si le point final du chemin w a pour coordonnées (i(w), j(w)). Les chemins qu’on va considérer sont confinés dans l’intersection d’un certain nombre de demiplans rationnels, c’est-à-dire d’équation ai+ bj + c ≥ 0, pour a, b, c des rationnels non tous nuls. De telles contraintes apparaissent naturellement lorsque les chemins codent des familles d’objets combinatoires (arbres, cartes...), ou décr...

The bacterial population of water samples from the sea, lakes or other sources usually increases during storage. While several different factors may be operative (Prescott and Winslow, 1931), it is noteworthy that the magnitude of the increase is often related to the size of the receptacle in which the water is stored. For example, Whipple (1901) found that the bacterial population of water, wh...

Young people develop as “the sum of past experiences,” and data on their time use are one means of quantifying those experiences. U.S. children and adolescents spend dramatically less time than in the agrarian past in household and incomegenerating labor. Because such labor is usually repetitive and unchallenging, this reduction has probably not deprived youths of crucial developmental experien...

[1] Using high resolution simulations of eight welldocumented cloud cases in different climate regimes, this study investigated the statistical distributions of dynamic and thermodynamic variables in the cloud layer and examined various assumptions used by the current statistical cloud schemes. It is found that dynamic and thermodynamic variables skew differently in the cloud layer of shallow c...

The alerts issued by regulatory agencies on the potential cardiac toxicity of citalopram and escitalopram have caused alarm among clinicians. A review of the data concerning this topic shows that the alarm should be limited to patients with a history of syncope or poisoning. As a precautionary measure, an electrocardiogram should be performed on elderly patients.

What events do employees recall or anticipate when they think of past or future unfair treatment at work? We propose that an employee’s temporal perspective can change the salience of different types of injustice through its effect on cognitions about employment. Study 1 used a survey in which employee temporal focus was measured as an individual difference. Whereas greater levels of future foc...
