Attitudes of Undergraduate Nursing Students towards Patient Safety: A Quasi-Experimental Study
2021
Improving nursing students’ attitudes towards patient safety is a current and relevant topic. This study aims to evaluate the effectiveness of an educational intervention based on critical incident and root cause analysis (RCA) techniques regarding attitudes towards patient safety in nursing students. A quasi-experimental before and after study was developed between January 2018 and December 2019 in a sample of 100 nursing students at Universitat Jaume I (Spain). The intervention was developed in two phases. Phase I was at university, where students applied the RCA technique in a real case. Phase II took place during clinical practice. Students used critical incidents to identify a risk sit…
Dispositif automatique de caractérisation et de prélèvement des eaux de drainage du site de Virey-le-Grand
2021
National audience; Le drainage a pour objectif d’évacuer rapidement l’excès d’eau de la partie supérieure du sol. Par conséquence il entraine des perturbations dans l’environnement notamment en favorisant la lixiviation d’intrants. Le dispositif de Virey-le-Grand, conçu dans les années 1970 pour étudier les différentes modalités de drainage, a été ré-instrumenté et automatisé afin de travailler sur l’évaluation de l’impact des pratiques agricoles sur la qualité de l’eau. Cette ré-instrumentation associe des équipements robustes comme les augets basculants à de la technologie plus récente telle que les panneaux photovoltaïques et une centrale d’acquisition. L’évolution des technologies a per…
Spectroscopic Observations of the Delta Scorpii Binary during Its Recent Periastron Passage
2001
The bright star delta Sco has been considered a typical B0-type object for many years. Spectra of the star published prior to 1990 showed no evidence of emission, but only of short-term line profile variations attributed to nonradial pulsations. Speckle interferometric observations show that delta Sco is a binary system with a highly-eccentric orbit and a period of 10.6 years. Weak emission in the H-alpha line was detected in its spectrum for the first time during a periastron passage in 1990. Shortly before the next periastron passage in the summer of 2000, the binary entered a strong H-alpha emission and enhanced mass loss phase. We monitored the spectroscopic development of the Be outbur…
Long-term Additions of Organic Amendments in a Loire Valley Vineyard. I. Effects on Properties of a Calcareous Sandy Soil
2008
International audience; A long-term experiment (28 years) was conducted to Study the effects of various organic amendments oil physical, chemical, and biological properties of a sandy vineyard soil. Annual applications of either crushed pruned vine-wood (2 t/ha fresh wt), cattle manure (10 and 20 t/ha fresh wt.), or spent mushroom compost (8 and 16 t/ha fresh wt) were compared to all unamended treatment, In plots unamended for 28 years, total organic C (TOC) showed a slow and limited decrease (19%). For the highest rates of exogenous organic amendments, the increase in TOC reached a saturation Value after 20 years and carbon (C) sequestered after 28 years reached 30 Mg/ha. Final predicted T…

Sustainable viticulure in Brazil's context : a proposition
2015
The thesis involves the proposition of a framework for the sustainability of viticulture in Brazil using a territorial approach built from two exploratory studies in Brazilian wine regions of Campanha Gaúcha and Vale do São Francisco based on preliminary studies. Those studies involved technical visits in three countries (France, Italy and Spain) and frameworks’ observations in another five (South Africa, Australia, New Zealand, USA and Chile). The framework proposed is called BaccuS. It is structured on a matrix basis, with an axis corresponding to dimensions and other to guidelines, both in ascending order of complexity and development. There are eighteen topics that represent areas to ac…
Enantiomeric separation of chiral phenoxy acid herbicides by electrokinetic chromatography. Application to the determination of analyte-selector appa…
2001
The enantiomeric resolution of chiral phenoxy acid herbicides was performed by electrokinetic chromatography using a cyclodextrin as chiral pseudophase (CD-EKC). A systematic evaluation of several neutral and charged cyclodextrins was made. Among the cyclodextrins tested, (2-hydroxy)propyl beta-cyclodextrin (HP-beta-CD) was found to be the most appropriate for the enantioseparation of phenoxy acids. The influence of some experimental conditions, such as nature and pH of the background electrolyte, chiral selector concentration, and temperature, on the enantiomeric separation of phenoxy acids was also studied. The use of a 50 mM electrolyte solution in ammonium formate at pH 5 and a temperat…
Fast enantiomeric separation of uniconazole and diniconazole by electrokinetic chromatography using an anionic cyclodextrin: application to the deter…
2000
The enantiomeric resolution of the fungicides uniconazole and diniconazole was performed using electrokinetic chromatography with cyclodextrins as pseudostationary phase (CD-EKC). A systematic evaluation of several chiral selectors was made. The anionic derivative carboxymethylated-gamma-cyclodextrin (CM-gamma-CD) was found to be the most appropriate for the enantioseparation of fungicides among all cyclodextrins tested. The influence of some experimental conditions such as nature and buffer pH, chiral selector concentration, and temperature on the enantiomeric separation of the compounds studied was also investigated. The use of a 50 mM phosphate buffer (pH 6.5) containing 5 mM CM-gamma-CD…
El rol del modelo de las competencias en la reconfiguración meritocrática de las pautas de negociación salarial en empresas argentinas: continuidades…
2020
The development of new models of work organization and the complementary advance of flexible guidelines for the use of the labor force had as a correlate a profound change in techniques for the evaluation of workers. Thus, the typical model of Fordism, based on qualifications, was replaced by a different one based on competencies, whereby the strong relationship of the former was abandoned with the determination of the technical knowledge required for each job to move to a system which the priority is placed in the individual attitude. The consequent individualization of performance evaluations can lead to a possible loss of objectivity. In this article we develop a theoretical comparison b…
CHALLENGES AND SOLUTIONS OF TVET QUALITY ASSURANCE IN MONGOLIA
2020
Technical and vocational education and training (TVET) makes a significant contribution to economic competitiveness in a knowledge-based economy. The main challenge for vocational education and training is to meet the changing skill needs in the labour market. In order to balance labour market supply and demand by constantly diversifying TVET customer base, it is necessary to increase the key role played by vocational education and training in economic competitiveness and social inclusion. The considerable economic growth in Mongolia does not have a positive impact on the creation of new jobs and poverty reduction. This implies that the Mongolian education sector was unable to produce requi…
