Physical fitness and muscular strength are important performance factors for Olympic class sailors, but the physical demands vary greatly between yacht classes, and limited information is available regarding the physical demands for the different crew positions. In the present paper, strength and aerobic capacity data from elite Olympic sailors are presented and compared with previous findings. Furthermore, a system for classification of Olympic class sailors is suggested. Peak aerobic capacity (peak oxygen uptake, VO(2peak)) and maximal isometric and isokinetic muscle strength of the knee extensors and flexors were assessed, together with the hamstring/quadriceps strength ratio (H/Q ratio). Peak aerobic capacity (ml O(2) . min(-1) . kg(-2/3)) was as follows: males - static hikers (n = 5) 215, s = 7; dynamic hikers (n = 8) 252, s = 17; trapezing helmsmen (n = 6) 234, s = 15; trapezing crew (n = 10) 239, s = 16; females - dynamic hikers (n = 6) 194, s = 16; trapezing crew (n = 2) 200, s = 13. Strength data for hikers, presented as peak moments (normalized to body weight) obtained during eccentric, isometric, and concentric contraction (Nm . kg(-1)) respectively were as follows: males - quadriceps: 3.66 (s = 0.68), 3.97 (s = 0.66), 1.82 (s = 0.34); hamstrings: 1.93 (s = 0.22), 1.38 (s = 0.41), 1.05 (s = 0.21); females - quadriceps: 3.84 (s = 0.71), 3.81 (s = 0.58), 1.60 (s = 0.28); hamstrings: 1.75 (s = 0.23), 1.10 (s = 0.16), 0.84 (s = 0.13). The peak moment based H/Q ratios for slow eccentric and concentric contractions were 0.42 (s = 0.11) and 0.39 (s = 0.04) for males and 0.43 (s = 0.06) and 0.39 (s = 0.04) for females respectively. Elite Olympic class sailors demonstrated high VO(2peak) values comparable to those observed in other non-endurance sports. The strength data revealed very high quadriceps strength for hikers, which is likely a result of the high muscle forces encountered during sailing, and a low H/Q ratio. To ensure optimal knee joint stabilization during sailing and other training activities, it is suggested that hikers should counter this strength imbalance by performing additional strength training for the hamstrings muscle group.  相似文献

This study explores the impact academic teachers’ writing of a teaching portfolio can have on their professional learning. Through an open-ended questionnaire, 26 academics from three faculties reported on insights, effects on teaching practice, and effects on collegial exchange that the portfolio writing entailed. We discuss how the experienced impact relates to the three competence levels excellence, expertise and scholarship of teaching and learning. With regard to academic development, we conclude that the writing of reflective teaching portfolios has the potential of contributing to an emerging academic community of practice characterised by a scholarly approach to teaching and learning.  相似文献

Background: Physical educators currently have a number of pedagogical (or curricular) models at their disposal. While existing models have been well-received in educational contexts, these models seek to extend students’ capacities within a limited number of ‘human activities’ (Arendt, 1958). The activity of human practising, which is concerned with the improvement of the self, is not explicitly dealt with by current models.

Purpose: The aim of the paper is to outline how a model of human practising related to movement capability could be enacted in physical education.

Findings: Building on a theoretical exposition of human practising presented in a separate paper, this paper provides a practically oriented discussion related to: (1) the general learning outcomes as well as teaching and learning strategies of the model; (2) an outline of five activities that describe how the model could be implemented; and (3) the non-negotiable features of the model.

Discussion: The model’s potential contribution to the ongoing revitalization of PE as an institutionalized educational practice is discussed. Points concerning how the model relates to wider physical cultures, its position regarding transfer of learning, standards of excellence, and social and cultural transmission are considered.

