This paper proposes a new multiattribute group decision making method based on Pythagorean uncertain linguistic variable Hamy mean(PULVHM) operator and VIKOR method. Firstly, we define operation rules and a new aggregation operator of Pythagorean uncertain linguistic variable(PULV) and explore some properties of the operator.Secondly, taking the decision makers' hesitation degree into account, a new score function is defined, and we further develop a new group decision making approach integrated with VIKOR method. Finally, an investment example is demonstrated to elaborate the validity of the proposed method. Sensibility analysis and comprehensive comparisons with another two methods are performed to show the stability and advantage of our method.展开更多

However, the so-called between-class ability grouping which is prohibited by Taiwan government is still found in many places; and Taiwan's cram schools are even more popular and diversified than before. The authors argue that, in addition to individual's socio-economic background, regional characteristics and school attributes also play important roles. Bringing these two factors back in, the causal relationships among ability grouping, cram schooling, and student academic achievement can be analyzed more accurately. Using data from Taiwan Education Panel Survey, the authors' empirical results show that, first of all, in more urbanized area, between-class ability grouping is less popular but cram school participation is wider spread these years. Secondly, the effects of family backgrounds on students' cram school participation are not as critical as they were before. Thirdly, between-class ability grouping and students' performance are positively associated but the internal mechanism still needs further investigation.展开更多

In the application of soil data clustering, there is a lack of good understanding of the response of clustering performance to different features subsets. In the present paper, we analyzed the performance differences between k-means, fuzzy c-means, and spectral clustering algorithms in the conditions of different feature subsets of soil data sets. The experimental results demonstrated that the performances of spectral clustering algorithm were generally better than those of k-means and fuzzy c-means with different features subsets. The feature subsets containing environmental attributes helped to improve clustering performances better than those having spatial attributes and produced more accurate and meaningful clustering results. Our results demonstrated that combination of spectral clustering algorithm with the feature subsets containing environmental attributes rather than spatial attributes may be a better choice in applications of soil data clustering.展开更多

The purposes ot this study are to investigate the development of Chinese EFL learners' attributions for their perceived success and failure in second language reading and to clarify the relationship between learners' reading proficiency levels and their attributions. The results show that (1) Nearly half of the university students feel "Just so so" in English reading; (2) Environmental variables such as teacher feedback, peers or classroom play an influential role in the learners' attribution. This paper concludes with a number of pedagogical suggestions for the teaching and learning of English reading.展开更多
