58) As with disability or gender, this supposed "accommodation" can appear unjustified because the "different" functioning of sexual orientation appears to involve contested individual, cultural, and moral choices rather than simply biological constraint.
We will consider the biological constraint of fertility and its implications in the last part of this section.
According to Jaenisch (in a personal communication with the author following the hearing), faulty reprogramming does not create the same difficulties in differentiated cells derived from stem cells because in stem cell research (1) only cell lines, not whole organisms, are created, so that there is less of a biological constraint to activate their developmental program, and (2) appropriate stem cells can be selected for use from those in culture, in contrast to reproductive cloning, where little nor no selection is possible.
This pattern stems from a universal biological constraint, the researchers argue.
Thus, the diagram can be said to simplify--for the sake of illustration--a progression from biological constraints to culture that is, in fact, anything but linear.
Instead of being limited and held back by genetic or biological constraints that we have been programmed to believe, we actually can create and develop the health we desire by the thoughts that we think.
By conducting experiments across several populations (human adults and infants) and species (human and nonhuman animals), and using a wide array of experimental techniques, the present proposal hopes to shed some light on the origins of shared biological constraints that guide more specialized mechanisms in the search for linguistic structure.
I believe that biological constraints give a great deal of control over a treatment plan.
Subsequent chapters cover plant structure and ecophysiology, latex production and harvest, genetics and breeding, biotechnology and molecular biology, soil tillage and crop establishment and nutrition, environmental and biological constraints, and ancillary income generation with Heavea honey and wood.
The papers here reflect this complexity, covering such topics as the multiple attributes of Pavlovian reward, time-discounted rewards in the orbitofrontal cortex and associated brain circuits, a model and its ability to reward learning and decision making, brain coding of reward episodes, reward-related responses in the human striatum, integration of cognitive and motivational information, the role of the dorsolateral prefontal cortex, basal ganglia mechanisms of eye movement, receptor theory and biological constraints, and what response rates tell us about dopamine and motivation.
Kurzweil, now in his late 50's, also envisions literal immortality for humans within his lifetime through the freeing of our intellect and consciousness from its mortal, biological constraints.
