Although explicit and implicit knowledge of language learners are essential to theoretical and pedagogical debates in second language acquisition (SLA), little research has addressed the effects of instructional interventions on the two knowledge types (R. Ellis, 2005).This study examined the relative effectiveness of explicit and implicit types of form-focused instruction (FFI) on the acquisit...

Ultrafast vortex motion has recently become a subject of extensive investigations, triggered by the fundamental question regarding ultimate speed limits for magnetic flux quanta and enhancements single-photon detectors. In this regard, current-biased quench dynamic flux-flow regime---flux-flow instability (FFI)---has turned into widely used method extraction information about relaxation quasipa...

This paper examines a class of economies with externalities, strategic complementarity or substitutability, and incomplete information. We first characterize efficient allocations and compare them to equilibrium. We show how the optimal degree of coordination and the efficient use of information depend on the primitives of the environment, and how this relates to the welfare losses due to volat...

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....

BACKGROUND Open reduction with internal fixation (ORIF) and percutaneous surgery (PS) are the most common surgical procedures for the treatment of displaced intra-articular calcaneal fractures. The purpose of this retrospective study was to compare the clinical and radiological results of these techniques and to verify the prognostic value of the radiographic measurement tools proposed in the l...

The objectives of this study were to evaluate heat stress feed intake models for growing swine using a data set assembled from the literature and to develop a series of new equations modeling the influence of the thermal environment and interactions between the thermal environmental and other factors on feed intake. A literature survey was conducted to identify studies assessing intake response...

A method is presented for determining the local magnitude, NIL, from records from seismoscopes and similar instruments. The technique extrapolates the maximum response of the standard Wood-Anderson seismograph, which determines ML, from the maximum response of the seismoscope. The standard deviation of the steady-state response of an oscillator subjected to white noise excitation is used to der...
