The concept of mismatch , in its broadest sense, refers to a mismatch , a disconnection or a disarticulation . A mismatch is a difference between two elements that are generally concordant or should be concordant.
For example: "Currently there is a notable gap between the population's income level and prices" , "Justice is investigating a million-dollar gap in provincial accounts" , "The works could not be completed within the announced deadline because there was a gap in the delivery of materials .
In the field of physics , the idea of phase shift refers to a phase difference . This situation refers to the state presented by two magnitudes that are not simultaneous but have equal periods. The phase difference is the difference that is registered in the phases of the magnitudes considered.
On the other hand, the difference in the time of two places is called time lag . Suppose that, when the clock in one city reads 10 a.m., in another town it is 3 p.m. There is, therefore, a five-hour time lag between both sites.
In relation to this meaning of lag, we have to establish that there is a health problem that responds to the name of jet lag. Specifically, it is a sleep disorder that can be suffered by people who travel to different places in the world that are in different time zones. And this occurs because the body of the aforementioned citizens has a circadian rhythm that marks when to sleep and even when to get out of bed.
This "confrontation" between what the body establishes and the different schedules it faces means that the individual in question not only has problems falling asleep but also feels tired throughout the day, may suffer headaches, appear very irritable, suffer stomach pains and even have a general feeling of not feeling well.
To be able to cope with this jet lag you have to eat healthy, exercise, rest a lot, drink plenty of water and avoid exciting things.
It should be noted that the term lag can also be mentioned as phase lag . Although desfasaje is not part of the dictionary of the Royal Spanish Academy ( RAE ), it is included in the Pan-Hispanic Dictionary of Doubts of said institution. Defasaje is a word derived from desfasar that was created by analogy to the French déphasage . In some South American countries, desfasaje is used more frequently than desfasaje, unlike what happens in Spain and other nations.
The term in question is also used within the field of education. Specifically, we speak of curricular gap, which is used to refer to students who are attending classes in a subject in which they have a level of knowledge and skills that is lower than what they should already have. Hence they need curricular adaptations.
Thus, it can be said that students may have a curricular gap, for example, with specific needs such as severe behavioral disorders, severe learning difficulties, with disabilities, with attention deficit disorders...
