Stemming from a doctoral research on the culinary practices of a group of Moroccan migrant women living in the north of Italy, this paper will focus on some narratives and habits concerning homemade food. This food was the result of the combination of hyper-local and transnational practices. In fact, preparing some food at home instead of buying it (bread, for example) was possible also thanks to the use of some ingredients that were bought in or coming from Morocco. The issue at stake was that of control: a control exerted at a hyper-local level (in one’s home) on procedures and at a transnational level (by personally knowing ingredients’ producers) on food elements. This combination let women prepare some representative food of their memory by using the traditional techniques learnt from their mothers and by excluding intermediations. Homemade food translated the reassuring utopia of keeping a link with a cultural belonging in spite of migration and of reducing the fear of being contaminated by the unknown products of the diversity. Some ethnographic data will be presented to show these dynamics, and they will be supported by the visual material collected through participant observation. [less ▲]

The notion of subjectivation is employed in the human and social sciences to define the dynamic and complex process of definition of the self. In this process, several factors interact, both rising from those which appear as inner needs and from cultural and social expectations. This occurs at different levels of the individual’s everyday life’s experience, one of which is the material one. At this level we find diets, which actively perform on corporeality meant as embodied self. The materiality of food habits and culinary practices is the site where the stratified definition of individual subjectivity take place and where cultural and social belongings are represented and negotiated. In order to support this statement, I will present the life history of the key informant of my doctoral research that was devoted to the culinary practices of a group of Moroccan women living in context of migration. The ethnographic data were collected during an eighteen months fieldwork conducted in Milan hinterland (Italy). Through participant observation and semi-structured interviews, I studied the way of eating of this woman and her family. Their diet was influenced by several factors, among which the most relevant one was the illness of one of the children, a young girl suffering from diabetes mellitus. The (micro)materiality of food choices made by her mother for her nourishment, played a crucial role in the definition of the girl’s body and of its representation. In fact, this woman negotiated her culinary practices, stemming from her embodied memory, with medical prescriptions and instruments in order to restore her child’s body to health and thus shaping it as socially acceptable. We see a double-direction movement involving food and the body: the incorporation of appropriate nourishment, assured by a strict measurement of food biological components, and the excorporation of some physiological functions delegated to external medical devices. Such dynamics are aimed at making the child’s body comply with those biomedical norms that control the individuals’ access to the “healthy collectivity”. The medical work on the body through food corresponds to the normalization of the cultural Other’s ways of eating, a process that seems to be fundamental to migrants’ integration in the host society. In this paper I will discuss these issues focusing on food practices as material culture which actively participates to the embodied process of subjectivation. I will support my presentation with visual materials. [less ▲]

Après avoir rappelé la différence entre perversion et fonctionnement psychologique pervers, nous proposerons une réflexion éthologique et écologique qui s’appuiera sur une pratique clinique en hôpital sécuritaire avec plusieurs patients au fonctionnement psychologique pervers. Dans un raisonnement où nous distinguons la signification d’un comportement de sa fonction, il apparaît que la maîtrise du territoire et du rang social sont des « facultés » perverses observables. Nous suggérons de concevoir le pervers comme un individu hyper-adapté à un environnement social (la prison, par exemple, mais pas seulement) dont il maîtrise remarquablement l’art de la relation et de la « territorialisation ». Nous mettrons également en évidence les grandes compétences perceptives de ces patients (notamment via une réponse au test de Rorschach) et la maitrise fulgurante de l’intuition relationnelle. L’ensemble de ces caractéristiques font du pervers un être très « compétent » d’un point de vue social. Ceci explique, lorsqu’ils s’expriment sur le terrain de la délinquance, la dimension « imparable » des actes criminels de ces individus. Au-delà de cette adaptation sociale performante et remarquable, surviennent néanmoins des moments paradoxaux où la « désadaptation » est complète. Ces « moments pervers », qui sont rencontrés dans la clinique avec ces patients et qui apparaissent inexplicables d’un point de vue éthologique et adaptatif, sont des phénomènes essentiels à mettre en évidence dans un processus d’évaluation diagnostique. Dès lors, le pervers doit être considéré comme un être dont le fonctionnement adaptatif est complexe, fluctuant sur un continuum entre hyper-adaptation (la plupart du temps) et inadaptation (s’exprimant sous la forme d’un hiatus). Précisons, en outre, que ce modèle adaptatif suggère clairement que le fonctionnement psychologique pervers n’est pas l’apanage du sujet délinquant sexuel, pas plus qu’il n’est celui du délinquant en règle général. Ce mode de fonctionnement est également à identifier dans de nombreuses situations sociales où l’exercice du pouvoir sur autrui est accepté voire encouragé. Pour conclure, nous insisterons sur le fait qu’un fonctionnement psychologique pervers est complexe à mettre en évidence, notamment parce qu’il demande du temps et le développement de qualités d’observation parfois difficilement opérationnelles dans certaines situations cliniques ou d’expertise. Pour pouvoir améliorer la connaissance de ce fonctionnement, cette entité demande une reconnaissance nosographique et diagnostique propre. Notre hypothèse d’une hyper-adaptation pourrait être éprouvée par des méthodes cognitives. Nous pensons, par exemple, à un dispositif proposant des tâches de résolutions de problèmes sans issue. Cependant, l’on peut se demander s’il est raisonnable d’envisager d’avoir une connaissance nomothétique de la personnalité perverse. Le nombre restreint de sujets « disponibles » pour une évaluation, leur logique insaisissable, leur tendance au refus de collaborer à une étude s’ils n’y trouvent pas avantage, etc. Ces arguments font que le sujet pervers échappe presque par principe aux méthodes de recherche conventionnelles. Cela ne veut évidemment pas dire que l’entité nosographique n’existe pas. Tout en connaissant le lourd tribut que peut représenter le fait d’apposer ce diagnostic à propos d’un sujet, nous estimons, néanmoins, qu’il est important de pouvoir le mettre en évidence lorsqu’il est présent (comme il est, par ailleurs, essentiel de se garder de le poser lorsqu’il est absent). Pour ce faire, la répétition et l’observation sont les seuls moyens de parvenir à objectiver ce type de fonctionnement en réduisant le risque d’identifier des faux positifs. La difficulté essentielle est et restera de parvenir à parler à écrire sur le pervers. Pointer une dynamique perverse et parvenir à la faire comprendre aux autres relève presque de l’impossible car, d’une certaine manière, le pervers est toujours dans le juste. Il n’a pas toujours une bonne excuse, il a toujours une bonne raison. Le principe pervers dépasse le dicible, la dynamique perverse est difficilement verbalisable. [less ▲]

