It has been suggested that a low-glycaemic index (GI) breakfast may be beneficial for some elements of cognitive function (e.g. memory and attention), but the effects are not clear, especially in adolescents. Thus, the aim of the present study was to examine the effects of a low-GI breakfast, a high-GI breakfast and breakfast omission on cognitive function(More)
There has been much interest in recent years in the way in which global relations on structures emerge. The mathematics underlying such emergence has intimate connections with iterations of algorithms and complexity related to simple computer programs. Examples of the phenomena involved range from the emergence of natural laws in the physical universe, to(More)
This study examined the effects of breakfast consumption on cognitive function, mood and blood glucose concentration in adolescent schoolchildren. With the institution's ethical advisory committee approval, 96 adolescents (12 to 15 years old) completed two randomly assigned trials (one following breakfast consumption and one following breakfast omission),(More)
The aim of the present study was to examine the combined effects of breakfast glycaemic index (GI) and a mid-morning bout of exercise on adolescents' cognitive function. Participants were randomly allocated to a high or low GI breakfast group in a mixed research design, where each participant completed two experimental trials (exercise and resting).(More)
It is shown that the complete Turing degrees do not form an automor-phism base. A class A A A ⊆ the Turing degrees D D D is an automorphism base (see Lerman [1983]) if and only if any nontrivial automorphism of D D D necessarily moves at least one of its elements — or, equivalently, the global action of any such automorphism is completely determined by that(More)
According to ... [the " one-shot " ] ... view, mathematics would consist of a succession of targets, called problems, which mathematicians would be engaged in shooting down by well-aimed shots. But where do problems come from, and what are they for? If the problems of mathematics were not instrumental in revealing a broader truth, then they would be(More)
Moderate intensity exercise has been shown to enhance cognition in an adolescent population, yet the effect of high-intensity sprint-based exercise remains unknown and was therefore examined in the present study. Following ethical approval and familiarisation, 44 adolescents (12.6 ± 0.6 y) completed an exercise (E) and resting (R) trial in a(More)
