Arkhanka, mon berceau !
No full textThe author is using documents from a personal archive and tells a story based on anecdotes as well as edited memoirs of her mother Nadezhda Reformatskaya . She had the fortune to spend her youth in one of the last small Russian country homes. Lively accounts ofprovincial country life at the beginning ofthe twentieth century give way to dramatic scenes of the conscription to send troops to the frontline of the First World War. The title of the article paraphrases the lines from a poem by A. N. Nekrasov “ On the Volga” (1860).Reformatskaâ Mariâ Aleksandrovna, Groppo Armelle. Arkhanka, mon berceau !.

Le cas Schafranek : un historien devant la justice
No full textBruno Groppo, "The Schafranek Case" : An Historian before the Bar
Since 1991, the Austrian historian Hans Schafranek is the object of a legal action that concerns all historians of modern history. Author of a book about the deportation from the Soviet Union of hundreds of German and Austrian antifascists to Nazi Germany between 1937 and 1941, he has been brought to court and convicted of using archival documents open to any researcher, documents calling into question a political official who, previously, hotly denied that the deportations took place. Even the decision of the court of appeals, favorable to the defendant, in part of a dangerous precedent with respect to the freedom to do research and publish in the field of contemporary history. The scientific community in Germany and Austria has mobilized in defense of Schafranek and this freedom to do research.Groppo Bruno. Le cas Schafranek : un historien devant la justice.

EMPIRICAL ESSAYS IN DEVELOPMENT ECONOMICS
No full textIn developing countries, where formal credit and insurance markets are incomplete or non-existent, households use informal mechanisms to increase their consumption, savings and insurance possibilities. This dissertation studies two of these informal devices: participation in Rotating Savings and Credit Associations (roscas), and internal migration. I mainly follow an empirical approach, using the Indonesia Family Life Survey dataset (IFLS).
In particular, I analyze the effect of mothers’ participation in roscas on children secondary or tertiary school enrollment: taking into account the endogeneity of maternal participation in roscas, I find that maternal participation significantly increases the probability of children’s school enrollment. The results show a negative correlation between the unobservables determining rosca participation and the unobservables determining schooling. This can be interpreted as evidence that in households that are more vulnerable to shocks, mothers invest less in their children’s education, while increasing their participation in roscas, as an insurance and savings device.
The subsequent chapter analyzes the determinants of internal migration in Indonesia, distinguishing between ‘individual migration’ and ‘family migration’, where the first relates to movements which individuals undertake alone, while the latter indicates movements they undertake with their families. The estimates, performed on men and women samples separately, highlight that individual and family migration have very distinct determinants. For instance, an increase in household wealth (proxied by the value of land owned) does not influence the probability of individual migration, while significantly reducing the probability of family moves. The results also show that, among men, individuals whose households have intermediate levels of income are less likely to move alone, compared to those in the extreme of the households' income distribution. This is consistent with the predictions of the New Economics of Labour Migration.
The final chapter (joint with M. Mendola, Università degli Studi di Milano Bicocca) studies the impact of internal migration on the consumption growth of origin households. We are able to disentangle the impact of current and return migration, while taking into account the endogeneity of internal migration. We find that having current internal migrants does not exert a statistically significant impact on origin households’ consumption growth, while having return internal migrants significantly reduces per capita consumption growth at origin. The IFLS data suggest that the negative effect of return migration on consumption growth is likely to be explained by a lower income potential of returning migrants with respect to current migrants and non-migrants

Lectotypification and synonymy in Hortia (Rutaceae)
No full textDuring taxonomic revision of the genus Hortia Vandelli (Rutaceae), it was necessary to lectotypify the name H. megaphylla Taubert because of the destruction of the holotype at B (luring World War II. This name is also formally synonymized under H. longifolia Spruce ex Engler. The author attribution is changed for H. longifolia Spruce ex Engler, crediting Spruce rather than Bentham
Dynamics of the natural regeneration of a cerrado stricto sensu in the Northeast of the State of São Paulo
