Mode (computer interface)

In user interface design, a mode is a distinct setting within a computer program or any physical machine interface, in which the same user input will produce perceived different results than it would in other settings. The best-known modal interface components are probably the Caps lock and Insert keys on the standard computer keyboard, both of which put the user's typing into a different mode after being pressed, then return it to the regular mode after being re-pressed.

An interface that uses no modes is known as a modeless interface. Modeless interfaces intend to avoid mode errors by making it impossible for the user to commit them.

Definition

A precise definition is given by Jef Raskin in his book The Humane Interface:

"An human-machine interface is modal with respect to a given gesture when (1) the current state of the interface is not the user's locus of attention and (2) the interface will execute one among several different responses to the gesture, depending on the system's current state." (Page 42).

Mode (literature)

In literature, a mode is an employed method or approach, identifiable within a written work. As descriptive terms, form and genre are often used inaccurately instead of mode; for example, the pastoral mode is often mistakenly identified as a genre. The Writers Web site feature, A List of Important Literary Terms, defines mode thus:

History of mode

In his Poetics, the ancient Greek philosopher Aristotle uses 'mode' in a more specific sense. Kinds of 'poetry' (the term includes drama, flute music, and lyre music for Aristotle), he writes, may be differentiated in three ways: according to their medium of imitation, according to their objects of imitation, and according to their mode or 'manner' of imitation (section I). "For the medium being the same, and the objects the same, the poet may imitate by narration—in which case he can either take another personality as Homer does, or speak in his own person, unchanged—or he may present all his characters as living and moving before us" (section III). According to this definition, 'narrative' and 'dramatic' are modes of fiction:

Mode (music)

In the theory of Western music, mode (from Latin modus, "measure, standard, manner, way, size, limit of quantity, method") (Powers 2001, Introduction; OED) generally refers to a type of scale, coupled with a set of characteristic melodic behaviours. This use, still the most common in recent years, reflects a tradition dating to the Middle Ages, itself inspired by the theory of ancient Greek music.

Mode as a general concept

Regarding the concept of mode as applied to pitch relationships generally, Harold S. Powers proposed mode as a general term but limited for melody types, which were based on the modal interpretation of ancient Greek octave species called tonos (τόνος) or harmonia (ἁρμονία), with "most of the area between ... being in the domain of mode" (Powers 2001, §I,3). This synthesis between tonus as a church tone and the older meaning associated with an octave species was done by medieval theorists for the Western monodic plainchant tradition (see Hucbald and Aurelian). It is generally assumed that Carolingian theorists imported monastic Octoechos propagated in the patriarchates of Jerusalem (Mar Saba) and Constantinople (Stoudios Monastery) which meant the eight echoi they used for the composition of hymns (e.g., Wellesz 1954, 41 ff.), though direct adaptations of Byzantine chants in the survived Gregorian repertoire are extremely rare.

Formal language

In mathematics, computer science, and linguistics, a formal language is a set of strings of symbols that may be constrained by rules that are specific to it.

The alphabet of a formal language is the set of symbols, letters, or tokens from which the strings of the language may be formed; frequently it is required to be finite. The strings formed from this alphabet are called words, and the words that belong to a particular formal language are sometimes called well-formed words or well-formed formulas. A formal language is often defined by means of a formal grammar such as a regular grammar or context-free grammar, also called its formation rule.

The field of formal language theory studies primarily the purely syntactical aspects of such languages—that is, their internal structural patterns. Formal language theory sprang out of linguistics, as a way of understanding the syntactic regularities of natural languages. In computer science, formal languages are used among others as the basis for defining the grammar of programming languages and formalized versions of subsets of natural languages in which the words of the language represent concepts that are associated with particular meanings or semantics. In computational complexity theory, decision problems are typically defined as formal languages, and complexity classes are defined as the sets of the formal languages that can be parsed by machines with limited computational power. In logic and the foundations of mathematics, formal languages are used to represent the syntax of axiomatic systems, and mathematical formalism is the philosophy that all of mathematics can be reduced to the syntactic manipulation of formal languages in this way.

Language (journal)

Language is a peer-reviewed quarterly academic journal published by the Linguistic Society of America since 1925. It covers all aspects of linguistics, focusing on the area of theoretical linguistics. Its current editor-in-chief is Gregory Carlson (University of Rochester).

Under the editorship of Yale linguist Bernard Bloch, Language was the vehicle for publication of many of the important articles of American structural linguistics during the second quarter of the 20th century, and was the journal in which many of the most important subsequent developments in linguistics played themselves out.

One of the most famous articles to appear in Language was the scathing 1959 review by the young Noam Chomsky of the book Verbal Behavior by the behaviorist cognitive psychologist B. F. Skinner. This article argued that Behaviorist psychology, then a dominant paradigm in linguistics (as in psychology at large), had no hope of explaining complex phenomena like language. It followed by two years another book review that is almost as famous—the glowingly positive assessment of Chomsky's own 1957 book Syntactic Structures by Robert B. Lees that put Chomsky and his generative grammar on the intellectual map as the successor to American structuralism.

Lak language

The Lak language (лакку маз, lakːu maz) is a Northeast Caucasian language forming its own branch within this family. It is the language of the Lak people from the Russian autonomous republic of Dagestan, where it is one of six standardized languages. It is spoken by about 157,000 people.

History

In 1864 Russian ethnographer and linguist P. K. Uslar wrote: "Kazikumukh grammar or as I called it for short in the native language, the Lak grammar, Lakku maz, the Lak language, is ready".

In 1890 a textbook was published on Lak grammar compiled by P.K. Uslar named as The Lak Language. It stated under the title "Lak alphabet": "The proposed alphabet is written for people who name themselves collectively Lak, genitive Lakral. From among these people each one is named separately Lakkuchu 'Lakian man,' the woman — Lakkusharssa 'Lakian woman.' Their homeland they name Lakral kIanu — 'Lak place.'"

Lak has throughout the centuries adopted a number of loanwords from Arabic, Turkish, Persian, and Russian. Ever since Dagestan was part of the USSR and later Russia, the largest portion of loanwords have come from Russian, especially political and technical vocabulary. There is a newspaper and broadcasting station in Lak language.
