BACKGROUND Inequality in life expectancy (ILE) is defined as inequality in the distribution of expected span of life-based on data from survival tables estimated using the Atkinson inequality index. ILE can be influenced by socio-ecological indicators including the Gini coefficient, secondary education, output per worker, and old age pension. This study examined the effects on ILE from a social...

Studies have shown that videoconferences are an effective medium for facilitating communication between parties who are separated by distance. Furthermore, studies reveal that videoconferences are effective when used for distance learning, particularly when learners are engaged in complex collaborative learning tasks. However, as in face-to-face communication, learners benefit most when they re...

An inverse association between education and fertility in women has been found in many societies but the causes of this association remain inadequately understood. We investigated whether observed and unobserved family-background characteristics explained educational differences in lifetime fertility among 35,212 Finnish women born in 1940-50. Poisson and logistic regression models, adjusted fo...

We chronicle the use of acknowledgements in twentieth century scholarship by analyzing and classifying more than 4,500 specimens covering a 100-year period.

We demonstrate that the acknowledgment has gradually established itself as a con...

Fluid collaboration occurs when participants establish the pace of ensemble activity mutually, with their moves flexibly adjusted and respon...

METHODS This study analyses the association of two indicators of socio-economic position, education and income, with different measures of social networks...
