In this report, we propose a model of spelling acquisition inspired by statistical learning and a frame-like model of orthographic representations: the fuzzy representation model. To provide an initial test of the model’s predictions for inconsistent words, 107 French-speaking children in Grades 1 to 3 were asked to spell words ending with a silent letter. Half of the words ended with the frequent silent t and half with the less frequent silent d. As predicted, children accurately spelled more t- than d-words. Most errors were omissions and substitutions of the silent letter. Consistent with statistical learning, there was some evidence that children used the preceding orthographic context when making substitution errors. The proportion of omissions, however, was not consistent with the statistical properties of French. These findings are discussed in light of the fuzzy representation model, whereby inconsistencies in words are more likely to be underspecified, if represented at all. 相似文献

Medical diagnosis software and computer-assisted surgical systems often use segmented image data to help clinicians make decisions. The segmentation extracts the region of interest from the background, which makes the visualization clearer. However, no segmentation method can guarantee accurate results under all circumstances. As a result, the clinicians need a solution that enables them to check and validate the segmentation accuracy as well as displaying the segmented area without ambiguities.With the method presented in this paper, the real CT or MR image is displayed within the segmented region and the segmented boundaries can be expanded or contracted interactively. By this way, the clinicians are able to check and validate the segmentation visually and make more reliable decisions. After experiments with real data from a hospital, the presented method is proved to be suitable for efficiently detecting segmentation errors. The new algorithm uses new graphic processing uint (GPU) shading functions recently introduced in graphic cards and is fast enough to interact on the segmented area, which was not possible with previous methods. 相似文献

Excavations in Sint-Lievens-Houtem (Flanders, Belgium), an important medieval pilgrimage village, uncovered a fourteenth-century refuse pit. This feature contained a fragment of a rare Andalusī moulded lustreware vessel, dating to the mid or second half of the twelfth century. The reconstruction of the vessel’s itinerary aids in understanding how an object travelled from Muslim Spain to Catholic Flanders and why it ended up under Sint-Lievens-Houtem’s marketplace, about two centuries after its production. Traditional explanations of Crusades or trade seem unlikely or do not account for the entire trajectory of the vessel. These narratives are therefore extended with the incorporation of the vessel in Sint-Lievens-Houtem’s church treasury. This biographical approach offers a valuable framework to interpret the increasing number of Islamic finds across Europe, the way by which they travelled north and the contexts in which they functioned. 相似文献

AbstractFranciscus Van den Enden (1602–1674) is commonly considered as the man who taught Latin to B. de Spinoza (1632–1677). It is unknown if he actually taught him something else, but we do know he used a pedagogy of his own and made the young philosopher aware of the importance of pedagogical issues. The present article helps to document their relationship from a historical and theoretical perspective, by clarifying Van den Enden’s ideas on a most debated subject: the use of honorary titles to distinguish pupils in the classroom. In particular, it shows how the rejection by Van den Enden of titles commonly used in Jesuits schools finds echoes in Spinoza’s philosophy. At the same time, the article argues that through their common participation in theatrical plays, Van den Enden and Spinoza shared a pedagogical experience that helped to overcome the problems linked to the introduction of a hierarchy, not theoretically, but in practice. 相似文献

ABSTRACTWe investigated how and when French children in Grades 1–5 acquire orthographic representations for silent letters and double consonants. Linear mixed-effects modeling analyses on the spelling accuracy scores obtained for 2,519 French words were used to test our predictions. As predicted, the presence of a silent letter or double consonant had a unique detrimental effect on spelling accuracy that was not captured by the inconsistency and complexity generated by these letters, and this effect tended to decrease across grades. Important to note, exposure to more frequent silent-letter endings or double consonants had a facilitative effect over and above consistency that did not seem to change across grades. These findings suggest that children implicitly acquire representations for letters with no phonological value. The results obtained for other predictors also suggest a shift from a lower level, phoneme-based processing to a higher level processing at the word and rime levels as children acquire more reading experience. 相似文献

The objective of this study was to develop a measuring instrument for assessing sexual actualization of the elderly and test some of its metrological properties. The assistance of experts on sexology, gerontology, and the actualization of potential was required. The questionnaire was sent twice, at a 2-week interval, to individuals who showed an interest in the study. Of the 115 people who answered the questionnaire, 52 were women, with a mean age of 67.3, and 63 were men, with a mean age of 68.9. The results show good temporal stability (intraclass correlation coefficient =.89) and strong internal consistency (Cronbach's alpha =.97). Two construct validity studies were conducted. The first consisted in comparing the Sexual Actualization Questionnaire (SAQ) and a general well-being scale; no significant relationship was found (r =.07; p =.41). However, the results of the second study, which compared the SAQ scores of the senior individuals who had been sexually active with those who had not, were significant (p <.05). 相似文献

Nowadays, fixed gear competitions on outdoor circuits such as criteriums are regularly organized worldwide. To date, no study has investigated this alternative form of cycling. The purpose of the present study was to examine fixed gear performance indexes and to characterize physiological determinants of fixed gear cyclists. This study was carried out in two parts. Part 1 (n?=?36) examined correlations between performance indexes obtained during a real fixed gear criterium (time trial, fastest laps, averaged lap time during races, fatigue indexes) and during a sprint track time trial. Part 2 (n?=?9) examined correlations between the recorded performance indexes and some aerobic and anaerobic performance outputs (VO2max, maximal aerobic power, knee extensor and knee flexor maximal voluntary torque, vertical jump height and performance during a modified Wingate test). Results from Part 1 indicated significant correlations between fixed gear final performance (i.e. average lap time during the finals) and single lap time (time trial, fastest lap during races and sprint track time trial). In addition, results from Part 2 revealed significant correlations between fixed gear performance and aerobic indicators (VO2max and maximal aerobic power). However, no significant relationship was obtained between fixed gear cycling and anaerobic qualities such as strength. Similarly to traditional cycling disciplines, we concluded that fixed gear cycling is mainly limited by aerobic capacity, particularly criteriums final performance. However, specific skills including technical competency should be considered. 相似文献
