Full textFrom a resolutely classificatory perspective, this thesis proposes a multidimensional analysis of the subclass of French discourse markers which have the particularity of starting with “si” : si je veux, si tu veux / si vous voulez, si on veut, si tu permets, si tu me permets, si vous permettez, si vous me permettez, si je puis / peux dire, si on peut dire, si j’ose dire and si on ose dire. The multidimensional aspect of the study is due to the fact that these markers are polyfunctional: the same unit, in fact, can, for example, sometimes fulfill the function of softener, sometimes that of hardener. The study we propose is structurally multidimensional in that it articulates an approach that is both diachronic and synchronic. In diachrony, we first show the periods in which the markers appeared and then propose a detailed positional and combinatorial analysis. In this same diachronic perspective, we also deal with the question of the selection of the French verb dire for the markers being formed with this archiverb, the syntactic pattern at the origin of the studied units effectively evolving from the Si + Person + Verb scheme to the Si + Person + Verb + (Dire) scheme. To do this, we used the new functionalities of the Frantext 2 database and, within the framework of this exploitation, we set up a methodology that we describe and whose results we present. In synchrony, and on the basis of the exploration of several oral corpora, we offer a focus on two frequent, noticed and remarkable markers in modern and contemporary French, namely si tu veux / si vous voulez and si je puis dire. This approach ultimately allows us to highlight the existence of the French pragmatic-modal couple of vouloir/ pouvoir
Okiye, Waais Idriss. "Analyse multidimensionnelle de la pauvreté : le cas de Djibouti." Thesis, Bourgogne Franche-Comté, 2017. http://www.theses.fr/2017UBFCB001/document.
Full textThe aim of this thesis is to propose and develop the various multidimensional measures of poverty. There is a consensus on the multidimensional nature of poverty. Scientists, policy makers and development professionals agree that the monetary dimension (lack of income) is inadequate to represent poverty. On the basis of the work of Sen (Nobel Proze of Economics), particularly on the capability approach, we propose four different measures of poverty. The first one is a monetary measure based on the utilitarian approach ; the second is a subjective measure founded on household experience ; the third is a multidimensional axiomatic measure and the final one is a non-axiomatic measure based on the theory of fuzzy sets. They are implemented using survey data EDAM3-IS (Djiboutian Survey of Households 2012). The esults fall within the framework of economic growth in Djibouti. However, all the measures used have shown great disparities between the capital and the regions in terms of basic infrastructure and household welfare. Each method produced results with different interpretations of the determinants of poverty. This does not mean that there is one method being better than the other but rather each approach, in a particular context, may be more relevant. Thus, identifying the poor by applying the different measures of poverty gave us a clear-cut profile, which implies that the decision-maker must first set the aim in view in the implementation of anti-poverty policies. It can be emphasized that the inclusion of a subjective weighting in the process of measuring of poverty is one of our contributions towards the development of multidimensional measures of poverty

Full textDuring the last decade, the mathematical and statistical study of sparse signal representations and their applications in audio, image, video processing and source separation has been intensively active. However, exploiting sparsity in multidimensional processing contexts such as digital communications remains a largely open problem. At the same time, the blind methods seem to be the answer to a lot of problems recently encountered by the signal processing and the communications communities such as the spectral efficiency. Furthermore, in a context of mobility and non-stationarity, it is important to be able to implement adaptive processing solutions of low algorithmic complexity to ensure reduced consumption of devices. The objective of this thesis is to address these challenges of multidimensional processing by proposing blind solutions of low computational cost by using the sparsity a priori. Our work revolves around three main axes: sparse principal subspace tracking, adaptive sparse source separation and identification of sparse systems. For each problem, we propose new adaptive solutions by integrating the sparsity information to the classical methods in order to improve their performance. Numerical simulations have been conducted to confirm the superiority of the proposed methods compared to the state of the art

