The new role of the mass media in the construction of sport and Olympic values

This paper was presented in the International Symposium on Toward the Creation of New-Sport Cultures, undertaken in Osaka, Japan, in January 28, 1996. The main purpose is to make an interpretation of the cultural values of sport and Olympism in contemporary society, considering the enormous influence that the media have on them.

The mass media destabilizes the cultural homogenous regime in Axelrod`s model

An important feature of Axelrod`s model for culture dissemination or social influence is the emergence of many multicultural absorbing states, despite the fact that the local rules that specify the agents interactions are explicitly designed to decrease the cultural differences between agents. Here we re-examine the problem of introducing an external, global interaction-the mass media-in the rules of Axelrod`s model: in addition to their nearest neighbors, each agent has a certain probability p to interact with a virtual neighbor whose cultural features are fixed from the outset. Most surprisingly, this apparently homogenizing effect actually increases the cultural diversity of the population. We show that, contrary to previous claims in the literature, even a vanishingly small value of p is sufficient to destabilize the homogeneous regime for very large lattice sizes.

On-line mass spectrometry of the electro-oxidation of methanol in acidic media on tungsten carbide

The electro-oxidation of methanol at supported tungsten carbide (WC) nanoparticles in sulfuric acid solution was studied using cyclic voltammetry, potentiostatic measurements, and differential electrochemical mass spectroscopy (DEMS). The catalyst was prepared by a sonochemical method and characterized by X-ray diffraction. Over the WC catalyst, the oxidation of methanol (1 M in a sulfuric acid electrolyte) begins at a potential below 0.5 V/RHE during the anodic sweep. During potentiostatic measurements, a maximum current of 0.8 mA mg(-1) was obtained at 0.4 V. Measurements of DEMS showed that the methanol oxidation reaction over tungsten carbide produces CO2 (m/z=44); no methylformate (m/z=60) was detected. These results are discussed in the context of the continued search for alternative materials for the anode catalyst of direct methanol fuel cells.

Crime, Mass Media and the General Public in Lithuania

The project investigated the presentation of crime in the Lithuanian media and its possible impact on the general public's understanding of crime-related problems in society. Dobryninas concentrated on three main aspects of this problem: the development of the image of crime in the Lithuanian press and television, journalists' principles in presenting crime-related information, and the public attitude to the presentation of crime in the media. A content analysis of national newspapers from the period of 1992-1997 showed not only increasing interest in crime problems, but also the distorted nature of the image of crime in the media. In-depth interviews with Lithuanian journalists demonstrated that they understood their role in presenting crime-related information firstly as providing information oriented to high public demand, although at the same time they did not deny the commercial and entertainment aspects of crime reporting. Readership and audience research illustrated the clear influence of the media on the public understanding of crime problems in society. However, the virtual image of crime did not greatly affect the system of values and beliefs of Lithuanians, nor did it challenge their insistence that problems of crime could and should be managed within the framework of a civil and open society.
