Social contexts shape the development of attention; however, little is known about joint attention beyond infancy. This study employed behavioral and eye-tracking measurements to investigate cultural variations in how caregivers direct 3- to 4-year-old children's attention and subsequent changes in children's attention to objects and contextual backgrounds in the United States (predominantly non-Hispanic Whites) and Japan (N = 60 mother-child dyads, 29 girls, 31 boys). The findings revealed that caregivers directed children's attention to culturally sensitive information, and significant cross-cultural differences in attention emerged after caregiver–child interaction, with Japanese children shifting their attention to the backgrounds. Results provide new insights into the role of social interaction and cultural diversity in the development of attention. 相似文献

It is essential for medical students to learn and comprehend human anatomy in three dimensions (3D). With this in mind, a new system was designed in order to integrate anatomical dissections with diagnostic computed tomography (CT) radiology. Cadavers were scanned by CT scanners, and students then consulted the postmortem CT images during cadaver dissection to gain a better understanding of 3D human anatomy and diagnostic radiology. Students used handheld digital imaging and communications in medicine viewers at the bench‐side (OsiriX on iPod touch or iPad), which enabled “pixel‐to‐tissue” direct comparisons of CT images and cadavers. Students had lectures and workshops on diagnostic radiology, and they completed study assignments where they discussed findings in the anatomy laboratory compared with CT radiology findings. This teaching method for gross and radiological anatomy was used beginning in 2009, and it yielded strongly positive student perspectives and significant improvements in radiology skills in later clinical courses.

Studies to date show how low-fee private (LFP) schools, including unrecognised ones, have gained practical legitimacy and continue to increase in number. However, little explanation is offered regarding the legal legitimacy of such unrecognised LFP schools. This paper intends to fill this gap by examining the legal legitimacy of unrecognised schools in Delhi whose actual existence was challenged by the Delhi High Court and the Right to Education Act, 2009. The paper also illustrates the practical legitimacy of unrecognised schools by comparing perspectives of different actors (the government, NGOs and managers, teachers and parents at nine unrecognised schools in Delhi) based primarily on the author’s interviews with these actors. 相似文献

This study explored the reasons people expose themselves to news depicting tragic events. A total of 376 undergraduates completed anonymous questionnaires about their responses to news coverage of the events of September 11. The study examined the extent to which individual differences in empathy gave rise to news viewing motives (surveillance, reassurance, curiosity), and how these variables, as well as negative emotional responses (anger, sadness, fear), were related to news interest and exposure. Both empathy and emotional responses were associated in predictable ways with interest in news coverage and selective exposure to specific types of news stories (e.g., casualty news, positive news). The results demonstrate that considering affective motivations can enrich our understanding of how and why people use news media. Limitations and suggestions for future research are discussed. 相似文献

Many girls are not sent to school in Yemen, despite basic education being free as well as compulsory for all children aged 6–15. Aiming to improve girls’ enrolment by increasing parental and community involvement, the Japan International Cooperation Agency (JICA) offered a technical cooperation project in June 2005 called Broadening Regional Initiative for Developing Girls’ Education (BRIDGE). Phase 1 of this project ran for three and a half years, piloting a participatory school management model supported by school grants in six districts of the Taiz Governorate in the Southwest of Yemen. To find out how successful this approach has been in a traditional society, the authors of this paper analysed the gender parity index (GPI) of the project’s pilot schools. Based on data collected at three points in time (in the initial and final years of the project, and two years after the project’s end), their findings suggest that interventions in school management which strongly emphasise girls’ education can be effective in improving gender parity rather quickly, regardless of the schools’ initial conditions. However, the authors also observe that the pilot schools’ post-project performance in terms of gender parity is mixed. While the local government allocated budgets for school grants to all pilot schools even after the project’s end, training and monitoring activities were cut back. The authors further observe that the variation in performance appears to be significantly correlated with school leaders’ initial perceptions of gender equality and with the number of female teachers employed. These findings point to the importance of providing schools with continuous long-term guidance and of monitoring those which implement school improvement programmes. 相似文献

We investigated the effects of two types of nonweight-bearing exercise on changes in bone-specific alkaline phosphatase (BAP) and procollagen type 1 C-peptide (PIP). BAP is a specific marker of bone synthesis, whereas P1P reflects synthesis of type 1 collagen in other organs as well as bone. Eight participants performed static and dynamic unilateral knee extensions. BAP and PIP were measured before, and at 1, 2, 24, 48, and 72 hr after exercise. PIP increased at 24 hr after a static knee extension exercise, whereas BAP did not change during the experimental period. We found no changes in these markers after dynamic exercise. These results imply that type I collagen synthesis in tendons increases after static exercise. 相似文献

Since clubface orientation at impact affects ball direction and ball spin, the ability to control clubface orientation is one of the most important skills for golfers. This study presents a new method to describe clubface orientation as a function of the clubshaft motions (i.e., swing plane orientation, clubshaft angle in the swing plane, and clubshaft rolling angle) during a golf swing and investigates the relationships between the clubshaft motions and clubface orientation at impact. The club motion data of driver shots were collected from eight skilled golfers using a three-dimensional motion capture system. The degrees of influence of the clubshaft motions on the clubface orientation were investigated using sensitivity analysis. The sensitivity analysis revealed that the swing plane horizontal angle affected the clubface horizontal angle to an extent of 100%, that the clubshaft angle in the swing plane affected both the clubface vertical and horizontal angles to extents of 74 and 68%, respectively, and that the clubshaft rolling angle affected both the clubface vertical and horizontal angles to extents of -67 and 75%, respectively. Since the method presented here relates clubface orientation to clubshaft motions, it is useful for understanding the clubface control of a golfer. 相似文献

Using a bidimensional two-parameter logistic model, the authors generated data for two groups on a 40-item test. The item parameters were the same for the two groups, but the correlation between the two traits varied between groups. The difference in the trait correlation was directly related to the number of items judged not to be invariant using traditional unidimensional IRT-based unsigned item invariance indexes; the higher trait correlation leads to higher discrimination parameter estimates when a unidimensional IRT model is fit to the multidimensional data. In the most extreme case, when rθ1 θ2 = Ofor one group and r θ1 θ2 = 1.0 for the other group, 33 out of 40 items were identified as not invariant. When using signed indexes, the effect was much smaller. The authors, therefore, suggest a cautious use of IRT-based item invariance indexes when data are potentially multidimensional and groups may vary in the strength of the correlations among traits. 相似文献
