Exploring different approaches for music genre classification

In this letter, we present different approaches for music genre classification. The proposed techniques, which are composed of a feature extraction stage followed by a classification procedure, explore both the variations of parameters used as input and the classifier architecture. Tests were carried out with three styles of music, namely blues, classical, and lounge, which are considered informally by some musicians as being “big dividers” among music genres, showing the efficacy of the proposed algorithms and establishing a relationship between the relevance of each set of parameters for each music style and each classifier. In contrast to other works, entropies and fractal dimensions are the features adopted for the classifications.

Music tempo's effect on exercise performance: comment on dyer and mckune

Dyer and McKune (2013) stated that music tempo has no influence on performance, physiological, and psychophysical variables in well-trained cyclists during high intensity endurance tasks. However, there are important limitations in the methodology of the study. The participants'music preferences and tempo change were not well measured. It is not possible to affirm that music tempo does not influence athletes'performance. Potential areas of future research include: (a) use of instruments to assess the qualities of music; (b) standardizing music of tempo according to exercise type (e.g., running, cycling, etc.); (c) considering training level of the participants (i.e., athletes and non-athletes); and (d) use of instruments to assess concentration during exercise.

Acute auditory stimulation with different styles of music influences cardiac autonomic regulation in men

No clear evidence is available in the literature regarding the acute effect of different styles of music on cardiac autonomic control. The present study aimed to evaluate the acute effects of classical baroque and heavy metal musical auditory stimulation on Heart Rate Variability (HRV) in healthy men. In this study, HRV was analyzed regarding time (SDNN, RMSSD, NN50, and pNN50) and frequency domain (LF, HF, and LF / HF) in 12 healthy men. HRV was recorded at seated rest for 10 minutes. Subsequently, the participants were exposed to classical baroque or heavy metal music for five minutes through an earphone at seated rest. After exposure to the first song, they remained at rest for five minutes and they were again exposed to classical baroque or heavy metal music. The music sequence was random for each individual. Standard statistical methods were used for calculation of means and standard deviations. Besides, ANOVA and Friedman test were used for parametric and non-parametric distributions, respectively. While listening to heavy metal music, SDNN was reduced compared to the baseline (P = 0.023). In addition, the LF index (ms(2) and nu) was reduced during exposure to both heavy metal and classical baroque musical auditory stimulation compared to the control condition (P = 0.010 and P = 0.048, respectively). However, the HF index (ms(2)) was reduced only during auditory stimulation with music heavy metal (P = 0.01). The LF/HF ratio on the other hand decreased during auditory stimulation with classical baroque music (P = 0.019). Acute auditory stimulation with the selected heavy metal musical auditory stimulation decreased the sympathetic and parasympathetic modulation on the heart, while exposure to a selected classical baroque music reduced sympathetic regulation on the heart.

Pre-task music improves swimming performance

The purpose of this study was to investigate the effects of pre--task music on swimming performance and other psychological variables. A randomized counterbalanced within--subjects (experimental and control condition) design was employed. Eighteen regional level male swimmers performed two 200m freestyle swimming time trials. Participants were exposed to either 5min of self--selected music (pre--task music condition) or 5min of silence (control condition) and, after 1 minute, performed the swimming task. Swimming time was significantly shorter (--1.44%) in the pre--task music condition. Listening to pre--task music increased motivation to perform the swimming task, while arousal remained unchanged. While fatigue increased after the swimming task in both conditions, vigour, ratings of perceived exertion and affective valence were unaltered. It is concluded, for the first time, that pre--task music improves swimming performance.

A modular approach to study protein adsorption on surface modified hydroxyapatite

Biocompatible inorganic nano- and microcarriers can be suitable candidates for protein delivery. This study demonstrates facile methods of functionalization by using nanoscale linker molecules to change the protein adsorption capacity of hydroxyapatite (HA) powder. The adsorption capacity of bovine serum albumin as a model protein has been studied with respect to the surface modifications. The selected linker molecules (lysine, arginine, and phosphoserine) can influence the adsorption capacity by changing the electrostatic nature of the HA surface. Qualitative and quantitative analyses of linker-molecule interactions with the HA surface have been performed by using NMR spectroscopy, zeta-potential measurements, X-ray photoelectron spectroscopy, and thermogravimetric analyses. Additionally, correlations to theoretical isotherm models have been calculated with respect to Langmuir and Freundlich isotherms. Lysine and arginine increased the protein adsorption, whereas phosphoserine reduced the protein adsorption. The results show that the adsorption capacity can be controlled with different functionalization, depending on the protein-carrier selections under consideration. The scientific knowledge acquired from this study can be applied in various biotechnological applications that involve biomolecule-inorganic material interfaces.

Narrativa audiovisual complexa: modular narratives e database narratives

Procura-se nesse trabalho expor as considerações levantadas sobre a modularidade e a temporalidade do filme Pulp Fiction (1994), de Quentin Tarantino, enquadrada por Simons (2008) nas categorias de narrativa audiovisual complexa denominadas modular narratives e database narratives. Com Ricoeur (1983), discutiu-se a sua organização temporal a partir do conceito de tríplice presente em Santo Agostinho, enquanto com Propp (1970) e Cameron (2008) o cará- ter modular dessa narrativa.

A percepção visual visando a continuação gráfica na repetição modular do design de superfície

This article narrates from experiences in the classroom, the use of visual perception in the search for the solution of a basic problem of modular repetition, embodied by the lack of continuity in the elements that shape the design surface. Although Wong (1998) approach emphasizes the intuitive and intellectual approach as different parameters for building visual compositions, we list both as participants in the same focus, where the solution starts from the sensory stimulation.

Use of music and play in pediatric nursing care in the hospital context

Objective. To identify and analyze scientific publications on the use of music and play in pediatric nursing care in the hospital context. Method. In this bibliographic study, papers were sought that were published in Portuguese or English between 2004 and 2009 and included the descriptors: hospitalized child, childhood, child recreation, nursing team, nursing, pediatric nursing, alternatives therapies, music, music therapy, play and playthings, play therapy, playing. For the review, the bibliographic databases used were MEDLINE, ScIELO and LILACS. Results. Seventeen publications were obtained, among which: 59% adopted a quantitative method; mainly nursing developed the activities (88%); per type of article, reviews on the theme and assessments of clinical changes associated with the use of music and play were frequent (59% and 18%, respectively); and the utility of this kind of therapies in nursing care is acknowledged (94%). Conclusion. Play and music are useful therapies that can be used in nursing care for pediatric patients.

Da coordenação modular à construção modular: estudos de caso

The presented work aimed to present the Modular Construction scenario, relating it to the fundamentals assumptions on the Modular Coordination Theory. The presentation of this theory, its historical development, its scope and tools, were conceived to further, show how the applicability on the conceptual and design phases is done. Also, studies cases are shown, in order to illustrate didactically how this process occurs. Basing on these studies, considerations are made about the use of modulation in projects in Brazil, at the expense of what happens on the international scenario, to highlight the importance of Modular Coordination for raising the standards of construction quality and rationality in the country
