Data mining is the discovery of knowledge and useful information from the large amounts of data stored in databases. The emerging data mining tools and systems lead to the demand of a powerful data mining query language. The concepts of such a language for relational databases are discussed in [11].

Aspect-oriented programming (AOP) is an emerging technique that provides a mechanism to clearly encapsulate and implement concerns that crosscut other modules. It is claimed that this technique improves code modularization and therefore reduces complexity of object-oriented programs (OOP). Most of the proposed complexity measurement frameworks for AOP are for AspectJ programming language. In th...

This study examined the effects of input-oriented and output-oriented tasks with different involvement load indices on Iranian EFL learners' comprehension and production of lexical collocations.

Each of the groups was random...

Of the many dilemmas facing the assessment of literary competence, one is the extent to which language should constitute part of the target construct intended to be measured. Some argue for the construct-irrelevance of language and hence recommend that it be eliminated or minimized in favor of an exclusive focus on literary competence. In practice, this does not seem to be the case, as language...
