大学生移动学习需求的实证分析   总被引：1，自引：0，他引：1  

茆意宏  魏雅雯 《图书情报工作》2013,57(8):82

在阐述移动学习需求理论框架的基础上,从移动学习内容与服务需求两个方面,对我国大学生移动学习需求的特征进行抽样调查与分析发现:大部分大学生需要移动学习服务;其移动学习的内容需求包括课堂内外与学习相关的即时性内容,长短适中,以文本形式为主,其次是图片、视频、音频;移动学习终端以智能手机与平板电脑为主;移动学习软件以客户端、WAP、短信息为主;大多数学生既需要自行订阅或查询学习内容,也需要个性化的移动学习推送服务;需要配套的学习网络社区;希望移动学习服务是免费服务。在此基础上,提出基于大学生移动学习需求特征的服务对策。  相似文献   

Determination of the genetic diversity of vegetable soybean [Glycine max (L.) Merr.] using EST-SSR markers     

Gu-wen Zhang  Sheng-chun Xu  Wei-hua Mao  Qi-zan Hu  Ya-ming Gong 《Journal of Zhejiang University. Science. B》2013,14(4):279-288

The development of expressed sequence tag-derived simple sequence repeats (EST-SSRs) provided a useful tool for investigating plant genetic diversity. In the present study, 22 polymorphic EST-SSRs from grain soybean were identified and used to assess the genetic diversity in 48 vegetable soybean accessions. Among the 22 EST-SSR loci, tri-nucleotides were the most abundant repeats, accounting for 50.00% of the total motifs. GAA was the most common motif among tri-nucleotide repeats, with a frequency of 18.18%. Polymorphic analysis identified a total of 71 alleles, with an average of 3.23 per locus. The polymorphism information content (PIC) values ranged from 0.144 to 0.630, with a mean of 0.386. Observed heterozygosity (H _o) values varied from 0.0196 to 1.0000, with an average of 0.6092, while the expected heterozygosity (H _e) values ranged from 0.1502 to 0.6840, with a mean value of 0.4616. Principal coordinate analysis and phylogenetic tree analysis indicated that the accessions could be assigned to different groups based to a large extent on their geographic distribution, and most accessions from China were clustered into the same groups. These results suggest that Chinese vegetable soybean accessions have a narrow genetic base. The results of this study indicate that EST-SSRs from grain soybean have high transferability to vegetable soybean, and that these new markers would be helpful in taxonomy, molecular breeding, and comparative mapping studies of vegetable soybean in the future.  相似文献

Measurement Models,Estimation, and the Study of Change     

Kevin J. Grimm  Anthony P. Kuhl  Zhiyong Zhang 《Structural equation modeling》2013,20(3):504-517

The study of change is based on the idea that the score or index at each measurement occasion has the same meaning and metric across time. In tests or scales with multiple items, such as those common in the social sciences, there are multiple ways to create such scores. Some options include using raw or sum scores (i.e., sum of item responses or linear transformation thereof), using Rasch-scaled scores provided by the test developers, fitting item response models to the observed item responses and estimating ability or aptitude, and jointly estimating the item response and growth models. We illustrate that this choice can have an impact on the substantive conclusions drawn from the change analysis using longitudinal data from the Applied Problems subtest of the Woodcock–Johnson Psycho-Educational Battery–Revised collected as part of the National Institute of Child Health and Human Development's Study of Early Child Care. Assumptions of the different measurement models, their benefits and limitations, and recommendations are discussed.  相似文献   

Evaluation of Test Statistics for Robust Structural Equation Modeling With Nonnormal Missing Data     

Xin Tong  Zhiyong Zhang  Ke-Hai Yuan 《Structural equation modeling》2013,20(4):553-565

A 2-stage robust procedure as well as an R package, rsem, were recently developed for structural equation modeling with nonnormal missing data by Yuan and Zhang (2012). Several test statistics that have been used for complete data analysis are employed to evaluate model fit in the 2-stage robust method. However, properties of these statistics under robust procedures for incomplete nonnormal data analysis have never been studied. This study aims to systematically evaluate and compare 5 test statistics, including a test statistic derived from normal-distribution-based maximum likelihood, a rescaled chi-square statistic, an adjusted chi-square statistic, a corrected residual-based asymptotical distribution-free chi-square statistic, and a residual-based F statistic. These statistics are evaluated under a linear growth curve model by varying 8 factors: population distribution, missing data mechanism, missing data rate, sample size, number of measurement occasions, covariance between the latent intercept and slope, variance of measurement errors, and downweighting rate of the 2-stage robust method. The performance of the test statistics varies and the one derived from the 2-stage normal-distribution-based maximum likelihood performs much worse than the other four. Application of the 2-stage robust method and of the test statistics is illustrated through growth curve analysis of mathematical ability development, using data on the Peabody Individual Achievement Test mathematics assessment from the National Longitudinal Survey of Youth 1997 Cohort.  相似文献   

技术选择、投入强度与企业创新绩效研究   总被引：1，自引：0，他引：1       下载免费PDF全文

康志勇 《科研管理》2013,34(6):42-49

企业创新中的技术选择是不是越先进越好？企业创新中的投入强度是不是越强越好？本文在适宜技术理论框架下,通过大样本的中国本土制造业企业数据,对这一问题进行了探索性研究。通过实证检验发现:(1)在控制企业创新投入强度的情况下,企业创新的技术水平与创新绩效之间呈现出倒"U"型关系;(2)在控制企业创新技术水平的情况下,企业创新投入强度与创新绩效之间也呈现出倒"U"型关系。因此,过度强调创新技术的先进性以及创新投入的高强度不利于企业创新绩效的提高。企业创新活动必须遵循比较优势战略,通过促进企业自生能力的提升,实现创新绩效的最大化。  相似文献
