Through interviews and observing day‐to‐day classroom practice, this study explores the beliefs of 10 music teachers in elementary schools in Vancouver and Hong Kong. The results demonstrate that the music teachers of the two localities hold similar cognitive beliefs about the essential elements of music education. However, they hold different beliefs about the value or impact of music education on the psychological or character development of students. Music teachers of Vancouver are found to be more student‐centred than their counterparts in Hong Kong, and this is reflected in both the curriculum and activities selected for classroom teaching. Though both groups of teachers place similar emphasis on western music, in Canada more classroom activities are based around the student’s personal enjoyment and expression. In Hong Kong, meanwhile, music education is viewed as a means of nurturing the student’s temperamental development. While students in Vancouver are allowed to express their personal musical preferences in classroom activities, in Hong Kong students are required to perform according to prescribed standard indicators of success. This is probably linked—albeit invisibly—to Chinese Confucian culture. 相似文献

This study used a survey design (N = 168) to examine how parent and child demographics, parental media-use motives, parental subjective norms, and parental attitudes toward preschool media use (PMU) are all related to actual media exposure among children 6 months to 5 years in age. Results indicate that, in accordance with the theory of reasoned action, parents’ perceived subjective norms regarding various categories of media were significantly related to actual child consumption. Further, positive attitudes toward media were significantly related to higher rates of child consumption. Interestingly, parental worries about media were only negatively related to television consumption and unrelated to child exposure to other kinds of media. 相似文献

Accidents can be intent-based (unintended action-unintended outcome) or belief-based (intended action-unintended outcome). As compared to intent-based accidents, giving reasons is more crucial for belief-based accidents because the transgressor appears to have intentionally transgressed. In Study 1, UK-based preschoolers who were native English speakers (N = 96, 53 girls, collected 2020–2021) witnessed two intent-based or belief-based accidents; one transgressor apologized, the other apologized with a reason. Five-year-olds, but not 4-year-olds, favored the reason-giving transgressor following a belief-based accident but not an intent-based accident (where an apology sufficed). In Study 2, 5-year-olds (N = 48, 25 girls, collected 2021) distinguished between “good” and “bad” reasons for the harm caused. Thus, 5-year-old children recognize when reasons should accompany apologies and account for the quality of these reasons. 相似文献

Primary hemostasis and blood clotting is known to be influenced by the red blood cell volume fraction (hematocrit) in blood. Depressed or elevated levels of red blood cells can lead to vascular perfusion problems ranging from bleeding to thrombus formation. The early stage of hemostasis and thus blood clotting in all vessel sections from the arterial to the venous system involves the adhesion of platelets to von Willebrand factor. Here we present experimental and theoretical results showing that the adhesion probability of platelets to von Willebrand factor is strongly and nonlinearly dependent on hematocrit and flow rate. Interestingly, the actual binding forces are not markedly different, which suggest that the origin of such behavior is in the distribution of platelets. Using hydrodynamic simulations of a simple model, we explicitly show that the higher the hematocrit and the flow rate, the larger the amount of platelets residing close to the wall. Our simulation results, which are in excellent agreement with the experimental observations, explain why such phenomena occur. We believe that the nonhomogeneous red blood cell distribution as well as the shear dependent hydrodynamic interaction is key for the accumulation of platelets on the vessel wall. The work we present here is an important step forward from our earlier work on single molecules and extends into the collective cellular behavior of whole blood. It sheds new light on the correlation between hematocrit and the initial steps in hemostasis and thrombosis, and outlines advances for the treatment of vascular diseases associated with high levels of red blood cells. These results are not only highly relevant for the field of hemostasis and the physics of blood clotting but are also of powerful impact in applied science most obviously in drug delivery and colloidal science. 相似文献

AbstractAs digital natives enter higher education, there is the need to improve their information skills but they often overestimate their information research skills and are unfamiliar with the library. The serious games give the opportunity for innovative and engaging approaches to information literacy learning. The paper describes NAVIGATE - Information Literacy: a Game-based Learning Approach for Avoiding Fake Content, a project funded by Erasmus?+?program. The Project aims to improve the competences to avoid fake content of the higher education students in the Humanities. The paper focuses on the comparative analysis of the students’ skills gap and the difficulty of actually assessing the learning improvement achieved by games, highlighting the lessons learned and the open issues. 相似文献

Ballet training includes exercises of high and moderate intensities, which require breathing control for a good performance. This study describes the thoracoabdominal motion of professional dancers and compares the breathing patterns between professional dancers and non-dancers. Participants of this study were four male and four female (30.33 ± 4.64 years) professional dancers and four male and four female (22.75 ± 1.49 years) non-dancers. The participants executed two breathing manoeuvres while sitting motionless: quiet breathing (QB) and vital capacity (VC). The 3D coordinates of 32 retro-reflective markers positioned on the trunk were used to calculate the volume of the superior thorax, inferior thorax and abdomen. Principal component analysis was applied in the volume variation of each trunk compartment to search for dominant independent variables in a breathing motion pattern. The correlation coefficient was calculated to verify the coordination between the compartments during the breathing manoeuvres. A predominance of the superior thorax or abdomen movement was found in both groups. The professional ballet dancers have an efficient breathing pattern and maintain the same breathing pattern in QB and VC manoeuvres. On the other hand, the non-dancers group showed relevant changes of the breathing pattern to respond to a greater breathing effort, like in VC. 相似文献
