Catching Fish and Avoiding Sharks

Catching Fish and Avoiding Sharks

Although researchers agree that the first 5 years of life are critical for children’s developing executive functions (EFs), further advances are hindered by a lack of consensus on the design and selection of developmentally appropriate EF tasks for young children. Given this debate, well-established adult measures of EF routinely have been adapted for young children. Given young children’s comp...

Catching Fish and Avoiding Sharks: Investigating Factors That Influence Developmentally Appropriate Measurement of Preschoolers' Inhibitory Control.

Anglers’ Probabilities of Catching Record-Size Fish

—Most state fishery management agencies publish lists of the largest (e.g., 10, 25, and 50) specimens of each species captured by anglers. We fitted normal distributions for smallmouth bass Micropterus dolomieu and striped bass Morone saxatilis and a mixture of two normal distributions of largemouth bass Micropterus salmoides to the length of time that individual fish had been present on lists ...

Mathematical model of echolocation of fish-catching bats

The ability of bats to prey on the insects and catch fish on thewing bymeans of echolocation is remarkable, since the acoustic power transmission through air–water interface is very small. A mathematical model describing the way in which a bat can detect fish under the water surface is suggested in this article. The problem of scattering of the spherical acoustical wave from the water with the ...
