This study examined patterns of close relationships among school‐age children with learning disabilities (LD) as manifested in their attachment style, their self‐perceived loneliness, their sense of coherence, and teacher ratings of their academic functioning. In line with resilience theory, this study also aimed to further explore predictors of positive adjustment for children with LD. The sample comprised 98 children with LD from regular classes in four Israeli public elementary schools, and 98 non‐LD children from the same classes. Significant group differences emerged in attachment styles and adjustment. Attachment style significantly correlated with socioemotional adjustment but not with academic functioning. In addition, a subgroup of resilient children emerged among the LD children. Discussion focused on the value of attachment patterns for understanding social and emotional adjustment among school‐age children with LD. 相似文献

During a visual rhyming task, deaf participants traditionally perform more poorly than hearing participants in making rhyme judgements for written words in which the rhyme and the spelling pattern are incongruent (e.g. hair/bear). It has been suggested that deaf participants’ low accuracy results from their tendency to rely on orthographic similarity. To test this interpretation more directly, we compared profoundly and prelingually deaf, orally educated participants and hearing participants’ accuracy during a visual rhyming judgement task in which the two words of a pair share the orthographic rime, in order to discourage usage of a purely orthographic strategy. Accuracy was lower in deaf than in hearing participants. The gradient of difficulty between items, together with the finding of a significant correlation between accuracy and the consistency of the grapheme to rhyme, suggest that difference in accuracy between groups might be explained by an over regularization in deaf people, which is probably linked to less diversified phonological representations. 相似文献

Despite the fact that there are more than twenty thousand biomedical journals in the world, research into the work of editors and publication process in biomedical and health care journals is rare. In December 2012, the Esteve Foundation, a non-profit scientific institution that fosters progress in pharmacotherapy by means of scientific communication and discussion organized a discussion group of 7 editors and/or experts in peer review biomedical publishing. They presented findings of past editorial research, discussed the lack of competitive funding schemes and specialized journals for dissemination of editorial research, and reported on the great diversity of misconduct and conflict of interest policies, as well as adherence to reporting guidelines. Furthermore, they reported on the reluctance of editors to investigate allegations of misconduct or increase the level of data sharing in health research. In the end, they concluded that if editors are to remain gatekeepers of scientific knowledge they should reaffirm their focus on the integrity of the scientific record and completeness of the data they publish. Additionally, more research should be undertaken to understand why many journals are not adhering to editorial standards, and what obstacles editors face when engaging in editorial research. 相似文献

This review synthesises research on digital games and science learning as it supports the goals for science proficiency outlined in the report by the US National Research Council on science education reform. The review is organised in terms of these research-based goals for science proficiency in light of their alignment with current science education standards and reform documents worldwide. Overall, the review suggests that digital games can support science learning across the four strands but also suggests that there are few strong quantitative studies examining some of the strands. Much of the research conducted to date has centred primarily on the potential of games to scaffold conceptual knowledge, engagement and participation. Less research has focused on epistemological understanding and science process skills. While much debate has asked whether digital games are ‘good’ or ‘bad’ for learning, the research across the strands highlights that the design of digital games, rather than their medium, ultimately determines their efficacy for learning. 相似文献

This study reports on the steering of a self-access learning center in a Japanese university by its “middle management” committee over the first years of its operation. Middle management practice was informed by an ethnographic archive of various facets of center use, particularly concerning language policy and curriculum integration, issues about which the archive reveals considerable shifts in stakeholder views over time. It is argued that this evidence-based middle management style has been an effective, but sometimes limited, means in decision-making as it succeeds in placing research at the center of middle management activity, not at its periphery. 相似文献

The aim of this study was to identify anthropometric and biomotor variables that discriminated among groups of elite adolescent female athletes aged 14.3 ± 1.3 years (mean ± s) from four different sports (tennis, n = 15; swimming, n = 23; figure skating, n = 46; volleyball, n = 16). The anthropometric variables included body mass, height, bi-epicondylar breadth of the distal extremity of the humerus and femur, maximal girth of the calf and biceps and the sum of five adipose skinfolds. The biomotor variables were maximal aerobic power, muscular endurance and flexibility of the trunk. Discriminant analysis revealed three significant functions (P ? 0.05). The first discriminant function primarily represented differences between figure skaters and all other groups of athletes. The other two underlined anthropometric and biomotor differences between swimmers and volleyball players and between tennis players and swimmers, respectively. After validation, the analysis showed that 88% of the athletes were correctly classified in their respective sports. Our model confirms that elite adolescent female athletes show physical and biomotor differences that clearly distinguish them according to their particular sport. 相似文献

AbstractThe aim of this study was to investigate the effects of a single bout of whole-body vibration (WBV) on running gait. The running kinematic of sixteen male marathon runners was assessed on a treadmill at iso-efficiency speed after 10 min of WBV and SHAM (i.e. no WBV) conditions. A high-speed camera (210 Hz) was used for the video analysis and heart rate (HR) was also monitored. The following parameters were investigated: step length (SL), flight time (FT), step frequency (SF), contact time (CT), HR and the internal work (WINT). Full-within one-way analysis of variance (ANOVA) of the randomised crossover design indicated that when compared to SHAM conditions, WBV decreased the SL and the FT by ~4% (P < 0.0001) and ~7.2% (P < 0.001), respectively, and increased the SF ~4% (P < 0.0001) while the CT was not changed. This effect occurred during the first minute of running: the SL decreased ~3.5% (P < 0.001) and SF increased ~3.3% (P < 0.001). During the second minute the SL decreased ~1.2% (P = 0.017) and the SF increased ~1.1% (P = 0.02). From the third minute onwards, there was a return to the pre-vibration condition. The WINT was increased by ~4% (P < 0.0001) during the WBV condition. Ten minutes of WBV produced a significant alteration of the running kinematics during the first minutes post exposure. These results provide insights on the effects of WBV on the central components controlling muscle function. 相似文献
