In order to ensure that the measured content represents the construct that is being measured, four aspects are considered: conceptuality, representativeness, relevance and appropriateness of the development process.
We have measured three aspects of FtsZ filament dynamics at steady state: rates of GTP hydrolysis, subunit exchange between protofilaments, and disassembly induced by dilution or excess GDP.
In addition to nest mass, we measured five aspects of nest morphology: 1) external nest diameter, 2) internal nest-cup diameter, 3) external nest depth, 4) internal nest-cup depth, and 5) nest-wall thickness.
The SDS scale measured three aspects of four principal symptoms of FD.
Known as Gravity Probe B, the experiment used four ultra-precise gyroscopes housed in a satellite to measure two aspects of Einstein's theory about gravity.
The report measures two aspects of a city's brand: its "assets" – attractions, climate, infrastructure (particularly transport), safety and economic prosperity – and its "buzz", a combination of social media (Facebook likes and Twitter sentiment analysis) and media mentions.
After decades of development, Gravity Probe B circled Earth from pole to pole for 17 months starting 20 April 2004 and used gyroscopes to measure two aspects of general relativity.
These two variables were, by definition, highly collinear (correlation coefficient of 0.74), measuring two aspects of bilateral CIs.
Following a review of the safety culture literature, a questionnaire was designed to measure five aspects of organisational safety indicative of five levels of cultural maturity.
