Hemispheric laterality in music and math

Hemispheric laterality may be a useful concept in teaching, learning, training, and in understanding more about human development. To address this issue, a measure of hemispheric laterality was compared to musical and mathematical ability. The Human Information Processing Survey (HIPS) instrument, designed to measure hemispheric laterality, was administered to 101 participants who were then asked to provide a measure of their conceptual aptitude for mathematics and music. Scores were then compared through canonical correlation to test the hypothesis that perceived mathematical ability may be explained by left-brain hemisphere preference and musical by the right hemisphere. A relatively strong correlation was found between music ability and right-brain hemisphere preference. A relationship between math and left-brain hemisphere preference or integrated brain processing scores was found to be marginal. Ramifications to learning are discussed.     

Influence of upright versus time trial cycling position on determination of critical power and W′ in trained cyclists

Body position is known to alter power production and affect cycling performance. The aim of this study was to compare mechanical power output in two riding positions, and to calculate the effects on critical power (CP) and W′ estimates. Seven trained cyclists completed three peak power output efforts and three fixed-duration trial (3-, 5- and 12-min) riding with their hands on the brake lever hoods (BLH), or in a time trial position (TTP). A repeated-measures analysis of variance showed that mean power output during the 5-min trial was significantly different between BLH and TTP positions, resulting in a significantly lower estimate of CP, but not W′, for the TTP trial. In addition, TTP decreased the performance during each trial and increased the percentage difference between BLH and TTP with greater trial duration. There were no differences in pedal cadence or heart rate during the 3-min trial; however, TTP results for the 12-min trial showed a significant fall in pedal cadence and a significant rise in heart rate. The findings suggest that cycling position affects power output and influences consequent CP values. Therefore, cyclists and coaches should consider the cycling position used when calculating CP.     

Literacy and life skills education for vulnerable youth: What policy makers can do

In countries with a high concentration of youth with low literacy levels, the policy and programming task related to education and training is particularly daunting. This note briefly presents policies and practices which have been put in place to provide vulnerable youth with literacy and life skills education. It is based on a multi-country research study undertaken by the UNESCO Institute for Lifelong Learning (UIL) in cooperation with the Department of Foreign Affairs, Trade and Development Canada (DFATD Canada; previously Canadian International Development Agency, CIDA), and on subsequent policy dialogue forums with policy makers, practitioners, researchers and youth representatives held in Africa, the Arab region and Asia. Built on this review of existing policies and their implementation, this note provides lessons for innovative practices and suggests six concrete ways to address the needs of vulnerable youth through literacy and life skills education.
