Thrust network analysis of masonry helical staircases

We exploit a recent generalization of the Thrust Network Analysis (TNA) to analyse masonry structures of extremely complicated and audacious geometry such as helicoidal staircases. Actually, differently from available methods, based on ad-hoc solutions holding for each particular structure, the TNA allows for studying the equilibrium of structures of arbitrary shape by invoking the principles of limit analysis of masonry structures dictated by Heyman. Four paradigmatic monumental staircases, with increased degree of complexity, have been selected as case studies in order to show the versatility and accuracy of the proposed approach. The results entailed from the generalized TNA are also successfully compared, for the first time in the literature, with those related to the adoption of available analytical methods for the analysis of no-tension membranes.     

Evaluation of Structural Intervention in the Quartel das Esquadras,Almeida (Portugal)

ABSTRACT

The “Quartel das Esquadras” is an 18th century infantry barrack located within the limits of the bulwarked fortress of Almeida, in Portugal. An ongoing adaptive reuse project of the building aims to recover its full capacity and also its importance, by implementing a variety of new uses. The architectural intervention results in the need of the structure to withstand new and diverse imposed loads. As the current configuration of the structure will be altered, the main objective of this article is to evaluate the suitability of some of the proposed structural interventions. The current condition has been characterized following a multidisciplinary approach comprising historical research, visual inspection, non-destructive testing, and structural analysis to identify the possible sources of major structural problems. A portion of the building particularly affected by the alterations has been selected to carry out structural analysis. A comparative safety assessment of the selected area in both current and altered condition has been done through finite element modelling and nonlinear static analysis, resulting in an identification of the weaker points against the new implemented loads and alterations. Finally, proposals for the implementation of the studied intervention, as well as recommendations for future research and analyses, have been given.     

Zopilotes,Alacranes, y Hormigas (Vultures,Scorpions, and Ants): Animal Metaphors as Organizational Politics in a Nicaraguan Garbage Crisis

While scholars frequently frame conflicts over urban waste in terms of a politics of infrastructure, this article frames such conflicts in terms of a politics of organization. In 2008, self‐employed recyclers in and around Managua, Nicaragua blockaded local dumps in an effort to secure rights to scavenge for resellable material. Over the course of this “garbage crisis”, a material and semiotic entanglement of human labor organization with animal ecology became politically salient. At different points, recyclers were compared to ants (hormigas), vultures (zopilotes), and scorpions (alacranes). State officials, NGOs, and recyclers themselves used these animal metaphors to describe the organization of waste collection. Drawing on theories of value from political ecology and economic anthropology, as well as analysis of the deployment of these “organic” metaphors, we outline an “organizational politics” of urban waste.     

Neoliberalisation from the Ground Up: Insurgent Capital,Regional Struggle,and the Assetisation of Land

In this paper we argue that “assetisation” has been a central axis through which both neoliberalisation and financialisation have encroached in the post‐Fordist era. We focus on the mobilisation of land as a financial asset in northwest England's former industrial heartlands, offering an account of how property developer the Peel Group came to dominate the land and port infrastructure of the region through aggressive debt‐led expansion and, in particular, a hostile takeover of the Manchester Ship Canal for its land‐bank. In doing so, we illustrate how the capture of resources, especially land, by private corporations has shaped both substance and process of neoliberalisation from the ground up. By focusing on transformative struggles over land we contribute to research agendas attempting to understand the systemically dispossessive nature of assetisation, its relationship to fictitious capital formation, and the way such neoliberalising transformations are produced through grounded and situated socio‐spatial struggles.     

Report on the pottery from Tell Sufan in Nablus,Palestine

ABSTRACT

This research report aims to give detailed information on the pottery from the 1999 and 2013-16 excavation campaigns taking place at the Tell Sufan site in Nablus, Palestine. These were conducted by the Department of Antiquities at An-Najah National University (ANU) in Nablus. It is of note that this ancient pottery has never previously been the subject of research nor has any literature been published on it. Our methodology consists in: analysing the pottery by identifying it, typifying it, and giving it a function; providing chronological information on the site; comparison of the pottery with that from other sites in Palestine, using archaeological information from the site; and contextualising our findings with other historical and archaeological studies. Examination of the functional use of the pottery allows us to demonstrate human activity at the Tell Sufan site, giving information on the most prosperous phases of occupation in regard to economic aspects, through the late Bronze Age, Iron Age and Byzantine-Early Islamic periods.     

