Nijhout [1] divided phenotypic plasticity into two broad types- a basal form of absence of homeostatic mechanisms to buffer an organism's phenotype against environmental variation and a derived form that adapts an organism to particular environments.
To isolate migration's role as a unique form of absence, this stage of analysis excludes those children whose parents are away and divorced (N = 207 in Moldova; N = 175 in Georgia).
Call it a case of absence as a form of presence.
Such alternate reproductive strategies are a form of pre-adaptation in the absence of mates or pollinators that also generates a fitness advantage in novel ecosystems where natural enemies are scarce.
And political speech can take the form of absence rather than presence: earlier today, Stevie Wonder announced a performance boycott of Florida and any other state with a "stand your ground" law.
In the end, however, the most chilling subject participation at the festival took the form of absence.
In robotics and artificial intelligence, researchers found that by providing robots with biological perceptuomotor systems able to perceive, process, and encode aspects of the external world they could create a form of intelligence that emerged in the absence of rich explicit internal representations of the environment (Brooks, 1991; Kirsh, 1991).
The different outcomes associated with migration, divorce, or both are likely explained by specifics in these forms of absence.
(ii) Function of attendance: the system can record the attendance information of every miner and calculate the statistical information of all miners, and it can establish all kinds of report forms such as forms of working time, forms of monthly attendance, forms of overtime work, and forms of absence.
For example it is possible that some forms of absence might be unplanned, involuntary and unsanctioned.