Full textThe new field of precision medicine is revolutionizing current medical practice and reshaping future medicine. Precision medicine intends to put the patient as the central driver of healthcare by broadening biological knowledge and acknowledging the great diversity of individuals. The prediction of physiological and pathological states in patients requires a dynamic and systemic understanding of these interactions. Inborn errors of metabolism (IEM) are genetic disorders resulting from defects in a given biochemical pathway due to the deficiency of an enzyme, its cofactor or a transporter. IEM are no longer considered to be monogenic diseases, which adds another layer of complexity to their characterization and diagnosis. To meet this need for faster screening, the metabolic profile can be a promising candidate given its ability in disease screening, biomarker discovery and metabolic pathway investigation. In this thesis, we used a metabolomic approach which is particularly relevant for IEM given their basic pathophysiology that is tightly related to metabolism. This thesis allowed the implementation of an untargeted metabolomic methodology based on a multidimensional analytical strategy including high-resolution mass spectrometry coupled with ultra-high-performance liquid chromatography and ion mobility. This work also set a methodology for preprocessing, analysis and interpretation of the generated data using experimental design and multivariate data analysis. Finally, the strategy is applied to the exploration of IEM with mucopolysaccharidoses as a proof of concept. The results suggest a major remodeling of the amino acid metabolisms in mucopolysaccharidosis type I. In summary, metabolomic is a relevant complementary tool to support the genomic approach in the functional investigations and diagnosis of IEM

Full textDropout from undergraduate university programs has attracted researchers’ attention. However, it is difficult to understand persistence in undergraduate studies due to the complexity of this phenomenon and the large number of associated factors. Persistence in undergraduate studies seems to be related to individual, contextual factors and the financial situation during the studies. Until now, these factors were studied independently, and to our knowledge, no study attempted to take into account the combined effect of these factors in the same model. In this doctoral dissertation, our goal is to understand the relevant determinants of undergraduate persistence based on expectancy-value theory (Eccles et al., 1983), the interactional model (Tinto, 1975) and the financial impact model (Paulsen & St. John, 1997; St. John, 1990; St. John et al., 1994). The purpose of this dissertation is thus to validate a model of persistence. It includes two studies. A retrospective study that allows the assessment, from the previous experience of students (n = 731), of factors that played a role in persistence. Also, a prospective study was conducted over a 6 months period in a sample of students pursuing a bachelor’s program at Laval University (n = 3 084). Findings of the retrospective study indicate that the financial variables, previous academic performance, and the fact of obtaining a college degree (Cégep) predict students’ persistence. In the prospective study, among the factors considered, competence beliefs, expectancies for success, and the intrinsic value contribute in the prediction of intention to persist. Only two interactional factors predict the intention to persist: peer-group interactions and the institutional and goal commitments. For the second measuring time embedded in the prospective study, we observed that intention to persist, faculty concern for student development and teaching, academic and intellectual development and the fact of obtaining a college degree (Cégep) predict persistence. Theoretical, methodological, and practical implications are discussed and directions for further research are proposed.
Gabsi, Chaker. "Analyse économique de la pauvreté en Tunisie : approche monétaire et multidimensionnelle." Thesis, Nice, 2016. http://www.theses.fr/2016NICE0016/document.
Full textThe aim of this thesis is to analyze the evolution of poverty and identify the socio-economical groups as well as the dimensions that contribute to it in Tunisia following a monetary approach and also a multi-dimensional one. For this reason, I adopt a method which consists in using the approach of stochastic dominance and the theory of fuzzy sets. That is to say, I adopt some of the different methods which have been adopted in the previous studies that were interested in Tunisia. Three main conclusions emerge from the exploitation of data based on two national surveys of the budget and the consumption of households 2005, 2010 and another national survey of the family health 2006. In fact, the first one reveals the decrease of poverty at the national level despite that there are disparities that still persist between rural and urban areas and between the coastal regions and the regions of the interior as well. The second survey puts in evidence that the effects of redistributive policies in Tunisia have not accelerated the pace of poverty reduction. As for the third survey, it suggests that taking into account the multi-dimensional aspect of poverty reveals the existence of other important dimensions in relationship with poverty that constitute an obstacle to a decent life for the Tunisian households

