Analysis of Heavy Metals in Smoke Deposits in the Limewash of the Royal Artillery Factory of Seville (17th Century): Contributions to the Location of the Furnaces

The Royal Artillery Factory of Seville in Spain originated from pre‐existing private bronze foundries dating from the 16th century. The paper analyses the stratigraphy of wall cladding in the areas traditionally known as the ‘Old Foundry’ and the ‘New Foundry’, through its characterization by optical microscopy, scanning electron microscopy with energy‐dispersive X‐ray spectrometry (SEM‐EDX), micro‐X‐ray fluorescence (μ‐XRF) and micro‐X‐ray diffraction (μ‐XRD), in order to analyse the metal deposits that have accumulated since the 17th century. The data obtained allowed the verification of the available historiographical information and the location of the original bronze smelting furnaces. The analysis of patinas deposited on the overlapping layers of lime also confirmed that neither the raw materials nor the composition of the alloys used presented any substantial changes.     

ET SI C'ÉTAIT PAR LA FIN QUE TOUT COMMENÇAIT? PEN BEFORE PLOT,OR TRESCH ON POE'S REVERSALS

This brief comment offers some reflections on John Tresch's “Compositor's Reversal.” Contrasting his approach with Gaston Bachelard's, I situate Tresch in the tradition of reading Edgar A. Poe's Narrative of Arthur Gordon Pym as a riddle to be decoded. I suggest that Tresch's analytical emphasis on material composition practices rather than Pym's content opens up insightful ways of reading both Pym itself in terms of its composition, style, and narrative voice, and also Poe's well‐known programmatic Philosophy of Composition. The key achievement of Tresch's article beyond its engagement with Poe scholarship is its contribution to the study of writing practices and media studies more broadly. By demonstrating the tight connection Poe forged between natural theology and the material practice of typography, Tresch inserts the typesetting process as an important step in the historiographical trajectory between pen and typewriter. He shows that the mid‐nineteenth‐century context of natural theology marks a decisive difference in connotation between Poe's compositional play with questions of authorship and plausibility, of truth and appearance both described in and performed by his narrative, and later concerns with the apparatus and its potential for the production of an écriture automatique.     

The Pluralities of Black Geographies

This paper seeks to spur conversations around the inherent pluralities found within Black Geographies. While analyses of Black Geographies have provided important reflections on the spatial imaginaries and practices of Black populations, less attention has been paid to the differences found among Black geographical expressions. This piece therefore seeks to draw out the ways in which Black people uniquely conceive of space by highlighting the distinctions present within different Black social movements. The authors explore the spatial politics of the Universal Negro Improvement Association, the Black Panther Party for Self‐Defense, and the Provisional Government of the Republic of New Afrika to argue that while these three movements all attempted to create spaces of Black self‐determination, they did so with distinct spatial aspirations and concrete politics. The authors argue that recognising and accounting for the pluralities of Black spatial creation is necessary for realising more just geographies.     

Inside Checkpoint 300: Checkpoint Regimes as Spatial Political Technologies in the Occupied Palestinian Territories

As a part of the architecture of the Israeli occupation of the Palestinian Territories, the Israeli government introduced in 2005 a series of so‐called terminal checkpoints as “neutral border crossings”, to minimise the impact of these barriers on Palestinian lives through a different design and the use of several machines, such as turnstiles and metal detectors. In this article, we analyse terminal Checkpoint 300 in Bethlehem, framing it as a spatial political technology aimed at controlling the movement of Palestinians. More specifically, we investigate the interactions between Palestinian commuters, Israeli soldiers/security guards and the machines operating inside Checkpoint 300. We conclude by suggesting that Checkpoint 300 is a porous barrier whose regime is produced, reproduced but also challenged by such interactions, and that, despite the new “neutral design”, Checkpoint 300 is a place still filled with tension and violence, often exercised by the machines and their “decisions”.     

Disability Consciousness on the Frontlines of Urban Struggle

Drug wars, austerity and gentrification are interwoven social relations in many North American urban centres and are typically met with organising of varying degrees of militancy. Loïc Wacquant characterises many of these sites as highly stigmatised, associated with violence and pathology. In Toronto's downtown east end (DEE), one such stigmatised urban space, disabled activists are far from unfortunate casualties. They tend to refer to the DEE as an “urban battleground”, where disabled people politicise and challenge the DEE's pathology and stigma by linking into emerging radical disability politics across the global North and by developing localised revolutionary disability consciousness. Drawing on oral stories, zines and blogs of disabled activists and workers in Toronto's DEE, this article uses Rachel Gorman's dialectic of disability/disablement to analyse the emergence of revolutionary disability consciousness and the centrality of disabled people on the frontlines of anti‐gentrification and harm reduction organising in Toronto's DEE.     

