In 1145–1146, Sayf al-Dawla returned to al-Andalus to create an independent kingdom and return the Banū Hūd of Zaragoza to prominence. His task was a difficult one, not least because he’d spent a decade serving the Christian king Alfonso VII. After a year of campaigning, Sayf al-Dawla secured a base of support in Murcia. However, he died shortly after his coronation in a battle with Christian allies who were allegedly sent by Alfonso to help him. In addition to providing an explanation for the battle and his death, the article examines how Sayf al-Dawla promoted the legitimacy of his state through his coinage, adherence to Andalusī traditions, and a network of fellow exiles. It interprets the Zaragozan ?ā’ifa as a moveable faction rather than a fixed geographical entity and connects Sayf al-Dawla’s kingdom to later movements to demonstrate how his actions preserved the Banū Hūd’s prestige in Andalusī imaginations. 相似文献

The aims of this experiment were to determine whether there are differences between the sexes in the three-dimensional angular rotations of the lumbo-pelvic-hip complex during running and, if such differences exist, to establish whether factors other than sex can explain the observed differences. A cohort of 44 non-injured runners (22 males, 22 females) who usually ran more than 20 km per week were voluntarily recruited. All trials were conducted on a treadmill at a running speed of 4.0 m x s(-1). Reflective markers were placed over specific anatomical landmarks of the thoraco-lumbar spine, pelvis and femur. Data were captured using a VICON motion analysis system. Females tended to display a greater peak-to-peak oscillation for most of the angular rotations. An offset was the main difference between the male and female group mean waveforms for pelvis anterior-posterior tilt. Forward stepwise regression analysis revealed that sex was the most common variable related to the amplitudes of the angular rotations. Given these results, sport scientists conducting future biomechanical studies using angular data to test hypotheses are advised to be extremely cautious about averaging across male and female participants. 相似文献