Full textMeat quality includes criteria of different importance depending on the animal species. Meat quality is a significant economic factor in pork production, and numerous publications have shown that it is strongly influenced by the interaction between genetic type (especially the halothane gene (Hal) and Napole yield gene (RN)), breeding conditions, and pre-slaughter and slaughter conditions of animals. The European Union, longtime leader of the globalmarket of pork and pork products, now faces increasing competition from other countries,including Brazil, the United States and China. This thesis project is part of a multidisciplinary European project on improving the quality of pork and pork products for the consumer. One of the modules of this project is dedicated to the integration of existing and upcoming data to produce a model for predicting technological and sensory pork quality, based on animal,production, and slaughter information. The objective of this thesis is to synthesize existing knowledge derived from bibliographic and experimental data relating to the main factors influencing meat quality within a meta-analysis, which is a statistical approach combining the results of a series of independent studies on a given problem. The results of this work have confirmed the effect of the halothane gene, as well as fasting, transport and lairage times on most of the analyzed parameters of technological pork meat quality. Indeed, our meta-analysis confirmed the significant effect of the halothane gene on all the analyzed meat quality attributes. However, the halothane gene effect was associated with the breed effect only for the following variables: L*-value (reflectance), b*-value (yellowness) and DL (drip loss). Slaughter weight contributed significantly only to the explanation of differences in ultimate pH between homozygous genotypes: NN and nn. Regarding the preslaughter conditions, the results of our meta-analysis showed that fasting time had a significant effect on pHu and DL measured in longissimus muscle. While, lairage affected only the pHu in semimembranosusmuscle. Interestingly, we found that DL was the lonely attribute significantly affected by transport time and its interaction with fasting time. The significant effect of the vitamin E supplementation on lipid oxidation process in pork and, therefore, affect the technological meat quality, was demonstrated by using a non linear meta-analytic regression model. Statistically, the comparison between the Bayesian and frequentist meta-analytic approaches has highlighted the ability of the hierarchical Bayesian model to reduce uncertainty in parameter estimates, especially when the number of studies included in the meta-analysis is relatively limited. In addition to the meta-analytic approach, an exploratory study by multivariate analyses was performed to identify the correlations among a large number of variables structured into separate groups. Our results showed that the variables which discriminated the five classes of breed (Large White and Basque pigs) x rearing system (conventional, alternative and extensive) were the same as those discriminating individuals. Indeed, a first group composed of transcriptomic, chemical and technological variables discriminated breeds. Slaughter reactivity variables discriminated rearing systems, especially the Basque pigs reared in the extensive system

Full textThis thesis is at the interface of, on one hand, prosodic phonetics and phonology and, on the other hand, of discourse analysis. More specifically, this work aims to describe, explain and compare the phenomena related to prosodic marking of the narrative structure of discourse in French.Our methodology is based on the analysis of a 58-minute-long corpus of 20 natural speech narratives by French native speakers, who were asked to tell the content of comics without any warning. On one hand, the corpus was aligned with phonemic, syllabic, lexical and inter-pausales units levels; acoustic-phonetic data was then extracted automatically with all levels of granularity. On the second hand, we applied a narrative segmentation according to the criteria of Labov’s evaluative model (1972) which is based on semantic and informational criteria.The mapping of these two analyzes was made on two structural levels: global and local. The results showed the existence of a link between the narrative sequential segmentation and long-term variations of melody, speech rate and intensity. However, these results did not show an effect in the short term prosodic variations related to the structural segmentation. Furthermore, we demonstrated that for each prosodic domain, the realization of a reset at the narrative junction.Without advocating one relationship between prosodic and discursive organization structure, our results demonstrate, that prosody, as well as syntax or semantics, takes part in marking informational continuity and discontinuity

Full textThe consequences of the 2008 financial crisis led the worldwide regulatory authorities to coordinate their efforts to establish a new global banking regulation with the aim of strengthening the financial system as a whole and preventing potential future crises. However, the amendments put in place at the jurisdictional levels underline the need to establish an appropriate regulation alongside a general framework. In this way, we highlight the importance of regulatory standards adjusting to economic actors, economic instruments and the economic environment. As a first step, we confirm the relevance of a regulatory measure allowing a reduction in capital requirements associated with lending to small and medium-sized enterprises. The results regarding the consistency and effectiveness of this Supporting Factor promote the introduction of regulation adjusted to the risk generated by economic players. Second, by highlighting interactions between funding liquidity and market liquidity, emerging only during periods of stress, we demonstrate the benefits of requirements developed in a countercyclical form, which banks can release and use when facing with a liquidity shock. Finally, we show the importance of more risk-specific regulation of funding tools, such as credit lines. Their concentration, volatility and funding limits confirm the need for an appropriate regulation of these multi-risk instruments. While the crisis enabled a standardization of regulatory requirements at the global level, we emphasize the advantages of a more specific banking regulation, with aligned global requirements to which suitable requirements are added when necessary

