The eco-frontier paradigm: rethinking the links between space, nature and politics

Accepted for publication in GEOPOLITICSInternational audienceThere is a gap in the geographical/geopolitical literature about the process that motivates humans to conquer a boundless, timeless and invaluable wilderness in the name of plural ecologies to serve their own political interests in control and territory building by means of ‘green gerrymandering'. The ecological frontier (or eco-frontier), a neologism produced by a contemporary greened civil society, can be considered a new paradigm that embraces the mental representations and spatial constructions of eco-conquest without restricting its temporal dimension to the present time. Indeed, the eco-frontier is a genealogical paradigm where new dynamics always revisit old processes. The creation and use of the eco-frontier can illuminate the history of the global territorialisation of nature in the last three centuries. From a spatial point of view, two main understandings of the eco-frontier exist. The first characterises virtual and mental imageries of natural spaces of eco-conquest that are strongly associated with Westernised representations of nature. The second considers eco-frontiers as geographical processes to understand the green dynamics of territorial appropriation and re-conquest. As a genealogical paradigm, the eco-frontier has a specific temporal dynamic that integrates the different historical contexts and political ideologies of nature. Three generations of eco-frontiers (Empire, Geopolitical and Global generations) began at different times and co-exist today, with superposition and percolation. This empirical study shows how contemporary environmentalists and green stakeholders produce specific discourses and representations on global eco-frontiers. The paper focuses on the current territorial domination carried out by contemporary eco-conquerors creating possible new geopolitics

Performance: Its meaning and content for today's business research

Changes may have been made to this work since it was submitted for publication. A definitive version was subsequently published in Computers in Industry (2007), DOI: 10.1016/j.compind.2007.05.002Performance, as a concept, is a subject open to wide variability as it is a somewhat imprecise word when it functions as a placeholder in research. By using definitions from the Oxford English Dictionary and other research disciplines, this paper provides a wide-ranging discussion of the meaning and content of the term performance in the business performance research. The paper reviews numerous characteristics of performance, such as its being a subjective entity that is non-random in character; while it is governed by its relevance to a particular environment, and operates from a particular objective, by virtue of a set of chosen characteristics. It contains elements that are both static and dynamic; and it is possible to characterise via three states: unformed or random, formalised or systematic, and deformed or over-bureaucratic. Also, an encapsulating model of performance, whereby performance acts as a frame around performance management, performance assessment and performance measurement is proposed. Studies of performance as a concept in itself are practically non-existent in the business research; the value of this paper, therefore, lies in its attempt to explicate previously undocumented models of performance

Evaluating Identification and Sorting Technologies for Improved Ferrous and Non-Ferrous Recycling

Metals recycling is one of the oldest industries in the United States that now employs over 530,000 individuals. It has always played a significant role in the economy, contributing $109.78 billion to the US economy in 2018. Furthermore, recycling supplies extensive goods and services, the Institute of Scrap Recycling Industries (ISRI) reported that every year greater than 900M Mt of scrap (~2 billion pounds) are consumed by manufactures globally, equating to 40% of the raw material demand. Additionally, as climate change becomes a greater threat, we must seek practices to lessen our carbon footprint, and recycling helps to reduce the environmental impact of metal production. Relying on this industry as an alternative to make-take-waste habits means understanding how the industry’s efficiency is being challenged by growing feed volumes of diverse, complex product designs. This work details the internal and external factors that impact the development of ferrous and nonferrous recycling operations. This knowledge is then applied to design and perform an extensive “true to yard” analysis with technologies that have potential for addressing inbound inspection and material identification challenges. These results allowed us to understand the limitations that would arise when attempting their deployment at material handling facilities, and then use these factors to build a model capable of quantifying and comparing these techniques, which is not available in previous literature. Inbound inspection and material identification are critical; they are the first opportunity once material is received to prevent comingling, downcycling, and contamination. Scrap yards identify and sort specific alloys from large quantities of mixed metals by means of visual and cognitive recognition with the aid of a few standard tools (a magnet, file, acids, and/or grinding wheel). This work tested handheld analyzers (HHs) that utilize x-ray fluorescence (XRF) and laser induced breakdown spectroscopy (LIBS) technology to determine the level of technological assistance they can provide to improving identification during the inspection process. Beforehand, we had a good indication of how HHs perform on material that has clean, smooth, uncoated surfaces (prompt scrap) but, what we aim to find is their response when used on “unprepared materials,” like those coming out of stock that are old, used, weathered, and/or warped (obsolete scrap). For these instruments to be deemed useful for inbound inspection/ identification purposes, it is crucial to understand and evaluate their limitations on scrap that is not altered and thus, true to a yard setting. Results indicate that in their current state, HHs can inform and verify content for a significant range of materials. They also show grade matching (identification of an alloy by name) is possible but less likely on unprepared scrap. However, the ability to register and share elemental composition percentages at rapid speeds, allows a trained user to know immediately what contaminants are present, often being high levels of Si and Fe. In addition to understanding how these technologies perform under real world conditions, it is also important to quantify whether their benefits outweigh their costs. This work examined five different scenarios for sorting and identification, each scenario offering different levels of alloy-specific sorting capabilities. The model that was created allowed for return on investment (ROI) comparisons, and evaluated the impacts of different market conditions, changes in volume, volume distribution, and uncertainty. This technoeconomic assessment showed that even a high amount of comingled material can be profitable at high volumes under certain market conditions. Although, comingling led to diminished profits, where segregating proved beneficial even at lower volumes. As we continue to invest, educate, and execute sustainable practices, we must understand that recycling should only come as an attempt after we have exhausted our efforts to reduce and reuse. Moreover, we can work to obtain a better balance along the supply chain by encouraging and creating more practices like design for recycling (DfR) and extended producer responsibility. Being that these behaviors will require a lot of societal reform, we need to ensure that we work to reduce landfill feed by providing the recycling industry with the tools and practices that are effective and efficient at getting materials identified and sorted

