Abstract:

In the present dissertation I present a broad instrumental account of the legitimacy of independent central banks. I claim that if the right institutional design is chosen, and it protects democratic participation in several ways and promotes sorne basic distributional goals of the government, the institution of central bank independence might be legitimate, and thus the government might not weaken its own right to rule, or moral authority to crea te enforceable political obligations, when it delegates control over monetary policy to an independent agency. I also offer a sufficientarian account of the central bank's duties of distributive justice, which claims that the concern to insulate monetary policy from electoral manipulation does not require pursuing only the goal of eliminating inefficiency. The bank should, in addition, protect and promote the basic distributional values of the government. I argue that independent central banks should also protect individuals from unemployment, since monetary policy has such deep effects on employment, and they should to manage the risks generated by financia} regulations in ways that avoid jeopardizing the provision of a social mínimum, a precondition for any legitimate set of basic structural institutions. Finally, the international aspect of my dissertation explores four arguments to claim that the asymmetries between the least competitive countries and their competitors have been exacerbated by the Eurozone and cannot adequately be dealt with by relying only in intra-state solidarity.
En aquesta tesi defensa que la legitimitat de la independencia dels bancs centrals independents pot ser reconeguda per una concepció amplia de l'instrumentalisme. Si el disseny institucional és l'adequat, i protegiex la participació democriitica de diverses formes i promou els valors distributius basics del govern, la institució dels bancs centrals independents pot ser legítima, i per tant el govern no debilita el seu dret a governar, ni la seva autoritat moral per crear obligacions polítiques subjectes de ser executables, quan delega les seves funcions en una agent independent. Així mateU: presento una visió suficientarista dels deures de justicia distributiva del banc central, que sosté que la preocupació per ai"llar la política monetaria de la manipulació electoralista no requereU: perseguir com a únic objectiu la eliminació de la ineficiencia. Els bancs centrals independents han de protegir els individus de l'atur, atesa la influencia de la política monetaria en les polítiques d'ocupació, i han de gestionar els riscos generats per la regulació financera de manera que no impedeixin la provisió d'un mínim social, que és una pre-condició per a la legitimitat de qualsevol conjunt d'institucions basiques estructurals. Finalment, l'aspecte internacional de la tesi explora quatre arguments per justificar que les assimetries entre els pai"sos menys competitius i els seus competidors s'han exacerbat per la creació de l'Eurozona i no poden ser gestionades adequadament si es confia solament amb la solidaritat intra-estatal.

Abstract:

This thesis consists of three empirical papers on central bank institutional design.Chapter 1 contributes to the debate on the importance of central bank independence (CBI) in lowering inflation rates. It stresses the relevance of employing indices of central bank independence computed dynamically in two ways. First, it recomputes the evolution of the Grilli et al. (1991) index of CBI and shows that the timing of large legislative reforms is closely related to inflation rate dynamics. Using unit root tests with endogenous structural breaks, I find that reforms that modify the degree of CBI represent structural breaks in the inflation rate dynamics. Second, employing the dynamic Grilli et al. (1991) index of independence confirms the negative relationship between CBI and inflation in a sample of 10 advanced economies.Chapter 2 presents a new and comprehensive database of central bank institutional design for 65 countries over the period 1972--2014. This chapter describes in detail the sources of information and the coding rules used to create a new index of central bank independence. It also compares this new index with the classical measures of CBI and highlights the new aspects of central bank institutional design included in this database such as financial independence and accountability. An important innovation of this new index is its dynamic nature. This enables an investigation of the endogenous determination of the level of independence of central banks and suggests several instruments for the CBI index. Using an instrumental variable approach, this chapter provides strong support for a causal, negative CBI-inflation nexus.Chapter 3 uses a political economy framework to investigate the drivers of reforms in central bank institutional design. Using the new CBI index developed in Chapter 2, this Chapter investigates the determinants of central bank reforms in a sample of 65 countries over the period 1972--2014. The results obtained suggest that the incentives generated by initial reforms which increased the level of independence, as well as a regional convergence, represent important drivers of reforms in central bank design. At the same time, an external pressure to reform, such as obtaining an IMF loan or joining a monetary union, also increases the likelihood of reforms, while government changes or crises episodes have little impact

Abstract:

