Unlike some pivotal ideas in the history of science, the basic notion of natural selection is remarkably simple and so one might expect most students to easily grasp the basic principles of the Darwinian theory; yet many students nevertheless have difficulty understanding Darwinian evolution. We suggest that misconceptions about natural selection arise from mistaken categorization. Our thesis for explaining students’ failure to understand this concept or evolution in general is not that they necessarily fail to understand individual Darwinian principles; rather, they often fail to understand the ontological features of equilibration processes, of which evolution is one instance. They thus attribute the evolutionary process in general, and natural selection in particular, with event‐like properties. For example, naive students appear to focus on the idea of survival of the fittest, but embed this idea within an event ontology that involves actors struggling to overcome obstacles and achieve goals. Results showed that most naive subjects’ evolutionary explanations reflected an event ontology. Furthermore, event ontology attributes were positively correlated with non‐Darwinian explanations; by contrast, equilibration attributes, when present, were positively correlated with key Darwinian principles. These findings suggest that students would greatly benefit from science instruction that emphasized the underlying ontology of modern evolutionary theory. 相似文献

The objective of this study was to describe the anthropometric profiles of elite older triathletes participating in the 2009 Ironman Brazil and to compare their somatotype, anthropometric and body composition characteristics with those of elite young triathletes and older non-athletes. The sample consisted of 64 males, divided into three groups: (1) older triathletes (n = 17), (2) young triathletes (n = 24), and (3) older non-athletes (n = 23). Somatotype was analysed according to the Carter and Heath ( 1990 ) method. Body mass index, sum of four skinfolds, percentage body fat, body fat mass, and fat-free mass were also estimated. Older non-athletes had higher endomorphy, sum of four skinfolds, fat percentage, and body fat mass than the athletes. Older athletes who participated in the Ironman and elite young triathletes had higher fat-free mass than older non-athletes. Older triathletes and older non-athletes were considered mainly endomorphic mesomorphs and young triathletes mainly ectomorphic mesomorphs. The findings that characterize the anthropometric profile of athletes in this sports modality could be used as a reference. 相似文献

Promoting Vocational Development: Methods of Intervention
and Techniques Used in the Italian Context
Laura?NotaEmail author Salvatore?Soresi Scott?H.?Solberg Lea?Ferrari 《International Journal for Educational and Vocational Guidance》2005,5(3):271-279
This article describes a Master Educator Series designed to help educators in Italy design and implement comprehensive vocational guidance curriculum. In this “Master Educator” training, a variety of vocational development models and theories are presented. The goal is to provide a broad range of skills in assessment and intervention strategies to prepare educators for developing the curriculum that best fits their unique context. Five curriculum examples are described. Each of these interventions is built around a vocational development topic, including: providing individualized feedback, improving social relationships and connections, using written exercises, and providing mastery and vicarious experiences. 相似文献

Interindividual Differences in Neonatal Imitation and the Development of Action Chains in Rhesus Macaques 总被引：1，自引：0，他引：1

The capacity to imitate facial gestures is highly variable in rhesus macaques and this variability may be related to differences in specific neurobehavioral patterns of development. This study evaluated the differential neonatal imitative response of 41 macaques in relation to the development of sensory, motor, and cognitive skills throughout the 1st month of life. The results show that infants who imitate facial gestures display more developed skills in goal-directed movements (reaching–grasping and fine hand motor control) than nonimitators. These differences might reflect, at least in part, the differential maturation of motor chains in the parietal and motor cortices, which partly overlap with those of the mirror neuron system. Thus, neonatal imitation appears to be a predictor of future neurobehavioral development. 相似文献

Sports fanship in the contemporary era is increasingly emerging in the virtual space represented by social networks, forums and blogs. This aspect, correlated with the globalization of TV sports broadcasting, conveys a rupture of the traditional fanship connotations, often related to the geographic-familiar context and the local identity, as a primary form of sympathy between a club and its supporters. A relevant aspect of the globalized forms of fanship is represented by groups of supporters who are using the technological communication networks to create original forms of support, which are, in the case of Indonesian Juventus’s supporters, an imitation of the local practices, as chants and banners that characterize the stadium terraces. This article analyses the Indonesian fanship for the Italian football club Juventus which is explicative of the dynamics between local and global, traditional and mediatized forms of fanship and their expressions. 相似文献

The growing field of miniaturized diagnostics is hindered by a lack of pre-analysis treatments that are capable of processing small sample volumes for the detection of low concentration analytes in a high-throughput manner. This letter presents a novel, highly efficient method for the extraction of low-molecular weight (LMW) proteins from biological fluids, represented by a mixture of standard proteins, using integrated microfluidic systems. We bound a polydimethylsiloxane layer patterned with a microfluidic channel onto a well-defined nanoporous silica substrate. Using rapid, pressure-driven fractionation steps, this system utilizes the size-exclusion properties of the silica nanopores to remove high molecular weight proteins while simultaneously isolating and enriching LMW proteins present in the biological sample. The introduction of the microfluidic component offers important advantages such as high reproducibility, a simple user interface, controlled environment, the ability to process small sample volumes, and precise quantification. This solution streamlines high-throughput proteomics research on many fronts and may find broad acceptance and application in clinical diagnostics and point of care detection. 相似文献
