Brief communication
Developmental and structural affinities between modern human and Neanderthal dental remains continue to be a subject of debate as well as their utility for informing assessments of life history and taxonomy. Excavation of the Middle Paleolithic cave site Lakonis in southern Greece has yielded a lower third molar (LKH 1). Here, we detail the crown development and enamel thickness of the distal cusps of the LKH 1 specimen, which has been classified…

Variation in modern human enamel formation times
Perikymata spacing and distribution on hominid anterior teeth
We documented the spacing and distribution of perikymata on the buccal enamel surface of fossil hominin anterior teeth with reference to a sample of modern human and modern great ape teeth. A sample of 27 anterior teeth attributed to Australopithecus (5 to A. afarensis , 22 to A. africanus ) and of 33 attributed to Paranthropus (6 to P. boisei , and 27 to P. robustus ) were replicated and sputter‐coated with gold to enable reflected light microsc…
Brief communication
One hundred and fifteen unworn anterior teeth were sectioned longitudinally with a diamond saw and prepared for histological examination by polarized light microscopy. Incremental markings in the enamel of each tooth were used to estimate the average total crown formation times of each tooth type. The total time taken to form the crowns of each tooth type was apportioned by 1) cuspal enamel formation and 2) each tenth percentile of total tooth he…
Variations in molar enamel thickness among primates
Because of its hardness, resistance to abrasion and its influence on crown morphology, molar enamel thickness is an important factor in adaptation of the dentition to the diet. Enamel thickness has also been discussed extensively in relation to the phylogenetic relationships among the hominoids. The aims of this study were: (1) to analyse enamel thickness/tooth size relationships among primates as a whole, and (2) to evaluate variations in enamel…
Reducing the prevalence of smoking in youth in Western countries
This paper appraises the major options for the achievement of national targets for the reduction of teenage smoking in Western countries, which has changed little in recent years. The criteria for appraisal include efficacy, cost to the health sector, reach (that is, replica bility), and impact (the combination of reach and efficacy). The major inter ventions appraised include school health education, media and school pro grammes for youth, media…
On thick and thin enamel in hominoids
Martin (1983, 1985) reviewed the significance of enamel thickness in hominoid evolution. He studied cut faces of hominoid teeth using the scanning electron microscope and related enamel prism packing patterns to both enamel formation rates and enamel thickness, although he did not present primary data on formation rates, which he summarised as being either “fast” or “slow.” Martin concluded that thick enamel formed at a fast rate represented the …

Reading Illustrated Science Texts
S ummary . Research has shown that the effect of illustrations on children's learning of science is related to ability. This study examines the hypothesis that children who show different levels of success in a learning task will employ different strategies in their picture‐text processing. One hundred and eighty 14 year‐old children were required to learn three illustrated science topics of different levels of difficulty which were presented to …
Effects of Text Illustration on Children's Learning of a School Science Topic
S ummary . The effect of text and illustration on the learning of a school science topic by 13‐year‐old children was investigated. 272 children studying integrated science in the second year of two comprehensive schools were given texts with varied picture content. Learning was measured by a criterion‐referenced objective items test which differentiated between the effects of pictures on their own, text on its own, the general effect of pictures …
The Effect of Picture Upon the Readability of a School Science Topic
S ummary . The effect of picture upon the readability of a specially written science topic was studied. 338 14‐year‐old children studying CSE Biology in six comprehensive schools completed a cloze test during their study and an objective items recognition test 15 minutes afterwards. Analysis of variance performed on post‐test scores showed that when pictures were present the topic was more easily remembered. However, pictures played little part i…
Use of objective measurement in the validation of self-reported smoking in children aged 10 and 11 years
This study of objective measurement of smoking behaviour reports the findings from a sample of 421 children aged 10 and 11 years from Sheffield. Saliva thiocyanate determination did not provide a satisfactory objective method of validating the self-reported smoking of children in this age group. There was a trend (non-significant) for non-smoking children from homes in which a close relative smoked to have higher concentrations of saliva thiocyan…
