A Cross-cultural Study of the Development of Artistic Talent,Creativity and Giftedness

In this study, examining the relationships among age, culture, training in the fine arts, the technical and aesthetic properties of drawings, and realized artistic giftedness, the researchers intermixed the juvenile drawings executed by critically acclaimed artists with artworks executed by contemporary North American and Chinese North American children. When judges from the North American culture and from the Chinese North American culture, blind to this mix, assessed the drawings, assessments made by the representatives of both cultures were more alike than they were different. Only the North American judges' assessments, however, suggest that the art students' life drawings were more technically and aesthetically successful, and more creative, on the average, than the non-art students' drawings. These judges also gave the juvenilia the highest scores in technical skill and the lowest scores in creativity independent of technical skill and aesthetic success. Conclusions and implications stress the role of technical skill in the development of artistic potential.     

Joint work is not shifted proximally after a long run in rearfoot strike runners

ABSTRACT

Distal-to-proximal redistribution of joint work occurs following exhaustive running in recreational but not competitive runners but the influence of a submaximal run on joint work is unknown. The purpose of this study was to assess if a long submaximal run produces a distal-to-proximal redistribution of positive joint work in well-trained runners. Thirteen rearfoot striking male runners (weekly distance: 72.6 ± 21.2 km) completed five running trials while three-dimensional kinematic and ground reaction force data were collected before and after a long submaximal treadmill run (19 ± 6 km). Joint kinetics were calculated from these data and percent contributions of joint work relative to total lower limb joint work were computed. Moderate reductions in absolute negative ankle work (p = 0.045, Cohen’s d = 0.31), peak plantarflexor torque (p = 0.004, d = 0.34) and, peak negative ankle power (p = 0.005, d = 0.32) were observed following the long run. Positive ankle, knee and hip joint work were unchanged (p < 0.05) following the long run. These findings suggest no proximal shift in positive joint work in well-trained runners after a prolonged run. Runner population, running pace, distance, and relative intensity should be considered when examining changes in joint work following prolonged running.     

Fish Oil Supplementation in Pregnancy and Neurodevelopment in Childhood—A Randomized Clinical Trial

A double-blind randomized controlled trial of n-3 long-chain polyunsaturated fatty acid (n-3 LCPUFA) supplementation or matching placebo during third trimester of pregnancy was conducted within the COPSAC₂₀₁₀ mother-child cohort consisting of 736 women and their children. The objective was to determine if maternal n-3 LCPUFA pregnancy supplementation affects offspring neurodevelopment until 6 years. Neurodevelopment was evaluated in 654 children assessing age of motor milestone achievement, language development, cognitive development, general neurodevelopment, and emotional and behavioral problems. Maternal n-3 LCPUFA supplementation during pregnancy improved early language development and reduced the impact of emotional and behavioral problems. The n-3 LCPUFA supplementation was in boys associated with the earlier achievement of gross motor milestones, improved cognitive development, and a reduced impact of emotional and behavioral problems.     

Giving the invisible hand a helping hand: How ‘Grants Offices’ work to nourish neoliberal researchers

Neoliberalism has become a highly dominating and taken-for-granted way of organising the university sector around the world. In the critical educational literature, this market-based rationality has been scrutinised in detail over the past decades. However, rather scant attention has been directed to how university managers and administrators, apart from setting up quasi-markets, may intervene more directly to give the invisible hand of the market a helping hand. Aiming to address this lacuna, the purpose of the current article is to develop an empirically grounded taxonomy of different types of such interventions, and to theorise them in terms of the different facets of the neoliberal milieu that they reproduce and the various forms of subjectivising work among academics that they seek to engender. We do so by means of a qualitative study of so-called ‘Grants Offices’ at three Swedish universities. The findings arguably add to and problematise our understanding of how neoliberal markets work in academia in three different ways. First, while extant research has noted that university managers and administrators may intervene beyond the setting up of neoliberal markets per se, our study is to our knowledge the first one that identifies and systematises a broad array of such interventions. Second, it problematises the view of neoliberal markets as a form of monolithic entity that produces a uniform competitive pressure on academics. Third, and related, it furthers our understanding of the type of subjectivity that competitive milieus are assumed to bring about.

数学与自然之书数学面对实在的可应用性问题

当今时代，人类差不多生活在数字的漩涡里。数学在时空实在中的可应用性问题，本质上是一个知识论的问题，文章分四个步骤对该问题进行了剖析：先是讨论亚里士多德的数学作为一种抽象的观点，随之讨论柏拉图的数学理念论，继之讨论康德的构造主义纲领，最后讨论维特根斯坦的规则理论。文中作者试图将康德与维特根斯坦的观点结合起来，以发展出一种“规则主义”，从而突破构造主义的限制，为古典数学留块地盘。在文章的最后，作者还指出了数学化的限度。     

No Difference in the Neural Underpinnings of Number and Letter Copying in Children: Bayesian Analysis of Functional Near‐Infrared Spectroscopy Data

It is under debate whether the neural representation of numbers and letters might rely on distinct neural correlates, or on a mostly shared neural network. In the present study, a total of 47 children in fifth grade (Experiment 1) and sixth grade (Experiment 2) simply copied numbers and letters on a touch screen while brain activation changes were recorded by means of functional near‐infrared spectroscopy (fNIRS). fNIRS data of both experiments and a joint analysis revealed that a shared neural network, particularly in the left hemisphere, was activated in response to both number and letter copying. Interestingly, no difference was observed in brain activation patterns between these two stimuli, as revealed by Bayesian analysis. Our findings indicate that both number and letter copying lead to similar brain activation in children. We further suggest methodological and applied applications of these findings in the frame of educational neuroscience.     

Identifying determinants of risk of sexual victimization of youth: a multivariate approach

The present study argues that a greater understanding of the factors which contribute to a youth's sexual victimization is likely to not only be based on what we know about the youths who are victimized but also on comparative information on youths who are not. Selected social background variables from a sample of young victims (n = 20) and nonvictims (n = 21) representing a population of youths with histories of antisocial behavior were compared. Using stepwise discriminant analysis several factors relating to youths' home environment significantly discriminated victims from nonvictims. The results suggest that the probability of being sexually victimized is increased when the home environment is unstable and lacks adequate control over youths' activities. The need for improved research methodologies to achieve better identification of determinants of risk is discussed. Multivariate assessment of social, situational, and personal factors of victims and nonvictims is recommended as a potentially promising approach for improving current rape prevention efforts.     

Science Teachers’ Use of a Concept Map Marking Guide as a Formative Assessment Tool for the Concept of Energy

In this study, we investigated the value of a concept map marking guide as an alternative formative assessment tool for science teachers to adopt for the topic of energy. Eight high school science teachers marked students’ concept maps using an itemized holistic marking guide. Their marking was compared with the researchers’ marking and the scores of a multiple-choice diagnostic test. Statistical analysis revealed that teachers evaluated students’ concept maps consistently, but the concept map scores were only mildly correlated with the multiple-choice test scores. We explored what each assessment method revealed in terms of students’ understanding with one student’s performance as a showcase. Teachers’ views on using the marking guide of concept maps as an assessment tool were also included. We discuss the value of the concept map marking guide as a formative assessment tool for science teachers to create and modify in order to encourage students’ conceptual learning.
