James City-area historical tornado activity is slightly below Pennsylvania state average. It is 37% smaller than the overall U.S. average. On 5/31/1985, a category F4 (max. wind speeds 207-260 mph) tornado 9.9 miles away from the James City place center killed 4 people and injured 40 people.
Maasai - Age-sets. Introduction. The basic Maasai political and social structure is their rigid system of age-sets (or age grades; strictly-speaking, an age-grade is a stage within the age-set). These apply primarily to men; women automatically become members of the age-set of their husbands. Under this system, groups of the same age (give or take five years or so) are initiated into adult life during the same period. The age-set thus formed is a permanent grouping, and lasts throughout the life of its members.
I am not talking about age and grade equivalent scores, as some have, but about the standard scores and percentiles compared with others at the same age and the same grade level. For a retained child, I. will run grade norms on math, which is very much tied to teaching certain skills at certain grade levels.he age/grade equivalent is simply that the child obtained the raw score corresponding to the average raw. score obtained by a group of children at the specified age/grade. Most tests lack a sufficient number of items at any specific age/grade level of difficulty due to their broad age/grade range of the test.