Dissertação de Mestrado Integrado em Arquitetura, com a especialização em Urbanismo apresentada na Faculdade de Arquitetura da Universidade de Lisboa para obtenção do grau de Mestre.
O tema deste Trabalho Final de Mestrado intitula-se Periferia Central – Revitalização e Reabilitação do Parque Industrial da Venda Nova. Desconetado e descaracterizado são palavras que descrevem o antigo centro dinamizador da Amadora. A Era industrial deixou fortes marcas no desenvolvimento da cidade produzindo novas dialéticas no antigo tecido rural, no entanto estas marcas com o processo de desindustrialização são edifícios abandonados e em ruína e um espaço público desprezado. A expansão da linha metropolitana e a criação da estação de metro da Reboleira valorizaram o local, no entanto a falta de qualquer elemento atractor tornam-na numa qualidade desperdiçada. Deste modo, o presente trabalho pretende a revitalização do Parque Industrial da Venda Nova através de uma estratégia de projeto que forneça uma nova identidade ao local, criando uma nova centralidade na cidade da Amadora, apoiada numa imagem arquitetónica e numa rede de espaço público de referência. Dado o tema e a área selecionado para o desenvolvimento da proposta, tornou-se necessária a compreensão de temáticas relativas às periferias urbanas e questão da sua centralidade; o impacto da obsolescência industrial, o valor do património industrial e a influência que os polos de inovação podem produzir para a mitigação da fragmentação dos territórios que sofreram com este fenómeno; e por fim a relação do espaço público como elemento fundamental da cidade para a revitalização de tecidos urbanos.
ABSTRACT: The theme of this Master’s Final Project is entitled: Central Periphery – Revitalization and Rehabilitation of the Venda Nova Industrial Park. Disconnected and featureless are some of the words used to describe the old center of Amadora. The Industrial Era left marks in the city development, producing new dialects on the old rural tissues, however these marks with the deindustrialization process are abandoned and decaying buildings and a disregarded for public space. The expansion of the metropolitan line and the Reboleira Station value the area, but the lack of any attractive element turns it in a wasted quality. Thus, the present project proposes the revitalization of the Venda Nova Industrial Park by creating a project strategy that can provide a new identity to the area, raising a new centrality in the city of Amadora supported by a new architectural image and a public space system. According to the theme and the selected area for the development of the proposal, it became necessary understanding subjects related to the urban peripheries and their centrality factor; the impact of industrial obsolescence, the value of industrial patrimony and the influence that innovation clusters can produce on quenching fragmented territories; and finally the public space as a fundamental element on the revitalization of old urban tissues.

Abstract:

Climate change is today one of our highest priority challenges. But to understand the change in climate and to be able to make predictions about the future, knowledge about past climate is of substantial importance. The key archive of past climate change can be studied through loess deposits. This paper examines loess sources in Europe and how deposits can tell us about different origins through different geochemical techniques and methods. Secondary data of loess deposits and sources over Central-Eastern Europe have been collected and examined in order to test some of the possible major dust source areas for European loess deposits that have been suggested by other scientists. Different techniques and methods are used to examine loess sediments when trying to identify their origin. Generally, techniques and methods can be divided into geochemical and analytical parameters, which are XRD (X-ray diffraction) and XRF (X-ray fluorescence spectrometry), elemental ratios, SrNd isotopic analyses, zircon U-Pb geochronology, combined bulk and single grain analyses, as well as more statistical approaches. The results are based on the three mainly studied articles show that it is more likely that loess sources are coming from High Alps and mountain areas, such as the Carpathians, rather than from glaciers, as was previously the main idea. This paper therefore draws the conclusion that loess material, in most cases, seems to be originating from relatively nearby and local mountain areas and only a small portion appear to have been transported longer distances.

Abstract:

Having worked on my master thesis on the macro-lithic tools from the Neolithic sites of the central part of Serbia or so-called Middle Morava valley, we noticed that there is not enough interest in this archaeological category in the central Balkans. The short research tradition and the small number of researchers have resulted in an insufficient number of published research results. This situation limits the implementation of new methodological approaches, such as those developed in the other parts of southern and central Europe, and weakens the advance in the archaeological knowledge on prehistoric economies. In order to overcome these problems, we have examined 2174 macro-lithic tools from the 12 Neolithic settlements (~ 5900 - 4650/4600 BC cal) from the Central Balkans. Thus, we have applied economic theory as the theoretical background of the geological, morpho-technical and functional analysis of macro-lithic artefacts (chapter 2). The study presents settlements, the archaeological context in which the analysed artefacts were found, paleo-environmental and geomorphological settings of the Central Balkans. One part of the thesis displays the results of the petrographic analysis of raw material from other Neolithic archaeological sites from previous studies, and samples from geology outcrops from the Central Balkans. The same part presents the results of our geoarchaeological survey related to macro-lithic artefacts from Motel Slatina and Turska česma, Slatina. The petrographic analysis of the studied artefacts also allows us to identify the location and the distance from which raw materials derived, the exploitation method and the existence of territorial borders between supply areas. Functional analysis has revealed for the first time, an appearance of standardized macro-lithic tools. This result has defined high volume production and characterized economy of the Late Neolithic. These results allow us to observe technological changes among the Early and Late Neolithic macro-lithic societies and economic differences between settlements and regions during the Late Neolithic.

In this work, we studied the literature of the interbank market and how a central bank can improve its functioning. We developed a framework that could accommodate the different models of the interbank market and central bank intervention created from Bryant (1980) and Diamond and Dybvig (1983). With this we show that, in most cases, banks with access to the interbank market are unable to provide the efficient allocation for its consumers. In this environment we find a role for a central bank that, by intervening in the interbank market, is able to induce banks to offer the same allocations that would be provided by a social planner, that is, efficient allocations.

