For over 20 years J K Gibson‐Graham and the Community Economies Collective have endeavoured to reveal the diversity of economic practice already operative in our so‐called capitalist world. The aim of this paper is to further this ambition by illuminating an occlusion in Gibson‐Graham's own political vision. It argues that diversity, in Gibson‐Graham's thought, is primarily conceptualised as something produced. Drawing upon the work of George Bataille, this paper conceptualises the economy as a superlative and prodigal system of energy exchange that, by definition, is over‐productive and wasteful. In this framing, diversity is not the result of positive relations but emerges from the prolific nature of the general economy. The idea is developed through a discussion of the Detroit urban farming movement. Specifically it argues that the inefficient, redundant and wasteful nature of urban farming is an appropriation of potentialities resident within the general economy. 相似文献

Faced with diminished faculty resources and increased student enrolment from 2010 to 2017, we sought to use blended learning to achieve active learning in a large c.400-student introductory geography class. Working iteratively over seven years and eight classes and using smart classrooms, better timetabling, experimentation with peer review and learning management system (LMS) technologies, as well as the expertise of Queen’s University Continuing and Distance Studies instructional design team to improve integration between course elements, we closely approached the quality of learning achieved in a much smaller enrolment class. It is possible to teach large classes of 400 students in an active and engaged manner. The greatest obstacle to the development and maintenance of this model is institutional culture. 相似文献

Until today, raw material information of copper (Cu) objects is mostly gained from impurities and trace elements and not from the Cu itself. This might be obtained using its stable isotopes. However, isotopic fingerprinting requires the absence of fractionation during the smelting process. The Cu isotope evolution during outdoor smelting experiments with Cu sulphide ore was investigated. It is shown that external materials, in particular furnace lining, clay, manure and sand, alter the isotopic composition of the smelting products. Cu isotopes are fractionated within low viscosity slag derived from matte smelting. The produced metallic Cu has a Cu isotope signature close to the ore. 相似文献

Taking Pre-Raphaelite painter John Everett Millais’s The Rescue (1855) as a case study of shifting aesthetic and moral frameworks, the essay investigates the ways in which mid-century British debates regarding the proper representation of light effects illuminate anxieties about a physically embodied viewer, one who encountered pictures in individualized ways that required regulation and guidance. Represented light, as an element that had a measurable effect on the senses, clearly stimulated a physical response and therefore brought the body to the fore in the art encounter. Types of painting that forcefully engaged the somatic self could become suspect and consequently subject to a process by which they were designated as ‘sensation’, a category in fraught relation with the disappearing ‘sublime’. Combining close visual analysis, a discussion of The Rescue’s novel subject matter, remarks by its first beholders, and nineteenth-century aesthetic theory, the article reflects on the ways in which discourses of art revealed anxieties about the formation of the modern subject and argues that The Rescue is a node in which the death of the sublime meets the birth of sensation. 相似文献
