Ce travail est le résultat d'un projet de recherche qui vise à examiner le fonctionnement de la paternité impliquant le nom et l'oeuvre de Chico Buarque du point de vue de l'analyse du discours français, compte tenu de la relation entre le sujet, de la parole et de la paternité au point convergence avec l'histoire. Par conséquent, il a été pris comme corpus d'analyse, six lettres de la musique du compositeur, Chico Buarque, produite dans la période de la dictature militaire brésilienne, trois d'entre eux ont signé comme Chico Buarque et trois, signé par Julinho nom de Adelaide, pseudonyme auteur. Il était, par conséquent, pour le développement de la réflexion, le fait que le compositeur a créé une façon d'essayer de contourner la censure par un surnom qui a continué à signer des paroles écrites par lui. Ainsi, la recherche tient sous les contributions théoriques qui incluent les termes “sujet”, “discours” et “auteur” dans la perspective de l'analyse du discours, en particulier les contributions de Michel Foucault. Pour le développement de la proposition, il y avait une recherche de la littérature à travers le levage, la lecture et rapport de livre divers textes portant sur le sujet en question, suivie d'une analyse des lettres qui forment le corpus. De les lectures et les analyses ont abordé la question du fonctionnement de la censure dans le milieu de l'année 1960 et 1970, période de la dictature militaire brésilienne, pour la recherche que la question de la paternité peut être comprise dans cette période historique des postulats d'analyse discours et quels facteurs externes peuvent influencer la langue dans le fonctionnement de l'auteur, et qui valide un texte avec le nom que les signes. Par conséquent, il a été constaté que l'action de la censure sur des lettres écrites par Chico Buarque, a agi à partir du nom qui a été liée à la lettre et pas seulement le discours, ils ont attaché, la mise en place d'une forme de censure, ce est, malgré interférences fait, parfois, dans les textes, il y avait un examen préalable du contenu affiché à l'auteur de Chico Buarque.
O presente trabalho é resultado de uma proposta de investigação que tem como objetivo principal analisar o funcionamento da autoria envolvendo o nome e obra de Chico Buarque sob a perspectiva da Análise do Discurso de Linha Francesa, considerando as relações entre sujeito, discurso e autoria em ponto de convergência com a História. Para tanto, tomou-se como corpus para análise seis letras de músicas do compositor, Chico Buarque de Hollanda, produzidas no período da Ditadura Militar Brasileira, sendo três delas assinadas como Chico Buarque e outras três assinadas pelo nome Julinho da Adelaide, pseudônimo de autor. Considerou-se, portanto, para o desenvolvimento da reflexão, o fato de o compositor ter criado uma forma de tentar driblar a censura por meio de um pseudônimo que passou a assinar algumas letras de músicas por ele escritas. Desse modo, a pesquisa sustenta-se sob os aportes teóricos que contemplam os termos “sujeito”, “discurso” e “autoria”, na perspectiva da Análise do Discurso, em especial os aportes de Michel Foucault. Para desenvolvimento da proposta, realizou-se uma pesquisa bibliográfica, por meio de levantamento, leitura e fichamento de textos diversos, contemplando a temática em questão, seguida por uma parte de análise das letras que compuseram o corpus. A partir das leituras e análises, tomou-se a questão do funcionamento da censura em meados dos anos de 1960 e 1970, período da Ditadura Militar Brasileira, para investigação de como a questão da autoria pode ser compreendida nesse período histórico, a partir dos postulados da Análise do Discurso, e quais os fatores externos à língua podem influenciar no funcionamento do autor, bem como o que valida um texto pelo nome que o assina. Logo, verificou-se que a ação da censura, sobre as letras escritas por Chico Buarque, agiu a partir do nome que era vinculado à letra e não exatamente pelo discurso que elas,veiculavam configurando uma espécie de censura prévia, ou seja, apesar das interferências feitas, em alguns momentos, nos textos, havia uma consideração prévia do conteúdo veiculado à autoria de Chico Buarque.