Criamos um framework que pudesse acomodar os diferentes modelos de mercado interbancário e intervenção do banco central criados a partir de Bryant (1980) e Diamond and Dybvig (1983). Com isso mostramos que, em grande parte dos casos, os bancos com acesso ao mercado interbancário são incapazes de prover a alocação eficiente para os seus consumidores. Nesse ambiente, encontramos uma função para um banco central que, ao intervir no mercado interbancário, é capaz de induzir os bancos a oferecerem as mesmas alocações que seriam providas por um planejador central, ou seja, alocações eficientes.

Abstract:

Following the opening chapter, which surveys existing literature on the transparency of central bank communication, the remaining chapters each address a simple question to better understand central bank communication, and its effects on financial markets using the European Central Bank (ECB) as a case study. Specifically: o How informative is ECB communication. Chapter 2 provides a glossary that translates explicitly the qualitative information of ECB President monthly press conferences into an ordered scale. We show that the predictive ability of these statements is similar to market-based measures of monetary policy expectations. Moreover, we find that ECB words provide complementary information to macroeconomic variables. o Is it possible to measure objectively qualitative statements. Chapter 3 uses Alceste, textual-content analysis software, to categorize each ECB announcement. We find that these categories explain the volatility of financial market expectations of future monetary policy, but are not statistically helpful in predicting future policy actions. o Is the ECB transparent about its monetary policy framework. Chapter 4 proposes an indirect test of transparency. By looking at ECB explanations of its monetary policy decisions we identify new measures of euro area economic activity and price stability. Then, we use these macroeconomic variables to estimate an ECB-specific empirical reaction function, which better forecasts its future actions compared to standard Taylor-type rules. o Do financial intermediaries understand and believe ECB statements. The final chapter shows that innovations in market expectations about future monetary policy can be explained by unexpected ECB announcements. Hence, we conclude that even if the ECB is a relatively young multinational financial institution, it has already acquired a reputation for telling the truth. Moreover, in order to describe properly its monetary policy we need two dimensions: both the current policy rate and its planned future path.

Abstract:

El hombre en su quehacer cotidiano, se desenvuelve constantemente en un espacio físico definido, con el que se identifica a través de distintas actitudes. Es así que es preocupante abordar el complejo vivencial del espacio, solamente como objeto perceptual, sin mayor preocupación por el usuario que es que lo ocupa, se desarrolla y nutre de constantes experiencias. Experiencias que enriquecen el espacio en todo momento, dándole cualidades que a lo largo de la historia de la humanidad se han ido expresando con sus culturas, testigo de estos hechos, los cuales trataremos en lo que concierne al espacio que aquí designaremos central y que será nuestro tema de estudio. De esta manera el presente trabajo tiene como finalidad el poder reflexionar sobre una de las cualidades del espacio arquitectónico y urbano como gestor de contenidos sociales. Entendido así no nos introduciremos a problemas del espacio, propios del campo de la proporción o de la idealización de las formas. Llevaremos el presente estudio recurriendo mochas veces a expe¬riencias extra-disciplinarias, desde la psicología de la percepción (gestalt) hasta la antropología o desde la teoría de la información, hasta la semiológica para así poder ser capaces de comprender el "espacio central", categoría que luego definiremos como un gestor de conte¬nidos. Hemos observado que indistintamente a épocas y estilos ciertos hechos se repiten, más éstos no serán tratados como una simple narración e ilustración, sino intentando poder encontrar ciertos valores capaces de hacernos comprender los acontecimientos según constantes que se advierten tanto en el pasado como en el presente a modo de un recolector de experiencias. De igual, manera creemos que algunos casos, por sus características particulares, merecen ser tratados aparte y que otros pueden estudiarse dentro de la generalidad. Por otro lado no hemos creído conveniente estudiar el "espacio central" mediante abstracciones, sino recurriendo a las obras arquitectónicas y urbanas. Entendamos estas como obras que filológicamente nos pueden llevar a comprender una serie de tipologías, las cuales estudiaremos y valoraremos.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
Este artigo considera o papel da comunicação como um instrumento de política usado pelo Banco Central. No modelo, um Banco Central que possui mais informação que os formadores de preço sobre o estado da economia pode, através de uma comunicação sem custos (cheap talk ), influenciar suas decisões de precificação. Nós relacionamos o grau de comunicação a fundamentos da economia, como as preferências do Banco Central, a quantidade de informação que os agentes possuem e o grau de complementariedade de suas decisões de precificação.
This paper considers the role played by communication as a policy instrument by the Central Bank. In the model, a Central Banker who is better informed than the price setters about the state of the Economy can, through (cheap talk) communication, influence their pricing behavior. We relate the degree of communication to fundamentals of the economy such as the Central Banker`s preferences, the amount of information possessed by market agents and the degree of complementarity in their price- setting decisions.

