Extinct species identification from late middle Pleistocene and earlier Upper Pleistocene bone fragments and tools not recognizable from their osteomorphological study by an enhanced proteomics protocol

Ancient preserved molecules offer the opportunity of gaining a deeper knowledge on their biological past. However, the development of a proteomic workflow remains a challenge. The analysis of fossils must involve a low quantity of material to avoid damaging the samples. In this study an enhanced proteomic protocol was applied to 5-milligram samples of about 130,000-year-old mammalian bones ranging from the end of the Middle Pleistocene up to the earlier Upper Pleistocene, excavated from Scladina Cave (Sclayn, Belgium). Using sequence homology with modern sequences, a biological classification was successfully achieved and the associated taxonomic ranks to each bone were identified consistently with the information gained from osteomorphological studies and palaeoenvironmental and palaeodietary data. Amino acid substitutions on collagens were identified, thus providing new information on extinct species sequences and helping in taxonomy-based clustering. Considering samples with no osteomorphological information, such as two fragments of bone retouchers, proteomics successfully identified the families providing paleontologists new information on these objects. Combining osteomorphology studies and amino acid variations identified by proteomics, one of the retouchers was potentially identified as belonging to the Ursus spelaeus species.     

Commercial Archaeology and 3D Web Technologies

ABSTRACT

This contribution summarizes the multiple uses of 3D web technologies in commercial archaeology. Considering the breadth of this topic, we will describe each different branch of these technologies with the example of case studies based on work of the Italian company Arc-Team. Our overview begins with 3D visualization for scientific purposes, showing a project funded by the Autonomous Province of South Tyrol (Italy) in order to improve knowledge about WWI. Second, we analyze a similar project, funded by the Autonomous Province of Trentino (Italy), but with the aim to increase tourism at a high alpine WWI site. The third example is the development of another prototype for tourism: a 3D web-map for the cultural valorization of the historical border (1753) between the region Tyrol and the Most Serene Republic of Venice. In the forth case study, we discuss the implementation of 3D within web platforms for archaeological project management of RAPTOR (Ricerca Archivi e Pratiche per la Tutela Operativa Regionale), a webGIS developed to aid in preservation and conservation efforts of cultural heritage for the Italian Ministry of Cultural Heritage and Activities and Tourism (MiBACT). Fifth, we explore recent uses of 3D models for web-coworking during the process of excavation management, thanks to the developments of real-time 3D acquisition techniques based on SLAM algorithms and archeorobotic devices. Finally, 3D web-coworking is also analyzed illustrating some simple web tools that afford rapid feedback in data visualization, considering not only excavation field-work but also exploration projects. This overview, based on six different case studies, represents the four fields in which 3D web technologies are currently used in commercial archaeology: scientific communication; tourism improvement; preservation of cultural heritage; and real time field-work management. Some specific topics such as tourism improvement and field-work management are investigated in greater depth in order to allow us to analyze variables deriving from customer requests (e.g. restrictions regarding sensitive geolocation or preferences for specific web platforms) and from differences among data acquisition technologies based on various sensors.     

La mode du ping-pong en France en 1902: une autre façon de questionner les classiques transferts culturels dans le domaine du sport

This study offers to follow the path of a parlour game and allows to seize the cultural transfers of this physical practise and to measure the part of the ambient anglomania in its reconfiguration in France at the beginning of the twentieth century. The ping-pong become a fashion within the French high society in 1902. By joining the bourgeois codes, this parlour game contributes to the perpetuation of the uses of this select population far from the effort of English sport. This fashion seduces because it’s not only perpetuation of the social conventions of elites. It’s also built on the idea of emancipation which the impossible meets between men and women symbolise. Fashion is surprisingly fed with paradox.     

