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 ▲]

Depuis une décennie, les découvertes de matériaux colorants se multiplient parmi les sites dont les occupations remontent au Paléolithique moyen et au Paléolithique supérieur ancien. L’intérêt qu’elles suscitent tient à ce qu’elles sont susceptibles de révéler des pratiques techniques diverses et complexes, mais il tient aussi à leur forte potentialité à traduire des pratiques symboliques du fait de leur pouvoir colorant intense et des couleurs exploitées : le rouge et le noir. C’est sur le gisement châtelperronien de la grotte du Renne à Arcy-sur-Cure (Yonne), fouillé de 1949 à 1963 par André Leroi-Gourhan, qu'environ 2000 matières colorantes découvertes ont conduit à échafauder des théories concernant leurs transformations et leurs utilisations qui méritaient d’être éprouvées. Il est supposé, depuis leur découverte, qu’elles ont fait l’objet d’un chauffage contrôlé qui visait à en modifier la couleur, le chauffage permettant de transformer les matières colorantes jaunes (hydroxydes de fer) en orangé, en rouge et en violacé (oxydes de fer). De cette hypothèse découle la théorie selon laquelle les Néandertaliens ont exploité les matières colorantes en tant que pigment pour des réalisations symboliques, voire d’ordre esthétique, ce qui n’a pas encore pu être prouvé. La présente étude, fondée sur le croisement des données issues des analyses de la nature physico-chimique et pétrographique des assemblages de matières colorantes, mais aussi sur leur intégration dans le gisement, en association avec des structures d’habitat dont la conservation est exceptionnelle, et sur une série d’expérimentations visant à caractériser les poudres obtenues par différents moyens a permis de définir les choix techniques qui ont présidé à l’approvisionnement en matières colorantes dans tous les niveaux d’occupation châtelperroniens de la grotte du Renne. Il a ainsi été possible de démontrer qu’aucune des matières colorantes, rouges ou noires, n’a fait l’objet d’un chauffage préalablement à son utilisation, bien au contraire de ce qui avait été supposé jusqu’ici. Ces matières colorantes ont fait l’objet d’un approvisionnement raisonné auprès de formations géologiques affleurant ponctuellement. L’exploitation de ces gîtes de matières premières colorantes a été la même durant toute la séquence châtelperronienne et s’est orientée préférentiellement vers des matériaux que l’on peut aisément réduire en poudre. L’assemblage des matières colorantes de la grotte du Renne révèle à la fois une permanence des pratiques techniques et culturelles qui ont trait à l’emploi de matières colorantes et un profond ancrage des connaissances et de la compréhension des multiples propriétés et qualités de ces matériaux intensément mises à profit dans des activités diverses, domestiques, artisanales et manifestement aussi d’ordre symbolique, de telle sorte que le gisement châtelperronien était tout de rouge et noir.

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.

This study investigates the impact job satisfaction, job involvement, organizational commitment and transfer climate on the training transfer process. Training transfer refers to the application of the new learning and to performance at work. A two-time data collection was implemented among employees of a public health insurance company who attended professional training programs (N=118). Data analysis revealed that (1) job involvement negatively influenced transfer; (2) peer support positively influenced transfer; (3) openness to change had a negative relationship with transfer; and (4) these three predictors have an indirect effect on performance at work.

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.

Context There is growing evidence that vitamin D plays a role on several tissues including skeletal muscle. Objective To summarize with a meta-analyse the effects of vitamin D supplementation on muscle function. Data sources A systematic research of randomized controlled trials, performed between 1966 and January 2014 has been conducted on Medline, Cochrane Database of Systematics Reviews, Cochrane Central Register of Controlled and completed by a manual review of the literature and congressional abstracts. Study selection All forms and doses of vitamin D supplementation, with or without calcium supplementation, compared with placebo or control were included. Out of the 225 potentially relevant articles, 30 randomized controlled trials involving 5615 individuals (mean age: 61.1 years) met the inclusion criteria. Data extraction Data were extracted by two independent reviewers. Data synthesis Results revealed a small but significant positive effect of vitamin D supplementation on global muscle strength with a standardized mean difference (SMD) of 0.17 (p=0.02). No significant effect was found on muscle mass (SMD 0.058; p=0.52) or muscle power (SMD 0.057; p=0.657). Results on muscle strength were significantly more important with people who presented a 25-hydroxyvitamin D level <30 nmol/L. Supplementation seems also more effective on people aged 65 years or older compared to younger subjects (SMD 0.25; 95% CI 0.01 to 0.48 versus SMD 0.03; 95% CI -0.08 to 0.14). Conclusions Vitamin D supplementation has a small positive impact on muscle strength but additional studies are needed to define optimal treatment modalities, including dose, mode of administration and duration.

Jatropha curcas oil has an insecticidal activity harnessed by the farmers in Niger. In this study, we compared the insecticidal activity of two batches of oil conserved during 70 days, one exposed to light and the other kept in the dark. The insecticidal efficacy was evaluated in a field with three concentrations (5, 10 and 15%) trial on the main pests of Cowpea (Vigna unguiculata (L.) Walp) and in a laboratory test on Megalurothrips sjostedti Trybon (Thysanoptera: Thripidae) with different concentrations of crude oil (50; 100; 150 and 200 µl). No difference in insecticidal effect was found between the two modes of oil conservation, both in the laboratory and in the field. In the field, regardless of the mode of conservation, the concentrations of 10% of J. curcas oil enables a reduction of over than 80% of thrips, aphids, and bugs compared to the control. Its increased seeds yield more than 50%. The concentration of 15% gives an insecticidal effect comparable to that of the reference treatment (deltaméthrine) but induces phytotoxicity symptoms on the leaves of Cowpea. [less ▲]

Ichthyosaurs rapidly diversified and colonised a wide range of ecological niches during the Early and Middle Triassic period, but experienced a major decline in diversity near the end of the Triassic. Timing and causes of this demise and the subsequent rapid radiation of the diverse, but less disparate, parvipelvian ichthyosaurs are still unknown, notably because of inadequate sampling in strata of latest Triassic age. Here, we describe an exceptionally large radius from Lower Jurassic deposits at Penarth near Cardiff, South Wales (UK) the morphology of which places it within the giant Triassic shastasaurids. A tentative total body size estimate, based on a regression analysis of various complete ichthyosaur skeletons, yields a value of 12-15 m. The specimen is substantially younger than any previously reported last known occurrences of shastasaurids and implies a Lazarus range in the lowermost Jurassic for this ichthyosaur morphotype.
