Tooth wear in two ancient populations of the Khazar Kaganat region in the Ukraine

Tooth wear is a common phenomenon in archaeological material. It has been related to the abrasiveness of diet and to the tribological attrition of teeth of individuals. Numerous investigations have been carried out in north and middle American samples as well as African anthropological material. Not much is known about tooth wear in European cultures. Eleven skulls from Chervona Gusarovka, and 14 skulls from the Upper Saltov sites of the Khazar Kaganat region (8th–10th centuries AD) in eastern Ukraine, with different diets were examined. A total of 208 teeth were studied for tooth wear, caries prevalence and periodontal status. Abrasion grades were determined according to a standardised classification and statistically evaluated. Periodontal status was measured using the distance between the enamel‐cementum junction and alveolar crest and the gingival attachment level respectively. Tooth wear was significantly different (P < 0.01) between the two populations. A low caries prevalence of 4.2% in the Chervona Gusarovka population and 1.7% in the Upper Saltov population was found. Significantly more alveolar crest bone resorption on the lingual side was found in the premolars and anterior teeth of the Chervona Gusarovka population. No significant differences were found regarding gingival attachment levels and gingival recession. It is concluded that the content and mode of food preparation influenced tooth wear, as reflected by the prevalence of dental caries and periodontal diseases in these ancient populations.

Analysis of paint residues and paint equipment from North European shipwrecks together with archival research provides evidence of pigments and colours used. The limitations of pictorial sources and contemporary models is contrasted.     

What are patterns in the humanities?

ABSTRACT

This paper is concerned with patterns in past human behaviour, what they are, and how this relates to the detection of patterns in data by means of computation. Theorists have not given patterns the attention they deserve. Therefore it is far from clear what patterns are and to what purpose scholars may use them. This paper presents eight propositions on patterns which hold true for patterns found ‘by hand’ and patterns found ‘by computation’. One such is that a pattern is discernible in behaviour when we subject it to the intentional stance, as the philosopher Daniel Dennett argues. Here behaviour is part of an intentional system. This paper’s argument is that the patterns found ‘by computation’ too are part of an intentional system. To substantiate this claim this paper discusses two important examples of detecting computational patterns in the domain of the humanities.     

Digital geographies of grassroots securitisation

Digital surveillance and securitisation technologies are becoming an increasingly ubiquitous part of everyday lives. Constellations of hand-held devices, smartphone applications and partnerships between police, the security industry and civil society shift responsibility for preventing and recording risk and crimes onto citizens. This development suggests substantial changes to the relationship between state and citizens and is likely to have profound effects on socio-spatial relationships and experiences in place. Until this point, geographers have demonstrated little engagement with these developments. This provocation focuses on particular strengths of theoretical and empirical research traditions in social and cultural geography to suggest ways in which the discipline might constructively engage with the digitisation of citizens’ securitisation practices. It foregrounds four areas in which empirical work on digitally inflected surveillance and securitisation practices will enable a rethinking of key geographical concepts in ways that will further the conceptualisation of digital technology and security. The provocation calls on social and cultural geographers to be mindful of the potential of grassroots securitisation to empower disfranchised communities while considering that these technologies and cognate policies might facilitate the further hollowing out of the state under ongoing processes of neoliberalisation.
