We compare economic efficiencies in Brazil, India, and China, where economic efficiency measures the gap between potential and actual output for a given input combination and technological factor. We use stochastic production frontier models to measure the contributions of factors of production and technology to growth and estimate non-positive error terms that capture production inefficiencies in each country. The results suggest that China and India had relatively inefficient production in the early 1980s but have since improved production efficiency substantially. In the same period, production efficiency in Brazil has lagged those of China and India. The gap between Brazil??s production efficiency and those of its Asian peers has narrowed in recent years. However, production remains more efficient in China and India, supporting more rapid growth in these countries relative to Brazil.  相似文献

As part of a long-term project on Northeastern Brazilians, population genetic data were obtained from 323 unrelated individuals from the state of Paraíba. The loci studied were CSF1P0, TPOX, TH01, vWA, D16S539, D7S820, D13S317, D18S51, D21S11, D8S1179, F13A01, F13B and LPL. Their distributions are in Hardy-Weinberg equilibrium. Forensic parameters were calculated and a comparison was made with geographically nearby populations.  相似文献

The drug trafficking is one of the most serious problems related to the Public Safety in Brazil, especially in the most populous areas of the country, as is the case of the city of São Paulo. In this work, it was developed a methodology that can help tracking the traffic routes of marijuana samples seized in the city of São Paulo, based on stable carbon and nitrogen isotopes, which are related to the climate and plant growth conditions. A model to classify the origin of unknown samples was built using linear discriminant analysis based on about 150 samples apprehended in the main producing regions of the country. Results for 76 samples seized in the city of São Paulo showed that most of them were cultivated in a humid region with the same origin as those from Mato Grosso do Sul. The provenance of 13 outliers samples from Northeast region (an important producing region) also were evaluated and some of them presented same profile of those from Mato Grosso do Sul, pointing to the existence of the traffic routes between the Northeast and Midwest region, probably as a consequence of the intensive field raids by Brazilian Federal Government since 1999.  相似文献

The article analyzes the census records for Sao Cristovao in 1870 to determine the proportions of single mothers in the population and whether they were living in female-headed households, as companheiras in male-headed households (in consensual union), or as agregadas or dependent members of a household headed by someone else, who was not the sexual partner of the single mother. The socio-economic and racial characteristics of the single mothers are also compared to each other and to the married population. The data suggest that approximately one-third of single Brazilian mothers and their children were living in informal two-parent relationships. These women were not substantially different from the two-thirds of single mothers who were living either as female heads of households or as dependents in other households, in terms of race, age, or occupation. Women who were female heads of households were somewhat older than the average single mother in a consensual union, and the women living in dependent situations were slightly younger. The greatest difference between these two groups of women is that many married mothers had no occupations while the vast majority of single mothers listed professions. The baptismal records of illegitimate babies suggest that the vast majority of them had ritual kinfolk, and some were grandparents involved in their baptisms and perhaps also in their daily living arrangements.  相似文献

In 2007, Brazil entered the European Union’s (EU) list of strategic partners; a token of recognition of the place Brazil occupies in current global affairs. Although promoting bilateral environmental convergence is a stated priority, cooperation between the EU and Brazil in this policy field is largely under-researched, raising interesting questions as to whether the current state of play could support EU claims for the normative orientation of its external environmental policy. Through an analysis of partnership activities in the fields of deforestation and biofuels, we suggest that while normative intentions may be regarded as a motivating force, critically viewing EU foreign environmental policy through a ‘soft imperialism’ lens could offer a more holistic understanding of the current state of bilateral cooperation. While the normative power thesis can be substantiated with regard to deforestation, we argue that by erecting barriers to shield its domestic biofuels production, the EU is placing trade competitiveness and economic growth above its normative aspirations. Subsequently, the partial adoption of sustainable development as an EU norm leads to policy incoherence and contradictory actions.  相似文献

The black soldier-fly (Hermetia illucens) is a generalist detritivore which is commonly present in corpses in later stages of decomposition and may be useful in forensic entomology. This paper describes the estimation of the postmortem interval (PMI) based on the life cycle of the black soldier-fly in a case in northern Brazil. A male child was abducted from his home and 42 days later his corpse was found in an advanced stage of decay. Two black soldier-fly larvae were found associated with the body. The larvae emerged as adults after 25-26 days. Considering the development cycle of H. illucens, the date of oviposition was estimated as 24-25 days after abduction. Since H. illucens usually (but not always) colonizes corpses in more advanced stages of decay, this estimate is consistent with the hypothesis that the child was killed immediately after abduction.  相似文献

Allele frequency distributions and population data for 12 Y-chromosomal short tandem repeats (STRs) included in the PowerPlex®Y Systems (Promega) were obtained for a sample of 200 healthy unrelated males living in São Paulo State (Southeast of Brazil). A total of 192 haplotypes were identified, of which 184 were unique and 8 were found in 2 individuals. The average gene diversity of the 12 Y-STR was 0.6746 and the haplotype diversity was 0.9996. Pairwise analysis confirmed that our population is more similar with the Italy, North Portugal and Spain, being more distant of the Japan.  相似文献

Allelic frequencies for 12 short tandem repeats (STRs) (F13A01, F13B, FESFPS, LPL, CSF1PO, TPOX, TH01, vWA, D16S539, D7S820, D13S317 and D5S818) were estimated, also as forensic parameters, from a sample of 916 unrelated Brazilian subjects classified into four ethnic groups: European-derived, African-derived, Brazilian Mulattos and Asian-derived.  相似文献
