This thesis explores the ‘credibility' of news in Saudi Arabia, comparing online media with official newspapers. The latter are heavily regulated offering limited viewpoints. But the Saudi government has been less able to regulate online. Against a historical background of news development in Saudi Arabia, the thesis explores the rise of online from discussion forums established in the 1990s to online newspapers and social media. Largely qualitative methods (interviews, focus groups) plus a quantitative survey, were adopted to collect two sets of data: from educated readers, and from journalists working for online publications. Additionally, material from two news case studies was gathered. Questions concerned: how online news was evaluated by users compared to more traditional reporting; how producers perceived the distinctiveness of online titles and the issues they faced. The data from the case studies – an ‘internal' news story, Corona virus and an ‘external' event, Egyptian elections – was subjected to ‘frame' analysis, addressing the different news coverage of official print titles, online news and independent Twitter accounts. Focus was on whether online reporting offered more varied viewpoints and greater reader participation, and whether there was evidence for more management of news by the Saudi authorities in relation to the internal as compared to the external news event. The thesis argues that compared to official newspapers, online titles have largely gained greater credibility amongst educated Saudi users. They are regarded as offering different views, more ‘objective' reporting and actively encourage reader comment. Findings indicate that online is less censored than official newspapers, but editors/journalists have learnt the skills of self-censorship to avoid blocking. Exchange of views on Twitter also demonstrate the possibility of distinctive voices and viewpoints being aired and argued over. In these ways, the relation between online news and readers/users begins to enable the formation of independent ‘public opinion'.

This thesis attempts to explain the change in Turkey’s foreign policy regarding Cyprus between 2002 and 2004. It argues that the overriding factor in this policy change was a change in leadership, i.e., the coming to power of the Justice and Development Party (AKP), which developed a decidedly liberal outlook on foreign affairs following its split in 2001 from the anti-Western, Islamist Welfare Party. Other crucial determinants included the Europeanization of the Cyprus issue and selective support for interest groups within Turkey, both of which were affected to various degrees by the European Union and a propitious change in decision-making context. This thesis shows how constant policy failures during the 1980s and 1990s led to an identity crisis and the subsequent radical ideational transformation of the AKP whereby the party leadership renounced political Islamism and began to espouse an EU-oriented policy agenda and compatible rhetoric. The arguments presented in this thesis contribute to the literature on foreign policy analysis, political leadership and Europeanization. With regard to foreign policy analysis, this thesis shows that foreign policy change is a multi-causal phenomenon that can only be explained by a combination of various concepts. Moreover, it argues that despite the fact that no ready-made formula can account for all cases of foreign policy alterations, changes in leadership and a favourable decision-making composition appear to be indispensable determinants of any foreign policy shift. With regard to leadership, by applying a social-learning model to the analysis of the AKP leadership, this thesis follows the evolution of the Turkish Islamist Movement towards conservative democracy and an embracing of EU norms, which in turn resulted in a change in Turkey’s Cyprus policy. It is argued that Turkey’s new Cyprus policy was above all the consequence of a radical normative shift in the mindset of the new Turkish leadership. With regard to Europeanization, this thesis demonstrates how the change in Turkey’s foreign policy vis-à-vis Cyprus was bolstered by the Europeanization process. In this context, it can be understood that the EU militated in favour of a policy alteration by Europeanizing the Cyprus disagreement with the acceptance of the Republic of Cyprus into the EU in May 2004. The third essential determinant of Turkish foreign policy shift was the emergence of a propitious decision-making context within Turkey, which rendered such a policy shift possible.

O papel da Península Ibérica na Antiguidade tem sido debatido constantemente na historiografia internacional e também pela brasileira. Este trabalho tem como norte analisar a presença nas fontes escritas da Antiguidade do reino de Tartessos e do rei Argantônio. Desta maneira, buscaremos, com base nas obras de Historias, de Heródoto, Geografia de Ibéria, de Estrabão e Orla Marítima, de Avieno investigar algumas questões pertinentes à natureza do reino de Tartessos e como estes pontos nos ajudam a compreender, também, as características da Península Ibérica no período pré-romano. O Objeto de Aprendizagem que acompanha esta pesquisa e que foi desenvolvido durante o Programa de Pós-Graduação em História Ibérica trata-se de um jogo digital chamado Deuses do Tempo. Conta a história de três arqueólogos que são jogados em vários períodos do passado por enfurecer uma divindade. Para voltar ao seu tempo de origem, devem cumprir algumas tarefas. / The role of the Iberian Peninsula in antiquity has been constantly debated in international and also Brazilian historiography. This research analyzes the presence in the written sources of Antiquity of the kingdom of Tartessos and the king Argantônio. In this way, we will seek, based on the works of Herodotus (History), Strabo, (Geography of Iberia) and Avieno (Ora Maritma), an investigate some questions pertinent to the nature of the kingdom of Tartessos and how these points help us to understand, also, the characteristics of the Iberian Peninsula in the pre-Roman period. The Learning Object that accompanies this research and was developed during the Post-Graduate Program in Iberian History is a digital game called Gods of Time. It tells a story of three archaeologists who have been thrown in various periods of the past by infuriating a deity. To get back to their source time, they must complete some tasks.

