Music Market

Forró is a typical musical style of the Northeast of Brazil, but it is spreading throughout the country, which leads to the expansion of the music market of the forró artists. Nowadays, much of the profits that these artists earn comes from shows, either by percentage of box office or by been an artist who get more people to buy tickets, thus raising the price of their shows. One factor that attracts more people to forró shows is how attractive to dancing are the songs played there. Echo Nest, an automatic evaluation tool for musical characteristics has created the danceability, metric that aims to inform how danceable a song is for any musical genre, not specifically to forró. This work aims to analyze the similarity between the values returned by the danceability and the opinions of consumers of forró, to determine if it could be used as a metric to indicate to artists and producers which songs they should play in a show or how to create more danceable songs that could attract more people to the shows and thus make more profit to their investors. The results showed that danceability fails to match the opinion of forró consumers about the attractiveness of songs to dance. According to literature, the degree of music’s syncopation is related to its attractiveness to dance, therefore, comparisons between various types of syncopation and consumer responses were also made to determine if there could exist any relationship between them regarding forró. The syncopation of bass, sung melody and tempo showed a positive correlation, and can be used as guidelines when composing new songs that are attractive to dance

The French Revolution

Giovanni Battista Viotti (b. 1755–d. 1824), the son of a blacksmith, was born in the village of Fontanetto Po, not far from Turin, where he completed his studies and began his career as a violinist. He died in London after a brilliant but checkered career as the most celebrated violinist of his time, as an opera theater and concert series director in Paris and London, and as a failed wine merchant. He was fêted by the crowned heads of Europe, including Frederick the Great, Catherine II of Russia, Marie Antoinette, and the Prince of Wales (later George IV of England). Forced to escape the French Revolution because of his royalist associations, he was later exiled from England for alleged revolutionary activities. Viotti’s life is instructive as an exemplum of musicians caught up in the social and economic upheavals of the French Revolution and its aftermath―the change from aristocratic and court patronage to the increasingly commercial, box office–centered institutions of the 19th century. For thirty years Viotti enjoyed an intimate friendship with an English family, the Chinnerys, that lasted until his death, and which in some ways became the mainspring of his existence. An extensive collection of their correspondence throws an extraordinarily vivid light on his life and career. Though he died in debt, having outlived his fame, Viotti, through his playing, his compositions, and his teaching, was arguably the most influential violinist who ever lived. His published oeuvre—consisting chiefly of violin concertos; sonatas for violin and keyboard; and string duets, trios, and quartets (and many arrangements thereof)—enjoyed enormous esteem and popularity in his time. Viotti’s musical style, thoroughly Italianate in its lyricism, reflects the evolution of the Classical style, from galant to pre-Romantic, but in an entirely original and unpredictable way. Scholarly study of Viotti and his works was practically nonexistent until the late 19th century, and remained scarce until well into the 20th century. Since the 1950s, however, and especially since the 1990s, scholarly studies—books and articles—have been published in ever-increasing numbers.

Usage Data

SummaryThe usability of interactive systems is an important attribute, especially for safety-critical devices like driver information systems. The functional complexity of such devices is increasing. Traditional user testing during development often fails to provide necessary data for an appropriate usability evaluation. In this work an approach for in-the-field usage data collection using the D'PUIS framework and automatic evaluation with the REVISER evaluation tool is introduced.

Different Cultures

The paper analyzes the phenomenon of world music and the preferences of music students from the Faculty of Arts of the University of Niš for this musical genre in the context of stimulating intercultural education. The research based on the descriptive method was conducted with the intention to obtain answers to questions about whether music students have knowledge/understanding of/for interculturality, to examine their attitudes towards different cultures, and whether they are ready to act against racial/cultural differences and prejudices. The results of this research were completed with the results of a survey, in which students evaluated selected examples of world music. This musical genre was chosen because in our opinion music is perceived not only as an autonomous artistic practice, but also as a representation of a particular culture, collective, and/or ethnic group. On the basis of the results, we tried to determine the students' reactions to the musical characteristics of the closer and distant cultural areas as well as their willingness to accept musical, linguistic and cultural differences in the context of the still dominant presence of the West European  musical art in the process of academic education.

Summary: The concept of “sense of coherence” (SOC) has been widely recognized since it was first introduced by Antonovsky. The originality and usefulness of the SOC scale and its relation to other psychosocial measures has been the subject of lively debate. The aim of this paper was to test for associations between SOC and work-related psychosocial factors (mainly the Job Demand-Control model), general living conditions, education, and social network factors. Cross-sectional data from a population-based sample of 1782 rural males from nine counties in Sweden were analyzed with a multiple regression technique. The subjects were occupationally active at inclusion and the mean age was 50 years (range 40-60). SOC was assessed with the original 29-item questionnaire. Psychosocial variables and lifestyle factors were assessed using questionnaires and structured interviews. The mean SOC among the subjects was 152.3 (standard deviation, 19.4). A strong negative correlation was found between SOC and job demand, whereas a positive correlation with job control was demonstrated. A positive correlation with general living conditions and with social support was also found. However, there was no correlation to education and occupation. Thus, SOC was shown to be strongly correlated to work-related psychosocial factors and social support, but independent of sociodemographic factors.

Locus of control (LOC), safety attitudes, and involvement in hazardous events were studied in 205 Indian Army aviators using a questionnaire-based method. A positive correlation was found between external LOC and involvement in hazardous events. Higher impulsivity and anxiety, and decreased self-confidence, safety orientation, and denial were associated with a greater number of hazardous events. Higher external LOC was associated with higher impulsivity, anxiety, and weather anxiety and with lower self-confidence, safety orientation, and denial. Internal LOC was associated with increased self-confidence, safety orientation, and denial. Hazardous events and self-confidence were higher in those involved in accidents than those not involved in accidents. Future research needs to address whether training can effectively modify LOC and negative attitudes, and whether this would cause a reduction in, and better management of, human errors.
