Mind what mother says: narrative input and theory of mind in typical children and those on the autism spectrum

In 2 studies mothers read wordless storybooks to their preschool-aged children; narratives were analyzed for mental state language. Children's theory-of-mind understanding (ToM) was concurrently assessed. In Study 1, children's (N=30; M age 3 years 9 months) ToM task performance was significantly correlated with mothers' explanatory, causal, and contrastive talk about cognition, but not with mothers' simple mentions of cognition. In Study 2, the same pattern was found in an older sample of typically developing children (N=24; M age 4 years 7 months), whereas for children on the autism spectrum (N=24; M age 6 years 7.5 months), ToM task performance was uniquely correlated with mothers' explanatory, causal, and contrastive talk about emotions.     

支持开放教育资源项目的方法

本文考察了英国教育技术互用性标准中心（CETIS）通过支持国家项目（即英国联合信息系统委员会（JISC）和高等教育委员会的英国开放教育资源试点项目,详见http：／／www．jisc．ae．uk／oer）,以促进发布开放教育资源方面的经验,并探索了如何让我们的支持模式对其他相关项目有所启发,并能改编用于鼓励开放课件运动的可持续性技术支持网络。作为一个涵盖英国众多大学的国家层面的创新举措,众多开放教育资源提供者参与了英国开放教育资源（UKOER）,这包括个别教育者、学科联合体和机构。考虑到这种多样性,从一开始我们就意识到没有任何一种技术解决方案能适合所有的项目。因此,也没有委托专门的工具、描述性标准、交流或分发机制（除要求所有制作的资源应该放在国家学习资源库中外,详见http：／／jorum．ae．uk）。为了支持这一项目,我们引导采取不同的方法和形成不同的社群,也许在支持发布开放教育资源方面,任何类似的跨机构创新都将会面临相似的问题。我们的项目支持方法已从具体的细节问题发展到提供基本的支持原则,从而预测其他问题,并推动最佳实践。我们的做法是：通过会议上的技术汇报和讨论机会,以及在博客上发帖,激发讨论;通过技术评论讨论,并记录针对这些公布在网上的讨论的总结性内容,从而调查个别项目的技术选择;针对通过以上方式所发现的问题,以及项目博客上凸显的问题,做出相应的反馈。考虑到如何使这一方法在更广泛的范围内应用,我们也反思了这种公开的工作模式所面临的挑战、这一方法的开支、适应性,以及我们所认为的其在支持开放教育资源管理和传播方面所扮演的角色。     

Processing of conflicting and redundant stimulus information by pigeons

Selective attention in processing of visual information by pigeons, trained on alternating sessions with two colors (red and green) and two forms (a diamond and an X shape) differentially associated with a left—right key choice task, was examined. A color and a form were presented together on probe trials during sessions in which, on other trials, only one of the dimensions, color or form, was shown. The dimension in effect on the surrounding trials had no influence on choice when the information provided by the two dimensions on probe trials was in conflict—color correct for one choice and form for the other. When both color and form redundantly cued the correct choice, there was no increase in accuracy in comparison with that associated with one dimension. Following separate training on the color and form discriminations, pigeons appeared to base their choices on color on some trials, on form on other trials, but not on both simultaneously. These findings are discussed in terms of an exemplar model of information processing.     

Reforming special education in Scotland: tensions between discourses of professionalism and rights

In 2001, the (then) Scottish Executive embarked on a process of reform of the SEN framework in Scotland. This paper analyses negotiations between different social actors, principally local authority staff and parents, in the formation of the legislation and its subsequent enactment. Data are drawn from an analysis of responses to consultations, official statistics and parent and local authority staff perceptions of the reforms as revealed in questionnaire surveys. It is argued that policy frameworks based on professionalism and bureaucracy have tended to dominate in Scotland, with a rights framework emerging much more recently. The legislation attempts to strike a balance between the different actors, although, in implementing the legislation, local authorities have sought to neutralise aspects which they felt tipped the balance of power too far in favour of parents. Parents have responded by campaigning as citizen‐consumers, and appear to be having a growing influence on Government.     

