Voluntary (music)
In music a voluntary is a piece of music, usually for an organ, that is played as part of a church service. In English-speaking countries, the music played before and after the service is often called a 'voluntary', whether or not it is so titled. The title 'voluntary' was often used by English composers during the late Renaissance, Baroque, and Classical periods. Originally, the term was used for a piece of organ music that was free in style, and was intended to sound improvised (the word voluntary in general means "proceeding from the will or from one's own choice or consent"). This probably grew out of the practice of church organists improvising after a service. The style is in almost complete contrast to the liturgical chorale preludes of J S Bach and others, where the composition is almost invariably based round the theme of a seasonal chorale (Lutheran hymn). Later, the English voluntary began to develop into a more definite form, though it has never been strictly defined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volunteering
Volunteering is a voluntary act of an individual or group freely giving time and labor for community service. Many volunteers are specifically trained in the areas they work, such as medicine, education, or emergency rescue. Others serve on an as-needed basis, such as in response to a natural disaster. Etymology and history The verb was first recorded in 1755. It was derived from the noun ''volunteer'', in 1600, "one who offers himself for military service," from the Middle French ''voluntaire''. In the non-military sense, the word was first recorded during the 1630s. The word ''volunteering'' has more recent usage—still predominantly military—coinciding with the phrase ''community service''. In a military context, a volunteer army is a military body whose soldiers chose to enter service, as opposed to having been conscripted. Such volunteers do not work "for free" and are given regular pay. 19th century During this time, America experienced the Great Awakening ...

Muscle Contraction
Muscle contraction is the activation of tension-generating sites within muscle cells. In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as when holding something heavy in the same position. The termination of muscle contraction is followed by muscle relaxation, which is a return of the muscle fibers to their low tension-generating state. For the contractions to happen, the muscle cells must rely on the interaction of two types of filaments which are the thin and thick filaments. Thin filaments are two strands of actin coiled around each, and thick filaments consist of mostly elongated proteins called myosin. Together, these two filaments form myofibrils which are important organelles in the skeletal muscle system. Muscle contraction can also be described based on two variables: length and tension. A muscle contraction is described as isometric if the muscle tension changes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voluntary Action
Voluntary action is an anticipated goal-oriented movement. The concept of voluntary action arises in many areas of study, including cognitive psychology, operant conditioning, philosophy, neurology, criminology, and others. Additionally, voluntary action has various meanings depending on the context in which it is used. For example, operant psychology uses the term to refer to the actions that are modifiable by their consequences. A more cognitive account may refer to voluntary action as involving the identification of a desired outcome together with the action necessary to achieve that outcome. Voluntary action is often associated with consciousness and will. For example, Psychologist Charles Nuckolls holds that we control our voluntary behavior, and that it is not known how we come to plan what actions will be executed. Many psychologists, notably Tolman, apply the concept of voluntary action to both animal and human behavior, raising the issue of animal consciousness and its rol ...

Voluntariness
In law and philosophy, voluntariness is a choice being made of a person's free will, as opposed to being made as the result of coercion or duress. Philosophies such as libertarianism and voluntaryism, as well as many legal systems, hold that a contract must be voluntarily agreed to by a party in order to be binding on that party. The social contract rests on the concept of the voluntary consent of the governed. The Federal Rules of Criminal Procedure provide that "Before accepting a plea of guilty or nolo contendere, the court must address the defendant personally in open court and determine that the plea is voluntary and did not result from force, threats, or promises (other than promises in a plea agreement)." The actual voluntariness is suspect, in that it is common for prosecutors to threaten to seek more prison time unless the defendant agrees to plead guilty. For this reason, common law In law, common law (also known as judicial precedent, judge-made law, or case law) is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
