Trajectoire de la réforme de l’inspection en Belgique francophone

L’article montre que la trajectoire de la réforme de l’inspection en Fédération Wallonie-Bruxelles (FWB) est loin d’être linéaire. Elle est marquée par des processus de reconversion institutionnelle d’institutions existantes, mais aussi de sédimentation et d’hybridation entre l’« ancien » et le « nouveau ». En effet, elle participe à la fois d’une politique de changement institutionnel ambitieuse et de construction du « système scolaire » dans un paysage au départ assez décentralisé et fragmenté ; mais, simultanément, elle est marquée par des « contraintes » institutionnelles existantes, des négociations et transactions entre différents acteurs politiques et scolaires qui déterminent les contours et les compétences du nouveau corps d’inspection en gestation après le décret de 2007 comme les rôles des inspecteurs et leur division du travail avec d’autres acteurs. De plus, dans la mise en œuvre du décret, les orientations normatives, cognitives et professionnelles des acteurs, la permanence de la diversité institutionnelle des réseaux comme la variance structurelle des territoires « modulent » et « tempèrent » l’ambition du changement institutionnel affiché par la politique de la FWB. Cela change mais pas complètement : il y a un processus de conversion partielle et « en tension » de l’institution qu’est l’inspection.

A segunda vida da Praia dos Espanhóis: dançarinos, pescadores e turistas no sul de Portugal

Abstract: In this text, we deal with proccesses of appropriation of space in the Dam of Póvoa (Portugal) using a dwelling perspective (Ingold 2009) over the territory. The reconversion of innactive spaces in rural areas into leisure-related ones in a quite common practice in contemporary times.The Spaniards beach is one of the local names given by locals to the Dam of Póvoa (Castelo de Vide), in northern Alentejo (Portugal). In the collective memory of the residents, the Dam (built in the 1920’s) is remembered for the many flowers surrounding the area. This Garden-style aesthetics has outlived the initial function of the Dam (to produce electric power). From the 1960’s to the 1980’s, it was also a popular leisure space for Spanish and Portuguese people. It is not a beach, but being inland, it was the closest thing to a beach the residents had. The centrality of this leisure space in the area only decayed after the construction of swimming pools in the nearby towns. Early in the begginning of 21st century a fire destroyed part of the natural floral landscape of the dam. Abandoned for some years, the place has still been appropriated by leisured people in day-trips (for sight-seeing, pic-nics), fishing competitions, caravan soujorns, and, since 2013, in a music and dance festival named Andanças (www.andancas.net). The research that underlies this paper was carried out between 2013 and 2016 by a team of anthropologists. An ethnography of the Dam and its uses, and of the festival and its participants was carried out. In our working-paper we higlight the main research findings achieved. Key-words: Leisure; Landscape; Tourism; Music; Space; Portugal.

Design and evaluation of aerosol and liquid separation systems

Conventional chromatographic columns are packed with porous beads by the universally employed slurry-packing method. The lack of precise control of the particle size distribution, shape and position inside the column have dramatic effects on the separation efficiency. In the first part the thesis an ordered, three-dimensional, pillar-array structure was designed by a CAD software. Several columns, characterized by different fluid distributors and bed length, were produced by a stereolithographic 3D printer and compared in terms of pressure drop and height equivalent to a theroretical plate (HETP). To prevent the release of unwanted substances and to provide a surface for immobilizing a ligand, pillars were coated with one or more of the following materials: titanium dioxide, nanofibrillated cellulose (NFC) and polystyrene. The external NFC layer was functionalized with Cibacron Blue and the dynamic binding capacity of the column was measured by performing three chromatographic cycles, using bovine serum albumin (BSA) as target molecule. The second part of the thesis deals with Covid-19 pandemic related research activities. In early 2020, due to the pandemic outbreak, surgical face masks became an essential non-pharmaceutical intervention to limit the spread. To address the consequent shortage and to support the reconversion of the Italian industry, in late March 2020 a multidisciplinary group of the University of Bologna created the first Italian laboratory able to perform all the tests required for the evaluation and certification of surgical masks. More than 1200 tests were performed on about 350 prototypes, according to the standard EN 14683:2019. The results were analyzed to define the best material properties and masks composition for the production of masks with excellent efficiency. To optimize the usage of surgical masks and to reduce their environmental burden, the variation of their performance over time of usage were investigated as to determine the maximum lifetime.
