Mining social media divides: an analysis of K-12 U.S. School uses of Twitter     

Royce Kimmons  Jeffrey P. Carpenter  George Veletsianos  Daniel G. Krutka 《Learning, Media and Technology》2018,43(3):307-325

This study utilizes public data mining to explore participation divides of all available K-12 institutional Twitter accounts in the U.S. (n?=?8275 accounts, n?=?9,216,853 tweets). Results indicated that U.S. schools used Twitter to broadcast information on a variety of topics in a unidirectional manner and that hashtags included a variety of intended purposes, including affinity spaces, education topics, emotive language, and events. Those schools in wealthier, more populated areas were more likely to use Twitter, with wealthy, suburban schools being the most likely to use it and poor, rural schools being the least likely. Furthermore, factors such as charter school status and urbanity influenced the content of school tweets on key issues, with schools in more populated areas tweeting more about coding and college than schools in less populated areas and charter schools tweeting more about college and the politicized educational issue of common core than non-charters. These results reveal participation differences between schools based upon demographics and provides a basis for conducting future large-scale work on publicly available artifacts, such as school tweets, that may be meaningfully used as education research data.  相似文献   

Potential theory method for 3D crack and contact problems of multi-field coupled media: A survey     

Chen?Wei-qiu?Email author  Ding?Hao-jiang 《浙江大学学报(A卷英文版)》2004,5(9):1009-1021

This paper presents an overview of the recent progress of potential theory method in the analysis of mixed boundary value problems mainly stemming from three-dimensional crack or contact problems of multi-field coupled media. This method was used to derive a series of exact three dimensional solutions which should be of great theoretical significance because most of them usually cannot be derived by other methods such as the transform method and the trial-and-error method. Further, many solutions are obtained in terms of elementary functions that enable us to treat more complicated problems easily. It is pointed out here that the method is usually only applicable to media characterizing transverse isotropy, from which, however, the results for the isotropic case can be readily obtained.

延时折扣范式下大学生课堂媒体多任务现象的行为经济分析     

张梅  丁书恒 《黑龙江高教研究》2020,(1):138-143

为探讨中国大学生课堂媒体多任务行为背后的冲动性机制,采用由经典延时折扣范式改编的课堂假想情景实验考察了101名大学生的课堂发消息行为。拟合分析结果表明大学生课堂发消息行为本质上是一种在即时少量报酬和延迟丰厚报酬间权衡时做出的冲动性的选择。进一步采用曲线下面积辅助分析发现女生比男生更少进行课堂发消息行为,而且女生在有趣课堂中比在枯燥课堂中更少进行课堂发消息行为。文章提供了对于中国大学生课堂媒体多任务行为的行为经济学分析思路。  相似文献   

平面体波在各向异性媒质中的传播   总被引：1，自引：0，他引：1  

张海燕  刘镇清 《上海大学学报(英文版)》2004,8(2):164-168

Combining the linear transformation and the solution technique for the cubic equation,a general closed-form analyti solution for bulk waves in orthotropic anisotropic materials is obtained.This method is straightforward and general.Degenerated cases include transversely isotropic,cubic,and isotropic materials.Numerical computations are carried out on a fiber-reinforced composite plate modeled as a transversely isotropic media.The fibers are parallel to the top and bottom surfaces of the plate ,and they are rotated counterclockwise around the plate normal through different angles.The two-dimensional slowness curves corresponding to different rotations are presented graphically.The wave propagation characteristics displayed in slowness surfaces for different fiber orientation are analyzed.  相似文献

Mutual perceptions of Chinese and German students at a German university: stereotypes,media influence,and evidence for a negative contact hypothesis     

Jan-Philipp Stein  Xiaomeng Lu  Peter Ohler 《Compare》2019,49(6):943-963

ABSTRACT

In recent years, China and Germany have become invaluable partners in business, politics, and science. However, psychological research indicates that the countries’ large-scale affinity does not translate onto the individual level, with many Germans expressing more reservations towards China than vice versa. Previous content analyses have connected this effect to imbalances in media tonality, as German media mostly criticise Chinese politics, contrasting with idealised portrayals from the other direction. Acknowledging the particularly high number of Chinese exchange students in Germany, we investigate mutual stereotypes (both explicit and implicit) in the context of a German university, while also exploring students’ perceptions of media tonality. Despite observing mostly positive explicit stereotypes, we find that both groups strongly prefer their country of origin on an implicit level, matching their generally sparse contact in university life. Based on our results, we discuss implications for students, educators, and decision-makers in the media.  相似文献
