Rezente Korallenriffe sind einer ganzen Reihe von Bedrohungen ausgesetzt. Das Pleistozän bietet die Gelegenheit Veränderungen an Korallenriffgemeinschaften durch Klimaschwankungen hinweg zu studieren und mit heutigen Riffen zu vergleichen. Am besten sind pleistozäne Riffe in der Karibik untersucht, während aus dem Indo-Pazifik, der über eine deutlich höhere Biodiversität verfügt, bisher nur wenige quantitative Studien vorliegen. Frühere Studien zeigen eine erstaunliche Stabilität und Langlebigkeit der Korallengemeinschaften hinsichtlich Diversität und taxonomischer Zusammensetzung trotz extremer Meeresspiegelschwankungen und starker klimatischer Veränderungen im Quartär. Die vorliegende Arbeit behandelt zwei Regionen, aus der quantitative Daten auf Artniveau über die Zusammensetzung der fossilen Korallengemeinschaften bisher weitestgehend fehlten: das tropische Vanuatu (Südpazifik) und der subtropische Sinai, Ägypten (nördliches Rotes Meer). In Vanuatu sind mindestens 5 fossile Riffterrassen mit einem Alter von etwa 5000 - 400.000 Jahren überliefert, von denen 4 detailliert untersucht werden konnten. Veränderungen in der Diversität wurden sowohl lateral als auch vertikal nur mit unterschiedlichen Riffhabitaten in Verbindung gebracht. Die Riffe waren insgesamt über die Interglaziale bin ins mittlere Holozän hinweg stabil. Nur die Gattung Acropora scheint erst in den letzten 96.000 Jahren häufiger zu werden. In Ägypten wurden Daten aus der jüngsten interglazialen Terrasse (MIS 5e, ~125.000 Jahre) mit rezenten Daten aus dem Roten Meer verglichen und eine Migration von Arten nach Norden während des letzten Interglazials belegt. Diese Beobachtung unterstützt frühere Arbeiten, die eine Verschiebung der Riffdiversität in höhere Breiten verbunden mit einer Abnahme der Diversität in niederen Breiten aufzeigten, sowie Studien, die das nördliche Rote Meer als mögliches Refugium für Korallen im Zuge der weiteren Klimaerwärmung sehen. / The Pleistocene provides the opportunity to study changes of coral reef communities through times of climate change, and to compare fossil to recent reefs. Whereas Pleistocene reefs from the Caribbean are well studied and understood, the much larger Indo-Pacific region with a greater coral diversity is represented by only a few quantitative studies on community ecology. Previous studies observed an astonishing persistence and stability in community composition and diversity throughout several interglacial episodes until today, which is contradictory to the claim that recent coral reefs are especially sensitive to climate change. The present study deals with two Indo-Pacific regions that so far lacked quantitative data of fossil reef communities: tropical Vanuatu (Coral Sea) and subtropical Sinai, Egypt (northern Red Sea). In Vanuatu at least seven fossil reef terraces with ages between 5,000 and 400,000 years are preserved, of which four could be studied in more detail. A great variability was observed among terraces and especially among sub-environments within terraces. Reefs remained stable in terms of diversity throughout the Pleistocene and Holocene but it seems that the dominance of the coral genus Acropora is a fairly recent phenomenon in Vanuatu, because this genus does not play a large role in terraces older than 96,000 years (MIS 5c). In Egypt quantitative and binary data from the last interglacial episode (MIS 5e) were compared with data from the recent Red Sea and adjacent regions. These show a northward migration of coral taxa during the last MIS5e. This observation confirms earlier studies that demonstrated a range expansion of tropical reef communities towards higher latitudes, and supports studies that suggest the northern Red Sea and especially the Gulf of Aqaba as future refuge for corals during climate warming. These results indicate that coral reefs were able to cope with dramatic environmental changes in the absence of anthropogenic impact.

