Charcoal from a prehistoric copper mine in the Austrian Alps: dendrochronological and dendrological data,demand for wood and forest utilisation

During prehistory fire-setting was the most appropriate technique for exploiting ore deposits. Charcoal fragments found in the course of archaeological excavations in a small mine called Mauk E in the area of Schwaz/Brixlegg (Tyrol, Austria) are argued to be evidence for the use of this technology. Dendrochronological analyses of the charcoal samples yielded calendar dates for the mining activities showing that the exploitation of the Mauk E mine lasted approximately one decade in the late 8th century BC. Dendrological studies show that the miners utilised stem wood of spruce and fir from forests with high stand density for fire-setting and that the exploitation of the Mauk E mine had only a limited impact on the local forests.     

Evidence for “Celtic migrations”? Strontium isotope analysis at the early La Tène (LT B) cemeteries of Nebringen (Germany) and Monte Bibele (Italy)

Strontium isotope analysis on human remains from the Iron Age (4th/3rd century BC) cemeteries of Nebringen, Germany and Monte Bibele, Italy were carried out to investigate the role of residential changes during the period of the historic “Celtic migrations”. From an archaeological perspective, the location of the cemeteries in the Celtic core (Nebringen) and expansion area (Monte Bibele), and the distinctive development of their material culture, suggest that the buried populations had differing mobility rates. On the contrary, the strontium results indicate that only few individuals were mobile or non-local. There is, however, a difference in variation of strontium isotope ratios between the two studied cemeteries, presumably caused by differing geological conditions. In Nebringen changing use of cultivated land in a geologically heterogeneous environment most likely caused varying strontium isotope ratios even within the same jaw, while individual mobility over longer distances can also not be excluded. In Monte Bibele the range of strontium isotope ratios is narrow, and this may be explained by a community living in the same village and using the same agricultural resources. For various prehistoric time periods it has been suggested that some population groups were more mobile than others, for example because they had special social roles. In the two cemeteries studied here, males have slightly more often a non-local birthplace or moved during childhood. In contrast, females had isotope signatures which are more consistent with the local geological environment. Male mobility is, however, not correlated with burial as a warrior, and patrilocal residential patterns were not observed among females. Foreign and local items are found with isotopically local and non-local individuals and objects per se do not indicate descent. The motives for residential changes were, therefore, varied and not constrained to a specific area or population group. The presented dataset provides details on the way of life and land-use in the Celtic communities, for which information is otherwise absent.     

Misunderstanding Executive Representation: Causes and Consequences

Prevailing beliefs about executive representation tend to rely on implicit assumptions that are not carefully examined. I argue that there is confusion regarding both the type of representative role adopted by presidents, and the legitimacy of the representative role of the executive. Presidents are often associated with the "virtual" form of representation, which is consistent with the symbolic role of the president, but the fact that the president, as an elected official, satisfies the requirements of an actual representative is overlooked. Identifying and distinguishing the representative roles in the executive demonstrates the conflict between the two. The institution links the executive with a very large, heterogeneous constituency, requiring presidents to address individual interests, while at the same time endowing the office with national leadership qualities that call for attention to a broader, national interest. An examination of executive representation demonstrates the structural nature of both representative roles, which, while not easily reconciled, are fundamental institutional characteristics.

Rich Pickings: An Analysis of Opportunistic Behaviour at Rangitoto Island,Aotearoa/New Zealand

Rangitoto Island, Aotearoa/New Zealand, is the location of a graveyard of abandoned vessels and three communities of baches (circa 1910s–1930s)—small and modest holiday homes. In 2014, an archival and archaeological investigation of 11 discarded watercraft located at Boulder Bay and the bach communities of Beacon End, Rangitoto Wharf and Islington Bay revealed evidence of salvage and reuse of abandoned vessel materials in the construction, modification and use of the island’s baches. This evidence in turn provides insight into opportunistic behaviours of communities unassociated with the maritime industries that created ships’ graveyards, and consequently affords a more well-rounded understanding of post-depositional site formation processes. Influenced by social and economic impacts, the Rangitoto Island bach communities’ resourcefulness enhances our knowledge of behaviours towards ships as sources of material.     

Lead isotope analysis of intra‐skeletal variation in a 19th century mental asylum cemetery: diagenesis versus migration

Living bone sequesters environmental lead (Pb) from both inhalation and ingestion, providing a record of Pb exposure over a lifetime. Questions about the effects of diagenesis and how to remove them have hampered most isotopic and elemental determinations. As a result, researchers often restrict their analyses to tooth enamel, despite its limitations. We report Pb isotopes in teeth and bones in a frontier population of 15 individuals from a late 19th century mental hospital graveyard in Pueblo, Colorado, a town active at that time in the smelting of ores. Analysis of lead isotopes sequestered in healing bone from rib fractures gives an isotopic fingerprint from the last few months of individual's lives. When bone tissues or teeth from different stages of life are analysed, life history trajectories such as migration routes can be developed which are partially self‐correcting for diagenesis.
