: Evolution of the examination at the end of college in sub-Saharan Africa
2004
The evolution of schooling in the developing systems in sub-Saharan Africa has brought a sizeable new population into the colleges. Unfortunately, the scarcity of resources and the need to pursue development of basic education prevents maintaining this population in the lycees. Thus the examination at the end of college becomes the focus of very stressful management of different currents and finds itself divided about aims which are not easy to reconcile. Original solutions can be found, as is the case in Mauretania, while the combination of better-known solutions may allow this examination to deal with these contradictions.

Revisiting the happy-productive worker thesis from a eudaimonic perspective: a systematic review
2021
The happy-productive worker thesis (HPWT) is considered the Holy Grail of management research, and it proposes caeteris paribus, happy workers show higher performance than their unhappy counterparts. However, eudaimonic well-being in the relationship between happiness and performance has been understudied. This paper provides a systematized review of empirical evidence in order to make a theoretical contribution to the happy-productive worker thesis from a eudaimonic perspective. Our review covers 105 quantitative studies and 188 relationships between eudaimonic well-being and performance. Results reveal that analyzing the eudaimonic facet of well-being provides general support for the HPWT…

Control of the mutagenicity of aromatic amines by protein kinases and phosphatases
1997
The role of protein kinase C and protein phosphatases was examined in the control of mutagenic metabolites of aromatic amines. Various metabolic activating systems derived from rat liver were treated with: 12-O-tetradecanoylphorbol-13-acetate (TPA), a protein kinase C modulator; okadaic acid (OA), a potent inhibitor of serine/threonine protein phosphatases (PP1 and PP2A); and ortho-vanadate (OV), an inhibitor of tyrosine phosphatases. TPA used over a wide concentration range (10−9–10−6 M) did not affect the bacterial mutagenicity of the aromatic amines and of the aromatic amide investigated, 2-aminoanthracene, 2-aminofluorene and 2-acetylaminofluorene (2AAF). At the molecular level, TPA did…
A preliminary approach to mineral intake in the Spanish diet established from analysis of the composition of university canteen menus
2012
Abstract The concentration of mineral elements in complete menus has in Spain been determined in order to establish the levels of essential and toxic elements and their contribution to the maximum recommended intake. Thirteen university canteen menus obtained from the Burjassot campus, in Valencia, were analysed to establish a first approach on mineral composition in the Spanish diet. The menus were composed of a mixture of cereals, meat, fish, vegetables, fruits and dairy products. Samples were crushed, homogenized and lyophilized, and 25 elements were determinated by inductively coupled plasma optical emission spectroscopy (ICP-OES) after digestion of samples in a microwave oven. Menu sam…
Determination of trace elements in gluten-free food for celiac people by ICP-MS
2014
Abstract This paper is the first analytical approach to the study of twenty heavy metals in the gluten-free foods for celiac people. Only the ICP-MS technique was used. One of the advantages about the use of ICP-MS for this characterization is the high sensitivity that improved the limits of quantification levels for some elements that are present at low quantities in some samples. The concentration values of As, Ba, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Sb, Se, Sn, V and Zn in seventeen gluten-free food samples are reported. The highest arsenic and molybdenum levels were measured in Rice noodle from China (0.088 and 0.47 mg kg − 1 , respectively). The highest concentrations of some metal…
The child diary as a research tool
2012
The aim of this article is to introduce the use of the child diary as a method in daily diary research. By describing the research process and detailing its structure, a child diary, a structured booklet in which children's parents and day-care personnel (N = 54 children) reported their observations, was evaluated. The participants reported the use of the diary to be an interesting but time-consuming experience. The main ethical challenges were related to power positions, confidentiality, consequences and motivation. With respect to adults’ observations of children's emotions, the results indicated that the child diary is valuable in providing information about individual differences and da…
Secondaire-supérieur
2008
Même si le lien entre le niveau de diplôme obtenu et la qualité de l'insertion professionnelle n'est pas parfait, posséder un diplôme de l'enseignement supérieur est un atout majeur à l'entrée sur le marché du travail. Cependant, alors qu'une des spécificités françaises du système d'enseignement supérieur est son caractère relativement différencié, son accès reste relativement typé socialement selon les distinctions qualitatives qu'il permet. Ces distinctions qualitatives, dans un contexte où l'accès aux différents niveaux d'enseignement s'est démocratisé, ne sont pas sans incidence sur l'insertion. Afin de comprendre les différences d'accès à l'enseignement supérieur et à ses types de curs…
Comportement des bacheliers : modèle de choix de disciplines
1979
The paper tries to take into account the choices taken by the high school graduates at the time of their immatriculation in higher education. The purpose is not a statistical description, but an attempt to test theoretical hypothesis of the individual behaviour. The analytical framework is based on the trade-off carried out by every student between the economical attractiveness of the different fields of education and professional careers which are linked on one hand, and the personal probability of success in every field on the other hand. In a first section, success models are estimated in various disciplines to get estimations of the objective chances of success for every student in ever…
