Presently, science is an important precondition for the economic development of less-developed countries. This paper discusses the specific roles that science has at initial stages of development, pointing to its contributions for the countries’ absorptive capability. Furthermore, this paper specifies the role of science for initiating a positive interaction with technological development, since initial stages of development and during catching up processes. For less-developed countries, neither the linear model of technology nor an “inverted linear model” would take place: a more interactive approach is necessary for development. Using statistics of patents (USPTO) and scientific papers (ISI) for 120 countries (1974, 1982, 1990, and 1998), this paper analyses some evidences on thresholds levels of scientific production to originate an interactive relationship between science and technology. These data also document that the value of this threshold seems to double from one period to another. Although this paper presents tentative results, some policy implications are discussed: scientific institutional building must be seen as a component of modern industrial policies. 相似文献
Differences of gender and ethnicity were examined in terms of the perception of barriers to career development. The Perception of Career Barriers Inventory (IPBC) was administered to a sample of 457 ninth grade students in Portuguese state schools. Gender differences were found, with girls generally scoring higher and in particular on some specific scales. African ethnic participants score higher than Portuguese participants across all the IPBC scales. These findings are more obvious with African participants born in Africa than with those born in Portugal. Implications for future research and practice are discussed. 相似文献
This paper reports results from two studies aimed at examining whether perception of social acceptance and actual social acceptance
differ according to the presence of an illusion of scholastic incompetence. Results of both studies conducted in Belgium and
in Quebec (respectively 179 and 543 participants) show that children’s illusion of scholastic incompetence is linked to a
negative perception of social acceptance. However, according to the evaluation by peers, social acceptance of those children
is similar to the others. This suggests a generalization of the negative bias of self-evaluation to both academic and social
domains. The discussion proposes further variables that could improve the understanding of the origin of the illusion of incompetence. 相似文献
Three hundred and ninety-one children (195 girls; Mage = 9.56 years) attending Grades 1 and 5 completed implicit and explicit measures of math attitudes and math self-concepts. Math grades were obtained. Multilevel analyses showed that first-grade girls held a strong negative implicit attitude about math, despite no gender differences in math grades or self-reported (explicit) positivity about math. The explicit measures significantly predicted math grades, and implicit attitudes accounted for additional variance in boys. The contrast between the implicit (negativity for girls) and explicit (positivity for girls and boys) effects suggest implicit–explicit dissociations in children, which have also been observed in adults. Early-emerging implicit attitudes may be a foundation for the later development of explicit attitudes and beliefs about math. 相似文献
The results of three meta-analyses show that the effectiveness of learning from animations, when compared to learning from static pictures, is rather limited. A recent re-analysis of one of these meta-analyses, however, supports that learning from animations is considerably more effective than learning from static pictures if the specifics of the displayed changes need to be learned. In order to further validate this finding as well as to clarify the educational strengths and weaknesses of animations and static pictures, an experimental study with three groups was conducted. Overall, 88 university students participated in the study. One group of learners (n?=?30) watched a single picture of a gear mechanism, one group of learners (n?=?28) watched four pictures, and one group of learners (n?=?30) watched an animation. All groups had to identify specific motions and spatial arrangements covered by the gear mechanism. While learners who watched the animation exhibited the best performance with respect to the identification of motions, learners who watched the pictures showed the best performance with respect to the identification of spatial arrangements. The effect sizes are large. The results of the study help to clarify when animations and when static pictures are most suitable for learning.

This study investigated relationships between career adaptability and personality and pathological traits using the network analysis approach. We administered CAAS, BFI-2-S, and IDCP-2 to 630 working adults. We observed positive associations between personality and career adaptability and negative associations between pathological traits and career adaptability. This paper contributes to the understanding of the associations between career adaptability and Big Five personality traits and pathological traits. We found stronger associations between career adaptability and personality traits as compared to pathological traits. Our findings suggest that Neuroticism and Conscientiousness contribute more to adaptation to professional development tasks than do pathological traits.
