Component skills of text comprehension in less competent Chinese comprehenders

The present study examined the role of verbal working memory (memory span and tongue-twister), two-character Chinese pseudoword reading (two tasks), rapid automatized naming (RAN) (letters and numbers), and phonological segmentation (deletion of rimes and onsets) in inferential text comprehension in Chinese in 31 less competent comprehenders compared with 37 reading comprehension control students and 23 chronological age controls. It was hypothesized that the target students would perform poorly on these cognitive and linguistic tasks as compared with their controls. Furthermore, verbal working memory and pseudoword reading would explain a considerable amount of individual variation in Chinese text comprehension. RAN would have a nonsignificant role in text comprehension. Structural equation analyses and hierarchical multiple regression analyses generally upheld these hypotheses. Our findings support current literature of the role of verbal working memory in reading comprehension found in English. The results, however, suggest differential role of the constructs and the tasks in reading comprehension and provide some answers for comprehension impairment in Chinese students.

基于无人机激光点云的树障检测与砍伐树木数量估算

电力走廊的树木生长会对输电线路的安全运营造成巨大影响,精确检测出影响线路安全的树木并将其砍伐至关重要。因此,提出一种基于无人机激光点云的树障检测与砍伐树木数量估算方法。首先,对激光点云进行快速自动化处理,先后精确提取地面点、电力线点与植被点;其次,基于电力线点进行分段,并分析电力线与植被点的安全距离,进而确定树障区域的位置和范围;最后,对树障区域植被点云进行单木分割,并统计单木数量,最终实现砍伐树木数量的精准估算。研究结果表明,无人机激光点云可以实现输电通道树障的有效检测与砍伐树木数量的精确估算,总体树木砍伐数量估算精度可达92.3%,可为输电线路安全运营提供遥感技术支撑,也可为电网运维单位制订树木砍伐计划提供可靠依据。     

基于碎片分词的未登录词识别方法

提出了一种新的基于碎片分词的未登录词识别方法。该方法首先对文本进行分词,然后对分词结果中的碎片进行全切分生成临时词典,并利用规则和频度信息给临时词典中的每个字串赋权值,最后利用贪心算法获得每个碎片的最长路径,从而提取碎片中的未登录词。实验证明该方法开放测试的准确率达到82.88%,召回率达到87.51%。

Social media and the university decision. Do prospective students really care?

In the world of social media marketing, colleges and universities can benefit from enhanced understanding of how prospective students use social media. Due to the ever-evolving nature of social media use, there are gaps in the current research regarding how students use social media to aid in their matriculation decision-making. Using survey data from current university students across the U.S. (n?=?364) and one-on-one interviews (n?=?12) with students at a small liberal arts college, the authors address conflicting information where students report both using and not using social media to narrow their search and make their matriculation decision. The findings suggest that while students may not report visiting social media sites or may report that social media does not impact their matriculation decision when asked in a survey, in interview settings the vast majority of students reported using social media platforms to learn more about higher education schools under consideration. By exploring which platforms students use and the selection of platforms for specific use cases, the authors provide suggestions and guidelines for social media managers looking to maximize the effectiveness of their social media recruiting strategies and campaigns.
