Availability counts more than quality.
Full details are described in online appendix A. We characterised neighbourhood food resource availability as the count of each type of resource per roadway distance within a 3 km street network buffer, which represents availability to resources relative to the street network and potentially reflects routes of travel.
The assessment included self-reported availability of interventions, a head count of health workers and verification of the condition of the infrastructure and certain utilities.
The model was restricted to the Wadden Sea harbour seal population because of the availability of detailed count data for this population.
Furthermore, the availability of point of care CD4 count testing services could have led to reduction in the proportion of patients LTP at Step 1 of the cascade [ 13].
Environmental influences, for example, can be measured as perceptions of the availability of facilities (individual-level), or an actual count of facilities (area-level).
Line-transect counts in field margins were made to compare habitat availability of patches of farmland and qualities of field margins within the patches.
Blood sample taken for CD4 cell count, availability of CD4 count results, type of ARV prophylaxis for mothers, and additional PMTCT service data were collected for HIV-positive pregnant women and newborns who attended 60 PHCs between April 2007 and March 2008.
By doing this it was expected that the fingolimod exposure ARR relationship would be quantified more precisely given the availability of lymphocyte count data and the presumed relationship between lymphocyte counts and ARR.
Moreover, the availability of spectral count data provides information related to the abundance and proteotypic propensity of peptides, at given charge states, in the context of complex cellular extracts.
With digital publication, it's now theoretically possible to maintain a long tail of book availability, but counting on commercial availability of published items in perpetuity seems risky to me, and if current DRM and copyright battles are won by publishers, even libraries won't be able to keep and lend rare titles in the future.
