Urban transport planning in a context of demographic, social, economic and technological change

Transport planning necessarily takes into account more than just the immediate time-frame. In the case of urban transport, planning needs to come up with solutions in regard to infrastructure which is expensive and may have a useful life extending over several decades. Therefore, planning must take note of economic, technological, social and demographic changes that influence trips undertaken.The purpose of this article is to explore some of the trends that may well be observed in upcoming decades. The article arrives at the conclusion that, in a period of considerable change and uncertainty, failure to take heed of recent trends may result in the construction of infrastructure that is not always the most appropriate and, what is more, that urban development militates against the efficient operation of public transport and, as a result, is likely to jeopardize the sustainability of cities in the long term.

Technological capacity-building in unstable settings: Manufacturing firms in Argentina and Brazil

From the 1970s onward, the macroeconomic context in Argentina and Brazil was characterized by drastic economic changes and instability. Numerous studies have documented the generally negative effect of this environment on the innovation capacities of the manufacturing sector. This paper, however, analyses the possible emergence of new innovation capacities in the period, bringing two important phenomena to light. First, a quite substantial number of firms, even in unstable settings, redoubled their innovation efforts. Second, these firms are mainly found in a small group of sectors associated with the countries’ static advantages or in sectors favoured by specific sectoral regimes. The findings, although exploratory, are a contribution to the debate on the development of innovative capacities in unstable macroeconomic contexts and the ability of sectors associated with the two countries’ static advantages to generate spaces of innovation and value creation.

International technological dynamics in production sectors: An empirical analysis

A new methodology is proposed for evaluating the economic development opportunities associated with the different industries making up a country’s economic structure. To this end, neo-Schumpeterian concepts are used to reinterpret the tools afforded by the “product space” literature in an attempt to assess the technological pervasiveness and sophistication of different production sectors. The ultimate objective is to develop a description of today’s techno-productive paradigm and the differential role that the various sectors play in it. An analysis of export data from 113 countries and territories for 2005-2009 indicates that the key sectors in the world economy are: industrial machinery, scientific and medical instruments, and pharmaceuticals. The strong performance of sectors based on mature technologies suggests that key sectors originating in different stages in history can survive and overlap one another, much like geological strata, owing to the persistence of older technological systems.

Trajetórias tecnológicas e sistemas agrários: qualificação territorial utilizando geoprocessamento em Paragominas e Santarém/PA

A Amazônia tem sido observada principalmente por meio do fenômeno do desmatamento, utilizando recursos tradicionais do sensoriamento remoto como a quantificação de área desflorestada e seu posterior incremento anual, que parece se constituir em uma metodologia eficaz. Ratificando este raciocínio, constatei num levantamento de 16.591 multas aplicadas pelo IBAMA/PA no período de 2000 até 2008, que mais de 85,0% das autuações estavam relacionadas apenas à componente flora;e na jurisdição da Gerência do IBAMA em Santarém, oeste do Pará, em 2008, quase 60% das multas se deu por conta de desflorestamento, identificados via sensoriamento remoto. Ressalta-se que as análises de imagens de satélites por si só não definem elementos da superfície terrestre, contribuindo pouco para o entendimento e posterior intervenção da realidade. Nesse contexto, foram investigados e vetorizados 479 estabelecimentos rurais nas regiões de Paragominas e Santarém, estado do Pará, que possuem históricos de uso e ocupação distintos, qualificando-os segundo suas trajetórias tecnológicas prevalentes, na perspectiva apresentada por Costa, concretizando um importante passo para correção das distorções no desenvolvimento econômico, agregando informação ao dado de sensoriamento remoto. Aplicaram-se recursos geotecnológicos de métricas de paisagem, construíram-se banco de dados celular integrado com estatísticas e algoritmos de otimização probabilística, associando dados de classificação não supervisionada isodata (validadas com kappa= 0,87, classificação considerada“excelente”) com os tipos de produção coletados em campo, gerando uma classificação final "integrada"(kappa= 0,78, classificação “muito boa”). Na região de Paragominas, foram qualificadas 3 tipos de trajetórias tecnológicas, a camponesa T8 (domínio de culturas temporárias), a camponesa T3 e patronal T4 (especializadas em pecuária de corte). Em Santarém, revelaram-se 2 trajetórias, a camponesa T2 (forte presença de culturas permanentes, temporárias e sistemas agro florestais) e a patronal T7 (mutação da T4, aumentando a participação das culturas temporárias). A metodologia aplicada logrou êxito, espacializando as propriedades rurais segundo seus tipos de trajetórias tecnológicas e gerando classes de uso mais representativas, como cultura temporária e pastagem, mas que na classificação via sensoriamento remoto isodata é englobada pela classe “agropecuária”, possibilitando uma visão mais realista das atividades de produção desenvolvidas na área investigada, concretizando a geração de informações espaciais integrando dados de diferentes fontes e o aumento do poder de leitura do pixel.

