Xinjiang’s geographies in motion

Starting from the idea that places are socially constructed, this essay explores how place is established and lived in Xinjiang by the members of the area’s two largest ethnicities, the Uyghur and the Han. This paper demonstrates that there are differences in the ways Han and Uyghur imagine and ‘live’ Xinjiang. At the same time it asserts that Uyghur and Han do not establish distinct spatial relationships just because of their ethnicity, but also to enhance ethnic solidarity and boundaries vis-à-vis the other. This essay also demonstrates that places are historically contingent, and it discusses the ways in which the influx of Han temporary migrants and settlers—and Han capital—has generated new layers of spatial meaning and new power differentials.

La educación física en los primeros años del franquismo (1939-1945)

La Educación Física tuvo una configuración específica en la instauración del régimen franquista, por intereses ideológicos y políticos, que determinó sus características y evolución. En este estudio se aportan hechos y circunstancias para una mejor comprensión de las razones que llevaron a su dependencia del aparato político del Movimiento, separándola del ámbito educativo al que, en buena lógica, debió ser adscrita.

Perceptual learning in motion discrimination that generalizes across motion directions

When human subjects discriminate motion directions of two visual stimuli, their discrimination improves with practice. This improved performance has been found to be specific to the practiced directions and does not transfer to new motion directions. Indeed, such stimulus-specific learning has become a trademark finding in almost all perceptual learning studies and has been used to infer the loci of learning in the brain. For example, learning in motion discrimination has been inferred to occur in the visual area MT (medial temporal cortex) of primates, where neurons are selectively tuned to motion directions. However, such motion discrimination task is extremely difficult, as is typical of most perceptual learning tasks. When the difficulty is moderately reduced, learning transfers to new motion directions. This result challenges the idea of using simple visual stimuli to infer the locus of learning in low-level visual processes and suggests that higher-level processing is essential even in “simple” perceptual learning tasks.