Este trabalho se propõe a analisar a Ordem de Cristo, herdeira da Ordem Templária. Esta última foi “extinta”, devido ter adquirido muito poder e riqueza. Compreender a transição da Ordem Templária para a Ordem de Cristo, e a relação dessas duas ordens com a Igreja Católica e com a monarquia portuguesa é fundamental para contextualização da expansão marítima portuguesa e compreensão do êxito obtido por Portugal nas navegações e descobrimentos territoriais. O elemento religioso foi fator decisivo para a criação destas duas Ordens, a Ordem Templária; criada para combater os muçulmanos no Oriente e a Ordem de Cristo; para combater os muçulmanos em Portugal. D. Dinis rei de Portugal no início do século XIV conseguiu realizar uma manobra estratégica quando obteve autorização papal para criar a Ordem de Cristo, que se tornou ao longo dos séculos o cerne da expansão territorial portuguesa além – mar. A presente pesquisa não se restringe apenas a confecção da dissertação de mestrado para a obtenção do título de mestre, desenvolvemos um objeto de aprendizagem virtual composto por dois itens: história em quadrinhos no formato PDF desenvolvido através da Plataforma Pixton e um quiz no formato HTML elaborado através do Freeware Hot Potatoes atendendo as normas do Programa de Pós - graduação em História Ibérica - PPGHI da Universidade Federal de Alfenas/MG disponibilizando-o ao programa no final da pesquisa. / This work proposes to analyze the Order of Christ, heiress of the Templar Order. This last one was "extinct", due to having acquired much power and wealth. Understanding the transition from the Templar Order to the Order of Christ, and the relationship of these two orders with the Catholic Church and the Portuguese monarchy is fundamental for the contextualization of the Portuguese maritime expansion and understanding of the success achieved by Portugal in territorial navigations and discoveries. The religious element was decisive factor for the creation of these two Orders, the Templar Order; created to fight the Muslims in the East and the Order of Christ; to combat Muslims in Portugal. Dinis king of Portugal in the beginning of the fourteenth century was able to carry out a strategic maneuver when he obtained papal authorization to create the Order of Christ, which became over the centuries the core of Portuguese territorial expansion overseas. The present research is not restricted to the preparation of the master's dissertation to obtain the title of master, we developed a virtual learning object composed of two items: comic book in PDF format developed through the Pixton Platform and a quiz in HTML format elaborated through the Freeware Hot Potatoes meeting the norms of the Postgraduate Program in Iberian History - PPGHI of the Federal University of Alfenas / MG making it available to the program at the end of the research.

Understanding of the economic processes shaping regional economies is in a constant state of change. These processes are important to understand for policy making as governments seek to improve the economic well-being of citizens. Existing empirical research in this field has focussed on regions in economically advanced and technologically innovative economies. As a consequence, the broader picture of the dynamics of regional development in less developed countries, particularly its social and political origins and the overall changes in regional inequality, have remained elusive and less clear. The purpose of this thesis has been to develop an understanding of the local and regional dynamics of economic development in the context of the transitioning and emerging economy of Turkey. The approach has been to unpack a series of local and regional development theories and, from the drivers identified, to develop an econometric model calibrated for the Turkish context using available and appropriate proxy measures. Document analysis supported by interviews with groups of policy makers has been intertwined with the results of the model. The results of the study explain that implications of the current local and regional economic development theories are a Curate’s Egg – good in parts – because these theories are only partially relevant in the Turkish context.