Full textThe reserved share has two functions : a political function of organization of society and a social function of promoting a family model and a subsitance pattern. The political function’s purpose is to establish a political order by strengthening the political and economic objectives and ensuring the continuity of the city. Safeguarding property in the family, originally then dissipation of assets, today this function tends to disappear in favor of individual freedom of the deceased.The second function is a social function of promoting a family model and providing a subsitance pattern. The reserved share suits to our family model confining itself to the nuclear family. It also requires leaving a subistance after our death, to our forced heir. In positive law, the subsistence function takes the ascendancy on the promoting a family model fonction. The nature of the reserved share tends to resemble to a claim. In addition, the development of this fonction has led the legislator to amplify or to provide new competing rights to the reserved share

Full textDuring the last years, the use of circulating nucleic acids as diagnostic and/or prognostic tools in cancerology was widely documented. The recent development of non-invasive prenatal testing also reveals the growing interest of these biomarkers in obstetrics and gynecology. The circulating or extracellular nucleic acids have for particularity to be easily detectable in the biological fluids of the body and there are two types: (1) Cell-free DNA (cfDNA), short or long DNA fragments resulting from cellular apoptosis and/or necrosis (2) microRNAs (miRNAs), small non-coding RNA sequences, which regulate gene expression by interfering with their mRNA targets. Since it was demonstrated that cfDNA level is abnormally increased in some pathological conditions and miRNAs are involved in the regulation of several biological processes such as folliculogenesis and steroidogenesis, these two types of nucleic acids could constitute new biomarkers of interest in Assisted Reproductive Technology. In this thesis work, we quantified the cfDNA level and analysed the expression profiles of some miRNAs by quantitative PCR, in follicular fluid (FF) samples from women undergoing in vitro fertilization (IVF) procedure. We observed significant high cfDNA levels as well as specific miRNA expression profiles in FF from women with ovarian disorders (such as polycystic ovary syndrome or low ovarian reserve). Next, we investigated the potential of circulating nucleic acids as predictive biomarkers of IVF outcomes. We demonstrated that the intra-follicular cfDNA level and some miRNA expressions were significantly associated with in vitro embryo quality and the clinical pregnancy outcome. Therefore, the circulating nucleic acids offer new diagnostic and prognostic perspectives in human infertility management

Full textProperty reservation is a highly appreciated guarantee mechanism used for the sale of tangible assets. This mechanism is extremely effective in the case of bankruptcy as it combines all the advantages of a real security without its disadvantages. Considering the importance of intangible assets in today's society and given the fact that this importance will continue to grow as intellectual properties are at the heart of business transactions, the risk that the transferor of intellectual property may be faced with a defaulter must be underlined. This is why the transferor must plan sufficient payment guarantees. Although the property reservation clause is not yet automatic as is the case for tangible assets, contracts dealing with the transfer of intellectual property rights with this type of clause are becoming more and more frequent. The freedom of contracting ensures the validity of the principles of this clause ; however, one can wonder how pertinent this practice actually is. For intangible assets, is property reservation an appropriate mechanism and does it truly guarantee effective payment ? This study has lead to an affirmative response to these questions. Not only did this study show the absence of technical obstacles concerning such a guarantee, but it also found that this mechanism offers effective guarantee powers, as long as the notions of claim and restitution of tangible elements are clarified

Full textThe brain reserve capacities represent the resilience of the brain to cope against different pathological processes such as Alzheimer's disease (AD). Several hypotheses have been proposed to explain this mechanism. The two most validated concepts are the brain reserve referring to brain volume and cognitive reserve referring to brain function. Epidemiological and imaging data helped identify life experiences associated with better brain reserve capacities. Thus, the education, occupation and practice of leisure activities are recognized as proxies of the brain reserve capacities. The main objective of this thesis aimed to better characterize the relationship between these proxies and the brain reserve capacities. First, from brain imaging data collected during follow-up of the three cities cohort of Bordeaux, we examined the relationship between life experiences and brain volume. Only the education was associated with differences in gray and white matter volume. In addition, highly educated subjects had a smaller progression of white matter hyperintensities during the follow-up of this cohort independently of the presence of cardiovascular risk factors. Education seems to have a significant role in the formation of brain reserve capacities in both cognitive reserve and brain reserve. This explains the protective role of educational level against dementia. In a third work, we used this particular relationship between educational level and dementia to illustrate how a social factor can be a factor of a chronic disease related to aging and can modify the occurrence of this disease. Finally, we are interested in the relationship between the practice of leisure activities during retirement and the risk of dementia from data of Paquid study. The practice of playing board games is associated with a lower risk of dementia, but the strong link with cognition not eliminates reverse causality. However, a greater engagement in the practice of leisure activities in retirement is associated with a lower risk of dementia similar to subjects who always practiced activities. Intervention trials could confirm the beneficial effect of the practice of leisure activities on cognition and dementia risk

