This paper reports research on the effects of variations in injection velocity and permeability on the heat transfer and flow
through a highly porous medium between two horizontal parallel plates situated at constant distance with constant suction
by the upper plate. Due to this type of variation in injection velocity and in permeability the flow becomes three dimensional.
The governing equations are solved by adopting complex variable notations to obtain the expressions for the velocity and temperature
field. The skin-friction along the main flow direction and rate of heat transfer are discussed with the help of graphs. 相似文献

The silent reading fluency is not an observable behaviour and, therefore, its evaluation is perceived as more challenging and less reliable than oral reading fluency. The present research is aimed to measure the silent reading speed in a sample of proficient students, assessed by an original silent reading fluency task, based on behavioural indicators of the silent reading speed. A total of 325 high school and university skilled students (age range 14–23 years) have been assessed using 3 tasks aimed to evaluate the oral reading speed (lists of words, lists of pseudowords and narrative text) and one task aimed to measure the silent reading speed. The average silent reading speed in our sample was around 12.5 syll/sec, almost double than the oral reading speed rate. The silent reading speed had an increase from 9.13 to 12.38 syll/sec from the first year of high school (ninth grade) to the fifth year of University. Conversely, the oral reading speed remained substantially unchanged for the entire academic course. Our results showed that the reading fluency in silent mode tends to increase up to the last years of University and it may be considered the most rapid and efficient reading mode. This study highlights the importance of including both silent and oral reading modes in the assessment of the older students and young adults, since silent reading is the main reading mode for proficient readers. 相似文献

This article examines the historical fantasy world created by Joan Aiken in the eleven volumes of her Wolves of Willoughby Chase series. In particular it looks at her subversion of historical reality by the creation of an alternative yet recognisable representation of our own world, using a wide range of events, and the remoulding of aspects of language and geography. It also discusses her reasons for writing in this form and explores the character of Dido Twite as heroine and major raison dtre of the series.This revised version was published online in May 2005 with corrections to the article title. 相似文献

The rigours of the past few years have demonstrated the importance of good health literacy levels with the imperative of being able to obtain and interpret information to maintain and improve one's health never more apparent. With this in mind, this issue is focused on consumer health information, the gender and population group differences that exist in information seeking behaviour, the challenges of understanding medical explanations and terminology, and existing criteria to assess and ultimately produce better consumer health information. 相似文献

This study investigates the relationship between working memory and language in young children growing up in a multilingual environment. The aim is to explore whether mechanisms of short-term storage and cognitive control hold similar relations to emerging language skills and to investigate if potential links are mediated by related cognitive abilities. A sample of 119 Luxembourgish 6-year-olds completed several assessments of working memory (complex and simple span), native and foreign vocabulary, syntax, reading, rhyme awareness, and fluid intelligence. Results showed that short-term storage and cognitive control manifested differential links with developing language abilities: Whereas verbal short-term storage was specifically linked to vocabulary; cognitive control manifested unique and robust links with syntax and early reading development. The study suggests that in young children the working memory system is composed of separate but interacting components corresponding to short-term storage and cognitive control that can be distinguished by the roles they play in supporting language acquisition. 相似文献

This meta-analysis integrates 296 effect sizes reported in eye-tracking research on expertise differences in the comprehension
of visualizations. Three theories were evaluated: Ericsson and Kintsch’s (Psychol Rev 102:211–245, 1995) theory of long-term working memory, Haider and Frensch’s (J Exp Psychol Learn Mem Cognit 25:172–190, 1999) information-reduction hypothesis, and the holistic model of image perception of Kundel et al. (Radiology 242:396–402, 2007). Eye movement and performance data were cumulated from 819 experts, 187 intermediates, and 893 novices. In support of the
evaluated theories, experts, when compared with non-experts, had shorter fixation durations, more fixations on task-relevant
areas, and fewer fixations on task-redundant areas; experts also had longer saccades and shorter times to first fixate relevant
information, owing to superiority in parafoveal processing and selective attention allocation. Eye movements, reaction time,
and performance accuracy were moderated by characteristics of visualization (dynamics, realism, dimensionality, modality,
and text annotation), task (complexity, time-on-task, and task control), and domain (sports, medicine, transportation, other).
These findings are discussed in terms of their implications for theories of visual expertise in professional domains and their
significance for the design of learning environments. 相似文献

Bullying in schools has been identified as a serious and complex worldwide problem associated with negative short- and long-term
effects on children’s psychosocial adjustment (Smith 1999; Ttofi and Farrington, Aggressive Behav 34(4):352–368, 2008). Entering kindergarten is a crucial developmental step in many children’s lives mainly because it is within this context
where they participate, for the first time, as members in a stable peer group and well-organized team activities. Consequently,
preschool may be the first context beyond the home environment where children’s difficulties in social interactions with peers
can be primarily detected and assessed by adults and professionals. This paper reviews recent empirical evidence over the
nature and different aspects of bullying among preschool children. Recent findings concerning the development of preschool
bullying and its prevalence, family and genetic factors, gender and age differences, participant and peripheral roles, school
context, methodological issues, and prevention policies are reviewed while directions for future research are addressed. 相似文献
