The study looked at language teachers’ views of their students’ disengagement in e-learning during COVID-19. It described efforts on how to engage the learners beyond screen, where teachers have no control, and overcome issues disturbing engagement, motivation, achievement. learning engagement as an important requirement e-learning, which is influenced by social factors including communication ...

Web server log analysis is being increasingly used to evaluate the user behaviour on healthcare resource web sites due to the detailed record of activity that they contain. This study aimed to use this information to evaluate the e-Bug web site, a healthcare resource that provides a range of educational resources about microbes, hand and respiratory hygiene, and antibiotics. This evaluation was...

We modify an otherwise standard medium-sized DSGE model, in order to study the macroeconomic e§ects of placing leverage restrictions on financial intermediaries. The financial intermediaries (‘bankers’) in the model must exert e§ort in order to earn high returns for their creditors. An agency problem arises because banker e§ort is not observable to creditors. The consequence of this agency prob...

In this paper we propose a new registration algorithm. The proposed algorithm consists of two steps. The rst step is to estimate the transformation parameters among multiple range views, making use of the eigenvectors of the weighted covariance matrix of the 3-D coordinates of data points. The weighting factors are carefully selected to take into account the projection e ect caused by di erent ...

We consider the view data lineage problem in a warehousing environment For a given data item in a materialized warehouse view we want to identify the set of source data items that produced the view item We formalize the problem and we present a lineage tracing algorithm for relational views with aggregation Based on our tracing algorithm we propose a number of schemes for storing auxiliary view...
