重力异常处理中小子域滤波法的改进

在重力资料处理中,小子域滤波法会导致异常边界严重失真。为了弥补这一缺陷,提出一种改进的小子域滤波法,通过对子域剖分方式的改进以达到提升计算速度和控制异常边界失真的效果。通过模型试验对该方法的可行性进行验证,试验结果表明:重力异常数据利用改进的小子域滤波法多次迭代计算后,可以较好地反映地质体边界的分布情况,失真现象得到明显抑制;利用该方法描绘出虎林盆地断裂分布图,得到了25条断裂的分布情况,与已有的地质资料存在很好的对应关系。

Longitudinal test of ePortfolio continuous use: an empirical study on the change of students’ beliefs

The electronic portfolio (ePortfolio) is learner-centred, and its effectiveness depends on the learners’ long-term use. Thus, it is proper to conduct the study from the learners’ perspectives. Currently, most research on the use of the ePortfolio is in the form of cross-sectional studies, and it is difficult to find the reasons for the changes in students’ beliefs with regard to the long-term use of the ePortfolio. Based on the longitudinal test, this study explained the students’ continuous use of ePortfolio and the changes in their beliefs. With 122 samplers in the adoption–continuous stage (t ₁–t ₂) and 117 samplers in the continuous stage (t ₂–t ₃), this study demonstrates that in continuous use stage (t ₂–t ₃), perceived ease of use still influences the users’ perceived usefulness (PU) and attitude towards the ePortfolio. Attribution significantly moderates the users’ beliefs from the adoption stage (t ₁) to the continuous use stage (t ₂). However, the moderating effect of attribution in the continuous use stage (t ₂–t ₃) is insignificant; satisfaction and attribution are the key factors driving the users’ continuous intention towards the ePortfolio rather than PU and attitude. Meanwhile, satisfaction and attribution will change because of the users’ expectation disconfirmation, and it will influence the users to continue using ePortfolio.     

User satisfaction evaluation of microblogging services in China: using the tetra-class model

This study is aimed at revealing the contributions of microblogging services to user satisfaction in China. An empirical investigation was conducted to analyse user experience on the 36 main microblogging service elements, using a sample of 216 users of Sina Weibo, which is the biggest microblog in China. The tetra-class model was then applied to identify the contribution of each service element to the overall satisfaction. Through correspondence analysis, we calculated, respectively, the contribution to dissatisfaction when the service element was negatively evaluated and that to satisfaction when it was positively evaluated. Based on these two contribution values, we classified the service elements into four categories: Basic, Secondary, Plus, and Key. In order to know the preferences of different users towards the microblogging service elements, we segmented the users into groups according to their microblogging characteristics and personal attributes and then discussed the variations of the service, categorising among different user groups. Finally, we analysed the results and reached some conclusions, which could be helpful for the improvement of customised microblogging services.
