Tout comme de nombreux autres États sur le continent africain, le Bénin a entrepris, à partir des années 1990, une large réforme de ses services publics dans laquelle la justice occupe une place centrale. Parmi les premiers textes à faire l’objet d’une révision figure le Code des personnes et de la famille, censé promouvoir l’égalité des sexes, contrairement au droit « coutumier » jusque-là applicable à la majorité des familles. Avec les conflits d’héritage comme porte d’entrée, cette recherche avait pour objectif de réfléchir à l’appropriation de ce nouveau texte par différents types d’acteurs. En effet, les questions liées à la gestion et à la répartition de l’héritage sont fréquemment source de conflits à Cotonou et dans les localités voisines. De nombreuses familles saisissent les cours et tribunaux. Dans un contexte où les services publics sont souvent associés à la corruption et aux pratiques informelles, cette thèse envisage les spécificités du système judicaire béninois, la question de la place du droit pour les citoyens, dans le travail des juges et le fonctionnement des tribunaux, démontrant ainsi que les règles officielles sont loin d’être systématiquement contournées dans les administrations africaines.

It has often been acknowledged that political discourse is a genre that naturally allows for metaphor use. Moreover, recent research has demonstrated the importance of analysing the political impact of these metaphors: “Examining metaphors that appear in political discourse provides insights into the way speakers understand their situation, and how they seek to accomplish their ends” (Ritchie, 2013). Previous research (Perrez&Reuchamps, 2014) has demonstrated the usefulness of applying Steen’s three-dimensional model of metaphor analysis in communication to a corpus of political discourse. I therefore propose to apply this model to a particular type of elite discourse. The corpus used for this research consists of biographical interviews conducted with Walloon politicians, each describing at length their personal political career within the political dynamics of their country. This corpus offers an interesting ground of investigation because of its spontaneous and informal character. Moreover, most studies on the use of metaphors in political discourse tend to focus on elite discourse with the underlying assumption that elites might knowingly use metaphors to convince the audience. What is interesting with our corpus, is that the interviews do not have a clear addressee or audience. Analysing the form, and particularly the metaphor use of these interviews comes with a number of questions: (i) do politicians use metaphors in spontaneous discourse; (ii) if so, when and (iii) why do they use these metaphors, i.e. do they use them with a specific purpose, as for example explaining a complex political issue, or not? To assess the extent to which politicians use metaphors in spontaneous discourse, we conducted a corpus analysis by applying the MIPVU procedure (Steen et al., 2010) in order to identify potential metaphorical contexts. In line with Steen’s three-dimensional model, we subsequently analysed the identified metaphors by making a distinction between three different layers of metaphor, respectively at the linguistic, conceptual and communicative level.

We present the discovery and characterisation of the exoplanets WASP-113b and WASP-114b by the WASP survey, {\it SOPHIE} and {\it CORALIE}. The planetary nature of the systems was established by performing follow-up photometric and spectroscopic observations. The follow-up data were combined with the WASP-photometry and analysed with an MCMC code to obtain system parameters. The host stars WASP-113 and WASP-114 are very similar. They are both early G-type stars with an effective temperature of $\sim 5900\,$K, [Fe/H]$\sim 0.12$ and $T_{\rm eff}$ $\sim 4.1$dex. However, WASP-113 is older than WASP-114. Although the planetary companions have similar radii, WASP-114b is almost 4 times heavier than WASP-113b. WASP-113b has a mass of $0.48\,$ $\mathrm{M}_{\rm Jup}$ and an orbital period of $\sim 4.5\,$days; WASP-114b has a mass of $1.77\,$ $\mathrm{M}_{\rm Jup}$ and an orbital period of $\sim 1.5\,$days. Both planets have inflated radii, in particular WASP-113 with a radius anomaly of $\Re=0.35$. The high scale height of WASP-113b ($\sim 950$ km ) makes it a good target for follow-up atmospheric observations. [less ▲]

