As an attempt to reach physically inactive young people, especially girls, organized spontaneous sport (OSP) was implemented as a part of the state programme ‘The Sports Lift’ (2010). Projects, however, tended to primarily attract physically active boys rather than the actual target group. This problem calls for a qualitative approach to gain further knowledge about the interplay within the activities. Accordingly, this study aims to examine young people’s experiences of OSP activities with focus on participation, leadership and determining processes. To fulfil this purpose, a case study design was implemented. Data were collected through observations (pilot study) and semi-structured interviews with participants. The theoretical point of departure is developmental ecology, emphasizing the individual’s interaction with the multilevel environment. Results show that OSP is experienced as different from conventional organized sport. Further, the domination of boys is made possible through upholding the masculine sports norm, which is actualized within determining processes.  相似文献

Objectives: Slow-motion replays of foul play situations are now used in the education and training of sports officials. We investigated the impact of video speed on the decision-making process of association football referees and how this interacted with expertise. Methods: Three different groups of referees, varying in level of expertise, assessed video clips from an in-game perspective. Video clips represented corner kick and open play situations in which a foul occurred or not. For these foul/no foul situations, the referees had to make a technical (no foul; indirect free kick; direct free kick; or penalty kick) and a disciplinary decision (no card; yellow card; or red card), under both slow-motion and real-time viewing conditions. Accuracy scores were determined by comparing participant’s responses with the decisions of an expert panel. Results: Significant differences were observed across groups for foul/no foul situations, suggesting that the experts were able to process the available information more effectively than their less expert colleagues. The accuracy scores for the technical decision were higher in slow motion (67%) compared to a real-time viewing condition (56%), particularly for corner kick situations. No differences were found between real time and slow motion for the disciplinary decision. Conclusions: Slow-motion footage results in higher accuracy scores for complex technical decisions. These findings have implications for the use of slow-motion replays in the decision-making process of referees.  相似文献

Abstract

In this article, we study how mountain guiding was organized and regulated in Scandinavia and the Alps between 1820 and 2015 and focus on the most important differences and similarities in Scandinavia, and between Scandinavia and the Alps. We conclude that Switzerland and Chamonix (France) represent two different systems in the Alps during the nineteenth century. However, through the emergence of national and international guide unions the regulation of mountain guiding in the Alps today appears unified, with a close connection between national regulation and mountain guide unions. In Scandinavia, Norway and Sweden historically had similar practices organizing and regulating mountain guiding, where a relatively strong layman tradition emerged during the 1960s and 1970s. In 2008, legal decisions led Sweden to change its system to match the Alp model, while Norway held on to the layman tradition. This leaves mountain guiding in Norway as a distinctly less regulated field than in France, and Switzerland, as in and Sweden.  相似文献

TIJAH: Embracing IR Methods in XML Databases   总被引:1,自引:0,他引:1  
This paper discusses our participation in INEX (the Initiative for the Evaluation of XML Retrieval) using the TIJAH XML-IR system. TIJAHs system design follows a standard layered database architecture, carefully separating the conceptual, logical and physical levels. At the conceptual level, we classify the INEX XPath-based query expressions into three different query patterns. For each pattern, we present its mapping into a query execution strategy. The logical layer exploits score region algebra (SRA) as the basis for query processing. We discuss the region operators used to select and manipulate XML document components. The logical algebra expressions are mapped into efficient relational algebra expressions over a physical representation of the XML document collection using the pre-post numbering scheme. The paper concludes with an analysis of experiments performed with the INEX test collection.  相似文献

The purpose of this article is to investigate in situ the functions that knowledge has when used by students in argumentative discussions. The study is based on Dewey’s pragmatic perspective of knowledge, which means that knowledge gets its meaning in the activity at hand. The analyses are conducted using Transactional Argumentation Analysis, which is a combination of pragmatic meaning analysis and Toulmin’s argument pattern. The empirical material consists of video-recorded lessons from two seminars in a Swedish upper secondary school. The results show that knowledge plays a crucial role in the discussions. Six different functions are identified: emphasising complexity, clarifying and correcting, highlighting conflicting interests, providing evidence in a counterargument, predicting the consequences and adding support to an earlier claim. Knowledge also has general functions, such as justifying a claim, and is part of a collective process aimed at understanding the issues discussed. Further, the students use knowledge from different disciplines, such as environmental studies, history, politics, biology and human geography.  相似文献

In times of major global interconnectedness and environmental change, the pressure to identify, create, and exploit new resources is certain to intensify. Given that there are unavoidable trade-offs, conflicts, and arenas for violence involved when increasingly more material and immaterial things are turned into resources, we call for explicit research on the very process – a process that we label resourcification. The concept of resourcification shifts attention from essentialist queries about the nature of resources to a focus on the social processes through which things are turned into resources. In search of a better understanding of resources in the Anthropocene and, in particular, an understanding about the way resources emerge and are used, resourcification offers a new conceptual framework that allows for a systematic search for knowledge about the diversity of contexts, conditions, modes, and temporalities of resourcification. This Resourcification Manifesto offers a theoretical and empirical framework for a radical and disruptive approach to innovation, sustainability, and management studies and policies.  相似文献

The Comenius Action 3 courses were well accepted and showed high quality. But we need a structure for easily monitoring and evaluating these projects. The authors present in this article a pilot project with this purpose. It should be useful in order to implement a system of co-ordination and communication among the different projects, and to evaluate their effectiveness. It also seems essential in order to determine that the EU funds are well invested in projects that fulfil the objective of enhancing and strengthening the European dimension among teachers and teacher trainers.  相似文献

In this article the development and validation of the Beliefs about Primary Education Scale (BPES) are described. The BPES is an 18-item scale for assessing primary school teachers’ beliefs toward the nature of good education, subdivided in a transmissive dimension (TD) and a developmental dimension (DD). Both dimensions assess beliefs toward the general orientation and objectives of education, the nature of the educational content, and desirable ways of knowledge acquisition. An explorative study (n=352n=352) revealed a two-factor structure. Both dimensions were uncorrelated, which leads to the suggestion that teachers hold layered belief systems. In a following study (n=381), construct validity of the BPES was confirmed. The BPES’ DD and TD were shown to correlate significantly with constructivist and traditional teaching beliefs.  相似文献

The paper presents the approach to complex training of managers and faculty staff for system modernisation of Russian engineering education. As a methodological basis of design and implementation of the faculty development programme, the CDIO (Conceive-Design-Implement-Operate) Approach was chosen due to compliance of its concept to the purposes and tasks of engineering education development in Russia. The authors describe the structure, the content and implementation technology of the programme designed by Tomsk Polytechnic University and Skolkovo Institute of Science and Technology with the assistance of Chalmers University of Technology and KTH Royal Institute of Technology and other members of the CDIO Initiative. The programme evaluation based on the questionnaire results showed that the programme content is relevant, has high practical value and high level of novelty for all categories of participants. Therefore, the CDIO approach was recommended for implementation to improve various elements of the engineering programme such as learning outcomes, content and structure, teaching, learning and assessment methods. Besides, the feedback results obtained through programme participants’ survey contribute to identification of problems preventing development of engineering education in Russia and thus serve as milestones for further development of the programme.  相似文献
