This thesis contains descriptions and definitions of the Iron Age Proto-Aeolic capitals from Israel - Palestine area. The modern area, which my materials cover is Israel and Jordan. The time period of the capitals is between the 9th century BC and the late 8th or the beginning of the 7th century BC. Attention has been put on issues of typological characteristics, usage and time periods of the capitals and how this, through the new examples, described here for the first time, created a new typology and usage for the Proto-Aeolic capitals.

Al-Mg alloys were infiltrated into porous alumina preforms at temperatures greater than 950°C where significant amount of nitride forms in the matrix. The present work aims to obtain a process window for growing A1N rich composites over uniform thicknesses so that bulk fabrication of these composites could be carried out. Initial experiments were carried out in a thermo-gravimetric analyser (TGA) to establish suitable conditions for growing useful thicknesses. Al- 2wt% Mg alloy, alumina preforms of particle size 53-63μm and N2 - 2% H2 (5ppm O2) were used for the present study based on previous work carried out in the fabrication of MMCs at low temperatures. Experiments carried out in the TGA indicate that oxygen in the system has to be gettered for the growth of nitride rich composites. Infiltration heights of about 8mm were obtained using an external getter (Al - 5wt%Mg) alloy in addition to the base alloy used for infiltration. The above process conditions were subsequently employed in a tube furnace to fabricate bulk composites and to study the effect of temperature on the volume fraction of aluminium nitride in the matrix. The volume fraction of nitride in the composite varied between 30 and 95 vol % with increase in process temperature from 950°C to 1075°C. Microstructures of these composites indicate that A1N starts to form on the particle surface and tends to grow outwards. The metal supplied through channels adjacent to the particle surface nitride until a point is reached when the composite growing from the adjacent particles meet each other and isolate the melt underneath from nitrogen thereby leading to a metal rich region underneath. Increase in temperature results in an increased nitridation rate resulting in reduced metal pocket size. Composites fabricated at 975°C had a minor leak at the O-rings, which seal the tube. This led to infiltration under conditions of varying oxygen partial pressure leading to different nitride fractions in the composite. The above fact was confirmed by conducting an experiment with commercial purity nitrogen, which has an oxygen content of about 5000ppm. The composite had an A1N content of about 30% whereas the composite fabricated with N2 -2%H2 (5ppm oxygen) showed a nitride content of 64%. This suggests that one can vary the nitride content in the composite by varying the oxygen content in the system at a particular process temperature. The hardness of the matrix increases with increase in process temperature from 3.5 ± 0.7 GPa at 975°C to about 9.8 ± 0.9 GPa at 1075°C. Porosity was observed in the composite processed at 1075°C. This increased porosity leads to decreased hardness though the nitride content in the composite has increased by 11%. The scatter in the data is attributed to variations in the microstructure as well as due to interference from underlying metal pockets or particles as well as due to porosity introduced in the composite at high processing temperatures.

In 1974, after forty years of negotiations over the disputed sovereignty of the Al-Ain/Buraimi region, Zararah/Shaybah, and Khor al-Udaid, the governments of Saudi Arabia and the UAE signed the Treaty of Jeddah, apparently ending the dispute. But the dispute was not settled as far at the UAE was concerned, owing to discrepancies between the oral agreement before the Treaty’s signing and the final text of the Treaty itself. The UAE government did not notice this discrepancy until 1975, likely due to the absence of lawyers, technicians, and geographers on its negotiation team. The UAE has attempted to bring Saudi Arabia back to the negotiating table ever since. In 2004, thirty years