However, we excluded experiments that occurred in timber plantations because these sites might have unnaturally depauperate understories due to herbicide treatments or other artefacts of timber management (e.g. disking, mechanical shrub removal, monotypic canopy structure and composition).
Our paper seeks to contribute to existing understanding of the unexpected and collateral effects of the liberalisation process in the power system by examining a natural experiment that occurred in Spain in 2009.
The "natural experiment" that occurred in Poland now requires further support from evidence based policy interventions.
All patients used the web-chat facility for the attention and safety behaviours experiment that occurred early in therapy, and 55% used the facility on at least one other occasion.
The natural experiment that occurred in the UK with the pH1N1 introduction, where presentation bias was estimated through additional studies and presentation was known to be too high in the summer months and too low in the winter months of 2009, provided an opportunity to test the ability for the hospital staff-ILA system to predict burden of disease.
We took advantage of the natural experiment that occurred during the 2008 Beijing Summer Olympics, where the Chinese government successfully reduced and restricted air pollution emissions in Beijing and the surrounding province, resulting in 20 60% reductions in most pollutants (Rich et al. 2012; Zhang et al. 2013).
Other symbols are experimental results obtained by rotary shear experiments on sediments that occur around faults in the Nankai Trough (Expedition 316; Sites C0004D and C0007D), from Ujiie and Tsutsumi (2010), Tsutsumi et al. (2011), and Hirose et al. (2008), shown for comparison.
We next demonstrate on our experimental data set that the empirical Bayes method removes batch effects that occur between experiments.
DOI: http://dx.doi.org/10.7554/eLife.09262.010 In earlier experiments homeostatic synaptic scaling that occurs after blockade of resting NMDA receptor activity was shown to rely on protein synthesis, in particular synthesis of new AMPARs rather than the insertion of existing ones (Sutton et al., 2006, 2007).
