Ph. D.
Tendons are fibrous, elastic bands of collagen that connect muscles to bones and are essential to movement and proper functioning of the skeletal system. Weight-bearing tendons like the Achilles in humans and superficial digital flexor tendons in horses are particularly prone to damage and degeneration with overuse and/or aging. Bone marrow-derived stem cell treatments have shown promise in the reduction of pain and inflammation, and restoration of native tendon structure and function in cases of severe tendon injuries. However, the roles of stem cells in tendon healing, particularly their ability to transition to cell types native to tendon and integrate with an environment distinct from their own is unknown. Culturing of stem cells in three dimensional (3D) environments has enabled us to identify and understand the biochemical and mechanical signals that trigger stem cell transitions to tendon cells in tendons, but currently available 3D culture systems are complex and inefficient. In this dissertation we have developed a cost-effective and high throughput 3D culture system to assay the potential of stem cells to form tendon cells and composite tendon-like tissues. Toward this, we have also optimized the effects of known tendon proteins on the tendon fate in 3D culture of stem cells. Like most adult tissues, the tendon encompasses an in-house repository of stem cells. Tendon stem cells (TSCs) are primarily responsible for the inflammatory and reparative responses to tendon injury. Recent evidence suggests that TSCs are diverse in character, and differ from each other in their ability to form cells and tissues of fat, bone and cartilage. In this work, we provide evidence that TSCs are also differently committed to forming tendon tissue, and moreover that significant inter-relationships among gene expression patterns in these cells directly contribute to cultural diversity. In sum, our results provide novel insight to the roles of stem cells in tendon healing, particularly their response to subtle changes in their biochemical environment, and the contributions of individual cells in a milieu to a holistic reparative response.
Theriault, Francesca M. "Regulation of neuronal diversity in the mammalian nervous system." Thesis, McGill University, 2007. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=103300.
Another significant step in the development of the mammalian nervous system is the acquisition of distinctive neuronal traits. This thesis also shows that Runx1 is expressed in selected populations of postmitotic neurons of the murine embryonic central and peripheral nervous systems. In embryos lacking Runx1 activity, hindbrain branchiovisceral motor neuron precursors of the cholinergie lineage are correctly specified but then fail to enter successive stages of differentiation and undergo increased cell death resulting in neuronal loss in the mantle layer. Runx1 inactivation also leads to a loss of selected sensory neurons in trigeminal and vestibulocochlear ganglia. These findings uncover previously unrecognized roles for Runx1 in the regulation of neuronal subtype specification.
This thesis thus presents a novel factor which functions at several steps in the development of the mammalian nervous system and adds to the growing body of work on the processes involved in elaborating such a complex and vital structure.

Islam is the fastest-growing religion in Europe, primarily due to immigration and higher fertility rates among Muslims. For most European countries, in terms of socio-economic and demographic calculations, the need for an influx of immigrants was due to the trends of aging nations and the needs of the European labor market. Migration processes are becoming an important factor in socio-religious transformation in Europe and require finding ways to integrate Muslim communities into European societies, one of the goals of which is to preserve the national identity of European countries. The purpose of the scientific work is to identify and substantiate the impact of Islamic factor in the European cultural-civilization space. The civilization is a system whose constituent elements are peoples, nations, states, integrated into a certain integrity, the system-forming factor of which is the value-world unity, accumulated primarily in religious experience and spiritual practice. Of course, different civilizations have common features of an objective nature, such as language, history, religion, customs, institutions.
Іслам є найбільш швидкозростаючою релігією в Європі, в першу чергу завдяки імміграції та підвищенню рівня народжуваності серед мусульман. Для більшості європейських країн, з точки зору соціально-економічних та демографічних розрахунків, необхідність припливу іммігрантів зумовлена тенденціями старіння націй та потребами європейського ринку праці. Міграційні процеси стають важливим фактором соціально-релігійної трансформації в Європі і вимагають пошуку шляхів інтеграції мусульманських спільнот до європейських суспільств, однією з цілей яких є збереження національної ідентичності європейських країн. Метою наукової роботи є виявлення та обґрунтування впливу ісламського чинника на європейський культурно-цивілізаційний простір. Цивілізація - це система, складовими елементами якої є народи, нації, держави, інтегровані в певну цілісність, системоутворюючим фактором якої є цілісність-світова єдність, накопичена насамперед у релігійному досвіді та духовній практиці. Звичайно, різні цивілізації мають спільні риси об’єктивного характеру, такі як мова, історія, релігія, звичаї, установи.

