The results obtained in a consecutive series of thirty-seven Pemberton operations for congenital dislocation or subluxation of the hip are reported. Over the period under review, 1967 to 1973, it was the only type of acetabuloplasty employed at Winford. Unless the mandatory concentric reduction could be obtained with ease, preliminary open reduction was favoured, especially in cases of primary ...

Intrinsic motivation has been shown in previous research to lead to better learning. In order to increase intrinsic motivation, REAP, a tutoring system for ESL vocabulary was enhanced to prefer practice readings that match personal interests. In a randomized experiment, students receiving personalized readings indicated higher levels of interest in post-reading questionnaires. Additionally, ove...

The concept of autonomy in the context of language education in Europe had focused on the importance of personal autonomy. It was only recently that cultural influences were taken into consideration in interpreting autonomy. Studies on undergraduates learning ESL (English as a Second Language) in public universities in Malaysia revealed that the students were basically teacher-centred and lacke...

In order to access and resect the acetabular rim, arthroscopic acetabuloplasty was described with labral detachment. When the chondrolabral junction remains intact, acetabuloplasty and labral refixation can be performed maintaining an unharmed labrum. We aimed to evaluate the outcome of a group of patients treated with arthroscopic acetabuloplasty without labral detachment. During the study per...

Motivated by both classroom needs and learning science questions, we developed two computer-based systems to help students learn the English article system (a, an, the, null). The first system, a menu-based task, mimics cloze activities found in many ESL textbooks. The second, a controlled-editing task, gives students practice with both detecting errors and producing the correct response. Resul...
