This study is about the relation between self-efficacy expectations and the attitude towards child and youth obesity, as well as the role of the school in this matter. A questionnaire was given to a sample of 436 trainee physical education teachers from eight universities in Andalusia (Spain). The questionnaire was a version of Teaching Self-Efficacy in Higher Education (Prieto, 2007) and of Perceptions of Youth Obesity among Physical Educators (Greenleaf and Weiller, 2005). The results indicated that those trainees who possessed a higher level of perceived self-efficacy for the assessment of not only their own teaching, but also of the knowledge acquired by overweight students and of school intervention in their learning process, tended to show more favourable attitudes towards the educational treatment of child and youth obesity, and towards obese students’ fitness and healthcare. The trainees with a perceived higher level of self-efficacy for the assessment of the progress made by overweight students and with a more favourable disposition towards revising their teaching practice tended to show a more negative attitude towards obese people.

SummaryRectal swabs from 1566 healthy American children who had no contact with clinically recognized cases of poliomyelitis were tested in monkey kidney tissue cultures. Among the 31 cytopathogenic agents which were recovered, 5 were poliomyelitis virus (three Type 2 and two Type 3), one was a group B Coxsackievirus, and 25 belonged to a hitherto unidentified group of enteric viruses. This new group of human enteric or HE viruses is antigenically unrelated to the so-called “orphan viruses” recovered in tissue culture by Melnick and by Steigman et al., from the stools of patients with suspected nonparalytic poliomyelitis. 22 of (these 25 new viruses belong to 3 distinct serologic types (8 were Type 1, 11 Type 2 and 3 Type 3). The HE 1, HE 3 and the 3 unclassified strains were neutralized by human gamma globulin while the HE 2 virus was not. The HE 1 and HE 2 strains produced neither paralysis nor any significant lesions after intraspinal injection in cynomolgus monkeys. The 5 poliomyelitis viruses were al...
