These differences in the operational definition of CSA may have contributed to variations in CSA prevalence and observed associations of CSA with PTB and gestational age at birth.
It is also possible that the discordance seen between our findings and others [ 7, 13, 15, 22, 23] stems, in whole or in part, from differences in the operational definition of "industry-sponsored research".
Differences in the operational definitions, the targeted disability domains, the population's profile, the data collection tools, the context and even the threshold or degree of disability measured, make difficult to compare or project estimates of older peoples' needs for help across different settings [ 11- 14].
Discrepancies in abuse rates could reflect differences in the operational definition of physical assault, types of participants and how the data are collected, although the figures from Canada suggest that factors other than sample characteristics and culture may be more important, requiring further investigation.
This could be due to difference in operational definition for the operators in different countries.
The difference in operational costs between the communities is due to the additional maintenance work carried out on the plant in Community X and the labour charged by the ESO.
For example, we observe only a slight difference in the transition point between operational modes determined by numerical simulations and the stability test (∼25 m2) and by the reduced state variables ((w^{0}-qapprox1.05) at 25 m2, as seen in Fig. 2 e)).
General McCarthy, now a professor of national security at the Air Force Academy, had a tepid review for the Navy's $30 billion DD-21 destroyer program, saying, "We didn't see a substantial difference in operational capabilities in the DD-21" compared with other Navy systems.
