Alertness
Alertness is a state of active attention characterized by high sensory awareness. Someone who is alert is vigilant and promptly meets danger or emergency, or is quick to perceive and act. Alertness is a psychological and physiological state. Lack of alertness is a symptom of a number of conditions, including narcolepsy, attention deficit hyperactivity disorder, chronic fatigue syndrome, depression, Addison's disease, and sleep deprivation. Pronounced lack of alertness is an altered level of consciousness. States with low levels of alertness include drowsiness. The word is formed from "alert", which comes from the Italian (on the watch, literally: on the height; 1618). Wakefulness refers mainly to differences between the sleep and waking states; vigilance refers to sustained alertness and concentration. Both terms are sometimes used synonymously with alertness. Importance and difficulty People who have to be alert during their jobs, such as air traffic controllers or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vigilance (behavioural Ecology)
Vigilance, in the field of behavioral ecology, behavioural ecology, refers to an animal's monitoring of its surroundings in order to heighten awareness of predation, predator presence. Vigilance is an important behaviour during foraging as animals must often venture away from the safety of shelter to find food. However, being vigilant comes at the expense of time spent feeding, so there is a trade-off between the two. The length of time animals devote to vigilance is dependent on many factors including predation risk and hunger (motivational state), hunger. Vigilance is often observed in animals that forage in groups, such as yellow-eyed juncos (''Junco phaeonutus'') and meerkats (''Suricata suricatta''). Foraging in groups selfish herd theory, dilutes an individual's risk of predation, and allows them to reduce their own vigilance while the vigilance of the group is maintained.Davies, N.B., Krebs, J.R. & West, S.A.

Vigilance (psychology)
In modern psychology, vigilance, also termed sustained concentration, is defined as the ability to maintain concentrated attention over prolonged periods of time. During this time, the person attempts to detect the appearance of a particular target stimulus. The individual watches for a signal stimulus that may occur at an unknown time. The study of vigilance has expanded since the 1940s mainly due to the increased interaction of people with machines for applications involving monitoring and detection of rare events and weak signals. Such applications include air traffic control, inspection and quality control, automated navigation, military and border surveillance, and lifeguarding. Origins of research The systematic study of vigilance was initiated by Norman Mackworth during World War II. Mackworth authored "The breakdown of vigilance during prolonged visual search" in 1948 and this paper is the seminal publication on vigilance. Mackworth's 1948 study investigated the tendency ...

Vigilance Committee
A vigilance committee is a group of private citizens who take it upon themselves to administer law and order or exercise power in places where they consider the governmental structures or actions inadequate. Prominent historical examples of vigilance committees engaged in forms of vigilantism include abolitionist committees who, beginning in the 1830s, worked to free enslaved people and aid fugitive slaves, in violation of the laws at the time. However, many other vigilance committees were explicitly grounded in racial prejudice and xenophobia, administering extrajudicial punishment to abolitionists or members of minority groups. American vigilance committees Abolition and fugitive slaves Abolitionists met at Faneuil Hall in the 1830s and formed the Committee of Vigilance and Safety to "take all measures that they shall deem expedient to protect the colored people of this city in the enjoyment of their lives and liberties."

Vigilance Control
A dead man's switch is a switch that is designed to be activated or deactivated if the human operator becomes incapacitated, such as through death, loss of consciousness, or being bodily removed from control. Originally applied to switches on a vehicle or machine, it has since come to be used to describe other intangible uses, as in computer software. These switches are usually used as a form of fail-safe where they stop a machine with no operator from a potentially dangerous action or incapacitate a device as a result of accident, malfunction, or misuse. They are common in such applications as locomotives, Aviation fuel, aircraft refuelling, Elevator, freight elevators, lawn mowers, tractors, personal watercraft, outboard motors, chainsaws, snowblowers, treadmills, snowmobiles, amusement rides, and many medical imaging devices. On some machines, these switches merely bring the machines back to a safe state, such as reducing the throttle to idle or applying brakes while leaving t ...

ZPG-3W
The N-Class, or as popularly known, the "Nan ship", was a line of non-rigid airships built by the Goodyear Aircraft Company of Akron, Ohio for the US Navy. This line of airships was developed through many versions and assigned various designators as the airship designation system changed in the post World War II era. These versions included airships configured for both anti-submarine warfare and airborne early warning (AEW) missions. Design and development The initial version, designated ZPN-1, was a follow-on to the M-class blimp for patrol missions. The Nan ship used a significantly larger envelope than the M-ship although their overall lengths were similar. Two Wright R-1300 Cyclone 7 single-row, air-cooled radial engines powered the N-Class blimps.''Sky Ships: A History of the Airship in the United States Navy'', Althoff, W.F., Pacifica Press, c1991, An initial contract was awarded to the Goodyear Aircraft Company for the prototype N-class blimp in the late 1940s, with ...

USS Vigilance (AM-324)
USS ''Vigilance'' (AM-324) was an acquired by the United States Navy for the dangerous task of removing mines from minefields laid in the water to prevent ships from passing. ''Vigilance'' was originally laid down for the ''Royal Navy'' under the lend-lease program as HMS ''Exploit'' (BAM-24) on 28 November 1942 at Seattle, Washington, by Associated Shipbuilders. However, the United States Navy decided to keep the ship and renamed her USS ''Vigilance (AM-324)'' on 23 January 1943. Launched on 5 April 1943, the minesweeper was commissioned at her builder's yard on 28 February 1944.
