Ethics at home: informed consent in your own backyard

Keying off of a “fully informed consent letter” that consists of the text of her original letter to participants interspersed with insights gained after‐the‐fact, the author explores ethical and institutional power issues that arose as she conducted a qualitative research study in her home institution – her own “backyard” – and offers a critical examination of the concept of “informed consent,” calling for a radical revision of the standard notions of research ethics that blur ethical sensibilities.

The integrative curriculum combines subject‐matter studies, mini‐courses, and long term projects which allows for individual differences and provides a qualitatively different instruction program for the gifted.     

Submaximal exercise and maturation in 12-year-olds

The aim of this study was to examine the maturation responses of young people to submaximal treadmill exercise. Body mass was controlled using both the conventional ratio standard and allometric modelling. Ninety-seven boys and 97 girls with a mean age of 12.2 years completed a discontinuous, incremental exercise test to voluntary exhaustion. We measured peak oxygen uptake (VO2peak) and VO2 when running at 8, 9 and 10 km x h(-1). Sexual maturation was assessed visually using Tanner's indices of pubic hair. Peak VO2 was significantly higher in boys (P<0.001); this was still the case when the influence of body mass was covaried out. During submaximal exercise, no significant differences in absolute VO2 were observed between the sexes (P>0.05); however, values of VO2, expressed both in ratio with body mass and adjusted for body mass using allometry, were significantly greater in boys than in girls (P<0.001). For absolute VO2, significant main effects (P<0.05) were seen for maturity at each exercise stage. With the influence of body mass controlled using either the ratio standard or allometry, no significant main effects (P>0.05) for maturity were observed. Our results indicate that boys are less economical than girls while running at 8-10 km x h(-1) and that, independently of body mass, maturation does not influence the VO2 response to submaximal exercise.
