The article examines the issue of globalization, along with its contradictions and the ways in which it guides and shapes specific situations within the Amazon's present-day reality, while simultaneously engendering the uniformization of economic production and the valorization of cultural differences. The discussion explores the nuances of implementing a massified, standardized productive base...

Recognizing different features of a waveform to later recompose the music that was originally present in the signal is a difficult task. There are numerous fields of application where these techniques are known to be useful including music authoring, digitizer design, automatic music transcription. There are many different methods that can be used for this purpose giving somehow inadequate qual...

This paper presents a Maximum Likelihood approach to multiple fundamental frequency (F0) estimation in each frame of music signals in the frequency domain. The frequencies and amplitudes of the spectral peaks are viewed as observations, and the F0s are viewed as parameters to be estimated. The proposed method considers the potential errors in the peak detection algorithm and treats each peak as...

Departing from a Lockean illustration in the context of the history of the notion of Self, this article presents a discussion on dialogism as an effort to overcome ethnocentric views of human psychological phenomena. Dialogical approaches in psychology focus tensions between different viewpoints in face of an object of social representation (Marková, 2006). It is assumed that the socio-cultural...

This article presents a new approach to sound source separation. The introduced algorithm is based on spectral modeling of real instruments. The separation of independent sources is carried out by dividing the energy of the mixture signal based on these instrument models. This way it is possible to regain some of the information that was lost when the independent sources were mixed together int...

In recent years linguistic research has turned increasing attention to covert/overt strategies to modulate authorial stance and positioning in scientific texts, and to the recipients' response. This study discussed some theoretical implications of the use of rhetoric in scientific communication and analysed qualitative data from the authoritative The Cognitive Neurosciences III (2004) volume. I...
