We started with the theoretical background and we analyzed the audiences of the TV channels dedicated to sports. Media and violence is a well-known subject, and many theorists have analysed it but little research has been conducted about the effects that violence in sport news may have on people or society. Therefore, the aim of this study is to provide insights into these effects, to try to demonstrate that today＇s sports news does not focus on pcrformancc any more, but they have become a spectacle of violence and gossip. After reviewing the literature in order to gain a perspective on this topic, we focused on the complex reconstructive and subjective nature of news rcception, the different ways the audience constructs meaningful intcrpretations from the news, exposure to news and the construction of violent images of reality.展开更多

Methods MfERG was performed in 66 patients （ 66 eyes） which were grouped into ： emmetropes （ n = 22 ） as the control eye ; high myopes without fundus lesions （ corrected visual acuity ≥ 1. 0, n = 15 ） ; and fellow eyes of high myopics with RRD （n = 29 ）. The first-order kernels N1, P1, N2 response density and latency were analyzed. Results When compared with the emmetropes group, the high myopes group had significantly reduced N1 , PI , and N2 wave response densities in rings 1 to 6 （ P 〈 0. 05 ）, delayed N1 wave latency in rings 3 to 6, and P1 wave latency in rings 3 to 5 （ P 〈 0. 05 ）. The fellow eyes group had significantly reduced N1, P1, and N2 wave response densities in rings 1 to 6 and significantly delayed N1 and P1 wave latencies in rings 3 to 6 （ P 〈0. 05） compared with the emmetropes group. Compared with the high myopes group, P1 wave response densities in rings 1 to 6, N1 wave response densities in rings 1,3, 4, and 6, and N2 wave response density in ring 1 were significantly decreased in the fellow eyes group （ P 〈 0. 05 ） ; whereas there were no significant differences in latencies between the two groups （P 〉0.05）. Conclusion MfERG can sensitively assess the early changes in visual function in fellow eyes in patients with RRD.展开更多
