Economic implications of hormesis: some additional thoughts

Economic implications of hormesis.

The implications of hormesis for decision making about control of environmental exposures are examined. From an economic perspective, environmental exposures should be controlled to a level that optimizes health effects and minimizes control costs. The possibility that substances are, or may be, hormetic poses no fundamental challenge for economic analysis. In contrast with the linear no-thresh...

Treatment as prevention: some additional thoughts.

The authors of the paper ‘‘High HIV incidence among MSM prescribed postexposure prophylaxis in Amsterdam, 2000–2009: indications for ongoing sexual risk behaviour’’ by Sonder et al. are to be commended for conducting a relevant, timely study elucidating the complexities of depending on post-exposure prophylaxis (PEP) to reduce the acquisition and transmission of HIV among MSM. The study was wel...

Some Additional Thoughts on the Hybrid Paper

where k sd is the spin destruction rate constant between the alkali atom and some particle of type i, Γwall is the wall relaxation rate, and kdip is the He nuclear dipolar self relaxation rate constant. According to these equations, if one could provide enough laser power to keep a very high density of alkali metal polarized, then the He polarization could be, in principle, made to equilibrate ...

Global Warming Policy: Some Economic Implications

Many analysts believe that adverse climate changes in the form of global warming are— or soon will be—under way as the result of anthropogenic emissions of greenhouse gases. (See the box entitled “What Is Global Warming?”) The largest such source of these gases is carbon dioxide (CO2) resulting from the growing consumption of fossil fuels (petroleum products, natural gas, and coal). Consequentl...
