The aims of this study were to analyse recreational sea kayaking and touring incidents in Norway with a specific focus on wind conditions and to elaborate on practical implications for the prevention of future incidents. We included 49 incidents reported by the media between 2000 and 2014. Incidents occurred in various wind conditions, but most incidents (60%) occurred in moderate to strong breezes (9–14 m/s). Wind strength and direction were generally forecast accurately and conditions were mainly stable throughout the day of the incident. Thus, sea kayaking and touring incidents in Norway seem to happen in various wind conditions; however, paddlers should have been well informed and aware of the hazards they were facing. Future incidents could be prevented by increasing sea kayakers’ situation awareness through discussion of experts’ decision-making processes and the arrangement of situated learning experiences in realistic settings.  相似文献

This study examined salivary cortisol, a stress-sensitive hypothalamic-pituitary-adrenocortical (HPA) axis hormone in 20 infants (12 females; M age = 10.8 months) and 35 toddlers (20 females; M age = 29.7 months) in full-day, center-based child care. Samples were taken at approximately 10:00 a.m. and 4:00 p.m. at child care and at home. At child care, 35% of infants and 71% of toddlers showed a rise in cortisol across the day; at home, 71% of infants and 64% of toddlers showed decreases. Toddlers who played more with peers exhibited lower cortisol. Controlling age, teacher-reported social fearfulness predicted higher afternoon cortisol and larger cortisol increases across the day at child care. This phenomenon may indicate context-specific activation of the HPA axis early in life.  相似文献

Background: From previous research among science teachers it is known that teachers’ attitudes to their subjects affect important aspects of their teaching, including their confidence and the amount of time they spend teaching the subject. In contrast, less is known about technology teachers’ attitudes.

Purpose: Therefore, the aim of this study is to investigate Swedish technology teachers’ attitudes toward their subject, and how these attitudes may be related to background variables.

Sample: Technology teachers in Swedish compulsory schools (n = 1153) responded to a questionnaire about teachers’ attitudes, experiences, and background.

Methods: Exploratory factor analysis was used to inwvestigate attitude dimensions of the questionnaire. Groupings of teachers based on attitudes were identified through cluster analysis, and multinomial logistic regression was performed to investigate the role of teachers’ background variables as predictors for cluster belonging.

Results: Four attitudinal dimensions were identified in the questionnaire, corresponding to distinct components of attitudes. Three teacher clusters were identified among the respondents characterized by positive, negative, and mixed attitudes toward the subject of technology and its teaching, respectively. The most influential predictors of cluster membership were to be qualified for teaching technology, having participated in in-service-training, teaching at a school with a proper overall teaching plan for the subject of technology and teaching at a school with a defined number of teaching hours for the subject.

Conclusions: The results suggest that efforts to increase technology teachers’ qualifications and establishing a fixed number of teaching hours and an overall teaching plan for the subject of technology may yield more positive attitudes among teachers toward technology teaching. In turn, this could improve the status of the subject as well as students’ learning.  相似文献

In this article we examine how the introduction of an output-based funding scheme in Norwegian public higher education in 2003 affects pass requirement standards. Based on a survey of faculty at the institutions concerned, we find that the propensity to expect that the new funding model will affect the failing/non-failing decision in exams is higher among faculty at the regional colleges than among traditional university faculty. This result is robust when we verify a range of individual characteristics of the respondents.  相似文献

Introduction: Successful rowers are heavier and taller than their opponents, but the effect of these variables on long-term career attainment in juniors has not been examined. We therefore analysed this in a large sample of elite German junior rowers. Methods: Former German Junior National Team rowers (N?=?910; 399 females) were grouped according to their highest career attainment, i.e., participation in U19-, U23-, Senior World Championships or Olympic Games (OG). Differences in standing height (SH), body mass (BM) and body mass index (BMI) between groups were analysed using unpaired t-tests and magnitude-based inferences (MBI), effects of anthropometrics on career attainment were analysed with a proportional odds model. Interquartile ranges of the OG group were used to define normative data ranges. Results: SH and BMI very likely differed between career attainment in females. The same was found in males for SH and BM. BM (odds ratio (OR)?=?0.958, P?=?.0171) and BMI (OR?=?0.787, P?=?.0004) had a significant effect on career attainment in females as SH (OR?=?1.072, P?=?.0002) and BM (OR?=?1.049, P?=?.0004) had in males. Interquartile ranges of SH and BM were 178–184?cm and 68–73?kg in females, 190–196?cm and 84–93?kg in males. Conclusion: Anthropometric characteristics at junior age affect long-term career attainment even within elite U19 National Team rowers, underlining the relevance of anthropometric assessments and their consideration for talent identification and development programmes in rowing. We provide evidence-based normative data that rule out an anthropometric limitation of junior rowers for career progression to Olympic level.  相似文献

Berg, G. 1982. Research into the School as an Organization. I: A Presentation and Discussion of Research Literature with a Bearing on the School as an Organization. Scandinavian Journal of Educational Research 26, 95‐117. Only to a limited extent has the school as an organization been the subject of any really systematic research, whether on the part of educationalists, sociologists or general organizational theorists. In this article a number of research projects focusing on the school as an organization are described and discussed. Previous research in this field has been either functionalist or structuralist in approach. Nevertheless, certain concepts are common to the analyses of all the researchers referred to here: all describe the school as an organization in terms of professionalism and bureaucracy. We would add that the school can also be described as a coercive organization.  相似文献
