ABSTRACT

Aiming to evaluate the prevalence of unilateral/bilateral patellofemoral pain (PFP) among young dancers, and to investigate whether different factors are associated with PFP in young dancers, 132 dancers aged 12–14 years were assessed for PFP. Anthropometric parameters, proprioception ability, dynamic postural balance (DPB), and muscle strength were measured. PFP was found in 64.1% of the dancers. No significant differences in the prevalence of dancers with no, unilateral, or bilateral PFP at different ages were found. Significant age effects were found for anthropometric and developmental measurements, and for intensity of training. PFP effect was found for DPB asymmetry, ankle proprioception, and leg-length %height. A higher hip abductor/adductor ratio was associated with PFP in 14-year-old dancers. Binomial logistic regression showed that increased number of hours per day (h/day) and decreased number of hours per week (h/week), low proprioception scores, greater leg length as %height, and more anterior DPB asymmetry were significant predictors of PFP. In conclusion: unilateral/bilateral PFP is common among young dancers. Body morphology, reduced ankle proprioception ability, DPB asymmetry, and increased h/day of practice are associated with PFP. Dance teachers should start monitoring the impact of training and implement injury modification/prevention strategies when their students are at a young age.  相似文献   

Learning, knowing and being in the world: postformalism, Einstein, and lessons from a kid named Larry     

Shirley R. Steinberg 《Cultural Studies of Science Education》2009,4(3):553-558

I describe how Joe Kincheloe experienced learning from a peer during his pre-school life only to see how his friend was unable to succeed at school. Joe’s commitment to empowered cognition was grounded first, by his friend, Larry’s mentorship—teaching him the environmental nuances of the mountains in rural Tennessee, and secondly, the contradiction of schooling being unable to afford learning for Larry. This article discusses how Kincheloe became a scholar, the salience of Einstein’s work with his own, and the evolution of his research and scholarship. Examples of Kincheloe’s work addressed are: postformalism, bricolage, critical theory, and alternative knowledges, and how this work has contributed to science education.

Age Differences in Future Orientation and Delay Discounting   总被引：1，自引：0，他引：1  

Laurence Steinberg  Sandra Graham  Lia O'Brien  Jennifer Woolard  Elizabeth Cauffman  and Marie Banich 《Child development》2009,80(1):28-44

Age differences in future orientation are examined in a sample of 935 individuals between 10 and 30 years using a delay discounting task as well as a new self-report measure. Younger adolescents consistently demonstrate a weaker orientation to the future than do individuals aged 16 and older, as reflected in their greater willingness to accept a smaller reward delivered sooner than a larger one that is delayed, and in their characterizations of themselves as less concerned about the future and less likely to anticipate the consequences of their decisions. Planning ahead, in contrast, continues to develop into young adulthood. Future studies should distinguish between future orientation and impulse control, which may have different neural underpinnings and follow different developmental timetables.  相似文献   

Revisiting the impact of part-time work on adolescent adjustment: distinguishing between selection and socialization using propensity score matching     

Monahan KC  Lee JM  Steinberg L 《Child development》2011,82(1):96-112

The impact of part-time employment on adolescent functioning remains unclear because most studies fail to adequately control for differential selection into the workplace. The present study reanalyzes data from L. Steinberg, S. Fegley, and S. M. Dornbusch (1993) using multiple imputation, which minimizes bias in effect size estimation, and 2 types of propensity score matching, to account for selection effects. In this sample (N = 1,792; Grades 10-11, M = 16.26), youth who begin working more than 20 hr per week evince declines in school engagement and increases in substance use and delinquency compared with youth who remain unemployed. Conversely, working 20 hr or less a week has negligible effects, positive or negative, on academic, psychological, or behavioral outcomes.  相似文献   

Family rearing antecedents of pubertal timing   总被引：5，自引：2，他引：3  

Belsky J  Steinberg LD  Houts RM  Friedman SL  DeHart G  Cauffman E  Roisman GI  Halpern-Felsher BL  Susman E;NICHD Early Child Care Research Network 《Child development》2007,78(4):1302-1321

