Abstract Myrtaceae is a large and species-rich family of woody eudicots, with prevalent distribution in the Southern Hemisphere. Classification and taxonomy of species belonging to this family is quite challenging, sometimes with difficulty in species identification and producing phylogenies with low support for species relationships. Most of the current knowledge comes from few molecular markers, such as plastid genes and intergenic regions, which can be difficult to handle and produce conflicting results. Based on plastid protein-coding sequences and nuclear markers, we present a topology for the phylogenetic relationships among Myrtaceae tribes. Our phylogenetic estimate offers a contrasting topology over previous analysis with fewer markers. Plastome phylogeny groups the tribes Syzygieae and Eucalypteae and individual chloroplast genes produce divergent topologies, especially among species within Myrteae tribe, but also in regard to the grouping of Syzygieae and Eucalypteae. Results are consistent and reproducible with both nuclear and organellar datasets. It confronts previous data about the deep nodes of Myrtaceae phylogeny.
Abstract: Introduction The aim of this study is to identify the relation between the performance of a Leprosy Control Program (LCP) and the social network, in a municipality of the brazilian north/northeast region. Method The social network analysis methodology was used. The criteria for choosing the municipality were defined based on low performance of its LCP. The researchers visited the municipality to conduct observations, interviews and secondary data collection. The interviews began with the local coordinator of the program (LCP), the health secretary and two other coordinators. Further interviews were performed with the professionals cited by the “key-informants”, resulted by the use of the name generator technique. Sixteen interviews were conducted with professionals that work directly with the LCP, and it allowed the elaboration of six personal networks and three collective networks. From these, the scenario of the program in three stages were drew up, based on the social network structures: (I) problem identification, (II) statement of problem, and (III) restructuring. Results It was found a “double-centrality”, what means that the general coordinator of the LCP and general coordinator of Epidemiologic Surveillance shared functions in the program, with very strong personal ties. Other relations were characterized as strong or weak and professional. Conclusion It was identified a relation between the LCP performance and the different times of the social networks, which influenced the functionality of this.
Resumo Introdução Este artigo objetiva identificar a relação entre o desempenho de um Programa de Controle da Hanseníase (PCH) e a sua relação com a rede social, em um município brasileiro. Método Foram realizadas coleta de dados secundários, visitas para observação e entrevistas com o coordenador local do programa (PCH), o secretário de saúde, outros dois coordenadores e com profissionais por estes citados, seguindo a técnica de gerador de nomes. Dezesseis entrevistas originaram a elaboração de seis redes individuais e três coletivas, configurando três momentos: (I) identificação do problema, (II) demonstração do problema e (III) tentativa de reestruturação. Resultados Observou-se uma centralidade de cliques, em que o coordenador do PCH e o da Vigilância Epidemiológica compartilhavam funções no PCH, com fortes laços pessoais. As demais ligações identificadas foram caracterizadas como fortes ou frágeis, e profissionais. Conclusão Foi identificada relação entre o desempenho do PCH (indicadores) e os diferentes tempos das redes sociais, o que acabou por influenciar no funcionamento deste.
