sign

1. Maths logica. any symbol indicating an operation b. the positivity or negativity of a number, quantity, or expression 2. an indication, such as a scent or spoor, of the presence of an animal 3. Med any objective evidence of the presence of a disease or disorder 4. Astrology See sign of the zodiac

sign

  1. any direct indicator of an occurrence, e.g. the appearance of spots is a sign of measles (natural signs).
  2. any SYMBOL, including the written marks for words, which stands for – or represents – both a meaning and an external thing which ‘corresponds’ to the meaning. Taking an ‘empiricist’ view, there is a sense in which signs ‘picture’ an external reality (see EMPIRICISM).
  3. (modern LINGUISTICS and STRUCTURALISM) any signifier which signifies a concept or ‘meaning’, the signified. In this view, the relation between the SIGNIFIER and SIGNIFIED is internal to a particular language (see also LANGUE AND PAROLE, SAUSSURE).
As emphasized in SEMIOLOGY (OR SEMIOTICS), the general theory of signs, signs may take many forms, including icons (pictures), dress, conspicuous social display, etc. – thus ‘referents’ also signify – and all such signs are amenable to analysis in structural terms, i.e. as a system of ’DIFFERENCES’.

Compared with sense 1 (natural signs), senses 2 and 3 involve ‘arbitrary’ rather than natural signs. Sense 2 in particular, that our ability to refer depends on internal ‘differences’, also emphasizes that linguistic structures (at least the semantic structures) are 'social’ not biological or individual in form (see also WITTGENSTEIN, FORMS OF LIFE, PARADIGM). Sense3 is also central in modern POST-EMPIRICIST and POST-STRUCTURALIST thinking in philosophy, leading to celebrations or accusations of ‘loss of reference’- see RELATIVISM, INCOMMENSURABILITY. But an emphasis on the ‘internal relations’ of sign systems need not imply lack of reference, merely that any system of reference cannot be guaranteed (see also FEYERABEND, KUHN). See also SEMANTICS, BODY LANGUAGE, METAPHOR.

Sign

 

a material object (phenomenon, event) that represents another object, property, or relation and is used to acquire, store, process, and transmit messages (information, knowledge).

Linguistic (belonging to a system of signs) are distinguished from nonlinguistic signs. Nonlinguistic signs are divided into copy signs, indicator signs, and symbol signs. Copy signs are reproductions, more or less similar to that which is being denoted, such as photographs, fingerprints, and, to a certain extent, pictographic writing. Indicator signs are signs associated with denoted objects as effects with causes (sometimes referred to as symptoms or indices). Symbol signs are signs that, as a result of graphic images contained in them, are used to express a particular content, frequently extremely meaningful and abstract (for example, a picture of the ancient Greek theatrical mask as a symbol for modern theater; the term “symbol” is also used as an equivalent for “sign”).

Linguistic signs do not function independently of each other. They form a system, whose rules determine the regularities of their combination (rules of grammar, or syntax in a broad sense), comprehension (rules of meaning, or significance, of a symbol), and use. If a language serves as a means of communication in society, signs entering into its structure are referred to as communicative signs. These are divided into signs of natural languages and signs of artificial sign systems (artificial languages). Signs of natural languages (individual words, expressions with proper grammatical structure, sentences) include both sound signs and the corresponding handwritten and typographic signs. Nonlinguistic signs play an auxiliary role in communication. In natural communicative languages—national languages—only rules of grammar exist in more or less explicit form; rules of meaning and use are not explicitly formulated. The development of science has led to the introduction into natural languages of special graphic signs used to abbreviate scientific concepts and propositions and methods of operating with objects being studied in science (such as systems of mathematical, astronomical, and chemical symbols). Artificial languages, whose rules (at least the rules of syntax and meaning) are explicitly formulated, are fashioned from such signs. Artificial languages are used primarily in science, where they serve not only as a means of communication between scientists and scientific bodies but as a means of obtaining new information about phenomena being studied. Signs of artificial sign systems include the signs of code systems designed for coding ordinary speech or for receding previously coded messages (for example, Morse code and codes used in formulating programs for digital computers); signs for simulating continuous processes (for example, curves representing continuous changes in certain processes); and signs from which formulas used in scientific languages (including signs of formal systems and those of logical information systems) are constructed, the most important variety of signs used in science. A distinction is generally made between signs whose significance (meaning) does not depend on other signs (so-called natural signs proper) and nonproper signs, which do not have their own signifying character but only aid in forming complex signs from simpler ones (for example, brackets).

