Bodies and everyday practices in designed urban environments

Copyright @ 2010 The Finnish Society for Science and Technology Studies. This article is available open access through the publisher’s website at the link below.In recent years, the centres of many towns and cities have been reshaped by urban design projects, but little attention has been paid to how these transformations are experienced everyday by users of the city. In other words: how do the users of urban centers, such as shoppers, cleaners, or workers, perceive these changes, as embodied subjects in specific material environments? This paper analyses how bodies in two intensely designed urban spaces–the shopping centre of Milton Keynes, a 1960s new town, and Bedford’s recently redeveloped historic town centre–are affected by elements of the built environment. ’Affected’ is a term borrowed from Latour (2004),and the paper works with, and elaborates, some of his and others’ work on how bodies are effectuated by other entities. Such Latourian work pays a great deal of attention to how bodies are affected by both human and non-human entities of many kinds, and we examine how certain aspects of the built environment in these two towns affect bodies in specific ways. However, we also emphasise the variability in this process, in particular that bodies seem unaware–or ambivalently aware–of many entities’ affordances.Economic and Social Research Counci

Becoming the Gothic Archive: From Digital Collection to Digital Humanities

The Gothic Archive is the flagship digital humanities project for the Marquette University library. The project was birthed from a simple digital collection, and through the partnership of faculty and librarians, was transformed into something more. The core tenets of digital collection creation were adhered to in order to create a solid foundation upon which to build the Archive. The expertise of both groups and communication were key in the evolution of the collection, and in discovering and highlighting the relationships between the objects. This case study reviews the steps Marquette took in creating the collection and taking it to the level of digital humanities project

Image recognition with an adiabatic quantum computer I. Mapping to quadratic unconstrained binary optimization

Many artificial intelligence (AI) problems naturally map to NP-hard optimization problems. This has the interesting consequence that enabling human-level capability in machines often requires systems that can handle formally intractable problems. This issue can sometimes (but possibly not always) be resolved by building special-purpose heuristic algorithms, tailored to the problem in question. Because of the continued difficulties in automating certain tasks that are natural for humans, there remains a strong motivation for AI researchers to investigate and apply new algorithms and techniques to hard AI problems. Recently a novel class of relevant algorithms that require quantum mechanical hardware have been proposed. These algorithms, referred to as quantum adiabatic algorithms, represent a new approach to designing both complete and heuristic solvers for NP-hard optimization problems. In this work we describe how to formulate image recognition, which is a canonical NP-hard AI problem, as a Quadratic Unconstrained Binary Optimization (QUBO) problem. The QUBO format corresponds to the input format required for D-Wave superconducting adiabatic quantum computing (AQC) processors.Comment: 7 pages, 3 figure

Murder in Manassas: Mental Illness and Psychological Trauma After the Civil War

Following the American Civil War, the small railroad junction of Manassas, Virginia grew into one of the most prominent towns in the region with the help of town founder William S. Fewell and his family. In 1872, the youngest daughter of the prominent Fewell family was seduced and abducted by Prince Williams County’s Commonwealth Attorney and most prominent orator, James F. Clark without warning. Having just come home from three years of military service in the Civil War, witnessing the death of his twin brother as well as suffering for a year in Elmira Prison as a prisoner of war, Lucien N. Fewell walked into Clark’s jail and murdered his younger sister’s abductor. Acquitted of murder on the terms of mental illness, Lucien Fewell continued to live a life of violence caused by his traumatic experiences during the Civil War. Like many soldiers who came home from the Civil War, Lucien Fewell gives historians an insight into those who came home with combat-induced mental illnesses, as he came back from his military services a changed and violent man

Curvaton Decay by Resonant Production of the Standard Model Higgs

We investigate in detail a model where the curvaton is coupled to the Standard Model higgs. Parametric resonance might be expected to cause a fast decay of the curvaton, so that it would not have time to build up the curvature perturbation. However, we show that this is not the case, and that the resonant decay of the curvaton may be delayed even down to electroweak symmetry breaking. This delay is due to the coupling of the higgs to the thermal background, which is formed by the Standard Model degrees of freedom created from the inflaton decay. We establish the occurrence of the delay by considering the curvaton evolution and the structure of the higgs resonances. We then provide analytical expressions for the delay time, and for the subsequent resonant production of the higgs, which ultimately leads to the curvaton effective decay width. Contrary to expectations, it is possible to obtain the observed curvature perturbation for values of the curvaton-higgs coupling as large as 0.1. Our calculations also apply in the general case of curvaton decay into any non Standard Model species coupled to the thermal background.Comment: 39 pages, 2 figures. v2 matches published version (one reference added
