Full textMultiple Sclerosis (MS) is a chronic inflammatory disease of the central nervous system, leading to significant disability among affected individuals. The treatment landscape for MS has evolved over the past decades, with the introduction of various high-efficacy disease-modifying therapies (DMTs). This thesis investigates the long-term safety and efficacy of these therapies, particularly in the context of the Middle East and North Africa (MENA) region. The research involves a comprehensive analysis of treatment accessibility, barriers to therapy, and the clinical outcomes of MS patients in this region. It includes five studies that explore the availability and accessibility of DMTs, the impact of the COVID-19 pandemic on MS management, and the comparison of natalizumab with anti-CD20 monoclonal antibodies. The findings underscore significant disparities in treatment access and the need for targeted regional strategies to improve MS management. Furthermore, the research contributes to the global understanding of MS by providing insights into the long-term outcomes of high-efficacy DMTs in a real-world setting

Full textCurrently, econometric modelling's contribution, both to economic forecasting and economic policy valuation, is signifiant. However, models term (about five years) is sometimes inadequate. It it possible to extend it? Specifications properties in a long term perspective, and their compatibility, were theoretically studied. Those works pointed out the relationship between long term properties of macroeconomic models and results of theory of growth. So far, questions raised by long-run modelling practise can be expressed using theory of growth's framework: existence and properties of a steady state growth path, and its stability. First, models must provide an analytical framework that allows organisation of inputs contribution to growth. From this point of view, production function is the significant concept. It is widely studied, both using a putty-putty assumption, and a vintage approach. Simulation experiments are used to fith the practical consequence of our results. Yet, it will not do simply to superimpose a model of the business cycle on an equilibrium growth path. In the short run, disequilibriums are explicitly registered in models. Theoritical models of economic growth with disequilibrium can provide interesting exploratory sketchs, that could allow to improve long term properties of econometric models. Concerning disequilibrium on the financial market. .

Full textThe research carried out during the PhD deals with winter windstorms with high economic damage potential in Europe and can be divided in two parts. The first part aims at quantifying the impact of climate change on European winter windstorms and relies on datasets covering long periods of time (>30 years) either in the past or in the future. The objective of the second part is to forecast potential losses and claims associated with an upcoming extreme windstorm by using forecast data updated every six hours. The overall objective of the first part is to provide a medium-term view of what could be the winter windstorms in Europe during the 21st century. It thus completes the short-term vision of the risk given by the Catastrophe Models used by the (re)insurers to assess the cost of the risk on their portfolio. A new methodology has been developed to define the damage potential associated with European winter windstorms. The novelty of the methodology relies in the use of several variables capturing different spatiotemporal scales and the coupling that exists between variables during the cyclogenesis. Seeking for events sharing a similar intense signature simultaneously in the relative vorticity at 850 hPa, the mean sea level pressure and the surface wind speed lead to the detection of a small group of events. Comparing the number of events that belong to this group and their intensity in reanalysis datasets and different simulations of the future climate can provide enough information to insurance companies on the potential evolution of this hazard in a future climate. A first paper on the methodology has been accepted in the journal of Natural Hazard and Earth Science System.The methodology has been applied to the datasets provided by Global Climate Models (GCM) participating to the CMIP5 project. The goal is to assess the ability of GCMs to reproduce winter windstorms in Europe and the potential impact of climate change on the frequency and intensity of such events. A second paper presenting the results obtained from this second study will be submitted.The second part of the PhD focuses on the project Severe WIndstorms Forecasting Tool (SWIFT). The objective is to develop an early warning tool that detects an upcoming winter windstorms in meteorological forecasts updated every six hours and provides interested AXA entities with an alert on the upcoming windstorm as well as an estimate of the potential losses and claims.The tool has been developed in parallel of the research project and consists in two modules. In the first module, particularly intense systems are detected in meteorological forecasts and the associated gust footprint is extracted. In the second module, wind speeds are translated into a loss and a number of claims thanks to vulnerability curves. When a system is detected, an alert is sent with the appropriate information on the event propagation and the associated loss. The tool has been running automatically for the 2013 – 2014 winter season and detected most of the events that passed over Europe

