Cross-Border Networks in Informal and Formal Cooperation in the Border Regions Andalusia–Algarve–Alentejo and South Finland–Estonia

Fostering border relations among the people in border regions seems a precondition for the future envisagement and success of cross-border regions and European Integration. Related studies to border relations observe the weakness of these informal border contacts and relations. However, weak ties represent an opportunity for interaction, and little has been said about how they might play in the construction and performance of institutional cross-border cooperation (CBC). In this work, we examine the nature of personal border networks of professionals working in CBC and how they are interconnected with the institutional CBC. This paper is based on a mainly qualitative research of two different border regions: Andalusia, Algarve and Alentejo (AAA) and South Finland and Estonia (SFE). Nevertheless, the methodology is multi-method, using semi-structured interviews, with specific questions for applying a social network analysis. Conclusions point out different patterns of border relations in both border regions. In AAA, most of the cross-border relations are weaker and related to their professional involvement in institutional CBC. In SFE, border relations rely both on working and personal reasons. All of these cross-border relations imply a significant value as opportunities for social capital construction across the borders and, hence, for greater interaction and cross-border integration.     

Cross-platform program for likelihood-based statistical comparisons of mortality profiles on a triangular graph

The construction of mortality profiles to investigate age-at-death patterns is a typical component of most faunal analyses. While many methods exist for constructing and comparing mortality profiles, plotting the percentages of juvenile, prime, and old individuals on a triangular graph, or ternary diagram, remains a popular method for making comparisons. Typically, these comparisons are made visually, but because sample sizes are often small, any differences may be the product of sampling rather than meaningful contrasts in depositional history. To overcome this problem, here we present a likelihood-based method for making statistical comparisons of mortality profiles on a triangular graph, and we make available a cross-platform computer program that implements the method. Although we developed the method with mortality profiles in mind, in principle, it can be used to analyze any kind of artifact for which there are three distinct categories.     

The Middle and Later Stone Age faunal remains from Diepkloof Rock Shelter,Western Cape,South Africa

The faunal sample from the Middle Stone Age (MSA) and overlying Later Stone Age (LSA) deposits of Diepkloof Rock Shelter (Western Cape Province, South Africa) includes at least 40 taxa, mostly mammals, but also tortoises, snakes, birds (especially ostrich represented by eggshell), and intertidal mollusks. The LSA sample contains only species that occurred nearby historically, including domestic sheep, which LSA people introduced to the region by 1800 years ago. In contrast, like other Western Cape MSA faunas, the Diepkloof MSA sample has more species and it is especially notable for five large extralimital grazing species. These imply a greater-than-historic role for grasses in the local vegetation, particularly in the post-Howiesons Poort (latest MSA) interval where the grazers appear most abundant. Extreme fragmentation and dark-staining impedes analysis of the MSA bones, but cut-marks, abundant burning, and numerous associated artifacts suggest that people were the main accumulators. Rare coprolites imply that carnivores could have contributed some bones, and concentrations of small mammal bones, particularly near the bottom of the MSA sequence, suggest a role for raptors. Tortoise bones are common throughout the sequence, and the MSA specimens tend to be especially large, as in other MSA assemblages. The LSA specimens are smaller, probably because LSA human populations were denser and preyed on tortoises more intensively. The most surprising aspect of the Diepkloof assemblage is its marine component. The coast is currently 14 km away and it would have been even more distant during much of the MSA when sea levels were often lower. Intertidal mollusks, particularly black mussels and granite limpets, are concentrated in the LSA and in the Late and Post-Howiesons Poort layers. Only LSA shells are complete enough for measurement, and the limpets are small as at other LSA sites. The implication is again for more intense LSA collection by relatively dense human populations. Both the LSA and MSA deposits also contain bones of shorebirds and Cape fur seals. Whale barnacles and occasional dolphin bones indicate that MSA people scavenged beached cetaceans.     

Lagos leprosarium (Portugal): evidences of disease

In 2009, an archaeological intervention in the Valle da Gafaria (Lagos, Portugal) allowed the excavation of part of a leprosarium and an associated necropolis (15th–17th centuries). The individuals recovered were buried directly in the soil, in positions and orientations discordant to the prevailing Christian rules. The sample is made up of eleven adult individuals of both sexes.     