Abstract:

Central aortic systolic blood pressure (cSBP) differs from peripheral systolic blood pressure (pSBP) measured in the arm. cSBP may be estimated non-invasively by application of a generalised transfer function (GIF) to a high fidelity peripheral arterial waveform or from the late systolic shoulder (SBP2) of such a waveform. The relative accuracy of these estimates and the degree to which they depend on the accuracy of peripheral blood pressure is unknown. The interest in estimates of central blood pressure is driven in large part by the fact that aortic pulse pressure (cPP) is thought to be a better predictor of cardiovascular risk and response to antihypertensive treatment than peripheral BP. However, little is known concerning the mechanism by which drugs may reduce cPP independently of effects on peripheral BP. Objectives of this thesis were to: 1. Examine the relative accuracy of different methods (GTF and SBP2) for estimating cSBP and cPP from a high fidelity peripheral arterial waveform. 2. Determine errors introduced by non-invasive calibration of this waveform (as would be the case when such methods are used in practice), 3. Explore the use of a simplified method for estimating cSBP based upon pressure oscillations within an arm cuff. 4. Determine the mechanism by which nitroglycerin (NTG, a drug that has relatively selective actions to lower cSBP) lowers cPP. Pressure and in some cases combined pressure and flow velocity were acquired at the aortic root during cardiac catheterisation. Peripheral blood pressure was measured by oscillometry and peripheral blood pressure waveforms were obtained from blood pressure cuffs, radial tonometry and a servo-controlled finger cuff. To address objective 4 additional measurements of ventricular and arterial mechanics where made using ultrasound and magnetic resonance imaging.

Abstract:

La valorizzazione dello scalo ferroviario di Verona Porta Nuova è stata avviata nel gennaio 2020 con il bando di gara pubblicato da FS Sistemi Urbani, che prevede la riconversione dell'area in un parco urbano, connotato dall’insediamento di un mix di funzioni pubbliche e private. Il bando ha rappresentato il punto di partenza per condurre un’analisi sulla complessa realtà del territorio veronese: in particolare, è stata articolata un’indagine sulle relazioni e sulle connessioni esistenti tra i mutevoli volti della città. Nel primo capitolo si delinea la storia urbana della città, procedendo dalla scala generale per poi progressivamente osservare più in dettaglio l’evoluzione del quadrante sud, quindi dell’area ferroviaria collocata al suo interno. Ciò fa emergere le interazioni esistenti nel tessuto frammentario della città e suggerisce alcune chiavi per una lettura d’insieme del contesto di riferimento. Viene parallelamente esplorata fascia perimetrale dell’ex scalo merci, di cui sono discusse le criticità che la definiscono come barriera e cesura del tessuto urbano. Per immaginare la sua possibile trasformazione, tale scenario viene in ultimo considerato adottando una prospettiva più ampia, mediante il confronto alcune esperienze di rigenerazione attuate in spazi complessi in diversi contesti europei. Nel terzo capitolo, come sintesi ed esito delle indagini svolte, viene presentata l’ipotesi progettuale “Verona Central Park”, in cui l’infrastruttura verde costituita dal grande parco urbano, pur mantenendo viva la memoria ferroviaria del luogo, si inserisce nel tessuto urbano come nuovo dispositivo di connessione: occasione di scambio e interazione e punto di innesco di nuove dinamiche di sviluppo che coinvolgano le zone contigue, oggi separate.

Memoria para optar al título de Arquitecto
El proyecto es un edificio de viviendas de interés social, sumado a estacionamientos en subsuelo, comercio en el nivel de suelo y oficinas en nivel dos, tres y cuatro. Está ubicado en el triángulo fundacional de la comuna de Santiago, en la esquina de Calle Monjitas con Calle Mac Iver. El objetivo del proyecto es proponer nuevos mecanismos de distribución de suelo en la ciudad y de gestión de éste y a la vez mejorar la calidad y ubicación de las viviendas sociales, proponiendo un nuevo modelo que, pretende garantizar el acceso al suelo en la ciudad, con la finalidad de construir así una ciudad más equitativa. Estará ubicado un sitio eriazo en el triangulo fundacional de Santiago, siguiendo la tendencia de la vuelta a la ciudad construida, la cual se ha venido manifestando en estos últimos años. Una de las maneras que se utilizará como método de financiamiento es la recuperación de plusvalías por parte del sector público, tema que será desarrollado mas adelante. Se sugerirán acciones que permitan concretar las ideas y lineamientos de la Política Nacional de Desarrollo Urbano, la cual fue publicada este mismo año.

Abstract:

