Abstract：目的:为《西南交通大学学报》学术影响力的提高提供理论依据。方法:利用中国知网引文数据库,以西南交通大学学报2014—2018年发表的818篇文献为统计数据源,分别对文献下载频次与被引频次进行数据相关性分析,计算出两者的线性相关系数,并进行了分析和探讨,讨论利用下载频次预测被引频次的可行性。结果:被引频次TOP50论文主要集中在2014—2015年(论文发表后的4～5年),其中,以2014年居首(27篇,占比54%);2015年发表的论文数其次(15篇,占比30%);2017年和2018年(论文发表后的1～2年)发表的论文都没有进入TOP50。下载频次TOP50的论文集中在2014—2016年(论文发表后的3～5年),分别占比32%。结论:下载频次在500～1000次时和被引频次拟合度好,高于1000次时分布比较分散;被引频次20次左右时和下载频次拟合度好,大于20次时分布比较分散,拟合度差。在特定范围内利用下载频次预测被引频次是可行的。

Abstract： [Purpose/significance] In the era of big data, the management of scientific data has received more and more attention from all walks of life. Therefore, the cultivation of data literacy talents in colleges and universities is becoming more and more important. The data literacy curriculum is an important basis for the data literacy training of college students.[Method/process] Using the questionnaire survey and Pearson correlation analysis method in SPSS.22 software, the article analyzed the relationship between information literacy curriculum which is closely related to data literacy and data literacy, and then refined the data literacy curriculum collection. Finally, clustering analysis was used to classify the data literacy curriculum.[Result/conclusion] The research results show that courses related to information literacy can be used as the basis for data literacy. On this basis, by supplementing and perfecting the corresponding data literacy courses, the article constructs the data literacy course group, including data awareness and ethics course module, data acquisition and data processing course module and data analysis and utilization course module.

Abstract： Background The research on sleep disorders in preschool children is less and have some limitations in China, and there is a lack of more validated scales for screening and assessment.Objective The objective of the current study was therefore to adapt and validate the the sleep disturbance scale for children (SDSC) for Chinese preschoolers,to provide an effective psychological assessment instrument for clinicians.Method: From April to November 2021, parents of preschoolers from Fuzhou, Quanzhou, Longyan, Sanming and Nanping in Fujian Province filled out the SDSC. The reliability and validity of the scales were assessed by item analysis, standard Cronbach's ɑ coefficient, exploratory factor analysis (EFA), confirmatory factorial analyses (CFA) and other measurement characteristics.Results: 370 out of 402 samples were valid.Cronbach's α coefficient of the full scale was 0.86, for the 6 dimensions were within 0.58-0.84.Bartlett's test of sphericity of χ2 value of the scale was 3013.297,and the KMO value was 0.845.Principal component analysis revealed that the factor loading of items ranged from 0.328-0.849, with 7 factors of eigenvalue >1, which could explain 65.125% of the total variance.However,a six-factor solution (i.e. six types of sleep disorder) based on parent-reported sleep disorder symptoms in our study indicated the factor loading of items ranged from 0.340-0.846, which could explain 60.539% of the total variance.The results of the confirmatory factor analysis showed: χ2/DF was 2.66, CFI was 0.835, TLI was 0.806,SRMR was 0.075,and RMSEA was 0.079.Conclusion: This study revealed that the Chinese version of SDSC in preschoolers is a valid and reliable scale that can provide a comprehensive and detailed assessment of sleep disorders in preschool children, which is beneficial to clinicians for early screening and assessment of sleep-related problems and deserves further promotion.
