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.

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.

"The chains that bind" may portend a happy union or marriage or be the missing link to the solution of a problem or situation. A succession of events can be linked together in a chain reaction. Ideas and opinions can be bound up in old ways of doing things. The dreamer may be needing to break free of the chains that bind or to link up with new ideas, people, or situations. (See also Rope).

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.

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. The term is often credited to the work of B.F. Skinner, an American psychologist working at Harvard University in the 1930s. Skinner based most of his work on the research done by Edward Lee Thorndike at Harvard University in the 1890s.

Procedure

The chain of responses is broken down into small steps using task analysis. Parts of a chain are referred to as links. The learner's skill level is assessed by an appropriate professional and is then either taught one step at a time while being assisted through the other steps forward or backwards or if the learner already can complete a certain percentage of the steps independently, the remaining steps are all worked on during each trial total task. A verbal stimulus or prompt is used at the beginning of the teaching trial. The stimulus change that occurs between each response becomes the reinforcer for that response as well as the prompt/stimulus for the next response without requiring assistance from the teacher. For example, in purchasing a soda you pull the money out of your pocket and see the money in your hand and then put the money in the machine. Seeing the money in your hand both was the reinforcer for the first response (getting money out of pocket) and was what prompted you to do the next response (putting money in machine).

As small chains become mastered, i.e. are performed consistently following the initial discriminative stimulus prompt, they may be used as links in larger chains. (Ex. teach hand washing, tooth brushing, and showering until mastered and then teach morning hygiene routine which includes the mastered skills). Chaining requires that the teachers present the training skill in the same order each time and is most effective when teachers are delivering the same prompts to the learner. The most common forms of chaining are backward chaining, forward chaining, and total task presentation.

More on Chaining

There are two different types of chains: homogeneous and heterogeneous. The prior homogeneous chains occur when the topography or form of response are similar in each component. While in heterogeneous chain requires different responses for each link.^[1]
