Photosynthetic Characteristics and Estimated Growth Rates Indicate Grazing Is the Proximate Control of Primary Production in the Equatorial Pacific

Creator:

Cullen, John J., Lewis, Marlon R., Davis, Curtiss O., and Barber, Richard T.

Abstract:

Macronutrients persist in the surface layer of the equatorial Pacific Ocean because the production of phytoplankton is limited; the nature of this limitation has yet to be resolved. Measurements of photosynthesis as a function of irradiance (P-I) provide information on the control of primary productivity, a question of great biogeochemical...

Predictors of early growth in academic achievement : the head-toes-knees-shoulders task

Creator:

McClelland, Megan M., Cameron, Claire E., Duncan, Robert, Bowles, Ryan P., Acock, Alan C., Miao, Alicia, and Pratt, Megan E.

Abstract:

Children’s behavioral self-regulation and executive function (EF; including attentional or cognitive flexibility, working memory, and inhibitory control) are strong predictors of academic achievement. The present study examined the psychometric properties of a measure of behavioral self-regulation called the Head-Toes-Knees-Shoulders (HTKS) by assessing construct validity, including relations to EF measures, and...
