geochemischen Analysen zeigt die gesteinsmagnetische Studie, dass detritischer Magnetit das magnetische Signal der glazialen Sedimente dominiert. Die magnetischen Signale der interglazialen Sedimente wurden durch diagenetische Prozesse verändert. Mittels HIRM können Hämatit und Goethit quantifiziert werden. Diese Methode eignet sich, den detritischen Eintrag in den Baikalsee abzuschätzen. Relative Paleointensitäten des Erdmagnetfeldes ergaben reproduizerbare Muster, welche in Korrelation mit gutdatierten Referenzproben die Ableitung eines alternativen Altersmodells für die Datierung der Baikalsedimente ermöglichten. Bei Anwendung des paleomagnetischen Altersmodells beobachtet man, dass die Abkühlung im Baikalgebiet und im Oberflächenwasser des Nordatlantiks wie sie aus den &#948;18 O-Werten planktonischer Foraminiferen abgeleitet werden kann, zeitgleich ist. Wird das aus benthischen &#948;18 O-Werten abgeleitete Altermdodell auf den Baikalsee angewandt, ergibt sich eine deutliche Zeitverschiebung. Das benthische Altersmodell repräsentiert die globale Veränderung des Eisvolumens, welche später als die Vänderung der Oberflächenwassertemperatur auftritt. Die Kompilation paleomagnetischer Kurven ergab eine neue relative Paleointensitätskurve &ldquo;Baikal 200&rdquo;. Mittels Korngrössenanalyse des Detritus konnten drei Faziestypen mit unterschiedlicher Sedimentationsdynamik unterschieden werden: 1) Glaziale Peroiden werden durch hohe Tongehalte infolge von Windeintrag und durch grobe Sandfraktion mittels Transport durch lokale Winde über das Eis charakterisiert. Dieser Faziestyp deutet auf arides Klima. 2) Während der Glazial/Interglazial-Übergänge steigt die Siltfraktion an. Dies deutet auf erhöhte Feuchtigkeit und damit verbunden erhöhte Sedimentdynamik. Windtransport und in den Schnee der Eisdecke eingetragener Staub sind die vorherrschenden Prozesse, welche den Silt in hemipelagischer Position zur Ablagerung bringen. 3) Während des klimatischen Optimum des Eeemian werden Grösse und Quantität des Silts minimal, was auf eine geschlossene Vegetationsdecke im Hinterland deutet.<br>Lake Baikal provides an excellent climatic archive for Central Eurasia as global climatic variations are continuously depicted in its sediments. We performed continuous rock magnetic and paleomagnetic analyses on hemipelagic sequences retrieved from 4 underwater highs reaching back 300 ka. The rock magnetic study combined with TEM, XRD, XRF and geochemical analyses evidenced that a magnetite of detrital origin dominates the magnetic signal in glacial sediments whereas interglacial sediments are affected by early diagenesis. HIRM roughly quantifies the hematite and goethite contributions and remains the best proxy for estimating the detrital input in Lake Baikal. Relative paleointensity records of the earth&prime;s magnetic field show a reproducible pattern, which allows for correlation with well-dated reference curves and thus provides an alternative age model for Lake Baikal sediments. Using the paleomagnetic age model we observed that cooling in the Lake Baikal region and cooling of the sea surface water in the North Atlantic, as recorded in planktonic foraminifera &#948;18 O, are coeval. On the other hand, benthic &#948;18 O curves record mainly the global ice volume change, which occurs later than the sea surface temperature change. This proves that a dating bias results from an age model based on the correlation of Lake Baikal sedimentary records with benthic &#948;18 O curves. The compilation of paleomagnetic curves provides a new relative paleointensity curve, &ldquo;Baikal 200&rdquo;. With a laser-assisted grain size analysis of the detrital input, three facies types, reflecting different sedimentary dynamics can be distinguished. (1) Glacial periods are characterised by a high clay content mostly due to wind activity and by occurrence of a coarse fraction (sand) transported over the ice by local winds. This fraction gives evidence for aridity in the hinterland. (2) At glacial/interglacial transitions, the quantity of silt increases as the moisture increases, reflecting increased sedimentary dynamics. Wind transport and snow trapping are the dominant process bringing silt to a hemipelagic site (3) During the climatic optimum of the Eemian, the silt size and quantity are minimal due to blanketing of the detrital sources by the vegetal cover.

