How and why are educators using Instagram?     

《Teaching and Teacher Education》2020

Social media are commonplace in many educators’ lives, but their Instagram activities have received no prior attention in the empirical literature. We therefore created and disseminated a survey regarding educators’ Instagram use. Analyses of 841 responses suggested participants were generally intensive users of Instagram who engaged in the exchange of both professional knowledge and wisdom, as well as affective support. In addition to identifying benefits to Instagram use, some participants offered critiques of Instagram’s professional utility. We discuss the implications of these findings for educators’ work in a digital era and the future of research on educators’ social media activities.  相似文献   

The effect of toxicity on COVID-19 news network formation in political subcommunities on Reddit: An affiliation network approach     

《International Journal of Information Management》2021

Political polarization remains perhaps the “greatest barrier” to effective COVID-19 pandemic mitigation measures in the United States. Social media has been implicated in fueling this polarization. In this paper, we uncover the network of COVID-19 related news sources shared to 30 politically biased and 2 neutral subcommunities on Reddit. We find, using exponential random graph modeling, that news sources associated with highly toxic – “rude, disrespectful” – content are more likely to be shared across political subreddits. We also find homophily according to toxicity levels in the network of online news sources. Our findings suggest that news sources associated with high toxicity are rewarded with prominent positions in the resultant network. The toxicity in COVID-19 discussions may fuel political polarization by denigrating ideological opponents and politicizing responses to the COVID-19 pandemic, all to the detriment of mitigation measures. Public health practitioners should monitor toxicity in public online discussions to familiarize themselves with emerging political arguments that threaten adherence to public health crises management. We also recommend, based on our findings, that social media platforms algorithmically promote neutral and scientific news sources to reduce toxic discussion in subcommunities and encourage compliance with public health recommendations in the fight against COVID-19.  相似文献

Identifying the combinations of motivations and emotions for creating satisfied users in SNSs: An fsQCA approach     

《International Journal of Information Management》2020

Social Networking Sites (SNSs) play an important role in our daily lives and the number of their users increases regularly. To understand how users can be satisfied in the complex digital environment of SNSs, this study examines how motivations and emotions combine with each other to explain high satisfaction. Users’ motivations comprise four attributes, entertainment, information, social-psychological, and convenience. Emotions are divided into their two main categories, that is positive and negative emotions. We draw on complexity and configuration theories, present a conceptual model along with propositions and perform a fuzzy-set qualitative comparative analysis (fsQCA). Through an empirically study with 582 SNSs users, we present eight combinations (configurations) of motivations and emotions that lead to high satisfaction, which highlight the role of high convenience, followed by entertainment and information motivations in being satisfied with SNSs. High satisfaction can be achieved both when positive and negative emotions are high and low, depending on how they combine users’ motivations. None of the factors are indispensable to explain high satisfaction on their own, instead they are insufficient but necessary parts of the causal combinations that explain high satisfaction. This study contributes in SNSs literature by extending current knowledge on how motivations and emotions combine to increase satisfaction, and by identifying specific patterns of users for whom these factors are important and influence greatly their satisfaction.  相似文献   

When information wanted to be free: Discursive bifurcation of information and the origins of Web 2.0     

Eran Fisher 《The Information Society》2018,34(1):40-48

In the 1990s the aphorism “information wants to be free” reigned supreme, limiting our thinking in consequential ways. In actuality this aphorism was a fragment of a much more nuanced statement by Steward Brand, who also talked about “information wants to be expensive.” It seemed for quite a while that there was no resolution to the contradiction: information as both free and expensive. Eventually Web 2.0 resolved this contradiction by providing an architecture where information could be both free and expensive. Web 2.0 was not a product of technological advances: social media, wikis, big data platforms, and so forth. It was borne out of the understanding that free information on media platforms could yield profitable data on users. This article lays bare the discursive moves through which this understanding came about.  相似文献   

Creating value from Social Big Data: Implications for Smart Tourism Destinations     

Pasquale Del Vecchio  Gioconda Mele  Valentina Ndou  Giustina Secundo 《Information processing & management》2018,54(5):847-860

