Bounded space algorithms for variant of variable-sized bin packing

Given a list of items and a sequence of variable-sized bins arriving one by one, it is NP-hard to pack the items into the bin list with a goal to minimize the total size of bins from the earliest one to the last used. In this paper a set of approximation algorithms is presented for cases in which the ability to preview at most k（〉=2） arriving bins is given. With the essential assumption that all bin sizes are not less than the largest item size, analytical results show the asymptotic worst case ratios of all k-bounded space and offiine algorithms are 2. Based on experiments by applying algorithms to instances in which item sizes and bin sizes are drawn independently from the continuous uniform distribution respectively in the interval [0,u] and [u,l ], averagecase experimental results show that, with fixed k, algorithms with the Best Fit packing（closing） rule are statistically better than those with the First Fit packing（closing） rule.     

＂E-book flood＂ for changing EFL learners＇ reading attitudes

This paper was intended to investigate the effects of using e-books （or texts with multimedia support） in an ERP （extensive reading program） on EFL （English as a foreign language） learners＇ attitudes toward reading in English. In a junior high school in northern Taiwan, 109 students from 3 intact classes were recruited in the 10-week ERP of e-books. Each class was introduced to a list of 140 selected e-books for the reading program; each student was then encouraged to read e-books after school, with the target of reading 4 e-books every week. The degree of changes in reading attitudes was assessed by using the reading attitudes scale （Stokmans, 1999） before and after the e-book ERP. In addition, the teacher＇s class notes of the students＇ reading behaviors and reactions as well as their spontaneous oral or written feedback were analyzed to be triangulated with the quantitative data. The results showed that the e-books had positive effects on the students＇ attitudinal changes in all dimensions of reading attitudes, namely, utility, development, enjoyment and escape, as well as in all the cognitive, affective and conative components. The results also showed that the features of the e-books, especially oral reading, highlighting, animations and music/sound effects, were considered important to change their attitudes. The implementation of interaction and learner control in the e-books guaranteed positive attitudinal changes as well.
