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.     

Information, institutions et temporalité quelques remarques critiques sur l'usage de la nouvelle économie de l'information en histoire

The paper reviews the main «applications» to economic history of neo-institutionalist and game theories. The analysis of labor, land and credit markets as well as their implications for the theory of development are equally discussed. The author then discusses the main game theories, their hypotheses and assertions in order to elucidate their historiographical uses. The last part of the paper introduces more complex notions of rationality, while distinguishing between information and learning; it finally suggests an heuristic scheme able to integrate certain elements of the economy of information and games into historical notions of time.     

A case of Madelung's deformity in a skeleton from Nuragic Sardinia

The case reported here refers to the skeletal remains of a mature adult male found in a collective grave known as ‘Giant's tomb’ located near Donori (Sardinia) and dating to the end of the Bronze Age. The skeleton showed bilateral shortening of the forearm associated to radial bowing, marked deformations at the radio‐ulnar distal joints and subsequent posterior dislocation of both ulnae. The whole alterations fit well with a diagnosis of Madelung's deformity, a rare form of mesomelic dysplasia. At present, this case is the most ancient evidence of Madelung's deformity.

Modeling the Seismic Response of Modern URM Buildings Retrofitted by Adding RC Walls

Modern unreinforced masonry buildings with reinforced concrete slabs are often retrofitted by inserting reinforced concrete walls. The main advantages of this technique are the increase in strength and displacement capacity with respect to masonry structures. This article presents two modeling approaches for evaluating such structures: a shell-element model and a macro-element one. The objective is to formulate practical recommendations for setting up a macro-element model using as input the geometry of the structure and results from standard material tests. Structural configurations of masonry buildings, in which the insertion of reinforced concrete walls is an efficient retrofit technique, are also investigated.     

Escaping Violence,Seeking Freedom: Why Children in Bangladesh Migrate to the Street

In Bangladesh, as in many developing countries, there is a widespread belief amongst the public, policy makers and social workers that children ‘abandon’ their families and migrate to the street because of economic poverty. Ignoring and avoiding mounting evidence to the contrary, this dominant narrative posits that children whose basic material needs cannot be met within the household move to the street. This article explores this narrative through the analysis of detailed empirical research with children in Bangladesh. It finds that social factors lie behind most street migration and, in particular, that moves to the street are closely associated with violence towards and abuse of children within the household and local community. These findings are consistent with the wider literature on street migration from other countries. In Bangladesh, those who seek to reduce the flow of children to the streets need to focus on social policy, especially on how to reduce the excessive control and emotional, physical and sexual violence that occur in some households. Economic growth and reductions in income poverty will be helpful, but they will not be sufficient to reduce street migration by children.     

Cultural Heritage Documentation and Conservation: Three-Dimensional (3D) Laser Scanning and Geographical Information System (GIS) Techniques for Thematic Mapping of Facade Stonework of St. Nicholas Church (Pisa,Italy)

This article reports the mapping of the stones, including marbles and brick masonry, used for building the facade of the medieval Church of St. Nicholas (XI century ad), one of the most interesting churches in Pisa, due also to the nearby famous octagonal bell tower. Mapping of stone materials was performed using a computer-aided design (CAD)/geographical information system (GIS) software package for storing and processing spatial information of the ashlars, obtained using three-dimensional (3D) laser-scanning data, combined with high-resolution images, and stone-to-stone observations. Based on collected data, the facade of the Church of St. Nicholas appeared mostly composed of rocks belonging to the metamorphic Tuscan sequence, quartzites, and marbles from Mt. Pisano area. Other types of rocks were also observed, as black limestones quarried at some kilometers northwest from Pisa in the Monti d’Oltre Serchio area, white Apuan marbles and Macigno sandstones. Conversely, intarsia appeared mainly made up of serpentinite and, subordinately, red limestones laid in white Apuan and Mt. Pisano marbles.     

Ruinismo: the Catholic Church in Italy from ‘mediation culture’ to the Cultural Project

It is only seven years since Monsignor Camillo Ruini resigned from his role as President of the Italian Episcopal Conference (CEI), yet it feels much longer. The tempestuous events that marked Silvio Berlusconi's decline, on one hand, and the election of Pope Francis to the Holy See, on the other, have made such an impression on recent Italian history that seems to leave no time for reflection on what has happened over the last twenty years. This article explores how, during this time, Cardinal Ruini has re-fashioned the relations between the Catholic Church and Italian politics, following a pattern that has come to be known as ‘ruinismo’. The essay follows the development of the theological-political line of the Conference, from the “mediation” of the “Catholic Party”, the Christian Democrats (DC), to the “policy of presence” of politically committed Catholics, defined in these terms by the ecclesiastical congress in Loreto in 1985 and fully carried out under Ruini's management, with the backing of Berlusconi's governments. The aim is to establish whether and to what extent the “Ruinian” rule may be regarded as the consequence of mainstream Catholic politics of the 1980s and, equally, as a response to the cultural and political transformation brought about by the upheavals of the corruption scandals of 1989–91. Only from this long-term perspective is it possible to determine whether Ruini's exit has brought an end to ruinismo.     

Broca and Charcot’s Research on Jacques Inaudi:The Psychological and Anthropological Study of a Mental Calculator

In the nineteenth century, French scientific institutions became interested in young “mental calculators,” arithmetical prodigies able to quickly and accurately perform complex mental calculations. The first scientists to study mental calculators were phrenologists who sought to prove the existence of a calculating organ in the frontal lobe. Paul Broca introduced one such mental calculator, Jacques Inaudi, to the Anthropological Society of Paris in 1880. Broca attributed extraordinary faculty for mental calculation to memory functioning (the psychological hypothesis) rather than physiological difference (the phrenological hypothesis). In 1892, prominent French Academy of Sciences member Jean-Martin Charcot produced a noteworthy study of Inaudi on the organization’s behalf. Charcot observed that Inaudi called upon auditory memory rather than visual memory in his mental calculations, unlike most mental calculators who preceded him. Like Broca, Charcot was skeptical of the phrenological hypothesis, though he noted that Inaudi’s skull was markedly plagiocephalic. Interestingly, anthropological examination of Inaudi is consistent with the themes of modern cognitive neuroscience. Thus, Charcot seems to have anticipated present research on the localization of mental calculation and memory for numbers.
