Immersive Visualization and Curation of Archaeological Heritage Data: Çatalhöyük and the Dig@IT App

Advanced data capture techniques, cost-effective data processing, and visualization technologies provide viable solutions for the documentation of archaeological heritage and material culture. Work at the UNESCO World Heritage site of Çatalhöyük has demonstrated that new digital approaches for capturing, processing, analyzing, and curating stratigraphic data in 3D are now feasible. Real-time visualization engines allow us to simulate the stratigraphy of a site, the three-dimensional surfaces of ancient buildings, as well as the ever-changing morphology of cultural landscapes. Nonetheless, more work needs to be done to address methodological questions such as follows: can three-dimensional models and stratigraphic relationships, based on 3D surfaces and volumes, be used to perform archaeological interpretation? How can a 3D virtual scenario become the interface to cultural data and metadata stored in external online databases? How can we foster a sense of presence and user embodiment in the simulation of ancient cities and archaeological sites? This article aims to provide viable solutions to the methodological challenge of designing a comprehensive digital archaeological workflow from the data acquisition and interpretation in the field to a three-dimensional digital data curation based on interactive visualization, searchable 3D data, and virtual environments. This work describes the results we achieved developing the application Dig@IT, a multi-platform, scalable virtual reality tool able to foster archaeological data analysis, interpretation, and curation in a realistic and highly interactive virtual environment.     

Structural Investigation of 18th-Century Ogival Masonry Domes: From Carlo Fontana to Bernardo Vittone

In this study a structural investigation on the ogival masonry domes is performed with particular attention to the significant debate between mathematicians and architects mainly of the French and Italian schools that characterized the 18th century. In this period, analytical approaches to investigate the static of dome structures were developed concurrently for the affirmation of the proportional methods, as reported in several architectural treatises in which graphical constructions for the design of masonry domes can be found. It is well known that Carlo Fontana, in 1694, was the first to show in detail the geometrical rules for the design of a masonry dome. Later, in 1760, the Italian architect Bernardo Antonio Vittone proposed some variations to the rules written by Fontana in order to increase the height of the dome and the slope of the meridian section at the intersection with the lantern. In this study, Vittone’s dome has been analyzed and compared with Fontana’s dome by means of an analytical approach that also considers the influence of the lantern at the top. The obtained results confirm that Vittone’s rules lead not only to architectural, but also structural improvements.     

Women’s changing domestic responsibilities in neoliberal Africa: a relational time-space analysis of Lesotho’s garment industry

Since 2001 when Lesotho embraced the neoliberal African Growth and Opportunities Act that offers preferential access to the US market, its garment industry has expanded dramatically to become the nation’s leading employer. Elsewhere, large-scale employment of women in low-paid factory jobs has entailed spatial restructuring of gender and age relations. Lesotho is a distinctive context, with socio-spatial relations historically adjusted to male labour migration, high levels of contemporary male unemployment and alarming AIDS prevalence. Based on semi-structured interviews with 40 female factoryworkers and 37 dependents, this article applies a relational time-space analysis to explore how financial and spatio-temporal aspects of factory employment articulate to alter women’s relationships with those for whom they have culturally determined responsibilities: their children, those suffering from ill health and their (generally rural) home communities. The analysis highlights that such employment is not merely adding to women’s responsibilities, but transforming how they are able to undertake social reproduction, as practical, social and emotional roles are converted to largely financial obligations.     

Participatory Feedback and Dissemination with and for Children: Reflections from Research with Young Migrants in Southern Africa

In this contribution we discuss the process of feedback and dissemination that we adopted following research with children affected by AIDS in southern Africa. We outline our reasons for engaging in detailed feedback and dissemination, distinguishing between active or passive processes and discuss the participatory methods we adopted. Through our reflections we consider feedback as an obligation to participants and dissemination as a potential agent of social change. In addition we evaluate the effectiveness with which we were able to truly incorporate the voices of young people in our dissemination and relinquish control of the outcomes to make them available for action among policy-makers. In conclusion we highlight that active dissemination, although not able to guarantee that research recommendations will be acted upon, at the very least opens dialogue and enhances understanding among those able to implement action.     

Tracing Process to Performance of Collaborative Governance: A Comparative Case Study of Federal Hydropower Licensing

Despite collaborative governance's popularity, whether collaboration improves policy performance remains uncertain. This study assesses the link between collaborative decision making and licensed environmental management protocols in the Federal Energy Regulatory Commission's (FERC's) process for licensing hydropower facilities in the United States. Using results from a previous study of FERC relicensing (Ulibarri, forthcoming), one high‐, one medium‐, and one low‐collaboration case were selected. Using documents including meeting minutes, public comments, and issued licenses, I assessed collaboration and license outputs, then conducted process tracing to examine whether and how differences in collaboration produced differences in license quality. High collaboration resulted in jointly developed and highly implementable operating regimes designed to improve numerous resources, while low collaboration resulted in operating requirements that ignored environmental concerns raised by stakeholders and lacked implementation provisions. These results support the hypothesis that collaboration can improve environmental outcomes, revealing the pragmatic value of collaboration.

From Alliance to Tutelage: A Historical Analysis of Manchu-Mongol Relations before the Qing Conquest

Before 1644, the Manchu rulers pursued a deliberate policy of alliances with the southern (later “Inner”) Mongol tribes. In the 1630s the system of treaties and alliances gave way to the creation of the League-Banner system, the jasaq system, and the Lifan Yuan. The new territorial and political organization meant that the southern Mongols, while retaining a degree of autonomy, became subjects of the Qing dynasty. This essay explores the historical circumstances of the transformation of the relationship between Manchus and Mongols from partnership to subordination. It also aims to explain the political principles deployed by the Manchus in the redefinition of their relationship with the Mongol elites. More specifically, the essay proposes that the new forms of administration of Inner Mongolia stemmed from a condition of “tutelage.” Tutelage was not simply imposed by the Manchus upon their erstwhile allies, but actively sought by Mongol aristocrats in the context of the intra-Mongol wars carried out by the Čaqar leader Ligdan Khan.     

Remote sensing techniques for reconstructing a vast Neolithic settlement in Southern Italy

The combined application of remote sensing techniques is often the most effective way for deepening the knowledge on very large archaeological sites (several hectares). In particular, geophysics and aerial photography could yield very detailed information on buried structures not only outlining their location but also, in many cases, defining their planimetry. Moreover, the accurate geocoding of different data sets and the use of GIS for their integration allow to extract the most comprehensive information from a combined study.
