Abstract Until recently, the physiological demands of cycling competitions were mostly reflected by the measurement of heart rate and the indirect estimation of exercise intensity. The purpose of this case study was to illustrate the varying power output of a professional cyclist during flat and mountain stages of a Grand Tour (Giro d'Italia). Nine stage recordings of a cyclist of the 2005 Giro d'Italia were monitored using a mobile power measurement device (SRM Trainingssystem, Julich, Germany), which recorded direct power output and heart rate. Stages were categorized into flat (n = 5) and mountain stages (n = 4). Data were processed electronically, and the overall mean power in flat and mountain stages and maximal mean power for various durations were calculated. Mean power output was 132 W ± 26 (2.0 W · kg?1 ± 0.4) for the flat and 235 W ± 10 (3.5 W · kg?1 ± 0.1) for the mountain stages. Mountain stages showed higher maximal mean power (367 W) for longer durations (1800 s) than flat stages (239 W). Flat stages are characterized by a large variability of power output with short bursts of high power and long periods with reduced intensity of exercise, whereas mountain stages mostly require submaximal, constant power output over longer periods. 相似文献

ABSTRACT 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 school report significantly lower basic need satisfaction in PE compared to their sports-active peers, and could possibly therefore experience reduced global self-worth development through PE. Findings support research showing that sports active youth reap most of the bene?ts of PE, and thus, that PE violates the principles of equal education. 相似文献

It was investigated how domain-specific knowledge, fluid intelligence, vocational interest and work-related self-efficacy predicted domain-specific problem-solving performance in the field of office work. The participants included 100 German VET (vocational education and training) students nearing the end of a 3-year apprenticeship program as an industrial clerk (n?=?63) which usually leads to a position in office work, lower or middle management, or a similar apprenticeship program to become IT-systems management assistants (n?=?37). The participants worked on three computer-based problem scenarios dealing with operative controlling, a relevant domain to both training occupations, and completed further assessments to measure the variables listed above. Theoretical considerations, prior research and domain analyses suggested that industrial clerks would have greater domain-specific problem-solving competence (H1a) and domain-specific knowledge (H1b) than IT-systems management assistants and that domain-specific knowledge would be the strongest predictor of problem-solving competence (H2: “knowledge-is-power” hypothesis); all hypotheses were confirmed. Hypothesis 3, the “Elshout-Raaheim hypothesis,” predicts that fluid intelligence and problem-solving competence are most strongly correlated in the context of intermediate levels of task-related content knowledge, however the highest correlation was found in the group with low domain-specific knowledge. The findings suggest that intelligence plays a minor role in later stages of competence development whereas typical problem situations in later stages particularly require prior knowledge. The relationship of intelligence, knowledge and problem solving as well as limitations of the study, particularly weaknesses in the measurement of non-cognitive dispositions, are discussed. 相似文献

ABSTRACT In this paper, we explore possibilities and challenges for deliberative academic development. Deliberative academic development refers to a practice that engages members of the university in dialogue about its purposes, ways of organizing and leading higher education, as well as teaching and learning. The paper critically analyses data from focus group interviews with academic developers from four universities within two national contexts. Combining sociological conceptualizations of agency and the framework of ‘epistemic living spaces’, the paper offers insights into challenges and opportunities for deliberative academic development, as well as a framework for studying agency in other contexts. 相似文献

Different indicators are interesting for analyzing human learning processes. Recent studies analyze learning performance in combination with cognitive load, as an indicator for learners’ invested mental effort. In order to compare different measures of cognitive load research, the present study uses three different objective methods and one subjective method, reviewing the seductive details effect in a computer-based multimedia learning instruction. An experimental two-group design (N = 50) was used, with exposure to seductive details during learning as the between group factor. Eye movements were analyzed concerning the indicated cognitive activity and cognitive load was measured by the rhythm method (Park 2010; Park and Brünken 2015), the index of cognitive activity (ICA) (Marshall 2007), as well as by subjective ratings of mental effort and task difficulty (Paas 1992). Results confirm the seductive details effect for learning success with a decrease in retention and comprehension performance, an increase in total cognitive activity indicated by eye movements and significant higher cognitive load, indicated by rhythm method. The ICA values and the subjective ratings on mental effort and task difficulty show no difference in cognitive load between the groups. The results provide evidence of the suitability of different objective measures for a direct and continuous cognitive load assessment in multimedia learning. Further, the results show the benefit of combining different methods to gain detailed insight into information processing while learning with multimedia as well as a differentiated access to the single cognitive load factors. 相似文献

Programmes of international educational exchange are not only carried out for educational purposes, but form an important part of modern-day public diplomacy. Through exchange programmes education and research are linked with foreign policy interests, which then in turn should affect the international contacts of universities and research facilities. The present article applies a long-term perspective on the scholarship programme of the Swedish state in order to show how the shifts in Swedish foreign policy during the period 1938–1990 have affected the number and composition of scholars incoming to Sweden over time. 相似文献

Although owned media formats that pursue brand-policy objectives have been receiving considerable attention in industries since the beginning of the millennium, virtually no research results are available about their conceptual background and strategic management. Using total interpretive structural modeling, this study examines two research questions: (1) Which success factors for the evolving brand-owned media concept can be identified? (2) How can these factors be systematized in terms of interrelations and hierarchies? Results indicate that the success of brand-owned media depends on a complex interrelation of eight factors. Content-centric factors such as content quality and the non-advertising character of brand-owned media are most important for creating relevant content and for achieving media success in terms of reach and frequency. In contrast, brand strength is not regarded as a precondition of brand-owned media success but rather as a result. 相似文献

This article demonstrates how changes in the language of Swedish education policy have opened up a new social perception of education, in which space has been created for new actors, models and solutions in terms of managing activities in schools. Specifically, it seeks to illustrate how various promotion and prevention programmes have been authorized and disseminated without critical inquiry or resistance in the education sector. To this end, we analyse how the specific, essentially contested concepts of health, value base and communication have been employed in authoritative national documents over the two last decades. For our analysis, we draw on speech act theory, with a focus on linguistic performativity, as we have been interested in analysing how concrete authoritative actors have ‘performed’ various arguments. The analysis helps us to understand how the linguistic force originating from authoritative agencies can be used by different actors as a way to legitimize their arguments and actions. The results demonstrate how different national authorities, as a consequence of their use of the three concepts analysed, have contributed to the establishment of promotion and prevention programmes in education. 相似文献
