Vocabulary can change quickly as new words are borrowed from other languages, or as words get combined or shortened. Information and communication technologies （ICT） are one of the major driving forces in the process of globalization. This paper focuses on some lexicon changes over the last two decades. In particular, affixation, compounding, blending, and meaning shift are illustrated in detail.展开更多

To start, I will briefly explain what meaning eliminativism is and illustrate the key arguments that have been offered in its defense. Then, I will argue that such arguments are not as persuasive as they wish, and I will show that there are convincing theoretical and empirical reasons to maintain that meaning eliminativism is not a plausible claim about the nature of our lexical skills.展开更多

In this paper, Herrera-Martfnez＇s 2-Tuple linguistic representation model is extended for reasoning with uncertain and qualitative information in Dezert-Smarandache Theory （DSmT） framework, in order to overcome the limitations of current approaches, i.e., the lack of precision in the final results of linguistic information fusion according to 1-Tuple representation （ q1 ）- The linguistic information which expresses the expert＇s qualitative beliefs is expressed by means of mixed 2 Tuples （equidistant linguistic labels with a numeric biased value）. Together with the 2-Tuple representation model, some basic operators are presented to carry out the fusion operation among qualitative information sources. At last, through simple example how 2-Tuple qualitative DSmT-based （q2 DSmT） fusion rules can be used for qualitative reasoning and fusion under uncertainty, which advantage is also showed by comparing with other methods.展开更多

The sample (N = 70) involved two intact groups of college students. Subjects in one group exposed to instruction in the form of etymological familiarity while subjects in the comparison group were asked to memorize idioms on the basis of their given meaning. Subjects were then administered two post-tests: one to assess initial idiom acquisition, and another four weeks later to assess idiom retention. Statistical analyses produced sufficient support for both the first hypothesis (that the etymological elaboration condition would acquire more idioms than the rote memorization condition), and the second hypothesis—that the etymological familiarity would exhibit superior retention rates. The finding of this study suggests that for the purpose of encouraging long-term retention, elaborating on the original usage of idioms is preferable to requiring students to learn idioms by rote.展开更多