Conclusion: The paper is concluded with some reflections on pedagogical models generally and how they relate to the pedagogical model of practising movement capability presented in this paper.  相似文献

This paper presents an empirical study of automation in government digital systems. Previous studies have found that automated systems are not suited to cover all citizens equally and may cause administrative burdens on excluded citizens. The case presented in this study is the automated system for awarding child benefits in Norway. Based on data from the national registry, most recipients are awarded the benefit automatically. However, some citizens are not covered by the automation and must apply manually. The theoretical framing of the study combines modern and classic views of how citizens access public services by combining theory from recent literature on administrative burdens and the older theory of access. The data analysis is done with process mining, an innovative method of sorting and understanding data. The findings support previous findings of how registry data and automated computer systems in government can create inequality in service quality. Furthermore, the findings also show that low-income citizens are disproportionally required to apply manually. The study addresses questions concerning why automated systems fail to cover all citizens and the potential challenges generated by this exclusion when governments rely on computer systems in delivering welfare programmes. These are important considerations, as government digitalisation is increasingly innovating with automated systems to deliver public services.  相似文献

The study set out to explore an array of key competencies required by psychologists, along with a method for assessing them. The respondents (n?=?353) were a representative sample of young Finnish psychologists with professional experience of between 1 and 6 years. They were requested to rate 52 statements of competence. A set of explorative factor analyses was conducted separately for four predetermined competence domains: client management, personal/professional identity and autonomy, consciousness of professional limits and professional development. In total, the analysis generated 11 competence dimensions. It was found that the extent of work experience was related to the ratings of these competence domains. For instance, newly qualified psychologists tended to rate their competences higher than those of psychologists with a few more years of professional experience.  相似文献

Four-hundred-and-fifty-one in-service teachers from the Beijing municipality filled in a questionnaire containing a Teacher Efficacy for Inclusive Practices (TEIP) scale. The aim was to examine the factor structure of the TEIP scale among mainland Chinese in-service teachers, and to investigate the relationship between self-efficacy for inclusive practices, respondents' background factors and attitude towards inclusive education. The TEIP scale and its three sub-scales had good reliability. Confirmatory factor analysis gave support to a structure of three self-efficacy factors, efficacy in using inclusive instructions, efficacy in collaboration, and efficacy in managing behaviour.  相似文献

Previous studies pointed out that dealing with difficult behaviour is perceived by teachers as a major challenge in inclusive settings. However, research on the students' perception of the classroom behavioural climate (CBC) is rare. Therefore, this study aims to examine students’ perceptions of CBC and to identify predictors of CBC as well as associated variables. The sample consists of 650 German students from secondary schools (5th-9th grade) of whom 83 students are diagnosed with special educational needs (SEN). CBC was measured via four subscales (‘students’ possibilities to study and concentrating on teaching’, ‘disruptive behaviour’, ‘physical and psychological safety’ and ‘caring for the physical environment’). Results show significant differences in students’ perceptions of CBC between students from different school tracks. Furthermore, gender (being male) and SEN (having a) predict the perception of ‘physical and psychological safety’. Additionally, social inclusion, emotional experience as well as teacher support and care are associated with CBC. Accordingly, a positive CBC is important for the successful implementation of inclusive education: while diversity in classrooms is a challenge for behavioural climate, poor behavioural climate may also pose specific barriers to learning for some students with SEN and thus is a general challenge for equity in inclusive classrooms.  相似文献

eGov (eGovernment/eGovernance) is a complex endeavor involving many actors, ambitions, and perspectives. The field has, in research and in practice, over the years expanded its focus from service orientation to a comprehensive perspective with the ambition to integrate all of government in coherent action. Comprehensive integration requires a future-oriented perspective so investment is made in robust and flexible solutions meeting not only today's demands but also sustainable to meet those of the future. This paper addresses the use of the sustainability concept in eGov research. We discuss definitions and elements of sustainability and conduct a structured review of eGov literature investigating how various sustainability areas (social, economic, environmental and technical) are addressed. We find 21 overall themes in 94 papers, with the highest number in the “social” category. Two cross-cutting themes to which 21 overall themes relate are also identified; Decision-making and Infrastructure. Findings show that sustainability is mainly addressed narrowly, focusing on projects rather than general issues, and shallowly with a focus on single factors rather than the complex interaction among them, and with little foundation in sustainability theory. The paper contributes with an overview of themes in previous research as well as theory-based input for future research efforts on eGov sustainability, from a dynamic and sociotechnical sustainability perspective.  相似文献
