The on-going Coronavirus disease(COVID-19)outbreak in China has become the world's leading health headline and is causing major panic and public concerns.On January 30,2020,the World Health Organization(WHO)declared that the new coronavirus outbreak is a public health emergency of international concern.1 The virus has already had a direct impact on more than 10 million people in the city of Wuhan and has reached other parts of China as well,posing a health threat of unknown magnitude globally.As of February 8,2020,WHO reported 34,886 confirmed cases of COVID-19 globally,with 34,589 of them occurring in China(including 6101 severe cases and 723 deaths).A total of 288 other confirmed cases(with 1 death)have been reported in 24 countries,including Japan,Australia,Germany,and United States.2 However,these daily estimates are expected to rise even higher as reports from health authorities in China3 are gathered and near real-time updates of the Johns Hopkins virus dashboard are made 4 The outbreak has caused governments in various countries to take swift and protective measures.In China,these included putting cities on lockdown,5 implementing travel wamings/bans and cancellations,6 extending national holidays,and closing schools and postponing classes7. 相似文献

Although there have been a number of studies that compared the test results of the Wide Range Achievement Test (WRAT) and the Peabody Individual Achievement Test (PIAT), none had been accomplished with a group of college-aged learning disabled students. Indeed, few researchers had investigated populations over 16 years of age, and none had compared grade scores and standard scores with appropriate subtest scores as derived from these two instruments. With the recent emphasis on postsecondary education for the learning disabled, it is deemed critical that researchers should develop a data base for study of this population. The current research demonstrated that although both tests purport to measure academic achievement in reading, spelling, and arthmetic, in reality, significantly different scores are derived when WRAT (1965, 1978) norms are compared to PIAT (1970) norms as stated in grade scores and standard scores. These significant differences in the grade and standard scores clearly indicate that the WRAT and the PIAT, particularly in regard to arthmetic and to a lesser degree to reading, are not interchangeable instruments of academic achievement. 相似文献

This study identifies how the contextual features of an elementary school setting shaped and often restricted bilingual kindergarten students' access to friendships within their grade-level English-dominant classroom. Data demonstrate how students utilized a teacher-designed lunch card routine to initiate, maintain, and display friendships in addition to indicating their lunch selection. Findings from the study prompted changes in my instructional practices as well as in the ESL and bilingual program design at the school in order to allow greater interaction between native English and native Spanish speakers. Implications of these findings include the significance of social relationships for language learning, for gaining status, and for motivating bilingual students to remain in school over the course of their K-12 education. 相似文献

Desalination is a relatively new intervention in the field of conservation of architectural heritage. Especially the desalination of immovable objects, such as masonry structures, is still a trial-error practice. In the field, different desalination materials and methods are used, sometimes with unsatisfactory results. Better understanding of the desalination process is needed in order to support the conservator with clear guidelines for choosing a suitable desalination material and method. The research presented in this paper constitutes the first step towards the development of a modular system of poultices, which can be adapted, i.e. fine-tuned to different types of substrates. Starting point is to make use of advection, i.e. the transport of salt ions with water flow. This transport mechanism is faster than diffusion and the application on immovable objects is relatively easy. In order to optimize salt extraction, a poultice working by advection should have smaller pores than the substrate. Starting from this principle the pore sizes of different desalination materials (sand, cellulose, kaolin and bentonite) mixed in different proportions, have been measured. Interesting results were obtained, showing that the desalination materials commonly used in the field are often not the most suitable ones. On the basis of the results, recipes for poultices, adapted to a specific substrate, can be formulated. 相似文献

Results of the Vocabulary, Reading Comprehension, and Mathematics Concepts subtests for third-, sixth-, and eighth-grade students who took Form 5 of the Iowa Tests of Basic Skills in the 1976 school year were analyzed for sex bias. Statistical significance was found for each subtest for all of the grade levels. Follow-up analyses considered skill classification, sex-stereotypicalness, and item location of the items contributing to the statistical significance. No trends for these factors were found within each grade level for the four subtests considered. For all subtests, fewer items are identified at the third-grade level than for sixth or eighth grade, and these items, in general, favored boys. For the older students, when items are found to function differently for boys and girls, nearly half favor each sex. On the whole, little evidence for sex bias was found for the four subtests and three grade levels examined. 相似文献

