Le succès des candidatures populistes dans de nombreux pays depuis 2014 illustre une fragilisation de l'alignement électoral des masses observé depuis la fin de la deuxième guerre mondiale. Elle semble le fruit à la fois de la multiplication des moyens d'information de masse et de la désaffiliation des organisations qui avaient polarisé les systèmes politiques. [less ▲]

Notre conférence introduit une journée table ronde rassemblant des acteurs clés pour le développement d'une qualité d'accueil dans les différents cantons suisses. Ceux-ci considèrent que l’accueil et l’éducation de la petite enfance ainsi que le soutien aux familles contribuent à l’égalité des chances, à la cohésion sociale et à la prospérité économique. Pour que ce rôle essentiel soit mieux reconnu au niveau politique et dans la société en général, la Suisse a besoin, selon eux, d’une politique globale de la petite enfance visant des objectifs précis et produisant des effets durables. Notre conférence propose une réflexion sur le développement d'une qualité d'accueil définie de manière contextualisée et sur les conditions de sa mise en oeuvre dans un "système compétent", en accordant une attention particulière aux enjeux de professionnalisation.

L’enquête policière d’homicide est un processus très complexe en raison des particularités inhérentes à la gravité du crime commis et les nombreuses activités et procédures d’investigation menées par les enquêteurs pour identifier l’auteur des faits et élucider le crime. À travers les données d’homicides commis en Algérie entre 2011 et 2014, les résultats de recherche présentés offrent un aperçu inédit des facteurs à l’origine de l’élucidation de ce type de crimes dans une région du monde où les informations sur ce sujet sont plutôt rares. Bien que le débarquement de nouvelles méthodes d’enquête, qui s’appuient sur des moyens technologiques et scientifiques récents (à l’exemple de l’identification génétique d’ADN), semble avoir bousculé aussi bien les procédures traditionnelles d’investigation que les mentalités et les attitudes des enquêteurs, l’examen des facteurs d’élucidation des cas examinés met en évidence au moins trois constats majeurs. D’abord, la contribution modeste des efforts d’enquête dans la résolution des affaires d’homicide, accomplie à la faveur de l’attitude du meurtrier qui avoue spontanément son crime. Ensuite, l’apport marginal de l’expertise scientifique dans l’identification des auteurs. Enfin, la prééminence des facteurs humains et relationnels (témoignages, aveux spontanés, dénonciation), comparés aux facteurs matériels (constatations, investigations techniques, expertise criminalistique).

Periurban agriculture increased vegetables production in the cities. A survey was conducted in three market gardening in Libreville and Owendo cities to register crop and pesticides diversity uses by farmers. The most abundant cultivated species throughout the year appeared to be amaranth (Amaranthus ama L. Amaranthaceae). The most important pests were aphids (Hemiptera: Aphididae) and some beetles (Coleoptera). To control the pests, conventional neurotoxic insecticides were used with effect on environment and human health. In order to identify the occurring insects in the selected areas, a monitoring of insects was carried out during two years on amaranth, roselle, tomato (Lycopersicon esculentum M., Solanaceae) and cabbage (Brassica oleracea L., Brassicaceae). Entomological abundance and diversity were assessed through weekly trapping and visual observations from July to August each year. Insects were collected, identified at the taxonomic level of the family, and classified into three categories: pests, beneficials and associated insects to agriculture. Eighty four families belonging to height orders were recorded with 7910 and 3148 sampled individuals in 2012 and 2013 respectively. The predominant insect families were in both years Aphididae, Cecidomyiidae (Diptera) and Chrysomelidae (Coleoptera) for pests, Dolichopodidae (Diptera), Staphylinidae (Coleoptera) and Coccinellidae (Coleoptera) for beneficials, and Muscidae (Diptera), Psychodidae (Diptera) and Formicidae (Hymenoptera) for associated insects. As aphids are the most important pests, further study at species level and in relation to predatory beneficials were assessed on vegetable crops in 2013 in two periurban gardening sites. The Aphis craccivora Koch aphid was the most abundant aphid species observed infesting amaranth in both sites. The other aphid species were Lipaphis erysimi Kaltenbach, Myzus persicae Sulzer, Aphis fabae Scopoli and Aphis gossypii Glover. Moreover, seven species of natural enemies were trapped, mainly predatory hoverflies (Diptera: Syrphidae) and ladybirds (Coleoptera; Coccinellidae). A. craccivora Koch is known to be a vegetable pest. Its recent identification as pest in amaranth motivated us to study their multitrophic interactions. Since relationships between aphids and host plants could be related to symbiont and feeding behaviour. A. craccivora endosymbiont bacteria and saliva protein diversity were analysed to explain plant–aphid interactions. Indeed, Buchnera aphidicola was found. Some proteins were only identified in solid and soluble saliva, while others originated from Serratia sp. endosymbiont. Two of the identified proteins are involved in plant-pathogen interactions: calmodulin and elongation factor Tu. To control A. craccivora which causes several crop damages, volatile organic compounds (VOC) have been studied. Only aphid alarm pheromone (E)-β-farnesene (EβF) was identified and quantified. Its effect on escape behaviour in aphids has been demonstrated on three species. A. craccivora responded more strongly than the two other Aphidinae (M. persicae and A. fabae) species with 78% of the individuals initiated dispersal behavior at 500 ng dose of EβF. In another laboratory study, the repellency effect of (E)-β-farnesene, methyl salicylate and two essential oils of basil species (Ocimum gratissimum L. and Ocimum basilicum L. Lamiaceae) were determined, while no repellent effect was observed. Also, aphid populations were reduced by exposure to EβF and O. gratissimum essential oil. This study is one of the few to explore the description of insects in the market gardens of Libreville. This could contribute to the elaboration of the sustainable development strategies of pest control in the zones. [less ▲]