This thesis examines the rise and fall of a coconut-based enclave economy in the administrative post of Micaúne in the district of Chinde, Zambézia Province. Residents of Micaúne derived their livelihoods from the coconut economy for over a century. My research is based on ethnographic fieldwork undertaken between 2010 and 2014 over a period of eight months in this administrative post. Although coconut had been a familiar crop to people in the Micaúne area for centuries, it became central to the local economy only after the advent of colonial settler capitalism in the 1880s. I argue that the longevity of the coconut economy, and the stability and predictability that it brought to Micaúne residents, were the outcome of its embeddedness in the local social organisation and mode of production. From the last decades of the 19th century, Micaúne's economy was dominated by Société du Madal, initially a French-owned company that established coconut plantations in the area and produced commodities derived from the coconut palm for sale on international markets. Madal became a 'total institution' in Micaúne because it was the major landholder, employer of local labour, supplier of goods through its shops and the main purchaser of coconut from growers in the area. This study suggests that a 'customary' law relating to inheritance in Micaúne reinforced the centrality of the coconut economy in local society for much of the 20th century by making specific reference to the inheritance of trees. The implication of this law was that control and ownership of trees rather than land was the major determinant of local livelihoods. But as in any enclave economy, when the resource on which it is based is depleted, the collapse of the whole system is inevitable. In the case of Micaúne, an ecological crisis in the 1990s, in the form of a plant disease known as Coconut Lethal Yellowing Disease (CLYD, infected and killed most of the palm trees, both on Madal's and local families' land, which were the backbone of the local economy. As a result, the company-based welfare system that Micaúne residents enjoyed for more than a hundred years disappeared overnight, a catastrophe that caused unprecedented uncertainty and despair in the area. The local people's main sources of income and employment shrank and there have been many confirmed reports of hunger and starvation amongst the Micaúne population in the 2000s and after. In sum, the majority of Micaúne residents are now 'food insecure', except for a few who are local businessmen and people employed by or getting stipends from the state. It is evident from my research that attempts by the government and NGOs to promote food security initiatives failed to solve the problem. On the contrary, these initiatives have fuelled a growing demand for land, which has led to its increasing commodification (including the emergence of an illegal land market). This development has also triggered emergent claims of land ownership based on a new notion of autochthony. A clear distinction between 'natives' and non-'natives' (newcomers) is now being drawn in Micaúne. Claiming to belong to the category of autochthons is seen as a basis for entitlement to prior rights over resources such as minerals recently discovered in the district. I argue that the promise of minerals resources might explain why, despite the extremely harsh living conditions that local residents have faced since the demise of the coconut economy, they have decided to remain in this area while scouting in the interim for alternative livelihoods options, which are limited to subsistence farming and fishing, and petty trade. They seem to be waiting for the materialisation of big investments in mineral resources or in other development initiatives often touted by the central government in Mozambique.

Abstract:

Cette thèse est une tentative de mieux comprendre l’impact des différentes mesures prises par les banques centrales depuis 2008, et en particulier en zone Euro. Elle se concentre sur les effets des différents politiques non-conventionnelles sur le marché monétaire. Le chapitre 1 montre comment la fragmentation du marché interbancaire perturbe la transmission de la politique monétaire. Le phénomène de fragmentation est introduit dans un modèle standard de marché interbancaire. On voit alors que de la liquidité excédentaire apparaît de façon endogène dans le modèle. Cela conduit les taux d’intérêt à court terme à s’éloigner du taux de la banque centrale. Le modèle est utilisé pour analyser les politiques conventionnelles et non conventionnelles de l’Eurosystème. Le chapitre 2 explique comment le programme d’achat de titres souverains de l’Eurosystème (le PSPP) a poussé certains taux du marché monétaire en dessous du taux de la facilité de dépôt de l’Eurosystème, qui est pourtant sensé être un plancher. Le chapitre explore empiriquement les interactions entre le PSPP et les taux d’intérêts collatéralisés. Le chapitre 3 montre comment des régulations très proches de celles de Bâle III étaient utilisées par les banques centrales dans les trois décennies qui ont suivi la Seconde Guerre mondiale. A l’époque ces régulations étaient utilisées pour stabiliser l’inflation et la production, un rôle qui serait aujourd’hui typiquement attribué à la politique monétaire (et non à la régulation bancaire). Les expériences historiques que nous décrivons montrent clairement que la régulation de la liquidité a des effets restrictifs sur l’activité
The first chapter shows how interbank market fragmentation disrupts the transmission of monetary policy. Fragmentation is the fact that banks, depending on their country of location,have different probabilities of default on their interbank borrowings. Once fragmentation is introduced into standard theoretical models of monetary policy implementation, excess liquidity arises endogenously. This leads short-term interest rates to depart from the central bank policy rates. Using data on cross-border financial flows and monetary policy operations,it is shown that this mechanism has been at work in the Euro-Area since 2008. The model is used to analyze conventional and unconventional monetary policy measures. The second chapter shows how the Euro area money market rates have been standing below the deposit facility rate since 2015, which financial markets perceive as a byproduct of Eurosystem's public sector purchase program (PSPP). This paper explores empirically the interactions between the PSPP and short term secured money market rates (repo rates). We document different channels through which asset purchases may affect the various segments of the Euro area repo market. Using proprietary data from the PSPP and individual repo transactions made on the repo market for specific securities, our results show that the PSPP has contributed to push down repo rates. Purchasing 1% of a bond outstanding is associated with a decline in its repo rate of -0.75 bps

Abstract:

Cette étude est une contribution à la connaissance de la biodiversité, la distribution géographique et la conservation des Rubioideae (Rubiaceae) d’Afrique centrale (Burundi,R.D.Congo et Rwanda). Le travail est basé sur l’analyse critique des riches collections conservées dans les grands herbaria de Belgique et du Burundi (plus de 10.000 échantillons). Une check-list critique des Rubioideae d’Afrique centrale a été établie; 291 taxons ont été inventoriés et une carte de distribution géographique a été tracée pour chacun, après géoréférencement de toutes

les récoltes. Des taxons nouveaux pour le territoire étudié ont été découverts, révélant le caractère incomplet de la ‘World check-list of Rubiaceae’. Des taxons nouveaux pour la science ont été mis en évidence. Une espèce nouvelle (avec deux variétés) a été décrite. Les analyses de distribution ont utilisé deux niveaux de résolution: le système d’information géographique (SIG) pour la production des cartes de la distribution des espèces et le système de maillage pour calculer la densité et l’effort d’échantillonnage. La richesse floristique apparente est fortement biaisée par l’intensité d’échantillonnage. Après correction de ces biais, la diversité reste inégalement répartie.

