The Formation of Swedish Media Studies, 1960–1980     

Mats Hyvönen  Pelle Snickars  Per Vesterlund 《Media History》2018,24(1):86-98

Around 1960, the politics of the emerging media society in Sweden tended to fixate the formative functions of mass communication. The monopoly of public service broadcast media, press subsidies and new tendencies in film policy were some of the issues around which uncertainty prevailed. New methods to provide reliable data were sought by politicians, since empirical facts were required as arguments for an updated media policy. This article examines the different ways that the field of media studies was introduced in Sweden between 1960 and 1980. We argue that Swedish academic media studies departed from, and emerged within, a rather diffuse borderland between industry, politics and academia. The formation of national media research in Sweden can partly be seen as an effect of politicians and the media industry wanting to be better informed on issues such as media influence, media ownership and the habits and composition of the media audience.  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
