Fingerprint evidence for the division of labour and learning pottery-making at Early Bronze Age Tell es-Sâfi/Gath, Israel.

The organization of craft production has long been a marker for broader social, economic and political changes that accompanied urbanism. The identity of producers who comprised production groups, communities, or workshops is out of reach using conventional archaeological data. There has been some success using epidermal prints on artefacts to identify the age and sex of producers. However, forensic research indicates that a combination of ridge breadth and ridge density would best identify the age and sex of individuals. To this end, we combine mean ridge breadth (MRB) and mean ridge density (MRD) to distinguish the age and sex of 112 fingerprints on Early Bronze Age (EB) III pottery from the early urban neighbourhood at Tell es-Sâfi/Gath, Israel, dating to a 100 year time span. Our analysis accounts for the shrinkage of calcareous fabrics used to make six type of vessels, applies a modified version of the Kamp et al. regression equation to the MRB for each individual print, and infers sex by correlating MRD data to appropriate modern reference populations. When the results are combined, our analyses indicate that most fingerprints were made by adult and young males and the remainder by adult and young females. Children's prints are in evidence but only occur on handles. Multiple prints of different age and sex on the same vessels suggest they were impressed during the training of young potters. Production appears dominated by adult and young males working alone, together, and in cooperation with adult and/or young females. Vessels with prints exclusively by females of any age are rare. This male dominant cooperative labour pattern contrasts recent studies showing that adult women primarily made Neolithic figurines in Anatolia, and more females than males were making pottery prior to the rise of city-states in northern Mesopotamia.

Diagnosis and Control of a LPAI H5N8 Outbreak in a Japanese Quail (Coturnix coturnix japonica) Commercial Flock in the Central Valley of California.

In April 2014 an outbreak of low pathogenic avian influenza H5N8 North American genetic lineage was diagnosed in a commercial quail operation in Stanislaus County, California. Sudden increase in mortality prompted the submission of 20 Japanese quail hens (Coturnix c. japonica) to the California Animal Health and Food Safety Laboratory, Turlock Branch. Oropharyngeal and cloacal swabs tested positive for influenza A virus H5N8 by real-time reverse transcription-polymerase chain reaction. The virus was subsequently isolated. In vivo assay and sequencing of the hemagglutinin protein cleavage site classified the virus as a North American genetic lineage of low pathogenicity for chickens. Following the diagnosis, a rapid and coordinated response took place to contain the outbreak. The affected premise was depopulated, cleaned, and disinfected. Three areas from the affected premises-a 3 kilometer (km) radius (High Risk Zone), a 3-10 km area (Buffer Zone), and a 10-20 km (Surveillance Zone)-were established for avian influenza testing of commercial and noncommercial poultry operations. Surveillance testing and rapid control measures were successful in the control and eradication of the outbreak and revealed no area of spread of the virus from the index flock. This report describes the history, diagnosis, surveillance, and control measures applied to manage this outbreak.
