Rigging the Pepper Wreck. Part 2—Sails.

Discovered in 1993 at the mouth of the Tagus River, the SJB2 shipwreck—or Pepper Wreck—was tentatively identified as the Portuguese Indiaman Nossa Senhora dos Mártires , lost there on its return voyage from Cochin, in India, on 15 September 1606. Its archaeological excavation led to a tentative reconstruction of the hull, based in contemporary texts on shipbuilding. Further analysis of these texts allowed us to propose a reconstruction of the rigging.

Testing recipes: an experimental approach to paint production processes in Levantine rock art (Spain)

Over more than a century, several proposals have been made on the composition and technical features of the pictorial recipes used by Levantine prehistoric painters. In this paper all these proposals are surveyed and tested through systematic experiments to determine the technical affordance of pigments and binders in different pictorial recipes. Experimental results were then used as independent analytical parameters employed as diagnostic criteria to systematically study an archaeological sample of nine sites located in the Maestrazgo region (Spain) and their surroundings. Results reveal that out of 112 experimental recipes, only 16 afforded the production of paintings technically similar to Levantine rock art.     

Secession of municipalities and economies of scale: Evidence from Brazil

In the 1990s, there was a growing process of administrative decentralization that culminated in the creation of 1,016 new municipalities in Brazil. The aim of this paper is to verify the impact of the municipal secessions on the public expenditures and its association with economies of scale. Based on a Differences‐in‐Differences methodology, the obtained set of evidence indicates that those municipalities that underwent a secession process increased their per capita capital expenditures by 14.7 percent. In addition, we show evidence that strongly suggests that this increase in expenses can be explained by a reduction in economies of scale and rent‐seeking behavior.     

“It is loved and it is defended”: Critical Solidarity Across Race and Place

Since 2010, the Wixárika (Huichol) indigenous people of western Mexico have struggled against transnational mining activity in their sacred pilgrimage site of Wirikuta in the semi‐desertic plateaus of San Luis Potosí. This struggle has been accompanied by a multitude of non‐indigenous and largely urban actors who have joined the Wixárika, bringing with them their own cultural, political and geographic registers for understanding and mobilising against mining in the region. Taking Wirikuta as a contemporary demonstration of interracial and cross‐geographic alliance building, I analyse how social movements that express solidarity and affective ties with the territories and cultures of indigenous peoples struggle to unsettle entrenched racial and spatial relations.     

Moroccan Jewish first-places: contraction,fabrication, dissipation

Abstract

The idea of first places is inevitably linked with diasporas. At the heart of this idea and since the very start, there has always been the Jewish case. The diaspora of the Jews of Morocco, in the periphery, was presented by some authors, as a good case with which to relativize the theoretical pertinence and conceptual inspiration of the Jewish model. Focusing on Jewish history, heritage, and travelling in Morocco, I will continue to question the paradigm of social studies based on the bi-polar center-diaspora model. I will testify to the emergence and fabrication of new Jewish ‘first-places’, a process attending the aging and departure of the last Jews of Morocco and with the support of the Kingdom, while following current, and disruptive trends of contraction, commutation and dissipation of ‘first-places’ in different Jewish practices and narratives. The individualization of religious practice in post-secular societies allows and includes – and often merges – secular, ethnic and political approaches of what once was purely designated as religious identity. Heritage Moroccan landscape (and landscaping) allows different approaches and thus probably why one can think of it as an emerging ‘first-place’ for some.     

In-Situ Destructive Testing of Ancient Strengthened Masonry Vaults

ABSTRCT

Developing suitable tools to assess the actual structural performance and designing and executing interventions to improve that performance is a key issue in the field of conservation and enhancement of architectural heritage. This article presents the results of five full-scale destructive tests performed on the Castello di San Pietro in Verona (North-East Italy), a building set on a hill above the city and going back to the 19th century under the Habsburg Empire. It evaluates the behavior of the barrel vaults of 5.6 m span, 1.1 m rise, and 27 cm thickness in the original building. Although experimental work is common in the relevant literature, the testing program described here was not performed on reconstructed vaults but on original elements, which can reveal their real behavior more clearly. Four strengthening solutions were also evaluated, in which organic and inorganic fibers were applied to both types of matrix.     

Evaluation of Seismic Risk on UNESCO Cultural Heritage sites in Europe

ABSTRACT

Earthquakes have been responsible for the destruction of hundreds of monuments throughout human history. Due to their size, conservation state, and lack of seismic provisions, monuments are particularly vulnerable to the effects of geological hazards. The first step toward the mitigation of the earthquake threat consists of understanding the existing seismic risk and evaluating possible strategies to reduce it. This study presents a simplified assessment to evaluate the probability of damage due to ground shaking on UNESCO World Heritage cultural sites throughout Europe. The seismic hazard model (SHARE) has been employed to derive hazard curves, which were combined with a fragility model to calculate the annual probability of damage or collapse. These calculations were performed assuming different soil conditions, and the resulting risk metrics can be used for risk awareness, to inform the prioritization of the sites in need of structural interventions, and to support additional risk analysis.
