Análise de redes mostra crescimento do debate sobre transparência

O tema da transparência ganhou forte repercussão no noticiário e no debate público na última semana durante a troca de comando do Ministério da Transparência, Fiscalização e Controle, órgão responsável pelo combate à corrupção e pela promoção do controle social e do acesso à informação. Um levantamento realizado pela FGV/DAPP mostra que entre os dias 25 e 31 de maio houve um reforço do debate nas redes sociais sobre o tema, especialmente após a renúncia do então ministro Fabiano Silveira, o que pode indicar que a transparência vem se consolidando na pauta por uma governança mais ética e participativa.

ANÁLISE DA INFORMALIDADE: uso de crédito e crescimento perante a pesquisa da Ecinf

Este trabalho procura entender um pouco mais e discutir, partindo dos dados disponíveis do Instituto Brasileiro de Geografia e Estatística (IBGE), através de sua pesquisa de economia informal urbana (ECINF) gerada em 2003 (ultima disponível), aspectos ligados à informalidade, crescimento e uso do crédito. Procura explorar, neste contexto, aspectos relevantes ao crescimento e continuidade da micro e pequena empresa. Para atingir este objetivo, procura-se entender inicialmente conceitos sobre estes aspectos (informalidade, crescimento e uso de crédito) e suas características, e através de dados secundários e com o uso de software estatístico, procurar entender as suas relações, através de ANOVA e regressões, bem como optimal scaling contribuindo para o conhecimento deste cenário. Os dados levantandos e comparados com a teoria apontam as relações entre empregador e trabalhador por conta própria indicando dos fatores adotados no estudo quais mais contribuem e os que indicam pouca contribuição dentro deste contexto. Em conclusões acena para uma tendência onde o individamento através do uso de crédito tende a gerar um maior crescimento até um determinado ponto e a partir desta inflecção tende a dificultar a atividade bem como acena dificultar a formalização.(AU)

Termos de troca, preço das commodities e o crescimento brasileiro : uma análise sob o prisma da restrição externa

This study aims to investigate the relationship between terms of trade and the long-term growth of Brazilian economy, from the perspective of external constraint, between the period 1994 to 2014. For this purpose, it is based on Thirlwall's (1979) original contribution, in order to empirically test the terms of trade contribution for determining the Brazilian growth potential product equivalent with Balance of Payments equilibriun. Using cointegration method, which seeks to analyze the long-term relationship between the variables, and subdividing the period into two sub-periods, 1994-2004 and 2004-2014, we estimate and compare real and hypothetical income elasticities and predicted and observed growth rates, with and without the terms of trade, for each period. The obteined results show that the inclusion of terms of trade in the empirical procedure to test the validity of Thirlwall's Law lead to higher growth rates obtained by the model (hypothetical), for the entire period 1994-2014 and for the sub-period 2004 -2014. This "theoretical" relaxation of the external constraint, caused by the inclusion of the terms of trade in traditional Thirlwall's rule, overestimated the average real growth rate for these periods, while the traditional Thirlwall's Law - without terms of trade - has adapted better to the real behavior of Brazilian economy. Thus, despite having contributed potentially for the relaxation of external constraint on Brazilian growth, the effect of terms of trade may have been offset by the negative performance of other Balance of Payments components, as capital flows and interest, profits and dividends payments abroad.

Perfil exportador e crescimento econômico: uma análise de painel para economias africanas

