Purpose: The benefits of physical activity (PA) in preventing abdominal obesity are well recognized, but the role of different sport disciplines remains open. We aimed, therefore, to investigate how participation in different sport disciplines, and the number and types of sports engaged in are associated with waist circumference (WC) in young adulthood. Methods: This population-based cohort study comprised 4027 Finnish twin individuals (1874 men), with a mean age of 34 y (32–37), who answered a survey, including self-measured WC. We extracted the number and identified the types (aerobic, power, and mixed) of the different sport disciplines respondents reported participating in. Results: The number of sport disciplines participated in was inversely associated with WC, the linear decrease averaging 1.38?cm (95% CI 1.10–1.65) per each additional sport discipline. The result persisted after adjustment for the main covariates, such as volume of PA and diet quality. Among dizygotic twin pairs discordant for sports participation (0–2 vs. 5 or more disciplines), the mean within-pair difference in WC was 4.8?cm (95% CI 0.4–9.1) for men and 11.2?cm (95% CI 4.4–18.0) for women; among discordant monozygotic pairs, no differences were observed. In men, all three types of sports were individually associated with smaller WC, while in women, only mixed and power sports showed this association. Conclusions: Participation in several sport disciplines and sport types was associated with smaller WC among young adults in their mid-30s. Shared genetic background may explain some of the associations. 相似文献

Studies show that teachers and students use humour when communicating with each other in a science education context. This study investigates the use of humour during a collaborative inquiry laboratory task on an undergraduate chemistry course and an undergraduate physics course. Seven groups of students working on a collaborative inquiry task were recorded on video. The videos were analysed utilising an analytical framework based on conversation analysis. During the tasks, humour was used in a dynamic way and the role of humour changed as the inquiry progressed. As expected, humour was used to create a group identity and to regulate negative emotions such as anxiety, frustration, uncertainty, boredom and disappointment. Humour also had an integral role in collaborative decision-making, for example in proposing and evaluating new ideas. Awareness of how humour can contribute to the regulation of emotions and collaborative decision-making might help students and teachers to better utilise humour in inquiry and learning. 相似文献

This socioculturally informed study investigated children’s sense of agency in relation to their everyday life in preschool. The empirical data comprised focus groups reflection situations wherein Finnish preschool children (n. 19, aged 6–7) reflected on their everyday life with the help of photographs and drawings they made. Building on a situative and discursive take on the sense of agency, the results of this study highlight the different forms of the sense of agency talked into being in the focus groups. The results also provide evidence of the different activities within which children’s sense of agency was embedded. In addition, the study also engages with the notion of radical passivity to theoretically explore the borders of the concept of the sense of agency. In all, the study demonstrates the mundane side of children’s sense of agency and its subtle dynamics in day-to-day life in preschool. 相似文献

In our present research we address the question of whether it is valid to apply the Quality Assurance and Evaluation (QAE) umbrella concept, which was formulated to explain new phenomena in European educational governance, to similar developments in Brazilian basic education. This led us to reflect on the possible pitfalls and potential strengths of using umbrella concepts as analytical tools. This article presents this exploration and its operationalisation. We confronted in-built assumptions in QAE with the contested, consensual and creative use of the notion of quality in Brazilian basic education, and looked for relationships. Our analysis shows that the Brazilian developments reiterate the relationships concerning global interconnectivity, and challenges those pertaining to conformity. We argue that the main risks of using umbrella concepts seem to concern the re-production of understandings, which frequently leads to the disregarding of deviation. 相似文献

This paper is based on a pedagogical action research initiative that explores what constitutes the ‘lived pedagogy’ of the classroom from the pupils' perspective. Photography and group interviews were utilised to allow pupils to express their perspectives. The results show that pupils considered situations meaningful when they were able to work, solve problems and create items together. The pupils appreciated situations in which they experienced a sense of belonging and could influence the use of time and space during the school day. The paper considers possibilities and challenges related to acknowledging pupils' voices in the lived pedagogy of the classroom. 相似文献

The factor mixture model (FMM) uses a hybrid of both categorical and continuous latent variables. The FMM is a good model for the underlying structure of psychopathology because the use of both categorical and continuous latent variables allows the structure to be simultaneously categorical and dimensional. This is useful because both diagnostic class membership and the range of severity within and across diagnostic classes can be modeled concurrently. Although the conceptualization of the FMM has been explained in the literature, the use of the FMM is still not prevalent. One reason is that there is little research about how such models should be applied in practice and, once a well-fitting model is obtained, how it should be interpreted. In this article, the FMM is explored by studying a real data example on conduct disorder. By exploring this example, this article aims to explain the different formulations of the FMM, the various steps in building a FMM, and how to decide between an FMM and alternative models. 相似文献

This paper outlines a dialectical conceptualisation of children’s agency for the purposes of multidisciplinary educational theory and practice. We illuminate five contradictory but connected dimensions of children’s agency, or the dialectics of agency, identified from theoretical debate between sociologically and psychologically oriented educational literature: Agency (1) as enacted and imagined; (2) as situatively emergent and progressively developmental; (3) as dependence and separation; (4) as mastery and submission; and (5) as control and freedom. We examine these contradictions ‘at work’ in an ethnographic early education case study. We argue that the children’s struggles towards agency and adults’ efforts and failures to support children in their struggles can be conceptualised as a dialectical movement that has a potential to develop the educational practice itself. Our dialectical reading of both data and theory helps to highlight the challenges the practitioners face when supporting children’s agency and the solutions they implement when doing so. 相似文献

The paper focuses on the emergence of Finnish computer culture in the late 1950s. The introduction of computers is studied by using a wide range of source material of popular media, such as commercial and company promotion films, newspapers, popular magazine articles, cartoons and comic strips. The paper argues that the introduction of the new computing technology was deeply experienced with the help of popular media, where the technological capabilities of computers as thinking and sensing ‘all-purpose machines’ were translated into several media-specific audio-visual forms. Computers were represented as sensing and sensible technology, a rubric that was remediated by the help of old media. In this process, the spectacularization of computers worked not only as an innocent fabulation of the computers to convince the ‘general public’ but to create a certain social arrangement particular to this spectacle. The idea that the end-user is cut off from the actual processes of the computer, as suggested by such media historians as Friedrich Kittler, was evident already in the earlier construction of computing culture in the mainframe era. 相似文献

Abstract This article looks at how the Finnish education system is approaching the emergence of audio‐visual material as a teaching aid, and the problems faced by the producers of this material in coping with the different types of equipment and the differences in values between the target groups of teachers and pupils. It indicates how teachers must develop and how educationalists must be prepared to accept financial and material help from business and industry if advances are not to be delayed. 相似文献
