Defender (association football)

In the sport of association football, a defender is an outfield player whose primary role is to prevent the opposing team from scoring goals.

There are four types of defenders: centre-back, sweeper, full-back, and wing-back. The centre-back and full-back positions are essential in most modern formations. The sweeper and wing-back roles are more specialised for certain formations.

Centre-back

A centre-back (also known as a central defender or centre-half) defends in the area directly in front of the goal, and tries to prevent opposing players, particularly centre-forwards, from scoring. Centre-backs accomplish this by blocking shots, tackling, intercepting passes, contesting headers and marking forwards to discourage the opposing team from passing to them.

With the ball, centre-backs are generally expected to make short and simple passes to their teammates, or to kick unaimed long balls down the field. For example, a clearance is a long unaimed kick intended to move the ball as far as possible from the defender's goal.

Back (song)

"Back" is a song co-written and recorded by American country rap artist Colt Ford. It is a duet with Jake Owen, and the second single from Ford's fourth studio album, Declaration of Independence.

Critical reception

Ashley Cooke of Roughstock gave it a full 5 stars, saying that the song "genuinely tugs at your heart -strings. If you were lucky enough to grow up with memories similar to the lyrics in this song, you will find yourself in love with it just as I did." Billy Dukes of Taste of Country gave it 2.5 stars out of 5, saying that it was "about a verse too long" and that it "isn't a step backward, but it's no step forward."

Field extension

In abstract algebra, field extensions are the main object of study in field theory. The general idea is to start with a base field and construct in some manner a larger field that contains the base field and satisfies additional properties. For instance, the set Q(√2) = {a + b√2 | a, b ∈ Q} is the smallest extension of Q that includes every real solution to the equation x² = 2.

Definitions

Let L be a field. A subfield of L is a subset K of L that is closed under the field operations of L and under taking inverses in L. In other words, K is a field with respect to the field operations inherited from L. The larger field L is then said to be an extension field of K. To simplify notation and terminology, one says that L / K (read as "L over K") is a field extension to signify that L is an extension field of K.

If L is an extension of F which is in turn an extension of K, then F is said to be an intermediate field (or intermediate extension or subextension) of the field extension L / K.

Academic degree

An academic degree is the state of recognized completion of studies at a school or university. A diploma is generally issued in recognition of having satisfactorily completed the prescribed course of study. The two most common degrees awarded today are associate and bachelor's.

Higher education institutions commonly offer master’s, doctoral, academic certificates, and professional degrees.

Overview

The modern academic system of academic degrees evolved and expanded in the medieval university, spreading everywhere across the globe as the institution did:

Emergence of the doctor’s and master’s degrees and the licentiate

The doctorate (Latin: doceo “I teach”) appeared in medieval Europe as a license to teach (Latin: licentia docendi) at a medieval university. Its roots can be traced to the early church when the term "doctor" referred to the Apostles, church fathers and other Christian authorities who taught and interpreted the Bible. The right to grant a licentia docendi was originally reserved to the church which required the applicant to pass a test, to take oath of allegiance and pay a fee. The Third Council of the Lateran of 1179 guaranteed the access – now largely free of charge – of all able applicants, who were, however, still tested for aptitude by the ecclesiastic scholastic. This right remained a bone of contention between the church authorities and the slowly emancipating universities, but was granted by the Pope to the University of Paris in 1231 where it became a universal license to teach (licentia ubique docendi). However, while the licentia continued to hold a higher prestige than the bachelor's degree (Baccalaureus), it was ultimately reduced to an intermediate step to the Magister and doctorate, both of which now became the exclusive qualification for teaching.
