Mensurando os impactos diretos e indiretos do capital humano sobre o crescimento
Nakabashi, Luciano;Figueiredo, Lízia de;
Economia Aplicada , 2008, DOI: 10.1590/S1413-80502008000100007
Abstract: the objective of this study is to evaluate the different channels wherein human capital affects income per worker level and growth. the empirical analysis is based in a model that incorporates several channels in which human capital affects the rate of income per worker growth: 1) improving the marginal productivity of labor; 2) through creation of technology; and 3) diffusion of technology. the consideration of several channels wherein human capital affects income is due to the complexity of the relationship between these two variables. therefore, if we rule out any channel we can incur in model specification errors.

Coelho, Rodrigo Lara Pinto;Figueiredo, Lízia de;
Revista Brasileira de Economia , 2007, DOI: 10.1590/S0034-71402007000300003
Abstract: this paper attempts to ascertain which of the convergence hypotheses - absolute, conditional or club - best describes the dynamics of the brazilian municipalities income over the period 1970-2000. the results based on the regression tree method and on robustness tests demonstrate the importance of initial conditions on the determination of municipalities income growth rate, which suggests the dominance of the club convergence hypothesis over the other two.

Abstract: health status can affect economic growth through at least three mechanisms: 1) directly, through the relationship between health status and individual earnings, 2) indirectly, through the effect of health on levels of education, and 3) through physical capital investments. poor health status causes considerable losses in individual income by decreasing labor productivity, numbers of hours worked, and participation in the labor force. these losses can affect a population's level of wealth and contribute to decreased social well-being. the main goal of this study is to assess the relationship between health and economic growth among the brazilian states between 1991 and 2000. in order to take into account the different epidemiological and morbidity profiles observed among the states, several health measures were selected such as infant mortality rate, hospital mortality rate in the public healthcare system due to perinatal complications, and proportion of deaths from selected causes (vascular diseases, diabetes, cancer, aids and other communicable diseases, homicides and ill-defined causes). our main findings show that in brazil health correlates positively with economic growth. we also found that decreases in infant mortality rates are closely associated with higher rates of economic growth. we found a significant negative relationship for health indicators that are related to poverty, less access to health care services and deaths from avoidable causes, such as communicable diseases and hospital mortality rates due to perinatal complications. in contrast, we found a positive and significant correlation between the proportion of deaths from diabetes and cancer, on the one hand, and economic growth, on the other.

Abstract: The Apipucos Reservoir is located in Pernambuco-Brazil. Several districts of the metropolitan area use this reservoir to dispose of rubbish, waste and sewage. Dating sediments uses the 210Pb from the atmosphere. 210Pb is a daughter of the 222Rn, which emanates from the soil but is different from that contained in the sediment, which is in balance with the 226Ra. The chosen model for dating sediments depends on certain conditions: in environments where the amount of sediment can vary, the Constant Rate of Supply (CRS) model is adopted. In environments where the sediments can be considered to be constant, a Constant Initial Concentration (CIC) model is applied. A 70 cm long and 5 cm internal-diameter wide core was used for sediment sampling. Samples were dried at 105 °C, and about 5 g dry material was dissolved with acids. The 210Pb and 226Ra content was determined by their radioactive descendants’ concentrations. For the second sampling point, both models could be used. The results showed an increase in sedimentation rate over the last 50–60 years. We could conclude that the top sediment interval had been there 30 years ago. We could decide that the CRS was the best applicable model.

Abstract: this study is a proposal for a scientific contribution to the understanding of the interrelationships between density population of soil microorganisms associated with seasonal microclimatic variability in tropical rainforest, also considering a case study of extreme event. some organisms, especially soil microorganisms are very sensitive to small variations in microclimate (sun light, temperature, soil moisture, wind, sensible heat, latent heat, etc). surely these conditioning factors are important for understanding the spatial distribution of these living things in natural ecosystems, inhabited by a variety of microorganisms (mushroom and bacteria) that were studied for their distribution and density, using the technique of "pour plate" count of "petri plates" following the methodology utilized for de-polli and guerra, described by clark. this study was conducted in two experimental areas ppbio (natural rainforest area) and esecaflor (one acre covered area to simulate drought) in caxiuan?-pa, with continuous measurements of microclimatic variables such as temperature, humidity and rainfall, and the evaluation of spatial and temporal distribution patterns of the species abundance and richness, to establish a monitoring procedure of soil fungi and bacteria associated with climate variability in the national forest caxiuan?. the experimental areas are predominantly yellow latossol soils. microbiological analysis showed that fungi developed better during the dry season and bacteria during rainy season, and their populations decrease with depth, except in a changed environment. correlation values between seasonal variation of fungi and bacteria population and varying temperature and soil humidity were satisfactorily for any season in both sites.
