The purpose of the experiments was to determine the automatic use of large or small word reading units in young readers in
the absence of word decoding strategies. Picture-word Stroop interference was examined from four types of conflicting labels:
(a) words containing both highly predictable grapheme–phoneme correspondence (GPC) units and highly consistent rime units
(henceforth, Hi-GPC + Hi-Rime); (b) words with highly predictable GPC units and less consistent rime units (Hi-GPC + Lo-Rime);
(c) words with low predictability GPC units and highly consistent rime units (Low GPC + High Rime); (d) nonwords that contained
both highly predictable GPC and highly consistent rime units. Naming time for pictures containing these labels was compared
against that for pictures with random letter strings or no labels. In Experiment 1, Stroop interference was examined in first,
second, and third grade children to determine whether there was developmental change in the presence of rime or GPC interference.
In Experiment 2, Stroop interference was examined as a function of relative reading skill in first grade children. In Experiment
3, Stroop interference in adults was compared to the use of rime or GPC pronunciation strategies for nonword reading. In all
experiments, Stroop interference in picture naming was longer for pictures with highly predictable GPC unit labels than less
predictable GPC unit labels. However, in Experiment 3, even though adults showed interference from predictable GPC units in
the Stroop task, they always preferred rime pronunciation for ambiguous nonwords in the nonword reading task. It is argued
that the current experiments provide evidence for a flexible units model.
The results of this study were presented at the Cognitive Development Society meeting, November 2001, Virginia Beach, VA,
and the American Educational Research Association meeting, April 2004, San Diego, California. 相似文献

This paper deals with the development of a paediatric team approach to the care of children in the 70 bed paediatric unit in the Royal Hobart Hospital in Tasmania, Australia, and describes the measures used to help children and their parents adapt to life in hospital with a limited budget. The staff includes paediatricians and pediatric surgeon, resident staff, nurses, teachers, social worker, physiotherapist and pharmacist. There are no visiting hours but the wards are open to parents and relatives at any time. Parents are encouraged to stay in hospital and their accommodation is either in flats at the end of wards or in single or double bed wards using foldup beds. Each young child has a personal details form completed and placed on the end of the cot allowing a nurse to discover likes, dislikes, methods of feeding and sleeping, etc. Parents are asked to complete questionnaires at the time of the child's discharge, asking for their assessment of the standards of care their child received. Playleaders are rostered for evenings and weekends and they work with, and direct Red Cross volunteer ladies. Two full-time teachers cooperate with the child's school in maintaining the child's educational progress. Volunteer visitors entertain children whose relatives are unable to visit or stay in hospital. The methods used to raise the standards of paediatric nursing are also described. Community groups, particularly kindergarten and primary school children, are encouraged to visit the paediatric unit and each group is usually given a brief health education talk by a member of staff. 相似文献

新中国成立后,我国在城市基层社会逐步建立了以“单位制”为主,以基层地区管理(街居制)为辅的管理体制。随着我国经济转轨和社会转型,单位制逐渐被打破,街居制也面临着诸多困境,为解决社会中出现的问题和矛盾,社区制就应运而生。在我国城市社区管理体制嬗变中,社区中介组织也随之发展,并发挥着重要作用,因此加强社区中介组织的培育,促进我国城市社区管理体制的改革与完善,是我国城市社区建设的一项重要内容。 相似文献

First,Do No Harm: How Routine Interventions,Common Restrictions,and the Organization of Our Health-Care System Affect the Health of Mothers and Newborns 下载免费PDF全文
Amy M. Romano 《The Journal of perinatal education》2009,18(3):58-62
In this column, the author reprises recent selections from the Lamaze International research blog, Science & Sensibility. Each selection discusses a new study that demonstrates the “First, do no harm” principle in a different way. New research on the potentially harmful effects of intravenous lines demonstrates that refraining from routine interventions in labor protects the safety of women and babies. A new systematic review of movement and position changes in labor shows that eliminating unfounded restrictions also protects maternal and infant health and well-being. Finally, a study of patterns of use of neonatal intensive care units reveals how the organization of the maternity care system itself can affect the health outcomes of its beneficiaries. 相似文献
