Athematic participles in Brazilian Portuguese: A syncretism in the making
Some Portuguese verbs have two different past participles, such as, e.g.,
aceitar
‘accept’, with participles
aceitado
and
aceito
; and
limpar
‘clean’, with
limpado
and
limpo
. The first one in each pair mentioned is thematic, whereas the second one is athematic. While regular thematic participles all bear stress on the theme vowel, these athematic participles all bear the primary stress on the athematic stem. As the morphosyntactic category first person singular present indicative (1spi) is realized by {-o}, it normally coincides the masculine form of this athematic participle, giving rise to a syncretism between 1spi and the participle. The aim of this paper is to track the appearance of this kind of participle and the resulting syncretism in Portuguese and the changes making it possible for new participles to be formed in this way in colloquial Brazilian Portuguese

Growth Complementarity Between Agriculture and Industry: Evidence from a Panel of Developing Countries
Abstract: Using dynamic panel models with data for 62 developing countries, this paper examines whether growth in agriculture elicits growth in manufacturing. For identification, I use population-weighted, average temperature as an instrument for growth in agriculture. I identify large short-run effects: An increase in growth in agriculture by one percentage point is estimated to raise contemporaneous growth in manufacturing by between 0.47 and 0.56 percentage points. The baseline models also imply sizable long-run effects of permanent increases in growth in agriculture. Extensions of the empirical model suggest that growth in agriculture benefits the manufacturing sector by improving its domestic terms of trade, by increasing the share of investment and saving in GDP, and by increasing the capacity to import industrial inputs. The paper makes two main contributions. First, it joins a growing literature using climate data to identify supply shocks in agriculture, establishing a robust empirical relation between these shocks and growth in manufacturing. Second, it includes a stylized two-sector model to illuminate the macroeconomic channels behind this complementarity. Together, these contributions lend support to the notion that agriculture plays key macroeconomic roles in the industrialization of developing countries by relieving saving, aggregate demand, _scale, and foreign exchange constraints on the industrial sector
ARTIFICIAL INTELLIGENCE AND COPYRIGHT
A Inteligência Artificial é uma das tecnologias emergentes com mais potencial nos dias atuais. A escala de utilização é cada vez mais abrangente e há muitas Empresas envolvidas no desenvolvimento desta tecnologia, com investimentos avultados. Neste sentido, questões relativas a quem detém a propriedade intelectual têm sido levantadas em diversos sistemas jurÃdicos, com diferentes abordagens. Saber quem é possuidor do direito de autor das obras produzidas por uma IA é importante, uma vez que terá um impacto direto no desenvolvimento desta tecnologia. Na verdade, é primordial quando se trata de IA totalmente autónomas, uma vez que não há nestas a intervenção humana. Outro caminho seria a criação de uma personalidade jurÃdica robótica, o que levanta questões éticas e legais que aparentemente demorarão a ser superadas.

Essays on Growth Complementarity Between Agriculture and Industry in Developing Countries
This dissertation examines three aspects of the macroeconomic role of agriculture in the industrialization of developing countries. In the first essay, I utilize instrumental variable techniques to empirically identify the effect of growth in agriculture on growth in manufacturing. Using data for 62 countries and instrumental variable techniques, I find that higher land yields in agriculture raise growth in manufacturing in the short to medium run. Along with extensions of the basic empirical model, this finding suggests that land-saving technical change can stimulate demand for industrial goods, raise fiscal revenues, and provide foreign exchange earnings to finance capital accumulation. In the second essay, I examine the role of biased-technical change in agriculture in the formation of aggregate demand for industry. I use a two-sector growth model to show that, under conditions of low factor substitutability and hidden unemployment, land-saving innovations can raise rural employment, enlarge the domestic market for manufactures, and promote faster industrial accumulation --- in contrast to labor-saving innovations. I also develop saving-constrained and open economy extensions of the baseline model. The essay casts light on a recent strand of empirical studies --- including the first essay of this dissertation --- which have identified a positive impact of higher land yields on industrial growth. Finally, in the third essay I develop a political-economic explanation for the labor-displacing trend that existed across the larger and most dynamic agricultural establishments in Brazil during the 1950-1980 period. Using primary data and the secondary literature, I document this trend and argue that it resulted from the interaction between public policies to promote the use of modern inputs, on the one hand, and size and power inequality across landholdings, on the other hand. As a result, the pattern of technical change in agriculture aggravated the problem of underemployment that beset Brazil\u27s industrialization, preventing a broader distribution of its benefits
Cultura dos cuidados: o debate entre história e enfermagem pré-profissinal nas aquarelas de Jean-Baptiste Debret (1816-1831)
Ao identificar práticas de cuidar e curar realizadas por homens e mulheres negros, o estudo evoca o contexto histórico marcado pela transferência da Coroa Portuguesa (1808-1820) para o Brasil, espaço social significado como propÃcio para o desenvolvimento de doenças. Os registros pictóricos legados da obra de Jean-Baptiste Debret, preservados nos Museus Castro Maya, Rio de Janeiro, foram usados como fonte e os resultados apresentam lugares sociais do cuidado e seus executores, bem como os nexos entre História e História da Enfermagem Pré-profissional brasileira em suas relações oblÃquas com a cultura dos cuidados.La identificación de las prácticas de cuidar y curar realizadas por hombres y mujeres negros, permitio el estudio del contexto histórico marcado por la transferencia de la Corona Portuguesa (1808-1820) para Brasil, espacio social significado como propicio para el desarrollo de enfermedades. El registros pictóricos legados de la obra de Jean-Baptiste Debret, conservados en el Museo Castro Maya, Rio de Janeiro, fueron utilizados como fuentes de la investigación y los resultados apresentan lugares sociales de atención a la salud y sus executores, asà como los vÃnculos entre Historia e Historia de la EnfermerÃa Pre-Profesional brasileña en sus relaciones oblicuas con la cultura del cuidados.To identify practices to care for and cure performed by black men and women, the study evokes the historical context marked by the transfer of the Portuguese Crown (1808-1820) to Brazil, social space meant as conducive to the development of diseases. Legacy pictorial records of the work of Jean-Baptiste Debret, preserved in the Museum Castro Maya, Rio de Janeiro, were used as the source and the results are social places of care and its performers as well as the links between History and History of Pre-Professional Brazilian Nursing in their oblique relations with the culture of care
Manejo de Thrips tabaci em cebola orgânica com terra de diatomáceas.
O objetivo deste trabalho foi avaliar o efeito da terra de diatomáceas sobre a incidência de tripes e a produtividade e o peso médio de bulbos em cebola no sistema orgânico. O trabalho foi conduzido entre agosto e dezembro de 2004 e de 2006. Em 2004, os tratamentos constaram de pulverização de terra de diatomáceas a 1% , 2% e 3% , e testemunha sem aplicação. Em 2006 usou-se terra de diatomáceas pulverizada a 0,5% e 1% , e em aplicação no sulco de plantio, nas dos e s de 40 k g/h a aos 30 dias após transplante (DAT) e 45 DAT;60 k g/h a aos 30 e 45 DAT;20 k g/h a aos 30 e 45 DAT;30 k g/h a aos 30 e 45 DAT, e testemunha sem aplicação. O delineamento foi de blocos ao acas o com quatro repetições. A terra de diatomáceas não reduziu a população do inseto, nem alterou a produtividade e o peso médio de bulbos . A corre lação do inseto e o rendimento não foram significativamente negativos , o que sugere ser possÃvel produzir cebola orgânica sem o uso de inseticidas naturais para o manejo de tripes