after the Treaty was signed, the UAE launched a public diplomatic campaign to persuade Saudi Arabia to revisit parts of the Treaty, especially the question of the Zararah/Shaybah oil and gas field. The public campaign has had a detrimental affect on UAE-Saudi relations and the border dispute remains unresolved to this day. This thesis seeks to contribute to a better understanding of the Treaty of Jeddah by examining the negotiations that led to its signing on 21 August 1974, focusing on the period of 1970-74, about which relatively little has been written. It explains the process of negotiations, the context in which they took place, the role and influence of Britain (as Abu Dhabi’s protecting power up to 1971), why Abu Dhabi signed a treaty it quickly came to regret, the resulting aftermath, and how the UAE might yet obtain the Treaty’s revision. This thesis argues that Britain, as Abu Dhabi’s protecting power, played different roles through the negotiation process, and that Britain did not always negotiate in Abu Dhabi’s interests –– particularly during the final years of British protection (1968-71), when it increasingly advised Abu Dhabi to compromise. It shows how Abu Dhabi’s position weakened substantially after the withdrawal of British protection in 1971, while Saudi Arabia’s position was strengthened considerably by the US government’s Twin Pillar policy. It argues that Saudi Arabia maintained an inflexible position during 1970-74, when it adopted a ‘controlled negotiating strategy’ with aggressive tactics (including the threat of military intervention) designed to force Abu Dhabi into a corner, giving it no choice but to sign the Treaty. This approach allowed for a ‘win-lose’ outcome only. Indeed, there were no ‘negotiations’ as such –– the huge differences in power between Saudi Arabia and the UAE enabled the former to more or less impose a settlement on the latter. Finally, this thesis argues that the UAE’s claim to Khor al-Udaid, which is the most visible aspect of the dispute since it can be clearly shown on maps, is not in fact the most important issue for the UAE –– it is the oil and gas sharing arrangements in for Zararah/Shaybah oil field, due to their huge economic implications.

After the Catalan conflict in 2017, the number of female politicians and sympathizers in VOX increased notoriously(Bernardez-Rodal et al., 2020). Moreover, the growing participation and engagement of female audiences suggests that the use of several techniques to attract women (Pilkington, 2017; Mattheis, 2018; Askanius, 2021a) or the use of topics that evoque shared feelings (Dietze & Roth, 2020) could also be unfolding at a great speed in Spain. Thus, wanting to spand knowledge on the mentioned phenomenon, this thesis focuses on the Spanish context and explores how three VOX female politicians benefit from Alternative Influence Networks or AIN (Lewis, 2018) in Instagram and use influencer practices to spread far-righ ideas and sell anti-feminist or gender equality narratives.  For veracity and objectivity this research considered every post in the feed of these representatives for the sampling,obtaining a total of 290 relevant posts which were later analysed following a case study methodology. Theories of mediatization and media power, social media, online Interactivity and AIN, gender politics, and post-feminism and anti-feminism, served to understand the content of the analysed posts and classify them into 5 main topics (1. Anti-Feminism;2. Maternity; 3. Gender Politics and Gender Issues; 4. Targeting Women: Fear for the Spanish Race; 5. Christian values: pro-life and heteronormative love) that were repeatedly manifested in various ways. Main findings include how VOX female politicians benefit from social media to target women and sell far-right ideas through influencer practices and other tactics that are similarly used by other far-right actors. From this we could conclude that the role of female representators in VOX is of great importance to attract female audience by posting sensitive content or aiming at empathy through identification as well as to soften the image of the far-right through fear-based techniques or turning to biology.

