The acquisition of reading skill was studied in 503 Italian children in first to eighth grade using a task that required reading
of lists of words and non-words. Analysis of the metric characteristics of the measures indicated that reading speed but not
accuracy was normally distributed across all ages considered. The role of specific effects (length, word frequency, and lexicality)
versus global factors in reading speed was examined using the Rate–Amount Model (RAM). A global processing factor accounted
for a large portion of the variance. Specific influences of length, frequency, and lexicality were detected in different periods
of development over and above the global processing factor. Length modulated performance at early stages of learning and progressively
less later on; in the case of non-words, the effect of length was large but did not change as a function of grade. The lexicality effect, present at all ages for high frequency words and by third grade for low frequency words increased with reading practice
indicating a progressive differentiation in the ability to read words and non-words. Finally, the effect of word frequency
was highest in third grade and then decreased. These findings are discussed in terms of their relevance for reading acquisition
in a language with transparent orthography and their implications for evaluating developmental reading deficits. Overall,
it is proposed that RAM is a useful tool for disentangling the role of specific versus global factors in reading development. 相似文献

This paper aims to figure out the potential impact of Big Data (BD) on Critical Success Factors (CSFs) of Customer Relationship Management (CRM). In fact, while some authors have posited a relationship between BD and CRM, literature lacks works that go into the heart of the matter.Through an extensive up-to-date in-depth literature review about CRM, twenty (20) CSFs were singled out from 104 selected papers, and organized within an ad-hoc classification framework. The consistency of the classification was checked by means of a content analysis. Evidences were discussed and linked to the BD literature, and five propositions about how BD could affect CRM CSFs were formalized.Our results suggest that BD-enabled CRM initiatives could require several changes in the pertinent CSFs. In order to get rid of the hype effect surrounding BD, we suggest to adopt an explorative approach towards them by defining a mandatory business direction through sound business cases and pilot tests. From a general standpoint, BD could be framed as an enabling factor of well-known projects, like CRM initiatives, in order to reap the benefits from the new technologies by addressing the efforts through already acknowledged management paths. 相似文献

Abstract A project for the harmonization of Agricultural Engineering University Curricula was started in 1989 at European level. This project led to two seminars (in 1991 and 1992) and to a survey of current University organization and Curricula of Agricultural Engineering in 25 Countries. The harmonization project is still under way and has achieved world-wide interest. In this paper the main results already obtained, together with possible future developments, are presented. 相似文献

The activity of the research group for chemistry and integrated science education, operating in the University of Pisa, is presented. Two main areas are identified: analysis of the pupils’ preconceived ideas and consequent elaboration of teaching strategies. The interest is addressed towards the level of Italian elementary compulsory school, (pupils aged 6‐11 years). The work performed has noticeable effects in a proposal for a teaching model for in‐service training of teachers, addressed towards the present Italian situation. 相似文献

Stress assignment to Italian polysyllabic words is unpredictable, because stress is neither marked nor predicted by rule.
Stress assignment, especially to low frequency words, has been reported to be a function of stress dominance and stress neighbourhood.
Two experiments investigate stress assignment in sixth-grade, skilled and dyslexic, readers. In Experiment 1, skilled readers
were not affected by stress dominance. Dyslexic children, although affected by word frequency, made more stress regularisation
errors on low frequency words. In Experiment 2, stress neighbourhood affected low frequency word reading irrespective of stress
dominance for both skilled and dyslexic readers. Words with many stress friends were read more accurately than words with
many stress enemies. It is concluded that, in assigning stress, typically developing and developmental dyslexic Italian readers
are sensitive to the distributional properties of the language. 相似文献

Italian developmental dyslexic readers show a striking length effect and have been hypothesised to rely mostly on nonlexical reading. Our experiments tested this hypothesis by assessing whether or not the deficit underlying dyslexia is specific to lexical reading. The effects of lexicality, word frequency and length were investigated in the same group of children in four separate experiments. Although dyslexics were slower and less accurate than skilled readers and had large length effects, they showed lexicality and word frequency effects in both reading aloud and lexical decision. In a cross‐experiment comparison, we show that a single global factor explains a large proportion of the difference in reading performance between dyslexic and skilled readers. This factor may indicate a deficit at a prelexical level of analysis. Lexical activation seemed spared in the dyslexic children based on the effects of lexicality and frequency. These findings contrast the hypothesis that Italian dyslexics primarily engage in nonlexical reading. 相似文献

This study examines the effects of orthographic neighborhood size (N-size) in relationship with word frequency on the reading aloud of children with and without dyslexia whose language has a consistent orthography. Participants included 22 Italian fourth-grade children with dyslexia and 44 age-matched typically developing readers. Children with dyslexia read low-frequency words with high N-size faster than words that had no neighbors; by contrast, typically developing readers showed no N-size effects, irrespective of word frequency. The facilitating effect of N-size on low-frequency word reading in children with dyslexia indicates that they benefit from lexical activation spreading from dense neighborhoods. 相似文献

In pronounced contrast to English, Italian orthography contains extremely regular sound-to-spelling correspondences and therefore Italian words could, in principle, be spelled perfectly correctly using nonlexical phoneme-to-grapheme conversion rules alone. If this were so, then there should be no lexical influence upon nonword spelling. However, the present experiment reports lexical priming effects for two inconsistently spelled segments in Italian words: Italian participants were more likely to spell the nonword tece as TECIE if they had just heard the word specie rather than pece and were more likely to spell the nonword cuodo as QUODO if they had heard the word quota rather than cuoco. These results suggest that Italian, despite its regular orthography, is not spelled purely nonlexically. It is argued that a dual-route model of spelling production can be applied to Italian. 相似文献
