关于正则运动方程完全对称化的问题

正则运动方程的两组(或个)式子原本只是基本对称,而不是完全对称.较好的完全对称方案,前人早已设计好了.本文将介绍两种方案,一种是采用矩阵,将正则运动方程的两组整合为一组,另一种是采用泊松(Poisson)括号,将其完全对称化.

Learning strategies and reading literacy among Chinese and Finnish adolescents: evidence of suppression

Many arguments have been advanced in the context of the predictive correlation between learning strategies and reading achievement. There is insufficient understanding, however, of the subtle ways in which different types of learning strategies (i.e. memorisation, elaboration and control strategies) function in facilitating students’ reading achievement. A post hoc analysis was performed to examine this issue among Chinese and Finnish adolescents who participated in the PISA 2009 reading programme. A multigroup structural equation modelling found the suppression pattern among the three strategies: control strategy is positively related to reading literacy and this association increases substantially once memorisation and elaboration strategies are accounted for. There is evidence that Chinese adolescents outperformed their Finnish counterparts due to larger suppression effect from elaboration. Implications for models of learning strategies and intervention are discussed.     

Examining the moderating effect of individual-level cultural values on users’ acceptance of E-learning in developing countries: a structural equation modeling of an extended technology acceptance model

In this study, we examine the effects of individual-level culture on the adoption and acceptance of e-learning tools by students in Lebanon using a theoretical framework based on the Technology Acceptance Model (TAM). To overcome possible limitations of using TAM in developing countries, we extend TAM to include subjective norms (SN) and quality of work life constructs as additional constructs and a number of cultural variables as moderators. The four cultural dimensions of masculinity/femininity (MF), individualism/collectivism, power distance and uncertainty avoidance were measured at the individual level to enable them to be integrated into the extended TAM as moderators and a research model was developed based on previous literature. To test the hypothesised model, data were collected from 569 undergraduate and postgraduate students using e-learning tools in Lebanon via questionnaire. The collected data were analysed using the structural equation modelling technique in conjunction with multi-group analysis. As hypothesised, the results of the study revealed perceived usefulness (PU), perceived ease of use (PEOU), SN and quality of work life to be significant determinants of students’ behavioural intention (BI) towards e-learning. The empirical results also demonstrated that the relationship between SN and BI was particularly sensitive to differences in individual-cultural values, with significant moderating effects observed for all four of the cultural dimensions studied. Some moderating effects of culture were also found for both PU and PEOU, however, contrary to expectations the effect of quality of work life was not found to be moderated by MF as some previous authors have predicted. The implications of these results to both theory and practice are explored in the paper.