This study presents an overview of Indo-Soviet relations in light of the U.S.-U.S.S.R. competition for a favorable position in relations with India. Both superpowers consider better relations with India to be crucial to the furtherance of their interests in the Indian Ocean region. The study provides background information on Indo-Soviet diplomacy, with emphasis on the period 1968-1976m during which the Soviets gained their greatest influence in the region. This period also represents the nadir of Indo-American relations, although India formally maintained a policy of non-alignment with either of the two superpowers. Conclusions are drawn about India's role as a non-aligned nation, its relations with the superpowers, and its quest for regional influence.

Estudamos neste trabalho o comportamento da impureza oxigênio em rede cristalina de silício, usando primeiramente o método INDO (lntermediate Neglect of Differential Overlap) com parametrização espectroscópica e incluímos os efeitos de muitos elétrons via Método CI-(Interacão de Configuração). Fazemos uma análise sobre as possíveis origens do posicionamento não-central (off-center) dessa impureza, - se decorrente de uma distorsão Pseudo Jahn-Teller: - se originária de um CR Reconstrução Química. Quando o átomo de Oxigênio é deslocado ao longo da direção [100] ocupa um sitio de mínimo absoluto. O oxigênio introduz no gap de banda um orbital anti-ligante de simetria a1 totalmente ocupado, situação semelhante à dos anti-sitios em materiais semi-condutores III-V. Estudamos também o comportamento dessa impureza quando a mesma é deslocada ao longo da direção [111], verificando que é criada uma posição de Instabilidade mas, os auto-valores têm comportamento não esperado para orbitais anti-ligantes. / In this work we studied the Oxygen impurity in Silicon. The calculations were performed using a semi-empirical method (INDO/S) with Configuration Interaction to account for many-electron effects. We analyse the origin of the off-center position for substitutional oxygen. Pseudo Jahn-Teller distortion or Chemical Rebonding effects. The oxygen introduces an a1 anti-bonding state in the forbidden band-gap similar to anti-site defects in III-V materials. To answer the question about distortion, we also studied oxygen dislocation in the (111) direction and we obtained a metastable state but his eigen-value has a non-expected behavior for anti-bonding orbitals.

Mon travail de recherche consiste à comparer les formes du merveilleux dans deux oeuvres, génériquement, culturellement et linguistiquement tout à fait distinctes et qui pourtant ne sont pas sans liens. Le roman de Jaufré est un roman arthurien écrit en occitan probablement au début du XIIIème siècle, tandis que les Narty Kaddžytæ sont le trésor dupeuple ossète, légendes recueillies aux XIXème et XXème siècles auprès des conteurs (kadæggændžytæ) et publiées notamment par des savants tels que Vs. Miller et V.I. Abaev. G. Dumézil a montré combien le cycle des Nartes, bien que rapporté par la tradition orale, s’enracinait très profondément dans le passé au-delà du peuple ossète lui-même. Dansles légendes de ce petit peuple, dernier locuteur d’une langue nord-est iranienne (la branche scythique), on retrouve maintes accointances avec les coutumes et croyances des Scythes, tels que décrits par Hérodote. [etc.] / My research concentrates on the comparison of the shapes taken by ‘merveilleux’ motives in two works truly different as far as literary genres, cultural and linguistic backgrounds are concerned, and yet not totally lacking connections.The roman de Jaufré is an Arthurian romance written in Occitan, probably from the beginning of the XIIIth century, while the Narty Kaddžytæ (Nart legends) are the treasure of Ossetian people, legends collected during the XIXth and XXth centuries from kadæggændžytæ (oral storytellers), and published by Russian, Ossetian or European scholars such as Vs. Miller, V.I. Abaev. Miller and later Dumézil proved how the Nart Legends, though coming from oral tradition, was rooted in a past far beyond the ethnogenesis of the Ossetian people. A lot of striking connections are to be found between the epic of these people - last speakers of a language from the Northeast Iranian group (or Scythian branch) - and the habits or the faith ofthe Scythian people, such as Herodote described them.

