Changes in starch grain morphologies from cooking

One of the three main plant microfossils, starch grains are increasingly used as markers of diet, plant domestication, tool use and site organization, because their morphology and features provide a means to identify the plant that produced them. However, starch grains are susceptible to damage when they are exposed to heat in the presence of water, as in cooking. We documented the changes that occur in the starch grains of 10 domesticated plant species due to exposure to different cooking methods, in order to better understand how cooking alters the appearance of the grains, and if these cooking methods might be identifiable in the archaeological record. Our results show that some cooking methods produce unique, identifiable damage on some types of plant starches, but generally each plant species reacts uniquely to cooking. In order to record the changes for each plant species, we have created a database, available at (http://www.osresearch.net/∼hollyf/starchdb/index.cgi), to which registered users can add their own images of cooked starch grains.     

Cleft palate: a case study of disability and survival in prehistoric North America

This study presents an analysis of an adult male that demonstrates diagnostic markers of cleft palate. The burial is associated with the Grider Site, Late Woodland context (AD 500 to 1000), located in Pike County, Indiana, USA. The analysis draws on clinical and palaeopathology literature to consider other possible conditions responsible for the skeletal anomalies. Cleft palate occurs in about one in 1000 live births, and is one of the most common defects of the face. Despite the high frequency of cleft palate, few cases are reported from the archaeological record. It is possible that, in the past, few infants survived extreme forms of cleft palate, and such cases are not present to be recorded. Or, it is possible that the lesion simply goes undocumented. This analysis outlines the markers of cleft palate in this individual and demonstrates that a prehistoric culture could overcome the health issues experienced by an infant with the condition (full communication between the oral and nasal cavities) and survive to adulthood.

Yorkshire’s influence on the understanding and treatment of mental diseases in Victorian Britain: The golden triad of York,Wakefield, and Leeds

In the late-eighteenth and nineteenth centuries, a more humane approach to the care of the insane in Britain was catalyzed in part by the illness of King George III. The Reform Movement envisaged “moral” treatment in asylums in pleasant rural environments, but these aspirations were overwhelmed by industrialization, urbanization, and the scale of the need, such that most asylums became gigantic institutions for chronic insanity. Three institutions in Yorkshire remained beacons of enlightenment in the general gloom of Victorian alienism: the Retreat in York founded and developed by the Quaker Tuke family; the West Riding Lunatic Asylum in Wakefield led by Sir James Crichton-Browne, which initiated research into brain and mental diseases; and the Leeds Medical School and Wakefield axis associated with Sir Thomas Clifford Allbutt, which pioneered teaching of mental diseases and, later, the first Chair of Psychiatry. Three other Yorkshiremen who greatly influenced nineteenth-century “neuropsychiatry” in Britain and abroad were Thomas Laycock in York and Edinburgh, and Henry Maudsley and John Hughlings Jackson in London.     

Keeping cool: practicing domestic refrigeration and environmental responsibility

Domestic refrigerators have become symbols of climate change in energy efficiency campaigns; they are equipment that both permits and prohibits the performance of environmental citizenship. However, little is known about how subjectivities and practices interact, particularly with regard to questions about refrigeration and domestic energy. What might those of us interested in household sustainability learn from the relationships among refrigerators, energy, subjectivities, and practices, and from what these may reveal about environmental responsibility? We draw on data from mixed‐method qualitative research conducted with 28 households in Wollongong, Australia, and frame the analysis in terms of social practice theory, with additional attention to subjectivity. This framing helps us develop thinking about how refrigeration is done and consider whether and how things become waste by paying closer attention to the spatial imperatives underpinning these practices. It also assists us in considering how the ongoing relationships of social and material aspects of refrigeration co‐constitute a range of subjectivities. Further, our analysis advances discussions on how household practices and identities relate to public campaigns about environmental responsibility, particularly as the latter is constructed in terms of ‘energy efficiency’.
