This study assessed the developmental profile of unisensory and multisensory processes, and their contribution to children's intellectual abilities (8- and 11-year olds, = 38, compared to adults, = 19) using a simple audiovisual detection task and three incidental associative learning tasks with different sensory signals: visual-verbal with pseudowords, novel audiovisual, and visual-visual. The level of immaturity throughout childhood was dependent on both, the sensory signal type and the task. Associative learning was significantly enhanced with verbal sounds, compared to novel audiovisual and unisensory visual learning. Visual-verbal learning was also the best predictor of children's general intellectual abilities. The results demonstrate a separate developmental trajectory for visual and verbal multisensory processes and independent contributions to the development of cognitive abilities throughout childhood.  相似文献

Microrheometry is very important for exploring rheological behaviours of several systems when conventional techniques fail. Microrheometrical measurements are usually carried out in microfluidic devices made of Poly(dimethylsiloxane) (PDMS). Although PDMS is a very cheap material, it is also very easy to deform. In particular, a liquid flowing in a PDMS device, in some circumstances, can effectively deform the microchannel, thus altering the flow conditions. The measure of the fluid relaxation time might be performed through viscoelasticity induced particle migration in microfluidics devices. If the channel walls are deformed by the flow, the resulting measured value of the relaxation time could be not reliable. In this work, we study the effect of channel deformation on particle migration in square-shaped microchannel. Experiments are carried out in several PolyEthylene Oxyde solutions flowing in two devices made of PDMS and Poly(methylmethacrylate) (PMMA). The relevance of wall rigidity on particle migration is investigated, and the corresponding importance of wall rigidity on the determination of the relaxation time of the suspending liquid is examined.  相似文献

Despite the critical role of regulations on competition and innovation, little is known about firm responses and related effects on performance under regulatory contingencies that are permissive or restrictive. By longitudinally investigating hybrid cars competing in the Le Mans Prototype racing (LMP1), we counter-intuitively suggest that permissive regulations increase technological uncertainty and thus decrease the firms’ likelihood of shifting their technological trajectory, while restrictive regulations lead to the opposite outcome. Further, we suggest that permissive regulations favour firms that innovate their products by sequentially upgrading core and peripheral subsystems, while restrictive regulations (in the long term) favour firms upgrading them simultaneously. Implications for theory and practice are discussed.  相似文献

Objective

The reliability of child witness testimony in sexual abuse cases is often controversial, and few tools are available. Criteria-Based Content Analysis (CBCA) is a widely used instrument for evaluating psychological credibility in cases of suspected child sexual abuse. Only few studies have evaluated CBCA scores in children suspected of being sexually abused. We designed this study to investigate the reliability of CBCA in discriminating allegations of child sexual abuse during court hearings, by comparing CBCA results with the court's final, unappealable sentence. We then investigated whether CBCA scores correlated with age, and whether some criteria were better than others in distinguishing cases of confirmed and unconfirmed abuse.

Methods

From a pool of 487 child sexual abuse cases, confirmed and unconfirmed cases were selected using various criteria including child IQ ≥ 70, agreement between the final trial outcome and the opinion of 3 experts, presence of at least 1 independent validating informative component in cases of confirmed abuse, and absence of suggestive questions during the child's testimonies. This screening yielded a study sample of 60 confirmed and 49 unconfirmed cases. The 14 item version of CBCA was applied to child witness testimony by 2 expert raters.

Results

Of the 14 criteria tested, 12 achieved satisfactory inter-rater agreement (Maxwell's Random Error). Analyses of covariance, with case group (confirmed vs. unconfirmed) and gender as independent variables and age as a covariate, showed no main effect of gender. Analyses of the interaction showed that the simple effects of abuse were significant in both sex. Nine CBCA criteria were satisfied more often among confirmed than unconfirmed cases; seven criteria increased with age.

Conclusion

CBCA scores distinguish between confirmed and unconfirmed cases. The criteria that distinguish best between the 2 groups are Quantity of Details, Interactions, and Subjective Experience. CBCA scores correlate positively with age, and independently from abuse; all the criteria test except 2 (Unusual Details and Misunderstood Details) increase with age. The agreement rate could be increased by merging criteria Unusual and Superfluous details that achieve a low inter-rater agreement when investigated separately.

Practice implication

Given its ability to distinguish between confirmed and unconfirmed cases of suspected child abuse, the CBCA could be a useful tool for expert opinion. Because our strict selection criteria make it difficult to generalize our results, further studies should investigate whether the CBCA is equally useful in the cases we excluded from our study (for example mental retardation).  相似文献

This paper analyses the market transformation in heritage tourism destinations when excessive tourism demand determines the emergence of a class of excursionists among visitors. Building on the approach of Keane (1997) and Shapiro (1983), some important dimensions of sustainable tourism development are highlighted. The lesser capacity of excursionists to learn the true quality of the tourist goods provides an opportunity for producers to cut back on quality. To serve high quality goods and keep up the reputation of the destination, producers need to gain a mark-up on price that might not be sustained in a competitive market. Hence the decline in ``high-paying' demand segments, increasingly substituted by visitors with lesser quality expectations, has significant consequences on the use and preservation of the heritage. The proposed formulation allows the identification of appropriate policy instruments to reverse this process.  相似文献

Handwriting is a complex activity that involves continuous interaction between lowerlevel perceptual-motor and higher-level cognitive processes. All handwriting models describe involvement of executive functions (EF) in handwriting development. Particular EF domains associated with handwriting include maintenance of information in working memory, inhibition of prepotent responses, and shifting and sustaining of attention. Generativity, an EF domain that has not been extensively studied, may play a role in the acquisition and automation of handwriting. We hypothesized that neuropsychological performances and handwriting fluency would be mutually associated, and that visuospatial generativity could have a specific role in handwriting speed. We enrolled 96 children who completed a comprehensive neuropsychological battery. The study found that handwriting speed was associated with visuospatial fluency, which involves behavioural execution and initiation. In learning and performing handwriting, there is an inherent non-exclusive role of fine motor skills.  相似文献

ABSTRACT

This article presents a critical policy historiography of how Early School Leaving has been understood as a social problem and what policy responses have been enacted to tackle it in the Italian context, devoting a specific attention to the analysis of the translation of EU policy ideas, tools and recipes to reduce ESL. It shows how the formulation of a global and integrated national strategy to tackle ESL in Italy in 2018 can be interpreted as the result of a troubled process of re-culturing. Such a reculturing is the effect of the complex interplay between the legacies of the Italian welfare regime in education and the co-option of the ESL issue within a EU political frame that struggles to combine economic rationalism and social justice. Such a struggle is interpreted as contributing to a profound rethinking of education and its mission.  相似文献
