Os estudos de recepção como modelo multidimensional: A negociação de estereótipos de etnicidade e género

Este artigo pretende analisar a multidimensionalidade do modelo de estudos de recepção, apresentando, para esse efeito, os resultados de dois projectos de investigação. Enquanto o primeiro projecto incide sobre a reacção de imigrantes brasileiras à representação das suas conterrâneas nos media portugueses, o segundo debruça-se sobre a reacção das portuguesas à representação do feminino enquanto sujeito e objecto de notícia na imprensa nacional. Com base num modelo multidimensional dos media que divide a cultura mediática em categorias de fidelidade representativa, espaço público agonístico e funcionalidade dos media, procurase explorar o modo como os estereótipos étnicos e de género são assimilados no quotidiano mediante a adopção de leituras preferenciais, negociadas ou opositivas. Estas interpretações de significados veiculados pelos media indicam que as redefinições de identidades étnica e de género são condicionadas pelo imaginário bem como por imperativos de ordem económica.

Robosonic: Randomness-Based Manipulation of Sounds Assisted by Robots

In this text, we intend to explore the possibilities of sound manipulation in a context of augmented reality (AR) through the use of robots. We use the random behaviour of robots in a limited space for the real-time modulation of two sound characteristics: amplitude and frequency. We add the possibility of interaction with these robots, providing the user the opportunity to manipulate the physical interface by placing markers in the action space, which alter the behaviour of the robots and, consequently, the audible result produced. We intend to demonstrate through the agents, programming of random processes and direct manipulation of this application, that it is possible to generate empathy in interaction and obtain specific audible results, which would be difficult to otherwise reproduce due to the infinite loops that the interaction promotes.

A System Dynamics-Based Simulation Experiment for Testing Mental Model and Performance Effects of Using the Balanced Scorecard

This study develops a theoretical model that explains the effectiveness of the balanced scorecard approach by means of a system dynamics and feedback learning perspective. Presumably, the balanced scorecard leads to a better understanding of context, allowing managers to externalize and improve their mental models. We present a set of hypotheses about the influence of the balanced scorecard approach on mental models and performance. A test based on a simulation experiment that uses a system dynamics model is performed. The experiment included three types of parameters: financial indicators; balanced scorecard indicators; and balanced scorecard indicators with the aid of a strategy map review. Two out of the three hypotheses were confirmed. It was concluded that a strategy map review positively influences mental model similarity, and mental model similarity positively influences performance.
