Vistas fotográficas das ferrovias: a produção de registros de obra pública no Brasil do século XIX / Photographic views of railroads: recording public works in nineteenth-century Brazil

Resumo O artigo analisa como a engenharia ferroviária articulou-se com a produção de fotografias no Brasil em meados do século XIX. A hipótese é a de que as exigências crescentes na execução de obras e o novo conhecimento cartográfico demandaram mais registros visuais, o que foi suprido e potencializado com o surgimento das técnicas fotográficas. Levantaram-se informações sobre registros fotográficos das estradas de ferro produzidos no Brasil após a década de 1850, a fim de analisar as características dessas imagens. A análise foi aprofundada numa série de fotografias de Marc Ferrez, por ter o maior volume de vistas ferroviárias atualmente acessível, o que possibilitou o reconhecimento de padrões nessas imagens a ponto de identificá-las como "registro fotográfico de obra".

Abstract This article analyzes how railway engineering was connected to the production of photographs in mid-nineteenth-century Brazil. The hypothesis is that growing demands related to the execution of projects and new cartographic knowledge required more visual records, which was supplied and leveraged with the emergence of photographic techniques. Data was collected on photographic records of railroads taken in Brazil after the 1850s to analyze the characteristics of these images. This analysis was further extended in a series of photographs by Marc Ferrez, since this collection contains the most views of railways currently accessible, permitting the recognition of patterns in these images to identify them as "photographic project records."

Fauna de besouros bioluminescentes (Coleoptera: Elateroidea: Lampyridae; Phengodidae, Elateridae) nos municípios de Campinas, Sorocaba-Votorantim e Rio Claro-Limeira (SP, Brasil): biodiversidade e influência da urbanização / Bioluminescent beetles (Coleoptera: Elateroidea: Lampyridae, Phengodidae, Elateridae) in the municipalities of Campinas, Sorocaba-Votorantim and Rio Claro-Limeira (SP, Brazil): biodiversity and influence of urban sprawl

O Brasil abriga a maior biodiversidade de besouros bioluminescentes do mundo. Apesar disto, levantamentos faunísticos regionais e estudos sobre o efeito da urbanização na biodiversidade de vaga-lumes são inexistentes. Este tipo de estudo pode ser especialmente importante para selecionar novos bioindicadores de ambientes noturnos. A biodiversidade de espécies bioluminescentes de Elateroidea em três grandes áreas urbanas no Estado de São Paulo: os municípios de Campinas, Sorocaba-Votorantim e Rio Claro-Limeira foi catalogada. Em Campinas, a ocorrência de espécies tem sido monitorada durante os últimos 20 anos. Foi registrada a ocorrência de 26 espécies em Campinas, 21 em Sorocaba e 19 em Rio Claro, sendo estas encontradas principalmente em áreas de Mata Atlântica, crescimentos secundários, brejos e campos. Apesar de vaga-lumes lampirídeos serem encontrados em todos os habitats, elaterídeos e fengodídeos ocorreram encontrados preferencialmente em áreas florestadas. A expansão urbana, em especial a iluminação artificial tem impacto evidente na biodiversidade deste grupo de insetos. Os lampirídeos Aspisoma lineatum Gyllendal, 1817 (Lampyrinae: Cratomorphini) e Bicellonychia lividipennis Motschulsky, 1854 (Photurinae) são as espécies mais frequentes em areas urbanizadas, ao passo que várias outras espécies de lampirídeos, elaterídeos e fengodídeos são as mais incomuns nestas áreas. Estes estudos oferecem subsídios para o uso deste grupo de vaga-lumes como potenciais bioindicadores noturnos.

Brazil hosts the richest biodiversity of bioluminescent beetles in the world. However, no surveys on the regional biodiversity have been made. Furthermore, studies on the effect of urbanization on bioluminescent beetle's biodiversity are still missing. Such kind of studies could be especially helpful to select new night environment bioindicators. Bioluminescent species of the Elateroidea superfamily occurring in three large and expanding urban areas in São Paulo State: Campinas, Sorocaba-Votorantim and Rio Claro-Limeira municipalities, were catalogued. In Campinas, the occurrence of bioluminescent beetles in different sites has been monitored during the past 20 years. There were 26 species in Campinas, 21 in Sorocaba-Votorantim and 19 in Rio Claro-Limeira, occurring mainly in conserved remnants of Atlantic Rain-forest, secondary growths, marshes and open fields. Whereas fireflies (Lampyridae) are found in almost all habitats, click beetles (Elateridae) and railroadworms (Phengodidae) occur predominantly in woody environments. Urban sprawl has an evident impact on the biodiversity of this selected group of beetles, and special attention should be given to the effect of artificial night lighting in the occurrence of these beetles. The lampyrids Aspisoma lineatum Gyllenhal, 1817 (Lampyrinae: Cratomorphini) and Bicellonychia lividipennis Motschulsky 1854 (Photurinae) are the most common species in urbanized areas, whereas many other species of lampyrids, elaterids and phengodids are rarely found in such environments. These studies offer insights on the potential use of a selected group of luminescent beetles found in this region as nocturnal environment bioindicators.

