Consilience of genetics and archaeobotany in the entangled history of rice

Major leaps forward in understanding rice both in genetics and archaeology have taken place in the past decade or so—with the publication of full draft genomes for indica and japonica rice, on the one hand, and with the spread of systematic flotation and increased recovery of archaeological spikelet bases and other rice remains on early sites in China, India and Southeast Asia. This paper will sketch a framework that coherently integrates the evidence from these burgeoning fields. This framework implies a reticulate framework in the phylogeny of early cultivated rice, with multiple starts of cultivation (two is perhaps not enough) but with the key consolidations of adaptations that must have been spread through hybridisation and therefore long-distance cultural contacts. Archaeobotanical evidence allows us to document the gradual evolutionary process of domestication through rice spikelet bases and grain size change. Separate trends in grain size change can be identified in India and China. The earliest centre of rice domestication was in the Yangtze basin of China, but a largely separate trajectory into rice cultivation can be traced in the Ganges plains of India. Intriguingly, contact-induced hybridisation is indicated for the early development of indica in northern India, ca. 2000 BC. An updated synthesis of the interwoven patterns of the spread of various rice varieties throughout Asia and to Madagascar can be suggested in which rice reached most of its historical range of important cultivation by the Iron Age.     

“Committed as Near Neighbors”: The Halifax Explosion and Border-Crossing People and Ideas

Popular accounts of the Halifax Explosion of 1917 have placed it in a resolutely nationalist context. But starting from the international ownerships and destinations of the ships that sparked it, the explosion was a transnational event. This article explores how people, money, and ideas crossed and recrossed the border. First, in-kind and monetary relief flowed quickly from the United States, Britain, and Newfoundland. Second, Halifax became a destination for a growing international community of experts in disaster response, as relief experts from New York, Boston, Winnipeg, and elsewhere in North America converged on the city. Finally, survivors used their transnational community of friends and relatives to build political power over the relief process. Migrants living in “the Boston States” created a transnational polity that pressured relief authorities to give more money to their kin still in Halifax. These transnational communities—of international experts and migrant families—helped create a Canada–US relationship from the bottom.     

Dendrochronology reveals the construction history of an early 19th century farm settlement,southwestern Virginia,USA

The McDonald Farm (also called the Anderson-Doosing Farm) in Catawba Valley, Virginia dates to 1789 and is registered with the National Register of Historic Places maintained by the National Park Service. According to written accounts, oral histories, and architectural analyses, the construction of four structures (a collapsed cabin, a standing cabin, a barn, and a smokehouse) at the farm likely occurred in the early to mid-19th century. To verify and refine the construction dates of the four structures, we absolutely dated the tree rings in logs used in their construction by comparing their ring patterns with a composite reference tree-ring chronology created from four regional locations. We used established graphical and statistical techniques used in dendrochronology to ensure that all tree rings were dated absolutely with 99.99% certainty. We found cutting dates for the collapsed cabin ranged from 1809 to 1810, making the likely builder Samuel Myers and not Joseph Anderson, who is currently given credit for its construction. The logs in the barn had cutting dates ranging from 1830 to 1831, confirming the 1830 construction date estimated by the historical documents and confirming the builder was Joseph Anderson. The logs from the standing cabin and smokehouse had cutting dates ranging from 1838 to 1840, refining the “mid-19th century construction” listed in the register nomination. Furthermore, the nomination gave credit of the construction of these latter two structures also to Joseph Anderson, but the builder was actually John Gish who owned the farm from 1837 to 1845. Our study demonstrates the benefit and reliability of using dendrochronology to verify and refine construction dates and ownership histories of historic structures in the Southeastern U.S.     

Watery masculinities: fly-fishing and the angling male in the South West of England

This article examines the masculinities evident through fly fishing for salmon and trout in the South West of England. It identifies the way that many accounts of rural masculinities focus on particularly macho traits such as strength, resilience and domination and particular relationships with nature and the environment. Such macho traits are evident in the masculinities of angling – the angler regularly discusses issues of competition and duelling with nature. The trophies of such encounters become significant as they are used to summon life to stories and become crucial in narrating masculinity. However alongside these macho traits are numerous additional masculinities which are in tension with the more macho elements. These ‘additional masculinities’ become evident in the watery landscapes of angling; as such these waterscapes can be considered as liminal spaces as they enable masculinities to slip and reform. Therefore what emerges is a cadence to masculinity with different subject positions becoming significant in different spaces.     

Millet cultivation history in the French Alps as evidenced by a sedimentary molecule

We report on the detection, in a sediment core drilled in Lake Le Bourget (French Alps), of a fossil molecule (miliacin) that was synthesized by broomcorn millet cultivated in the watershed, and then exported to the sediment. The variation in abundance of this molecule allows us reconstructing the history of millet cultivation around Lake Le Bourget. Our results support the introduction of millet around −1700 BC in the region. After an intensive cultivation during the Late Bronze Age, the failure of millet cropping during the Hallstatt period coincides with a phase of climatic deterioration. Millet cultivation recovers during the Roman and Mediaeval periods before falling most probably due to the introduction of more productive cereals. These pioneering results constitute the first continuous record of an agrarian activity covering the last 6000 years and emphasize the close relationships between local hydrology, land use and agro-pastoral activities around Lake Le Bourget.     

School holidays: examining childhood,gender norms,and kinship in children's shorter-term residential mobility in urban Zambia

This article discusses a practice of child residential mobility in Zambia that is frequently overlooked in migration studies and difficult to capture through standard survey methods: the practice of ‘going on holiday’ to the homes of relatives during breaks in the school term. Drawing on child-centered and quantitative research, this article examines the multiple dimensions of ‘going on holiday’ for children living in a low-income urban settlement in Lusaka. Findings suggest that the practice was gendered and may map onto changing norms in schooling in Zambia. Within a context where resources are severely constrained, going on holiday may serve as one means for cultivating reciprocity, sharing the burden of care and household labor, and strengthening kin ties. This work further demonstrates the importance of using locally meaningful terms and practices in survey research where general questions about children's mobility may fail to capture the nature and extent of children's movements.
