Given sufficient exposure to stimulus presentation, the oculomotor system generates a representation of the stimulus characteristics, which is then used to predict the upcoming target motion. In addition to compensating for the perceptual-motor delay, these predictive processes perpetuate eye motion during a transient occlusion and compensate for the loss of visual input. At present, however, i...

International Family Planning Perspectives 32(3) Digests

International Family Planning Perspectives Women who have undergone female genital mutilation have a higher risk for adverse obstetric outcomes than women who have not, and the risks seem to be greater with more severe mutilation, according to the first large-scale prospective study of the effects of female genital mutilation on maternal and neonatal outcomes.1 Relative to women who have not un...

Exotic Red-billed Leiothrix Leiothrix lutea numbers have increased in southern, western and central part of Japan since the early 1980’s. Unlike most naturalized birds, this species mainly breeds in natural deciduous forests. We researched the breeding bird density in a deciduous forest on Mt. Tsukuba (877 m), a major breeding area of leiothrix in central Japan, in 1994 and 1995. Leiothrix bred...
