What is Expulsion:
Expulsion is understood as the action of expelling, that is, of taking someone or something out.
It comes from the Latin term I will expel, composed of the prefix former, which means "outward", and the conjugation of the verb pellere, which means "to throw, to push or to propel".
Socially, expulsion is a sanction that is applied to a subject who has broken the contract or social pact and that consists of removing him or her from the group of belonging definitively, whatever the nature.
The term is generally used in various contexts and implies different degrees of severity depending on them. Thus, an expulsion can be carried out in the political, legal, scientific, sports, school and institutional spheres, among others.
Thus, the word expulsion is usually related to terms such as extraction, elimination, extradition, exile, exile, deportation, dismissal, dismissal or overthrow.
Expulsion in the legal-political sphere
In the legal-political sphere, expulsion is applied against foreigners for various factors. From the legal point of view, the justifications for the expulsion of a foreigner are usually three: 1) not possessing residence documents; 2) having committed a crime that carries the penalty of expulsion and, 3) conspiring against the government of the host country.
However, there have been many occasions in history when the expulsion of foreigners has been related to intolerance, racism and xenophobia, sometimes masked by legal, social, religious or economic justifications. An example is the case of the expulsion of Jews and Moors from the Iberian Peninsula in the 15th century.
Expulsion in sport
As far as sport is concerned, unsportsmanlike conduct, disregard of the rules of the game and disregard of the team's disciplinary rules can lead to the expulsion of the player. Example: "Due to his unsportsmanlike behavior, he had to be expelled from the team."
Expulsion in education
The same occurs also in the educational environment, from basic education to university education.
Indiscipline, constant contempt for authority, hate crimes on campus, abusive behavior, frequent insistence and, to a lesser degree, poor academic performance, are causes of expulsion from the educational community, which may be partial or total depending on the seriousness of the matter.
Example: "To discipline the student, the school principal decided to expel him from school for three days."
Expulsion in science
One can also speak of expulsion in relation to objects or bodies in the scientific field. Examples of the use of the term expulsion in science:
- "The rapid expulsion of gases is what mobilizes the rocket" (Physics).
- "The second period of labor culminates with the total expulsion of the fetus" (Medicine).
- "An expulsion is a small, generally conical cavity in a horizontal concrete surface that occurs after a particle of aggregate (or aggregate) near the surface has expanded or fractured." NMRCA: Concrete in practice.
