Parentesco, redes familiares y sociabilidad en el mundo hispanoamericano en los siglos XVII y XIX

Hasta hace algunos años, el interés por la historia de la familia, aunque no era escaso, estaba orientado a enfoques de tipo macrohistórico, ya que el énfasis estaba puesto en las estructuras de la sociedad. La dominación de los planteamientos cuantitativistas impuestos por los Annales, así como la fuerte influencia del marxismo, coadyuvaron en la consideración de la familia, no como objeto de investigación en sí misma, sino como expresión o ilustración de un funcionamiento económico social global. Los numerosos y excelentes trabajos sobre la élite colonial americana ejemplifican esta clase de acercamiento, fundamentado a partir de una reflexión acerca de los grupos sociales definidos en base a criterios socio-económicos. De la misma marreta, si la familia servia de base a los estudios de demografía histórica,lo que se pretendía a través de ella era la deconstrucción de modelos de comportamiento demográfico para un espacio definido. Fuera de estos planteos con sesgos estructuralistas y funcionalistas, la historia de la familia fue el refugio de la historiografia más tradicional y a veces rancia, fundada muchas veces en la aplicación de la reconstrucción genealógica como único método de estudio de los sectotes sociales más poderosos a nivel económico o político.

A questão da inovação em fármacos no Brasil: proposta de criação do programa nacional de fármacos (Pronfar)

Medicines are essential instruments to the preservation, maintenance and promotion of Health. The access to the medicine represents an important factor of social inclusion, depending on the availability of the pharmaceutical - active principle contained in the medicine that in 85% of the cases has a synthetic origin. In this scenario the importance of knowing how to make pharmaceuticals and medicines plays a significant role for the viability of the autonomous Health politics necessary for the demands of the major Nations. In this context, this work describes concisely the main aspects involved in the interdisciplinary drug discovery process, identifying the possible gorges for the successful development of innovative drugs in Brazil.

Aspectos e fatores da produtividade em pesquisa, desenvolvimento e inovação

Comparison of national budgets for R&D is often made but it should consider the relative productivity and their factors. In Brazil, inefficiency factors as well as their causes have been diagnosed since the late 60's and solutions have been proposed within various governmental organisms, from CNPq to the strategy think tanks. Problems that hinder R&D and innovation in Brazil are reviewed from a historical perspective together with the proposed solutions providing a detailed analysis of the difficulties that have to be overcome to achieve a more effective innovation environment, adequate for the present times, challenges and opportunities.

Inovação tecnológica e produção no setor químico

Innovation is the main tool for competitiveness and growth in the chemical sector and the main factors for innovation activities in industry as well as the innovation dynamics are discussed in this paper. Success indicators of innovation in Oxiteno are the following: 54% of the current production derives from RD&E projects, 11% of the gross margin in the internal market is due to new products, the company is a technology licensor, holding 17 patents and keeping a strong participation in the production and service sales in the high technology catalysts area, beyond its core petrochemicals and surfactants area.

O Quadrante de Ruetsap e a anti-ciência, tecnologia e inovação

The concept of research and the controversy among classical models for C, T & I, outdated by the development of knowledge and Post-modern society needs were revisited through the (3) Quadrants advanced by Donald Stokes in the mid-nineties. The scientific community to fit into these Quadrants was faced with many difficulties and reacted by issuing pseudo-facts, accepted by under-prepared technocrats as viable justifications for conducting research in face of these new paradigms. In a poor country full of contrast and needs such as Brazil, this attitude satisfies the bureaucracy and academic elite, but frustrates government and society, that do not get, in the expected measure, the benefits of their commitment with the Teaching, Research and Extension Sectors mainly embedded in the Public University system. An extension, in fact a contradictory approach, to Pasteur's Quadrant, is proposed to characterize this situation: The Syndrome of Ruetsap's Quadrant.

A importância do observatório de atividades industriais vis-à-vis tendências em ciência, tecnologia e inovação

Given that innovation is fundamental for competitiveness, and that it is intrinsically linked to knowledge, it has become essential to foster effective interaction between the Brazilian productive sector and universities and R&D centers. This interface should be created by means of the model used in developed countries: Observatory of Industrial Activities and Trends in Science, Technology and Innovation. The present work describes its main functions, using examples of activities undertaken by the Chemical Industry Information System of the Federal University of Rio de Janeiro related to production systems of primary and high-tech industries, examining the diffusion of knowledge to decision-makers.

