The purpose of this study was to build a flexible mechanical system with a hydrostatic skeleton. The main components of this system are two type flexible bags. One is a structural bag with constant inner pressure. The other is an actuator bag with controlled inner pressure. To design the system, it was necessary to estimate both structural deformation and driving force. Nu- merical analysis of flexible bags, however, is difficult because of large nonlinear deformation. This study analyzed structural strength and driving force of flexible bags with the nonlinear finite element analysis （FEA） software ABAQUS. The stress con- centration dependency on the bag shape is described and the driving force is calculated to include the large deformation. From the analytical results, this study derives an empirical equation of driving force. The validity of the equation was confirmed by condition-changed analyses and experimental results. 相似文献

Research Findings: The purpose of this study was to examine differences in the development of conflict management strategies, focusing on 3- and 5-year-olds, through a comparison of 3 neighboring Asian cultures, those of China (n = 114), Japan (n = 98), and Korea (n = 90). The dual concern model of conflict management was adopted to probe which strategy children would prefer to use in 2 hypothetical conflict situations. Results indicated that, first, for disagreement, 3-year-olds in the 3 countries equally preferred the dominating strategy. For competition for resources, 3-year-olds differed in their strategy preference across all cultures. Second, the observed strategy preference of 3- to 5-year-old children in this study was more or less different from that of older schoolchildren, regardless of culture. Practice or Policy: These findings suggest the significance of the context, the complexity of the phenomenon of the development of cultural differences, and the significance of cohort sampling. 相似文献

This meta-analysis was conducted to estimate the magnitude of gender difference in three-dimensional (3-D) mental rotation ability and to investigate how factors related to test administration conditions play a role in varying gender difference effect sizes and threatening validity. Individuals’ 3-D mental rotation ability was measured by the Purdue Spatial Visualization Tests: Visualization of Rotations (PSVT:R). We integrated 70 effect sizes of gender differences in mental rotation ability measured by the PSVT:R which were obtained from 40 primary studies. The results indicated that male participants outperformed females on the test (Hedges’ g?=?0.57). The I 2 statistic indicated 41.7 % of variation in effect sizes reflects real heterogeneity. The moderator analysis indicated that male superiority on spatial ability tasks measured by the PSVT:R is related to the implementation of time limits. The gender difference became larger when stringent time limits (equal or less than 30 s per item) were implemented. 相似文献

Educating students with mild disabilities in general education classrooms: Minnesota alternatives 总被引：1，自引：0，他引：1
This article reports two major data collection efforts conducted during successive years. Study 1 examined the relationship between the school effectiveness variables identified in the Minnesota Educational Effectiveness Project (MEEP), and the attitudes and achievement of students in 31 MEEP schools. Study 2, which focused on 11 of the Study 1 schools, compared the instructional programs provided to students with mild disabilities in three integrated programs in these 11 schools, with those provided by conventional resource "pull-out" programs in three other schools. We not only contrasted program characteristics, but analyzed differences between program characteristics and cognitive and affective outcomes. Results do not provide a strong basis for concluding that general efforts at school improvement will provide the framework for improved outcomes among low-achieving students. 相似文献

Faces Do Not Capture Special Attention in Children With Autism Spectrum Disorder: A Change Blindness Study 总被引：1，自引：0，他引：1

Two experiments investigated attention of children with autism spectrum disorder (ASD) to faces and objects. In both experiments, children (7- to 15-year-olds) detected the difference between 2 visual scenes. Results in Experiment 1 revealed that typically developing children ( n = 16) detected the change in faces faster than in objects, whereas children with ASD ( n = 16) were equally fast in detecting changes in faces and objects. These results were replicated in Experiment 2 ( n = 16 in children with ASD and 22 in typically developing children), which does not require face recognition skill. Results suggest that children with ASD lack an attentional bias toward others' faces, which could contribute to their atypical social orienting. 相似文献

A progenitor article for this work can be found in Public Library Quarterly 27, no. 4. This study is the first to report on the types of contents in children's web pages and the characteristics of Web-OPACs for children in public library websites in Japan. This study reveals that children's web pages, in general, place more emphasis on providing guidance on library services and on the use of information resources for reference services, rather than on helping children with regular learning or providing research assistance to adults on children's services. Other findings are reported as well. 相似文献

Measures of socioeconomic status (SES) are routinely used in analyses of achievement data to increase statistical power, statistically control for the effects of SES, and enhance causality arguments under the premise that the SES-achievement relationship is moderate to strong. Empirical evidence characterizing the strength of the SES-achievement relationship and its moderators suggests that this relationship is surprisingly modest, with an average SES-achievement correlation of .22, although it appears to have strengthened in the past 3 decades. The modest SES-achievement relationship has important implications for using SES measures in educational data analyses. We provide evidence of this relationship and of the need to use theoretical models to guide the construction and selection of SES measures in analyses of achievement data. 相似文献
