Metapredicativity is a new general term in proof theory which describes the analysis and study of formal systems whose proof-theoretic strength is beyond the Feferman-Schütte ordinal Γ0 but which are nevertheless amenable to purely predicative methods. Typical examples of formal systems which are apt for scaling the initial part of metapredicativity are the transfinitely iterated fixed point th...

Collaborative filtering (CF) has been one of the most important and popular recommendation methods, which aims at predicting users’ preferences (ratings) based on their past behaviors. Recently, various types side information beyond explicit ratings users give to items, such as social connections among metadata have introduced into CF shown be useful for improving performance. However, previous...

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...

Biometric based authentication protocols for multi-server architectures have gained momentum in recent times due to advancements in wireless technologies and associated constraints. Lu et al. recently proposed a robust biometric based authentication with key agreement protocol for a multi-server environment using smart cards. They claimed that their protocol is efficient and resistant to promin...

The cerebellum is organized into parasagittal zones with respect to the topography of climbing fiber (CF) afferents and the expression of molecular markers such as zebrin II. Zebrin is expressed by a subset of Purkinje cells that are distributed as a parasagittal array of immunopositive and immunonegative stripes. Several studies in rodents suggest that, in general, CFs to the zebrin negative s...

this study is a typological description of written formative feedback in an efl context in iran. twenty m.a. students of tefl participated in the study. they were required to summarize a scholarly article in each session on which the instructor would provide written corrective feedback (cf). written formative comments were extracted, coded, and categorized into various types, such as asking for...
