ABSTRACT
RESUMO Este artigo tem por objetivo identificar os fatores que influenciam a eficiência na aplicação dos recursos destinados à Atenção Básica nos municípios brasileiros. Para isso, utilizou-se o modelo de regressão beta inflacionado, uma vez que a variável dependente apresenta valores no intervalo (0,1]. De acordo com os resultados, o índice Firjan de desenvolvimento municipal na saúde e serviços de saneamento básico são fatores que influenciam positivamente a eficiência média na Atenção Básica de um município. Por outro lado, o gasto per capita de um município, em Atenção Básica, exerce efeito negativo na eficiência média.
ABSTRACT This article aims to identify the factors that influence the efficiency in the application of resources destined to Primary Health Care in brazilian municipalities. To this end, the inflated beta regression model was used, since the dependent variable presents values in the interval (0,1]. According to the results, the Firjan Index of Municipal Development in health and basic sanitation services are factors that positively influence the average efficiency in the Primary Health Care of a municipality. On the other hand, the per capita expenditure of a municipality, in primary care, exerts a negative effect on the average efficiency.
ABSTRACT
Positron annihilation spectroscopy (PAS) was used to examine the effect of defined Cd-rich and Te-rich annealing on point defects in Cl-doped CdTe and Ge-doped CdZnTe semi-insulating single crystals. The as-grown crystals contain open-volume defects connected with Cd vacancies . It was found that the Cd vacancies agglomerate into clusters coupled with Cl in CdTe:Cl, and in CdZnTe:Ge they are coupled with Ge donors. While annealing in Cd pressure reduces of the density, subsequent annealing in Te pressure restores . The CdTe:Cl contains negatively-charged shallow traps interpreted as Rydberg states of A-centres and representing the major positron trapping sites at low temperature. Positrons confined in the shallow traps exhibit lifetime, which is shorter than the CdTe bulk lifetime. Interpretation of the PAS data was successfully combined with electrical resistivity, Hall effect measurements and chemical analysis, and allowed us to determine the principal point defect densities.
