... The Byzantine monastic habit, the taking of which was equivalent to entry into monastic life. Originally there was only one schèma . From the 8th c., it became customary to distinguish a little schèma , consisting of a black robe and a cross , for ordinary monks, and a great schèma , consisting in addition of a cowl and scapular , for more “perfect” monks. Certain monks ( Theodore the Studite, Gregory Palamas ) denounced this practice, saying that there was only one monastic vocation just as there was only one baptism . Other authors (Balsamon, ...

... are established. The use of schema implies there are generalized motor programmes for a given class of movement. It is proposed that the schema would not take up much storage space (storage is a problem with theories positing a one-to-one relationship between stored programmes and generated movements) and would help explain the ability to perform relatively novel tasks. When acquiring a new skill or competing in a game, a performer recalls and adapts the schema to suit a particular situation, and carry out the required movements. Schema are constructed...

In perception , schemata assist interpretation but assimilation can also lead to distortion ( see levelling and sharpening ). Schemata facilitate cognitive processes such as the generation of inferences and ...

... As understood in current early childhood pedagogy , a schema is ‘a pattern of repeatable behaviour into which experiences are assimilated and that are generally co-ordinated’ ( Athey 1990 ). Piaget first identified repeated behaviours as skills, which, once assimilated, are transferred to other activities and adapted, if necessary, to satisfy a child’s drive to learn and succeed. An example of this might be the action of a push-button mechanism which activates sound or pictures. Once the child has learned this behaviour, this will be repeated when...

(σχη̑μα, lit. “form, shape”), the habit of monks and nuns, which took two forms: the mikron schema , or “lesser habit,” and the mega schema (or angelikon schema ), the “greater habit,” which symbolized the highest level of monastic profession. The monastic costume of the megaloschemos monk was differentiated from that of the mikroschemos by the koukoulion (cowl) and analabos (scapular). The distinction between mikroschemoi (or staurophoroi ) and megaloschemoi monks is first mentioned in the Diatheke of Theodore of Stoudios , who...

... . Literally shape, pattern, form; plural, schemata or schemas. In logic a schema is an expression, often a sentence, from which certain word-groups have been removed and replaced by blanks or more commonly by ‘schematic letters’, the role of these being to mark places where any word-group of the type removed can be inserted: e.g. ‘ P ’, ‘ F ’, ‘ G ’ in ‘If not P , P ; therefore P ’, ‘ G belongs to some F ’, ‘∃ x ( Fx ∧ Gx )’ (‘Something is F and G ’). Some schemata are formulae , i.e. contain no words. But there are also formulae with meanings,...

... ( pl. schemata ) In many logical calculi , axioms and rules are presented as forms or schemata, with the provision that any of an infinite number of substitution instances are axioms. For example, the rule of inference modus ponens may be presented as A; A → B, so B, where A and B can be substituted by any well-formed formula of the calculus. Statements that are intuitively framed by talking of all functions, all properties, etc., such as Peano’s fifth postulate, or the set-theoretic axioms of separation and replacement , are represented by axiom...

In Plutarch's treatise, deixis may mean “pointing,” “indication,” or even “portrayal”; phora may be translated as “motion” or “carriage”; and schēma as “posture,” “gesture,” or “figure,” among other possibilities. The overlapping and elusive meanings of his terms have confused modern scholars who have interpreted the essay as a technical analysis rather than as a philosophical inquiry.

...schema A formalized description of the structure of an XML document. XML schemas serve the same purpose as DTDs but are much more powerful and flexible. For example, a single document may use namespaces to take element definitions from more than one schema, with each element being validated against the appropriate schema. Schemas also allow element content to be restricted to specified data types (string, boolean, decimal number, etc.). Although the World Wide Web Consortium has issued a specification for XML schemas, other schema languages are also...
