چکیده
Objectives: To investigate the influence of wearing a pedometer and recording daily step counts on ambulatory activity. Methods: During the first visit to the laboratory, fifty healthy volunteers, blinded to the study aim, were provided with a sealed pedometer (New-Lifestyles NL-2000) and informed that it was a 'Body Posture Monitor' (sealed condition). Participants wore the pedometer throughout waking hours for one week. Upon returning to the laboratory step counts were downloaded and participants were informed that the device was actually a pedometer. They were requested to wear it unsealed for a second one week period, and to record their step counts in an activity log (unsealed condition). Results: Mean daily step counts reported in the sealed condition (9541±3186 steps/day) were significantly lower than step counts reported in the unsealed condition (11385±3763 steps/day) (p<0.001). Conclusions: Step counts increased significantly in the unsealed condition. Possible mechanisms for this include the knowledge of wearing a pedometer, the visible step count display and the completion of the activity log. This has validity implications for short-term studies (duration ≤ one week) investigating habitual pedometer-determined activity levels.

A list of requirements for a genetic programming representation is put forward and a representation separating the genotype and phenotype with a linear genome is presented. The target language for the genetic program is Perl. The mapping process, between the genotype and phenotype, converts blocks of four genes into program statements. This process is context-free and therefore provides inherit...