Full textThis thesis focuses on variables selection on linear models and additif functional linear model. More precisely we propose three variables selection methods. The first one is concerned with the selection continuous variables of multidimentional linear model. The comparative study based on prediction loss shows that our method is beter to method of An et al. (2013) Secondly, we propose a new selection method of mixed variables (mixing of discretes and continuous variables). This method is based on generalization in the mixed framwork of NKIET (2012) method, more precisely, is based on a generalization of linear canonical invariance criterion to the framework of discrimination with mixed variables. A comparative study based on the rate of good classification show that our method is equivalente to the method of MAHAT et al. (2007) in the case of two groups. In the third method, we propose an approach of variables selection on an additive functional linear model. A simulations study shows from Hausdorff distance an illustration of our approach

Full textA successful business is often conditioned by its ability to identify, collect, process and disseminate information for strategic purposes. Moreover, information technology and knowledge provide constraints that companies must adapt : a continuous stream, a circulation much faster techniques increasingly complex. The risk of being swamped by this information and no longer able to distinguish the essential from the trivial. Indeed, with the advent of new economy dominated by the market, the problem of industrial and commercial enterprise is become very complex. Now, to be competitive, the company must know how to manage their intangible capital. Competitive Intelligence (CI) is a response to the upheavals of the overall business environment and more broadly to any organization. In an economy where everything moves faster and more complex, management Strategic Information has become a key driver of overall business performance. CI is a process and an organizational process that can be more competitive, by monitoring its environment and its dynamics. In this context, we found that much information has strategic significance to the relationship: links between actors in the field, semantic networks, alliances, mergers, acquisitions, collaborations, co-occurrences of all kinds. Our work consists in proposing a model of multivariate analysis dedicated to the IE. This approach is based on the extraction of knowledge by analyzing the evolution of relational databases. We offer a model for understanding the activity of actors in a given field, but also their interactions their development and strategy, this decision in perspective. This approach is based on the designing a system of generic information online analysis to homogenize and organize text data in relational form, and thence to extract implicit knowledge of the content and formatting are adapted to non-specialist decision makers in the field of knowledge extraction

Full textInformation retrieval tools are faced with the constant increase of data both in volume and in dimensionality and the traditional list of results no longer meet many applications' requirements. New visual representation techniques are needed. These new techniques have to provide an overview of large and multidimensional data sets that gives insights into the underlying trends and structures. They must also be able to represent, in detail, portions of the original data from different standpoints. The aim is to assist the user in her data exploration task by designing a shrewd link between general and local views, that maintains her mental map. In order to achieve this goal, we develop a combination of data analysis techniques that identify pertinent portions of data as well as information visualization techniques that intuitively and dynamically explore these portions of data in detail. In addition, a formalization of the visualization process is needed. We introduce a formal frame that is used to specify visualizations from data structures. Concretely, the solution proposed is an original navigation method that combines techniques from Formal Concept Analysis (FCA) and Multi-Dimensional Scaling (MDS) visualization approaches to suggest navigation paths in the data. This method is based on the "overview + detail" paradigm: One component is an overall view which summarises the underlying structure of the data. A second component is a local view showing an element of the overall view in detail. We take advantage of the classification skills of the Galois lattice by using it as the overall view that reveals the inner data structure and suggests possible navigation paths. The local view uses Multi-Dimensional Scaling to display the objects in the extent of a selected concept. We illustrate and discuss the pertinence of our method on concrete data sets, provided by our industrial partners, and show how hybridisation of FCA and traditional data visualization approaches, which have sometimes been considered distinct or incompatible, can be complementary

Full textRanked 162nd in the world out of 183, Togo is one of the least advanced countries in the world. Shaken by a huge political crisis in the 90’s with dramatic social and economic consequences, the country has had positive GDP growth rates since 2006. However, this performance is still not enough to considerably alleviate the country’s multiform poverty. This dissertation aims to measure two approaches of poverty: the monetary one and basic needs. The measuring tools are: Foster Greer Thorbecke (FGT) poverty indices once a poverty line is determined, Multiple Correspondance Analysis (MCA) used to construct a Composite Poverty Indicator (CPI) and finally econometric estimations. Having introduced some targeting policies, a special attention is paid to micro-finance. Statistical results have shown evidence that, despite the high level of loan repayment by group lending members, they remain non-monetary poor. It is also noticed that the repayment performance isn’t linked to any improvement of the credit group member’s monetary situation, but rather to the very nature of group lending technology

