In this article we propose that there are two universal properties for phonological stop assibilations, namely (i) assibilations cannot be triggered by /i/ unless they are also triggered by /j/, and (ii) voiced stops cannot undergo assibilations unless voiceless ones do. The article presents typological evidence from assibilations in over 30 languages supporting both (i) and (ii). It is argued ...

The possibility that a technical error may occur during nerve conduction studies due to ulnar nerve dislocation when the elbow is flexed has recently been suggested. We investigated normal volunteers using ultrasonography to observe the effects of ulnar nerve dislocation during elbow flexion on short-segment nerve conduction studies. We found significant conduction block in all of the subjects ...
