Our analysis demonstrates that it is imperative to clearly formulate the physical nature of the actual measurement afforded by a directional radiometer rather than presume desirable measurement capabilities.
Even though this would have been a desirable measurement to record and include as a co-variable, performing it would have introduced the confounding effects of additional stimuli to our experimental design, which would have changed the entire learning paradigm, and made the results difficult to interpret.
Where they occur, reactive effects on behavior are usually positive, i.e., where the behavior is desirable, measurement produces an increase.
Although desirable, measurement of absolute counts was not feasible due to the conditions of data collection and the need to transport samples to Prague.
The previous ADA and JNC-7 target BP defined the desirable BP measurements (8, 19).
Exact distances and distance distributions are desirable when solution measurements must be compared to crystal structures, generally to distinguish between models of how a particular protein or nucleic acid functions.
High contrast with background was particularly desirable for VIA measurements.
As it is desirable that growth measurements should be taken during the period when infant formula remains an exclusive source of nutrition for an infant, we focused on supplementation during early infancy.
It would also have been desirable to obtain measurements, at the same time points, on other factors that have been linked to pain responses such as anti-inflammatory cytokines [ 58], catecholamines [ 59], growth hormone [ 60], and blood pressure reactivity (a useful index of sympathetic nervous system activation in the context of pain responses [ 61, 62]).
It is also possible to measure breast density with other imaging modalities, such as ultrasound and MRI, which do not require the use of ionizing radiation and may, therefore, be more suitable for use in young women or where it is desirable to perform measurements more frequently.
