News audience fragmentation in the Japanese Twittersphere     

Tetsuro Kobayashi  Takahisa Suzuki  Hitoshi Yamamoto 《亚洲交流杂志》2019,29(3):274-290

ABSTRACT

Although computational approaches to ideology-based audience fragmentation are promising, they are not without limitations. First, most existing studies have focused on the US, and the cross-national validity of their results has rarely been tested. Second, previous studies that rely solely on behavioral data from social media tend to make strong analytical assumptions such as that Twitter users prefer to follow media and politicians whose ideological positions are similar to their own, and that the ideologies of political elites can be extrapolated to infer the ideologies of ordinary users. We aim to address these limitations. First, we focus on Japan to test the generalizability of US findings in an Asian context. Second, we do not rely solely on behavioral measurement but combine survey and social media data to infer the ideologies of Twitter users. Results indicate that our classifier built based on these self-reported ideologies produces more valid estimates than naïve extrapolation from views of the elites. Based on these improved estimates of Twitter users’ ideologies, we demonstrate that the ideological distributions of those who follow major Japanese media accounts on Twitter largely overlap, suggesting an absence of ideology-based audience fragmentation.  相似文献   

露迹:新生代小说中的元小说叙事手法   总被引：1，自引：0，他引：1  

赵映环 《阜阳师范学院学报(社会科学版)》2015,(2)

"露迹"是最重要的元小说叙事手法之一,也是先锋小说家们常用的写作策略。"露迹"手法的使用是新生代小说对先锋小说多元化创作的一种继承。但新生代小说家们将"露迹"手法纳入了更为合理的范畴,摆脱了先锋元小说创作中"形式大于内容"的怪圈。  相似文献   

A preliminary mapping of individual,relational, and social factors that impede disclosure of childhood sexual abuse     

《Child abuse & neglect》2015

Uncovering the pathways to disclosures of child sexual abuse (CSA) and the factors influencing the willingness of victims to talk about the abuse is paramount to the development of powerful practice and policy initiatives. Framed as a long interview method utilizing a grounded theory approach to analyze data, the objective of the current study was to provide a preliminary mapping of the barriers to CSA disclosures through an ecological systemic lens, from a sample of 67 male and female CSA adult survivors, all of whom had recently received counselling services. The current project led to the identification of three broad categories of barriers that were each comprised of several subthemes, namely: Barriers from Within (internalized victim-blaming, mechanisms to protect oneself, and immature development at time of abuse); Barriers in Relation to Others (violence and dysfunction in the family, power dynamics, awareness of the impact of telling, and fragile social network); and Barriers in Relation to the Social World (labelling, taboo of sexuality, lack of services available, and culture or time period). This study points to the importance of using a broad ecological framework to understand the factors that inhibit disclosure of CSA, as barriers to disclosure do not constrain solely the victims. Results are discussed in light of their implications for research, prevention and intervention programs, and social policies and media campaigns, as the burden is on the larger community to create a climate of safety and transparency that makes the telling of CSA possible.  相似文献   

新媒体语境特征与用户态度关系构建的实证研究     

薛可  阳长征  余明阳 《湖南师范大学社会科学学报》2015,(3):153-160

通过对上海市民进行抽样调查,并使用结构方法模型对新媒体语境下的受众社会态度倾向进行实证研究,得出如下结论：新媒体语境通过社会懈怠对用户风险偏好和群体极化倾向产生正向影响,对责任与公平意识、道德发展以及亲社会倾向产生负向影响;媒体接触频率在新媒体与社会懈怠关系中具有显著正向调节作用,而媒体接触的多样性在其中的调节作用并不明显;在主效应和调节作用中,均表现出对男性的影响大于对女性的影响,其影响大小随着年龄的增加而呈减弱趋势。  相似文献   

Epidemiology of injuries in First Division Spanish football

Abstract

The aim was to examine the injuries sustained by Spanish football players in the First Division and to compare injury-related variables in the context of both competition and training. The injury data were prospectively collected from 16 teams (427 players) using a specific web-based survey during the 2008/2009 season. A total of 1293 injuries were identified (145 were recurring injuries). The overall injury incidence was 5.65 injuries per 1000 h of exposure. Injuries were much more common during competition than during training (43.53 vs. 3.55 injuries per 1000 h of exposure, P < 0.05). Most of the injuries (89.6%) involved the lower extremities, and overuse (65.7%) was the main cause. Muscle and tendon injuries were the most common types of injury (53.8%) among the players. The incidence of training injuries was greater during the pre-season and tended to decrease throughout the season, while the incidence of competition injuries increased throughout the season (all P < 0.05). In conclusion, the results of this study suggest the need for injury prevention protocols in the First Division of the Spanish Football League to reduce the number of overuse injuries in the muscles and tendons in the lower extremities. In addition, special attention should be paid during the pre-season and the competitive phase II (the last four months of the season) in order to prevent training and competition injuries, respectively.  相似文献

The challenges of undergraduate online learning experienced by older workers in career transition     

Christopher A. Meyers  Richard G. Bagnall 《International Journal of Lifelong Education》2017,36(4):442-457

This paper presents the findings of a research project on older workers transitioning into work as vocational educators through online undergraduate university study. The study involved interpretive phenomenological analysis of the experiences of 10 older learners. Their experience of online learning was found to be shaped by diverse influences and to comprise three distinct but interrelated elements: their use of technology, their use of hypermedia and their independent learning. Challenges raised by each of these elements called for a distinctive response from the university, respectively: short-term, readily available technical advice and support; tutoring to develop Web navigation and exploration skills, or the provision of selected readings; and opportunities for online or face-to-face dialogical engagement with others. Recommendations for the online provision of higher education for such learners, then, pointed to the need for an appropriately distinctive response to challenges in each of the three elements: the use of technology calling for individualised and immediate responsiveness to learner issues; the use of hypermedia calling for aggregated advice and resources prepared in advance; and independent learning calling for the prior structuring of opportunities for interactive engagement. Further research is suggested focusing on the relative cost and effectiveness of different approaches to addressing those needs.  相似文献   

Narrative construction of professional teacher identity of teachers with dyslexia   总被引：1，自引：0，他引：1  

Eila Burns  Sheena Bell   《Teaching and Teacher Education》2011,27(5):952-960

This paper considers the development of teachers’ professional identity in the context of educators that have diverse backgrounds. We elucidate how teachers with dyslexia working in tertiary education use narrative resources to construct and negotiate their professional teacher identities. The analysis of narrative interviews, interpreted within the framework of positioning theory and the theories of narrative identity, indicated that the interviewees constructed several professional teacher identities that were closely linked to each teacher’s perception of their dyslexia. The experience of dyslexia was clearly evident as a positive element in each identity. Instead of seeing it as an obstacle it can become a part of the teacher’s own identity and can be used as a tool to thrive in their profession.  相似文献
