Abstract In an effort to help teacher candidates understand early childhood classroom environments, a website was constructed for use in a foundation in early childhood education course. This website, based on constructivist teaching practices uses technology in a unique way to assist students as they come to know, understand, and use the principles associated with room arrangement and management of early childhood classrooms. 相似文献
AbstractThis study examined changes in the propulsive force and stroke parameters of arm-amputee and able-bodied swimmers during tethered swimming. Eighteen well-trained female swimmers (nine unilateral arm amputees and nine able-bodied) were videotaped performing maximal-effort 30 s front-crawl swims, while attached to a load cell mounted on a pool wall. Tether force, stroke rate, stroke phase durations and inter-arm angle were quantified. The able-bodied group produced significantly higher mean and maximum tether forces than the amputee group. The mean of the intra-cyclic force peaks was very similar for both groups. Mean and maximum tether force had significant negative associations with 100 m swim time, for both groups. Both groups exhibited a similar fatigue index (relative decrease in tether force) during the test, but the amputees had a significantly greater stroke rate decline. A significant positive association between stroke rate decline and fatigue index was obtained for the able-bodied group only. Inter-arm angle and relative phase durations did not change significantly during the test for either group, except the recovery phase duration of the arm amputees, which decreased significantly. This study’s results can contribute to the development of a more evidence-based classification system for swimmers with a disability. 相似文献
Abstract This paper examines the effect of participating in a web-based health programme that promotes personal tracking of high school students’ own measurements of a number of health-related parameters. Danish cross-sectional survey data were used to examine the effects of the health programme on various health measures. Both quantile regression models and standard ordinary least squares (OLS) models were used to explore the correlations between the students’ participation in the health programme and their body mass index (BMI), body fat percentage, aerobic fitness, and well-being. Participation in the health programme increased BMI and aerobic fitness among students with a BMI or an aerobic fitness value ranging from the 25th percentile to the 75th percentile and reduced body fat percentage among students with the highest percentages of body fat. In addition, the health programme led to an increased feeling of wellbeing among students, especially those with high BMI levels and poor aerobic fitness. As the schools participated in the health programme on voluntary basis and at a financial cost to themselves, the positive effects of participation found can only be stated to be valid among students from committed schools. 相似文献
Provides an understanding of the importance of journals in industry and of the types of measures there taken to ensure value for money and a high quality service, and outlines some ways in which publishers can serve industrial users better by recognizing the need for high–quality services, speedy and reliable delivery, and flexibility of service. 相似文献

This chapter of Cultural Trends discusses ways in which war memorials demonstrate changing cultural or societal trends in the UK through their various forms and functions, and through the evolution of memorialisation itself.
It introduces the UK National Inventory of War Memorials, an archive which was established in 1989 and which records details of memorials throughout the UK. The chapter is based on data and detailed examples taken from the 47,000 records currently input on the archive's database and it explores those records to examine memorials commemorating the Boer Wars, First and Second World Wars and the Korean War, in particular.
The first section considers general issues regarding war memorials in the UK ‐ the ways in which memorial styles have changed, and how these reflect changing attitudes towards those who served in the armed forces in the late 19th and 20th centuries.
The second section is about the pragmatics of memorialisation, and focuses on the significance of where memorials are positioned, whether inside or out and within public or private spaces; the increase in secularisation; the geographical spread of memorials; and issues related to urban and rural memorialisation.
The third section considers the evolution of memorials from being a focus for grief for those whose friends and relations’ bodies were not returned, to manifesting veterans groups’ assertions of their identity many years after a conflict. The physical movement of memorials is also covered, ranging from memorials which have been lost or neglected, through to memorials being moved in order to preserve them so that remembrance services can continue. Peaks and troughs of memorialisation through the 20th century are also considered.
To conclude, the fourth section pulls together various threads drawn throughout the chapter, analysing memorials chronologically, geographically, stylistically and in terms of their relative ‘popularity’. 相似文献