Full textBackground: The low frequency of spontaneous intracerebral haemorrhage (ICH) and its high mortality rate may explain the paucity of data in long term outcomes. The main objective was to study long term prognosis of ICH through the prism of their natural history.Methods: Our study populations were based on the PITCH (Prognosis of IntraCerebral Haemorrhage) cohort which is an observational study that included consecutively adults admitted at the Lille University Hospital for spontaneous ICH between 2004 and 2009. We aimed to determine (i) the incidence of new onset dementia and its clinical and radiological predictive factors; (ii) the prevalence of cortical superficial siderosis (cSS) and its associated factors; (iii) predictive factors of recurrent ICH.Results: We showed that the risk of new onset dementia is substantial after spontaneous ICH. Predictive factors of new onset dementia such as ICH lobar location and cSS suggest the implication of underlying cerebral amyloid angiopathy. We found that one out of five patients had cSS on baseline MRI. cSS was a strong predictive factor of recurrent ICH. Conclusion: These findings are of immediate clinical relevance in the management of ICH patients and will allow to adequately inform patients and caregivers. These results may provide additional information on ICH recurrence risk assessment and may contribute to the development of future therapeutic strategies

Full textFrom a global perspective, a low-carbon path to development driven by a growth of nuclear power production raises issues about the availability of uranium resources. Future technologies allowing nuclear reactors to overcome the need for natural uranium will take time to fully deploy. To address these issues, we analyze the conditions of availability of uranium in the 21st century.The first two conditions are technical accessibility and economic interest, both related to the cost of production. We study them using a model that estimates the ultimate uranium resources (amounts of both discovered and undiscovered resources) and their costs. This model splits the world into regions and the resource estimate for each region derives from the present knowledge of the deposits and economic filtering. The output is a long-term supply curve that illustrates the quantities of uranium that are technically accessible as a function of their cost of production. We identify the main uncertainties of these estimates and we show that with no regional breakdown, the ultimate resources are underestimated.The other conditions of availability of uranium covered in our study are related to the market dynamics, i.e. they derive from the supply and demand clearing mechanism. To assess their influence, they are introduced as dynamic constraints in a partial equilibrium model. This model of the uranium market is deterministic, and market players are represented by regions. For instance, it takes into account the short-term correlation between price and exploration expenditures, which is the subject of a dedicate econometric study. In the longer term, constraints include anticipation of demand by consumers and a gradual depletion of the cheapest ultimate resources.Through a series of prospective simulations, we demonstrate the strong influence on long term-price trends of both the growth rate of demand during the 21st century and its anticipation. Conversely, the uncertainties related to the estimation of ultimate resources have limited influence. We also underline the uneven evolution of market shares between regions. Finally, particular changes in supply (production shutdown in one of the regions, for example) or in demand (irregular growth or introduction of new technology) also have a significant influence on the evolution of the long-term price or its cyclicity

Full textNeuroinflammation induced by systemic inflammation or generated in response to acute brain injury has adverse clinical consequences: it is implicated in exacerbation of acute brain injury in humans, for adults as well as for children. Microglia is the main effector of this cerebral inflammatory response, and may present, depending on the situation, a neurotoxic or - on the opposite - anti-inflammatory and regulating profile. To decipher the mechanisms of microglial activation and their consequences is essential for better management of patients.The first part of this thesis focuses on the consequences of neonatal inflammation associated with prematurity on the microglial response in adulthood, in case of new cerebral aggressions such as systemic inflammation or acute brain injury. Relying on a mouse model of inflammation of the preterm infant, we have demonstrated drastic modifications of the microglial transcriptome once these mice are adults. Moreover, when an inflammatory stimulus occurs in adulthood, the microglial activation profile is altered, the peak of pro-inflammatory and immuno-regulatory markers occurring earlier, demonstrating the existence of a memory of the cerebral innate immune system. These changes in the microglial activation profile are accompanied in a model of excitotoxic brain injury by an increase of the white matter lesion size. Melatonin treatment of mice prevents the happening of this worse outcome. In the second part of this thesis, we characterized the microglial activation profile in vitro, in response to stimulation by HMGB1, a damage associated molecular pattern released during cell death and therefore present in acute brain injuries but also in associated extra-cranial injuries. We have shown that the microglial activation profile depends of the kind of HMGB1 used. Microglia exposed to Sigma recombinant form have a proinflammatory transcriptomic profile but a lower release of cytokines in the culture medium. These results highlight the importance of inflammation and microglial activation in the prognosis of brain injuries and offer the opportunity to implement innovative neuroprotective strategies

