The aim of this study was to investigate coaching performance in team sports taking leadership behaviours into focus. To do so, coaching performance was put in a literature-based frame and analysed with reference to a task structure based on the idea of hierarchical planning. The focus of the paper is on a mixed methods multi-strand study using qualitative as well as quantitative threads to develop and verify a set of coaching strategies focussing on teambuilding and team leadership. Qualitative analyses showed that coaches do have a clear understanding of forming and leading a team, which could be shown by a specific set of strategies being used by high performance coaches from different team sports (basketball, football, handball, and volleyball). These strategies could be confirmed in a sequential quantitative study analysing coaches’ and players’ attitudes towards the previously analysed schemes. The results of this study are discussed in terms of methodical and practical implications. 相似文献

News interviews are contexts in which political responsibilities are articulated and negotiated. Although the accountability interview is recognized as a commonsense practice in journalism, and the research on political interviews is substantial, it partly remains to explore how responsibilities are negotiated in different forms of questioning in journalism. This study investigates three generic forms of questioning: accountability questioning, the clarifying of promises, and the principal assessments. Key features of the different forms are specified. The empirical study investigates how the questionings are performed in news on industrial crises in Sweden, in the different political regimes in the 1970s and the 2000s. The data consist of 27 news interviews with the formally responsible Ministers. The method is based on Conversation Analysis and includes detailed analyses of questions and answers. The study shows (1) how the forms of questioning differ when it comes to the action agenda and in how responsibilities are invoked and negotiated; (2) how the questionings tend to reproduce particular expectations of Governmental interventions; (3) how increased assertiveness and adversarialness in interviewing coincide with reduced expectations of political responsibilities. 相似文献

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6–19 years old; European ethnicity) using a priori set criteria. A meta-analysis (Ncases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06–1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions. 相似文献

Maarif: transformation of a concept in the Ottoman Empire at the beginning of the nineteenth century
During the Ottoman period, ‘science (ilim, pl. ulûm)’, ‘knowledge (marifet, pl. maarif)’ and ‘technique (fen, pl. fünûn)’ emerged as three important concepts of knowledge. Maarif, which came into prominence with Selim III, began to undergo a semantic transformation together with the concepts of ulûm and fünûn and by the time of Mahmud II it had become an overarching concept representing the knowledge dimension of the new era. This article discusses the semantic transformation of maarif, focusing on the period between 1789 and 1839. This study applies the history of concepts approach developed by Reinhart Koselleck, whereby a synchronic analysis of the concept of maarif is undertaken alongside an examination of its diachronic dimension. This reveals an ambiguous and multi-dimensional structure and helps us to account for its evolution as an umbrella term. 相似文献

This design experiment aimed to answer the question of how to mediate the practices of authentic science inquiries in primary education. An instructional approach based on activity theory was designed and carried out with multi-age students in a small village school. An open-ended learning task was offered to the older students. Their task was to design and implement instruction about the Ice Age to their younger fellows. The objective was collaborative learning among students, the teacher, and outside domain experts. Mobile phones and GPS technologies were applied as the main technological mediators in the learning process. Technology provided an opportunity to expand the learning environment outside the classroom, including the natural environment. Empirically, the goal was to answer the following questions: What kind of learning project emerged? How did the students’ knowledge develop? What kinds of science learning processes, activities, and practices were represented? Multiple and parallel data were collected to achieve this aim. The data analysis revealed that the learning project both challenged the students to develop explanations for the phenomena and generated high quality conceptual and physical models in question. During the learning project, the roles of the community members were shaped, mixed, and integrated. The teacher also repeatedly evaluated and adjusted her behavior. The confidence of the learners in their abilities raised the quality of their learning outcomes. The findings showed that this instructional approach can not only mediate the kind of authentic practices that scientists apply but also make learning more holistic than it has been. Thus, it can be concluded that nature of the task, the tool-integrated collaborative inquiries in the natural environment, and the multiage setting can make learning whole. 相似文献

This paper presents a systematic review of university students’ emotions in connection with virtual learning based on 91 articles published between 2002 and 2017 in four international journals that focus on virtual learning and educational technology or on learning in higher education. These journals were considered potential channels for research on emotions in virtual learning and higher education. The objective was to analyse the articles for concepts and theoretical background related to virtual learning and emotions, contextual focus, methodological choice, and/or results. The review showed that the most common emotion-related concept was “satisfaction.” The most common context for the articles was a complete non-physical learning environment (e.g. Second Life). Approximately 60% of the articles used quantitative methods. The most common design for studying emotions was an explanatory design. Students’ emotions were mainly studied through concepts related to emotion (e.g. “satisfaction”). Yet only a few of the studies focused on the fluctuation of emotions in the course of events, relying instead on post hoc data that treat students’ emotions as traits rather than states. 相似文献

In this study, the use of inquiry methods, learning cycles, a conceptual change model and analogy in creating alternative
science texts was discussed. An alternative text on the topic of acids and bases was created by integrating the methods and
models discussed in this paper. The alternative text and a sample of a traditional text taken from a textbook, which is still
used in Turkish high schools, were given to two groups, totaling 42 pre-service teachers—the alternative text was given to
an experimental group and the traditional text to a control group—in an experimental setting and their understandings of acids
and bases were compared. In addition, in the second step of the study, the pre-service teachers read both texts and indicated
their preferences in terms of interest, understandability and helpfullness. 相似文献

This paper aims to make a contribution to the stream of literature on action research by describing a longitudinal collaborative research project which evolved out of a long-term, participation partnership with Volvo Cars. The collaboration was aimed at developing innovation capabilities in the company and accumulating knowledge on how capabilities are developed. The paper provides insights into the design of collaborative research projects to enable mutual, sustainable learning. It draws on key notions in the literature on collaborative management research and action learning, highlighting the research design of the project at Volvo Cars and its relations to action learning. The paper describes how the research design opened the way to establishing a learning system at Volvo Cars while simultaneously generating new scientific knowledge within the area of innovation capabilities. The paper provides rich and detailed data on a collaborative research setting and highlights key aspects related to organizing and undertaking collaborative research. 相似文献

In this paper we describe how progressive download and adaptive streaming can be combined into a simple and efficient streaming framework. Based on the MPEG-4 file format (MP4) we use HTTP for transport and argue that these two components are sufficient for specifying an open streaming architecture. The client selects appropriate chunks from the MP4 file to be transferred based on (1) the header information (i.e. the “moov” box) in the first part of the file and (2) his observation of network throughput. The framework is completely client driven which allows for better server scalability and reduces signalling overhead. We discuss architecture and implementation issues such as complexity, interoperability and scalability and compare to 3GPP PSS Rel-6 adaptive streaming when appropriate. Measurements from a simple MP4/HTTP streaming client are presented showing that appropriate chunks are selected such that increased reliability is achieved. 相似文献
