Face la population transnationale d’origine latino-américaine croissante à travers le monde – spécialement présente en Espagne et aux États-Unis – je me suis intéressée à la création littéraire en tant que mise en récit de Soi et de l’Autre. Dans le cadre de cette littérature latinoaméricaine de la migration, je me centrerai sur la représentation du genre dans ces romans, c'est-à-dire sur ces attitudes performatives qui (re)produisent les normes et les modèles mais aussi parfois des corps a-normatifs et illisibles (Butler, T. de Lauretis). Je proposerai donc d’articuler la notion stimulante de performance de genre telle que proposée par J. Butler à celle d’ethos rhétorique (Amossy, Maingueneau) dans le but d’analyser la voix narrative du roman The Brief Wondrous Life of Oscar Wao de Junot Díaz (2008). Cette lecture nous permettra de mettre en lumière le jeu de va-et-vient par rapport aux stéréotypes de genre qui font autorité et, plus fondamentalement, la construction d’un corps queer apatride qui s’oppose "naturellement" au corps masculin de la diaspora.

A novel, multidimensional on-line SPE-LC method with electrochemical detection is described for the fully automated and direct analysis of the catecholamines norepinephrine, epinephrine and dopamine in urine. The integrated extractive clean-up of the raw biofluid is based on a SPE-column packed with restricted access material (RAM) which is modified with the affinity ligand nitrophenylboronic acid. The method was fully validated according to a recent approach based on an accuracy profile. The acceptance limits were set at +/- 15% of the nominal concentration values. The method was found accurate over a concentration range from 15 to 500 mu g/l for norepinephrine, from 5 to 500 mu g/l for epinephrine and from 50 to 500 mu g/l for dopamine. The relative risk for the use of the validated method in routine analysis was also assessed based on this validation strategy. It was found that at most 3.5% of future sample measurements will fall outside the acceptance limits. This demonstrates the high reliability of the analytical method described. Moreover, the measurements uncertainties were deduced from the validation experiments without any additional effort. (c) 2006 Elsevier B.V. All rights reserved. [less ▲]

As building insulation level increases, the coupling of ventilation systems with building enveloppe airtightness becomes an important issue in order to improve buildings energy performances. A building ventilation model can be built on a set of resistances and generators in order to handle infiltration, natural ventilation as well as fan driven air flows. The model is able to assess the indoor air humidity level and the building energy balance. Double flow ventilation can be handled through decentralized air handling terminals (DAHT), integrated in window ledges. A model of DAHT can be combined with the model of a whole building envelope, including infiltrations as well as dynamic behaviour, allowing comparisons with classical ventilation systems, such as natural or hybrid systems, or with centralized double flow systems. Results regarding energy consumptions, air humidity levels and superficial condensation risks can be analysed. Fresh air flow can be calibrated in order to meet air quality standards related to indoor humidity level and CO2 concentration. The modelization of buiding indoor hygro-thermal climate allows a complete assessment of the seasonal heat exchanger efficiency, including heat recovery through the condensation of indoor air humidity when it flows through the exchanger.

This paper proposes a survey of the performances of binary classifiers based on low-level audio features, for music similarity in large-scale databases. Various low-level descriptors are used individually and then combined using several fusion schemes in a content-based audio retrieval system. We show the performances of the classifiers in terms of pruning and loss and we demonstrate that some combination schemes achieve a better performance at a minimum computational cost. [less ▲]

The special properties of volume phase holographic gratings make them promising candidates for spectrometry applications where high spectral resolution, low levels of straylight, and low polarization sensitivity are required. Therefore it is of interest to assess the maturity and suitability of volume phase holographic gratings as enabling technologies for future space missions, with demanding requirements for spectrometry. One of the main areas of research is related to grating ageing under space radiation. In the present paper, two volume grating technologies are analyzed and compared under gamma irradiation. The performances of both technologies, the photo–thermo–refractive glass and the Dichromated Gelatin, are tested on samples and assessed in the and near-infrared bands. The diffraction efficiency degradation under gamma irradiation is assessed. [less ▲]

