La publicación del informe PISA 2006 ha dado lugar a las mismas abundantes críticas y lamentaciones acerca del fracaso de nuestro sistema educativo -y, en particular, de la educación científica- que provocó el informe de 2003, a causa del lugar que ocupa España en el conjunto de países de la OCDE. No vamos a repetir aquí los argumentos que invalidan estas injustificadas lecturas de los resultados presentados en el informe: como mostrábamos en otro trabajo (Gil Pérez y Vilches, 2006), tienen la misma validez que sostener, cuando las notas medias de dos grupos de estudiantes en una determinada materia son, respectivamente, 5.5 y 4.9, que el primero ha funcionado mucho mejor que el segundo.
Do viscosity and wettability of fluoride varnishes affect their fluoride release?
2020
BACKGROUND: There are several brands of fluoride varnishes in the market, but the dynamics of fluoride release from each one might be different. The purpose of this study was to evaluate in vitro the release of fluorides by fluoride varnishes and to determine the correlation with viscosity and wettability. MATERIAL AND METHODS: Forty four enamel blocks 5x5 mm were randomly divided into 4 groups (n=11) ((Duraphat®, Clinpro™ White Varnish, Flúor Protector® and control). We applied 30 milligrams of fluoride varnish to each specimen. The specimens were immersed in a Calcium Phosphate solution at a pH= 6.0. We evaluated the release of fluoride, by using a selective fluoride electrode, during 6 w…
VALIDITY AND INVARIANCE OF MEASUREMENT OF THE SATISFACTION WITH LOVE LIFE SCALE IN OLDER ADULTS
2020
In recent years, interest in satisfaction with love life (SWLL) has increased. Empirical evidence demonstrated that SWLL favors subjective well-being, physical and mental health, marital quality and stability. In this regard, the study aimed to examine evidence based on the internal structure validity, reliability, and measurement invariance of the Peruvian version of the Satisfaction with Love Life Scale (SWLLS). The participants were 323 older adults recruited from the region of San Martin (Peru) with an average age of 68.73 years (SD = 7.17). The sample comprised of 49.5% women and 50.5% men. The results supported the one-dimensional model and adequate reliability of the SWLLS. A multi-g…

Crustal controls on light noble gas isotope variability along the andean volcanic arc
2021
This study combines new noble gas data from fluid inclusions in minerals from Sabancaya, Ubinas, and El Misti (CVZ, Peru) and Villarica (South Chile, SVZ) with a revised noble gas compilation in the Andes, to identify systematic along arc variations in helium isotope compositions. We find 3He/4He ratios varying from 8.8 RA (Colombia) to 7.4 RA (Ecuador) within the NVZ, and only as high as 6.4 RA in the CVZ (RA is the atmospheric 3He/4He ratio of 1.39 × 10–6). These distinct isotope compositions cannot be explained by variable radiogenic 4He production via slab fluid transport of U and Th in the mantle wedge, since both NVZ and CVZ share similar slab sediment inputs (Th/La ≈ 0.08–0.13). Inst…
Nutritional status, physical performance and disability in the elderly of the Peruvian Andes
2016
Background: Although nutritional status plays an important part in the physical performance and disability of older people, this relationship has been little studied in developing countries. Aims: A study on the effects of nutritional status on the physical performance and functional status of elderly people living in rural areas of the Peruvian Andes. Methods: The study concerned 222 people aged ≥65 years living in a rural area of the Peruvian Andes. The Mini-Nutritional Assessment (MNA) was used to classify participants as malnourished (MNA <= 17), at risk of malnutrition (MNA 18-23), or well-nourished (MNA>= 24). The short physical performance battery (SPPB) and six-minute walking …
Psychosocial risks at work and occupational health
2012
Los cambios que han ocurrido en las últimas décadas sobre los procesos laborales y el diseño del trabajo son de carácter sociodemográfico, económico, político, y tecnológico. Estos cambios han originado nuevos riesgos psicosociales en el trabajo que afectan a la salud y la calidad de vida laboral, pues incrementan los niveles de estrés de los trabajadores. El objetivo del estudio es presentar este tipo de riesgos, sus consecuencias, y algunas recomendaciones para promover la salud en el trabajo como estrategia para mejorar la salud pública de la población. El estudio se estructura en cinco puntos en los que: (1) se presenta el concepto de factores y riesgos psicosociales en el trabajo, (2) …

Les rémunérations des enseignants dans les pays de l'OCDE : évolution comparative
1985
référence interne : 85054; Cette étude comporte trois parties : une réflexion méthodologique, notamment sur les concepts de salaire et de coût salarial, une analyse détaillée des rémunérations et des conditions de travail des enseignants dans trois pays (France, États-Unis et Japon), une analyse plus globale de l'évolution du coût salarial des enseignants par niveaux dans les autres pays de l'OCDE incluant une comparaison avec d'autres professions, publiques ou privées.
