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 tests....

A theorem of Laman gives a combinatorial characterisation of the graphs that admit a realisation as a minimally rigid generic bar-joint framework in R. A more general theory is developed for frameworks in R whose vertices are constrained to move on a two-dimensional smooth submanifold M. Furthermore, when M is a union of concentric spheres, or a union of parallel planes or a union of concentric...

We provide a bound on the size of simultaneous best response cycles for generic finite two-player games. The bound shows that no cycle will move through the entire strategy space as long as either player has more than two strategies. This bound increases quadratically in the size of the strategy spaces. It is the tightest possible in the sense that we can construct a generic game with a cycle t...

Abstract Abstract Background: Availability and affordability of medicines are crucial to achieving success in prevention programs, particularly in developing countries. Objective: The aim of this study was to determine the availability and affordability of cardiovascular medicines for secondary prevention in Tehran province of Iran.

communicative moves and lexical cohesion patterns (lcps), as mounting evidence shows, are two important indicators in writing and publishing the ras. however, the interaction between these two crucial elements and the contribution of this interaction to the failure or success of the ras have not been given due attention to date. having this in mind and based on a sound theoretical framework, at...

the notion of genre has received a great deal of attention both in discourse analytic studies as well as in the field of esp/eap course design. the present paper has attempted to use genre analysis to account for the rhetorical features of research article introductions written by iranian academics in two disciplinary fields of education and economics. the corpus comprised 40 research article i...