Full textOpposable to the bankruptcy of the vendee since the law on the 12 th may 1980, the simple property reserve clauses stipulated by the vendors of tangible personal estate can influence the conditions of concession for a banking credit for the industrial and commercial firms. In the monist structure of french law sale contract, by suspending the vendor's main obligation of giving, the property reserve clause suspends in consequence his other obligations, of delivery and guarantee; it impedes the usual way of sale and incites the vendee - especially if he may profit by a prompt payment discount - to pay cash by having recourse to a credit-system for the vendee. The bank financing their clients' purchases instead of their sales, by treasury credit, or "dailly", will see, in spite of the personalized charac- teristic of the granted credit, their financial risk dull. The property reserve clause benefit, useless to the cash-paid vendor, can - as the credit-lessor property right - guarantee it efficaciously, because the special movable secu- rities traditional exercice is today compromised in right and in fact while on the contrary the reserved property right titular disposes as for him of an absolute "preference right". The reserved property right, accessory real right of the guaranteed debt, appears, on account of the synallagmatic character of the payment convention, as a necessary accessory of the debt right, the transfer of which to the bank will enter in the contract cession scheme

Full textThe Retention of Title mechanism, recognized by the law as a security over assets since the Order of 23 March 2006, uses the property right for guarantee purposes. Actually, the retention of title suspends the transfer of property or good(s) until full payment of the price by the debtor. This legal technique affords an effective protection to the creditor who is faced with the initiation of collective insolvency proceedings against his contractual partner. This technique allows the creditor to be considered by the legal entities involved in the proceedings not only as the holder of a security right but also as the owner of the good. Thanks to this double-hatting approach, the position of the creditor is enviable compared with others creditors because providing, in particular, the opportunity to proceed to an action in restitution. However, this privileged position can otherwise conflict with the recovering of the company in difficulty and the principle of equality of creditors. The aim of this thesis is in the light of the legal and jurisprudential evolutions, to discuss the nature of this security interest and to challenge its effectiveness as regard from the one of the collective insolvency proceedings of the buyer

Full textThis dissertation focuses on one of the more singular modes of reception in Brian Evenson’s body of work: reticence. While reading Brian Evenson’s works, the reader is made aware of gaps, that seem to point to the existence of a missing part of the text, hollowed out from the narrative before it has even started. The reader then experiences a form of deficiency that he identifies in the text as coming from what is missing. As he tries to reconstruct the text and to make it whole once again, as illusory as that concept might be, the reader attemps to fills the gaps through the workings of his imagination. He then produces interpretations, but those rest on constructed worlds that see their rare landmarks being gradually erased. His reading experience is imbued with uncertainty, mainly because the worlds the stories are set in are unstable and populated with linguistic anomalies. Moreover, his interpretations generate more uncertainty, thus thwarting his attempts to resolve the ambiguities of the text permanently. However, while stumbling on the elusive meaning and the prevailing ambivalence, he discovers that the proliferation of his interpretations brings forth that of the narrative and linguistic proliferation at the root of the many ambiguities of the text. Thus, the failed attempts of the reader to fill the gaps in the text give way to a second reading experience, during which he must ensure that all the potential intepretations are summoned in the text. With the help of his imagination, the reader thus produces a form of textual excess that must substitute itself to the one that he can barely sense in the white spaces of the text. The proliferation of language and the perpetual surging of meaning that this new excess allows insure a reading experience of proliferation superimposed on top of the initial experience of loss

Full textAccording to french law, property is transferred to the buyer as soon as the acceptance meets the offer unless the parties agree on a later time, such as the payment of the price. In the sale of goods, retention of title until full payment may thus provide a security to the seller who stays the legal owner as long as total price has not been paid. This works intends to study the effects of the retention of title clause in the sale of goods and to figure out how reliable is the seller's security of payment the clause offers whether the purchaser goes or does not go bankrupt

