Balance-of-payments-constrained growth in Brazil: 1951-2008

The aim of this study is to determine whether Brazil's economic growth has been constrained by the balance of payments in the long run. The question underpinning the analysis can be expressed as follows: Was economic growth in the period 1951-2008 constrained by the balance of payments? To answer this question, the study employs the externally constrained growth methodology developed by Lima and Carvalho (2009), among others. The main statistical method used is vector error correction. The conclusion is that the rate of economic growth in Brazil was restricted by the external sector in the period concerned, validating the theory of balance-of-payments growth constraint with regard to the economic history of Brazil.

Development and energy balance of sugarcane in the norte fluminense, Brazil

The growing concern for renewable and cleaner energy sources has increased the demand for biofuels, pointing out the ethanol from sugarcane. The aim of this study was quantify the partition of energy balance components and monitor the physiological development indexes of the sugarcane, relating them to water availability conditions of climate and soil in Campos dos Goytacazes, Norte Fluminense, Brazil. To this end, a micrometeorological station was settled in an area of 13 ha in commercial cultivation. The culture was regularly monitored at 85, 102, 128, 149, 174, 194, 215, 235, 255 and 280 days after cutting (DAC). The variations in water availability directly influenced the rates of crop growth and energy balance. Under the conditions studied most of the available energy (53%) was consumed by the latent heat flux.

Balance of pH of chicks from eggs injected with ascorbic acid and subjected to thermal stress

This study aimed to verify that chicks from eggs injected with ascorbic acid and subjected to heat stress would have changes in acid-base balance, compared to chicks incubated at thermoneutral without injection of ascorbic acid. The parameters evaluated were blood pressure of carbon dioxide and oxygen, base excess, total carbon dioxide, concentration of sodium, potassium, ionized calcium, bicarbonate and pH of newly hatched male chicks, hatched from eggs injected with acid ascorbic acid (AA) and subjected to heat stress during incubation. The experimental design was completely randomized in factorial scheme 5 (application levels of ascorbic acid) x 2 (incubation temperatures). The data were subjected to analysis of variance using the General Linear Model procedure (GLM) of SAS ®. For the blood pH was observed significant interaction (p <0.05) between treatments with application in eggs and incubation temperatures. For the other parameters were not significant effects (p< 0.05) of AA level and neither temperature of incubation. Analyzing the unfolding of the interaction to pH was observed that chicks from eggs injected with 6% ascorbic acid and subjected to heat stress during incubation had a higher pH value compared with the thermoneutral temperature incubated (p <0.05). Therefore, it is suggested that the incubation of eggs in high temperature (39°C) can alter the metabolic rate of these embryos.

The first Brazilian municipal initiative of payments for environmental services and its potential for soil conservation

It has become evident that policies aimed at mitigating the growing water resources and water use conflicts in Brazil are crucial. The municipality of Extrema in Minas Gerais state in Brazil pioneered the first Brazilian municipal PES initiative (Conservador das Aguas program), based on the relationship between forests and the benefits they provide. This study aimed to assess soil loss in the Posses sub-basin, where the Conservador das Aguas program began. Additionally, we aimed to determine the potential that this PES initiative has for soil conservation, as well as to minimize the soil losses as a function of forest area size and location in order to propose a technical approach for implementing PES. In this sense, considering the prescribed conservation practices, land use situation, and soil cover in the Posses sub-basin, we analyzed the effectiveness of the Conservador das Aguas program before and after implementation in relation to reduced soil loss under 36 different land use and soil cover scenarios. We used a geographic information system (GIS) for spatializing and producing different information plans and the Revised Universal Soil Loss Equation (RUSLE) for estimating soil loss. As a result, we found that minimization of soil loss may be obtained by adopting pasture conservation practices. Additionally the expected average soil loss in the Posses sub-basin under conditions of land use and soil cover, before and after implementing the water conservation program was 30.63 and 7.06 Mg ha(-1) year(-1), respectively.