The denotational, semantic, and expressive meanings of a sign are distinguished. A sign is said to represent a given object (or objects)—the object represented by a sign is referred to as its denotational meaning—and to express its semantic and expressive meanings. The semantic meaning (sense) of a sign serves to identify its denotational meaning— that is, to single out the object represented by a sign (although there may be signs having only a semantic meaning but not representing any object, such as the expression “mermaid”). On the other hand, there may be signs in which the semantic meaning has been reduced to a minimum. Proper nouns of natural languages are a case in point. The semantic meaning of a sign is its capacity to represent and register aspects, features, and properties of the denoted object that define the sphere of applications of the sign; it is that which man understands when perceiving or reproducing a given sign. In science the semantic meaning of a sign takes the form of a notion. In a number of fields (especially mathematics) objects represented by signs (by expressions of a corresponding scientific language) represent ideal, abstract units. The feelings and desires of man expressed by means of a given sign (in its use in a given context and in a given situation) are understood as the expressive meaning of a sign. Natural spoken language is extremely expressive, but in written scientific language most expressions (and in formal languages, all expressions) are devoid of expressive meaning. On the other hand, there are linguistic signs that strictly speaking have no meaning other than the expressive; such is the case, for example, with interjections.

The formation of mankind itself, as well as fundamental turning points in the development of science (for example, the emergence of mathematical symbolics in the 16th and 17th centuries, which sharply accelerated the progress of mathematics and its application in mechanics, astronomy, and physics; and the development of formal indexing, machine, and similar languages linked with cybernetics), has been linked to the development of the capacity to extract and process information about objects by working directly not with the objects themselves but with signs representing them. The creation of special symbolics and, especially, of systems of formulas generally reveals new potentials in science. Rationally constructed systems of signs make it possible to express in visible form interrelationships between the phenomena being studied, to achieve nonambiguity of terms, and to denote notions for which there are no verbal expressions in ordinary language. Formulas frequently express both the end result and the means of obtaining such a result. The recording of messages with the help of signs makes possible the transmission of information through technical communication channels and its diverse—mathematical, statistical, and logical—processing by means of automated devices (logical information machines and control systems, including digital computers).

sign

[sīn] (communications) In semiotics, an entity that signifies some other thing, and may be interpreted. (mathematics) A symbol which indicates whether a quantity is greater than zero or less than zero; the signs are often the marks + and - respectively, but other arbitrarily selected symbols are used, especially in automatic data processing. A unit of plane angle, equal to 30° or π/6 radians.

sign, signboard

1. A display board or surface used for directions, identification, instructions, or advertising; usually consists of lettering, pictures, diagrams, decoration, etc., often in combination, on a contrasting background surface. 2. According to OSHA: a warning of hazard, temporarily or permanently affixed or placed, at a location where a hazard exists.

sign

A symbol that identifies a positive or negative number. In digital form, it is either a separate character or part of the byte. In ASCII, the sign is kept in a separate character typically transmitted in front of the number it represents
(+ and - is 2B and 2D in hex).

In EBCDIC, the minus sign can be stored as a separate byte (hex 60), or, more commonly, as half a byte (+ and - is C and D in hex), which is stored in the high-order bits of the least significant byte. For packed decimal, it is in the low-order bits of the least significant byte.

sign convention A set of conventions regulating the direction of distances, lengths, and angles measured in geometrical optics. The most common is the New Cartesian Sign Convention. It stipulates: (1) All distances are measured from the lens, refracting surface or mirror. Those in the same direction as the incident light, which is drawn travelling from left to right, are positive. Those in the opposite direction are negative. (2) All distances are measured from the axis. Those above are positive. Those below are negative. (3) Angles are measured from the incident ray to the axis, with anticlockwise angles positive and clockwise angles negative. (4) The power of a converging lens is positive and that of a diverging lens is negative (Fig. S7). See focal length; Lagrange's law; law of refraction; Newton's formula; fundamental paraxial equation.
Dalrymple's sign Retraction of the eyelids causing an abnormally widened palpebral fissure, in primary gaze. This is a sign of Graves' disease. The patient appears to stare and to be frightened as some white sclera may be seen above the upper limbus.

