Name-writing proficiency, not length of name, is associated with preschool children's emergent literacy skills     

Puranik CS  Lonigan CJ 《Early childhood research quarterly》2012,27(2):284-294

The goals of this study were twofold: first, to examine whether preschool children's name-writing proficiency differentiated them on other emergent reading and writing tasks, and second, to examine the effect of name length on preschool children's emergent literacy skills including alphabet knowledge and spelling. In study 1, a range of emergent literacy tasks was administered to 296 preschool children aged 4-5 years. The more advanced name writers outperformed the less advanced name writers on all emergent literacy measures. Furthermore, children with longer names did not show superior performance compared to children with shorter names. In study 2, four measures of alphabet knowledge and spelling were administered to 104 preschool children. Once again, the more advanced name writers outperformed the less advanced name writers on the alphabet knowledge and spelling measures. Results indicated that having longer names did not translate into an advantage on the alphabet knowledge and spelling tasks. Name writing proficiency, not length of name appears to be associated with preschool children's developing emergent literacy skills. Name writing reflects knowledge of some letters rather than a broader knowledge of letters that may be needed to support early spelling.  相似文献

Curriculum Design and Epistemic Ascent     

Christopher Winch 《Journal of Philosophy of Education》2013,47(1):128-146

Three kinds of knowledge usually recognised by epistemologists are identified and their relevance for curriculum design is discussed. These are: propositional knowledge, know‐how and knowledge by acquaintance. The inferential nature of propositional knowledge is argued for and it is suggested that propositional knowledge in fact presupposes the ability to know how to make appropriate inferences within a body of knowledge, whether systematic or unsystematic. This thesis is developed along lines suggested in the earlier work of Paul Hirst. The different kinds of know‐how and their relationships are discussed and it is suggested that they occupy different places and different relationships in any curricular hierarchy. The changing role that knowledge by acquaintance plays within this hierarchy is also discussed. Implications of this account for the current National Curriculum and for curriculum design more generally are discussed, looking at History, Science and Design Technology as examples.  相似文献

The perceived impacts of e-government on U.S. cities: A survey of Florida and Texas City managers     

Christopher G. Reddick  Howard A. Frank 《Government Information Quarterly》2007

This study examines the perceived impacts of electronic government or e-government adoption on U.S. cities. This research conducted a survey of Texas and Florida city managers in the fall of 2005 to find out their opinions on the impact of e-government on their city government. The results indicated that e-government is having a positive impact on management, stakeholder involvement, needs and collaboration, and procurement in American cities. There are, however, concerns over spam or unsolicited e-mail and the ability of e-government to reduce the level of staffing. The results of this study imply that, according to city managers' perceptions, e-government adoption in American city governments is positively viewed as having an impact on their organizations and communities.  相似文献

Maximal-intensity isometric and dynamic exercise performance after eccentric muscle actions   总被引：3，自引：2，他引：1  

Byrne C  Eston R 《Journal of sports sciences》2002,20(12):951-959

A well-documented observation after eccentric exercise is a reduction in maximal voluntary force. However, little is known about the ability to maintain maximal isometric force or generate and maintain dynamic peak power. These aspects of muscle function were studied in seven participants (5 males, 2 females). Knee extensor isometric strength and rate of fatigue were assessed by a sustained 60 s maximal voluntary contraction at 80 degrees and 40 degrees knee flexion, corresponding to an optimal and a shortened muscle length, respectively. Dynamic peak power and rate of fatigue were assessed during a 30 s Wingate cycle test. Plasma creatine kinase was measured from a fingertip blood sample. These variables were measured before, 1 h after and 1, 2, 3 and 7 days after 100 repetitions of the eccentric phase of the barbell squat exercise (10 sets x 10 reps at 80% concentric one-repetition maximum). Eccentric exercise resulted in elevations in creatine kinase activity above baseline (274+/-109 U x l(-1); mean +/- s(x)) after 1 h (506+/-116 U x l(-1), P < 0.05) and 1 day (808+/-117 U x l(-1), P < 0.05). Isometric strength was reduced (P < 0.05) for 7 days (35% at 1 h, 5% at day 7) and the rate of fatigue was lower (P < 0.05) for 3 days at 80 degrees and for 1 day at 40 degrees. Wingate peak power was reduced to a lesser extent (P < 0.05) than isometric strength at 1 h (13%) and, although the time course of recovery was equal, the two variables differed in their pattern of recovery. Eccentrically exercised muscle was characterized by an inability to generate high force and power, but an improved ability to maintain force and power. Such functional outcomes are consistent with the proposition that type II fibres are selectively recruited or damaged during eccentric exercise.  相似文献   

Anxiety, arousal and visual attention: a mechanistic account of performance variability     

Janelle CM 《Journal of sports sciences》2002,20(3):237-251

Despite extensive research devoted to determining the nature of the relationship between stress and performance, there has been little systematic examination of the mechanisms underlying this relationship. Recently, researchers have begun to empirically address the attentional mechanisms underlying theoretical accounts of how stress, anxiety and arousal influence performance. Given the critical role of visual attention to sport expertise, this paper focuses primarily on literature dealing with how visual cues are differentially identified and processed when performers are anxious. Emerging evidence indicates that gaze behaviour tendencies are reliably altered when performers are anxious, leading to inefficient and often ineffective search strategies. Alterations of these visual search indices are addressed in the context of both self-paced and externally paced sports events. Recommendations concerning the utility of perceptual training programmes and how these training programmes might be used as anxiety regulation interventions are discussed. The theoretical implications and directions for future research are also addressed.  相似文献
