Freshwater Scottish loch settlements of the late medieval and early modern periods : with particular reference to northern Stirlingshire, central and northern Perthshire, northern Angus, Loch Awe and Loch LomondShelley, Matthew James Hamilton January 2009 (has links)
Freshwater loch settlements were a feature of society, indeed the societies, which inhabited what we now call Scotland during the prehistoric and historic periods. Considerable research has been carried out into the prehistoric and early historic origins and role of artificial islands, commonly known as crannogs. However archaeologists and historians have paid little attention to either artificial islands, or loch settlements more generally, in the Late Medieval or Early Modern periods. This thesis attempts to open up the field by examining some of the physical, chorographic and other textual evidence for the role of settled freshwater natural, artificial and modified islands during these periods. It principally concentrates on areas of central Scotland but also considers the rest of the mainland. It also places the evidence in a broader British, Irish and European context. The results indicate that islands fulfilled a wide range of functions as secular and religious settlements. They were adopted by groups from different cultural backgrounds and provided those exercising lordship with the opportunity to exercise a degree of social detachment while providing a highly visible means of declaring their authority. This thesis also argues that loch settlements were not a lingering hangover from the past, as some have suggested, but a vibrant part of contemporary culture which remained strong until the latter half of the seventeenth century before going into final decline and disappearing as a significant social phenomenon.

Previous issue date: 2018-02 / Capes / As águas urbanas passam por diversas intervenções no processo de desenvolvimento das cidades, sofrendo, muitas vezes, impactos negativos devido à ausência de planejamento e saneamento básico. A eutrofização, causada pelo enriquecimento dos corpos hídricos por nutrientes advindos de despejos de esgotos sem tratamento é um dos grandes problemas das águas superficiais urbanas. Tendo em vista a necessidade do desenvolvimento sustentável das cidades, continuamente procura-se por alternativas para o tratamento de águas poluídas que possam atuar de forma harmônica com a paisagem urbana. Este trabalho teve como objetivo a construção de um sistema de jardins flutuantes para a remediação das águas do pequeno açude localizado no campus sede da Universidade Federal de Campina Grande – PB. O experimento foi realizado numa área experimental de 400 m² de espelho d’água, a montagem do sistema se dividiu em três etapas, atingindo no final da terceira etapa uma cobertura superficial de 10%. As estruturas modulares foram construídas com bambu e paletes, sendo utilizadas diferentes espécies de plantas aquáticas e ornamentais e substrato de fibra de coco. O monitoramento foi feito por coletas semanais, em 13 pontos distribuídos na área experimental. Os parâmetros analisados foram: temperatura, pH, turbidez, condutividade elétrica, OD, DBO, DQO, clorofila-a, fósforo total, ortofosfato solúvel. Em relação às estruturas dos jardins, aquelas que não apresentaram problemas de estabilidade e flutuação, tiveram bons resultados e proporcionaram o bom desenvolvimento das plantas. As análises estatísticas dos dados mostraram que na área em estudo, houve variações significativas em todos os parâmetros estudados, apresentando resultados positivos de remoção de matéria orgânica e nutrientes em alguns dos dias monitorados. As interferências ambientais na área em estudo, como a precipitação e as cargas de efluentes, dificultaram a análise de eficiência dos jardins na qualidade da água, mas, apesar disso, foram encontrados resultados importantes. / Urban waters go trough many intervencions during the process of development of cities. Many times suffering negative impacts due to absence of planning and basic sanitation. Eutrophication caused by enrichment of water bodies by nutrientes from sewage dumping without treatment is one of the great problems of superficial urban waters. Because of the need for sustainable development in cities and the search for alternatives for the treament of polluted waters, this study has the objective of constructing a system of floating gardens to treat the waters of the pond located on the main campus of the Federal University of Campina Grande, Paraiba, Brazil. The experiment was performed on área, area of 400m2 of the superficial lawyer of the the pond. The building of the system was divided into three stages; at the end of the third stage, 10% of the superficial area was covered, modular structures were built with bamboo and pallets. Different species of ornamental aquatic plants and cocunut fiber substrate were used. Monitoring was performed weekly by collections from 14 points distributed throughout the experimental área. The parameters analyzed were; temperature, pH, turbidity, electric conductivity, DO, BOD, COD, clorophyl-a, total phophorus, soluble orthoposphate, TNK, amoniacal nitrogen, nitrite, nitrate, TDS, VDS, FDS. The structures of the gardeens that did not present problems with stability and flotation had good results and promoted good development. Statistical analysis of the data revealed in the study area, there were significant variations in all the studied parameters, presenting positive results of organic matter and nutrients removal in some of the monitored days. As environmental interferences in the study area, such as precipitation as effluent loads, made it difficult to analyze the efficiency of gardens in water quality, but despite this, important results were found.

