Hydrogen isotope systematics of hair: archeological and forensic applications

The hydrogen isotope systematics of hair have been explored and several applications demonstrate the type of information that can be recovered from archeological and forensic hair samples. Experiment with modern hair demonstrate that sources of protein-based hydrogen in keratin are food and water. On the basis of a deuterium-enriched drinking study, it was found that 31% of hydrogen in human hair is derived from ingested water. At least 9% of total hydrogen in human hair is isotopically exchangeable with water or water vapor at 25 °C. Nearly complete exchange occurs in a matter of hours. The δD value of body water is approximately 17±10‰ (n=7) more negative than human hair, although there is much scatter in data for modern hair, which is clearly related to variability of the isotopic composition of ingested food and water. Archeological hair samples were analyzed from (i) a 370 year old Incan mummy sacrificed at 5300 m altitude in Argentina (Geoarchaeology 14 (1999) 27) and (ii) from a Woolly Mammoth from Siberia. High spatial resolution data along the length of hair from the mummy indicate seasonal variations in carbon, nitrogen and hydrogen isotope ratios. No hydrogen isotope anomalies are seen in the youngest hair at the base of the scalp, indicating that the individual probably lived at 1600 m, and spent less than a week at high altitudes before death. The mammoth also preserves a seasonal signal, suggesting hair growth rates of 33 cm/year, faster than human hair, but slower than horse tail hair. The limited isotopic range across seasons for the mammoth is consistent with a north-south migration on the order of 1000 km.     

Manipulating the Maritime Cultural Landscape: Vernacular Boats and Economic Relations on Nineteenth-Century Achill Island,Ireland

Resistance to British control of Ireland’s maritime landscape under the United Kingdom of Great Britain and Ireland (1800–1922) was highly localized, enacted in part through Irish choices in boat construction and patterns of movement at sea. British naval authorities overseeing Achill Island in County Mayo used both coercive and conciliatory means to replace Irish subsistence fishing from regional vernacular boats with commercial fishing from larger non-local vessels reliant upon piers and dredged harbors. These changes encouraged islanders’ dependency upon imported food and wage-based employment performed under Protestant surveillance. Indigenous boats including curraghs and yawls played central roles in Irish resistance to these changes, through the assertion of traditional lifeways and practices.     

The Achill Yawl: vernacular boats in historical context on Achill Island,Ireland

Achill yawls, originally introduced to Ireland as ships' boats aboard Norwegian merchantmen, developed into distinct working vessels along Achill Island's shores during the 19th century. These boats were subsequently modified for recreational racing in the mid‐20th century. Despite changes to their design, they are often nostalgically viewed as traditional symbols of an Achill islander identity, though their popularity may have been prompted by late‐19th‐century British legislation. The authors take an ethnographic approach in interpreting Achill yawls over time, contextualizing their social functions through an exploration of primary historical and photographic archives, extant vessels, and interviews with Achill islanders. © 2010 The Authors     

Writing the Taiping War into the History of the Southern Ming: Xu Zi,the Militia of Luhe,and the Annals of a Fallen State

Between 1853 and 1858, the militia and hired braves of Luhe county, Jiangsu, distinguished themselves by successfully defending against Taiping attack when surrounding counties and cities all fell. The historian Xu Zi (1810–62) served as a militia leader, commanding a company of troops and working to raise funds to pay for provisions. At the same time, he was writing his history of the Southern Ming Courts: Annals of a Fallen State, With Appended Annotations (Xiaotian jinian fukao). In his history, Xu Zi included anecdotes of his wartime experiences, writing the Taiping War into the history of the Southern Ming. What does history do? Xu Zi hoped it could help establish and maintain the coherence of the forces fighting the Taiping. To that end, he presented exemplary figures from the past for people of his own time to emulate, and he narrated those stories to his fellow soldiers. At the same time, his work suggests that the practices of the historian—including investigation of sources, expressions of emotion, and evaluation of policy—could provide avenues for defeating the Taiping. By writing himself into his history of the Southern Ming, he showed how the past could become a tool of war.
