Despite the general findings that address the positive contribution of teaching pragmatic features to interlanguage pragmatic development, the question as to the most effective method is far from being resolved. Moreover, the potential of literature as a means of introducing learners into the social practices and norms of the target culture, which underlie the pragmatic competence, has not been...

Measuring the quality of recommendations produced by a recommender system (RS) is challenging. Labels used for evaluation are typically obtained from users of a RS, by asking for explicit feedback, or inferring labels from implicit feedback. Both approaches can introduce significant biases in the evaluation process. We investigate biases that may affect labels inferred from implicit feedback. I...

Based on a group of new Saul’yev type asymmetric difference schemes constructed by author, a high-order, unconditionally stable and parallel alternating segment explicit-implicit method for the numerical solution of the fourth-order heat equation is derived in this paper. The truncation error is fourth-order in space, which is much more accurate than the known alternating segment explicit-impli...

Visuomotor adaptation has been thought to be an implicit process that results when a sensory-prediction error signal is used to update a forward model. A striking feature of human competence is the ability to receive verbal instructions and employ strategies to solve tasks; such explicit processes could be used during visuomotor adaptation. Here, we used a novel task design that allowed us to o...

Despite the increasing popularity of error treatment as a research subject, the effect of age as a potential learner-internal factor affecting choice of feedback is largely undertreated. Characterized by being at early stages of self-empowerment, young language learners are considerably vulnerable and in need of particular language input to meet their age-appropriate psychological demands. This...

The concept of social search has been acquiring importance in the WWW as large-scale collaborative computing environments have become feasible.This field focuses on the reader’s perspective in order to assign relevance and trustworthiness to web pages. Although current web searching technologies tend to rely on explicit human recommendations, these techniques are hard to scale as feedback is ha...

Recommender systems typically require feedback from the user to learn the user’s taste. This feedback can come in two forms: explicit and implicit. Explicit feedback consists of ratings provided by the user for a number of items, while implicit feedback comes from observing user actions on items. These actions have to be interpreted by the recommender system and translated into a rating. In thi...

The convergence of an alternating direction implicit method for Maxwell’s equations on product domains is investigated. Unlike the classical Yee scheme and most other integrators proposed in the literature, this method is both unconditionally stable and computationally cheap. We prove second-order convergence of the time-discretization in the framework of operator semigroup theory. In contrast ...
