The aim of this cross-sectional study was to compare bone mass in young female athletes playing ball games on different types of playing surfaces. About 120 girls, 9–13 years of age (10.6 ± 1.5 years old Tanner I–III) were recruited and divided into prepubertal and pubertal groups. The sample represented 3 groups of athletes: soccer (N = 40), basketball (N = 40), and handball (N = 40); and 6 different playing surfaces (soccer – ground, soccer – artificial turf, basketball – synthetic, basketball – parquet, handball – synthetic, and handball – smooth concrete). Total and regional body composition (bone mass, fat mass, and lean mass) were measured by dual-energy X-ray absorptiometry (DXA). The mechanical properties of the surfaces (force reduction, vertical deformation, and energy return) were measured with the Advanced Artificial Athlete (Triple A) method. The degree of sexual development was determined using Tanner test. The pubertal group showed that soccer players on the ground, basketball players on synthetic, and handball players on smooth concrete had higher values of bone mineral content (BMC) and bone mineral density (BMD) (< 0.05) than the soccer players on the artificial turf, basketball players on parquet, and handball players on synthetic. In conclusion, a hard playing surface, with less vertical deformation and force reduction, and greater energy return, is associated with higher levels of BMD and BMC in growing girls, regardless of the sport they practice.  相似文献

This study examines regret for withholding relational complaints. The study sample of 393 participants completed measures of irritant frequency, irritant importance, relational intimacy, emotional distress from withholding, and regret for withholding. Irritant frequency mediated the positive relationship between length of withholding and irritant importance. This process predicted less intimacy and more emotional distress from withholding, the latter of which related to regret. Alternative paths were also found between length of withholding and regret. Results offer important implications for the role of regret management in hurtful confrontations and may inform other avoidance forms.  相似文献

This paper reports an experimental study into the effects of cooperative and individualistic approaches in teaching Mathematics and English. The study was conducted at a Vacation Learning Camp (VLC) which was held for two weeks in one of the secondary schools in Singapore. This VLC was targeted at Secondary One pupils who were classified as below average based on general ability streaming.

The individualistic teaching approach was assumed to contribute to individual efforts while the cooperative teaching approach was expected to produce cooperativeness among the subjects. The results indicated that there were no significant differences in performances in the main effects classified as the treatment groups and the sex groups in both Mathematics and English; in Mathematics, the individualistic teaching approach was more effective for the male pupils whereas the cooperative teaching approach was more effective with females. However, in English, the results were reversed.

The female pupils in the cooperative group seemed to have improved in their attitude towards learning Mathematics whereas the male pupils in the individualistic group seemed to have a more positive attitude towards learning English.  相似文献

Intended as an introduction and overview, this article previews the other contributions to the topic and places them in a general introductory context. The basic question is why women, who are not currently confronted with legal or overt discrimination with regard to entering and even thriving in academic careers, are still underrepresented in the academic world in Europe, particularly in the upper echelons of academic governance and power. Several possible explanations are given, in particular the failure of women to be prepared from an early age to be competitive in ways which boys are taught to take for granted, and their failure, not so much to engage in networking, but to penetrate the networks which count, most or all of which are in fact male dominated. Among the strategies which women may use to gain both presence and power in the academic world, the use of women's studies programmes is ruled out as being ultimately counterproductive. Likewise doubt is cast on the long‐term effectiveness of affirmative action programmes. Only remedies specific to the individual conditions of each country will be really helpful in aiding women to be more numerous in higher education, particularly in positions of power. However, in all the countries in question, women must be socialized so as to be willing to adopt behaviours conducive to academic success, and they must bring to bear the full resources of the social protection and welfare systems, all of which in the different countries of the Europe Region favour not only the progress of women, but the rational use of human resources.  相似文献

A doula and expectant mother's view of birth is forever changed when she sees a midwife simply place a newly born child below her mother at the moment of birth. The pause that the mother experiences in this moment as she studies, touches, and claims her child prompts the author to reflect in this guest editorial on ways we might be disturbing the natural sequence of birth as we deliver babies directly to their mothers' chests.  相似文献

The purpose of this study was to determine the services required by students in special education programs and to estimate the cost of adequately funding special education in Taiwan. Questionnaires were administered to 300 special education teachers at the elementary school level to identify the services required. Thereafter, two focus group interviews were organized to determine the service categories and their cost. The results show that the costs for special education programs vary significantly according to severity of disability, and the weighting for mildly, moderately, and severely disabled students was found to be 3.7, 4.5, and 5.2, respectively. The costs also vary significantly according to the category of disability, and the weighting was found to range from 3.6 for emotionally disabled students and to 5.9 for hearing impaired students. These findings suggest that the current special education funding formula in Taiwan, which ignores these cost differences, should be revamped.  相似文献
