Dans sa remarquable contribution à La Cuisine du sacrifice (1979), Jean-Pierre Vernant a donné une analyse du sacrifice grec qui a durablement marqué la recherche. La commensalité impliquée par l’abattage et le partage d’un animal domestique, de même que la définition du statut respectif des sacrifiants et des destinataires inhérente à ce partage sont des passages désormais obligés de toute réflexion sur l’opération sacrificielle. C’est néanmoins le propre des étapes marquantes de la recherche de susciter la réflexion et d’inviter à un approfondissement. Dès lors, cet article met l’accent sur un aspect de ladite opération quelque peu négligé par l’article de 1979 : les vecteurs de la communication entre des sphères séparées. En repartant de l’analyse du lexique sacrificiel engageant la notion grecque d’agos, on propose quelques pistes pour réévaluer la manière grecque de penser le contact avec les dieux. [less ▲]

BACKGROUND: We have previously shown that short sessions of whole body vibration (WBV) were not able to significantly improve fall risk among nursing home residents but some trends towards an improvement of motor capacity were observed. OBJECTIVE: The objective of the present study was to evaluate the impact of 6-month training by WBV on functional and motor abilities among nursing home residents observed over a 12-month period. METHODS: Patients were randomized into two groups: the WBV group which received three training sessions every week composed of five series of 15 s of vibration at 30 Hz intensity for a period of 6 months and a control group with normal daily life. The impact of this training on the risk of falls was assessed blindly after 6 and 12 months by the Tinetti Test, the "Timed Up and Go" test and a quantitative evaluation of a 10-s walk performed with a tri-axial accelerometer. The occurrence of falls was also observed. RESULTS: 62 elderly healthy volunteers, (47 women and 15 men, mean age 83.2 +/- 7.9 years) were included in this study. There was no significant difference between the two groups regarding the Tinetti test (p = 0.75), the "Timed Up and Go" test (p = 0.19) and the Locometrix(R) test, except for the step length, measured by dual task (p < 0.01). No significant inter-group difference in the frequency of falls was observed during the 12 months of research. A total of 42 falls were recorded during the first 6 months of experimentation: 24 falls in the treated group and 18 in the control group (p = 0.60). During the next 6 months, 19 falls occurred: 8 falls in the treated group and 11 in the control group (p = 0.52). CONCLUSION: This study failed to establish the effectiveness of low doses of WBV, under the conditions used in our study, on functional and motor abilities of institutionalized elderly patients. However, given the positive results of other studies, further investigations, with modified therapeutic protocols, seem necessary to clarify the effects of WBV in the elderly. [less ▲]

Besides being known for population overcrowding, prison staff strikes, and prisoner suicides or escapes, which are frequently reported by the press, prison might also be a place for rare innovative projects. One such project can be seen in a penitentiary policy initiated in Belgium in 2000 aimed at re-shaping the culture of detention towards a culture of ‘restorative justice’. What can be said of this attempt at introducing the concepts of victim, restoration, responsibilization, sensitizing and awareness within prison walls? The present article proposes an illustrative and interpretive account of this prison policy. Rather than restoring the broken victim-offender relationship, its implementation has something to do with detainees working on their ‘self’. [less ▲]

The aphid–ant mutualistic relationships are not necessarily obligate for neither partners but evidence is that such interactions provide them strong advantages in terms of global fitness. While it is largely assumed that ants actively search for their mutualistic partners namely using volatile cues; whether winged aphids (i.e. aphids’ most mobile form) are able to select ant-frequented areas had not been investigated so far. Ant-frequented sites would indeed offer several advantages for these aphids including a lower predation pressure through ant presence and enhanced chances of establishing mutuaslistic interactions with neighbour ant colonies. In the field, aphid colonies are often observed in higher densities around ant nests, which is probably linked to a better survival ensured by ants’ services. Nevertheless, this could also result from a preferential establishment of winged aphids in ant-frequented areas. We tested this last hypothesis through different ethological assays and show that the facultative myrmecophilous black bean aphid, Aphis fabae L., does not orientate its search for a host plant preferentially towards ant-frequented plants. However our results suggest that ants reduce the number of winged aphids leaving the newly colonized plant. Thus, ants involved in facultative myrmecophilous interactions with aphids appear to contribute to structure aphid populations in the field by ensuring a better establishment and survival of newly established colonies rather than by inducing a deliberate plant selection by aphid partners based on the proximity of ant colonies.

A partir de l’analyse de récits d’expériences marquantes, à forte charge émotionnelle, rapportées par des enseignants débutants, des schémas d’intelligibilité de ces situations vécues ont été construits. Ceux-ci rendent compte des transformations identitaires et émotionnelles des enseignants débutants au travers des dynamiques transactionnelles de reconnaissance. Ces résultats ouvrent des perspectives pour la formation initiale des enseignants et l’accompagnement des enseignants débutants. Les schémas d’intelligibilité pourront être utilisés dans une démarche de réflexivité pour faciliter le décodage de situations professionnelles à forte charge émotionnelle vécues par l’enseignant et l’aider à donner sens à ses expériences [less ▲]

This paper presents a research on a specific type of unstiffened extended end-plate joint used to connect I-shaped beams to concrete-filled rectangular hollow section columns. The main idea is to use long bolts throughout the column to connect the beam end-plates, so avoiding intermediate connecting elements (e.g. a reverse U channel) or special bolts (e.g. blind bolts). However, the use of long bolts for beam-to-column con-nections is still rare in the construction and no design procedure exists in the Eurocodes; this justifies the pre-sent research. Firstly, a test program within a RFCS European project titled HSS-SERF “High Strength Steel in Seismic Resistant Building Frames”, 2009-2013 was performed. In this project, specimens subjected to sig-nificant bending moments (and shear) or to shear only was defined. Then, analytical developments based on the component approach and aimed at predicting the joint response have been carried out; their validity is demonstrated through comparisons with the tests. Finally, design guidelines have been provided. [less ▲]