Previous issue date: 2017-05-22 / CAPES / In 2014, satellites from the Philippines identified construction of large artificial structures by China on seven reefs on the disputed Spratly Islands, in the south China sea. It was the beginning of what would be called reef-islandization or construction of artificial islands. These structures are being designed to meet civil demands and for military purposes. As for this latter utility of artificial constructions, China has promoted a vague discourse, which in turn has contributed to escalating suspicions and tensions, which has drawn the attention of the world to Southeast Asia. Given this scenario, this paper aims to understand if the artificial islands are a risk response of China to the regional security dynamics of Southeast Asia. Through this, three specific objectives will be presented: to investigate which antecedent factors had the causal force to make China adopt the policy of construction of the artificial islands; Understand the prospect theory and its main definitions, and the functionality of the model of political legitimation; Describe what these artificial constructions are and what their role in China's territorial politics. The research is based on a qualitative methodology whose line of elaboration will be developed through two tools: descriptive and explanatory-exploratory. In addition to this, bibliographic tools will be used. In short, the dissertation will be worked over three chapters: in the first chapter a review of the literature on territorial disputes and prospect theory; the second chapter will address the context of artificial constructions and how China perceives itself within these territorial disputes.. Based on the analysis of the need to avoid future losses, the third chapter will address how China's dissatisfaction with the status quo of the dispute in the South China Sea led the country to accept risk policies in order to Change the dynamics of this territorial game. / Em 2014, satélites das Filipinas identificaram a construção de grandes estruturas artificiais pela China, em sete recifes, nas disputadas ilhas Spratly, no mar do sul da China. Era o começo do que se chamaria de reef-islandization ou construção de ilhas artificiais. Estas estruturas estão sendo projetadas a fim de atender, tanto demandas civis quanto militares. Para a esta última utilidade das construções artificiais, a China, tem promovido uma justificativa vaga, o que por sua vez tem contribuído para escalada de desconfianças e tensões, que tem atraído a atenção do mundo para o sudeste asiático. Diante deste cenário, o presente trabalho objetiva compreender se as ilhas artificiais são uma resposta de risco da China à dinâmica de segurança regional do sudeste asiático. Mediante a isto, três objetivos específicos serão apresentados: investigar quais fatores antecedentes tiveram força causal para fazer com que a China adotasse a política de construção das ilhas artificiais; entender a teoria do prospecto e suas principais definições, e a funcionalidade do modelo de legitimação política; descrever o que são essas construções artificiais e qual seu papel na política territorial da China. A pesquisa está pautada em uma metodologia qualitativa cuja linha de elaboração será desenvolvida através de duas ferramentas: descritiva e explicativo-exploratória. Somado a isto, serão utilizados instrumentos bibliográficos. Em suma, a dissertação será trabalhada ao longo de três capítulos: no primeiro capítulo será apresentadateoria do prospecto; o segundo capítulo abordará o contexto das construções artificiais e como a China se percebe no cenário de disputa atual. Partindo da analise de que se fazia necessário evitar futuras perdas à legitimidade do país, o terceiro capítulo abordará como a insatisfação da China frente ao status quo da disputa no sul do mar da China, conduziu o país a aceitar políticas de risco a fim de mudar a dinâmica deste jogo territorial.

