Territorialising Movement Parties: The Case of Nuevo Encuentro in Buenos Aires

How and why do political parties, seemingly focused on electoral politics, also mobilise within contentious arenas? Drawing on qualitative research with a centre-left Argentine party called Nuevo Encuentro (NE) in the city of Buenos Aires this paper demonstrates the importance of a geographical reading of “movement parties” for responding to this question. Specifically, the paper analyses NE’s territorialisation, understood as a strategy for organisation building via the political appropriation of space, typically by opening branches and mobilising activists in neighbourhoods. Between 2007 and 2019 NE’s strategy of territorialisation mobilised across multiple scales—the neighbourhood, city and national—yet in so doing its organisation became overstretched and struggled to engage across both contentious and electoral arenas. Through an analysis of NE’s territorialisation, grounded in the historical and geographical context of contemporary Argentina, the paper provides an original attempt to spatialise the concept of movement party.     

“In Front of the World”: Translating Beatriz Nascimento

This collection translates some of the work of the influential Black Brazilian thinker and activist Beatriz Nascimento (1942–1995) for the first time into English, in collaboration with her only daughter, Bethânia Gomes. Historian, poet, theorist and organiser, Beatriz Nascimento was a key figure in Brazil’s Black Movement until her untimely death in 1995. She dangerously wrote at the height of Brazil’s Military Dictatorship (1964–1985), and theorised extensively on the Black condition in Brazil; the unique experience of Black women; and quilombos—Brazilian maroon societies that she imagined as spaces of both historical and contemporary fugitivity. Following Alex Ratts, this introduction outlines her contribution to radical geography, in particular Black geographies, territoriality and embodiment. It also positions Nascimento within the trans‐Atlantic Black radical tradition. We present two of Nascimento’s essays in translation here. The first, “The Concept of Quilombo and Black Cultural Resistance”, introduces a crucial strand of her scholarly work, on the history and socio‐political significance of quilombos (maroon communities). The second, “For a (New) Existential and Physical Territory”, shows Nascimento in a different mood: philosophical, reflective and iconoclastic. In addition, two of her poems—“Dream” and “Sun and Blue”—are also translated here for the first time.     

MORE THAN MEETS THE FACT: THE UNIVERSALITY OF HISTORY AND THE COLONIAL MEDIATION

This article examines how mediation is not just limited to the format that's selected to convey the findings of previously conducted research that supposedly followed the conventional protocols of the historical discipline. Rather, it considers mediation as a fundamental part of building historical knowledge, for it assumes that every part of the historiographical operation can be defined as “mediation.” Specifically, it deals with colonial historical mediation, a concept that refers to the combination of an overt or concealed agenda, intentional or unnoticed bias, commonsense assumptions, inherited academic and political traditions, conceptual constellations, and more or less informed theoretical beliefs that configure the subtext upon which historical explanation is built, particularly in Latin America.     

A High-Performance Quadrilateral Flat Shell Element for Seismic Collapse Simulation of Tall Buildings and Its Implementation in OpenSees

Shear walls are important lateral force-resistant components of tall buildings. Hence, a reliable numerical model that can accurately represent the mechanical characteristics and large deformations of shear walls is critical for realistic collapse simulation of tall buildings. Based on the theory of generalized conforming element, a high-performance quadrilateral flat shell element, NLDKGQ, accounting for the large deformation using the updated Lagrangian formulation, is proposed herein and implemented in OpenSees. The reliability of NLDKGQ is validated using classical benchmark problems and reinforced concrete specimens. In addition, its capability in simulating the collapse of a tall building is also demonstrated.     

Culture-led urban regeneration policies in the Ibero-American space

ABSTRACT

This article examines cultural policy strategies supporting urban regeneration, focusing on its particular characteristics in the Ibero-American context. We start by developing a systematic contrast between the different circumstances that have led to the emergence of these strategies in the Ibero-American sphere and in other parts of the world. Our examination of the Ibero-American regenerative experience also includes a consideration of the paradigmatic cases that arose initially in the Iberian Peninsula and the typological analysis of subsequent Latin American experiences. The consideration of all these different elements ends up providing a global vision of the specificity of the phenomenon in its Ibero-American context.     

