Schaie (1986) pointed out that this is because we tend to deï¬ne each variable in terms of. calendar time, and proposed designs for unlinking calendar time from the variables in. order to get at the independent effects of them (e.g., deï¬ning cohort more broadly than. time of birth) (see Chapter 2, this volume).
The Georgia Aquarium in Atlanta is the largest aquarium in the world housing more than 100,000 sea creatures. Funded mostly by a $250 million donation from Home Depot co-founder Bernie Marcus, the aquarium opened in November 2005. The Georgia Aquarium is the only institution outside of Asia to house whale sharks.
The main Aquarium tank measures 51m in length, 20m in depth and 11m in height. The Guinness World Record-winning acrylic panel in front of the tank offers free viewing for public from all three levels of the Dubai Mall. The 48m walk-through Tunnel offers 270-degree views from 11m below the surface of the tank. The aquarium has the largest collection of Sand Tiger Sharks in the world.