L'utilisation de systèmes moléculaires individuels pouvant jouer le rôle de composants avec des fonctions électroniques ou logiques requiert des interfaces parfaitement contrôlées. Plus précisément, le support sur lequel ces systèmes sont déposés et les électrodes métalliques qui permettent de contacter une molécule individuelle, sont des interfaces qui nécessitent un soin d'élaboration particulier. La croissance d'îlots bidimensionnels (2d) de métaux sur un isolant monocristallin permet de générer des nano-plots 2d pouvant servir de réservoirs d'électrons en minimisant les courants de fuite en surface. Ainsi, il apparaît capital de bien comprendre les modes de croissance des systèmes métal/isolant qui sont à l'heure actuelle mal connus. Ce travail de thèse s'attache à décrire et à expliquer la croissance de différents métaux sur la surface de l'AlN(0001) polaire, qui est un composé nitrure à grand gap, par des calculs basés sur la théorie de la fonctionnelle de la densité (DFT).Dans un premier temps, une description approfondie des différentes surfaces du nitrure d'aluminium est présentée. Des calculs DFT ont permis de rationaliser les reconstructions en fonction des conditions expérimentales. La reconstruction (2 x 2)-Nad est discutée, puisqu'elle a été observée en microscopie à force atomique. Dans un deuxième temps, le cas du dépôt d'atomes d'or est abordé en connexion avec des résultats expérimentaux. Les calculs DFT donnent un aperçu des mécanismes qui conduisent à la stabilisation d'îlots 2d sur l'AlN. L'adsorption d'or s'accompagne, d'une part, d'un transfert de charge vertical provenant du substrat d'AlN, ce qui satisfait au critère de stabilité électrostatique pour un matériau polaire et, deuxièmement, par des transferts de charges horizontaux reliés aux propriétés acido-basiques locales de la reconstruction (2 x 2)-Nad. Enfin, des calculs effectués sur deux autres métaux, le magnésium et l'argent, sont exposés. Ces résultats ouvrent la voie à de nouvelles stratégies utilisant des substrats polaires pour développer des monocouches métalliques sur des substrats isolants. / The use of individual molecular systems that can act as components with electronic or logical functions requires perfectly controlled interfaces. More precisely, the support on which these systems are deposited and the metal electrodes that allow to contact an individual molecule, are interfaces that require special care in preparation. The growth of two-dimensional (2d) islands of metals on a monocrystalline insulator allows to generate 2d nano-pads that can be used as electron reservoirs by minimizing surface leakage currents. Thus, it is essential to understand the growth modes of metal/insulating systems which are at present poorly known. This work aims at describing and explaining the growth of different metals on the surface of the polar AlN (0001), which is a large gap nitride compound, by calculations based on density functional theory (DFT). In a first step, a detailed description of the various surfaces of the aluminum nitride is presented. DFT calculations permit to rationalize the reconstructions according to the experimental conditions. The (2 x 2)-Nad reconstruction is discussed, since it was observed by atomic force microscopy. In a second step, the case of the deposit of gold atoms is tackled in connection with experimental results. DFT calculations give an overview of the mechanisms that lead to the stabilization of 2d islands on AlN. The adsorption of gold is accompanied, on the one hand, by a vertical charge transfer from the AlN substrate, which satisfies the electrostatic stability criterion for a polar material and, on the other hand, by horizontal charge transfers related to the local acid-base properties of the (2 x 2)-Nad reconstruction. Finally, calculations made on two other metals, magnesium and silver, are exposed. These results open the way to new strategies using polar substrates to develop metallic monolayers on insulating substrates.

Dans un contexte de changement climatique, la compréhension du régime thermique des cours d’eau est un enjeu important. En mesurant le rayonnement dans le spectre électromagnétique de l’infrarouge thermique (IRT : 0,4-14µm), la télédétection IRT offre la possibilité d’obtenir une cartographie de la température de surface à différentes échelles spatiales. L’approche multi-échelle est ainsi le fil directeur de ce travail.Dans le premier temps, nous utilisons des images satellites Landsat ETM+ pour caractériser les structures thermiques longitudinales et temporelles d’un grand continuum fluvial : le Rhône français (500 km). Une méthode automatique supprimant les pixels contaminés par les entités exondées, est développée, améliorant ainsi la précision des données. Les images nous permettent de comprendre les effets thermiques des affluents et des centrales nucléaires. L’Isère est la principale source d’eau froide, alors que les centrales nucléaires du Bugey, de Saint-Alban et de Tricastin réchauffent le fleuve. Nous mettons en évidence des anomalies thermiques au niveau des aménagements hydroélectriques. Par rapport aux canaux, les Rhône court-circuités (RCC) sont plus sensibles aux conditions extérieures du fait de leur géométrie et de leurs conditions hydrauliques.Dans un second temps, les travaux se focalisent sur un tronçon plus court (50 km) : l’Ain dans sa basse vallée où quatre campagnes IRT aéroportées sont réalisées. Nous développons une méthode statistique permettant de calculer l’incertitude de mesure associée à la construction des profils longitudinaux de température de l’eau. Les artefacts des vraies tendances longitudinales sont ainsi différenciés. Pour comprendre