Des régions de plus haute diversité peuvent être expliquées à la fois par des processus déterministes (régions à haute diversité ’habitats), et, probablement aussi par des contingences historiques (refuges). Elles correspondent à des zones de spéciation active ou de moindre extinction. De plus, cette diversité varie selon les phytochories considérées.

La distribution des taxons a été utilisée pour tenter de redéfinir sur une base objective des subdivisions phytogéographiques du territoire étudié. L’approche basée sur la similarité floristique et la distribution potentielle a démontré le rôle déterminant des taxons indicateurs et des variables environnementales

dans l’établissement d’un système cohérent de phytochories pour l’Afrique centrale. Un nouveau

système de trois territoires floristiques défini sur base des Rubioideae est comparativement proche de celui de White (1979, 1983) mais ne comprend pas des zones de transition.

Enfin, la caractérisation de l’état de conservation des Rubioideae de la zone d’étude, sur base de la méthodologie de l’UICN, a porté sur cinquante-six taxons (sub-)endémiques d’Afrique centrale. L’évaluation paramétrique a été largement utilisée. Elle est basée sur la détermination de la zone d’occupation (AOO) et de la zone d’occurrence (EOO). La proportion des Rubioideae menacés et coïncide avec celles des autres groupes déjà évalués. Cette analyse a démontré qu’il existe une corrélation entre les taxons menacés et les zones de forte concentration humaine.

This study is a contribution to the knowledge of biodiversity, geographic distribution and conservation of Rubioideae (Rubiaceae), a group of flowering plants in Central Africa (D.R.Congo, Rwanda, Burundi). The work is based on the critical evaluation of the rich herbarium collections conserved in Belgium and Burundi (> 10,000 specimens). A critical check-list of Rubioideae in Central Africa has been produced, comprising 291 taxa. A distribution map has been obtained for each of them. A number of taxa are new to the area, highlighting the gaps of knowledge in the ‘World check-list of Rubiaceae’. Species new to science have been detected, one of which has been formally described (with two varieties) in this study. The analysis of distribution patterns has been performed at two levels of resolution. Grid-maps have been used to analyse patterns of species diversity. Floristic richness appears strongly correlated with

sampling effort. After correction for sampling effort, species diversity remains heterogeneous.

Regions of higher diversity correspond either to areas of more active speciation, in relation to a high diversity of habitats, or to forest refuges where extinction rates have been lower. Additionally, this diversity varies between the different phytochoria recognized. The distribution of species has been used in an attempt to redefine phytochoria based only on floristic criteria. Floristic similarity, and potential distribution (based on climatic parameters), has shown that phytochoria can be effectively defined and characterized by the method of indicator taxa. Three major

phytochoria show a reasonably match with phytochoria previously proposed by White (1979, 1983), but White’s transition zones are not highlighted. Finally, distribution data have been used to critically evaluate the conservation status of 56 taxa, using the methodology and criteria of IUCN. The area of occupancy (AOO) and extent of occurrence (EOO) were calculated and used as main criteria to evaluate the species. A relatively high proportion of taxa appear to be threatened, especially in relation to urbanization and deforestation in the most

highly populated parts of the study area.

Abstract:

Human pressure on forest resources increased significantly during the past decades through land use and land use change, especially in the tropics where forest clearing is a major source of CO2 release in the atmosphere. Consequently, forests are the focus of international environmental policies and discussions aiming to reduce emissions from deforestation and forest degradation (i.e. REDD+). The capacity of participating countries to regularly provide accurate forests C stocks measurements at a national scale thus represents an important challenge to address. In dense forests, generally only the above ground biomass (AGB) is measured as it accounts for more than 50% of total C stocks. However, important gaps remain at each scale of measurement, i.e. from felled tree to regional mapping, with the resulting errors propagation through these different scales being probably the most concerning issue.

In the present work, we propose to address these issues by using a multi-scale approach in order to improve our global understanding of AGB variations in dense tropical forests of Central Africa. In particular, we studied (i) forest AGB prediction from remote-sensing textural analysis, (ii) the potential role of largest trees as predictor of the entire forest-stand AGB and (iii) intra- and inter-individual radial variation of wood specific gravity (WSG, i.e. oven-dry mass divided by its green volume) and its potential consequences on the estimation of the AGB of the tree.

First, we analyzed the potential use of textural analysis to predict AGB distribution based on very high spatial resolution satellite scenes. In particular, we used the Fast Fourier Transform Ordination (FOTO) method to predict AGB from heterogeneous forest stands of the Democratic Republic of the Congo (DRC). Here, based on 26 ground plots of 1-ha gathered from the field, plus a successful combination of Geoeye and Quickbird contrasted scenes, we were able to predict and to map AGB with a robust model (R² = 0.85; RMSE = 15%) based on textural gradients.