Le croisement des sources écrites permet de restituer des confins parthes comprenant la Margiane, l’Arie, la Drangiane, l’Arachosie, une partie de la Bactriane et la vallée de l’Indus. La rareté et l’ambiguïté des sources avaient fait négliger les indications sur la Bactriane et envisager l’indépendance des autres régions à partir du Ier siècle de notre ère. Les récents renouvellements de la documentation, en particulier numismatique et archéologique, concernant l’Asie centrale et le nord-ouest de l’Inde, et les progrès accomplis par la critique des sources permettent aujourd’hui de reconsidérer la question. L’objectif de notre enquête consiste à explorer l’hypothèse d’une intégration politique de cet espace à l’empire parthe, occupé en partie par des populations réputées scythes et dont les pratiques monétaires sont habituellement interprétées comme le témoignage d’une indépendance politique. La reconstitution d’un corpus adéquat, la relecture critique des sources écrites et la reconsidération du matériel disponible montrent que la réinterprétation des données permet d’intégrer celles-ci de façon plus cohérente dans une synthèse d’ensemble enrichie. Cette étude, en faisant intervenir des « Sakas-Parthes » de Bactriane, des Parthes « scythisés » de Margiane et des « Indo-Sako-Parthes » dans les régions sud-orientales, veut montrer que la question de l’origine ethnique est de peu d’intérêt pour rendre compte de la culture et des pratiques politiques de groupes que leur position géographique frontalière vouait à avoir un peuplement ethniquement mêlé et à subir de puissants effets d’acculturation communs aux pays voisins et constamment renouvelés. / Intersecting written sources allows a restitution of Parthian eastern borders comprising Margiana, Aria, Drangiana, Arachosia, one part of Bactria, and the Indus Valley. The rarity and the ambiguity of sources had caused us to neglect the indications pertaining to Bactria and to envision the independence of the other regions from the 1st century of our era. The recent revival of sources -- in particular numismatic and archeological ones -- concerning central Asia and north-west India, as well as the progress accomplished by the criticism of sources allow us today to reconsider this statement. Our investigation aims at exploring the hypothesis of a political integration of these regions to the Parthian Empire, partly occupied by populations known as Scythian, whose monetary practices are usually interpreted as a mark of political independence. The reconstitution of an adequate corpus, the critical re-evaluation of the written sources, as well as the reconsideration of the available material allow us to reinterpret the data and to integrate them in a more consistent way within an overall improved synthesis. This study involves so called Bactrian 'Saka-Parthians', Margian 'scythianized Parthians' and south-oriental 'Indo-sako-Parthians'; it seeks to demonstrate that the issue of ethnical origin is of little interest to understand the cultural and political practices of these groups, which, due to their geographical position on the frontier, were doomed to have an ethnically mixed population and to undergo powerful acculturation effects which were common to neighbouring countries and which where constantly renewed.

This thesis concerns languages in the Greater Hindukush, the area in northern Afghanistan and Pakistan, where a total of about 50 languages are spoken. The thesis’ topic is case systems and case alignment systems of nouns in an areal-typological perspective. This is investigated by using a representative sample. The grammatical relations of S, A and P, and the cases marking these, are investigated. The three attested alignment systems are accusative, ergative and split, and are clearly geogra-phically distributed, which indicates that their status is areal-typological. Based on the sample, there seems to be a tendency for the languages in the Greater Hindukush to exhibit split align-ment systems built on tense-aspect. Most languages employ accusative alignment in imperfect-tive, and ergative alignment in perfective tense-aspects. A compa­rison with a worldwide sample (WALS) is only partly possible, as this sample uses more categories than accusative, ergative and split, but the present sample supports the results in those categories which can be compared. A predominant pattern in core case syncretism is observed, with an opposition of the nomi­native singular versus the nominative plural and the