Politics and social violence in developing democracies: Theory and evidence from Brazil

How do the political institutional features of developing democracies influence how violence occurs? Building on research showing that ‘hybrid democracies’ are more prone to social violence, this article argues that elite competition for power in the context of limited institutional oversight plays an important role in explaining violence. The framework here presents possible mechanisms linking subnational political dynamics and rates of social violence in poorly institutionalised contexts. It highlights how political competition, concentrated political power, and constraints on cooperation can create opportunity structures where violence is incentivised and the rule of law is undermined. This is examined empirically using sub-national homicide data from over 5000 Brazilian municipalities between 1997 and 2010. Findings suggest violence is greater in contexts that are highly competitive – where political actors face credible challenges and have a more tenuous grip on power – and those where power is highly concentrated – where political actors have held power for longer periods or face limited credible challenges. Findings also suggest violence varies depending on whether interactions between state and municipal government are likely to be constrained or cooperative; and are consistent with literatures emphasising the importance of structural explanations of social violence. In light of on-going democratic transitions across the globe, the article highlights the value of understanding links between institutional context, contentious politics and social violence.     

Decolonizing travesti space in Buenos Aires: race,sexuality, and sideways relationality

Scholars of space usually neglect the history of travesti populations in Latin America. It is misrepresented not only by disciplinary blind spots but also by global narratives concerned with rehabilitating queer subjects within homonormative projects. Analyzing neoliberal narratives that delink conflicts about racialization and sexuality in Argentina, this article makes room to decolonize the study of travesti experience and embodiment in Buenos Aires's red zone. It examines a network of racialized travestis and their spatial practices, including their migration from the Andean northwest to the sex-work circuits of Buenos Aires. Finally, this article introduces the notion of sideways relationality to account for the cultural and spatial labor that racialized travestis perform at the oppositional margins of homonormative reflexivity.     

DEM Algorithm for Progressive Collapse Simulation of Single-Layer Reticulated Domes under Multi-Support Excitation

In this paper, the Member Discrete Element Method (MDEM) is modified and perfected for three aspects: the algorithm itself, loading and computational efficiency, and to accurately and quantitatively simulate the progressive collapse for large-span spatial steel structures. In addition, the corresponding computational programs are compiled. First, from the perspective of the method, a meshing principle for discrete element models is determined, a treatment for material nonlinearity and strain rate effect is proposed, and a damping model is established. Next, the Displacement Method is introduced to determine the multi-support excitation for the MDEM, and then motion equations of particles under multi-support excitation are derived. On this basis, the specific process of gravitational field loading is presented. Furthermore, parallel implementation strategies for the MDEM based on OpenMP are constructed. Finally, the collapse simulation of a 1/3.5-scaled single-layer reticulated dome shaking table test model under multi-support excitation is carried out. The comparison demonstrates that the ultimate load and failure mode as well as the complete collapse time of the numerical results are consistent with the experimentally measured responses, and the configuration variations from member buckling and local depression until collapse failure are fully captured. Moreover, the displacement time-history curves obtained using MDEM are almost identical to the experimental measurements, and there is a nuance only in the amplitude. It is verified that MDEM is capable of precisely addressing the collapse failure for large-span spatial steel structures. Additionally, the failure mechanism for structures of this type is naturally revealed.     

Onward Precarity,Mobility, and Migration among Latin Americans in London

Contributing to debates around the relationships between precarity, mobilities and migration, this paper examines the nature of precarity among onward Latin American (OLA) migrants as they have moved transnationally to multiple destinations from their homelands to southern Europe and onwards to London across different time periods. Drawing on primary research with over 400 OLAs, the discussion highlights how precarity maps onto onward migration trajectories in fractal rather than linear ways. In moving beyond a continuum approach to labour exploitation, the paper develops the concept of “onward precarity” to capture how migrants negotiate intersecting vulnerabilities in holistic spatio‐temporal ways as they move through different structural contexts across the world from origin, through transition to their final destination country over time. These negotiations are underpinned by multiple agentic tactics that revolve around resilience and reworking strategies as onward migrants traverse wider structures of disadvantage in situ and through mobility in different places.