Full textImmediately after the publication of phenomenologie de la perception, merleau-ponty's thought was regarded as a "philosophy of ambiguity" (alquie, 1947), and he himself was sometimes considered as an "ambiguous philosophers". It was a major mistake. The theme of ambiguity pervades his first works, gradually losing ground in the last ones though never disappearing completely in the face of more positive themes such as those of the flesh, chiasm, or interlacing. Ambiguity, indeed, runs prominently through the whole of merleau-ponty's philosophical project and it silently shapes his analyses of perception, body, or language, as well as his readings of descartes, husserls, or even bergson. The necessity and position of ambiguity can only be apprehended in the ultimate attempt at thinking the theme of the flesh. Against the urge of knowing, which eludes our primeval relation to the world, by only opening to the subject the field of an unending rivalry with the object, we are invited to adknowledge that the primeval sensible, in its origins, is neither tomb, nor source, of the mind, but the place and motive for its opening and blooming out. And this, because from the beginnings "we are of it", and because our intimate being prepares itself in the thick of the primeval flesh, an unnamed reserve of being, in which nothing can be discerned, before, both in their self-opening and dehiscence, each being, dares at last exist. It is

Full textChemotherapy induces infertility by exerting a direct toxicity on the ovaries, resulting in a depletion of the follicular stockpile. Cyclophosphamide (Cy), widely used for breast cancer, is recognized as one of the most gonadotoxic agent. Recently, it has been proposed that Cy gives rise to follicular depletion by a massive growth of resting follicles which are then destroyed. Since Anti-Müllerian Hormone (AMH) is one of the factors regulating primordial follicles activation, we hypothesized that this hormone might limited Cy-induced gonadotoxicity. We have shown in pubertal mice that recombinant AMH injections are able to preserve primordial follicle loss Cy-induced and might improve fertility outcome after treatment. In addition, we provide evidence that autophagy could be one of the mechanisms involved in the inhibition of follicular recruitment by AMH. At least, nowadays, the “gold standard” method of evaluating ovarian reserve in mouse is a process particularly time-consuming and tedious. We developed a new methodology of automatic primordial follicles detection and counting within mouse ovaries, using modern artificial intelligence methods, especially deep learning approach

Full textThe thesis rests on the approach and the creation of Associations in military matter. It shows initially th emergence of patriotism native of the Moselle region during the first annexation between 1871 and 1918, the intensive engagement of the executives of reserve at the time of difficulties of the military compagny of inter-war period and the installation of the legal and military statutes ; the unit being included in a contexte of successive crises and reorganization of the army of active after events of algeria where Associations will acquire and sit their power. In this particular context, one discovers the importance of associations of Or and SOR, their legal character where the French law of 1901 is not applicable in the Moselle. It is this essential to show that recruitment, the activities, the importance of the national congresses, but also the expansion of the industrial criteria at the beginning of the years 1950 do nothing but amplify the ascending phenomenon. Then, in an associative world arrived at the paroxysm of its power at the beginning of the years 1980, to explain that from now on the assets of the members seem illusory and do not answer reality any more. Lastly, to admit that with the suspension of the conscription, Associations start a long crossing of the desert and that they sink gradually in anonymity, dining on time when the xtreme upheavals come as much from the army from active as of the reserve

This thesis will re-examine La ricotta, through a theological prism : using the Eschatological Reservations developed by Johann Baptist Metz in tandem with the Liberation Theologists. In the light of this concept, the study of the trial of La ricotta and its central tension built around the comic, the sacred and the blasphemous, will allow us to consider the political weight of Pasolini’s aesthetic choices and to reconstruct the historic background of his work. La ricotta was commissioned as a film about the end of the world. One may shed new light on Pasolini’s creation by using eschatological theory. Through his interpretation of the Passion of Christ, he appears as a Marxist atheist within his asserted and revitalized Christian culture. To conclude, the Eschatological Reservations influence Pasolini’s aesthetic interpretation of the poor and their voices in Laricotta, and herald a new era, the Age of the Extras

