Negative associations between physical activity (PA), physical fitness and multiple metabolic risk factors (MMRF) in youths from populations with low PA are reported. The persistence of this association in moderately-to highly active populations is not, however, well established. The aim of the present study was to investigate this association in a Brazilian city with high frequency of active youths. We assessed 122 subjects (9.9?±?1.3 years) from Muzambinho city. Body mass index, waist circumference, glycaemia, cholesterolaemia, systolic and diastolic blood pressures were measured. Maximal handgrip strength and one-mile walk/run test were used. Leisure time PA was assessed by interview. Poisson regression was used in the analysis. The model explained 11% of the total variance. Only relative muscular strength and one-mile walk/run were statistically significant (p?.05). Those who needed more time to cover the one-mile walk/run test had an increased in metabolic risk of 11%, and those with greater strength reduced the risk by about 82%. In conclusion, children and youths from an active population who need less time to cover the one-mile walk/run test or who had greater muscular strength showed a reduced metabolic risk. These results suggest that even in children and youths with high leisure time PA, a greater aerobic fitness and strength might help to further reduce their MMRF. 相似文献

Objective: Home visitation has been shown to be effective in reducing rates of child maltreatment and in enhancing psychosocial outcomes in children and their parents. Even when available, however, it is underutilized by parents in some urban settings. We tested a supplemental 10-session group intervention for its ability to increase active participation in home visitation, enhance the quality of caregiving behavior of parents, and improve social developmental outcome in children.Method: A randomized controlled design was utilized, involving two separate cohorts of parents of 3- to 18-month old infants, totaling 148 parent-child dyads. The intervention focused on practical experience in promoting parent-infant attachment relationships.Results: At 6 months follow-up, there was a substantial increase in the proportion of intervention group parents participating in home visitation, compared to parents in the control group (Fisher’s exact p = .008). Parents in the intervention group exhibited a trend for improvement in their capacity to appropriately interpret infants’ emotional cues (p = .08), independent of the effects of home visitation itself. Attrition in both the treatment and control groups was inversely associated with income and level of education.Conclusions: Group meetings may constitute an effective means of engaging stressed urban families in home visitation. 相似文献

In this study 1,453 Chinese high school and college students’ attitudes toward seeking professional psychological help and
factors contributing to attitude differences were examined. Results revealed that Chinese students possessed generally positive
attitudes and their attitudes were significantly associated with gender, prior counseling contact and prior knowledge about
counseling and psychology. Previous help-seeking behavior for a major problem was predictive of respondent attitudes. Students
with a broad range of help-seeking preferences had more positive attitudes than students with a narrower range. Students who
sought help from parents or teachers perceived counseling more positively than students not seeking such help; this result
was more significant for high school students. College students’ attitudes differed more in the area of whether or not to
seek help. In addition, family structure was related to two dimensions of attitudes toward help seeking—interpersonal openness
and stigma tolerance, but not to attitudes toward seeking psychological help. 相似文献

This paper reports on important learning processes emerging during adult mathematics classes that used a teaching approach compatible with a social constructivist theory of knowing. A cyclical teaching model encouraged much discussion about the mathematical problems presented to paired groups. Whole-class student-led sharing sessions allowed students to continue their interactive constitution of meaning and solutions.Comparisons of pre- and post-course scores on attitude and belief questionnaires indicated significant increases in positive attitudes and beliefs about mathematics and about themselves doing mathematics.The overall positive changes in scores on questionnaires are explained in terms of recurrent patterns in thinking inferred from data obtained by observation, interview, and reflective comments. Changes are explained in terms of the interactive effects of affective and heuristic processing during problem solving. Affective processes precipitated students' responsiveness, modifying the immediate learning context which, in turn, influenced the students' thinking, creating a snowballing effect on learning and affect. Changes were clearly facilitated by the interaction between students and by their shared understandings. 相似文献

This paper reports on the research trainingexperiences of Australian doctoral studentsworking in or funded by Cooperative ResearchCentres (CRCs), notes how their levels ofsatisfaction compare with those of theircounterparts in regular university science andtechnology disciplines and assesses to whatextent the CRC program is achieving its hopeswith respect to PhD training. Findings arebased on data from a survey of all enrolled PhDstudents in two research-intensive universitiesin Australia, together with supplementary datafrom student and supervisor interviews. Findings indicate that in the main, CRC-relatedPhD students fare well compared with theircounterparts in regular university departmentsand that on a number of indicators CRC-relatedstudents recorded higher levels of satisfactionwith their course experience. This situationsuggests that CRCs are playing a significantand worthwhile role in research training inAustralia. 相似文献

In this article the author's problematize the position of women in state school physical education, focusing in particular on the ‘instructors’ who were appointed to work with women teachers and senior girls, and prepare trainees at the Teachers College in South Australia. In exploring this little researched area, the article explores shifting representations of the woman ‘instructor’ from the 1920s to the late 1940s, highlighting the interplay of key discourses associated with age, gender, marital status, character, disciplinarity and physical activity. In addition, the authors explicate ways in which these discourses were interwoven in the career of May Cleggett, who for most of the period was the only woman physical education instructor in South Australian state schools. 相似文献

This paper may be read as a sequel to a 1995 paper, published in this journal, in which I predicted what sort of transformations and problems were likely to affect the development of the Internet and our system of organized knowledge in the medium term. In this second attempt, I look at the future developments of information and communication technologies and try to estimate what their impact on our lives will be. The forecast is that, in information societies, the threshold between online and offline will soon disappear, and that once there is no difference, we shall become not cyborgs but rather inforgs, that is, connected informational organisms. 相似文献
