Recent research suggests that sleepiness and mind-wandering—the experience of thoughts that are both stimulus-independent and task-unrelated—frequently co-occur and are both associated with poorer cognitive functioning. Whether these two phenomena have distinguishable effects on task performance remains unknown, however. To investigate this question, we employed the online experience sampling of mind-wandering episodes and subjective sleepiness during a laboratory task (the Sustained Attention to Response Task; SART), and also assessed mind-wandering frequency and sleep-related disturbances in daily life using self-report questionnaires. The results revealed that the tendency to experience mind-wandering episodes during the SART and daily life was associated with higher levels of daytime sleepiness and sleep-related disturbances. Importantly, however, mind-wandering and sleepiness were independent predictors of SART performance at both the within- and between-individuals levels. These findings demonstrate that, although mind-wandering and sleepiness frequently co-occur, these two phenomena have distinguishable and additive effects on task performance. [less ▲]

Figure fascinante dont le cinéma s’est largement emparé, le monstre a majoritairement été envisagé en tant que motif par l’abondante littérature consacrée à cet objet. La monstruosité cinématographique n’en est pas pour autant strictement liée à la représentation du monstre. Par un glissement, un passage de Freaks (Tod Browning, 1932) à Decasia (Bill Morrison, 2002), cet article envisage la question de la monstruosité en tant que forme. [less ▲]

This conference explores the way in which Belgian law deals with situations where labour law engages with the right to freedom of religion and belief and the right not to be discriminated on grounds of religion. It starts with the Belgian regime of religious freedom, protection against discrimination and valid reasons for termination of employment. It then considers specific areas of those regimes in Belgian labour relations, such as the work schedule accommodation, the refusal to perform work, clothing and religious symbols in the workplace, and the work in an ethos organization. It relates mainly to Belgian case law but also to the case law of the European courts [less ▲]

A performant method for the simultaneous quantification of daidzein, genistein, formononetin and biochanin A in forages using an UPLC®-MS/MS was developed and fully validated. The ultrasound-assisted extraction and enzymatic hydrolysis used in the sample preparation step were optimized using the Box-Behnken experimental design. The optimal extraction conditions used for a representative mix of forage plants were 80°C, 10 min and 55% methanol, and for hydrolysis they were 20°C, 18 h and pH=6. The chromatographic separation was achieved using an Acquity® UPLC® HSS T3 column, with a water/methanol linear gradient containing 0.01% of formic acid at a 0.55 mL min-1 flow rate. The four isoflavones were detected by ESI mass spectrometry in positive ion MRM mode. The method allows high throughput analyses of samples and showed an adequate linear regression model for all isoflavones over a range from 5 to 125 ng mL-1. There was good intra- and inter-day precision (≤ 8.2% and ≤ 7.6%) and accuracy (≤ 11.4% and ≤ 7.1%). The recovery rates were in an acceptable range of 70-120%, except for biochanin A, where the rate was about 50%. Good method repeatability was also observed, and there was no matrix effect or carry-over problem. The sample extracts were stable for at least 6 days of storage at -21°C and 6°C. The method proved to be sensitive, precise and accurate for discriminating a wide variety of forages likely to be grazed by ruminants according to their isoflavone content and to observe the impact storage process on isoflavone content in forages.

Cette publication collective sur la notion de médiation est issue du constat suivant : dans le champ théorique comme dans le champ des pratiques, la médiation s’est aujourd’hui imposée, soit comme outil d’analyse des processus de communication, soit comme outil apte à soigner/traiter/améliorer les relations entre pairs, ou entre individus et institutions. Or la médiation reste un concept « instable », aussi bien dans la théorie, où elle est investie de toutes parts, que dans les pratiques, où elle ne répond pas à un référent unique. Ce recours aux pratiques et à la notion de médiation dans tous les domaines de la vie sociale , et ce alors même que cette notion n’est pas fondée, doit être interrogé comme tel dans un cadre scientifique et politique . Par l’examen croisé des usages de la notion dans différents champs de recherche et de ses usages dans des pratiques dites « de médiation », l’ouvrage entend présenter une approche critique et problématisée de la notion de médiation. A partir d’un corpus, d’enquêtes ou d’analyses de processus de médiation, les différents chapitres de l’ouvrage examinent les enjeux (scientifiques, théoriques, politiques ou idéologiques) auxquels l’usage du terme a répondu et répond aujourd’hui dans différents champs de recherches (sociologie, sciences de la communication, traduction, anthropologie) et de pratiques (médiation animale, scolaire, culturelle).

We consider the multi-trip vehicle routing problem, in which each vehicle can perform several routes during the same working shift to serve a set of customers. The problem arises when customers are close to each other or when their demands are large. A common approach consists of solving this problem by combining vehicle routing heuristics with bin packing routines in order to assign routes to vehicles. We compare this approach with a heuristic that makes use of specific operators designed to tackle the routing and the assignment aspects of the problem simultaneously. Two large neighborhood search heuristics are proposed to perform the comparison. We provide insights into the configuration of the proposed algorithms by analyzing the behavior of several of their components. In particular, we question the impact of the roulette wheel mechanism. We also observe that guiding the search with an objective function designed for the multi-trip case is crucial even when exploring the solution space of the vehicle routing problem. We provide several best known solutions for benchmark instances. [less ▲]
