Fereshteh Didegah  Niels Mejlgaard  Mads P. Sørensen 《Journal of Informetrics》2018,12(3):960-971

This study explores science communication on Twitter by investigating a sample of tweets referring to academic papers in five different scientific fields. The specifications of science communicators on Twitter, the characteristics of those who initiate actions (by tweeting), the extent and quality of reactions (retweeting), individual and group interactions, and the distribution of tweets across types of engagement in the process of science communication (i.e., dissemination, consultation, and evaluation) were explored. A broad array of actors is involved in the communication of science on Twitter, with individual citizens and individual researchers playing an important role. In principle, this is promising for creating direct interaction, which can be difficult through more traditional mass media. The vast majority of communication activities regarding academic papers is undigested dissemination with almost no sign of debate, contestation, or collective reflection. Another general finding of this study is that bot accounts play a major role in the science communication landscape on Twitter.  相似文献   

The effect of the integration of students with special educational needs: Evidence from Chile     

《International Journal of Educational Development》2020

This paper studies the effect of the integration of students with Special Educational Needs (SEN) on the academic achievement of their peers without SEN. This achievement is measured using performance in standardized reading and mathematics tests. The study also evaluates the effect of a policy that recognizes and increases resources for special educational needs that had not yet been considered and improves education provision protocols for students with SEN. Using administrative data and standardized test scores, we constructed a panel that follows a cohort of students before and after the reform, determining for each individual and year whether the class to which he/she belongs has any students with SEN. Our identification strategy employs panel data with fixed effects at the school, individual, and time levels. Estimates show that, on average, having a peer with SEN in the classroom has a negative effect on the academic performance of students without SEN. However, these effects are small and decrease, or even vanish, once better inclusion policies are in place. These results suggest that the effect on peers is almost totally canceled when more resources are provided and when adequate treatment and support protocols are implemented.  相似文献

Prejudices Unshelved: Variation in Attitudes toward Controversial Public Library Materials in the General Social Survey, 1972–2014     

Jeremy Brett  Mary E. Campbell 《Public Library Quarterly》2016,35(1):23-36

Using the General Social Survey from 1972–2014, we examine variation in attitudes toward retaining controversial materials in libraries. Previously controversial topics have become much more widely accepted. We find that other controversies remain, showing how global conflicts become intertwined in local cultural controversies, and how the perceived threat from particular groups informs public concern with disseminating information from those groups. We find that more frequent library users are somewhat less likely to want to remove controversial books from the shelves, although some of these relationships are explained by variation in the respondent’s age, race, and other characteristics.  相似文献   

Using Political Journalists’ Definitions of Public Opinion to Predict Source Use in Political News     

Jennifer Hoewe 《Communication Research Reports》2016,33(3):247-252

This study examined political journalists’ definitions of public opinion and how these definitions influence the structure of political news stories. After considering prior conceptualizations of public opinion, a scale of two distinct definitions of public opinion was created, consisting of the optimist’s and the pessimist’s definitions. Using a survey of political journalists in the United States, these public opinion definitions were significant predictors of the use of particular sources in political news stories. Importantly, the two definitions had opposite influences on the use of opinion polls, shedding light on the discrepancy in use and perception of poll results in political news.  相似文献
