Educational Thresholds and Economic Growth: Empirical Evidence from Brazilian States

This paper examines the convergence process in Brazil over the period of 1985-2004, giving a special attention to the role of human capital as a conditioning factor to convergence. It examines how different levels of human capital influence growth in different regions of Brazil. Different measures of human capital are used in the growth regressions and the results show that they play a significant role in explaining the growth process. The evidence indicates that different levels of human capital have different impacts on the per capita income growth, depending on the level of development of the states. Lower levels of human capital explain better the convergence among the less developed states and higher levels of human capital are more adequate among the more developed states. The impact of the relative intermediate levels of human capital on growth is stronger in all samples, suggesting the existence of threshold effect in education.conditional convergence, human capital thresholds, panel data

SMEs and Regional Economic Growth in Brazil

This paper examines the relationship between the Small and Medium Enterprise (SME) sector and economic growth for an annual panel of Brazilian states for the period 1985-2004. We investigate the importance of the relative size of the SME sector measured by the share of the SME employment in total formal employment and the level of human capital in SMEs measured by the average years of schooling of SME employees. The empirical results indicate that the relative importance of SMEs is negatively correlated with economic growth, a result that is consistent with previous studies examining developing countries. In addition, our results also show that human capital embodied in SMEs may be more important for economic growth than the relative size of the SME sector.Firm size, market structure, economic growth, human capital.

Restelo in Lisbon - The Non-implementation of the Original Urban Design by Faria da Costa during the Dictatorship of António de Oliveira Salazar

Beiträge zum Symposium „Urban design and dictatorship in the 20th century: Italy, Portugal, the Soviet Union, Spain and Germany. History and Historiography“. Weimar, 21.-22. November 2013For decades in Germany, historical research on dictatorial urban design in the first half of the 20th century focused on the National Socialist period. Studies on the urban design practices of other dictatorships remained an exception. This has changed. Meanwhile, the urban production practices of the Mussolini, Stalin, Salazar, Hitler and Franco dictatorships have become the subject of comprehensive research projects. Recently, a research group that studies dictatorial urban design in 20th century Europe has emerged at the Bauhaus-Institut für Geschichte und Theorie der Architektur und der Planung. The group is already able to refer to various research results. Part of the research group’s self-conception is the assumption that the urban design practices of the named dictatorships can only be properly understood from a European perspective. The dictatorships influenced one another substantially. Furthermore, the specificities of the practices of each dictatorship can only be discerned if one can compare them to those of the other dictatorships. This approach requires strict adherence to the research methods of planning history and urban design theory. Meanwhile, these methods must be opened to include those of general historical studies. With this symposium, the research group aims to further qualify this European perspective. The aim is to pursue an inventory of the various national historiographies on the topic of “urban design and dictatorship”. This inventory should offer an overview on the general national level of historical research on urban design as well as on the level of particular urban design projects, persons or topics. The symposium took place in Weimar, November 21-22, 2013. It was organized by Harald Bodenschatz, Piero Sassi and Max Welch Guerra and funded by the DAAD (German Academic Exchange Service)

SMEs, regional economic growth and cycles in Brazil

This thesis presents an examination of the importance of Small and Medium Enterprises (SMEs) for economic growth and examines how sensitive employment in SMEs is to business cycle fluctuations in Brazil. The thesis uses different empirical techniques to investigate the role of SMEs in the Brazilian regional economic growth, using a panel dataset from 1980 to 2004 for 508 Brazilian micro-regions. It first uses standard panel data estimators (OLS, LSDV, system and first differenced GMM) to analyse the (augmented) Solow growth model encompassing the importance of the relative size of the SME sector measured by the share of the SME employment in total formal employment and the level of human capital in SMEs measured by the average years of schooling of SME employees. The results show that the size of the SME sector is not significantly important for regional economic growth, but that human capital embodied in SMEs is more important in this process. [Continues.

Fixed drug eruption to cetirizine with positive lesional patch tests to the three piperazine derivatives

BACKGROUND: The H1-antihistamine cetirizine, a piperazine derivative widely used in daily practice, is rarely the cause of cutaneous drug reaction. Nevertheless, four cases of fixed drug eruption (FDE) as a result of this drug have been described recently. We present the case of a 45-year-old woman with a multilocalized FDE following oral intake of cetirizine for allergic rhinitis. METHODS: Patch testing with hydroxyzine 1% and 10% in petrolatum (Chemotechnique), and with powdered Zyrtec (cetirizine) and Xyzal (levocetirizine) pills, prepared at 20% in water and at 20% in petrolatum, was performed in both residual lesions and healthy skin. RESULTS: Positive results (++) to these drugs (24 h occlusion and readings at days 2 and 3) were obtained in residual lesions only. These results allowed us to confirm the drug responsible for this FDE and to study cross-reactions between antihistamines of the same chemical family. CONCLUSIONS: To the best of our knowledge, this is the first report of FDE to cetirizine with positive patch testing to hydroxyzine, cetirizine, and levocetirizine. This case highlights the importance of patch testing in the study of cutaneous drug reactions, namely FDE

Variability of nutrients and chlorophyll a in Ancao Inlet during a spring tidal cycle in April 2009

Sao Luis or Ancao Inlet is the most western of the six inlets of the Ria Formosa lagoon, in southern Portugal. This inlet contributes relatively little to the water volume exchange over a tidal cycle (similar to 10%). Temperature, salinity, pH, dissolved oxygen, and chlorophyll a and nutrient concentrations were measured hourly at the surface, at an intermediate level, and near the bottom over a complete spring tidal cycle, at a sampling point in the middle of the inlet. Current velocity was also measured hourly over the entire cross-section of the inlet using an acoustic Doppler current meter. From these parameters, the flow rate and the transport of nutrients and chlorophyll a were calculated and integrated over the complete tidal cycle providing the net transport. The results show that this is a well-mixed dynamic inlet where, during spring tide, the tidal signal is evident particularly for the nutrient and chlorophyll a concentrations. The nutrient concentrations were low (almost depleted), while the chlorophyll a concentrations were high (4-6 mg m(-3)). The estimated transports through Ancao Inlet revealed that there was a net import of chlorophyll a, nitrate, and phosphate to the Ria Formosa lagoon, while silicate was exported to the adjacent coastal area.Center for Marine and Environmental Research (CIMA, Portugal)info:eu-repo/semantics/publishedVersio

Constrangimentos da tarefa e padrão de bipedia em bebé com hipotonia: estudo de caso

Fatores biológicos e ambientais podem influenciar o desenvolvimento motor. O desenvolvimento motor é, assim, um processo plástico, e a variação na sequência, no tempo e na velocidade de desenvolvimento está provavelmente relacionado com uma variedade de fatores biológicos (e.g., genótipo) e do ambiente (e.g., tipo de estimulação). O desenvolvimento motor deve ser visto numa perspetiva dinâmica, decorrente de interações da criança incorporada no seu meio ambiente (Malina & Bouchard, 1991). Desta forma, a capacidade de controlo postural (constrangimentos individuais), a força gravítica que nela atua (constrangimento do envolvimento) e as propriedades do contexto com que interage (constrangimento da tarefa) são fatores que determinam o padrão de comportamento motor da criança (Nazário, 2011).info:eu-repo/semantics/publishedVersio
