The preservation of lead within human tissue makes it possible to monitor long-term exposure to the element and to model changing sources of lead pollution throughout the lifetime of an individual. Dental tissues have recently been shown to be particularly useful for this purpose. Enamel, for instance, forms at known stages of life and is chemically stable(More)
Two single-subject experiments with two adult stutterers were conducted to assess the effect of changing the frequency of phonation intervals that were shorter or greater than prescribed durations during spontaneous speech. Both subjects modified the frequency of prescribed phonation intervals and showed changes in the frequency of these intervals that were(More)
There is a considerable body of evidence to support the contention that the atmospheric Pb burden is now considerably greater than it was in the remote past. However, as there are a diversity of potential environmental pathways leading to Pb ingestion, it is not clear how atmospheric Pb levels relate to human exposure. It is necessary to establish a(More)
The purported migrations that have formed the peoples of Britain have been the focus of generations of scholarly controversy. However, this has not benefited from direct analyses of ancient genomes. Here we report nine ancient genomes (∼ 1 ×) of individuals from northern Britain: seven from a Roman era York cemetery, bookended by earlier Iron-Age and later(More)
OBJECTIVE To assess the effects of a 3-year programme aimed at controlling scabies on five small lagoon islands in the Solomon Islands by monitoring scabies, skin sores, streptococcal skin contamination, serology and haematuria in the island children. METHODS Control was achieved by treating almost all residents of each island once or twice within 2 weeks(More)
Acute respiratory infections in children aged less than 5 years in the Eastern Highlands of Papua New Guinea were investigated bacteriologically for 10 years from November 1978. Haemophilus influenzae and Streptococcus pneumoniae were responsible for 73% of all bacteria cultured from lung aspirate (83 samples), 85.5% from blood (1024 samples) and 92% from(More)
61 have advanced the idea that people might slip into trance spontaneously, so that responses to suggestion can be taken as evidence that the person is in a hypnotic state. The circularity of this position has long been argued. People are hypothesized to be responding to suggestion because they have slipped into a trance, but the only reason for claiming(More)
RATIONALE The 19th century excavation of an exceptionally well-preserved Early Bronze Age high status log-coffin burial from northern England, dated to 2200-2020 BC, yielded a 'food residue' collected from the inside of an accompanying bark vessel. This residue contained fibrous stitching that was used to hold the bark walls of the vessel together, first(More)
The hunter-gatherer transhumance model presents foragers as specialised hunters of migratory ungulates, which moved seasonally between coastal lowlands and interior uplands. We studied six animal teeth of horse (Equus hydruntinus) and red deer (Cervus elaphus) from four different archaeological sites: the Grotta di Vado all'Arancio, Grotta di Settecannelle,(More)
OBJECTIVES To determine the prevalence of β-lactamase-negative ampicillin-resistant (BLNAR) Haemophilus influenzae in Australia and characterize the associated amino acid substitutions in penicillin-binding protein 3. METHODS Two hundred consecutive non-repeat clinical isolates of H. influenzae were collected and β-lactamase-negative isolates were(More)
