The Process of Choosing What to Study: A Longitudinal Study of Upper Secondary Students' Identity Work When Choosing Higher Education

This paper presents the first results from a longitudinal qualitative study following 38 Danish students' choice of higher education. By using a narrative psychological framework it is shown how the choice of higher education is embedded in various dilemmas, making it difficult for the students to make meaningful choices. They believe the choice should be unique and individual and that it should correspond with who they are and wish to become. However, the analysis shows that choosing what to study after upper-secondary school is a complex ongoing and social process, rather than an isolated individual event. Implications of these results are discussed and the educational system is urged to provide room for and facilitate students' production of choice narratives.     

Daycare Staff Emotions and Coping Related to Children of Divorce: A Q Methodological Study

This Q methodological study explores emotional experiences and coping of daycare staff when working with children of divorce and their families. Two main coping strategies among daycare staff were identified: 1) Confident copers, and 2) Non-confident copers. Interviews exemplify the two main experiences. Both groups may struggle with coping in this work. Still, Non-confident copers seem to experience more problems than do Confident copers. Both Confident and Non-confident copers find it difficult to work with parents who argue in front of the children. Accordingly, we suggest tailored education and counseling in this field to increase knowledge and coping among staff, to help them in their work with children of divorce.     

Improving the Bandwidth Selection in Kernel Equating

We investigate the current bandwidth selection methods in kernel equating and propose a method based on Silverman's rule of thumb for selecting the bandwidth parameters. In kernel equating, the bandwidth parameters have previously been obtained by minimizing a penalty function. This minimization process has been criticized by practitioners for being too complex and that it does not offer sufficient smoothing in certain cases. In addition, the bandwidth parameters have been treated as constants in the derivation of the standard error of equating even when they were selected by considering the observed data. Here, the bandwidth selection is simplified, and modified standard errors of equating (SEEs) that reflect the bandwidth selection method are derived. The method is illustrated with real data examples and simulated data.     

Children and youth in behavioural and emotional difficulties,skyrocketing diagnosis and inclusion/exclusion processes in school tendencies in Denmark

In parallel with a national school policy on an inclusive school with a marked reduction in the number of pupils who, due to their disruptive behaviour, are referred to educational provisions outside of the ordinary school environment, a sharp rise has been seen in the number of children and teenagers who are given a clinical diagnosis, first and foremost that of ADHD (Attention Deficit and Hyperactivity Disorders). Over just a few years, the skyrocketing of diagnoses has turned notions of children and teenagers with emotional and behavioural difficulties upside down. From being young people who should ‘just pull themselves together and behave properly’ many have become pupils with a neurological dysfunction that requires treatment. The article provides insight into how diagnoses over very few years have come into focus in schools and in special needs education, and how this has made a deep impression and changed understandings of the best possible special and general educational provisions for children and teenagers with behavioural and learning difficulties. The article focuses on trends in Denmark and therefore builds primarily on Danish sources.     

'It's Only the Sissies …': Analysis of Teaching and Learning Processes in Physical Education: A Contribution to the Hidden Curriculum

The article is a discussion and an analysis of an event observed in a critical classroom study on teaching and learning in physical education. It demonstrates how sociocultural discourses are embedded in children's and teachers' discursive practices [Fairclough (1992) Discourse and Social Change (Cambridge, Polity Press)] in the classroom, how discourses of physical education and discourses of gender relations are connected, and how these construct and are constructed by the social structures of the physical education lesson, and influence students' learning. Using the notion of situated learning [Lave & Wenger (1991) Situated Learning: Legitimate Peripheral Participation (Cambridge, Cambridge University Press); Wenger (1998) Community of Practice: Learning, Meaning, and Identity (Cambridge, Cambridge University Press)], the paper analyses how discourses in the physical education setting influence children's learning processes, and points to the different meanings the discursive practices observed in the classroom have for the girls as compared to the boys. This analysis allows for some concluding comments on learning and the hidden curriculum in physical education.     

