Overlap is the act and the result of superimposing . East verb , which comes from the Latin word I will superimpose, refers to locate something about something else or to make two elements light up . For example: “Overlapping papers on the desk will not help you find the document you are looking for”, “There is an overlap of schedules: if I go to Dr. Laurroetz's conference, I cannot attend the bioethics colloquium”, “This overlapping of functions is not compatible with the position it holds”.
Suppose a person Start displaying pictures on a table. Once it covers the entire surface, start placing more photos on the previous ones. In this way, perform a photo overlay : There are images that are located over others, and this prevents the correct display of all.
Another case of overlap can be found when someone performs two activities that involve a conflict of interests . If a man He is an official of the Ministry of Energy of a country and, in addition, works as an advisor to an oil company, there is a function overlay : the subject cannot work for the State if you also defend the interests of a private company .
It should be noted that this particular case is not so common, since companies, and much more the State, have resources to prevent their employees from putting in risk your interests; For example, there are clauses in employment contracts that limit the activities of the person outside the workplace, as well as agreements outside the contract that deal with these issues in a specific and very detailed way.

In the same way, when any of the activities performed by an employee outside their work can generate an overlap of interests , the entities with which you have signed a contract must take action on the matter and resolve the conflict. This is very common in cases in which a post of those mentioned in the previous paragraph is combined with the writing of news blogs in the same field, for example, since there is a risk of confidential information being leaked.
The idea of overlap also appears on land such as math (he overlapping principle applies to the decomposition of a trouble in two or more problems of less complexity) and the geology (when successive layers of sediment accumulate, leaving the oldest in the lower sector).
In the video edition , the image overlay It is done many times with the intention of changing the background of one of them, to give the feeling that an object or subject is in a different place than it was when they filmed it.