ces tendances, un modèle 1D (thermo-hydraulique) est mis en place sur 21 kilomètres. Il considère les flux de chaleur à l’interface eau-air et les propriétés géométriques ainsi qu’hydrauliques de la rivière. Les arrivées phréatiques associées aux bras morts et aux suintements latéraux sont identifiées sur les images thermiques et intégrées au modèle. Ces arrivées phréatiques peuvent refroidir l’Ain de 0,6°C en été lorsqu’elles représentent 15,7% du débit total.Une échelle plus fine est explorée enfin. Le travail porte cette fois sur neuf tronçons en tresses (1 km) pour lesquels des images IRT à très haute résolution spatiale sont acquises. En caractérisant les distributions spatiales de la température, nous identifions deux types de tronçons. Le premier montre une très faible variabilité thermique spatiale tout au long de la journée. Les cours d’eau de ce type ont bien souvent un régime hydrologique proglaciaire avec des débits estivaux élevés, ce qui tend à homogénéiser la température. Le second type présente une hétérogénéité thermique élevée. La température des chenaux courants varie avec la température de l'air. En revanche, la température des chenaux alimentés par des eaux souterraines est relativement constante au cours de la journée. Nous proposons une méthode ne nécessitant pas d’images IRT pour identifier les tronçons montrant une variabilité thermique élevée.À travers ce travail, nous montrons qu’il est nécessaire de coupler les approches spatiales et temporelles pour comprendre la température des cours d’eau. Longtemps, les mesures ont été effectuées avec des thermomètres. L’aspect spatial a ainsi souvent été ignoré. La télédétection IRT a permit de mieux appréhender les structures spatiales de température. Toutefois, pour comprendre ces dernières il est indispensable de considérer les changements temporels de température. Il est également nécessaire d’intégrer une approche plus physique permettant de simuler différentes situations pour évaluer l’importance des différents facteurs affectant la température. / In a context of global warming, understanding the thermal regime of rivers is a key issue. By measuring the radiation in the electromagnetic spectrum of thermal infrared (TIR: 0.4-14µm), TIR remote sensing offers the possibility of obtaining surface temperature maps at multiple scales. The multi-scale approach is thus the guiding principle of this work.First we use satellite thermal infrared images from Landsat ETM+ to investigate longitudinal and temporal variations in the thermal patterns of a large river continuum, the French Rhône (500 km). An automated water extraction technique is developed to remove pixels contaminated by terrestrial surfaces. This method improves the accuracy of our data. The images allow us to understand the thermal effects of tributaries and nuclear power plants: the Isère is the main source of cold water while the Bugey, Saint-Alban and Tricastin nuclear power plants warm the river. We show temperature differences within the largest hydroelectric bypass facilities between the bypass section and the canal. The factors responsible for these differences are the length and minimum flow of the bypass section as well as tributaries coming into this reach.Second, we focus on a shorter river (50 km): the lower Ain in France where four airborne TIR surveys are performed. Based on a statistical analysis of temperature differences between overlapping images we calculate the measurement uncertainty associated with TIR derived profiles. This uncertainty allows for the discrimination between artifacts and real longitudinal thermal trends. To understand these trends, we use a 1D determinist model which predicts water temperature at an hourly time step along a 21 km reach. The model considers heat fluxes at the water-air interface as well as the geometrical and hydraulic characteristics of the river. Based on TIR images, groundwater inputs associated with backwaters and lateral seepages are identified. They are inserted into the temperature model. These groundwater inputs can mitigate high water temperatures during the summer by cooling the river up to -0.6°C when they represent 15.7% of the total discharge.A finer scale is finally explored. The work focuses on nine braided reaches located in the French Alps (1 km) where very high spatial resolution TIR images are acquired. By characterizing the spatial distributions of water temperature, we identify two types of reaches. The first type shows a very low thermal spatial variability throughout the day. Rivers of this type often have a proglacial hydrological regime with high summer flows, which tends to homogenize the temperature. The second type exhibits a higher thermal variability with changes during the day. The temperature of flowing channels changes during the daytime according to the air temperature. In contrast, the temperature of groundwater-fed channels exhibits smaller changes which creates thermal variability over space and time. We propose a method which does not require TIR images in order to identify reaches showing high thermal variability.Through this work, we show that it is essential to combine both spatial and temporal approaches to understand river temperature. Thermometers have been used for many years. Thus, the spatial aspect has often been ignored. TIR remote sensing has allowed a better characterization of spatial thermal patterns. However, to understand these patters it is necessary to consider temporal changes of water temperature. It is also necessary to integrate a more physical approach in order to simulate different scenarios and to assess the importance of the different factors affecting water temperature.