Full textAt a time when the modern family is conceived in the plural, at a time when ascendants organize upstream transmission and devolution of their heritage, at a time when globalization advocates the standardization of law and the end of specificities States, it is necessary to question the future of the hereditary reserve. Parents no longer wish to be deprived of their power to freely dispose of their patrimony, even for reasons of death. What to answer to a father who is anxious about seeing his heritage squandered by an ungrateful child with whom he lives only conflicts ? What to say to this child who saw his brother favored by maternal decision, in an abusive and arbitrary way ? What advice can be given to those individuals who open the door of our offices every day to ask the help of their notary ? What to say to this husband who wants to protect his spouse from the angry of children from a first bed ? In order to answer them in practice, let us study ways of circumventing this hereditary reserve. Let's focus on checking their effectiveness. Beyond the classical mechanisms of the Civil Code such as the will and the gift, the interest of this thesis is to turn to more complex mechanisms, in order to answer the parents disappointed by their offspring, but also to them, children wronged to give them legal means to counter unfair deprivation. It is useful to understand and know what can be done to transmit one's heritage with a recovered freedom without risking the wrath of the law. Through the study of these instruments, their efficiency and their legal and family treatment, the question of the modernization of the reserve resurfaces. The family changes, and with it, the traditional conception of the hereditary reserve

Full textThis thesis is about the identification of the ways used and supported by the various generations of Pekuakamiulnuatsh women and men to transmit their knowledge to the other generations. It is pointed out that the roles assigned to the transmission of the knowledge vary according to the age of the person who transmits and the one who receives. The roles also vary according to the sphere in which this transmission is made. Indeed, the private sphere privileges the oral tradition, i.e. in the family, while the writing processus is strongly used in the public sphere, as in the school. The dynamic use of the Western and Indigenous ways of transmission is necessary to counterbalance the knowledge and their practices in this very heterogeneous community. It also reinforces the ilnue identity and gathers the community towards the same political and cultural projects.

Full textDuring the past quarter century Michel Foucault's theories have gained admittance to the domain of French social sciences, most notably that of sociology, though not without difficulty. Whereas previously sociologists remained indifferent or, in some cases, looked down on Foucault's work, his theories are now being acknowledged as relevant - gaining a new status as objects of interest. Within a contemporary framework, the reception and spread of Foucault's theories demonstrates a pointed evolution. In order to effectively analyse the modes in which this borrowing occurs, the transference and transformation of three particular notions within the framework of contemporary French sociology will be closely examined: "rationalisation", "normalisation" and "body", notions which were continuously re-visited and elaborated upon by Foucault, particularly within his critical analysis of social formations

Full textThe Archaeplastida appear approximately 1.6 billion years ago when a heterotrophic eukaryote cell established a symbiotic relationship with two partners: a cyanobacterium and a chlamydiales. During the endosymbiosis process, the cyanobacterium has evolved to plastid, while chlamydiales have left in Archaeplastida a fingerprint of 50 genes. In parallel Archaeplastida have substituted the glycogen biosynthesis by starch. If the role of ancestral cyanobacteria is pretty obvious in the emergence of Archaeplastida, what about those parasitic bacteria? One effectors secreted by the chlamydiales corresponds to glycogen synthase activity (GlgA). Phylogenetic analyses point out that starch synthase III/IV isoforms have probably evolved from GlgA of chlamydiales. We hypothesize that GlgA activity of chlamydiales displays unique biochemical properties that could explain why this activity has been selected in the Archaeplastida. In this manuscript, we, first, report the characterization of mutant strain of cyanobacterium strain, which produce only glycogen. This phenotype is correlated with a defect in the GlgA2 isoform, which belongs to the same family of SSIII/IV of plants. Altogether, results suggest that GlgA2 is indispensable to starch in the Cyanobacterium sp. CLg1. We also carry out the biochemical characterization of synthase activities of the chlamydiales. We show that GlgA activities of some chlamydiales are able to use both nucleotide-sugars: ADP-glucose and UDP-glucose. These results stress out that GlgA activities of some chlamydial species have evolved to be more efficient to hijack the carbohydrate storage of infected cell

