The response of an animal to antigen is altered after its first exposure. The intensified secondary response has been attributed by some to the presence of qualitatively different "memory" cells. The concept of two types of antigen-sensitive ceils, occurring as successive stages in immunoeyte maturation, was elaborated by Burner (i) and Leduc et al. (2), and later into an X-Y-Z scheme by Sercar...

Second Language Comprehensibility Revisited: Investigating the Effects of Learner Background Dustin Crowther The current study investigated first language (L1) effects on listener judgment of comprehensibility and accentedness in second language (L2) speech. The participants were 60 university-level adult speakers of English from four L1 backgrounds (Chinese, Romance, Hindi, Farsi), with 15 spe...

CpG islands are genome subsequences with an unexpectedly high number of CG di-nucleotides. They are typically identified using filtering criteria (e.g., G+C% expected vs. observed CpG ratio and length) and are computed using sliding window methods. Most such studies illusively assume an exhaustive search of CpG islands are achieved on the genome sequence of interest. We devise a Lexis diagram a...

This article is a contribution to theory of lexical semantics and situated sense-making which aims at explaining how meaning constituted in across contexts, dialogical interplay between resources aspects situations. We propose that the words or grammatical constructions are not just abstract schemas, be filled by pragmatic enrichment uses. Nor associated with simple lists different usages. Inst...

Increasing migration is a vital concern for a globalizing sociocultural environment in today’s world. The UK and developed European countries have become an attractive destination for asylum seekers (labelled as “migrants”) in the past decade. The rapid rise in the number of asylum seekers, which was labelled “migration crisis” (Ruz, 2015), made this topic an integral part of scientific discuss...

In the systemic framework, lexis has received little attention in comparison to grammar. The paper compares existing systemic approaches to lexis and outlines a model for describing lexical items from the viewpoint of realization of communicative intentions by lexical items using the systemic network of lexical choices. As an example of the approach, the paper attempts to describe contrastive l...
