Chronic Maxillary Sinusitis in Medieval Sigtuna,Sweden: A Study of Sinus Health and Effects on Bone Preservation

Frequencies of maxillary sinusitis in the population of the medieval town Sigtuna, Sweden, were examined. The first aim was to explore the occurrence of sinus conditions in this urban population, and the second was to investigate the effects of preservation in relation to these changes. The skeletal sample consisted of 274 adolescent and adult individuals buried ca 970–1530 AD. The maxillary sinuses were examined for different types of skeletal change related to sinusitis. The severity and location of these changes were recorded, together with the preservation of the sinus. When the diagnostic criteria for bone preservation from previous studies was used, i.e. the preservation of at least one complete antral floor, the results showed that 97.7% (n = 157) of the individuals were affected, with older individuals showing more severe bone changes. In the entire (i.e. more fragmented) sample, 94.5% (n = 259) showed signs of sinusitis. Again, older individuals showed more severe bone changes, and males were more frequently affected. Also, an increased frequency over time was found. The maxillae were subdivided into groups of bone preservation, and the results showed that there was a significant relation between preservation and the registered presence and severity of sinusitis. The results may be used as a cautionary note against investigating the occurrence of maxillary sinusitis without considering the skeletal preservation factor. There was no correlation between preservation and sex or age groups. This suggests that the differences between younger and older and male and female were not a result of preservation alone and could be considered as trustworthy.

HISTORY OF CHILD WELFARE: A Present Political Concern

ABSTRACT

Since the 1990s, an increasing number of inquiries into the history of children’s out-of-home care have shown that child welfare sometimes failed to protect children. In this Special Issue, we explore how the Nordic countries have responded to allegations and scandals of historical child abuse within child welfare, and also how history matters in these political processes. We ask how Nordic societies have acknowledged past historical child abuse and how they aim to deal with its legacy. Attempts to redress, and provide compensation for, past failures are discussed in the context of transitional justice.     

Stable isotope analysis of a medieval skeletal sample indicative of systemic disease from Sigtuna Sweden

In Sigtuna, Sweden, several medieval cemeteries have been excavated, from which approximately 800 skeletons have been excavated and analysed. Archaeological finds and anthropological analyses have exposed social differences between the cemeteries. Stable isotope analyses have shown that the inhabitants of the town consumed a mixed diet. Significant differences in dietary patterns between the cemeteries may be related to social stratification.In the outskirts of a churchyard excavated in 2006, bone changes showing systemic inflammatory disease indicative of leprosy were observed in six individuals. The burial location suggests that the affected belonged to a lower social stratum. Bone samples were taken from these six individuals, 19 other human skeletons and five animals from the same cemetery for analysis of the stable isotope composition of carbon (C), nitrogen (N) and sulphur (S).The results showed no significant differences in δ¹³C and δ¹⁵N values between the groups, i.e. the seemingly healthy humans and the humans affected by severe inflammatory disease appear to have had similar diets. Nor was a significant difference observed in δ³⁴S data between the six affected individuals and the rest of the sample, implying that no difference in origins could be observed between the two groups studied. However, a comparison between the present study and the previous analysis resulted in significant differences in carbon values.Based on the results obtained in this investigation it is suggested that if a dietary difference existed between people in the outskirts of a cemetery (for example those suffering from leprosy) and people buried in higher ranked regions, it was not a difference in food source but rather in other parameters. Instead dietary differences and possibly social variations are demonstrated between cemeteries. The results from the present study highlight the hierarchical arrangements of social classes in the early medieval society.     

A case study of os cuneiforme mediale bipartum from Sigtuna,Sweden

An adult male from an early Medieval mass grave in Sigtuna displayed bilateral os cuneiforme mediale bipartum. This is an unusual congenital anomaly and this study is the first published example found in an archaeological skeletal assemblage in Sweden. Another adult male in the same grave shows horizontal grooves of both medial cuneiform bones. This paper discusses a possible hereditary tendency of the anomalies.

Embracing the future: path transformation and system reconfiguration for self-driving cars in West Sweden

ABSTRACT

The past years have witnessed a surge of academic interest into how new industrial paths are developed in regions. Transformation processes of existing regional industries have received less attention. This article focuses on radical innovation-based renewal processes of established paths and investigates how regional innovation systems are tackling challenges related to path transformation. Drawing on insights from the regional and technological innovation systems literatures, we develop an analytical framework that elucidates the relation between path transformation and system reconfiguration. The framework suggests that regional innovation system elements are created or adapted to (i) target the build-up of system functions regionally; (ii) link up to system functions in other locations, and (iii) transplant system functions from elsewhere. The analytical framework is applied to a case study of the transformation of the automotive industry in West Sweden towards self-driving cars. The empirical analysis provides support for the importance of the three types of system reconfiguration and emphasises the relevance of different types of assets. Furthermore, it highlights how actors tend to utilise previous networks and positions in global innovation systems rather than turning to the development of system functions regionally as the ‘default option’ of system reconfiguration.     

Young people’s everyday landscapes of security and insecurity

Abstract

Debates about ‘security’ rarely feature children or younger people, whilst research with children and young people seldom focuses upon issues traditionally found within security studies. Building upon long-standing debates about political geographies of youth and political participation as well as feminist geopolitics and emerging discussions about children’s and young people’s geopolitics, we chart young people’s everyday landscapes of security and insecurity. Key themes explored here include: secure pasts and insecure futures; ontological security and insecure selves; online security and digital insecurities; home(land) securities and insecure households and families; and global securities and insecure worlds.