Desde 1996 que as empresas portuguesas têm vindo a escolher o Brasil como mercado de eleição para a localização dos seus investimentos. Este país passou a ser um factor crucial na definição das estratégias de internacionalização das empresas portuguesas. As teorias que argumentam que o processo de internacionalização é um processo de decisões incrementais no sentido de um envolvimento crescente das empresas em operações internacionais, sugerem que quando a experiência das empresas acerca do desenvolvimento destas operações é reduzida, estas optarão de início por investir em países psicologicamente/culturalmente mais próximos do país de origem. O presente trabalho parte do pressuposto de que a proximidade cultural entre Portugal e o Brasil foi um factor influente no processo de decisão conducente ao investimento das empresas portuguesas neste país. São estudados cinco casos de empresas portuguesas que investiram no Brasil, no sentido de confirmar ou não este pressuposto. As questões relacionadas com a gestão dos recursos humanos e o recurso das empresas aos gestores expatriados, são igualmente analisadas por se entender que é a este nível que a gestão da diversidade cultural coloca mais problemas.
Since 1996 portuguese companies have chosen Brazil as a preference market for the location of its investments. This country thus became a crucial element in the definition of the internationalization strategies in the portuguese companies. The theories that consider the internationalization as an incremental process, in which the companies will become gradually more involved in international operations, argue that these companies, because of their scarce experience about these operations will choose, in an initial stage, to locate its investments in psychology/culturally countries close to their home market. This work starts with the argument that cultural proximity between Portugal and Brazil was an influent factor in the decision process that has lead the companies to invest in Brazil. Five cases of portuguese companies that have invested in Brazil, are studied, with the goal of confirming, or not, this argument. Issues concerning human resource management, as well the use of international managers as a resource are also analysed, because of the assumption that it is on this level that management of cultural diversity faces more problems.

Ribeiro, Sébastien. "Rôle de la cassiicoline dans l'interaction compatible Hevea brasiliensis / Corynespora cassiicola : vers la sélection assistée par effecteur : Biologie végétale." Thesis, Université Clermont Auvergne (2017-2020), 2019. http://www.theses.fr/2019CLFAC010/document.
The rubber tree (Hevea brasiliensis) is the primary commercial source of natural rubber worldwide. In Asia and Africa, H. brasiliensis is affected by the Corynespora leaf fall (CLF) disease, caused by the broad-spectrum necrotrophic fungus Corynespora cassiicola. During severe attacks, massive fall of young leaves can occur in susceptible cultivars. Early evaluation of the susceptibility of rubber clones in breeding programs is required to avoid developing highly susceptible clones that would amplify the disease. An indirect phenotyping procedure envisaged consists in testing the sensitivity to the fungal toxins (or effectors) rather than the susceptibility to the fungus itself (toxin test). Among all putative effectors identified in silico, only cassiicolin Cas1 has been purified and characterized to date. This small secreted glycoprotein was for long suspected to play a role in the early phase of infection by inducing tissue necrosis. Strains carrying the Cas1 gene are the most aggressive on tested rubber clones. However, strains without cassiicolin gene (called Cas0) still show moderate aggressiveness, suggesting the existence of effectors other than cassiicolin. The objectives of this study are (i) to determine if susceptibility to cassiicolin Cas1 is a relevant selection criterion to eliminate the rubber clones most susceptible to CLF disease, and (ii) identify molecular factors involved in the sensitivity to Cas1, in rubber tree. We have thus analyzed the typology of a large set of C. cassiicola isolates collected from various rubber plantations in West Africa. Our results show that isolates carrying the cassiicolin isoform Cas1 are widely represented, but that the most represented type (A/Cas0) are isolates without cassiicolin gene. Here we show that deletion of the cassiicolin gene in the isolate CCP resulted in a total loss of virulence. This clearly demonstrated that cassiicolin is indeed a necrotrophic effector required for the virulence of isolate CCP in rubber tree. Finally, we have investigated susceptibility factors to cassiicolin Cas1 on rubber tree with two different approaches. We identified about thirty candidate proteins that could physically interact with the toxin, through the two-hybrid assay. A transcriptomic approach allowed us to identify the rubber genes differentially expressed in response to the purified cassiicolin, comparing a susceptible clone (PB260) and a tolerant clone (RRIM600). In conclusion, we think that the necrotrophic effector Cas1 can be an interesting tool for effector-based selection of tolerant clones for African plantations; however, efforts should also be placed on A/Cas0 isolates, in order to identify potential necrotrophic effector(s) responsible for their virulence. This would enlarge the potential of effector-based selection

