The article reconstructs the image of Turkey and the Turks that German education portrayed between 1820 and 1930. The analysis is based on educational periodicals and reference works from the historical eras of the German Confederation, the German Empire and the First World War, tracing the way old stereotypes persisted and new stereotypes arose. The study especially focuses on the opinions of German educationalists about schools in Turkey, Turkish women, Islam, the question of whether Turkey was part of Europe, and last not least on whether Ottoman educational policies were appropriate. Closely following the historical sources, the article shows how the opinions of German educationists changed according to the shift of Germany’s geopolitical interests, how their outlook went hand in hand with the views of the general press, and how they gradually came to a professional self-concept that contrasted ‘their’ educational system with what they believed was a ‘backward’ system in Turkey. At the same time they began to develop an interest in doing professional work in Turkey. The article can also be regarded as a contribution to the history of educational thinking in Germany in the course of the nineteenth century. 相似文献

The aim of this study was to determine the match activity and physiological demands of women's tennis during a 3-day clay-court tennis tournament. The activity profile of eight players was determined by filming each competitive match with video cameras. Metabolic-perceptual measurements--blood samples and individual ratings of perceived exertion (RPE)--were taken while the players were sitting during permitted changeover breaks in play. The activity profile of the players was as follows: strokes per rally, 2.5 +/- 1.6; rally duration, 7.2 +/- 5.2 s; rest time between rallies, 15.5 +/- 7.3 s; effective playing time, 21.6 +/- 6.1%; work-to-rest ratio, 1:2.1. Blood lactate concentration [2.2 +/- 0.9 mmol x l(-1) (n = 50) vs. 2.2 +/- 0.7 mmol x l(-1) (n = 48)] and RPE values [12.2 +/- 2.4 (n = 57) vs. 12 +/- 2.3 (n = 57)] were not significantly different (P = 0.65-0.78) between service and return games. The results highlight the importance of taking these factors (i.e. activity patterns and physiological profile) into account when planning training strategies for competitive females players. As such, tennis training regimes should be adapted to the specific demands imposed by match-play in female players on a clay-court surface. 相似文献

Juvenile obesity is increasing worldwide. Preventive strategies are warranted. The school-based Children's Health Interventional Trial (the CHILT Project) combines health education and physical activity for children. The effect on obesity and physical performance was studied after four years in 12 primary schools compared with five control schools. Anthropometric data were recorded. Physical performance was measured by a coordination test for children (balancing backwards, one-legged obstacle jumping, lateral jumping, sideways movements) and a 6-min run (endurance). No difference in the prevalence and incidence of overweight and obesity was found between the intervention and control schools before and after the intervention. Remission of overweight was higher in the intervention schools (23.2 vs. 19.2%), but not significant. An increase in coordination related to lateral jumping and balancing backwards was apparent in the intervention schools (30.6, s = 10.8 vs. 26.1, s = 10.8, P = 0.005; 21.8, s = 11.8 vs. 19.4, s = 11.7, P = 0.007), and the increase in endurance performance tended to be higher in intervention schools (100.8, s = 122.7 vs. 92.8, s = 126.0, P = 0.055), adjusted for age, sex, baseline test result, and body mass index at final examination. Therefore, preventive intervention in primary school offers the possibility to improve physical performance in children. The prevalence and incidence of obesity were not affected. 相似文献

Abstract The 'stiffness' concept originates from Hooke's law which states that the force required to deform an object is related to a spring constant and the distance that object is deformed. Research into stiffness in the human body is undergoing unprecedented popularity; possibly because stiffness has been associated with sporting performance and some lower limb injuries. However, some inconsistencies surrounding stiffness measurement exists bringing into question the integrity of some research related to stiffness. The aim of this study was to review literature which describes how vertical, leg and knee stiffness has been measured in adult populations while running, jumping or hopping. A search of the entire MEDLINE, PubMed and SPORTDiscus databases and an iterative reference check was performed. Sixty-seven articles were retrieved; 21 measured vertical stiffness, 51 measured leg stiffness, and 22 measured knee stiffness. Thus, some studies measured several 'types' of stiffness. Vertical stiffness was typically the quotient of ground reaction force and centre of mass displacement. For leg stiffness it was and change in leg length, and for the knee it was the quotient of knee joint moments and change in joint angle. Sample size issues and measurement techniques were identified as limitations to current research. 相似文献

