Investigating the causes of reading comprehension failure: The comprehension-age match design 总被引:1,自引:0,他引:1
The reading-level (or reading-age) match design has become a widely-used tool for investigating the possible direction of the relation between particular skills and word reading ability: Cause or consequence. This paper outlines an analogous method for identifying candidate causes of reading comprehension failure, the `comprehension-age match design' and discusses the strengths and limitations of this design. 相似文献

Inference making ability and its relation to comprehension failure in young children 总被引:1,自引:0,他引:1
Young children's reading comprehension skill is associated with their ability to draw inferences (Oakhill 1982, 1984). An experiment was conducted to investigate the direction of this relation and to explore possible sources of inferential failure. Three groups of children participated: Same-age skilled and less skilled comprehenders, and a comprehension-age match group. The pattern of performance indicated that the ability to make inferences was not a by-product of good reading comprehension, rather that good inference skills are a plausible cause of good reading comprehension ability. Failure to make inferences could not be attributed to lack of relevant general knowledge. Instead, the pattern of errors indicated that differences in reading strategy were the most likely source of these group differences. 相似文献

This paper explores the role of The Library Association in providing and supporting opportunities for continuing professional development. Formal requirements for gaining qualifications are explained. The services and products of the Association designed specifically to meet the needs of those seeking formal professional development are outlined. Emphasis is placed on the opportunities offered to gain practical skills through active participation in professional activities. A brief conclusion points to the increasing emphasis on the need for continuing professional development at national level and within the profession. 相似文献

AbstractBIBCO is one of four programs in the PCC. This article summarizes the development of BIBCO and how its cataloging training program was strikingly different from the other three programs: NACO, CONSER and SACO. BIBCO grew out of the 1990–1991 recession which created widespread anxiety over the cost of original cataloging. BIBCO attempted to reduce the cost without sacrificing quality and increase record production through the use of core records. The early training emphasized the value of cooperation. PCC’s strength in this area is seen today in its partnerships and leadership in metadata initiatives such as linked data. 相似文献

This study used accelerometer and self-report measures of overall sedentary time (ST) and screen time behaviours to examine their respective associations with adiposity among UK youth. Participants (Year groups 5, 8, and 10; n=292, 148 girls) wore the SenseWear Armband Mini accelerometer for eight days and completed the Youth Activity Profile, an online report tool designed to estimate physical activity and ST.Stature, body mass and waist circumference were measured to classify adiposity outcomes (overweight/obese and central obesity). One-way between groups ANOVA and adjusted linear, logistic and multinomial logistic regression analyses were conducted. There was a significant main effect of age on total ST across the whole week (F(2, 289)=41.64, p≤0.001). ST increased monotonically across Year 5 (581.09±107.81 min·dˉ¹), 8 (671.96±112.59 min·dˉ¹) and 10 (725.80±115.20 min·dˉ¹), and all pairwise comparisons were significant at p≤0.001. A steep age-related gradient to mobile phone use was present (p≤0.001). ST was positively associated with adiposity outcomes independent of moderate-to-vigorous intensity physical activity (MVPA; p≤0.001). Engaging in >3 hours of video gaming daily was positively associated with central obesity (OR=2.12, p≤0.05) but not after adjustment for MVPA. Results further demonstrate the importance of reducing overall ST to maintain healthy weight status among UK youth. 相似文献

Discoloured 18-carat gold decorations from Sweden have been analysed by scanning electron microscopy with energy dispersive X-ray spectroscopy and X-ray electron spectroscopy (XPS)/electron spectroscopy for chemical analysis (electron spectroscopy).The original gold composition was close to 75% gold, 13% silver, and 12% copper. After manufacture, many details were boiled in sulphuric acid. As a consequence of this, the surfaces are irregular and porous with a gold concentration around 90% and with less than 1% copper. With XPS the outermost 10–20 atomic layers could be examined. No copper was present here, and the silver concentration was significantly higher. Also carbon, sulphur, oxygen, and (in one case) chlorine were present. The valence numbers indicated that gold only occurred in its metallic state, while silver (as Ag+) was preferably associated with sulphur to form black silver sulphide (Ag2S). The grey discolorations are basically due to silver sulphide and organic dirt. Sometimes green, violet, and ‘copper-shining’ colours occur, presumably as a result of light refraction phenomena. 相似文献

ABSTRACTHampton Court Palace’s Great Hall located in Surrey, UK, is a magnificent late medieval hall. Its large hammer-beam roof is sumptuously decorated while its walls for the past century have been rehung with Henry VIII’s five-hundred-year-old tapestries illustrating The Story of Abraham, and one of the most internationally significant sets of sixteenth-century tapestries, commissioned for the same hall. This paper presents research which began in 2007, exploring conservation solutions based on evidence-based decision-making, through to successful implementation of measures that conserve these invaluable tapestries without damaging the aesthetic or physical integrity of the Great Hall. The impacts of environmental exposure conditions mapped in detail were assessed to evaluate risk for each tapestry. Next, feasibility studies identified the effectiveness of a range of potential mitigating options to address each local risk, now being incrementally implemented over many years. The research has enabled us to develop, test and deliver permanent interventions that have – when considered together as a holistic management regime – allowed the tapestries to remain in situ. These interventions will continue to be monitored and evaluated for at least a further year to confirm their effectiveness. 相似文献