"Étude des distorsions du répertoire immunitaire en tant que facteur pronostique de risque chez les patientes souffrant d’un cancer du sein métastatique en 1ère rechute : étude de la valeur pronostique de la lymphopénie et de la divpénie." Thesis, Lyon 1, 2012. http://www.theses.fr/2012LYO10029.
Previous work of the team demonstrated the major impact of lymphopenia (<1Giga/L), detected before treatment, on overall survival of patients with solid metastatic cancer, highlighting the importance of immune system in controlling tumor progression. During my thesis project, I analyzed the contribution of the combinatorial diversity of the TCR β chain, another indicator of the quality of the immune system, as a prognostic marker in patients with metastatic breast cancer. I was able to show that a score combining the diversity of TCR and the number of lymphocytes (score NDL) is an independent factor of poor prognostic in multivariate analysis. This score allows identification of a subpopulation of patients at risk who has both a lymphopenia and a low combinatorial diversity (<33%) of TCR and for which a reduction in the median survival was observed. We also made further study of the impact of subpopulations of lymphocytes and plasma cytokines. In parallel, I developed molecular tests to improve the study of TCR repertoire diversity at the genomic level. This work opens the door to new therapeutic strategies that would consider immune system dysfunctions. Indeed, following these results, a clinical trial based on the administration of IL-7 cytokine for the expansion of T cells before or during chemotherapy has been activated at the Centre Léon Bérard
Oliveira, Maria Luiza Guimarães de. "Sequenciamento de nova geração do gene IRF4: identificação de variações associadas a fenótipos de pigmentação na população brasileira." Universidade de São Paulo, 2016. http://www.teses.usp.br/teses/disponiveis/17/17135/tde-05012017-120156/.
The Interferon Regulatory Factor 4 (IRF4) gene, located at chromosomal region 6p25- p23, is a member of the interferon regulatory factor (IRF) family, a group of DNAbinding transcription factors, with the IRF4 primarily associated with immune system development and response and expressed exclusively in immune system cells and melanocytic lineages. Although many studies have shown that IRF4 is associated with many human conditions, such as melanoma and chronic lymphocytic leukemia, a recent Genome-Wide Association Study (GWAS) identified that alleles from the SNP rs12203592 (intron 4) is also associated with phenotypic variation regarding presence of freckles, hair, eye and skin pigmentation. Functional studies in human and mice melanin-containing cells revealed that such SNP is directly involved in the regulation of IRF4 expression, suggesting a clear role in melanocyte pigmentation. In spite of these findings, the regulatory and coding IRF4 diversities in admixed populations have not been evaluated so far. In order to verify if other variation sites spread across the IRF4 gene may be associated with human pigmentation, the regulatory (promoter and 3\'UTR regions) and coding (9 exons and flanking intronic regions, including the SNP rs12203592) regions were analyzed by next-generation sequencing procedures in a Brazilian admixed population sample. The population sample was composed of 228 unrelated individuals from the Ribeirão Preto area, São Paulo State, Brazil, which were stratified according to eye (blue, green, hazel, light-brown, and dark-brown), hair (red, blond, dark-blond, light-brown, dark-brown and black) and skin (light, intermediate and dark) pigmentation, as well as regarding the presence of freckles and intensity of hair greying. DNA libraries were prepared using the Haloplex Target Enrichment System (Agilent Technologies) and sequenced at the MiSeq platform (Illumina). CutAdapt, BWA and GATK software packages were used for trimming adaptor sequences, alignment and genotype calling, respectively. Missing alleles and haplotypes were inferred by using the PHASE method, although the known phase between variable sites (obtained by GATK) was taken into account. A total of 105 variation sites were identified. Only two of them presented genotype frequencies that did not fit Hardy- Weinberg equilibrium (HWE) expectations. Eighteen of these SNPs presented strong association with at least one pigmentation feature. However, if the conservative Bonferroni correction for multiple tests is taken into account, only two associations, both of them involving the rs12203592 SNP, remain significant: allele T associated with light skin and blue eyes. This result is in agreement with previous reports that the rs12203592*T allele leads to reduced IRF4 activation and reduced tyrosinase expression, leading to sun sensitivity and blue eyes. A total of 101 different haplotypes were inferred, and haplotype distribution was in agreement to HWE expectations. When haplotypes were subdivided in promoter, coding and 3\'UTR haplotypes, 17, 29 and 37 different haplotypes were observed, respectively. Various associations were identified, particularly involving the most frequent promoter haplotype, the two most frequent coding (only one of them with allele rs12203592*T), and the most frequent 3\'UTR, all of them with light skin, blue eyes, brown hair and hair greying. These results suggest that other variation sites besides rs12203592, when considered in a haplotypic background, are associated with human pigmentation.