Innovation,knowledge and relations – on the role of clusters for firms’ innovativeness

ABSTRACT

For more than two decades, theories on regional clusters have inspired economic and structural policies at the European, national and regional levels. Based on the assumption that clusters generate innovation, policy-makers at all levels of governance have adopted instruments and mechanisms to stimulate, resource and sustain clusters. Despite the considerable attention paid to the clustering phenomenon, empirical evidence on to what extent firms’ innovation activities benefit from operating in clusters is scarce and inconclusive. This paper contributes to the micro-foundation of clustering effects by examining the characteristics and activities of cluster firms in relation to their innovativeness. Bridging innovation, management and cluster theories, it is argued that structural and relational embeddedness, relational capital and absorptive capacity influence clustered firms' innovativeness. Partial least-squares structural equation modelling of data from 104 firms in two software and information technology service sector clusters reveals that firms’ structural embeddedness (i.e. frequency of interactions) in clusters and external networks facilitates innovation cooperation. Firms’ absorptive capacity reinforces this positive effect of cluster-internal interactions on innovation cooperation. Results also suggest a substitution effect of trust as relational control mechanisms for formal control mechanisms within the cluster. However, the study finds no significant impact of firms’ innovation cooperation within the cluster (i.e. relational embeddedness) on their innovation success.     

Leontief's “Environmental Repercussions and the Economic Structure…” Revisited: A General Equilibrium Formulation

A 1972 paper by Leontief on an input-output model with pollution removal activity as an explicit sector is reformulated as a computable general equilibrium model. The advantage of this reformulation is that substitution and rational behavior by producers and consumers can be modeled and prices are rendered endogenous. The two approaches are contrasted regarding the consequences of policy changes about taxation and technological improvements.     

Historical ecology coming of age

Historical ecology is a research program that in earnest has emerged within anthropology since the turn of the millennium. This essay offers a short outline of historical ecology and, on the basis of a review of four volumes published over the last decade, discusses several key issues in the historical ecological analyses of socio-environmental relations. It is argued that historical ecology (1) emerged as a concept in different, but related, discursive contexts, (2) coalesced in North American anthropology and anthropological archaeology, and (3) subsequently cross-fertilized and diversified in new academic milieus successfully addressing previously unconsidered research questions in novel ways.     

Archibald Campbell and the Committee for Purity of Doctrine on Natural Reason,Natural Religion,and Revelation

Summary

This article discusses Archibald Campbell's (1691–1756) early writings on religion, and the reactions they provoked from conservative orthodox Presbyterians. Purportedly against the Deist Matthew Tindal, Campbell crucially argued for two claims, namely (i) for the reality of immutable moral laws of nature, and (ii) for the incapacity of natural reason, or the light of nature, to discover the fundamental truths of religion, in particular the existence and perfections of God, and the immortality of the soul. In an episode that had its peak in 1735 and 1736, a Committee for Purity of Doctrine of the Church of Scotland scrutinised Campbell's writings. It attacked the second claim as contradicting Calvinist doctrines concerning the universal guilt of mankind after the Fall, and the first claim as contradicting doctrines concerning justification and salvation, and as supporting Deism. The study of this episode reveals new aspects of how the struggle to define orthodoxy crystallised in philosophical and theological debates in Scotland at the dawn of the Enlightenment, and before the rise of the Moderates.     

Conflict and State Development in Ancient Tonga: The Lapaha Earth Fort

Warfare is often considered as a key factor in the formation complex societies, but in the Pacific archaeological evidence for inter-group conflict during political centralization is rare. Most earthwork forts in Tonga are assumed to have been built in the nineteenth century when the traditional system of rulership collapsed, yet few forts on Tongatapu have been excavated or 14C dated. A fort in the chiefly center of the ancient Tongan state was mapped with theodolite and LiDAR, and excavated. Radiocarbon and traditional history indicate the fort known as the Lapaha Kolotau was made in the fourteenth century AD at the same time that chiefly architecture was being built at an unprecedented scale at the new elite center. The construction of an earthwork fort provides the first evidence that political centralization in Tonga was likely to have been contested.