oblique in both numbers. / Denna uppsats behandlar språk i Hindukush i norra Afghanistan och Pakistan, där sammanlagt ca 50 språk talas. Ämnet för studien är kasussystem och kasusmarkeringssystem vid substantiv ur ett areal­typologiskt perspektiv, vilket undersöks utifrån grammatikor i ett representativt urval av språken. De grammatiska relationerna mellan S, A och P och de kasus som markerar dessa under­­söks. Belagda kasusmarkeringssystem är ackusativ- och ergativsystem samt kluvet system. Systemen uppvisar en distinkt geografisk distribution, vilket antyder att kasusmarkeringssystemen är ett arealtypologiskt drag. Vidare pekar resultaten på ett kluvet system baserat på klyvning i tempus-aspekt som det dominerande kasusmarkeringssystemet i Hindukush. De flesta av språken använder ett ackusativt kasusmarkeringssystem i imperfektiva, och ett ergativt kasusmarke-ringssystem i perfektiva tempus-aspekt. En jämförelse med ett globalt sampel (WALS) är bara till viss del möjlig, eftersom studien i WALS använder fler kategorier än ackusativa, ergativa och kluvna system, men den här studien bekräftar resultaten i de kategorier som kan jämföras. Ett dominerande mönster för kärnkasussynkretism kan observeras, med sammanfall av nominativ plural och oblik i båda numerus. / Språkkontakt och språksläktskap i Hindukushregionen, Vetenskapsrådet, Projektnummer: 421-2014-631

L'objet de cette thèse est de montrer en quoi l'Énéide constitue le récit de l'initiation royale d'Énée sous le patronage de Diane, la déesse latine de la souveraineté. L'épopée révèle sa dimension initiatique à travers sa triplicité - narrative et fonctionnelle -, en accord avec la théologie de la déesse initiatique, elle-même triple et trifonctionnelle. Chacun des niveaux fonctionnels de Diane est incarné par l'une de ses servantes : Didon (troisième fonction), la Sibylle (première fonction),Camille (deuxième fonction). Subissant les épreuves rencontrées dans les domaines sauvages et marginaux dont elles sont - au moins symboliquement - les maîtresses (Carthage, Cumes, le Latium), Énée se qualifie comme initié dans chaque fonction, ce qui lui permet d'accéder au statut d'être complet, trifonctionnel, idéal du roi indo-européen. / The purpose of this thesis is to show how the Aeneid constitutes the account of the royal initiation of Aeneas under the patronage of Diana, the Latin goddess of sovereignty. The epic reveals its initiatory dimension through its narrative and functional triplicity, in accordance with the theology of the initiatory goddess, triple and trifunctional herself. Each of Diana's functional levels is embodied by one of her servants: Dido (third function), the Sibyl (first function), Camilla (second function). Subjected to the trials in the wild and marginal areas of which they are - at least symbolically - the mistresses (Carthage, Cumae, Latium), Aeneas qualifies as an initiate in every function, which allows him to access to the status of complete, trifunctional being, the ideal of the lndo-European king.

The south coast of South Africa represents the extreme western end of the range of the Indo-Pacific humpback (Sousa chinensis, plumbea type) and Indo-Pacific bottlenose dolphins (Tursiops aduncus), which are both confirmed to range as far west as False Bay (Jefferson & Karczmarski, 2001; Hammond et al., 2008). Individual ranging behaviour for both species however is not well resolved. Recent genetic analyses suggest that animals currently considered as plumbea type Sousa chinensis (Reeves et al., 2008) may be a separate species, Sousa plumbea (Mendez et al., 2013). In South African waters less than 1000 adult humpback dolphins (Sousa chinensis, plumbea type hereafter “humpback dolphin”) may comprise the entire population (Karczmarski, 1996), while all estimates suggest the bottlenose dolphin (Tursiops aduncus, hereafter “bottlenose dolphins”) population is relatively large, numbering thousands of animals (Cockcroft et al., 1992; Reisinger & Karczmarski, 2010). Both dolphin species are exposed to variable levels of anthropogenic impacts throughout their range including vessel traffic, chemical pollution and habitat degradation associated with coastal development. This thesis describes the results of a study investigating: 1) the environmental and anthropogenic factors which influence the habitat use of humpback and bottlenose dolphins in two adjacent bays on the southern Cape coast, South Africa – Mossel Bay and Vlees Bay; 2) the abundance of humpback dolphins using Mossel Bay