Industrial relations stress and job satisfaction: Concurrent effects and mediation

We examine the effects of negative and positive industrial relations stress on both mood (negative and positive) and job satisfaction. Twenty industrial relations practitioners completed daily reports of industrial relations stress, mood, and job satisfaction over a 20-day period. After controlling for serial correlation, negative industrial relations stress affected negative mood and, in turn, job satisfaction. Positive industrial relations stress had direct effects on both positive mood and job satisfaction with positive mood also affecting job satisfaction. All effects were concurrent with no next-day effects of stress on mood or job satisfaction. Further research on industrial relations stress is both warranted and encouraged.

High-level techno-economic assessment of negative emissions technologies

This paper presents results from research conducted to provide a high level techno-economic and performance assessments of various emerging technologies for capturing CO₂ from the air, directly and indirectly, on a life-cycle basis. The technologies assessed include ‘artificial trees’, the soda lime process, augmented ocean disposal, biochar and bio-energy with carbon capture and storage.These technologies are subjected to quantitative and qualitative analyses, based on the most recent peer reviewed data in the literature, to identify their potential performance as well as the technical and non-technical barriers to their adoption and scale up. Key findings for each technology are presented which seek to highlight the state of technological development and research needs, the anticipated life cycle capture cost in $/tCO₂ based on their potential to deliver a 0.1 ppm CO₂ reduction per annum, policy requirements for scale up and, in light of these findings, the likely role that they will play in addressing climate change and broader environmental issues in the medium to long term.The key finding from the work is that the degree of scale-up required for negative emissions technologies to have a material impact on atmospheric emissions (i.e. at a ppm level) is probably unrealistic in less than 20 years. Therefore, emissions prevention efforts should remain the main focus in addressing climate change and the likely role for negative emissions technologies will be in augmenting a suite of mitigation measures targeting economically or practically difficult emissions.

Circuit-theory applications to connectivity science and conservation

Conservation practitioners have long recognized ecological connectivity as a global priority for preserving biodiversity and ecosystem function. In the early years of conservation science, ecologists extended principles of island biogeography to assess connectivity based on source patch proximity and other metrics derived from binary maps of habitat. From 2006 to 2008, the late Brad McRae introduced circuit theory as an alternative approach to model gene flow and the dispersal or movement routes of organisms. He posited concepts and metrics from electrical circuit theory as a robust way to quantify movement across multiple possible paths in a landscape, not just a single least-cost path or corridor. Circuit theory offers many theoretical, conceptual, and practical linkages to conservation science. We reviewed 459 recent studies citing circuit theory or the open-source software Circuitscape. We focused on applications of circuit theory to the science and practice of connectivity conservation, including topics in landscape and population genetics, movement and dispersal paths of organisms, anthropogenic barriers to connectivity, fire behavior, water flow, and ecosystem services. Circuit theory is likely to have an effect on conservation science and practitioners through improved insights into landscape dynamics, animal movement, and habitat-use studies and through the development of new software tools for data analysis and visualization. The influence of circuit theory on conservation comes from the theoretical basis and elegance of the approach and the powerful collaborations and active user community that have emerged. Circuit theory provides a springboard for ecological understanding and will remain an important conservation tool for researchers and practitioners around the globe.
