Production and use of birch bark tar at the Neolithic pile-dwelling of Palù di Livenza (North-Eastern Italy) revealed by X-ray computed micro-tomography and synchrotron Fourier-transform infrared spectroscopy

Recent excavations at Palù di Livenza (northeastern Italy) revealed a multiphase Neolithic pile dwelling dated between ca. 4,300/4200 and 3,600 cal BC. Three lumps with teeth imprints and a larger amorphous piece from the Late Neolithic layers have been studied by X-ray computed micro-tomography (microCT) and synchrotron Fourier-transform infrared spectroscopy (FTIR). FTIR spectra match well that of birch bark tar and microCT of the larger piece has revealed a rolled-up structure likely corresponding to bark rolls. The lumps of birch pitch were probably chewed to soften the tar prior to be used as hafting adhesive or therapeutic substance. The rolled-up inner structure of the larger piece and the remains of birch bark tar and abundant charcoals on its surface suggest it probably corresponds to a rare waste product from allothermic tar production.     

Was Photios an Anti‐Latin?: Heresy and Liturgical Variation in the Encyclical to the Eastern Patriarchs

In discussing Epistle 2, most of the attention has been focused on the discussion of the filioque, to the exclusion of Photios’ other liturgical and ecclesiastical comments. While the filioque arguments are now widely seen as an interpolation into the text (though whether by the hand of Photios or another author can be debated), these additional comments are largely glossed over. However, the liturgical comments in Photios’ Ep. 2 are indeed a central point of contention for the Patriarch himself, rather than a scribe or secondary author. Photios’ antagonism towards Latin liturgy is part of a broader cultural conflict between the two halves of medieval Christendom. For Photios, as well as his predecessors and successors, Orthodoxy was increasingly defined as not only a theological issue, but an issue of praxis, and the presence of innovative liturgical practices was indicative of a perverted theology. These sorts of differences would have been especially notable for Greek missionaries to the Bulgars who lived and worked beside, and in opposition to, Latin missionaries in a competition for ecclesiastical hegemony. Ultimately, Photios’ writings against the liturgical practices of the Latins were of considerably greater importance to his contemporaries than the filioque was to his successors, and the implications of Photios’ theology, given his enduring importance to Orthodox Christianity, have the potential to create new flashpoints in contemporary discussions between Orthodox and Western Christians.     

Unwritten Factors Affecting Structural Funds: The Influence of Regional Political Behaviours on the Implementation of EU Cohesion Policy

While EU regional policy has the ambitious objective of supporting lagging regions and promoting inter-regional convergence, its impact is dependent on the ability of regional policymakers to secure and use EU funding to meet the region's needs. This paper aims to show under which conditions politics has a defining influence on the distribution, allocation and utilization of structural funds (SF), specifically in Objective 1 regions. The empirical analysis focuses on the 2000–2006 programming cycle in France, Germany, Italy, Spain and the UK. The results show that regions politically aligned with national governing coalitions tend to perform better in terms of received SF support and enjoy more flexibility in implementing SF. However, the influence of regional political behaviours on economic performances is very limited. The findings confirm the importance of politics in influencing SF implementation, but its limited influence on economic outcomes.     

The Eslington Sword and the Kingdom of Northumbria

NEW DISCOVERIES may indicate the location of a previously unknown early medieval burial ground in central Northumberland. Objects discovered during the course of metal-detecting include an assemblage with a folded, pattern-welded sword and zoomorphic shield mount. Excavation indicated near total destruction of deposits as a result of post-medieval land-use and only Bronze-Age burials inserted into bedrock remained intact. Three putative early medieval burials are identified here, with the largest assemblage associated with a high-status male. The sword and shield mount from this assemblage are comparable with finds from high-status burials in southern and eastern England. Together with the landscape context of the site, the assemblage provides evidence for the burial practices of an emerging Northumbrian elite in the late 6th century ad.     

The Impact and Legacy of the Otterburn Public Inquiry,Northumberland National Park,England

The Otterburn Public Inquiry (1997 and 1999) polarized opinion as to how England’s finest countryside should best be utilized. On the one hand, the Ministry of Defence sought to realize a major development in a protected area, whereas on the other, Northumberland County Council and Northumberland National Park Authority opposed the plans, arguing that conservation and recreation should take priority. This study was undertaken several years later and took a retrospective look at the saga through a recollection of personal accounts, so as to examine the impact and legacy that was borne out of this development. Semi-structured interviews were undertaken with a number of stakeholders as part of a wider project on partnership working. It was found that the Ministry of Defence used this planning dispute to affirm that defence of the realm was a greater national interest than environmental protection. The outcome of the Public Inquiry was also found to contribute towards a radical change in the way Northumberland National Park was managed.     

Insights into the processes behind the contamination of degraded human teeth and bone samples with exogenous sources of DNA

A principal problem facing human DNA studies that use old and degraded remains is contamination from other sources of human DNA. In this study we have attempted to contaminate deliberately bones and teeth sampled from a medieval collection excavated in Trondheim, Norway, in order to investigate this poorly understood phenomenon. Five pairs of teeth and bone samples were bathed in water containing various concentrations (from 10⁻⁹ and 10⁻²¹ g/l) of purified ΦX174 DNA. Subsequently the samples were subjected to a routine decontamination protocol involving a bleach bath followed by exposure to λ=254 nm ultraviolet light, prior to DNA extraction and analysis for evidence of the persistence of the contaminant. The results support previous speculation that bone is more susceptible to water‐borne sources of contaminant DNA, although both bone and teeth are readily contaminated and are difficult to decontaminate using the tested protocol. We believe that this is largely due to the porous nature of bone and teeth facilitating the deep penetration of the contaminant DNA. To simulate a more realistic handling situation, 27 further teeth were directly handled and washed, then decontaminated, prior to assaying for the residual presence of the handler's DNA. Surprisingly, although our results suggest that a large proportion of the teeth were contaminated with multiple sources of human DNA prior to our investigation, we were unable to contaminate the samples with further human DNA. One potential explanation may be the deposition of sediment or other structural changes that occur within the samples as they desiccate post‐excavation, which may protect samples from subsequent contamination, but also prevent the efficacy of bleach baths in decontaminating specimens.
