Brain injury: Assessment of hemineglect occurence and of attentional deficit through cancellation tasks

Hemineglect (HN) is a widely studied syndrome after unilateral lesions due to stroke. However, although there are some studies with HN rehabilitation of posttraumatic brain injury (TBI), there seems to be no published data about the prevalence of HN in TBI through cancellation tasks. Thus, the objective of this study was to characterize the occurrence of this syndrome and of attentional deficits in patients with TBI by means of the Bells Test and of a line cancellation task. The sample was comprised of 21 patients with TBI and 21 healthy controls matched by education, age and frequency of written language habits. There was a poorer performance of patients with TBI with a greater number of omissions on the left side and lower speed processing. In addition, suggestive signs of HN were found in 38 % of the sample of TBI patients. More research is needed to characterize clinical syndromes regarding the occurrence of HN after a TBI through the traditionally known cancellation paradigm.

La Diplomacia del Jazz como una estrategia de política exterior de Estados Unidos durante la Guerra Fría

En aras de contener el comunismo y expandir la cultura norteamericana y los valores de democracia y libertad, Estados Unidos lanzó una estrategia de política exterior denominada la Diplomacia del Jazz, que consistía en promocionar internacionalmente el jazz mediante dos artificios: primero, la celebración de conciertos de los intérpretes más representativos de este género en diferentes partes del mundo; y segundo, la trasmisión de programas radiales sobre jazz en emisoras de difusión internacional y así poder mostrar la “superioridad” cultural de su país en detrimento de la otra superpotencia, la Unión Soviética. De este modo, la presente monografía tiene como fin estudiar de qué manera se instrumentalizó dicha estrategia como un medio para proyectar positivamente la imagen de los EEUU durante la Guerra Fría, concretamente entre 1954 y 1968, a partir de la teoría del realismo progresivo de Joseph Nye.