This study aims to evaluate the relationship between the export profile and the African GDP growth rate. Chapter 1 presents the literature on the subject and studies that analyze the specific case of Africa. There seems to be a consensus that exports contribute to economic growth. However, there is no consensus on the benefits that are incorporated from exported products. The divergence lies between the approach of the Natural Resources Curse, where concentration of exports in commodities does not contribute to economic growth. Another work line supports the idea there is no such relation. Chapter 2 presents, through descriptive analysis, macroeconomic and international trade data for African economies data. Based on data from 52 countries for the period 1990-2014, it can be observed that the African continent has improved in macroeconomic terms, with increased exports and economic growth rates, suggesting a positive relationship between the variables. Trade indicators show Africa's integration into the global economy, with European Union, USA, China and some emerging countries as main partners. In addition, the analysis showed that the export is concentrated in oil and agricultural commodities. Most African countries face a negative trade balance, depending of primary products exports with low added value and imports of manufactured goods. Finally, Chapter 3 presents an empirical research using panel data analysis. The results suggest, in general, evidences that exports are important for explaining the African economic growth rate of African economies can be stimulated by the expansion of the share of exports in GDP. The estimated coefficients are positive and statistically significant in both the fixed effect estimation, as the estimation by GMM System. The estimation of growth models for fixed or random effects indicates a direct and statistically significant relationship between export oil / minerals and the growth rate of African countries. Thus, the export profile turns out to be important to determine the growth rate. The results obtained from the estimates do not corroborate the literature arguments called Curse of Natural Resources for the period analyzed, since export natural resources, especially oil and minerals, were relevant to explain the performance of the growth rate of economies.

Padrão de especialização comercial e crescimento econômico : uma análise sobre o Brasil no contexto da fragmentação da produção e das cadeias globais de valor

Globalization and technological changes that has happened since the 80s have brought remarkable changes in the industrial and commercial paradigm, which are expressed mainly in the international fragmentation of production and in the formation of Global Value Chains (GVC). This thesis sought to understand such phenomena and discuss new relevant variables in this context for a more accurate analysis of the current trade patterns not addressed by the seminal economic theories that relate trade and economic growth. It sought to evaluate how the trade specialization pattern of Brazil evolved compared to other economies (China, India, Russia, United States, Japan and selected Latin American economies) in the light of these phenomena from 1995 to 2011. Therefore, we have used the methodology of gross exports decomposition in value added measures, developed by Koopman et al. (2014), and indicators estimated from data of two global matrices I-O: a WIOT (2013) and the TiVA (2015). It was also tested two hypotheses regarding the role of these phenomena as determinants of economic growth in recent years: 1º) fragmentation and participation in GVC ensure higher growth rates for countries; 2º) the place (stage) in which the country finds itself in GVC associated with sectoral technological aspects is also important for economic growth. For this, we used dynamic panel models (Difference GMM and System GMM) for a sample of 40 countries from 2003 to 2011. The studies carried out on Brazil show that the country is no longer on the margins of these phenomena, because it shows increasing rates of participation in GVC, including in sectors considered most strategic for fragmentation. However, there is not a standard convergence of trade specialization of the country to those presented by developed countries or movements earned by China and Mexico in terms of their position and profile of participating in GVC. Another important result obtained by the thesis is the identification of these phenomena are in fact new variables relevant for economic growth, because it shows empirical evidences to support the hypothesis 1 and, partially, the hypothesis 2. A joint analysis of the estimated econometric results with the results of the descriptive analysis of the Brazilian economy, it leads us to conclude that the trade specialization pattern of the country in the context of the new trade setups is presented unfavorably to its growth strategy.

Análise do comportamento e crescimento do camarão branco Litopenaeus vannamei (Boone, 1931) em diferentes substratos inconsolidados

