Noticing that some recent variations of descent polynomials are special cases Carlitz and Scoville's four-variable polynomials, which enumerate permutations by the parity ascent positions, we prove a q-analogue Carlitz-Scoville's generating function counting inversion number type B analogue enumerating signed with respect to positions. As by-product our formulas, obtain Chebikin's formula for a...

We present Submatrix-wise Vector Embedding Learner (Swivel), a method for generating lowdimensional feature embeddings from a feature co-occurrence matrix. Swivel performs approximate factorization of the point-wise mutual information matrix via stochastic gradient descent. It uses a piecewise loss with special handling for unobserved co-occurrences, and thus makes use of all the information in...

Recasts are an important type of implicit negative feedback that has attracted much attention in both L1 research and SLA research. The utility of recasts in face-to-face interaction has been empirically established, and the contingency of recasts is argued to be the key. However, the efficacy of recasts in computer-mediated communication (CMC), text-based online chatting in particular, remains...

This study investigated whether eye-tracking technology could be employed as a measure of noticing of corrective feedback (in the form of explicit recasts) during NS-NNS taskbased synchronous computer-mediated communication (SCMC). Pairs of university-level learners of English (n = 18) engaged in a short chat interaction task with a native speaker, who provided intensive and explicit corrective...

This research advances notions about how interactive learning environments that intentionally shape learners’ identities can empower students and give them agency. Our work draws on teacher noticing, extends it to the community level, orients towards identity. We provide an instrumental case study approach examines community-identity noticing within a long term design-based project around human...

Abstract This is a story about the ‘arts of noticing’ more‐than‐human noticing. In it I reflect on ways in which my own practice ethnographic filmmaking itself an agent multisensory participation. As artifice and artificial eye, there something both liberating sensuous practice. It heightens performativity participants their embodied rituals allows me to enter intimate spaces would otherwise no...

BACKGROUND One of the stakeholders in tackling the rise and health consequences of overweight and obesity is the general practice physician (GP). GPs are in a good position to inform and give nutrition guidance to overweight patients. OBJECTIVE Assessment of working mechanism of determinants of the nutrition guidance practice: noticing patients' overweight and guidance of treatment by GPs [li...
