It is the unity of what is said and what is implicated. Grice's theory of conversational implicature provides some explicit account of how it is possible to mean more than what is literally expressed by the conventional sense of the linguistic expressions uttered. Using this theory, we can infer the speaker's real attention, appreciate figure of speech in literary work, and improve our communicative competence.展开更多

This discussion highlights three components---organizational competence, pragmatic competence and strategic competence in Bachman's. Only when we have knowledge of language and the capacity to execute the competence, could we apply the communicative pedagogical applications properly into the Communicate Language Teaching (CLT) to achieve these competences.展开更多

If humidity is too high or the change is too fast it will lead to an abnormal change on data. The intelligent real-time humidity analysis and monitoring system of a geomagnetic room and probe can not only monitor and display the change of humidity in the geomagnetic room and send an alarm signal when it exceeds the pre-set range, but also dehumidify intelligently. One can arbitrarily control the sensor to monitor the ambient humidity of the probe in order to ensure that the data is stable and true. The design idea and main functions of the system are introduced in the paper.展开更多

The research results show that Chinese students had both linguistic and socio-cultural problems in communication. Two case studies are presented of good and less good communicators to show up different patterns of communicative performance and learning strategies. In conclusion, a range of findings support the statement that attitudes, motivation and immersion were important in the development of communicative competence.展开更多

Go beyond the level that can be achieved, using only conventional natural language processing and vast repositories of sample patterns. In this paper, the authors propose a method for computer conversation sentences generated using newspaper headlines as an example of how the common knowledge and associative ability are applied.展开更多

In Russia, it is called"Gerasimovism". Russia adapted the idea of hybrid warfare for its military operations in Ukraine and Syria into a Russian-style hybrid warfare that has seen successful results so far. This model is likely to impact future military developments.展开更多

The aim of the research was to achieve optimal performance by the athletes during the kumite1 in karate. The research involved initial, control and final experiment, where the karate practitioners were focused on the training model given (group; n = 13) and working in a group with additional individual intensive sessions provided for each participant. All athletes were male contestants aged 26.4 - 6.8. The aim of the research was to explore how their performance can be influenced using psychological techniques during karate trainings, or how not to fall into one of the four undesirable states of mind called Shikai2. Results confirmed that the model of combined physical and mental training for athletes improves their physical skills and optimizes performance during competitions.展开更多

文摘By exact resolution of coupled ideal chains connecting an extra side site,we show that the so-called'anti-resonant effect' is suppressed when the electron energy is inside the overlap region of extended bands of the idealtight-binding chains.When the electronic energy is outside the band overlap region,the existence of 'anti-resonanteffect' is tuned by details of local connectivity around the extra side site and can be suppressed by introduction ofmagnetic flux.
