Such an approach fits well with a case study method [ 31] that allows the exploration of a particular phenomenon within dynamic contexts where multiple influencing variables are difficult to isolate [ 32].
Even if analyses are corrected for multiple influences, there might be unknown confounders changing the results.
The multiple layers of influence are summed up in his description of the transformation of Miami by Cubans fleeing Castro's revolution after 1959: "Miami began as an imitation of Havana in the 1920's and 1930's, then was imitated by Havana during the 1940's and 1950's; in the 1960's it was a copy of a copy that was copied".
Key questions about how lifestyle behaviours should be modified to address the problem of childhood obesity on a global stage can be best answered by a multi-national study in which both physical activity and dietary intake are measured in a standardized manner, and key measures of the multiple levels of influence are obtained in several countries.
We fully acknowledge that for this intervention to be successful, appreciation of the multiple influences upon behaviour is required.
With respect to the etiology of functional neurological symptom disorder, multiple influences of different weight are to be considered, including conditioning processes, object relations and identification processes, narcissistic regulation, unconscious (libidinous) strives and conflicts, trauma and personality traits, as well as the social context [ 12, 13, 23].
Multiple influences can also be detected in the work of Gustavo Casenave, a Uruguayan pianist and composer active in classical, jazz and tango scenes.
Highlighting the importance of a multidimensional approach, physicians negotiated multiple influences when death was regarded as hastened.
The social ecological model posits that physical activity is subjected to multiple influences [ 24], which is reflected in the multi-dimensional factorial structure identified in this study.
As discussed above, there are multiple influences on the value of an option, any of which might be influenced by external factors such as rules or attention.