Beyond Rio+20: governance for a green economy

This repository item contains a single issue of the Pardee Center Task Force Reports, a publication series that began publishing in 2009 by the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future.As an intellectual contribution to the preparations for the 2012 United Nations Conference on Sustainable Development (UNCSD, a.k.a. Rio +20), the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future convened a task force of experts to discuss the role of institutions in the actualization of a green economy in the context of sustainable development. A stellar group of experts from academia, government and civil society convened at the Pardee Center and were asked to outline ideas about what the world has learned about institutions for sustainable development from the past, and what we can propose about the governance challenges and opportunities for the continuous development of a green economy in the future. The Task Force members were encouraged to think big and think bold. They were asked to be innovative in their ideas, and maybe even a little irreverent and provocative. They were charged specifically NOT to come to consensus about specific recommendations, but to present a variety and diversity of views. This report presents their thoughts and ideas

Crossed Glances on the Perception of Consumer Competencies within the Energy Sector: The Case of a French Energy Supplier

This paper discusses the concept of “consumption competence” at the heart of Service-Dominant Logic and the co-creation process of value. In order to examine the issues related to this emerging concept, the research methodology was divided in two parts. In the first one, we introduced a longitudinal ethnography research (2005-2007) based on participant observation and in-depth interviews with employees in a French business energy supplier called “Utility X”. This choice was the best means to understand how do managers in the energy sector consider their customers: are clients represented as active actors or as passive actors within their own consumption experiences. The second part of this research based on in-depth interviews conducted in 2009, involved a group of 10 customers of “Utility X”. The objective of these interviews was to emphasize the consumer's activation of his competencies in the energy sector. This methodology was applied in order to get crossed glances on the concept of the “consumption competencies” emerging in the energy sector.Competence, energy sector, company representation, consumer education, operant resources

Bridging lab and industry with flow electrochemistry

A revitalization of organic electrosynthesis has incited the organic chemistry community to adopt electrochemistry as a green and cost-efficient method for activating small molecules to replace highly toxic and expensive redox chemicals. However, many of the critical challenges of batch electrosynthesis, especially for organic synthesis, still remain. The combination of continuous flow technology and electrochemistry is a potent means to enable industry to implement large scale electrosynthesis. Indeed, flow electrosynthesis helps overcome problems that mainly arise from macro batch electro-organic systems, such as mass transfer, ohmic drop, and selectivity, but this is still far from being a flawless and generic applicable process. As a result, a notable increase in research on methodology and hardware sophistication has emerged, and many hitherto uncharted chemistries have been achieved. To better help the commercialization of wide-scale electrification of organic synthesis, we highlight in this perspective the advances made in large-scale flow electrosynthesis and its future trajectory while pointing out the main challenges and key improvements of current methodologies