We report three newly discovered exoplanets from the SuperWASP survey. WASP-127b is a heavily inflated super-Neptune of mass 0.18Mj and radius 1.35Rj. This is one of the least massive planets discovered by the WASP project. It orbits a bright host star (V = 10.16) of spectral type G5 with a period of 4.17 days.WASP-127b is a low density planet which has an extended atmosphere with a scale height of 2500+/-400 km, making it an ideal candidate for transmission spectroscopy. WASP-136b and WASP-138b are both hot Jupiters with mass and radii of 1.51 Mj and 1.38 Rj, and 1.22 Mj and 1.09 Rj, respectively. WASP-136b is in a 5.22-day orbit around an F9 subgiant star with a mass of 1.41 Msun and a radius of 2.21 Rsun. The discovery of WASP-136b could help constraint the characteristics of the giant planet population around evolved stars. WASP-138b orbits an F7 star with a period of 3.63 days. Its radius agrees with theoretical values from standard models, suggesting the presence of a heavy element core with a mass of 10 Mearth. The discovery of these new planets helps in exploring the diverse compositional range of short-period planets, and will aid our understanding of the physical characteristics of both gas giants and low density planets.

Après une période de « dédiabolisation » et grâce à une base électorale croissante, de plus en plus de partis d'extrême droite européens se revendiquent aujourd’hui comme démocratiques. En écartant de la scène politique et médiatique leurs membres les plus violents, en respectant les procédures électorales et en proposant des programme alternatifs vis-à-vis des partis traditionnels, les organisations d’extrême droite s’intégreraient durablement au sein de nos systèmes politiques jusqu’à se présenter, dans certains pays, comme les véritables représentants du peuple, les défenseurs des libertés individuelles et les promoteurs d’une « véritable démocratie » loin des bureaucrates et technocrates de Bruxelles, loin des élites politiques et économiques qui ont confisqué le pouvoir aux citoyens. Liberté d’expression, laïcité, référendum, souveraineté populaire,… Autant de valeurs, autant de principes qui jettent la confusion dans un débat censé opposer la démocratie à l’extrême droite. Entre opposition et récupération, quels sont donc les liens qu’entretiennent les partis d’extrême droite avec la démocratie ? [less ▲]

Le sexe ratio secondaire, défini comme la proportion de mâles à la naissance, est de 52% chez les bovins, avec des variations selon les populations étudiées de 46 à 57%. Il est plus élevé lors des premières étapes du développement embryonnaire, et les conceptus mâles meurent proportionnellement plus au cours de la gestation que les conceptus femelles. Les facteurs de variation potentiels sont nombreux, mais peu d’effets sont unanimement observés. L’effet de la parité ou du statut social de la vache ne sont pas clairement démontrés. Les ovulations sur l’ovaire droit donneraient naissance à une plus forte proportion de mâles ; le rôle du taureau est probablement limité et la répétabilité du sexe du veau d’une gestation à l’autre est faible. Le moment de l’insémination par rapport à l’ovulation ne semble pas avoir d’influence alors qu’il aurait pu constituer un moyen de maîtrise assez simple à mettre en œuvre. [less ▲]

