this study investigated the relative effects of deductive and inductive form-focused instruction (ffi) on the acquisition of 4 non-generic definite article uses(cultural, situational, structural, and textual) as assessed by explicit and implicit outcome measures. the tests utilized to assess efl learners' acquisition of definite article uses were timed and untimed grammaticality judgment t...

An asynchronous unit delay is an n input n output of the input n-tuple prior to the last inlput change. It asynchronous sequential circuit in which the present value of the will then be shown that every asynchronous definite flow output n-tuple is equal to the value of the input n-tuple prior to the last input change. This paper considers the problem of determining ablecan brizeday a fee bac r ...

We present a partial proof of van Hoeij-Abramov conjecture about the algorithmic possibility of computation of finite sums of rational functions. The theoretical results proved in this paper provide an algorithm for computation of a large class of sums (1).

What happens when the description is improper? A description νΦ is proper if there is exactly-one entity such that Φ [in the relevant situation]; otherwise, it is improper. We propose to treat improper descriptions as non-starters, which vitiate every expression in which they appear. In particular, an improper description is null [i.e., denotes nothing], and every expression in which it appears...

In this paper it is shown that a definite description refers to a given discourse referent if the descriptive content is deaccented. But if there is an accent on the descriptive content, a novel referent is introduced. Starting from a uniqueness view of definiteness, a distinction between two uses of definite descriptions is proposed: ‘Given definites’ represent identity anaphors exploiting the...

We study the problem of manifold alignment, which aims at “aligning” different data sets that share a similar intrinsic manifold provided some supervision. Unlike traditional methods that rely on pairwise correspondences between the two data sets, our method only needs some relative comparison information like “A is more similar to B than A is to C”. This method provides a more flexible way to ...

Since Heubner's (1985) pioneering study, there have been many studies on (mis) use/ non-use of articles by L2 learners from article-less and article languages. The present study investigated how Persian L2 learners of English produce and interpret English definite descriptions and demonstrative descriptions. It was assumed that definite and demonstrative descriptions share the same central sema...