Doctor of Philosophy / Aim and significance: The aim of this research was to explore the phenomenon of Australian nursing home care from the perspective of those who provide and receive it. Its focus is on the processes of ‘quality care’ provision and the meanings and evaluations that care providers attach to their work. In other words, its purpose was to shed light on the practices based on a conceptualisation of care that is entwined with the mechanisms of ‘care’ production and identity creation, or what actually happens in the daily life of the complex social phenomenon that is a nursing home. A related aim was to add to understandings of clinical nursing competence and develop tools that will assist nurses to conceptualise and implement positive change in this setting. Background: The provision of care to our elderly has become a major concern with the ageing of the world population. This is occurring in the context of decline in the capacity of families to take on the responsibility of elder care, and of increasing commercialisation of medical care. Governments have responded by shifting their responsibilities from direct care provision to become auditors of the business of care provision that is supported by public funding. However poor care delivery has largely been hidden from the public gaze. Governments present themselves as having systems in place, creating the illusion of rational control; in reality, like the market economy, there is a ‘black box’ of unknown factors driven by human impulse. The aim of this study was to open up the black box of ‘quality care’ to direct observation, drawing insights from the literature on organisational culture and with a focus on the frontline worker and the construct of quality assurance. Specific research objectives were to: • Document the beliefs and attitudes of care providers towards elderly people in general and the needs of nursing home residents in particular • Elicit the range of meanings and evaluations that care providers attach to their work • Describe their constructions of ‘care’ and ‘quality of care’ and the organisational factors they believe to impact (positively and negatively) on their ability to provide it. • Through in-depth understanding of a particular setting, generate grounded theoretical insights into the phenomenon of quality of residential care that are more widely applicable Method: The study adopted a paradigmatic bricoleur approach, seeking to develop connections between a diverse range of methodologies. These included combinative ethnography, phenomenology, hermeneutics and traditional grounded theory. Conceptual insights were drawn from organisational studies, psychosocial nursing and coping theory. The research site was an Australian for-profit suburban nursing home. The student investigator conducted more than 500 hours of participant observation, recording extensive field notes which were analysed through the perspective of a hermeneutic middle way horizon that directed an augmented constant comparison traditional grounded theory approach. Additional data were collected through formal indepth interviews with six key stakeholders. Interviews were tape recorded, transcribed in full and analysed to reveal themes that were brought within a hermeneutic circle that spiralled recursively from the whole to the part and back to the whole. Findings: Eight key interrelated factors in the production of care within the nursing home were identified: internal and external accountability (the accreditation system); economic considerations; management and training; advocacy; characteristic of residents; care providers’ working conditions and environmental stressors; organisational culture; and the work/care styles of individual care providers. I have categorised the latter into two main types: ‘tortoises’ and ‘hares’. This typology is then used to generate a process-driven schematic diagram that tracks a hypothetical novice care provider through the process of learning how to produce ‘care’. Specifically, I found that nursing home ‘care’ is the outcome of a complex social process involving the interplay between resident, relative, care provider, proprietor, quality assessors and government within the phenomenon of the nursing home. Such care, indeed the phenomenon of the nursing home itself, is not a stable, controllable entity but is in a constant state of flux – what I refer to as a moral ecology. In their everyday practice, care providers devise a construction of ‘quality care’ that is more clearly grounded in their own worldviews and the development of the own identity than in the formal quality assurance system of standards, guidelines and evaluations. Conclusion: Understanding the ‘black box’ of processes that produce care is the key to identifying courses of action that will improve care outcomes. The study findings also question the validity, assumptions and significance of the accreditation system, which only identifies some of the component variables, disregarding both the complexity within the ‘black box’ and failing to acknowledge that the quality of care outcomes is overwhelmingly dependent on individual care providers.