No full textA savana pode ser definida, em linhas gerais, como um ambiente com características intermediárias entre campo e floresta. Em virtude de sua grande distribuição geográfica, sendo encontrada em aproximadamente 30% das áreas com estações secas do planeta, existem cerca de 200 definições diferentes para o conceito de savana. O Cerrado brasileiro, classificado como um tipo de savana, acompanha a tendência de apresentar inúmeras definições de acordo com o autor ou região. Apesar disso, pode-se afirmar que o Cerrado é o segundo maior bioma brasileiro ocupando cerca de 21% do território nacional, distribuindo-se em grande extensão norte-sul, apresentando desde formações florestais até campos abertos. No presente estudo define-se cerrado stricto sensu como o ambiente com a presença de árvores de pequeno porte, retorcidas e com ramificações irregulares, geralmente com cascas com cortiça e folhas xeromórficas. O atual estado de conservação das savanas é crítico e, especificamente no estado de São Paulo, essa situação não é diferente, sendo que os remanescentes de cerrado estão sob grandes pressões antrópicas, principalmente a pressão das atividades agrícolas que convertem a paisagem natural por meio da modificação da cobertura vegetal, comprometendo a conservação das áreas naturais, extremamente fragmentadas e alteradas. Dado o atual estado de conservação do cerrado, é fundamental o conhecimento da situação de conservação dos remanescentes e como estão ocorrendo os processos de regeneração natural dessas áreas contribui neste processo, pois para fundamentar qualquer ação de conservação, manejo ou intervenção direta as informações sobre a biodiversidade vegetal são essenciais. Assim, o objetivo deste estudo foi estudar aspectos da dinâmica da regeneração natural da vegetação de um remanescente de cerrado stricto sensu localizado no município de Patrocínio Paulista - SP. Para isso, caracterizou-se a composição do estrato adulto do remanescente, o estrato juvenil, a chuva e banco de sementes, complementando essas informações com dados fenológicos de seis espécies arbóreas, todos estudos realizados em um fragmento de cerrado stricto sensu com 100 ha localizado na Fazenda Santa Cecília, Patrocínio Paulista SP. Os resultados obtidos indicam claramente uma diminuição da biodiversidade vegetal local, onde os estratos regenerativos representam uma amostra muito pequena do estrato adulto atual. Aumentando-se a escala temporal da análise, utilizando os resultados apresentados pelo único estudo fitossociológico realizado no mesmo fragmento no ano de 2004, essa tendência fica ainda mais evidente, reforçando os resultados encontrados no presente estudo. A composição florística do estrato regenerativo com uma diversidade muito aquém do esperado, não apresentando uma biodiversidade compatível com o esperado, indica o fracasso do processo de regeneração no fragmento analisado. O processo de diminuição da biodiversidade vegetal local, com a possível extinção de muitas espécies vegetais em médio e longo prazos, caracteriza o fragmento analisado como um escoadouro de biodiversidade. Esse processo representa um enorme risco para a biodiversidade local e regional, alterando características estruturais e relacionadas à dinâmica da área. Estudos mais detalhados precisam ser desenvolvidos com o intuito de se verificar como as ações (naturais ou antrópicas) estão afetando diferentes componentes naturais (polinizadores, dispersores, aspectos fisiológicos das espécies vegetais etc.) provocando tão rápida diminuição da biodiversidade local. A manutenção em longo prazo da cobertura vegetal de uma área depende, diretamente, da capacidade de conservação e desenvolvimento dos complexos processos relacionados à regeneração natural da comunidade e, se de alguma maneira, esses processos forem afetados, toda a dinâmica natural de uma área pode ser comprometida.The savanna can be broadly defined as an environment with intermediate characteristics between field and forest. Due to its great geographical distribution, being found in approximately 30% of the dry areas of the planet, there are about 200 different definitions for the savanna concept. The Brazilian Cerrado, classified as a type of savannah, accompanies the tendency to present numerous definitions according to the author or region. In spite of this, it can be affirmed that the Cerrado is the second largest Brazilian biome occupying about 21% of the national territory, being distributed in great north-south extension, presenting from forest formations to open fields. In the present study cerrado stricto sensu is defined as the environment with the presence of small trees, twisted and with irregular branches, usually with bark with cork and xeromorphic leaves. The current conservation status of the savannas is critical and, specifically in the state of São Paulo, this situation is not different, being that the remnants of cerrado are under great anthropic pressures, mainly the pressure of the agricultural activities that convert the natural landscape through the modification of the vegetal cover, compromising the conservation of the natural areas, extremely fragmented and altered. Given the current state of conservation of the cerrado, it is essential to know the conservation status of the remnants and to know how natural regeneration processes are taking place in these areas, since in order to substantiate any conservation action, management or direct