1. vi. [orig. from BASIC's CHAIN statement] To hand off execution to a child or successor without going through the OS command interpreter that invoked it. The state of the parent program is lost and there is no returning to it. Though this facility used to be common on memory-limited micros and is still widely supported for backward compatibility, the jargon usage is semi-obsolescent; in particular, most Unix programmers will think of this as an exec. Oppose the more modern subshell.

2. n. A series of linked data areas within an operating system or application. Chain rattling is the process of repeatedly running through the linked data areas searching for one which is of interest to the executing program. The implication is that there is a very large number of links on the chain.


 

A land surveyor’s standard distance-measuring device. Also see Gunter’s chain.


 

1. A concept that suggests that in a movement consisting of a number of components occurring in a sequence, termination of early components results in sensory feedback, which acts as a stimulus initiating the next component, and so on until the movement is completed.

2. A method of learning a skill consisting of several actions linked in a series in which the completion of each action initiates the next action (for example, a floor routine in gymnastics). The components are learnt in the same sequence as they are performed. Compare backward chaining method.

 
flexible series of connected links used in various ways, especially for the transmission of motive power, for hoisting (see pulley), and for securing or fastening. Commonly, mechanical energy from a motor or other source applied to a sprocket wheel is conveyed by means of an endless chain to another sprocket wheel for driving a mechanism. Examples of such an arrangement are found in bicycles, motorcycles, and conveyor belts. The chain in this application is so designed that each consecutive link fits over a sprocket, the distance between links being called the pitch. The relative speed of the wheels varies according to their relative circumferences and, thus, the number of sprockets on each. There are several types of chain for the transmission of power. A detachable-link chain has links that are simple rectangles, each with a connecting hook at one end by which it is attached to the next link. A pintle chain has links that are approximately U-shaped. The closed end of each link fits into the open end of the next one; a pin holds the two links together. A block chain consists of metal blocks that are joined together by side plates and pins to form links. A roller chain has links consisting of side plates with hollow cylindrical rollers between them. Pins pass through the rollers and side plates to hold the links together. A silent, or inverted-tooth, chain has links made of toothed metal plates. A number of these links are placed side by side to form a group. Each group is joined to another one by meshing the ends of the links of both groups and inserting a pin there. By repeating the process a chain can be formed. Its width can be varied by varying the number of links in a group. Although not completely silent, this type of chain is quieter than other power transmission chains. The coil chains used in hoists and for locking or fastening purposes are of the open-link type, comprising solid interlocked rings, or of the stud-link type, in which a stud, or bar, across the link keeps the chain from kinking.


 

A collection of objects linked together in linear fashion, or end to end, as the assemblage of atoms or radicals in a chemical compound, or an assemblage of individual bacterial cells.

  • c. binomial model — model of an outbreak of an infectious disease in which the outbreak is depicted as a series of steps with a binomial statement of the probability of an outcome at each step.
  • branched c. — an open chain of atoms, usually carbon, with one or more side chains attached to it.
  • heavy c. — any of the large polypeptide chains of five classes that, paired with the light chains, make up the antibody molecule. Heavy chains bear the antigenic determinants that differentiate the immunoglobulin classes. See also heavy-chain disease.
  • J c. — a polypeptide occurring in polymeric IgM and IgA molecules.
  • light c. — either of the two small polypeptide chains (molecular weight 22,000) that, when linked to heavy chains by disulfide bonds, make up the antibody molecule; they are of two types, kappa and lambda, which are unrelated to immunoglobulin class differences.
  • light c. disease — the overproduction of immunoglobulin light chain molecules by certain B cell tumors (plasmacytomas). See monoclonal gammopathy.
  • obstetric c. — used in obstetrics in cattle and horses to snare extremities and for traction. Made of rustproof metal with links designed not to kink or to jam. They have a loop link at each end to facilitate single-handed formation of a loop. The links are shaped so that the ring-grip handles used for traction will grip at any point and stay put with the strongest pull.
  • c. shank — a leather lead with a short section of chain at the proximal end. It can be placed over the horse's nose, through the mouth or across the upper gum for greater control.
  • side c. — a chain of atoms attached to a larger chain or to a ring.
  • stallion c. — strong chain, 1–2 ft (0.5 m) long, at the end of a solid lead. For leading a stallion with little chance of his biting through the lead.
  • c. termination method — See sanger–coulson method.

An all-chain anchor rode is comforting when it’s down and doing its work. But raising it, even with mechanical help, can be very hard work. Nevertheless, it has so many advantages over a rope rode that most long-distance cruisers use nothing but chain with their working anchors.

Three kinds of anchor chain.
Proof-coil chain is made of low-carbon steel and has relatively long links. Its breaking strength is three and a half to four times its working load limit. But the chain most commonly used in cruising yachts is BBB chain. It’s made from the same material as proof-coil chain, but it has shorter links that fit better in windlasses. It has the same breaking strength as proof-coil.High-test chain is stronger than the other two types, for the same weight, because it has a higher carbon content. But it is more prone to rust and its breaking strength is about three times the working load limit. It may part without warning when its limits are reached, whereas the softer proof-coil and BBB chains will first elongate to warn you. High-test chain is often used aboard performance cruisers where weight is considered detrimental. All three types are supplied with a galvanized-zinc coating.Whatever kind of chain you use, make sure the bitter end is firmly secured to the inside of the chain locker. Use strong nylon line for this, so that it will absorb some of the shock if the chain ever runs away from you and fetches up sharply at the bitter end. And make the nylon line long enough to reach the deck, so you can cut the cable quickly and dump the anchor and chain in an emergency (mariners call it “slipping the cable”).See also Chain Stoppers; Rodes.

Wikipedia: Chaining

Chaining is an instructional procedure used in Behavioral psychology, experimental analysis of behavior and applied behavior analysis. It involves reinforcing individual responses occurring in a sequence to form a complex behavior. It is frequently used for training behavioral sequences (or "chains") that are beyond the current repertoire of the learner.

Procedure

The chain is broken down into steps using task analysis. The learner is then taught each step individually. The chain is set in motion through the use of a stimulus, or prompt. Eventually, each step, or link, in the chain becomes the discriminative stimulus for the following link. The final step is usually associated with some sort of natural reinforcer, a stimulus that increases the probability of behavior and is a natural consequence of performing the behavior.

As the earlier steps become associated with the latter steps through classical conditioning, the steps begin to take on reinforcement value. Thus, the occurrence of a later link after an earlier link increases the probability that the organism will perform the earlier link again (which will serve as a prompt for the later link). As small chains become mastered, i.e. are performed consistently following a single discriminative stimulus, they may be used as links in larger chains. Each chain then becomes a discriminative stimulus for the following chain and a reinforcer for the previous chain. The most common forms of chaining are backward chaining, forward chaining, and total task presentation.