FROM LEFT‐WING TO COMMUNIST MELANCHOLY: TRAVERSO'S WAGER

Enzo Traverso's inspired book Left‐Wing Melancholia revisits iconic representations of revolutionary hopes and defeats not to draw up an inventory of what has been lost but rather to remind his readers that past defeats also contain the traces of unfulfilled possibilities. After the end of the Soviet Union and the global triumph of neoliberal capitalism, the communist utopian imagination of a classless society, Traverso suggests, can be reignited through memorial practices of resilient, resistant melancholy. Traverso's argument draws on Walter Benjamin's notions of materialist history, redemptive memory, and knowing melancholy. Yet the nameless vanquished masses to whom Benjamin's concept of history seeks to do justice remain marginal in Traverso's book. Instead, revolutionary defeat is cast in the tragic mold of succeeding by failing, a trope exemplified by figures such as Auguste Blanqui, Charles Péguy, or Daniel Bensaïd. In response to Traverso's reliance on the transhistorical category of the tragic, this essay argues for a more abstractly theoretical understanding of left‐wing melancholy as conditioned by historically specific class relations that constrain and challenge the engaged intellectual. Moreover, this essay questions Traverso's dualistic treatment of politically committed (Benjamin, Brecht, C. L. R. James) and elitist intellectuals (Adorno) and concludes that the concept of left‐wing melancholy must ultimately be interrogated against the backdrop of a lingering uncertainty about the relationship between theory and praxis that, as Adorno claims, one can already find in Karl Marx—an uncertainty that is hence inscribed into the history of any Marxist theory of revolution and history.     

The Making of Tupaia’s Map: A Story of the Extent and Mastery of Polynesian Navigation,Competing Systems of Wayfinding on James Cook’s Endeavour,and the Invention of an Ingenious Cartographic System

Tupaia’s Map is one of the most famous and enigmatic artefacts to emerge from the early encounters between Europeans and Pacific Islanders. It was drawn by Tupaia, an arioi priest, chiefly advisor and master navigator from Ra‘iātea in the Leeward Society Islands in collaboration with various members of the crew of James Cook’s Endeavour, in two distinct moments of mapmaking and three draft stages between August 1769 and February 1770. To this day, the identity of many islands on the chart, and the logic of their arrangement have posed a riddle to researchers. Drawing in part on archival material hitherto overlooked, in this long essay we propose a new understanding of the chart’s cartographic logic, offer a detailed reconstruction of its genesis, and thus for the first time present a comprehensive reading of Tupaia’s Map. The chart not only underscores the extent and mastery of Polynesian navigation, it is also a remarkable feat of translation between two very different wayfinding systems and their respective representational models.     

EXTENDED MEANING AND UNDERSTANDING IN THE HISTORY OF IDEAS

Many historians focus primarily on authors' “intended meanings.” Yet all textual interpreters, including historians, need a second kind of meaning. I call this idea “extended meaning,” a new name for an old idea: “P means Q” is the same as “P logically implies Q.” Extended and intended meaning involve different kinds of understanding: even if we grasp exactly what authors meant, we miss something important if we overlook their errors, for example. Crucially, extended and intended meaning are not alternatives: just as some parts of texts cannot be understood without historical analysis, so too some parts of texts cannot be understood without philosophical analysis. Indeed, some historians are adept at using extended meanings to recover intended meanings. But the failure to make this explicit has led many historians to undervalue philosophical analysis. This article thus applies the idea of extended meaning to three practical questions: whether we can deviate from authors' intended meanings, whether we can use anachronisms, and how we can use extended meanings to recover intended meanings. The idea of extended meaning thus strengthens our theoretical foundations and offers valuable practical tools.     

Yoshikatsu Sugiura's Contribution to the Development of Quantum Physics in Japan

Previous research in the history of physics has led us to believe that Yoshio Nishina (1890–1951) virtually single‐handedly imported quantum physics into Japan. However, there are first‐hand accounts that Yoshikatsu Sugiura (1895–1960) also played an important role. Sugiura made his name in quantum chemistry with his contribution to the Heitler‐London theory of the chemical bond. Yet, historians of physics have paid scant attention to him. This paper brings forward information on Sugiura from his letters, his scientific papers, and his own recollections until ca. 1930. By examining this material, the present paper studies Sugiura's accomplishments in Europe and his contributions to the development of quantum physics in Japan. We conclude that Sugiura was one of the most important physicists when it comes to the arrival of quantum physics in Japan. In addition, we assess why he has been under‐appreciated in the history of physics in Japan. Our historical study on Sugiura suggests that, in addition to the position Nishina and his students rightfully occupy, there still are important unexplored aspects in the history of Japanese quantum physics.     

The Impact of Forum Interdependence and Network Structure on Actor Performance in Complex Governance Systems

One of the main assumptions of the Ecology of Games Framework (EGF) is that governance processes are heavily affected by the interactions among policy actors that take place in multiple decision‐making forums, which often function interdependently. In this article, we use data collected in the Tampa Bay and California Delta water governance systems to examine how “biophysical interdependence”—the extent to which forums deal with interconnected policy problems—impacts the costs that actors face when they participate in forums, which in turn can affect their performance in them. Furthermore, we examine how the individual information exchange networks that actors have (i.e., their ego‐networks) can mediate the previous relationship. We find that actors with networks that have more closure are better able to mitigate the costs associated with participating in biophysically interdependent forums, thus leading to better in‐forum performance. Our findings shed new light on the relationship between structure and function in complex ecologies of games.