The influence of substrate hydrophobicity and biomacromolecules (dextran, bovine serum albumin - BSA) adsorption on the cleanability of surfaces soiled by spraying aqueous suspensions of quartz particles (10 to 30 µm size), then dried, was investigated using glass and polystyrene as substrates. The cleanability was evaluated using radial flow cell (RFC). The surface composition was determined by X-ray photoelectron spectroscopy (XPS). The interpretation of XPS data allowed the complexity due to the ubiquitous presence of organic contaminants to be coped with, and the surface composition to be expressed in terms of both the amount of adlayer and the mass concentration of adlayer constituents. When soiled with a suspension of particles in water, glass was much less cleanable than polystyrene, which was attributed to its much lower water contact angle, in agreement with previous observations on starch soil. Dextran was easily desorbed and did not affect the cleanability. The presence of BSA at the interface strongly improved the cleanability of glass while the contact angle did not change appreciably. In contrast, soiling polystyrene with quartz particles suspended in a BSA solution instead of water did not change markedly the cleanability, while the contact angle was much lower and the aggregates of soiling particles were more flat. These observations are explained by the major role of capillary forces developed upon drying, which influence the closeness of the contact between the soiling particles and the substrate and, thereby, the adherence of particles. The capillary forces are proportional to the liquid surface tension and depend in a more complex way on contact angles of the particles and of the substrate. The dependence of cleanability on capillary forces, and in particular on the liquid surface tension, is predominant as compared with its dependence on the size and shape of the soiling aggregates, which influence the efficiency of shear forces exerted by the flowing water upon cleaning.

The inability to vocally match a pitch can be caused by poor pitch perception or by poor vocal-motor control. Although previous studies have tried to examine the relationship between pitch perception and vocal production, they have failed to control for the timbre of the target to be matched. In the present study, we compare pitch matching accuracy with an unfamiliar instrument (the slider) and with the voice, designed such that the slider plays back recordings of the participant’s own voice. We also measured pitch accuracy in singing a familiar melody (“Happy Birthday”) to assess the relationship between single pitch matching tasks and melodic singing. Our results showed that participants (all nonmusicians) were significantly better at matching recordings of their own voices with the slider than with their voice, indicating that vocal-motor control is an important limiting factor on singing ability. We also found significant correlations between the ability to sing a melody in tune and vocal pitch matching, but not instrumental pitch matching. Better melodic singers also tended to have higher quality voices (as measured by acoustic variables). These results provide important evidence about the ultimate causes of poor singing ability, and demonstrate that single pitch matching tasks can be useful in measuring general singing abilities.

This article emphasizes the impacts of international migration on ageing processes and norms within transnational families, and, specifically, analyses the roles of the zero generation, defined as the parents of first-generation migrants (Nedelcu 2009), both as non-migrant counterparts to their children abroad and as ageing migrants themselves. Transnational caregiving research has demonstrated that for many migrants and their families care arrangements must be negotiated across national borders, yet the agency of transnational older adults has been largely neglected. Based on qualitative fieldwork conducted from 2011 to 2013 in Liège, Belgium and Oujda, Morocco, the present article examines the circulation of care between Moroccan adult migrants and their ageing ascendants. This article exposes the duality of migrants’ ascendants as care givers and recipients, asserting firstly, that receiving care is not synonymous with passivity, and that, secondly, migrants’ ascendants are also the initiators of transnational practices. In both roles, this article underlines mobility as a strategy used by migrants’ parents to maintain family solidarity across national borders, but that this care mobility is limited by macro-level migration policies, here exemplified by the Belgian migration regime.

The different steps of the foraging process of wireworms (Coleoptera: Elateridae) would be better understood if accurate and holistic information regarding the role of plant-produced chemicals constituting their environment were available. Volatile organic compounds (VOC) play important roles in the interactions between plants and insects in many ecosystems, whether they take place aboveground or belowground. The roles of VOC are still relatively unknown for wireworms, and deserve attention. Here, we performed three experimentations with barley roots as baits. In the two first, we assessed the effect of chopped roots and fungus infected roots on the orientation of wireworms. In the third experiment, the larvae were confronted to both healthy and fungus infected roots. We discuss the results in terms of suitability of the olfactometers we designed for the investigation of olfaction in wireworms, and we provide suggestions to improve their use. [less ▲]

To date, magnetic shields utilizing high-temperature superconductor materials mostly comprise bulk materials, usually shaped into a cylinder and then heat treated. We analyze the potential of thin-film technology, whereby a layer of superconductor is deposited on a substrate, to fabricate magnetic shields. Films deposited on a curved surface are inevitably granular, leading to reduced critical current density compared with crystalline films. This limits the maximum field that can be screened. Granular films also have an enhanced penetration depth compared with the bulk value, which determines the maximum possible screening at applied fields below the maximum.We demonstrate the utility of a mutual inductancemeasurement to evaluate small flat test samples of a granular film for their potential as a shielding material in a more complex geometry. Thismeasurement predicts both themaximum magnetic field that can be screened and the residual leakage at fields below the maximum. The tested film was produced by the Electrophoretic deposition of YBCO on a silver substrate. The maximum screening field was comparable with that obtained for a similar film on a cylindrical substrate. We also show comparable results from a crystalline YBCO film. [less ▲]
