Behavioural Evidence

Many species of typically diurnal songbirds experience sleep loss during the migratory seasons owing to their nocturnal migrations. However, despite substantial loss of sleep, nocturnally migrating songbirds continue to function normally with no observable effect on their behaviour. It is unclear if and how avian migrants compensate for sleep loss. Recent behavioural evidence suggests that some species may compensate for lost night-time sleep with short, uni- and bilateral ‘micro-naps’ during the day. We provide electrophysiological evidence that short episodes of sleep-like daytime behaviour (approx. 12 s) are accompanied by sleep-like changes in brain activity in an avian migrant. Furthermore, we present evidence that part of this physiological brain response manifests itself as unihemispheric sleep, a state during which one brain hemisphere is asleep while the other hemisphere remains essentially awake. Episodes of daytime sleep may represent a potent adaptation to the challenges of avian migration and offer a plausible explanation for the resilience to sleep loss in nocturnal migrants.

This study aimed to discuss the names of judgment day in the Qur'an through cognitive semantic approach and the values of spiritual education. Through the cognitive semantic approach, the conception of meaning to describe the judgment day in the Qur’an was formulated by mapping the meaning resulted from the source domain (Sd) to target domain (Sd). To show and compare references in (Sd) to (Td), referential technique was used. From organizing (Sd) to (Td) on metaphorical expressions which showed the judgment day in the Qur'an, the conceptions of the meaning of state, time, movement, and change were generated. The studies on the names of judgment day in the Qur'an influence the value of moral education, which is able to increase faith in God, observe nature and its big symptoms, create good character between God and man, and believe in God’s noble character.