Full textThis study analyses the multidimensional poverty of the women in Haiti and the impact of a resourcefulness generating activities of income, KOFAVAC, on the living conditions of those. The analytic results of the survey carried out near the women reveal that poverty affects all the dimensions of their life. The determinants of poverty are at the same time factors related to the socio-demographic and economic characteristics of the women life and her household: the size of the household, the number of children who are not attended school, the number of adults without profession and which do not undertake any gainful activity and the level of staffing off land and animals breeding. The impossibility of satisfying the needs for the household is perceived by the women as being the first sign of poverty and the factor determinant of their incapacity to remain in the system credit/saving KOFAVAC. The impact of KOFAVAC, as bearing an additional income is very weak; its support in terms of contribution to the satisfaction of the needs of food and schooling for the children is recognized by the women. Therefore, the creation of jobs and free education appear among the priority actions that the Haitian Government must undertake in Chansolme for improvement of the conditions of the population according to women's. In the same way, the search of new generating activities of incomes, assistance for housing, transformation of new products and the search for new markets are proposed by women for a better support of KOFAVAC.

Full textIn this thesis we propose new parametric models in signal and image processing based on the Wold decomposition of stationary stochastic processes. These models rely upon several theoretical results from functional and harmonic analysis, wavelet analysis and the theory of stochastic fields, The first chapter presents the theoretical background of the linear prediction for stationary processes and of the Wold decomposition theorems in 1-D and n-D. It is shown how the different parts of the decomposition are obtained and represented, by the means of the unitary orbit representation of stationary processes, the Kolmogorov canonical model and Szego-type extensions. The second chapter deals with a spectral factorisation approach of the power spectral density used for the parameter estimation of Moving Avergage (MA), AutoRegressif (AR) and ARMA models. The method uses the Poisson integral representation in Hardy spaces in order to estimate an outer transfer function from its power spectral density. - Simulators for Rayleigh fading channels (1-D). - A scheme for the Wold decomposition for texture images (2-D). In the third chapter we deal with hybrid models for image representation and compression. We propose a compression scheme which jointly uses, on one hand, Wold models for textured regions of the image, and on the other hand a wavelet-based approach for coding the 'cartoon' (or non-textured) part of the image. In this context, we propose a new algorithm for the decomposing images in a textured part and a non-textured part. The separate parts are then coded with the appropriate representation

These two techniques, little explored so far in this area, may be of interest by simplifying sampling and allowing a more comprehensive analysis of markersWork on the preconcentration chip has shown that micropreconcentrators manufactured in the laboratory sample and inject model gas mixtures and expired air samples with variability close to laboratory systems. In addition, our work has shown that these microproconcentrators have two major advantages in reducing the necessary sample volumes and integrating into simple, portable and battery-powered systems. In order to illustrate their interest in a simple real-world case, we used these microproconcentrators to study three smoking markers in the exhaled breath of three smokers and three non-smokers, and to track the kinetics of these compounds in a person’s breath. Finally, we performed preliminary integration work in dedicated samplers in order to exploit the benefits of micropreconcentrators for the collection of breath and attempt to obtain a single expiratory sampling.We then chose and reproduced a simple fluidic modulator architecture, relevant for miniaturization, based on a Dean's switch. We showed that this modulator described in 2016 was compatible with a thermodesorption injection and compared its performance to GC for the analysis of the same breath sample. This has shown that this architecture is of interest in modulating very volatile exhaled compounds which allows many coelution lifts. Finally, we showed, thanks to experimental designs, that the improvement of the performances of this modulator required a meticulous control of the parameters.Finally, we confronted our tools with samples of a patient suffering from a rare disease, phenylketonuria. Samples of urine head space and exhaled air from the patient were taken. The results, incomplete at this stage, are discussed in the manuscript

