The relation between behavior problems and peer preference in different classroom contexts. Conduct Problems Prevention Research Group.

This study tested two alternative hypotheses regarding the relations between child behavior and peer preference. The first hypothesis is generated from the person-group similarity model, which predicts that the acceptability of social behaviors will vary as a function of peer group norms. The second hypothesis is generated by the social skill model, which predicts that behavioral skill deficiencies reduce and behavioral competencies enhance peer preference. A total of 2895 children in 134 regular first-grade classrooms participated in the study. Hierarchical linear modeling was used to compare four different behaviors as predictors of peer preference in the context of classrooms with varying levels of these behavior problems. The results of the study supported both predictive models, with the acceptability of aggression and withdrawal varying across classrooms (following a person-group similarity model) and the effects of inattentive/hyperactive behavior (in a negative direction) and prosocial behavior (in a positive direction) following a social skill model and remaining constant in their associations with peer preference across classrooms. Gender differences also emerged, with aggression following the person-group similarity model for boys more strongly than for girls. The effects of both child behaviors and the peer group context on peer preference and on the trajectory of social development are discussed.

[Cigarette smoke and bronchial hypersensitivity].

Among intrinsic factors which may affect the onset of COPD, bronchial non specific hyperresponsiveness seems to play an important, even though, ill-defined role. Attention is drawn to 2 major points: 1) Cigarette smoking habit may increase airway responsiveness? 2) Any possible hyperresponsiveness induced by smoking may be relevant in the development of COPD? At present, only point 1 may be positively answered; point 2 will be clarified by means of perspective and long-term surveys, we have not achieved yet. Our cross-sectional study showed a significant influence of smoking on bronchial responsiveness in absolutely asymptomatic subjects and with airway caliber absolutely in the normal range. This kind of influence resulted to be dose-dependent. Furthermore a noxious role of smoking has been observed, the greater effect the higher amount of cigarettes/day smoked. Moreover this acute role of smoking has been remarked by the trend of bronchial responsiveness of past-smokers, the more similar to non smoker's, the more far was smoking cessation.
