Abstract. We describe the development of a non-hydrostatic version regional climate model RegCM4, called RegCM4-NH, for use at convection-permitting resolutions. The dynamical core Mesoscale Model MM5 is introduced in with some modifications to increase stability and applicability long-term simulations. Newly available explicit microphysics schemes are also described, three case studies intense...

The goal of this study was to evaluate the degree to which measuring joint attention an aspect of social attention, is meaningful for the learning and development of preschool children. Joint attention refers to the executive capacity to coordinate visual attention with another person. This pivotal skill begins to develop from 6 to 18 months of age and continues to be refined and coordinated th...

Forty-three mother-infant dyads were recruited to determine the relationship between both total equipment use and the use of individual pieces of equipment and infant motor development. At 8 months of age, total and individual equipment use was determined by parental survey and infant motor development was assessed using the Alberta Infant Motor Scale. Statistically significant correlations wer...