The aim of this study was to test the sediment preference of L. vannamei shrimp. It was observed shrimp visit frequency, swimming and burying behaviour at different sediment compositions for 24h. Juvenile (0.93 ± 0.29g) and sub-adult shrimps (10.0 ± 1.18g) were obtained from the aquaculture station at Universidade Federal Rural do Semi-Árido UFERSA, and held in a plastic tank (water volume 500 L) supplied with aerated water and kept at constant temperature, pH, and salinity. Shrimp was fed by commercial shrimp dry food. The experimental substrates were composed by A: medium sand + thick sand + very thick sand + gravel; B: very fine sand + fine sand; and C: silt + clay. Thus, six different substrate combinations were tested: A, B, C, A+B, A+C, B+C. To test preference, it was used a cylindrical tank (40 l) divided into six differently substrate compartments. A single shrimp was introduced each tank and the frequency at which this shrimp visited each compartment was recorded over a 24h study period. It was tested 54 shrimp (18 sub-adult males, 18 subadult females and 18 juveniles). For each trial, sediment and water were changed to avoid pheromones and residues influence. Shrimp were weighted and sub-adults were divided by sex: males present petasma and females present thelycum. Data were collected on the experimental day at 19:30; 20:30; 00:30; 1:30; 05:30; 06:30; 13:30 and 14:30 h. At each time point, shrimp were observed for 20-min periods, in which we noted down which compartment the shrimp was occupying at 2-min intervals. Thus, for each period we had eleven observations (88 observations per day). For observations at night, it was used dim red light that did not affect shrimp behaviour. At each 20-min period, it was observed visit frequency in each substrate, if shrimp was burred or not or if it was swimming. There was not significant difference between light and dark burry activity for females. Swimming activity was significantly higher at night, mainly at 00:30 and 01:30 h. All L. vannamei shrimp showed preference for sediment B. This animal presents cyclic activity, spends the day light period buried and swims at night

Análise dos impactos do PAC sobre o crescimento do PIB a preços correntes

O Programa de Aceleração do Crescimento (PAC) abrange uma série de medidas de caráter econômico, e teve como finalidade promover a retomada dos investimentos em setores estratégicos da economia. Este trabalho teve como objetivo principal comparar um período sem o programa (1994-2006) com o período em que foi implantado o PAC (2007-2013). Assim, pode-se verificar que o crescimento da economia brasileira, medido através do Produto Interno Bruto (PIB) a preços correntes, foi influenciado pelos investimentos ocorridos através do programa, mesmo que esse intervalo seja marcado por uma grande crise, em 2008. Pois, como apontam os resultados obtidos desse estudo, no intervalo 2007-2013 as taxas médias de crescimento do PIB, Formação Bruta de Capital Fixo (FBCF) e Utilização da Capacidade Instalada (UCI) são maiores do que as do intervalo 1994- 2006.

Modelo de programação quadrática para análise da movimentação logística e comercialização da soja brasileira

The purpose of this work was to analyze the logistical distribution of Brazilian soybean by applying a quadratic programming to a spatial equilibrium model. The soybean transportation system is an important part of the soybean complex in Brazil, since the major part of the costs of this commodity derives from the transportation costs. Therefore, the optimization of this part of the process is essential to a better competitiveness of the Brazilian soybean in the international market. The Brazilian soybean complex have been increasing its agricultural share in the total of the exportation value in the last ten years, but due to other countries' investments the Brazilian exportations cannot be only focused on increasing its production but it still have to be more efficient. This way, a model was reached which can project new frames by switching the transportation costs and conduce the policy makers to new investments in the sector.

Crescimento e composição corporal de uma coorte de crianças e adolescentes com diabetes tipo 1

OBJECTIVE: To evaluate the growth and body composition of children and adolescents with type 1 diabetes mellitus (T1DM). SUBJECTS AND METHODS: A cohort of 44 patients with T1DM were followed up for approximately four years and compared with a control group. Weight, height, body mass index (BMI), body fat percentage (BF%), fat mass index, waist circumference (WC) and waist-height ratio were determined. RESULTS: In females, in the first evaluation, BF% was lower in patients than in controls, while in the second evaluation, mean WC was higher in patients than in controls. In males, height of the patients was lower in the first evaluation, while body mass index (BMI) was higher in the second one. We did not find any differences among the changes in height, weight and BMI z-scores and BF% or in the distribution of those z-scores between the two evaluations, in both groups. Multiple regression analysis found differences in BMI and waist-height ratio in both sexes and also in WC in females. CONCLUSION: The patients had adequate growth but showed discrepancy in their body composition during the study.
