The general idea underlying adaptive smoothing is to adapt the short-term sub-band mean of the amplitude to the local attributes of speech on the basis of discontinuity measures. The adaptive smoothing algorithm in this paper utilizes a scale-space framework through the minimal description length （MDL）. We recommend using the fuzzy muhi-attribute decision making approach to select the proper sub-bands where the word boundary can be more reliably detected. The process and simulation of the fuzzy adaptive smoothing algorithm are given. The parameters utilize the mean amplitude of the audible frequency range （300 -3 700 Hz） and the sub-band mean of the amplitude （16 band filter-bank）. We selected the audible band energy because of its usefulness in detecting high-energy regions and making the distinction between speech and noise. Otherwise, the fuzzy adaptive smoothing algorithm is processed in sub-band speech to utilize the full range of frequency information.展开更多

Most of researches are experiment-based and depend on the certain context. This paper addresses the question of ＂Is recast the most effective form of corrective feedback？＂ by two of Second Language Acquisition （SLA） approaches： cognitive approach and sociolinguistic approach. Empirical research will be used as complement. Theoretically speaking, SLA hypotheses in cognitive approach exist disagreements. Interaction hypothesis favors recast while both input hypothesis and output hypothesis doubt the effectiveness of it. Sociolinguistic approach underscores the significance of appropriate and timely corrective feedback and does not give more credit to certain strategy. Both approaches provide the pedagogical implications and elements to take into account for adopting recasts.展开更多

No contemporary mentality can avoid the intuition that we are facing a reality that seems to belong to the field of religion. Hence, what interests us is precisely the moral consideration of this discussion. Facing the morality of forgiveness, the questions that are raised with respect to each type are： whether it is possible to forgive and whether one should forgive. The inherent contradiction of those who affirm the obligatory nature of forgiveness results in the supererogatory character of forgiveness. If all forgiveness is supererogatory in itself, then all forgiveness is always presented as something undeserved. Thus, we do not have supporting points to embark on a discourse about forgiveness. The result is that our political communities do not really know how to manage situations such as transitional justice.展开更多
