Constructing commons in the cultural environment
This Article sets out a framework for investigating sharing and resource-pooling arrangements for information- and knowledge-based works. We argue that adapting the approach pioneered by Elinor Ostrom and her collaborators to commons arrangements in the natural environment provides a template for examining the construction of commons in the cultural environment. The approach promises to lead to a better understanding of how participants in commons and pooling arrangements structure their interactions in relation to the environments in which they are embedded, in relation to information and knowledge resources that they produce and use, and in relation to one another
The Relationship Between GPS Sampling Interval and Estimated Daily Travel Distances in Chacma Baboons (Papio ursinus)
Modern studies of animal movement use the Global Positioning System (GPS) to estimate animalsâ distance traveled. The temporal resolution of GPS fixes recorded should match those of the behavior of interest; otherwise estimates are likely to be inappropriate. Here, we investigate how different GPS sampling intervals affect estimated daily travel distances for wild chacma baboons (Papio ursinus). By subsampling GPS data collected at one fix per second for 143 daily travel distances (12 baboons over 11â12 days), we found that less frequent GPS fixes result in smaller estimated travel distances. Moving from a GPS frequency of one fix every second to one fix every 30 s resulted in a 33% reduction in estimated daily travel distance, while using hourly GPS fixes resulted in a 66% reduction. We then use the relationship we find between estimated travel distance and GPS sampling interval to recalculate published baboon daily travel distances and find that accounting for the predicted effect of sampling interval does not affect conclusions of previous comparative analyses. However, if short-interval or continuous GPS dataâwhich are becoming more common in studies of primate movement ecologyâare compared with historical (longer interval) GPS data in future work, controlling for sampling interval is necessary
