dc.description.abstractIn the scoliotic spine, torsion is generally evaluated in relation to axial rotation of the apical vertebra. In the lower limbs, the changes in torsion by age of femoral anteversion (FAV) relative to tibial torsion (TT) have been studied in dried bones, normal growing subjects and adults and subjects with osteoarthritis of the hip or the knee. This paper reports the application of real-time ultrasound to FAV and TT in normal children age 11-18 years and in scoliosis screening referrals with particular reference to how FAV relates to TT as 1) ratios, and 2) tibio-femoral index (TFI) of torsion, calculated as TT minus femoral FAV. The FAV/TT ratio findings show an abnormal normal relationship of FAV to TT both proximo-distally and in left-right asymmetry. These may express torsional abnormalities in femoral and/or tibial growth plates with left-right asynchrony suggesting the possibility of similar torsional abnormalities in vertebral end-plates and/or rib growth plates initiating the deformity of AIS. TFI of the right limb in the scoliosis girls is greater than in the normals that is interpreted as resulting from earlier skeletal maturation of FAV. FAV/TT ratios and TFI are unrelated to the spinal deformity (Cobb angle and apical vertebral rotation) except for boys where TFI is associated with apical vertebral rotation. FAV/TT ratios may be a more accurate method estimating the relationship of FAV to TT. than TFIs.
dc.description.abstractThe English stop voicing contrast is examined in both word-initial position (via VOT) and word-final position (via the duration of the preceding vowel) in young adult speakers born and brought up in the Shetland Isles. The subjects'parents were either also from Shetland, from elsewhere in Scotland, orEngland. All have identical phonemic stop systems, unambiguously so ininitial position. The quasi-phonemic role in Scottish English of vowelduration in signalling the suffixual vs. tautomorphemic word final /d/ insteadof the /t/-/d/ contrast (the Scottish Vowel Length Rule) renders final positionmore complex. There are fine-grained interspeaker differences covering awide area of the phonetic space, exemplifying the potential forphonologically-relevant variation. The targets may be speaker-specificresponses to input, especially mismatches between the dialect of their parentsand the wider community.
