Harbor

A harbor or harbour (see spelling differences), or haven, is a body of water where ships, boats and barges seek shelter from stormy weather, or are stored for future use. Harbors and ports are often confused with each other. A port is a facility for loading and unloading vessels; ports are often located in harbors.

Harbors can be natural or artificial. An artificial harbor can have deliberately constructed breakwaters, sea walls, or jettys, or they can be constructed by dredging, which requires maintenance by further periodic dredging. An example of an artificial harbor is Long Beach Harbor, California, which was an array of salt marshes and tidal flats too shallow for modern merchant ships before it was first dredged in the early 20th century.

In contrast, a natural harbor is surrounded on several sides by prominences of land. Examples of natural harbors include Sydney Harbour, Australia and San Francisco Bay, California.

Artificial harbors

Artificial harbors are frequently built for use as ports. The oldest artificial harbor known is the Ancient Egyptian site at Wadi al-Jarf, on the Red Sea coast, which is at least 4500 years old (ca. 2600-2550 BC, reign of King Khufu). The largest artificially created harbor is Jebel Ali in Dubai. Other large and busy artificial harbors include:

Harbor (MBTA station)

Harbor was a passenger rail station on the Rockport Branch of the MBTA Commuter Rail Newburyport/Rockport Line. A short-lived stop, it was open from 1977 to 1985.

History

Harbor station opened in December 1977 to serve a new apartment complex (now The Heights at Cape Ann) located on a bluff above the tracks. Several short turn trains (which had formerly terminated at Manchester but ran to an interlocking just west of Gloucester to switch tracks for the inbound journey) were extended to Harbor at that time. Several trips, including the short turns, were cut in September 1979. On January 30, 1981, service to nearby West Gloucester was discontinued during a round of budget cuts, leaving Harbor as the only station serving the area.

The station was never heavily used - an April 1983 count showed just 35 daily boardings. On November 16, 1984, a fire destroyed Beverly Draw, which connects Salem and Beverly Depot on the line. A shuttle train continued to operate from Rockport to Beverly until January 7, 1985, when it was replaced by bus service. The locomotives used were then trucked to Danvers so they could be repaired at the MBTA's main maintenance facility. When service was restored on December 1, 1985, Harbor station remained closed. West Gloucester, which had more room for parking, reopened instead.

Harbor (album)

Harbor is the seventh original studio album by American folk rock trio America, released by Warner Bros. Records in February 1977. It was the last to feature Dan Peek, who embarked on a solo Christian career shortly after the album's release. The album was produced by George Martin.

Though a major commercial disappointment compared to America's six previous albums, the album did reach number 21 on the Billboard album chart. Three singles ("God of the Sun", "Don't Cry Baby" and the disco song "Slow Down") were released from the album but all failed to chart, although "God of the Sun" and "Now She's Gone" did get some airplay.

Despite the serene tone of the title and artwork, Harbor is more brooding and pessimistic than most of America's previous albums.

Learning

Learning is the act of acquiring new, or modifying and reinforcing, existing knowledge, behaviors, skills, values, or preferences and may involve synthesizing different types of information. The ability to learn is possessed by humans, animals, plants and some machines. Progress over time tends to follow a learning curve. It does not happen all at once, but builds upon and is shaped by previous knowledge. To that end, learning may be viewed as a process, rather than a collection of factual and procedural knowledge. Learning produces changes in the organism and the changes produced are relatively permanent.

Human learning may occur as part of education, personal development, schooling, or training. It may be goal-oriented and may be aided by motivation. The study of how learning occurs is part of educational psychology, neuropsychology, learning theory, and pedagogy. Learning may occur as a result of habituation or classical conditioning, seen in many animal species, or as a result of more complex activities such as play, seen only in relatively intelligent animals. Learning may occur consciously or without conscious awareness. Learning that an aversive event can't be avoided nor escaped is called learned helplessness. There is evidence for human behavioral learning prenatally, in which habituation has been observed as early as 32 weeks into gestation, indicating that the central nervous system is sufficiently developed and primed for learning and memory to occur very early on in development.