Novel biocompatiblewater-soluble fluorescent micelleswithembedded perylene diimides (PDI) for intracellular applications have been prepared by self assembling of amphiphilic poly(vinyl alcohol)-b-poly(acrylonitrile) (PVA-b-PAN) copolymers in the presence of synthesized fluorophores. Amphiphilic PVA-b-PAN copolymers were obtained by selective hydrolysis of well-defined poly(vinyl acetate)-b-poly(acrylonitrile) (PVAc-b-PAN) copolymer. The preparation of the novel fluorescence micelles consisting of PVA hydrophilic shell and PAN hy- drophobic core with incorporated PDI fluorophores has been confirmed by DLS and TEManalysis. The cytotoxic- ity of the water-soluble fluorophores and their internalization into living cells depending on the micellar concentration have been tested. Itwas shown that they could successfully enter in living cellswithout destroying their morphology. The results obtained indicate that the novel water-soluble fluorescent micelles with embed- ded PDI fluorophores would be suitable for potential intracellular biomedical applications. [less ▲]

Directional room impulse responses (DRIRs) are composed of the sound contributions reaching a given location in the room from a well-defined direction in space. DRIRs can be useful in many applications, such as the evaluation of spatial room acoustics parameters, the detection of unwanted specular reflections or the 3D auralization of acoustic spaces. A spherical array containing 16 microphones has been realized to measure DRIRs. The logarithmic sinesweep technique is first applied to measure 16 impulse responses, one for each microphone. A spherical harmonics (SH) decomposition of the sound field is then obtained. Spatial aliasing, placement errors and the ‘white noise gain’ (WNG) have been analysed to define the useful bandwith of this measure, i.e. [250Hz – 4kHz]. The coefficients of the SH decomposition are then processed by some beamforming methods, in order to compute the DRIR in any direction around the spherical array. Time and 3D space representations can be generated. The results obtained in some rooms are illustrated in this paper: it is shown that the combination of the ‘delay-and-sum’ and ‘minimum-variance distorsionless response’ beamforming methods is particularly well suited for the analysis of DRIRs.

CIMEDE is a research project supported by the Region of Wallonia (Belgium). It stands for CIMEDE “Construction Industrielle de Maisons Evolutives, Durables et Economiques – industrial construction of evolutionary, sustainable and economic houses”. Since the materials envisaged for this project are timber and gypsum fibre board, it was necessary to design a constructive principle of lightweight timber frame constructions which meets the industrial, sustainable, evolutionary and economic requirements and also the requirements of the Belgian acoustic standard NBN S01-400-1. First of all, an inventory of constructive elements that are currently used in this type of construction (floors, walls and facades) is presented with their acoustic performances. Then, the laboratory measurements of some samples of floors, facades, interior walls and partition walls are described and discussed. On the basis of the measurement results, several solutions that best meet all criteria were retained and a mock-up was built with these constructive elements. Measurement results on this mock-up are also presented. The final solution for the floor, the partition wall, the interior wall and the facade which meets the acoustic requirements is finally described [less ▲]

