Time gap analysis by the topic model-based temporal technique     

《Journal of Informetrics》2014,8(3):776-790

This study proposes a temporal analysis method to utilize heterogeneous resources such as papers, patents, and web news articles in an integrated manner. We analyzed the time gap phenomena between three resources and two academic areas by conducting text mining-based content analysis. To this end, a topic modeling technique, Latent Dirichlet Allocation (LDA) was used to estimate the optimal time gaps among three resources (papers, patents, and web news articles) in two research domains. The contributions of this study are summarized as follows: firstly, we propose a new temporal analysis method to understand the content characteristics and trends of heterogeneous multiple resources in an integrated manner. We applied it to measure the exact time intervals between academic areas by understanding the time gap phenomena. The results of temporal analysis showed that the resources of the medical field had more up-to-date property than those of the computer field, and thus prompter disclosure to the public. Secondly, we adopted a power-law exponent measurement and content analysis to evaluate the proposed method. With the proposed method, we demonstrate how to analyze heterogeneous resources more precisely and comprehensively.  相似文献   

Comparison of Alternative Channels in Cross Media Publishing     

Andreas Veglis 《Publishing Research Quarterly》2008,24(2):111-123

This paper attempts a direct comparison of the available alternative channels that can be employed in a cross media publishing scheme. More precisely it examines the content, the publishing speed, and the rhythm of the publishing channels. Interesting conclusions are drawn concerning the characteristics of each channel. A new publishing channel is proposed in order to allow newspapers to directly compete with radio and TV channels.  相似文献

Sex differences in self‐estimation of multiple intelligences among Portuguese adolescents     

Félix Neto  Fátima Ruiz  Adrian Furnham 《High Ability Studies》2008,19(2):189-204

This study investigated the relationship among sex, attitude toward intelligence, and self‐estimation of multiple intelligences for self and parents among Portuguese adolescents in secondary schools. Two hundred and forty‐two adolescents estimated their own and their parents' IQ scores on each of Gardner's 10 multiple intelligences: verbal (linguistic), logical (mathematical), spatial, musical, body‐kinesthetic, interpersonal, intrapersonal, existential, spiritual, and naturalistic. They also answered six simple questions concerning intelligence and intelligence tests. There were various sex differences in self‐estimated IQ: males rated themselves higher on overall, mathematical, spatial, intrapersonal, spiritual, and naturalistic IQ compared with females. Multiple regressions indicated that verbal, logical, and intrapersonal intelligence were significant predictors for self and parents overall IQ estimations. Factor analysis of the 10, the 8, and the 7 self‐estimates scores did not confirm Gardner's classification of multiple intelligences. Males were more likely to believe in sex differences in intelligence than females. Results are discussed in terms of the growing literature in the self‐estimates of intelligence, as well as limitations of that approach.  相似文献   

新课程下语文阅读教学中“度”之探微     

黄乃佳 《钦州学院学报》2008,23(5)

在目前语文阅读教学中,出现了一些把握“无度”的做法,不但影响教学效果,而且会影响语文课程改革的顺利推进。因此,切实把握阅读教学中的“度”,那就是：教学目标要适度;课堂提问要适度;多元解读要适度;拓展延伸要适度。  相似文献

A tale of two tests: The role of topic and general academic knowledge in traditional versus contemporary scenario-based reading     

《Learning and Instruction》2021

We compared high school students’ performance in a traditional comprehension assessment requiring them to identify key information and draw inferences from single texts, and a scenario-based assessment (SBA) requiring them to integrate, evaluate and apply information across multiple sources. Both assessments focused on a non-academic topic. Performance on the two assessments were moderately correlated (r = 0.57), but the SBA was more difficult (Study 1; n = 342). The two assessments similarly depended on basic reading skills but diverged in the relation to academic knowledge and (non-academic) topic knowledge (Study 2; n = 1107). Academic knowledge was highly predictive of traditional comprehension, but less so for SBA. Topic knowledge was more predictive of SBA than traditional comprehension. Thus, the two assessments tap into similar constructs related to comprehension; however, the level of topic knowledge is more important for performance on scenario-based, multiple-source reading tasks, whereas academic knowledge is more important for traditional reading comprehension tasks.  相似文献
