A Primeira Edição Portuguesa d’O Príncipe ou o Maquiavel Fascista de Francisco Morais

A primeira edição portuguesa d' O Príncipe , de Maquiavel, viu a luz em 1935, mais de quatrocentos anos após a publicação original italiana. Apareceu sob a forma de “edição política”, que, naquela precisadata apresentava ao leitor português um Maquiavel fascista, prefaciado pelo próprio Mussolini. Em que conjuntura política e ideológica se inscreveu a edição? Como se apresenta e que sentido teve a apropriação ideológica de Maquiavel? Que méritos tem a tradução? Quem foi Francisco Morais, o organizador, tradutor e anotador da princeps portuguesa? E, finalmente, que futuro teve esta, em Portugal? Eis algumas das questões a que este texto procura dar resposta.

Os remeiros do São Francisco na literatura

Ao longo de dois séculos, os remeiros contribuíram para a formação e o desenvolvimento do sistema econômico regional no Médio São Francisco. Por sua importância social, foram mencionados por viajantes e técnicos em seus relatos sobre a região. Mas o trabalho, as crenças, a posição social dos remeiros podem ser conhecidos também por intermédio da literatura de ficção: estão presentes no conto e no romance regionalistas. Assim, utilizamos essas fontes para dar continuidade ao nosso trabalho de interpretação iniciado no livro Navegantes da integração: os remeiros do rio São Francisco, no qual utilizamos sobretudo o recurso metodológico de entrevistas. No presente artigo, os relatos e a literatura de ficção são confrontados com as informações do livro acima mencionado.

Environmental exposure to toxicants mixtures from a multi-purpose estuary: perspectives for a biomonitoring study in Portugal

This work was focused on a multi-purpose estuarine environment (river Sado estuary, SW Portugal) around which a number of activities (e.g., fishing, farming, heavy industry, tourism and recreational activities) coexist with urban centres with a total of about 200 000 inhabitants. Based on previous knowledge of the hazardous chemicals within the ecosystem and their potential toxicity to benthic species, this project intended to evaluate the impact of estuarine contaminants on the human and ecosystem health. An integrative methodology based on epidemiological, analytical and biological data and comprising several lines of evidence, namely, human contamination pathways, human health effects, consumption of local produce, estuarine sediments, wells and soils contamination, effects on commercial benthic organisms, and genotoxic potential of sediments, was used. The epidemiological survey confirmed the occurrence of direct and indirect (through food chain) exposure of the local population to estuarine contaminants. Furthermore, the complex mixture of contaminants (e.g., metals, pesticides, polycyclic aromatic hydrocarbons) trapped in the estuary sediments was toxic to human liver cells exposed in vitro, causing cell death, oxidative stress and genotoxic effects that might constitute a risk factor for the development of chronic-degenerative diseases, on the long term. Finally, the integration of data from several endpoints indicated that the estuary is moderately impacted by toxicants that affect also the aquatic biota. Nevertheless, the human health risk can only be correctly assessed through a biomonitoring study including the quantification of contaminants (or metabolites) in biological fluids as well as biomarkers of early biological effects (e.g., biochemical, genetic and omics-based endpoints) and genetic susceptibility in the target population. Data should be supported by a detailed survey to assess the impact of the contaminated seafood and local farm products consumption on human health and, particularly, on metabolic diseases or cancer development.

O encontro de Antero com S. Francisco de Assis: breves notas subsidiárias

Cristão por inspiração íntima e católico por filiação institucional, a relevância da personalidade de S. Francisco de Assis estende-se para lá do domínio estritamente religioso. Profundamente pertencentes ao espírito do seu tempo, o pensamento e a obra do Santo de Assis assumem uma importância extrema na viragem social e espiritual a que a Idade Média assistiu por volta dos séculos XII e XIII. Tido por alguns dos mais importantes intérpretes medievalistas como o inventor do sentimento medieval da natureza, S. Francisco motivou fervorosas adesões à sua espiritualidade e, simultaneamente, assumiu grande relevância enquanto modelo e inspiração nas reflexões de escritores e espiritualistas ocidentais. A sua valorização da natureza, fruto do extravasamento ôntico do ideal cristão de fraternidade, foi perfilhada pelos autores do século XIX, ávidos de uma reabilitação naturalista. Nomes como Chateaubriand e Lamartine, escritores da moderna França cristã e ambos adeptos do rousseauniano culto da natureza, aproximam as suas obras do encomiástico discurso franciscano face à obra de Deus, ainda que nem todos assumam na íntegra a perspectiva de S. Francisco. Mas não é apenas além-fronteiras que se verifica a importância da espiritualidade do Poverello.