The purpose of this conceptual paper is to analyze the potential for collaborative relationships in schools in Ukraine. In this paper, I examine the nature of teacher collaboration in schools within a framework of postmodernism as a constructive social theory. To better grasp the deep meaning of collaborative interactions in schools, I use cultural and micropolitical perspective. Further, I turn to the discussion of the potential for collaboration in Ukrainian schools, utilizing the notion of a collective that prevailed in Soviet society and system of education. Implications for establishing collaborative school cultures in Ukraine conclude the paper. 相似文献

Military service is acknowledged as one of many elements voters use to evaluate candidates, but it has primarily been studied as a univariate element of a candidate’s biography. This project experimentally manipulates veteran status, gender, and partisanship as potentially interactive heuristics for evaluation of a hypothetical candidate specifically regarding military issues. We found an almost universal benefit enjoyed by veterans over civilians regardless of whether the candidate was a member of the participant’s partisan ingroup or outgroup. We also found little evidence of a gender penalty, and even a benefit for women candidates who were veterans, though this benefit was restricted to evaluations from Republican women. We also found that Democratic respondents assigned a penalty to outgroup veteran men candidates. We explain these nuanced findings in the context of moderation by gender mis/alignment between participant and candidate. Implications of the study are offered. 相似文献

This study examines the perceptions of an interaction partner’s physical attractiveness and traits in relation to whether and how partners were evaluated prior to interacting. Sixty-five pairs of heterosexual strangers were randomly assigned to one of three conditions (i.e., prerate photos of opposite-sex strangers including conversation partner, prerate photos excluding partner, no prerate photos). Participants then had a 10-minute interaction, reported impressions of partner, and rated photos again including the partner. Compared to no preinteraction rating, rating conversation partners’ attractiveness reduced impressions of partners’ social attractiveness, fun/funniness, and charisma. Partner impressions were more strongly associated with postinteraction attractiveness ratings than preinteraction ratings. Impressions of social attractiveness and fun/funniness moderated attractiveness rating change, wherein less attractive partners showed more positive change than attractive partners. 相似文献

Penalty takers in association football adopt either a keeper-independent or a keeper-dependent strategy, with the benefits of the keeper-independent strategy presumed to be greater. Yet, despite its relevance for research and practitioners, thus far no method for identifying penalty kick strategies has been available. To develop a validated and reliable method, Experiment 1 assessed characteristics that observers should use to distinguish the two strategies. We asked participants to rate 12 characteristics of pre-recorded clips of kicks of penalty takers that used either a keeper-independent or keeper-dependent strategy. A logistic regression model identified three variables (attention to the goalkeeper, run-up fluency and kicking technique) that in combination predicted kick strategy in 92% of the penalties. We used the model in Experiment 2 to analyse prevalence and efficacy of both the strategies for penalty kicks in penalty shoot-outs during FIFA World Cups (1986–2010) and UEFA Football Championships (1984–2012). The keeper-independent strategy was used much more frequently (i.e., 78–86%) than the keeper-dependent strategy, but successes did not differ. Penalty takers should use both the strategies to be less predictable. Goalkeepers can use the developed model to improve their chances to succeed by adjusting their behaviour to penalty takers’ preferred penalty kick strategy. 相似文献

This study compared accuracy of energy expenditure (EE) prediction models from accelerometer data collected in structured and simulated free-living settings. Twenty-four adults (mean age 45.8 years, 50% female) performed two sessions of 11 to 21 activities, wearing four ActiGraph GT9X Link activity monitors (right hip, ankle, both wrists) and a metabolic analyzer (EE criterion). Visit 1 (V1) involved structured, 5-min activities dictated by researchers; Visit 2 (V2) allowed participants activity choice and duration (simulated free-living). EE prediction models were developed incorporating data from one setting (V1/V2; V2/V2) or both settings (V1V2/V2). The V1V2/V2 method had the lowest root mean square error (RMSE) for EE prediction (1.04–1.23 vs. 1.10–1.34 METs for V1/V2, V2/V2), and the ankle-worn accelerometer had the lowest RMSE of all accelerometers (1.04–1.18 vs. 1.17–1.34 METs for other placements). The ankle-worn accelerometer and associated EE prediction models developed using data from both structured and simulated free-living settings should be considered for optimal EE prediction accuracy. 相似文献