This dissertation research is a bioarchaeological investigation of Late Neolithic through Early Bronze Age (3600-1800 BC) burial populations from the Portuguese Estremadura. In this project macroscopic and isotopic analyses of skeletal and dental materials are used to gather information pertaining to diet, health status, and inter-lifetime mobility patterns for individuals interred at different burials within a small geographic area with the goal of evaluating the level of social differentiation in the region. The archaeological record for the transition between the Late Neolithic and the Early Bronze Age in southwestern Portugal demonstrates clear evidence of the rise of a socially-complex, non-state society. During the Early Bronze Age, however, this region underwent a period of social `devolution' which cumulated in widespread settlement abandonment. To date, it is unclear to what extent sociopolitical or environmental factors contributed to this social collapse. This study seeks to expand our knowledge of social differentiation in the Late Neolithic to Early Bronze Age of the Estremadura region of Portugal and provide insight into social structure during the emergence and collapse of early complex societies in Iberia. The results of this study found that there were statistically significant differences in dietary, mobility and demographic patterns between burials that suggest socially distinct populations were interred at different sites. In particular, one burial site, Cova da Moura, diverged significantly from the other sampled burial populations. However, based upon the data presented here, it was not possible to tie these biological markers of differentiation to particular aspects of Late Neolithic to Early Bronze Age social organization. Therefore, while this study successfully identified differences between burial populations, at this time, it is not possibly to relate these to particular hierarchical structures. It is suggested that aspects of burial practices in the region confound biologically-based investigations of social organization in a similar way that they have impeded researchers' abilities to identify elite versus non-elite individuals through grave goods alone. Nonetheless, despite these obstacles, this work provides strong evidence of population heterogeneity in the region, and has implications for our understanding of the evolution of complex societies in the Iberian Peninsula and elsewhere.

Este trabajo supone un estudio y análisis, así como una transcripción semipaleográfica, del manuscrito inédito P.iii.21 de la Biblioteca del Real Monasterio de San Lorenzo de El Escorial, que contiene una copia del Libro declarante o el Libro de las tres creencias, una obra generalmente atribuida al converso castellano Abner de Burgos y que se cree se redactó a mediados del siglo XIV. Consiste de dos partes principales: Una introducción crítica donde se analizan la estructura y el propósito del Libro, así como varios temas que todavía generan controversia y a los que no se ha llegado a dar una respuesta definitiva, como lo son la autoría del Libro y el posible propósito del autor al redactar esta obra. Se comparan estrategias retóricas utilizadas a través del Libro con las estrategias que se usan en otras obras de Abner de Burgos para, así, poder ampliar el campo de argumentación con nuevas evidencias que apoyen la atribución del Libro a Abner. La segunda parte es una transcripción semipaleográfica del contenido del manuscrito escurialense P.iii.21 con anotaciones al margen y referencias en hebreo a los pasajes transliterados del hebreo al alfabeto latino que se encuentran a través de este manuscrito. Se ha intentado emparejar los pasajes bíblicos en latín con el pasaje correspondiente en la Vulgata, y también se ha tratado de identificar las fuentes utilizadas en el texto que quedan fuera de la Biblia hebrea y el Nuevo Testamento. Como marco de referencia, en la primera parte de este trabajo se ofrece una breve introducción biográfica a la figura histórica de Abner de Burgos y la influencia que ejerció en la literatura polemista, tanto judía como castellana. También se incluye una breve introducción a la relación entre Abner, el Libro y los estilos de argumentación que eran populares en la Península Ibérica en los siglos XIII y XIV.

