Aims and objectives: This study was designed to assess whether bilingual caregivers, compared with monolingual modify their nonverbal gestures match the increased communicative and/or cognitive-linguistic demands of language contexts – as would be predicted based on ‘Facilitative Strategy Hypothesis’.

Let $H$ be a directed acyclic graph (dag) that is not rooted star. It known there are constants $c=c(H)$ and $C=C(H)$ such the following holds for $D_n$, complete on $n$ vertices. There set of at most $C\log n$ subgraphs $D_n$ covers every $H$-copy while $c\log does cover all $H$-copies. Here this dichotomy considerably strengthened.
 ${\vec G}(n,p)$ denote probability space graphs with ve...
