Bone diagenesis in the European Holocene II: taphonomic and environmental considerations

We have applied cluster analysis to mercury intrusion porosimetry data from 219 archaeological bones (121 human and 98 animal) and soil chemistry data from 219 accompanying soil samples (1 per bone sample), to investigate the influence of soil chemistry on bone preservation. The samples chosen for the study were obtained from sites ranging in time from the pre-modern to the Mesolithic and were representative of burial environments across Europe (from the Baltic to the Mediterranean). These results represent the single largest database for archaeological bone preservation in the European Holocene to date and demonstrate the potential for large-scale diagenetic studies to help develop long term preservation strategies for our European heritage. Despite the variety of sites and environments, bones could be categorised into only four main diagenetic types. Furthermore, soil chemistry appears to significantly affect only one type of preservation, the pathway characterised by loss of mineral. In neutral to basic soils, taphonomy and in particular the differences between the treatment of human and animal remains, becomes the dominating factor in determining preservation. Using these results, strategies for heritage management of archaeological sites can be suggested; grouping sites into those requiring immediate excavation and those where in situ preservation is viable.     

Are Teeth Better? Histological Characterization of Diagenesis in Archaeological Bone–Tooth Pairs and a Discussion of the Consequences for Archaeometric Sample Selection and Analyses

Teeth are often the preferred source material for isotopic and genetic assay involving ancient biomolecules. The assumption is that dental tissue preserves better due to its anatomically protected location, the enamel cap, and lower porosity compared to bone. However, this assumption has not been widely tested. Some similarities in diagenetic processes are to be expected due to similarities in structure and chemical composition of dentine and bone. This has led to the suggestion that bone can be used as an indicator of dental preservation, as a pre‐screening technique in the selection of suitable samples for biomolecular studies. Thus, direct testing of the correlation between bone and tooth preservation and diagenesis is needed. This paper reports the results of the histological characterization of diagenetic alterations within 25 human femur–tooth pairs, from a Medieval to modern (AD 1850) cemetery in Eindhoven, the Netherlands. The results showed that teeth do indeed preserve better overall, but not always, and that this was dependent on the main diagenetic factor(s) at the burial location. Furthermore, good correlations are found between the microstructural preservation of bone and teeth; similar processes of decay were observed within bone and teeth of the same individual. Overall, the study demonstrated that histological analysis of bone is useful for the identification of degradation processes that affect biomolecular preservation in skeletal material. In this way, sample selection and analytical strategies can be optimized. Copyright © 2013 John Wiley & Sons, Ltd.     

Insecurity and Pastoral Development in the Sahel

In this article it is argued that conventional agro-ecological and organizational concepts used in pastoral development are strongly biased towards the formulation and enforcement of norms. This leads development experts to attempts to control pastoralists and their herds. The policies and development interventions based on these assumptions have been largely unsuccessful. As a consequence attention for dryland areas and pastoral development has declined among researchers and development agencies. An important reason for this failure is the fundamental misfit between these normative concepts and the reality of dryland ecosystems and pastoral society. In order to show this, an alternative view on rangeland ecology and pastoral society is presented, supported by a case study of Fulbe pastoral society in dryland Central Mali. The authors argue that approaches to pastoral development must be revised in the direction of the dynamics inherent in the pastoral way of life.     

Indentured servitude and convict labour in the Danish-Norwegian West Indies, 1671–1755

The article explores how indentured servitude and the use of convict labour began and evolved in the Danish-Norwegian West Indies in the period 1671–1755. It examines the intentions and realities behind indentured servitude and convict labour on the islands, and compares these with the workings and use of indentured servants in the British West Indies.

Similar to conditions in the British West Indies, the lowest social strata of white society in the Danish-Norwegian West Indies consisted of a small population of convicts and indentured servants. The use of these groups as part of the labour force took place from the onset of colonisation in 1672 until 1755, the period in which the islands were governed by the West Indian and Guinean Company, WIGC (Vestindisk-Guineisk Kompagni). The analysis reveals that the importation and deployment of indentured servants and convicts can be divided into two distinct periods. Until 1700, the objective of the WIGC was to provide cheap labour for the colony. After 1700, however, the aim was to recruit qualified personnel and to secure the planters against slave rebellion by increasing the white Danish population. As convicts provided neither qualifications nor security, convict transportations to the Danish-Norwegian West Indies ceased after 1700. After 1755, when the Danish-Norwegian Crown purchased the colonies from the WIGC, Danish convict labour and indentured servants were no longer imported to the colony. By contrast, in the British West Indies, imports of indentured servants and convicts continued to play a significant role.

The article explores the physical and legal conditions of the indentured servants and convicts, who constituted the lowest social group in white colonial society and were in some respects considered slaves.     

Ṭūsī Reloaded: Ismāʿīlī Paths of Sufi Wayfaring and Sufi Paths of Ismāʿīlī Apophaticism

Much ink has been spilled on the tumultuous life and works of Na?īr al-Dīn ?ūsī. This paper re-evaluates his connections with Sufism and Ismā?īlism, and challenges the reduction of the former to a late interest, and the latter to an early affiliation abandoned in the wake of the Mongol invasion. The paper argues that Sufi and Ismā?īlī themes, sources, and ideas are in an organic interpenetration in ?ūsī’s works throughout his career. While his early Ismā?īlī eschatology has a fundamentally Sufi nature, his late Sufi treatise adopts the key components of Ismā?īlī negative theology of the divine nature. The case of ?ūsī illustrates that the Ismā?īlī double negation was preserved in Iran and Central Asia, and put into creative interactions with Sufism in the thirteenth century.     

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.     

Vertical Politics in Horizontal Policy Networks: Framework Setting as Coupling Arrangement

Horizontal governance arrangements potentially conflict with the very principles of the representative democracy and its political institutions. This conflict manifests itself in the interaction between representatives and the executive power: Although the former has the formal power to decide upon policies and to check their implementation, the latter participates in horizontal networks and therefore has more resources to influence the content, evolvement, and outcomes of the policy process. This erodes the power position of representatives. Framework setting is commonly suggested as an arrangement for representatives to enhance their grip on policy processes. The authors of this contribution examine the effects of framework setting as coupling mechanism between horizontal networks and vertical politics in six policy processes in a Dutch province. Based on network theory and research findings, they suggest redefining the concept of framework setting in order to make it more attuned to the complex, interdependent, and dynamic nature of policymaking in networks.
