In operational definition A, highway safety is defined as the total number of crashes in a calendar year as reported in the Utah Crash Summary (1995) as prepared by Utah Department of Public Safety.
In the second operational definition we have defined highway safety as "the percent of alcohol-related deaths as recorded in the Utah Crash Summary." Notice that this is a very different operational definition of highway safety, one that focuses on the issue of driving under the influence of alcohol.
Let's say our operational definition, which is fairly similar to the one we used previously, is the total number of fatalities in one year on Utah roads, as measured and reported by the Utah Department of Public Safety in their annual Utah Crash Summary.

 Operational Risk
Operational risk has also turned out to be more costly in terms of capital than most institutions realised - recent estimates put it at 25% or more of risk capital.
But operational risk is a more difficult nut to crack because of the paucity of data, the many different frequencies and severities of loss, the multiple categories of risk that have to be considered, and the difficulty of linking a loss event to a single cause.
One of the cutting-edges of operational risk research is therefore the application of a body of theory known as Extreme Value Theory to the scarce data that is available on catastrophic risks.

Definitions for four sets of subsidies are needed in order to advance the measurement, analysis and discussion of subsidies in fisheries and aquaculture.

Unfortunately, this story has fairly little to do with operational definitions as they were proposed in the 1920s, and, further, there is fairly little in the way of rigorous argument to recommend it.

Each operational definition is likely to be incomplete, capturing only one small part of the meaning of your construct.

This definition serves our needs in several regards: it identifies speech varieties that are of broad interest in linguistic research, and it identifies speech varieties that are of greatest interest for purposes of language-related development, such as literacy.
Regardless of the exact operational definition used to categorize languages, there is no debate that the number of languages spoken in the world today is very large, on the order of several thousand.
We have argued that the operational definition on which a categorization of languages is based must be stated clearly, and have shown that existing systems of identifiers have significant problems in this regard.

Operational definitions, on the other hand, describe a concept in terms of observable or measurable characteristics or behaviors, by specifying how the concept can be observed in actual practice in the real world.¡ll€óŸ¨Operational Definitions¡Ÿ¨ Identifying and determining how to measure the observable, or empirical characteristics of the concepts you wish to study.
An operational definition identifies one or more specific observable conditions or events and then tells the researcher how to measure that event¡  €ó Ÿ¡€ª Ÿ¨»When you operationalize an abstract term, you take word definition a step beyond the commonsense view of it.
However, operational definitions rarely capture completely all the dimensions of sophisticated concepts When many observable characteristics are included in an operational definition, you, as a researcher, must decide which ones are more essential than others for defining the abstract concept.¡ll€ª=ó#Ÿ¨"Evaluating operational definitions¡*#"€„Ÿ¨uAdequacy: Is the definition or operationalization adequate?