Full textThe aim of this work was to give arguments in favour of an multiple traces memory model (Versace, Nevers, & Padovan, 2002), in which memory traces are supposed to be distributed over multiple dimensions. According to this model, the descriptive dimensions of knowledge are assumed to be mainly sensorial, motor et emotionnal. Therefore, representation are supposed to be records of the neural states that underlie perception and action. This conception supposes that the presentation of a visual stimulus representing an object activates automatically the various sensory and motor properties which are associated with him. Three series of experiments realized within the framework of this thesis respectively used a short term inter-sensorial (autidory-visual) priming paradigm, a short term sensori-motor priming paradigm and finally a long term inter-sensorial priming paradigm. All these experiments allowed to demonstrate the existence of both fundamental mechanisms of the studied model: the activation of the sensory and motor dimensions of the knowledge and the integration of these elementary dimensions so that appears an elaborated knowledge

Full textIn the last decades with the era of globalisation, air transportation has been playing an important economic role by easing the transportation of people and goods between the different parts of the World and to remote areas within countries. The airports as ground/air intermodal terminals are the ground segment of the air transport system. Sustained investments over long periods of several decades appear essential to maintain or expand airport operations. These investments are in general costly and airport investment planning is an important issue at the local and national levels. The objective of this thesis is to present a long-term planning approach for the investments in national airports networks. A framework for the long-term generation of multimodal transportation demand scenarios at the national level, which insures coherency between the prediction of the different transportation modes and assure compatibility between the predicted air transportation flows between the considered airports, is proposed. Then the central decision problem for long-term resource allocation between the different airports of a national network is formulated as an optimization problem. This model can be solved with different demand scenarios, where extreme scenarios should provide an interval for the necessary financial effort at each stage of the planning horizon for each airport. To solve the resulting optimization problems a Dynamic Programming approach has been considered where the candidate states to be processed at each stage are generated by a Petri Net built from the undated master plans of the airports of the considered network. The proposed approach is illustrated in the case of a large under developed country (Niger Republic)

Full textThe sinusoidal modeling of speech signaIs is usually defined on a "short term" basis, i. E. On successive frames of about 10 to 30 ms. This thesis brings a new contribution to this domain by adding to this traditional level spectral modeling an additionnal level along the temporal axis: we model the trajectories of sinusoidal parameters over durations significantly longer than the short-term frames (several hundreds of ms). Ln this study, we propose to use various long term models based on discrete cosine functions and polynomials. The adjustment to the trajectories is carried out by a weighted minimum mean square error regression, the weights of the regression being determined by perceptive criteria. For this task, a series of iterative algorithms is proposed and tested. The 101 term method is shown to be an efficient and parsimonious approach to describe the dynamics of the speech signal

We show a detail view of changes that have happened in the Cambodian labour market and precising how these changes affect population and economy. The result of labour market analysis will show the quasi non-existing of the labour market and employment policies in Cambodia and that some theoretical framework designed to improving labour market respond partly to the actual situation of Cambodia. This is the reason for which we try to analyse the Cambodian labour market in order to find out all short and long term constraints which lock up the good functioning of Cambodian labour market and which obstruct the application of the theoretical framework. We try finally to view long term strategies for improving labour market and employment situation in Cambodia