Abstract:
Cette recherche doctorale repose sur l’analyse des collections archéologiques de la nécropole de Koban, découvertes par Ernest Chantre, actuellement conservées au musée d'archéologie nationale de Saint-Germain en Laye et au musée des Confluences à Lyon. La nécropole de Koban située dans le Nord Caucase fût découverte par Ernest Chantre en 1881. Le site de Koban a donné son nom à l’une des cultures du Bronze récent et du premier âge du Fer du Nord Caucase. Cette thèse porte sur l’ensemble des objets mis au jour à Koban, publiés et non publiés. Par une analyse systématique innovante, cette recherche a permis d’élaborer une classification typologique. Ces données ont été comparées avec du matériel provenant d’autres régions du Caucase. Cetteanalyse des objets a notamment permis de comprendre l’environnement culturel de la nécropole de Koban soulignant ainsi des influences d’autres régions du Caucase – Colchis and Shida Kartli. L’une des composantes majeures de cette recherche est la reconstruction des assemblages funéraires de Koban, qui montrent des aspects inconnus à ce jour. De nouvelles datations radiocarbones réalisées sur la tombe 9 nous ont également permis de réexaminer de façon extensive la chronologie de la nécropole de Koban<br>This work examines Ernest Chantre’s archaeological collections from the Koban necropolis, stored at the National Archaeological Museum of France, at Saint-Germain-en-Laye and the Confluences Museum in Lyon. The Koban necropolis, which was excavated by Chantre in 1881, is located in the North Caucasus. It has given its name to one of the Late Bronze and Early Iron Age cultures of the Caucasus.This dissertation brings to light Koban objects, both published and unpublished, and organizes themin a systematic fashion. Typological classification of each group of objects is examined andpresented. These data are then compared with materials from other parts of the Caucasus. The focus of the research determines the cultural environment of the Koban necropolis in the Caucasus region, as objects from this site reflect certain characteristic features of different regions of the Caucasus such as Colchis and Shida Kartli.One of the main components of this dissertation is the reconstruction of Koban funeral assemblages.These are presented differently here than has previously been done. Along with presenting the assemblages, radiocarbon data is also presented from grave no. 9, which enables us to re-examine, to an extent, the chronology of Koban necropolis

Abstract:
Au XIXe siècle, les premiers espaces protégés d'Occident durent lier une mission de protection de l'environnement à celle d'accueil du public, et notamment des touristes. Ce double objectif se retrouve aujourd'hui dans des espaces protégés qui se veulent,depuis 1970, intégrateurs. Une première étude (2006-2008) au sein d'un Parc Naturel Régional avait révélé l'existence d'une tension entre l'objectif de protection et celui de développement touristique : les touristes y étaient perçus comme une menace, et les gestionnaires se consacraient plus volontiers à la protection. Dans cette thèse, nous avons voulu prolong er la réflexion à partir de trois espaces : le Parc National du Lake District (Royaume-Uni), l'Espace Naturel de Doñana(Espagne) et le Parc Naturel Régional du Verdon (France). Notre enjeu est de vérifier si la même tension entre protection environnementale et développement touristique y est sensible, dans quelle mesure, et pour quelles raisons cette tension se manifeste (ou non) .Après une analyse de contenu mettant en lumière la façon plutôt sévère dont le tourisme est traité dans les discours, l'étude de l'aménagement des espaces, du système d'acteurs en présence et des chiffres du tourisme montrent une rupture totale entre les espaces protégés, leurs gestionnaires et les touristes dont les pratiques ne sont pas comprises ni acceptées. L'étude de facteurs culturels et historiques permettant d'explique rune telle tension révèle la forte influence de l'ancienneté du tourisme dans le lieu, de l'ancrage artistique, de l'histoire politique, religieuse et économique sur la définition de la nature et l'acceptation du tourisme dans chaque espace<br>During the 19 th century, the first protected areas in the Western world were created and had two missions to fulfil : environmental protection and promoting opportunities for enjoyment in order to welcome tourists. Since 1970 newly created protected areas have followed this double goal. The first 'Parc Naturel Régional' we studied from 2006 to 2008 had such goals but the relationship between the environmental protection goal and the tourism development goal was very tense. Tourists were seen as a threat, and managers had rather focusing on environmental protection. This thesis deals with three protected areas : the Lake District National Park (UK), the 'Espacio Natural de Doñana' (Spain) and the 'Parc Naturel Régional du Verdon' (France). What is at stake is the discovery of whether or not the tension is real between environmental protection and tourism in these areas. We aim at understanding in what way this tension can be felt and the reasons why these areas experience this tension (or not). After a content analysis showing that words used by managers were quite severe about tourists, we study the way the area is spatially ordered ,the relationships between actors, and statistics in tourism, revealing a total breaking off between the protected area, managers and tourists, whose practices are not understood nor accepted. The study of cultural and historical factors that can explain this tension shows a strong influence of the history of tourism,artistic heritage, political and economical history on the way nature is defined and the way tourism is accepted in each area

Abstract:
This thesis explores the embalming ritual of the Egyptian Late Period through Ptolemaic era (664 – 30 BC). Using an interdisciplinary approach, I incorporate primary and secondary texts, Egyptian funerary art and archaeological remains into my study. I utilize these lines of evidence to reconstruct the embalming ritual to the degree possible and analyze the ways in which its various stages were believed to fulfill the ultimate goal of this rite: preservation of the physical body and eternal life for the deceased. I focus particularly on the archaeological material and explore the visibility of religious practice in the archaeological record. I identify key changes and developments in the embalming ritual from the Late Period through the Ptolemaic Period in order to highlight religious significance placed on embalming during this time period. Funerary art, literature, and archaeological material of the Late through Greco-Roman Periods illustrate an increased focus on the integrity of the corpse as well as the manifestation of decay, the liquid \(rDw\). I examine these ancient sources in order to better understand the nature and development of body-centered funerary practices during this period of Egyptian history.
