Background and objective. In the last years, several motion analysis methods have been developed without considering representative contexts for sports performance. The purpose of this paper was to explain and underscore a straightforward method to measure human behavior in these contexts. Material and methods. Procedures combining manual video tracking (with TACTO device) and bidimensional reconstruction (through direct linear transformation) using a single camera were used in order to capture kinematic data required to compute collective variable(s) and control parameter(s). These procedures were applied to a 1vs1 association football task as an illustrative subphase of team sports and will be presented in a tutorial fashion. Results. Preliminary analysis of distance and velocity data identified a collective variable (difference between the distance of the attacker and the defender to a target defensive area) and two nested control parameters (interpersonal distance and relative velocity). Conclusions. Findings demonstrated that the complementary use of TACTO software and direct linear transformation permit to capture and reconstruct complex human actions in their context in a low dimensional space (information reduction).
This analysis of the 1953 creation of the Ministry of Health identifies the main actors involved, their interests, and the strategies they employed to reach their goals and influence the process of institutional change. Placing the process within the context of the era's specific political characteristics, the article identifies the predominant decision-making arena as well as emergence of this new, autonomous government agency for public health.
O artigo desenvolve uma análise historiográfica sobre alguns aspectos que marcaram a política social brasileira durante o primeiro governo de Getúlio Vargas (1930-45), privilegiando a saúde pública direcionada para a infância. Neste sentido, identifica certos princípios ideológicos que caracterizaram a política social varguista, para, em seguida, identificar sua influência na organização e funcionamento de dois serviços de saúde infantil: o de escolas-hospitais e o Laboratório de Biologia Infantil, destacando assim conexões entre ideologia e políticas públicas.
O texto apresenta pequenos trechos de entrevistas realizadas com médicos sanitaristas que atuaram em diversas instituições de saúde pública, principalmente no período compreendido entre 1930-1970. Os depoimentos descrevem formas de controle e combate a determinadas doenças, o formato de organização institucional existente e as concepções que orientavam a atuação profissional. Destaca-se em particular os relatos que descrevem a presença destes profissionais em diferentes regiões do país.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
