Two studies are reported that used multiple measures of creativity to investigate creativity differences and correlates in arts and science students. The first study examined Divergent Thinking fluency, Self-Rated Creativity and Creative Achievement in matched groups of Art and Science students. Arts students scored higher than Science students on two of the three measures. Regression analysis indicated that the educational domain demographic variable was the most consistent predictor of all three measures of creativity. The second study compared natural science, social science and arts students on two performance and two preference measures of creativity, whilst controlling for the effects of general intelligence. Results indicated only Self-Rated Creativity displayed significant group differences, with the regression analysis suggesting a stronger role of personality variables. The differences between the groups and implications for the measurement of creativity are considered.  相似文献

Thirteen Ph.D. students took part in interviews focussed on the nature of their own learning of mathematics. In analysing these interviews an unexpected category emerged concerning the students awareness of others as having particular types of learning goal. In this paper we explore the three levels which we discerned within this category and link them to the notion of cognitive empathy. We suggest that differences in ones own cognitive style are linked to differences in the ability to empathise with those who have alternative learning goals. We also consider how these two features – cognitive style and cognitive empathy – may come to be linked.  相似文献

Purpose

Metalloproteinases are a key component of the pathogenesis of abdominal hernias. Obesity is considered a risk factor in herniogenesis and hernia recurrence. The aim of this study was to evaluate the serum concentrations of metalloproteinase-2 (MMP-2), MMP-9, MMP-13, and adiponectin in morbidly obese and nonoverweight controls.

Materials and methods

The participants were recruited from among patients undergoing bariatric and non-bariatric surgery and divided into two groups: I (body mass index (BMI)≥35 kg/m2, n=40) and II (BMI<25 kg/m2, n=30). Serum concentrations of MMP-2, MMP-9, MMP-13, and adiponectin were measured using enzyme-linked immunosorbent assay (ELISA).

Results

A statistically significant difference between groups was observed for MMP-2 concentration. The median MMP-9 concentration was higher in the obese group, but the difference was not statistically significant. Median MMP-13 concentrations did not differ between groups. Serum adiponectin concentration was insignificantly higher in the non-obese group.

Conclusions

The elevated serum MMP-2 and MMP-9 concentrations in obese individuals may be related to the higher incidence of incisional hernias in this population.

In developing countries, the trend has been for government to assume gradual control of schools run by religious organisations, while allowing them to retain their religious affiliation. In the Caribbean, the relationship between church and state educational systems has generally been cordial. This is particularly so in Trinidad and Tobago, where almost three quarters of the primary schools are denominational: Roman Catholic, other Christian, Hindu and Muslim. However, a significant proportion of pupils do not adhere to the host faith. Demographic trends and internal migration have disturbed the previous pattern of population, but the most important factor is the influence of the Common Entrance Examination, which controls entry to secondary education. Certain primary schools achieve high pass rates and attract large numbers of applicants from all sectors of society, while School Boards and principals accept over-population and set entry criteria other than religious affiliation. Variation in curricula is limited by recently drafted requirements, the government provides the bulk of school funds, and regularly inspects all schools. Such controls may enable the present government to fulfil its intention of deemphasising the Common Entrance Examination, but it thereby runs the risk of endangering the religious tolerance engendered by the present multidenominational nature of religious schools.
Zusammenfassung In Entwicklungsländern ging das Bestreben der Regierung dahin, allmählich die Kontrolle über die von religiösen Organisationen geführten Schulen zu übernehmen und ihnen dabei ihre religiöse Bindung zu belassen. In der Karibik bestand bisher im allgemeinen ein herzliches Verhätnis zwischen Kirche und staatlichen Erziehungseinrichtungen. Dies gilt besonders für Trinidad und Tobago, wo fast drei Viertel der Grundschulen Konfessionsschulen sind: römisch-katholisch, anderweitig christlich, hinduistisch und moslemisch. Eine große Anzahl von Schülern gehört allerdings nicht der Glaubensrichtung der Schule an. Demografische Trends und Bevölkerungsfluktuation haben frühere Bevölkerungsmuster verändert, aber der wichtigste Punkt ist der Einfluß der allgemeinen Aufnahmeprüfung, die den Eintritt in die weiterführenden Schulen reguliert.Einige Grundschulen haben hohe Erfolgsraten und ziehen dadurch viele Bewerber aus allen Gesellschaftsschichten an, wobei Schulbehörden und Schulleiter eine Überbelegung akzeptieren und andere Aufnahmekriterien als religiöse Zugehörigkeit festsetzen. Änderungsmöglichkeiten im Curriculum sind durch kürzlich herausgegebene Anforderungsrichtlinien eingeschränkt; die Regierung zahlt den größten Teil der Schulmittel und inspiziert regelmäßig alle Schulen. Diese Kontrollen mögen es zwar der gegenwärtigen Regierung ermöglichen, ihre Absicht, die Bedeutung der allgemeinen Aufnahmeprüfung zu schwächen, zu verwirklichen, aber sie riskiert gleichzeitig, die durch die gegenwärtigen multikonfessionellen Religionsschulen ausgelöste religiöse Toleranz zu gefährden.

