Data from 918 children from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care were examined to test the interrelation of attachment and attentional performance and 2 known risks for poor attentional performance: male gender and social-contextual adversity. Attachment was measured using the Strange Situation at 15 months, attentional performance by a Continuous Performance Test (CPT) and maternal questionnaires at 54 months, and social-contextual adversity by a variety of measures from birth to 54 months. Findings indicated (a) that children with secure attachment were less susceptible to the effects of cumulative risk and gender on CPT attentional performance than their insecure counterparts and that (b) no such differential risk susceptibility was evident for maternal reports of attention-related behavior problems. 相似文献

Tracking studies show that museum visitors typically view only 20 to 40 percent of an exhibition. Current literature states that this partial use sub‐optimizes the educational benefit gained by the visitor, and that skilled visitors view an exhibition comprehensively and systematically. Contrary to that viewpoint, this paper argues that partial use of exhibitions is an intelligent and effective strategy for the visitor whose goal is to have curiosity piqued and satisfied. By using analytical approaches derived from “optimal foraging theory” in ecology, this paper demonstrates that the curiosity‐driven visitor seeks to maximize the Total Interest Value of his or her museum visit. Such visitors use a set of simple heuristics to find and focus attention only on exhibit elements with high interest value and low search costs. Their selective use of exhibit elements results in greater achievement of their own goals than would be gained by using the exhibition comprehensively. 相似文献

ABSTRACT How do educators capitalize on students’ comfort with ubiquitous communications in order to develop information literacy skills required in the 21st century? A curriculum materials librarian and a professor in the School of Education present an approach that uses library instruction, online research scaffolds, and peer evaluation within a class wiki to enhance student research practices and academic achievement. The explosion of information sources and access to networked technologies has provided the opportunity to “ratchet up” the expectations for student research in higher education. The Association of College & Research Libraries's information literacy standards for higher education provide a framework for setting these expectations. The authors describe features of an introductory education course that seeks to enhance honors freshman students’ knowledge of library research resources, efficient research skills, and scholarly writing, as described in these standards. 相似文献

Heavy training is associated with increased respiratory infection risk and antimicrobial proteins are important in defence against oral and respiratory tract infections. We examined the effect of 14 weeks of vitamin D3 supplementation (5000 IU/day) on the resting plasma cathelicidin concentration and the salivary secretion rates of secretory immunoglobulin A (SIgA), cathelicidin, lactoferrin and lysozyme in athletes during a winter training period. Blood and saliva were obtained at the start of the study from 39 healthy men who were randomly allocated to vitamin D3 supplement or placebo. Blood samples were also collected at the end of the study; saliva samples were collected after 7 and 14 weeks. Plasma total 25(OH)D concentration increased by 130% in the vitamin D3 group and decreased by 43% in the placebo group (both P = 0.001). The percentage change of plasma cathelicidin concentration in the vitamin D3 group was higher than in the placebo group (P = 0.025). Only in the vitamin D3 group, the saliva SIgA and cathelicidin secretion rates increased over time (both P = 0.03). A daily 5000 IU vitamin D3 supplement has a beneficial effect in up-regulating the expression of SIgA and cathelicidin in athletes during a winter training period, which could improve resistance to respiratory infections. 相似文献

Composing hypertext documents can be an enriching path into the world of technical communication. In learning to produce hypertext, students are introduced to an important form of written composition that encompasses not only text generation, but also visual communication and information architecture. In this article, I provide a rationale for teaching hypertext composition and then some specific curricular suggestions in two parts, one for teaching beginners, and one for teaching more advanced students. 相似文献

Influence of mother, father, and child risk on parenting and children's cognitive and social behaviors 总被引:1,自引:0,他引:1
The association among mothers', fathers', and infants' risk and cognitive and social behaviors at 24 months was examined using structual equation modeling and data on 4,200 on toddlers and their parents from the Early Childhood Longitudinal Study, Birth Cohort. There were 3 main findings. First, for cognitive outcomes, maternal risk was directly and indirectly linked to it through maternal sensitivity whereas paternal risk was only indirectly related through maternal sensitivity. Second, for social behaviors, maternal and paternal risks were indirectly linked through maternal sensitivity and father engagement. Third, maternal and paternal levels of risk were linked to maternal supportiveness whereas mothers' and children's risk were linked to paternal cognitive stimulation. Implications are that policy makers must take into account effects of mothers', children's, and fathers' risk on young children's functioning. 相似文献

The purpose of this study was to investigate variables related to the professional identity and career path of school-based vs. non-school-based doctoral-level school psychologists. Two hundred seventy-three psychologists trained as school psychologists completed a questionnaire developed to investigate their training, experience, and perceptions. Respondents differed little by employment setting (school-based vs. non-school-based) in reports of their training or experiences. However, significant differences were found among groups in two areas: ratings of relative importance of characteristics of employment setting, and perceived identity as a school psychologist. 相似文献

The classical Greek discourse on techne has much to offer technical communication teachers concerned about the relationship between theory and practice, but this potential has not yet been realized. Plato's and Aristotle's discussions about the relationship between techne and rhetoric, for example, encompass questions about the rhetorical goals of the speakedwriter and about the role of theory in teaching rhetorical art that are of continuing relevance to the modern discourse on technical communication. The aim of this article is to identify several points upon which a fruitful dialogue between ancient and modern discourses can begin. First, I supply some background on how the term techne was used up through the fourth century BCE. Then I discuss how the modern discourse on technical communication (including material from popular textbooks) both converges with and departs from Plato's and Aristotle's statements on the relationship between techne and rhetoric. Finally, I point out areas for further discussion as teachers of technical communication continue to reflect upon and refine their pedagogies. 相似文献