The role of self-determined motivation in the understanding of exercise-related behaviours,cognitions and physical self-evaluations

Abstract

In this study, we investigated the adjustments to posture, kinematic and temporal characteristics of performance made by lower limb amputees during the last few strides in preparation for long jump take-off. Six male unilateral trans-femoral and seven male unilateral trans-tibial amputees competing in a World Championships final were filmed in the sagittal plane using a 100-Hz digital video camera positioned so that the last three strides to take-off were visible. After digitizing using a nine-segment model, a range of kinematic variables were computed to define technique characteristics. Both the trans-femoral and trans-tibial athletes appeared to achieve their reduction in centre of mass during the flight phase between strides, and did so mainly by extending the flight time by increasing stride length, achieved by a greater flexion of the hip joint of the touch-down leg. The trans-tibial athletes appeared to adopt a technique similar to that previously reported for able-bodied athletes. They lowered their centre of mass most on their second last stride (?1.6% of body height compared with ?1.4% on the last stride) and used a flexed knee at take-off on the last stride, but they were less able to control their downward velocity at touch-down (?0.4 m · s^?1). Both this and their restricted approach speed (8.9 m · s^?1 at touch-down), rather than technique limitations, influenced their jump performance. The trans-femoral athletes lowered their centre of mass most on the last stride (?2.3% of body height compared with ?1.6% on the second last stride) and, as they were unable to flex their prosthetic knee sufficiently, achieved this by abducting their prosthetic leg during the support phase, which led to a large downward velocity at touch-down (?0.6 m · s^?1). This, combined with their slower approach velocity (7.1 m · s^?1 at touch-down), restricted their performance.     

Yo-Yo IR2 testing of elite and sub-elite soccer players: Performance,heart rate response and correlations to other interval tests

Abstract

We examined performance, heart rate response and construct validity of the Yo-Yo IR2 test by testing 111 elite and 92 sub-elite soccer players from Norway and Denmark. VO₂max, Yo-Yo IR1 and repeated sprint tests (RSA) (n = 51) and match-analyses (n = 39) were also performed. Yo-Yo IR2 and Yo-Yo IR1 performance was 41 and 25% better (P < 0.01) for elite than sub-elite players, respectively, and heart rate after 2 and 4 min of the Yo-Yo IR2 test was 20 and 15 bpm (9 and 6% HRmax), respectively, lower (P < 0.01) for elite players. RSA performance and VO₂max was not different between competitive levels (P > 0.05). For top-teams, Yo-Yo IR2 performance (28%) and sprinting distance (25%) during match were greater (P < 0.05) than for bottom-teams. For elite and sub-elite players, Yo-Yo IR2 performance was correlated (P < 0.05) with Yo-Yo IR1 performance (r = 0.74 and 0.76) and mean RSA time (r = ?0.74 and ?0.34). We conclude that the Yo-Yo IR2 test has a high discriminant and concurrent validity, as it discriminates between players of different within- and between-league competitive levels and is correlated to other frequently used intermittent elite soccer tests.     

Between-school variation in physical activity,aerobic fitness,and organized sports participation: A multi-level analysis

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.     

Validity of the ActiGraph GT1M during walking and cycling

Abstract

The ActiGraph activity monitors have developed and newer versions of the ActiGraph accelerometers (GT1M, GT3X and GT3X +) are now available, including changes in hardware and software compared to the old version (AM7164). This is problematic as most of the validation and calibration work includes the AM7164. The aims of the study were to validate the ActiGraph GT1M during level and graded walking and to assess the potential underestimation of physical activity during cycling. Data were obtained from 20 participants during treadmill walking and ergometer cycling. Energy expenditure was measured via indirect calorimetry and used as the criterion method. Activity counts were highly correlated with energy expenditure during level walking (R² = 0.82) and graded walking at 5% and 8% (R² = 0.82 and R² = 0.67, respectively). There was no linear relationship between activity counts and energy expenditure during cycling. The average activity counts for all data points during cycling was 1,157 counts per minute (CPM) (SD = 974), and mean energy expenditure was 5.0 metabolic equivalents. The GT1M is a valid tool for assessing walking across a wide range of speeds and gradients. However, there is no relationship between activity counts and energy expenditure during cycling and physical activity is underestimated by ≈73% during cycling compared to walking.