Plano real e a nova realidade brasileira

This paper analyzes the Real Plan and its effects on two administrations of President Fernando Henrique Cardoso (FHC), a period which extends from 1995 to 2002. To this end, the study includes a brief review of the problems faced by previous plans, especially the Cruzado Plan and the reasons for the belief that it has been successfull in relation to inflation control. Additionally, seeking to describe the process of moving to the new currency towards stabilization, the paper describes the theoretical foundations of the Plan. In sequence, it defines the backround of both international and domestic monetary reform which was one important part of the Plan and therefore the reasons for the implementation of the monetary reform. Subsequently the paper deals with the effects of the Plan on the economy as a whole, covering also the way the economic measures were taken concerning the Mexican and Asian crisis, the policies used fot the exchange rate, interest rate, fiscal accounts, balance of payments, among other factors and the relationship between them. Hence, it describes the immediate and the long-term consequences of stabilization program in terms of output, employment, public deficit and debt. Therefore, it is important to note the various junctures to which the economy was exposed, and also to point out the challenges and obstacles arising from these changes for growth, which was sometimes fast, sometimes slowing down - the so-called stop and go. Of course, facts as the moving to floating exchange rate regime, the adoption of inflation targeting regime and the adoption of fiscal responsibility law along with the primary surplus policy were able to create a new economic environment and to contribute to later success of the Cardoso years

O FMI e o Sistema Financeiro Internacional: uma análise das mudanças estratégicas nas décadas de 1980 e 1990

The current study has aimed to analyze changes in strategies at the International Monetary Fund that occurred during the 1980s and 1990s. The analysis is done through the the recovery of the 1980s international economic scene, amid the global recession and debt crisis, and shows how the course of the decade and influenced changes under recommendations provided by the IMF to countries with balance of payments crisis. Furthermore, the paper also describes the changes in the international financial system, in some countries which have adopted them and also to the International Monetary Fund itself

Restrição externa e taxa de câmbio no Brasil: 1980-2008

The objective of this study is to examine if economic growth in Brazil was blocking due to external constraints, that is, in consequence of its Balance of Payments. We work with the approach first proposed by Thirlwall (1979) which was later modified by Lima and Carvalho (2009). We can conclude that economic growth was restricted by the external sector, which is consistent with the economic history of Brazil, and verify that the real exchange rate, and to influence the trade balance in the course run, also excerce some influence on this account balance of payments in the long run.

A controlled clinical trial on the effects of motor intervention on balance and cognition in institutionalized elderly patients with dementia

Purpose: To analyse the effects of two interventions on the cognition and balance of institutionalized elderly people with mixed dementia.Methods: Fifty-four participants were allocated into three groups. Group 1 was assisted by an interdisciplinary programme comprising physiotherapy, occupational therapy and physical education. A physiotherapist alone carried out the intervention in group 2. Group 3 was considered as control. Assessors were blinded to guarantee the absence of bias. Cognitive functions were analysed with the Mini-Mental State Examination and the Brief Cognitive Screening Battery. Balance was assessed with the Berg Balance Scale and the Timed Get-Up-and-Go Test. Multiple analysis of variance (MANOVA) was used to test possible main effects of the interventions.Results: The results showed benefits on the balance of subjects in both groups 1 (F=3.9, P < 0.05) and 2 (F= 3.1, P < 0.05), compared with group 3. MANOVA did not indicate benefits on the cognitive functions between groups 1 and 3 (F= 1.1, P > 0.05) and groups 2 and 3 (F= 1.6, P > 0.05). However, univariate analysis indicated some benefits of the interdisciplinary intervention on two specific domains measured by the Brief Cognitive Screening Battery (F=26.5, P < 0.05; F= 4.4, P < 0.05).Conclusion: Six months of multidisciplinary or physiotherapeutic intervention were able to improve a person's balance. Although global cognition did not improve through treatment, when the intervention was carried out on a multidisciplinary basis we observed an attenuation in the decline of global cognition on two specific cognitive domains. Exercises applied in different contexts may have positive outcomes for people with dementia.

Potential of municipal solid waste (MSW) as a source of energy in São Paulo: Its impact on CO2 balance

Energy generation is needed in São Paulo and MSW represents a promising alternative, although it is more expensive than hydroelectric power. About 14 900 t/day of MSW is generated, of which 8433 t/day is domestic and commercial MSW. From this amount, 1800 t will be destined to generate 30 MW of power. The eco-balance of CO2 has been considered for incineration and recycling. The recycling program of plastics, metals, paper and glass would represent a significant reduction in energy and CO2 emission. The total CO2 released is 3.34 x 10(5) t/yr without recycling. and is 1.25 x 10(5) t/yr with a recycling program. Most of the CO2 comes from plastics and paper production. Economic aspects could probably favor Incineration with energy production as the best option. (C) 1998 Published by Elsevier B.V. Ltd. All rights reserved.