Los cefalópodos constituyen un grupo faunístico importante en los ecosistemas marinos, representando elementos clave en la estructura y dinámica de las redes tróficas. Además, son un importante recurso pesquero y su contribución a los desembarcos pesqueros mundiales se ha incrementado significativamente en las últimas décadas. En el Mar Mediterráneo existen varios estudios locales sobre la abundancia y distribución de cefalópodos, pero pocos integran escalas temporales largas y áreas extensas. Esta tesis combina estudios sobre la estructura de la comunidad, la diversidad y la abundancia de cefalópodos a gran escala espacio-temporal (Parte I) con estudios a escala local alrededor de las Islas Baleares (Parte II). En primer lugar, se realizó un análisis de la comunidad de cefalópodos a escala de todo el Mediterráneo para describir el estado actual y determinar posibles diferencias entre las sub-cuencas occidental y oriental (Capítulo 2). El objetivo fue comparar la estructura de las comunidades faunísticas entre estas dos sub-cuencas y analizar la influencia de gradientes ambientales a gran escala sobre la composición específica. Aunque no se observaron diferencias significativas en la composición específica, las contribuciones relativas de las diferentes especies variaron entre ambas cuencas. Debido a su corto ciclo vital y estrategia reproductiva semélpara, los cefalópodos son muy sensibles a los cambios ambientales, adaptándose a ellos con relativa rapidez. Se esperaba, por tanto, que factores ambientales como la temperatura superficial del mar (SST) y el contenido de clorofila a (Chl a) fueran factores importantes en la estructuración de las comunidades de cefalópodos. Si bien su importancia difirió entre las dos sub-cuencas, se confirmó que la profundidad era el factor estructural más importante en dichas comunidades. Se analizaron también cambios en la diversidad específica de las comunidades de cefalópodos a escala de todo el Mediterráneo durante los últimos 20 años (Capítulo 3). Los resultados no mostraron ninguna tendencia temporal ni espacial (latitud, longitud) clara y homogénea en la diversidad. Las únicas tendencias temporales observadas variaron entre diferentes sub-regiones, siendo la posición geográfica, profundidad, SST y productividad los principales factores determinantes de estas tendencias. Para confirmar la importancia de la variabilidad ambiental a nivel específico, se analizó la influencia de la SST y la producción primaria en la estructura espacial y la dinámica poblacional de dos especies de cefalópodos de importancia comercial (Capítulo 4). Aunque Octopus vulgaris e Illex coindetii exhiben diferentes estrategias vitales y viven en diferentes hábitats, las tendencias temporales a largo plazo en su abundancia y el comportamiento sincrónico de sus poblaciones fueron similares, observándose sub-poblaciones temporalmente persistentes a lo largo de todo el Mediterráneo. En consonancia con los capítulos anteriores, la SST y Chla resultaron ser factores significativos en la definición de patrones de distribución y fluctuaciones interanuales de la abundancia. La segunda parte de la tesis estaba motivada por la situación actual de los cefalópodos en el Mar Mediterráneo, donde no existen medidas de evaluación y gestión específica para este grupo y algunas de sus poblaciones se encuentran sobreexplotadas. Para contribuir al conocimiento de la situación actual en el Mar Balear, se analizó la pesquería, ciclo vital y dinámica poblacional de la sepia utilizando series temporales intra-anuales (Capítulo 5). El análisis de diferentes factores ambientales reveló que la SST y la variabilidad climática local influían significativamente en las fluctuaciones de abundancia de la especie. En un trabajo posterior (Capítulo 6) se aplicaron técnicas de evaluación de stocks a las pesquerías de sepia y calamar de las Islas Baleares utilizando datos procedentes de la EU Data Collection Framework (DCF). Hasta donde sabemos, este trabajo constituye la primera aplicación de los Lesly-Delury Depletion Methods a stocks de cefalópodos del Mediterráneo. Los resultados demostraron que el esquema actual de muestreo de la DCF es inadecuado para la evaluación de cefalópodos y se proponen posibles modificaciones.
Els cefalòpodes constitueixen un grup faunístic important als ecosistemes marins, essent elements clau a les xarxes tròfiques. A més, són importants recursos pesquers i la seva contribució als desembarcs pesquers mundials s’ha incrementat en les últimes dècades. representant al voltant del 30% de la captura desembarcada a nivell mundial. Al Mar Mediterrani existeixen varis estudis locals sobre l’abundància i distribució de cefalòpodes, però pocs integren escales temporals llargues i àrees extenses. Aquesta tesi combina estudis sobre la composició de la comunitat, la diversitat i l’abundància de cefalòpodes a gran escala espaciotemporal (Part I) amb estudis a escala local al voltant de les Illes Balears (Part II). En primer lloc, es va realitzar un anàlisi de les comunitats de cefalòpodes a escala de tot el Mediterrani per descriure l’estat actual i determinar possibles diferències entre les sub-conques occidental i oriental (Capítol 2). L’objectiu fou comparar l’estructura de les comunitats faunístiques entre sub-conques i analitzar la influència de gradients ambientals a gran escala sobre la composició específica. Tot i que no s’observaren diferències significatives en la composició específica, les contribucions relatives de les diferents espècies variaren entre sub-conques. Degut al seu cicle vital curt i estratègia reproductiva semèlpara els cefalòpodes són molt sensibles als canvis ambientals, adaptant-se a ells amb relativa rapidesa. S’esperava, per tant, que factors ambientals com la temperatura superficial del mar (SST) i el contingut de clorofil·la a (Chla) fossin factors importants en l’estructuració de les comunitats de cefalòpodes. Si bé la seva importància va diferir entres les dues sub-conques, es va confirmar que la profunditat era el factor estructural més important en aquestes comunitats. S’analitzaren també canvies en la diversitat específica de les comunitats de cefalòpodes a escala de tot el Mediterrani durant els últims 20 anys (Capítol 3). Els resultats no mostraren cap tendència temporal ni espacial (latitud, longitud) clara i homogènia en la diversitat. Les úniques tendències temporals observades variaren entre diferents sub-regions, essent la posició geogràfica, profunditat, SST i productivitat els principals factors determinants d’aquestes tendències. Per tal de confirmar la importància de la variabilitat ambiental a nivell específic, es va investigar la influència de la SST i la producció primària en l’estructuració espacial i la dinàmica poblacional de dues espècies de cefalòpodes d’importància comercial (Capítol 4). Tot i que Octopus vulgaris i Illex coindetii tenen característiques vitals diferents i viuen en hàbitats diferents, les tendències temporals a llarg plaç en la seva l’abundància i el comportament sincrònic de les seves poblacions va ser similar, observant-se sub-poblacions temporalment persistents al llarg del Mediterrani. En consonància amb els capítols anteriors, la SST i Chla resultaren ser factors significatius en la definició de patrons de distribució i fluctuacions interanuals de l’abundància. La segona part de la tesi estava motivada per la situació actual dels cefalòpodes al Mar Mediterrani, on no existeixen mesures d’avaluació i gestió específica per aquest grup i algunes de les seves poblacions es troben sobre-explotades. Per contribuir al coneixement de la situació actual al Mar Balear, es va analitzar la pesqueria, cicle vital i dinàmica poblacional de la sípia utilitzant sèries temporals intra-anuals (Capítol 5). L’anàlisi de diferents factors ambientals va revelar que la SST i la variabilitat climàtica local influïen significativament en les fluctuacions d’abundància de l’espècie. En un treball posterior (Capítol 6) s’aplicaren tècniques d’avaluació d’stocks a les pesqueries de sípia i calamar de les Illes Balears utilitzant dades procedents de la EU Data Collection Framework (DCF). Fins on sabem, aquest treball constitueix la primera aplicació dels Lesly-Delury Depletion Methods a stocks de cefalòpodes del Mediterrani. Els resultats demostraren que l’esquema actual de mostratge de la DCF és inadequat per a l’avaluació de cefalòpodes i es proposen possibles modificacions.

