So far in the context of genetics, policy change has not generally been driven by evidence and facts, but rather by debate and foresight based on plausible arguments.
Innovative health activities in Ghana are generally being driven by individual entrepreneurs relying on international linkages for access to physical inputs, knowledge and/or markets, who are not well-connected to other local firms, research organizations or government bodies (though there are exceptions such as the Food and Drugs Board).
As a neighborhood vehicle, the Kenguru has a top speed of about 25 miles per hour and generally cannot be driven on highways.
The functional part of the molecule that accomplishes peptide presentation (contact residues of the antigen-binding sites [ABS]) and displays most of the polymorphism is generally thought to be driven by pathogen-driven selective pressures [ 9].
Gas migration on coal matrix is generally believed to be driven by diffusion (Thimons and Kissell 1973; Gray 1987a, 1987b).
Cancer resistance to therapy occurs through a selection process generally thought to be driven by mutations.
The shape changes are generally accepted to be driven by the actin cytoskeleton, which together with accessory proteins make up the cell cortex.
Genes which encode proteins with antibacterial, antiviral and antifungal activity are generally believed to be driven by co-evolution of host and pathogen and therefore pathogenic agents provide some of the strongest selective pressures on human evolution.
The role of ABC transporters in the zebrafish developmental processes and in dealing with chemical exposure is, however, as yet unknown, and uptake and distribution of chemicals are generally assumed to be driven by passive diffusion.
For example, variation in microbial community abundance and activity in surface sediments is generally assumed to be driven by changing environmental conditions, such as pH and salinity, or stochastic processes, such as sediment turnover during a storm.