Full textThis study aims to show the possibilities offered by the PCA in the description of the physicochemical quality of a river and to evaluate the anthropic contribution of the dissolved organic matter (DOM) to the degradation of this quality. Being based on an analytical follow-up in 13 stations of Vienne river, it was shown that the study of the bivaried correlations allows to reveal perturbations of the environment, by the organic discharges. Various PCA made it possible to specify with a good objectivity the spatial and temporal changes in water quality in Vienne river. In addition, dispersion in the PCA plan of the individuals representative of the same station can be used to evaluate the disturbances related to the anthropic contributions. In order to acquire a better knowledge of the evolution of the DOM of a rivers, research were carried out on the study of OM extracts isolated through various analytical techniques from characterization

Full textContext: The principal risk factor for lung cancer is by far tobacco smoke, however occupational exposures deserve a special interest because they are the 2nd main etiology of this cancer. Little information is currently available on the relationship between lung cancer risk and occupational exposure to solvents that are widely used in several industries. Certain jobs such as painters, who are particularly exposed to solvents, are known to be at increased risk of lung cancer, but the causative agent is still unknown or unproven.Objectives: The aim of the present work was the evaluation of the role of occupational exposure to different organic solvents on lung cancer risk. Initially we studied the effect of occupational exposure to chlorinated solvents; then the analysis integrated exposure to two other solvent families, namely fuels and petroleum solvents and oxygenated solvents, always taking into account the main risk factors for lung cancer, including cigarette smoking and occupational exposure to asbestos.Population and methods: This work was based on a large population-based case-control study, ICARE. Detailed data on the lifelong occupation was collected. A total of 2,926 cases of lung cancer (2,276 men and 650 women) and 3,555 controls (2,780 men and 775 women) were included. Exposure to solvents was assessed by job exposure matrices, developed separately for each substance by industrial hygienists. In addition, exposure to certain solvents was directly reported by subjects in the questionnaire. First we followed a classical statistical regression analysis approach to investigate the role of chlorinated solvents. In the analysis that included three families of solvents, we followed a multidimensional complex methodological approach. Bayesian profile regression method enabled us to overcome traditional analysis limits due to high multicollinearity between solvents.Results and conclusions: The analysis focused on chlorinated solvents suggested an association between lung cancer and occupational exposure to perchloroethylene (PCE), especially in women. While, no association with lung cancer risk could be demonstrated in the second analysis, incorporating the three families of solvents (chlorinated, petroleum and oxygenated). However, as we had increased the specificity of exposure definition, PCE was not included in the studied solvents anymore, preventing us from confirming or denying the association suggested above. Although solvents were not associated with lung cancer, we identified two groups of subjects whose risk of lung cancer was higher than the average. In particular, one of these groups included a high concentration of painters, however our analysis does not advocate the role of solvents to explain this excess. Despite the lack of association between solvent exposure and risk of lung cancer, the Bayesian approach allowed us to analyze the effect of joint exposure to a relatively large number of substances, which is a fairly common situation in occupational exposures. Thanks to this innovative method, our intention is now to look at the role of joint exposure to substances recognized as carcinogenic for the lung such as asbestos, silica dust and diesel engine exhaust, that are frequently found for instance in construction industry

Full textFrom 1980 to 2000, the education quality in sub-Saharan Africa decreased gradually under multiple influence. Already characterized by a low level of internal efficiency, schooling and learning outcomes, themselves dotted with regional disparities, gender and unequal access, the transformations of the education sector will be accentuated by the rise in school-age population. To deal with this situation, Governments adopt a curriculum reform at the beginning of 2000 through the Skills-Based Approach.Attached to social justice issues and learning quality, the Skills-Based Approach’ implementation has not always been conducive to rigorous evaluation in the economic literature. Due this situation, our thesis tempts to analyze its transfer and impact by comparing the Ivorian and Senegalese experiences. To achieve this goal, our work has been based on mix methods. In doing so, chapters 1 and 2 successively identify each system particularities and then the curriculum determinants and main objectives. Consecutively, chapter 3 analyzes its transfer, articulation and effectiveness in each educational system, whereas Chapter 4 assesses its impact on internal efficiency and learning quality by a multilevel model.By comparing the results from each methods, we observe that the Skills-based Approach does not explain internal efficiency improvement, which is rather the consequence of inter-cycle transition rules revision. Concerning learning quality, the econometric analysis corroborates the transfer assessment, and suggests a new approach to educational product quality: it insists to pay particular attention to the way in which educational policy is conceived and disseminated