Law can meet non-law. This is possible and true since the judicial process of adequacy of an abstract judicial solution to a concrete case imposes an adaptation to the applicable law. This is particularly correct in international law field because the law adaptation to its application brings it to open itself to foreign element of the law.This study intends to provide a theoretical systematization of the qualification and the use of extra-legal factor by the international judge.Reflexion must begin with a first identification of extra-legal factors in the legal thinking through an exegetic lecture of advisory proceedings and contentious cases. The identification of these elements strangers to law will allow the determination and the analysis of the criteria used by international judge(s) and the existence of an eventual classification between such different factors.If international judge accepts to have resort to lawlessness, this opening is not meaningless. Extra-legal factors’ scope on case law must be researched. It’s about a double scope, firstly normative and secondly substantial. Extra-legal factors do have indeed a role in the structuration of international law speech, once integrated to law, because they facilitate the different cases’ individualisation work through their helping role in facts’ interpretation and because they facilitate the decisions’ contextualization work as well, through an international rule shaping. They also have a role in the evolution of international rule since they contribute to the cultural diversity of the ICJ’s judges and, thereby, they become vectors of interdisciplinarity, while they allow an evolutive interpretation of international rule and they contribute to the opening to new tendances

Tiivistelmä Tiedonsiirron ja tiedonsiirtonopeuksien suuri kasvu sekä tehonkulutuksen pieneneminen tulevien sukupolvien matkapuhelinjärjestelmissä tekevät monihyppyiset matkapuhelinverkot houkutteleviksi vaihtoehdoiksi. Tässä työssä esitetään uusia tiedonsiirtoverkkojen paradigmoja monihyppyisten matkapuhelinverkkojen hyödyntämiseksi. Työssä esitellään uusi algoritmi tehokkaaseen releointitopologian hallintaan, joka optimoi yhtäaikaisesti topologian, reitityksen sekä lähetyshetkien ajoituksen ja mahdollistaa tila-aika-reititysprotokollan toteutuksen. Esitetty algoritmi huomioi solujen keskinäishäiriön ja vaaditulla solujen välisellä koordinoidulla hallinnalla saadaan yhdessä valittua topologia ja ajoitus, jotka minimoivat solujen keskinäisistä häiriöistä johtuvan suorituskyvyn heikentymisen. Myöhemmin tätä viitekehystä on laajennettu lisäämällä siihen tehonsäädön optimointi. Työssä on tutkittu sekä perinteisiä että kooperatiivisia releointimenetelmiä. Lisäksi työssä esitetään uusi geneettinen algoritmi heuristiseksi approksimaatioksi verkon liikenteen muutoksen vaatimaan releointitopologian uudelleen järjestelyyn. Työssä tarkastellaan lisäksi verkkokoodausta ylä- ja alasuuntaan tapahtuvan tiedonsiirron yhdistämiseksi sisällyttämällä se solujen keskinäishäiriön huomioivaan kahdensuuntaiseen releointiin. Etsittäessä paremmin mukautuvaa ja kontekstitietoisuutta hyödyntävää verkkomallia, joka käyttää hyväkseen viimeisimpiä verkkojen informaatioteoreettisia tuloksia, voidaan verkon solut pilkkoa pienempiin kuusikulmaisiin alisoluihin.

