On the Performance of the Subtour Elimination Constraints Approach for the p-Regions Problem: A Computational Study

Geographical analysis - Tue, 06/20/2017 - 09:00

The p-regions is a mixed integer programming (MIP) model for the exhaustive clustering of a set of n geographic areas into p spatially contiguous regions while minimizing measures of intraregional heterogeneity. This is an NP-hard problem that requires a constant research of strategies to increase the size of instances that can be solved using exact optimization techniques. In this article, we explore the benefits of an iterative process that begins by solving the relaxed version of the p-regions that removes the constraints that guarantee the spatial contiguity of the regions. Then, additional constraints are incorporated iteratively to solve spatial discontinuities in the regions. In particular we explore the relationship between the level of spatial autocorrelation of the aggregation variable and the benefits obtained from this iterative process. The results show that high levels of spatial autocorrelation reduce computational times because the spatial patterns tend to create spatially contiguous regions. However, we found that the greatest benefits are obtained in two situations: (1) when ; and (2) when the parameter p is close to the number of clusters in the spatial pattern of the aggregation variable.

Guidelines for Combustible Dust Hazard Analysis


  This book describes how to conduct a Combustible Dust Hazard Analysis (CDHA) for processes handling combustible solids. The book explains how to do a dust hazard analysis by using either an approach based on compliance with existing consensus standards, or by using a risk based approach. Worked examples in the book help the user understand how to do a combustible dust hazards analysis.

The Urban Majority and Provisional Recompositions in Yangon

Antipode A Radical Journal of Geography - Wed, 06/14/2017 - 14:15
Abstract

Yangon is a city where the now predominant modalities of urban transformation arrived late, and after a prolonged period of political repression. As the urban system has been “set loose” to articulate itself to a broader range of inputs and dispositions, many residents attempt to remake long-honed yet fragile mechanisms of social interchange in provisional forms. This ethos and practice of provisionality emphasizes ensemble work aimed at recomposing the character of local district life in various locations across Yangon. Most importantly, it raises questions of how an urban majority—as a confluence of heterogeneous ways of life that has long been critical to making viable urban lives in the postcolony—have endured and can continue to endure in changing circumstances. The article draws from critical black thought as a means of generating heuristic concepts to explore the ways in which residents of several Yangon districts make productive use of the simultaneity of seemingly contradictory inclinations.

The Student's Two Bodies: Civic Engagement and Political Becoming in the Post-Socialist Space

Antipode A Radical Journal of Geography - Wed, 06/14/2017 - 13:55
Abstract

Student activism in Montenegro has remained largely unaccounted for in the growing body of literature on civic engagement and popular politics in the post-Yugoslav space. When students took their discontent to the streets of the Montenegrin capital in November 2011, the dual nature of the student body was rendered visible and audible: while the official student organizations framed their activity as an apolitical expression of discontent over studying conditions, several independent student associations positioned themselves as an extra-parliamentary opposition to the ruling establishment and called for the creation of a wide anti-austerity/anti-corruption coalition. Drawing from critical theory, political sociology, and human geography, this article addresses the questions of why, how, when, and where a part of the student body became political. I argue that a social context that lacks a tradition of politically engaged student movements provides opportunities for a nuanced understanding of political becoming of a hitherto apolitical social group.

Potemkin Revolution: Utopian Jungle Cities of 21st Century Socialism

Antipode A Radical Journal of Geography - Tue, 06/13/2017 - 10:10
Abstract

This paper explores the entanglement of ideology and materiality in the production of the spaces of 21st century socialism. “Millennium Cities” are currently being constructed for indigenous communities throughout the Ecuadorian Amazon, with revenues derived from petroleum extracted within their territories. As iconic spatial symbols of the “Citizens’ Revolution”, the Millennium Cities would appear to embody “the original accumulation of 21st century socialism”—a utopian state ideology promising the collective appropriation of natural resources without the dispossession of the peasantry. Drawing on extensive field research, we argue that they are better understood as a simulation of urban modernity that is symptomatic of the predominance of ground rent in South American capitalism, and which conceals the violent repression of an autonomous indigenous project of petroleum-based modernization. The original accumulation of 21st century socialism can therefore be interpreted as a “fantasy of origins”, which functions to reproduce the primitive accumulation of capital.

Resumen

Este artículo explora la relación entre ideología y materialidad en la producción de los espacios del socialismo del siglo veintiuno. Las “Ciudades del Milenio” están siendo construidas para las comunidades indígenas a lo largo de la Amazonía ecuatoriana, con las regalías procedentes del petróleo extraído en sus territorios. Como símbolos espaciales icónicos de la “Revolución Ciudadana”, las Ciudades del Milenio encarnan “la acumulación originaria del socialismo del siglo veintiuno”–una ideología utópica del estado que promete la apropiación colectiva de los recursos naturales sin la desposesión del campesinado. Mediante un extenso trabajo de campo, argumentamos que son entendidas mejor como una simulación de modernidad urbana, que es sintomática de la predominancia de la renta de la tierra en el capitalismo de Sudamérica, y que oculta la violenta represión de un proyecto indígena autónomo de modernización basada en el petróleo. Por ello, la acumulación originaria del socialismo del siglo veintiuno puede ser interpretada como una “fantasía de orígenes”, que funciona para reproducir la acumulación primitiva de capital.