Full textNos résultats ont montré que les facteurs structurants de la végétation varient suivant la géomorphologie et surtout le dispositif de zonage (gradient anthropique). C’est dans les milieux perturbés que la diversité est élevée, mais avec un niveau d’organisation peu homogène comparativement aux milieux non perturbés. L’intensification actuelle des pressions dans les milieux perturbés et la dégradation des formations végétales qui en résulte n’entraînent pas actuellement dans la réserve une baisse de diversité. Aussi, dans les conditions écologiques locales pratiquement semblables dans la réserve, le zonage caractérisant les niveaux d’anthropisation est autant important que les facteurs texture du sol qui sont liés aux conditions géomorphologiques dans la structuration floristique. Les résultats phytosociologiques ont montré l’individualisation de 10 groupements végétaux dont 6 en milieux perturbés avec une tendance à la dégradation de la végétation et sa transformation en savane arbustive et 4 en milieux non perturbés marqués par la disparition des formes de végétation originelles. La plus forte densité en espèces est observée dans les groupements végétaux des unités de plaine et de vallée pour l’ensemble des 3 zones. C’est dans ces unités également que la surface terrière pour les arbres de plus de 8 m et la valeur pastorale sont importantes. La diminution du recouvrement des espèces herbacées de bonne valeur fourragère en particulier les pérennes est corrélée aux perturbations liées aux intenses activités anthropiques (agricole et pastorale par exemple). Ces activités engendrent la dégradation du milieu, une baisse de la valeur pastorale qui est indépendante de la biodiversité. Les dynamiques temporelles de la composition du paysage forestier de la réserve ont montré une ouverture du paysage caractérisée par une extension des superficies cultivables de la zone de transition vers la zone protégée ainsi que la réduction de la superficie des savanes arborées et la transformation progressive du paysage en savane arbustive. L’étude a permis de comprendre que le dispositif législatif classique de protection ne correspond pas à la réalité de terrain. De façon générale, l’influence des gradients géomorphologique et surtout anthropique est perceptible sur la structure de la flore et de sa diversité.
Une extension de notre approche d’étude dans les réserves de Badinko et de Kongosambougou permettra d’asseoir un dispositif de suivi de l’évolution spatio-temporelle de la végétation et de poser les bases d’une politique rationnelle de conservation de la réserve de biosphère de la boucle du Baoulé.

ABSTRACT
The research was conducted in the Fina, part of biosphere reserve of « boucle du Baoulé » (RBBB) in Mali. This reserve consists of 3 areas, Badinko, Kongosambougou and Fina. Fina area is the most important for its rich fauna, this study was done. The climatic conditions pejoration and the impacts of increasing human pressures have led to ecosystem degradation, particularly plant biodiversity of the Fina reserve. In this study we have updated data on plant diversity and its variation based on the device of biosphere reserve zoning based on the pressure degree (protects systems). The objective of this thesis was to test the main hypothesis that protected areas are witness spaces of natural settings conservation that, compared to the disturbed areas, would characterize plant biodiversity evolution. Two approaches were used to address this study: synchronic and diachronic approach. Our results showed that the vegetation structural factors vary with the environment (zones) and geomorphology. The correlations between vegetation and ecological factors showed that the disturbance gradient is a major factor in the floristic variability. Human pressure intensification in disturbed habitats and resulting vegetation degradation do not currently induce any decrease of diversity in the reserve. In local similar environmental conditions as is the Fina reserve case, zoning characterizing the human impact levels is as important as the soil texture factors that are related to geomorphological conditions in the floristic structure. The phytosociological results showed the individualization of 10 plant groups in disturbed habitats, including 6 with a tendency to shrubby savanna and 4 in undisturbed environments marked by the disappearance of the vegetation original forms. The highest density of species is observed in plant communities of the plain and valley units in all the three zones. It is also in these units that basal area for trees over 8 m and pastoral value are important. The herbaceous species of good fodder value recovery reduction in particular the perennial causes the environmental degradation, and the pastoral value reduction that is independent of biodiversity. Temporal dynamics of the forest landscape composition of the reserve showed an opening of the landscape characterized by an expansion of arable land in the transition zone to the protected area of the reserve, the decrease in savanna area and gradual transformation landscape in shrubby savanna.
An extension of our study approach in the Badinko and Kongosambougou reserves could help establishing a monitoring of the spatial and temporal vegetation evolution and putting the rational politics bases of Baoulé biosphere reserve conservation.

Full textThis research presents the evolution of the literacy of 11 kindergarten children at Wahta’ school, an elementary school located in the community of Wendake, in Québec. Two data collections were carried out: one at the beginning of the school year and the other at the end of the 2018-2019 school year. These data collections made it possible to determine the children's reading and writing skills. In order to assess their progress, three foundations were analyzed: the narration, the syntax and the representation of the alphabetical system. The results show that the majority of children make progress in structuring the narrative, but few achieve the level of causality necessary at the start of formal learning to read. In terms of syntax, qualitative analyzes show little progress, as children from the start of the year are generally already advanced. As for the representation of the alphabetical system, more than half of the children did not progress at the code level. At the end of kindergarten, only five children out of eleven show sufficient progress to the beginnings of decoding. This study highlights the importance of monitoring the literacy development of First Nations children and of fostering the emergence of literacy by anchoring it in interventions involving culture and child's literature of First Nations.

