This study examined the effects of a syllable-based reading intervention for German second graders who demonstrated difficulties in the recognition of written words. The intervention focused on fostering word reading via syllable segmentation. The materials consisted of the 500 most frequent syllables typically read by 6- to 8-year-old children. The aims were to practice phonological recoding, consolidate orthographic representations of syllables, and routinize the access to these representations. Compared to children randomly assigned to a wait-list group, poor readers in the treatment condition showed significant improvements in standardized measures of phonological recoding, direct word recognition, and text-based reading comprehension after the 24-session intervention. Poor readers in the treatment condition also showed greater improvements in development of word recognition compared to children with efficient word recognition skills. The results provide evidence that a syllable-based reading intervention is a promising approach to increase struggling readers’ word recognition skills, which in turn will improve their reading comprehension. 相似文献

The article presents an analysis of 93 essays written in an upper secondary school context. The essays were collected in relation to a larger research project, which went on for 5 years in a Danish upper secondary school (2010–2015). The material represents both genders and the students are 15–17 years old. We deploy a theoretical framework taken from Norbert Elias’ notion on established-outsider relations [Elias, N., &; Scotson, J. L. (1994 [1965]). The established and the outsiders. London: SAGE] as well as his use of personal pronouns [Elias, N. (1978). What is sociology? London: Hutchinson, Elias, N. (2001). The society of individuals. New York: The Continuum International Publishing Group] in illustrating how people negotiate, position and navigate within figurational contexts [Elias, N. (1994 [1939]). The civilizing proces. Oxford: Blackwell.]. We do this in an effort to interpret how young people negotiate ‘we-I-relations’ when it comes to their sporting identity. Elias’ processual framework provides a tool for a much needed analysis of how young people continually orientate and develop their sense of selves. The web of human interdependencies and processes of change are key words when it comes to understanding the social practices and doings of the students’ constructions of self-steering. What social scientists may see as laziness and drop-outs of sports [Seippel, Ø. (2016). Prek, vekker og kjedelig? Trening og mening blant ungdom: 1985–2013. In Ø. Seippel, M. K. Sisjord, &; Å Strandbu (Eds.), Ungdom og Idrett. Oslo: Cappelen Damm Akademisk] can in the essays of students be analysed as a struggle for group connectedness and social inclusion in the classroom. The results of our research show that identity is a multiple concept and an ongoing process of emotional work [Elias, N. (1987). On human beings and their emotions: A process-sociological essay. Theory Culture Society, 4, 339–361], but also a power balance of playing and presenting what is imagined as the right performance as not being shamed as outcasts. 相似文献

从人力资本和社会资本的视角出发,以316名中国退役运动员为研究对象,探讨这2种资本对退役运动员收入的影响,结果显示:①中国退役运动员的收入差异较大,平均收入状况不容乐观;②在人力资本的各观测变量中,运动等级、受教育程度、身体健康状况和职业技能培训依次对退役运动员收入产生影响;③在社会资本各观测变量中,弱关系和网络异质性对退役运动员收入影响显著;④人力资本有助于退役运动员进入中等收入群体,社会资本有助于其进入高收入群体;⑤人力资本和社会资本对退役运动员的收入提升作用显著,且人力资本作用高于社会资本。基于此,从政府和个体层面提出提升退役运动员人力资本和社会资本的建议。 相似文献

针对多旋翼无人机目标的识别问题,提出一种基于伽柏(Gabor)变换的瞬时频率估计与快速傅里叶变换(FFT)相结合的微多普勒特征提取算法。首先建立多旋翼无人机旋翼回波模型,并通过仿真分析叶片数目、旋翼转速和初始相位等参数对微多普勒特征的影响,利用Gabor变换得到时频特征。在此基础上通过瞬时频率极大值法提取微多普勒频率,并对瞬时频率采用FFT提取旋翼数和转动频率,从而获得叶片长度估计值。实测数据验证了该算法较为准确地提取无人机的微多普勒参数。 相似文献

人性假设与人力资源管理 总被引:3,自引:0,他引:3
人力资源管理的基础是人性假设 ,人性假设对人力资源管理具有导向作用。对人的认识不同 ,也就是人性假设不同 ,会有不同的选人用人政策 ,会有不同的人力资源管理方式。 相似文献