Sign


sign

v. 1) to write one's signature on a document, including an "X" by an illiterate or physically impaired person, provided the mark is properly witnessed in writing as "Eddie Jones, his mark." An attorney-in-fact given authority to act for another person by a power of attorney may sign for the one giving the power, but should identify the signature as "by his attorney-in-fact, George Goodman." 2) to communicate by sign language. (See: mark, subscribe)

SIGN, contracts, evidence. A token of anything; a note or token given without words.
2. Contracts are express or implied. The express are manifested viva voce, or by writing; the implied are shown by silence, by acts, or by signs.
3. Among all nations find and at all times, certain signs have been considered as proof of assent or dissent; for example, the nodding of the head, and the shaking of hands; 2 Bl. Com. 448; 6 Toull. D. 33; Heinnec., Antiq. lib. 3, t. 23, n. 19; silence and inaction, facts and signs are sometimes very strong evidence of cool reflection, when following a question. I ask you to lend me one hundred dollars, without saying a word you put your hand in your pocket, and deliver me the money. I go into a hotel and I ask the landlord if he can accommodate me and take care of my trunk; without speaking he takes it out of my hands and sends it into his chamber. By this act he doubtless becomes responsible to me as a bailee. At the expiration of a lease, the tenant remains in possession, without any objection from the landlord; this may be fairly interpreted as a sign of a consent that the lease shall be renewed. 13 Serg. & Rawle, 60.
4, The learned author of the Decline and Fall of the Roman Empire, in his 44th chapter, remarks, "Among savage nations, the want of letters is imperfectly supplied by the use of visible signs, which awaken attention, and perpetuate the remembrance of any public or private transaction. The jurisprudence of the first Romans exhibited the scenes of a pantomime; the words were adapted to the gestures, and the slightest error or neglect in the forms of proceeding was sufficient to annul the substance of the fairest claim. The communion of the marriage-life was denoted by the necessary elements of fire and water: and the divorced wife resigned, the bunch of keys, by the delivery of which she had been invested with the government of the family. The manumission of a son, or a slave, was performed by turning him round with a gentle blow on the cheek: a work was prohibited by the casting of a stone; prescription was interrupted by the breaking of a branch; the clenched fist was the symbol of a pledge or deposits; the right hand was the gift of faith and confidence. The indenture of covenants was a broken straw; weights and, scales were introduced into every payment, and the heir who accepted a testament, was sometimes obliged to snap his fingers, to cast away his garments, and to leap and dance with real or affected transport. If a citizen pursued any stolen goods into a neighbor's house, he concealed his nakedness with a linen towel, and hid his. face with a mask or basin, lest he should encounter the eyes of a virgin or a matron. In a civil action, the plaintiff touched the ear of his witness seized his reluctant adversary by the neck and implored, in solemn lamentation, the aid of his fellow citizens. The two competitors grasped each other's hand, as if they stood prepared for combat before the tribunal of the praetor: he commanded them to produce the object of the dispute; they went, they returned with measured steps, and a clod of earth was cast at his feet to represent the field for which they contended. This occult science of the words and actions of law, was the inheritance of the pontiffs and patricians. Like the Chaldean astrologers, they announced to their clients the days of business and repose; these important trifles wore interwoven with the religion of Numa; and, after the publication of the Twelve Tables, the Roman people were still enslaved by the ignorance of judicial proceedings. The treachery of some plebeian officers at length revealed the profitable mystery: in a more enlightened age, the legal actions were derided and observed; and the same antiquity which sanctified the practice, obliterated the use and meaning, of this primitive language."

SIGN, measures. In angular measures, a sign is equal to thirty degrees. Vide Measure.

SIGN, mer. law. A board, tin or other substance, on which is painted the name and business of a merchant or tradesman.
2. Every man has a right to adopt such a sign as he may please to select, but he has no right to use another's name, without his consent. See Dall. Dict. mot Propriete Industrielle, and the article Trade marks.

TO SIGN. To write one's name to an instrument of writing in order to give the effect intended; the name thus written is called a signature.
2. The signature is usually made at the bottom of the instrument but in wills it has been held that when a testator commenced his will With these words;, "I, A B, make this my will," it was a sufficient signing. 3 Lev. 1; and vide Rob. on Wills, 122 1 Will. on Wills, 49, 50; Chit. Cont. 212 Newl. Contr. 173; Sugd. Vend. 71; 2 Stark. Ev. 605, 613; Rob. on Fr. 121; but this decision is said to be absurd. 1 Bro. Civ. Law, 278, n. 16. Vide Merl. Repert. mot Signature, for a history of the origin, of signatures; and also 4 Cruise, Dig. h.t. 32, c. 2, s. 73, et seq.; see, generally, 8 Toull. n. 94-96; 1 Dall. 64; 5 Whart. R. 386; 2 B. & P 238; 2 M. & S. 286.
3. To sign a judgment, is to enter a judgment for want of something which was required to be done; as, for example, in the English practice, if he who is bound to give oyer does not give it within the time required, in such cases, the adverse party may sign judgment against him. 2 T. R. 40; Com. Dig. Pleader, P 1; Barnes, 245.
