group dynamic assessment (g-da) grounded in vygotsky’s socio-cultural theory (sct) is believed to have the potential to provide a context for capturing a group of learners’ zone of proximal development (zpd) (poehner & lantolf, 2010; shabani, 2010). the present study aims at testing the applicability of g-da in identifying the mediational strategies offered by a mediator during his g-da int...

Glial cells form a network in the central nervous system to support neurons and interact with them. The glia consist essentially of astrocytes that help with the nutrition of neurons and react in some cases of injury, oligodendrocytes that produce myelin, and microglia that are derived from the haemopoietic system and are concerned with the immunological defense of the nervous system. Experimen...

Power moments of Jk(t, G) = 1 √ πG ∫ ∞ −∞ |ζ( 1 2 + it+ iu)|2ke−(u/G)2 du (t ≍ T, T ε ≤ G ≪ T ), where k is a natural number, are investigated. The results that are obtained are used to show how bounds for ∫ T 0 |ζ( 1 2 + it)|2k dt may be obtained.

The study aimed to apply the National Economic Indicator on data from a cross-sectional population-based study (nw =2,197) in the city of Ribeirão Preto, Southeastern Brazil, in 2006. Compared to Brazil, the indicator presented a concentration around the last five deciles and was similar to that of the municipality of São Paulo, also in Southeastern Brazil.
