Blind Spots: Electronics Firms, and the Social and Environmental Harms of the Electronics Commodity Chain
by Lucy McAllister, Environmental Studies, University of Colorado
Abstract: The global electronics commodity chain perpetuates widespread human and environmental harms, including the global sale of 'conflict minerals' that are used to fund the violence of warlords (Spectrum 2011), the depletion of virgin minerals and precious metals, primarily, from Africa (Boone & Ganeshan 2012), the persistence of unsafe and environmentally hazardous working conditions at electronics factories in Asia (Zhou 2013), and the abridgement of electronics workers' rights to unionize (Cheng et al. 2012). The practices commonly used to recycle electronic waste (e-waste) in the informal sector of developing countries, where roughly 50-80% of the global hazardous e-waste stream is sent, also produce severe harms, including health risks especially for women and children (Frazzoli 2010).
Despite the lead role that multinational electronics firms' likely play in the social and environmental harms of the electronics commodity chain, little research has been done on these issues. The aim of this project is thus to investigate how the specific role of lead firms in producing severe human and environmental problems throughout the electronics commodity chain has gone largely unnoticed by external audiences. Using impression management theory, I will ask whether or how electronics firms use impression management mechanisms to shift attention away from their detrimental business practices, thereby legitimizing themselves in the eyes of the public, and making it easier to sell their products and accumulate capital.
Biography: Before coming to study at the University of Colorado, Boulder, Lucy McAllister graduated summa cum laude from Connecticut College in 2009 with a B.A. in Environmental Studies and German Studies. After college, Lucy spent time in Hamburg, Germany on a Fulbright scholarship and, later, worked at the German Consulate in Chicago, Illinois. Lucy completed her M.S. in environmental studies at CU in May 2013, and has continued within the environmental studies program to pursue a PhD.
Broadly, Lucy explores the business-society-environment relationship, focusing on the role of lead firms in the human and environmental harms of the electronics commodity chain. She was the 2012 Theory in Critical Political Ecology Paper Competition Winner at the University of Kentucky's Dimensions of Political Ecology Conference, and, in the fall of 2013, Lucy was awarded a CIRES Graduate Research Fellowship. Lucy's first article, 'Women, E-waste & Technological Solutions to Climate Change,' was recently published by the Health and Human Rights Journal in June 2014.

Uncovering the structure and dynamics of a single nanoparticle using the world's shortest laser pulses
Dan Hickstein - Kapteyn-Murnane Group, JILA - University of Colorado
Modern femtosecond lasers can produce pulses of light that are shorter than the vibrational periods in molecules and generate electric fields stronger than the Coulomb field that binds electrons in atoms. These lasers are ideally suited to studying ultrafast processes in nanomaterials, such as electron transfer in photovoltaic nanostructures. However, all previous laser-nanoparticle experiments have been conducted on nanoparticles suspended in solvent, embedded in a bulk material, or attached to a surface, meaning that powerful gas-phase spectroscopy techniques cannot be used. In 2011 we embarked on a collaboration with the Jimenez group to construct a photoelectron–photoion spectrometer capable of examining isolated nanoparticles in the 'gas phase.' To our surprise, the completed spectrometer was capable of recording the complete photoion distribution resulting from the interaction of a single nanoparticle with the femtosecond laser pulse. This breakthrough technique has allowed for the examination of localized light fields in nanostructures, the discovery of shock waves in nanoscale plasmas, and the observation of the evanescent wavefunction in quantum dots. In this talk I describe how we combined the tools of physical chemistry, laser physics, and atmospheric science to construct this new instrument, describe the discoveries to-date, and discuss our plans for future experiments, which include pushing the time-resolution towards the attosecond frontier.