It is widely known that the world is losing biodiversity and primarily it is thought to be caused by anthropogenic activities. Many of these activities have been identified. However, we still lack a clear understanding of the causal relationships between human activities and the pressures they place on the environment and biodiversity. We need to know how ecosystems and individual species respond to changes in human activities and therefore how best to moderate our actions and reduce the rate of loss of biodiversity. One of the ways to detect these changes is to use indicators of ecosystem conditions. Indicators are statistics following changes in a particular factor usually over time. These indicators are used to summarise a complex set of data, and are seen as being representative of the wider situation in that field. So it can be assumed that if that particular factor is declining or improving, then the situation in general is also declining or improving. They are used to check the status and trends of biodiversity by both the public and policy makers. Indicators are also used to assess national performance and can be used to identify the actions required at the policy level. In this manner, they provide an important link between policy-makers and scientists collecting the data. The current thesis investigates the possibility of using bird species as indicators of biodiversity for better management of natural terrestrial ecosystems, by identifying their habitats according to various environmental factors. The study is established by drawing upon three main scientific areas: ecology, geographical information system (GIS), and statistical modelling. The Mornington Peninsula and Western Port Biosphere Reserve (MPWPBR) (Victoria, Australia) was chosen for the study area because of the combination of suburban and natural environments that made it optimum for this type of study. Once the study area was defined, the necessary data for the research were obtained from various sources. Birds Australia provided data on recorded observation of 271 bird species within the study area. Based on the nature of this study, seven species were selected for the study. The criteria for this selection are discussed in Chapter 3. Most literature state that the primary determinant for bird abundance is vegetation and land cover. Because of this, Ecological Vegetation Class (EVC) layer was used to determine which type(s) of vegetation have the greatest impact on habitat selection. Each species showed a relationship to a number of v vegetation types. These EVCs were combined to produce vegetation patches, and were considered as potentially suitable habitats of corresponding bird species. For each of the species, these habitat patches were analysed for the different aspects of patch characteristics (such as the level of patchiness, connectivity, size, shape, weighted distance between patches, etc.) by using the Landscape Context Tool (a GIS add-on). This process assisted the understanding of the importance of patch quality in habitat selection among different bird species by analysing the location of bird observation sites relative to habitat patches. In this way, the association between bird presence and the conditions of a habitat patch was identified by performing a discriminant function analysis. To investigate the probability of a species presence according to different environmental factors, a model of species distribution was created. Binary logistic regression was used to indicate the level of effect of each variable. The model was then successfully validated in the field. To define the indicators of environmental factors, it was essential to separate bird species based on their dependency on one or more of the studied variables. For this purpose, One-Way ANOVA was used. This analysis showed that some bird species can be considered as indicators of urban areas, while others could be good indicators of wellpreserved large forests. Finally, it must be mentioned that the type and quality of the datasets are crucial to this type of study, because some species have a higher degree of sensitivity to certain types of vegetation or land cover. Therefore, the vegetation data must be produced as detailed as possible. At the same time, the species data needs to be collected based on the presence and absence (versus presence-only) of the birds.

Aim: The aim of this thesis is to describe the process by which the inherited disease, cystic fibrosis, (CF) was recognised as an important clinical entity in the United Arab Emirates (UAE) and the Sultanate of Oman (Oman). It examines the clinical presentation of the first patients and assesses their degree of severity. Further, it describes the first studies carried out to determine the underlying CF mutations associated with the disease in the UAE and Oman. An estimate is offered of the birth frequency of the condition. Overall, the cultural, geographical and historical aspect of the societies in which the disease occurs is stressed. Methods: An initial literature search was carried out using Medline of any literature pertaining to the Arab World and CF. this was read and classified into the relevance to Arabs in general, the Middle East and then specifically the Arab (Persian) Gulf societies. Thereafter, a clinic was established at Tawam Hospital, Al Ain, UAE, for children presenting With chronic respiratory disease that could serve as a national referral centre. It was run by the Author as a service of the Paediatric Department of the UAE University Medical School. I sent a letter to every Paediatrician working in the UAE informing them of our clinic and offering our services for the diagnosis and management of chronic respiratory disease in children. This was based on the author's experience as a respiratory paediatrician in Australia and New Zealand and as the Professor of Paediatrics in the UAE. No such service then existed in the UAE. Funding was sought to establish a research programme and develop a molecular genetics laboratory in the UAE Medical School. A series of successful research applications provided the grants to commence the investigations. Once a small number of children had been identified as having CF from those referred to the respiratory clinic, the initial project was to assess and report their clinical presentation. Following this an early start was made on the identification of the mutations responsible. Once these were established an attempt was made to estimate the frequency of the condition at birth. Additional clinical studies revolved around assessing the severity of the condition that was associated with the main mutations that were identified. A clinical comparison was made with those with the mutation AF508 and the other main mutation, despite the obvious limitation of small numbers then available. Radiological assessment was made to evaluate the progression of the disease. The final aspect of the study was to assess patients from Oman and compare their findings and mutations with the neighbouring UAE. Based on information gained hypotheses are proposed regarding the spread of the gene mutation by population drift. Thesis outline: A literature review is presented in the form of a critique on the disease and a resume of the relevant aspects of the genetics of CF. Additionally, facts about the two countries' geography and history are presented. Finally, knowledge about CF mutations and population origins from other areas is presented. The second main section deals with the clinical features of the disorder as it presents in the UAE. Molecular findings are then presented and details of the common mutation found in Bedouin Arabs. Hypotheses are then presented based on the information gathered. Results: CF is not a rare disease in the Arab children of the UAE and Oman. These findings refute previous reports of CF being a rare or non-existent disease in Arabs. The condition presents with a severe clinical picture, with early colonisation of the respiratory tract with staphylococcus, haemophilus and pseudomonas organisms, even with conventional CF management practices in place. The CF mutation S549R is prevalent in Arabs of Bedouin stock, while AF508 is found in those of Baluch origin. The former may be descendants of Arabs who left southern Arabia and travelled to the Trucial Coast at the time of the destruction of the great dam at Marib. The origins of this mutation may lie in the area that corresponds to the modern Republic of Yemen. The latter groups are descendants of those who came originally from Baluchistan. It is hypothesised also that the ancestral home of the AF508 mutation may be in the geographical area now known as Baluchistan, that spans three separate modern political territories. The evidence presented supports the concept that the S549R mutation may be associated with a severe, if not the severest, clinical pattern recognised. It equates with that seen with the homozygous AF508 genotype. The absence of an additional mutation in the promoter region accounts for the different clinical pattern seen in previously described patients. Conclusions: There needs to be a major awareness of the presence of CF as a severe clinical disease in the children of the Gulf States. The clinical presentation and findings support the concept of under recognition of the disease. Climatic conditions put the children at special risk of hyponatraemia and electrolyte imbalance. The absence of surviving adults with the disease suggests premature deaths have occurred, but the high fertility rates have maintained the gene pool for this recessive disorder.

