OBJECTIVE To evaluate the effects of recasting on the biocompatibility of a commercially available Ni-Cr alloy. METHODS The alloy tested was cast and subsequently recast four more times. For each cast condition, 24 disk shaped specimens were fabricated (5 mm in diameter, 0.5 mm in thickness). All the recasting was performed without adding new alloy. After the first cast and following each rec...

Based on the controversial beliefs among L2 teachers about effective corrective feedback (CF) strategies, recast and prompts as 2 kinds of CF have drawn the attention of L2 researchers(e.g., Braidi, 2002; Iwashita, 2003; Loewen & Philp, 2006; Panova & Lyster, 2002; Sheen, 2004). Despite these numbers of studies, debate continues to exist about their usefulness as a CF technique. Whereas recasts...

Much thought has been accorded to the evolving nature of business history. It is only relatively recently, however, that attempts have made articulate methodological issues in a more epistemologically explicit and reflexive fashion. This article contributes this burgeoning agenda by examining methodology underpinning an intensive archival study British interwar management movement (1918–1939), ...

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...

We recast dataflow in a modern categorical light using profunctors as a generalization of relations. The well known causal anomalies associated with relational semantics of indeterminate dataflow are avoided, but still we preserve much of the intuitions of a relational model. The development fits with the view of categories of models for concurrency and the general treatment of bisimulation the...

Semantic composition remains an open problem for vector space models of semantics. In this paper, we explain how the probabilistic graphical model used in the framework of Functional Distributional Semantics can be interpreted as a probabilistic version of model theory. Building on this, we explain how various semantic phenomena can be recast in terms of conditional probabilities in the graphic...

We present here the transformations required to recast the Robertson-Walker metric and Friedmann-Robertson-Walker equations in terms of observer-dependent coordinates for several commonly assumed cosmologies. The overriding motivation is the derivation of explicit expressions for the radius R h of our cosmic horizon in terms of measurable quantities for each of the cases we consider. We show th...
