BACKGROUND: In Gabon, several Ebolavirus outbreaks have occurred exclusively in the northeastern region. We conducted a large serosurvey to identify areas and populations at risk and potential demographic, clinical, and behavioral risk factors. METHODS: Blood samples and clinical and sociodemographic data were collected from 4349 adults and 362 children in a random sample of 220 villages in the 9 provinces of Gabon. An enzyme-linked immunosorbent assay was used to detect Zaire ebolavirus (ZEBOV)-specific IgG, and thin blood smears were used to detect parasites. Logistic regression was implemented using Stata software (Stata), and a probability level of <.05 was considered to be statistically significant. RESULTS: The prevalence of ZEBOV-specific IgG was 15.3% overall, increasing to 32.4% (P< .001) in forest areas. No sociodemographic risk factors were found, but the antibody prevalence increased linearly up to 20 years of age. Chronic arthralgia and amicrofilaremia were the only factors associated with ZEBOV seropositivity. CONCLUSIONS: These findings confirm the endemicity of ZEBOV in Gabon and its link to the ecosystem. Human antibody positivity would appear to be to the result of exposure to contaminated fruits. [less ▲]

The TCLUST procedure is a robust clustering procedure that performs clus- tering with the aim of tting clusters with di erent scatters and weights. As the corresponding objective function can be unbounded, a restriction is added on the eigenvalues-ratio of the scatter matrices. The robustness of the method is guaranteed by allowing the trimming of a given proportion of observations. The resistance to contamination of that procedure will be studied. Results con- cerning breakdown points and some new criteria in robust cluster analysis, such as the dissolution point and the isolation robustness, will be presented. [less ▲]

According to the current semiotic hypothesis in the studies of enunciation, we assume negation is to be found in the relations between signs as well as in their semantic differences, and not in positive realizations of such signs. In the study proposed here, negativity arises from the contrasts of figures, not only because of the opposition between signs themselves, but also because the values apprehended testify a questioning of some artistic and scientific fields. Our paper discusses thus an artistic installation by the Belgian-Israeli artist Dany Danino. The contrast between figures reveal the different fields mentioned in his work – architecture, mathematics, anatomy and also the arts. At the same time that they are cited and assumed, these fields are also the target of some sort of negation. This negative form is, however, not expressed in the signs. It is established in the contrastive syntagmatic organization that creates dynamic relations between the parts and the installation as a whole, as well as its socio-cultural context and its exposition setting. Français : Selon l’hypothèse en vigueur en sémiotique énonciative, nous supposons que la négation se présente, toujours de façon partielle et plus ou moins cachée, dans les relations entre signes ainsi que dans leurs différentiels sémantiques plutôt que dans des formes positivement présentées. Dans l'étude qui est ici proposée, la négativité surgit du contraste des figures, non seulement en raison de l'opposition entre les signes eux-mêmes, mais aussi parce que les valeurs qui s’en dégagent peuvent témoigner d'un questionnement à l’égard des champs artistiques et scientifiques convoqués dans l’œuvre. Notre analyse porte ainsi sur une installation de l'artiste belgo-israélien Dany Danino. Le contraste entre les figures montre que les différents champs en présence — l'architecture, la mathématique, l'anatomie et les arts plastiques eux-mêmes —, dans le même temps qu'ils sont cités et assumés, sont visés par une forme de négation. Or cette forme négative n’est pas connotée dans les signes. Mais elle s’instaure dans un agencement syntagmatique contrastif qui rend dynamique les relations des parties avec le tout de l’installation, en ce compris son contexte socio-culturel et sa situation d’exposition.

Je me propose de réévaluer un certain aspect de l’héritage de Lotze, à savoir sa théorie de la validité (Geltung). En m’inspirant notamment d’une remarque de Georg Misch, qui fut l’éditeur de la troisième édition du système de Lotze en 1912, et de certaines déclarations de Husserl, je défendrai la thèse suivante : la théorie lotzéenne de la validité appartient à une tradition qui se caractérise par la découverte de propositions aprioriques d’un certain genre, à savoir des relations of ideas (au sens de Hume), des lois aprioriques matérielles (au sens de Husserl) ou des axiomes objectifs, régionaux ou matériels (au sens de Stumpf). Ce que je voudrais suggérer, en un mot, c’est qu’il y a une connexion étroite entre le concept lotzéen de validité et la découverte de l’a priori matériel. [less ▲]

Public diplomacy is an international political communication activity that experienced renewed importance in the United States after the 9/11 terrorist attacks. The War on Terror promoted by the Bush Administration was accompanied by the implementation of public diplomacy strategies designed to reinforce the fight against terrorism and to diminish the levels of anti-Americanism, especially in the Muslim world, through the exercise of soft power. The object of this thesis is, in the first place, to study public diplomacy as an international political communication activity. In the second place, to carry out empirical research that, resorting to framing theory as a methodological tool, analyzes and evaluates the influence of Bush¿s declarations and speeches, as a part of American mediatic diplomacy, in the Spanish press, in two case studies on the War on Terror (the first case study spans the period from 9/11 to November 2001, and the second, the months prior to the Iraq War). To do so, the content of this thesis is set out in six chapters. The first chapter presents a theoretical framework of public diplomacy, the second chapter explains the methodology that is used in the empirical study and the third chapter offers a context for the case studies where that methodology is applied. Chapters four, five and six constitute the empirical part of the work: in the first two the results of the analysis of mediatic diplomacy in two specific periods of the War on Terror are exposed, and, in the last, an evaluation of its influence based on the results of the analysis and on the consideration of other relevant factors is performed.

The present work is devoted to an ab-initio characterization, using planewave and localized basis sets, of multiferroic and magnetoelectric materials. After a general description of the underlying concepts and computational techniques, we focus on BiFeO3, which is probably the most intensively studied multiferroic. We start our investigation by comparing the ability of different exchange-correlation functionals (LSDA(+U), GGA and hybrid) to accurately describe the most fundamental properties of BiFeO3 (crystallographic structure, electronic band structure, magnetism, phonons at Gamma, Born effective charges). Next we present infrared reflectivity and Raman spectra obtained from first-principles and compare them to experimental data. We then extend the study of the dynamical properties of BiFeO3 to the whole Brillouin zone by analyzing the phonon band structure, density of states and interatomic force constants. We also use combined Einstein and Debye models to fit the specific heat as obtained from first-principles and compare it to experimental data. The final part of this thesis is devoted to the investigation of pressure driven spin phase transitions in Bi2FeCrO6 . [less ▲]
