Ce travail montre une étude sur l’oralité et l’interculturalité présentes dans l’ouvrage Le chercheur d’or, de J.-M. G. Le Clézio. Les sources des principaux mythes et légendes introduits dans le récit seront mis en évidence, afin de faire ressortir la façon par laquelle l’auteur propose un panorama culturel avec plusieurs faces, en mélangeant, d’une manière homogène, des éléments différents par rapport à ses origines. Ainsi, nous décrirons les éléments essentiels du récit pour que nous puissions comprendre comment Le Clézio transforme son texte en une mosaïque ethno-culturelle, dont l’aspect poliphonique a une grande importance pour que l’interculturalité proposée et l’unité du récit soient atteintes

Objective: To analyze the association between sleep quality and quality of life of nursing professionals according to their work schedules. Methods: A prospective, cross-sectional, observational study was conducted between January and December 2010, with 264 nursing professionals, drawn from 989 subjects at Botucatu General Hospital and stratified by professional category. The Pittsburg Sleep Quality Index and the WHOQOL-bref were administered to evaluate sleep quality and quality of life, respectively. Self-reported demographic data were collected with a standard form. Continuous variables were reported as means and standard deviations, and categorical variables were expressed as proportions. Associations were evaluated using Spearman's correlation coefficient. The association of night-shift work and gender with sleep disturbance was evaluated by logistic regression analysis using a model adjusted for age and considering sleep disturbance the dependent variable. The level of significance was p < 0.05. Results: Night-shift work was associated with severe worsening of at least one component of sleep quality in the model adjusted for age (OR = 1.91; 95% CI 1.04; 3.50; p = 0.036). Female gender was associated with sleep disturbance (OR = 3.40; 95% CI 1.37; 8.40; p = 0.008). Quality of life and quality of sleep were closely correlated (R = -0.56; p < 0.001). Conclusions: Characteristics of the nursing profession affect sleep quality and quality of life, and these two variables are associated.

All Latin students eventually have a problem with qui. To solve it, they need a third qui in their quiver. The problem shows up when they advance into third year, transitioning from Caesar to Roman Comedy, or to the poets. The familiar “who” often leads to nonsense, and they are at a loss. There are three qui’s: the relative pronoun, the interrogative adjective, and the old ablative instrumental, e.g. 1. qui dixit, who spoke 2. qui vir, which man 3. illud qui, that thing by means of which It is the third that causes problems. So this article addresses the question “how do you tell qui from qui ?” There are six main ways to tell when to say “how,” “whereby,” or “the way” for qui: 1. The whereby/how qui is usually interrogative. 2. It is often marked further by being paired with a following quia: qui? quia “How . . . ? Because . . .” 3. The most frequent associated idea is of knowing, with a form of scire or gnoscere: qui scis, qui noveris? “How do you know?” 4. Qui followed immediately by an adverb or comparative is whereby/how/the way: qui minus quam . . . “How less than . . .” 5. The obvious noun antecedent is not a person, but a tool: machinas qui, “tools to __ with” (“with which to__”). 6. If the context is of giving or seeking, qui is instrumental, “how,” “a way,” “the means, “ e.g. da mi qui comparem “Give me the means to buy . . .” There is no antecedent.
