A COMPETITIVIDADE E O GRAU DE CONCENTRAÇÃO DAS EXPORTAÇÕES DO COMPLEXO SOJA DO BRASIL, DA ARGENTINA E DOS ESTADOS UNIDOS DA AMÉRICA NO PERÍODO 1995/2010
This paper analyzes the export competitiveness of soybean in Brazil, Argentina and the United States and the degree of concentration in the main export markets of these countries in the period 1995/2010, using both the index of Revealed Comparative Advantage (RCA) and Concentration ratio (CR). The results reveal, based on the CR3 , that Argentina and Brazil show an increase in the concentration ratio of even crushed soybeans and crude soybean oil, while the US in even crushed soybeans and fractionated soybean oil even. The RCA index shows advantages for all products/countries in both years, except the soy flour to Brazil and Argentina that had values below one. For the US the indexes were lower when compared to the other countries, although it remained as the main exporter of soy flour, fractionated soybean oil even and even crushed soybeans.
The Revealed Comparative Advantage Index of Brazilian Natural Honey
Natural honey is considered a valuable forestry product not only for biodiversity but also to its conservation functions. Besides, it is an important exported commodity. In this study, the performance of Brazilian natural honey exported products were evaluated with specific focus on determination of their competitiveness in the international market. This article aimed to calculate the Revealed Comparative Advantage Index (RCA) of Brazilian natural honey, from 2000 to 2015. The sources consulted are SEBRAE, IBGE, Brazilian Ministry of Development, Industry and Foreign Trade and the United Nations Commodity Trade Statistics Database (UN COMTRADE). The methodological procedure used was Balassa’s Revealed Comparative Advantage Index in order to estimate the competitiveness measure. The results demonstrated that Brazil was competitive in natural honey exported products during the period from 2002 to 2015. Considering the outcomes, based on the indexes it is possible to affirm that Brazilian natural honey is competitive and the country displays enough positive characteristics and productive capacity to amplify its participation in new international commercial markets.
Gill diseases of cultured salmonids in Ontario.
Between 1977 and 1981, the Fish Pathology Laboratory of the Ontario Veterinary College received 239 cases from trout farms of southern Ontario, 51 (21.3%) of which had diseased gills. Branchial lesions in 86.3% of these 51 cases were characterized by marked lamellar epithelial hyperplasia with epithelial hypertrophy and lamellar fusion. Filamentous bacteria were seen on the surface of the branchial filaments and lamellae in 68.6% of the cases. Our observations highlight the importance of gill diseases as a production problem of farmed salmonids in southern Ontario.