La clé des champs : enclavement et immunité territoriale de l'exploitation pétrolière en Afrique centrale (Tchad, Guinée Équatoriale, São Tomé et Príncipe) / Enclosing and territorial immunity of oil production areas in central Africa (Chad, Equatorial Guinea, São Tomé and Príncipe)Donner, Nicolas 01 December 2014 (has links)
La présente thèse propose de réfléchir au « statut territorial » des espaces de la production pétrolière en Afrique centrale. Et ce en explorant d’abord – derrière les évidences d’un « enclavement » ordinairement admis de ces espaces (mais sans que celui-ci soit véritablement réfléchi) – leurs modes de production architecturaux : à la fois ceux des « enclaves pétrolières » en tant que telles, que l’on proposera de théoriser en tant qu’« îles artificielles » en les réfléchissant au vaste miroir des constructions techniques humaines, et ceux des systèmes spatiaux qui les portent : architectures internationales dont les « enclaves » apparaissent comme autant de clés de voûte – signalant alors cette croissante tension qu’aiguise le monde contemporain entre le développement d’interdépendances et de compénétrations territoriales de plus en plus vitales, et la persistance et la continuation – également fondamentale – du découpage de la scène internationale en unités territoriales souveraines. L’exploitation pétrolière – paradoxe dont on traquera la vérité – apparaissant autant comme un puissant facteur de construction de frontières internationales (dont on exposera quelques dynamiques en cours dans le golfe de Guinée) et comme une activité induisant et produisant différentes formes de découplages entre territoires étatiques et souverainetés, auxquelles l’exploitation et les investissements qui la sous-tendent supportent mal d’être assujettis. Ainsi explorerons-nous, au travers de l’étude des relations contractuelles nouées entre industriels et souverains, ainsi qu’au travers des techniques de financement telles que mobilisées dans le projet Tchad-Cameroun, comment l’exploitation pétrolière, parce qu’elle réclame une conséquente immunité à l’égard des risques qui pèsent sur elle (et au premier rang desquels figure le risque souverain), tend à produire des modes d’enclavement des territoires de l’exploitation. Car c’est ce que tend à démontrer cette thèse : que ces enclaves sont bel et bien des territoires, lesquels réclament toutefois d’être conceptualisés de façon à pouvoir concilier leurs dimensions « extraterritoriales » et leur toujours nécessaire ancrage dans la souveraineté territoriale étatique. / This thesis aims to conceptualize the oil production areas’ territorial status in central Africa. It first proposes to explore – behind the false evidence of an “enclave status” which is commonly accepted without being theorized – their architectural patterns: both those of the “oil enclaves” as such – which will be conceptualized as “artificial islands” by mirroring them with the vast domain of human technical constructions –, and those of the international spatial systems without which they could not exist – oil production spaces appearing as keystones of such systems. They thus highlight one of the contemporary world’s greatest tensions, which stand between the increasingly vital nature of international interdependences and territorial permeations, and the persistence and continuation – as well fundamental – of the territorial and sovereign partition of our world. Oil production – and we will inquire about the truth that hides such a paradox – concurrently appearing as a powerful factor in building international borders (which we will be discuss some current dynamics in the gulf of Guinea) and as creating various ways of unbundling territories and sovereignties, given that nor the activity nor its financial investors easily bear being at sovereign powers’ mercy. We will thus explore – through the contractual relations that intimately tie oil companies and sovereign powers, and through financing techniques such as those Exxon called up in the Chad-Cameroon project – how oil production – because it requires being consequently immunized against political and sovereigns' risks – tends to create various ways of territorial enclaving. And here is what this thesis seeks to demonstrate: that oil enclaves are territories – territories which claim to be conceptualized so as to reconcile their “extraterritorial” extent and their still crucial implant in the sovereign territory.