and 3) the interaction of these two dolphin species with white sharks, and the influence this has on dolphin group sizes and habitat use in Mossel Bay. Both land-based and boat-based survey platforms were used in this study with land-based data collected during dedicated watch periods at sites in Mossel Bay (n = 6) and Vlees Bay (n = 4) between February 2011 and March 2013, with a focus on humpback and bottlenose dolphins. A surveyor’s theodolite was used at these sites to collect positional data on animals, while behavioural data were collected through direct observation. Boat-based photographic identification surveys were used to collect data on the presence of individual humpback dolphins in Mossel Bay between April 2011 and November 2013. White shark data from Mossel Bay between February 2011 and March 2013 were provided from boat-based chumming surveys for the collection of photo-ID data from the Master’s thesis of Rabi’a Ryklief, based at Oceans Research. Data were analysed using ANOVA’s, Tukey honest significance tests and generalised additive modelling (Wood, 2006) in programme R, while capture histories of humpback dolphins were analysed with RMark (Laake, 2013) using POPAN open population models (Schwarz & Arnason, 1996) and Huggins heterogeneity closed capture models (Huggins, 1989; Chao et al., 1992). Humpback dolphins socialised over sandy beach habitats in both bays, while feeding/foraging occurred over reef systems in Mossel Bay and off fine grained sandy beach habitats in Vlees Bay. Humpback dolphin resting behaviour was observed at a very low frequency and occurred in all of the primary habitat types in Mossel Bay, while in Vlees Bay resting was only observed over reefs. Bottlenose dolphins in both bays preferentially used wave cut rocky platform habitats for feeding/foraging and resting while socialising occurred in the vicinity of estuaries in Mossel Bay and fine grained sandy beach habitats in Vlees Bay. Higher sighting rates were recorded in the control site, Vlees Bay, than in Mossel Bay for both dolphin species. The largest reverse osmosis desalination plant commenced operations in the sheltered corner of Mossel Bay in October 2011 and discharged approximately five million litres (Ml) of effluent per day (between October 2011 and February 2012) and 18 Ml per day in March and April 2012. In Mossel Bay higher sighting rates of humpback dolphins occurred in the period before desalination began while bottlenose dolphin sighting rates were highest after active desalination decreased to once per month (May, 2012). During the period of peak brine discharge in Mossel Bay, sighting rates were highest for both species in Vlees Bay. Even after desalination operations decreased the sighting rate of humpback dolphins remained low. The operation of the desalination plant at full capacity in Mossel Bay may have led to reduced use of this area by both humpback and bottlenose dolphins. Key habitats in Mossel Bay for both dolphin species are shared with great white sharks (Carcharodon carcharias hereafter “white sharks”) and focus around the three estuaries and their associated near-shore reef systems. The presence of predatory white sharks may limit the time dolphins spend in a specific habitat and influence the number of animals within groups, with larger humpback dolphin groups at sites with high shark utilisation. Both dolphin species had lower individual sighting rates during periods when white shark abundance peaked. Large group sizes of humpback dolphins at Seal Island, and of bottlenose dolphins at Hartenbos and Tergniet, combined with increased rates of travelling and decreased resting and socializing suggest that these areas may pose the largest threat to dolphins due to the variety of shark size classes’ present, especially larger sharks. Closed capture models generated within year population estimates ranging from 48 to 97 individual humpback dolphins (2011: 97, 95% CI: 46 – 205; 2012: 48, 28 – 81; 2013: 68, 35 – 131) while open population modelling produced a ‘super-population’ estimate of 116 animals (95% CI: 54 – 247) using Mossel Bay. During the study 67 humpback dolphins were individually identified with 94.3 % of the individuals in good quality photographs distinctively marked. Fewer humpback dolphins may be present on the south-east and southern Cape coast, including between Algoa Bay and Mossel Bay, than initially thought (Karczmarski, 1996), as definite links exist between Algoa Bay and Plettenberg Bay (Smith-Goodwin, 1997), and