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.     

Conflictividad capitular y poderes locales en el Cabildo de Manila (1690–1697)

La mayoría de especialistas en la historia de la iglesia de las Filipinas reconocen el gobierno del arzobispo de Manila, fray Felipe Pardo (1677–1689), como uno de los más conflictivos de la historia del archipiélago. Sin embargo, poco o muy poco se ha escrito sobre las actividades políticas y económicas de sus capitulares, particularmente en lo que se refiere a los períodos de sedes vacantes. Frente a la imagen monolítica y triunfante que la historiografía modernista ha proporcionado del discurso tridentino, lo cierto es que hubo grietas, divergencias y conflictos derivados de su confrontación con la realidad local. Los prebendados no constituían un grupo socialmente homogéneo, sino caracterizado por intereses, identidades y lealtades móviles que dependían de contextos políticos y económicos. En este ensayo vamos a analizar las políticas civiles y eclesiásticas de los prebendados del cabildo catedralicio, haciendo especial énfasis en la conflictividad capitular que siguió a la muerte del arzobispo Pardo (1689) hasta finales del siglo XVII.     

Portuguese Blue‐on‐Blue 16th–17th Century Pottery

Blue‐on‐blue (‘berettino’) sherds have appeared in numerous production and consumption archaeological excavations in Lisbon and other archaeological sites in Portugal (dated from the mid‐16th century to the beginning of the 17th century). The abundance of this interesting faience led us to compare it with similar pottery from other well‐known production centres in Italy, namely Liguria (Savona and Albisola), Spain (the Triana kilns) and the Low Countries. Differences in the diffraction patterns of the sherds' pastes from the four countries were observed. In most samples, cobalt blue silicate (cobalt olivine) was identified in the dark blue or light blue glazes through the use of micro‐Raman spectroscopy and diffuse reflectance spectra. A remarkable difference in the calcite contents of the Lisbon and Seville pottery sherds was observed, in accordance with previous observations of high calcite contents of Seville ceramics. A comparison was also made for all of the blue‐on‐blue sherds studied here with many other 16th–17th century sherds from Lisbon using bivariate plots of K/Si versus Ca/Si. Lisbon and Seville pottery behave very differently, whereas sherds from Italy and the Low Countries occupy intermediate positions.     

Microstoria,Pacific History,and the Question of Scale: Two or Three Things That We Should Know About Them

This article is prompted by the recent debate on the so-called crisis in the humanities, and the related call for historians to change direction by returning to history of the longue durée. While pointing out that the ‘crisis’ is more influenced by the changing political economy of the tertiary education sector than by specific historiographical practices, I suggest that small-scale analysis remains compatible with global history approaches. Articulating a parallel examination of Pacific historiography and the Italian variant of microhistory, the article argues that the latter provides fertile stimuli for Pacific history. In particular, I maintain that integrating social analysis can serve to counterbalance the over-emphasis on cultural aspects found in much Pacific historiography.     

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.     

Going Against the Grain: Why Do Canada and the United States Market Wheat So Differently?

At the turn of the twentieth century, private grain exchanges settled the daily prices for North American wheat. By the end of the Second World War, the Canadian and US governments had intervened significantly in these markets. The Canadian government required farmers in its western provinces to deliver their product to the Canadian Wheat Board (CWB), a single-selling-desk agency that, by then, had supplanted private wheat marketing in western Canada. Meanwhile, the United States government subsidized farm incomes with domestic-use taxes and import tariffs, but otherwise preserved private wheat marketing. In this article, I demonstrate that these disparate agricultural policies were broadly defined by immutable economic realities imposed on each country by global wheat-trade patterns and triggered by unprecedentedly severe agricultural crises. That is, amidst the precipitous fall in wheat prices in the early 1930s, each government crafted farm-support policies that reflected its domestic-consumption share of wheat production and the importance of wheat to its overall economy.
