Territorialisation and power in Portuguese America. The creation of comarcas (16th-18th centuries)

The general aim of this article is to analyse the political organisation of the territory in Portuguese America from the start of the building up of the Crown judiciary system from in the 16th to the 18th centuries and to look into the causes of its belatedness in comparison to what happened in Spanish America. The focus will however be on the comarcas through the reconstitution of the process leading to the setting up of these judiciary divisions. Four stages of this process will be identified and discussion will ensue over the social and political contexts in which these political and administrative novelties came to happen. It is claimed that the delay in the structuring of the judicial network in the States of Brazil and Maranhão stems from the fact that the Portuguese advance into the territories took place at a later stage. The comparisons between the two systems will also bring other differences to the fore, not least the greater rigidity of the Spanish model in contrast to the more experimental character of the Portuguese one, and the resilience found to exist in the donatarial system. It is also worth to point out that given solutions were the result of the will of central power as much as of local initiative, and it is suggested that the building up of the crown’s political apparatus (in which the judiciary network is included) brought about the connivance,albeit ephemeral, of social interests which are considered contradictory or irreconcilable by some authors.

On the Chemical Signature and Origin of Dicoppertrihydroxyformate (Cu2(OH)3HCOO) Formed on Copper Miniatures of 17th and 18th centuries

A corrosion product rarely reported in the literature has been found on the copper support of three miniature paintings of the 17th and 18th centuries. This product, which has been identified as dicoppertrihydroxyformate (Cu2(OH)3HCOO), is an unusual basic copper formate found on copper artifacts. The identification and characterization of dicoppertrihydroxyformate was carried out directly over the corroded surface of the objects, using a nondestructive approach, which combines the integrated use of various microanalytical techniques. Using this approach, it was possible to obtain a set of new reference data about the natural form of Cu2(OH)3HCOO, that will enable its unambiguous identification in other similar objects. In this work, the probable causes that may have contributed to its formation are also discussed.

OntoSPARES: da linguagem natural às ontologias. Contributos para a classificação automática de dados históricos (séc. XVI-XVIII)

O processamento de linguagem natural e as ontologias são ferramentas cuja interação permite uma melhor compreensão dos dados armazenados. Este trabalho, ao associar estas duas áreas aos elementos disponíveis numa base de dados prosopográfica, tornou possível identificar e classificar relacionamentos entre setores de ocupação na forma como eram designados na época, setores de atividade num formato mais próximo do de hoje e o estatuto social que essas incumbências tinham na sociedade coeva. Os dados utilizados são sobretudo de membros do Santo Ofício – do século XVI ao século XVIII. Para atingir este objetivo utilizaram-se algumas descrições textuais de ocorrências da época e outras pouco estruturadas, disponíveis no repositório SPARES. A aplicação de processamento de linguagem natural (remoção de stopwords e aplicação de stemming), conjugada com a construção de duas ontologias, tornou possível classificar esses dados, permitindo consultas mais eficazes. Ao contribuir para a classificação automática de dados históricos, propõem-se metodologias que podem ser aplicadas em dados de qualquer outra área do conhecimento, especialmente as que lidam com as variáveis de tempo e espaço de forma mais intensa; Abstract: OntoSPARES: from natural language to ontologies Contributions to the automatic classification of historical data (16th-18th centuries) The interaction between the natural language processing and ontologies are tools allowing a better understanding of the data stored. This work, by combining these two areas to the elements available in a prosopographic database, has made possible to identify and classify relationships between occupations of many individuals (in general Holy Office members of the 16th-18th centuries). To achieve this goal the data used was gathered in SPARES repository, including some textual descriptions of the time occurrences. They are all few structured. The application of natural language processing (stopwords removal and stemming application), combined with the construction of two ontologies, made possible to classify those data, allowing a more effective search. By contributing to the automatic classification of historical data, this thesis proposes methodologies that can be applied to data from any other field of knowledge, specially data dealing with time and space variables.

The culture of background investigations (Portugal, 1570-1773)

This article seeks to justify why it is possible to speak about a culture of background investigations in Portugal, or even in the Iberian Peninsula, especially in the 17th-18th centuries. It will emphasize three points: the huge number of people who made qualifications in Portugal and in the overseas Empire; how it created specialized knowledge and the need for specialized officers to deal with it; to demonstrate how the culture of qualification conditioned behaviors in different social groups.

Conservation Agriculture and its contribution to the achievement of agri-environmental and economic challenges in Europe

Conservation Agriculture is an ecosystem approach to farming capable of providing solutions for numerous of the agri-environmental concerns in Europe. Certainly, most of the challenges addressed in the Common Agriculture Policy (CAP) could be tackled through Conservation Agriculture (CA). Not only the agri-environmental ones, but also those concerning farmer and rural communities’ prosperity. The optimisation of inputs and similar yields than conventional tillage, make Conservation Agriculture a profitable system compared to the tillage based agriculture. Whereas this sustainable agricultural system was conceived for protecting agrarian soils from its degradation, the numerous collateral benefits that emanate from soil conservation, i.e., climate change mitigation and adaptation, have raised Conservation Agriculture as one of the global emerging agrosciences, being adopted by an increasing number of farmers worldwide, including Europe.

Occurrence of the pinewood nematode, Bursaphelenchus xylophilus in Portugal and perspectives of the disease spread in Europe.

In 1999, the pinewood nematode (PWN) , Bursaphelenchus xylophilus was found and identified for the first time in Portugal and in Europe. Following detection, Portuguese authorities initiated the implementation of eradication measures during 1999 and 2000, following an alert provided to European Community officials; as a result, the nematode was confirmed to be confined in the Setúbal region, near Lisbon. A task force from the follow-up group (GANP) created by the Secretary of State for the Rural Development established a national eradication programme (PROLUNP) to (1) Contain PWN within the initial geographic limits; (2) Implement eradication measures; and (3) Monitor PWN at a national level. Research is presently being conducted both at universities as well as research institutes, focusing on the characterization ofBursaphelenchus species associated with maritime pine, as well as on the insect vector, Monochamus galloprovincialis. Recent reports indicate that the nematode may be present in Siberia (Russia), which would present a threat to Eastern European forestry. Efforts are presently being developed by several European countries to establish a research consortium to detect and study the possible presence of PWN, for a new PRAs. A recent workshop held in Portugal, in 2001, has been an oportunity for sharing experiences and techniques on detection and control. There is clearly a greater awareness of this issue in Europe.
