Gatekeeper

A gatekeeper is a person who controls access to something, for example via a city gate. In the late 20th century the term came into metaphorical use, referring to individuals who decide whether a given message will be distributed by a mass medium.

Gatekeeping roles

Gatekeepers serve in various roles including academic admissions, financial advising, and news editing. An academic admissions officer might review students' qualifications based on criteria like test scores, race, social class, grades, family connections, and even athletic ability. Where this internal gatekeeping role is unwanted, open admissions can externalize it.

Various gatekeeping organizations administer professional certifications to protect clients from fraud and unqualified advice, for example for financial advisers.

A news editor selects stories for publication based on his or her organization's specific criteria, e.g., importance and relevance to their readership. For example, a presidential resignation would be on the front page of a newspaper but likely not a celebrity break-up (unless the paper was of the gossip variety).

Gatekeeper (butterfly)

The gatekeeper (Pyronia tithonus), sometimes called the hedge brown, is most commonly found in South and East Britain, and confined to coastal areas of south and southeast Ireland. It is also found in the Channel Islands, but not in Scotland nor the Isle of Man. Given its preference for warmer weather, it can be assumed that the restriction of range expansion is due to climate. Colonies will vary in size depending on the available habitat, and can range from a few dozen to several thousand butterflies.

Similar species and subspecies

It is a member of the subfamily Satyrinae in the family Nymphalidae. A similar species is the meadow brown; the two species can be difficult to distinguish with closed wings since the underwing markings are very similar. However, the gatekeeper tends to rest with its wings open, whereas the meadow brown usually rests with its wings closed. The gatekeeper is also smaller and more orange than the meadow brown and has double pupils on its eyespots.

Exo (novel)

Exo is the fourth novel in the Jumper series by Steven Gould and the fifth in the Jumper universe. The first two novels—Jumper and Reflex—tell a connecting story of David and Millie, which is continued with their daughter, Cent, in Impulse and now Exo. The fifth novel in the Jumper universe, Jumper: Griffin's Story, is the back-story for a character from the 2008 movie Jumper and is not associated with the story or characters in the novels.

Jumping

It seems that the ability to teleport or jump can be learned. David was the first one and just did it, but Millie and Cent did it under stress after being jumped lots of times. In the different sequels of the series the main characters discover different principles to their capabilities of jumping.