The distribution grid occupies a central position in the energy transition. This results in two key changes for the network: an (r)evolution of uses and a digital (r)evolution. In this context, this thesis begins by creating a new mapping of the uses of data from smart meters. Building upon this mapping, the thesis will delve into two central themes of great importance in the context of energy transition. The first is an analysis of the Diversity Factor of Low Voltage (LV) charges and its estimation. The second involves estimating the load curves of customers on the LV grid using an innovative method
Talagrand, Emilie. "Diversité, complexité et adaptation au comportement pathogène au sein du genre Aeromonas." Thesis, Montpellier, 2017. http://www.theses.fr/2017MONTT123/document.
Aeromonas groups ubiquitous bacteria mainly living in aquatic environments. These opportunistic pathogens for human and numerous animals have a large repertoire of virulence-associated factors. Although pathotypes were proposed and despite some species are more frequently isolated in human and animal infections, their pathogenicity is still poorly understood, mostly because very few comprehensive functional studies are available and because investigations taking into account the genetic diversity and the biological complexity within the genus are lacking.We assumed that for an opportunistic bacterial pathogen of environmental origin as versatile and ubiquitous as Aeromonas, the population structure in complex of species, the outstanding genetic/genomic diversity, the polymorphism of virulence factors and the interactions within pathogenic populations can act as factors driving the adaptation to a pathogenic behaviour. To test this hypothesis, we studied i) the diversification within “A. media”, a complex of species used as a model by a population study that included multilocus genetics, phylogenetics, evolutionary features, comparative genomics, as well as phenotypics, lifestyle and habitat ii) the patho-genomics of well-known virulence factors in aeromonads (aerolysin, thermolabile and thermostable enterotoxins, exotoxin A, serine protease, components and effectors of type III secretion system, and lateral flagellin) in a population that is representative of the known taxonomic diversity in the genus (30 species) and iii) the pathogenic behaviour using an in vivo model (Caenorhabditis elegans), an in vitro model (cytotoxicity, cytoadhesion, biofilm production, motility), and intercellular signals production (type I quorum-sensing) for populations involved in mixed aeromonosis, i.e. 5% of human aeromonosis defined by the isolation of at least 2 distinct clones.The phenomenon of speciation described in the complex “A. media” that aggregates 3 genomic species demonstrates that Aeromonas harbours a population structured in complexes of closely related species whose genetic and genomic diversity, as well as evolution mode (mutations and recombinations) reveal a wide adaptative and patho-adaptative potential linked to lineage emergence. Among the complex “A. media”, the species A. rivipollensis seems to be more adapted to a host-associated lifestyle and harbours specific genes for the resistance to environmental stress. Aeromonas has a wide range of virulence-associated genes, which presented diverse evolutive history. Some of them display a phylogeny linked to the core-genome evolution. These results suggest that these genes are involved in speciation processes probably related to niches adaptation. The evaluation of performances of virulence PCRs revealed major lacks of sensitivity of tested methods mainly due to the genetic polymorphism of the virulence factors. By using in vivo models and in vitro models, we also showed that Aeromonas mixed populations recovered from clinical samples could change the course of infection, likely through a cooperative or competitive mechanism that involves cell-to-cell signalling.The high complexity of Aeromonas results from its population structure, virulence factors polymorphism and multicellular behaviours. They are all putative adaptation factors to a pathogenic behaviour that may explain at least partially the difficulties encountered to elucidate pathogenicity of these bacteria