Secondly, the research of AGB indicators was focused on the dissection of the role played by largest trees. Here we found largest trees not only hold large share of forest carbon stock but they contain the print of most of forest-stand structure and diversity. Using a large dataset from western Cameroon to eastern DRC, we developed a non-linear model to predict forest carbon stock from the measurement of only a few large trees. We found the AGB of the 5 % largest stems allow to predict the AGB of the entire forest-stand yielding an R² of 0.87 at a regional scale. Focusing on largest trees species composition, we also showed only 5 % of species account for 50 % of total AGB.

In the end, we investigated inter- and intra-individual WSG variations. Despite recognized inter- and intra-specific variations along the radial axis, their ecological determinants and their consequences on trees aboveground biomass assessments remain understudied in tropical regions. To our knowledge, it has never been investigated in Africa. Using a 3-D X-Ray scanner, we studied the radial WSG variation of 14 canopy species of DRC tropical forests. Wood specific gravity variance along the radial profile was dominated by differences between species intercepts (~76%), followed by the differences between their slope (~11%) and between individual cores intercept (~10%). Residual variance was minimal (~3%). Interestingly, no differences were found in the comparison of mean WSG observed on the entire core and the mean WSG at 1-cm under the bark (intercept ~0; coefficient = 1.03). In addition, local values of WSG are strongly correlated with mean value in the global data base at species level.

I deeply believe these results favor the development of promising tools to map and to estimate accurately the AGB of tropical forest-stands. The information provided by largest trees on the entire forest-stand is particularly interesting both for developing new sampling strategies for carbon stocks monitoring and to characterize tropical forest-stand structure. In particular, our results should provide the opportunity to decrease current sampling cost while decreasing its main related uncertainties, and might also favor an increase of the current sampling coverage.

Abstract:

How to display objects which were detected from different devices in one coordinate system? Nowadays most vehicles are equipped with front and back sensors to help the driver in driving process. Companies who provide this technology need to have an application which enables them for easy data fusion from these sensors and recording the process. Besides sensor’s design, programming of them is an important aspect. BASELABS Connect has the solution in a user friendly way. Creating Sensor Central component for BASELABS Connect is the main goal of this thesis. Sensor Central from BASELABS Connect requires six variables of sensor’s position for each sensor to demonstrate the objects from all sensors to one unique coordinate system. In this thesis, it was intended to create such a component which was mounted between all the sensors and the charting component to convert the objects location from different sensor’s position to one coordinate system and to be usable from other vehicles too.

Esta dissertação é dedicada ao estudo das taxas de convergência no Teorema Central do Limite para Martingais. Começamos a primeira parte da tese apresentando a Teoria de Martingais, introduzindo o conceito de esperança condicional e suas propriedades. Desta forma poderemos descrever o que é um Martingal, mostraremos alguns exemplos, e exporemos alguns dos seus principais teoremas. Na segunda parte da tese vamos analisar o Teorema Central do Limite para variáveis aleatórias, apresentando os conceitos de função característica e convergência em distribuição, que serão utilizados nas provas de diferentes versões do Teorema Central do Limite. Demonstraremos três formas do Teorema Central do Limite, para variáveis aleatórias independentes e identicamente distribuídas, a de Lindeberg-Feller e para uma Poisson. Após, apresentaremos o Teorema Central do Limite para Martingais, demonstrando uma forma mais geral e depois enunciaremos uma forma mais específica a qual focaremos o resto da tese. Por fim iremos discutir as taxas de convergência no Teorema Central do Limite, com foco nas taxas de convergência no Teorema Central do Limite para Martingais. Em particular, exporemos o resultado de [4], o qual determina, até uma constante multiplicativa, a dependência ótima da taxa de um certo parâmetro do martingal.
This dissertation is devoted to the study of the rates of convergence in the Martingale Central Limit Theorem. We begin the first part presenting the Martingale Theory, introducing the concept of conditional expectation and its properties. In this way we can describe what a martingale is, present examples of martingales, and state some of the principal theorems and results about them. In the second part we will analyze the Central Limit Theorem for random variables, presenting the concepts of characteristic function and the convergence in distribution, which will be used in the proof of various versions of the Central Limit Theorem. We will demonstrate three different forms of the Central Limit Theorem, for independent and identically distributed random variables, Lindeberg-Feller and for a Poisson distribution. After that we can introduce the Martingale Central Limit Theorem, demonstrating a more general form and then stating a more specific form on which we shall focus. Lastly, we will discuss rates of convergence in the Central Limit Theorems, with a focus on the rates of convergence in the Martingale Central Limit Theorem. In particular, we state results of [4], which determine, up to a multiplicative constant, the optimal dependence of the rate on a certain parameter of the martingale.