Full textClimate, soils and water resources are essential factors of agricultural production and affect the availability of world food resources. The need to quantify, assess and predict pressures on water resources and agricultural resources in the context of climate change is a major issue. To answer these questions, numerical models of the processes at stake over continental surfaces are developed. They simulate many natural processes such as the water cycle, the carbon cycle, vegetation growth and senescence, and the fluxes at the soil-atmosphere interface. These powerful tools are widely used by the scientific community but present many uncertainties in the representation of the various biophysical processes taken into account and in the estimation of the parameters that drive them. The lack of observation data for key hydrological cycle variables or key vegetation variables of large spatial and temporal scales is a major obstacle to the validation of these models. The general objective of this thesis is to evaluate how the integration of satellite data available over the last thirty years in a generic model of continental surfaces allows a better representation of agricultural droughts at different spatial scales. The ISBA-A-gs model developed by CNRM is used. It represents the interannual variability of plant biomass in relation to soil water resources. Previous studies have shown that simulations of the soil-plant system under water stress conditions are very sensitive to the value of the soil maximum available water content, and that the representation by this type of model of the interannual variability of cereal straw is difficult. A model calibration / validation methodology based on the integration of Leaf Area Index (LAI) satellite time series observed at 1 km resolution in ISBA-A-gs was developed. The objective is to estimate the soil maximum available water content for non-irrigated straw cereal crops. The satellite LAI is first disaggregated for straw cereals. The validation of this methodology is based on a comparison of the simulated above-ground biomass with observed agricultural yields. A simple method of inverse modeling by minimizing a cost function is compared with a more complex method: sequential data assimilation. The latter allows optimal combinations of the LAI time series observed and simulated by ISBA-A-gs to provide an analysis of LAI, above-ground biomass, and soil moisture. The assimilation is based on the LDAS-Monde chain developed by CNRM. It gives more realistic results than inverse modeling in terms of simulated biomass and of soil maximum available water content. The representation of the negative impact of droughts and very wet years on yields is improved by this method. It is found that the soil maximum available water content retrieved on the French cereal areas correlates with the maximum annual values ??of satellite LAI (LAImax). A simple linear regression model can be used to estimate the soil maximum available water content directly from LAImax . The mapping of the soil maximum available water content as derived from LAImax is compared with the one millionth map of INRA over France. The possibility of using this method at a local scale is evaluated, as well as its extension to other agricultural areas in Eurasia and North America

Full text" T. Hydrothermalis " produces a polysaccharide during the log phase, which is similar to glycogen, and hydrolyzes it quickly during the stationnary one. The elongation activity (42 kDa) is optimal at 80ʿC/pH 5,5 and is able to use ADP-glucose and UDP-glucose with the same affinity, but the Vmax is 10 fold better with ADP-glucose suggesting that is might be the physiological substrate. The branching activity appeared unstable, then avoiding further enzymatic studies. Moreover, an original structure with long chains and branched at 7,5 % was purified from the archaeon at the end of the log phase. At the beginning of the stationnary phase, hydrolases are able to degrade quickly this kind of polymer and more slowly these similar to glycogen. The structural change then appears as a way, for these degradative enzymes, to get an easier access to the glucose stores, and to allow an optimal ATP production, and it may involve the glycogen-synthase and a glucanotransferase activity

Full textThrough the reconstruction of a memorial space, the Biblical Landscape Reserve of Neot Kedumim articulates plants and landscapes in order to link them to the cultural and social jewish values. The initial project of creation of the Reserve, modeled on the sionist ideals and the national context of the creation of the State of lsrael, was finally induced to develop these last years, towards a public issued from diaspora and lacking identity investment, a touristic and memory calling combining planting activities and experimenting a natural scene as a product from history and traditional texts. This crossing of the representations of nature in the jewish culture is followed by a deciphering of the social uses of hiking on thematic trails and of recurrent textual practices associated with, at last of the specific use of commemoration as a relevant tool for reappropriation of memory and territory