intervention information on plant biodiversity are essential. Thus, the objective of this study was to study aspects of the dynamics of the natural regeneration of the vegetation of a remnant of cerrado stricto sensu located in the municipality of Patrocínio Paulista - SP. For this, the composition of the adult stratum of the remnant, the juvenile stratum, rainfall and seed bank were characterized, complementing this information with phenological data of six tree species, all studies carried out on a fragment of cerrado stricto sensu with 100 ha in Fazenda Santa Cecília, Patrocínio Paulista - SP. The results clearly indicate a decrease in local plant biodiversity, where the regenerative strata represent a very small sample of the current adult stratum. Increasing the time scale of the analysis, using the results presented by the only phytosociological study carried out in the same fragment in the year 2004, this trend is even more evident, reinforcing the results found in the present study. The floristic composition of the regenerative stratum with a diversity that is much lower than expected, does not present a biodiversity compatible with the expected, indicates the failure of the regeneration process in the analyzed fragment. The process of decreasing local plant biodiversity, with the possible extinction of many plant species in the medium and long term, characterizes the fragment analyzed as a drainage of biodiversity. This process poses a huge risk to local and regional biodiversity, altering structural characteristics and related to the dynamics of the area. More detailed studies have to be carried out in order to verify how natural or anthropogenic actions are affecting different natural components (pollinators, dispersers, physiological aspects of plant species, etc.), causing a rapid reduction of local biodiversity. The long-term maintenance of the vegetative cover of an area depends directly on the conservation and development capacity of the complex processes related to the natural regeneration of the community and, if in any way, these processes are affected, all the natural dynamics of an area can be compromised
Chemical composition of essential oils of leaves, flowers and fruits of Hortia oreadica
No full textAbstractHortia oreadica Groppo, Kallunki & Pirani, Rutaceae, known as “para-tudo”, “quina”, and “quina-do-campo”, is used in traditional medicine locally to treat stomach pain and fevers. The aims of this study were: analyze the chemical composition of essential oils from leaves, flowers and fruits of H. oreadica and verify the seasonal variation of the chemical components of essential oils from leaves. The essential oils were obtained by hydrodistillation using a Clevenger type apparatus and analyzed by GC/MS. The major components found in the samples of the essential oils were the amorpha-4,7(11)-diene (29.27% – flowers, 20.26% – fruits, 27.66–37.89% – leaves), bicyclogermacrene (23.28% – flowers, 20.64% – fruits, 14.71% to 31.37% – leaves). This work represents the first study of the chemical composition of essential oils from leaves, flowers and fruits and seasonal variation in the essential oils from leaves of H. oreadica
O herói na literatura juvenil de Moacyr Scliar
No full textNesta dissertação estuda-se a produção literária juvenil de Moacyr Scliar, tendo como enfoque os tipos de herói presentes nas narrativas. Usando como metodologia a pesquisa bibliográfica, verifica-se qual o perfil dos heróis e em que medida eles representam comportamentos exemplares para o leitor jovem. Num primeiro momento, expõem-se os conceitos referentes à juventude, à literatura e ao herói, a partir das reflexões de Luís Groppo, Edgar Morin, João Luís Ceccantini, Regina Zilberman, Jaime Padrino, Lutz Müller, Carol Pearson, Joseph Campbell. Logo após, apresentam-se aspectos biográficos do autor e elementos de seus livros juvenis. Como fechamento, tem-se a análise da trajetória dos heróis, à luz de seu processo de amadurecimento. A obra juvenil criada por Scliar configura-se como uma verdadeira viagem de descobrimento, na medida em que seus heróis, ao completarem suas jornadas, vencem seus dragões e descobrem a si mesmos. A literatura aparece, assim, como instrumento de humanização do herói jovem.This dissertation presents the theme of the literary youth of Moacyr Scliar, focusing on the kinds of hero in these narratives. Using the literature as a methodology, it appears like the heroes of Scliar contribute to the formation of the young reader. At first, it exposes the theoretical concepts that include youth, literature and the hero. Soon after, we describe the biographical aspects of the author and the story of his youth books. As a closingm there us te analysis of the trajetory of the heroes and how is the process of humanization. The theory behind this study includes authors such as Luís Groppo, Edgar Morin, João Luís Ceccantini, Regina Zilberman, Jaime Padrino, Lutz Müller, Carol Pearson, Joseph Campbell. The juvenile literature created by Scliar is configured as a true voyage of discovery to the extent that their heroes, complete their journeys, their mature dragons and discover themselves. The literature, therefore, appears as a means of humanizing the young hero
