Suprasegmental Phonology Development and Reading Acquisition: A Longitudinal Study

Previous studies implicate suprasegmental phonology in reading acquisition. However, little is known about how suprasegmental sensitivity develops or how it contributes to reading. Here, 130 Spanish primary-school children participated in this 2-year longitudinal study. Nonlinguistic rhythm, lexical-stress sensitivity and metrical-stress sensitivity, along with phonological awareness, vocabulary, nonverbal intelligence, and reading aloud, were assessed on five occasions. Results suggest that prosody abilities have different developmental trajectories and that prosody explains unique variance in reading beyond that explained by other factors. There was some evidence that the contribution of each prosody skill occurred at different phases in reading development. Nonlinguistic rhythm, lexical-stress sensitivity, and metrical-stress sensitivity assessed at the end of kindergarten, the start of Grade 1, and the end of Grade 1, respectively, predicted reading performance 6 months later. Nevertheless, sample size and reliability temper the conclusions that can be made. The implications of prosody skills for literacy development are discussed.     

Comparison of different theoretical models estimating peak power output and maximal oxygen uptake in trained and elite triathletes and endurance cyclists in the velodrome

Abstract

The primary objective of this study was to examine the relationship between heart rate intensity and pedometer step counts in adolescents. To determine cardiorespiratory fitness, 106 participants (47 boys, 59 girls, mean age 14.2 years, s = 0.8) completed the Queen's College Step Test and were classified as having low, moderate or high cardiorespiratory fitness. Adolescents also completed a 10-min treadmill trial while wearing a pedometer and heart rate monitor. The participants were instructed to maintain their heart rate between 65 and 75% of their maximum heart rate while running or walking on a treadmill. A heart rate of 65–75% maximum was associated with 146 steps per minute (s = 22) in boys and 137 steps per minute (s = 22) in girls. Results of analysis of variance indicated that there was a main effect for level of fitness (F _2,102 = 9.36, P < 0.001). The correlation between mean steps per minute and estimated maximum oxygen consumption was statistically significant (r = 0.44, P < 0.001). The results from this study suggest that a step rate of 130 steps per minute is equal to 65–75% maximum heart rate in low-fit adolescents and achieving 130 steps per minute could be used as an initial goal to improve fitness.

Evaluating Children’s Participation in SEN Procedures: Lessons for educational psychologists

This paper reports the findings from a study of the participation of children with special educational needs (SEN) in decision‐making about their needs in a sample of mainstream schools which were self‐selected for having promising practices. The findings show promising practices in eliciting views, the importance of a school participation ethos and inconsistencies between policy and practices. The study also illustrates the complexity and challenge of consulting and sharing decision making with children and young people. The outcomes are discussed in terms of educational psychologists becoming involved in research and in supporting whole school developments of participation practices.     

A tale of Wootz steel

The extraordinary romance and thrilling adventure associated with the tale of wootz steel shows how Indian metallurgists were the world leaders in antiquity in the manufacture of this legendary high-grade steel. In many ways this material was brought to global attention by the writings of Cyril Stanley Smith. Modern metallurgy and materials science rest on the foundation built by the study of this steel during the past three centuries.
