Kindergarten teachers’ accounts of their developing mathematical practice
2012
Published version of an article in the journal: ZDM. Also available from the publisher at: http://dx.doi.org/10.1007/s11858-012-0422-1 This study explores kindergarten teachers’ accounts of their developing mathematical practice in the context of their participation in a developmental research project. Observations and interviews were analysed to elaborate the accounts as regards orchestrating mathematical activities in the kindergarten. A co-learning agreement was established as collaboration between the kindergarten teachers and researchers. The study reveals that the kindergarten teachers argue that they have been empowered in developing an inquiry stance towards mathematics and mathemat…
Risk assessment of information on the subcombination Bt11 × 1507 × GA21, related to the application of Syngenta (EFSA‐GMO‐DE‐2011‐99) for authorisati…

Efsa Panel On Genetically Modified Organisms (gmo)StatementRequestor: European CommissionQuestion number: EFSA-Q-2016-00730; The EFSA Panel on Genetically Modified Organisms (GMO) has previously assessed the single events Bt11, MIR162, MIR604 and GA21 as well as different stacked events corresponding to combinations of these events. These maize events were found to be as safe as their conventional counterparts and other appropriate comparators with respect to potential effects on human and animal health and the environment. In its assessment of the four-event maize stack Bt11 9 MIR162 9 MIR604 9 GA21, the GMO Panel also assessed all the subcombinations of these events not previously assesse…
The historical development of the Mongolian media landscape : media ecology approach to the development of the Mongolian media from the 1200s to the …
2010
This media ecology thesis assesses the cultural impacts of communication technologies in Mongolia. Acknowledging the interconnectedness of media, its content, and human beings, it shows how changes in Mongolia's media have taken it through phases of orality, craft literacy, literacy, and into secondary orality. The research shows how Mongolia's media has developed over the centuries, how the social and media transformation in the USSR affected the development of Mongolia's media, and finally, to what degree and in what ways the aspects of oral and literate history, societal history and the media landscape relate to the popularity of participatory community radio in Ulaanbaatar. The backgrou…
Politics, planning, and ruling: the art of taming public participation

Public participation is still a democratic challenge to city and municipal governments. Numerous studies have suggested experiments on participative processes, and conflictual consensus is seen as ...
The temporal relations of adolescents' basic need satisfaction in physical education and global self-worth
2020
This study investigated the temporal relations of adolescents’ basic need satisfaction in physical education (PE) and global self-worth in a sample of 3,398 lower and upper secondary school students (49% boys, 51% girls, average age T1 = 15.00, SD = 1.79). Four models and competing hypotheses were tested, and the model with bidirectional paths specified showed the best fit to the data. The bidirectional effect estimates suggest not only that basic need satisfaction in PE predicts global self-worth development but also that adolescents’ perceptions of global self-worth predict the degree to which they experience basic need satisfaction in PE. Findings could suggest that students with low glo…
Global Self-Worth among Adolescents: The Role of Basic Psychological Need Satisfaction in Physical Education
2019
Global self-worth is important for healthy development and learning, and is therefore highlighted as a major aim in the Norwegian physical education (PE) curriculum. Based on prior research this study aimed to assess potential differences in global self-worth and contextual basic need satisfaction among 2854 adolescents (47.5% boys, 52.5% girls, ages 13 and 16) participating in different movement contexts, and to determine whether basic need satisfaction in PE relates to global self-worth. Structural equation modeling analyses indicate that basic need satisfaction in PE relates significantly to global self-worth. However, adolescents who do not participate in movement contexts outside schoo…
Relative age and perceptions of soccer specific skills among elite youth players in Norway
2019
One common feature among the selected players in talent development programs are the well-known relative age effect (RAE), characterized by a skewed birth distribution among selected players with an over-representation of players born early in the selection year. The aim of the present study was to examine potential differences in soccer-specific skills between players selected for national talent program born in the first half of the year compared to the players born in the second half of the year. A total of 753 elite male U 14 (N = 363) and U 13 players (N = 390) from 16 of 18 soccer regions in Norway participated. The results showed players born early in the selection year considered th…
Sport participation and vigilance in children: Influence of different sport expertise
2018
PURPOSE: The present study aimed to investigate the relationship between different types of sport expertise (externally-paced vs. self-paced sports) and vigilance performance in children by evaluating the cardiovascular fitness level of the participants. METHODS: Three groups of children (11.0 ± 0.2 years) differentiated in terms of their regular sport participation (football players, n = 20; track and field athletes, n = 20; non-athletic controls, n = 20) took part in the study. In one session, participants performed the Leger Multi-stage fitness test to estimate their aerobic fitness level. In another session, participants completed the Psychomotor Vigilance Task (PVT) to evaluate their v…
Associations between the dopamine D4 receptor gene polymorphisms and personality traits in elite athletes.
2019
Personality traits and temperament may affect sports performance. Previous studies suggest that dopamine may play an important role in behavior regulation and physical exercise performance. The aim of this study is to determine associations between dopamine D4 receptor gene (DRD4 Ex3) polymorphisms and personality traits (such as neuroticism, extraversion, openness, agreeability and conscientiousness) in elite combat athletes. A total of 302 physically active, unrelated, self-reported Caucasian participants were recruited for this study. The participants consisted of 200 elite male combat athletes and 102 healthy male participants (control group). For personality trait measurements, the NEO…
8.4GHz VLBI observations of SN2004et in NGC6946
2007
We report on 8.4GHz Very Long Baseline Interferometry (VLBI) observations of the type II-P supernova SN2004et in the spiral galaxy NGC 6946, made on 20 February 2005 (151 days after explosion). The Very Large Array (VLA) flux density was 1.23$\pm$0.07 mJy, corresponding to an isotropic luminosity at 8.4GHz of (4.45$\pm$0.3)$\times10^{25}$ erg s$^{-1}$ Hz$^{-1}$ and a brightness temperature of (1.3$\pm$0.3)$\times10^{8}$ K. We also provide an improved source position, accurate to about 0.5 mas in each coordinate. The VLBI image shows a clear asymmetry. From model fitting of the size of the radio emission, we estimate a minimum expansion velocity of 15,700$\pm$2,000 km s$^{-1}$. This velocity…