Two general evolutionary hypotheses were tested on 756 White children (397 girls) studied longitudinally: (1) rearing experiences would predict pubertal timing; and (2) children would prove differentially susceptible to rearing. Analysis of pubertal measurements, including some based on repeated physical assessments, showed that mothering and fathering, earlier and later in childhood, predicted pubertal development, but only for girls, with negative parenting appearing most influential; maternal harsh control predicted earlier menarche. Rearing effects varied by infant negative emotionality, proving stronger (and opposite) for girls who in infancy were lower rather than higher in negativity. Maternal menarche, controlled in all analyses, was a stronger predictor than rearing. Findings are discussed in terms of theory development, genetic and nutritional influences, and sample restrictions.  相似文献

A message to special education from mothers of disabled children     

Margaret A. Steinberg 《International Journal of Disability, Development & Education》1980,27(3):177-183

A conference, organised by the National Womens Advisory Council for women who had given birth to a disabled child, was attended by 150 participants from throughout Australia. The major issues and recommendations relevant to special education are presented in this paper. Issues included the need for accurate and honest information, particularly at birth or diagnosis, as well as the importance of sensitivity, and of skill in counselling, in all professional and community workers at all times. More comprehensive provisions in pre‐school, school and continuing educational services were requested and Governments were asked to look carefully at many problem areas, such as adequate financial support, accessible and cheap transport and the need to establish a ministry for the disabled. Everyone concerned with educational services should become advocates for the disabled and their families, particularly to improve community attitudes towards and services for the disabled.  相似文献   

Puberty Predicts Approach But Not Avoidance on the Iowa Gambling Task in a Multinational Sample          下载免费PDF全文

According to the dual systems model of adolescent risk taking, sensation seeking and impulse control follow different developmental trajectories across adolescence and are governed by two different brain systems. The authors tested whether different underlying processes also drive age differences in reward approach and cost avoidance. Using a modified Iowa Gambling Task in a multinational, cross‐sectional sample of 3,234 adolescents (ages 9–17; M = 12.87, SD = 2.36), pubertal maturation, but not age, predicted reward approach, mediated through higher sensation seeking. In contrast, age, but not pubertal maturation, predicted increased cost avoidance, mediated through greater impulse control. These findings add to evidence that adolescent behavior is best understood as the product of two interacting, but independently developing, brain systems.  相似文献   

The Relation Between Callous-Unemotional Traits,Psychosocial Maturity,and Delinquent Behavior Among Justice-Involved Youth

Callous-unemotional (CU) traits are a risk factor for severe and persistent patterns of juvenile delinquency. Given the influence of CU trait assessments in justice-system settings, it is important to determine whether the predictive utility of CU traits is conditional on the absence of protective psychosocial factors. Employing a sample of justice-involved male youth (N = 1,216, M_age = 15.29), this study examined whether psychosocial maturity (PSM) outweighs or attenuates the effect of CU traits on delinquency. Results indicated that youth with high CU traits or low PSM offended more during the year following their first arrest. Additionally, PSM moderated the relation between CU traits and offending, such that higher PSM was associated with less offending but only among low CU youth.  相似文献   

Age differences in strategic planning as indexed by the tower of London     

Albert D  Steinberg L 《Child development》2011,82(5):1501-1517

The present study examined age differences in performance on the Tower of London, a measure of strategic planning, in a diverse sample of 890 individuals between the ages of 10 and 30. Although mature performance was attained by age 17 on relatively easy problems, performance on the hardest problems showed improvements into the early 20s. Furthermore, whereas age-related performance gains by children and adolescents (ages 10-17) on the hardest problems were partially mediated by maturational improvements in both working memory and impulse control, improved performance in adulthood (ages 18+) was fully mediated by late gains in impulse control. Findings support an emerging picture of late adolescence as a time of continuing improvement in planned, goal-directed behavior.  相似文献