Hector�s dolphin (Cephalorhynchus hectori) is an endangered coastal species endemic to New Zealand. Their distribution, like other marine organisms, is intertwined with the dynamics of their local habitats, and at a larger scale, the coastal waters around New Zealand. The main purpose of this thesis was to identify specific habitat requirements of this rare dolphin. Hector�s dolphin distribution around the South Island was quantified along several temporal and spatial scales. Large-scale density analyses of abundance surveys found over half of the South Island�s current population occurred within only three main regions. Two of these strongholds are along the west coast and the third is located around Banks Peninsula on the east coast. Smaller-scale analyses at Banks Peninsula found the majority of the dolphin community was preferentially using core regions within the marine mammal sanctuary. Monthly surveys showed that in summer and autumn statistically more dolphins occurred within inshore regions ([less than or equal to]one kilometre), spread throughout the surveyed coastline. From May through winter, dolphin densities rapidly declined. Remaining dolphins were significantly clumped in more offshore waters of eastern regions. The lowest encounter rates occurred between August and September. Certain 'hotspots' consistently had higher dolphin densities throughout the study period while others were preferred seasonally. To address habitat preferences, surveys simultaneously collected oceanographic samples using a CTD profiler. In general, physical variables of the Peninsula�s eastern and southeastern waters varied less, despite being regularly exposed to upwellings and the varied presence of sub-tropical waters. Semi-sheltered bays and shallow inshore waters were highly variable and more susceptible to spatially discrete influences, such as localised river outflows and exchange events. Several hydrographic features were seasonally predictable due to their dependence on climate. The stratification and location of the two dominant water masses (neritic and sub-tropical) accounted for over half of the temporal and spatial variability observed in oceanographic data. Possible relationships between oceanographic features and aggregations of dolphins within Banks Peninsula were examined using global regression and a spatial technique known as geographical weighted regression (GWR). GWR models out-performed corresponding global models, despite differences in degrees of freedom and increased model complexity. GWR results found relationships varied over localised scales that were concealed by global methods. Monthly GWR models suggested the seasonal presence and strength of local oceanographic fronts influenced dolphin distribution. Dolphin aggregations coincided with the steepest gradients between water masses along eastern regions of the Peninsula, and strong exchange events along the edges of the study area. The continued survival of this endangered species is contingent on its protection. Long-term monitoring programmes are needed for the three main strongholds identified in this study. The occurrence of Hector�s dolphin 'hotspots' along frontal zones within Banks Peninsula also suggests alternative and increased protection strategies are needed for this sanctuary to be effective. In light of this thesis� findings and based on marine protection research, future sanctuaries need to consider why Hector�s dolphins are preferentially using particular regions and how their association with certain oceanographic features can help make informed decisions on more appropriate protected areas.