Uneven Urbanisation: Connecting Flows of Water to Flows of Labour and Capital Through Jakarta's Flood Infrastructure

This article analyses processes of uneven urbanisation by looking at flood infrastructure. Combining the conceptual frameworks of uneven development with the political ecology of urbanisation, we use flood infrastructure as a methodological device to trace the processes through which unevenness occurs within, but also far beyond, the city of Jakarta, Indonesia. We do this to show how the development of flood infrastructure in Jakarta is shaped by the logic of capitalism through mutually implicated tendencies of socionatural differentiation and equalisation. These processes render waters, resources and labour as similar across places and times to produce different spaces for different populations, within and beyond city boundaries. This theorisation reveals how the urban inequalities (re)produced by flood infrastructure are intimately linked to inequalities (re)produced through the urbanisation of the non‐city.     

Political Commitment,Policy Ambiguity,and Corporate Environmental Practices

A lack of clear political commitment together with confusing rules and enforcement often characterize the institutional context of policy implementation and regulatory compliance in developing countries. By connecting such contextual features to existing models of policy implementation and regulatory compliance, we examine how regulatory factors are related to basic and proactive corporate environmental management practices in the Pearl River Delta region in China. Drawing on data derived from both a survey and in‐depth interviews, we show that a perception of clear political commitment to environmental protection across multiple government levels and units is positively associated with business efforts in basic environmental practices, regardless of the specific enforcement intensity. Nevertheless, a perception of clear political commitment is not related to proactive environmental practices. Conversely, a perception of policy ambiguity, in the form of confusing regulatory standards and enforcement, is negatively associated with corporate efforts in both basic and proactive environmental practices; yet, intensive inspections mitigate these negative associations with policy ambiguity.     

Primitive Liberals and Pirate Tribes: Black-Flag Radicalism and the Kibbo Kift

ABSTRACT

The Age of Catastrophe (1914–1945) has long been considered a crisis of liberalism. As a political platform and moralistic worldview, the hollowness of liberalism’s promise was exposed when total war struck at the heart of Europe, undermining its presumption of imperial hegemony over much of the world. What emerged in its wake, amid the swells of irremediable nationalisms, is the subject of this article. Blinded by the fog of war and bright lights of modernity, historians often fail to catch the glimpses of alternative aspirations, which escaped the age’s ruptures so as to reinvent and redeem humanity from the depths of its bloody past. Against a backdrop of neglected case studies from Britain and elsewhere – from the Luddites to the Kindred of the Kibbo Kift – this article seeks to show how the spectre of death inspired new ideals of youth and civility that rejected the arrogance of imperial masculinity and industrialised oppression, turning instead to visions of global kinship that were socialist and anarchic, romantic and utopian, primitive and piratical.     

Smells like politics: planning and the inconvenient politics of intensive peri‐urban agriculture

Intensive farming is an increasing part of Australian agriculture, including in the multi‐functional landscapes at the edges of Australian cities. The example of intensive “broiler” poultry production reveals the tensions that arise when sites of hyper‐productivity conflict with social change in rural areas. Planning processes for intensive farming in the Australian state of Victoria are predicated on stability and consensus: on assumed static and uncontroversial ideas of agriculture, its place, and the primacy of agricultural productivity. Yet concerns about the industrialisation of agriculture are live political issues at the local level, especially in dynamic peri‐urban locations. This paper explores the emergence of a politics of place outside the bounds of planning consensus through an analysis of planning appeals and associated media relating to planning permits for intensive poultry developments in Victoria over 2011–2016. We highlight tensions that exist in relation to technical planning assessments and categorisations used to assert farming as the orthodox use of rural land, especially when new forms of farming look and feel demonstrably different. Using Mouffe's problematising of the negation of antagonism and Rancière's notion of the risks of a false consensus democracy, we argue that planning processes for intensive farming illustrate critical issues in participatory planning. While ostensibly post‐political decision‐making narrows the politics of place and food systems to decisions about policing the boundaries and buffer distances placed around intensive poultry developments, alternative representations of rural life persist. The certainty offered by code‐based planning does not negate the ongoing (if inconvenient) politics of intensive peri‐urban agriculture.
