Educational ergonomics is defined as that field of human factors/ergonomic science concerned with the interaction of educational performance and educational design. The premise of educational ergonomics is that student performance to a substantial degree is context specific---specialized in relation to specific design factors---and that ergonomic interventions directed at design improvements th...

Governments and institutions are facing the new demands of a rapidly changing society. Among many significant trends, some facts should be considered (Silverstein, 2006): (1) the increment of number and type of students; and (2) the limitations imposed by educational costs and course schedules. About the former, the need of a continuous update of knowledge and competences in an evolving work en...

BACKGROUND Parental educational expectations have been associated with children's educational attainment in a number of long-term longitudinal studies, but whether this relationship is causal has long been debated. The aims of this prospective study were twofold: 1) test whether low maternal educational expectations contributed to failure to graduate from high school; and 2) compare the results...

BACKGROUND In a context of population ageing, it is a priority for planning and prevention to understand the socioeconomic (SE) patterning of functional limitations and its consequences on healthcare needs. This paper aims at measuring the gender and SE inequalities in functional limitations and their age of onset among the Southern European elderly; then, we evaluate how functional status is l...

Thyroid nodules are common, occurring in almost two-thirds of some populations; among these only about 7% are malignant. The most important question with any new discovered thyroid nodule is, “is this malignant?” The main arbiter of malignancy or benignity remains fine needle aspiration and the mainstay of treatment surgery. But given the resources involved, doing an FNAC or surgery in every di...
