This review examines the psychological benefits exercise is connected to in healthy children and adolescents. Studies on the effect of exercise on academic performance, self-esteem, emotions, and mood were examined. Academic performance is found to be maintained when normal academic classes are reduced and replaced by an increase in exercise, physical activity, or physical education. Exercise seems to have a positive effect on several aspects of cognition and self-esteem in healthy children and adolescents. A positive connection between exercise and emotions and moods in children is found in the few studies that have been conducted. 相似文献

Wimmer and Goswami (1994) report that seven-, eight-, and nine-year old English children had considerably more difficulties with a nonword reading task than German children who acquire an orthography with highly consistent grapheme-phoneme correspondences. In Study 1, seven-, eight-, and nine year old English children receiving a phonics instruction were presented with the same task and compared with the children tested by Wimmer and Goswami. Study 2 is a replication with different samples of English children receiving the standard electic approach combining both whole-word and phonics strategies, English children receiving a phonics teaching approach and German children who are taught via phonics methods and acquire a consistent orthography. Children from Grades 1 to 4 were tested. In both studies, the English phonics children read the nonwords with almost the aame accuracy and speed as the German children. In Study 1, the English phonics children performed clearly better on nonword reading than the English standard sample. In Study 2, this difference was also evident but less marked. In Grade 1 English phonics as well as English standard children had clearly more difficulties with phonological decoding than German children indicating a relevant influence of orthographic consistency. 相似文献

Previous governments and other commentators have emphasized the relationship between a teacher's knowledge of the subject material being taught and the quality of learning outcomes. This has been reflected in the entry requirements to Initial Teacher Training (ITT) (primary) of public examination performance in the core subjects. However, disquiet has been expressed as to the efficacy of such qualifications as indicators of knowledge and skills at the entry point. Recent changes to ITT (primary) regulations require students' actual knowledge of the content of the three core subjects to be audited. This paper reports and reflects on the effects that re-examining their knowledge and skills in mathematics has had on the confidence of primary trainee teachers. It presents some key questions that must be addressed if the current audit regulations are indeed to benefit our future teachers and to enhance the learning of our pupils. 相似文献

Artworks are an inseparable part of the cultural heritage of societies and provide us with a unique look at cultural developments through time and space. For the best possible conservation, it is paramount to know the constituent materials, condition, and construction techniques of the objects (e.g. painting on wood, fresco, sculpture). Such information is required not only for the surfaces of the objects, but also for the interiors; in the imaging discipline, this is known as depth imaging. Here, we introduce a new method for non-invasive depth imaging as an alternative to traditional non-invasive methods when the latter cannot be used to obtain the required information. We use ultrasonic transverse-wave transmission measurements and turn them into virtual reflection measurements. We achieve this by applying seismic interferometry with active sources. Obtaining reflection measurements by seismic interferometry allows us to apply an advanced imaging technique – prestack depth migration, as used in seismic exploration – to produce a high-resolution depth image of an object. We apply our method to ultrasonic data recorded on a mockup of a painting on a wooden support. We validate our method by comparing our results with an image from X-ray computed tomography. 相似文献

This article explores health journalists’ sourcing patterns in the Dutch-speaking part of Belgium across a range of different media including newspapers, magazines, radio, television and online health news websites. A cross-sectional quantitative content analysis of health news items collected in February 2015 (N?=?981) was established to examine the number and origin (e.g. industry, citizens, experts) of sources (N?=?1998) mentioned in health news stories with particular attention paid to differences across various media types. Despite recent claims of media convergence, cross-media comparisons are scarce and, for a specialized beat such as health, nonexistent. The key findings of this study indicate that ordinary citizens and academic experts constitute the two largest source categories. The small share of industry-related sources confirms journalists’ skeptical attitude towards content provided by the industry. But on closer inspection, large differences can be observed across various media types. On the one hand, ordinary citizens occur with relatively high frequency on television but hardly make an appearance in online news items. Academic sources, on the other hand, are dominant online but nearly absent in television news items. In sum, this analysis demonstrates that health journalists’ source uses differ across various media platforms. 相似文献

The purpose of this article is to compare accuracy of activity type prediction models for accelerometers worn on the hip, wrists, and thigh. Forty-four adults performed sedentary, ambulatory, lifestyle, and exercise activities (14 total, 10 categories) for 3–10 minutes each in a 90-minute semi-structured laboratory protocol. Artificial neural networks (ANNs) were developed for four accelerometers (right hip, both wrists, and right thigh,) to predict individual activities and activity categories, with direct observation (DO) as criterion. The wrist-mounted accelerometers achieved the highest accuracy for individual activities (80.9%–81.1%) and activity categories (86.6%–86.7%); accuracy was not different between wrists. The hip-mounted accelerometer had the lowest accuracy (66.2% individual activities, 72.5% activity categories); thigh-mounted accelerometer accuracy (71.4% individual activities, 84.0% activity categories) fell between the wrist- and hip-mounted accelerometers. ANNs developed for accelerometers worn on the wrists and thigh provided high accuracy for activity type prediction and represent a potential approach to physical activity (PA) assessment. 相似文献

1 When Becky Rohrer rescued an abandoned wreck of a house and lovingly transformed it into a cozy inn, she ended up healing her life as well. Emotionally and spiritually, the distance she's traveled from the life she once lived to where she is today seems almost impossible to measure.…… 相似文献

In this paper, we investigate the question of what assessment tools are being used in practice by United States computing programs and what the faculty doing the assessment think of the tools they use. After presenting some background with regard to the design, implementation, and use of assessment, with particular attention to assessment tools, we report on the results of two surveys, distributed to the SIGCSE mailing list and to the chairs of all ABET-CAC accredited computer science programs. This combination of community practice and advice for non-experts could be helpful to someone designing, evaluating, or improving an assessment plan. 相似文献
