the bubbles, which about exhausts the uses of bubbles. For 
a more adult example, consider the new phenomenon of 
vacation condominium time sharing: 
own ( Pj, <Ec January>, Fh, Uu) - oT 
would mean that the January owner (Pj) decides which users 
(U) can have habitation use (Fh) of the condominium (Ec), 
but only during the month of January. Note the restrictions 
on the uses of the condominium that Pj has control over. He 
cannot remodel it, or manufacture something there, or 
.estroy it. Also, the event he owns is defined in time. 
Other than January, he is not the owner. More generally, 
the rights vested by ownership tend to be limited rather 
than absolute, and need not entail control over all uses of 
an object or event with respect to all other agents (Hecht, 
1964).

developed, this one does highlight important characteristics 
of the concept. First of all, it is evident that ownership 
has a political quality , i.e. people controlling people. 
The primary relationship may not be between the owner and 
the object he owns, but between the owner and the
