This paper presents the results of a study of the expression of word-level prosody in Jordanian Arabic. The study focuses on the durational, spectral, and fundamental frequency correlates of stress and word-"nal juncture in the speech of four speakers. Speakers exhibit extensive "nal lengthening e!ects and a smaller e!ect of stress and penultimate lengthening. Stress lengthening correlates with...

Adaptations to repeated bouts of injury-inducing lengthening contractions were studied in mouse anterior crural muscles. Five bouts of 150 lengthening contractions were performed in vivo, with each bout separated by 2 wk of rest. Three primary observations were made. First, there was little, if any, attenuation in the immediate isometric torque losses after lengthening contractions at "physiolo...

Children's early word productions often differ from the target form, sometimes exhibiting vowel lengthening when word-final coda consonants are omitted (e.g., dog /dog/ --> [d(c):]). It has typically been assumed that such minimal words lengthening compensates for a missing prosodic unit (a mora). However, this study raises the alternative hypothesis that vowel lengthening in early productions ...

We tested the hypotheses that lengthening contractions, isometric contractions, and passive stretches increase muscle inflammatory cells (neutrophils and macrophages) and that prior conditioning with lengthening contractions, isometric contractions, or passive stretches reduces neutrophils and macrophages after subsequent lengthening contractions. Extensor digitorum longus muscles in anesthetiz...

This study investigated the influence of the torque produced by plantar flexor muscles on cortical and spinal excitability during lengthening and shortening voluntary contractions. To that purpose, modulations of motor-evoked potential (MEP) and Hoffmann (H) reflex were compared in the soleus (SOL) and medial gastrocnemius (MG) during anisometric submaximal and maximal voluntary contraction (MV...

Prosody facilitates perceptual segmentation of the speech stream into a sequence of words and phrases. With regard to speech timing, vowel lengthening is well established as a cue to an upcoming boundary, but listeners' exploitation of consonant lengthening for segmentation has not been systematically tested in the absence of other boundary cues. In a series of artificial language learning expe...

Femoral lengthening using the Intramedullary Skeletal Kinetic Distractor is a new technique. However, with intramedullary distraction the surgeon has less control over the lengthening process. Therefore, 33 femora lengthened with this device were assessed to evaluate the effect of operative variables under the surgeon's control on the course of lengthening. The desired lengthening was achieved ...
