Dating Ancient Burial Mounds in Denmark – Revealing Problematic Ancient Charcoal

The National Museum of Denmark and the Department of Geography at the University of Copenhagen have collaborated on a project investigating burial mounds near early Medieval churches. The aim was to identify a possible continuity in cult sites across the shift to Christianity in the late Viking Age. Charcoal samples from 18 mounds were radiocarbon dated but the results showed they were far older than expected. Control dating undertaken on burial mounds of known age confirmed that charcoal in the mound fill can at least be up to 3000 years older than the mound itself. As charcoal can survive in the surface soil layer for millennia, in spite of ploughing, bioturbation and frost, it may also dominate the charcoal pool of the grass or heather turfs used in the mound construction. Therefore, the article concludes, charcoal cannot be used to securely date archaeological features built with turfs and it is important to be aware of the possible presence of very old charcoal when selecting material for dating archaeological features, even those which otherwise would be judged unaffected by material from earlier archaeological periods.     

Asphaltum hafting and projectile point durability: an experimental comparison of three hafting methods

The design of a projectile delivery system often plays a critical role in the durability and breakage patterns associated with spent projectile points. This paper presents the results of an experimental project designed to examine projectile point durability and breakage patterns between three different hafting methods. Specifically, we compare two asphaltum hafting techniques drawn from archaeological and ethnohistoric accounts from the Central Valley of California with a more stereotypical cross-hatched sinew hafting system. Our results suggest a small yet statistically significant increase in durability among asphaltum hafted points, opening the door to future research on these ethnohistorically documented hafting techniques.     

The Role of Decision Support in the Implementation of “Sustainable Transport” Plans

Improved decision support is deemed essential for the planning and implementation of sustainable transport solutions, but limited evidence exists that decision-relevant information is effectively used for these purposes. This paper applies a framework inspired by research in “knowledge utilization” to examine to what extent various kinds of decision support are used and have become influential in three different planning situations—a local cycle plan in Copenhagen, the Stockholm congestion charging trial and the UK national transport strategy. The results reveal the extensive use of decision support but also the difficulty of unpicking its exact role in each case. Stockholm presented the most successful case, with a mix of academic and experience-based knowledge inputs facilitating understanding and acceptance. The cycle plan example revealed very limited influence of cycling design guidance. The UK national transport strategy fell somewhere in between with evidence of assessment and monitoring of the plans being well bedded in the culture of the organizations involved, but less supportive of sustainability objectives. While decision support and monitoring are clearly relevant, they provide no guarantee for the implementation of sustainable transport solutions.     

After-school Hours and the Meanings of Home: Re-defining Finnish Childhood Space

School children's use of their home during the after-school hours has become a controversial question in Finnish society. The article discusses cultural conceptions and uses of home as a specific space for children by comparing two different sets of empirical data: children's accounts of their after-school spaces and media debate on the same topic. Activated public concern in media accounts is analysed as a process of re-defining the properties of ‘proper places’ for children, whereas children's accounts are interpreted as expressions of local cultures. For the children, home is an ideal place for spending after-school time, while the public debate portrays the home as empty and children as lonely and unsafe. Definitions of home in after-school time are considered as part of a broader cultural process of re-defining contemporary Finnish childhood in which control turns out to be a crucial dimension of children's ‘proper places’.