Multiple traumatic dental injuries: a case report in a young individual from the Samnitic necropolis of Opi Val Fondillo (VI-V century BC; Central Italy)

Traumatic dental injuries, although apparently rare in archaeological populations, can be found under certain circumstances affecting the dentition in a variety of ways. This paper contributes to the paleopathology literature by reporting one case of dental trauma. Evidence for differentiating antemortem/perimortem dental trauma from postmortem damage is presented, and it is suggested that these injuries were sustained due to an accidental fall, supported by the morphology, location and extension of the injuries and characterization of the impact. These data provide a valuable information for a reconstruction of past behaviors in the Samnitic necropolis of Opi Val Fondillo (VI-V century BC; Central Italy).     

Fowling during the Gravettian: the avifauna of Pavlov I, the Czech Republic

This is the first article that describes in detail the bird remains from the Gravettian mega-site Pavlov I in the Czech Republic. More than 1000 bird bones represent at least 19 taxa, of which the most numerous are tetraonids including black grouse (Tetrao tetrix), willow grouse (Lagopus lagopus) and ptarmigan (Lagopus muta), and ravens (Corvus corax). The archaeological and biological contexts indicate that most birds were hunted by people in the vicinity of the site, possibly with the help of knotted nets made from plant fibres. We suggest that ravens were killed while feeding on carcasses and/or food remains that may have been disposed of intentionally, and feathers may have been used for arrow fletching. Human-modified bones indicate that birds were used not only for food but also as raw material for tools and decoration. Although mammals were certainly more important in the subsistence of the Gravettian people, it is clear that birds played a role in their culture. The location of Pavlov I enlarges the explanatory scope of the Broad Spectrum Revolution hypothesis to include higher latitudes north of the Mediterranean.     

Soluble Salts Amplify the Effect of Small Heterogeneities in the Structure of Porous Building Materials During Drying

Salt crystallization is a major cause of degradation in old buildings. One of the issues that stills need clarification is regarding the influence of the salts on the capillary absorption and subsequent drying of porous building materials. This article presents an experimental study that included capillary absorption and evaporative drying tests on two types of material (lime mortar and ceramic brick) using pure water or saturated solutions of six salts (sodium chloride, sodium sulfate, sodium nitrate, sodium carbonate, potassium nitrate, or potassium carbonate). The results of capillary absorption agree only roughly with the linear relationship, predicted by theory, between sorptivity and the square root of the ratio between viscosity η and surface tension σ of the solution (σ/η)^1/2. This poor agreement is probably due to material heterogeneity. The drying dynamics was regular and showed little dispersion between specimens, but only for the uncontaminated materials. Indeed, the drying dynamics of the salt contaminated materials was often irregular or diverged among similar specimens, and the same happened with their salt decay patterns. The main conclusion is that soluble salts can amplify the effects on drying of the small structural heterogeneities that porous building materials normally depict.     

A hoard of Nilotic nacreous shells from Egypt to Jericho (Early Bronze II, 3000–2800 BCE): Their finding,content and historical archaeological implications

ABSTRACT

The Tell es-Sultan, ancient Jericho, is amongst the earliest “cities” that rose in the Southern Levant between the end of 4th and the beginning of the 3rd millennium BCE. The site is being excavated, studied and rehabilitated for tourism by Sapienza University of Rome and the Palestinian Ministry of Tourism and Antiquities since 1997. In 2017, during the 13th season of excavation, an unexpected discovery occurred: five Chambardia rubens shells have been found piled up in a dwelling unit dating back to the Early Bronze Age IB-II. The discovery is a tangible evidence of trade and cultural interconnections between the Southern Levant and Egypt, as these shells belong to a species that is only been found to live in the Nile. Moreover, chemical analysis, and thorough Scanning Electron Microscopy examination revealed that the shells contained Manganese Dioxide, an inorganic compound used as make-up ingredient in ancient Egypt, and available in the ores of the Sinai. These findings strongly support the existence of a link between the urban rise in EB IB-II through international trade of luxury goods, and are suggestive of the emergence at Jericho of a ruling elite that was influenced by Egypt.
