Investigation of Organic Materials From the ‘Royal’ Burials of Xiongnu (Noin‐Ula,Mongolia) by Srxrf and XAFS Methods

The burials of famous Xiongnu people are a unique source of information about Xiongnu culture, due to the variety of organic findings. SRXRF analysis of hair, clay, bones, teeth and woollen cloth was carried out. An anomalously high copper content was observed in all hair samples, whereas the levels of copper in bone and clay were low. To define the hair morphology and the elemental distribution in the hair cross‐section, high‐resolution X‐ray computed tomography (HRXCT) and energy‐dispersive spectroscopy (EDS) with scanning electron microscopy (SEM) were used. The X‐ray absorption fine‐structure method (XAFS) was applied to determine the local copper environment. The majority of the copper species in the hair and enamel samples are present as Cu²⁺ cations in a distorted octahedral (4 + 2) coordination, surrounded by light ligands (oxygen/nitrogen). A similar distorted octahedral coordination is typical for both inorganic mixed oxide/hydroxide Cu nanosystems and metal–organic Cu complexes (with oxygen/nitrogen).     

The technology of Copper Age funerary pottery from Central Italy: An integrated study of compositional analyses and manufacturing traces

The paper focuses on ceramic vessels unearthed from Copper Age necropolises located in the area of the modern city of Rome and commonly attributed to the Rinaldone culture. The peculiar vessels' shapes, mainly associated with the consumption of beverages, their accuracy of manufacture and the very low impact of these ceramic morphologies in the coeval household assemblages lead to the study of such an apparently selected production through a multidisciplinary research. Petrographic analysis, X-ray fluorescence (XRF) and X-ray diffraction (XRD) integrated with the analysis of manufacturing traces and X-ray investigation suggest the transmission of technological choices, which remained unchanged over almost two millennia.     

Stable isotope analysis of the Inca mummy from Nevado de Chuscha (Salta,Argentina)*

This paper presents the carbon (¹³C/¹²C), nitrogen (¹⁵N/¹⁴N), oxygen (¹⁸O/¹⁶O), hydrogen (²H/¹H) and sulfur (³⁴S/³²S) stable isotope values measured in the hair of a female individual from north-western Argentina. The analysis of segments of this tissue allows for the recording of the diet and migratory changes with a short time resolution. The sample is from a mummified young female individual discovered in Chuscha mount, Salta province. It was found at more than 5000 masl, in a mountain sanctuary of the Inca expansion (capacochas). The paper discusses the paleodiet and mobility patterns of this individual in the period before her death, focusing on the isotopic variations in a limited time scale. The results indicate that the individual moved from a different region to the place where she was sacrificed. Furthermore, in the last year the individual was alive, a shift in the isotopic composition of the food consumed is detected: a variation in the importance of C₄ over C₃ resources is evident. The results are compared with the isotopic estimations for other children and young people recovered in archaeological contexts associated with capacochas to infer variability in the geographical trajectories covered during their last months of life.     

How network position interacts with the relation between creativity and innovation in clustered firms

Several previous studies have investigated different ways to stimulate creativity, since it enhances innovation. However, although creativity can be considered the main input of innovation, it is not enough by itself. In this paper, we study the effects of the cluster on the firm’s levels of creativity and innovation. How does the position of a firm in a cluster affect its outcome of innovation? Is it better to be in a central position or to be isolated? Based on the creativity, innovation and social network analysis literature, a conceptual model has been developed to explain the interaction between creativity and network centrality, and tested in the ceramic industrial cluster in Spain. Empirical findings support interaction effects between creativity and network centrality that moderate the results of innovation. The implication of these results in relation to creativity and innovation theory and practices are discussed.     

The trials and travails of the Islamic State in Pakistan

While Pakistan is in many ways an ideal location for transnational terrorist groups due to state weakness, Islamic State has had difficulty making headway in the country. In this article, the authors argue that Islamic State’s failures in Pakistan are due to competition from other groups. Drawing on the terrorist competition literature and interviews with Pakistani counterterrorism officials, the authors find that the presence of other groups in Pakistan meant there was little demand for what Islamic State offered. Islamic State relied on splinter groups and defectors for recruitment, which alienated mainstream groups and harmed the group’s capacity. Islamic State’s competition problems were exacerbated by its internationalist ideology, which was at odds with that of many groups in Pakistan, and allowed opposing groups to present themselves as reasonable alternatives to other actors. Despite Islamic State’s lack of success, it and its allies have still engaged in extreme violence in Pakistan as a result of attempts to outbid other groups. This article has implications for fighting terrorism in Pakistan and more generally.     

Facing the Greek junta: the European Community,the Council of Europe and the rise of human-rights politics in Europe

Abstract

In April 1967, a group of colonels seized power in Greece. Since Greece was a member-state of the Council of Europe and held an association agreement with the European Community, both organizations had to define their positions vis-à-vis the new military regime. Very soon, politicians in the parliamentary assemblies of both organizations started to cooperate with the aim of imposing sanctions on Greece. This article examines the inter-organizational dynamics between the European Community and the Council of Europe on Greece during the colonels’ regime. It argues that the European Community imported concrete policy positions and even normative ideas which had first emerged in the Council of Europe. In so doing, the Community prepared the ground for its future human-rights policies.     

Biostratigraphic Evidence Relating to the Age‐Old Question of Hannibal's Invasion of Italy,II: Chemical Biomarkers and Microbial Signatures

As discussed in Part I, a large accumulation of mammalian faeces at the mire site in the upper Guil Valley near Mt. Viso, dated to 2168 cal ¹⁴C yr., provides the first evidence of the passage of substantial but indeterminate numbers of mammals within the time frame of the Punic invasion of Italia. Specialized organic biomarkers bound up in a highly convoluted and bioturbated bed constitute an unusual anomaly in a histosol comprised of fibric and hemist horizons that are usually expected to display horizontal bedding. The presence of deoxycholic acid and ethylcoprostanol derived from faecal matter, coupled with high relative numbers of Clostridia 16S rRNA genes, suggests a substantial accumulation of mammalian faeces at the site over 2000 years ago. The results reported here constitute the first chemical and biological evidence of the passage of large numbers of mammals, possibly indicating the route of the Hannibalic army at this time. Combined with the geological analysis reported in Part I, these data provide a background supporting the need for further historical archaeological exploration in this area.     

Formation of Fluid Inclusions during Heat Treatment of Barremo‐Bedoulian Flint: Archaeometric Implications

At the end of the fifth millennium bc , the development of a specialized lithic industry in the Chassey societies of south‐eastern France and its dissemination as far as Catalonia and Tuscany attest to important socio‐economic changes in the Mediterranean Neolithic societies. The lithic production was made on barremo‐bedoulian flint that was heat‐treated to improve the sharpness of the tools produced. Microscopic observations of archaeological and geological, heated and unheated barremo‐bedoulian flint samples allowed us to highlight the heat‐induced formation of fluid inclusions. Microthermometry analyses showed that these inclusions contain pure H₂O, most probably resulting from the dehydration of length‐slow (LS) chalcedony and the closure of narrow pores, according to the model proposed by Schmidt et al. ( 2012 ). Our results enable us to estimate the heating temperatures used by Chassey artisans to ≈ 230°C. We also propose the ‘pressure cooker’ model to explain the migration of liquid water in flint nodules heated to 230°C. Then, we discuss the ability of a particular type of flint to be heat‐treated, and hence its value for Neolithic society, which depends on: (1) the amount of LS chalcedony that ensures the water release at relatively low temperature; and (2) on the total volume of porosity available to store the dehydration water.
