Abstract

Let 풰 be an algebra over the field 픽. We say that 풰 is two-sided zero product determined if every bilinear functional ϕ : 풰×풰→ 픽 the following holds: if ϕ(x,y) = 0 whenever xy = yx = 0, then there exist linear functionals F1 and F2 on 풰 such that ϕ(x,y) = F1(xy)+F2(yx) for all x,y ∈풰. We show that the unital triangular algebra 풯 = 풜ℳ0 ℬ is a two-sided zero product determined algebra if and only if 풜 and ℬ are two-sided zero product determined algebras, and then we get various results about this property for generalized triangular algebras and block upper triangular matrix algebras. We also provide an application of the main result to determine the structure of commutativity preserving maps at commutative zero products on triangular algebras. We note that some of the previous results about the two-sided zero product determined property have been generalized. [ABSTRACT FROM AUTHOR]

Abstract

As one of the key elements of mass communication process, the audience has always been of interest to mass media researchers and practitioners. The audience is important considering the realization of the economic goals of the media and the originality of the media content. This study used the ideas of previous studies in the field of communication and cultural studies, presented a model for understanding the public perception (PP), and modified the production of television programs using Delphi method according to the opinion of the experts that was finally approved by them. Experts' views and opinions were obtained with the questionnaire tool, the model was presented and with a total 78% of the opinions was confirmed in three parts of the accuracy of the components, relationship, and the explicitly of the model in describing the process. Thus, considering the fluidity and history of PP, it is suggested that PP should be constantly monitored and examined according to three factors - mass media contents, opinions of the experts, and published contents of social networks.
