The paper deals with the problem of acoustic correction in historic opera theatres with the auditorium layout in the form of a horseshoe with deep underbalcony cavities limited with a semicircular wall surface. Both geometry of the cavities and excessive sound absorption determine acoustic phenomena registered in this area of the hall. The problem has been observed in the Theatre of Opera and Ballet in Lviv, Ukraine, where acoustic tests were carried out, simulation calculations performed, and finally a diffusion panel worked out designed for the rear wall of the underbalcony space. Acoustic measurements carried out after installation of the diffusers revealed favourable changes in the sound strength factor G within the range of medium and high frequencies in the underbalcony and auditorium centre area. By replacing textile tapestry with diffusion panels, a significant reduction of sound absorption was achieved for the frequency range above 1 kHz and an increase of uniformity of acoustic parameters registered in the hall. The method presented in the paper can be applied in historic halls of the similar type as well as contemporary rooms where there is a need for correction of acoustic flaws related to sound focusing or the echo effect.
The article offers a presentation of one of the most influential currents in contemporary Marxism. The author claims that the vitality of Marxism comes from its ability to conceptualize ongoing transformations of capitalism, mainly the new forms of productions and appropriation of social wealth. The latter day Marxists propose a materialistic theory of common good. Its main concepts (primitive accumulation, enclosure of the common fields, productive labor and re-productive labor) are of Marxian origin, but they acquire a new sense in the new context. These reinterpretations are inspired by three basic philosophical and political sources: post-operaism, radical geography and bottom-to-top history. The article analyzes the connections between these concepts and the Marxism of common good.
The purpose of the article is to show how the TV-series—one of the most important forms of television production — is incorporated into the daily routines of the spectators. Michel de Certeau perspective of applied sociology of everyday life and critical reflection on everyday life is used as a theoretical framework. In the case of TV-series, the routines can take a form of: (1) “logging in” and “reading”” TV-series, (2)movement and sociability routines, and (3) discursive development of received meanings. “Soap opera experience” consists mainly of linguistic practices cultivated while watching the series, which is a modern form of storytelling, socializing, which changes the audiences’ view of reality, its social framework for evaluation and interpretation. A viewer is critical and active; they use consumption processes as an excuse to construct their own meanings and narratives, and negotiate the meaning of what is presented to them.