Introduction In Belgium, sickness absence (SA) management implies complementary roles for family (FPs), social insurance (SIPs) and occupational physicians (OPs): FPs deliver sick notes, SIPs control SA benefits and OPs strive to adapt work environments to workers’ capacities. In practice however, there is little cooperation between the three physicians. This study aimed at identifying FP-OP-SIP cooperation channels in order to prevent long-term work disability. Methods The study involved two phases. (1) Using the nominal group technique, researchers from the three physician groups reached a consensus on 15 proposals to enhance inter-professional cooperation. (2) A Delphi study was conducted to validate these proposals: 61 experts representing professional groups of physicians (FP, SIP, OP), patients, government, employers and labor unions were asked to participate. A 18-items questionnaire (the 15 proposals + 3 open questions) was used in a 2-round Delphi study. Proposals were accepted if 80% of experts agreed. Results Participation rate was 77% in round 1 and 7 out of the 15 proposals were accepted. During round 2, participation rate was 94%; 2 of the remaining proposals reached agreement level. Public authorities were thus advised to invest in a) promotion of pre-return to work visit with the OP for sick-listed patients; b) a website with OPs contact data; c) joint guidelines for return to work guidance; d) joint training of the 3 physician groups; 5) safe electronic information exchange. Several proposals aiming at giving work-related information to FPs and SIPs did not reach agreement within the OPs expert group. OPs expressed concerns about their own workload and FPs or SIPs ability to understand and use those information. Discussion The need for inter-physician cooperation in disability management may exceed individual goodwill and should best be organised by public authorities. This study may be a first step in this process. [less ▲]

The literature on incident reporting generally describes Incident Reporting Systems (IRS) as technological tools aiming at improving safety in organizations by initiating a learning process from previous events, in order to prevent future incidents and accidents to occur. In this respect, many studies tend to focus on “barriers to reporting” in order to understand why people report (or not) incidents in the dedicated system. Alternatively, we proposed to study IRS as socio-technical artifacts which are embedded in a specific organizational culture and which are interpreted in different ways, illustrating what has been called “interpretive flexibility”. This communication is divided in two parts. First, relying on the Social Construction Of Technology (SCOT) framework, we present the different practices and meanings attributed to the reporting of incidents within the Belgian Nuclear Research Center (SCK•CEN). We link these to the various modes of learning that they enable. By doing so we participate to the opening-up of the research on Incident Reporting to alternative discourses, practices and meanings, unforeseen situations and uncertainties. Second, we present the preliminary results of creative workshops during which we initiated the participatory re-construction of the IRS within the Center, drawing on and extending the results of the “opening-up” phase. By doing so, we aim at contributing to a transparent realization of the reduction of complexity leading to an informed and collective decision on what could/should be the IRS of the Center. In conclusion, we propose a reflexive analysis of this process, and we formulate tentative future research directions. [less ▲]

Dans le présent article, nous présentons un parcours didactique visant à faire évoluer chez les élèves le concept de tangente, de leur connaissance antérieure de tangente à un cercle comme droite ne coupant la courbe qu’en un seul point jusqu’à une définition formalisée au sein d’un cours d’analyse. Nous montrons ainsi qu’une définition d’un objet mathématique n’est ni définitive, ni une simple description de l’objet. Le choix d’une définition au détriment d’une autre doit se faire à la lumière d’un projet plus global relatif à l’institution à laquelle elle appartient. [less ▲]

Module performance analysis is a well-established framework to assess changes in the health condition of the components of the engine gas-path. The primary material of the technique is the so-called vector of residuals, which are built as the difference between actual measurement taken in the gas-path and values predicted by means of an engine model. Obviously, the quality of the assessment of the engine condition depends strongly on the accuracy of the engine model. The present paper proposes a new approach for data-driven modelling of a fleet of engines of a given type. Such black-box models can be designed by operators such as airlines and thirdparty companies. The fleet-wide modelling process is formulated as a regression problem that provides a dedicated model for each engine in the fleet, while recognising that all engines are of the same type. The methodology is applied to a virtual fleet of engines generated within the ProDiMES environment. The set of models is assessed quantitatively through the coefficient of determination and is further used to perform anomaly detection. [less ▲]

Our essay focuses on some methodological issues concerning the semiotic analysis of practice. We will initially retrace the debate about the epistemological relationship between text and action, outlining the forms of enunciative praxis through different levels of pertinence analysis. Secondly, we propose the concept of ‘textualization’ as a mediation between text and action: textualizations (photographs, videos, notes) organize and represent practices which are in themselves ephemeral and elusive. Finally, we will consider the textual diagrammatization that we call ‘notation’: this analytical form of mediation between text and practice does not have the same status of in-vivo textualisations, but it works like an ex-post reconstruction which highlights the main gestures and exchanges while performing their grammaticalization. A more general aim of this essay is an enquiry into the legitimate objects of textual semiotics: what are the objects that it can analyze without betraying its principle of immanence, but also without being confined to it and, as a consequence, being unable to analyze practices and respond to topical questions on social issues and on the research in the human sciences?
