The Fourth Edition of the Stanford-Binet and the WISC-R were compared as instruments for assessing the intellectual strengths and weaknesses of students classified as learning disabled in the primary and secondary grades. Results found only a 3.28-point difference (p≥.0001) between the S-B Composite score and the WISC-R Full Scale score. Correlations between the four broad areas of the S-B and the three scales of the WISC-R ranged from .494 (S-B Abstract/Visual Reasoning with WISC-R Verbal) to .920 (S-B Composite with WISC-R Full Scale). All correlations were found to be significant. Implications of the research findings were discussed.  相似文献

This article explores the textual and historical poaching practices by Tumblr fans of the novels A Song of Ice and Fire and the television adaption Game of Thrones, a pseudo-historical fantasy series. Fans critique both the text (novels and TV show) and other fans’ interpretations of the text, as well as parallel real-world history with the world and characters of the series. Tensions arise around the “historical accuracy” of the novels and show, along with the role that dominant narratives and cultural norms play in interpreting a past that never was through the lens of a real-world past. Fantasy and history intersect in layered ways and are used by fans to support a variety of textual points of view. Issues of violence, presentism, colonialism, gender, and “historical truths” are argued in relation to the ahistoricism or historicism of the novels/show.  相似文献

This study targeted to examine the effect of the ToyBox-intervention, a kindergarten-based, family-involved intervention, aiming to improve preschooler’s energy-related behaviours (e.g., physical activity) on motor performance ability. Physical activity sessions, classroom activities, environmental changes and tools for parents were the components of the 1-year intervention. The intervention and control were cluster-randomised, and children’s anthropometry and two motor test items (jumping from side to side, JSS and standing long jump, SLJ) were assessed. A total of 1293 (4.6 ± 0.69 years; 52% boys) from 45 kindergartens in Germany were included (intervention, n = 863; control, n = 430). The effect was assessed using generalised estimating equation. The intervention group showed a better improvement in JSS (Estimate 2.19 jumps, P = 0.01) and tended to improve better in SLJ (Estimate 2.73 cm, P = 0.08). The intervention was more effective in boys with respect to SLJ (P of interaction effect = 0.01). Children aged <4.5 years did not show a significant benefit while older children improved (JSS, Estimate 3.38 jumps, P = 0.004; SLJ, Estimate 4.18 cm, P = 0.04). Children with low socio-economic status improved in JSS (Estimate 5.98 jumps, P = 0.0001). The ToyBox-intervention offers an effective strategy to improve specific components of motor performance ability in early childhood. Future programmes should consider additional strategies specifically targeting girls and younger aged children.

Tracing one's family genealogy is a complex process that requires situating a family's narratives within a historical context. This article reviews the use of critical family history research in an undergraduate Asian American studies course to examine not only the diversity and experiences of Asian Americans but also the unspoken narratives that lead to the creation of a single story. We are told single stories that often neglect the sociocultural factors—the historical reality—of our past. Our family histories are constructed historically and are embedded in social, political, and economic processes and relationships. This article argues that we need to complicate what we know about our past and examine policies and cultural practices that lead to a racialized system of power and privilege, racialized policies, and racialized oppression and progression.  相似文献

Winter sports are played in cold conditions on ice or snow and often at moderate to high altitude. The most important nutritional challenges for winter sport athletes exposed to environmental extremes include increased energy expenditure, accelerated muscle and liver glycogen utilization, exacerbated fluid loss, and increased iron turnover. Winter sports, however, vary greatly regarding their nutritional requirements due to variable physiological and physique characteristics, energy and substrate demands, and environmental training and competition conditions. What most winter sport athletes have in common is a relatively lean physique and high-intensity training periods, thus they require greater energy and nutrient intakes, along with adequate food and fluid before, during, and after training. Event fuelling is most challenging for cross-country skiers competing in long events, ski jumpers aiming to reduce their body weight, and those winter sport athletes incurring repeated qualification rounds and heats. These athletes need to ensure carbohydrate availability throughout competition. Finally, winter sport athletes may benefit from dietary and sport supplements; however, attention should be paid to safety and efficacy if supplementation is considered.  相似文献