Nowadays, Belgian poultry breeding is characterized by a strong biodiversity that is nevertheless greatly endangered. The present work aims at evaluating the zootechnical potential of an ancient poultry breed originating from the Franco-Belgian Ardennes region, the Ardennaise. This breed shows an important phenotypic variation, with 10 different varieties being recognized. This study evaluates the Ardennaise production performances and is divided into three parts: (1) the analysis of the growth and the consumption indices over a twelve weeks period, (2) the comparison of the growth over seventeen weeks in four varieties, (3) the study of eggs number and eggs weight over 70 weeks laying. The results indicate that the Ardennaise breed constitutes a good dual purpose breed that could be interestingly submitted to selection. Its use in industrial crosses for egg composition amelioration is also proposed. Lastly, this works shows the importance of extending the here developed evaluation protocol to other Belgian endangered poultry breeds to motivate the necessary conservation programs. [less ▲]

This paper will approach the celebrations of the canonization of St. Ignatius and St. Xavier in different localities of the Southern Netherlands over the course of 1622 as performances of emotion. We will analyze little known visual and textual testimonials of festivals and theatrical representations in Antwerp, Douai, Brussels, Dunkerque and Leuven to examine which means were used to represent, convey and enhance emotions, which actors were involved, how emotions were meant to address and affect the audience, and to what end emotions were activated. The double canonization of 1622 consecrated the Jesuits as stalwarts of the Roman papacy. In the Southern Netherlands, the celebrations of 1622 were a key moment in confirming the legitimacy of the order by displaying both how it was embedded in the local political and religious arena, and how it mastered the most advanced artistic means to support its mission. After a sketch of the celebrations and their political and religious context, we will analyze how and why emotion was performed in three steps. The sources attach enormous attention to the material, architectural and urban setting of the celebrations, by emphasizing the splendor and artistic sophistication of the events, and by pointing out the prestigious patronage that had accrued around them. We will examine whether and how the sources charged the material context of the celebration with emotion. What was the intended effect of this context on the audience? How did this context enable the performance of emotion in different forms of public display (pageantry, performances, …)? In order to answer this last question, in a second step we will have a closer look at the Triumphus dedicated to St Ignatius and St. Xavier performed in Brussels. We will examine how, in this ensemble, the material context is activated by the movement of the viewer. The description of the Triumphus singles out moments of transition as instances of heightened emotivity, suggesting that emotions are not mobilized by singular details but by overall views that impress themselves when the beholder crosses a treshold. In a third step we will describe the intended effect of the performance of emotions as a sacer horror, the bodily manifestation of religious awe, the organic sensation of respect mixed with fear and wonder felt in the presence of gods or cosmic forces. The performance of emotions, engendered by multiple layers of transformation (of the material context by means of ephemeral architecture, of the views and the experiences of the viewer, and ultimately, of their affective state) was directed at effectuating a lasting change of heart.

Interactions of malignant or non-malignant human and rodent cells with the vascular wall were studied using perfused human umbilical cord veins. The integrity of perfused endothelium was confirmed by morphological and functional criteria. Highly malignant cells in vivo adhered to the endothelial cells, as shown by scanning electron microscopy. The specific attachment of radiolabelled malignant cells to the whole vein was already maximal within 30-60 min and remained stable for perfusion flow rates ranging between 10 and 60 ml/min. It increased proportionally to the number of cells infused and could be modulated by human platelets, human fibronectin and rabbit anti-laminin antibodies. In contrast, the binding of human or rodent non-malignant cells in vivo, of human red blood cells and of human platelets to the endothelial cells was negligible under similar experimental conditions. This perfusion system therefore represents a new model for elucidating some mechanisms involved in tumour cell arrest in vivo. [less ▲]

A study was carried out in Niamey (capital city of Niger) to explore the market gardening periurban system. This activity is an option to minimize the risk of urban food insecurity in the Republic of Niger. In Niamey, you have two traditional areas to practise the market gardening production: Gamkalle and Yantala. The investigations study the area of Gamkalle. This study revealed more than 600 market gardening producers in Gamkalle. 50 producers of Gamkalle have been interviewed. These producers predominantly belong to the ethnic group “Zarma” and market gardening is their main economic activity. The principal period of production is during the dry season, the producers cultivate lettuce, cabbage, tomato, sweet pepper, beetroot, celery, carrot, parsley. Despite the higher costs notably in particular for input, the incomes generated by this activity are very high ($ 2805.23/year/acre). In conclusion, market gardening presents an opportunity for urban dwellers to increase and diversify their incomes and obtain food security. Nevertheless, there are many constraints to develop this production: land tenure security, pollution by industrial production and access to quality seeds, pesticides and fertilizers. [less ▲]