Plettenberg Bay and Mossel Bay (this study). The Gouritz River mouth (21º 53' E; Ross, 1984) and De Hoop (20º 30' E; Findlay et al., 1992) were previous suggested as the western limit of this species, but within the last 20 years knowledge on the extent of their range has been greatly improved, and range extension of this species may be occurring to the west with animals present as far west as False Bay (18º 48' E; Jefferson & Karczmarski, 2001). Due to the vulnerability of this species and their wide ranging behaviour, conservation plans need to be implemented on a wide scale to ensure protection of these animals from human impacts throughout their range. A concerted effort is required to further establish the population links between the various locations on the southern Cape coast that these animals frequent. / Dissertation (MSc)--University of Pretoria, 2014. / Zoology and Entomology / MSc / Unrestricted

Ce travail avait pour but de reconstituer l'évolution de la température et du δ¹⁸O des eaux de surface et des eaux de la thermocline dans la Warmpool indo-pacifique (IPWP) en combinant la thermométrie Mg / Ca et la mesure des isotopes stables de l'oxygène sur des foraminifères planctoniques de surface et de sub-surface prélevés dans des carottes de sédiments situées dans l'océan Indien tropical oriental. Ce travail a permis de ré-évaluer les effets des différentes méthodes de nettoyage et de la dissolution in situ sur la thermométrie Mg/Ca des foraminifères planctoniques, mettant en évidence la nécessité de corrections différentes suivant les espèces. L’évolution de l’IPWP au cours des 270 000 dernières années a été reconstituée. Les résultats indiquent que le δ¹⁸O des eaux de surface reflètent principalement l'advection latérale plutôt que l'historique des précipitations régionales, et suggèrent que l'hydrologie de surface IPWP est contrôlée par la migration latitudinale de la zone de convergence intertropicale aux échelles de temps orbitales mais aussi en réponse aux événements climatiques abrupts de l'hémisphère nord (eg. événements de Heinrich). Les variations de salinité de surface sont étroitement corrélées aux changements d’export vers l’Atlantique au niveau du Courant des Aiguilles (Sud de l’Afrique). Puis, les changements dans le transport des eaux de la thermocline issues de l’ITF vers l'océan Indien ont été étudiés. Les résultats montrent que le transport était plus faible pendant les glaciations (ie. MIS 6 et 4-2) que pendant les périodes interglaciaires (ie. MIS 7, MIS 5 et Holocène) et exerçaient une influence significative sur les changements de la température de la thermocline dans l'Océan Indien. / This work aimed at reconstructing the late Quaternary evolution of surface and thermocline temperature and ocean surface water δ¹⁸O in the Indo-Pacific Warm Pool by combining Mg/Ca-thermometry and stable oxygen isotope analyses on surface and thermocline-dwelling planktonic foraminifers retrieved from sediment cores in the eastern tropical Indian Ocean. This study allowed to re-evaluate the effects of different cleaning methods and in-situ dissolution on the Mg-thermometry of planktonic foraminifers, evidencing the need for species-dependent corrections. Then, the IPWP evolution over the last 270,000 years has been explored. Results indicate that surface water δ¹⁸O chiefly reflects lateral advection rather than local precipitation history, and suggest that surface IPWP hydrology is controlled by the latitudinal migration of the Intertropical Convergence Zone at orbital timescale as well as during abrupt northern hemisphere climatic events (i.e. Heinrich events). Ocean surface salinity in the IPWP and Agulhas leakage region varied synchronously, implying their teleconnection through oceanic and atmospheric circulation. Moreover, changes in the transport of thermocline water to the Indian Ocean by the Indonesian Throughflow (ITF) have been reconstructed. Results show that thermocline water transport was weaker during glacials (i.e. MIS 6 and 4-2) than during interglacials (MIS 7, MIS 5 and Holocene), and exerted significant influence on Indian Ocean TWT change.

In this study we will attempt to discover the background of [apostolos] among its pagan ancestors. In addition to this area, we will also be concerned with the Jewish background which exerted a formative influence on the meaning of the word. Finally, an attempt will be made to see the result of this combination of backgrounds as it came to be reflected in the New Testament.
