Online social viewing: Cross-cultural adoption and uses of bullet-screen videos     

Anan Wan  Leigh Moscowitz  Linwan Wu 《Journal of International and Intercultural Communication》2020,13(3):197-215

ABSTRACT

Bullet-screen technology, an innovative way of interacting with online videos, allows viewers to contribute comments that simultaneously appear over videos. Popular in East Asia, the technology is making its way to American audiences. This study employed a comparative qualitative focus group approach to explore how American and Chinese viewers responded to and interacted with this new format of online videos. Three themes emerge from this investigation: (1) the unique affordances of this technology; (2) barriers to adoption and usage; and (3) cultural differences that impact the user experience. The theoretical and practical implications for bullet-screen technologies are discussed.  相似文献

There is a paucity of data regarding trends in the incidence of heart disease in China during recent years. Using a large echocardiography database in our center, we analyzed trends in the prevalence of several common heart diseases from Dec. 2003. This study retrospectively analyzed the echocardiographic database in our Department from 2003 to 2012. A total of 385 682 cases were included in the study. The prevalence of rheumatic heart disease decreased over the 10-year period, from 4.04% in 2003 to 3.06% in 2012 (P<0.01). Infective endocarditis also decreased, from a mean prevalence of 0.37% in July 2003 to 0.27% in Dec. 2008 (P<0.001). The prevalence of hypertrophic cardiomyopathy, which includes 20% apical hypertrophic cardiomyopathy and 20% hypertrophic obstructive cardiomyopathy, was about 1.8%. The prevalence of the three most common adult congenital heart diseases (CHDs) decreased by about 10% from July 2003 to Dec. 2008 (all P<0.001). The prevalence of moderate pulmonary arterial hypertension (PAH) or left ventricular systolic dysfunction (LVSD) decreased during the 10-year period (P<0.001), but there was no change in the prevalence of severe PAH or LVSD (P>0.05). The present study indirectly demonstrates that the prevalence of several common heart diseases in China has declined in recent years.  相似文献

“以正面宣传为主”是我国新闻报道的基本方针。作为新闻舆论的重要组成部分，舆论监督应以党性原则、真实性原则等根本原则为基石．在舆论监督过程中，新闻工作者应该贯彻辩证的思维方法，以应付复杂多变的舆论监督环境．  相似文献   

乡村中青年教师流动的场域、惯习、资本作用机制研究     

万怡 《教育与经济》2021,37(3):88-96

基于场域、惯习和资本视角,采用个案研究方法对乡村易流动的中青年教师与非流动的老年教师群体进行比较.研究发现:乡村中青年教师流动受到多种因素影响,从场域角度分析,他们所受城乡二元结构影响不同;从惯习角度分析,与传统美德和等级观念淡化相关;从资本角度分析,中青年教师流动以实现资本积累与再生产为诉求.实现城乡场域深度融合、培养教师乡土情怀、引入分层激励机制、实现双向轮岗交流,是解决乡村教师流失的有效手段.  相似文献

道德自我认同、自尊和网络匿名性对网络利他行为的影响:一个有调节的中介模型     

刘慧瀛  杨静怡  王婉  冯慧 《中国特殊教育》2021,(1)

为探讨道德自我认同对网络利他行为的影响机制,采用网络利他行为问卷、道德自我认同问卷、自尊量表以及感知匿名性问卷对704名大学生进行问卷调查。结果发现:(1)道德自我认同能够显著预测网络利他行为;(2)自尊在道德自我认同对网络利他行为的影响中起部分中介作用;(3)网络匿名性能够调节道德自我认同经由自尊影响网络利他行为的直接路径。本研究结果揭示了道德自我认同对网络利他行为的影响及其作用机制,为有效促进大学生的网络利他行为提供有益的理论指导。  相似文献   

省域内高等职业教育生均经费基尼系数研究——基于广东省公办高职院校的统计数据     

万伟平  聂劲松  樊孝凯 《当代教育论坛》2021,(5):116-124

为揭示高等职业教育经费投入的区域不均衡性,研究采用基尼系数为研究工具,对近5年广东省高等职业教育生均教育经费相关数据进行了实证分析,结果表明:区域经济发展的不均衡与高等职业教育发展的不均衡存在明显关联性;近年来广东省高等职业教育经费投入差距没有出现明显改善,其经费投入不均衡干预机制还未完全建立或未实现有效运行.为促进高等职业教育区域均衡发展,应设立高职教育生均经费标准,构建欠发达地区高等职业教育投入长效机制;以创新市级财政上缴机制为抓手,集中财力支持欠发达地区;以企业投入为主,拓宽社会化投入渠道;构建高等职业教育区域均衡发展监控机制;提高高等职业教育经费使用效益.  相似文献   

Opposite effects of miR-155 in the initial and later stages of lipopolysaccharide (LPS)-induced inflammatory response     

Liu  Yuhua  Wan  Xiaopeng  Yuan  Yuan  Huang  Jingjing  Jiang  Yijia  Zhao  Kaiyue  Wang  Yan  Liu  Yang  Wang  Qingqing  Jin  Hongchuan 《Journal of Zhejiang University. Science. B》2021,22(7):590-598

Although microRNA-155(miR-155) is considered a pro-inflammatory mediator, cumulative evidence indicates that it also has anti-inflammatory effects in macrophages and dendritic cells. In this study, we identified the dramatic expression changes of more than half of potential miR-155-targeted genes upon lipopolysaccharide(LPS) stimulation; 223 genes were down-regulated and 85 genes were up-regulated, including suppressor of cytokine signaling 1(SOCS1) and transforming growth factor-β-activated kinase 1-binding protein 2(TAB2), two well-known genes involved in miR-155-mediated regulation of the Toll-like receptor 4(TLR4) signaling pathway. We also found that miR-155 acted as an anti-inflammatory mediator in the initial stage of LPS-induced inflammatory response mainly through repressing TAB2 protein translation, and as a proinflammatory mediator by down-regulating SOCS1 in the later stage. Meanwhile, overexpression of TAB2 3' untranslated region(UTR) in macrophages promoted the development of endotoxin tolerance by competing for binding with miR-155, which resulted in an elevated expression level of SOCS1 protein. These findings provide new insights for understanding the regulatory mechanisms in fine-tuning of LPS-induced innate immune response.  相似文献