Ressignificação existencial do pretérito e longevidade humana / Existential meaning of the past, and human longevity

Existem, atualmente, mais de 300 hipóteses relativas à caracterização, função e mecanismos do envelhecimento, possivelmente devido ao aumento de idosos no mundo. Embora se avente uma função social à velhice humana, as transformações da sociedade impuseram uma cultura de descarte, incluindo pessoas como os idosos. Tal exclusão, que se associa à tristeza, depressão e morte desse grupo, é contraditória ao aumento do tempo de vida dos idosos constatado atualmente. O presente trabalho tentou determinar os aspectos ambientais envolvidos na longevidade usando uma técnica de metodologia qualitativa denominada grounded theory (ou teoria fundamentada nos dados) em dados fornecidos por ex-ferroviários longevos. Constatou-se que as representações dos ex-ferroviários confluem para a categoria central: desolação pelo aniquilamento da vida e do ambiente, no presente, devido à continuada negligência do Estado e da Sociedade na promoção e preservação das coisas boas para a vida que havia no passado. Observou-se ainda que, paralelamente à hipervalorização genérica das coisas do passado, há constatação recente de que suas existências fizeram parte da epopeia que promoveu o desenvolvimento econômico e social do interior paulista e possibilitou uma ressignificação existencial do passado, sugerindo ser um potente mecanismo de defesa que culmina em longevidade. Tal achado se insere na hipótese de que a função da longevidade seria a de preservar um contingente social com conhecimentos de um modo de vida que deu certo por ser socialmente vantajoso.

Nowadays there are more than 300 hypotheses to explain ageing characteristics, function and mechanisms, possibly due to the large and increasing number of old people in the world. Though having a social function attributed to elders, transformations - under way currently in society - have imposed a discard culture, including old people. This is an authentic exclusion that is frequently associated with sadness, depression and death in its group, contradicting the alleged idea that older people increase life-time (as has been observed in recent years). This manuscript has the aim of determining environmental aspects involved with longevity; it thus uses "grounded theory", a technique of qualitative research method, operating on data provided by elderly former railroad workers. It was observed that former railroad worker's social representations convey to a central category: desolation from perceiving life and environmental annihilation due to continuous State and Society negligence to promote and preserve good things - that existed in the past. We can also observe that, in a parallel way, by hyper valorizing past things, they recognize their existence as part of an epic process that promoted the São Paulo state countryside economic and social development, with an existential meaning to the past, which suggests to be a strong defense mechanism that contributes to longevity. This finding can be included in the hypothesis that the function of longevity would be to preserve a social contingent with knowledge about a way of life that was successful because it was socially advantageous.

Ferrovias, doenças e medicina tropical no Brasil da Primeira República / Railroads, disease, and tropical medicine in Brazil under the First Republic

Aborda o impacto da malária no âmbito da modernização republicana, basicamente nas ferrovias, que asssumiram então o papel de integrar o território e operar a expansão simbólica e material da nação brasileira. Os cientistas destacados para debelar os surtos epidêmicos não se limitaram a realizar as campanhas. Fizeram observações sobre aspectos da doença, inclusive suas relações com hospedeiros e ambientes, contribuindo com novos conhecimentos e com a institucionalização, no Brasil, de novo campo que então se estabelecia nas potências coloniais européias: a medicina tropical. O artigo articula essas inovações - especialmente a teoria da infecção domiciliária - com as campanhas em prol de ferrovias e com estágio subseqüente no enfrentamento da malária no Brasil, nos anos 1920.

The article explores the impact of malaria on infrastructure works - above all, railroads - under the republican drive towards modernization. Railways helped tie the territory together and foster the symbolic and material expansion of the Brazilian nation. The scientists entrusted with vanquishing such epidemic outbreaks did not just conduct campaigns; they also undertook painstaking observations of aspects of the disease, including its relations to hosts and the environment, thus contributing to the production of new knowledge of malaria and to the institutionalization of a new field in Brazil, then taking root in Europe's colonies: "tropical medicine." The article shows the ties between these innovations (especially the theory of domiciliary infection) and the sanitary campaigns that helped the railways, which in the 1920s were followed by a new phase in Brazil's anti-malaria efforts.

A 10-Year Review of Railway-Related Fatalities / 대한법의학회지

A study of accidental railway-related fatalities was performed using the case files of the Office of the National Institute of Scientific Investigation, Seoul, Korea, during the years 1992-2002 revealed 54 cases in which either a train caused death or in which a body was found dead by the tracks. To describe the features of railway-related deaths, I reviewed autopsy, and accident report data on all such deaths. Of the total 54 railway-related deaths, men accounted for 87% of the deaths. The manners of deaths were as follows: 23 were suicides, 2 were the result of criminal violence, 9 were accidents, and 20 were due to other causes. Most railway fatalities were among men between the age of 20-40 years. Many railway related fatalities occurred under 9 o'clock and over 22 o'clock. A blood alcohol concentration >0.05 % was found in 30 cases. Fatal railway injury is characterized by extensive disruption of more than one body region. A discussion ensues concerning the most common type of accidental railway-related fatalities, why they occur, and what future work remains in order to avoid such fatalities. Evidently, fatalities more frequently result from suicides, and then victims' disregard for safety. In conclusion, it is hoped that this article will serve as a catalyst for future research on this subject.