Segons la Directiva Hàbitats (92/43/ECC) un hàbitat es defineix com “una àrea aquàtica o terrestre, tant natural com seminatural, diferenciada per les seves característiques geogràfiques, biòtiques i abiòtiques, on les espècies hi viuen en qualsevol etapa del seu cicle de vida”. A més, d’acord amb la Directiva Marc d’Estratègia Marina (2008/56/EC), cada estat membre té l’obligació de caracteritzar la diversitat dels seus espais naturals marins mitjançant una cartografia dels hàbitats, representats per les seves característiques biòtiques i utilitzant sistemes de classificació apropiats. A Catalunya, per complir amb aquests requeriments, es va realitzar una cartografia exhaustiva dels hàbitats litorals, caracteritzant-los i identificant-los segons els sistemes de classificació CORINE Biotopes, EUNIS (European Nature Information System) i LPRE (Lista Patrón de los Hábitats Españoles), tant si es presentaven sobre roca, sorra, graves, còdols o fangs. La zona litoral pot ser dividida en tres estatges: supralitoral (rarament submergit i afectat regularment pels esquitxos), mediolitoral (emergit i constantment remullat per les onades), i infralitoral (habitualment submergit). Els organismes es distribueixen verticalment seguint el gradient d’humitat, tot generant una successió contínua de diferents comunitats/hàbitats des de l’estatge supralitoral fins a la part superior de l’estatge infralitoral. Les dades provinents de la caracterització, identificació i cartografia acurada dels hàbitats marins costaners rocosos al llarg de la costa catalana, han permès la realització d’aquesta tesi doctoral, la qual es divideix en tres capítols principals, dos dels quals ja han estat publicats en revistes científiques

The fashioning of the discontinuous takes various forms in the novels of Goncourt. It results from the construction of two brothers who have a particular interest in rare objects and details. In a bid to be modern, writers constantly criticize the idealist novel as a used form and show a preference for the whimsical model. In their attempt to "kill the romance", the authors of En 18 ..make the novel a space of freedom where they do not hesitate to break the linearity of the story, to break up the narrative material into small chapters, and to give the reader a terse text that solicits his collaboration. Consisting of several fragments of the Journal, the novel Goncourt becomes the reservoir of firsthand texts. The genesis of the work, thus, contributes to the creation of discontinuity and generates a great discursive and generic diversity that will become the source of the modernity of the Goncourt novels

The subventricular zone (SVZ) is a brain region that shows intense germinal activity throughout postnatal life. The postnatal SVZ is subdivided in microdomains containing neural stem cells (NSCs) that express defined transcription factors and generate distinct neuronal subtypes in the olfactory bulb (OB). Calretinin-expressing (CalR+) interneurons represent the largest population of OB periglomerular interneurons produced after birth. Yet, in contrast to others, limited information exists regarding their origin, diversity and function in the OB, as well as the transcription factors that guide their generation. Previous studies highlighted that CalR+ PG interneurons are generated by both the medial and dorsal SVZ microdomains, and suggested that the transcription factor Sp8 is involved in their generation.This work aimed at 1) refining current approaches for manipulating gene expression in postnatal SVZ NSCs in a temporally controlled manner, 2) exploring the origin and the function of CalR+ periglomerular neurons, 3) investigating the role of Sp8 in the transcriptional coding of CalR+ periglomerular interneurons specification and maturation.Refinement of the classical electroporation approach allowed the long-term fate mapping and timely-controlled genetic manipulation of NSCs of the SVZ. Using this refined approach allowed identifying two subpopulations of CalR+ interneurons that show different spatial and temporal origins after birth, as well as to explore the functional and morphological correlates of this diversity. A large and previously non-described fraction of CalR+ periglomerular interneurons exhibits properties of immature neurons (i.e. little synaptic inputs and weak excitability), questioning their role in olfactory processing. Finally, genetic manipulations of the transcription factor Sp8 at different stages during CalR+ interneuron differentiation highlighted its role in the long-term survival of mature CalR+ periglomerular interneurons, while excluding a role in their early specification. Altogether these results shed new lights on the origin, diversity and transcriptional coding of CalR+ periglomerular i nterneurons and call for a characterization of their role in olfactory processing

To what extent the inclusion of the religious fact by the organizations participates in the emergence of new managerial practices? That’s the problematic raised by our study which is built around five questions :1) What’s the state of the religious fact representations in organizations? 2) To what extent the representations of the religious fact determine the consideration's failover, positioning it in a favorable or unfavorable way ? 3) How a distribution of organizations by sector, by size ..., of postures adopted by organizations face to the religious fact would enlighten the understanding of this phenomenon? 4) What’s the managerial level the most solicited by organizations to deal with the religious fact? 5) At what treatment level, are the management practices more appropriate to avoid a reduced performance of human capital?

Els arqueus abunden en ambients extrems però també són un component rellevant dels sòls, del plàncton oceànic i lacustre i dels sediments. Molts estudis han destacat la importància dels arqueus en els cicles de nutrients dels sediments marins tant a escala local com global. En canvi, es disposa de menys informació sobre la diversitat, abundància i paper que juguen els arqueus en sediments d’aigua dolça a excepció dels metanògens. Com a dificultat afegida, la majoria d’arqueus sedimentaris no s’han pogut cultivar encara al laboratori, el que dificulta el seu estudi. La solució a aquests problemes passa per l’aplicació de tècniques moleculars que permeten la identificació i recompte dels microorganismes diana sense necessitat de cultivar-los. En aquesta tesi s’han combinat diferents tècniques moleculars (seqüenciació massiva i PCR quantitativa) per a conèixer la distribució, abundància i composició de les comunitats d’arqueus en sediments de sistemes aquàtics d’aigua dolça (llacs, llacunes i embassaments amb diferents condicions i tipologies). La tesi s’ha centrat en dos grups d’arqueus que són ubics i especialment abundants en sediments: el fílum Bathyarchaeota i la classe Thermoplasmata

