The insights in Governing the Commons have provided foundational ideas for commons research in the past 23 years. However, the cases that Elinor Ostrom analyzed have been exposed to new social, economic, and ecological disturbances. What has happened to these cases since the 1980s? We reevaluated one of Ostrom’s case studies, the lobster and groundfishery of Port Lameron, Southwest Nova Scotia ...

Production agriculture such as harvesting in oil palm plantation has been frequently associated with MSD and significant loss of productivities. This study tends to evaluate from the viewpoint of health, the association between self-reported prevalence of musculoskeletal disorders and productivities; the impact of musculoskeletal disorders on productivity. A cross-sectional study was conducted ...

Fishing communities and fisheries governance systems are dynamically engaged in a process of social, ecological, and economic change as they respond to double exposure from globalization and climate change (Leichenko and OBrien, 2008). In this study of the multi-species fishery of Barrington, Nova Scotia, I examine how fish harvesters have responded to warming water temperatures and declining w...

This paper introduces and compares different benchmark parameters for the performance of electromagnetic energy harvesters, including the bottom-up (power according to the harvester model) as well as the top-down view (maximum power that can be generated within a volume) and considering the dependency and scaling of geometrical and physical parameters, such as the mechanical damping. The compar...

Mechanically nonlinear energy harvesters driven by broadband vibrations modeled as white noise are investigated. We derive an upper bound on output power versus load resistance and show that, subject to mild restrictions that we make precise, the upper-bound performance can be obtained by a linear harvester with appropriate stiffness. Despite this, nonlinear harvesters can have implementation-r...
