The Pantheon of Feminist Culture: Women’s Movements and the Organization of Memory

The collective memory of feminist movements, like that of nation-states, is comprised of ‘invented traditions’ and embodied in ‘lieu de mémoire’ (sites of memory). This essay considers national and international examples of collective memory, including International Women’s Day, showing how celebrations of historical events and commemorations of the past were used to cement group cohesion and define boundaries of inclusion and exclusion. The essay proposes a typology of collective memory and examines the implications of the attenuation of memory in contemporary society.     

Chronicle of an early demise,surname extinction in the fifteenth and the seventeenth centuries

It has been amply demonstrated that individuals' reproductive capability is the key explanatory phenomenon for understanding onomastic disappearance during the early modern period. This article analyzes the evolution and consequences of surname extinction in a specific population: Catalonia in the sixteenth and seventeenth centuries. In this article two aspects are examined. First, the observed disappearance of surnames is estimated through historical data collected in the Llibres d'Esposalles (Marriage Books) from 1481 to 1600 at Barcelona Cathedral. Second, the estimated natural extinction of those surnames registered in 1481 is forecast by applying a statistical branching process.     

The brokerage role of supporting organizations inside clusters: how does it work?

The objective of this research is to examine in depth the brokerage roles that supporting institutions play in conducting local business and applying technical knowledge inside clusters. We identify three main roles: a coordination role, characterized by the efforts that organizations play in internally coordinating themselves and establishing a shared institutional framework; an interconnector role, where organizations foster communication along the value chain of the industry; and a gatekeeper role that allows organizations to connect cluster members with external networks. Results obtained in the Toy Valley cluster provide evidence that each kind of supporting organization tends to specialize in specific roles, since universities are best for a coordination role with regard to technical knowledge while private organizations are key for vertical communication and coordination. Similar results were obtained when analysing the extra-cluster contacts that these organizations develop as gatekeepers, as they tend to establish specific communication conduits with similar alters in external networks.     

Intersectionality in feminist geographies

This paper introduces a special themed section that arose from an International Conference on Feminist Geographies and Intersectionality: Places, Identities and Knowledges, held in 2016 at the Universitat Autònoma de Barcelona. Six scholars of Canada, France, Greece, New Zealand, United Kingdom and United States seek to deal in five short papers with the intersectional dynamics of power structures and the central role of place within them. Here we situate the developments of intersectionality in feminist geographies in relation to the role of place and space in constituting intersectional relations, the relevance of context for the development of intersectionality and the use of different methodologies for research on it.     

An Assessment of the Role of an Open Shelter in Reducing Soiling and Microbial Growth on the Archaeological Site of the Bishop’s Palace,Witney, England

Two sets of twelve Portland limestone tablets were attached to carousels outside and under the open, lightweight shelter at Bishop’s Palace (Witney, England) for 18 months to assess the influence of shelters on soiling and microbiological growth on stone. At the start, and at 6-month intervals, tablets were analysed using microscopy (optical and SEM), colour measurement (spectrophotometry), weight change measurement and salt content determination (ion chromatography). Concentrations of NO₂ and SO₂ were also monitored for a month using diffusion tubes. In addition, results were compared with those obtained by the UK National Materials Exposure Programme (NMEP) on chemical weathering rates. Differences in soiling and biological growth on sheltered and unsheltered samples, and their influence on limestone decay were established. The shelter is likely to reduce biological growth by modifying the micro-environmental conditions. However, it may also exacerbate dust deposition, which might increase decay rates in the long-term.     

A Bayesian approach to rapid seismic vulnerability assessment at urban scale

The seismic vulnerability of city centers is commonly assessed by extending the study methods applied to single buildings to urban aggregations. This approach is not always applicable at territorial scale, as it is uneconomical in terms of time and costs. An innovative method provides reasonable large-scale a priori estimation of parameters not directly evaluable from the exterior of buildings by elaborating values which can be measured from the outside. Those parameters are treated as continuous variables, by assigning them a suitable probability density function. The Bayesian approach is adopted, which allows the update of initial hypotheses by using new data gathered during on-site surveys. In this regard, a rapid survey form for the on-site data collection is proposed. An example of its application to a façade of a building structural unit in Santo Stefano di Sessanio in L’Aquila province (Italy) is proposed, showing promising preliminary results for buildings belonging to Italian historical centers.     

The colors of the Fontana di Trevi: an analytical approach

During the last restoration of the Fontana di Trevi -Rome (2014–2015), it has been performed a diagnostic investigation to characterize the materials used to build and obtain the colors of the surfaces of some architectural elements of this fountain. According to the restoration teamwork needs, we focussed our efforts on the dome over the central statue of Oceanus, on the bas-relieves on the sides of the dome, and on the cliff where the water flows. Several samples were collected from these elements and therefore, they were subjected to an analytical approach including infrared spectroscopy, optical and scanning electron microscopy. The achieved results indicated the use of red earth pigments on the dome. The same pigment has been revealed on the bas-relieves, although their colors have an additional contribution due to degraded layers. Samples taken from the cliff showed a complex stratigraphy, although a white scialbo has been identified as original layer, testifying the intentions of the authors in term of color rendering. This information was essential for the restores in order to choose the proper intervention procedure for each investigated surface. The research testified the importance of an integrated diagnostic analysis to preserve the original colours of monuments and building.     

The Influence of Dowel-Bearing Strength in Designing Timber Pegged Timber Joints

ABSTRACT

The employment of timber pegs in timber structure joints is a widespread technology in the field of timber frame building in the United States, where the Timber Frame Engineering Council has published a special Standard to supplement the National Design Specification for Wood Construction. The authors have been studying the possibility of supplementing the Eurocode 5 design formulas, thought for timber joints with metal connectors, with specifications needed for a reliable design when employing timber pegs. The field of application envisaged is that of restoring timber structures and results obtained until now are quite encouraging. In this step of the research, more attention has been paid to deformation process: fir and chestnut samples have been tested to determine their dowel-bearing behavior with steel and ash timber peg while double-shear plane joints made of the same wood species, and fastened with steel as well as timber pegs, have been analyzed.
