Dyslexic difficulties in lexical stress were compared to difficulties in segmental phonology. Twenty-nine adolescents with dyslexia and 29 typically developing adolescents, matched on age and nonverbal ability, were assessed on reading, spelling, phonological and stress awareness, rapid naming, and short-term memory. Group differences in stress assignment were larger than in segmental phonology in reading and spelling pseudowords but not words, indicating a fragility of explicit processes that manipulate stress representations. Despite impaired stress performance in dyslexia at the group level, individual variability failed to reveal evidence for a stress-specific deficit or for a distinct stress-impaired subgroup. 相似文献

This work explores the relationship between product innovation and the decision to invest in fixed capital assets among a sample of SMEs in six European Union countries located in both peripheral and more central areas. We find that the presence of product innovation reduces the probability to invest. A firm’s size exerts a direct, inverted U-shape effect on the probability to invest and an indirect effect through the linear effect of size on the probability to innovate. The gap in the probability to invest between innovative and non-innovative firms increases with size. 相似文献

This study focuses on the process by which children develop a formal mathematical concept of the circle by using various instruments
to draw circles within the context of a goal-directed drawing task. Particular attention was given to the transition from
using tracers and templates to using a compass for drawing circles and to the extent to which the use of different drawing
instruments may contribute to the formation of a formally defined mathematical concept of the circle. The critical difference
considered in the study is that the compass, in contrast to circle-drawing tracers or templates, induces by its physical structure
and its functional use the generative features of formal mathematical concepts of the circle, that is, the centre and the
radius. Analysis of the empirical data indicates that the use of the compass in circle drawing structures the circle-drawing
operation in a radically different fashion than circle tracers and templates, and brings into play an action-bound practical
thinking. Such thinking has an overall positive influence on the construction of analytical concepts by children that are
analogous to the formally defined mathematical concepts of the circle.

ABSTRACT News organizations increasingly focus their efforts to boost traffic on their websites to grow their share of online advertising. We investigated the relationship between news websites’ traffic ranking and their social media tools of Facebook, Twitter, YouTube and Google Plus. For a year we monitored the followers of all Greek regional newspapers in relation to the traffic on their websites. We continued monitoring for a second year to validate the robustness of the findings and we hereby present results for 86 weeks. Statistical analysis leads to the conclusion that the number of social media subscribers can predict the competitive position of a newspaper in the market based on its website traffic. The effect lasts for a limited period of time, one to three weeks, depending on the specific medium. Importantly, results indicate the potential of developing a prediction model of the website’s traffic, based on the social media metrics of the organization, as a useful tool to increase traffic and revenues from online advertising. 相似文献

This article examines the role of market-based policies in special education, focusing on the case of voucher programs. It examines the nature of contemporary social reforms, while discussing school choice as the theoretical linchpin of a market model for educational reforms. Moreover, it includes analysis of why the market-driven rationale of vouchers erodes the public functions of special education. Despite their current implementation on a small scale, vouchers have the potential to become a threat to free and appropriate public special education. 相似文献

Developing and maintaining e-Government services that can effectively deal with changes is a challenge for public administrations. In this paper, we address this challenge by presenting an ontology-based approach that: (i) enables systematic response of e-Government systems to changes by applying formal methods for achieving consistency when a change is discovered; (ii) enables knowledgeable response of service designers and implementers to changes by utilizing design rationale knowledge. We argue that such a synthesis of systematic response to changes with knowledge to deal with them has a positive impact on the change management process. Evaluation of the proposed approach in three case studies let us develop useful propositions for practitioners, discuss policy implications and identify future research topics. 相似文献

Although a growing number of research articles in recent years have treated the role of informal settings in science learning, the subject of the history of science in museums and its relationship to informal and non-formal education remains less well explored. The aim of this review is to assemble the studies of history of science in science museums and explore the opportunities for the further use of the history of science in science museum education practice. 相似文献

The self‐esteem as physics teachers of students taking pre‐service physics teacher education courses was investigated before and after the courses. It was found that students who dropped out from the courses had lower self‐esteem than either the students who satisfactorily completed them or similarly qualified students who did not take the courses. There was some evidence that learning pedagogical theory enhances self‐esteem if it takes place after practical teaching experience but has the opposite effect when taught first, in the absence of any practical teaching experience. 相似文献