Full textThis thesis focuses on long term investments and risk premiums within the French financial market. The results bring evidence supporting placements in long term, risky and productive assets. In terms of portfolio management, this thesis brings several answers regarding the optimal allocation strategies. The first article demonstrates that the French financial market is weak form efficient since we could not reject the random walk hypothesis based on the variance ratio methodology. This first contribution implies that abnormal returns are resulting from risk factors and not from anomalies. Thus, the second article revisits famous asset pricing models and highlights optimal portfolio strategies. We find that value and momentum premiums are persistent in the French market. However, size premium is only observable in extreme book to market and momentum strategies. Moreover, we show that market portfolio choice is sine qua non to models performances and that the latest is surprisingly increasing in times of distress. The third article considers the term structure of risk-return tradeoff. Based on a VAR model, we find that excess annualized standard deviation of stocks excess returns with respect to bonds and bills decreases as we lengthen investment horizon which means that investors may bias their portfolios towards safe assets and neglect additional return. Furthermore, we measured the time diversification effect among stock portfolios by distinguishing small and big capitalizations and prove that it is more profitable to hold small capitalizations than big capitalizations stocks in the long run. These results shed light on inefficient prudential rules from the viewpoint of policyholders on one hand, and, on the other hand, highlight the necessity of implementing measures to revive the markets for small enterprises and facilitate their access to direct financing through the market

Full textThis thesis examines the long-run performance of french firms after seasoned equity offerings. First, we study the long-run operating performance of french companies issuing stocks. Our results suggest that issuing firms experience substantial improvement in operating performance prior to the offering, while the tendency is reserved over the three years after the offering. These results offer evidence consistent with the "window of opportunity" hypothesis explaining the downward drift following a seasoned offering. However, the free-cash flow hypothesis is not confirmed. Second, we test the earnings management hypothesis before seos. We find that issuing firms experience poor earnings performance during the post-offering period. Performance-matched discretionary accruals recorded immediately after seos are positive and that those accruals lead to a decline in post-seo earnings performance. Third, we study the long-run stock returns of french seo firms. Firms issuing during periods of "hot issues" underperform significantly matching firms, whereas firms issuing during periods of "cold issues" do not underperform in the long-run. This effect is more pronounced for small size firms. The results are not sensitive to the methodology

Full textResearch on the commitment has been practised in an organizational context. They show that social changes are favoured more by commitment than persuasion in the short term. This research, centred on purely safety behaviour attitudes relative to the industrial environment, was implemented in two ways: the persuasive communication stratégy and the commitment stratégy. It verified that communication is not only effective in the short term but can also be prolonged in the long term. While persuasive communication brings no change at all. It seems that people only intervene in general ways (security decisisons, safety improvements) and not in their attitudes concerning the direct workloads of the employees. This shows the functional specificity of commitment in organizations

Full textEconomic growth and its driving forces have been the maintopic preoccupying economic researchers since long time in macroeconomic branch. Public investment in human capital through educational system plays an ultimate role in boosting economic growth and development, this role has taken a place since the innovative dawn of endogenous growth theory. The focus and efforts of investing in human capital could be destabilized by the global and recent return of sovereign debt crisis in several countries, which continues its rise since theearly 2007, and the after-crisis necessary adjusting policies. Getting back wise policies should be composed of mixture of growth fostering activities, including the investment in human capital, austerity and forbearance.The main purpose of this thesis is to provide new empirical inferences on debt-growth relationship and its interaction with human capital formation. Estimates are carried on a recent and complete data set that spans over 22 years and involves 76 countries worldwide. The range of invested variables encompasses many macroeconomic aggregates such as : GDP annual growthrates, public debt to GDP ratio, and public education expenditure to GDP ratio, average schooling years, inflation rate, and others. Using a superior estimation semi-parametric technic which accounts for some data issues, the empirical results suggest a heterogeneous impact of public debt and education expenditures levels on GDP growth rates. Henceforth, the use of education expenditure in the whole sample is inefficient,where policy makers should adjust and well manage the function of these expenditure in line with the public efforts to reduce debt high levels and rise economic growth. We also show that the use of textual analysis tools in economic studies, such in growth literature, offers a rapid and total lecture of the hidden research trends embodied in the huge empirical and theoretical literature of economic growth
