The multiplicity of data collection efforts that are unaligned, duplicative, burdensome and expensive is harming progress towards reaching sustainable development.
We adopt definitions from set theory, where the term set is used when each element in the set is distinct, and the term collection is used when the multiplicity of each element is important.
Examples include characteristics of the study population, selection of participants, procedures and measures used in data collection, length of follow-up, unaccounted multiplicity of analyses, and missing data.
The multiplicity and secretiveness of smuggling routes also muddies data collection, which must be compiled from numerous places, and it seriously hinders the ability to release confiscated animals back into the wild.
In order to deal with the wide variety of potential substrates, a multiplicity of GSH transferases exists each tissue having its own collection and each enzyme having a different substrate specificity.
However, the landscape analysis also reveals a multiplicity of case definitions, levels of clinician involvement, facility types, specimen collection, and laboratory techniques.
The very idea of multiplicity, he notes, only makes sense if one is talking about a collection of singularities.
The collection of cDNAs derived from the wp allele represents a multiplicity of processed RNAs varying in length and sequence that includes some identical to the correctly processed mature F3H transcript with three properly spliced exons.
This paradox, together with Burali-Forti's, led Cantor to formulate a concept called limitation of size, according to which the collection of all ordinals, or of all sets, was an "inconsistent multiplicity" that was "too large" to be a set.
Our survey concurs with the findings of others, that the difficulty of accurate data collection is compounded by duplication and unnecessary complexity caused by a multiplicity of registers [7].
