Four percent of the world’s population, or 265 million people, play football, and many players are injured every year. The present study investigated more than 1800 injuries in over 45,000 youth players participating in three consecutive international football tournaments in Denmark in 2012–2014. The aim was to investigate the injury types and locations in children and adolescent football players and the differences between genders and age groups (11–15 and 16–19 years of age). An overall injury rate of 15.3 per 1000 player hours was found. The most common injury location was lower extremities (66.7%), and the most common injury type was contusion (24.4%). Girls had a relative risk of injury of 1.5 compared with boys, p?p?p?相似文献

We discuss the eight papers in this issue of Cultural Studies of Science Education focusing on the debate over conceptual change in science education and explore the issues that have emerged for us as we
consider how conceptual change research relates to our practice as science educators. In presenting our interpretations of
this research, we consider the role of participants in the research process and contextual factors in conducting research
on science conceptions, and draw implications for the teaching of science.
Christina Siry is a PhD student in the Urban Education program of the City University of New York, and an instructor at Manhattanville College. Her research interests focus on pre-service and in-service preparation for the teaching of science and she is currently researching the use of coteaching and cogenerative dialogue in elementary teacher preparation for the teaching of science. In particular, she is exploring the role that shared, supported teaching experiences can have in the construction of new teacher identity and solidarity. She has worked as an elementary science specialist teaching children in grades K-5, and in museum settings developing science programs for teachers and children. In addition to the position at Manhattanville College, Chris is a lecturer in the University of Pennsylvania’s Science Teacher Institute where she teaches science pedagogy to middle school teachers. Gail Horowitz is an instructor of chemistry at Yeshiva University, and a doctoral candidate in science education at Teachers College. For many years, she has been involved in research and curricular design within the organic chemistry laboratory setting, focusing specifically on the design of discovery or puzzle based experiments. Her doctoral research focuses on the intrinsic motivation of pre-med students. She is interested in trying to characterize and describe the academic goal orientations of pre-med students, and is interested in exploring how the curricular elements embedded in project based laboratory curricula may or may not serve to enhance their intrinsic motivation. Femi S. Otulaja is currently a PhD student and an adjunct professor of science teacher education at Queens College of the City University of New York. As a science teacher educator, his research interests focus on the use of cogenerative dialoguing and its residuals, such as coteaching, distributed leadership, culturally responsive pedagogy, as research and pedagogical tools for engaging, training and apprenticing urban middle and high schools pre- and in-service science teachers as legitimate peripheral participants. He also encourages the use of these modalities as assessment, evaluation and professional development tools for teaching and learning science and for realigning cultural misalignments in urban classrooms. His theoretical framework consists of a bricolage of participatory action research, constructivism, critical ethnography, cultural sociology, sociology of emotions, indigenous epistemology, culturally responsive pedagogy, critical pedagogy and conversation analyses. In addition, he advocates the use of technologies as assistive tools in teaching science. Nicole Gillespie is a Senior Program Officer at the Knowles Science Teaching Foundation (KSTF). She is a former naval officer and high school physics teacher. Nicole received her PhD in science education from the University of California, Berkeley in 2004 where she was supported by a Spencer Dissertation Fellowship. She worked with the Physics Education Group at the University of Washington and conducted research on students’ intuitive ideas about force and model-based reasoning and argumentation among undergraduate physics students at Berkeley.

Ashraf Shady is a PhD candidate in the Urban Education program at the City University of New York Graduate Center; his strand of concentration is science, math, and technology. In his research he is currently using theoretical frameworks from cultural sociology and the sociology of emotion to examine how learning and teaching of science are enacted when students and their teachers are able to co-participate in culturally adaptive ways and use their social and symbolic capital successfully. His research interests focus on the use of cogenerative dialogues as a methodology to navigate cultural fields in urban education. Central to his philosophy as a science educator is the notion that teaching is a form of cultural enactment. As such, teaching, and learning are regarded as cultural production, reproduction, and transformation. This triple dialectic affirms that elements of culture are associated with the sociocultural backgrounds of participating stakeholders. Line A. Augustin received her doctorate degree in Chemistry (with a chapter of her dissertation on a case study of enactment of chemical knowledge of a high school student) and did a post-doc on Science Education at the Graduate Center, CUNY. She is currently teaching science content and methods courses in the Elementary and Early Childhood Education Department of Queens College, CUNY. She is interesting in investigating how racial, cultural, class and gender issues affect the ways that teaching and learning occurs in elementary classrooms, in understanding these issues and developing mechanism by which they can be utilized to promote better teaching and learning environment and greater dispositions towards science. She is also interested in what influences science teachers to change and/or to improve their teaching practices. 相似文献

