In other words, the traditional evaluation of performance in terms of productivity, using ton-km as an indicator of output, can only be applied to one of the four service trajectories that we have identified (Table 5).
As a matter of fact, the ton-km remains, at the same time, the most widely criticized and most wide-spread indicator of output of the freight transport sector, which leads to an erroneous representation of freight transport performance.
Decker (1980) examines police productivity using indicators of output, while Stevens, Webster and Stipak (1980) focus on response times.
These limitations were powerfully stated in the report of a recent study of 15 European countries, which showed that "analysis and evaluation of PE [public engagement] activities is still underdeveloped, lacking robust and shared indicators of output and performance" [ 141].
The RSI has a weak negative correlation with the indicators of output and citation, meaning that no association can be established between volume and specialization, or between specialization and visibility.
The most commonly used indicator of national output is the gross national product (GNP), which is a measure of the total market value of currently produced finished goods and the value of services rendered.
A system was developed for the simultaneous measurement in urine of free catecholamines (i.e., dopamine, norepinephrine, epinephrine) and creatinine (i.e., an indicator of urine output and volume).
A simple and generalizable indicator of research output is defined.
My hypothesis is that a useful indicator of research output can be constructed, based on three variables.
We believe the most reliable indicator of cardiac output is the Fick and dye-dilution, however, this is impractical to perform in the acute setting.
Pump flow (an indicator of cardiac output) is displayed on the LVAD screen; therefore, pulmonary artery (PA) catheters provide little additional information.
