History and Policy Studies

This article deals with actual and potential contributions of history to policy studies. Some historians have attempted to influence specific policies through their writings, others have held policy-relevant positions in government agencies, while others have functioned in roles that have made them official preservers of our past. The authors discuss a number of ways in which history is relevant to policy studies-among them, the conception of history as a policy laboratory, as a source for perspective about the development of current policies, as a source of theoretically interesting rare or unique occurrences, and as a repository of values to which appeals can be made to justify current and proposed policies. Historians are becoming aware of the need for alternative careers to teaching in universities and this has led them to seek an increase in the number of policy-relevant positions for historians in government.     

Rates of dentine mineralization in permanent human teeth

Previous experimental studies have estimated linear rates of dentine formation in modern humans to be close to 4μm day⁻¹. In this study a method similar to that first adopted by Kawasaki, Tanaka and Ishikawa⁵ was used to estimate linear rates of dentine mineralization over a period of 1200 days in both the cusps and cervical regions of several permanent tooth types. All teeth were from the same individual. Rates in the cusps of teeth with the tallest crowns were estimated to be between 5 μm day⁻¹ and 6 μm day⁻¹. This is higher than previous estimates in permanent tooth crowns, although rates in the cusp of a first permanent molar, where cusps were less tall and cuspal dentine therefore less thick, were close to previous estimates of 4 μm day⁻¹. Despite this variation in cuspal rates, mineralization rates were linear in all cusps studied over a long period of time. Rates in the cervical region, either close to the enamel dentine junction or to the cement dentine junction, were estimated to be between 1.3 μm day⁻¹ and 1.5 μm day¹¹, much slower than reported previously. Rates in the mid-portion of the dentine, in both the lateral part of the crown and in the cervical one-third of the root, rose steadily to match rates in the cuspal region, but then slowed towards the pulp chamber. These data extend the findings of previous studies on permanent human dentine. They demonstrate a wide range of mineralization rates in permanent dentine and provide a more secure basis for judging different rates in different locations of different human tooth types.

Reflections on Le Quebec d'en Haut et le Quebec d'en bas

At the beginning of the 20th century Quebec stretched beyond its current boundaries. Indeed, it was commonplace to speak of Quebec d'en haut (upper) and Quebec d'en bas (lower). A common destiny seemed to disintegrate a third of the way through the century only to be rekindled in recent times.     

A new protocol for radiocarbon dating of hair and keratin type samples—application to an Andean mummy from the National Museum of Natural History in Paris

The protocol of preparation of keratinized samples (e.g. hair, furs …) for radiocarbon dating that we have developed is based on the selective extraction of keratin from the bulk part of the shaft (cortex). The aim of this method is to eliminate the cuticle which could contain exogenous carbon from external contaminations. The total treatment takes place as follows: a washing/dry cleaning, a soft treatment with diluted acidic and basic solutions (acid/alkali/acid method) similar to the protocol used for vegetal samples, extraction of keratin by reduction using dithiothreitol and precipitation with sodium deoxycholate and trichloroacetic acid. This method was applied on a hair sample from an Andean mummy, conserved in the collections of the Anthropology Laboratory of the National Museum of Natural History (Musée de l’Homme) in Paris, France. The results of two runs reveal that the mummy is dated to a period between the eleventh century and the first half of the twelfth century. It therefore belongs to the Late Intermediate period (900–1450?ad). The combination of historical research, the study of the body by computed tomography and the analysis of mineral deposits on the surface of the body provides clues to identify the geographical origin of the mummy. These investigations led to determine that the mummy comes from the region of Tarapacá in Chile and belongs to the cultural complex Pica-Tarapacá.     

‘Angelic Spirits of ‘68’: Memories of 60s’ Radicalism in Responses to the 2010–11 UK Student Protests

The winter of 2010–11 saw a significant upsurge of student protest in Britain. This paper analyses the numerous references to 60s’ radicalism which circulated in responses to the protests, with a focus on left-wing media. Drawing on performativity theory, the paper traces the highly polarised divisions between affirmations and repudiations of ‘1968’ in responses to the protests. This polarisation, I argue, reflects an absence of a clear-cut collective memory of the British radical 60s. More broadly, the paper sheds light on the hitherto under-explored mechanisms through which memories of ‘1968’ shape the discursive and affective landscape of contemporary radical politics.     

Tapa Cloths and Beaters: Tradition,Innovation and the Agency of the Bounty Women in Shaping a New Culture on Pitcairn Island from 1790 to 1850

This article examines the tapa cloths made by the women associated with the Bounty, who sailed to Pitcairn Island with the Bounty mutineers to create a new society and culture. Traditional literature reveals a male-dominated narrative, which ignores any female agency in the Bounty-Pitcairn story, and merely objectifies them. The tapa cloths the women produced reveal much about their origins and their efforts to maintain the traditions of their homelands while initiating innovative designs that appear to have provided a sense of unique identity in the Anglo-Polynesian children of the Polynesian women and their European husbands. Given their objectification in the generally accepted historical narrative, it is ironic that the women reveal themselves through the objects that they made. By compiling data about the tapa cloths (kind of cloth, plants used, techniques, colour and patterning, quality), details of tradition and innovation emerge and reveal much about these women and the knowledge they passed down the generations through their daughters.