High‐quality interactions with infants: relationships with early‐childhood practitioners’ interpretations and qualification levels in play and routine contexts

This study investigated factors related to the quality of early‐childhood practitioners’ interactions with infants in play and routine contexts. Participants were 24 practitioners working with 9–20‐month‐old infants in long day‐care infant programmes. Video‐recordings of their interactions with a nominated infant during play and in routine contexts were rated for levels of sensitivity and stimulation. Practitioners were asked to interpret extracts of this video footage and these interpretations were rated according to the complexity of the interpretive narrative. Results indicated relationships between practitioner qualification, their levels of interpretive complexity and the quality of their interactions. The quality of play interactions was significantly higher than that of routine interaction. The implications of these findings in relation to the provision of high‐quality infant day‐care programmes are discussed.     

On the Perceived Quality of Movies

We address the question of the quality of movies produced between 1950 and 1970. A first outcome of our analysis is that the quality assessments made during the Cannes Festival, and to a lesser degree, by the U.S. Academy are short-lasting. In contrast to this, consumers seem consistent over time. There is, however, one issue on which experts agree as well as consumers: American movies dominate both in terms of commercial success and in terms of quality. There is less agreement, and sometimes there is even dissent concerning other dimensions. This does not come as a surprise and merely indicates that there is hardly a common yardstick along which the quality of a movie can be measured. Therefore, decomposing a work of art into quantifiable characteristics – even in a subjective but possibly unanimous way – would make it possible to explain the divergences between audiences and changes of appreciation over time.     

Language, literacy and bilingual education: An amazon people's strategies for cultural maintenance

This paper is concerned with the rights of indigenous peoples to maintain their own languages which are seen as fundamental to the maintenance of their own cultures and for the transmission of culture from one generation to another. Taking the examples of two small neighbouring groups belonging to the Harakmbut Amazon people, it shows that even though their objectives are the same — the maintenance and strengthening of their language and culture — they have very different views about how this should be done. The paper argues that it is necessary to understand the communities' reactions to new proposals for language maintenance introduced from outside and of the importance of them developing and following their own strategies for maintaining their cultural identity in a rapidly changing world.     

The effects of skin and core tissue cooling on oxygenation of the vastus lateralis muscle during walking and running

Skin and core tissue cooling modulates skeletal muscle oxygenation at rest. Whether tissue cooling also influences the skeletal muscle deoxygenation response during exercise is unclear. We evaluated the effects of skin and core tissue cooling on skeletal muscle blood volume and deoxygenation during sustained walking and running. Eleven male participants walked or ran six times on a treadmill for 60 min in ambient temperatures of 22°C (Neutral), 0°C for skin cooling (Cold 1), and at 0°C following a core and skin cooling protocol (Cold 2). Difference between oxy/deoxygenated haemoglobin ([diffHb]: deoxygenation index) and total haemoglobin content ([tHb]: total blood volume) in the vastus lateralis (VL) muscle was measured continuously. During walking, lower [tHb] was observed at 1 min in Cold 1 and Cold 2 vs. Neutral (P?0.05). Lower [diffHb] was seen at 1 and 10 min in Cold 2 vs. Neutral by 13.5 ± 1.2 µM and 15.3 ± 1.4 µM and Cold 1 by 10.4 ± 3.1 µM and 11.1 ± 4.1 µM, respectively (P?0.05). During running, [tHb] was lower in Cold 2 vs. Neutral at 10 min only (P = 0.004). [diffHb] was lower at 1 min in Cold 2 by 11.3 ± 3.1 µM compared to Neutral and by 13.5 ± 2.8 µM compared to Cold 1 (P?0.001). Core tissue cooling, prior to exercise, induced greater deoxygenation of the VL muscle during the early stages of exercise, irrespective of changes in blood volume. Skin cooling alone, however, did not influence deoxygenation of the VL during exercise.     

Some Recent Developments in Teacher Education in Mathematics and Science: A Review and Commentary

Teacher preparation in science and mathematics will be best served, says the author of this roundup, by improvements both in the pedagogy and content of the undergraduate science and mathematics courses required of future teachers and in the reform of required science and mathematics methods courses. In a review of the history and politics of teacher education, the author underscores the twin goals of achieving program coherence and higher standards. She compares the place of mathematics education in mathematics departments with that of science education in science departments and recommends the replacement of bare bones methods courses with those combining pedagogy and content. Included is a selective bibliography.
