Low reading comprehension persists among deaf readers, and recent research indicates that low automaticity in recognizing words and parsing sentence patterns is a significant source of the difficulty. When a learner does manage to gain an insight about some aspect of printed English, there may be limited impact on comprehension until the new knowledge can be applied fluently because the multiple cognitive demands of reading call for completing basic linguistic operations with a minimum of conscious effort. The research literature agrees that the route to improved automaticity is effective practice, and, thus, practice is also a likely route to increased comprehension. This article presents considerations to guide the design of practice for deaf readers. Certain of these notions are relatively applied in nature and may shape practice activities directly, for example, the discussion of research-based guidelines for tailoring the sequence and composition of practice items. Other parts of the discussion, such as those related to word recognition, are more theoretical than directive, and they imply research hypotheses that can and should be tested empirically. A principal point of this article is that without appreciable improvements in practice, the reading of many deaf students will remain largely unimproved. 相似文献

Few women breastfeed for 6 months or longer, and many who stop breastfeeding do so in the early postpartum period. To increase the number of breastfeeding mothers, health-care providers need to identify women at greatest risk for early breastfeeding attrition. This integrative review describes instruments used to assess breastfeeding in the early postpartum period and reports the results of studies using these tools. The instruments are then evaluated for similarities in variables and usefulness for clinical practice. 相似文献

The relative length of the second and fourth digits (2D:4D) is a putative marker for prenatal testosterone. Low 2D:4D has been reported to correlate with high performance in sport in general. Here, for the first time, we examine the relationship between 2D:4D and performance in elite rugby players. The 44 players (28 forwards, 16 backs) were drawn from the Ospreys Rugby Union Club and 44 age-matched controls. The measures of performance comprised age-adjusted number of international performances (caps) for Wales, a comparison of coaches' first-choice League team with others, and the number of tries scored by backs in club matches. Compared with controls, players were larger and had lower 2D:4D for the right and left hand. With regard to number of caps, players with low 2D:4D in their right hand and low right 2D:4D compared with their left (right?-?left 2D:4D difference) had high numbers of caps. First-choice players did not differ significantly from second-choice players in their 2D:4D but they did have a lower right?-?left 2D:4D difference than second-choice players. Low right 2D:4D and low right?-?left 2D:4D difference were significantly linked with large numbers of tries. We conclude that low right 2D:4D and low right?-?left 2D:4D difference are predictors of high rugby performance. 相似文献

The ascidian Ciona intestinalis is a model organism of developmental and evolutionary biology and may provide orucial clues concerning two fundamental matters, namely, how chordates originated from the putative deuterostome ancestor and how advanced chordates originated from the simplest chordates. In this paper, a whole-life-span culture of C. intestinalis was conducted. Fed with the diet combination of dry Spirulina, egg yolk, Dicrateria sp., edible yeast and weaning diet for shrimp, C. intestinalis grew up to average 59 mm and matured after 60 d cultivation. This culture process could be repeated using the artificially cultured mature ascidians as material. When the fertilized eggs were maintained under 10, 15, 20, 25 ℃, they hatched within 30 h, 22 h, 16 h and 12 h 50 min respectively experiencing cleavage, blastulation, gastrulation, neurulation, tailbud stage and tadpole stage, The tadpole larvae were characterized as typical but simplified chordates because of their dorsal nerve cord, notochord and primordial brain. After 8-24 h freely swimming, the tadpole larvae settled on the substrates and metamorphosized within 1-2 d into filter feeding sessile juvenile ascidians. In addition, unfertilized eggs were successfully dechorionated in filtered seawater containing 1% Tripsin, 0.25% EDTA at pH of 10.5 within 40 min. After fertilization, the dechorionated eggs developed well and hatched at normal hatching rate. In conclusion, this paper presented feasible methodology for rearing the tadpole larvae of C. intestinalis into sexual maturity under controlled conditions and detailed observations on the embryogenesis of the laboratory cultured ascidians, which will facilitate developmental and genetic research using this model system. 相似文献

从美国的观点看继续教育 总被引：2，自引：0，他引：2
当今市场更具有全球性，经济在迅猛发展，许多国家中具有进取心和生产能力的公司均在高度竞争。而技术的进步能为企业开拓国内外市场提供竞争能力。工业采用技术的成功以及生产的发展决定其人员的素质，素质依赖于人们所受的教育。教育虽不是影响经济增长的唯一因素，但却是主要因素。激烈的世界性竞争，技术的迅速发展使一个工程师的技能往往在毕业后３～７年便落后。贯穿于职业过程中的教育能帮助工程师提高其胜任工作的能力。这种教育不仅有助于工程师个入更有效地工作，也有利干公司形成技术人员队伍，从而可以承担新的生产任务。继续教… 相似文献