Résumé Dans les pays en développement, le gouvernement assume habituellement le contrôle continu des écoles régies par les organisations religieuses, tout en leur permettant de conserver leur adhésion religieuse. Aux Caraïbes, la relation entre les systèmes éducatifs publics et religieux est généralement cordiale. C'est particulièrement le cas à Trinité-et-Tobago, où presque les trois quarts des écoles primaires sont des écoles confessionnelles: catholiques romaines, diverses écoles chrétiennes, écoles hindoues et musulmanes. Cependant, un nombre important d'élèves n'adhère pas à la religion de l'école. Les tendances démographiques et la migration interne ont changé l'ancienne structure de la population, mais le facteur majeur reste l'influence de l'Examen général d'entrée, qui réglemente l'entrée dans le secondaire. Certaines écoles primaires ont un taux de réussite élevé et attirent de nombreux candidats issus de tous les secteurs de la société, tandis que les conseils et les directeurs d'écoles acceptent une surpopulation et fixent d'autres critères d'admission que ceux d'appartenance religieuse. La diversité des programmes d'études est limitée par des contraintes mises en place récemment, le gouvernement octroie l'ensemble des crédits à l'éducation et inspecte régulièrement tous les établissements scolaires. Pareils contrôles peuvent permettre au présent gouvernement d'imposer sa volonté pour diminuer l'importance de l'Examen général d'entrée, mails ils risquent en même temps de mettre en danger la tolérance religieuse engendrée aujourd'hui par la nature multiconfessionnelle des écoles religieuses.

Abstract

The aims of this study were to investigate the energy build-up and dissipation mechanisms associated with using an arm swing in submaximal and maximal vertical jumping and to establish the energy benefit of this arm swing. Twenty adult males were asked to perform a series of submaximal and maximal vertical jumps while using an arm swing. Force, motion and electromyographic data were recorded during each performance and used to compute a range of kinematic and kinetic variables, including ankle, knee, hip, shoulder and elbow joint powers and work done. It was found that the energy benefit of using an arm swing appears to be closely related to the maximum kinetic energy of the arms during their downswing, and increases as jump height increases. As jump height increases, energy in the arms is built up by a greater range of motion at the shoulder and greater effort of the shoulder and elbow muscles but, as jump height approaches maximum, these sources are supplemented by energy supplied by the trunk due to its earlier extension in the movement. The kinetic energy developed by the arms is used to increase their potential energy at take-off but also to store and return energy from the lower limbs and to “pull” on the rest of the body. These latter two mechanisms become more important as jump height increases with the pull being the more important of the two. We conclude that an arm swing contributes to jump performance in submaximal as well as maximal jumping but the energy generation and dissipation sources change as performance approaches maximum.  相似文献