Ceramic raw materials from the State of Maranhão, Brazil. Part 1: chemical and mineralogical characterization and technological properties of clays from São Luis, Rosário, Pinheiro and Mirinzal

Nesse trabalho, foram caracterizadas algumas argilas coletadas nos municípios de São Luís, Rosário, Pinheiro e Mirinzal. A caracterização foi realizada através dos ensaios de difração de raios X, massa específica real, capacidade de troca de cátions (CTC), área superficial, distribuição granulométrica, análise química, análise térmica (TG-DTA) e limites de Atterberg. Ensaios tecnológicos de retração linear, antes e após a queima, absorção de água e tensão de ruptura a flexão, em três pontos, foram realizados em corpos de prova prensados uniaxialmente a 20 MPa e tratados termicamente em 850, 950, 1050, 1150 e 1250ºC. Os resultados obtidos permitiram identificar duas argilas de queima branca, constituídas de quartzo, caolim, feldspato e anatásio, com excelentes propriedades para uso em cerâmica branca. As restantes são queima vermelha e possuem composição mineralógica de quartzo, caolim, feldspato, montmorilonita, hematita e goetita. Estas últimas apresentaram valores moderados de plasticidade e são adequadas para aplicações em cerâmica vermelha.

Government procurement policy in developing countries: the case of Petrobras

The aim of this article is to discuss whether public procurement policy can promote innovation by firms located in developing countries. The literature on technological learning is used to create a typology for assessing the impact of public procurement in developing countries from the standpoint of innovation. Petrobras, a Brazilian state-owned enterprise, was chosen as a case study. Petrobras is a global leader in the field of deepwater oil production technology and so offers an interesting opportunity to investigate whether government procurement in developing countries is used to promote the capability of domestic firms to develop innovations. The article presents the findings of a field survey on P-51, a platform that was ordered by the Brazilian state-owned enterprise and began producing in 2009. The case study is based on information collected from interviews with managers of Petrobras, EPC contractors and some of the firms subcontracted to work on P-51.

TACTILE CARTOGRAPHY EXPERIENCES IN BRAZIL: METHODOLOGIES AND DIDACTICAL MATERIAL WITH TECHNOLOGICAL RESOURCES FOR INCLUSION OF BLIND AND LOW VISION STUDENTS

The tactile cartography is an area of Cartography that aims the development of methodologies and didactical material to work cartographic concepts with blind and low vision people. The main aim of this article is to present the experience of Tactile Cartography Research Group from Sao Paulo State University (UNESP), including some didactical material and courses for teachers using the System MAPAVOX. The System MAPAVOX is software developed by our research group in a partnership with Federal University of Rio de Janeiro (UFRJ) that integrates maps and models with a voice synthesizer, sound emission, texts, images and video visualizing for computers. Our research methodology is based in authors that have in the students the centre of didactical activity such as Ochaita and Espinosa in [1], which developed studies related to blind children's literacy. According to Almeida the child's drawing is, thus, a system of representation. It isn't a copy of objects, but interpretation of that which is real, done by the child in graphic language[2]. In the proposed activities with blind and low vision students they are prepared to interpret reality and represent it by adopting concepts of graphic language learned. To start the cartographic initialization it is necessary to use personal and quotidian references, for example the classroom tactile model or map, to include concepts in generalization and scale concerning to their space of life. During these years many case studies were developed with blind and low vision students from Special School for Hearing Impaired and Visually Impaired in Araras and Rio Claro, Sao Paulo - Brazil. The most part of these experiences and others from Brazil and Chile are presented in [3]. Tactile material and MAPAVOX facilities are analysed by students and teachers who contribute with suggestions to reformulate and adapt them to their sensibility and necessity. Since 2005 we offer courses in Tactile Cartography to prepare teachers from elementary school in the manipulation of didactical material and attending students with special educational needs in regular classroom. There were 6 classroom and blended courses offered for 184 teachers from public schools in this region of the Sao Paulo state. As conclusion we can observe that methodological procedures centred in the blind and low vision students are successful in their spatial orientation if use didactical material from places or objects with which they have significant experience. During the applying of courses for teachers we could see that interdisciplinary groups can find creative cartographic alternatives more easily. We observed too that the best results in methodological procedures were those who provided concreteness to abstract concepts using daily experiences.