ENGLISH ABSTRACT: Case Report - A case is described of central oxygen pipeline failure that occurred at a large academic hospital and its subsequent implications for managing the situation. Literature review - The literature review undertaken focused on the current state of affairs with regards to anaesthetic staff's knowledge of and preparedness for the management implications of central oxygen pipeline failure. The events I describe below demonstrate a significant deficiency in the staff’s understanding of and training for the crisis, which should be remedied to improve patient safety. Specific measures are suggested in the literature to prevent such incidents and guidelines are available to manage central oxygen pipeline failure. These are reviewed in this study. Recommendations - This study attempts to bring together the most critical aspects that need to be addressed to safely manage similar future incidents. Prevention should include measures to implement clearly stated disaster management plans and increased awareness with regards to the medical gas pipeline system (MGPS), simulation training, efficient alarm systems, personally conducted routine evaluations of equipment and emergency backup systems by anaesthesiologists and effective communication between hospital staff. Careful planning and successful coordination during maintenance and modification of the medical gas pipeline system, using piston-type or air-driven, rather than oxygen-driven, ventilators and optimal design of the hospital bulk oxygen system can contribute to reduce risks. In the event of central oxygen pipeline failure a specific sequence of actions should be taken by the anaesthesiologist and a clear institutional operational policy is described.

Daar word ook gekyk na die praktiese gevolge met betrekking tot die hantering van die situasie. Literatuurstudie - 'n Literatuurstudie is aangepak met die doel om te fokus op die huidige toedrag van sake betreffende narkosepersoneel se kennis en paraatheid in die hantering van sentrale suurstoftoevoerversaking. 'n Wesenlike gebrek aan begrip en opleiding aangaande hierdie onderwerp is geïdentifiseer – areas wat, met die nodige aandag, verbeter kan word ten einde die welstand van pasiënte te verseker. Spesifieke voorkomende maatreëls en hanteringsriglyne word voorgestel deur die literatuur en word gevolglik hersien in hierdie studie. Aanbevelings - Hierdie studie poog om kernaspekte aan te raak ten einde soortgelyke toekomstige voorvalle veilig en optimaal te kan hanteer. Voorkomende maatreëls behels onder meer die daarstelling van duidelik verstaanbare noodplanne, verbeterde bewustheid aangaande die mediese gaspypsisteem, simulasie-opleiding, doeltreffende alarmstelsels, effektiewe kommunikasie tussen hospitaalpersoneel, sowel as narkotiseurs wat self roetine-evaluasies van hul narkosetoebehore en -noodtoerusting uitvoer. Noukeurige beplanning en neweskikking tydens herstelwerk of werk aan die mediese gaspypsisteem, die gebruik van suierventilators (of dan lugaangedrewe in plaas van suurstofaangedrewe ventilators) en die optimale uitleg van 'n hospitaal se suurstoftoevoer, kan bydra om die risiko's te beperk. In die geval van sentrale suurstoftoevoerversaking behoort die narkotiseur stapsgewyse aksie te neem. 'n Duidelike institusionele noodbeleid word ook omskryf.

Abstract:

Mestrado em Mathematical Finance
Um dos teoremas mais importantes da Teoria da Probabilidade é o Teorema do Limite Central. Este afirma que se Xn é uma sequência de variáveis aleatórias então as somas parciais normalizadas convergem para a distribuição normal. Além disso a ausência de pré condições faz-nos perguntar-nos se generalizações são possíveis. Particularmente neste manuscrito vamos focar-nos em duas questões: Existe uma taxa de convergência (universal) para o Teorema do Limite Central? Além disso em que circunstâncias podemos aplicar o Teorema do Limite Central? O teorema de Continuidade de Lévy afirma que a convergência em distribuição é equivalente à convergência nas funções características. Além disso quando aplicamos as expansões de Taylor a funções características ficamos com um polinómios com os momentos da variável como coeficientes. Por estas razões no nosso caso fazer os cálculos com funções características é preferível. Pelo teorema de Berry Essen podemos, de facto, encontrar a taxa de convergência que procuramos. E pelo teorema de Lindeberg e condição de Lyapunov podemos descobrir que o Teorema do Limite Central pode aplicar-se a sequências que não são identicamente distribuídas. Finalmente, utilizando o teorema ergódico vamos explicar como processos estocásticos estão relacionados com a teoria ergódica. Com isto vamos mostrar como este teorema pode ser utilizado pata encontrar um resultado quando a sequencia não é independente.
One of the most important theorems of Probability Theory is the Central Limit Theorem. It states that if Xn is a sequence of random variables then the normal- ized partial sums converge to a normal distribution. This result omits any rate of convergence. Furthermore the lack of assumptions makes us wonder if some gener- alizations are possible. Particularly in this essay we will focus on two questions: Does it exist a (uni- versal) rate of convergence for the Central Limit Theorem? Furthermore in which circumstances can we apply the Central Limit Theorem? The Lévy Continuity Theorem states that convergence on distribution functions is equivalent to convergence on characteristic functions. Furthermore when we ap- ply Taylor expansions to characteristic functions we get a polynomial with the mo- ments as coefficients. For these reasons, on our case computing with characteristic functions is preferable. By the Berry Essen Theorem we can in fact find the rate of convergence we are looking for. And by the Lindeberg Theorem and Lyapunov Condition we find that the Central Limit Theorem applies to sequences that are not identically distributed. Finally, using the Ergodic Theorem we will explain how stochastic processes are related to Ergodic Theory. With this we will show how this theorem can be used to find a result when the sequence is not independent.
