Open data sources Practice is based on an extensive variety of data, information including intelligence and knowledge drawn from a wide range of sources. Collection, collation and evaluation are three inter-linking steps of the intelligence cycle, however, evaluation can occur at every stage. Practitioners should maintain their knowledge of potential sources of information as well as a description of the information available, its reliability, validity and accuracy.
Pros and Cons Conceptually simple, easy to grasp. Works well in combination with other methods. Results translate naturally into corrective action recommendations. Can be used to find causes that are obscure, or that defy discovery using other methods.
Cons Requires some basis for comparison. Resource intensive, requires exhaustive characterization of deviation. Applicable only to a single, specific deviation. Provides only direct causes for a deviation. Results may not be conclusive; testing usually required. A discrete difference between an occurrence exhibiting the deviation, and a similar occurrence that did not exhibit the deviation.
A situation in which actual results or actual performance differed from what was expected. Discussion As suggested by the name of the technique, change analysis is based on the concept that change or difference can lead to deviations in performance.
This presupposes that a suitable basis for comparison exists. What is then required is to fully specify both the deviated and undeviated conditions, and then compare the two so that changes or differences can be identified. Any change identified in this process thus becomes a candidate cause of the overall deviation.
What is a suitable basis for comparison? There are basically three types of situations that can be used. First, if the deviation occurred during performance of some task or operation that has been performed before, then this past experience can be the basis.
Second, if there is some other task or operation that is similar to the deviated situation, then that can be used. Finally, a detailed model or simulation of the task including controlled event reconstruction can be used, if feasible.
Once a suitable basis for comparison is identified, then the deviation can be specified. Various schemes exist for performing this specification.
Regardless of the scheme used, the end result should be a list of characteristics that fully describe the deviated condition. Given the full specification of the deviated condition, it becomes possible to perform a detailed comparison with the selected undeviated condition. Each difference between the deviated and undeviated situations is marked for further investigation.
In essence, each individual difference or some combination of differences is a potential cause of the overall deviation.Problem Trees A ‘Problem Tree’ or ‘issue tree’ is a type of diagram which enables community members to analyse the causes and effects of a particular problem, and how they relate to one another.
Geophysical survey is the systematic collection of geophysical data for spatial studies.
Detection and analysis of the geophysical signals forms the core of Geophysical signal processing. The magnetic and gravitational fields emanating from the Earth's interior hold essential information concerning seismic activities and the internal structure.

Many studies have examined ‘morphometric’ neuroimaging of meditation practitioners. • We conduct a meta-analysis of these gray and white matter differences in meditators.
Change management is when companies undergo significant shifts in operations as a result of internal or external forces. Management often spends time reviewing and evaluating changes prior to starting the process, in hopes of saving capital and preventing significant disruptions to the company’s operations.