Desempenho físico-químico de metais e estruturas de concreto de redes de distribuição de energia: estudo de caso na região de Manaus

The influence of natural aging furthered by atmospheric corrosion of parts of electric transformers and materials, as well as of concrete poles and cross arms containing corrosion inhibitors was evaluated in Manaus. Results for painted materials, it could showed that loss of specular gloss was more intensive in aliphatic polyurethane points than in acrylic polyurethane ones. No corrosion was observed for metal and concrete samples until 400 days of natural aging. Corrosion in steel reinforcement was noticed in some poles, arising from manufacturing faults, such as low cement content, water/cement ratio, thin concrete cover thickness, etc. The performance of corrosion inhibitors was assessed by many techniques after natural and accelerated aging in a 3.5% saline aqueous solution. The results show the need for better chemical component selection and its concentration in the concrete mixture.

Redes de acción : el caso de Birmania

El objetivo del presente ensayo es analizar el papel de las nuevas tecnologías en la formación de redes de acción. Para ello, comenzaré analizando brevemente ciertos puntos y características de las redes de acción y sus tipos, para a continuación, centrar el análisis en un caso real y de ardiente actualidad, como es el caso de Birmania.Una red de acción es un sistema que interconecta nodos. Estos nodos son autónomos y autoorganizados, de manera que cada uno de ellos aporta información y la red se encarga de intercambiar dicha información proveniente de los distintos nodos, así como proyectarla hacia espacios mayores de interacción. Por lo tanto, una red es un sistema exógeno, en la medida que trabaja en la búsqueda constante de interacciones e intercambios mas allá de sus propias fronteras. Las redes responden a la necesidad de conversar con otros para producir acuerdos, arreglos y consensos. Por lo que la red precisa de la polivalencia y la capacidad de adquirir nuevas competencias, por parte de los sujetos que la forman.

Las redes de innovación docente de la Universitat de Girona : la perspectiva de los coordinadores

In 2009 the University of Girona (Spain) created four interest groups on teaching innovation. The objective of the project is that lecturers with an interest in teaching innovation can exchange their points of view and learn from one another, so University teaching is improved as a result. There are four such groups: “Problem based learning (ABP)”, “Cooperative learning”, “Evaluation”, and “Information and Communication Technologies (ICTs) and Teaching”. The coordinators of the groups or networks, as they are also called, are chosen on a free basis by its members. This paper presents their point of view as regards the current activity of encouragement of interest in higher education and they elaborate on the main difficulties involved. The implications of the interdisciplinary work are explored, as well as the challenges of an initiative of this kind. The evolution of the ongoing work is reviewed, taking into account the context of a changing University, the lack of previous experience regarding projects of this kind, the asynchronous communication among the participants, and the necessity of a flexible approach in organizational matters

A tabela periódica dos elementos químicos prevista por redes neurais artificiais de Kohonen

Although several chemical elements were not known by end of the 18th century, Mendeleyev came up with an astonishing achievement: the periodic table of elements. He was not only able to predict the existence of (then) new elements but also to provide accurate estimates of their chemical and physical properties. This is certainly a relevant example of the human intelligence. Here, we intend to shed some light on the following question: Can an artificial intelligence system yield a classification of the elements that resembles, in some sense, the periodic table? To achieve our goal, we have fed a self-organized map (SOM) with information available at Mendeleyev's time. Our results show that similar elements tend to form individual clusters. Thus, SOM generates clusters of halogens, alkaline metals and transition metals that show a similarity with the periodic table of elements.

Aproveitamento sustentável de biomassa e de recursos naturais na inovação química

Increased production of biomass is currently the only immediately accessible alternative for large-scale carbon sequestration and it can produce large amounts of food, fuel and raw materials for the chemical industry that can in turn growingly replace oil as a source of organic building blocks and also of hydrogen and sulfur. Development of processes for biomass and abundant minerals transformation into chemical raw materials should now benefit from large inputs from nanotechnologies, biotechnologies, information and micro-reactor technologies. Success in R&D&Innovation along this line can yield new products and processes needed to perform desirable functions within a sustainable development paradigm.
