A música do ponto de vista do nativo: um ensaio bibliográfico

O presente artigo busca caracterizar as diferentes posições que a musicologia comparada, na primeira metade do século XX, e a etnomusicologia, sua herdeira na segunda metade do século, desenvolveram a respeito do pensamento sobre a música nas culturas que estudaram. Se, em um primeiro momento, a percepção da (in)existência desse pensamento esteve marcada pela oposição à teoria musical ocidental, o reconhecimento da diversidade de seu conteúdo e, depois, de sua forma foi gradualmente conquistando a disciplina. A tal ponto que hoje se pode perguntar, dialeticamente, se, para além da diversidade do pensamento sobre a música, não há uma unidade do pensamento musical como modalidade cognitiva característica da espécie.

Can varying the number of teams in a shift schedule constitute a preventive strategy?

OBJECTIVE: The study examines the implications for shiftworkers of applying different numbers of teams in the organization of shiftwork. METHODS: The participating operators came from five different companies applying continuous shift rotation systems. The companies shared the same product organization and a common corporate culture belonging to the same multinational company. Each company had a shift system consisting of four, five or six teams, with the proportion of shifts outside day work decreasing as the number of teams increased. Questionnaire and documentary data were used as data sources. RESULTS: Operators in systems with additional teams had more daywork but also more irregular working hours due to both overtime and schedule changes. Operators using six teams used fewer social compensation strategies. Operators in four teams were most satisfied with their work hours. Satisfaction with the time available for various social activities outside work varied inconsistently between the groups. CONCLUSIONS: In rotating systems the application of more teams reduces the number of shifts outside day work. This apparent improvement for shiftworkers was counteracted by a concomitant irregularity produced by greater organizational requirements for flexibility. The balance of this interaction was found to have a critical impact on employees.
