The Poor Law of old England: institutional innovation and demographic regimes

The striking improvement in life expectancy that took place in England between the Middle Ages and the seventeenth century cannot be explained either by an increase in real wages or by better climatic conditions. The decrease in the risk of utter destitution or of death from famine that was evident on the eve of the Industrial Revolution stemmed, in part, from institutional changes in the old poor law, which began to take shape and become effective early in the seventeenth century.     

Investigation of chemical changes in bone material from South African fossil hominid deposits

The bone fragments of the Australopithecus Africanus from the dolomitic cave in the Cradle of Humankind in South Africa have been studied by the use of several spectral techniques. The aim was to establish their degree of preservation and possibilities of inferring the life conditions from them. X-ray diffraction studies revealed the transformation of the mineral components partially into fluoroapatite form with addition of goethite, birnessite and quartz phases and with surprisingly well preserved collagen remains. Several important chemical elements were detected by using the electron (EPMA) and synchrotron-based X-ray fluorescence (XRF) microprobes. Among them, Sr and Zn were distributed in a way following the distribution of Ca, the main element of the bones. We suspect the immanent crystallographic substitution of Ca in this case in native bone. Iron followed the distribution of Sr but while Sr is distributed in a continuous way in more rigid locations, iron occurs mainly in the edge zones of the bones and in spot-like inclusions inside. Some part of the spots located in a very edge of bone is also filled with Mn and Cu. It suggests that the porosity and fracture of bones plays a more significant role in the localization of Fe, Mn and Cu. They also form a rigid thin layer (100–250 μm) avoiding further penetration. As (as AsO₄³⁻?) distribution pattern is unique and seems to occur in those locations where the concentrations of Sr are small. The conditions for bone penetration as determined from Eh-pH diagrams suggest that is rather impossible to preserve the organic matter in locations of Mn and also that Mn and Fe hardly can meet in the same spots.     

Age estimation by tooth/pulp ratio in canines by peri-apical X-rays: reliability in age determination of Spanish and Italian medieval skeletal remains

Estimation of age at death is an unavoidable step in the process of human identification, both in forensic practice and in the anthropological and palaeopathological study of skeletal remains. In several cases, in which medical or demographic records are completely lacking, a reliable estimation of the age at death becomes very important. Skeletal remains from archaeological contexts suffer from several biasing factors such as post-mortem changes, taphonomy and various burial practices depending on age, sex and social status of the deceased persons.     

The face of the poet Dante Alighieri reconstructed by virtual modelling and forensic anthropology techniques

This paper describes the multi-disciplinary approach to reconstruct the face of Dante Alighieri (1265–1321). Since Dante's sepulchre will be opened in 2021, the reconstructive process is based on morphological and metric data collected on the poet's cranium during the formal identification of his remains in 1921 by the anthropologist Fabio Frassetto, as well as on the resulting plaster model. Starting from this plaster model and a morphologically compatible reference mandible, since the original mandible was never found, a 3D digital model of the complete skull was obtained by reverse engineering and virtual modelling techniques. The most important aspect in this work was the method of virtual modelling proposed for the ex novo generation of the mandible. The physical model of the skull (cranium + mandible) was then produced by means of a rapid prototyping system. This model was finally used to recreate Dante's face via traditional facial reconstruction techniques currently used in forensic anthropology.     

Convergence in Cold War Physics: Coinventing the Maser in the Postwar Soviet Union

At the height of the Cold War, in the 1950s, the process of parallel invention of masers and lasers took place on the opposing sides of the Iron Curtain. While the American part of the story has been investigated by historians in much penetrating detail, comparable Soviet developments were described more superficially. This study aims at, to some extent, repairing this discrepancy by analyzing the Soviet path towards the maser from a comparative angle. It identifies, on the one hand, significant differences between the two projects regarding their heuristics, the relationship between theory and experiment, grounding in different academic cultures, and the resulting conceptualization of the maser principle. At the same time, the case also illustrates more fundamental transformations in the practices of postwar research that can be characterized as a convergence between the Soviet and the American science of the period.     

Cathedral of Milan: Structural History of the Load-Bearing System

The structure of the Cathedral of Milan is studied. The features of the building and the original aspects of its load-bearing system are discussed. The progressive development of the structural system is described following its historical phases through four centuries. The final configuration is then analyzed with its main load paths. Detailed information, collected during the 20th century restoration work, was used to determine the geometry and loads. Preliminary analyses are based on equilibrium principles, within the framework of limit analysis for masonry constructions. The main structural restoration works taking place during the life of the Cathedral of Milan are outlined. The results provide a basis for the verification of more detailed numerical analyses and a reference for restoration interventions. Furthermore, the introductory analyses presented here develop the knowledge for future studies devoted to the Cathedral of Milan, encompassing structural, construction, and architectural issues.     

PLACE‐BASED ATTRIBUTES AND SPATIAL EXPENDITURE BEHAVIOR IN TOURISM

In recent discussions on local sustainable development, notions like “local for local” and “home bias” have often played a role. The purpose of this paper is to investigate whether preferences for specific place‐based attributes might constrain or support tourism participation and tourism destination choice of distinct socioeconomic groups of visitors. To test this proposition, a large data set from the Italian Households Budget Survey for the period 1997–2007 has been used and, by means of the double‐hurdle model, tourism participation and expenditure are modeled over the life‐cycle of tourists. These data are next merged with location‐specific attributes including natural amenities and infrastructural and regional‐economic context variables. Our results show that location‐specific or place‐based characteristics affect intra‐ and interregional tourism differently, as well as destination choices. Regional differences between residents in two different macroareas in Italy (North and Center‐South) are investigated. Location‐specific characteristics may be either push or constraint factors for tourism participation. For families living in the North, participation in the tourism market is supported by the tourist characteristics of their home region. For families living in the central and southern regions however, economic conditions of the area where they reside appear to be more significant.     

The transatlantic Muslim diaspora to Latin America in the nineteenth century

Since the 16th century, African Muslims figured prominently among the slave population of the Americas. While the number of Muslims pulled into the trade has always been a matter of speculation, lists of Africans rescued from slave ships provide us with some clues about the size and direction of the Muslim diaspora to Latin America in the 19th century. Based on an analysis of tens of thousands of names recorded in these lists, this essay argues that the majority of Muslim captives leaving Africa departed from Upper Guinea and suggests that Cuba was the center of the forced Muslim diaspora in the Americas. It traces the transatlantic links that connected particular regions of embarkation in Africa to their counterparts in Latin America and considers the implications of those connections for religious and cultural change within 19th-century slave populations. The essay challenges in important ways the colonial/postcolonial divide in Latin American history and uses Islam to pose important questions about the dynamics of social change across slave societies.