The binomial coefficient (u,v) of two finite words u and v (on a finite alphabet) is the number of times the word v appears inside the word u as a subsequence (or, as a "scattered" subword). For instance, (abbabab,ab)=4. This concept naturally extends the classical binomial coefficients of integers, and has been widely studied for about thirty years (see, for instance, Simon and Sakarovitch). In this talk, I present the research lead from October 2015 on an extension of the Pascal triangles to base-2 expansions of integers. In a first part, I define two new objects that both generalize the classical Pascal triangle and the Sierpinski gasket. In a second part, I define a new sequence extracted from the Pascal triangle in base 2 and study its regularity. In a third part, I exhibit an exact formula for the behavior of the summatory function of the latter sequence. [less ▲]

Malignant pleural mesothelioma (MPM) is an aggressive cancer of the pleura mainly caused by asbestos fibers exposure. MPM is notably characterized by a very poor prognosis and current treatments, including radiation and chemotherapy, are unsatisfactory. As genomic analyzes show that the major mutations occurring in MPM cells pertain to checkpoint control and DNA repair, a first part of this thesis addresses the DNA damage response and the mechanisms of DNA repair in several MPM cell lines. In this study, we show that gamma ionizing radiation (IR) induces cell cycle arrest of MPM cells at the G2-M checkpoint. We also demonstrate that MPM cells are driven prematurely towards mitosis following the abrogation of IR-induced G2 arrest by the checkpoint inhibitor UCN-01, however without a significant induction of cell death. To avoid excessive genomic instability, DNA repair mechanisms are likely to play a key role in such DNA-damaging conditions. We therefore evaluate here the efficiencies of the two main DNA double-strand break repair mechanisms, non-homologous end-joining (NHEJ) and homologous recombination (HR) and highlight differences in such repair activities among MPM cell lines and in comparison to control mesothelial cells. We underline an efficient HR repair in MPM cells, opening the door to additional investigations that might reveal an addiction to activated DNA repair pathways and thereby render MPM cells hypersensitive to targeted combination therapies. In the second part of this thesis, we perform a pre-clinical study investigating the resistance of MPM to a particular epigenetic-based therapy associating the histone deacetylase (HDAC) inhibitor valproic acid (VPA) and doxorubicin. By comparing MPM cell lines with a differential sensitivity to this combination chemotherapy, this study suggests a correlation between transforming growth factor-alpha (TGF-α) expression and resistance to treatment. We further confirm the role of TGF-α in chemoresistance by modulating its expression in highly- and poorly responsive MPM cell lines. In addition, pharmacological inhibition of TGF-α’s receptor (EGFR or epidermal growth factor receptor) by tyrosine kinase inhibitors gefitinib and erlotinib improves the efficacy of VPA+doxorubicin in vitro. Dual HDAC-EGFR inhibitor CUDC-101 furthermore synergizes with doxorubicin to induce apoptosis in vitro and to slow down tumor growth in two different MPM mouse models, emphasizing its therapeutic potential and opening new prospects for combination therapies associating HDAC and EGFR inhibition against MPM. With two different approaches, this thesis provides a better understanding of MPM resistance to chemo- and radiotherapies and offers clues for new therapeutic strategies based on DNA repair pathways and dual HDAC-EGFR/TGF-α inhibition.

The author explores the practices through which migrant domestic workers established Transnational Voluntary Kin relations with individuals who are non-blood or law-related. Transnational Voluntary Kin are intimate relationships, which alleviate migrants’ reproductive needs by replacing, overlapping or complementing traditional family support. Drawing from Braithwaite, Bach, Baxter, Hosek, & Wolf [(2010). Constructing family: A typology of Voluntary Kin. Journal of Social and Personal Relationships, 27(3), 388–407] four relationships are explored. Firstly, there are ‘More than family’ Kin that replace the care of absent or dead family members. Secondly, there are ‘Just like Family’ Kin that replace the care of physically proximate relatives unable to perform their roles. Thirdly, there are ‘Whenever needed it’ Kin that replace or overlap traditional kin aid in particular situations. Fourthly, there are ‘In law or extended’ Kin constructed through the marriage of traditional kin. Data are drawn from a multi-sited ethnography with Peruvian-Colombian migrant domestic workers and their Transnational Voluntary or Traditional kin. The analysis contributes both to the constructivist sociology of the family and transnational family studies where these relationships remain underexplored. [less ▲]
