Multimedia for Learning in Economy and Cybernetics

The use of many multimedia channels in order to bring information to target groups is not something new. What is new is related to how these channels are exploited by mixing techniques and technologies. We realized an online questionnaire to identify the multimedia techniques/tools that have impact on user’s satisfaction. We used comparative statistical analyses (Levene’s test) to observe if there are any significant differences between multimedia users and non-multimedia users. We identified that the preferred techniques are: the presence of a narrator, the existence of some suggestive images, slides and demos. These are only some factors that we identified. We studied also the influence of features as: access to, scenario type, interactivity, flexibility, additional options and effects and time dependency. We determined that the existence of useful links is an important factor for overall satisfaction of the user with multimedia materials.

Once Again on Negative Externalities: Between Regulation and Liability

Abstract The ideological debate on public government involvement in environmental issue is ever-topical as resource exploitation affects the quality of the natural environment. Considering the two issues involved in the analysis of externalities, social welfare and property rights, we intend in this paper to develop on the problems related to the implications of the two doctrinal approaches in limiting negative externalities, with a special focus on the recent events in the Romanian economy. The most important conclusion of this study is the necessity of increasing the moral responsibility of all stakeholders and of strengthening the rule of law. As Peter Lewin in his paper, Pollution Externalities: Social Cost and Strict Liability, concluded, “if we can avoid making a virtue out of the need to compromise, we may succeed in the future in reducing the need to compromise”.
