Children with spelling deficits demonstrate significant difficulty using inflectional morphology in their writing. This study investigated whether phonological deficits account for these pronounced difficulties or if they are more accurately explained by limitations in morphological or orthographic awareness. Twenty–six 11—13–year–old children with spelling deficits, 31 younger spelling–level–matched children, and 31 age–matched children were asked to spell a series of verbs with past tense and progressive markers in dictated sentences and in list form. Performance on spelling tasks was compared to performance on phonological, morphological, and orthographic awareness tasks. Results suggest that children with spelling deficits have significant difficulty including inflections as well as spelling inflections and base words. Difficulty was most pronounced in a sentence context. Ability to spell inflectional forms was related to variation in morphological awareness in children with spelling deficits and to variation in orthographic awareness in spelling–level–matched children.  相似文献

This paper discusses the use of systems development research methods in the context of ongoing research that is formulating a specification for a metadata schema registry. The paper extrapolates from this discussion how such methods can be utilized in archival systems research and how such an approach differs from commercial systems engineering. In particular, the paper suggests that adopting a user-centred prototyping approach in a research context allows for exploration of the interplay between theory and practice, advancing the practice, while also offering new insights into theoretical concepts. It argues that these research methods are of increasing interest to the archival profession in order to conceptualise and realise the tools necessary to support recordkeeping and archival processes in digital environments.  相似文献

This study assessed the impact of coworker support on lactating mothers’ breastfeeding self-efficacy after maternity leave. A cross-sectional survey of 1000 working adults assessed effects of perception of fairness, coworkers’ support for breastfeeding colleagues, and ick response on willingness to help mothers needing breaks to pump breastmilk at work. The study also examined how coworker support affected mothers’ self-efficacy to continue breastfeeding. One out of four coworkers showed moderate to strong stigma, saw breaks to pump breastmilk as unfair, and showed less intention to help new mothers. These results suggest that while the majority of coworkers are generally supportive, lactating women are likely to encounter disapproving coworkers who may discourage them from continuing to breastfeed. The data showed that the majority of organizations included in this study have only passively fostered mother-friendly workplaces and could do more to encourage employees to be supportive of lactating colleagues.  相似文献

Fitness is an important component of health, and obese adolescents regularly have poor fitness. Unfortunately, few have assessed the impact of community-based lifestyle interventions on multiple components of fitness. The purpose of this study was to assess the impact of participation in a community-based intervention involving adolescents and parents on multiple components of fitness of obese adolescents. In a within-subject, waitlist controlled clinical trial with 12 months follow-up in Western Australia, participants (n = 56) completed multiple fitness measures at baseline, immediately prior to beginning an 8-week intervention and at 3, 6 and 12 months during a maintenance period. Performance on the shuttle walk was improved immediately post-intervention (increase of 42.8 m, 95% CI: 7.5, 78.2) and at 12 months post-intervention (increase of 44.6 m, 95% CI: 1.3, 87.8) compared with pre-intervention. Muscle performance of quadriceps and deltoids were improved post-intervention (increase of 1.1 (95% CI: 0.1, 2.1) kg · F and 1.0 (0.02, 2.1) kg · F, respectively) and all muscle performance measures were improved at 12 months following the intervention. There were no changes in waist circumference. A community-based lifestyle programme such as Curtin University’s Activity, Food and Attitudes Program (CAFAP) may be a viable strategy for improving fitness in overweight adolescents.  相似文献

Teacher competency frameworks comprise a number of competencies that enable a teacher to develop effective teaching practices. However, their conception, value, use and recognition vary widely. Equally, assessment and measurement of such competencies differ across contexts. More recently, a body of research has emerged which focuses the lens of teacher preparation on the inclusion of high leverage practices. The focus of this study is to report a synthesis of the literature pertaining to the ‘core competencies’ and ‘high leverage practices’ selected for inclusion in teacher preparation. A systematic review of the literature was conducted in order to synthesis available evidence. Results are presented in two sections; competency-based approaches; and high leverage practice approaches in teacher preparation. Findings are discussed from the perspective of epistemological and methodological questions emerging from the research and the implications for teacher preparation.  相似文献

Purpose: To describe the results of showing farmer learning videos through different types of volunteers.

Design/Methodology/Approach: Semi-structured interviews with volunteers from different occupational groups in Bangladesh, and a phone survey with 227 respondents.

Findings: Each occupational group acted differently. Shop keepers, tillage service providers, agricultural input and machine dealers reached fairly small audiences. Tea stall owners had large, male audiences. Non-governmental organisations and community-based organisations, reached more women. The cable TV (dish-line) operators showed the videos on local TV, but some were reluctant to do so again. The Union Information Service Centres showed the videos and reached women viewers. Half of the official government extension agents surveyed also showed the videos publically.

Practical Implication: This video featured maize, wheat and rice seeding machinery. Because the machinery is complex and requires hands-on training, this first video aimed to expose tillage and sowing service providers and farmers to the machinery, without trying to teach them how to use it. But some farmers were so interested that they watched the video many times to learn more about the equipment. Before farmers and service providers decide to buy machinery for direct seeding, they still want to see and learn from demonstration plantings, to examine first-hand how the crop behaves when planted with the new equipment.

Originality/Value: Video can be an effective way of sharing high-quality information with a large audience, if properly distributed.  相似文献