Environmental data management in the Sado Estuary

Estuaries are perhaps the most threatened environments in the coastal fringe; the coincidence of high natural value and attractiveness for human use has led to conflicts between conservation and development. These conflicts occur in the Sado Estuary since its location is near the industrialised zone of Peninsula of Setúbal and at the same time, a great part of the Estuary is classified as a Natural Reserve due to its high biodiversity. These facts led us to the need of implementing a model of environmental management and quality assessment, based on methodologies that enable the assessment of the Sado Estuary quality and evaluation of the human pressures in the estuary. These methodologies are based on indicators that can better depict the state of the environment and not necessarily all that could be measured or analysed. Sediments have always been considered as an important temporary source of some compounds or a sink for other type of materials or an interface where a great diversity of biogeochemical transformations occur. For all this they are of great importance in the formulation of coastal management system. Many authors have been using sediments to monitor aquatic contamination, showing great advantages when compared to the sampling of the traditional water column. The main objective of this thesis was to develop an estuary environmental management framework applied to Sado Estuary using the DPSIR Model (EMMSado), including data collection, data processing and data analysis. The support infrastructure of EMMSado were a set of spatially contiguous and homogeneous regions of sediment structure (management units). The environmental quality of the estuary was assessed through the sediment quality assessment and integrated in a preliminary stage with the human pressure for development. Besides the earlier explained advantages, studying the quality of the estuary mainly based on the indicators and indexes of the sediment compartment also turns this methodology easier, faster and human and financial resource saving. These are essential factors to an efficient environmental management of coastal areas. Data management, visualization, processing and analysis was obtained through the combined use of indicators and indices, sampling optimization techniques, Geographical Information Systems, remote sensing, statistics for spatial data, Global Positioning Systems and best expert judgments. As a global conclusion, from the nineteen management units delineated and analyzed three showed no ecological risk (18.5 % of the study area). The areas of more concern (5.6 % of the study area) are located in the North Channel and are under strong human pressure mainly due to industrial activities. These areas have also low hydrodynamics and are, thus associated with high levels of deposition. In particular the areas near Lisnave and Eurominas industries can also accumulate the contamination coming from Águas de Moura Channel, since particles coming from that channel can settle down in that area due to residual flow. In these areas the contaminants of concern, from those analyzed, are the heavy metals and metalloids (Cd, Cu, Zn and As exceeded the PEL guidelines) and the pesticides BHC isomers, heptachlor, isodrin, DDT and metabolits, endosulfan and endrin. In the remain management units (76 % of the study area) there is a moderate impact potential of occurrence of adverse ecological effects and in some of these areas no stress agents could be identified. This emphasizes the need for further research, since unmeasured chemicals may be causing or contributing to these adverse effects. Special attention must be taken to the units with moderate impact potential of occurrence of adverse ecological effects, located inside the natural reserve. Non-point source pollution coming from agriculture and aquaculture activities also seem to contribute with important pollution load into the estuary entering from Águas de Moura Channel. This pressure is expressed in a moderate impact potential for ecological risk existent in the areas near the entrance of this Channel. Pressures may also came from Alcácer Channel although they were not quantified in this study. The management framework presented here, including all the methodological tools may be applied and tested in other estuarine ecosystems, which will also allow a comparison between estuarine ecosystems in other parts of the globe.

The 1531 Lisbon Earthquake: A Tsunami In the Tagus Estuary?

On 26 January 1531, a strong-magnitude earthquake heavily impacted Lisbon downtown. Immediately after the earthquake, the eyewitnesses reported large waves in the Tagus estuary, mainly north of the city and along the northern bank of the river. Descriptions include large impacts on ships anchored in the estuary and even morphological changes in the riverbed. We present a synthesis of the available information concerning both the earthquake and the water disturbance as a basis for the discussion of the probable tectonic source and the magnitude of the associated river oscillations. We hypothesize that the initial disturbance of the water can be attributed to the coseismic deformation of the estuary riverbed, and we use a nonlinear shallow water model to simulate the tsunami propagation and inundation. We show that the Vila Franca de Xira fault is the most probable source of the 1531 event. The largest inundation effects of the model correlate well with the historical descriptions: the impact is relevant in the inner Tagus estuary, but inundation in downtown Lisbon is small.