IntroductionIn previous research projects and clinical settings, alcohol analysis in oral fluid (saliva) has been used as an alternative to breath or blood alcohol testing. In this study we examined whether it is possible to obtain clinically relevant data regarding alcohol consumption in individuals who recently consumed alcohol by analysing oral fluid samples when the recommended rinsing of the mouth is impossible before sample collection.Materials and methodsWe conducted a study of 89 nightclub patrons in Norway. Before collecting oral fluid samples and performing breath alcohol testing, participants were required to drink a glass of water to remove residual alcohol from the mouth. Oral fluid samples were collected with the Quantisal oral fluid collection device and analysed using an enzymatic method for alcohol. The alcohol concentration in the neat (undiluted) oral fluid was then calculated. Breath alcohol testing was performed using Lion Alcolmeter 500 instruments.ResultsNo false-negative or false-positive results for alcohol were detected in the oral fluid when compared with those in the breath. The Intraclass Correlation Coefficient of 0.40 indicated a poor correlation between alcohol concentrations in the two sample types.ConclusionsThe procedure for collecting oral fluid was suitable for the qualitative determination of alcohol intake but not for quantitative assessment. We recommend that oral fluid samples should not be used for estimating blood or breath alcohol concentrations in people who have recently consumed alcohol or non-alcoholic beverages, as recommended in the instructions for use. 相似文献

Do associations between maternal anxiety symptoms and offspring mental health remain after comparing differentially exposed siblings? Participants were 17,724 offspring siblings and 11,553 mothers from the Norwegian Mother and Child Cohort study. Mothers reported anxiety and depressive symptoms at 30 weeks’ gestation, and 0.5, 1.5, 3, and 5 years postpartum. Child internalizing and externalizing problems were assessed at ages 1.5, 3, and 5, and modeled using multilevel analyses with repeated measures nested within siblings, nested within mothers. Maternal pre- and postnatal anxiety were no longer associated with child internalizing or externalizing problems after adjusting for maternal depression and familial confounding. Maternal anxiety when the children were in preschool age, however, remained significantly associated with child internalizing but not externalizing problems. 相似文献

Abstract A large proportion of a child's day is spent at school interacting with certain physical surroundings, teachers, and school friends. Thus, schools could have a marked impact on establishing physical activity habits. The aim of the present study was to assess between-school variation in physical activity, aerobic fitness, and organized sports participation. Altogether, we tested 1766 nine- and fifteen-year-old children attending 242 school classes at 35 different schools in Denmark in 1997–2003. The intra-class correlation coefficient (ICC) for objectively assessed physical activity ranged between 0.06 and 0.18 depending on the dimension of physical activity and the time considered (i.e. school time vs. leisure time). For aerobic fitness, an ICC of 0.10 was observed, whereas that for organized sports participation ranged between 0.01 and 0.10 depending on the age group. Studying between-school variation in physical activity provides information about the extent to which children adjust their physical activity habits according to the social and environmental circumstances that they share, and helps to plan future school-based physical activity studies, especially in terms of sample size and power calculation. 相似文献

Based on a nationwide Norwegian survey among 3160 parents of children aged 6–12 years, this article identifies and discusses barriers for children’s engagement with nearby nature. A set of social factors related to time pressure are evaluated as more significant barriers than environmental factors such as accessibility, safety and landscape quality. Children’s free play in nearby nature does not seem to be an alternative to a target-orientated and time-scheduled everyday life. Instead, parents give themselves, other adults and public institutions more responsibility to stimulate increased nature contact. Despite strong traditions in outdoor life and good accessibility to nearby nature, social and cultural trends seem to influence children’s engagement with nature in the same way in ‘Green Norway’ as it does in many other European countries. Implications of the findings are discussed in terms of policy and promotion according to nature management and adults’ roles. 相似文献
