ABSTRACT
The aim of this study was to compare the effects of 20 min neuromuscular training with a programme of 10 min in youth football players. 342 (15.4 ± 1.7 years) male football players from 18 teams were included, and cluster-randomized by team into two intervention groups. Both groups performed an injury prevention programme twice a week over five months using the same exercises but a different duration. The first intervention group (INT10, n = 175) performed the programme for 10 min, the second intervention group (INT20, n = 167) for 20 min. Primary outcomes were lower extremity (LE) injuries. Secondary outcomes were injury type, severity, mechanism and compliance to the intervention. 13 teams with 185 players were included for final analysis. No significant group difference was found between INT10 (6.37 per 1000 h) and INT20 (7.20 per 1000 h) for the incidence rate ratio of the lower extremities (IRR = 1.03, 95% confidence interval 0.59, 1.79), nor for the distribution of injury location, type, severity or mechanism. The results show that performing preventive exercises for 10 min is no less effective than 20 min in youth football players. Shorter training sessions can, therefore, be effectively used for injury prevention. 相似文献

Traditional media have been changing in response to digitisation processes and the spread of the internet. This article looks at the consequences of technological change for the organisational structures of publishing houses in Germany, most of which are small to medium sized enterprises (SMEs). Following any decision to produce digital content, new tasks emerge which need to be fulfilled and publishing houses have to re-allocate appropriate responsibilities. The context of the preference for in-house or for external production is explored as is the precise identification of the managerial and technical skills demanded by a switch to digital publishing. The findings suggest the important role of strategic partnerships with service providers as well as with other publishing houses, especially for larger projects beyond the capabilities of SMEs. 相似文献

Filipino parents’ school choice and loyalty: a factor analysis 总被引:1,自引:1,他引:0

This quantitative study aims to ascertain the significant relationship existing between parents’ profile, and their school
choice and school loyalty. Data were gathered using the researcher’s two-part made instrument. Respondents were first asked
to fill in a robotfoto for purpose of profiling their baseline characteristics and were later asked to rate listed indicators, using a modified
8-point Likert scale. Using statistical tools such as the ANOVA, factor analysis, correlation, mean, and standard deviation,
data were treated indepth. It is interesting to note that although parents are loyal to their alma mater, this does not have
a much impact on their choice of school for their children. On the whole, parents’ choice of school is based on its indispensable
qualities. Among the three interval-scale profiles of the parent respondents such as age, income, tuition fee payment and
number of children, none of these relate to school choice, but age, income, and tuition fee payment negatively relate to school
loyalty. From their nominal-scale profiles, significant differences were noted in their school choice when grouped according
to civil status, place of work, and terms of payment. With respect to school loyalty, significant differences occurred in
their responses when classified according to gender, terms of payment and their active participation in the Parent-Teacher
Association (PTA). 相似文献

This article analyses the use of peer and self-assessment in oral presentations as complementary tools to assessment by the professor. The analysis is based on a study conducted at the University of Girona (Spain) in seven different degree subjects and fields of knowledge. We designed and implemented two instruments to measure students’ peer and self-assessment, and a rubric to guide the assessment process. Results were compared with the marks awarded by the professor. In contrast with studies by other authors, which show a high correlation between these different assessment systems, our study revealed significant deviations. Applying peer and self-assessment to oral presentation activities also demonstrates their formative value above and beyond their summative usefulness. 相似文献

Environmental education in schools is an important strategy in achieving environmental improvement. However, it needs to be based on children's understandings of environment rather than on assumptions of what children know and believe. This paper reports on a research project where school children's answers to a question 'I think the term/word environment means ' were analysed using the qualitative research method of phenomenography. Six distinct conceptions were isolated, ranging from the least sophisticated--environment as a place--to the most inclusive and expansive--environment and people in a relationship of mutual sustainability. An important qualitative difference was found between conceptions that treat the environment as an object and relational conceptions. The implications of these findings for environmental education are discussed. 相似文献

This article, derived from a three-year ethnography of distributed medical education provision in a Canadian university, explores the ways in which information and communication technologies are used by teachers and students in their everyday work within technologically rich teaching environments. The environments being researched are two university campuses: a campus at the main university site and a satellite campus in a neighbouring province. The article seeks to contrast dominant, institutional discourses of technology use in higher education teaching with the everyday practices of staff and students. The article concludes that there is a gap between policy and practice in distributed education and that the teaching and learning experience and context of staff and students in different sites need to be analysed in depth, in terms of: whether the experience of learning across sites can be positioned as being comparable; the extent to which technology ameliorates learning and teaching; and understanding the work done by staff. 相似文献

Burnout and quality of life (QoL) were assessed among 415 preschool and kindergarten teaching and assisting staff pertaining to Athens Municipal Nursery. MBI-ES and WHOQOL-BREF were used to collect data. Results revealed average to high levels of burnout; the emotional exhaustion was the salient dimension. QoL was satisfactory to high, except the ‘Environment’ section that was rated as moderate. Higher burnout was identified amongst those with permanent and open-ended work contracts, widows, the eldest, the more experienced and educated and those suffering from health problems. Lower QoL was associated with higher burnout. Data could guide multilevel policies for preventing burnout and improving QoL. 相似文献