A sample of 63 gifted elementary-school students was administered the Bender Visual-Motor Gestalt Test and the Developmental Test of Visual-Motor Integration for comparative purposes and to test Koppitz hypothesis that gifted students have advanced visual-motor development. Group results revealed no significant differences between the two tests, that they did correlate significantly, and that younger students in particular had advanced visual-motor development when tested using these two tools. 相似文献

The value of a non-sport-specific motor test battery in predicting performance in young female gymnasts 总被引:1,自引:2,他引:1

Gymnastics talent identification focuses on the identification of young gymnasts who display characteristics for potential success in the future. The aim of this study was to identify which current performance characteristics are related to performance in competition 2 years later. Twenty-three female gymnasts aged 7-8 years completed a multidimensional test battery measuring anthropometric, physical, and coordinative characteristics and were technically evaluated by expert coaches. Two years later, the all-around competition results of those gymnasts now participating in elite (n = 12) and sub-elite (n = 11) competition were obtained. None of the initial measurements significantly correlated with the results of the sub-elite gymnasts 2 years later. For the elite gymnasts, a non-sport-specific motor test battery correlated strongly with the competition result, with more than 40% of the variation in competition performance being explained by the result on that test 2 years earlier. Neither the coaches' judgement nor the anthropometric and physical characteristics were sensitive enough to predict performance. A motor coordination test might be valuable in the early identification of gymnasts, as its discriminative and predictive qualities might be sufficiently powerful for selection within a relatively homogeneous population of gymnasts exhibiting similar anthropometric and physical profiles. 相似文献

Conclusion As you can see, this is a rather holistic view. These categories may have to be expanded depending on the particular needs
of your task. However, it seemed to be efficient. This process may also be applicable to other situations such as student
papers. This was my attempt to compare texts with a minimal amount of bias. I welcome input of others in an effort to expand
and refine this rubric. 相似文献

The City of Richgate project worked with eight intergenerational immigrant families and examined immigrant experiences and narratives through a community‐engaged process that employed a/r/tography as a methodology. As such, the research also investigated the extent to which a/r/tographical research could visually and narratively portray the analysis of data collected by the co‐a/r/tographers. After interviewing and collecting images from each family, large artistic gates (banners) were created. This first phase of the project revealed the power of images in situ, and thus the power of a/r/tography in situ. For the community members and co‐a/r/tographers meanings were constructed within ongoing a/r/tographic inquiries described as collective artistic and educational praxis. The second phase involved the identification of important places by each family within the City of Richmond. After analysing all of the data, several works of art were created with each family in mind: bus shelter images juxtaposing close‐up and far away geographical images; side‐by‐side images portraying historical and contemporary images of family ideals and/or issues; banners illustrating families in meaningful poses; and archival collections portraying the importance of identity and memory in the transformation of culture. This phase culminated in a citywide exhibition of the artwork performing public pedagogy. The exhibition questioned the idea of a City of Richmond having a community centre, and instead exhibited many Richgates, or conceptions of Richmond. Rather than having a city centre, there are many centres, a Network of Cities of Richgates, where centres are constantly changing and shifting to reflect the narratives of individuals living in a psycho‐geographical region of a city. 相似文献

It is well established that working memory is related to reading comprehension ability. However, its role in explaining specific reading comprehension difficulties is still under debate: the issue mainly concerns whether the contribution of working memory is dependent on task modality (verbal tasks being more predictive than visuo-spatial tasks) and/or on the attentional control implied in working memory tasks (tasks requiring storage/manipulation being more predictive than storage-only tasks, regardless of task modality). Meta-analysis is used here to examine the relevance of several working memory measures in distinguishing between the performance of poor and good comprehenders in relation to the modality of the working memory task, and the involvement of controlled attention required by such a task. Our results demonstrate that memory tasks that are demanding in terms of attentional control and that require verbal information processing are best at distinguishing between poor and good comprehenders, suggesting that both domain-specific factors as well as general factors of working memory contribute to reading comprehension performance. The implications for different models of working memory in relation to reading comprehension are discussed. 相似文献