Includes bibliographical references.
The aim of this study was to investigate some of the factors that are associated with support of diversity in the South African workplace. Three particular factors were considered: employees’ race and gender and the degree to which employees felt their socio-emotional needs for acceptance or empowerment had been addressed. The importance of satisfying individuals’ socio-emotional needs for them to be willing to engage with members of other groups is highlighted in Shnabel and Nadler’s (2008) Needs-Based Model of Reconciliation (NBMR), which states that groups are only willing to reconcile once their socio-emotional needs have been addressed. Furthermore, the model specifies that these needs are different for members of groups who were victims in a conflict situation compared to those who belong to the perpetrating group. While victims have a need for empowerment in order to be seen as equal players in society, perpetrators want to feel accepted in society and thus have a need for acceptance. Based on the literature reviewed the study’s first hypothesis stated that previously disadvantaged groups would place more value on diversity than previously advantaged groups and that women would value diversity more than men. The second hypothesis was that previously advantaged groups have a higher need for acceptance than empowerment and previously disadvantaged groups have a higher need for empowerment than acceptance. The last hypothesis proposed that the lower their need for empowerment, the more previously disadvantaged individuals would value diversity and the lower their need for acceptance, the more previously advantaged individuals would value diversity.

Our research focuses on the role of the management controller in insurance companies in a country belonging to a region of continuous economic and political disturbances such as Lebanon.Thus, our thesis aims to capture the conditions under which Lebanese insurance companies choose their management control practice, and more specifically to determine the different contingency factors that can influence the management control function of insurance companies in Lebanon.The use of two methodologies has provided an insight into management control practices in insurance companies in Lebanon.The exploratory study conducted within seven insurance companies highlighted the existence of two types of management control functions, which are distinguished by their relative autonomy vis-à-vis of the company general management.More particularly, the role of the management controller depends on his position within the structure, and his authority margin varies according to his hierarchical connection.A broader typology is then carried out by a thorough quantitative study using a survey conducted among sixteen Lebanese insurance companies.The quantitative study shed more light on the existence of three types of management control systems in Lebanese insurance companies: the organizational management control system, the shared management control system, and the general information system. The adoption of one of these three types differs according to several contingency factors such as the company’s size, the internationalization of the company, the nature of the shareholding ..., and also according to the conception of the management control function designated by the governance of the organization

Based on diet, microhabitat use and morphometry data, we investigated the importance of ecological and historical (phylogenetic) factors an anuran assemblage (16 species) in a urban fragment of Atlantic Rainforest in northeast Brazil. The niche breadth for microhabitat use was low for all species, while diet niche breadth was high for the majority. The main food categories were Coleoptera and Orthoptera, and the close related species showed distinct diet. The pseudo-community analysis indicated the presence of structure for diet and microhabitat use. The canonical phylogenetic ordination detected historical effects in microhabitat use and morphology for Hylidae and Leptodactylidae. However, none historical effect was found for diet. Then, we conclude that the structure found in null models is phylogenetic for microhabitat and ecological for diet. Nevertheless, it can be stated that recent perturbations could be more important in structure assemblage, due to low diversity and great diet plasticity of species, indicating possible ecological release.
A busca por padrões na partição de recursos é revela informações acerca das interações ecológicas das espécies. Baseando-se em dados da dieta, uso de microhábitat, morfometria nós investigamos a importância dos fatores ecológicos e históricos (filogenéticos) na organização de uma taxocenose de anuros (16 espécies) de um fragmento urbano de Floresta Atlântica no nordeste brasileiro. A largura de nicho de uso de microhábitat foi baixa para todas as espécies, enquanto a de dieta foi alta para a maioria. As principais categorias alimentares foram Coleoptera e Orthoptera, sendo que as espécies mais próximas filogeneticamente apresentaram dieta distinta. A análise de pseudo-comunidades indicou a presença de estrutura para dieta e uso de microhábitat. A análise de ordenação canônica detectou efeito histórico no uso de microhábitat e morfometria para as famílias Hylidae e Leptodactilydae, porém, nenhum efeito histórico foi encontrado para dieta. Com isso, concluímos que a estrutura encontrada nas análises de modelos nulos são de ordem filogenética para microhábitat e ecológica para a dieta. Contudo, pode-se afirmar que as perturbações recentes podem ser mais importantes na estruturação da taxocenose, em virtude da baixa diversidade e grande plasticidade alimentar das mesmas, indicando possível liberação ecológica.
