This paper presents a mathematical model of the dynamic interrelationships between education, creativity and happiness based on both theoretical insights and evidence from recent empirical neurological studies. In this context, the results are conditional on an individual’s learning effort and risk‐aversion. Specifically, I focus on two main determinants of creativity (divergent and convergent thinking) and compare two main educational policies (scholarships versus unstructured training) with regard to their impacts on the happiness gained from creativity in the general and healthy population. A test is provided by matching the model’s predictions with the results of recent neuroscience research. Numerical simulations suggested that improving convergent thinking is more important than improving divergent thinking for creativity to generate happiness throughout an individual’s life, provided that both divergent and convergent thinking have been achieved to a sufficiently large degree, and that unstructured training (i.e., extra‐curricular activities) in divergent thinking (e.g., in accounting schools) is necessary to reach wealthier students who have more difficulty learning. In contrast, scholarships or unstructured training in convergent thinking (e.g., in art schools) are necessary to reach students who learn easily but who are less wealthy. 相似文献

Testing is one of the important tasks in any multi-step sport programme. In most ball games, coaches assess motor, physical and technical skills on a regular basis in early stages of talent identification in order to further athletes’ development. The purpose of the study was to investigate anthropometric variables and vertical jump heights as a free throw effectiveness predictor in water-polo players of different age groups. Two hundred and thirty-six young (10–18 years) male water-polo players partitioned into three age groups underwent anthropometric variables’ measures and squat- and countermovement-jump tests, and performed water-polo free throws. Anthropometric variables, vertical jump heights and throw speed – as a proxy for free throw effectiveness – resulted different over age groups. Particularly, throw speed changed from 9.28 to 13.70 m · s?1 (+48%) from younger to older players. A multiple-regression model indicated that body height, squat-jump height and throw time together explain 52% of variance of throw speed. In conclusion, tall height, high lower limb power and throwing quickness appeared to be relevant determinants for effective free throws. Such indications can help coaches during talent identification and development processes, even by means of novel training strategies. Further research is needed over different maturity statuses. 相似文献

AbstractThe Olympic Games of the modern era are powerful global mediated events. Olympic cities receive an overwhelming examination by world media. As the 2016 Olympic host, Rio de Janeiro has been given an enormous amount of attention, both by the international media and researchers who looked at the urban spaces of Rio, the struggles over the hegemony of the city and the social meanings the Olympics bring to the host city’s citizens. However, studies over the historical relationship between Rio, sport and media are rare. This paper addresses the historical uses of the term Olympic by Brazilian media during the late nineteenth and the early twentieth centuries. By looking at the main articles in the newspapers of these periods, we examine the extent to which ideologies over sports have changed the way the Olympics were represented in Brazil’s national imaginary. We demonstrate how the use of expressions associated with the Olympics historically generated a closer appreciation of these events by the public. We also show how political authorities appropriated the Olympics for their own benefit. The paper concludes by asking whether or not the historical lessons from the early Olympic ideas in Brazil have been learned by the 2016 Rio Games organizers. 相似文献

The present study examined the interplay between self-determined motivation and the use of cognitive strategies in predicting university students’ academic performance while taking into account the effect of prior achievement. A theory based model was tested using structural equation modeling on a sample of 764 Italian university students. Results showed that prior achievement influenced students’ academic performance and their motivation and use of cognitive strategies. Critical thinking was the only cognitive strategy which proved to have a significant impact on students’ academic performance. Autonomous motivation had an indirect positive impact on academic performance through its influence on the critical thinking strategy. Controlled motivation had a direct negative impact on academic performance. On the whole, our findings suggest that autonomously motivated students tend to achieve better academic performance by using critical thinking, while students who are driven by controlled motivation have lower academic performance. 相似文献

This study aimed to evaluate the effect of simulated training strategies on performance potential in elite short-track speed skaters. Training load and field-based criterion performances from fifteen athletes (10 males, 5 females) were collected over a 3-month training period and the relationship between training loads and performance was computed with a variable dose-response model using a genetic algorithm. Individual simulations of tapers preceded or not preceded by an overload training (OT) were assessed. We obtained a significant correlation between actual and modelled performances (R2 = 0.76 ± 0.07). Regarding model parameters, no significant difference was found between males and females but the time to recover performance tended to be lower in females. Simulations in which the taper parameters were free highlighted that an exponential or a step taper were the most effective for increasing performance compared to a linear taper (p < 0.05). Optimal exponential taper duration after OT was 10.7 ± 2.4d and the optimal load reduction was 75.9 ± 3.7%. OT intensity had the greatest influence on the predicted performance, followed by OT duration, taper decay, and to a lesser extent load reduction during taper and taper duration. Thus, a variable dose-response systems model allows the evaluation of different taper strategies and their potential effect on performance changes. 相似文献

Two mechanisms have been suggested to explain stretching-induced maximum force depression: a mechanical alteration in the stretched muscle and an impairment of neural activation. Electrical stimulation allows standardization of the level of muscle activation without being limited by neural control. The aim of this study was to evaluate the stretching-induced changes in the electrical and mechanical properties of muscle during electrically elicited contractions. Twelve participants (age 22 +/- 1 years; body mass 75 +/- 2 kg; stature 1.79 +/- 0.02 m; mean +/- standard error) underwent six electrical stimulations of the medial gastrocnemius muscle before and after stretching. During the contractions, surface electromyogram (EMG) and mechanomyogram (MMG) were recorded simultaneously together with force. After stretching we found: (i) no differences in EMG parameters; (ii) MMG amplitude decreased by 4 +/- 1% (P < 0.05); and (iii) the peak force, the peak rate of force development, and the acceleration peak of force development decreased by 12 +/- 3%, 14 +/- 1%, and 24 +/- 5%, respectively (P < 0.05). In conclusion, acute passive stretching did not change EMG properties but altered the mechanical characteristics of the contracting muscle. Indeed, muscle force-generating capacity and stiffness of the muscle-tendon unit were significantly impaired. 相似文献

In classic Information Retrieval systems a relevant document will not be retrieved in response to a query if the document and query representations do not share at least one term. This problem, known as term mismatch, has been recognised for a long time by the Information Retrieval community and a number of possible solutions have been proposed. Here I present a preliminary investigation into a new class of retrieval models that attempt to solve the term mismatch problem by exploiting complete or partial knowledge of term similarity in the term space. The use of term similarity enables to enhance classic retrieval models by taking into account non-matching terms. The theoretical advantages and drawbacks of these models are presented and compared with other models tackling the same problem. A preliminary experimental investigation into the performance gain achieved by exploiting term similarity with the proposed models is presented and discussed. 相似文献

This article explores the entanglement of gender, education and empire in Bosnia and Herzegovina during the Habsburg period throughout the analysis of a unique institution: Sarajevo’s Muslim Female School. Established at the very end of the nineteenth century, this pedagogical institution was the only school in Austria-Hungary specifically devoted to Muslim girls. The article begins by presenting the development of the Habsburg Empire’s educational policy in Bosnia after 1878 and demonstrates that it was deeply bound with its imperial ‘civilising mission’. Through an analysis of the programmes taught at Sarajevo’s Muslim Female School, the article detects the model of ‘Hapsburg Muslim femininity’ promoted by this institution. By investigating the reports the teachers sent to the authorities, it explores how this school was perceived by the Muslim population. The last section is devoted to the schoolgirls’ experience of this school, and especially to their access to the written word. 相似文献
