In this work, we elaborate on the meaning of metadata quality by surveying efforts and experiences matured in the digital library domain. In particular, an overview of the frameworks developed to characterize such a multi-faceted concept is presented. Moreover, the most common quality-related problems affecting metadata both during the creation and the aggregation phase are discussed together with the approaches, technologies and tools developed to mitigate them. This survey on digital library developments is expected to contribute to the ongoing discussion on data and metadata quality occurring in the emerging yet more general framework of data infrastructures. 相似文献

In the current study the reading speed of the narration and the difficulty of the text was manipulated and links were explored with children’s attention to the printed text in shared book reading. Thirty-nine children (24 grade 1 and 15 grade 2) were presented easy and difficult books at slow (syllable by syllable) or fast (adult reading speed) pace while their eye movements were monitored. Results revealed an interaction between speed and difficulty. For the easy and difficult books, children spent more time and made more fixations on the printed text when it was presented at slow speed than at fast speed. However, at fast speed, children spend more time and made more fixations on the text of the easy rather than the difficult books, but at slow speed no difference was observed. In addition, at slow speed positive correlations were observed between attention to print and letter knowledge and word reading skills. Results provide important information for the practice of shared book reading suggesting that to increase attention to print, speed should be reduced. Future research should investigate the role of reading speed on reading related outcomes such as discourse comprehension and children’s interest in reading activities. 相似文献

Newborn infants who showed anthropometric signs of atypical patterns of fetal growth were compared with infants of appropriate growth on the Neonatal Behavioral Assessment Scale (NBAS) and on recently developed supplementary items. The sample consisted of lower-socioeconomic-status families in San Juan, Puerto Rico, and included teenage and older mothers. Infants with atypical patterns of fetal growth showed lower scores than did infants of appropriate growth on the NBAS orientation, motor, and reflex clusters and on 15 of the 18 supplementary scores. Gestational age was covaried and showed independent effects on 6 items. Differential effects on measures of state and autonomic function were also found when the effects of the ponderal index were held constant. The results suggested that neonatal behavior is related to multiple indices of fetal growth patterns that may indicate early versus late nutritional insult. Supplementary NBAS items do not improve the discriminability of the NBAS but may help explain the basis for observed group differences. 相似文献

In this article we consider the development of key policy issues in England, related to the area of literacy learning and children who are considered to have difficulties in literacy in their early years. We trace the tensions which have arisen since the 1980s between different policies and practices in these areas. These tensions include pressures to raise standards of literacy and to support children with difficulties, and the establishment of a prescribed curriculum for young children. In particular, we focus on the blend and clash of national educational policy ideals in areas related to literacy and children who have been categorised as having ‘special educational needs’, and how these have influenced the development of the Early Literacy Support Programme (ELS) (DfES, 2001a; 2001b). This is a programme set up by the Department for Education and Science in England for children in Year 1, aged 5 to 6 years old. 相似文献

This study explores the impact of an urban ecology program on participating middle school students?? understanding of science and pro-environmental attitudes and behaviors. We gathered pre and post survey data from four classes and found significant gains in scientific knowledge, but no significant changes in student beliefs regarding the environment. We interviewed 12 students to better understand their beliefs. Although student responses showed they had learned discrete content knowledge, they lacked any ecological understanding of the environment and had mixed perceptions of the course??s relevance in their lives. Students reported doing pro-environmental behaviors, but overwhelmingly contributed such actions to influences other than the urban ecology course. Analyses indicated a disconnect between the course, the environment, and the impact on the students?? lives. Consequently, this suggests the importance of recognizing the implications of context, culture, and identity development of urban youth. Perhaps by providing explicit connections and skills in urban environmental programs through engaging students in environmental scientific investigations that stem from their own issues and questions can increase student engagement, motivation, and self-efficacy of environmental issues. 相似文献

This study examines the relationship between Singaporean college students'attitude toward Americans and their exposure to U.S. exported entertainment media. The 328 Singaporean college student participants expressed relatively neutral attitudes toward Americans and reported high consumption of U.S. entertainment media (movies, television shows, magazines, music). Exposure to American media was found to correlate positively with student attitudes toward Americans. In contrast to some media critics' contention that exposure to U.S. media fosters negative attitudes among citizens of other countries, this study suggests that U.S. entertainment may influence attitude toward Americans in a positive direction. 相似文献
