A final limitation is that recruitment from an occupational setting may predispose our population to biases such as the "healthy worker survival effect," whereby exposed men who were eligible for recruitment may have relatively low susceptibility to the effects of benzene (Garcia and Checkoway 2003).
It is very much an extension of the BAC's scratch methodology, whereby artists expose work-in-progress to audiences at various points in the development process and build on the feedback.
Some of these employment effects may be caused or exacerbated by the phenomenon of group polarization, whereby people exposed primarily to those who share similar views ultimately adopt more extreme positions (e.g., Sunstein 2005).
Analysis suggested a 'chronicity' effect, whereby offspring exposed to maternal depression over a greater number of developmental periods experienced more severe depression in adulthood (n = 100, rs = 0.31, P<0.01).
Relaxation training was founded, in part, by Joseph Wolpe, a South African-born psychiatrist who cultivated what is called "systematic desensitization," a method whereby you gradually expose a person to his greatest fears while helping him "go rag doll".
If the ages can be correctly interpreted in the context of a process whereby they were exposed near the surface of Itokawa, they can potentially provide us with clues to the dynamical evolution of Itokawa itself.
In the current study, a modified vitrification protocol with three steps was investigated, whereby embryos were exposed to solutions containing increasing amounts of glycerol and ethylene glycol for fixed time periods.
To achieve this we utilised a protocol whereby rats were exposed to repeated phase shifts in the photoperiod throughout gestation and for 1 week after birth, thereby significantly disrupting rhythmicity during this period.
Ischaemic preconditioning (IP) describes the process whereby a tissue exposed to brief sublethal periods of ischaemia becomes protected from longer lethal episodes of ischaemia.
Therefore the biofilm mode of growth, by hindering diffusion, could provide an ideal environment whereby microorganisms are exposed to sub-lethal doses of antimicrobial thus providing a selective pressure for the emergence of resistance.
