Growth curves were prepared for length of the diaphyses of the six major long bones of the limbs and for length of the calcaneus, talus, cuboid and the first metacarpals and metatarsals, of ages up to 20 years including several immature and many full-term fetuses. Most curves showed what appears to be a consistent adolescent growth spurt at about 17 years, but the number of specimens supporting these parts of the curves is too small for the validity of this spurt to be beyond doubt. The fetal diaphysis lengths were similar to those of Fazekas and Kósa and other recent populations but, compared with curves prepared from the Maresh radiographic data for recent caucasoids, the island diaphyseal growth rate, starting at about 4 months after birth, fell progressively behind so that, by 18 years for example, the femur was 90 mm shorter and the humerus 60 mm shorter than the Maresh equivalents. These findings accord with the short stature of the island adults (male mean 166.2 cm). The growth curves were closer to those of some ancient peoples, Amerindian, caucasoid and negroid, than to contemporary caucasoid. There is evidence of a secular change in growth in this island region because the calculated mean height at 18 years of this earlier island population is at the present time achieved by boys by about 14 years of age. Thus it is argued that the earlier population was affected by stunting factors. Although there is no skeletal evidence of malnutrition, there is plenty of evidence that the way of life was full of hardship in which the children shared. They took a full part in the arduous work involved in farming marginal-quality land; the houses were damp, cold, smoky and dark; they were overcrowded although, mainly because of the high infant-mortality rate, families were not large.  相似文献

This essay takes a new look at the destruction and the rebuilding of the house of commons during the 1940s. It argues that behind the home front bravado of the Palace of Westminster steadfastly enduring the blitz lay secret plans for rehousing MPs away from aerial bombardment, contingency scenarios that were then updated after 1945 in the event of attack on London by atomic weapons. The essay also suggests that threats to the security of parliament, together with the necessity to rebuild the Commons, were turned by the coalition government into an opportunity to refashion parliamentary politics in such a way that the two‐party system was restored, along the traditional lines of government and opposition that had become blurred since 1931.  相似文献

Growth curves were prepared for length and various other dimensions, including some innovative ones, of the scapula, clavicle, first rib, ilium, pubis and ischium of ages up to 20 years including several immature and many full-term fetuses. Most curves showed, like the previously reported diaphyses of the limb bones, what appears to be a consistent adolescent growth spurt at about 17 years, but the number of specimens supporting these parts of the curves is too small for the validity of this growth spurt to be beyond doubt. The fetal dimensions were similar to those of Fazekas and Kósa and of other recent populations. For the post-natal stages of growth, no data are available for comparison but there was close correspondence with the growth curves of some ancient peoples, Amerindian, caucasoid and negroid, whose limb-bone growth rates had also been shown previously to be well below those of contemporary caucasoids. Thus it is argued that the shoulder-girdle and hip-bone data provided further evidence that this Scottish island population was affected by stunting factors. Although there is no skeletal evidence of malnutrition, there is plenty of evidence that the way of life was full of hardship in which the children shared. They took a full part in the arduous work involved in farming marginal-quality land; the houses were damp, cold, smoky and dark; they were overcrowded although, mainly because of the high infantmortality rate, families were not large.  相似文献
