A More Lovingly Made World
From a visit with his children to Makers' Fayre, in New York, the author considers the rise of maker culture and amateur labour in relation to consumption, capitalism and modernity, to provide an afterword to the collection on amateur economies
La proveniencia digital y la obra de arte como derivado
Art is about rarity, about things that are unique and special and cannot be duplicated. Yet the technologies of our time are all about duplication, about copies, about information that is not special at all. At first, it might appear that the traditional form of art is obsolete. If it has value, it is as something from a past way of life, before information technology took over. Yet, what appears to be happening is even stranger. Let us examine some of the special ways in which art as rarity now interacts in novel ways with our abundant sources of information, producing some rather striking opportunities to create value.El arte tiene que ver con la rareza, con cosas que son Ășnicas, especiales y que no pueden ser duplicadas. Pero las tecnologĂas de nuestro tiempo tienen que ver con duplicaciĂłn, copias y con informaciĂłn que no es necesariamente especial. En principio, parecerĂa que la forma tradicional de arte es obsoleta: Si tiene valor es solo como algo de un tiempo pasado, algo perteneciente a un estilo de vida antes de que la tecnologĂa se hiciera cargo. Pero en realidad, lo que sucede es mĂĄs extraño que eso. Revisemos algunas de las formas en que el arte como rareza ahora interactĂșa de maneras novedosas con la abundancia de informaciĂłn, produciendo oportunidades curiosas y llamativas para crear valor
A Multiscale Model of Partial Melts 1: Effective Equations
In this paper a model for partial melts is constructed using two-scale
homogenization theory. While this technique is well known to the mathematics
and materials communities, it is relatively novel to problems in the solid
Earth. This approach begins with a grain scale model of the medium, coarsening
it into a macroscopic one. The emergent model is in good agreement with
previous work, including D. McKenzie's, and serves as verification. This
methodology also yields a series of Stokes problems whose solutions provide
constitutive relations for permeability and viscosity. A numerical
investigation of these relations appears in a companion paper.Comment: 55 pages. Submitted to JGR Solid Eart
A Multiscale Model of Partial Melts 2: Numerical Results
In a companion paper, equations for partially molten media were derived using
two-scale homogenization theory. One advantage of homogenization is that
material properties, such as permeability and viscosity, readily emerge. A
caveat is that the dependence of these parameters upon the microstructure is
not self-evident. In particular, one seeks to relate them to the porosity. In
this paper, we numerically solve ensembles of the cell problems from which
these quantities emerge. Using this data, we estimate relationships between the
parameters and the porosity. In particular, the bulk viscosity appears to be
inversely proportional to the porosity. Finally, we synthesize these numerical
estimates with the models. Our hybrid numerical--analytical model predicts that
the compaction length vanishes with porosity.Comment: 50 pages, submitted to JGR Solid Eart
Garotas de loja, histĂłria social e teoria social [Shop Girls, Social History and Social Theory]
Shop workers, most of them women, have made up a significant proportion of Britainâs labour force since the 1850s but we still know relatively little about their history. This article argues that there has been a systematic neglect of one of the largest sectors of female employment by historians and investigates why this might be. It suggests that this neglect is connected to framings of work that have overlooked the service sector as a whole as well as to a continuing unease with the consumer societyâs transformation of social life. One element of that transformation was the rise of new forms of aesthetic, emotional and sexualised labour. Certain kinds of âshop girlsâ embodied these in spectacular fashion. As a result, they became enduring icons of mass consumption, simultaneously dismissed as passive cultural dupes or punished as powerful agents of cultural destruction. This article interweaves the social history of everyday shop workers with shifting representations of the âshop girlâ, from Victorian music hall parodies, through modernist social theory, to the bizarre bombing of the Biba boutique in London by the Angry Brigade on May Day 1971. It concludes that progressive historians have much to gain by reclaiming these workers and the service economy that they helped create
Les droits disciplinaires des fonctions publiques : « unification », « harmonisation » ou « distanciation ». A propos de la loi du 26 avril 2016 relative à la déontologie et aux droits et obligations des fonctionnaires

A Questionnaire on Materialisms
Recent philosophical tendencies of âActor-Network Theory,â âObject-Oriented Ontology,â and âSpeculative Realismâ have profoundly challenged the centrality of subjectivity in the humanities, and many artists and curators, particularly in the UK, Germany, and the United States, appear deeply influenced by this shift from epistemology to ontology. October editors asked artists, historians, and philosophers invested in these projectsâfrom Graham Harman and Alexander R. Galloway to Armen Avanessian and Patricia FalguiĂšres to Ed Atkins and Amie Siegelâto explore what the rewards and risks of assigning agency to objects may be, and how, or if, such new materialisms can be productive for making and thinking about art today
Measurement of the J/Ï pair production cross-section in pp collisions at TeV
The production cross-section of J/Ï pairs is measured using a data sample of pp collisions collected by the LHCb experiment at a centre-of-mass energy of TeV, corresponding to an integrated luminosity of 279 ±11 pb. The measurement is performed for J/Ï mesons with a transverse momentum of less than 10 GeV/c in the rapidity range 2.0 < y < 4.5. The production cross-section is measured to be 15.2 ± 1.0 ± 0.9 nb. The first uncertainty is statistical, and the second is systematic. The differential cross-sections as functions of several kinematic variables of the J/Ï pair are measured and compared to theoretical predictions.The production cross-section of pairs is measured using a data sample of collisions collected by the LHCb experiment at a centre-of-mass energy of , corresponding to an integrated luminosity of .