This paper aims to demonstrate how the huge amount of Social Big Data available from tourists can nurture the value creation process for a Smart Tourism Destination. Applying a multiple-case study analysis, the paper explores a set of regional tourist experiences related to a Southern European region and destination, to derive patterns and opportunities of value creation generated by Big Data in tourism. Findings present and discuss evidence in terms of improving decision-making, creating marketing strategies with more personalized offerings, transparency and trust in dialogue with customers and stakeholders, and emergence of new business models. Finally, implications are presented for researchers and practitioners interested in the managerial exploitation of Big Data in the context of information-intensive industries and mainly in Tourism.  相似文献

体育赛事新媒体转播权之二分法律属性探讨     

张玉超 《武汉体育学院学报》2018,52(7):62-69

新媒体转播体育赛事带给观众观看体育赛事新体验同时，也面临着新媒体侵权现象频发，侵权纠纷增多等诸多问题，由于国内外对体育赛事转播权法律性质规定不太明确，体育赛事新媒体侵权的司法判决也不尽统一。主要采用逻辑思维法及案例分析法将体育赛事转播权和体育赛事节目分开讨论，分析了国内外法律、司法判决和专家学者对体育赛事转播权和体育赛事节目的法律性质与权利归属认定。研究认为：对体育赛事转播权法律性质分析应该根据体育赛事项目类型具体分析，对抗性体育赛事项目纳入商品化权保护，艺术性体育赛事纳入著作权保护；体育赛事节目依据独创性高低具有"制品"和"作品"两种观点，体育赛事节目应向体育产业发达的美国看齐，降低体育赛事节目独创性要求，将体育赛事节目视为作品纳入著作权法保护，体育赛事转播权权利主体归属于体育赛事组织、协会及联盟，体育赛事节目权利主体归属于获得授权的新媒体转播机构。  相似文献   

Media portrayal of a hidden problem: An analysis of Hong Kong newspaper coverage of child maltreatment in 2016     

《Child abuse & neglect》2018

The news media plays a vital role in providing child protection information and resources, shaping the public’s understanding and perceptions of child maltreatment, and exposing system failures and setting policy agendas. To date, little is known about how child maltreatment is portrayed in the media in societies where these issues remain largely hidden and under-recognized. The purpose of the present study was to systematically examine newspaper coverage on child abuse and neglect in Hong Kong in order to assess how child maltreatment is currently presented and framed within public discourse.A total of 579 newspaper reports relevant to child maltreatment from four local newspapers in 2016 were reviewed. Similar to prior findings, cases involving sexual abuse received disproportionately more attention compared with other maltreatment types. The vast majority of news reports focused on specific cases or events, and seldom discussed child maltreatment as a broader social issue. Differences in reporting style and media framing were also compared by newspaper credibility, and for free versus paid newspapers.As a mass communication tool, more guidelines are needed to formulate public messages about child maltreatment that can improve individual, community, and structural capacities to prevent, identify, and respond to children who are victimized by abuse and neglect. This is especially important in jurisdictions where no mandatory reporting framework exists to help identify vulnerable children, and where the majority of child maltreatment is brought to the attention of authorities by families and those living within the child’s community.  相似文献   

Understanding business interests in international large-scale student assessments: a media analysis of The Economist,Financial Times,and Wall Street Journal     

Gita Steiner-Khamsi  Margaret Appleton  Shezleen Vellani 《牛津教育评论》2018,44(2):190-203

The media analysis is situated in the larger body of studies that explore the varied reasons why different policy actors advocate for international large-scale student assessments (ILSAs) and adds to the research on the fast advance of the global education industry. The analysis of The Economist, Financial Times, and Wall Street Journal covers publications on ‘PISA’, ‘TIMSS’, and related search items over the period 1996–2016. The three media outlets vary in terms of ILSA reporting. The Economist and Financial Times tend to focus on PISA, whereas the Wall Street Journal pays greater attention to TIMSS than PISA. The content analysis of 59 articles yields interesting results about how the business-oriented readership of the three media outlets frames public education and why it sees education as a profitable business opportunity. The three most common narratives, reflecting the business logic, are the following: (i) public education is in crisis; (ii) there is no correlation between spending and education outcome; and (iii) school accountability, teacher performance, and decentralisation represent the most effective policies to improve the quality of education. Drawing on these three common narratives, the financial media outlets present a particular vision of how to improve education; a vision in which the private sector is supposed to play a major role.  相似文献