Despite some improvements in malaria control, this parasitic disease remains a major public health problem in many African countries, causing about 400 000 deaths/year through the continent, mainly by children under the age of five (WHO, 2015). In Guinea, the leaves of Mezoneuron benthamianum Baill. are traditionally used to treat malaria (Traore et al., 2013) and showed a good antiplasmodial activity in an antiprotozoal in vitro screening (Traore et al., 2014), as well as promising results in a preliminary small-scale ethnomedical study (unpublished data), encouraging us to continue the study of this plant. The aim of this work was to evaluate the activity of M. benthamianum leaves extracts against P. falciparum using an in vitro test model (p-LDH assay) and to undertake a bio-guided fractionation to identify the compounds responsible for the activity. Hydroethanolic extracts (70% v/v) of M. benthamianum leaves showed a moderate in vitro activity against P. falciparum 3D7, with IC50 = 22.5 – 32.6 µg/ml, depending on the batch; while a dark precipitate formed during ethanol evaporation showed higher activity (IC50 = 6,5µg/ml). The bioguided fractionation was performed on this most active fraction and allowed the isolation of three diterpens, two flavonoids, resveratrol, gallic acid and its ethylester, β-sitosterol glucoside and pheophorbide derivatives. The active compounds belong to several phytochemical classes, including flavonoids, pheophorbide and gallic acid derivatives, contributing together to the global antiplasmodial activity of the hydroalcoholic extract against P. falciparum parasite. This study gives some concrete evidence to support the ethnopharmacological use of Mezoneuron benthamianum leaves extract in the management of malaria. The active compounds can be further studied for their antiplasmodial potential, as well as their suitability to be used as quality markers for the standardization of this herbal drug from the Guinean traditional pharmacopeia.

One of the basic rules in trade law is the freedom of trade. However, such rule encounters some limitations, derogations and exceptions when the object of trade is constituted by strategic and sensitive items. The concept of “strategic trade” is one of the most ambiguous ones, and there is not a common definition of it. Even if the General Agreements on Tariffs and Trade (GATT) does not offer such an explanation, its Article XXI can be construed as referring to strategic trade, as much as it states that the provisions of GATT (grounded on free trade) need not apply in cases where “essential security interests” are involved. The concept of “essential security interests” is also vague, as it is left upon the individual parties to the GATT to decide what it means. Despite such ‘slippery slope’ in the definition of terms, it results, however, that strategic trade is linked to norms and measures that aim at controlling trade, in order to ensure the protection of non economic needs, such as national security, public morals, public order, etc. This area finds at the intersection of commercial and foreign policy. For ensuring the protection of non economic interests, it is necessary to introduce measures that provide for controls on all activities conducted by individuals, organizations, and groups regarding goods, equipment, materials, services related to strategic items: these activities shall cover the whole supply chain, including design, development, production, possession, delivery, transport, transit, trans-shipment, financing, brokering, exports, re-exports, transfers and imports. The actors intervening in the draft of rules and controls are mainly the States, and the international and regional organiza- tions; then, important subjects are national licencing authorities and enforcement agencies such as customs, border security, police and armed forces, if needed. The targets of such measures of control could be the States, if the rules at the international or regional level are addressing them, and/or the operators involved in strategic trade. Considering the ways in which States organize such controls, the reality shows that they have introduced control lists, licences and authorisations granted on the basis of conditions and criteria, information-sharing and cooperation between authorities and operators, duties of transparency through reports, records, dec- larations and screenings. Moreover, measures exist that consist of restrictions, bans and penalties providing that consequences in case of violation of strategic trade rules. Therefore, the issue of sanctions is a relevant part of the strategic trade law, and it inserts within that context. The purpose of this contribution is to define what sanctions in strategic trade mean and to systematize them accordingly. In particular, the sanctions are categorized into three groups: A. “supranational sanctions”; B. “implementing sanctions”; C. tertium genus: “unilateral sanctions” and “countermeasures”. [less ▲]

We propose a simple but fundamental methodological change to Fama and French (1993) factor construction procedure. Consistent with Lambert and Hübner (2013) sequential sorting procedure to classify stocks, our methodology controls ex ante for pricing errors produced by multifactor models. Our size and value factors deliver less specification errors when used to price portfolios, especially regarding low size and high B/M stocks. Furthermore, this alternative framework generates much stronger “turn-of-the-year” size and “through-the-year” book-to-market effects than conventionally documented. The factors also display a slight competitive advantage on the taxonomy of low turnover market anomalies defined by Novy-Marx and Velikov (2015). [less ▲]
